Description

Technical Field

[0001] This invention relates to the field of high-voltage switch assembly technology, and more specifically to a conductor assembly tooling. Background Technology

[0002] With the rapid development of the national economy and the power industry, the power grid has become increasingly large. Gas-insulated switchgear (GIS) has been widely adopted in substations in recent years due to its advantages such as less susceptibility to external environmental influences, less need for frequent maintenance, and smaller footprint. GIS equipment refers to the optimized and organic combination of primary equipment in a substation, excluding transformers, including conductors, electrical connections, busbars, circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, surge arresters, cable terminals, and incoming / outgoing bushings, sealed in a container filled with SF6 gas for insulation. The assembly and application of conductors and electrical connections are particularly widespread in GIS power stations.

[0003] In GIS equipment, almost every assembly unit involves the assembly of conductors and electrical connections. The clamping force of the contact fingers in the electrical connection is relatively large, and a large pushing force is required to insert the conductor during assembly. The traditional assembly mode is to manually clamp and push it in, which makes the conductor assembly process difficult, labor-intensive, and time-consuming.

[0004] Therefore, how to provide a conductor assembly tooling that can reduce labor intensity, save working hours, and improve production efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a conductor assembly fixture that solves the problem of difficult conductor assembly and can avoid bumps and scratches to the busbar and conductor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A conductor assembly fixture, comprising: Base The first lifting platform has its fixed end vertically fixed to the top surface of the base for height adjustment. An upright plate, the lower end of which is fixed to the lifting end of the first elevator; A clamp, which is hinged to the vertical plate and has one end that can clamp the cylindrical flange of the equipment; The second lifting platform is located inside the clamp and its fixed end is vertically fixed to the surface of the upright plate for linear adjustment; the conductor is clamped to the lifting end of the second lifting platform and can be pushed into the equipment as the second lifting platform moves.

[0007] The beneficial effect of the technical solution of the present invention is that by adjusting the height of the vertical plate through the first elevator, the clamp can be clamped to the cylindrical flange of the equipment. By clamping the conductor to the lifting end of the second elevator, the action of the second elevator can provide thrust to push the conductor into the equipment, thereby realizing the assembly of the conductor on the equipment.

[0008] Preferably, the lifting end of the second elevator is fixed with a support, and one end of the conductor can be engaged in the support. Engaging the conductor with the support facilitates the insertion of the conductor.

[0009] Preferably, the bottom surface of the base is rotatably connected to multiple casters. The casters facilitate the movement of the tooling and enable the assembly of different equipment.

[0010] Preferably, the base includes a fixed plate and multiple channel steels fixed to the bottom surface of the fixed plate, with multiple traveling wheels rotatably connected to the bottom surface of the channel steels; the fixed end of the first elevator is fixed to the top surface of the fixed plate. The channel steels enable the installation of the traveling wheels, and also allow for a certain distance between the fixed plate and the ground, facilitating the operation of the first elevator.

[0011] Preferably, the clamp includes an upper clamp and a lower clamp; the upright plate is arranged opposite to the cylindrical flange; pins are fixed to the upper and lower ends of the side of the upright plate away from the cylindrical flange; the upper clamp and the lower clamp are respectively hinged to the two pins, and one end of each clamp is fixed with a hook that can be hooked to the cylindrical flange. By hooking the upper clamp and the lower clamp to the upper and lower end faces of the cylindrical flange, the hinged connection between the upper clamp and the lower clamp facilitates hooking and positioning.

[0012] Preferably, the device further includes a first spring and a second spring; the two ends of the first spring are respectively fixed to the end of the lower clamp away from the hook and the top surface of the base; the two ends of the second spring are respectively fixed to the end of the upper clamp away from the hook and the surface of the upright plate. The springs connect the clamp to the upright plate or base, ensuring a proper engagement between the clamp and the cylinder flange during conductor insertion.

