[0002] Municipal public facilities involve the maintenance, emergency rescue, emergency handling and management of municipal facilities such as urban sewage discharge, rainwater discharge, street lights, roads, bridges, tunnels, squares, culverts, air defense, etc. With the development of urban infrastructure construction, the developed underground pipe networks have made the number and types of pipe wells set in municipal engineering more and more, including water pipe wells, sewage wells, power inspection wells, etc.

[0003] In the prior art, when carrying out pipe well construction, it is necessary to lift the manhole cover before construction operations can be carried out. The following disadvantages still exist in the process of lifting the manhole cover in the prior art:

[0004] 1. In the prior art, when lifting the manhole cover, it is necessary for multiple workers to lift the manhole cover by fitting the barbs with the lifting holes on the pipe well. Moreover, the manhole cover is heavy, so it is time-consuming and laborious to lift manually and is not applicable to large-scale pipe well construction;

[0005] 2. During pipe well construction, problems such as cracks, rust, and deformation in the pipe well cannot be detected, resulting in potential hazards to the road after the manhole cover is reused later.

[0006] In view of the above problems, the present invention document proposes a municipal pipe well construction auxiliary device and a using method thereof. Summary of the Invention

[0007] The purpose of the present invention is to solve the disadvantages of the existing manual lifting being time-consuming and laborious, not being applicable to large-scale pipe well construction, and being unable to detect problems such as cracks, rust, and deformation in the pipe well, and to propose a municipal pipe well construction auxiliary device and a using method thereof.

The rotating arm rotates out of the storage groove and is in a horizontal state, and the ultrasonic detector is used to perform ultrasonic detection on the manhole cover on the placement plate.

[0016] In a possible design, the driving structure includes a cavity provided in the bottom plate. The bottom end of the rotating shaft extends rotatably into the cavity. A second synchronous pulley is fixedly sleeved on the outer wall of the rotating shaft and is located in the cavity. One inner wall of the notch is rotatably connected to a first synchronous pulley through a base. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.

When the second winding roller rotates, the rotating cylinder can be driven to rotate through the cooperation of the first bevel gear and the second bevel gear; the second winding roller drives the rotating rod and the rotating cylinder to rotate through the cooperation of the first bevel gear and the second bevel gear. The rotating rod drives the rotating shaft to rotate through the cooperation of the hexagonal block, the hexagonal groove, and the first synchronous pulley and the second synchronous pulley, thereby driving the placement plate and the manhole cover thereon to rotate. The ultrasonic detector can detect the positions of the manhole cover on the placement plate at different angles.

[0017] In a possible design, the reciprocating structure includes a hydraulic cylinder fixed to the top of the bottom plate.

A first magnet is fixedly embedded on the side of the sliding seat away from the ultrasonic detector, and a magnetic attraction force is generated between the first magnet and the second magnet to drive the sliding seat to reciprocate; when the placement plate rotates, the cooperation of the pin column and the track groove drives the second piston plate and the push rod to reciprocate.

Therefore, the ultrasonic detector can comprehensively detect the manhole cover.

[0018] In a possible design, a strip-shaped hole is provided on one side of the rotating cylinder. A dial plate is slidably connected in the strip-shaped hole, and one end of the dial plate extends into the rotating cylinder and is fixedly connected to the rotating rod for driving the rotating rod to lift. A third magnet is fixed to the inner wall of the top of the rotating cylinder, and an iron block is fixedly embedded at the top end of the rotating rod. The cooperation between the third magnet and the iron block is used to adsorb the rotating rod into the rotating cylinder. When the first winding roller is rotated above the notch, the rotating rod is adsorbed into the rotating cylinder by the third magnet to avoid interference between the rotating rod and the bottom plate when the rotating column and the top plate rotate later.

[0019] In a possible design, a mounting seat is welded to the top of the bottom plate, and the hydraulic cylinder fixedly penetrates through the mounting seat to increase the stability of the hydraulic cylinder.

A plurality of exhaust holes are fixed to the bottom of the moving pipe for blowing air downward. The cooperation between the blower and the pipe blows air into the moving pipe, blows air onto the manhole cover through the exhaust holes, drives the moving pipe to move through the handle, and thus can remove the dust on the manhole cover. When the manhole cover is taken out, the moving pipe is moved above the pipe well, and air is blown into the pipe well through the exhaust holes for ventilating the inside of the pipe well, exhausting the harmful gases inside the pipe well and supplementing oxygen, which is convenient for the later staff to go down the well for maintenance.

[0022] In a possible design, a plurality of handles are fixed to the top of the moving pipe for pulling the moving pipe to move. A fourth magnet is fixedly embedded in one side inner wall of the notch.

