Description

Technical Field

[0001] The utility model relates to a circuit breaker assembly tool in the technical field of circuit breaker assembly. Background Art

[0002] A circuit breaker is a switch device that can close, carry and break the current under normal circuit conditions and close, carry and break the current under abnormal circuit conditions within a specified time. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are seriously overloaded or short-circuited or undervoltage. Its function is equivalent to the combination of a fuse switch and an overheating relay. Some circuit breakers are large in size, have many components assembled inside, and are heavy in weight. Therefore, when assembling them, they often need to be lifted and turned to a suitable angle by an overhead crane, and then put down to assemble the components. This is time-consuming and laborious, and when the circuit breaker is placed back on the assembly workbench, it is easy to bump and damage the components. Utility Model Content

[0003] The utility model aims to provide a novel gas-filled cabinet circuit breaker assembly tool, which can directly suspend the circuit breaker and provide sufficient space up and down, front and back, so as to facilitate the assembly of components and avoid collision of the circuit breaker, thereby avoiding damage to the components.

[0004] To achieve the above purpose, the utility model provides a novel inflatable cabinet circuit breaker assembly tool, including a mounting structure, a sliding mechanism is arranged on the mounting structure, the sliding mechanism is connected to the assembly structure, and the assembly structure is equipped with an anti-drooping mechanism and a locking mechanism.

[0005] Compared with the prior art, the beneficial effect of the utility model is that the assembly tooling as a whole is fixed to the lifting mechanism of the stacker by the installation structure, and then the frame of the circuit breaker is fixedly connected to the assembly structure, and the frame of the circuit breaker is supported by the anti-drooping mechanism, so as to play an auxiliary support role for the circuit breaker, and the locking mechanism can lock the circuit breaker in the horizontal direction to prevent it from moving back and forth on the sliding mechanism. After the circuit breaker is assembled, it is pushed directly to the inflatable cabinet by the stacker, and the position of the circuit breaker and the inflatable cabinet is fine-tuned by unlocking the locking mechanism, so as to facilitate pushing it into the inflatable cabinet for installation. The circuit breaker can be directly suspended and placed in the air, with sufficient space up and down, front and back, which is convenient for the assembly of components, and the circuit breaker will not be bumped, thereby avoiding damage to the components.

[0006] As a further improvement of the utility model, the mounting structure includes a mounting plate, a pair of fixing plates are symmetrically arranged on both sides of the back side of the mounting plate, fixing screw holes are opened on the fixing plates, and the fixing screw holes are equipped with fixing bolts.

[0007] In this way, holes are opened on both sides of the lifting mechanism of the stacker, so that the fixing plate can be connected to the lifting mechanism by bolts. In this way, the assembly tool can be raised and lowered by the stacker, thereby realizing the lifting and lowering of the circuit breaker.

[0008] As a further improvement of the utility model, the sliding mechanism includes an upper slide rail and a lower slide rail. The upper slide rail is arranged at the upper end of the front side of the back plate, and the lower slide rail is arranged at the lower end of the front side of the back plate. The back side of the back plate is fixedly connected to the front side of the mounting plate. The upper slide rail is equipped with a pair of upper sliders, and the lower slide rail is equipped with a pair of lower sliders. Limiting blocks are arranged at both ends of the upper slide rail and the lower slide rail.

[0009] In this way, the upper slider moves back and forth along the upper slide rail, and the lower slider moves back and forth along the lower slide rail, so that the assembly structure moves the circuit breaker back and forth along the upper slide rail and the lower slide rail to fine-tune the position of the circuit breaker so that the circuit breaker can match the installation position of the inflatable cabinet in the horizontal direction.

[0010] As a further improvement of the utility model, the assembly structure includes a pair of assembly frames, the upper ends of the back sides of the pair of assembly frames are respectively connected to a pair of upper sliders, the lower ends of the back sides of the pair of assembly frames are respectively connected to a pair of lower sliders, and a plurality of assembly holes are opened on the front side of the assembly frames, and the assembly holes are equipped with assembly bolts.

