Technical Field
[0001] This utility model relates to the field of wheel stoppers, specifically a wheel stopper for endless rope winches. Background Technology
[0002] Car stoppers, also known as parking devices, are an important facility in coal mine transportation systems. They are runaway prevention devices, typically installed at the top of a slope. They restrict mine cars to a designated position and prevent runaway accidents. They are often used in conjunction with pushers, tippers, car climbers, cages, and winches. While car stoppers come in various shapes, their structure and working principle are basically the same. Furthermore, the requirements for car stoppers are becoming increasingly stringent. The main disadvantages of manual car stoppers include low safety performance, inability to achieve remote control, inflexible operation, laborious operation, and unsightly appearance. Pneumatic car stoppers have largely solved these problems, and there is a growing trend of pneumatic car stoppers gradually replacing manual ones.
[0003] Please refer to the patent announcement CN216943098U, which discloses a special car stop for an endless rope winch in a coal mine. That patent describes a car stop located between and below two rails, comprising two parallel and spaced-apart plates with a rotatable car-stopping block between them; a first side plate connecting the two plates; and a second side plate connecting the two rails below them; the first and second side plates being opposite each other, with a limiting mechanism between them; the limiting mechanism including a protrusion on the first side plate with its axis parallel to the rails; and a groove on the second side plate; the groove being divided into a horizontal groove and a vertical groove, with multiple parallel horizontal grooves perpendicularly intersecting the vertical groove. However, the limiting structure of this device is relatively simple, making it inconvenient to quickly limit the movement of the slide rails, resulting in low flexibility and practicality. Therefore, this application proposes another technical solution to address this problem. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a special brake for endless rope winches, which has the advantages of high stability and rapid braking. It solves the problems of the simple limiting structure of the reference patent, which is inconvenient for quickly limiting the slide rail and has low flexibility and practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a special wheel stop for endless rope winches, including a slide rail frame, wherein an adjustment and limiting mechanism is provided on the outer side of the slide rail frame;
[0006] The adjustment and limiting mechanism includes a storage frame fixedly installed on the front of the slide rail frame. Two protective covers are fixedly installed on the inner side of the slide rail frame. The inside of the protective cover is rotatably connected to a moving wheel. The outside of the moving wheel is slidably connected to the slide rail body. Adjustment boxes are fixedly installed on the left and right sides of the slide rail frame.
[0007] A brake motor is fixedly installed on the outside of the regulating box. A bidirectional lead screw that is rotatably connected to the regulating box is fixedly installed on the output shaft of the brake motor. Two threaded blocks are threadedly connected to the outside of the bidirectional lead screw, and a limit component is provided at the bottom of the threaded blocks.
[0008] Furthermore, the limiting component includes a limiting rod that is fixedly installed on one side of the threaded block and slidably connected to the adjusting box, a mounting base that is fixedly installed on one side of the limiting rod, a friction pad that is fixedly installed on one side of the mounting base, and a fixing groove corresponding to the friction pad that is opened on the outer side of the slide rail body.
[0009] Furthermore, a through groove is provided on the inner side of the protective cover, and the movable wheel is rotatably connected to the protective cover through the through groove.

[0013] Furthermore, a limiting groove is provided at the bottom of the regulating box, and the limiting rod is slidably connected to the regulating box through the limiting groove.
[0014] Furthermore, the friction pad is made of rubber.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] This special wheel stopper for endless rope winches, through its adjustable limit mechanism, uses a brake motor and a two-way lead screw to drive two threaded blocks to move closer or further apart under the limit of the limit rod. This, in turn, moves the mounting base and friction pad until they fit and fix against the limit groove on the outer side of the slide rail body, facilitating rapid wheel stop movements. Alternatively, it can drive the two threaded blocks to move further apart, so that the friction pad no longer clamps and fixes the slide rail body, greatly improving the flexibility and practicality of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 The wheel stopper for a continuous rope winch in this embodiment includes a slide rail frame 1, and an adjustment and limiting mechanism is provided on the outer side of the slide rail frame 1.
