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...

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Depend on Figure 1 to Figure 10 Given, the present invention includes a vertical and non-rotatable screw 1, the screw 1 is placed in the concrete reserved hole and coaxial with it, the screw 1 is sleeved with a threaded tube 2 that can actively rotate, and the threaded tube 2 and the screw 1 Through screw connection, the lower end of the threaded pipe 2 is equipped with a first planetary gear train, wherein the first sun gear 3 in the first planetary gear train is set on the lower end of the threaded pipe 2, and the threaded pipe 2 can drive the first sun gear 3 only when it rotates forward Rotation, the first planetary carrier 4 in the first planetary gear train can actively rotate, the first sun gear 3 in the first planetary gear train is opposite to the rotation direction of the first ring gear; there is a sec...
