Description

TECHNICAL FIELD

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

[0002] High-voltage circuit breakers are electrical appliances with contacts, and the purpose of opening and closing the circuit is achieved by the opening and closing of the contacts. Therefore, it must rely on a certain mechanical operating system to complete. The mechanical operating device outside the circuit breaker body is called an operating mechanism, and the transmission part between the operating mechanism and the movable contact of the circuit breaker is called a transmission mechanism and a 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 relatively large. This increases the difficulty of installing the main spring. If manual operation is performed, not only the labor intensity is increased, but also the operator is easily injured. In order to improve efficiency and safety, a tool for assembling the main spring is needed.

[0004] A plastic shell circuit breaker mechanism tension spring assembly device is disclosed in Chinese Patent No. CN202042428U, which comprises 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 can slide up and down. The inner surface of the rear guide block is inclined, and the middle part has a boss in contact with the rack. The inner surfaces of the upper guide block and the lower guide block are also inclined, and the inclination is the same as that of the inner surface of the rear guide block. One end of the handle is fixed to 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 lower outer side of the rack.

[0005] According to the related technology in the above, in the prior art, the gear is rotated and the rack is moved by operating the handle to stretch the tension spring. The cooperation of the gear and the rack requires the operator to continuously apply force throughout the process. The longer the tension spring is stretched, the more force is required. At the same time, the rack rotates when it rises. At this time, the top end of the rack abuts against the inclined surface of the upper guide block. During the descending process, the rack gradually returns to the initial angle under the action of the tension spring. At this time, the operator needs to operate the hook plate to move the top end of the tension spring in order to realize the assembly of the tension spring. Therefore, the operator is in close contact with the tension spring, which has safety hazards and reduces the operation efficiency of the tension spring assembly device.
