Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a multi-functional integrated municipal well cover lifting device. Background Art

[0002] A well cover is used to cover deep wells or municipal pipe networks in the road to prevent people or objects from falling. It can be divided into metal well covers, high-strength fiber cement concrete well covers, resin well covers, etc. Generally, it is circular. When workers need to enter the municipal pipe network for operation, the well cover needs to be opened. It can be used in municipal pipe networks, green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] At present, workers usually use an iron hook to hook the lifting hole of the well cover, and then manually lift it upward to open the well cover. However, some well covers are made of concrete or metal and are relatively heavy, making it inconvenient for workers to lift manually. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a multi-functional integrated municipal well cover lifting device.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions: A multi-functional integrated municipal well cover lifting device, including a frame, an installation rod is arranged on the frame, a rotating tube arranged concentrically is rotatably arranged on the installation rod, a driving component for driving the rotating tube to rotate is arranged on the installation rod, two concentrically arranged wire winding rollers are arranged at intervals on the rotating tube, a rope is wound on the wire winding roller, one end of the rope is connected to the wire winding roller and the other end is connected to a fixing component, the fixing component includes a square tube with an opening facing downward, two mounting plates are arranged at intervals at the lower end of the square tube, two clamping plates are rotatably arranged between the lower parts of the two mounting plates, a starting unit for controlling the clamping plates is arranged in the square tube, and a limiting unit is also arranged between the lower parts of the two mounting plates.

[0006] By adopting the above technical solutions, the frame, installation rod, driving component, wire winding roller, square tube, clamping plate, starting unit, and limiting unit are provided. When it is necessary to open the well cover, the driving component is used to drive the rotating tube to rotate, driving the wire winding roller to rotate, so that one end of the rope connected to the fixing component gradually descends. Subsequently, the clamping plate parts of the two fixing components are respectively passed through the lifting holes of the well cover, and then the clamping plates are driven to rotate by the starting unit. The limiting unit limits the maximum position of the rotation of the clamping plate to be perpendicular to the length direction of the square tube in the length direction of the clamping plate. The driving unit then drives the wire winding roller to rotate, driving one end of the rope connected to the fixing component to gradually rise. The clamping plate contacts the bottom surface of the well cover, so that the rising of the rope drives the well cover to rise, eliminating the need for manual lifting and reducing the labor intensity of workers.

[0007] Further, two fixed shafts arranged at intervals are provided between the lower parts of the two mounting plates. One side of the clamping plate is rotatably arranged on the corresponding fixed shaft. A torsion spring is sleeved on the fixed shaft. One end of the torsion spring is connected to the fixed shaft, and the other end is connected to the clamping plate.

[0008] By adopting the above technical solution, the fixed shaft and the torsion spring are provided. The torsion spring provides the force for the clamping plate to rotate, ensuring that the clamping plate is in a retracted state when not opened, which is convenient for the clamping plate to pass through the lifting hole of the manhole cover.

[0009] Further, the starting unit includes a mounting block arranged at the lower part inside the square tube. A sliding hole is formed in the mounting block along the length direction of the square tube. A sliding rod is slidably arranged in the sliding hole. A blocking piece is arranged at the upper end of the sliding rod, and a pushing block is arranged at the lower end. A compression spring is sleeved on the rod body of the sliding rod between the blocking piece and the mounting block. One end of the compression spring is connected to the blocking piece, and the other end is connected to the mounting block. A square hole is formed in the bottom of the square tube, and a square rod is slidably arranged in the square hole. The square rod is connected to the blocking piece.

[0010] By adopting the above technical solution, the mounting block, the sliding hole, the blocking piece, the sliding rod, the pushing block, and the compression spring are provided. After the clamping plate is located below the manhole cover, the square rod is pressed, driving the blocking piece, the sliding rod, and the pushing block to move. The pushing block contacts the clamping plate and pushes the clamping plate to rotate slightly. Then, the rope pulls the square tube to rise. The upper part of the clamping plate contacts the bottom surface of the manhole cover. The square tube continues to rise, driving the mounting plate to rise, so that the upper part of the clamping plate slides on the bottom surface of the manhole cover and rotates around the fixed shaft as a whole, making the clamping plate fully open and contact the bottom surface of the manhole cover. During the movement of the blocking piece, the sliding rod, and the pushing block, the compression spring is compressed. When the square rod is released, the compression spring loses its restriction and pushes the baffle, the sliding rod, and the pushing block to reset.

