[0045] Reference Figures 1 to 5As shown, this embodiment provides a switch production line. The switch production line includes guide rails 61 arranged in opposition to each other and a transport vehicle. The transport vehicle includes a base frame 1, an adjustment frame 11, a first side bracket 21, and a second side bracket 22. The adjustment frame 11 is slidably mounted on the base frame 1. The first side bracket 21 or the second side bracket 22 is mounted on the adjustment frame 11. The first side bracket 21 and the second side bracket 22 are located at opposite ends of the base frame 1. The first side bracket 21 and the second side bracket 22 are used to jointly secure the switch 9 to be assembled. A drive wheel 3 is provided on the lower end surface of the base frame 1 to drive the base frame 1 to move. The drive wheel 3 is used to move along the guide rails 61.

[0046] In this embodiment, the first side bracket 21 and the second side bracket 22 can jointly secure the switch 9 to be assembled. The drive wheel 3 is used to flexibly move the transport vehicle, thereby enabling reliable loading and flexible transportation of the switch 9, thereby improving the efficiency of switch operation. By providing an adjustment frame 11, the adjustment frame 11 is slidably mounted on the base frame 1, and the first side bracket 21 or the second side bracket 22 is fixed to the adjustment frame 11. The adjustment frame 11 slides relative to the base frame 1 to adjust the distance between the first side bracket 21 and the second side bracket 22, thereby adapting to switches 9 of different lengths and sizes, thereby enhancing practicality and compatibility.

[0047] Furthermore, the switch production line provided in this embodiment utilizes the aforementioned transport vehicle, enabling reliable loading and flexible transport of switches 9, thereby improving the operational efficiency of switches 9. Specifically, the drive wheels 3 are rotatably mounted on corresponding guide rails 61, enabling the transport vehicle to move along the extension direction of the guide rails 61, thereby rapidly transferring switches 9 between different workstations and ensuring reliable and stable transfer of switches 9 between different workstations.

[0048] Exemplarily, the switch 9 corresponding to the transport vehicle is preferably set to a 40.5kV new energy switch.

[0049] Specifically, the base frame 1 is provided with a slide rail 12, and the adjustment frame 11 includes a slider 111 disposed oppositely and having a sliding hole 1101. The slide rail 12 is slidably connected to the corresponding sliding hole 1101. The sliding connection between the slide rail 12 and the sliding hole 1101 strictly defines the sliding direction of the adjustment frame 11, ensuring reliable and stable adjustment of the spacing between the first side bracket 21 and the second side bracket 22.

[0050] Specifically, the slider 111 includes a slide groove 1111 and a fixed plate 1112. The fixed plate 1112 is disposed on the slide groove 1111 and together with the slide groove 1111, forms a sliding hole 1101. The slide groove 1111 is provided with a through-hole 1113, and the fixed plate 1112 has a corresponding screw hole 1114. A bolt is passed through the through-hole 1113 and is threadedly connected to the screw hole 1114. Specifically, the adjustment frame 11 is slidably connected to the slide rail 12 and remains fixed relative to the slide rail 12 after sliding into position.

[0051] The sliding groove 1111 and the fixing plate 1112 are combined to form a sliding hole 1101. The through hole 1113 is threadedly connected with the screw hole 1114 by a bolt, so that the sliding groove 1111 and the fixing plate 1112 can clamp the two sides of the sliding rail 12 together, that is, the sliding hole 1101 hugs the sliding rail 12, thereby fixing the adjustment frame 11 on the base frame 1.

[0052] Furthermore, the first side bracket 21 defines a plurality of first mounting holes 211 , and the second side bracket 22 defines a plurality of second mounting holes 221 . The switch 9 is fixed to the first mounting holes 211 and the second mounting holes 221 .

[0053] Specifically, different first mounting holes 211 and second mounting holes 221 can be selected on the first side bracket 21 and second side bracket 22 for connection according to different types of switches 9. Specifically, the switch 9 is provided with connection holes (not shown), and the connection holes and the first mounting holes 211 and the second mounting holes 221 can be connected via connectors such as bolt assemblies.

[0054] Specifically in this embodiment, the first side bracket 21 is fixed on the adjustment frame 11 , and the second side bracket 22 is fixed on the base frame 1 .

[0055] Furthermore, the adjustment frame 11 further includes a crossbeam 112, one surface of which is fixed to the slider 111 disposed opposite thereto, and the other surface of the crossbeam 112 is fixed to the first side bracket 21 or the second side bracket 22. Specifically, one surface of the crossbeam 112 is fixed to the slide groove 1111 of the slider 111, and the other surface of the crossbeam 112 is fixed to the first side bracket 21.

[0056] Exemplarily, the crossbeam 112 is fixed to the slider 111 and the first side bracket 21 by welding.

