Technical Field
[0001] This utility model relates to the technical field of high-voltage circuit breaker production tools, specifically to a guide transport vehicle for a high-voltage circuit breaker production line. Background Technology
[0002] A high-voltage circuit breaker is a switching device capable of closing, carrying and interrupting current under normal circuit conditions, and capable of closing, carrying and interrupting current under abnormal circuit conditions (such as short circuits) within a specified time.
[0003] The structure of a high-voltage circuit breaker includes: moving contacts and stationary contacts. When the circuit breaker is closed, the moving contacts and stationary contacts are in contact, and the circuit is connected. When the circuit breaker is open, the moving contacts and stationary contacts are separated, and the circuit is broken. Conductive rods are used to connect the contacts and external circuits to ensure that current can pass smoothly. Arc extinguishing devices are used to quickly extinguish the arc, preventing the arc from damaging the contacts and equipment, and preventing the arc from continuing to burn and causing short circuit faults. Insulating components are used to ensure that there is sufficient insulation strength between the conductive parts of the circuit breaker and the ground, as well as between each phase, to prevent leakage and short circuits. Operating mechanisms are used to drive the circuit breaker to open and close. Transmission systems are used to transmit the power of the operating mechanisms to the conductive parts of the circuit breaker to realize the opening and closing actions. Supporting components are used to support the various components of the circuit breaker.
[0004] After the components of a high-voltage circuit breaker are assembled, inspected, and tested on the production line, the finished product is obtained. Typically, the circuit breaker enclosure is first placed on a handcart, and then workers push the handcart sequentially to the designated process positions, where they assemble the specified components. Traditional handcarts, as material carts, lack guiding functionality. On the production line, when workers move multiple handcarts from one process workbench to the next, they are prone to collisions and deviations from their intended direction. Furthermore, the arrangement of multiple handcarts can be cluttered and congested, easily obstructing worker walkways and other material transport routes, which is detrimental to the assembly efficiency of high-voltage circuit breakers.
[0005] Therefore, in order to move and arrange material carts neatly, there is an urgent need in this technical field for a guide transport vehicle for a high-voltage circuit breaker production line. Utility Model Content

Detailed Implementation
[0024] This utility model embodiment provides a guide transport vehicle for a high-voltage circuit breaker production line. The overall technical concept is as follows:
[0025] Guide rails are installed on the production line floor, distributed at corresponding process positions. The bottom of the chassis is the traveling assembly, and the top of the chassis is equipped with the high-voltage circuit breaker housing. The guide channel of the traveling assembly is inserted into the guide rail, and the wheel surfaces of the limit wheels of the traveling assembly abut against the guide rail. Multiple chassis move along the guide rail one after another. Workers at the corresponding process positions install the required parts into the housing, and then push the chassis from one process position to the next process position. The chassis move neatly along the guide rail to avoid deviating from the direction of movement, and the high-voltage circuit breaker housing can be neatly placed at the next process position.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] See Figures 1 to 5 The preferred embodiment of this utility model.
[0028] A guide transport vehicle for a high-voltage circuit breaker production line includes:
[0029] Frame 1, running gear 2, guide rail 3;
[0030] The walking assembly 2 includes a support rod 21, omnidirectional wheels 22 and limiting wheels 23. The two omnidirectional wheels 22 are respectively installed at the left and right ends of the support rod 21, and the two limiting wheels 23 are respectively installed on the left and right sides of the middle position of the support rod 21, forming a guide channel 24 between the two limiting wheels 23.
[0031] Two walking components 2 are respectively provided at the front and rear ends of the bottom of the frame 1. The guide rail 3 passes through the guide channel 24 of the two walking components 2 in sequence. The wheel surface of the limiting wheel 23 abuts against the guide rail 3. The guide rail 3 is fixedly set on the ground. The omnidirectional wheel 22 is placed on the ground.
