[0021] Beneficial effects:

It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the implementation mode of the present invention.

[0036] implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] It should be noted that the diagrams provided in the following implementation modes only illustrate the basic concept of the present invention in a schematic manner. The diagrams only show the components related to the present invention rather than being drawn according to the number, shape, and size of the components in actual implementation. The form, quantity, and ratio of each component in actual implementation may be arbitrarily changed, and the component layout form may also be more complex.

[0038] A rapid detection device for the perpendicularity of post-inserted bar drilling holes, as Figure 1 shown, includes a test rod 100, an angle measuring device 200 provided on the test rod 100, and a plurality of walking devices 300 provided on the test rod 100; wherein,

[0039] The test rod 100 includes a main rod 110 and a sub-rod 120. The end of the main rod 110 is rotatably connected to the end of the sub-rod 120. The sub-rod 120 is for holding by hand, and the main rod 110 is for inserting into the post-inserted bar hole;

[0040] The angle measuring device 200 includes a cross bar 210 and an angle measurer 220. The cross bar 210 is rotatably mounted on the secondary rod 120, and the angle measurer 220 is mounted between the cross bar 210 and the secondary rod 120. In use, the main rod 110 is inserted into the rebar planting hole, the cross bar 210 is supported on the wall surface, and the angle measurer 220 is used to measure the angle between the cross bar 210 and the secondary rod 120;

[0041] The walking device 300 includes an elastic support 310 and a walking wheel 320. The elastic support 310 is arranged on the main shaft, and the walking wheel 320 is arranged on the elastic support 310. The elastic support 310 is used to support the walking wheel 320 in the rebar planting hole, and the walking wheel 320 rolls in the rebar planting hole. Specifically, the elastic support 310 is a spring piece or a combined structure of a support rod and a spring.

[0042] As an embodiment of the present invention, the angle measurer 220 includes a pointer 221 and a scale plate 222. The scale plate 222 is fixedly connected to the cross bar 210. The cross bar 210 is rotatably mounted on the secondary rod 120 through a hollow shaft. The pointer 221 is mounted on a shaft body, and the shaft body is rotatably connected inside the hollow shaft and fixedly connected to the secondary rod 120. By driving the scale plate 222 to rotate around the hollow rotating shaft with the cross bar 210, the relative movement between the scale plate 222 and the pointer 221 is realized, and the rotation angle of the cross bar 210 is measured.

[0043] Hold the secondary rod 120 by hand, insert the main rod 110 into the rebar planting hole, adjust the cross bar 210 to make it close to the wall surface, rotate the secondary rod 120 to drive the secondary rod 120 to slide on the wall surface. The elastic support 310 supports the walking wheel 320 in the rebar planting hole and clings to the hole wall. The walking wheel 320 is used to keep the main rod 110 at the center of the rebar planting hole. When the rebar planting hole is perpendicular to the wall surface, the secondary rod 120 and the cross bar 210 are also perpendicular. At this time, the pointer 221 points to the zero scale of the scale plate 222. When there is an angle between the rebar planting hole and the wall surface, as the secondary rod 120 rotates, an inclination angle will appear between the secondary rod 120 and the cross bar 210. Read the angle indicated by the pointer 221 on the scale plate 222 and record the maximum inclination angle, then the drilling perpendicularity can be quickly judged.

[0044] As an embodiment of the present invention, there are four or more of the walking devices 300. Further, as Figure 2 shown, there are six walking devices 300. The six walking devices 300 are divided into two rows, and three walking devices 300 are arranged in a row. The three walking devices 300 in the same row are circumferentially distributed on the outer periphery of the main rod 110.

[0045] As an embodiment of the present invention, a straight ruler strip 223 is provided on the cross bar 210 for measuring the diameter of the orifice of the rebar planting hole.

