Extension arm mechanism with floating suspension arm of vacuum excavation machine

Abstract

The invention discloses an extension arm mechanism with a floating suspension arm of a vacuum excavation machine. The extension arm mechanism comprises a swing part, a stretchable part and a floatingpart; the swing part comprises a rotary table, a support, a lifting hydraulic cylinder and a swing arm, wherein the stretchable part comprises a stretchable hydraulic cylinder, a stretchable arm and asecond roller wheel base, and the floating part comprises the floating suspension arm, an elastic element, a droop arm and a hinge base; One end of the swing part is provided with the stretchable part, the other end of the stretchable part is provided with the floating part, and the swing part comprises the rotary table, the support, the lifting hydraulic cylinder, the swing arm, a first roller wheel base and a first roller wheel group. According to the extension arm mechanism, the extension arm mechanism has the advantages of being convenient to operate, capable of saving force, large in operation range, safe and efficient, and capable of being operated by a single person.

Description

Technical field: [0001] The invention relates to the technical field of vacuum excavation, in particular to an outrigger mechanism with a floating boom of a vacuum excavator. Background technique: [0002] Vacuum excavation equipment or vacuum excavator and vacuum excavation vehicle use high-pressure water to crush and decompose plain soil and materials that can be pulped or broken into small pieces, and at the same time use negative pressure suction and pneumatic conveying principles to suction and crush Small pieces of material enter the storage tank to realize the functions of cleaning and excavation; and it is a construction machine that can transport, separate and dump the materials sucked into the tank. The vacuum suction excavation method is a non-contact and non-destructive excavation method, which can effectively reduce ground damage during excavation, reduce damage to underground pipes, cables, trees, etc., and can realize excavation and suction cleaning in a narro...

AI Technical Summary

Problems solved by technology

This kind of boom can better solve the above problems, but unlike the sewage suction truck, the vacuum excavation equipment requires one person to hold the excavation head for excavation construction, so this kind of rotating boom is applied to the vacuum excavation equipment There is such a problem: since this kind of boom needs to be raised and lowered by the remote control, the equipment needs at least 2 people to operate when performing the excavation task.

This is prone to misoperation, resulting in a decrease in efficiency, and various dangers may occur
