[0025] refer to Figures 1 to 4 A manhole cover opening device according to a preferred embodiment of the present utility model will be described in detail below. The manhole cover opening device includes at least one folding component 10, at least one driving component 20 and a pull cover component 30.

[0026] like Figure 1 and Figure 2 As shown, the folding assembly 10 includes a folding seat 11 , two folding plates 12 and at least one fixing member 13 , wherein the folding seat 11 is drivably installed above the driving member 20 to move up and down under the drive of the driving member 20 .

[0027] By way of example, the driving member 20 is implemented as a cylinder or a jack.

[0028] The two folding plates 12 are relatively mounted on both sides of the folding seat 11, and each of the folding plates 12 is formed with at least two fixing holes 1201, and the fixing holes 1201 are adapted to the fixing member 13. One end of the sliding cover assembly 30 is rotatably mounted on the upper end of the folding seat 11, and the end of the sliding cover assembly 30 is located between the two folding plates 12. The sliding cover assembly 30 can be folded toward the folding seat 11 with the connection between the folding seat 11 and the sliding cover assembly 30 as an axis to reduce the space volume occupied for easy storage and transportation. All the fixing holes 1201 are arranged at the part corresponding to the folding plate 12 and the rotating sliding cover assembly 30 and are at the same distance from the axis of the sliding cover assembly 30 when rotating. One of the fixing holes 1201 is closest to the driving member 20, and the remaining fixing holes 1201 are all located on the side of the fixing hole 1201 closest to the driving member 20 close to the entire sliding cover assembly 30. The fixing member 13 can pass through any of the fixing holes 1201 of the two folding plates 12 and penetrate the sliding cover assembly 30 to adjust the angle of the sliding cover assembly 30 relative to the folding seat 11 and lock the sliding cover assembly 30 to the folding seat 11. When the sliding cover assembly 30 is at an angle relative to the folding seat 11, the fixing member 13 is inserted into the folding plate 12 and penetrates the sliding cover assembly 30, and the manhole cover opening device is in an unfolded state to facilitate the sliding cover; when the sliding cover assembly 30 is folded on the folding seat 11 and fixed by the fixing member 13, the manhole cover opening device is in a folded state to prevent the angle between the sliding cover assembly 30 and the folding seat 11 from changing during transportation, and to avoid damage to itself or other items due to shaking during transportation. At the same time, the sliding cover assembly 30 can hook the manhole cover, so that when the driving member 20 drives the folding seat 11 to rise, at least part of the sliding cover assembly 30 is driven by the folding seat 11 to rise, thereby pulling up the manhole cover.

[0029] By way of example, the fixing element 13 is implemented as a fixing pin.

[0030] It can be understood by those skilled in the art that when the manhole cover opening device is provided with only one folding assembly 10 and one driving member 20, one end of the pull cover assembly 30 is rotatably mounted on the upper end of the folding seat 11, and the other end is directly abutted against the ground or suspended above the ground due to the plugging action of the fixing member 13, so as to adapt to different terrain environments, such as dirty environments; when the driving member 20 drives the folding seat 11 to rise, the end of the pull cover assembly 30 on which the folding seat 11 is mounted moves upward, so that the manhole cover hooked by the pull cover assembly 30 can be pulled up. When the manhole cover opening device needs to be transferred, the fixing member 13 is pulled out from the fixing hole 1201 and the pull cover assembly 30, so that the pull cover assembly 30 rotates with the connection between its own end and the folding seat 11 as the rotation axis, so that the pull cover assembly 30 moves closer to the driving member 20 and folds together, which is convenient for maintenance personnel to carry.

[0031] Preferably, if Figure 1 As shown, the number of the folding assembly 10 and the driving member 20 is implemented as two. Each folding assembly 10 is arranged above one driving member 20, and the two ends of the cover pull assembly 30 are rotatably mounted on the two folding assemblies 10, so that when the two driving members 20 are driven at the same time, the cover pull assembly 30 and the folding assembly 10 rise at the same time, thereby accelerating the efficiency of the cover pull.

[0032] More preferably, the number of the fixing holes 1201 on each folding disk 12 is implemented as a plurality. In this way, when the manhole cover opening device opens the manhole cover, the user can lock the angle between the pull cover assembly 30 and the two driving members 20 by inserting the fixing member 13 into different fixing holes 1201, so that the manhole cover opening device is in an unfolded state and the unfolded state is fixed. At the same time, in this unfolded state, the angle between the pull cover assembly 30 and the two driving members 20 can be set differently to match the actual terrain, thereby increasing the applicable range of the manhole cover opening device.

