Description

Technical Field

[0001] The invention belongs to the field of cement pipe maintenance, in particular to a cement pipe maintenance device. Background Art

[0002] Cement pipe is a pre-set pipe made of cement and steel bars using the centrifugal force of electric poles. It is generally used for rainwater and sewage discharge pipes in cities and towns. It can be used as an outer casing for underground pipelines such as tap water, electricity, telecommunications, and gas.

[0003] A patent application with publication number CN118003452A discloses a cement pipe maintenance equipment, including: a vehicle body and a maintenance mechanism, the maintenance mechanism is arranged at the front end of the vehicle body, the maintenance mechanism includes a lifting component and a spray mechanism, the spray mechanism includes an outer spray assembly and an inner spray assembly, the inner spray assembly includes three groups of first roller brush components, an inner spray pipe and two groups of support components. The present invention effectively solves the problem that the bottom side of the pipe body is not easy to contact with water, there is a spray dead angle, and the pipe body cannot be fully maintained.

[0004] Cement pipes are generally stored in stacks outdoors. Traditional wet curing equipment is relatively simple in function. It simply sprays water on the stacked cement pipes, which can easily cause problems with inadequate spraying. Or it uses an overly complex structure to lift each cement pipe one by one for wetting. The stacked cement pipes are not only heavy, but the cement pipes at the bottom can basically not be lifted for curing.

[0005] To this end, the present invention provides a cement pipe maintenance device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a cement pipe maintenance device described in the present invention comprises a spray sleeve, a plurality of atomizing nozzles are installed at the bottom of the spray sleeve, and the plurality of atomizing nozzles are arranged at equal intervals, and both ends of the spray sleeve are slidably connected with a moving arm, and the end of the moving arm is fixedly connected to a connecting seat, and a support frame is fixedly connected below the connecting seat, and a driving wheel is installed at the bottom of the support frame, and a water tank is fixedly connected to the outside of the support frame, and a transmission pipe is connected between the water tank and the connecting seat, and a spray assembly is arranged on the side of the support frame away from the water tank, and the spray assembly is used to spray water on the inner wall of the cement pipe, and the cement pipe is generally stored in a stacked manner outdoors;

[0008] Through the setting of the spray sleeve, the spray sleeve transfers the water in the water tank to multiple atomizing nozzles through the transmission pipe, the connecting seat and the movable arm. The two support frames raise the spray sleeve upward so that the spray sleeve is located above the stacked cement pipes. At the same time, it is necessary to ensure that the two ends of the cement pipes are facing the support frames. The atomized water source moistens the surface of the cement pipe from top to bottom. Although the cement pipes are stacked, there are still gaps between them. The gradually accumulated water on the top will gradually moisten the outer wall of the cement pipe downward under the action of gravity. Then the spray assembly extends into the middle of each cement pipe to spray the water source into the inner wall of the cement pipe. With the continuous movement of the support frame, the large-area stacked cement pipes can be wet-cured. Through this setting, not only can the large-area cement pipes be effectively collectively maintained, but the overall operation is simple, which reduces errors and failures in the maintenance process.

[0009] Preferably, the spray assembly includes a movable nozzle, the two nozzles are symmetrically arranged, three adjustment nozzles are installed at the front end of the nozzle, the adjustment nozzle can adjust its own water outlet, the nozzle is also connected to the water tank, and a laser transmitting module and a laser receiving module are also arranged at the end of the nozzle. The movable nozzles are symmetrically arranged, and the laser emitted by the laser transmitting module will be received by the laser receiving module after passing through the middle of the cement pipe, so as to determine that the nozzle has arrived at both ends of the cement pipe, so that the nozzle is properly extended into the cement pipe, and a water tank is provided with a water tank. The pump presses the water source into the nozzle. The adjustment nozzle at the end of the nozzle can change the direction. First, the nozzle is adjusted to spray horizontally, and then multiple adjustment nozzles rotate outward to spray from the center of the cement pipe to the outside. When the adjustment nozzle is rotated to a vertical state, the inner wall of the cement pipe can be sprayed. During the continuous spraying process of the atomizing nozzle above, the inner wall of the cement pipe is continuously searched and sprayed. The working time of the two overlaps with each other. When the surface of the cement pipe in one area is wetted, the inner wall of the cement pipe in this area is also completely wetted, ensuring work efficiency.

