[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a tightening device for a chain used for lifting and fixing large equipment. Figure 1-3 , a tightening device for a chain used for lifting and fixing large equipment comprises a mounting frame 1, a winding roller 2 is mounted on the mounting frame 1, and a driving motor is also mounted on one side of the winding roller 2 for driving the winding roller 2 to rotate, which is a commonly used technical means for tightening the chain in this field, one side of the mounting frame 1 is rotatably connected to a No. 1 threaded rod 4, the No. 1 threaded rod 4 is threadedly connected to a moving frame 5, both sides of the moving frame 5 are rotatably connected to a No. 2 threaded rod 6, and the No. 2 threaded rod 6 is threadedly connected to a moving block 8, and correspondingly, a component for limiting the moving block 8 can also be installed on the moving block 8, such as installing a limiting sliding rod that runs through the moving block 8, so that the moving block 8 can maintain stable movement when driven by the No. 2 threaded rod 6 and does not rotate with the No. 2 threaded rod 6, which is a technical means well known in the art, so it will not be described in detail;

[0022] One side of the moving block 8 is fixedly connected to the support plate 9, one side of the support plate 9 is fixedly connected to the spring 10, and one side of the spring 10 is fixedly connected to the combing plate 11. The spring 10 is used to push the combing plate 11 to clamp the passing chain so that the mutually twisted lock buckles are corrected after being limited.

[0023] By adopting the above technical solution, a cleaning soft brush is installed on the combing plate 11, which can also clean the dust adhering to the lower lock buckle during combing, so that the lock buckle remains clean.

[0024] By adopting the above technical solution, the combing plate 11 is fixedly connected to the limiting rod 12 near the middle of one side of the spring 10 on the same side, and the limiting rod 12 is slidably connected to the support plate 9. The provided limiting rod 12 is used to limit the combing plate 11 on one side to prevent the combing plate 11 from tilting, and to keep the combing plate 11 able to move back and forth only based on the support plate 9 on the same side, which is convenient for combing and wiping the chain.

[0025] By adopting the above technical solution, the middle part of the upper end of the movable frame 5 is fixedly connected to the oil storage tank 13, a transport pipe is installed on one side of the oil storage tank 13, and one side of the transport pipe is fixedly connected to the mounting frame 14, a sponge 15 is fixedly installed in the mounting frame 14, and the sponge 15 is connected to the transport pipe. When the chain is combed by the combing plate 11 and the lock buckles are corrected, it will pass through the mounting frame 14 and the sponge 15 and contact with the lubricating oil in the sponge 15, so that the surface of the chain is lubricated, reducing the wear of the chain when tightening.

[0026] By adopting the above technical solution, the No. 2 threaded rod 6 is fixedly connected to one side close to each other, and one side of the No. 2 threaded rod 6 is fixedly connected to the turning handle 7. The turning handle 7 can drive the No. 2 threaded rod 6 to rotate, so that the No. 2 threaded rod 6 drives the moving block 8 to move, and drives the two combing plates 11 to adjust the position, so that the position of the combing plate 11 is adjustable, which is suitable for combing and lubricating chains of different sizes.

[0027] By adopting the above technical solution, one side of the No. 1 threaded rod 4 passes through the side wall of the mounting frame 1 and is fixedly connected to the servo motor 3. The servo motor 3 is fixedly connected to the side wall of the mounting frame 1, which can drive the No. 1 threaded rod 4 to rotate, so that the No. 1 threaded rod 4 drives the mobile frame 5 to move, and drives the components on the mobile frame 5 to move.

[0028] The implementation principle of the tightening device for the chain used for hoisting and fixing large equipment in the embodiment of the present application is as follows: when the chain needs to be tightened, the servo motor 3 can be started, so that the servo motor 3 drives the No. 1 threaded rod 4 to rotate, and the No. 1 threaded rod 4 drives the moving frame 5 to move, and drives the combing plate 11 installed on one side of the moving frame 5 to move, and the combing plate 11 drives the clamped chain to move slowly, so that the chain is driven by the winding roller 2 to rotate and reel, and also moves laterally, so that the chain is evenly reeled on the reel 2, and the shape of the combing plate 11 can also be changed, such as the side is set to an arc shape, so that the combing plate 11 can be more convenient to drive the chain to move laterally when it moves laterally;

[0029] When the chain is rolled up using the winding roller 2, the chain can pass between the two combing plates 11. Since the combing plates 11 are pushed by the spring 10, the combing plates 11 limit the chain. The mutually connected lock buckles in the chain are adjusted and rotated after being limited. Figure 4 As shown in the situation shown, the lock buckle is combed when it is about to be rolled up on the winding roller 2 so that it can be rolled up in a close fit after rolling up, preventing the occurrence of vertical protrusions and making the rolling smoother.
