Concrete hole wall scrabbling device

Abstract

The invention provides a concrete hole wall scrabbling device and solves the problems that according to the prior art, great labor force is required in hole wall scrabbling, scrabbling strength cannotbe easily controlled, hole wall scrabbling is uneven, operations are complicated, scrabbling density cannot be adjusted, and onsite construction requirements cannot be duly met. According to the technical scheme, the device comprises a screw rod; the screw rod is provided with a threaded pipe; a first planetary gear system is arranged at the lower end of the threaded pipe; the threaded pipe can only drive a first sun gear to rotate through forward rotation; a first planetary carrier can actively rotate; the rotating direction of the first sun gear is opposite to that of a first gear ring; a second planetary gear system is arranged below the first planetary gear system; a second sun gear is sleeved with the lower end of the threaded pipe; the threaded pipe can only drive the second sun gear to rotate through reverse rotation; the rotating direction of a second gear ring is consistent with that of the second sun gear; the first planetary carrier can drive a second planetary carrier to rotate; a circular cylinder is arranged on the outer side of the first gear ring; and a plurality of circumferentially and evenly distributed scrabbling tools are arranged on the outer side of the circular cylinder.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a concrete hole wall chipping device. Background technique [0002] At present, during construction work, there are often reserved holes on the building surface for the installation and use of subsequent equipment or parts. In order to ensure that the parts can be fixed firmly, the side walls of the holes are usually roughened before concrete sealing. For example, the construction of anti-floating anchor rods. [0003] In the prior art, most chisel machines can only deal with the exposed surface. For the inner wall of the hole after concrete drilling, it is impossible to chisel it. The traditional hole chiseling method is to use a steel sheet to beat in the hole to damage the hole wall. Make it rough and increase the friction force. With this method of hole processing, the steel sheet can swing in a limited angle in the hole, and the processing point is limited to...

Problems solved by technology

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a concrete hole wall chiseling device, which solves the problem of large amount of manpower and difficulty in controlling the chiseling strength in the prior art in the hole wall chiseling construction, and the problem of The wall chisel is uneven, the operation is cumbersome, the density of the chisel cannot be adjusted, and it cannot be well adapted to the requirements of on-site construction.