[0010] Preferably, a plurality of telescopic nozzles are installed at the bottom of the movable arm, and the plurality of telescopic nozzles are arranged equidistantly. Sealing assemblies are installed at both ends of the spray sleeve, and the sealing assemblies are used to seal the two ends of the spray sleeve. In order to adapt to a cement pipe with a longer length, the two support frames are driven to move to both sides by a driving wheel, so that the two movable arms are pulled out of the spray sleeve. When the telescopic nozzle is pulled out of the spray sleeve, the telescopic nozzle will extend downward under the action of an internal spring. When the telescopic nozzle is inside the spray sleeve, the bottom is blocked and water cannot be sprayed. Only after the spray sleeve is removed will the liquid be sprayed outward. The end of the movable arm is open, allowing water to directly enter the spray sleeve, so that the atomizing nozzle can receive the water source. In this way, the length of the equipment can be adjusted to adapt to the length of the cement pipe.

[0011] Preferably, the sealing assembly includes a clamping sleeve, which is fixedly connected to the outside of the spray sleeve, and a vertically arranged sealing plate is slidably clamped in the middle of the clamping sleeve, and an elastic pad is fixedly connected to the top of the sealing plate. An electric telescopic rod is fixedly connected between the upper part of the two ends of the sealing plate and the clamping sleeve, and the sealing plate is driven to move upward by the electric telescopic rod to block the gap between the spray sleeve and the movable arm. The seal of the sealing plate will only be contacted when the movable arm moves outward. The elastic pad is provided to increase the sealing effect.

[0012] Preferably, the support frame is composed of two inclined support arms, a movable rail is arranged between the two support arms, a movable seat is slidably engaged in the movable rail, the movable seat is connected to the nozzle, movable components are arranged at both ends of the movable seat, a base is fixedly connected to the bottom of the movable rail, and the base is fixedly connected to the two support arms. In order to be able to enter cement pipes of different heights, the movable seat is driven to rise and fall by the movable assembly, so that the movable seat can be aligned with different cement pipes, and the entire equipment is driven to move back and forth by the driving wheel, so that the nozzle can be moved to the center position of the cement pipe, and the inner wall spraying and maintenance work can be carried out.

[0013] Preferably, the moving assembly includes a screw and a vertical rod, the screw is transmission-connected to one end of the moving seat, the vertical rod passes through the other end of the moving seat, the screw and the vertical rod are both rotatably engaged with the bottom of the connecting seat, a driving motor for driving the screw to rotate is installed at the bottom of the screw, the driving motor is fixedly connected to the base, the moving seat and the water tank are connected by a hose, the screw is driven to rotate by the driving motor, the lifting and lowering of the moving seat is controlled by forward and reverse rotation, and the moving seat is restricted by the vertical rod and the moving rail so that the moving seat can only move up and down.

[0014] Preferably, the nozzle is composed of an adjustment tube and a plurality of stacked tubes, the plurality of stacked tubes are sleeved with each other, the stacked tube with the largest diameter is fixedly connected to the adjustment tube, the adjustment nozzle is installed at the end of the stacked tube with the smallest diameter, a coil spring is fixedly connected between the two stacked tubes that are farthest apart, the outer side of the adjustment tube is rotatably connected to six dispersion tubes, an electric folding frame is installed between the dispersion tube and the adjustment tube, and a rotating assembly is arranged on the outer side of the adjustment tube, so that the nozzle can partially enter the cement pipe, when the nozzle and the cement pipe are aligned in the center, when the water in the water tank is injected into the adjustment tube and the stacked tubes, the stacked tubes will expand outwards under the action of water pressure, and then the adjustment nozzle is turned on to allow water to spray out from the adjustment nozzle, and the water outlet of the adjustment nozzle The orifice is small, so the water flows out of the outlet faster and can be sprayed a longer distance. At the same time, the thrust for the stacked pipes is also strong enough to stretch the coil spring. When the water pressure stops injecting, the coil spring will pull the multiple stacked pipes to overlap and keep the ends of the stacked pipes away from the cement pipe, so that the nozzle can move normally. At the same time, in the process of adjusting the nozzle, multiple dispersion pipes are unfolded under the action of the electric folding frame, so that the dispersion pipes are directed to the six gaps around the cement pipe; when the cement pipes are stacked, there will be six gaps around them; water is sprayed into them through the dispersion pipes. This process can not only quickly wet the outer wall of the cement pipes accumulated at the bottom, but also the working time overlaps with the working time of adjusting the nozzle, which will not affect the overall working time.

