Description

Technical Field

[0001] This utility model relates to the field of inspection well construction and maintenance technology, specifically to an auxiliary device for the construction and maintenance of concealed inspection wells in stone paving. Background Technology

[0002] Concealed manholes in stone paving refer to a method of concealing manholes beneath the stone paving layer during the stone paving process, making them invisible from the ground surface. This method is mainly used in stone paving projects in public places such as urban roads, squares, and parks to ensure a smooth and aesthetically pleasing surface while not affecting the normal use and maintenance of the manholes. The manhole covers are made of hollow stainless steel filled with stone, with holes at the four corners for easy lifting. However, existing technologies have the following problems:

[0003] Because the top of the existing stone-paved concealed manhole covers is usually paved with the same stone as the road surface, the weight of the manhole cover is increased. When the manhole needs to be repaired, the entire manhole cover can only be lifted manually with the help of a crowbar. After the repair is completed, it must be lifted up and lowered slowly to prevent damage from bumps. This makes the overall repair process quite laborious and affects the repair efficiency. Utility Model Content

[0004] This utility model provides an auxiliary device for the construction and maintenance of concealed inspection wells in stone paving, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An auxiliary device for the construction and maintenance of concealed inspection wells in stone paving includes an auxiliary pulling mechanism. Supporting mechanisms are provided on both the left and right sides of the bottom of the auxiliary pulling mechanism. A positioning mechanism is provided between the opposing surfaces of the two supporting mechanisms. A stainless steel inspection well cover and a concealed inspection well are provided below the positioning mechanism. The stainless steel inspection well cover is snapped onto the top of the concealed inspection well. The auxiliary pulling mechanism includes a fixed plate.

A pulling and winding rope is fixedly connected to the outer wall of the connecting rod. The fixed plate has a through hole extending vertically, located below the connecting rod. The end of the pulling and winding rope away from the connecting rod passes through the through hole to the bottom of the fixed plate.

[0007] A further improvement of this utility model is that: the positioning mechanism includes a lifting square plate, the end of the pulling and winding rope away from the connecting rod is fixedly connected to the top center of the lifting square plate, and four lifting ropes are fixedly installed in a rectangular array at the bottom of the lifting square plate, with a manhole cover connecting mechanism provided at the bottom end of each of the four lifting ropes.

[0008] A further improvement of this utility model is that: the top rectangular array of the stainless steel manhole cover has four square through holes penetrating its inner cavity, the top of the stainless steel manhole cover has a paving groove penetrating its inner cavity, and the inner cavity of the paving groove is paved with a stone paving layer.

[0009] A further improvement of this utility model is that: each of the four manhole cover connecting mechanisms includes a metal rod, the four metal rods are respectively fixedly installed at the bottom of the four lifting ropes, and a horizontal plate is fixedly installed at the bottom of each of the four metal rods. The horizontal plate has the same size as the square through hole, and magnetic blocks are fixedly installed on the top left and right sides of the horizontal plate.

[0010] A further improvement of the present invention is that: both of the supporting mechanisms include a portal plate, the fixed plate is fixedly installed at the top of the horizontal position of the two portal plates, a base plate is fixedly installed at the bottom of the vertical position of the two portal plates, and two self-locking casters are fixedly installed at the bottom of the two base plates, the self-locking casters having a locking function.

[0011] A further improvement of this utility model is that a sliding rod is fixedly installed between the top of the two base plates and the bottom of the two portal plates at the horizontal position, and extension plates are fixedly installed on both the left and right sides of the lifting square plate, and the two extension plates are slidably connected to the two sliding rods respectively.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides an auxiliary device for the construction and maintenance of concealed inspection wells in stone paving.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand

[0022] Understood. The present invention will now be further described in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2As shown, this utility model provides an auxiliary device for the construction and maintenance of concealed inspection wells in stone paving, including an auxiliary pulling mechanism 1. Supporting mechanisms 2 are provided on both the left and right sides of the bottom of the auxiliary pulling mechanism 1. A positioning mechanism 3 is provided between the opposite surfaces of the two supporting mechanisms 2. A stainless steel inspection well cover 5 and a concealed inspection well 4 are provided below the positioning mechanism 3. The stainless steel inspection well cover 5 is snapped onto the top of the concealed inspection well 4. The auxiliary pulling mechanism 1 includes a fixed plate 11. A servo motor 12 is fixedly installed on the top of the fixed plate 11, and a gear reducer 13 is fixedly installed at the output end of the servo motor 12. A turntable 14 is fixedly installed at the front output end of the gear reducer 13. A connecting rod is fixedly installed at the front center of the turntable 14. A vertical plate 15 is fixedly installed on the top front side of the fixed plate 11. The front end of the connecting rod is fixedly connected to the rear side of the vertical plate 15. A pull-and-rewind rope 17 is fixedly connected to the outer wall of the connecting rod. The pull-and-rewind rope 17 is made of nylon braided support, which ensures strength and prevents breakage. The fixed plate 11 has a through hole 16 that runs vertically through the top and bottom. The through hole 16 is located below the connecting rod. The end of the pull-and-rewind rope 17 away from the connecting rod passes through the through hole 16 to the bottom of the fixed plate 11.

