Problems solved by technology

[0003] The existing bridge transport vehicle is prone to torque generated by eccentric force when turning, which will cause the prefabricated beam to be unstable or overturned, and the overturning accident of the prefabricated beam on the beam transport vehicle will occur. The bending and shear strength is not enough, which may cause the beam transport vehicle When passing through, the wing plate breaks and causes the problem of rollover

Abstract

The invention discloses a bridge transport vehicle, which mainly relates to the technical field of road and bridge construction equipment, and comprises a tractor, a semitrailer and a fast gun carrier, a movable turntable is arranged on the semitrailer, a rotatable hydraulic telescopic device is arranged above a transport vehicle body, and a bridge bearing base is arranged above the rotatable hydraulic telescopic device; the balance detection device is arranged in the bridge bearing base, the sliding rail is installed on the upper portion in the bridge bearing base, the gravity detection device is installed in the sliding rail, the bridge fixing devices are arranged at the two ends of the bridge bearing base, the walking trolley is arranged on the rail, and the rotating mechanism is arranged on the walking trolley. One end of the hydraulic control device is hinged to the longitudinal moving platform through a rotating frame, the other end of the hydraulic control device is hinged to the longitudinal moving platform through a lifting oil cylinder, the forward extending distance of a bridge and the height and the horizontal angle of a rail beam are adjusted by moving the rotating disc according to the working condition of a fast gun carrier, the consistency and synchronism during steering are guaranteed, the large stability of a precast beam is guaranteed, and transportation is completed.

Description

technical field [0001] The invention mainly relates to the technical field of road and bridge construction equipment, in particular to a bridge transport vehicle. Background technique [0002] The bridge transporter is a concrete beam transport machine specially designed for the erection of highway and railway bridges. It consists of three independent operating mechanisms (tractor, semi-trailer, and fast gun). The tractor is equipped with a diesel engine to provide driving force for the whole vehicle after deceleration, and the final drive is planetary gear transmission. Set hydraulic power steering and air brake functions. There are multiple forward and reverse gears. A single-cylinder diesel engine provides power for hydraulic steering. The bridge transport vehicle has the functions of transporting beams and feeding beams to the bridge erecting machine (the beams are transported under the gantry crane in the concrete girder yard and transported to the bridge erecting m...
