Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction machine structure, and in particular to a rope-changing traction machine. Background Technology
[0002] In coal mines, steel wire ropes are used extensively. To ensure their strength and prevent production accidents, they often need to be replaced frequently. Traditionally, this is done using a winding machine in conjunction with a traction machine. However, traditional traction machines sometimes result in excessively slack steel wire ropes during traction. This can cause the rope to slack and not move along the pre-planned path, rubbing against various limit structures, or even getting stuck due to accidental entanglement. To address this problem, this application proposes a solution. Summary of the Invention
[0003] Purpose of the utility model: The purpose of this utility model is to provide a rope changing traction machine that, while satisfying the traction of the wire rope, ensures that the wire rope remains taut during the traction process, preventing production safety accidents caused by excessive slack.
[0004] Technical solution: The present invention provides a rope changing traction machine, which includes support plates facing each other on a base plate. Each end face of the opposing support plates is provided with a traction component for traction of a steel wire rope. The rope inlet of the traction component is provided with a three-wheel tensioning device for tensioning the steel wire rope, and the rope inlet of the three-wheel tensioning device is provided with a steering wheel group.
[0005] By installing a three-wheel tensioning device at the rope inlet of the traction assembly, the wire rope entering the traction assembly is tensioned, ensuring that the wire rope remains taut during the traction process.
[0006] Preferably, the traction assembly includes an upper drive sprocket, a lower drive sprocket, and a drive chain. An upper drive sprocket is provided on each of the upper two sides of the support plate end face, and a drive chain is connected between the upper drive sprockets. A channel for the passage of a wire rope is reserved between the upper drive chain formed by the upper drive sprocket and the drive chain formed by the lower drive sprocket and the drive chain.
[0007] The traction assembly completes the traction function of the wire rope.
[0008] Preferably, both the upper and lower drive sprockets are connected to hydraulic cylinders via shafts.
[0009] The hydraulic cylinder provides power to the traction assembly.
[0010] Preferably, the three-wheel tension device includes an inlet fixed wheel, a tension wheel, an outlet fixed wheel, and a bracket. The inlet fixed wheel, tension wheel, and outlet fixed wheel are sequentially arranged on the bracket along the direction in which the wire rope enters the traction assembly. The inlet fixed wheel and the outlet fixed wheel are set at the same height. The bottom of the tension wheel is higher than the height of the line connecting the axes of the inlet fixed wheel and the outlet fixed wheel and lower than the height of the line connecting the tops of the inlet fixed wheel and the outlet fixed wheel.
[0011] The wire rope enters from the inlet fixed pulley and extends from the outlet fixed pulley. The bottom of the tension pulley presses on the wire rope to complete the tensioning of the wire rope.
[0012] Preferably, the tension wheel is mounted on the bracket via a tension shaft, and the tension shaft is mounted on the bracket with adjustable height.
[0013] The adjustable height of the tension shaft allows for adjustment of the height of the tension wheel, thereby adjusting the length of the wire rope pressed down by the tension wheel and thus adjusting the tension of the wire rope.
[0014] Preferably, the steering wheel assembly includes a steering wheel and an extension frame. One end of the extension frame is rotatably connected to the base plate, and the other end is provided with a steering wheel. The steering wheel, the three-wheel tension device, and the traction assembly are located on the same axis.
[0015] The steering wheel completes the introduction of the wire rope, leading it to the three-wheel tension device. The rotatable extension frame allows the steering wheel assembly to retract the extension frame steering support plate when the traction machine is not in operation, reducing the footprint of the traction machine and improving space utilization.
[0016] Preferably, the system also includes a grid-shaped guide roller, which comprises two sets of mutually perpendicular guide rollers. The two sets of mutually perpendicular guide rollers form a wire rope channel in the middle, and the wire rope channel corresponds to the rope inlet and rope outlet of the traction assembly.
[0017] The grid-shaped guide rollers are designed to guide the wire ropes entering and leaving the traction assembly.
