[0002] During the inspection of the ladder car of the rigid contact network equipment of the rail transit power supply, due to the high height of the ladder car, the operating personnel need to hang the safety belt on the rigid contact network above to carry out inspection work to prevent people from falling; and the rigid contact network is a strip-distributed equipment, and the distribution range covers all the lines of electric passenger cars. The spacing between the hanging points of each rigid contact network is 6-8 meters, and the overall number of hanging points is extremely large. During the inspection of the ladder car, the operating personnel are required to hang and remove the safety belt at each hanging point, which consumes a long working time and reduces the net working time; at the same time, while the ladder car is moving, the safety belt cannot be hung on the rigid contact network, and the inspection workers on the ladder car cannot continue to be effectively protected by the safety belt, and there is a risk of injury other than the operating personnel.

[0003] At present, the contact network bus body is used as the hanging point for the safety belt during the operation process. The ladder truck operator moves to the hanging point during the inspection of the equipment, stops the ladder truck, and wraps the safety belt upwards to the bus to perform the inspection operation. After the operation, the safety belt is removed, and the safety belt is re-installed after the ladder truck moves and passes the hanging point, which wastes working time. In addition, there is a risk of falling from a height during the installation and removal of the safety belt.

[0004] Based on the above situation, a rigid contact network safety belt hanging tooling was invented. Through this technical means, the risk of personal injury in rigid contact network inspection operations can be well solved, and the operation efficiency and working time utilization can be improved.
