Lengthened type concrete spraying vehicle manipulator

Abstract

The invention relates to the field of concrete spraying vehicle designing in engineering machinery, in particular to a lengthened type concrete spraying vehicle manipulator. The lengthened type concrete spraying vehicle manipulator is composed of a non-eccentric folding manipulator device, a sliding block mechanism, a scraper mechanism and an automatic lubrication device. The lengthened type concrete spraying vehicle manipulator solves the problem that in the prior art, a sliding plate, guide wheels and a telescopic arm are prone to abrasion, the problem that concrete attached to the telescopic arm needs to be cleared away in time, the problem that an oil cylinder push-pull type folding device and a manipulator are arranged eccentrically, so that the stability of a complete machine is poor, the problem that as a base of a rotary reducer type folding device is not provided with a leveling mechanism, the rotary reducer type folding device is prone to damage in the using process and the problem of designing the weight reduction design scheme of a concrete spraying vehicle manipulator. According to the concrete spraying vehicle manipulator, the length of the manipulator is increased, and therefore the operating range of the manipulator is expanded. The invention further provides a swing mechanism, so that the flexibility of operation is improved, and the load borne by the whole manipulator is relieved.

Description

technical field [0001] The invention relates to the design field of construction machinery concrete spraying vehicle, in particular to an elongated concrete spraying vehicle manipulator. Background technique [0002] In recent years, with the rapid development of my country's economy, the machinery industry has developed rapidly, and the development of the construction machinery industry has been particularly prominent. Construction machinery products such as concrete spray vehicles have been widely used in the construction of railways, highways, water conservancy and other construction projects. Among them, it has become an ideal construction operation machine for temporary and permanent support of tunnels, road slope protection, and underground engineering. [0003] In the prior art, the telescopic arm of the manipulator of the concrete spraying vehicle is guided by a slide plate or a guide wheel. The telescopic arm stretches frequently, and the friction force on the slide ...

AI Technical Summary

Problems solved by technology

Oil cylinder push-pull folding device, the manipulator is eccentrically folded, which is not good for the stability of the whole machine; the rotary reducer type folding device is not eccentrically folded, but the base of the rotary reducer has no leveling mechanism, and the rotary reducer type folds during use. The device is easily damaged, resulting in that the telescopic arm connected to the rotary reducer cannot be stretched after the rotary reducer rotates at a certain angle

The weight of the manipulator of the concrete shotcrete truck has always been a problem. The manipulator is too heavy, which increases the burden on the manipulator, affects the flexibility of the manipulator, and reduces the spraying efficiency of the concrete shotcrete truck.

[0004] In the prior art, there is still a technical problem that the construction scope of the concrete spraying vehicle is limited due to the insufficient length of the mechanical arm of the concrete spraying vehicle

For high slopes and high tunnels in water conservancy and hydropower construction operations, existing concrete shotcrete trucks cannot reach the spray height required for the operation; for step method excavation operations, the top spraying of concrete gunite trucks will encounter difficulties, and some dead angles may even be impossible. to spray