[0057] In this embodiment, the switch production line also includes a guide platform 62 positioned between opposing guide rails 61. The drive wheel 3 includes a wheel body 31 and a leg frame 32. The leg frame 32 is fixed to the lower end surface of the base frame 1. The wheel body 31 is connected to the leg frame 32 and rolls on the guide rail 61. Guide wheels 4 are rollingly mounted on the leg frame 32, and are configured to roll in contact with the side end surfaces of the guide platform 62. Specifically, the guide rails 61 and wheel bodies 31 are provided in a one-to-one correspondence, with the wheel bodies 31 rolling on the corresponding guide rails 61. The guide platform 62 is positioned between the guide wheels 4, and the guide wheels 4 roll on the corresponding side end surfaces of the guide platform 62. On the one hand, the setting of the guide wheel 4 can cooperate with the guide platform 62 in rolling in real time, making the flow process of the transport vehicle more reliable and smooth. On the other hand, it can also prevent the transport vehicle from colliding with the guide rail 61 or the guide platform 62, and prevent the wheel body 31 from escaping the guide rail 61, effectively ensuring that the transport vehicle moves strictly in the extension direction of the guide rail 61, ensuring the reliability and stability of the flow between different workstations.

[0058] In this embodiment, inspection stations and assembly stations are sequentially arranged along the extension direction of the guide rail 61. A transport vehicle can move along the extension direction of the guide rail 61 to transfer switches 9 between the assembly and inspection stations, thereby enabling inspection and assembly to be performed on a single production line without the need for transfer of switches 9.

[0059] Specifically, the leg frame 32 can be fixedly connected to the base frame 1 through a bolt assembly.

[0060] Specifically, the guide wheel 4 can be connected to the leg frame 32 through a bolt assembly.

[0061] In some other optional embodiments, the second side bracket 22 may also adopt the above-mentioned sliding structure and be slidably connected to the slide rail 12. Such a setting is equivalent to that the first side bracket 21 and the second side bracket 22 can both move relative to the base frame 1 and flexibly adjust their positions and spacing.

[0062] In some optional embodiments, a movable drive member is provided between the adjustment frame 11 and the base frame 1, and the movable drive member can realize automatic movement of the adjustment frame 11. For example, the movable drive member can be set as a cylinder, and can also be set as a linear servo module, an electric push rod and other components.

[0063] In this embodiment, the transport vehicle further includes a positioning pin 5, which is movably connected to the chassis 1 and is used to lock the transport vehicle. Specifically, the guide platform 62 is provided with positioning holes 621 at predetermined positions. Each positioning hole 621 can correspond to a target workstation. When the transport vehicle moves to the target workstation, the positioning pin 5 moves to a position directly opposite the positioning hole 621. At this time, the positioning pin 5 is controlled to be inserted into the positioning hole 621, which can effectively position the transport vehicle and ensure that the transport vehicle is securely positioned at the target workstation.

[0064] Optionally, the positioning pin 5 is configured as a spring pin.

[0065] In this embodiment, a handle 13 is further provided on the chassis 1. The provision of the handle 13 can facilitate the operator to push and pull the mobile transport vehicle, and the operation is convenient and labor-saving.

[0066] In this embodiment, a limit pedal 63 is provided on the guide rail 61, and a limit member 64 is provided on the guide platform 62. The limit pedal 63 is rotatably mounted on one side of the guide rail 61 and connected to the limit member 64. The limit pedal 63 is used to drive the limit member 64 to extend from the guide platform 62 to limit the position of the transport vehicle, or to drive the limit member 64 to retract from the guide platform 62 to release the limit on the transport vehicle. For example, when the limit pedal 63 is in its original position, the limit member 64 extends from the guide platform 62, and the limit member 64 is in a restricted state. When the transport vehicle moves to the target workstation, the stop member 64 prevents the transport vehicle from continuing to move, and the transport vehicle remains in the current workstation. When the transport vehicle needs to move to the next workstation, the operator steps on the limit pedal 63, which causes the limit member 64 to retract, releasing the restricted state and allowing the transport vehicle to continue to move along the track.

[0067] Optionally, the limit pedal 63 and the limit member 64 can be connected via a pneumatic cylinder. Specifically, the limit member 64 is located at the telescopic end of the cylinder. The limit pedal 63 and the cylinder are connected via a control unit, acting as a switch that triggers the cylinder's retraction. When the limit pedal 63 is depressed, the control unit sends a retraction signal to the cylinder, causing the cylinder's telescopic end to retract, which in turn drives the limit member 64 to retract, achieving telescopic control of the limit member 64.

[0068] In some alternative embodiments, the limit pedal 63 and the limit member 64 may be connected via a gear train. Specifically, the gear train includes a driving gear and a driven gear, both of which are rotatably connected to the guide platform 62 and mesh with each other. The pedal is connected to the driving gear, and the limit member 64 is connected to the driven gear. When the pedal is pressed, it swings downward, driving the driving gear to rotate, which in turn drives the meshed driven gear to rotate synchronously. This in turn drives the limit member 64 on the driven gear to swing inward from the guide platform 62 and retract into the guide platform 62, thereby controlling the extension and retraction of the limit member 64.

