[0003] Currently, opening manhole covers requires the use of handheld prying devices or hydraulic mechanisms. However, these opening devices are inconvenient to carry, or some are difficult to operate, which can easily affect the efficiency of operators in emergency situations. Utility Model Content

[0004] This application aims to at least partially solve the technical problem of impaired manhole cover opening efficiency. To this end, this application provides a manhole cover opening tool and a manhole cover device.

[0005] This application provides a cover-opening tool for opening manhole covers with lifting holes, including:

[0006] Load-bearing components;

[0007] The abutment member has an abutment portion and a rod portion with one end fixed to the abutment portion. The other end of the rod portion is detachably connected to the force-bearing member. The rod portion is used to pass through the cover lifting hole. The abutment member and the force-bearing member are respectively used to abut against the two ends of the manhole cover.

[0008] A connecting rope, with its two ends connected to the force-bearing component and the abutment part, respectively.

[0009] In some or more embodiments, the rod and the force-bearing member are threadedly connected.

[0010] In some or more embodiments, the force-bearing member includes:

[0011] The connecting part is detachably connected to one end of the rod.

[0012] The rod-shaped handheld part has its peripheral wall connected and fixed to the connecting part, and both ends protrude from the connecting part.

[0013] In some or more embodiments, the force-bearing member further includes:

[0014] The ring-shaped part is fixedly connected to the connecting part and also fixedly connected to one end of the connecting rope.

[0015] In some or more embodiments, the force-bearing member is further provided with a force-bearing through hole.

[0016] In some or more embodiments, the length of the connecting rope is greater than the length of the pole.

[0017] In some or more embodiments, the abutment portion is rod-shaped and its peripheral wall is connected and fixed to the rod portion, and both ends of the abutment portion protrude from the rod portion.

[0018] This application also provides a manhole cover device, comprising:

[0019] The manhole cover is provided with at least one lifting hole, which connects the two ends of the manhole cover;

[0020] As described above, the handle of the manhole cover is inserted through the lifting hole, and the force-bearing member and the abutting part are respectively used to abut against both ends of the manhole cover.

[0021] In some or more embodiments, the end of the manhole cover near the force-bearing member is provided with a mating groove, the mating groove communicating with the cover lifting hole and used for insertion with the force-bearing member.

[0022] In some or more embodiments, the manhole cover has a positioning groove at one end near the abutment portion, the positioning groove being connected to the cover lifting hole and used for insertion into the abutment portion.

[0023] The beneficial effects provided by one or more embodiments of this application are as follows:

[0024] When the manhole cover actually covers the passage to underground facilities, the rod of the abutment member in the opening tool is passed through the lifting hole of the manhole cover. The abutment part, which is fixed to one end of the rod, can be located at one end of the manhole cover. Then, the force-bearing member is detachably connected to the other end of the rod. The abutment parts of the force-bearing member and the abutment member can be located at opposite ends of the manhole cover. The abutment member and the force-bearing member are used to abut against both ends of the manhole cover, preventing the opening tool from detaching from the manhole cover. The manhole cover is then used to close the passage to underground facilities. When the manhole cover is in the closed passage state, the force-bearing member of the opening tool can be supported on the manhole cover. If the operator needs to open the manhole cover, they can lift the force-bearing member, causing the entire opening tool to move until the abutment part abuts against one end of the manhole cover. The opening tool can then transfer the force through the abutment part to one end of the manhole cover to open it. Opening the cover is faster, does not require carrying it with the operator, and effectively improves the efficiency of opening the cover. The cover-opening tool also has connecting ropes at both ends that connect the force-bearing component and the abutment part, respectively. When it is necessary to separate the cover-opening tool from the well cover, the force-bearing component and the rod can be separated first. The connecting ropes ensure that the force-bearing component and the rod will not fall off in the separated state. Then, the rod can be pulled out from the cover-lifting hole to separate from the well cover. The operation is convenient and safe, and it is not easy for the rod to detach from the well cover and affect the cover-opening process. Overall, it can effectively improve the efficiency of opening the well cover and solve the technical problem of the cover-opening efficiency being affected to a certain extent.

