Crawler transporter with automatic loading and unloading function

Abstract

The invention discloses a crawler transporter with an automatic loading and unloading function. The crawler transporter with the automatic loading and unloading function comprises crawler beams, a transporter frame, a rotating platform, a lazy arm, a power box, a pitching oil cylinder, crawler beam brackets and transport boxes, wherein the transport boxes are split type transport boxes, and the two transport boxes are independently arranged on the left side and the right side correspondingly; the crawler beam brackets are mounted on the crawler beams, and the two transport boxes are mounted on the left crawler beam bracket and the right crawler beam bracket correspondingly; and one end of the transporter frame is connected with the power box, and the other end of the transporter frame is in lap joint with the crawler beams. The distance between the two crawler beams is changed by changing the lap joint lengths of the transporter frame and the crawler beams, and thus crawler chassis are made to stretch and retract to achieve rail changing; and the rotating platform is arranged on the power box, the lazy arm and the pitching oil cylinder are mounted on the rotating platform, and the telescopic end of the pitching oil cylinder is hinged to the middle of the lazy arm, so that pitching of the lazy arm is achieved, and the lazy arm is driven by the rotating platform to rotate. The requirement for complete machine transportation and the requirement for the stability of a complete machine under different transportation width conditions are met; and the center-of-gravity position of the complete machine can be adjusted through rail changing in the hoisting process, and thus the stability of the complete machine is improved.

Description

technical field [0001] The invention relates to a self-loading and unloading crawler transport vehicle, in particular to a self-loading and unloading crawler transport vehicle for hoisting and transportation on special terrain. Background technique [0002] The crawler transport vehicle belongs to the large-scale transportation equipment relying on the crawler walking device under special terrain. At present, there are mainly crawler pipe transport machines, crawler transport vehicles and other equipment. The crawler pipe conveyor is an important auxiliary construction equipment in the construction of oil and gas pipelines. It is mainly used for long-distance transportation of steel pipes in the construction of large-diameter oil and gas pipelines. Crawler transport vehicles have high off-road performance, adapt to harsh road conditions such as ditches, steep slopes, and steps, and are widely used in agriculture, exploration, deep forest, fire protection, military and other...

AI Technical Summary

Problems solved by technology

Loaders and pipelayers can only transport small-diameter steel pipes due to the space limitation of the host machine, and can only transport up to 2 pipes for large-diameter equipment, and the walking speed is slow and the transportation efficiency is low

In the field of pipeline transportation, there are many pipe transportation machines, which can only transport two large-diameter steel pipes at most, and have a single function.

[0004] Disadvantages of the existing technology: At present, crawler pipe transport machines are mainly used in the field of oil pipeline laying, which can only meet two steel pipes with a diameter greater than 1m, and cannot meet the transportation of four large-diameter steel pipes.

Crawler conveyors are mainly high-speed crawler chassis with low carrying capacity and are not suitable for mountain transportation of heavy equipment
