Description

Technical Field

[0001] The utility model relates to the technical field of assembly equipment, in particular to an assembly tool for a pole-mounted circuit breaker. Background Art

[0002] Pole-mounted circuit breakers are a type of equipment that mainly controls the operation or shutdown of electrical equipment in related power consumption areas. With the advancement of technology, various research levels and manufacturing technologies have made great progress. Pole-mounted circuit breakers are not only limited to medium-voltage power grids, but are also developing in the direction of high voltage, large capacity and safety.

[0003] In the actual production of pole-mounted circuit breakers, it is necessary to use appropriate tooling (in a broad sense, tooling includes the mechanism for fixing the parts to be assembled and the tools used to assemble the parts, etc.) to assemble the parts of the pole-mounted circuit breaker. After the corresponding parts of the pole-mounted circuit breaker are fixed on the adjustable fixing mechanism, the staff use tools such as electric wrenches to install the corresponding other parts and the fixed parts together to complete the assembly of the corresponding parts. In actual situations, some parts may also involve the use of grinding and polishing tools for grinding and polishing. Although the existing tooling used for fixing pole-mounted circuit breakers meets the actual production needs to a certain extent, due to the influence of its own structure and function, there is still room for technical improvement as follows. First: When grinding and polishing parts, the dust generated cannot be effectively treated, which will more or less cause some adverse effects on the health of the staff (installing dust treatment equipment specifically in the production area has the problems of high cost investment, large space occupation, and the overall equipment is not compact and beautiful). Second, it cannot provide hot or cold air for the workers. That is to say, if there is no cooling or heating equipment at the work site during assembly, the workers will feel uncomfortable because they are working in a relatively bad environment, which is not conducive to improving work efficiency (separate installation of heating and cooling mechanisms also has the problems of high cost, large space occupation, and the overall equipment is not compact and beautiful). Taking the above factors into consideration, it is particularly necessary to provide a tooling that not only has the function of fixing components, but also can effectively handle the dust generated during work and can provide cold or hot air for workers as needed. Utility Model Content

[0004] The utility model provides an assembly tool for a pole-mounted circuit breaker, which, under the joint action of relevant mechanisms, not only has the functions of fixing corresponding parts of the pole-mounted circuit breaker, facilitating the assembly of multiple parts together and grinding and polishing, but also can selectively process dust generated by grinding and polishing as needed, and blow out cold air or hot air from the upper end of the workbench, thereby bringing convenience to the staff, correspondingly improving the work efficiency, and effectively overcoming the disadvantages of the existing assembly tool for the pole-mounted circuit breaker as described in the background due to structural limitations.

The lower end of the electric vacuum pump M is installed on the fixing seat 104 on the right side of the middle of the lower end of the workbench through bolts, the air inlet pipe of the electric vacuum pump M is connected to one end of a three-way pipe through a thread, and the other two ends of the three-way pipe are connected to one end of the other two solenoid valves DC1 and DC2 through pipelines respectively, the other end of the second solenoid valve DC1 is connected to the exhaust pipe of the electric heating sub-mechanism through a thread, and the other end of the third solenoid valve DC2 is connected to the air inlet pipe of the dust filtering sub-mechanism through a thread; the power supply mechanism T1 and the power switch are installed on the circuit board in the component box 5, and the component box is installed on the front right end of the workbench.

[0017] Figure 1 , 2As shown in Figures 3 and 4, the convergence cover 4 is conical and the upper end is an open structure. The upper end of the convergence cover 4 is consistent in size with the upper end of the workbench 1. The solenoid valves DC, DC1, and DC2 are normally closed valve core solenoid valves; the shapes of the fixed block 2 and the movable block 3 are not limited to semicircular rings, but can also be any shape including rectangles. The electric heating sub-mechanism includes a hollow shell 6 and an electric heating plate RT (the connected wires are respectively led out through the openings at the upper and lower ends of the shell, and the openings are sealed with heat-resistant sealant). The two electric heating plates RT are respectively installed at the upper and lower ends of the shell 6 by bolt insulation. The middle of the left and right side ends of the shell 6 are respectively welded with an intake pipe and an exhaust pipe that are interconnected with the inside. The dust filtration sub-mechanism includes an intake pipe 7 and a filter bag 8. A connecting seat 9 is welded at the lower end of the intake pipe 7 (the middle opening at the upper end of the connecting seat 9 is welded to the lower end of the intake pipe 7), and the upper end of the filter bag 8 is tightly sealed and installed on the outer ends around the connecting seat 9. The electric vacuum pump M (existing mature technology) includes a capacitor-operated motor, a volute, and blades. The outer side of the right end of the volute and the outer side of the left end of the motor are sealed and installed together. The left end of the motor shaft enters the volute through the opening at the right end of the volute. The middle of the blade is welded to the left end of the shaft, and the outer diameter of the blade is smaller than the inner diameter of the volute. An exhaust pipe and an air intake pipe that are interconnected with the inside of the volute are welded to the outer side of the upper and lower ends of the volute. There are multiple vents 106 (to keep air flowing) in the middle of the left and right ends of the workbench.