[0036] The present application will now be described in conjunction with the accompanying drawings:

[0037] Figure 1 This application shows a schematic diagram of the structure of a lid-opening tool in some or certain embodiments. Figure 2 This illustration shows a schematic diagram of the usage state of a lid-opening tool according to some embodiments or certain embodiments of this application. Figure 3 This illustration shows a schematic diagram of the usage state of another lid-opening tool in some embodiments or certain embodiments of this application, with reference to... Figures 1-3 This application provides a cover-opening tool for opening a well cover 10 with a cover-lifting hole 101, comprising:

[0038] Component 1 under stress.

[0039] The abutting member 2 is provided with an abutting part 21 and a rod part 22 that is fixed to the abutting part 21 at one end. The other end of the rod part 22 is detachably connected to the force-bearing member 1. The rod part 22 is used to pass through the cover lifting hole 101. The abutting member 2 and the force-bearing member 1 are respectively used to abut the two ends of the well cover 10.

[0040] The connecting rope 3 is connected at both ends to the force-bearing component 1 and the abutment part 21, respectively.

[0041] When the manhole cover 10 actually covers the passage leading to the underground facility, the rod 22 of the abutment member 2 in the opening tool is passed through the lifting hole 101 of the manhole cover 10. The abutment part 21 of the abutment member 2, which is fixed to one end of the rod 22, can be located at one end of the manhole cover 10. Then, the force-bearing member 1 is detachably connected to the other end of the rod 22. The abutment part 21 of the force-bearing member 1 and the abutment part 2 can be located at both ends of the manhole cover 10 respectively. The abutment member 2 and the force-bearing member 1 are used to abut the two ends of the manhole cover 10 respectively, so that the opening tool will not detach from the manhole cover 10. Then, the manhole cover 10 is closed to seal the passage leading to the underground facility. When the manhole cover 10 is in a closed passage state, the force-bearing component 1 of the opening tool can be supported on the manhole cover 10. If the operator needs to open the manhole cover 10, he can lift the force-bearing component 1 so that the opening tool moves as a whole to the contact part 21 and abuts against one end of the manhole cover 10. The opening tool can transmit the force to one end of the manhole cover 10 through the contact part 21 to open the manhole cover 10. The opening is faster and does not need to be carried around, which effectively improves the opening efficiency. The cover-opening tool also has a connecting rope 3 that connects the force-bearing component 1 and the abutment part 21 at both ends. When it is necessary to separate the cover-opening tool from the well cover 10, the force-bearing component 1 and the rod part 22 can be separated first. The connecting rope 3 ensures that the force-bearing component 1 and the rod part 22 will not fall off in the separated state. Then, the rod part 22 is pulled out from the cover-lifting hole 101 to separate from the well cover 10. The operation is convenient and safe. It is also less likely that the rod part 22 will detach from the well cover 10 and affect the cover-opening process. Overall, it can effectively improve the cover-opening efficiency of the well cover 10 and solve the technical problem of the cover-opening efficiency being affected to a certain extent.

[0042] Furthermore, since the opening tool adopts the above structure, the connection or separation between the opening tool and the well cover 10 will not affect the opening tool itself or the well cover 10, making it convenient to use.

[0043] It should be noted that, Figure 2 The opening tool and the manhole cover 10 are in a state where the manhole cover 10 has closed the passage to the underground facility. The opening tool is in a state where the force-bearing component 1 of the opening tool can be supported at one end of the manhole cover 10. Figure 3 The opening tool can be in a state where the force-bearing component 1 is lifted under the action of an external force, and the abutting part 21 of the abutting component 2 abuts against the manhole cover 10. The manhole cover 10 may tend to move upward and open due to the force from the abutting component 2. The external force on the force-bearing component 1 can be applied to the force-bearing component 1 manually or by machine.

