Description

Technical Field

[0001] This utility model relates to the field of municipal manhole cover opening technology, and in particular to a device for facilitating the opening of municipal manhole covers. Background Technology

[0002] In municipal engineering maintenance, the frequent opening and closing of manhole covers is a common yet challenging task. Traditional methods of opening manhole covers mostly rely on manual labor using simple pry bars and other tools. This method is not only labor-intensive but also inefficient. When faced with manhole covers that have not been opened for a long time, are rusted, or are installed too tightly, workers often need to spend a lot of time and energy to pry them open, and may even be injured due to improper force. In addition, in narrow work sites, conventional large-scale manhole cover opening equipment is difficult to operate, while simple tools cannot meet the operational needs, causing many inconveniences to municipal maintenance work. Therefore, developing a municipal manhole cover auxiliary opening device that is easy to use in various scenarios is of great practical significance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for facilitating the opening of municipal manhole covers. To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0004] A device for facilitating the opening of municipal manhole covers, comprising:

[0005] The support has threaded posts fixedly connected to both ends, and locking nuts are threadedly connected to the threaded posts.

[0006] Two booms, one end of which is rotatably connected to a corresponding threaded post, and the other end is hinged to a sling, with a hook fixedly connected to the end of the sling;

[0007] The handrail is rotatably mounted on the support, with the end curving upwards.

[0008] Furthermore, two truncated cones are fixedly connected to the support at intervals, and a ring is provided at one end of the handrail frame. The ring is fitted onto the support and located between the two truncated cones.

[0009] Furthermore, the end of the handrail is fixedly connected to an anti-slip pressing rod.

[0010] Furthermore, a bracket is installed at the bottom of the support, and rollers are installed at the bottom of the bracket.

[0011] Furthermore, the bracket is threadedly connected to the support for adjusting the height of the support.

[0012] Furthermore, the rollers are arranged in two parallel rows.

[0013] Furthermore, a stop ring is provided between the boom and the locking nut.

[0014] Furthermore, the handrail frame is configured in a Y-shape, and fixed rods are fixedly connected between the handrail frames.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] One end of the boom is rotatably connected to a threaded post, allowing for flexible angle adjustment. Combined with the sling and hook, it can accommodate manhole covers of different positions and shapes. Simultaneously, the handrail is rotatably mounted on the support, enabling flexible movement in confined work areas. Its upward-curving end design facilitates gripping and application of force by the operator, improving operational convenience. Using this device to open manhole covers effectively reduces the safety risks associated with manually prying them open, while also increasing opening efficiency and lowering labor and time costs for municipal maintenance.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] Figure 1 This is a schematic diagram of the main structure of an embodiment of the present utility model;

[0019] Figure 2 This is a top view of an embodiment of the present invention.

[0020] In the above-mentioned attached figures: support 1, threaded column 11, locking nut 12, truncated cone 13, stop ring 14, lifting rod 2, lifting sling 21, hook 22, handrail 3, ring 31, pressing rod 32, fixing rod 33, bracket 4, roller 41. Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] This utility model provides, for example Figure 1 , Figure 2 The illustrated device for facilitating the opening of municipal manhole covers includes:

[0023] Support 1, with threaded posts 11 fixedly connected to both ends, and locking nuts 12 threadedly connected to the threaded posts 11;

[0024] Two lifting rods 2, one end of which is rotatably connected to a corresponding threaded post 11, and the other end is hinged to a sling 21, with a hook 22 fixedly connected to the end of the sling 21;

[0025] Handrail 3 is rotatably mounted on support 1, with its end curving upwards.

[0026] When opening a municipal manhole cover, first place the support 1 in a suitable supporting position. Then, according to the position and shape of the manhole cover, rotate the lifting rod 2 to adjust its angle. By rotating the locking nut 12, fix the lifting rod 2 to the threaded post 11 of the support 1, so that the lifting cable 21 and the hook 22 can accurately hook onto the lifting ring of the manhole cover. Next, the operator holds the handrail 3 and rotates the handrail 3 according to the space of the work site. Using the lever principle, the manhole cover is slowly lifted by the lifting rod 2 and the lifting cable 21. In a narrow work site, the handrail 3 can be rotated flexibly to adapt to the limited operating space, thus successfully completing the opening of the manhole cover.

[0027] In this embodiment, to facilitate the adjustment and rotation of the handrail frame 3 according to the site environment, such as Figure 1 , Figure 2 As shown, two truncated cones 13 are fixedly connected to the support 1 at intervals. One end of the handrail 3 is provided with a ring 31, which is fitted onto the support 1 and located between the two truncated cones 13. This is to accommodate limited operating space.

[0028] In this embodiment, to facilitate the effortless pressing of the handrail frame 3 using the lever principle, such as... Figure 1 , Figure 2 As shown, the end of the handrail 3 is fixedly connected to an anti-slip pressing rod 32.

[0029] In another embodiment, such as Figure 1 As shown, a bracket 4 is installed at the bottom of the support 1, and a roller 41 is installed at the bottom of the bracket 4. This facilitates the removal of the manhole cover after it is lifted, and also makes it easier to move the opening device, making operation more labor-saving and convenient to use.

[0030] In this embodiment, as Figure 1 As shown, the bracket 4 is threadedly connected to the support 1 to adjust the height of the support 1. By rotating the bracket 4, the mating height between the bracket 4 and the support 1 can be adjusted, making it easy to adjust the height of the support 1 to meet on-site needs.

[0031] In this embodiment, in order to improve the support stability of support 1, such as Figure 1 As shown, there are two rollers 41 arranged side by side.

[0032] To facilitate locking the lifting rod 2 for repeatedly opening the same type of manhole cover, such as Figure 1 As shown, a stop ring 14 is provided between the boom 2 and the locking nut 12. This prevents the boom 2 from rotating and facilitates its use.

[0033] To improve the structural strength of the handrail frame 3, such as Figure 2 As shown, the handrail frame 3 is configured in a Y-shape, and fixed rods 33 are fixedly connected between the handrail frames 3.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