[0013] Preferably, both the first and second lifting platforms include a control box, a worm gear, a lead screw, and a handwheel. The control box is fixed to the top surface of the base or the side of the upright plate facing the cylinder flange. The worm gear is rotatably connected inside the control box. The axis of the lead screw is arranged perpendicular to the axis of the worm gear and passes through the control box, meshing and transmitting power with the worm gear. The handwheel is fixed to one end of the worm gear. The lifting platform adopts a worm gear and lead screw configuration, and the worm gear is driven to rotate by the handwheel, converting the rotation of the worm gear into linear movement of the lead screw.

[0014] Preferably, a sleeve is fixed to the bottom surface of the base or the side of the upright plate away from the cylindrical flange; the end of the lead screw away from the upright plate or the end of the lead screw away from the conductor is inserted into the sleeve; an observation hole is provided on the outer wall of the sleeve. The sleeve serves as a protective sleeve for the lead screw, and the stroke of the lead screw can be observed through the observation hole.

[0015] Preferably, U-shaped handles are fixed on both sides of the side of the upright plate away from the cylinder flange. The handles facilitate the hoisting and transfer of the assembly fixture.

[0016] Preferably, the second elevator is electrically connected to a motor. Driving the second elevator with the motor provides sufficient thrust to ensure the efficiency and quality of conductor assembly.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] See appendix Figure 1 According to embodiment 5 of the present invention, a conductor assembly fixture solves the problem of difficult conductor assembly in existing GIS equipment and avoids collisions and scratches to the busbar cylinder and conductor. The fixture includes a base 1, a first lifting platform 3, a vertical plate 4, a clamp 7, and a second lifting platform 5. The fixed end of the first lifting platform 3 is vertically fixed to the top surface of the base 1 for height adjustment. The lower end of the vertical plate 4 is fixed to the lifting end of the first lifting platform 3. The clamp 7 is hinged to the vertical plate 4, and one end of it can be clamped to the cylinder flange 9 of the equipment. The second lifting platform 5 is located inside the clamp 7, and its fixed end is vertically fixed to the plate surface of the vertical plate 4 for linear adjustment. The conductor 10 is clamped to the lifting end of the second lifting platform 5 and can be pushed into the equipment as the second lifting platform 5 moves.

[0023] like Figure 1 and 2 As shown, the first lift is arranged vertically on the top surface of the base, and the upright plate is fixed on the first lift. The lifting action of the first lift can adjust the height of the upright plate. The second lift is arranged vertically on the first lift and fixed on the plate. The conductor is clipped onto the second lift. The lifting action of the second lift can provide thrust to push the conductor into the equipment.

[0024] To further optimize the above technical solution and ensure that the second elevator can provide sufficient thrust to meet the conductor assembly requirements, the second elevator 5 is electrically connected to a motor 8.

[0025] In this embodiment, the clamp 7 includes an upper clamp 71 and a lower clamp 72; the upright plate 4 is arranged opposite to the cylindrical flange 9; pins 44 are fixed at the upper and lower ends of the side of the upright plate 4 away from the cylindrical flange 9; the upper clamp 71 and the lower clamp 72 are respectively hinged to the two pins 44, and one end of each is fixed with a hook 73 that can be hooked to the cylindrical flange 9.

[0030] To further optimize the above technical solution and improve the structural strength of the upright plate, multiple stiffening plates 43 are fixed between the surface of the upright plate 4 and the surface of the connecting plate 42.

[0031] In some other specific embodiments, in order to facilitate the movement of the assembly tooling, the bottom surface of the base 1 is rotatably connected with multiple wheels 2.

Specifically, the control box of the first lifting platform is fixed to the top surface of the fixed plate. The lead screw of the first lifting platform is arranged perpendicular to the surface of the fixed plate and passes through both the control box and the fixed plate. The lower part of the lead screw is located in the gap between the fixed plate and the ground.

[0034] To further optimize the above technical solution, facilitate observation of the lead screw's stroke, and prevent the lead screw from detaching from the control box, a sleeve 16 is fixed to the bottom surface of the base 1 or the side of the vertical plate 4 away from the cylinder flange 9; the end of the lead screw 15 away from the vertical plate 4 or the end of the lead screw 15 away from the conductor 10 is inserted into the sleeve 16; an observation hole is provided on the outer wall of the sleeve 16.