[0015] Preferably, the rotating assembly includes a servo motor, which is fixedly connected to one end of the moving seat away from the water tank, and the output end of the servo motor is fixedly connected to the outside of the adjustment tube. A flexible bellows is fixedly connected between the adjustment tube and the moving seat. The servo motor can drive the stacked tubes and the adjustment tubes to rotate to a horizontal or vertical state, so that the stacked tubes can fit the support frame more closely and will not occupy a large space when the equipment is stored. After each work, the vertical ends of the stacked tubes are pressed against the ground to allow the stacked tubes to overlap, thereby ensuring that the internal coil springs will not be permanently deformed due to long-term work.

[0017] Preferably, the adjustment assembly includes a hydraulic rod, the outer side of the hydraulic rod is fixedly connected to the inner wall of the stacked pipe, and the top of the hydraulic rod is fixedly connected with a friction rod, which passes through the top of the stacked pipe and is transmission-connected to the outer sides of the multiple stacked pipes. By driving the friction rod to move through the hydraulic rod, multiple adjustment nozzles can be rubbed to close to the center or spread outward, and the diffusion amplitude is the same, thereby ensuring that the inner wall of the cement pipe is evenly moisturized by water.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The cement pipe maintenance equipment described in the present invention, through the setting of the spray sleeve, the spray sleeve transfers the water in the water tank to multiple atomizing nozzles through the transmission pipe, the connecting seat and the movable arm, and the two support frames raise the spray sleeve upward so that the spray sleeve is located above the stacked cement pipes.

Although the cement pipes are in a stacked state, there are still gaps between them. The gradually accumulated water on the top will gradually wet the outer wall of the cement pipe downward under the action of gravity, and then the spray component extends into the middle of each cement pipe to spray the water source into the inner wall of the cement pipe. With the continuous movement of the support frame, the cement pipes stacked in a large area can be wet-cured. Through this arrangement, not only can the large-area cement pipes be effectively collectively maintained, but the overall operation is simple, which reduces the mistakes and failures in the maintenance process.

[0020] 2. In the cement pipe maintenance equipment described in the present invention, the laser emitted by the laser transmitting module will be received by the laser receiving module after passing through the middle of the cement pipe, so as to determine that the nozzle has reached the two ends of the cement pipe, so that the nozzle is properly extended into the cement pipe. A water pump is provided in the water tank to press the water source into the nozzle. The adjustment nozzle at the end of the nozzle can change its direction. First, the nozzle is adjusted to spray horizontally, and then multiple adjustment nozzles are rotated outward to spray from the center of the cement pipe to the outside. When the adjustment nozzle is rotated to a vertical state, the inner wall of the cement pipe can be sprayed. During the continuous spraying process of the atomizing nozzle above, the inner wall of the cement pipe is continuously searched and sprayed. The working time of the two overlaps with each other. When the cement pipe surface in one area is completely wetted, the inner wall of the cement pipe in this area is also completely wetted, thereby ensuring work efficiency.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4 As shown, a cement pipe maintenance device according to an embodiment of the present invention comprises a spray sleeve 1, a plurality of atomizing nozzles 14 are installed at the bottom of the spray sleeve 1, and the plurality of atomizing nozzles 14 are arranged equidistantly, and both ends of the spray sleeve 1 are slidably connected with a moving arm 2, and the end of the moving arm 2 is fixedly connected to a connecting seat 5, and a support frame 3 is fixedly connected below the connecting seat 5, and a driving wheel 7 is installed at the bottom of the support frame 3, and a water tank 6 is fixedly connected to the outer side of the support frame 3, and a transmission pipe 8 is connected between the water tank 6 and the connecting seat 5, and a spray assembly is arranged on the side of the support frame 3 away from the water tank 6, and the spray assembly is used to spray water to the inner wall of the cement pipe;

[0032] During operation, cement pipes are generally stored in stacks outdoors. Traditional wet curing equipment is relatively simple in function. It simply sprays water on the stacked cement pipes, which can easily cause problems with inadequate spraying. Alternatively, too complex a structure is used to lift each cement pipe one by one for wetting. The stacked cement pipes are not only heavy, but the cement pipes at the bottom are basically impossible to lift for curing.

