Description

Technical Field

[0001] This utility model relates to the technical field of cable chain repair equipment, and more specifically, to a temporary support structure for repairing plastic cable chains. Background Technology

[0002] Current plastic cable chains are generally composed of several units connected by rotating ends. They are mainly used in reciprocating motion applications and can provide traction and protection for built-in cables, oil pipes, air pipes, water pipes, etc. They are widely used in CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, lifting and transportation equipment, automated warehouses and other scenarios.

[0003] Each unit consists of left and right chain links, upper and lower cover plates, and a middle partition. When the internal cables need maintenance, the upper cover plate of each unit section of the cable chain can be opened to facilitate the adjustment and maintenance of the internal cables. In actual maintenance, the entire cable chain needs to be temporarily stopped and placed in a static position. In this position, the cable chain in the bending area needs to withstand greater torsional force and pressure. If the maintenance time is too long, the plastic cable chain in the bending area is prone to deformation and damage, affecting the service life of the cable chain. Utility Model Content

[0004] The purpose of this invention is to provide a temporary support structure for the maintenance of plastic cable chains. This temporary support structure can provide temporary support for the bent area units of the plastic cable chain in a static state, protect several units in the area when the maintenance time is long, and improve the service life of the plastic cable chain. The temporary support structure can be quickly removed after the maintenance is completed without affecting the normal operation of the cable chain.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A temporary support structure for repairing a plastic cable chain includes a track, on which an equipment connection base is slidably mounted. A plastic cable chain is connected to the side of the equipment connection base. The lower horizontal section of the plastic cable chain is laid inside a bottom groove. The temporary support structure includes several support units, each of which includes a left-right symmetrical base plate. An inverted concave bracket is erected and connected at the middle position of the upper surface of the left-right symmetrical base plate. The cross-section of the inverted concave bracket is a regular polygon. Regular polygonal protrusions are fixed at both the front and rear ends of the upper surface of the base plate. Adjacent support units are connected by a clamping plate that is embedded into the upper limit of the adjacent regular polygonal protrusions. The front and rear ends of the clamping plate are machined with through grooves of the same shape as the regular polygonal protrusions.

[0007] As a further optimization of this solution, the inverted concave bracket is equipped with symmetrical support components, each of which includes a symmetrical upper clamping plate and a lower clamping plate. The outer sides of the upper and lower clamping plates are fixedly connected to telescopic brackets, and the inner sides of the upper and lower clamping plates are machined with slots whose shape matches the cross-sectional shape of the inverted concave bracket. The telescopic bracket has an L-shaped support plate connected to the outer end of the telescopic section, and the L-shaped support plate supports the upper and lower edges of one side of the plastic drag chain.

[0008] As a further optimization of this solution, the horizontal section of the L-shaped pallet does not exceed the inner edge of the link plate of the plastic cable chain.

[0009] As a further optimization of this solution, the upper clamping plate includes two parallel convex seats. A top plate is fixed at the middle position of the upper end of the two parallel convex seats, and a stabilizing support rod is fixed at both sides of the upper end of the two parallel convex seats. The non-telescopic section of the telescopic bracket is fixed to the outer side of the top plate, and the telescopic length is limited by locking bolts on the outer side of the non-telescopic section of the telescopic bracket. The upper clamping plate and the lower clamping plate are connected together by bolts on the front and rear sides.

[0010] As a further optimization of this solution, a vertical component storage slot is fixed on the inner side of one vertical section of the inverted concave bracket, and supports are fixed at both the upper and lower ends of the outer side of one vertical section of the inverted concave bracket, with rollers connected to the supports via a rotating shaft.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model designs several support unit structures, which can provide temporary support according to the static posture of various lengths of the plastic cable chain after it stops. By using a clamping plate to limit and connect an appropriate number of support units along the direction of the plastic cable chain, the bending area of ​​the plastic cable chain is temporarily supported. When the maintenance time is long, several plastic cable chain units in this area are protected, which plays a role in temporary support and protection.

[0013] This utility model, through the design of the upper and lower clamping plate structures, allows for flexible installation on the inverted concave bracket, making it suitable for cable chain types of different widths. At the same time, through the design of the telescopic bracket structure, the support height of the L-shaped support plate can be changed, thus making it suitable for cable chain types of different bending heights, resulting in good applicability.