[0011] Further, first chamfers are provided at both edges of the pushing block close to the two clamping plates, and a second chamfer is provided at the edge of the clamping plate close to the pushing block.

[0012] By adopting the above technical solution, the first chamfer and the second chamfer are provided, so that the contact surface between the pushing block and the clamping plate is an inclined surface, which is convenient for the pushing block to push open the clamping plate.

[0013] Further, the limiting unit includes a limiting plate arranged between the bottoms of the two mounting plates, and a limiting block is arranged on one side of the bottom of the clamping plate away from the limiting plate.

[0014] By adopting the above technical solution, the limiting plate and the limiting block are provided. When the length direction of the clamping plate after rotation is perpendicular to the length direction of the square tube, the limiting block contacts the plate surface of the limiting plate, making the clamping plate unable to rotate further.

[0015] Further, the driving assembly includes a driven wheel coaxially arranged on one side of the rotating tube. An installation seat is arranged on the installation rod, a driving motor is horizontally arranged on the installation seat, a driving wheel is arranged on the output shaft of the driving motor, and the driving wheel meshes with the driven wheel.

[0016] By adopting the above technical solution, the driven wheel, the installation seat, the driving motor, and the driving wheel are provided. The driving motor drives the driving wheel to rotate, thereby driving the driven wheel and the rotating tube to rotate, and further driving the wire winding roller to rotate.

[0017] Further, a plurality of convex strips are circumferentially and spacedly arranged on the outer wall of the rotating tube. The length direction of the convex strips is consistent with the length direction of the rotating tube. Grooves are formed on the wire winding roller corresponding to the convex strips, and the grooves are slidably connected with the convex strips.

[0018] By adopting the above technical solution, the convex strips and the grooves are provided, so that the wire winding roller can slide along the length direction of the convex strips, thereby enabling the position of the wire winding roller to be adjusted according to the position of the lifting hole of the manhole cover.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In this application, the frame, the installation rod, the driving assembly, the wire winding roller, the square tube, the clamping plate, the starting unit, and the limiting unit are provided. When it is necessary to open the manhole cover, the driving assembly drives the rotating tube to rotate, driving the wire winding roller to rotate, so that one end of the rope connecting the fixing assembly gradually descends. Subsequently, the clamping plate parts of the two fixing assemblies are respectively passed through the lifting holes of the manhole cover, and then the starting unit drives the clamping plate to rotate. The limiting unit limits the maximum rotation position of the clamping plate to be perpendicular to the length direction of the square tube. The driving unit then drives the wire winding roller to rotate, driving one end of the rope connecting the fixing assembly to gradually rise. The clamping plate contacts the bottom surface of the manhole cover, so that the rising rope drives the manhole cover to rise, eliminating the need for manual lifting and reducing the labor intensity of the staff.

[0021] 2. In this application, the installation block, the sliding hole, the retaining piece, the sliding rod, the pushing block, and the compression spring are provided. After the clamping plate is located below the manhole cover, press the square rod, driving the retaining piece, the sliding rod, and the pushing block to move. The pushing block contacts the clamping plate and pushes the clamping plate to rotate slightly. Subsequently, the rope pulls the square tube to rise. The upper part of the clamping plate contacts the bottom surface of the manhole cover. The continuous rising of the square tube drives the mounting plate to rise, causing the upper part of the clamping plate to slide on the bottom surface of the manhole cover and rotate integrally around the fixed shaft, so that the clamping plate is completely opened and contacts the bottom surface of the manhole cover. During the movement of the retaining piece, the sliding rod, and the pushing block, the compression spring is compressed. When the square rod is released, the compression spring loses its restraint and pushes the baffle, the sliding rod, and the pushing block to reset. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0028] As Figures 1-4 shown, the embodiment of the present application discloses a multi-functional integrated municipal manhole cover lifting device, including a frame 10, a mounting rod 11, a rotating tube 20, a driving assembly 30, and a fixing assembly 40. The mounting rod 11 is horizontally arranged on the frame 10. The rotating tube 20 is rotatably arranged on the mounting rod 11 and is concentrically arranged with the mounting rod 11. The driving assembly 30 is arranged on the mounting rod 11 and is used to drive the rotating tube 20 to rotate. Two concentrically arranged wire reels 21 are spaced on the rotating tube 20. A rope 22 is wound around the wire reel 21. One end of the rope 22 is connected to the wire reel 21, and the other end is connected to the fixing assembly 40. The fixing assembly 40 is used to connect to the manhole cover. The driving assembly 30 drives the rotating tube 20 to rotate, driving the wire reel 21 to rotate, winding or loosening the rope 22, thereby changing the height of the fixing assembly 40.