[0033] Through the setting of the spray sleeve 1, the spray sleeve 1 transfers the water in the water tank 6 to the multiple atomizing nozzles 14 through the transmission pipe 8, the connecting seat 5 and the movable arm 2. The two support frames 3 raise the spray sleeve 1 upward so that the spray sleeve 1 is located above the stacked cement pipes. At the same time, it is necessary to ensure that the two ends of the cement pipes are facing the support frames 3. The atomized water source moistens the surface of the cement pipe from top to bottom. Although the cement pipes are stacked, there are still gaps between them. The gradually accumulated water on the top will gradually moisten the outer wall of the cement pipe downward under the action of gravity. Then the spray assembly extends into the middle of each cement pipe to spray the water source into the inner wall of the cement pipe. With the continuous movement of the support frame 3, the large-area stacked cement pipes can be wet-cured. Through this setting, not only can the large-area cement pipes be effectively collectively maintained, but the overall operation is simple, which reduces errors and failures in the maintenance process.

[0034] like Figures 1 to 6 As shown, the spray assembly includes a movable nozzle 4, two nozzles 4 are symmetrically arranged, three adjustment nozzles 16 are installed at the front end of the nozzle 4, and the adjustment nozzle 16 can adjust its own water outlet end. The nozzle 4 is also connected to the water tank 6, and the end of the nozzle 4 is also provided with a laser transmitting module and a laser receiving module;

[0035] During operation, the movable nozzle 4 is symmetrically arranged. The laser emitted by the laser emitting module will be received by the laser receiving module after passing through the middle of the cement pipe, so as to determine that the nozzle 4 has reached both ends of the cement pipe and allow the nozzle 4 to properly extend into the cement pipe. A water pump is arranged in the water tank 6 to press the water source into the nozzle 4. The adjustment nozzle 16 at the end of the nozzle 4 can change its direction. First, the adjustment nozzle 16 sprays horizontally, and then multiple adjustment nozzles 16 rotate outward to spray from the center of the cement pipe to the outside. When the adjustment nozzle 16 rotates to a vertical state, the inner wall of the cement pipe can be sprayed. During the continuous spraying process of the atomizing nozzle 14 above, the inner wall of the cement pipe is continuously searched and sprayed. The working time of the two overlaps with each other. When the cement pipe surface in one area is wetted, the inner wall of the cement pipe in this area is also completely wetted, thereby ensuring work efficiency.

[0036] like Figures 1 to 6 As shown, a plurality of telescopic nozzles 11 are installed at the bottom of the movable arm 2, and the plurality of telescopic nozzles 11 are arranged at equal distances. Sealing components are installed at both ends of the spraying sleeve 1, and the sealing components are used to seal the two ends of the spraying sleeve 1;

[0037] During operation, in order to adapt to a longer cement pipe, the two support frames 3 are driven to move to both sides by the driving wheel 7, so that the two movable arms 2 are pulled out of the spray sleeve 1. When the telescopic nozzle 11 is pulled out of the spray sleeve 1, the telescopic nozzle 11 will extend downward under the action of the internal spring. When the telescopic nozzle 11 is inside the spray sleeve 1, the bottom is blocked and cannot spray water. Only after it is moved out of the spray sleeve 1 will it spray liquid outward. The end of the movable arm 2 is open, allowing water to directly enter the spray sleeve 1, so that the atomizing nozzle 14 can receive the water source, so that the length of the equipment can be adjusted to adapt to the length of the cement pipe.

