Building concrete core drilling machine

Abstract

The invention discloses a concrete drilling and coring machine for construction, which includes a frame, a backing plate, a ground wheel, a motor, a transmission shaft, a guide rod, an upper beam, a sliding frame, a coring drill bit, and a clamping device. A ground wheel is provided on the lower side of the frame, a clamping device is provided on one side of the frame, a number of lead screws I are provided on the frame, a backing plate is provided on the lower side of the lead screw I, and a backing plate is provided on the upper side of the frame. There is a guide rod, the top of the guide rod is provided with an upper beam, one side of the upper beam is provided with a screw II, the top of the screw II is provided with a hand wheel, and the lower side of the upper beam is provided with a sliding frame. A motor is provided on one side of the sliding frame, and the motor drives the transmission shaft to rotate through a belt. The transmission shaft is provided with a coring drill bit, and a protective ring is provided outside the coring drill bit. The invention can keep the drilling rig stable and the drill bit stable during work, improve the quality of coring, prevent sewage from splashing randomly, and dirty the clothes of the staff.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, in particular to a concrete drilling and coring machine for construction. Background technique [0002] Concrete drilling and coring machine mainly has two purposes, one is for horizontal drilling, it is suitable for road stud installation, road pile drilling and coring machine installation, bridge drilling operation rules, integrated house pile foundation drilling, etc., has been widely used It is used in transportation engineering companies, China Railway Group, integrated housing companies and other units; the second is for coring, which is suitable for road surface coring for testing, and has been widely used in testing centers around the world. [0003] The following problems exist in the application of drilling and coring machines: 1) Due to the high-speed movement of the drill bit during work, the inclination and instability of the equipment will affect the drill bit, shorte...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the application of drilling and coring machines: 1) Due to the high-speed movement of the drill bit during work, the inclination and instability of the equipment will affect the drill bit, shorten the service life of the drill bit, and also affect the quality of coring; 2) The drill bit When it touches the ground, it will shake, which will also affect the quality of coring; 3) Since the coring machine needs to continue to add water to cool it when it is working, there will be sewage splashing and dirty the clothes of the staff
