Problems solved by technology

The transmission rod of this tool can only slide up and down in the base rod, and cannot be fixed. In this way, when encountering different floor heights, in order to make the impact drill as close as possible to the ceiling, the operator can only hold the afterburner handle and lift it up. Adjust the vertical height position of the transmission rod by means of force, and at the same time use this method to control the depth of the impact drill into the ceiling, which has the disadvantages of laborious operation and difficult control accuracy

Abstract

The invention discloses a percussion drill support for overhead drilling construction. The percussion drill support is suitable for overhead drilling on the bottom of a beam and slab. The percussion drill support comprises a force application mechanism, a layer height adjustment mechanism, and a percussion drill fixing mechanism. The force application mechanism is a four-connecting-rod mechanism composed of a floor standing post, a horizontal force application rod, a moving standing post and a horizontal connecting rod. A lever mechanism is formed by the floor standing post and the horizontal force application rod. The layer height adjustment mechanism comprises a support connecting pipe and a layer height adjusting rod. Two ends of the layer height adjusting rod is slidingly connected with the support connecting pipe and the moving standing post through clamping nuts. The percussion drill fixing mechanism comprises a support and a binding rigging. The support is fixed onto the support connecting pipe. The percussion drill support is safe and convenient to construct, labor-saving to operate, and effective in improving working environment.

Description

technical field [0001] The invention relates to a bracket used in conjunction with a percussion drill, in particular to a percussion drill support for up-drilling construction, which is suitable for performing up-drilling operations during drilling construction on the bottom surface of concrete beams and slabs. Background technique [0002] In construction projects for new construction or renovation of old houses, it is often necessary to drill holes on the bottom of concrete beams and slabs, and then use rear expansion bolts or chemical bolts to install pipeline bridges for water heating and electricity or for keel installation for interior decoration. Due to the construction under the concrete beam slab, upward drilling is required, so that the operator stands on the scaffold to work at a high altitude, and the impact drill is lifted above the head for construction, which is very laborious and the labor intensity of the workers is high; at the same time, the upward drilling...
