Abstract
Description
Technical Field
[0001] This utility model relates to the field of winch wire rope fixing technology, and in particular to a safety device for fixing winch wire rope with a U-shaped lock. Background Technology
[0002] In the lime production process, the winch is a key piece of equipment for material lifting, and the reliability of its wire rope fixation directly affects production safety.
[0003] In existing technologies, most wire ropes are fixed using pressure plate bolts or wedges. These two fixing methods are mostly designed for single-specification wire ropes. Different pressure plates or wedges are required for different specifications of wire ropes. Moreover, both fixing methods are prone to loosening under high-frequency vibration, which can lead to wire rope slippage. Utility Model Content
[0004] To address the shortcomings or defects of the existing technology, this utility model provides a safety device for fixing wire ropes in winches using a U-shaped lock. The upper and lower bushings can be used to position and clamp wire ropes of different specifications, while the locking block limits the two nuts, thereby enabling more stable fixing of the wire rope during the winding and unwinding process.
[0005] The technical solution is as follows: A safety device for fixing a wire rope in a winch includes a winch on which a wire rope is wound. One end of the wire rope passes through the winch. A U-bolt is slidably connected to the winch. An upper bushing is fixedly connected to the U-bolt, and a lower bushing is fixedly connected to the winch. One end of the wire rope is located between the upper and lower bushings. Nuts are threaded to both ends of the U-bolt opening. Both nuts have grooves. Washers are fitted onto the U-bolt and are located between the two nuts and the winch. A fixing mechanism is provided on the winch.
[0006] Optionally, the upper bushing has a positioning groove.
[0007] Optionally, a limiting groove is provided on the lower bushing.
[0008] Optionally, the fixing mechanism includes a base, which is fixedly connected to the winch. A locking block is slidably connected to the base. The two sides of one end of the locking block are respectively located in the slots on the two nuts. The locking block has an insertion hole. A pin is slidably connected to the base. The bottom of the pin is located in the insertion hole on the locking block. A spring is connected between the base and the pin.
[0009] Optionally, the spring is fitted onto the pin.
[0010] The beneficial effects of this utility model are as follows: the operator rotates the two nuts with a tool, so that the upper bushing and the lower bushing together position and clamp the wire rope. After tightening the two nuts, the locking block is moved so that the locking block limits the two nuts. At the same time, the bottom end of the pin will be inserted into the insertion hole on the locking block. In this way, the upper bushing and the lower bushing can position and clamp wire ropes of different specifications. At the same time, the locking block limits the two nuts, so that the wire rope can be more stably fixed during the winding and unwinding process. Attached Figure Description

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0018] Example 1
[0019] A safety device for securing wire ropes in winches, such as... Figures 1-5 As shown, the device includes a winch 1, on which a wire rope 2 is wound. One end of the wire rope 2 passes through the winch 1. A U-bolt 3 is slidably connected to the winch 1. An upper bushing 4 is welded to the U-bolt 3, and a lower bushing 5 is welded to the winch 1. One end of the wire rope 2 is located between the upper bushing 4 and the lower bushing 5. Nuts 6 are threaded to both ends of the opening of the U-bolt 3. Both nuts 6 have grooves. Washers 7 are fitted onto the U-bolt 3. The washers 7 are located between the two nuts 6 and the winch 1. The winch 1 is equipped with a fixing mechanism.
[0020] The upper bushing 4 has a positioning groove.
[0021] The lower bushing 5 has a limit groove.
[0022] The fixing mechanism includes a base 81, which is welded to the winch 1. A locking block 82 is slidably connected to the base 81. The two sides of one end of the locking block 82 are respectively located in the slots on the two nuts 6. The locking block 82 has an insertion hole. A pin 83 is slidably connected to the base 81. The bottom of the pin is located in the insertion hole on the locking block 82. A spring 84 is connected between the base 81 and the pin 83 by a hook. The spring 84 is sleeved on the pin 83.
[0023] Initially, the locking block 82 presses against the pin 83, compressing the spring 84. First, the worker passes one end of the wire rope 2 through the winch 1, positioning it between the upper bushing 4 and the lower bushing 5. Then, the worker uses a tool to rotate the two nuts 6. The rotation of the two nuts 6 together moves the U-bolt 3 via its threads. The movement of the U-bolt 3 moves the upper bushing 4 closer to the lower bushing 5, allowing the upper bushing 4 and lower bushing 5 to jointly position and clamp the wire rope 2. After tightening the two nuts 6, the locking block is moved... Block 82 allows one end of the locking block 82 to engage in the slots on the two nuts 6. When the locking block 82 moves to the designated position, it no longer presses against the pin 83, and the spring 84 will rebound. The rebound of the spring 84 will drive the pin 83 to move, so that the bottom end of the pin 83 engages in the insertion hole on the locking block 82. In this way, the upper bushing 4 and the lower bushing 5 can be used to position and clamp steel wire ropes 2 of different specifications. At the same time, the locking block 82 limits the two nuts 6, so that the steel wire rope 2 can be fixed more stably during the winding and unwinding process.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
