Description

Technical Field

[0001] The utility model relates to the technical field of endless rope winches, in particular to a safety-locked endless rope tail tensioning oil rod structure. Background Art

[0002] With the advancement of science and technology, coal mining is no longer carried out by manpower to transport the mined minerals out of the mine, but a more convenient and quicker method has emerged. Science and technology are the accelerators of labor production development. The current way of transporting minerals usually uses an endless rope winch for transportation. Through mechanization, the physical strength consumed by workers is reduced. However, in the process of using the endless rope winch, as time goes by, the wire rope used as the driving part will become loose, and the return wheel cannot be actively tensioned and adjusted, causing the winch drum to often slip, reducing the efficiency of transporting minerals. Utility Model Content

[0003] The utility model aims to provide a safety-locking infinite rope tail tensioning oil rod structure to solve the problem of winch slipping caused by elongation and relaxation of wire ropes caused by long-term use in the above-mentioned background technology.

[0005] Preferably, the sliding engaging mechanism includes: a ratchet rack, which is fixedly mounted on the outer surface of a side of the slide groove away from the rib plate frame, a rotating rod is rotatably mounted on one end of the mounting plate close to the shaft seat, and a ratchet block is fixedly mounted on the outer surface of the rotating rod, and the ratchet block is engaged with the ratchet rack, the mounting plate is engaged with the slide groove, and the side surface of the slide groove is in contact with the side surface of the ratchet block, a counterweight extension block is fixedly mounted on one end of the ratchet block close to the tensioning cylinder, and the outer surface of the counterweight extension block is in contact with the outer surface of the mounting plate.

[0006] By adopting the above technical solution, the steel cable can be pulled to drive the displacement ear so that the mounting plate can follow the movement. The counterweight extension block can be used to drive the rotating rod to rotate when the ratchet block passes through the ratchet rack, so that the ratchet block jumps through. When the mounting plate stops, the ratchet block and the ratchet rack are always engaged, so that the tensioning cylinder that pushes out the return wheel can quickly pre-tighten the steel cable inserted through the return wheel.

At this time, the ratchet block will be pressed down due to the deadweight of the counterweight extension block and engage with the ratchet rack, so that the counterweight extension block is close to the outer surface of the mounting plate. Then, the sliding block can be pushed out by starting the first hydraulic cylinder, so that the sliding block engages with the counterweight extension block, and the ratchet rack and the ratchet block are stuck. The ratchet rack and the ratchet block will not jump teeth due to unexpected vibrations, which will cause the steel cable to loosen and the winch to shift.

[0009] Preferably, a sliding mechanism is provided between the mounting plate and the rotating rod, and the sliding mechanism enables the rotating rod to rotate to loosen the mounting plate, so that the ratchet block is disengaged from the ratchet rack.

[0010] By adopting the above technical solution, when the steel cable is found to be over-tensioned after debugging, it can be adjusted through the sliding push mechanism, thereby reducing the probability of accidents caused by workers entering the rib frame for adjustment and improving the safety of the operation.

[0012] By adopting the above technical solution, when the steel cable is found to be over-tensioned after debugging, the first hydraulic cylinder can be contracted to disengage the sliding block from the counterweight extension block, and then the second hydraulic cylinder can be started to push out the rack block, so that the rack block meshes with the gear and drives the rotating rod to rotate, so that the ratchet rack disengages from the ratchet block, and then the steel cable of the shifting ear can be pulled to adjust the position of the mounting plate.

[0013] Preferably, a pushing mechanism is provided on a side of the tensioning cylinder away from the mounting plate, and the oil path of the tensioning cylinder is blocked by the pushing mechanism to ensure that the hydraulic oil in the tensioning cylinder does not escape through the pipeline.

[0014] By adopting the above technical solution, after fine-tuning the action of the tensioning cylinder, the oil pipeline in the tensioning cylinder can be disconnected to maintain the oil stock in the tensioning cylinder so that the oil in the tensioning cylinder will not leak through the pipeline and cause adjustment failure.

[0015] Preferably, the pushing mechanism includes: a solenoid valve, which is fixedly mounted on the outer surface of the end of the tensioning cylinder away from the return wheel, and a connecting pipe is fixedly mounted on the end of the tensioning cylinder away from the solenoid valve, and one end of the connecting pipe is connected to the solenoid valve, a stroke detection sensor is fixedly mounted on the end of the tensioning cylinder close to the rotating rod, and the stroke detection sensor and the tensioning cylinder are concentrically designed, and the stroke detection sensor passes through the piston of the tensioning cylinder, a pushing cylinder is fixedly mounted on the side of the solenoid valve close to the return wheel, and the output end of the pushing cylinder is connected to the pipeline movable block inside the solenoid valve.

[0016] By adopting the above technical solution, the stroke of the tensioning cylinder can be monitored by the stroke detection sensor, so that the tensioning cylinder can stop at the required position. At the same time, by starting the solenoid valve, the push cylinder can push the block in the solenoid valve, switch the pressurized oil circuit, and close the oil circuit channel of the tensioning cylinder.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the safety locked infinite rope tail tensioning oil rod structure:

[0018] 1. When installation is required, the steel cable passing through the displacement lug can be used to pull the mounting plate to move in the slide slot. As the mounting plate moves, the ratchet block will jump when passing through the ratchet rack. The counterweight extension block is used to make the ratchet block always fit with the ratchet rack after the jump. When the steel cable in the return wheel that has been pushed out is pulled up, the pulling of the mounting plate can be stopped. At this time, the ratchet block will be engaged with the ratchet rack due to the weight of the counterweight extension block, so that the counterweight extension block is close to the outer surface of the mounting plate, and the mounting plate is quickly fixed, so that the steel cable passing through the return wheel is pre-tensioned;

[0019] 2. After the steel cable in the return wheel is pre-tensioned, the ratchet rack and the ratchet block are engaged. At this time, the first hydraulic cylinder can be started to push out the sliding block, so that the sliding block is engaged with the counterweight extension block, and the ratchet rack and the ratchet block are locked, so that when vibration occurs, the ratchet rack and the ratchet block will not be unhooked, causing the steel cable to loosen and cause an accident;

[0020] 3. After the pre-tensioning is completed, the tensioning cylinder can be started, and the stroke detection sensor can be used to adjust the pulling stroke of the tensioning cylinder, so that the steel cable passing through the return wheel can be adjusted to a suitable tightness. The rotation of the tensioning cylinder and the shaft seat can alleviate the impact of the swaying of the steel cable in the return wheel on the tensioning cylinder. After that, the solenoid valve is started to drive the push cylinder to move, and the pipeline in the solenoid valve is switched to cut off the oil circuit connecting the tensioning cylinder and the connecting pipe to the external pipeline, so that the oil in the tensioning cylinder will not leak out through the pipeline, so that the steel cable in the return wheel can always remain in the set position;

[0021] 4. When the steel cable needs to be replaced or is pulled too tight, the first hydraulic cylinder can be contracted to drive the sliding block to retract, so that the sliding block and the counterweight extension block are disengaged. Then the second hydraulic cylinder can be started to push out the rack block, so that the rack block is engaged with the gear, and the rotating rod is pushed to rotate, so that the ratchet rack and the ratchet block are disengaged. Then the steel cable of the displacement ear can be loosened and the mounting plate can be pulled back, reducing the danger of workers entering the rib frame to adjust the tightness of the steel cable.