[0014] This utility model incorporates an inverted concave bracket structure with rollers, allowing for quick disassembly after maintenance. The disassembled components can be placed inside the component storage slot for easy overall transfer. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] To address the problem that during actual maintenance, the cable chain needs to be temporarily stopped and placed in a static position. In this position, the cable chain in the bending area needs to withstand large torsional forces and pressures. When the maintenance time is too long, the plastic cable chain in the bending area is prone to deformation and damage, which affects the service life of the cable chain.

[0022] like Figure 1 As shown, this application includes a track 1, on which an equipment connection base 2 is slidably installed. A plastic drag chain 3 is connected to the side of the equipment connection base 2. The horizontal section below the plastic drag chain 3 is laid inside the bottom groove 4. The temporary support structure includes several support units, each of which includes a left-right symmetrical base plate 5. An inverted concave bracket 6 is erected and connected at the middle position of the upper surface of the left-right symmetrical base plate 5. The cross-section of the inverted concave bracket is a regular polygon. Regular polygonal protrusions 7 are fixed at the front and rear ends of the upper surface of the base plate 5. Adjacent support units are connected by a clamping plate 8 which is embedded into the upper limit of the adjacent regular polygonal protrusions 7. The front and rear ends of the clamping plate 8 are machined with through grooves with the same shape as the regular polygonal protrusions 7.

[0023] like Figure 2As shown, the inverted concave bracket 6 is equipped with symmetrical support components, each of which includes an upper clamping plate 9 and a lower clamping plate 10 with symmetrical structure. The outer sides of the upper clamping plate 9 and the lower clamping plate 10 are fixedly connected to a telescopic bracket 11, and the inner sides of the upper clamping plate 9 and the lower clamping plate 10 are machined with slots whose shape matches the cross-sectional shape of the inverted concave bracket 6. The telescopic bracket 11 is connected to an L-shaped support plate 12 at the outer end of its telescopic section. The L-shaped support plate 12 supports the upper and lower edges of one side of the plastic drag chain 3, and the horizontal section of the L-shaped support plate 12 does not exceed the inner edge of the link plate of the plastic drag chain 3.

[0024] like Figure 3 As shown, the upper clamping plate 9 includes two parallel convex seats. A top plate 14 is fixed at the middle position of the upper end of the two parallel convex seats, and a stabilizing support rod 15 is fixed at both sides of the upper end of the two parallel convex seats. The non-telescopic section of the telescopic bracket 11 is fixed to the outer side of the top plate 14, and the telescopic length is limited by the locking bolt 17 on the outer side of the non-telescopic section of the telescopic bracket 11. The upper clamping plate 9 and the lower clamping plate 10 are connected together by bolts 16 on the front and rear sides.

[0025] like Figure 4 As shown, a vertical component storage slot 13 is fixed on the inner side of the vertical section of one side of the inverted concave bracket 6, and a support 18 is fixed at both the upper and lower ends of the outer side of the vertical section of one side of the inverted concave bracket 6. A roller 19 is connected to the support 18 through a rotating shaft.

[0026] Specifically, when maintenance is required on the plastic cable chain 3, its operation is stopped, and the plastic cable chain 3 is in a static state. Based on the length of the static plastic cable chain 3, an appropriate number of support units are selected. Adjacent support units are connected by locking plates for limiting their movement. Figure 1 The bending length of the plastic cable chain 3 only requires one support unit. The horizontal section of the L-shaped support plate 12 does not exceed the inner edge of the chain link plate of the plastic cable chain 3 and provides corresponding support for the inner and outer sides of the upper and lower cable chain units, thereby supporting the entire bending area. When the maintenance time is long, it protects several plastic cable chain units in this area and plays a role in temporary support and protection.

[0027] After maintenance, the length of the telescopic bracket 11 can be shortened, and components such as the upper clamping plate 9, lower clamping plate 10, and clamping plate 8 can be removed from the inverted concave bracket 6 and placed into the component storage slot 13. Figure 4 As shown, the tilted concave bracket 6 pushes the temporary support structure away.
