Description

Technical Field

[0001] The utility model relates to a hydraulic oil tank structure of a rope-changing linear winch, belonging to the technical field of hydraulic oil tanks. Background Art

[0002] In the mine shaft hoisting system, the lifting, lowering and replacement of wire ropes are very frequent and risky. In recent years, special rope changing vehicles have begun to appear, greatly alleviating the pressure of this part of the work.

[0003] At present, most of the head rope changing vehicles have a double working unit structure with the hydraulic oil tank at the rear, while the tank rope and tail rope changing vehicles (linear winches) have a single working unit structure with the hydraulic oil tank at the side.

[0004] The design of the hydraulic oil tank seems simple, but there are many restrictions: 1. Due to the complexity of the equipment of the linear winch, and the restrictions on transportation width and height, the regular space left for the hydraulic oil tank is generally not large; 2. When the linear winch releases the rope, gravity works, and the heat is huge. In addition, the hydraulic pump has a large displacement, so the oil tank of the linear winch is required to have a specified minimum volume; 3. The linear winch is a slender strip structure, so the side oil tank can only be made into a slender strip structure; 4. The linear winch is very heavy, the crawler chassis occupies a large height, and the road conditions are generally very flat, and only this part of the irregular space can be used. For this reason, many linear winches have part of the structure of the oil tank sunk between the crossbeams of the crawler chassis. This change is equivalent to thickening the oil tank partition, which is not a problem, but because the oil pump has a large displacement, the oil tank structure is too slender, and the high oil suction height, the situation is very different, so that the hydraulic pump often fails to pressurize. Utility Model Content

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides a hydraulic oil tank structure for a rope-changing linear winch, which reduces the flow resistance in the tank, solves the problem that the hydraulic pump is not easy to pressurize, and effectively prolongs the service life of the hydraulic pump.

[0006] The utility model is realized through the following technical scheme: a hydraulic oil tank structure of a rope-changing linear winch, comprising a box body, a concave structure is provided at the bottom of the box body, a vertical partition is provided inside the box body, an oil suction filter, an oil return filter and an air filter are provided outside the box body, and a guide plate is provided inside the oil return filter.

[0007] The concave structure is arranged at the middle part of the bottom surface of the box body.

[0008] The concave structure has an arc-shaped guide plate at the upper corner of one side close to the oil return filter, and a downwardly inclined straight guide plate at the upper corner of the other side away from the oil return filter.

[0009] The vertical partition separates the oil suction filter and the oil return filter on both sides. A rectangular hole is provided at the lower corner of the side of the vertical partition away from the oil suction filter and the oil return filter, and a folding plate is provided in the area of ​​the oil return filter to expand its area.

[0010] The guide plate is arranged in the oil return filter box and along the axial direction of the oil return filter, and the tail of the guide plate is cut into an oblique angle.

[0011] The beneficial effects of the utility model are as follows: the residual kinetic energy of the oil in the return oil filter is fully utilized, and the flow resistance of the oil in the box is effectively reduced by arranging the guide plate, thereby greatly improving the oil suction condition of the oil pump, so that the hydraulic pump can be pressurized smoothly without premature damage due to air suction and cavitation.
