Its purpose is to ensure that the wire rope has a good lubrication effect during operation, thereby extending its service life, reducing wear, reducing energy consumption, and improving safety. As a common lifting equipment in construction, tower cranes are widely used in the construction of high-rise buildings and material handling.

[0003] Existing technologies, such as the utility model patent with publication number CN223063634U, disclose a tower crane wire rope lubrication device. This patent includes a lubrication device housing, comprising an upper housing and a lower housing. An oil outlet is fixedly installed at the center of the bottom of the lower housing, and a grid is installed inside the lower housing. The upper and lower housings are fixedly connected by bolts and latches. This tower crane wire rope lubrication device, in order to better spray lubricating oil onto the wire rope and achieve recycling, incorporates an oil outlet, grid, oil baffle, wire rope, oil storage tank, oil filling port, oil recovery port, oil drain port, oil level observation port, oil pump, heater, high-pressure oil pipe interface, first high-pressure oil pipe, second high-pressure oil pipe, first oil nozzle, and second oil nozzle. It can spray lubricating oil onto the wire rope and is equipped with an oil collection device, along with oil pipes, filters, an oil collection tank, and a oil recovery pipe, thereby enabling recycling.

[0004] During the construction of high-rise buildings, it was found that when operating tower crane equipment, the steel wire rope of the tower crane winch is subjected to extremely high tension and friction. This leads to an increase in friction between the steel wire rope and the tower crane pulley, which easily causes wear on the surface of the steel wire rope, thereby reducing the service life of the steel wire rope and causing it to break.

[0005] This application provides a technical solution to the technical problem, aiming to provide those skilled in the art with a variety of solutions to the problem. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the existing technology that, during the operation of tower crane equipment, the steel wire rope of the tower crane winch is subjected to extremely high tension and friction. At this time, the friction between the steel wire rope and the tower crane pulley will continuously increase, which will easily lead to wear on the surface of the steel wire rope, thereby reducing the service life of the steel wire rope and causing the steel wire rope to break.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a winch body and an auxiliary device. A roller frame is mounted on the surface of the winch body. A wire rope body is arranged on the inner arc surface of the roller frame. A hook is provided at one end of the wire rope body. An electrical control cabinet is mounted on one side of the surface of the winch body. Adjustment devices are provided on both sides of the roller frame corresponding to the positions of the wire rope body. The adjustment device includes an adjustment frame and a support frame.

A servo motor is fixedly connected to one side of the adjustment frame. The output end of the servo motor is fixedly connected to one end of the drive rod. Movable plates are fixedly connected to both sides of the bottom end of the support frame. The surface of the movable plate is threaded through the arc surface of the drive rod. Both sides of the lower surface of the support frame are fixedly connected to infusion tubes. The bottom ends of the two infusion tubes are fixedly connected to the same through frame. The lower surface of the through frame is fixedly connected to several nylon columns. The surface of the columns abuts against the surface of the wire rope body. An installation ring is fixedly connected to the upper surface of one end of the adjusting frame. A lubrication cylinder is fixedly connected to the inner wall of the installation ring with the aid of an auxiliary device. A connecting pipe, which is a plastic hose, is fixedly connected to the bottom end of the lubrication cylinder. One end of the connecting pipe slides through one side of the inner wall of the support frame. A movable frame is fixedly connected to the side wall of the support frame.

The cross-section of the movable frame is "L" shaped. The upper end of the movable frame slides through the arc surface of the installation ring.

[0008] The effect achieved by the above components is as follows: During high-altitude operations of tower crane equipment, in order to lubricate and protect the surface of the wire rope body in the winch body, the adjustment device set on both ends of the roller frame can be used for auxiliary operation. The bearing frame drives the through frame to move in position, so that the lubricant in the bearing frame can be adsorbed by the hair column on the lower surface of the through frame, and at the same time, the hair column can be used to lubricate the surface of the wire rope body.

