[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0017] Referring to Figure 1 and Figure 2 As shown in the drawings, the utility model provides an embodiment: a movable drag chain support frame, including three drag chain guide discs 6, adjacent drag chain guide discs 6 are all connected with support bridge frames 2, wherein the left side end upper position of the support bridge frame 2 located at the leftmost side is detachably installed with a support arm 5, the support arm 5 is fixed with the support bridge frame 2, and the top end of the support arm 5 is rotatably connected with a back -pushing wheel 4, the middle position of the support bridge frame 2 is connected with a plurality of parallel arrangement's unpowered idler 3 through the pivot, the upper edge of the unpowered idler 3 is flush with the upper surface of the support bridge frame 2, the surface of the three drag chain guide discs 6 carries a drag chain 1, and the lower edge of the upper half of the drag chain 1 contacts the unpowered idler 3;

[0018] In the prior art, when the drag chain 1 moves, one end moves and the other end is fixed, and a bending part of the drag chain is generated, so that the bending end of the drag chain fixed at one end is in contact with the inner circle wheel of the drag chain guide disc as a whole, the rotation speed of the inner circle wheel is consistent with the linear speed of the drag chain, but the inner circle wheel and the outer circle wheel of the existing drag chain guide disc are integrated, so that the linear speed of the inner circle wheel is consistent with the speed of the drag chain, but the speed of the outer edge of the outer circle wheel of the drag chain guide disc is greater than the linear speed of the inner edge of the inner circle wheel, there is a speed difference, and a speed difference frictional resistance is generated on the upper part of the moving drag chain, which will damage the drag chain and affect the movement efficiency in the long run.

[0019] As Figure 3 The drag chain guide disc 6 of the application includes an inner wheel 602, a roller shaft 603 and an outer wheel 601, the outer wheel 601 is nested on the roller shaft 603 using a bearing, the inner wheel 602 is also nested on the roller shaft 603 using a bearing, the outer wheel 601 includes two annular baffles, the two annular baffles are coaxial with the inner wheel 602, and the two annular baffles are located on the front and rear sides of the inner wheel 602, the end of the roller shaft 603 is rotatably connected with the end of the support bridge frame 2 through a bearing, the inner edge of the drag chain 1 is attached to the inner wheel 602, and the inner wheel 602 can rotate following the movement of the drag chain 1.

[0020] As Figure 4As shown, one end of the drag chain 1 is connected to the fixed equipment, and the other end is connected to the mobile working component, so the lower end of the drag chain 1 is the fixed end 101, and the upper end of the drag chain 1 is the mobile end 103. When the working component operates to the right, that is, the mobile end 103 of the drag chain 1 moves to the right, the bending part 102 also moves to the right, and the inner edge of the bending part 102 is attached to the surface of the inner wheel 602 located at the leftmost side. The bending part 102 drives the inner wheel 602 to rotate clockwise while pushing the inner wheel 602 to move to the right, and because the inner wheel 602 and the outer wheel 601 are coaxial, the outer wheel 601 will also be affected by the right displacement of the bending part 102 and will drive the entire support component to move to the right.

[0021] When the bending part 102 of the drag chain 1 moves to the left, the bending part 102 moves to the left, and the outer surface of the bending part 102 contacts the push wheel 4, which drives the push wheel 4 to move to the left, thereby driving the entire support component to move to the left, and the outer wheel 601 rotates counterclockwise.

[0022] In this application, the drag chain guide disc 6 is divided into an inner wheel 602 and an outer wheel 601 that rotate independently. When the drag chain 1 moves, the speed difference between the rotation of the inner wheel 602 and the outer wheel 601 compensates for the relative displacement between the moving end surface of the drag chain and the drag chain guide disc 6. Specifically, when the mobile end 103 of the drag chain 1 moves left and right, the inner wheel 602 rotates, but the bending part 102 of the drag chain 1 also moves left and right linearly. When it moves to the right, the power comes from the inner edge of the bending part 102 of the drag chain 1 abutting against the surface of the inner wheel 602, which pushes the inner wheel 602 to the right. Because the inner wheel 602 and the outer wheel 601 are coaxial but are connected to the roller shaft 603 through separate bearings, when the inner wheel 602 is abutted, the outer wheel 601 functions as a traveling wheel at this time, and the speed of the right displacement of the outer wheel 601 is the same as the transverse displacement speed of the bending part 102 of the drag chain 1.

[0023] The push wheel 4 is also pushed by the abutment of the bending part 102 of the drag chain 1, but the difference is that the former moves to the right, and the inner edge of the bending part 102 of the drag chain 1 contacts the push wheel 4, which moves to the left, and the latter moves to the left, and the outer edge of the bending part 102 of the drag chain 1 contacts the push wheel 4, which moves to the left, thereby driving the entire support bridge 2 to move to the left. As a traveling wheel, the outer wheel 601 also rolls to the left, thereby making the drag chain guide disc 6 and the bending part 102 of the drag chain 1 move synchronously in transverse displacement. Compared with the traditional integrated drag chain guide disc 6, this application is divided into an inner wheel and an outer wheel that rotate independently, and there is a speed difference between the inner wheel and the outer wheel, which effectively reduces the friction caused by the speed difference between the upper part of the drag chain and the drag chain guide disc 6, thereby effectively improving the service life of the drag chain 1.

[0024] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
