A bridge detecting vehicle with two foldable arms, including: a vehicle body, slewing mechanisms, horizontal and vertical arms and telescopic arms. One end of the two horizontal arms is respectively arranged on the slewing mechanisms, and the other end of the two horizontal arms is respectively connected to the two horizontal arms. A crossed arm is provided between the two horizontal arms. The two vertical arms are respectively connected to the two horizontal arms via ball joints. A detecting device is respectively provided at rear ends of the two telescopic arms.

Bridge detecting vehicle with two foldable arms

The invention discloses a multi-bar linkage mechanism based conveyor, comprising a gantry system, a multi-bar linkage mechanism based conveyor boom, a boom support, a two-drum winch, a roller unit and an automatic control system. The gantry system, the two-drum winch and the boom support are mounted on a deck of a hull. The conveyor boom is formed of multi-bar linkage mechanisms, the movement of which can be changed. Rollers are mounted on the conveyor boom. The rear segment of the conveyor boom is articulated with the boom support. The two-drum winch is connected to the multi-bar linkage mechanism based conveyor boom via a steel wire rope and by a set of gantry pulleys. A hydraulic device and a control device are arranged between adjacent multi-bar linkage mechanisms. A tension sensor is arranged at an end of the steel wire rope. The whole conveyor is controlled by the automatic control system.

Multi-bar linkage mechanism based conveyor

The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.
