Debugging and using of the device:
1. examination before debugging
(1) Checking the brake: the magnitude of the braking force depends on the compression degree of the brake spring, and the brake spring is completely compressed, so that the maximum braking force can be achieved;
(2) checking the oil pipe joint: the deformation is avoided, the oil pipe joints are locked, the U-shaped clamp is inserted in place, and the U-shaped clamp cannot be pulled out through conventional pulling;
(3) checking each guide rail: the joint connecting part needs to be within the required dimensional tolerance and has no large deformation or dislocation, and the trolley and the hydraulic slide block can easily slide through the joint part;
(4) cable compresses tightly U type bolt: the cable is required to be compressed, and the cable cannot move relative to the U-shaped bolt in the process of pulling and bending;
(5) each trolley: the wheels of each trolley must rotate flexibly, and the trolley does not deviate relative to the guide rail;
(6) an oil pipe for supplying emulsion to the hydraulic actuating mechanism cannot touch any part of the conveyor below;
(7) each valve line has no blocking phenomenon and is sensitive to operation.
2. Commissioning of devices
After all the checks before debugging are finished, the equipment can be debugged if all the checks meet the requirements.
(1) The four wheels of the trolley are adjusted, the left and right stress of the trolley is uniform as far as possible due to the positions of the cables on the two sides of the trolley, and the trolley can be used if the front and the back of the trolley are pulled within the range of 3m without deviation. If the cable deviates, the positions of the cables on the two sides of the wheels and the trolley are adjusted, and the gravity center of the cable moves outwards until the cable does not deviate any more.
(2) The position of the cable is adjusted to ensure that when the main hydraulic cylinder is completely extended, the cable on the cable hanging ring of the main hydraulic cylinder is not stressed and does not interfere with other objects.
3. Use of the device
The use of the device mainly comprises the following points:
(1) operation of the manual directional valve: the forward function of the system can be completed by operating only one handle, if the reverse operation is needed, the reverse operation can be realized by still operating the handle after rotating the reversing knob.
(2) And an oil pipe joint, wherein a phi 10 interface is reserved on the high-pressure pipeline of the main pump station by a stop valve to serve as an oil inlet, and a phi 10 interface is reserved on the liquid return pipeline of the main pump station by the stop valve to serve as an oil return port.
Maintenance of equipment
1. Because the environment of the stope face is complex, coal blocks and pulverized coal often fall down, the track and the wheels need to be cleaned frequently to prevent the track face and the outer edges of the wheels from being bonded with too much coal dust, so that four wheels cannot contact the track face simultaneously or the wheels cannot rotate.
2. The various rotating parts are often inspected to see if the cotter pin is severely worn and if so, replaced. If conditions permit, a certain amount of lubricating oil can be applied to the rotating part.
3. Checking whether the U-shaped part is loose or not, and replacing and tightening the U-shaped part if necessary.
4. The equipment is used for more than three years, and the lubricating oil of the bearing needs to be replaced.
5. Checking whether each nut is loosened, whether the stop lug of the stop washer is clamped or not, and whether each round-link chain is seriously rusted or not.
Common fault and elimination
1. Leakage of hydraulic line
And replacing the O-shaped sealing ring.
2. Non-operation of hydraulic cylinder
(1) And (4) judging whether the liquid supply pressure is sufficient, namely 16-38 MPa.
(2) And (4) judging whether each valve and the oil pipe are blocked by foreign matters or not, and if so, dredging or replacing.
3. Lack of braking force
The pretension spring is too loose, and adjustable spring pretension nut further compresses tightly the spring, increases braking force, if the brake shoe block wearing and tearing are serious, then needs to be changed, and the track web has greasy dirt or water stain also can lead to the braking force not enough, should pay attention to the clearance.
4. The trolley does not have flexibility in sliding
Checking whether the rotating part is bonded with pulverized coal into blocks or not, and if so, clearing; if not, checking whether the bearing is stuck, if so, replacing the bearing.
5. Uneven deflection of cable
(1) First, it is checked whether the lengths of the traction links 8 are similar, which is caused by the different lengths of the links 8, and the use is not influenced.
(2) If the cable is uniform before and becomes different in length after being used for a period of time, the U-shaped bolt for fixing each cable is checked to see whether the cable is loosened or not, and if so, the cable is fastened again.
6. Cable drag is motionless
Checking whether each hanging cable, each connecting trolley and each brake mechanism are blocked with the track 1 or not, and if so, adjusting the deviation of the track 1.
The above descriptions are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to, replaced or changed.
