[0025] It should be noted that the horizontal driving device 1 can be arranged on a mobile device (eg, a vehicle) so that relevant personnel can drive the cement pipe maintenance equipment to move between different cement pipes.

[0026] It can be understood that the inner pipe water spraying device 2 and the outer pipe water spraying device 4 described in this embodiment cooperate with each other to spray the inside and outside of the cement pipe comprehensively, so that the cement pipe can be fully maintained. Avoid spraying the outer wall (inner wall) alone, which may cause defects such as dry spots and cracks on the inner wall (outer wall). Spraying the inside and outside simultaneously can effectively prevent the occurrence of such problems.

[0027] The visual inspection assembly 3 inside the pipe may include: a mounting plate 31, a rotating device 32, a first visual inspection device 33 and an electrically controlled telescopic waterproof member 34. The mounting plate 31 and the rotating device 32 are respectively arranged on the horizontal driving device 1, the first visual inspection device 33 is arranged on the rotating device 32, the electrically controlled telescopic waterproof member 34 is arranged on the mounting plate 31, and the first visual inspection device 33 is arranged in the electrically controlled telescopic waterproof member 34. The visual inspection assembly 5 outside the pipe is arranged on the external water spraying device 4, and the visual inspection assembly 5 outside the pipe is used to inspect the maintenance condition of the outside of the cement pipe.

[0028] It can be understood that the rotating device 32 described in this embodiment can perform visual inspection on various parts in the tube by rotating the first visual inspection device 33.

[0029] It should be noted that the electrically-controlled retractable waterproof member 34 described in this embodiment can provide protection for the first visual inspection device 33 to ensure the accuracy of the inspection by the first visual inspection device 33 .

[0030] Furthermore, if Figure 4 and Figure 5 As shown, the electrically controlled telescopic waterproof member 34 may include: a plurality of electrically controlled telescopic rods 341, a circular plate 342, and a waterproof cloth cover 343. The plurality of electrically controlled telescopic rods 341 are respectively arranged on the mounting plate 31, the circular plate 342 is arranged at the driving end of the electrically controlled telescopic rod 341, one end of the waterproof cloth cover 343 is fixedly arranged on the mounting plate 31, and the other end of the waterproof cloth cover 343 is fixedly arranged on the circular plate 342.

[0031] It is understandable that the waterproof cloth cover 343 described in this embodiment can be stretched and folded according to the extension and contraction of the driving end of the electric telescopic rod 341. It should be noted that the waterproof cloth cover 343 can be replaced by a waterproof member with a telescopic structure (for example, a telescopic sleeve, etc.).

[0032] In order to clearly explain the above embodiment, in one embodiment of the present invention, as Figure 5As shown, the rotating device 32 may include: a fixed plate 321, a movable plate 322, a rack 323, a first motor 324 and a driving wheel 325, wherein the fixed plate 321 is arranged on the horizontal driving device 1, the movable plate 322 is rotatably arranged on the fixed plate 321, the rack 323 is fixedly arranged on the movable plate 322, the first motor 324 is arranged on the horizontal driving device 1, the driving wheel 325 is arranged at the driving end of the first motor 324, and the driving wheel 325 and the rack 323 are engaged with each other, wherein the first visual detection device 33 is arranged on the movable plate 322.

[0033] It should be noted that a limiting groove (for example, an annular groove with a T-shaped cross section) may be provided on the fixed plate 321 described in this embodiment, and a limiting slider (for example, an annular slider with a T-shaped cross section) may be fixedly provided on the movable plate 322, and the limiting slider can rotate in the limiting groove.

[0034] In one embodiment of the present invention, Figure 3-Figure 5 As shown, the in-pipe water spraying device 2 may include: a first spraying bin 21 and a plurality of first spraying heads 22, the first spraying bin 21 is arranged on the horizontal driving device 1, and the first spraying bin 21 is annular, and a plurality of first spraying heads 22 are arranged on the side wall of the first spraying bin 21. The out-pipe water spraying device 4 may include: a plurality of local spraying devices 41, the local spraying device 41 includes: a second spraying bin 411 and a plurality of second spraying heads 412, wherein the second spraying bin 411 is arranged on the horizontal driving device 1, and a plurality of second spraying heads 412 are respectively arranged on the side walls of the second spraying bin 411.

[0035] It can be understood that the first spray chamber 21 and the second spray chamber 411 described in this embodiment can be connected to an external water delivery device (for example, a water pump assembly) to enable the corresponding spray heads to spray water.

[0036] It should be noted that the shapes and sizes of the multiple second spray chambers 411 described in this embodiment can be modified according to actual needs (for example, second spray chambers 411 of different sizes can be customized according to the size of the cement pipe).

[0037] like Figure 5 , Figure 6 and Figure 7 As shown, the outer tube visual inspection component 5 may include: multiple local inspection devices 51, multiple local spray devices 41 and multiple local inspection devices 51 correspond one to one, the local inspection device 51 may include: an electric push rod 511, a sealing plate 512 and a second visual inspection device 513, the second spray chamber 411 is provided with a mounting groove, the electric push rod 511 is arranged in the mounting groove, the sealing plate 512 is arranged on the driving end of the electric push rod 511, and the second visual inspection device 513 is arranged on the sealing plate 512.