[0038] like Figures 1 to 6 As shown, the sealing assembly includes a clamping sleeve 10, which is fixedly connected to the outside of the spraying sleeve 1, and a vertically arranged sealing plate 12 is slidably clamped in the middle of the clamping sleeve 10, and an elastic pad is fixedly connected to the top of the sealing plate 12, and an electric telescopic rod 13 is fixedly connected between the upper ends of the sealing plate 12 and the clamping sleeve 10;

[0039] During operation, the sealing plate 12 is driven upward by the electric telescopic rod 13 to block the gap between the spray sleeve 1 and the movable arm 2. Only when the movable arm 2 moves outward will it contact the seal of the sealing plate 12. The setting of the elastic pad is used to increase the sealing effect.

[0040] like Figures 1 to 6 As shown, the support frame 3 is composed of two inclined support arms, a moving rail 18 is arranged between the two support arms, a moving seat 20 is slidably engaged in the moving rail 18, the moving seat 20 is connected to the nozzle 4, and moving components are arranged at both ends of the moving seat 20, a base 17 is fixedly connected to the bottom of the moving rail 18, and the base 17 is fixedly connected to the two support arms;

[0041] During operation, in order to enter cement pipes of different heights, the moving seat 20 is lifted and lowered by the moving assembly so that the moving seat 20 can be aligned with different cement pipes. The driving wheel 7 drives the entire device to move forward and backward, so that the nozzle 4 can be moved to the center of the cement pipe and the inner wall spraying and maintenance work can be carried out.

[0042] like Figures 1 to 6 As shown, the moving assembly includes a screw rod 26 and a vertical rod, the screw rod 26 is drivingly connected to one end of the moving seat 20, the vertical rod passes through the other end of the moving seat 20, the screw rod 26 and the vertical rod are both rotatably engaged with the bottom of the connecting seat 5, a driving motor for driving the screw rod 26 to rotate is installed at the bottom of the screw rod 26, the driving motor is fixedly connected to the base 17, and the moving seat 20 and the water tank 6 are connected by a hose;

[0043] During operation, the screw rod 26 is driven to rotate by the driving motor, and the lifting and lowering of the moving base 20 is controlled by forward and reverse rotation. The moving base 20 is restricted by the vertical rod and the moving rail 18 so that the moving base 20 can only move up and down.

[0044] like Figures 1 to 6 As shown, the nozzle 4 is composed of an adjustment tube 19 and a plurality of stacked tubes 15, the plurality of stacked tubes 15 are sleeved with each other, the stacked tube 15 with the largest diameter is fixedly connected to the adjustment tube 19, the adjustment nozzle 16 is installed at the end of the stacked tube 15 with the smallest diameter, a coil spring is fixedly connected between the two stacked tubes 15 that are farthest apart, the outer side of the adjustment tube 19 is rotatably connected with six dispersion tubes 22, an electric folding frame is installed between the dispersion tubes 22 and the adjustment tube 19, and a rotating component is arranged on the outer side of the adjustment tube 19;

[0045] During operation, in order to allow the nozzle 4 to partially enter the cement pipe, after the nozzle 4 and the cement pipe center are aligned, when the water in the water tank 6 is injected into the adjustment pipe 19 and the stacked pipe 15, the stacked pipe 15 will expand outwards under the action of water pressure, and then the adjustment nozzle 16 will be opened to allow water to be sprayed out from the adjustment nozzle 16. The water outlet of the adjustment nozzle 16 is small, so the water outlet speed is fast and can be sprayed a long distance. At the same time, the thrust to the stacked pipe 15 is also strong enough to stretch the coil spring. When the water pressure stops injecting, the coil spring will pull the multiple stacked pipes out of the stacked pipes. 15 is pulled to overlap, so that the end of the stacked tube 15 is away from the cement pipe, so that the nozzle 4 can move normally. At the same time, during the operation of the adjustment nozzle 16, multiple dispersion tubes 22 are unfolded under the action of the electric folding frame, so that the dispersion tubes 22 are directed to the six gaps around the cement pipe; when the cement pipes are stacked, there will be six gaps around; water is sprayed into them through the dispersion tubes 22, this process can not only quickly wet the outer wall of the cement pipes accumulated at the bottom, but also the working time overlaps with the working time of the adjustment nozzle 16, and will not affect the overall working time.