[0069] In addition, the provision of the guide platform 62 also provides sufficient standing space for on-site operators, and allows operators to move around the transport vehicle when the transport vehicle carrying the switch 9 moves to different workstations.

[0070] The switch production line further includes a ceiling support frame 7, which is positioned above the conveyor mechanism 6. A first receiving frame 71 and a second receiving frame 72 are provided along the guide rail 61. The first receiving frame 71 is used to hold assembly tools, and the second receiving frame 72 is used to hold testing equipment 73. Specifically, the assembly tools are used to assemble the switches 9, and the testing equipment 73 is used to test the performance of the assembled switches 9. Specifically, the first receiving frame 71 corresponds to the assembly station, and the second receiving frame 72 corresponds to the testing station. Both the ceiling support frame 7 and the receiving frame 71 are welded stainless steel frames. The switch production line can include assembly and testing stations, depending on the workstation's function. The assembly and testing stations can be spaced apart along the guide rail 61. Each assembly station is provided with a first receiving frame 71 on the ceiling support frame 7, and each testing station is provided with a second receiving frame 72 on the ceiling support frame 7. Specifically, the first accommodating frame 71 corresponding to the assembly station is used to place assembly tools for component assembly, such as a tool box, etc.; the second accommodating frame 72 corresponding to the inspection station is used to place the inspection equipment 73 and the power supply for electrical connection to the switch 9, etc.

[0071] For example, when the switch production line is set up in a factory building, the ceiling support frame 7 is fixed on the top of the factory building. Such a setting can make full use of the internal space of the factory building and does not occupy the walking space of the operators around the conveying mechanism 6.

[0072] Furthermore, a lighting element is provided on the ceiling support frame 7. The lighting element is used to provide lighting for different workstations to ensure that the operator has a reliable field of view during the operation.

[0073] Furthermore, a fan is also provided on the ceiling support frame 7. The setting of the fan can play a certain role in ventilation and heat dissipation for the switch production line, and improve the comfort of the operator during the operation process.

[0074] For example, Figure 5 Figure 2 shows a schematic layout diagram of a switch production line according to an alternative embodiment. In this embodiment, assembly stations and testing stations are arranged sequentially along the conveying direction of the conveyor mechanism 6. The assembly station can accommodate two tool carriers for simultaneous access and assembly of the switches 9, while the testing station can accommodate three tool carriers for simultaneous access and testing of the switches 9. Corresponding to the assembly stations, the first receiving frame 71 of the ceiling support frame 7 houses a fixture and toolbox. Corresponding to the testing stations, the second receiving frame 72 of the ceiling support frame 7 houses testing equipment 73.

[0075] For example, in actual use, the operator first uses a crane arm to lift the switch 9 to be tested onto the transport vehicle and fixes the switch 9 on the transport vehicle. The transport vehicle is then transported to the conveying mechanism 6, and the wheel body 31 of the transport vehicle enters the corresponding side guide rail 61, while the guide wheel 4 fits the side wall of the corresponding side guide platform 62. The operator then moves the transport vehicle to the assembly station. When it arrives at the assembly station, the limiter 64 of the assembly station limits the transport vehicle. The operator inserts the locating pin 5 into the corresponding limit hole of the guide platform 62 to ensure that the transport vehicle is securely held at the assembly station. The operator assembles the switch 9 product at the assembly station according to the assembly process. For example, the assembly station includes multiple sub-stations, each responsible for the assembly of different components. When the switch 9 is assembled, the operator pulls out the locating pin 5 and steps on the pedal to release the limiter 64. The operator then continues to move the transport vehicle to the inspection station. When it arrives at the inspection station, the limiter 64 of the inspection station limits the transport vehicle, and the operator inserts the positioning pin 5 into the corresponding limit hole of the guide platform 62 to keep the transport vehicle securely in the inspection station. At the inspection station, the operator connects the wires on the test equipment to the switch 9, conducts a comprehensive inspection of the assembled switch 9, and determines whether the switch 9 is qualified. If qualified, it is continuously transported downward through the conveying mechanism 6; if unqualified, the transport vehicle equipped with the unqualified switch is moved back to the assembly station for repair, and the inspection report is filled out and circulated along with the switch 9. For example, the inspection station includes multiple sub-stations, each equipped with different test equipment. When the switch is detected to be qualified, the operator pulls out the positioning pin 5 and steps on the pedal to release the limit member 64, and then moves the transport vehicle along the guide rail 61 to the downstream pressure test equipment 8 for the final test. After the test is completed, the switch 9 is moved to the boom with the transport vehicle for offline packaging of the switch 9.

[0076] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