[0044] Figure 4 This application shows a schematic diagram illustrating the connection state between a force-bearing member and a rod in some or certain embodiments. (Refer to...) Figure 4 In some or all embodiments, the rod 22 is threadedly connected to the force-bearing member 1.

[0045] The rod 22 is threaded to the force-bearing component 1, which ensures good connection strength between the rod 22 and the force-bearing component 1, and also facilitates the assembly and disassembly of the rod 22 and the force-bearing component 1.

[0046] In some or more embodiments, the rod 22 and the force-bearing member 1 can also be detachably connected by means of a pin or key connection. This also allows for a detachable connection between the rod 22 and the force-bearing member 1.

[0047] In some or more embodiments, the force-bearing member 1 includes:

[0048] The connecting part 11 is detachably connected to one end of the rod part 22.

[0049] The rod-shaped hand-held part 12 is fixedly connected to the connecting part 11 with its peripheral wall, and both ends protrude from the connecting part 11.

[0050] The connecting part 11 can be detachably connected to the rod part 22. The peripheral wall of the rod-shaped hand handle 12 is connected and fixed to the connecting part 11, and both ends of the rod-shaped hand handle 12 protrude from the connecting part 11, which facilitates hand operation and helps to improve the efficiency of opening the cover.

[0051] In some or more embodiments, the connecting part 11 may be cylindrical and one end may be fixedly connected to the rod-shaped handheld part 12. The inner hole of the connecting part 11 may be a threaded hole that is threadedly connected to one end of the rod part 22. It is simple to manufacture and easy to operate.

[0052] In some or more embodiments, the force-receiving member 1 may also include a cylindrical connecting portion 11 and an annular handle portion, the annular handle portion being coaxially connected to the connecting portion 11. It may also be connected to the rod portion 22, forming an integral unit with the tool for lifting the cover via the force-receiving member 1. Alternatively, the force-receiving member 1 may be spherical, etc.

[0053] In some or more embodiments, the force-bearing member 1 further includes:

[0054] The annular part 13 is fixedly connected to the connecting part 11 and is also fixedly connected to one end of the connecting rope 3.

[0055] The annular portion 13 provides a connection space for the connecting rope 3, which facilitates the connection and installation of the connecting rope 3. The annular portion is located in the connecting portion 11, and the annular portion is spaced apart from the rod-shaped handheld portion 12, so that interference is less likely to occur.

[0056] It should be noted that the connection and fixation between the end of the connecting rope 3 and the annular portion 13 or the abutment portion 21 can be achieved by tying the end of the connecting rope 3 to the annular portion 13 or the abutment portion 21. Alternatively, a connecting hole (not shown in the figure) for the end of the connecting rope 3 to pass through can be provided on the abutment portion 21. The connecting rope 3 can be configured as a wear-resistant connecting rope with a certain degree of elasticity as required.

[0057] In some or more embodiments, the force-bearing member 1 is further provided with a force-bearing through hole 14.

[0058] The force-bearing component 1 is also provided with a force-bearing through hole 14, which can be used in conjunction with, for example, a rod-shaped structure, inserted into the force-bearing through hole 14, and then the opening tool and the well cover 10 can be lifted by the rod-shaped structure. The force-bearing through hole 14 can increase the force-bearing points of the opening tool.

[0059] In some or more embodiments, the force-bearing through hole 14 may be provided on the rod-shaped handheld part 12 or the connecting part 11 as needed. When the force-bearing through hole 14 is provided on the connecting part 11, the connecting part 11 may be columnar and have a threaded hole at one end. The force-bearing through hole 14 may be provided at the end of the connecting part 11 where no threaded hole is provided.

[0060] In some or more embodiments, the length of the connecting rope 3 is greater than the length of the rod 22. The connecting rope 3 can be in a slack state, and the connecting rope 3 also has a certain length. When the force-bearing member 1 and the rod 22 are separated, there can be a certain gap between the force-bearing member 1 and the rod 22, which can reduce the occurrence of interference during operation.