[0046] like Figures 1 to 6 As shown, the rotating assembly includes a servo motor 21, which is fixedly connected to one end of the moving seat 20 away from the water tank 6, and the output end of the servo motor 21 is fixedly connected to the outer side of the adjustment tube 19, and a flexible bellows is fixedly connected between the adjustment tube 19 and the moving seat 20;

[0047] During operation, the servo motor 21 can drive the stacked tubes 15 and the adjustment tubes 19 to rotate to a horizontal or vertical state, so that the stacked tubes 15 can fit the support frame 3 more closely, and will not occupy a large space when the equipment is stored. After each operation, the ends of the vertical stacked tubes 15 are pressed against the ground, and the stacked tubes 15 are overlapped, ensuring that the internal coil springs will not be permanently deformed due to long-term operation.

[0048] like Figures 1 to 6As shown, the adjustment nozzle 16 is ball-jointed to the end of the stacked pipe 15, and a plurality of adjustment nozzles 16 are arranged equidistantly in a ring shape, and baffles 24 are fixedly connected between adjacent adjustment nozzles 16. An adjustment component is provided on the outer side of the adjustment nozzle 16, and the adjustment component is used to change the direction of the adjustment nozzle 16. During operation, the baffle 24 is provided so that the adjustment nozzle 16 will not be damaged when the end of the stacked pipe 15 is squeezed on the ground. The direction of the adjustment nozzle 16 is changed by the adjustment component, so that the water outlet ends of the adjustment nozzle 16 are gathered together at the beginning, and then gradually spread out, so that the water source can be sprayed on the entire inner wall of the cement pipe.

[0049] like Figure 6 to Figure 7 As shown, the adjustment assembly includes a hydraulic rod 23, the outer side of the hydraulic rod 23 is fixedly connected to the inner wall of the stacked tube 15, and the top of the hydraulic rod 23 is fixedly connected to a friction rod 25, which passes through the top of the stacked tube 15 and is drivingly connected to the outer sides of the multiple stacked tubes 15;

[0050] During operation, the hydraulic rod 23 drives the friction rod 25 to move, so that the multiple adjustment nozzles 16 can be rubbed to close to the center or spread outward, and the spreading amplitude is the same, ensuring that the inner wall of the cement pipe is evenly moistened by water.

[0051] During operation, through the setting of the spray sleeve 1, the spray sleeve 1 transfers the water in the water tank 6 to the multiple atomizing nozzles 14 through the transmission pipe 8, the connecting seat 5 and the movable arm 2. The two support frames 3 raise the spray sleeve 1 upward so that the spray sleeve 1 is located above the stacked cement pipes. At the same time, it is necessary to ensure that the two ends of the cement pipes are facing the support frames 3. The atomized water source moistens the surface of the cement pipe from top to bottom. Although the cement pipes are stacked, there are still gaps between them. The gradually accumulated water on the top will gradually moisten the outer wall of the cement pipe downward under the action of gravity. Then the spray assembly extends into the middle of each cement pipe to spray the water source into the inner wall of the cement pipe. With the continuous movement of the support frame 3, the cement pipes stacked in a large area can be wet-cured. Through this setting, not only can the large area of ​​cement pipes be effectively collectively maintained, but the overall operation method is simple, which reduces the mistakes and failures in the maintenance process.

[0052] The movable nozzle 4 is symmetrically arranged. The laser emitted by the laser emitting module will be received by the laser receiving module after passing through the middle of the cement pipe, so as to determine that the nozzle 4 has reached both ends of the cement pipe and allow the nozzle 4 to properly extend into the cement pipe. A water pump is arranged in the water tank 6 to press the water source into the nozzle 4. The adjustment nozzle 16 at the end of the nozzle 4 can change its direction. First, the adjustment nozzle 16 sprays horizontally, and then multiple adjustment nozzles 16 rotate outward and spray from the center of the cement pipe to the outside. When the adjustment nozzle 16 rotates to a vertical state, the inner wall of the cement pipe can be sprayed. During the continuous spraying process of the atomizing nozzle 14 above, the inner wall of the cement pipe is continuously searched and sprayed. The working time of the two overlaps with each other. When the cement pipe surface in one area is wetted, the inner wall of the cement pipe in the area is also completely wetted, thereby ensuring work efficiency.

