Description

technical field [0001] The invention belongs to the technical field of switch cabinets, and in particular relates to a handcart circuit breaker transfer vehicle and a method thereof. Background technique [0002] In the power grid industry, the handcart circuit breaker is an important device in the high-voltage switchgear; during the installation and maintenance of the handcart circuit breaker, it is necessary to push or pull the handcart circuit breaker out of the switchgear. [0003] At present, the handcart transfer vehicle used in substations has no guiding structure between the lock tongue used for fixing the transfer vehicle and the switch cabinet and the lock groove of the cabinet body, resulting in that the lock tongue cannot be smoothly inserted into the cabinet during the process of pushing the transfer vehicle to join the switch cabinet. In the body lock slot; there is no height adjustment mechanism, so that the staff cannot adjust the height of the handcart trans...

Problems solved by technology

[0003] At present, the handcart transfer vehicle used in substations has no guiding structure between the lock tongue used for fixing the transfer vehicle and the switch cabinet and the lock groove of the cabinet body, resulting in that the lock tongue cannot be smoothly inserted into the cabinet during the process of pushing the transfer vehicle to join the switch cabinet. In the body lock slot; there is no height adjustment mechanism, so that the staff cannot adjust the height of the handcart transfer vehicle according to the height requirements of different switch cabinets, and it takes a lot of effort to push and pull, causing great inconvenience; and the existing The four wheels of the transfer car are universal wheels, it is difficult to control the direction accurately
