Pitching type bearing frame for high-speed beam transport vehicle

Abstract

Disclosed is a pitching type bearing frame for a high-speed beam transport vehicle. The pitching type bearing frame comprises a vehicle frame, a pitching frame and a bearing turntable frame arranged on the upper portion of the pitching frame, the bottom of the pitching frame is fixed to the vehicle frame through a hinge component and freely swings front and back, the bearing turntable frame comprises a rectangular bearing frame and a rotating disc, and the rectangular bearing frame is fixed above the pitching frame through the rotating disc. The pitching type bearing frame for the high-speed beam transport vehicle overcomes defects in the prior art and comprises the pitching frame at the lower part and the bearing turntable frame at the upper part; during uphill climbing, a truss girder ispitched, the pitching type bearing frame can rotate along with the truss girder, and the good contact between the truss girder and the pitching type bearing frame is ensured; the transport safety iseffectively improved, the anti-overturning stability is high, the structure is simple, the manufacturing cost is low, and the pitching type bearing frame is convenient to use.

Description

technical field [0001] The invention relates to the technical field of high-speed beam transport vehicles, in particular to an auxiliary vertical bearing frame for high-speed beam transport vehicles. 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 m...

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
