Problems solved by technology

The traditional chiseling treatment on the concrete surface is done manually by on-site workers, which has a large workload and low efficiency, and the chisel quality is uneven, making it difficult to meet the engineering quality requirements; at present, some construction sites sometimes use chisel machines to achieve concrete removal. Some chisels include hand-held chisels and airborne chisels. Hand-held chisels are difficult to cover the entire tunnel lining surface and consume a lot of manpower; airborne chisels usually use special trusses to support the chisel. Although the chisel machine can chisel the working surface at any angle, its structure is complex and is easily affected by the construction space; at the same time, the existing chisel machine can only realize its chisel function, and does not have the synchronization of concrete spraying construction. function, there is a problem that chiseling is not immediate and it is difficult to remove after the concrete hardens

Embodiment 1

[0024] refer to figure 1 , a chiseling device with a spray unit, comprising a connecting frame and a spraying unit 4 and a chiseling unit 1 arranged on the connecting frame; Mechanism 103, the output end of the pneumatic device is connected with the chisel, the other end of the pneumatic device is connected with the buffer mechanism, and the buffer mechanism is arranged on the connecting frame; at the same time, the pneumatic device is provided with an external interface 1021, and the external interface is externally connected to the high-pressure air flow pipe The pneumatic device provides the axial impact power of the chisel to realize the chisel function of the chisel; the buffer mechanism is used to reduce the axial impact of the chisel unit on the connecting frame, the chisel is more stable, and it is convenient to control the chisel accuracy. The pneumatic device is a common pneumatic structural part in the existing chisel machine; the pneumatic device includes parts suc...

Embodiment 2

[0029] The difference between this embodiment and Implementation 1 lies in the difference of the steering device. The steering device of this embodiment includes a first rotary cylinder and a second rotary cylinder; the first rotary cylinder and the second rotary cylinder are vertically arranged, and the first rotary cylinder The output end is connected perpendicular to the connecting frame to connect the chiseling unit on the frame and the horizontal direction of the injection unit, and the output end of the second rotary cylinder is connected perpendicular to the first rotary cylinder to connect the chiseling unit on the frame to the spraying unit. Steering in the vertical direction of the unit.

[0030]It should be noted that the devices in the first embodiment and the second embodiment both include a pneumatic control system, and the pneumatic control system is configured with reference to the conventional pneumatic control system to control the movement of the cylinder.

Abstract

The invention provides a roughening device with a spraying unit. The roughening device comprises a connecting frame, and a spraying unit and a roughening unit which are arranged on the connecting frame. According to the roughening device, after the spraying unit communicates with a concrete pouring device, concrete pouring construction can be achieved, and meanwhile, the roughening unit can immediately conduct roughening treatment after concrete initial spraying pouring of the spraying unit, so that shoveling of over-sprayed concrete is achieved, the problem that the concrete is difficult to shovel after hardening due to untimely roughening is avoided, and the construction is convenient; and in addition, the roughening unit is fixedly connected with the spraying unit, and the roughening unit can conduct construction along with the spraying unit, so that the problems that at prior art, manual shoveling and a handheld roughening machine are difficult to cover the whole construction surface and large in labor consumption and roughening construction of an machine-mounted roughening machine is inconvenient to conduct and insufficient in construction space are effectively solved, the labor intensity of workers is greatly reduced, the construction efficiency is improved, and the construction is safe and reliable.

Description

technical field [0001] The present invention relates to a chiseling device, in particular to a chiseling device with a spray unit. Background technique [0002] In the process of concrete spraying, it is inevitable that concrete overspraying will occur in some places, which will affect the subsequent construction processes such as waterproofing board laying and secondary lining construction. It is usually necessary to immediately remove the overspray and the residual concrete on the arch frame manually or with the aid of a chisel machine. The traditional chiseling treatment on the concrete surface is done manually by on-site workers, which has a large workload and low efficiency, and the chisel quality is uneven, making it difficult to meet the engineering quality requirements; at present, some construction sites sometimes use chisel machines to achieve concrete removal. Some chisels include hand-held chisels and airborne chisels. Hand-held chisels are difficult to cover th...
