Technical Field
[0001] The utility model belongs to the technical field of drag chain protection, and particularly relates to a drag chain protection device for vertical direction. Background Technique
[0002] Drag chains are suitable for use in reciprocating motion occasions and can play a role in traction and protection for internal cables, oil pipes, gas pipes, water pipes, etc. They are generally flat and composed of several unit chain links. The chain links can rotate freely, and the unit chain link is composed of two chain plates and upper and lower cover plates. At present, drag chains have been widely used in the fields of numerical control machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, manipulators, lifting and transportation equipment, automated warehouses, etc.
[0003] In the field of industrial transportation, especially in vertical transportation, the drag chain responsible for power has a long stroke from top to bottom. During the transmission process, it often shakes, resulting in problems such as the drag chain breaking away. Content of the Utility Model
[0004] The purpose of the utility model is to provide a drag chain protection device for vertical direction with simple structure and reasonable design in order to solve the above problems.
[0005] The utility model realizes the above purpose through the following technical solutions:
[0006] A drag chain protection device for vertical direction includes multiple groups of fixed brackets and multiple groups of limiting mechanisms. The fixed bracket is a cuboid frame composed of four guide bars, and each adjacent two fixed brackets are connected by a protection mechanism. The protection mechanism includes a mounting frame in a trough-shaped structure, mounting boxes installed at the top and bottom of the mounting frame, and elastic telescopic members installed inside the mounting boxes and inclined near one side of the fixed bracket.
[0007] As a further optimized scheme of the utility model, the limiting mechanism includes a mounting member in a trough-shaped structure, and wear-resistant stop bars in an L-shaped structure installed at the four corners inside the mounting member.
[0008] As a further optimized scheme of the utility model, one side of the mounting frame is detachably installed with a first connecting member, and a plurality of first mounting holes are opened on the first connecting member.
[0009] As a further optimized scheme of the utility model, one side of the mounting member is detachably installed with a second connecting member, and a plurality of second mounting holes are opened on the second connecting member.
[0010] As a further optimized scheme of the utility model, a plurality of fixing holes are opened at the four corners of the mounting frame, and a plurality of connecting holes for cooperating with the fixing holes are opened on the four guide bars.
[0011] As a further optimized solution of the present utility model, a transmission channel facilitating the transmission of the drag chain is formed between the fixed bracket and the mounting bracket.
[0012] The beneficial effects of the present utility model are as follows: When the drag chain runs, the present utility model can play a good limiting and guiding role, and the extended moving protection design enables the drag chain to remain stable during the vertical movement process, preventing the drag chain from swinging rhythmically. At the same time, through the provided inclined elastic telescopic member, the greater the elastic force the drag chain bears when moving outwards, so that there is a buffer space during the transmission process of the drag chain, making it less likely for the drag chain to derail or be damaged.

[0020] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] As Figure 1 - Figure 6As shown in the figure, a drag chain protection device for vertical use includes multiple groups of fixed brackets 1 and multiple groups of limiting mechanisms 2. The fixed bracket 1 is a cuboid frame composed of four guide bars 11. And between every two adjacent fixed brackets 1, they are connected by a protection mechanism 3. The protection mechanism 3 includes a mounting frame 31 with a trough-shaped structure, mounting boxes 32 installed at the top and bottom of the mounting frame 31, and elastic telescopic members 33 installed inside the mounting boxes 32 and inclined near one side of the fixed bracket 1. A transmission channel for the drag chain 4 to drive is formed between the fixed bracket 1 and the mounting frame 31. The drag chain 4 drives up and down in the transmission channel, which plays a good role in restricting and guiding the operation of the drag chain, and the extended moving protection design enables the drag chain 4 to remain stable during the vertical movement process, preventing the drag chain 4 from swinging rhythmically. At the same time, when in use, the drag chain 4 drives up and down in the transmission channel. Through the provided inclined elastic telescopic member 33, the greater the elastic force the drag chain 4 bears outward. In this way, there is a buffer space for the drag chain 4 during the driving process, and it is less likely to derail the drag chain 4 or cause damage to the drag chain 4;
[0022] As Figure 2 shown in the figure, the limiting mechanism 2 includes a mounting member 21 with a trough-shaped structure, and wear-resistant stop strips 22 installed at the four corners inside the mounting member 21 and having an L-shaped structure. By providing the mounting member 21, the drag chain 4 can move inside it, reducing the situation of the drag chain 4 shaking. At the same time, through the provided wear-resistant stop strips 22, the friction generated between the drag chain 4 and the mounting member 21 is reduced, extending the service life of the drag chain 4;
[0023] As Figure 2 and Figure 4 shown in the figure, a first connecting member 34 is detachably installed on one side of the mounting frame 31. Multiple first mounting holes are provided on the first connecting member 34. A second connecting member 23 is detachably installed on one side of the mounting member 21. Multiple second mounting holes are provided on the second connecting member 23. By providing the first connecting member 34 and the second connecting member 23, it is convenient to install the limiting mechanism and the protection mechanism in the place where they need to be used;
[0024] As Figure 6 shown in the figure, multiple fixing holes 35 are provided at the four corners of the mounting frame 31. Multiple connection holes 12 that cooperate with the fixing holes 35 are provided on the four guide bars 11. When installing the mounting frame 31, the mounting frame 3 is sleeved outside the fixed bracket 1 and located at the connection end of two fixed brackets 1, and the locking bolt is screwed into one of the fixing holes 35 and one of the connection holes 12, and the mounting frame 31 is fixed to the guide bar 11.
[0025] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
