Description

Technical Field

[0001] The utility model relates to a rope-slip-proof rope-pressing wheel assembly, in particular to a rope-slip-proof rope-pressing wheel assembly, and belongs to the technical field of rope-pressing wheel assemblies. Background Art

[0002] The rope pulley in the winch is an important part of the winch system. Its main function is to ensure that the rope can pass stably and orderly during the operation of the winch and withstand the corresponding tension and friction. The design of the rope pulley usually takes into account factors such as the working environment of the winch, the material and diameter of the rope, and the required tension;

[0003] The rope pulley assembly usually consists of multiple rope pulleys, which are arranged at a certain pitch and angle to form a complete rope channel. Each rope pulley is precisely machined and balanced to ensure that it can run smoothly at high speeds and reduce vibration and noise.

[0004] When the winch is working, the rope is transmitted through the rope pressure wheel group. The design of the rope pressure wheel group allows the rope to maintain proper tension during transmission to prevent the rope from loosening or being overly tight. At the same time, the surface material and structure of the rope pressure wheel are also specially treated to reduce the friction between the rope and the rope pressure wheel, reduce wear and heat generation

[0005] However, when the existing rope-pressing wheel group presses the wire rope, although it can press the moving wire rope to prevent the wire rope from being separated from the wheel group, the rope-pressing wheel group in the existing winch is fixed on a mechanism, and the wheel group formed by multiple pulleys can only limit the wire rope, and the pulley rotates to realize the movement of the wire rope, but the gap size of the existing pulley is fixed, and it can only be adapted to one kind of wire rope. When encountering wire ropes of different thicknesses, in order to ensure a better anti-rope-stripping effect, it is necessary to replace the corresponding pulley, which greatly increases the use cost and reduces the work efficiency.

[0006] Therefore, it is urgent to improve the anti-rope-off pressing wheel group to solve the above-mentioned problems. Utility Model Content

[0009] The pulley mechanism includes a roller rotatably connected to the support frame, a limit plate fixedly connected to one side of the roller surface, a second limit plate slidably connected to the roller, and a fixing mechanism for fixing the second limit plate;

DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figure 1-Figure 4As shown, the rope-slipping-proof pressure pulley assembly provided in this embodiment includes a support frame 1, the support frame 1 includes an L-shaped support plate 11 and a side support rod 12, the two ends of the roller 4 are rotatably connected to the L-shaped support plate 11 and the side support rod 12 respectively, and a mounting hole is provided on the L-shaped support plate 11. The mounting hole can be matched with an external mounting piece to fix the device to the ground or equipment to prevent the device from shaking during use;

[0028] Both sides of the inner wall of the support frame 1 are rotatably connected with pulley mechanisms 2, and a second pulley mechanism 3 with the same structure as the pulley mechanism 2 is slidably arranged between the two pulley mechanisms 2;

[0029] The pulley mechanism 2 includes a roller 4 rotatably connected to the support frame 1, a limit plate 5 fixedly connected to one side of the surface of the roller 4, a second limit plate 6 slidably connected to the roller 4, and a fixing mechanism 7 for fixing the second limit plate 6; wherein a plurality of limit grooves 13 are provided on the surface of the roller 4, and a limit slider 14 slidably connected to the limit groove 13 is provided on the inner wall of the second limit plate 6;

[0030] Further, the fixing mechanism 7 includes a support plate 16 arranged on one side of the outer end surface of the roller 4, a first threaded rod 17 threadedly connected to the support plate 16, and a bearing 18 for connecting the first threaded rod 17 and the second limit plate 6. A limit mechanism 19 is arranged at the outer end of the first threaded rod 17. When the pulley mechanism 2 and the second pulley mechanism 3 need to be adjusted according to the thickness of the wire rope, the first threaded rod 17 is rotated to push the second limit plate 6 to slide on the roller 4, thereby adjusting the gap between the second limit plate 6 and the limit plate 5, so that it can adapt to wire ropes of different diameters;

[0031] Furthermore, the limiting mechanism 19 includes a handle 20 arranged at the outer end of the first threaded rod 17, a limiting rod 21 threadedly connected to the handle 20, and a plurality of limiting holes opened on the support plate 16 and plugged into the limiting rod 21. After the second limiting plate 6 is adjusted according to the thickness of the wire rope, the limiting rod 21 is rotated to connect it with the threaded hole, thereby achieving the fixed adjustment of the first threaded rod 17 to prevent the first threaded rod 17 from rotating during the movement of the pulley in the later stage. It should be noted that since a plurality of limiting holes are provided and the second limiting plate 6 can be adjusted according to the situation, the limiting rod 21 is conveniently inserted into one of the limiting holes;

The locking mechanism 26 includes a fixing frame 28 arranged on the upper back of the support frame 1 and an insertion rod 29 penetrating the fixing frame 28 and the insertion hole 27. After the position of the second pulley mechanism 3 is adjusted by the third threaded rod 25, the insertion rod 29 is inserted into the insertion hole 27 to achieve locking and fixing of the third threaded rod 25 to prevent the third threaded rod 25 from rotating when the wheel group moves later.

[0034] Furthermore, a sliding support frame 22 is provided in the middle part of the outer side of the lower end surface of the L-shaped support plate 11, and a second slider 23 rotatably connected to the second pulley mechanism 3 is slidably provided in the sliding support frame 22, which can support the second pulley mechanism 3 while not affecting the up and down adjustment effect of the second pulley mechanism 3.

[0035] like Figure 1-Figure 4 As shown, the principle of the anti-rope-dropping rope pressure wheel group provided in this embodiment is as follows: when in use, the first threaded rod 17 is rotated to push the second limit plate 6 to slide on the roller 4, so as to adjust the gap between the second limit plate 6 and the limit plate 5, so that it can adapt to steel wire ropes of different diameters, and then adjust the tension of the steel wire rope as needed. When adjusting, the slider 9 is adjusted by rotating the third threaded rod 25, which will drive the second pulley mechanism 3 to adjust the height, thereby realizing the tension adjustment of the steel wire rope.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
