Description

Technical Field

[0001] This utility model belongs to the technical field of lifting device structure, and particularly relates to a manhole cover lifting device for water conservancy pipelines. Background Technology

[0002] During water conservancy construction, it is necessary to divert liquids from water conservancy equipment to other locations. This diversion is often done through pipelines. To facilitate pipeline maintenance, vertical shafts may be installed, allowing operators easy access and preventing pedestrians from falling in. Manhole covers may be added to these shafts. However, opening these covers can be difficult due to their weight. To facilitate opening, a lifting device may be used. This device involves the operator attaching a lug to the cover, then rotating two screws. This moves a fixed base, which in turn moves the lug, opening the manhole. However, since both screws need to be rotated simultaneously, two operators may be required, making the process cumbersome. Therefore, we propose a manhole cover lifting device for water conservancy pipelines. Utility Model Content

[0003] This utility model provides a manhole cover lifting device for water conservancy pipelines. After the turntable rotates, the turntable drives the second gear to rotate through the first gear, which in turn drives the other second gear to rotate through the connecting rod. The second gear drives the first threaded sleeve to move the fixing plate up and down on the support frame surface through the third gear. The fixing plate pulls the manhole cover to move through the hook. When using this device, it is no longer necessary for two operators to rotate the support frame at the same time, which improves the convenience of operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a manhole cover lifting device for water conservancy pipelines, comprising a fixing plate, a sleeve provided in the middle of the fixing plate, and support seats symmetrically fixed at both ends of the sleeve, a turntable attached to the surface of the sleeve, and a first gear passing through one side of the sleeve fixed in the middle of the turntable, second gears symmetrically meshing at both ends of the first gear, and a connecting rod passing through the support seat fixed in the middle of each of the second gears, and another second gear fixed at the end of the connecting rod, and a third gear meshing at the end of the other second gear, and a first threaded sleeve fixed in the middle of the third gear, and cover plates threadedly installed at both ends of the fixing plate on the surfaces of the first threaded sleeve and the third gear, and a support frame passing through the cover plates, the first threaded sleeve and the fixing plate.

[0005] Furthermore, the fixed plate has a groove inside, and each groove is embedded with a slider. The surface of the slider is rotatably connected to a hook that passes through one side of the groove, and the surface of the hook is threaded with a second threaded sleeve.

[0006] Furthermore, the second threaded sleeve has symmetrical screw blocks fixed on its surface, and each screw block has an arc-shaped groove on its surface.

[0007] Furthermore, each hook is fixed with a rotating block on the side near the slider, and the surface of each rotating block is fitted with a rotating groove opened in the middle of the slider.

[0008] Furthermore, a handle is fixed to any side of the turntable surface, and the handle surface is provided with several sets of wavy grooves.

[0009] Furthermore, each of the support frames is fitted with an extension sleeve on the side that passes through the fixed plate, and the extension sleeve is fixed to the fixed plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This manhole cover lifting device for water conservancy pipelines is equipped with a turntable, a first gear, a second gear, a connecting rod, a third gear, and a first threaded sleeve. After the operator rotates the turntable, the turntable drives the second gear through the first gear to mesh with each other. The second gear, through the connecting rod, causes another second gear to mesh with the third gear. The third gear drives the first threaded sleeve to engage with the support frame, so that the fixing plate moves the manhole cover up and down through the hook, making it convenient for the operator to lift the manhole cover. When using it, it is no longer necessary for two operators to rotate the support frame at the same time, improving the convenience of operation.

[0012] 2. The manhole cover lifting device for water conservancy pipelines is equipped with a slider, a groove, and a second threaded sleeve. After the operator screws on the second threaded sleeve, the second threaded sleeve engages with the hook surface. After the second threaded sleeve no longer fixes the hook, the hook drives the slider to slide in the groove, allowing the hook to slide at the bottom of the fixed plate. The second threaded sleeve abuts against the surface of the fixed plate, fixing the position of the hook. This allows the operator to adjust the position of the hook according to the gap between the hanging holes on the manhole cover, thus improving the applicability of the device.

[0020] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings.

[0021] Example:

[0022] Please see Figure 1 - Figure 5A manhole cover lifting device for water conservancy pipelines includes a fixed plate 1, a housing 8 in the middle of the fixed plate 1, and support seats 6 symmetrically fixed to both ends of the housing 8. A turntable 9 is attached to the surface of the housing 8, and a first gear 12 passing through one side of the housing 8 is welded to the center of the turntable 9. Second gears 13 are symmetrically meshed on both ends of the first gear 12, and connecting rods 7 passing through the support seats 6 are welded to the middle of each of the second gears 13. Another second gear 13 is welded to the end of the connecting rod 7, and a third gear 14 is meshed at the end of the other second gear 13. A first threaded sleeve 5 is welded to the middle of the third gear 14. Cover plates 4, which are bolted to both ends of the fixed plate 1, are fitted on the surfaces of the first threaded sleeve 5 and the third gear 14. Support frames 3 pass through the cover plates 4, the first threaded sleeve 5, and the fixed plate 1. When the operator needs to lift the manhole cover, the operator hangs the hook 2 on the hanging lug of the manhole cover, and then the operator rotates the turntable 9. The turntable 9 drives the first gear 12 inside the housing 8 to rotate. When the first gear 12 and the second gear 13 mesh with each other, the first gear 12 drives the connecting rod 7 to rotate through the second gear 13. The other second gear 13 fixed to the other end of the connecting rod 7 rotates. After the other second gear 13 rotates, it meshes with the third gear 14, causing the third gear 14 to rotate. When the third gear 14 rotates, it drives the first threaded sleeve 5 to rotate. When the first threaded sleeve 5 rotates, the internal thread on the inner wall of the first threaded sleeve 5 and the thread on the surface of the support frame 3 engage with each other, causing the first threaded sleeve 5 to move up and down on the surface of the support frame 3. When the first threaded sleeve 5 moves, it drives the fixed plate 1 to move up and down, causing the fixed plate 1 to drive the hook 2 to move. The hook 2 pulls the manhole cover to move, making it convenient for the operator to lift the manhole cover. When using the manhole cover, it is no longer necessary for two operators to rotate the support frame 3 at the same time, improving the convenience of the operator.

[0023] In other embodiments, the fixed plate 1 has a groove 11 inside, and each groove 11 is embedded with a slider 18. The surface of the slider 18 is rotatably connected to a hook 2 passing through one side of the groove 11. The surface of the hook 2 is threaded with a second threaded sleeve 16. When the operator needs to adjust the position of the hook 2, the operator first twists the second threaded sleeve 16 so that the second threaded sleeve 16 and the thread on the surface of the hook 2 are threaded together. The second threaded sleeve 16 moves on the surface of the hook 2, separating the second threaded sleeve 16 from the fixed plate 1. Then the operator pulls the hook 2, and the hook 2 drives the slider 18 to slide in the groove 11, so that the hook 2 slides under the fixed plate 1, thereby adjusting the distance between the two sets of hooks 2. When the hook 2 moves to the appropriate position, the operator twists the second threaded sleeve 16 again. The second threaded sleeve 16 and the thread on the surface of the hook 2 are threaded together so that the second threaded sleeve 16 abuts against the surface of the fixed plate 1, fixing the position of the hook 2. This makes it convenient for the operator to adjust the position of the hook 2 according to the gap between the hanging ears on the manhole cover, thus improving the usability of the device.

[0024] In other embodiments, the second threaded sleeve 16 is symmetrically welded with screw blocks 17, and each screw block 17 has an arc-shaped groove on its surface. When the operator rotates the second threaded sleeve 16, the operator places his hand on the screw block 17. The operator's hand fits into the groove on the surface of the screw block 17. The groove on the surface of the screw block 17 helps to avoid the operator's hand, increasing the comfort of the operator's hand fitting into the surface of the screw block 17. Then the operator rotates the screw block 17, and the screw block 17 drives the second threaded sleeve 16 to rotate, improving the operator's comfort in rotating the second threaded sleeve 16.

[0025] In other embodiments, a rotating block 20 is welded to the side of the hook 2 near the slider 18, and the surface of the rotating block 20 is fitted with a rotating groove 19 opened in the middle of the slider 18. When the operator pushes the hook 2, the hook 2 drives the rotating block 20, which is set as a disc, to rotate in the rotating groove 19, which is set as a disc-shaped groove, so as to facilitate the adjustment of the hook opening direction of the hook 2 and make it easy to align the hook opening direction of the hook 2 with the position of the hanging ear opening opened on the surface of the manhole cover.

[0026] In other embodiments, a handle 10 is welded to any side of the surface of the turntable 9, and the surface of the handle 10 is provided with several sets of wavy grooves. When the operator rotates the turntable 9, the operator holds the handle 10. After the operator holds the handle 10, the several sets of wavy grooves on the surface of the handle 10 increase the friction of the operator's hand on the surface of the handle 10, thereby improving the stability of the operator's hand on the surface of the handle 10. Then the operator rotates the handle 10, which drives the turntable 9 to rotate, causing the turntable 9 to drive the first gear 12 to rotate, making it convenient for the operator to rotate the turntable 9.

[0027] In other embodiments, an extension sleeve 15 is fitted on the side of the support frame 3 that passes through the fixed plate 1 and the cover plate 4, and the extension sleeve 15 is welded to the fixed plate 1. When the fixed plate 1 and the cover plate 4 slide on the surface of the support frame 3, the extension sleeve 15 slides on the surface of the support frame 3. The extension sleeve 15 increases the contact area of ​​the support frame 3 on the side that passes through the cover plate 4 and the fixed plate 1, and increases the stability of the cover plate 4 and the fixed plate 1 sliding on the surface of the support frame 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
