大发 www.paulmartinezmusic.com FGY high position Car Dumper hydraulic transmission, High position through a new replacement equipment, powder materials This machine is placed in the ground phase with the rails of tramcar transportation, With the type of MGC 1T, 1.5 T, 3T fixed compartment car, the car held on the side in the truck loaded with minerals or other transport equipment.
The machine has simple structure, light weight, small volume, great loading capacity, stable operation, easy to operate and install the basis of a simple, complete handling and so on.
The unloading operation of the machine directly, without the intermediate store and other facilities, the less investment.Quick, areas with high groundwater or coal gangue dump trucks and cans of mine car exports more appropriate.Not only simplify the original production processes, but also by the larger economic benefits, the protection of the environment, the eradication of the most ideal equipment of coal gangue dump.
2. The series of varieties and technical characteristics of high position Car Dumper hydraulic transmission
A series of 2.1 varieties of high position car dumper
Four varieties of high position car dumper is divided into three categories:
(I) 1 tons of high position car dumper wagon gauge of 600 mm, for FGY1.0/6.
(1.5 Tons of high position car dumper cars:
600 Mm gauge FGY1.5/6;
900 Mm gauge FGY1.5/9.
(3 Tons of high position car dumper car as a gauge of 900 mm for the FGY3.0/9.
2.2 High position car dumper technical parameters shown in the following table
2.3 The implementation of the standards: MT/T685-1997 "high position car dumper"
3. The working principle and structure of high position Car Dumper hydraulic transmission
High position car dumper by the arm to undertake the car, push the arm rotated around the axis of rotation by overturning hydrauliccylinder, to promote the purpose of unloading mine car turnover reached a high of 145 degrees.Flip and landing with self-locking function Press the button and automatically rise or whereabouts of paper until after automatic stop, flip the stop button to stop at any position in the process of realizing the flipped.When overturning cylinder will be transferred to arm the location of the point of death, By supporting the reduction of cylinder reduction, And then by turning the hydraulic cylinder drive arm fall, when the jib to lift the car arresters is closed, to prevent sports car, the stop block after open reduction of arms in order to change mine.
This equipment consists of a host of car dumper and the hydraulic system is composed of two parts.Car dumper is composed of base, support arm, overturning hydrauliccylinder, baffle, reduction of cylinder bearing, thrust reduction, and the composition of car stop.
Hydraulic systemAccording to the characteristic of car dumper 1T, 1.5 T, 3T the tilting mechanism as the single pump (according to user's requirement for the use of dual-motor dual pump cycle) open-system single-acting sequence commutation circuit alone, Motor-operated switch to the natural heat dissipation (by use of the environment can add water-cooling or heating system), the choice of hydraulic components of advanced technology, reliable, and simple structure.
3.3 High position car dumper handling steps and indicator display
A. Turn on the power switch device of power supply, power indicator light is lit at the same time;
B. Press the machine "start" button, the pump motor start, and electric light;
C. A car after car into the car, press the "flip up" button, automatically roll over to the highest point of the automatic stop, Flip flip the light on in the process, "turn in place" lights up the place.
The specific steps are as follows:
(1) Click on the "flip up" button, at the same time "flip up" sign lights up.
To flip the bottom cavity filling the hydraulic oil cylinder, To promote rising, the piston, Push the arm flips, Reverse cylinder will be transferred to arm the location of the point of death, The question of its support beams and support the presumption of contact reduction, up to the highest position, magnetic proximity switches are connected to "flip" light up the place, and the cylinder piston rod is the pressure drop reduction;
(2) At the same time press the "play" button, the reduction of cylinder To reset the bottom of cavity filling the hydraulic oil cylinder, and "reset" light up the cylinders, to make them or adjusting oil cylinder stroke, and harvesters the completion of unloading of materials (clean):
Note: (1) reduction of cylinder take-off and landing as a button, press the run, let go to stop light at the same time.
(2) The revolving arm to rise, the rate of decline by one-way throttle valve in the hydraulic system to control the process of turnover can stop at any position.
D. Press the "reversal" button to automatically roll over to a lowest auto-stop, Flip flip the light on in the process, "flip" the light is left in place after place.
The specific steps are as follows:
(1) The starting cylinder press the "reset" button, the top bearing beam;
(2) At the same time press the "reversal" button, To turn on cavity filling the hydraulic oil cylinder, the piston down, push the arm flip, flip to the lowest magnetic proximity switches are connected to, "turn left in place" indicator light is automatically stopped.
4, The security of particular note:
The operation of the lift car is not in the middle of 4.1 is strictly prohibited.Car into the dumper must be in a safe place, that is, before and after wheel stop in the rail tank, there shall be no dislocation of before and after, left and right tilt parameter and so on.
Car stop operation state of the failure of 4.2 is strictly prohibited.Car must be flexible and reliable.Arm when the flip card to catch must be in the two rounds of the inside, to prevent out of the car.Go to the lowest point, the catch must be in the state of the release of the card.
4.3 In the course of rise or fall may stop at any position, is strictly prohibited to enter beneath the arm.
The operation of 4.4 motor, the rotor arm up, drop process, such as encountered an unexpected condition that you press the "stop" button, the whole electric control box off.
5. Installation and debugging of the high position Car Dumper hydraulic transmission
FGY1.0/6, FGY1.5/6, FGY1.5/9, FGY3.0/9 hydraulic high position car dumper is a brief introduction to the method of installation and debugging of pumping station and electric control:

5.3 Turning shaft oil cup need lubricating oil regularly, generally half a month at a time.
6. The maintenance of high position car dumper
6.1 The hydraulic oil in the tank, in the use of the process should be to maintain normal oil level height and clean, regular inspection, periodic replacement.The replacement period based on the use of the discretion of working conditions and environment, the tank not to accumulate rainwater and dust.
6.2 In order to guarantee the normal work of hydraulic system and hydraulic components are the specific situation, it is recommended to use:
46 # Anti abrasion hydraulic oil
6.3 Operation of oil tank oil temperature of the liquid in the context of 300C-600C appropriate.Not higher than the 600C, if the abnormal oil temperature rise, shall check and remove the faults.
6.4 In the operation when the abnormal noise of hydraulic system, should cease immediately, after a thorough examination and for removing the faults can be started using.
6.5 Installation commissioning in to the system to send the oil in the air at the same time the system must be removed in order to guarantee the smooth velocity of hydraulic cylinder.
6.6 To take over the service should secure connection is reliable to seal, to prevent the suction and leakage, and check the direction of rotation of the oil pump and the import and export right.
6.7 Buffer rubbers and anti-collision plate damage to the replacement should be timely; Check fastening bolts of the ministries or replacement.
7. The matters needing attention
7.1 Prohibition in turning operation within the region and avoid safety accidents.
When the system fault occurs in the status of the work of inspection and adjustment;
7.2 When the hydraulic system in trial operation and exhaust, the personal as far away from the high-pressure pipe and to avoid pressure oil spray direction.
7.3 Dumper must be installed on the basis of sufficient strength to prevent the tilt operation
