Description

Technical Field

[0001] This utility model relates to the field of circuit breaker manufacturing technology, and specifically to a pillar-type circuit breaker lifting and assembly machine. Background Technology

[0002] Circuit breakers are widely used in industrial production and daily life, and their main function is to close and disconnect circuits. Post-mounted circuit breakers typically employ a three-phase post-mounted structure, with each post containing an arc-extinguishing chamber and an insulating cylinder. Patent application CN108389752A discloses a post-mounted circuit breaker, including a support and an insulating cylinder mounted on the support. An arc-extinguishing chamber is installed inside the insulating cylinder, and one end of the arc-extinguishing chamber is connected to a conductive rod extending horizontally from the insulating cylinder. A current transformer is sleeved on the outside of the conductive rod, and a support assembly is provided between the support and the current transformer to support the current transformer vertically.

[0003] After the components of a post-mounted circuit breaker are assembled, inspected, and tested on the production line, the finished product is obtained. Typically, the support (or enclosure) of the post-mounted circuit breaker is first placed on a handcart. Then, workers push the handcart sequentially to the designated process position, assembling specific components onto the support. The handcart then moves to the next installation process position, in an assembly line operation. For example, insulating cylinders, conductive rods, current transformers, and support components are assembled onto the support in sequence.

[0004] like Figures 1 to 3 As shown, a traditional handcart is used. The support 101 of the pillar-type circuit breaker is fixed to the top of the cart frame 10 using bolts 102. The bottom of the frame has casters. The cart carries the support and moves it sequentially to the designated process position. After assembly, the bolts are unlocked to remove the pillar-type circuit breaker product from the handcart. Since the height of the support on the frame is fixed, but different workers are assigned to different process positions, and the heights of the workers vary, when the same handcart passes by different workers, some taller workers need to bend over to assemble parts on the support, while shorter workers need to stand on tiptoe or on a stool to assemble parts on the support. This leads to worker fatigue and reduces assembly efficiency.

[0005] Therefore, in order to adjust the support height on the chassis to accommodate different workers' heights, there is an urgent need in this technical field for a support-type circuit breaker lifting assembly machine. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a support-type circuit breaker lifting and assembly machine.

[0007] The technical solution adopted by this utility model is: a pillar-type circuit breaker lifting and assembly machine, comprising:

[0008] Assembly table, lifting drive device, base, first limit rod, second limit rod, first telescopic drive device, second telescopic drive device, distance sensor, operation panel, standing platform;

[0009] The top surface of the assembly platform has a left baffle and a right baffle, and the space between the left baffle and the right baffle is a frame channel. The first limiting rod is located at the exit of the frame channel, and the second limiting rod is located at the entrance of the frame channel. The first limiting rod is connected to the assembly platform through the first telescopic drive device, and the second limiting rod is connected to the assembly platform through the second telescopic drive device.

[0010] The assembly table and the base are connected by the lifting drive device, and the distance sensor is installed on the base to detect the distance between the assembly table and the base;

[0011] The standing platform is located to the left or right of the assembly platform. The operation panel is fixedly installed on the top surface of the standing platform. The operation panel is electrically connected to the distance sensor, the lifting drive device, the first telescopic drive device, and the second telescopic drive device. The operation panel has buttons and a display screen.

[0012] Furthermore, it also includes: a card, which is filled in with the name and assembly height, and the card is connected to the hanging hole of the operation panel via a hook.

[0013] Furthermore, it also includes: a production line floor, wherein the production line floor is provided with a recess, and the base is fixedly installed within the recess.

[0014] Furthermore, the ranging sensor is a laser ranging sensor, an infrared ranging sensor, or an ultrasonic ranging sensor.

[0015] Furthermore, both the first telescopic drive device and the second telescopic drive device are telescopic cylinders.

[0016] Furthermore, the lifting drive device is a scissor lift device.