[0009] Preferably, a limiting rod is fixedly connected to the bottom of the inner wall of the adjusting frame, and the arc surface of the limiting rod slides through the surface of the moving plate.

[0010] The aforementioned components achieve the following effect: when the position of the load-bearing frame is moved horizontally by means of the moving plate, the limiting rod can be used for auxiliary guidance and protection.

[0011] Preferably, a compression block is fixedly connected to one side of the upper end of the movable frame. The compression block is a rubber block, and the surface of the compression block abuts against one side of the arc surface of the lubrication cylinder.

[0012] The effect achieved by the above-mentioned components is that when the lubrication cylinder is squeezed by the rubber extrusion block, it can provide effective protection and avoid excessive extrusion damage to the lubrication cylinder.

[0013] Preferably, the bottom cross-section of the inner wall of the support frame is conical, and the cross-sectional dimensions of the inner wall of the support frame are adapted to the cross-sectional dimensions of the infusion tube.

[0014] The effect achieved by the above components is that the bearing frame with a pointed conical cross-section of the inner wall can quickly divert the lubricating fluid, making it easier for the lubricating fluid to flow into the infusion tube.

[0015] Preferably, an auxiliary device is provided on the arc surface of the mounting ring corresponding to the position of the lubrication cylinder. The auxiliary device includes an insert groove, which is formed on the arc surface of the mounting ring. A connecting block is fixedly connected to one side of the arc surface of the lubrication cylinder. The surface of the connecting block is inserted into the inner wall of the insert groove. A positioning frame is fixedly connected to the surface of the mounting ring corresponding to the position of the insert groove. A rotating plate is rotatably connected to the inner wall of the positioning frame. A sliding frame is slidably connected to the rotating plate. Positioning rods are fixedly connected to the lower surfaces of both sides of the sliding frame. A connecting plate is fixedly connected to the surface of the connecting block. The connecting plate has a U-shaped cross-section. The inner wall of the connecting plate is inserted into the surface of the rotating plate. Positioning holes are formed on both sides of the surface of the connecting plate. The inner walls of the positioning holes are inserted into the arc surface of the positioning rods.

[0016] The effect achieved by the above components is that when the lubricating fluid is output using the lubricating cylinder set on the upper surface of the adjusting frame, the auxiliary device set on the surface of the mounting ring can be used for operation. The docking limit between the connecting plate and the rotating plate helps to facilitate the convenient and effective replacement and installation of the entire lubricating cylinder.

[0017] Preferably, both ends of the inner wall of the positioning frame are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the positioning frame and the rotating plate, respectively.

[0018] The effect achieved by the above components is that the torsional force generated by the coil spring can fix and limit the position of the rotating plate, which helps to protect the position of the rotating plate.

[0019] Preferably, the rotating plate has a long strip-shaped cross-section, the rotating plate is a hard alloy plate, and the cross-sectional dimensions of the rotating plate are adapted to the inner wall cross-sectional dimensions of the connecting plate.

[0020] The effect achieved by the above-mentioned components is that when the rotating plate and the inner wall of the connecting plate are locked together, the rotating plate made of hard alloy material can be used to assist in avoiding deformation.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, the operation of the adjustment device achieves the rotation of the drive rod, which in turn drives the entire bearing frame to move horizontally along the roller frame. At the same time, the bob provided at the bottom of the bearing frame uses the lubricating fluid in the lubrication cylinder to lubricate and protect the surface of the wire rope body, which helps to protect the wire rope body after long-term operation.

[0023] In this invention, the position of the lubricating cylinder is fixed and limited by the operation of the auxiliary device. The mounting ring can be connected to the connecting block fixed on the surface of the lubricating cylinder by means of the inlay groove on the surface of the mounting ring. At the same time, the connecting plate on the surface of the connecting block can be engaged with the rotating plate on the surface of the mounting ring, thereby fixing the position between the entire lubricating cylinder and the mounting ring, which helps to limit the replacement operation of the entire lubricating cylinder.