[0046] It should be noted that, despite the support of the walking device 300, the main rod 110 will still deviate from the center of the rebar planting hole under its own gravity, resulting in inaccurate measurement. Methods to improve accuracy include installing more walking devices 300 or increasing the elastic force of the elastic support 310; installing more walking devices 300 will increase its own weight and reduce portability and operation flexibility. Increasing the elastic force of the elastic support 310 will increase the resistance when the main rod 110 is inserted into the rebar planting hole, and excessive elastic force may also damage the orifice of the rebar planting hole during insertion; please refer to Figure 2-4, the inventor designed an elastic adjustment device 400 in combination with the principle of using high-pressure air to clean the rebar planting holes in the rebar planting drilling process; as an implementation manner of the present invention, an elastic adjustment device 400 is provided on the main rod 110, and the elastic adjustment device 400 is connected to the elastic support 310 for adjusting the elastic force of the elastic support 310; specifically, the elastic adjustment device 400 includes a pneumatic telescopic rod 410, a connection head 420, a connecting rod 430, a vacuum generator 440, an air inlet pipe 450, a negative pressure air pipe 460, and a valve 470; an installation groove is formed on the main rod 110, the pneumatic telescopic rod 410 is installed in the installation groove, a connection head 420 is provided at the end of the pneumatic telescopic rod 410, one end of a connecting rod 430 is hinged to the connection head 420, the other end of the connecting rod 430 is hinged to the elastic support 310, the vacuum generator 440 is installed on the main rod 110, the air inlet of the vacuum generator 440 is connected to an air inlet pipe 450, the air inlet pipe 450 is used to connect to an external high-pressure air source, and a valve 470 for controlling air intake is provided on the air inlet pipe 450. One end of the negative pressure air pipe 460 communicates with the pneumatic telescopic rod 410, and the other end communicates with the negative pressure port of the vacuum generator 440. In order to prevent the air inlet pipe 450 from affecting the free rotation of the cross bar 210 and reduce the self-weight of the main rod 110 and the auxiliary rod 120, the main rod 110 and the auxiliary rod 120 are of a hollow tubular structure, and the main rod 110 and the auxiliary rod 120 are communicated. The air inlet pipe 450 penetrates through the main rod 110, extends from the inside of the main rod 110 to the inside of the auxiliary rod 120, and passes out from the top of the auxiliary rod 120. The air inlet pipe 450 is rotatably connected to the auxiliary rod 120, so that the auxiliary rod 120 can rotate to any angle without interference. When in use, the air inlet pipe 450 is connected to an external high-pressure air source. During detection, the elastic force of the elastic support 310 is small, which is convenient for inserting into the rebar planting hole. After insertion, the valve 470 is opened, and high-speed gas enters the vacuum generator 440, generating negative pressure at the negative pressure port. Through the negative pressure air pipe 460, the pneumatic telescopic rod 410 contracts, and the pneumatic telescopic rod 410 presses against the elastic support 310 through the connecting rod 430, increasing the supporting force between the main rod 110 and the rebar planting hole, thereby reducing the problem that the main rod 110 deviates from the center of the rebar planting hole under the action of its own gravity and making the measurement more accurate. At the same time, an air outlet pipe 480 is connected to the exhaust port of the vacuum generator 440, and the lower end of the air outlet pipe 480 is arranged at the bottom of the main rod 110. During operation, the exhausted air can blow out the dust particles in the rebar planting hole, realizing the measurement of perpendicularity while cleaning the hole, reducing the process steps and shortening the construction time of rebar planting drilling.

[0048] S1: Use a spoon and a brush to clean out the large pieces of gravel in the rebar planting hole;

[0049] S2: Align the main rod 110 with the rebar planting hole and slowly insert it, allowing the walking wheels 320 to slowly roll on the wall of the rebar planting hole until the cross bar 210 supports on the surface of the opening structure;

[0050] S3: Connect the air inlet pipe 450 to an external high-pressure gas source, open the valve 470 to make the vacuum generator 440 work, and reduce the deviation of the main rod 110 under the action of its own gravity;
