[0020] Such as Figures 1-8As shown in the figure, the technical solution adopted by the present invention is as follows: a detection device for building foundation pit engineering. It includes a vehicle body 1. Two sets of winding components are symmetrically arranged on the vehicle body 1. A cable 11 is wound on each set of winding components.

[0021] Specifically, the winding component includes: a fixed frame 9 and a driving roller 10.

[0028] The bolts 15 correspond to the limiting plates 16 one by one and are respectively rotatably connected to the corresponding limiting plates 16. The bolts 15 are threadedly connected to the bracket 14. Rotating the bolts 15 can adjust the distance between the two limiting plates 16, so that the two limiting plates 16 clamp or loosen the measuring tube pre-installed in the foundation pit.

[0029] Two guiding components corresponding to the winding components one by one are installed on the vehicle body 1. The free end of the cable 11 passes through the guiding component and is connected to the measuring instrument 12.

[0030] Specifically, the guiding component includes: a moving plate 25 and a moving frame 26.

[0031] Among them, a guiding groove is formed on the vehicle body 1, and the moving plate 25 is slidably connected to the guiding groove. The moving frame 26 is fixedly connected to the moving plate 25. The moving frame 26 is located above the vehicle body 1, and an arc-shaped slot is fixedly installed at the upper end of the moving frame 26.

[0035] Specifically, the first driving component includes: a rotating rod 19, a clamping rod 22, a clamping rod 22 and a clamping groove plate 23.

[0036] Among them, the axis of the rotating rod 19 is arranged in the vertical direction. The rotating rod 19 is rotatably connected to the vehicle body 1. One end of the transmission roller 10 is fixedly installed with a first bevel gear 18. The upper end of the rotating rod 19 is fixedly installed with a second bevel gear 20 meshing with the first bevel gear 18.

[0037] The transmission member 21 is installed in the vehicle body 1. Specifically, the transmission member 21 includes a driving wheel, a driven wheel and a synchronous belt. The driving wheel is fixedly connected to the lower end of the rotating rod 19. The driven wheel is rotatably connected to the vehicle body 1.

[0039] The clamping rod 22 is located in the clamping groove plate 23 and is slidably connected to the clamping groove plate 23. A clamping block 24 is fixedly installed at the end of the clamping groove plate 23, and the clamping block 24 is slidably connected to the moving plate 25.

[0040] When the driving roller 10 rotates to wind the cable 11, the rotation of the driving roller 10 drives the transmission member 21 to work through the meshing of the first bevel gear 18 and the second bevel gear 20, that is, the driven wheel on the transmission member 21 drives the clamping rod 22 to rotate together. When the clamping rod 22 rotates, through the cooperation of the clamping groove plate 23, the clamping block 24 and the moving plate 25, the moving plate 25 is driven to slide left and right along the guiding groove. During the left and right sliding of the moving plate 25, the moving frame 26 is simultaneously driven to move left and right reciprocally. Since the cable 11 passes through the arc-shaped slot of the moving frame 26, the cable 11 is driven to move left and right during the left and right movement of the moving frame 26. Cooperating with the rotation of the driving roller 10, the cable 11 is evenly wound on the driving roller 10.

[0041] Two inkjet components are slidably installed in the vehicle body 1.

[0042] Specifically, a lead screw 36 is rotatably installed in the vehicle body 1. The axis of the lead screw 36 is arranged in the horizontal direction. Two moving blocks 37 are threadedly connected to the lead screw 36. Each moving block 37 is fixedly installed with a spray head 34. The two moving blocks 37 are threadedly connected to the lead screw 36 in opposite directions. A second motor 35 for driving the rotation of the lead screw 36 is installed on the lead screw 36.

[0043] The inkjet component includes: an ink tank 38, a connecting frame 31, a hose 33 and a pressing plate 30.

[0044] Among them: the ink tank 38 is fixed in the vehicle body 1.

[0045] The connecting frame 31 is fixedly installed in the vehicle body 1. An airbag 32 is installed in the connecting frame 31. The airbag 32 is communicated with the ink tank 38. A one-way valve is installed between the airbag 32 and the ink tank 38.

[0046] The hose 33 is installed between the airbag 32 and the spray head 34 and communicates the connecting frame 31 and the spray head 34.

[0047] The pressing plate 30 is slidably connected to the connecting frame 31.

[0048] The pressing plate 30 reciprocates in the connecting frame 31 to reciprocally press the airbag 32. When the airbag 32 is pressed, the ink in the airbag 32 is ejected from the spray head 34. When the airbag 32 resets, the one-way valve sucks the ink in the ink tank 38 into the airbag 32.

[0049] A driving structure for driving the inkjet component to inkjet is installed between the inkjet component and the vehicle body 1. Specifically, the driving structure is connected to the pressing plate 30, and the driving structure drives the pressing plate 30 to reciprocate.

[0050] The driving structure includes: a rotating plate 28, a hinged plate 29, a cylinder 2, a first motor 7, and a docking member 8.

[0051] Among them: a vertical shaft is fixedly installed in the middle of the rotating plate 28. A first docking head 27 is fixedly installed at the upper end of the vertical shaft.