[0011] In this way, the frame of the circuit breaker is fixedly connected to the front of the assembly rack by bolts. Since components will be assembled on both the front and back sides of the circuit breaker frame, and there is sufficient space from the front to the back of the assembly rack, it is convenient to assemble components on the front and back of the circuit breaker.

[0012] As a further improvement of the utility model, there is an anti-drooping mechanism including a mounting seat, which is arranged at the upper front end of the assembly frame, the mounting seat is connected to the L-shaped hook plate through a pin shaft, and the lower front end of the assembly frame is equipped with a lower supporting block, which cooperates with the hook plate.

[0013] In this way, the lower end of the circuit breaker frame is placed on the top of the lower supporting block, and the circuit breaker is given an upward force through the lower supporting block. After the L-shaped hook plate flips around the pin shaft, its short side just hooks and presses the upper end of the circuit breaker frame, thereby cooperating with the lower supporting block to further ensure that the circuit breaker will not sag on the assembly frame due to its own weight.

[0014] As a further improvement of the utility model, the locking mechanism includes a push-pull quick clamp, which is fixedly connected to the lower end of the rear side of the assembly frame. The end of the telescopic rod of the push-pull quick clamp is provided with a rubber pressure block, which is directly opposite to the lower part of the mounting plate.

[0015] In this way, by using the push-pull quick clamp, after the end of the telescopic rod is extended, the rubber pressure block firmly contacts the lower part of the mounting plate, so that the assembly frame cannot move back and forth along the upper slide rail and the lower slide rail, ensuring that the circuit breaker is stable in place during assembly. When the circuit breaker needs to be assembled into the gas-filled cabinet, the push-pull quick clamp is released to retract the end of the telescopic rod, making it convenient to adjust the horizontal position of the assembly frame so that the installation positions of the circuit breaker and the gas-filled cabinet are horizontally aligned.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-3 A novel inflatable cabinet circuit breaker assembly tool is shown, including a mounting structure, a sliding mechanism is arranged on the mounting structure, the sliding mechanism is connected to the assembly structure, and the assembly structure is equipped with an anti-drooping mechanism and a locking mechanism. The mounting structure includes a mounting plate 7, a pair of fixing plates 4 are symmetrically arranged on both sides of the back of the mounting plate 7, and the fixing plates 4 are provided with fixing screw holes 15, and the fixing screw holes 15 are equipped with fixing bolts.

[0022] The sliding mechanism includes an upper slide rail 3 and a lower slide rail 11. The upper slide rail 3 is arranged at the upper end of the front face of the back plate 5, and the lower slide rail 11 is arranged at the lower end of the front face of the back plate 5. The back face of the back plate 5 is fixedly connected to the front face of the mounting plate 7. The upper slide rail 3 is equipped with a pair of upper sliders 2, and the lower slide rail 11 is equipped with a pair of lower sliders 10. Limit blocks are arranged at both ends of the upper slide rail 3 and the lower slide rail 11.

[0023] The assembly structure includes a pair of assembly frames 6, the upper ends of the back of the pair of assembly frames 6 are respectively connected to a pair of upper sliders 2, the lower ends of the back of the pair of assembly frames 6 are respectively connected to a pair of lower sliders 10, and a plurality of assembly holes 14 are provided on the front of the assembly frame 6, and the assembly holes 14 are equipped with assembly bolts. There is an anti-drooping mechanism including a mounting seat 1, which is arranged at the upper front end of the assembly frame 6, and the mounting seat 1 is connected to the L-shaped hook plate 8 through a pin shaft, and the lower front end of the assembly frame 6 is equipped with a lower support block 9, and the lower support block 9 cooperates with the hook plate 8.

[0024] The locking mechanism includes a push-pull quick clamp 12, which is fixedly connected to the lower end of the rear side of the assembly frame 6. The end of the telescopic rod of the push-pull quick clamp 12 is provided with a rubber pressure block 13, which is directly opposite to the lower part of the mounting plate 7.

