Description

Technical Field

[0001] The present application relates to the technical field of operating mechanism assembly, and in particular to a tool for assembling a main spring inside an operating mechanism. Background Art

[0002] High-voltage circuit breakers are electrical appliances with contacts. The purpose of opening and closing the circuit is achieved by opening and closing the contacts. Therefore, a certain mechanical operating system must be relied upon to complete the task. The mechanical operating device outside the circuit breaker body is called the operating mechanism, and the transmission part connecting the operating mechanism and the moving contact of the circuit breaker is called the transmission mechanism and the lifting mechanism.

[0003] The internal main spring of the operating mechanism is a tension spring. In order to ensure the smooth operation of the operating mechanism, the spring force of the main spring needs to be set larger, which increases the difficulty of installing the main spring. If it is operated manually, it will not only increase the labor intensity but also be easy to get injured. In order to improve efficiency and safety, a tooling for assembling the main spring is needed.

[0004] A Chinese patent with announcement number CN202042428U discloses a tension spring assembly device for a molded case circuit breaker mechanism, which includes a gear box, a gear, a rack, a handle, a rear guide block, an upper guide block, a lower guide block, and a hook plate. The gear, the rear guide block, the upper guide block, and the lower guide block are fixed in the gear box, the gear is fixed between the upper guide block and the lower guide block, the rack is clamped between the rear guide block and the gear, and the rack can slide up and down; the inner surface of the rear guide block is an inclined surface, and a boss is provided in the middle to contact the rack. The inner surfaces of the upper guide block and the lower guide block are also inclined surfaces, and the inclination is the same as that of the inner surface of the rear guide block; one end of the handle is fixed on the gear shaft, and the other end is exposed outside the gear box and can rotate freely around the gear shaft; the hook plate is fixed to the outer side of the lower part of the rack.

[0005] With regard to the above-mentioned related technologies, in the prior art, the gear is rotated and the rack is moved by operating the handle to stretch the tension spring, and the rack is rotated by relying on the cooperation between the upper guide block and the rear guide block to make the tension spring clamped on the mechanism bracket. However, the cooperation between the gear and the rack requires the operator to apply force continuously throughout the whole process, and the longer the tension spring is stretched, the more effort it requires. At the same time, the rack rotates when it rises, and the top of the rack is pressed against the inclined surface of the upper guide block. During the descent, under the force of the tension spring, the rack will gradually return to the initial angle. At this time, the operator is also required to operate the hook plate to move the top of the tension spring to realize the assembly of the tension spring. In this way, the operator is in close contact with the tension spring, which poses a safety hazard and reduces the operating efficiency of the tension spring assembly device.
