Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission and transformation, in particular to a branch busbar conductor assembly tooling. Background Technique

[0002] The existing branch busbar conductor assembly tooling is mostly used in the assembly of three-phase coaxial busbar conductors. It has the functions of adjustable installation position of the conductor and fixing the conductor, is suitable for installing the conductor in a relatively thick busbar cylinder, can prevent the conductor from being knocked and scratched by the busbar cylinder, and can reduce the labor intensity of workers to a certain extent.

[0003] However, it is found in the process of assembling the conductor in a thin branch busbar cylinder that most of the branch busbar conductor assembly tooling used in the existing technology is not easy to be taken out of the busbar cylinder. Therefore, before each use, the tooling needs to be adjusted to adapt to the corresponding busbar cylinder. Content of the Utility Model

[0004] In order to assemble the conductor in the busbar cylinder while reducing the knocking damage between the conductor and the busbar cylinder, the present application provides a branch busbar conductor assembly tooling.

[0005] A branch busbar conductor assembly tooling provided by the present application adopts the following technical scheme:

[0006] A branch busbar conductor assembly tooling for assembling a conductor in a busbar cylinder, characterized in that it includes a trolley bracket, on which there is a supporting arc groove for supporting the conductor, the supporting arc groove fits with the outer wall of the conductor, a plurality of guide wheels are rotatably connected to the trolley bracket, the plurality of guide wheels fit with the inner wall of the busbar cylinder, there is a mounting member for mounting the guide wheels on the trolley bracket, and a pull ring is provided on the trolley bracket.

[0007] By adopting the above technical scheme, the trolley bracket is supported by the guide wheels. After being supported, the trolley bracket can support the conductor under the action of the supporting arc groove, so that the center of the conductor is concentric with the center of the busbar cylinder, which is convenient for assembling the conductor into the busbar cylinder. The pull ring can cooperate with a pull rope to conveniently take out the trolley bracket from the busbar cylinder for repeated use. Therefore, for the assembly of busbar cylinders and conductors of the same size, there is no need to equip multiple assembly toolings, which saves costs.

[0008] Preferably, a gasket is provided on the inner wall of the supporting arc groove, and the gasket is used to reduce the friction between the conductor and the trolley bracket.

[0009] By adopting the above technical scheme, through the setting of the gasket, the friction between the conductor and the trolley bracket is reduced. Therefore, during the assembly process of the conductor, the conductor is not easily knocked and damaged, and due to the supporting effect of the trolley bracket on the conductor, the busbar cylinder is not easily knocked and damaged during the assembly process of the conductor.

[0010] Preferably, the gasket is made of polytetrafluoroethylene.

[0011] By adopting the above technical solution, polytetrafluoroethylene has extremely high chemical stability and is almost insoluble in any solvent. Therefore, the conductor is not likely to react with the gasket due to friction during the assembly process. In addition, polytetrafluoroethylene has an extremely low coefficient of friction and is often used as a lubricant, making the conductor not easily damaged during the assembly process. Polytetrafluoroethylene also has good anti-aging endurance, effectively extending the service life of the assembly tooling.

[0012] Preferably, there are four guide wheels. The four guide wheels are evenly divided into two groups and symmetrically arranged on both sides of the trolley bracket. The two guide wheels on one side are arranged at both ends in the thickness direction of the trolley bracket.

[0013] By adopting the above technical solution, through the setting and distribution of the four guide wheels, the stability of the trolley bracket sliding in the busbar duct is improved while reducing costs.

[0014] Preferably, the mounting member includes a pin shaft screw. A deep groove ball bearing is press-fitted on the guide wheel. The outer wall of the pin shaft screw fits with the inner wall of the deep groove ball bearing. An installation threaded hole that is threadedly matched with the pin shaft screw is provided on the trolley bracket.

[0015] By adopting the above technical solution, the guide wheel is fixed to the trolley bracket through the pin shaft screw, which not only facilitates the disassembly and assembly of the guide wheel, but also effectively restricts the loosening or falling off of the guide wheel during the sliding process of the trolley bracket through the fixation of the pin shaft screw, improving the sliding stability of the trolley bracket. With the cooperation of the deep groove ball bearing and the pin shaft screw, it is convenient for the guide wheel to rotate, thus facilitating the sliding of the trolley bracket in the busbar duct.

[0016] Preferably, the guide wheel is made of polyurethane.

[0017] By adopting the above technical solution, polyurethane has good wear resistance, effectively reducing the damage to the busbar duct. Moreover, polyurethane has excellent elasticity and can quickly return to its original state after being stressed, so it is not easy to change the overall height of the trolley, improving the service life of the assembly tooling.

[0018] Preferably, there are two pull rings. The two pull rings are symmetrically arranged on both sides of the same end face of the trolley bracket.

[0019] By adopting the above technical solution, the two pull rings are symmetrically arranged on both sides of the same end face of the trolley bracket. The pull rope can pass through the two pull rings in sequence. Therefore, when the trolley bracket is taken out through the pull rope, the stability of the trolley bracket sliding in the busbar duct is improved.

[0020] Preferably, the trolley bracket is made of hard aluminum alloy.