[0061] In some or more embodiments, the abutment portion 21 is rod-shaped and its peripheral wall is connected and fixed to the rod portion 22, and both ends of the abutment portion 21 protrude from the rod portion 22.

[0062] The abutment part 21 is rod-shaped, which has low processing and manufacturing costs and is also easy to achieve abutment with the manhole cover 10.

[0063] In some or more embodiments, the abutment portion 21 may also be shaped like a circular plate or a ring, etc., thus achieving abutment with the manhole cover 10.

[0064] Based on the same inventive concept, this application also provides a manhole cover device, comprising:

[0065] The manhole cover 10 is provided with at least one lifting hole 101, which connects the two ends of the manhole cover 10.

[0066] As described above, the handle 22 of the opening tool passes through the lifting hole 101, and the force-bearing member 1 and the abutment part 21 are located at the two ends of the manhole cover 10, respectively.

[0067] The structure and corresponding technical effects of the cover opening tool can be referred to above, and will not be repeated here. The rod 22 of the cover opening tool passes through a lifting hole 101 of the well cover 10, and one end of the rod 22 is connected to a fixed abutment part 21, and the force-bearing member 1 is detachably connected to the other end of the rod 22. These are used to abut the two ends of the well cover 10, making it difficult for the cover opening tool to detach from the well cover 10 and facilitating the cover opening operation.

[0068] It should be noted that the engagement state between the manhole cover 10 and the opening tool can be referred to the aforementioned... Figure 2 and Figure 3 Details will not be provided here.

[0069] Figure 5 This application shows a schematic diagram of the structure of a manhole cover in some or certain embodiments, with reference to... Figure 5 It is understood that in some or more embodiments, the end of the manhole cover 10 near the force-bearing member 1 is provided with a mating groove 102, which is connected to the cover lifting hole 101 and is used to be inserted into the force-bearing member 1.

[0070] The addition of the mating groove 102 facilitates the support and positioning of the force-bearing component 1. In some cases, the depth of the mating groove 102 can be the same as the height of the force-bearing component 1, so that the force-bearing component 1 can be embedded in the mating groove 102 of the manhole cover 10, ensuring the flatness of the end face of the manhole cover 10 and improving the applicability of the opening tool.

[0071] It should be noted that the force-bearing component 1 protrudes from the surface of the manhole cover 10, which will not affect the use of manhole covers 10 where large vehicles do not travel on the surface. Adding a mating groove 102 to the surface of the manhole cover 10 for insertion with the force-bearing component 1 can also improve the versatility of the manhole cover device.

[0072] In some or more embodiments, the lifting hole 101 may be a circular hole, and both the force-bearing member 1 and the abutment part 21 may be rod-shaped, with the axial length of both the force-bearing member 1 and the abutment part 21 being greater than the diameter of the lifting hole 101. This ensures stable contact between the force-bearing member 1 or the abutment part 21 and the manhole cover 10, and that the opening tool will not detach from the manhole cover 10 when the force-bearing member 1 and the rod part 22 are in a connected state.

[0073] In some or more embodiments, if the lifting hole 101 is irregularly shaped, the maximum size of the force-bearing member 1 and the maximum size of the abutment portion 21 are both larger than the maximum size corresponding to the lifting hole 101. The force-bearing member 1 and the abutment portion 21 can stably abut against both ends of the manhole cover 10 and are not easily detached from the manhole cover 10.

[0074] In some or more embodiments, the end of the manhole cover 10 near the abutment portion 21 is provided with a positioning groove (not shown in the figure), the positioning groove is connected to the lifting hole 101 and is used to insert into the abutment portion 21.

[0075] The manhole cover 10 has a positioning groove at one end near the abutment part 21. The positioning groove can be inserted into the abutment part 21. During the overall movement of the opening tool, the abutment part 21 can be moved into the positioning groove, which can improve the force transmission effect between the abutment part 21 and the manhole cover 10 and help improve the opening efficiency.

[0076] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0077] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
