Wheeled engineering machine as well as disassembling method and assembling method thereof

Abstract

The invention discloses a wheeled engineering machine, which comprises an automobile chassis part (1) and an assembled part (2) supported on the automobile chassis part (1), wherein the assembled part (2) is in detachable connection with the automobile chassis part (1). By adopting the structural form, multiple different assembled parts can be replaced and assembled on one automobile chassis part, thus the matching property and universality of the automobile chassis part and the assembled part are enhanced; and the production cost is saved and the wasting of fund is avoided. The invention also provides a disassembling method and an assembling method of the wheeled engineering machine. The purpose of separating and combining the assembled part and the automobile chassis part is realized by controlling the supporting leg of the assembled part to make the supporting leg extend and shorten, the disassembling and assembling of the wheeled engineering machine are simply and conveniently realized, and the wheeled engineering machine has the characteristics of convenience for disassembling and assembling and agility in operation.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wheeled engineering machinery. In addition, the present invention also relates to a split method and a combined method of the above-mentioned wheeled construction machinery. Background technique [0002] The concrete pump truck is a commonly used wheeled construction machinery, mainly including the chassis part and the upper part of the car. The chassis part of the car includes the cab, wheels and chassis, etc. It is not only used for the transportation of the concrete pump truck, but also plays the role of supporting the upper part. The upper part is installed on the chassis of the car, mainly including the pumping mechanism and the boom system, etc., and plays the role of pumping concrete materials. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a concrete pump truck in the prior art. The following briefly introduces th...

AI Technical Summary

Problems solved by technology

[0005] However, since the upper body part and the chassis part of the car adopt the above-mentioned welded integrated structure, one upper part can only be assembled with one car chassis part, resulting in poor compatibility and versatility between the car chassis part and the upper part of the concrete pump truck. Every time a manufacturer produces an upper body part, it must produce a car chassis to assemble it at the same time. As a result, the manufacturer produces a variety of concrete pump truck series according to different specifications of the car chassis and different lengths of the boom, with various types and models. cost of production

In addition, if customers need to use different bodywork parts, they need to purchase multiple complete sets of equipment, resulting in a lot of waste of money
