Problems solved by technology

The use of semi-trailer transport vehicles mainly has the following disadvantages: first, the vehicle body is long, and there are certain difficulties in reversing, which requires a large site for U-turn; The power of the brake drum is limited. When encountering a large slope, the climbing power is insufficient, which is more dangerous. At the same time, the heat of the brake drum when going downhill will easily cause the friction lining to burn, resulting in accidents; the turning radius of the road during transportation is more demanding. Large, the length of the channel beam is generally 20-30 meters, and the turning radius inside and outside is relatively large when turning. At the same time, it is easy to cause danger to surrounding pedestrians and vehicles during transportation.

Abstract

The invention discloses a self-propelled channel beam transport vehicle which is applicable to transporting channel beams of railways and comprises a main structure, hydraulic suspension systems, a multi-axis vehicle axle, a steering system, a braking system, a power system and an electro-hydraulic control system. The main structure comprises a pair of main beams and an inverted 'concave' main frame structure, the main beams are arranged in a bilateral symmetry manner, the inverted 'concave' main frame structure comprises crossbeams and end crossbeams which are connected between the main beams, two cabs are respectively connected to the front and the rear of the main structure, driving axles are arranged in the front of a vehicle body, driven axles are arranged at the rear of the vehicle body, suspension cylinders of the various hydraulic suspension systems positioned on the various driving axles on the left side and the right side of the longitudinal axle of the main structure are serially communicated with one another to form two groups respectively, all suspension cylinders of the various hydraulic suspension systems positioned on the various driven axles on the left side and the right side of the longitudinal axle of the main structure are serially communicated with one another to form two groups respectively, steering connecting rods of the driving axles are arranged in an inverted splay manner, and steering connecting rods of the driven axles are arranged in a splay manner. The self-propelled channel beam transport vehicle has the advantages that the self-propelled channel beam transport vehicle can run in two directions, is flexible in steering and high in field adaptability, the channel beams can be transported in an online manner, the transport efficiency can be greatly improved, and the under-bridge transport road construction cost is saved.

Description

technical field [0001] The invention relates to a vehicle used for bridge transportation, especially a channel beam transportation vehicle. Background technique [0002] With the continuous progress of my country's bridge construction technology, the current domestic railway bridge construction technology is developing in the direction of "centralized prefabrication, transportation and erection". At present, the box bridge construction equipment is relatively mature, mainly self-propelled tire transport vehicles for transportation operations, The bridge erecting machine is responsible for the construction of the girder, and the two types of equipment cooperate with each other to complete the erection task of the box girder. [0003] Channel beam is a new type of bridge suitable for windy areas. Its cross section is roughly U-shaped. It is used as the upper structure of railway bridges. It has the advantages of reducing noise, windproof and earthquake resistance. In the past,...
