[0017] like Figure 1-Figure 4As shown, a crack detection device for construction engineering includes a mobile vehicle 1, a telescopic rod 2 and a storage box 3. One side of the mobile vehicle 1 has a plurality of rollers 101, and an ultrasonic detector 4 and a protruding nozzle 5 are arranged inside the side. The ultrasonic detector 4 is used to detect cracks on the wall surface, and the nozzle 5 is used to mark the cracks after they are detected. The other side of the mobile vehicle 1 is rotatably connected to a U-shaped frame 6, one end of the telescopic rod 2 is connected to the U-shaped frame 6, and the other end of the telescopic rod 2 is provided with a connector 7. The design of the telescopic rod 2 can adjust the length according to needs. It is suitable for wall detection at different heights. The telescopic rod 2 has a hollow structure and is provided with a connecting pipe 11. One end of the connecting pipe 11 passes through the U-shaped frame 6 and the mobile vehicle 1 and is finally connected to the nozzle 5. The connecting pipe 11 is connected to the connecting head 7. A paint box 8 and a controller 9 are placed in the storage box 3. A pump 10 is fixedly installed on one side of the paint box 8. The input end of the pump 10 is connected to the bottom of the paint box 8 through a connecting pipe 2 12. The output end of the pump 10 is connected to a connecting pipe 3 13. The end of the connecting pipe 3 13 is detachably connected to the connecting head 7.

[0018] The telescopic rod 2 includes a sleeve 1 201 and a sleeve 202, one end of the sleeve 202 is directly connected to the U-shaped frame 6, and the other end of the sleeve 202 is slidably connected to the sleeve 1 201, and the connector 7 is located on the end of the sleeve 1 201 away from the sleeve 202. The end of the sleeve 1 201 with the connector 7 is fixedly connected with a fixed rod 203, and the fixed rod 203 can be inserted into the sleeve 202, and the end of the fixed rod 203 away from the connector 7 is rotatably connected to the fixed pulley 1 204, and the end of the sleeve 202 close to the sleeve 1 201 is rotatably connected to the fixed pulley 205. The connecting pipe 11 is serpentinely wound on the fixed pulley 1 204 and the fixed pulley 2 205 to adapt to the length change of the telescopic rod 2 when it is extended and retracted, so as to ensure smooth pigment transportation.

[0019] An electric push rod 14 is installed in the mobile vehicle 1, and the spray head 5 is fixedly connected to the telescopic rod 2 of the electric push rod 14. The spray head 5 can be extended and retracted by extending and retracting the telescopic rod 2 of the electric push rod 14.

[0022] One end of the sleeve 201 having the connector 7 is sleeved with an anti-slip sleeve 16 to increase the stability and comfort of the operator when holding the telescopic rod 2.

[0023] Working principle: When in use, the operator connects the connecting pipe 3 13 to the connecting head 7, and then holds the end of the telescopic rod 2 with the anti-slip sleeve 16, and attaches the mobile vehicle 1 to the wall to be detected through the roller 101, and adjusts the length of the telescopic rod 2 as needed. Then, the operator controls the ultrasonic detector 4 to start working through the remote control 901, and then moves the mobile vehicle 1 on the wall by manipulating the telescopic rod 2. The ultrasonic detector 4 performs real-time crack detection on the wall. When the ultrasonic detector 4 detects the position of the crack on the wall, the prompt light 15 lights up to remind the operator to stop moving the mobile vehicle 1, and then controls the telescopic rod 2 of the electric push rod 14 through the remote control 901 to extend the nozzle 5. Until it is close to the wall, and then the pump 10 is controlled to start by the remote control 901. The pump 10 pumps the paint in the paint box 8 to the nozzle 5 through the connecting pipe 1 11, the connecting pipe 2 12 and the connecting pipe 3 13 for spraying, thereby marking the crack. After the marking is completed, the operator controls the telescopic rod 2 of the electric push rod 14 to retract and controls the pump 10 to close through the remote control 901, and continues to move the mobile vehicle 1 to the next detection position by operating the telescopic rod 2. Repeat the above steps until all positions on the wall are detected. After the detection is completed, the operator controls the ultrasonic detector 4 to close through the remote control 901, and disconnects the connecting pipe 3 13 from the connector 7, and then restores the telescopic rod 2 to its initial state.