[0018] Figure 1 , 2 As shown in Figure 3, the power input terminals 1 and 2 of the first power switch S4 are connected to the two poles of the AC 220V power supply via wires, and the power output terminals 3 and 4 of the power switch S4 are connected to the power input terminals of the two electric heating plates RT via wires. The power input terminal 1 of the power switch S3 is connected to one pole of the AC power supply via wires, the two power output terminals 2 and 3 of the power switch S3 are connected to the two ends of the running capacitor C of the motor M via wires, and the other end of the 220V AC power supply is connected to the main power input terminal of the motor M via wires (capacitor-operated motors are an extremely mature technology. By changing the wiring method at both ends of the capacitor, the motor shaft will rotate in different directions). The power input terminals 1 and 2 of the power supply mechanism T1 are connected to the two poles of the AC 220V power supply through wires, the power output terminals 3 and 4 of the power supply mechanism T1 are connected to the power input terminals 1 and 2 of the power switches S, S1, S2, and S5 through wires, and the power output terminals 3 and 4 of the power switches S, S1, and S2 are connected to the power input terminals of the first solenoid valve DC, the second solenoid valve DC1, and the third solenoid valve DC2 through wires. The power output terminals 3, 4 and 5, 6 of the fourth power switch S5 are connected to the positive and negative or negative and positive input terminals of the two sets of electric push rods M1 through wires.

[0019] Figure 1 , 2As shown in FIG. 3 , after the AC 220V power supply enters the power input terminal of the power supply mechanism T1, the power output terminal of the power supply mechanism T1 outputs a 24V power supply which enters the power input terminal of the power switches S, S1, S2, and S5. The staff puts the corresponding parts of the column-mounted circuit breaker that needs to be fixed between the movable block 3 and the fixed block 2. After the staff turns the handle of the power switch S5 to the left or right, the 1, 2 feet and the 3, 4 feet or the 5, 6 feet of the power switch S5 are connected respectively, so that the positive and negative or negative and positive power input ends of the two sets of electric push rods M are energized; after the positive and negative power input ends of the two sets of electric push rods M are energized, their movable columns push the movable block 3 to the left, so that the parts can be gradually clamped firmly between the fixed block and the movable block (after they are in place, the power switch S5 is turned off, and the staff installs other parts or polishes them on the parts); after the negative and positive power input ends of the two sets of electric push rods M are energized, their movable columns drive the movable block 3 to move to the right, so that the distance between the movable block 3 and the fixed block 2 will be increased, and the parts will no longer be clamped between the fixed block and the movable block (after they are in place, the power switch S5 is turned off, and the staff takes out the parts). When the staff needs to deal with dust when grinding or polishing parts, they turn on the power switches of the solenoid valves DC and DC2 (the electric valve cores of the solenoid valves DC and DC2 are opened), and turn the handle of the power switch S3 to the left, so that the 1 and 2 pins of the power switch S3 are connected (the power switch S3 is turned off when not in use), and one pole of the 220V power supply enters one end of the capacitor C. The shaft of the motor M drives the blades in the volute to rotate clockwise to generate a downward attraction. In this way, under the downward negative pressure suction of the electric vacuum pump, the dust generated by grinding or polishing will enter the convergence cover 4 through the several air holes 101 at the upper end of the workbench, and then enter the cloth bag 8. The air is discharged from the several openings on the surface of the cloth bag 8, and the dust is retained in the cloth bag 8. When the amount of dust is sufficient, the staff opens the movable door to take out the cloth bag to dump the dust, and then installs the cloth bag at the lower end of the solenoid valve DC2 for reuse.

[0020] Figure 1 , 2As shown in Figure 3, when no grinding or polishing process is performed (no dust is generated on the workbench), when the weather is hot, the staff can turn on the power switches of the solenoid valves DC and DC1 (the valve cores of the solenoid valves DC and DC1 are opened, and the valve core of the solenoid valve DC2 is closed), and turn the handle of the power switch S3 to the right, so that the 1 and 3 pins of the power switch S3 are connected (the power switch S3 is turned off when not in use), and one pole of the 220V power supply enters the other end of the capacitor C. The shaft of the motor M drives the blades in the volute to rotate counterclockwise to generate upward wind force. In this way, the electric vacuum pump will blow the flowing air upward through the several air holes 101 at the upper end of the workbench under the action of upward blowing, so as to blow and dissipate heat for the staff who process and install components on the workbench. When no grinding or polishing process is performed (no dust is generated on the workbench), when the weather is cold, the staff can turn on the power switches of the solenoid valves DC and DC1 (the solenoid valves DC and DC1 are electrically opened), turn on the power switch S4 of the electric heating plate RT (the electric heating plate RT is electrically heated), and turn the handle of the power switch S3 to the right, so that the 1 and 3 pins of the power switch S3 are connected (the power switch S3 is turned off when not in use), and one pole of the 220V power supply enters the other end of the capacitor C. The shaft of the motor M drives the blades in the volute to rotate counterclockwise to generate upward wind force. In this way, the electric vacuum fan will blow the hot air of the electric heating plate RT taken away by the flowing air upward through the several air holes 101 at the upper end of the workbench under the action of upward blowing, and blow hot air to the staff who are processing and installing components on the workbench. Through the joint action of all the above mechanisms, the novel device can fix the corresponding components of the pole-mounted circuit breaker, so that it is convenient to realize the functions of assembling multiple components together and grinding and polishing. Specifically, it can also reduce the adverse effects of dust on the health of workers. It can choose to blow cold air or hot air to the workers, provide a better working environment for the workers, and correspondingly improve the work efficiency, effectively overcoming the problems existing in the existing pole-mounted circuit breaker assembly tooling. Figure 3 Among them, the solenoid valves DC1, DC2, and DC are normally closed valve core solenoid valves with a power of 2W; the power supply mechanism T1 is an AC 220V to DC 24V power supply module; the motor M has a power of 1.2KW; the electric heating plate RT is a PTC constant temperature 50℃ electric heating plate with a power of 1.5KW; the capacity of the capacitor C is 14μF; the electric push rod M1 is a reciprocating electric telescopic rod with a power of 80W.