[0024] In the first embodiment, the adjusting limit mechanism includes a storage frame 2 fixedly installed on the front of the slide rail frame 1. Two protective covers 3 are fixedly installed on the inner side of the slide rail frame 1. The inner side of the protective cover 3 is rotatably connected to a movable wheel 4. A through groove is opened on the inner side of the protective cover 3. The movable wheel 4 is rotatably connected to the protective cover 3 through the through groove, which helps to protect the movable wheel 4 by using the protective cover 3.
[0025] The movable wheel 4 is slidably connected to the slide rail body 5 on its outer side. The top of the slide rail body 5 is provided with a slide groove. The movable wheel 4 is movably connected to the slide rail body 5 through the slide groove, which facilitates the movement of the movable wheel 4 on the top of the slide rail body 5. Adjustment boxes 6 are fixedly installed on the left and right sides of the slide rail frame 1, which facilitates the use of two adjustment boxes 6 to fix the slide rail body 5.
[0026] In this embodiment, a brake motor 7 is fixedly installed on the outside of the regulating box 6, which facilitates the installation and fixation of the brake motor 7. The output shaft of the brake motor 7 is fixedly installed with a bidirectional lead screw 8 that is rotatably connected to the regulating box 6. A movable groove is provided on one side of the regulating box 6, and the bidirectional lead screw 8 is rotatably connected to the regulating box 6 through the movable rod groove, which helps the brake motor 7 drive the bidirectional lead screw 8 to rotate.
[0027] In embodiment 2, two threaded blocks 9 are threadedly connected to the outer side of the bidirectional lead screw 8. The outer side of the bidirectional lead screw 8 has two threaded grooves with opposite directions. The threaded blocks 9 are threadedly connected to the bidirectional lead screw 8 through the threaded grooves, which facilitates the movement of the threaded blocks 9 on the bidirectional lead screw 8. A limit component is provided at the bottom of the threaded blocks 9. The limit component includes a limit rod 10 that is fixedly installed on one side of the threaded blocks 9 and slidably connected to the adjustment box 6.
[0028] The bottom of the regulating box 6 has a limiting groove, and the limiting rod 10 is slidably connected to the regulating box 6 through the limiting groove, which facilitates the limiting of the limiting rod 10. A mounting base 11 is fixedly installed on one side of the limiting rod 10, and a friction pad 12 is fixedly installed on one side of the mounting base 11. The friction pad 12 is made of rubber, which helps to increase the friction of the fixation. A fixing groove 101 corresponding to the friction pad 12 is opened on the outer side of the slide rail body 5, which facilitates the movement of the friction pad 12 into the interior of the fixing groove 101, which facilitates the limiting.
[0029] It should be noted that this special wheel stopper for endless rope winches, through the setting of the adjustment limit mechanism, uses the action of the brake motor 7 and the bidirectional lead screw 8 to drive the two threaded blocks 9 to move closer or further apart under the limit of the limit rod 10. This drives the mounting base 11 and the friction pad 12 to move until they fit and fix to the fixing groove 101 on the outside of the slide rail body 5, facilitating rapid wheel stop activities. Alternatively, it can drive the two threaded blocks 9 to move further apart, so that the friction pad 12 no longer clamps and fixes the slide rail body 5, greatly improving the flexibility and practicality of the device.
[0030] The working principle of the above embodiments is as follows:
[0031] This endless rope winch special car stopper can first place the goods inside the storage frame 2 when in use. The entire device can be moved on the top of the slide rail body 5 by the slide rail frame 1 and the moving wheel 4. When it is necessary to stop the device during the movement, the two brake motors 7 located outside the adjustment box 6 can be activated. The brake motors 7 drive the bidirectional lead screw 8 to rotate. The two threaded blocks 9 outside the bidirectional lead screw 8 begin to move closer or further away from each other under the limit of the limit rod 10. The movement of the limit rod 10 drives the mounting base 11 and the friction pad 12 to move.
[0032] Furthermore, once the friction pad 12 is fitted and fixed to the fixing groove 101 on the outside of the slide rail body 5, the friction pad 12 can limit and fix the slide rail body 5, thus stopping the vehicle. Similarly, the brake motor 7 can be started to rotate in the opposite direction. The brake motor 7 drives the bidirectional lead screw 8 to rotate in the opposite direction, thereby driving the two threaded blocks 9 to move away from each other, so that the friction pad 12 no longer clamps and fixes the slide rail body 5, greatly improving the flexibility and practicality of the device.