[0052] Two hinged plates 29 are provided and are respectively rotatably installed at both ends of the rotating plate 28. One end of the hinged plate 29 away from the rotating plate 28 is rotatably connected to the pressing plate 30.

[0053] The cylinder 2 is fixedly installed on the vehicle body 1, and the telescopic shaft of the cylinder 2 telescopically moves in the vertical direction. A toothed plate 3 is fixedly installed at the end of the telescopic shaft of the cylinder 2.

[0054] A fixed plate 4 is fixedly installed on the vehicle body 1. A gear 5 meshing with the toothed plate 3 is rotatably installed on the fixed plate 4. A turntable 6 is fixedly installed on the output shaft of the gear 5. The first motor 7 is fixedly installed on the turntable 6, and the motor shaft of the first motor 7 is arranged along the radial direction of the turntable 6.

[0055] The docking member 8 cooperates with the first docking head 27. The docking member 8 is fixedly installed on the motor shaft of the first motor 7.

[0056] When the cylinder 2 expands and contracts, it can drive the first motor 7 and the docking member 8 to rotate through the cooperation of the toothed plate 3 and the gear 5. When the docking member 8 rotates to face the first docking head 27, the docking member 8 and the first docking head 27 are connected. Subsequently, the first motor 7 is started, and the first motor 7 drives the rotating plate 28 to rotate. The rotation of the rotating plate 28 drives the two pressing plates 30 to reciprocate through the hinged plate 29. Inkjet work is carried out.

[0057] A second docking head cooperating with the docking member 8 is installed on each transmission roller 10. When the docking member 8 rotates to face the second docking head, the first motor 7 drives the transmission roller 10 to rotate through the docking member 8 and the second docking head. In addition, a motor can also be directly arranged on the transmission roller 10, and the motor starts to rotate forward and backward to drive the transmission roller 10 to rotate forward and backward, realizing the unwinding operation and winding operation of the cable 11 on the transmission roller 10.

[0058] The specific usage method of this application is as follows: Move the vehicle body 1 to the foundation pit measurement location.

[0059] When water level measurement is required, take out the water level gauge of the cable 11 from the placement cylinder 13 and put it into the pre-buried measurement pipe.

[0060] Subsequently, place the bracket 14 on the surface of the measurement pipe. Rotate the bolt 15 to drive the limit plate 16 to move to clamp the measurement pipe. After completing the above work, start the measurement.

[0061] When the measurement is completed and the cable 11 needs to be wound up, the cylinder 2 is started. The cylinder 2 drives the toothed plate 3 to move. The toothed plate 3 drives the gear 5 to rotate. At the same time, the gear 5 drives the first motor 7 on one side of the turntable 6 to rotate.

[0062] When the docking member 8 faces the second docking head, the docking member 8 is snapped into the second docking head. Subsequently, the docking member 8 and the second docking head can be fixed with screws.

[0063] Start the first motor 7 to drive the driving roller 10 to rotate, so as to wind up the cable 11.

[0064] During the process of the driving roller 10 winding up the cable 11, the rotation of the driving roller 10 drives the transmission member 21 to work through the meshing of the first bevel gear 18 and the second bevel gear 20. That is, the driven wheel on the transmission member 21 drives the clamping rod 22 to rotate together. When the clamping rod 22 rotates, through the cooperation of the clamping groove plate 23, the clamping block 24 and the moving plate 25, the moving plate 25 is driven to slide left and right along the guide groove. During the process of the moving plate 25 sliding left and right, the moving frame 26 is driven to move left and right reciprocally together. Since the cable 11 passes through the arc-shaped through hole of the moving frame 26, the cable 11 is driven to move left and right during the left and right movement of the moving frame 26, and in cooperation with the rotation of the driving roller 10, the cable 11 is evenly wound around the driving roller 10.

[0065] When inclinometer detection is required, the inclinometer is placed into the pre-buried measuring tube, and the subsequent process is the same as that of water level monitoring. Details are not elaborated here.

[0066] When crack monitoring is carried out, the connection between the docking member 8 and the second docking head is loosened. Subsequently, the second motor 35 is started, and the second motor 35 drives the lead screw 36 to rotate. The rotation of the lead screw 36 drives the two moving blocks 37 to move. When the nozzle 34 moves to both sides of the crack, the cylinder 2 is started, and the cylinder 2 drives the first motor 7 to rotate through the meshing of the toothed plate 3 and the gear 5. When the first motor 7 rotates to make the docking member 8 face the first docking head 27, the first docking head 27 is docked with the docking member 8, and similarly, it is fixed with screws.

[0067] Start the first motor 7, the first motor 7 drives the rotating plate 28 to rotate, and through the action of the hinge plate 29, the two pressing plates 30 are driven to slide relative to each other inside the connecting frame 31, repeatedly squeezing the airbag 32. Under the action of the one-way valve, the airbag 32 extracts the ink inside the ink tank 38 when it resets. When the airbag 32 is squeezed, the ink inside the airbag 32 is ejected from the nozzle 34, and the ink is sprayed on both sides of the crack, facilitating the measurement of the subsequent size of the crack.
