Description

Technical Field

[0001] This utility model relates to a manhole cover lifting device, specifically a manhole cover lifting device for municipal engineering. Background Technology

[0002] In the daily maintenance of municipal engineering projects, opening and closing manhole covers is an extremely common and important task. However, the traditional method of pulling up manhole covers has many serious drawbacks.

[0003] From a mobility perspective, traditional manhole cover lifting tools mostly lack convenient mobile design. Many tools are simply manual implements, such as bulky crowbars, which can only be moved manually when needed from one construction site to another. These tools are large and heavy, not only consuming manpower but also being extremely inconvenient to move, seriously affecting construction efficiency. In addition, due to the lack of specialized moving aids, the tools are prone to bumping into the ground or other facilities when moving them on the construction site, causing damage to the tools and even leading to safety accidents.

[0004] Therefore, there is an urgent need in the market for a better manhole cover lifting device for municipal engineering. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a manhole cover lifting device for municipal engineering.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a manhole cover lifting device for municipal engineering: including a bottom support plate;

[0007] The projection of the bottom support plate in the side view direction presents an inverted V shape;

[0008] A core support frame is fixedly installed in the middle of the bottom support plate, and a handle is provided on the top of the core support frame;

[0009] The core support frame is provided with an elongated through hole, which extends from the lower part of the core support frame to the upper middle part of the core support frame;

[0010] The top of the elongated through hole is provided with a pull rope, and the end of the pull rope is fixed with a T-shaped hook.

[0011] As an improvement, the lower sides of the elongated through hole are symmetrically provided with blocking grid plates.

[0012] As an improvement, the front plate of the bottom support plate is symmetrically provided with core traveling wheels on both sides.

[0013] As an improvement, support blocks are provided on the lower sides of both sides of the rear plate of the bottom support plate.

[0014] As an improvement, the front plate is provided with a front weight reduction through hole.

[0015] As an improvement, the rear plate is provided with a rear weight reduction through hole.

[0016] The advantages of this invention compared to existing technologies are as follows: Superior performance: During use, the design of the T-shaped hook and the drainage hole of the manhole cover ensures a tight connection when the manhole cover is pulled up, preventing it from falling off and protecting the safety of operators and the surrounding environment. Furthermore, in both moving and placing states, the pull rope and T-shaped hook can be stored within the placement barrier grating, avoiding safety hazards caused by accidental falls.

[0017] The device features a rational structural design: the bottom support plate has an inverted V-shape when viewed from the side. This unique structural design allows the device to achieve stable placement and flexible movement during placement and use, thanks to the coordinated operation of the core traveling wheels on both sides of the front plate and the support blocks on the lower sides of the rear plate. For example, in the placement state, both components work together to support the ground, ensuring the stability of the device; in the movement and use state, the tilting device changes the support point, facilitating operation.

[0018] High ease of operation: The device is equipped with core wheels, allowing operators to easily push the handle by simply tilting the device forward to allow the wheels to support the ground. The use of the wheels for movement significantly saves manpower and time. Furthermore, the design of the pull rope and T-hook, along with the storage function for the barrier grid panels, makes the operation process simple, clear, and easy to learn.

[0019] Weight reduction design optimization: The front weight reduction through holes on the front plate and the rear weight reduction through holes on the rear plate effectively reduce the overall weight of the device without affecting the structural strength of the device, further improving the convenience of operation, and also reducing material costs.

[0028] Referring to the accompanying drawings, a manhole cover lifting device for municipal engineering includes a bottom support plate 1. The projection of the bottom support plate 1 in the side view direction presents an inverted V shape. The front plate 2 of the bottom support plate 1 is symmetrically provided with core traveling wheels 3 on both sides. The rear plate 4 of the bottom support plate 1 is provided with support blocks 5 on both lower sides. The front plate 2 is provided with a front weight-reducing through hole 6, and the rear plate 4 is provided with a rear weight-reducing through hole 7.

[0029] The bottom support plate 1 is fixedly provided with a core support frame 8 in the middle, and the top of the core support frame 8 is provided with a handle 9.

