Technical Field

[0001] The present invention relates to the technical field of pipe well construction, and particularly relates to a municipal pipe well construction auxiliary device and a using method thereof. Background Art

[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 led to an increasing number and types of pipe wells set in municipal engineering, including water pipe wells, sewage wells, power maintenance 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 drawbacks still exist in the process of lifting the manhole cover in the prior art: 1. In the prior art, when lifting the manhole cover, multiple workers are required to lift the manhole cover by fitting the barb blocks 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 cannot be applied to large-scale pipe well construction; 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.

[0004] 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

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

[0026] 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.

[0027] ReferenceFigure 8 In order to increase the stability of the hydraulic cylinder 27, a mounting seat 28 is welded on the top of the bottom plate 1. The hydraulic cylinder 27 is fixed through the mounting seat 28. The mounting seat 28 can limit and fix the hydraulic cylinder 27 to prevent the hydraulic cylinder 27 from shaking during operation.

[0028] Reference Figure 1 and Figure 2 Universal wheels to be braked are fixedly mounted at the four corners of the bottom of the base plate 1. These universal wheels make the base plate 1 easy to move on the ground, and the brake function ensures that the base plate 1 can be fixed to prevent it from sliding when needed.

[0029] Example 2: Reference Figure 9 , improved on the basis of Example 1: inside the bottom plate 1, a placement cavity 49 is provided. In 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 tube 47 is slidably connected in the notch 55. A pipe 51 is fixedly connected to one side of the movable tube 47, and one end of the pipe 51 extends into the placement cavity 49 and is connected to the air outlet end of the blower 50. In this way, when the blower 50 is working, the generated wind can enter the movable tube 47 through the pipe 51. At the bottom of the movable tube 47, a plurality of exhaust holes 48 are fixed. When the blower 50 blows air into the movable tube 47, the wind will be discharged from the exhaust holes 48, thereby realizing the function of blowing air downward.

[0030] In actual use, first, the blower 50 can be started, and the wind generated by the blower 50 is guided into the moving tube 47 through the pipe 51 and blown downward through the exhaust hole 48. At this time, the moving tube 47 can be pulled to slide in the notch 55 through the multiple handles 53 on the top of the moving tube 47, so that the exhaust hole 48 is aligned with the manhole cover. Since the wind is blown downward from the exhaust hole 48, the dust on the manhole cover can be effectively removed.

[0031] After the manhole cover is taken out, the movable tube 47 can be pulled by the handle 53 to move the movable tube 47 to the top of the pipe well. At this time, the blower 50 is still working, blowing air into the pipe well through the exhaust hole 48. In this way, not only the inside of the pipe well can be ventilated to remove the harmful gas that may exist inside the pipe well, but also oxygen can be supplemented, so that the staff can have a relatively safe and comfortable environment when they go down the well for maintenance later.

[0032] In addition, in order to facilitate the fixing of the moving tube 47, a fourth magnet 52 is fixedly embedded on the inner wall of one side of the notch 55, and an iron block is fixedly embedded on one side of the moving tube 47. When the moving tube 47 moves to a desired position, the iron block generates a magnetic attraction with the fourth magnet 52, thereby adsorbing and fixing the moving tube 47 in the notch 55 to prevent it from moving.

[0033] A method for using an auxiliary device for municipal pipe well construction, comprising the following steps: 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 plate 43. The third magnet 39 generates a magnetic suction force on the rotating rod 38 to release the braking of 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, 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; 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. The ultrasonic detector 22 is used to perform ultrasonic detection on the manhole cover on the placement plate 10; 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. The moving pipe 47 is driven to move by the handle 53, so as to be able to remove the dust on the manhole cover. After the manhole cover is removed, the moving pipe 47 is moved above the pipe well, and air is blown into the pipe well through the exhaust holes 48 for ventilation of the inside of the pipe well, removing the harmful gases inside the pipe well and supplementing oxygen, which is convenient for the later staff to go down the well for maintenance; S4. When the staff needs to go down 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 plate 43. The hexagonal block 40 is inserted into the hexagonal groove 41. Then, buckle the safety harness worn on the staff with the buckle 8. Then, drive the motor 46 to drive the second winding roller 5 to rotate, and lift the staff into the pipe well to facilitate the lifting of the staff; 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 disk 10 and the manhole cover thereon to rotate. Additionally, 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.