[0017] Compared with the prior art, the beneficial effects or advantages of this utility model are as follows:

[0018] The chassis is pushed to the first process position, and the chassis, carrying the support, enters the chassis passage of the assembly table. The worker, positioned on the stand, uses the control panel to extend the first and second limit rods sequentially to prevent the chassis from leaving the chassis passage. The worker then controls the lifting drive via the control panel to change the height of the assembly table, thereby adjusting the support height on the chassis to accommodate different assembly workers' heights. When the worker deems the height of the chassis and support to be suitable for assembly, the lifting drive stops via the control panel. A distance sensor detects the distance between the assembly table and the base and sends it to the display screen on the control panel. The worker records this distance so that the height can be quickly adjusted to the appropriate assembly height when the next chassis arrives at the process position. This helps reduce worker fatigue and improve assembly efficiency. Attached Figure Description

Detailed Implementation

[0028] This utility model embodiment provides a pillar-type circuit breaker lifting and assembly machine. The overall technical concept is as follows:

[0029] The support of the pillar-type circuit breaker is bolted to the frame of a handcart. The handcart carries the support and moves it sequentially to the designated process position. Each process position has a lifting assembly machine for the pillar-type circuit breaker of this invention. Initially, the frame channel of the assembly table is aligned with the production line floor. The worker pushes the frame and support into the frame channel. The worker, standing on the platform, controls the first and second telescopic drive devices via the operation panel to extend the first and second limit rods, preventing the frame from leaving the assembly table. Then, the worker controls the lifting drive device via the operation panel to change the height of the assembly table, thereby adjusting the support height on the frame to accommodate different assembly personnel. When the worker feels that the height of the frame and support is suitable for assembly, the lifting drive device is stopped via the operation panel. A distance sensor detects the distance between the assembly table and the base and feeds it back to the display screen of the operation panel. The worker can see the suitable assembly table height for their assembly work on the display screen, and can quickly adjust it when the next frame arrives at the process position.

[0030] 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.

[0031] See Figures 1 to 7 The preferred embodiment of this utility model.

[0032] A post-mounted circuit breaker lifting and assembly machine, comprising:

[0033] Assembly table 1, lifting drive device 2, base 3, first limit rod 4, second limit rod 5, first telescopic drive device 41, second telescopic drive device 51, distance sensor 6, operation panel 7, standing platform 8.

[0034] The top surface of the assembly platform 1 has a left baffle 11 and a right baffle 12. The space between the left baffle 11 and the right baffle 12 is a frame channel 13. The first limiting rod 4 is located at the outlet of the frame channel 13, and the second limiting rod 5 is located at the entrance of the frame channel 13. The first limiting rod 4 is connected to the assembly platform 1 through the first telescopic drive device 41, and the second limiting rod 5 is connected to the assembly platform 1 through the second telescopic drive device 51.

[0035] The assembly platform 1 and the base 3 are connected by the lifting drive device 2, and the distance sensor 6 is installed on the base 3 to detect the distance between the assembly platform 1 and the base 3.

[0036] The standing platform 8 is located to the left or right of the assembly platform 1. The operation panel 7 is fixedly installed on the top surface of the standing platform 8. The operation panel 7 is electrically connected to the distance sensor 6, the lifting drive device 2, the first telescopic drive device 41, and the second telescopic drive device 51. The operation panel 7 has buttons and a display screen.

[0037] The beneficial effects or advantages of this utility model are as follows: The frame 10 is pushed to a process position, and the frame 10 carrying the support 101 enters the frame channel 13 of the assembly table 1. The worker, located on the standing platform 8, uses the operation panel 7 to extend the first limit rod 4 and the second limit rod 5 to prevent the frame 10 from leaving the frame channel 13. Then, the worker controls the lifting drive device 2 through the operation panel 7 to change the height of the assembly table 1, thereby adjusting the height of the support 101 on the frame 10 to accommodate the height of different assembly workers. When the worker feels that the height of the frame 10 and the support 101 is at a suitable assembly height, the worker stops the lifting drive device 2 through the operation panel 7. The distance sensor 6 detects the distance between the assembly table 1 and the base 3 and feeds it back to the display screen of the operation panel 7. The worker records this distance so that when the next frame 10 arrives at the process position, it can be quickly adjusted to a suitable assembly height. This helps to reduce worker fatigue and improve assembly efficiency.

