Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance auxiliary equipment of chain grates, and in particular relates to a device for quickly replacing chain links of chain grates. Background Art

[0002] Chain grate is a commonly used conveying equipment, widely used in mining, metallurgy, chemical industry and other industries. The chain link of the chain grate is its important component. The wear and damage of the chain link will lead to the decline of the operating efficiency of the chain grate, or even make it unable to work normally. Therefore, it is necessary to replace the damaged chain link of the chain grate.

[0003] At present, the chain link replacement of the chain grate is usually done manually. The operator needs to disconnect the chain, then replace the chain links one by one, and finally dock the chain. This method is cumbersome, time-consuming and labor-intensive, and has certain safety hazards. In addition, since the chain links of the chain grate are usually long, the chain links are prone to fall off during the replacement process, resulting in work interruption. Summary of the invention

[0004] The utility model aims to provide a device for quickly replacing chain links of a chain grate machine to solve the problems existing in the prior art.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a device for quickly replacing chain links of a chain grate machine, comprising a hanging plate, two hanging plates, a bolt bolted between the two hanging plates, a plurality of nuts threaded on the bolts, a plurality of hanging rods welded on the hanging plate, a through hole opened on the hanging plate, any hanging rod on the hanging plate is hung with a wire rope, and the other end of the wire rope is hung with a hook.

[0006] Furthermore, the hanging plate is L-shaped, and the perforations are located at the bottom of the vertical side of the hanging plate.

[0007] Furthermore, the hanging rod is T-shaped, and a plurality of hanging rods are linearly distributed on the horizontal edge of the hanging board.

[0008] Furthermore, the bolt is connected through the vertical edges of the two hanging plates, and there are three nuts, one nut is located at the bolt tail and outside the two hanging plates, and the other two nuts are located between the two hanging plates.

[0009] Furthermore, both ends of the steel wire rope are ring-shaped.

[0010] The utility model has the following beneficial effects:

[0011] 1. The utility model can temporarily connect the chain links of the chain grate, so as to overhaul and replace the chain links between the hanging points, and prevent them from falling off from the chain grate during the overhaul process.

[0012] 2. Two chain links are hooked together and the wire rope is tightened by bolts to temporarily connect the two chain links. The chain links between the two hooks can be disassembled and replaced without the chain links falling off the chain grate.

[0013] 3. The T-shaped hanging rod has the function of preventing the wire rope from falling off and can better hang the wire rope.

[0014] 4. When a shorter wire rope is needed, one end of the wire rope can be passed through the hole of one hanging plate and then hung on the hanging rod of another hanging plate. This can greatly shorten the length of the wire rope without replacing the wire rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Embodiment 1:

[0020] like Figure 1 As shown, a device for quickly replacing chain links of a chain grate machine includes a hanging plate 1, two hanging plates 1, a bolt 2 is bolted between the two hanging plates 1, a plurality of nuts 3 are threaded on the bolt 2, a plurality of hanging rods 4 are welded on the hanging plate 1, a through hole 5 is opened on the hanging plate 1, any hanging rod 4 on the hanging plate 1 is hung with a wire rope 6, and a hook 7 is hung on the other end of the wire rope 6.

[0021] After the two hooks 7 are hung on the two linked shafts, when the nuts 3 are tightened or loosened, the two hanging plates 1 move closer to or farther away from each other, so that the two hung chain links are connected through the utility model, and the chain links between the two hooks 7 can be disassembled and replaced without the chain links falling off the chain grate.

[0022] The hanging plate 1 is L-shaped, and the through hole 5 is located at the bottom of the vertical side of the hanging plate 1. One end of the wire rope 6 is passed through the through hole 5 of one hanging plate 1 and then hung on the hanging rod 4 of another hanging plate 1, so that the length of the wire rope 6 can be greatly shortened, and there is no need to remove the wire rope 6 on the hook 7 and replace it with a wire rope 6 of a suitable length.

[0023] The hanging rod 4 is T-shaped, and a plurality of hanging rods 4 are linearly distributed on the horizontal side of the hanging plate 1. The T-shaped hanging rod 4 has the function of preventing the steel wire rope 6 from falling off, and can better hang the steel wire rope 6.

[0024] The bolt 2 is connected through the vertical edges of the two hanging plates 1 . There are three nuts 3 , one nut 3 is located at the bolt end of the bolt 2 and at the outer sides of the two hanging plates 1 , and the other two nuts 3 are located between the two hanging plates 1 .

[0025] Both ends of the steel wire rope 6 are ring-shaped. This type of steel wire rope 6 is a common type and is often used for lifting.

[0026] Embodiment 2:

[0027] like Figure 2 As shown, this embodiment provides a device for quickly replacing chain links of a chain grate, and the structural structure is basically the same as that of the embodiment 1, except that one end of the steel wire rope 6 passes through the through hole 5 of one hanging plate 1 and is hung on the hanging rod 4 of another hanging plate 1. Compared with the embodiment 1, when a short steel wire rope 6 is needed, the length of the steel wire rope 6 can be greatly shortened in this embodiment, and there is no need to remove the steel wire rope 6 on the hook 7 and replace it with a steel wire rope 6 of a suitable length.

[0028] The working principle of the utility model is:

[0029] When in use, the two hooks 7 are respectively hung on the shafts of the two chain links of the chain grate, and the appropriate hanging rod 4 is selected to hang the wire rope 6 according to the distance between the two chain links, and the nuts 3 on the outside of the two hanging plates 1 are tightened to make the two hanging plates 1 close to each other. At this time, the wire rope 6 is stretched straight, and the nuts 3 between the two hanging plates 1 are tightened to lock the bolts 2. In this way, the chain links between the two hooks 7 can be disassembled and replaced, and the chain links will not fall off from the chain grate. After maintenance, the nuts 3 can be loosened to disassemble the utility model.

[0030] Sometimes, due to the problem of the on-site environment, the distance between the two chain links of the two hooks 7 cannot be too far, and there is no steel wire rope 6 of suitable length at the work site. At this time, one end of the steel wire rope 6 can be passed through the through hole 5 of one hanging plate 1 and then hung on the hanging rod 4 of another hanging plate 1, so that the length of the steel wire rope 6 can be greatly shortened, and there is no need to remove the steel wire rope 6 on the hook 7 and replace it with a steel wire rope 6 of suitable length. At this time, it is necessary to tighten the nut 3 between the two hanging plates 1 first, so that the two hanging plates 1 are separated from each other, and after the steel wire rope 6 is tightened, tighten the other nut 3 to lock the bolt 2, and then disassemble and replace the connection.

[0031] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0032] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
