Description
Technical Field
[0001] The utility model belongs to the technical field of building engineering quality inspection, and particularly relates to a steel bar detection device in a concrete structure. Background Art
[0002] At present, most building engineering projects are constructed with reinforced concrete. After the building is completed, it is necessary to conduct quality inspection on the overall building structure, especially the inspection of steel bars. In the prior art, a steel bar detector is used to detect the distribution, direction, diameter of steel bars in the building structure, and the thickness of concrete. When using a steel bar detector to detect a concrete structure, the roller on the steel bar detector is attached to the wall surface, and then the steel bar detector is held by hand and moved on the wall surface. Since the wall surface is basically a rough surface and is not flat, when the roller rolls on the rough surface, it is easy to cause the shaking and deviation of the steel bar detector, resulting in errors in indicators such as the diameter of the steel bar and the thickness of the concrete.
[0003] Chinese Patent (CN11187934A) discloses a portable steel bar detector for building engineering quality supervision. In this technical solution, a spring structure is provided on the roller to reduce the shaking generated when the steel bar detector rolls on the wall surface. However, the spring structure cannot completely avoid the shaking of the steel bar detector. It is urgent for those skilled in the art to propose a detection device in which the steel bar detector will not shake due to the uneven wall surface. Summary of the Utility Model
[0004] In view of this, the utility model provides a steel bar detection device in a concrete structure to solve the above problems.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A plurality of abutting columns are provided on the moving support groove, and the abutting columns are used to abut against the concrete structure to be detected. The abutting columns are higher than the steel bar detection probe. The top end of the hand-held rod is movably connected to the rear side wall of the moving support groove, and a control display panel is provided on the hand-held rod. The steel bar detection probe is electrically connected to the control display panel.
[0007] Further, it further includes a driving device, the driving device includes a first motor and a threaded rod, both ends of the threaded rod are rotatably connected to the two side walls of the moving support groove, the threaded rod is parallel to the length direction of the moving support groove, the threaded rod passes through the moving block inside the moving support groove and is threadedly connected to the moving block, the first motor is fixedly installed on the outer side wall of the moving support groove, one end of the threaded rod is fixedly connected to the output end of the first motor, and the first motor is electrically connected to the control display panel.
[0008] Further, telescopic grooves are provided in each of the plurality of abutting columns, and a fixing device is provided in the telescopic grooves. The fixing device includes a spring and a fixing cone. One end of the fixing cone is provided with a first cone head, and the other end extends into the telescopic groove and is slidably connected to the side wall of the telescopic groove.

[0011] The beneficial effects of the present utility model are as follows:
[0012] In the present utility model, the abutting columns are abutted against the wall surface of the concrete structure to be detected. Since the abutting columns are higher than the steel bar detection probe, it does not affect the smooth movement of the steel bar detection probe in the moving support groove, thus avoiding the rolling of the rollers of the traditional steel bar detector on the uneven wall surface, causing the shaking and tilting of the steel bar detector, and affecting the detection results of indexes such as the steel bar and the concrete thickness. The spring pushes the fixing cone outwards in the telescopic groove, the first cone head abuts against the wall surface of the concrete structure to be detected, and the plurality of fixing cones on the moving support groove simultaneously abut against the wall surface of the concrete structure to be detected, further stabilizing the moving support groove. When detecting the wall surface at a higher position, the user raises the hand-held rod upwards and presses the moving support groove to make the abutting columns and the fixing device stable on the wall surface to be detected. The first motor is controlled by the control display panel to drive the threaded rod to rotate, so as to realize the movement detection of the moving block carrying the steel bar detection probe. When detecting the wall surface at a lower position, the lengthening cone rod is rotated to make the lengthening cone rod extend out of the threaded groove, make the hand-held rod and the lengthening cone rod inclined, and make the second cone head abut against the ground to fix the position of the moving support groove, and then the movement of the detection probe is controlled by the control box display panel to detect the wall surface.

[0029] Working principle
[0030] The user holds the hand-held rod 30 and presses the movable support groove 10 through the hand-held rod 30. The spring 51 pushes the fixing cone 52 outward in the telescopic groove 111. The plurality of fixing cones 52 on the movable support groove 10 simultaneously abut against the wall surface of the concrete structure to be detected until the abutting column 11 abuts against the wall surface of the concrete structure to be detected.

[0031] When detecting the wall surface at a higher position, the user holds the upwardly extended hand-held rod 30 and presses the movable support groove 10 to stabilize the abutting column 11 and the fixing device 50 against the wall surface to be detected. By controlling the display panel of the reality panel, the first motor 41 is driven to rotate the threaded rod 42, thereby realizing the movement detection of the moving block 20 carrying the steel bar detection probe 22. When detecting the wall surface at a lower position, the extended tapered rod 33 is rotated to extend the extended tapered rod 33 out of the threaded groove 32, making the hand-held rod 30 and the extended tapered rod 33 inclined, and making the second tapered head 331 abut against the ground to fix the position of the movable support groove 10. Then, the movement of the detection probe is controlled through the display panel of the control box to detect the wall surface.
