Description

Technical Field

[0001] The utility model specifically relates to an adsorption-type steel bar protective layer detection tool vehicle, belonging to the technical field of steel bar protective layer detection. Background Art

[0002] The steel bar protective layer is the distance from the outer edge of the outermost steel bar to the concrete surface. In order to protect the steel bars from rust and ensure the structural strength of the concrete building structure, a third party will generally test the thickness of the protective layer through a steel bar protective layer detector after the construction is completed. The staff will hold the detector and move along the concrete surface, and detect the thickness of the protective layer through the detection coil in the detector. The steel bar protective layer detection is completed by a steel bar protective layer measuring instrument, such as the Chinese patent announcement number: CN217820287U, which discloses an adsorption-type steel bar protective layer detection tool vehicle. By controlling the fan, the wall-climbing remote control vehicle body is adsorbed on the wall, and then the steel bar protective layer on the wall can be detected through the steel bar protective layer detector probe. However, the surface of the building structure is not smooth, and sand is easily adhered to the surface during mortar painting. When the detection vehicle passes through the sand, the wheels are easily pushed outward. Since the distance between the detector and the steel bar protective layer is affected by the wheels, the detection accuracy of the tool vehicle cannot be guaranteed. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes an adsorption-type steel bar protective layer detection tool vehicle, which can monitor the walking state of the wheel on the surface of the steel bar protective layer and can correct the detection accuracy of the tool vehicle.

[0004] The utility model of the adsorption type steel bar protective layer detection tool vehicle comprises:

[0005] A vehicle body, wherein a detector body is fixed inside the vehicle body, and a detection end of the detector body faces the bottom surface of the vehicle body; stress-bearing grooves are provided at both ends of the top surface of the vehicle body; and a swing seat is fixed in the middle of the top surface of the vehicle body;

[0008] The tilt detection unit includes a distance measuring transmitter embedded in both ends of the top surface of the outer detection seat; the distance measuring transmitter and the detector body are connected to the controller, and the controller is connected to the detection terminal;

[0009] Due to the action of the first spring body, the wheels at both ends of the vehicle body can always be pressed against the outer surface of the steel bar protective layer; and when the handshake pushes the external detection seat, since the handshake and the hinge axis are on the same vertical line, the handshake will not cause the external detection seat to tilt to one side; when the wheel of the vehicle body passes through the protruding position of the steel bar protective layer, the wheel of the vehicle body is subjected to force, pushing the vehicle body outward, compressing the first spring body, so that the vehicle body and the external detection seat form a stable tilted state; during detection, the wheels of the vehicle body are pressed against the steel bar protective layer through the handshake, and then the vehicle body is pushed to move; during walking, the protective layer thickness is obtained in real time through the detector body, and the detection data is sent to the controller. At the same time, the tilt detection unit works to obtain the distance measurement data through two distance measurement transmitters, that is, the distance between the distance measurement transmitter and the external detection seat is obtained respectively, and the two distance measurement data are differentially measured. When the difference is greater than the set value, it is determined that the wheel of the vehicle body is pushed outward. At this time, the data detected by the detector body is determined to be invalid data; when the difference is less than the set value, it is assumed to be valid data, and the data correction process is entered. During correction, since the installation distance between the distance measuring transmitters is a fixed value, the difference between the two distance measuring data is a fixed value, and the inclination angle of the vehicle body can be calculated by the Pythagorean theorem; and the correction data is obtained according to the inclination angle, that is, the corresponding error data of the vehicle body under various inclination angles is tested in advance; an error correction table is established, and after the controller obtains the real-time inclination angle, the corresponding error data is obtained as the correction data by looking up the error correction table; the controller obtains the detection data through the detector body, and performs difference calculation between the detection data and the error data to obtain the corrected protective layer thickness data.

[0010] Furthermore, the detection terminal is engaged and fixed with the external detection seat.

[0011] Furthermore, a blind hole is axially opened inside the handshake, a telescopic rod is embedded in the blind hole, and the detection terminal is wirelessly connected to the controller; the detection terminal is hung on the telescopic rod; when the high-position steel bar protective layer is detected, the telescopic rod is embedded into the inner side of the handshake to realize the movable engagement and limiting of the telescopic rod and the handshake.

[0012] Furthermore, a tail post is embedded in one end of the telescopic rod away from the blind hole; a through hole is opened in the circumference of the tail post, and a support rod is movably passed through the through hole, a walking wheel is installed at the bottom of the support rod, and a limiting nut is screwed on the other end of the support rod; a second spring body is arranged between the walking wheel and the tail post of the support rod; when the high-position steel bar protective layer is detected, the tail post is embedded in the bottom of the telescopic rod and locked by bolts, and then the wheel body of the vehicle body and the walking wheel of the support rod are attached to the steel bar protective layer; then, the telescopic rod is pressed to make the wheel body of the vehicle body fit with the steel bar protective layer, and at the same time, the other end of the telescopic rod is elastically supported and adapted by the second spring body; then, the telescopic rod is pushed to move forward, and during the movement, the detector body can continuously detect the steel bar protective layer.

[0013] Furthermore, the bottom of the vehicle body is an inverted concave structure, and an adsorption hood is provided at the concave part of the vehicle body; the adsorption hood is connected to a vacuum pump group; when the steel bar protective layer is detected, the vacuum pump group is turned on to enable the vehicle body to be close to the surface of the adsorbed steel bar protective layer.

[0014] Furthermore, guide bearings are embedded and fixed at both ends of the swing seat, and the hinge shaft and the guide bearings are rotatably installed, so that the swing seat can swing smoothly through the guide bearings.

[0015] Furthermore, the distance measuring transmitter is arranged between the swing seat and the first spring body; the distance between the two distance measuring transmitters and the axis center line of the hinge shaft is equal; the distance measuring transmitter collects the distance data between the vehicle body and the external detection seat in real time, and transmits the distance data to the controller; the inclination angle is calculated by the controller.

[0016] Compared with the prior art, the adsorption-type steel bar protective layer detection tool vehicle of the utility model sets the vehicle body as a free swinging structure, which can adapt to the surface of the steel bar protective layer, and adopts a ranging transmitter to monitor the swing inclination angle of the vehicle body in real time; the walking state of the wheels on the surface of the steel bar protective layer is monitored in real time, the detection data with too large inclination angle is eliminated, and the detection data with small inclination angle is corrected twice, so as to ensure the detection accuracy of the detection tool vehicle on the steel bar protective layer.