[0030] The core support frame 8 is provided with an elongated through hole 10, which extends from the lower part of the core support frame 8 to the upper middle part of the core support frame 8. The lower two sides of the elongated through hole 10 are symmetrically provided with blocking grid plates 11. The top of the elongated through hole 10 is provided with a pull rope 12, and the end of the pull rope 12 is fixed with a T-shaped hook 13.

[0031] Initial placement: Place the manhole cover lifting device at the desired operating location. At this time, the bottom support plate 1 is inverted V-shaped when viewed from the side. The core traveling wheels 3 symmetrically arranged on both sides of the front plate 2 and the support blocks 5 arranged on the lower sides of both sides of the rear plate 4 are in contact with the ground, so that the device is placed stably.

[0032] The lower part of the pull rope 12 and the T-shaped hook 13 fixed at the end are placed inside the blocking grid plate 11 symmetrically arranged on both sides of the lower part of the elongated through hole 10, and are in a stored state.

[0033] Movement process: Confirm that the lower part of the pull rope 12 and the T-hook 13 are still inside the blocking grid plate 11 to ensure that they will not fall off accidentally or cause obstruction during the movement.

[0034] The operator tilts the device forward so that the core traveling wheels 3 on both sides of the front plate 2 support the ground independently, while the support blocks 5 on the lower sides of the rear plate 4 are lifted off the ground.

[0035] The operator pushes the handle 9, using the rolling of the core walking wheels 3 to easily move the device on the ground to the position where the manhole cover needs to be lifted.

[0036] Operation: After reaching the manhole cover location, the operator removes the lower part of the pull rope 12 and the T-shaped hook 13 from the place where the blocking grid plate 11 is placed, in preparation for subsequent operations.

[0037] Tilt the device backward so that the core walking wheels 3 on both sides of the front plate 2 are off the ground, while the support blocks 5 on the lower sides of the rear plate 4 contact the ground and stabilize the device.

[0038] Carefully observe the position of the drain hole on the manhole cover, and accurately insert the T-hook 13 into the drain hole of the manhole cover, ensuring that the T-hook 13 fits tightly with the drain hole to prevent it from falling off during the pulling process.

[0039] The operator holds the handle 9 with both hands and lifts it upwards with even force. Through the transmission of the pull rope 12, the force is applied to the T-shaped hook 13, thereby moving the manhole cover upwards and achieving the purpose of lifting the manhole cover.

[0040] After the operation is completed, if the device needs to be moved, repeat the moving process steps; if it is no longer in use, put the T-hook 13 back into the placement blocking grid plate 11 to return the device to its initial placement state.

[0041] Excellent performance: During use, the design of the T-shaped hook 13 and the drainage hole of the manhole cover ensures a tight connection when the manhole cover is pulled up, preventing it from falling off and ensuring the safety of operators and the surrounding environment. Moreover, when moving or placing, the pull rope 12 and the T-shaped hook 13 can be stored inside the placement barrier grating plate 11, avoiding safety hazards caused by accidental falls.

[0042] The structure is rationally designed: the bottom support plate 1 of the device has an inverted V-shape when viewed from the side. This unique structural design allows the device to achieve stable placement and flexible movement during placement and use, through the coordinated operation of the core traveling wheels 3 on both sides of the front plate 2 and the support blocks 5 on the lower sides of the rear plate 4. For example, in the placement state, both support the ground together to ensure the stability of the device; in the movement and use state, the support point can be changed through the tilting device to facilitate operation.

[0043] High ease of operation: The device is equipped with core walking wheels 3. When moving, the operator only needs to tilt the device forward so that the core walking wheels 3 support the ground to easily push the handle 9. The rolling movement of the wheels greatly saves manpower and time costs. At the same time, the design of the pull rope 12 and T-shaped hook 13, as well as the storage function for placing the blocking grid plate 11, makes the operation process simple and clear, and easy to learn.

[0044] Weight reduction design optimization: The front weight reduction through hole 6 on the front plate 2 and the rear weight reduction through hole 7 on the rear plate 4 effectively reduce the overall weight of the device without affecting the structural strength of the device, further improving the convenience of operation, and also reducing material costs.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