[0033] Preferably, when the driving member 20 is implemented as a jack and the number of the driving members 20 is implemented as two, each of the driving members 20 has a manual part 21, and the manual part 21 can be manually operated by maintenance personnel. The two manual parts 21 are connected together, and the maintenance personnel can operate the two manual parts 21 at the same time. In this way, the rising distances of the two driving members 20 will be the same, and there is no need for maintenance personnel to operate one by one, thereby improving efficiency.

[0034] Preferably, the sliding cover assembly 30 includes a sliding cover body 31 and at least one sliding cover member 32, wherein one end of the sliding cover body 31 is rotatably mounted on the folding seat 11. The sliding cover member 32 is mounted below the middle of the sliding cover body 31, and the sliding cover member 32 can pull the manhole cover and rise as the end of the sliding cover body 31 mounted on the folding seat 11 rises.

[0035] By way of example, the sliding cover 32 is implemented as a hook lock.

[0036] Preferably, if Figure 3 As shown, the cover body 31 includes at least one folding member 311 and a sliding member 312, wherein the folding member 311 is configured as a hollow body, and the sliding member 312 is configured to be inserted into and slide on the folding member 311. One end of the folding member 311 away from the sliding member 312 is rotatably connected to the folding seat 11. The cover member 32 is mounted on the sliding member 312, and the cover member 32 can approach or move away from the folding member 311 as the sliding member 312 slides, so as to adjust the relative position between the cover member 32 and the manhole cover, facilitate the cover pulling, and increase the applicable range of the manhole cover opening device.

[0037] Specifically, Figure 4 As shown, the folding member 311 forms a row of locking holes 31101 along the sliding direction of the sliding member 312, and a pressing block 3121 is provided on one side of the sliding member 312 corresponding to the locking hole 31101, and the pressing block 3121 is adapted to the locking hole 31101, and the pressing block 3121 can be compressed and reset, so that the pressing block 3121 protrudes from the surface of the sliding member 312 in the reset state, and the pressing block 3121 is flush with or recessed in the surface of the sliding member 312 in the compressed state. When the sliding member 312 is pulled by the maintenance personnel, the pressing block 3121 moves along the pulling direction and moves in and out of the plurality of locking holes 31101 in sequence through compression and reset, and when the maintenance personnel stops pulling the sliding member 312, the pressing block 3121 is in one of the locking holes 31101, thereby preventing the sliding member 312 from sliding itself.

[0038] As an example, the pressing block 3121 is implemented as a button with a spring.

[0039] Preferably, the cover pull piece 32 has a hanging portion 321, the hanging portion 321 is configured as a hollow body, and the cover pull piece 32 is slidably sleeved on the sliding member 312, so that the position of the cover pull piece 32 can be more easily adjusted so that the cover pull piece 32 is aligned with the manhole cover.

[0040] It can be understood that when the maintenance personnel use the manhole cover opening device, the maintenance personnel first fix the angle between the folding member 311 and the driving member 20 through the fixing member 13; then the maintenance personnel pull the sliding member 312 out of the folding member 311, so that the position of the cover puller 32 is adjusted to be directly above the manhole cover, and at the same time the driving member 20 is driven, at least one end of the folding member 311 and the hanging member 312 and the cover puller 32 are raised, and finally the cover puller 32 pulls up the manhole cover.

[0041] Preferably, when the number of the folding assembly 10 and the driving member 20 is two, the number of the folding members 311 is two. One end of each folding member 311 is rotatably mounted on one of the folding seats 11, and both ends of the sliding member 312 are slidably inserted into the other ends of the two folding members 311, thereby facilitating disassembly and installation.

[0042] Preferably, the manhole cover opening device also includes movable components 40 corresponding to the number of the driving components 20, each of the movable components 40 is installed under one of the driving components 20, and the movable components 40 can drive the driving components 20 to move, thereby facilitating maintenance personnel to move the manhole cover opening device.

[0043] Preferably, the moving member 40 includes a moving seat 41 and a plurality of moving members 42, the moving members 42 are rotatably mounted below the moving seat 41, and the moving seat 41 is configured to be driven by the moving members 42 that can rotate and roll on the ground to move the manhole cover to another place after opening the manhole cover. The moving seat 41 is configured to have a predetermined length and width, and the driving member 20 is mounted on the upper surface of the moving seat 41, so that the manhole cover opening device is more stable when in use and avoids slipping.

[0044] By way of example, the moving element 42 is implemented as a wheel.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