[0053] In order to adapt to the cement pipe with a long length, the two support frames 3 are driven to move to both sides by the driving wheel 7, so that the two movable arms 2 are pulled out from the spraying sleeve 1. When the telescopic nozzle 11 is pulled out from the spraying sleeve 1, the telescopic nozzle 11 will extend downward under the action of the internal spring. When the telescopic nozzle 11 is inside the spraying sleeve 1, the bottom is blocked and cannot spray water. Only after the spraying sleeve 1 is moved out, the liquid will be sprayed outward. The end of the movable arm 2 is open, so that water can directly enter the spraying sleeve 1, so that the atomizing nozzle 14 can receive the water source, so that the length of the equipment can be adjusted to adapt to the length of the cement pipe;

[0054] The sealing plate 12 is driven upward by the electric telescopic rod 13 to block the gap between the spray sleeve 1 and the movable arm 2. Only when the movable arm 2 moves outward will it contact the seal of the sealing plate 12. The setting of the elastic pad is used to increase the sealing effect;

[0055] In order to enter cement pipes of different heights, the moving base 20 is driven to rise and fall by the moving assembly, so that the moving base 20 can be aligned with different cement pipes, and the driving wheel 7 drives the entire device to move forward and backward, so that the nozzle 4 can be moved to the center of the cement pipe, and the inner wall spraying maintenance work can be carried out;

[0056] The screw rod 26 is driven by a driving motor to rotate, and the lifting and lowering of the moving seat 20 is controlled by forward and reverse rotation. The moving seat 20 is restricted by the vertical rod and the moving rail 18, so that the moving seat 20 can only move up and down;

[0057] In order to allow the nozzle 4 to partially enter the cement pipe, after the nozzle 4 and the cement pipe center are aligned, when the water in the water tank 6 is injected into the adjustment pipe 19 and the stacked pipe 15, the stacked pipe 15 will expand outwards under the action of water pressure, and then the adjustment nozzle 16 is opened to allow water to spray out from the adjustment nozzle 16. The water outlet of the adjustment nozzle 16 is small, so the water outlet speed is fast and can be sprayed a long distance. At the same time, the thrust to the stacked pipe 15 is also strong enough to stretch the coil spring. When the water pressure stops injecting, the coil spring will pull the multiple stacked pipes 15 out of the way. Pull the overlapped parts to keep the ends of the stacked tubes 15 away from the cement tubes, so that the nozzles 4 can move normally. Meanwhile, during the operation of the nozzle adjustment 16, the multiple dispersion tubes 22 are unfolded under the action of the electric folding frame, so that the dispersion tubes 22 face the six gaps around the cement tubes. When the cement tubes are stacked, there will be six gaps around them. Water is sprayed into the gaps through the dispersion tubes 22. This process can not only quickly wet the outer wall of the cement tubes stacked at the bottom, but also the working time overlaps with the working time of the nozzle adjustment 16, which will not affect the overall working time.

[0058] The servo motor 21 can drive the stacked pipe 15 and the adjustment pipe 19 to rotate to a horizontal or vertical state, so that the stacked pipe 15 fits the support frame 3 more closely, and does not occupy a large space when the equipment is stored. After each operation, the ends of the vertical stacked pipes 15 are pressed against the ground, so that the stacked pipes 15 overlap, ensuring that the internal spiral springs will not be permanently deformed due to long-term operation.

[0059] The baffle 24 is provided so that the adjustment nozzle 16 will not be damaged when the end of the stacked pipe 15 is pressed against the ground. The direction of the adjustment nozzle 16 is changed by adjusting the assembly so that the water outlet ends of the adjustment nozzle 16 are gathered together at the beginning and then gradually spread out, so that the water source can be sprayed on the entire inner wall of the cement pipe;

[0060] By driving the friction rod 25 to move through the hydraulic rod 23, multiple adjustment nozzles 16 can be rubbed to close to the center or spread outward, and the spreading amplitude is the same, ensuring that the inner wall of the cement pipe is evenly moistened by water.