[0018] Beneficial effects: Compared with the prior art, this utility model has the following advantages:
[0019] This application ensures that the wire rope remains taut during traction by setting up a three-wheel tension device. Two sets of traction components are set on the opposing support plates to simultaneously traction two wire ropes, improving traction efficiency. At the same time, the rotating extension frame ensures that the extension frame can be rotated to the support plate when the traction machine is not in operation, reducing the footprint of the traction machine and improving space utilization.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0027] See appendix Figures 1-5 The rope-changing traction machine shown in the figure includes support plates 2 facing each other on the base plate 1. Each end face of the opposing support plates 2 is provided with a traction component 3 for traction of steel wire rope. A three-wheel tension device 4 for tensioning the steel wire rope is provided at the rope inlet of the traction component 3. A steering wheel group 5 is provided at the rope inlet of the three-wheel tension device 4. By providing the three-wheel tension device 4 at the rope inlet of the traction component 3, the steel wire rope entering the traction component 3 is tensioned, ensuring that the steel wire rope remains taut during the traction process.
[0028] In this embodiment, the traction assembly 3 includes an upper drive sprocket 31, a lower drive sprocket 32, and a drive chain 33. An upper drive sprocket 31 is provided on each of the upper two sides of the support plate 2 end face, and a drive chain 33 connects the upper drive sprockets 31. A lower drive sprocket 32 is provided on each of the lower two sides of the support plate 2 end face, and a drive chain 33 connects the lower drive sprockets 32. A channel 34 is reserved between the upper drive chain formed by the upper drive sprocket 31 and the drive chain 33, and between the lower drive chain formed by the lower drive sprocket 32 and the drive chain 33, for the passage of a wire rope. The traction assembly 3 completes the traction function of the wire rope.
[0029] In this embodiment, both the upper drive sprocket 31 and the lower drive sprocket 32 are connected to a hydraulic cylinder 35 via a shaft, and the hydraulic cylinder 35 provides power to the traction assembly 3.
[0030] In this embodiment, the three-wheel tensioning device 4 includes an inlet fixed wheel 41, a tension wheel 42, an outlet fixed wheel 43, and a bracket 44. The inlet fixed wheel 41, the tension wheel 42, and the outlet fixed wheel 43 are sequentially arranged on the bracket 44 along the direction in which the wire rope enters the traction assembly 3. The inlet fixed wheel 41 and the outlet fixed wheel 43 are set at the same height. The bottom of the tension wheel 42 is higher than the height of the line connecting the axes of the inlet fixed wheel 41 and the outlet fixed wheel 43 and lower than the height of the line connecting the tops of the inlet fixed wheel 41 and the outlet fixed wheel 43. The wire rope enters from the inlet fixed wheel 41 and extends from the outlet fixed wheel 43. The bottom of the tension wheel 42 presses on the wire rope to complete the tensioning of the wire rope.
[0031] In this embodiment, the tension wheel 42 is mounted on the bracket 44 via the tension shaft 45. The tension shaft 45 is mounted on the bracket 44 with an adjustable height. By adjusting the height of the tension shaft 45, the length of the wire rope pressed down by the tension wheel 42 can be adjusted, thereby achieving the adjustment of the tension of the wire rope.
[0032] In this embodiment, the steering wheel assembly 5 includes a steering wheel 51 and an extension frame 52. One end of the extension frame 52 is rotatably connected to the base plate 1, and the other end is provided with the steering wheel 51. The steering wheel 51 is located on the same axis as the three-wheel tension device 4 and the traction assembly 3. The introduction of the wire rope is completed through the steering wheel 51, and the wire rope is guided to the three-wheel tension device 4. The rotatable extension frame 52 allows the steering wheel assembly 5 to turn the extension frame 52 and store the support plate 2 when the traction machine is not working, thereby reducing the footprint of the traction machine and improving the space utilization rate.
[0033] In this embodiment, a grid guide roller 6 is also provided. The grid guide roller 6 includes two sets of mutually perpendicular guide rollers 61. The two sets of mutually perpendicular guide rollers 61 form a wire rope channel in the middle. The wire rope channel corresponds to the rope inlet and rope outlet of the traction component 3, thereby realizing the guiding function of the wire rope entering the traction component 3 and leaving the traction component 3.
