The device for preventing the tail rope of a motorized capstan provided by the utility model is placed at the rear of the motorized capstan, and detects the movement parameters of the tail rope through the speed measuring device. When an abnormal change is detected, the damping device and the braking device automatically lock the tail rope;

[0004] However, the above solution has a complex overall structure, and there may be problems of slipping or being unable to lock the tail rope when locking it. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1 As shown, the tail rope anti-wear device comprises a main board 1, a guide plate 11 is arranged below one side of the main board 1, the main board 1 and the guide plate 11 are an integrated structure and are in an "L" shape, and then, a power connection block 2 and an auxiliary connection block 3 are rotatably arranged on the side of the main board 1 and above the guide plate 11, wherein the power connection block 2 and the auxiliary connection block 3 are arranged in parallel;

[0024] The two ends of the power connection block 2 and the auxiliary connection block 3 are connected by a linkage block 23, and the two ends of the linkage block 23 are rotatably connected to the power connection block 2 and the auxiliary connection block 3 respectively. A joystick 22 is provided at one end of the power connection block 2 close to the linkage block 23, and locking blocks 21 are provided on the sides of the power connection block 2 and the auxiliary connection block 3, and the locking blocks 21 are arc-shaped.

[0025] Reference Figure 2 When the tail rope 4 is in an abnormal working state and emergency braking is required, the operating lever 22 above the operating power connecting block 2 is only needed to be pulled backwards, so that the power connecting block 2 and the locking block 21 on the side can be driven to rotate. At the same time, since the two ends of the power connecting block 2 and the auxiliary connecting block 3 are connected by the linkage block 23 and are arranged in parallel, when the power connecting block 2 rotates, the auxiliary connecting block 3 also rotates, so that the emergency braking of the tail rope 4 of the winch can be realized, thereby ensuring the safe use of the tail rope 4 of the winch; the overall structure is simple, the stability is good, the operation steps are simple, and the tail rope can be locked by only pulling down the operating lever 22, and the locking effect is good.

[0026] Embodiment 2

[0027] Reference Figure 1 , Figure 3 and Figure 4As shown, the tail rope anti-wear device comprises a main board 1, a guide plate 11 is arranged below one side of the main board 1, the main board 1 and the guide plate 11 are an integrated structure and are in an "L" shape, and then, a power connection block 2 and an auxiliary connection block 3 are rotatably arranged on the side of the main board 1 and above the guide plate 11, wherein the power connection block 2 and the auxiliary connection block 3 are arranged in parallel;

[0028] The two ends of the power connection block 2 and the auxiliary connection block 3 are connected by a linkage block 23, and the two ends of the linkage block 23 are rotatably connected with the power connection block 2 and the auxiliary connection block 3 respectively. A return spring 24 is connected between the rotating shafts of the power connection block 2 and the linkage block 23 and the rotating shafts of the auxiliary connection block 3 and the main board 1; when the tail rope 4 is in normal working process, the tail rope 4 passes through between the guide plate 11 and the power connection block 2. At this time, in order to avoid the power connection block 2 and the auxiliary connection block 3 rotating and causing the locking block 21 to contact the tail rope 4 and cause friction, a return spring 24 is provided to connect the rotating shaft of the power connection block 2 and the linkage block 23 and the rotating shaft of the auxiliary connection block 3 and the main board 1. When the power connection block 2 is in a free working state, the upper end of the power connection block 2 can be pulled by the return spring 24, so that the power connection block 2 and the auxiliary connection block 3 can maintain the initial state without easily rotating, effectively avoiding the situation that the tail rope 4 rotates during the working process of the power connection block 2, causing friction between the two locking blocks 21 and the tail rope 4.

[0029] An operating rod 22 is provided at one end of the power connection block 2 close to the linkage block 23 , and locking blocks 21 are provided on the sides of the power connection block 2 and the auxiliary connection block 3 , and the locking blocks 21 are arc-shaped.

[0030] When in use, keep the anti-wear device in the open state, then, pass the tail rope 4 through the guide plate 11 on one side of the main board 1, and when the tail rope 4 passes through the guide plate 11 under the power connecting block 2 and the auxiliary connecting block 3, the guide plate 11 can play a role of stable support for the tail rope 4. When the working state of the tail rope 4 is abnormal and emergency braking is required, it is only necessary to pull the operating lever 22 above the operating power connecting block 2 backwards, so that the power connecting block 2 and the locking block 21 on the side can be driven to rotate. At the same time, since the two ends of the power connecting block 2 and the auxiliary connecting block 3 are connected by the linkage block 23 and are arranged in parallel, when the power connecting block 2 rotates, the auxiliary connecting block 3 also rotates, so that the emergency braking of the tail rope 4 of the winch can be achieved, thereby ensuring the safe use of the tail rope 4 of the winch; the overall structure is simple, the stability is good, the operation steps are simple, and the tail rope can be locked by pulling down the operating lever 22, and the locking effect is good.

[0031] Embodiment 3

[0032] Since the tail rope 4 passes through the top of the guide plate 11 and the bottom of the locking block 21, the locking block 21 is away from the tail rope 4 during the normal operation of the tail rope 4. When the tail rope 4 is in an abnormal working state, it is only necessary to pull the operating lever 22 downward to allow the locking block 21 to press and fix the tail rope 4. However, since the movement speed of the tail rope 4 is relatively fast, when the tail rope 4 is in an abnormal working state, the operating lever 22 needs to be quickly lowered. At this time, since the locking block 21 is squeezed with the tail rope 4, in order to ensure that the tail rope 4 will not deviate or fall off when the locking block 21 presses down on the tail rope 4, a groove specifically for the tail rope 4 to pass through can be opened above the guide plate 11, or the guide plate 11 can be designed to have a "U" cross-section.

[0033] The working principle of this utility model:

[0034] When in use, the anti-wear device will be kept in the open state, and then the tail rope 4 will be passed through the guide plate 11 on one side of the main board 1. When the tail rope 4 passes through the guide plate 11 under the power connecting block 2 and the auxiliary connecting block 3, the guide plate 11 can provide stable support for the tail rope 4. When the working state of the tail rope 4 is abnormal and emergency braking is required, it is only necessary to pull the operating lever 22 above the operating power connecting block 2 backward to drive the power connecting block 2 and the locking block 21 on the side to rotate. At the same time, since the two ends of the power connecting block 2 and the auxiliary connecting block 3 are connected by the linkage block 23 and are arranged in parallel, when the power connecting block 2 rotates, the auxiliary connecting block 3 will rotate, and the emergency braking of the grinding tail rope 4 can be achieved.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
