Description

Technical Field

[0001] The invention relates to the technical field of construction engineering quality detection, in particular to a construction engineering quality detection and identification flaw detector. Background Art

[0002] Construction project quality inspection is a key link in ensuring the quality and safety of buildings. It mainly inspects building materials, components, structural entities, etc., covering the pre-construction, mid-construction and post-construction stages. Through on-site inspections such as rebound tester measurement and laboratory testing and analysis of samples, the performance of materials such as cement and steel is checked, the structural strength, internal defects and other conditions are evaluated, and indoor environmental indicators are also tested. Its purpose is to promptly discover quality risks, ensure that the building meets the relevant standards and requirements, can be safely delivered for use, and safeguard the rights and interests of users.

[0003] During the construction process, due to insufficient vibration: the concrete is not fully vibrated and the air is not completely expelled; the template joints are not well sealed or have holes, and the concrete slurry leaks out; the unreasonable layout hinders the flow of concrete, which can easily lead to the formation of cavities inside the template. Currently, workers normally detect the cavity by knocking with a small hammer, but this type of detection is very easy to miss, resulting in poor quality of the construction project, so it needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a flaw detector for detecting and identifying the quality of construction projects, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: a flaw detector for construction engineering quality inspection and identification, comprising a flaw detection mechanism, a top case of the flaw detection mechanism having a moving mechanism, and a right case of the moving mechanism having a protective mechanism; The flaw detection mechanism comprises a support frame, a mounting plate is hingedly connected to the top of the support frame, a bottom shell is rotatably connected to the top of the mounting plate, an instrument body is hingedly connected to the bottom shell, and a top cover is fixedly connected to the top of the instrument body; After pouring, the instrument body is used to detect the concrete pouring quality in the entire formwork. When a cavity is detected, it can be processed in a timely manner, thereby effectively solving the quality problems of the construction project caused by the cavity.

[0006] The protection mechanism includes a protection cover, which is arranged on the right side of the instrument body. A first support block is fixedly connected to the top of the protection cover.

[0007] When the device is not in use, because the environment at construction sites is generally poor and dusty, the instrument's main body detection head is easily covered with dust and damaged. The protective cover can effectively prevent the dust from affecting the instrument's main body detection head. At the same time, when in use, the protective cover can be flipped by extending and retracting the electric telescopic rod, which can effectively achieve the protection purpose without affecting actual use.

[0013] Preferably, the moving mechanism includes a slider, the slider is fixedly connected to the bottom of the moving seat, the bottom of the slider is slidably connected to a slide rail, the bottom of the slide rail is fixedly connected to the top of the top cover, the left and right sides of the slide rail are fixedly connected to fixed plates, the middle of the fixed plate is rotatably connected to a lead screw, the lead screw is threadedly connected to a ball nut pair corresponding to the moving seat, the top of the ball nut pair is fixedly connected to the middle of the bottom of the moving frame, the left end of the lead screw is fixedly connected to a first gear, the bottom of the fixed plate on the left side of the slide rail is fixedly connected to a gear rack, the gear rack is rotatably connected to a second gear, and the left side of the gear rack is fixedly connected to a motor corresponding to the second gear.

[0014] When it is necessary to remove the protective cover and protect the probe of the instrument body, the motor is started at this time, and the first gear and the second gear cooperate to realize the rotation of the lead screw. The rotating lead screw, in cooperation with the ball nut pair, can drive the slider to slide on the slide rail, thereby driving the moving seat to move, thereby making it more convenient to protect the protective cover and use the instrument body.

When the device is not in use, the protective cover can effectively prevent the dust from affecting the instrument's detection head because the construction site environment is generally poor and dusty, which can easily cause the instrument's detection head to be covered with dust and cause damage. At the same time, when in use, the protective cover can be flipped by extending and retracting the electric telescopic rod, which can effectively achieve the protection purpose while not affecting actual use.
