Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a deflectable metal drag chain. Background Art

[0002] Metal drag chains are mechanical protection devices used to protect cables, gas pipes and liquid pipes from external damage in industrial equipment. They are composed of metal links that keep these pipelines safe and tidy when the equipment is in motion. Metal drag chains can reduce friction and wear, improve the reliability and service life of equipment, and are widely used in industrial automation, machinery manufacturing and CNC processing.

[0003] When existing metal drag chains are dragged and folded by equipment, they can only move in a fixed two-dimensional plane and cannot be offset, which limits their applicability in complex working environments, resulting in restricted equipment layout, inconvenient installation, low space utilization, and increased maintenance costs. At the same time, since they cannot flexibly respond to multi-dimensional motion paths, their performance in steering, obstacle avoidance, etc. is limited, reducing the flexibility and efficiency of the entire system. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that the metal drag chain in the prior art can only be folded in a fixed two-dimensional plane when being dragged by the equipment and cannot be offset, which limits its applicability in complex working environments, resulting in limited equipment layout, inconvenient installation, low space utilization, and increased maintenance costs. At the same time, due to the inability to flexibly respond to multi-dimensional motion paths, its performance in steering, obstacle avoidance, etc. is limited, reducing the flexibility and efficiency of the entire system. Therefore, a displaceable metal drag chain is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A displaceable metal drag chain comprises side chain plates, an intermediate chain plate, a transition chain plate and an edge chain plate, wherein the side chain plates are fixedly arranged on both sides of the intermediate chain plate, a docking ring groove is provided at one end of the side chain plate, a transition chain plate is rotatably connected to the other end of the side chain plate, a transition connection component is provided between the transition chain plate and the edge chain plate for allowing the entire drag chain to be arbitrarily displaced in three-dimensional space, a connecting convex ring is provided on the inner side surface of the edge chain plate, and the cross-sectional size of the connecting convex ring is the same as the cross-sectional size of the docking ring groove.

[0007] Optionally, the transition connection assembly includes a horizontal seat, a vertical seat, and a docking block, one end of the horizontal seat is fixedly connected to the side of the transition chain plate, and a horizontal pin is horizontally fixedly provided on the side of the horizontal seat.

[0008] Optionally, the outer wall of the horizontal pin is rotatably connected to the side of the docking block, a vertical seat is fixedly provided on the side of the edge chain plate, and a vertical pin shaft is fixedly provided on the top of the vertical seat along the vertical direction.

[0009] Optionally, the other end of the docking block is rotatably connected to a vertical pin shaft, and the circular array of the outer wall of the edge chain plate has a limiting component that limits the entire metal drag chain from deflecting.

[0010] Optionally, the limiting assembly includes a limiting chain plate, fixing bolts, and a guide block, and the circular array of guide blocks on the four walls of the edge chain plate.

[0011] Optionally, a transverse groove is opened on the side of the limiting chain plate, and the fixing bolt passes through the transverse groove and is threaded into the side door of the guide block, and the width of the head of the fixing bolt is greater than the width of the head of the transverse groove.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model adds additional transition chain plates and edge chain plates to the chain links of traditional metal drag chains, and the transition chain plates and the edge chain plates are additionally provided with transition connections, so that the entire metal drag chain can be offset in a three-dimensional plane when being dragged and folded by the equipment. This can completely solve the problem that the traditional metal drag chain can only be moved in a fixed two-dimensional plane when being dragged and folded by the equipment, and cannot be offset, which limits its applicability in complex working environments, resulting in limited equipment layout, inconvenient installation, low space utilization, increased maintenance costs, and the inability to flexibly cope with multi-dimensional motion paths.

[0014] 2. The utility model sets limit components around the edge chain plate. When the four sets of limit components are selected to extend into or retract from the side of the transition chain plate, the entire metal drag chain can be offset or not offset. The system becomes more versatile and can adapt to working conditions of different shapes and environments, providing higher adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 The displaceable metal drag chain comprises a side chain plate 2, an intermediate chain plate 3, a transition chain plate 4 and an edge chain plate 10. The side chain plates 2 are fixedly arranged on both sides of the intermediate chain plate 3. A docking ring groove 1 is provided at one end of the side chain plate 2. The other end of the side chain plate 2 is rotatably connected with the transition chain plate 4. A transition connection component is provided between the transition chain plate 4 and the edge chain plate 10, which allows the entire drag chain to be arbitrarily displaced in three-dimensional space.

[0021] A connecting convex ring 7 is provided on the inner side surface of the edge chain plate 10, and the cross-sectional size of the connecting convex ring 7 is the same as the cross-sectional size of the docking ring groove 1. Multiple metal chains can be connected in series through the connecting convex ring 7 and the docking ring groove 1. The transition connection component includes a horizontal seat 14, a vertical seat 12, and a docking block 13. One end of the horizontal seat 14 is fixedly connected to the side surface of the transition chain plate 4, and a horizontal pin 8 is fixedly arranged horizontally on the side surface of the horizontal seat 14. The outer wall of the horizontal pin 8 is rotatably connected to the side surface of the docking block 13. A vertical seat 12 is fixedly arranged on the side surface of the edge chain plate 10, and a vertical pin shaft 9 is fixedly arranged on the top of the vertical seat 12 along the vertical direction. The other end of the docking block 13 is rotatably connected to the vertical pin shaft 9, and the horizontal pin 8 and the vertical pin shaft 9 are perpendicular to each other.

[0022] The circular array on the outer wall of the edge chain plate 10 has a limit assembly that limits the entire metal drag chain from being displaced. The limit assembly includes a limit chain plate 5, a fixing bolt 6, and a guide block 11. The circular array on the four walls of the edge chain plate 10 has a guide block 11. A transverse groove 51 is opened on the side of the limit chain plate 5. The fixing bolt 6 passes through the transverse groove 51 and is screwed into the side door of the guide block 11. The head width of the fixing bolt 6 is larger than the head width of the transverse groove 51. A hole matching the diameter of the fixing bolt 6 is reserved on the side of the guide block 11. The guide block 11 has the same width as the transverse groove 51. The guide block 11 cooperates with the transverse groove 51 to limit the limit chain plate 5 to only be able to move horizontally. The transverse groove 51 has a certain length. The transverse groove 51 allows the entire limit chain plate 5 to move horizontally within a certain distance. When the limit chain plate 5 is displaced to any extreme position, the head of the limit chain plate 5 extends into the four sides of the transition chain plate 4 or detaches from the four sides of the transition chain plate 4.

[0023] It should be added that, when installing the entire metal drag chain, only one drag chain structure needs to be connected in series to the entire drag chain.

[0024] The specific implementation steps and principles of the utility model are as follows:

[0025] When the entire drag chain needs an offset function, the worker loosens the four sets of fixing bolts 6 and moves the four sets of limiting chain plates 5 horizontally to a position that does not hinder the transition chain plates 4. At this time, the entire chain link with the vertical pin shaft 9, horizontal pin shaft 8 and docking block 13 can move in a three-dimensional plane.

[0026] When the entire drag chain does not need the offset function, the worker loosens the four sets of fixing bolts 6 and moves the four sets of limiting chain plates 5 horizontally to a position that blocks the transition chain plates 4. At this time, the transition chain plates 4 cannot rotate or twist around the edge chain plates 10.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