[0029] Specifically, the driving assembly 30 includes a driven wheel 31 concentrically arranged on one side of the rotating tube 20. An installation seat 32 is arranged on the installation rod 11. A driving motor 33 is horizontally arranged on the installation seat 32. A driving wheel 34 is arranged on the output shaft of the driving motor 33. The driving wheel 34 meshes with the driven wheel 31. The driving motor 33 drives the driving wheel 34 to rotate, thereby driving the driven wheel 31 and the rotating tube 20 to rotate, and further driving the wire winding roller 21 to rotate. A plurality of convex strips 23 are circumferentially and spacedly arranged on the outer wall of the rotating tube 20. The length direction of the convex strips 23 is consistent with the length direction of the rotating tube 20. Grooves 24 corresponding to the convex strips 23 are formed on the wire winding roller 21. The grooves 24 are slidably connected with the convex strips 23, so that the position of the wire winding roller 21 can be adjusted according to the position of the hoisting hole of the manhole cover.

[0030] The fixing assembly 40 includes a square tube 41 with an opening facing downward. The bottom of the square tube 41 is connected to the rope 22. Two mounting plates 42 are spacedly arranged at the lower end of the square tube 41. The mounting plates 42 are located on both sides of the opening of the square tube 41. Two clamping plates 43 are rotatably arranged between the lower parts of the two mounting plates 42. Specifically, when setting, two fixing shafts 44 arranged at intervals are arranged between the lower parts of the two mounting plates 42. One side of the clamping plate 43 is rotatably arranged on the corresponding fixing shaft 44. A torsion spring is sleeved on the fixing shaft 44. One end of the torsion spring is connected to the fixing shaft 44 and the other end is connected to the clamping plate 43, ensuring that the clamping plate 43 is in a closed state when not opened, which is convenient for the clamping plate 43 to pass through the hoisting hole of the manhole cover.

[0031] When setting, a starting unit 50 for controlling the clamping plate 43 is arranged in the square tube 41. The starting unit 50 includes a mounting block 51 arranged at the lower part inside the square tube 41. A sliding hole is formed in the mounting block 51 along the length direction of the square tube 41. A sliding rod 52 is slidably arranged in the sliding hole. A blocking piece 53 is arranged at the upper end of the sliding rod 52 and a pushing block 54 is arranged at the lower end. A square hole is formed in the bottom of the square tube 41. A square rod 56 is slidably arranged in the square hole. The square rod 56 is connected to the blocking piece 53, so that the sliding rod 52, the blocking piece 53, the pushing block 54 and the square rod 56 move synchronously. A compression spring 55 is sleeved on the rod body of the sliding rod 52 between the blocking piece 53 and the mounting block 51. One end of the compression spring 55 is connected to the blocking piece 53 and the other end is connected to the mounting block 51. Press the square rod 56 to drive the blocking piece 53, the sliding rod 52 and the pushing block 54 to move. The pushing block 54 contacts the clamping plate 43 and pushes the clamping plate 43 to rotate slightly. Subsequently, the rope 22 pulls the square tube 41 to rise. The upper part of the clamping plate 43 contacts the bottom surface of the manhole cover. The square tube 41 continues to rise and drives the mounting plate 42 to rise, so that the upper part of the clamping plate 43 slides on the bottom surface of the manhole cover and rotates integrally around the fixing shaft 44, so that the clamping plate 43 is completely opened and contacts the bottom surface of the manhole cover; during the movement of the blocking piece 53, the sliding rod 52 and the pushing block 54, the compression spring 55 is compressed. When the square rod 56 is released, the compression spring 55 loses its restriction and pushes the baffle, the sliding rod 52 and the pushing block 54 to reset.