[0023] In this application, a usage method of a municipal pipe well construction auxiliary device includes the following steps:

[0024] S1. Move the bottom plate above the manhole cover, the dial plate pushes the rotating rod to move upward, and the magnet releases the brake. The motor drives the rotating column and the top plate to rotate, and moves the first winding roller and the electromagnet above the manhole cover. The first winding roller releases the pulling rope. After the electromagnet is energized to adsorb the manhole cover, the first winding roller rotates reversely to lift the manhole cover, and then rotates the top plate reversely to place the manhole cover on the placement plate.

[0025] S2. The electromagnet moves upward to drive the lifting plate and the rack. Through the transmission of the rack and the spur gear, the rotating arm rotates out to the horizontal, and the ultrasonic detector detects the manhole cover.

[0026] S3. When the bottom plate moves, the blower blows air into the moving pipe through the pipeline, clears the dust on the manhole cover and blows it into the pipe well for ventilation.

[0027] S4. When it is necessary to carry out maintenance work in the well, operate the dial plate to move the rotating rod and the hexagonal block downward and lock them with the first synchronous pulley, connect the safety harness of the staff with the buckle; the motor drives the second winding roller to rotate, and the staff is lowered into the pipe well.

[0031] In the present invention, a second piston plate is hermetically and slidably connected in the hydraulic cylinder. A pin is fixed at the bottom of the push rod. A turntable is fixedly sleeved on the outer wall of the rotating shaft. A track groove slidably matched with the pin is provided at the top of the turntable.

[0050] Reference Figure 2 and Figure 4 In order to avoid interference between the rotating rod 38 and the bottom plate 1 when the rotating column 2 and the top plate 3 rotate in the later stage, a strip hole 42 is provided on one side of the rotating cylinder 37, and a paddle plate 43 is slidably connected in the strip hole 42, and one end of the paddle plate 43 extends into the rotating cylinder 37 and is welded to the rotating rod 38, and the rotating rod 38 can be driven to rise and fall by paddle plate 43, and a third magnet 39 is bonded to the inner wall of the top of the rotating cylinder 37 by strong glue, and an iron block is fixedly embedded on the top of the rotating rod 38, and the cooperation between the third magnet 39 and the iron block can absorb the rotating rod 38 into the rotating cylinder 37, and when the first winding roller 4 is rotated to above the notch 55, the rotating rod 38 can be absorbed into the rotating cylinder 37 by the third magnet 39, so as to avoid interference between the rotating rod 38 and the bottom plate 1 when the rotating column 2 and the top plate 3 rotate in the later stage.

[0051] ReferenceFigure 8 To increase the stability of the hydraulic cylinder 27, a mounting seat 28 is welded to the top of the bottom plate 1. The hydraulic cylinder 27 is fixedly penetrated through the mounting seat 28, and the mounting seat 28 can play a role in limiting and fixing the hydraulic cylinder 27 to prevent the hydraulic cylinder 27 from shaking during operation.

[0052] Refer to Figure 1 and Figure 2 At the four corners of the bottom of the bottom plate 1, universal wheels to be braked are fixedly installed. These universal wheels enable the bottom plate 1 to move conveniently on the ground, and the braking function ensures that the bottom plate 1 can be fixed to prevent it from sliding when needed.

[0053] Embodiment 2: Refer to Figure 9 On the basis of Embodiment 1, an improvement is made: inside the bottom plate 1, a placement cavity 49 is provided. Inside the placement cavity 49, a blower 50 is fixedly installed. At a certain position of the bottom plate 1, a notch 55 is provided, and a movable pipe 47 is slidably connected inside this notch 55. One side of the movable pipe 47 is fixedly connected to a pipe 51, and one end of the pipe 51 extends into the placement cavity 49 and is communicated with the air outlet end of the blower 50. In this way, when the blower 50 operates, the generated air can enter the movable pipe 47 through the pipe 51. At the bottom of the movable pipe 47, a plurality of exhaust holes 48 are fixed. When the blower 50 blows air into the movable pipe 47, the air will be discharged from the exhaust holes 48 to achieve the function of blowing air downward.

[0054] During actual use, first, the blower 50 can be started. The air generated by the blower 50 is guided into the movable pipe 47 through the pipe 51 and blown downward through the exhaust holes 48. At this time, the movable pipe 47 can be pulled to slide in the notch 55 through a plurality of handles 53 at the top of the movable pipe 47, so that the exhaust holes 48 are aligned with the manhole cover. Since the air is blown downward from the exhaust holes 48, the dust on the manhole cover can be effectively removed.