[0038] It can be understood that the electric push rod 511 described in this embodiment can seal the installation groove through the sealing plate 512, which can provide protection for the second visual detection device 513 and ensure the accuracy of the detection of the second visual detection device 513.

[0039] It should be noted that the first visual detection device 33 and the second visual detection device 513 are both visual sensors with built-in lighting.

[0040] Specifically, relevant personnel first connect the external water delivery equipment to the first spray tank 21 and the second spray tank 411, and move the maintenance equipment to the target cement pipe by vehicle. The horizontal driving device 1 can drive the water spraying device 2 inside the pipe, the visual inspection component 3 inside the pipe, the water spraying device 4 outside the pipe, and the visual inspection component 5 outside the pipe to move horizontally and approach the target cement pipe.

[0041] If the cement pipe needs to be inspected before spraying, the electric push rod 511 pushes the sealing plate 512 away from the installation slot to move the second visual inspection device 513 out of the installation slot. Under the joint inspection of multiple mobile local inspection devices 51, the outside of the cement pipe can be visually inspected. The driving end of the electric telescopic rod 341 retracts to squeeze and fold the waterproof cloth cover 343, and the waterproof cloth cover 343 no longer protects and blocks the first visual inspection device 33. In the process of the horizontal driving device 1 moving the visual inspection component 3 in the pipe, the first motor 324 drives the driving wheel 325 to rotate, and the driving wheel 325 drives the movable plate 322 to rotate on the fixed plate 321 through the rack 323. The first visual inspection device 33 can be used to visually inspect the inside of the pipe. By performing visual inspection before spraying, cement pipes with obvious defects, such as cracks, pores, irregular shapes, etc., can be discovered and removed early. This can avoid sending defective products to subsequent processes and save maintenance costs and time.

[0042] When spraying starts, the sealing plate 512 and the waterproof cloth cover 343 are reset, and the horizontal drive device 1 drives the first spray chamber 21 and the second spray chamber 411 to move. The multiple first spray heads 22 on the first spray chamber 21 spray water to spray the inside of the pipe, and the multiple second spray heads 412 on the second spray chamber 411 spray water to spray the outside of the pipe. After the spraying is completed, the first visual inspection device 33 and the second visual inspection device 513 can be used for another spraying inspection. Through two inspections before and after the spraying, it is possible to more accurately judge whether there is a problem with the cement pipe, and through the coordination of the inspection results inside and outside the pipe, a comprehensive judgment can be made on whether there is a problem with the cement pipe, which is convenient for cleaning defective products. During the spraying process or the movement of the cement curing device, the sealing plate 512 can protect the second visual inspection device 513 (the waterproof cloth cover 343 can protect the first visual inspection device 33), thereby improving the service life of the visual inspection device and the accuracy of the inspection.

[0043] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the horizontal drive device 1 may include: a frame 11, a second motor 12, a first ball screw 13, a first ball slider 14, a driving gear 15 and a plurality of driving members 16, wherein the second motor 12 is arranged on the frame 11, the first ball screw 13 is arranged on the driving end of the second motor 12, the first ball slider 14 is arranged on the first ball screw 13, the in-pipe water spraying device 2 and the in-pipe visual detection component 3 are respectively arranged on the first ball slider 14, the driving gear 15 is arranged on the first ball screw 13, and a plurality of driving members 16 are respectively connected to the driving gear 15, wherein the first motor 324, the fixing plate 321, the mounting plate 31 and the first spray chamber 21 are respectively arranged on the first ball slider 14.

[0044] The plurality of driving members 16 correspond to the plurality of local detection devices 51 one by one, and the driving member 16 may include: a second ball screw 161, a second ball slider 162, a driven wheel 163 and a transmission toothed belt 164, wherein the second ball screw 161 is rotatably arranged on the frame plate 11, the second ball screw 161 is connected to the local detection device 51 through the second ball slider 162, the driven wheel 163 is arranged on the second ball screw 161, and the driven wheel 163 is connected to the driving gear 15 through the transmission toothed belt 164. The second spray chamber 411 is arranged on the second ball slider 162.

[0045] It should be noted that the horizontal drive device 1 described in this embodiment adopts multiple ball screw pair structures. When the second motor 12 drives the driving gear 15 (the driving gear 15 is obtained by connecting multiple gears in parallel, and the number of gears corresponds to the driving member 16) to rotate through the first ball screw 13, the first ball slider 14 can move on the rotating first ball screw 13, and the moving first ball slider 14 can drive the mounting plate 31 and the first spray chamber 21 to move horizontally. The driving gear 15 can simultaneously drive multiple second ball screws 161 to rotate through multiple transmission belts 164, and the second ball slider 162 can move on the rotating second ball screw 161, and the moving second ball slider 162 can drive the second spray chamber 411 to move horizontally.
