Transferring device and transferring method for engineering machinery vehicle

Abstract

Provided is a transfer equipment for construction machinery vehicles, used to carry the construction machinery vehicle for transfer. The construction machinery vehicle comprises a drive wheel (11), and a working wheel (12); the working wheel is disposed at the front part of the working end (13) of the construction machinery vehicle; the transfer device comprises a vehicle frame (20), a first wheel (31), and a second wheel (32); the vehicle frame is used to load the working end of the construction machinery vehicle during transfer; the first wheel and the second wheel are respectively and pivotally connected to the two sides of the vehicle frame; and under the drive of the drive wheel, the transfer device travels synchronously with the construction machinery vehicle. Also provided is a transfer method for the construction machinery vehicle: using the transfer device to bear the working end of the construction machinery vehicle, and utilizing the drive wheel of the construction machinery vehicle to enable the transfer device to travel synchronously with the construction machinery vehicle, so as to complete the transfer operation. The transfer device is of simple structure, easy operation and low cost, will not cause damage to the ground, and will not cause the mud scraper of the working wheel to fail, while significantly reducing the risk of the whole vehicle tipping during transfer.

Description

Technical field [0001] The invention relates to the field of engineering vehicles, in particular to a field transition device and a field transition method used for field transition of engineering machinery vehicles. Background technique [0002] Construction machinery vehicles are widely used in the construction of roads, dams or reservoirs and other engineering fields. Among them, single-drum vibratory rollers are used in various compaction operations to cause permanent deformation and compaction of the rolled layer. During the construction process, the roller needs to be transferred. [0003] However, because these construction machinery vehicles are prone to damage roads and bridges when they are running, they are generally not allowed to drive directly on roads and bridges, and specific transition devices are required to perform transition operations on them. [0004] The patent application number 201010594567.8 discloses a road roller, which can receive four wheels for transit...

AI Technical Summary

Problems solved by technology

[0005] However, since the hydraulic cylinder and the wheels of the road roller of the prior art are in the working area of ​​the working wheel, when the road roller is in working condition, if there is empty soil on the road surface, too much soil will be accumulated between the hydraulic cylinder and the working wheel. The mud scraper of the working wheel will fail; the driving process will cause a large impact on the hydraulic cylinder, which will shorten the service life of the cylinder or even cause damage; and because the diameter of the rear wheel is small, the working end of the roller is heavy. If it is uneven, it is easy to overturn; in addition, due to the design of the four transition wheels, the oil supply to the oil cylinder needs to be bypassed from the main system design, and each vehicle needs to be equipped with one set, resulting in an increase in cost
