High-speed beam carrier

Abstract

A high-speed beam carrier comprises an active vehicle and a tractor. The active vehicle and the tractor each comprise a driver's seat, a frame, an axle, wheels and a pitching bearing frame. Each pitching bearing frame comprises a pitching frame at the lower part and a bearing turnplate frame at the upper part. The bottom of each pitching frame is fixed on the corresponding frame through a hinge part. A rotating shaft is arranged on each hinge part. Each rotating shaft is parallel to the corresponding axle. Each bearing turnplate frame comprises a rectangular bearing frame and a rotating disc.The rectangular bearing frames are fixed above the pitching frames through the rotating discs separately. According to the invention, the defects in the prior art are overcome, the pitching bearing frames are arranged on the frames, each pitching bearing frame comprises the pitching frame at the lower part and the bearing turnplate frame at the upper part, at the uphill, concrete beams are pitched, the pitching bearing frames can follow and rotate, so that concrete beams and the pitching bearing frames are in good contact, the transportation safety is effectively improved, and the anti-overturning stability is high.

Description

technical field [0001] The invention relates to the technical field of a beam-carrying cannon, in particular to a high-speed beam-carrying cannon. Background technique [0002] The beam transporter is a prefabricated beam transport machine specially designed for highway bridge erection. It consists of two independent operating mechanisms (active vehicle, passive vehicle). The main vehicle is equipped with a four-cylinder or six-cylinder diesel engine to provide driving force for the whole vehicle through four-stage deceleration. The final drive is wheel gear or planetary gear transmission. Set hydraulic steering and air brake functions. Generally, there are multiple forward gears and reverse gears. The auxiliary vehicle is equipped with a single-cylinder diesel engine to provide power for hydraulic steering. The beam transporting cannon has the functions of transporting beams and feeding beams to the bridge erecting machine (the beams are transported under the gantry cr...

AI Technical Summary

Problems solved by technology

[0003] The configuration of the common fast guns on the market is relatively simple. When driving at high speed, the performance in terms of passability, ease of use, and durability is relatively backward. Most of them adopt a structure similar to that of a workshop transfer flat car, and the axles are fixed on the frame with bolts.

This will lead to poor adhesion of the tires on uneven roads, and on roads with large longitudinal slopes, the beam-loading turntable will damage the concrete beams, and cause local stress concentration on the frame and plastic deformation of the body
