A chiseling device for curved concrete surface of tunnel lining tiles

Abstract

The invention discloses a chiseling device for the curved concrete surface of tunnel lining tiles, which comprises a traveling mechanism, a working frame arranged beside the traveling mechanism, a roughing car installed on the working frame, a lifting and lowering drive mechanism, a telescopic rod mechanism, and a working frame The bottom of the chisel is hinged on the walking mechanism; the chisel car includes a car frame and a chisel box, a vibrating motor is installed on the chisel box, a chisel head is installed on the side of the chisel box close to the curved concrete surface of the tunnel, and the chisel box is far away from the tunnel A push piece is installed on one side of the curved concrete surface. The present invention does not need to set up a working platform during construction, and the chisel car can move up and down along the work frame, and at the same time, the chisel car moves back and forth in the direction of the curved concrete surface of the tunnel through the vibration motor to chisel, which improves the chiseling efficiency and construction safety factor. The construction period is shortened, and the distance between the working frame and the curved concrete surface of the tunnel is adjusted through the telescopic rod mechanism, so that the chiseling device is suitable for chiseling the curved concrete surface of the tunnel, and the applicable range of the chiseling device is expanded.

[0002] In the construction of highway tunnels, the pasted ceramic tiles for the secondary lining are the key appearance construction structure, and a large amount of manpower and material resources are invested in the entire tunnel construction process. In the later stage of tunnel construction, the construction period is generally tight, and the appearance and pasting quality of the lining tiles are high. Before pasting the tiles, it is necessary to chisel the concrete surface of the tiles. The depth and density of the chisel directly affect the quality of the secondary lining tiles. Therefore, in the specific construction, the depth and density of the chisel need to be strictly controlled, especially for When the surface of the curved concrete is chiseled, the construction is difficult and the construction period is long

[0003] In the prior art, the following chisel tools are used when chiseling the concrete surface. The first one is a chisel hammer, which is used to strike the concrete surface with a chisel hammer. This chisel method is suitable for chiseling a small area of ​​concrete surface. For example, projects such as tunnels that require large-scale chiseling have poor applicability; the second type is a hand-held electric chisel or a hand-held pneumatic chisel. The hand-held electric chisel is more convenient to operate, but road tunnels The power supply system in the later construction of the cave has been basically dismantled, and it is extremely inconvenient to use a generator to enter the tunnel to provide power for the electric chisel machine. The hand-held pneumatic chisel machine needs an electric or diesel air compressor when it is in use, but the diesel air compressor is prone to damage. Loud noise or a large amount of toxic and harmful exhaust gas will cause air pollution in the cave, and the working environment of the construction personnel is harsh. At the same time, the operators need to operate on a high working platform when chiseling at a high position. When the chiseling position is moved, the working platform needs to be moved accordingly, which is complicated to operate, and for large-area tunnel projects, the chiseling efficiency is low and the applicability is poor; the third type is a mobile electric or pneumatic chisel machine, which is currently on the market. The chisel, whether it is electric or pneumatic, is used for chiseling the floor. There is no chisel for the opposite surface, especially when the concrete surface in the tunnel is a curved surface, only a small hand-held chisel can be used for construction. Low efficiency, long construction period, poor applicability
