Abstract

The invention relates to a device capable of reducing impact safety accidents of an engineering electric cart. The device comprises an impact circuit breaker and a release circuit breaker which are connected in series in a control loop for controlling start and stop of an electric cart, and a circuit break braking device electrically connected to the control loop; the impact circuit breaker comprises a travel switch and is arranged on a vehicle head, and an impact piece is arranged in front of the vehicle head; the release circuit breaker comprises a magnetic attraction switch, and the magnetic attraction switch is arranged at a handlebar. The circuit break brake device comprises a circuit break sensor, an electric instantaneous brake device and a standby power supply, the circuit break sensor is electrically connected to the control loop and arranged on the vehicle body, the electric instantaneous brake device is arranged on the driving wheel and is in signal connection with the circuit break sensor, and the standby power supply is electrically connected with the electric instantaneous brake device; hidden dangers caused by misoperation of the electric vehicle can be reduced.

Description

technical field [0001] The invention relates to the technical field of engineering carts, in particular to a device capable of reducing collision safety accidents of engineering electric carts. Background technique [0002] Nowadays, electric tools are widely used in construction, which greatly saves manpower and speeds up the construction progress. The transportation efficiency of engineering electric carts is three times that of ordinary human carts, and the cost can be saved by about half. However, due to misoperation of electric carts, accidents of electric carts hitting construction elevator doors frequently occur. Relevant regions have also issued documents prohibiting electric engineering carts. [0003] The invention aims at refitting the existing electric trolley so as to reduce the hidden dangers even caused by wrong operation of the electric cart. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned technic...