[0055] After the manhole cover is removed, the movable pipe 47 can continue to be pulled through the handle 53 to move the movable pipe 47 above the pipe well. At this time, the blower 50 is still operating and blowing air into the pipe well through the exhaust holes 48. In this way, not only can the inside of the pipe well be ventilated, harmful gases that may exist inside the pipe well be removed, but also oxygen can be supplemented, enabling a relatively safe and comfortable environment for later maintenance workers to enter the well.

[0056] In addition, to facilitate the fixation of the movable pipe 47, a fourth magnet 52 is fixedly embedded on one inner wall of the notch 55, and an iron block is fixedly embedded on one side of the movable pipe 47. When the movable pipe 47 moves to the required position, the iron block will generate magnetic attraction with the fourth magnet 52, thereby adsorbing and fixing the movable pipe 47 in the notch 55 to prevent it from moving.

[0057] A method for using an auxiliary device for municipal pipe well construction, comprising the following steps:

[0058] S1. Push the bottom plate 1 to move until the notch 55 is located above the manhole cover. Push the rotating rod 38 upward through the dial 43. The third magnet 39 generates a magnetic suction force on the rotating rod 38 to release the braking between the hexagonal block 40 and the first synchronous pulley 35. At this time, the hexagonal block 40 is located above the mounting seat 28. Then, drive the rotating column 2 to rotate through the motor. The rotating column 2 drives the top plate 3 to rotate, and move the first winding roller 4 and the electromagnet 7 to above the notch 55. The motor drives the first winding roller 4 to rotate to release the winding of the pulling rope 6. Place the electromagnet 7 above the manhole cover. The electromagnet 7 is energized to generate a magnetic suction force on the manhole cover. Then, the first winding roller 4 rotates in the reverse direction to pull the manhole cover upward. After that, the rotating column 2 and the top plate 3 rotate in the reverse direction and place the manhole cover on the placement plate 10 to initially complete the removal of the manhole cover;

[0059] S2. After the manhole cover is placed on the placement plate 10, the electromagnet 7 moves upward and pushes the lifting plate 11 upward to compress the spring 13. The lifting plate 11 drives the rack 14 to move upward. The cooperation between the rack 14 and the spur gear 18 drives the fixed shaft 17 and the rotating arm 19 to rotate. The rotating arm 19 rotates out of the storage groove 16 and is in a horizontal state. Use the ultrasonic detector 22 to perform ultrasonic detection on the manhole cover on the placement plate 10;

[0060] S3. In addition, when the bottom plate 1 moves above the manhole cover, air is blown into the moving pipe 47 through the cooperation of the blower 50 and the pipe 51, and air is blown onto the manhole cover through the exhaust holes 48. Drive the moving pipe 47 to move through the handle 53, so as to be able to remove the dust on the manhole cover. After the manhole cover is removed, move the moving pipe 47 above the pipe well and blow air into the pipe well through the exhaust holes 48 for ventilation of the inside of the pipe well, exhausting the harmful gases inside the pipe well and supplementing oxygen, which is convenient for the later staff to enter the well for maintenance;

[0061] S4. When the staff needs to enter the well for maintenance, the second winding roller 5 is located above the pipe well. Push the rotating rod 38 and the hexagonal block 40 downward through the dial 43. The hexagonal block 40 is inserted into the hexagonal groove 41. Then, buckle the safety harness worn by the staff with the buckle 8. Then, drive the motor 46 to drive the second winding roller 5 to rotate to lift the staff into the pipe well, which is convenient for the staff to lift and lower;

[0062] S5. In addition, the second volume take-up roller 5 drives the rotating rod 38 and the rotating cylinder 37 to rotate through the cooperation of the first bevel gear 44 and the second bevel gear 45. The rotating rod 38 drives the rotating shaft 9 to rotate through the cooperation of the hexagonal block 40, the hexagonal groove 41, and the first synchronous wheel 35 and the second synchronous wheel 36, thereby driving the placement plate 10 and the manhole cover thereon to rotate. In addition, the cooperation of the pin column 31 and the track groove 33 drives the second piston plate 29 and the push rod 34 to reciprocate. The hydraulic oil in the hydraulic cylinder 27 and the hydraulic groove 24 drives the first piston plate 25 to move synchronously. The first piston plate 25 drives the ultrasonic detector 22 and the sliding seat 21 to reciprocate through the magnetic attraction between the second magnet 26 and the first magnet 23. Therefore, the ultrasonic detector 22 can comprehensively detect the manhole cover.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 46, the ultrasonic detector 22, and the electromagnet 7 are common knowledge. They all belong to conventional means or well-known common sense and will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
