Concrete core drilling machine for construction engineering quality supervision

Abstract

The invention relates to the technical field of construction engineering devices, and discloses a concrete core drilling machine for construction engineering quality supervision, which comprises a bottom frame; cylinders are fixedly arranged on the four corners of the top of the bottom frame correspondingly, the cylinders movably sleeve inner cylinders on the inside, and the inner cylinders movably sleeve round rods on the inside;the bottom ends of the round rods penetrate through and extend below the bottom frame and areclamped with backing plates,an adjustment mechanism is fixedly mounted onthe top ends of the round rods, both sides of the adjustment mechanism penetrates through and extends to the outside of the two sides of the cylinders, and circular bubble level is fixedly mounted inthe middle of the top surface of the bottom framethrough a mounting rod. According to the concrete core drilling machine for construction engineering quality supervision, improvement is conducted byadjusting the feeding speed of the drill bit through the form of a traditional hand screw, and a gear mounted on a round shaft is driven to rotate by pulling a monkey wrench, and a rack is driven to move up and down by a gear to drive the drill bit of the concrete core drilling machine to move so as to complete the work of coring, controlling of the feeding speed of the drill bit is benefited, andthe labor intensity of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a concrete drilling and coring machine for quality supervision of construction engineering. Background technique [0002] The concrete coring machine is mainly used for sampling the concrete layer in the project. It adopts a multi-purpose machine, which can drill and core, cut the core sample and grind the core sample, which greatly improves the work efficiency. It is an ideal engineering testing equipment. [0003] When using a concrete coring machine for coring work, the bottom wheels are put away so that the bottom frame touches the ground. However, it is difficult to turn the wheels over in this process, and after turning over, because the construction ground is not completely horizontal, the bottom frame touches the ground. It is difficult to ensure the level of the concrete coring machine after the ground, and the drill bit is easy to damage the d...

Problems solved by technology

[0004] The invention provides a concrete drilling and coring machine for quality supervision of construction projects, which has the advantages of ensuring the levelness of the concrete coring machine and being easy to adjust the feed speed and easy to operate, and solves the problem that the construction ground is not completely level It is difficult to ensure the level of the concrete coring machine after the frame touches the ground, and the drill bit is easy to damage the drill bit when taking the core. At the same time, the traditional method of adjusting the feed speed of the drill bit in the form of a hand-operated screw requires a relatively fast shaking speed, which increases the labor load of the user. question