[0038] In this embodiment, there are two first limiting rods 4 at the exit of the frame channel 13, and the two first limiting rods 4 are slidably connected to the left baffle 11 and the right baffle 12 respectively; there are two second limiting rods 5 at the entrance of the frame channel 13, and the two second limiting rods 5 are slidably connected to the left baffle 11 and the right baffle 12 respectively.

[0039] The operation panel 7 includes a power button, a first button for controlling the first telescopic drive device 41, a second button for controlling the second telescopic drive device 51, an up button for controlling the upward movement of the lifting drive device 2, and a down button for controlling the downward movement of the lifting drive device 2; it also includes buttons for other functions. The operation panel 7 has a built-in MCU and memory. The distance sensor 6 detects the distance between the assembly table 1 and the base 3 and feeds it back to the display screen of the operation panel 7. When the operator sees the appropriate height for their assembly work on the display screen, they can save this appropriate height to the memory using the setting button on the operation panel 7. After the next frame 10 enters the current process position of the assembly table 1, the operator can use the shortcut buttons on the operation panel 7 to have the MCU control the lifting drive device 2 to adjust the height of the assembly table 1 to the height saved in the memory.

[0040] Furthermore, it also includes: a card 71, which is filled in with the name and assembly height, and the card 71 is connected to the hanging hole of the operation panel 7 via a hook.

[0041] The beneficial effects of this technical solution are as follows: The name on card 71 is the name of the worker at the current work position, and the assembly height is the height suitable for the worker at the current work position to perform the assembly work. For two-shift or three-shift operations, when two or more workers use the support-type circuit breaker lifting assembly machine of this utility model separately, and the workers have different heights and suitable assembly heights, the workers carrying card 71 can easily remember and confirm who is using the support-type circuit breaker lifting assembly machine at any given time.

[0042] Furthermore, it also includes: a production line floor 9, wherein the production line floor 9 is provided with a recess 91, and the base 3 is fixedly disposed within the recess 91.

[0043] The beneficial effects of this technical solution are: it facilitates the alignment of the chassis channel 13 of the assembly table 1 with the production line floor 9, and helps the assembly table 1 to move up and down.

[0044] Furthermore, the ranging sensor 6 is a laser ranging sensor 6, an infrared ranging sensor 6, or an ultrasonic ranging sensor 6. This is a preferred product structure of this utility model.

[0045] Furthermore, both the first telescopic drive device 41 and the second telescopic drive device 51 are telescopic cylinders.

[0046] When the frame 10 enters the assembly table 1, the first telescopic drive device 41 and the second telescopic drive device 51 respectively extend the first limit rod 4 and the second limit rod 5; after the current assembly process is completed, the first telescopic drive device 41 and the second telescopic drive device 51 respectively retract the first limit rod 4 and the second limit rod 5, and the frame 10 is pushed out of the assembly table 1.

[0047] Furthermore, the lifting drive device 2 is a scissor lift device.

[0048] For information on scissor lift devices, please refer to the patent document CN209906269U, entitled "A Scissor Lift Mechanism".

[0049] The working method of this utility model is as follows: Each process position in the assembly line of the support-type circuit breaker has a lifting assembly machine for the support-type circuit breaker according to this utility model. First, the support 101 of the support-type circuit breaker is fixed to the frame 10 of the handcart using bolts 102. The handcart carries the support 101 and moves sequentially to the designated process position. Multiple handcarts advance in sequence. At one process position, the frame channel 13 of the initial assembly table 1 is aligned with the production line floor 9. The worker pushes the frame 10 of the handcart into the frame channel 13 of the assembly table 1, and then controls the first telescopic drive device 41 and the second telescopic drive device 51 through the operation panel 7. The first limiting rod 4 and the second limiting rod 5 extend to prevent the frame 10 from leaving the assembly table 1. Then, the lifting drive device 2 is controlled by the operation panel 7 to change the height of the assembly table 1 so that the height of the frame 10 and the support 101 is at a suitable assembly height. The workers then assemble the parts onto the support 101, effectively avoiding the workers having to bend over or stand on tiptoe to assemble. After completing the assembly of the current process, the workers use the operation panel 7 to return the assembly table 1 to its initial state, and then use the operation panel 7 to retract the first limiting rod 4 and the second limiting rod 5, pushing the trolley that has completed the assembly of the current process out of the frame channel 13.