[0024] By activating the servo motor 12 on the top of the fixed plate 11, the speed can be reduced and the torque increased by the gear reducer 13, thereby driving the turntable 14 and the connecting rod to rotate on the rear side of the upright plate 15, and winding up the pull-up rope 17. Thus, by connecting the pull-up rope 17 with the lifting square plate 31, the lifting square plate 31 is lifted as a whole, and finally the stainless steel inspection well cover 5 is lifted up.

[0025] like Figure 3 , Figure 4 As shown, the positioning mechanism 3 includes a lifting square plate 31. The end of the winding rope 17 furthest from the connecting rod is fixedly connected to the top center of the lifting square plate 31. Four lifting ropes 32 are fixedly installed in a rectangular array at the bottom of the lifting square plate 31. The lifting ropes 32 are made of nylon braided support, ensuring strength and preventing breakage. Each of the four lifting ropes 32 has a manhole cover connecting mechanism 33 at its bottom. Depending on the size of the stainless steel manhole cover 5, the manhole cover connecting mechanism 33 can freely change position with the help of the lifting ropes, easily adapting to different sizes of manhole covers. The top rectangular array has four square through holes 51 that penetrate its inner cavity. The top of the stainless steel inspection manhole cover 5 has a paving groove that penetrates its inner cavity. The inner cavity of the paving groove is paved with a stone paving layer 52. The four manhole cover connecting mechanisms 33 each include a metal rod 331. The four metal rods 331 are respectively fixedly installed at the bottom of the four lifting ropes 32. The bottom of the four metal rods 331 is fixedly installed with a horizontal plate 332. The horizontal plate 332 is the same size as the square through hole 51. Magnetic blocks 333 are fixedly installed on the top left and right sides of the horizontal plate 332.

[0026] When it is necessary to open the stainless steel inspection well cover 5 to inspect the concealed inspection well 4, the metal rods 331 at the bottom of the four lifting ropes 32 at the bottom of the lifting square plate 31 can be inserted into the four square through holes 51 at the top of the stainless steel inspection well cover 5 by means of the horizontal plate 332, and rotated 90 degrees to complete the limit. The magnetic block 333 at the top of the horizontal plate 332 can be used to attract the inner wall of the stainless steel inspection well cover 5 to prevent the horizontal plate 332 from turning open by itself.

[0027] like Figure 5 As shown, both support mechanisms 2 include a portal plate 21. A fixed plate 11 is fixedly installed on the top of the horizontal position of the two portal plates 21. A base plate 22 is fixedly installed on the bottom of the vertical position of the two portal plates 21. Two self-locking casters 24 are fixedly installed on the bottom of the two base plates 22. The self-locking casters 24 have a locking function. A sliding rod 23 is fixedly installed between the top of the two base plates 22 and the bottom of the horizontal position of the two portal plates 21. Extension plates 311 are fixedly installed on the left and right sides of the lifting square plate 31. The two extension plates 311 are slidably connected to the two sliding rods 23 respectively.

[0028] When the lifting square plate 31 is raised, the sliding connection between its left and right side extension plates 311 and the slide rod 23 can maintain the stability of the lifting square plate 31. After the stainless steel inspection well cover 5 is lifted, the two self-locking universal wheels 24 at the bottom of the two base plates 22 can be released from the locked state, so that the overall auxiliary device can be pushed open and the stainless steel inspection well cover 5 can be moved horizontally, which facilitates the maintenance work inside the concealed inspection well 4.

[0029] The working principle of the auxiliary device for construction and maintenance of concealed inspection wells in stone paving will be explained in detail below.

[0030] like Figure 1-5As shown, when it is necessary to open the stainless steel inspection well cover 5 to inspect the concealed inspection well 4, the metal lifting rods 331 at the bottom of the four lifting ropes 32 at the bottom of the lifting square plate 31 can be inserted into the four square through holes 51 opened at the top of the stainless steel inspection well cover 5 by means of the horizontal plate 332, and rotated 90 degrees to complete the limit. The magnetic block 333 at the top of the horizontal plate 332 and the adsorption between the horizontal plate 332 and the inner wall of the stainless steel inspection well cover 5 can prevent the horizontal plate 332 from turning open by itself. Then, it is only necessary to start the servo motor 12 at the top of the fixed plate 11, which can reduce the speed and increase the torque by means of the gear reducer 13, thereby driving the turntable 14 and the connecting rod. Rotating the rear side of the upright plate 15 winds up the pull rope 17, thereby using the connection between the pull rope 17 and the lifting plate 31 to lift the lifting plate 31 as a whole, and finally lift the stainless steel inspection well cover 5. During the rise, the sliding connection between the extension plates 311 on the left and right sides of the lifting plate 31 and the slide rod 23 can maintain the stability of the lifting plate 31. After the stainless steel inspection well cover 5 is lifted, the two self-locking universal wheels 24 at the bottom of the two base plates 22 can be released, thereby pushing the entire auxiliary device open and moving the stainless steel inspection well cover 5 horizontally, which facilitates the maintenance work inside the concealed inspection well 4.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