[0025] In the utility model, holes are opened on both sides of the lifting mechanism of the stacker, so that the fixing plate 4 can be connected to the lifting mechanism by bolts, and the assembly tool can be lifted up and down by the stacker, thereby realizing the lifting of the circuit breaker 16 during the assembly process. The stacker can put down a lot more circuit breakers 16 in the workshop than the overhead crane, and the operation is more convenient, so that multiple circuit breakers 16 can be assembled at the same time.

[0026] The frame 17 of the circuit breaker 16 is fixedly connected to the front of the assembly frame 6 by bolts, so that the circuit breaker 16 is fixed to the assembly tool. The lower end of the frame 17 of the circuit breaker 16 is placed on the top of the lower support block 9, and the circuit breaker 16 is given an upward force through the lower support block 9. After the L-shaped hook plate 8 is turned around the pin, its short side just hooks and presses the upper end of the frame 17 of the circuit breaker 16, so as to cooperate with the lower support block 9 to further ensure that the circuit breaker 16 will not sag on the assembly frame 6 due to its own weight.

[0027] After the frame 17 of the circuit breaker 16 is fixedly connected to the assembly rack 6, the push-pull quick clamp 12 is manually operated to extend the end of its telescopic rod, and the rubber pressure block 13 firmly contacts the lower part of the mounting plate 7, so that the assembly rack 6 cannot move back and forth along the upper slide rail 3 and the lower slide rail 11, ensuring that the circuit breaker 16 is stable in place during the assembly process.

[0028] When assembling components of the circuit breaker 16, the frame 17 of the circuit breaker 16 is at the front end of the assembly frame 6, so there is still sufficient space behind the frame 17, so that it is convenient to install the components in place, and the circuit breaker 16 can be lifted or lowered as a whole by the lifting mechanism of the forklift, so as to facilitate the assembly of components at its bottom or top.

[0029] After the circuit breaker 16 is assembled, the stacker can be pushed directly in front of the inflatable cabinet, and the installation position of the circuit breaker 16 on the inflatable cabinet can be clearly shown with a marking line. Then, the vertical height of the circuit breaker 16 and the installation position on the inflatable cabinet can be adjusted by the stacker lifting mechanism, and then the push-pull quick clamp 12 can be operated to retract the telescopic rod. In this way, the horizontal position of the circuit breaker 16 and the inflatable cabinet can be fine-tuned by the upper slider 2 and the lower slider 10. After the vertical and horizontal positions are adjusted, the push-pull quick clamp 12 is manually operated again to extend the end of the telescopic rod, and the rubber pressure block 13 is firmly in contact with the lower part of the mounting plate 7, thereby avoiding horizontal displacement of the circuit breaker 16 when the circuit breaker 16 is sent into the inflatable cabinet.

[0030] After the circuit breaker 16 is pushed into the designated installation position of the gas cabinet by the forklift, the frame 17 of the circuit breaker 16 is fixedly connected to the gas cabinet with bolts, and then the bolts on the frame 17 of the circuit breaker 16 and the assembly frame 6 are removed, the hook plate 8 is flipped in the opposite direction, and the forklift is pulled backward, so that the circuit breaker 16 is separated from the assembly frame 6. In this way, the circuit breaker 16 is successfully installed in the gas cabinet. Since the gas cabinet is only an empty cabinet at this time, there will be no problem of collision with other components when the circuit breaker 16 is pushed into the gas cabinet.

[0031] The utility model makes full use of the stacker in the workshop to realize the suspended assembly of the circuit breaker 16, which makes the assembly more convenient. After the circuit breaker 16 is assembled, the stacker can be directly pushed to transport it to the gas-filled cabinet. The horizontal and vertical deviations between the circuit breaker 16 and its installation position in the gas-filled cabinet are adjusted by the stacker and the sliding mechanism, so that the circuit breaker 16 can be finally aligned with the installation position, and then it can be directly pushed into the gas-filled cabinet for installation and fixation, which saves time and effort, is more convenient and quick to operate, and avoids bumps caused by using an overhead crane.
