A kind of roughening device for concrete surface

Abstract

The invention belongs to the technical field of concrete chiseling, and specifically relates to a concrete surface chiseling device, which includes a mobile base and a chisel box; a circular through hole is opened on the top of the mobile base, and the bottom inside the circular through hole is fixedly connected There is an arc-shaped support frame; in the present invention, an arc-shaped connecting frame is connected by rotating in the middle of the mobile base, and the arc-shaped connecting frame is used to drive the chisel box to rotate, so that the relative position between the chisel box and the mobile base can be adjusted , it is convenient to store the shaving box, and the pin shaft is inserted into the round hole and the through hole, the connecting shaft slides inside the guide hole, and the direction of the shaving box can be adjusted, and the card that is rotated and connected on the telescopic arm The hoop is movably socketed with the side arm of the U-shaped handrail, and the vertical position of the vertically arranged chisel box can be adjusted through the cooperation of the motor, driving gear, driven gear and screw rod, so that the chisel box can be Chiseling on walls and ground to improve the efficiency of chiseling.

Description

technical field [0001] The invention relates to the technical field of chiseling concrete, in particular to a chiseling device for concrete surfaces. Background technique [0002] Concrete chiseling, in order to stick firmly, chisel the surface of the concrete as needed, and use it to clean floating ash, mortar, oil stains, etc. Chiseling is to roughen the smooth base surface to improve the adhesion of the mortar. Chiseling is the work of chiseling off the hard milk skin on the surface of old concrete with a chisel or a pick to form a rough surface in order to make the new and old concrete bond well. The chiseling depth shall be based on the fact that 1 / 3 to 1 / 2 of the stones on the old concrete are exposed. [0003] Most of the existing chiseling devices can only chisel on a single plane due to their large volume. In this way, when it is necessary to chisel the ground and the wall at the same time, it is necessary to select two chisel machines with different working modes...

Problems solved by technology

[0003] Most of the existing chiseling devices can only chisel on a single plane due to their large volume. In this way, when it is necessary to chisel the ground and the wall at the same time, it is necessary to select two chisel machines with different working modes. The chiseling device performs chiseling separately, thereby reducing the working efficiency of chiseling, and at the same time, it is not convenient to transfer chiseling devices with various working modes
