Mechanical-arm guniting operation platform

Abstract

The invention provides a mechanical-arm guniting operation platform which comprises a walking machine body, a telescopic arm and a lifting device, wherein the telescopic arm is hinged on the walking machine body; the lifting device is arranged on the walking platform and used for lifting the telescopic arm; an operation platform is fixedly arranged at the top end of the telescopic arm; a rotating frame which can rotate around a vertical axis is arranged at the lower portion of the operation platform; a revolving shaft is rotatably connected with the top end of an extending portion of the rotating frame; a spray gun operation arm is hinged on the revolving shaft; a spray gun is fixedly installed on the spray gun operation arm; a feed box is arranged on the walking machine body; and the spray gun is communicated with the feed box through a conveying pipe. The mechanical-arm operation platform has the advantages as follows: the operation frequency is low; no viewing-angle dead zone is caused; a material can be sprayed uniformly, and no areas are omitted; and the machine works for a single time, and the spouting range is wide.

Description

technical field [0001] The invention relates to a tunnel engineering machine, in particular to a mechanical arm spraying operation platform used for sizing and painting the tunnel wall during tunnel construction. Background technique [0002] In recent years, in order to adapt to economic development, the country has continuously increased its investment in infrastructure such as roads and bridges. During road construction, especially in places with complex terrain, it is necessary to do a lot of temporary protection or initial support during tunnel construction. Spraying is an essential process. In the current construction, the spraying of the initial support of the tunnel is mainly completed by a fully automatic spraying machine or manual spraying. The spraying angle and range of the concrete spray gun used on the automatic spraying machine are determined by the control system set on the machine. Controlled, when spraying, the operator controls the control button or handl...

AI Technical Summary

Problems solved by technology

In the current construction, the spraying of the initial support of the tunnel is mainly completed by a fully automatic spraying machine or manual spraying. The spraying angle and range of the concrete spray gun used on the automatic spraying machine are determined by the control system set on the machine. Controlled, when spraying, the operator controls the control button or handle set on the machine in a timely manner through visual inspection to control the spraying range and spraying angle of the spray gun, so as to complete the spraying of concrete on the wall of the cave. This fully automatic spraying Although the slurry machine can complete the spraying of concrete on the wall of the cave, there are still certain problems in actual use. It is easy to produce blind areas of viewing angles, resulting in missed spraying or insufficient spraying materials in local areas, which directly affects the construction quality. There are defects in observation blind spots and easy to miss spraying materials; , because the spraying range of the spray gun itself is relatively narrow, in order to realize the continuous brushing of the tunnel wall without intervals, the machine needs to be moved continuously during actual operation, which increases the trouble of operation, and there is a single dwelling spraying range of the machine Small size and high frequency of operation; on the other hand, because the control system of the machine is more complicated, the difficulty and maintenance cost of the machine will increase accordingly, and there is a defect of high use cost