[0021] By adopting the above technical solution, the hard aluminum alloy has the advantages of high strength, machinability and corrosion resistance, making the manufactured trolley bracket have a certain rigidity and not easy to be corroded, prolonging the service life of the trolley bracket, and being convenient for machining.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By supporting the trolley bracket through the guide wheel, the supported trolley bracket can support the conductor under the action of the supporting arc groove, so that the center of the conductor is concentric with the center of the busbar cylinder, which is convenient for assembling the conductor into the busbar cylinder. The pull ring can cooperate with the pull rope to conveniently take out the trolley bracket from the busbar cylinder for repeated use. Therefore, it is not necessary to equip multiple assembly tools for assembling the busbar cylinder and the conductor of the same size, saving costs.

[0024] 2. Through the setting of the gasket, the friction between the conductor and the trolley bracket is reduced, so that the conductor is not easily knocked and damaged during the assembly process of the conductor, and due to the supporting effect of the trolley bracket on the conductor, the busbar cylinder is not easily knocked and damaged during the assembly process of the conductor.

[0029] The following is a further detailed description of the present invention in conjunction with the attached Figures 1-3 drawings.

[0030] The embodiment of the present application discloses a branch busbar conductor assembly tool for assembling a conductor into a busbar cylinder. Referring to Figure 1 and Figure 2 , it includes a trolley bracket. The trolley bracket is integrally processed from a hard aluminum alloy material. In the embodiment of the present application, the hard aluminum alloy has the grade of LY12, which has the advantages of high strength, machinability and corrosion resistance, making the manufactured trolley bracket have a certain rigidity and not easy to be corroded, prolonging the service life of the trolley bracket, and being convenient for machining.

[0031] Referring to Figure 1 andFigure 3 The trolley bracket is provided with a supporting arc groove for supporting the conductor. The supporting arc groove is integrally formed when the trolley bracket is manufactured. The supporting arc groove is arranged along the thickness direction of the trolley bracket. A pad is arranged on the inner wall of the supporting arc groove. The pad is used to reduce the friction between the conductor and the trolley bracket. The conductor placed on the trolley bracket fits with the end face of the pad facing away from the trolley bracket. The setting of the pad reduces the friction between the conductor and the trolley bracket, so that the conductor is not easily bumped and damaged during the assembly of the conductor. Moreover, the supporting effect of the trolley bracket on the conductor makes the busbar barrel not easily bumped and damaged during the assembly of the conductor.

[0032] The gasket is made of polytetrafluoroethylene, which has extremely high chemical stability and is almost insoluble in any solvent. The conductor is not easy to react with the gasket during the assembly process. In addition, polytetrafluoroethylene has an extremely low friction coefficient and is often used as a lubricant, making it difficult for the conductor to be damaged during the assembly process. Polytetrafluoroethylene also has good anti-aging resistance, which effectively extends the service life of the assembly tooling.

[0033] Reference Figure 1 , Figure 2 and Figure 3 There are multiple guide wheels rotatably connected to the trolley bracket, and the inner wall of the busbar barrel is fitted with the multiple guide wheels. The radial extension line of the guide wheel passes through the center of the supporting arc groove. There are four guide wheels, which are evenly divided into two groups and symmetrically arranged on both sides of the trolley bracket. The two guide wheels on one side are arranged at both ends of the thickness direction of the trolley bracket. The friction between the trolley bracket and the busbar barrel is reduced by the setting of the guide wheels. The setting and distribution of the four guide wheels improves the sliding stability of the trolley bracket in the busbar barrel while reducing the cost.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The trolley bracket is provided with a mounting part for installing the guide wheel, the mounting part includes a pin screw, the trolley bracket is provided with a mounting threaded hole matched with the pin screw thread, a deep groove ball bearing is crimped on the guide wheel, the outer wall of the pin screw fits with the inner wall of the deep groove ball bearing, and the guide wheel is fixed to the trolley bracket by the pin screw, which is not only convenient for disassembly and assembly of the guide wheel, but also can effectively limit the loosening or falling off of the guide wheel during the sliding process of the trolley bracket through the pin screw fixation, thereby improving the sliding stability of the trolley bracket, and with the cooperation of the deep groove ball bearing and the pin screw, the rotation of the guide wheel is facilitated, thereby facilitating the sliding of the trolley bracket in the busbar.

[0035] The guide wheel is made of polyurethane, which has good wear resistance and effectively reduces the damage to the busbar barrel. Polyurethane also has excellent elasticity and can quickly return to its original state after being subjected to force, so it is not easy to change the overall height of the trolley, thereby improving the service life of the assembly tooling.

[0036] Refer to Figure 1 、 Figure 2 and Figure 3 A pull ring is provided on the trolley support. The pull ring can cooperate with a pull rope to conveniently take out the trolley support from the busbar barrel for repeated use. Therefore, multiple assembly tools do not need to be equipped for the assembly of busbar barrels and conductors of the same size, saving costs. There are two pull rings, and the two pull rings are symmetrically arranged on both sides of the same end face of the trolley support. The pull rope can pass through the two pull rings in sequence. When the trolley support is taken out through the pull rope, the stability of the trolley support sliding in the busbar barrel is improved.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
