TECHNICAL FIELD

[0001] The present application relates to a drag chain guide device, in particular to an arc-shaped drag chain guide device, and belongs to the technical field of drag chains. BACKGROUND

[0002] With the increasing industrialization of China, automatic walking equipment is applied more and more widely, and the use occasions of engineering drag chains also increase. The application of long-distance arc-shaped walking equipment puts forward the use demand for long-distance arc-shaped arrangement of drag chains. However, due to the material, structure and stress of the drag chain itself, the long-distance arc-shaped drag chain is prone to "deviation" and "stagnation" during use, which greatly reduces the service life of the drag chain and even affects the normal operation of the equipment. People have designed a ring-shaped rotating guide groove structure for the arc-shaped drag chain. The basic principle is to set the moving end guide groove of the drag chain as a structure that can rotate with the moving end of the drag chain, thereby reducing the friction between the drag chain and the guide groove, and making the guide groove and the moving end of the drag chain relatively static and move together. However, this structure is only suitable for small size and small radius of rotation of the drag chain arrangement method. For long-distance arc-shaped drag chains with a radius of rotation of more than 10 meters, a super large movable guide groove needs to be made, which has high manufacturing and processing cost and is difficult to install.

[0003] Therefore, it is urgent to design an arc-shaped drag chain guide device with simple structure, low manufacturing cost and easy installation to solve the above application problems. SUMMARY

[0004] In view of the above facts, the present application designs an arc-shaped drag chain guide device which can realize the guiding effect of the long-distance arc-shaped drag chain inside and outside the arc segment.
