Abstract
Description
Technical Field
[0001] The invention relates to the technical field of anti-drag-break reinforcement connection of heavy-duty drag chains, and in particular to a anti-drag-break reinforcement connection method of heavy-duty drag chains. Background Art
[0002] A drag chain is a device that binds cables, air pipes, and oil pipes to facilitate their rotation or linear movement with the equipment. By wrapping cables, air pipes, oil pipes and other components, the drag chain prevents them from being affected by external forces such as friction, collision, and pulling during the movement of the equipment, thereby reducing the risk of wear, breakage and damage. In addition, the drag chain arranges cables and pipes in an orderly manner, avoiding failures and safety hazards caused by entanglement and interlacing, and improving the stability and reliability of the equipment.
[0003] In many cases, the cables and pipes loaded inside the drag chain are heavy, the running distance is long, the movements are frequent, and the running environment is harsh. High requirements are placed on the material strength, load-bearing capacity, and service life of the drag chain. At the same time, in order to cooperate with the equipment, the drag chain itself should also have the characteristics of compact size, light weight, smooth and flexible operation. Therefore, all drag chain manufacturers are actively looking for breakthroughs in the structure of the drag chain itself, solving problems through excellent and unique structural designs, and allowing the drag chain technology to continue to progress and develop.
[0004] At present, after a period of use, drag chains used in heavy-load situations may break due to uneven force, increased wear, stress concentration, etc. Once a chain breaks, it will have a great impact on the host equipment. Cables and pipes may get stuck, squeezed, or pulled apart, causing the host equipment to shut down and become unusable, or even cause serious safety accidents. Therefore, the present application provides a heavy-load drag chain anti-breakage and reinforced connection method to meet the needs. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide a heavy-duty drag chain anti-breaking and reinforced connection method to solve the existing chain breaking problem caused by uneven force, increased wear, stress concentration, etc. Once the chain breaks, it will have a great impact on the host equipment, and the cables and pipes may become stuck, squeezed, or pulled apart, causing the host equipment to shut down and be unusable, or even serious safety accidents.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a heavy-loaded drag chain anti-breakage reinforced connection method, comprising a drag chain and a roller support device installed on the drag chain, the axis of the drag chain is made of metal, the roller support device is fixed at both ends of the heavy-loaded drag chain and passes through several rollers, and at the same time, a steel wire rope with the same length as the drag chain is used to pass through the remaining rollers and fixedly connected to the heavy-loaded drag chain from head to tail, thereby enhancing the stability and carrying capacity of the drag chain.
[0007] Optionally, it also includes: preventing the lines from being scattered, using cable ties or cable ties to bundle multiple cables together to keep them neat, so as to prevent the lines from being scattered in the drag chain;
[0008] Avoid wire breakage, ensure that the cable can move with the drag chain without force, avoid cable twisting or curling, keep the cable straight and free of twist, and ensure that the cable has a 10% margin over the entire length to prevent twisting in the drag chain;
[0009] The long-distance anti-collapse drag chain includes a plurality of drag block groups, a first joint member and a second joint member. The lever support and opening and closing between the drag block groups are realized through the cooperation of the support column and the support hole, and the load-bearing gravity between the drag block groups is converted into the longitudinal tension at the bottom and the top force at the top, thereby increasing the strength and load-bearing capacity of the drag chain and effectively preventing the deformation and collapse of the drag chain.
[0010] The installation principle of drag chain wiring is to appropriately select the length and bending angle of the cable to maintain the freedom of the bending part of the cable to prevent the cables from interfering with each other. When cables with very different outer diameters are mixed in the wiring, partitions are used to separate the drag chain cables to reduce the occurrence of drag chain cable core breakage.
[0011] Optionally, the roller support device of the long-distance heavy-load drag chain includes a heavy-load drag chain, a drag chain roller support system, a frame, a linear rolling guide pair, a roller guide pair, a mobile trolley, a driving reduction motor, gears, racks, a robot and a drag chain connecting frame assembly. The roller support device reduces the excessive overhang and sliding friction problems caused by the drag chain being too long or too heavy a load through the roller support system, thereby reducing the movement resistance and preventing the trolley from being unable to move.
[0012] Optionally, the drag chain roller support system includes support rails, guide rollers, connecting plates, intermediate rollers, and supporting rollers; the head and tail are both guide rollers, supporting rollers are between adjacent connecting plates, and several intermediate rollers are equidistantly arranged in the center of the longer connecting plate.
[0013] Optionally, the intermediate roller comprises a roller, a rolling bearing, and a spindle. The spindle and the rolling bearing are transitionally fitted, the rolling bearing and the roller are interference fit, and both ends of the spindle are fixed to the connecting plate with nuts and washers.
[0014] Optionally, the cables, air pipes, liquid pipes: the drag chain connecting frame is led to the robot, drive motor, working tool and controller on the mobile trolley, and the driving reduction motor drives the trolley to reciprocate along the linear rolling guide pair through the gear rack transmission.
[0015] Optionally, the manufacturing method of the heavy-load drag chain includes multiple drag block groups, a first joint member and a second joint member; the multiple drag block groups are arranged between the first joint member and the second joint member and are respectively connected to them, and are limitedly hinged between the head and the tail; the drag block group includes two first chain plates with symmetrical structures and symmetrical positions and connecting members arranged on the upper and lower sides of the first chain plates, and the connecting members are used to connect the first chain plates and the carrying cables or pipelines.
[0016] Optionally, support holes are provided at both ends of the heavy-duty drag chain, and the axis is rotatably set in the support hole. Through the cooperation of the axis and the support hole, the lever support and opening and closing between the drag block groups are realized, and the load-bearing gravity between the drag block groups is converted into the longitudinal tension at the bottom and the top force at the top, thereby increasing the strength and load-bearing capacity of the drag chain and effectively preventing the deformation and collapse of the drag chain.
[0017] Optionally, the connection methods of the drag chain cable include welding connection and terminal connection. The welding connection is used in situations where high strength and durability are required, including the connection between a drive device and a control element. Welding can provide a very strong connection.
[0018] Optionally, the terminal connection uses special terminals and tools to connect the cable to the device; this method is convenient for maintenance and replacement, and the terminal connection can be quickly disassembled.
[0019] Compared with the prior art, the present invention has at least the following beneficial effects:
[0020] In the above solution, the drag chain axis is made of metal, which improves the strength of the drag chain and reduces the possibility of the drag chain breaking. The heavy-duty drag chain system provides comprehensive protection for the cable. The heavy-duty drag chain system has good bending performance and can bend freely during movement, reducing the bending pressure of the cable and avoiding cable fatigue and damage.