[0032] The beneficial effects or advantages of this utility model are as follows: Guide rails 3 are set on the ground of the production line and distributed at the corresponding process positions. The frame 1 of the material cart moves neatly along the guide rails 3 with the help of the limiting wheels 23 of the walking component 2, avoiding deviation from the direction of movement. After moving from one process position to the next process position, multiple frames 1 are neatly arranged according to the length direction of the guide rails 3, avoiding occupying the worker walking passage and other material transportation passages of the production line, which helps to improve the assembly efficiency of high voltage circuit breakers.
[0033] Furthermore, the walking assembly 2 also includes a limiting shaft 25 and a compression spring 26. The lower surface of the support rod 21 is provided with a strip groove 211. The two strip grooves 211 are symmetrically arranged about the middle position of the support rod 21. The upper end of the limiting shaft 25 is slidably connected to the strip groove 211. The limiting shaft 25 can slide back and forth along the length direction of the strip groove 211. The lower end of the limiting shaft 25 is rotatably connected to the center hole of the limiting wheel 23. One end of the compression spring 26 abuts against the upper end of the limiting shaft 25, and the other end of the compression spring 26 is fixedly connected to the strip groove 211.
[0034] The beneficial effects of this technical solution are as follows: The compression spring 26 helps to keep the limiting wheel 23 abutting against the guide rail 3. When the operator pushes the frame 1, the compression spring 26 also acts as a buffer, reducing the vibration of the frame 1 and making the frame 1 move stably. When the guide rail 3 passes through the guide channel 24, the guide rail 3 squeezes the limiting wheel 23, causing the compression spring 26 to deform accordingly. The distance between the two limiting wheels 23 can be adjusted accordingly, allowing the guide rail 3 to pass more smoothly between the two limiting wheels 23. Then the compression spring 26 returns to its original position, pushing the limiting shaft 25 to make the limiting wheel 23 abut against the guide rail 3.
[0035] Furthermore, the frame 1 includes uprights 11, support platforms 12, and connecting rods 13. The lower ends of the two uprights 11 are fixedly connected to the support rods 21 of the two walking components 2, respectively. The support rods 21 of the two walking components 2 are fixedly connected to both ends of the connecting rods 13, respectively. The upper ends of the two uprights 11 are fixedly connected to the two support platforms 12, respectively.
[0036] The beneficial effects of this technical solution are: the support platform 12 is used to install the box 4 of the high-voltage circuit breaker, the frame 1 carries the box 4 of the high-voltage circuit breaker and moves it along the guide rail 3, and the height of the column 11 makes the box 4 of the high-voltage circuit breaker at a suitable installation height, so that the staff can stand directly next to the frame 1 to assemble it.
[0037] Furthermore, the support platform 12 is provided with screw holes (not shown), and the high-voltage circuit breaker housing 4 is installed between the two support platforms 12. The high-voltage circuit breaker housing 4 is provided with through holes (not shown), and bolts 14 pass through the through holes and are then locked to the screw holes.
[0038] The beneficial effects of this technical solution are as follows: During the component assembly process, the housing 4 is fixed to the support platform 12 by bolts 14. When the high-voltage circuit breaker is completed and the finished product is obtained, the bolts 14 are removed and the finished high-voltage circuit breaker is taken away from the support platform 12.
[0039] Furthermore, a material box 15 is fixedly installed on the upper surface of the support platform 12.
[0040] The beneficial effects of this technical solution are: improving the space utilization of the support platform 12, and the material box 15 is used to place tools, such as wrenches and screwdrivers, so that workers can easily access the tools during assembly.
[0041] This utility model discloses a guide transport vehicle for a high-voltage circuit breaker production line. It moves orderly and neatly along the guide rail 3 of the production line, avoiding deviation from the direction of movement as it is pushed from one process position to the next. Upon arrival at the corresponding process position, the components are neatly arranged, effectively avoiding obstruction of worker walkways and other material transport channels. At the entrance of the production line, the high-voltage circuit breaker housing 4 is installed on top of the frame 1. The frame 1 then carries the housing 4 sequentially through the process positions. Workers assemble the required components into the housing 4 in order. At the exit of the production line, the finished high-voltage circuit breaker is obtained. Workers remove the finished high-voltage circuit breaker from the frame 1 and finally package it.
