Lateral hole puncher for bridge pile foundations

Abstract

The invention discloses a lateral hole puncher for bridge pile foundations. The hole puncher comprises a bottom plate, a driving device is arranged at the top of the bottom plate, an output shaft of the driving device is fixedly connected with a drill bit, both sides of the top of the bottom plate are fixedly connected with support rods, the top parts of the four support rods are fixedly connectedwith top plates, the inner parts of the support rods sleeve first screw rods in a threaded mode, first cavity blocks movably sleeve the outer sides of the bottom ends of the first screw rods, and thebottom parts of the first cavity blocks are fixedly connected with upper pressure plates; through the designed first screw rods, the first cavity blocks and the upper pressure plates, the top part ofthe driving device can be fixed, and through the arrangement of second screw rods, second cavity blocks and first side pressure plates, the right side of the driving device can be fixed, so that theposition of hole punching is effectively avoided from changing during hole punching, the precision of hole punching is improved, and the problem of low precision of hole punching of an existing deviceis solved.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a side puncher used for bridge pile foundations. Background technique [0002] The bridge pile foundation is also called the bridge foundation. The bridge pile foundation is the lowest part of the bridge structure that is directly in contact with the foundation. It is an important part of the lower structure of the bridge. After the foundation is subjected to various loads, it will produce stress and deformation. In order to ensure the normal use and safety of the bridge, the foundation and foundation must have sufficient strength and stability, and the deformation should also be within the allowable range. Need to adopt hole puncher to carry out punching at the side position of bridge pile foundation sometimes, yet the side position puncher that occurs on the market still has various deficiencies, can not satisfy the demand of production. [0003] When the existing ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a side hole puncher for bridge pile foundations, to solve the problem that the existing side hole punchers proposed in the above-mentioned background technology are difficult to drill due to the relatively high hardness of the bridge pile foundation when punching holes. When performing the drilling operation, the drilling accuracy will be affected due to excessive resistance. At the same time, due to the long-term work of the punch during the drilling process, the temperature of the drill bit of the punch will increase, resulting in a decrease in drilling efficiency. , and because the positions of the holes required for the bridge pile foundation are different, the existing hole punchers need to be manually controlled when punching holes, which will greatly increase the labor intensity of the staff
