Therefore, it should not be construed as a limitation to the present utility model.

[0024] The present utility model will be further described below with reference to the accompanying drawings:

[0025] As Figures 1-5 shown, a non-destructive testing device for pipeline welds includes a magnetic adsorption trolley. A detection mechanism is arranged on the upper side of the magnetic adsorption trolley, and a cleaning mechanism is arranged at the front end of the magnetic adsorption trolley. The magnetic adsorption trolley is arranged on the steel pipeline 4 by means of magnetic force. The weld to be tested 401 on the steel pipeline 4 is aligned with the detection mechanism. The magnetic adsorption trolley includes a vehicle frame 101. A vehicle shell 102 is fixedly connected to the upper part of the vehicle frame 101. A driving motor 103 is fixedly connected to the rear side of the vehicle shell 102. The output end of the driving motor 103 is fixedly connected with a first bevel gear 104. A second bevel gear 105 is engaged with one side of the first bevel gear 104. The upper part of the rear end of the vehicle frame 101 is rotatably connected with a transmission shaft 106. The middle of the transmission shaft 106 is fixedly connected with the second bevel gear 105. Symmetrically arranged driving gears 107 are fixedly connected to both ends of the transmission shaft 106. A support shaft 109 is arranged below the transmission shaft 106. The support shaft 109 is fixedly connected with the vehicle frame 101. Symmetrically arranged wheels 108 are rotatably connected to both ends of the support shaft 109. A gear is arranged on one side of the wheel 108. The driving gear 107 is in gear engagement with the wheel 108. Receiving grooves are arranged at both ends of the support shaft 109. Receiving blocks 110 are slidably connected in the receiving grooves on the support shaft 109. Electromagnets 111 are installed on the receiving blocks 110. Patterns for increasing friction are arranged on the surface of the wheel 108. When the driving motor 103 rotates, it drives the first bevel gear 104 to rotate. The rotation of the first bevel gear 104 drives the second bevel gear 105 to rotate. The rotation of the second bevel gear 105 drives the transmission shaft 106 to rotate. The rotation of the transmission shaft 106 drives the driving gear 107 to rotate. The rotation of the driving gear 107 drives the wheel 108 to rotate. The arrangement of the patterns on the wheel 108 can provide stronger grip for the magnetic adsorption trolley. The rear wheel 108 drives the magnetic adsorption trolley and other components thereon to move forward. The front wheel 108 moves under forced motion. When the electromagnet 111 is started, it generates magnetic force, causing the magnetic adsorption trolley to adsorb on the steel pipeline 4. In this way, the magnetic adsorption trolley can move annularly around the weld to be tested 401 on the steel pipeline 4.

[0026] The detection mechanism includes a control and processing platform 201 fixedly connected to the vehicle shell 102. One end of the control and processing platform 201 is fixedly connected to a first telescopic rod 202. The output end of the first telescopic rod 202 is fixedly connected to a second telescopic rod 203. The output end of the second telescopic rod 203 is fixedly connected to a detection head 204. A data connector 205 is fixedly connected to the control and processing platform 201. The data connector 205 is externally connected to a detection device controller through a data cable. The detection device controller can control the detection device and display the detection data. After the magnetic adsorption trolley is adsorbed on the steel pipe 4, the operator uses the detection device controller to control the detection mechanism. The first telescopic rod 202 expands and contracts to drive the second telescopic rod 203 to move axially, and the second telescopic rod 203 expands and contracts to drive the detection head 204 to move radially, so that the detection head 204 is aligned with the weld 401 to be measured, and thus the weld 401 to be measured can be nondestructively detected.

[0027] The cleaning mechanism includes a cleaning bracket 301 hinged to the front end of the vehicle frame 101. A transmission gear 302 is rotatably connected to the cleaning bracket 301. The lower side of the transmission gear 302 meshes with the gear on the front wheel 108. One side of the transmission gear 302 is fixedly connected to a driving pulley 303. The driving pulley 303 is rotatably connected to the cleaning bracket 301. A cleaning shaft 306 is rotatably connected to the front end of the cleaning bracket 301. Symmetrically arranged driven pulleys 305 are fixedly connected to both ends of the cleaning shaft 306. The driving pulley 303 and the driven pulleys 305 are connected and driven by a belt 304. A cylindrical wire brush 307 is fixedly connected to the middle of the cleaning shaft 306. After the operator adsorbs the magnetic adsorption trolley onto the steel pipe 4, the cleaning bracket 301 is adjusted to make the cylindrical wire brush 307 contact the surface of the steel pipe 4. The front wheel 108 is forced to rotate, driving the transmission gear 302 to rotate. The rotation of the transmission gear 302 drives the driving pulley 303 to rotate. The rotation of the driving pulley 303 drives the belt 304 to move. The movement of the belt 304 drives the driven pulleys 305 to rotate. The rotation of the driven pulleys 305 drives the cleaning shaft 306 to rotate. The rotation of the cleaning shaft 306 drives the cylindrical wire brush 307 to rotate. The rotation direction of the cylindrical wire brush 307 is opposite to the rotation direction of the wheel 108, so that the sundries cleaned will not enter under the magnetic adsorption trolley and affect the forward movement of the magnetic adsorption trolley.

[0028] The control and processing platform 201 is electrically connected to the driving motor 103, the first telescopic rod 202, the second telescopic rod 203, and the detection head 204. The movements of the driving motor 103 and the first telescopic rod 202 can be controlled through the control and processing platform 201. The monitoring data collected by the detection head 204 is transmitted back to the control and processing platform 201 for processing, and the processing result is sent to the detection device controller through the data connector 205.

[0029] Working principle: The operator activates the electromagnet 111 to generate magnetic force to adsorb the detection device on the steel pipe 4. The detection mechanism is activated to align the detection head 204 with the weld to be detected 401. The drive motor 103 is activated to make the detection device move circularly along the weld to be detected 401. During the movement of the detection device, the cylindrical wire brush 307 rotates to clean up the debris during the movement of the detection device, avoiding affecting the detection effect. The non-destructive testing of the weld is completed during the circular movement of the detection device.

[0030] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