[0032] When the manhole cover needs to be placed back on the wellhead, the driving motor 33 drives the wire winding roller 21 to rotate, releases the rope 22, so that the fixing assembly 40 and the manhole cover gradually descend. After the manhole cover covers the wellhead, the driving motor 33 drives the wire winding roller 21 to continue rotating, so that the square tube 41 and the clamping plate 43 continue to descend. Under the action of the torsion spring, the clamping plate 43 resets. Subsequently, the driving motor 33 drives the wire winding roller 21 to rotate, retrieves the rope 22, and drives the fixing assembly 40 to rise through the lifting hole of the manhole cover. First chamfers 57 are provided at both edges of the pushing block 54 adjacent to the two clamping plates 43, and a second chamfer 45 is provided at the edge of the clamping plate 43 adjacent to the pushing block 54, so that the contact surface between the pushing block 54 and the clamping plate 43 is an inclined surface, facilitating the pushing block 54 to push open the clamping plate 43.

[0033] Specifically, a limiting unit 60 is further provided between the lower parts of the two mounting plates 42. The limiting unit 60 limits the maximum position of the rotation of the clamping plate 43 to be that the length direction of the clamping plate 43 is perpendicular to the length direction of the square tube 41. The limiting unit 60 includes a limiting plate 61 provided between the bottoms of the two mounting plates 42. A limiting block 62 is provided on the side of the bottom of the clamping plate 43 away from the limiting plate 61. When the clamping plate 43 rotates to a position where its length direction is perpendicular to the length direction of the square tube 41, the limiting block 62 contacts the plate surface of the limiting plate 61, making the clamping plate 43 unable to rotate further. The driving assembly 30 drives the rotating tube 20 to rotate, drives the wire winding roller 21 to rotate, so that one end of the rope 22 connecting the fixing assembly 40 gradually descends. Subsequently, the clamping plate 43 parts of the two fixing assemblies 40 are respectively passed through the lifting holes of the manhole cover, and then the starting unit 50 is used to drive the clamping plate 43 to rotate until the length direction of the clamping plate 43 is perpendicular to the length direction of the square tube 41, and the plate surface of the clamping plate 43 contacts the bottom surface of the manhole cover. The driving unit then drives the wire winding roller 21 to rotate, drives one end of the rope 22 connecting the fixing assembly 40 to gradually rise, so that the rising of the rope 22 drives the manhole cover to rise.

[0034] Rollers are provided at the bottom of the frame 10. After the manhole cover is lifted and risen, the frame 10 is pushed to move, thereby moving the position of the manhole cover.

[0035] In this embodiment, the working principle of a multi-functional integrated municipal well cover lifting device is as follows: When it is necessary to open the well cover, the clamping plate 43 parts of the two fixing components 40 are respectively passed through the lifting holes of the well cover, and then the square rod 56 is pressed to drive the blocking piece 53, the sliding rod 52 and the pushing block 54 to move. The pushing block 54 contacts the clamping plate 43 and squeezes the clamping plate 43 to rotate slightly. Subsequently, the driving motor 33 is started to drive the driving wheel 34 to rotate, driving the driven wheel 31, the rotating cylinder and the wire winding roller 21 to rotate, so that the rope 22 pulls the square cylinder 41 to rise. The upper part of the clamping plate 43 contacts the bottom surface of the well cover, and the square cylinder 41 continues to rise to drive the mounting plate 42 to rise, so that the upper part of the clamping plate 43 slides on the bottom surface of the well cover and rotates integrally around the fixed shaft 44, so that the clamping plate 43 is completely opened and contacts the bottom surface of the well cover. The driving motor 33 continues to drive the wire winding roller 21 to rotate, driving the well cover to rise, eliminating the need for manual lifting and reducing the labor intensity of the staff; When it is necessary to put the well cover back into the wellhead, the driving motor 33 drives the wire winding roller 21 to rotate, releases the rope 22, so that the fixing component 40 and the well cover gradually descend. After the well cover covers the wellhead, the driving motor 33 drives the wire winding roller 21 to continue rotating, so that the square cylinder 41 and the clamping plate 43 continue to descend. Under the action of the torsion spring, the clamping plate 43 resets. Subsequently, the driving motor 33 drives the wire winding roller 21 to rotate, retrieves the rope 22, and drives the fixing component 40 to rise through the lifting hole of the well cover.

[0036] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
