Description

Technical Field

[0001] This application relates to the field of manhole cover technology, and particularly to a cable well cover system. Background Art

[0002] Cable manhole covers are used to cover cable wells on roads to prevent people or objects from falling. They can be classified into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to their materials.

[0003] Currently, existing well covers are usually fixed using a fixed frame. When assembling the well cover, the protruding connecting rod on the male plate is snapped onto the female plate, and then tightened with bolts to fix the male plate and the female plate, thereby fixing the adjacent covers that make up the manhole cover correspondingly. However, this fixing method of the manhole cover uses bolt connection. After being run over by vehicles for a long time, it is easy for the well covers to become loose. When a vehicle passes over the well cover, there is likely to be a large noise between the well covers. Utility Model Content

[0004] In order to improve the problem that there is likely to be a large noise between the manhole covers when a vehicle passes by, this application provides a cable well cover system.

[0005] A cable well cover system provided by this application adopts the following technical solution:

[0006] A cable well cover system includes covers, a damping mechanism, and a hatch cover. A plurality of the covers are arranged and embedded at the cable well opening. There is a gap between the plurality of covers and one side of the cable well opening along the arrangement direction of the covers to form a damping chamber. The damping mechanism is arranged on the cable well opening and is connected to the cover close to the damping chamber. The damping mechanism is used to absorb the vibration energy of the cover. The hatch cover is arranged on the cable well opening and is used to close the damping chamber.

[0007] By adopting the above technical solution, construction workers arrange and embed a plurality of covers at the cable well opening in sequence, so that there is a gap between the plurality of covers and one side of the cable well opening along the arrangement direction of the covers, thereby forming a damping chamber for installing the damping mechanism and for the cover to move. Then, the damping mechanism is installed on the cable well opening and the damping mechanism is made to abut against the cover. Finally, the hatch cover is installed on the cable well opening so that the hatch cover closes the damping chamber, thereby covering the cable well opening and improving the dust and water protection ability of the cable well opening. When a vehicle passes by later, the damping mechanism absorbs the vibration energy after the cover is pressed, reducing the possibility of the cover becoming loose on the cable well opening, reducing the vibration of the cover, and effectively improving the problem that there is likely to be a large noise between the manhole covers when a vehicle passes by.

[0008] Optionally, the damping mechanism includes a support, a connecting pin, a damping unit, and a locking member. The support is disposed on the cable wellhead. The connecting pin is slidably inserted into the support. The damping unit is disposed on the connecting pin and abuts against the cover plate. The locking member is disposed on the connecting pin and is used to position the connecting pin on the support.

[0009] By adopting the above technical solution, the construction worker slides the connecting pin on the support in the direction close to the cover plate, so that the connecting pin drives the damping unit to abut tightly against the cover plate, and then positions the connecting pin on the support through the locking member, and the installation or adjustment of the damping unit can be conveniently completed.

[0010] Optionally, the locking member includes locking nuts. Two locking nuts are threadedly arranged on the connecting pin, and the two locking nuts respectively abut against both sides of the support.

[0011] By adopting the above technical solution, the construction worker rotates the two nuts so that the two nuts approach each other and abut against both sides of the support, and the connecting pin can be positioned on the support.

[0012] Optionally, a jack is formed in the cover plate. The connecting pin slidably penetrates through the damping unit and is slidably inserted into the jack. A pressing member for driving the damping unit to abut tightly against the cover plate is disposed on the connecting pin.

[0013] By adopting the above technical solution, the construction worker passes the connecting pin through the damping unit and then slidably inserts it into the jack, and then presses the damping unit tightly against the cover plate through the pressing member. The jack positions the connecting pin, improves the stability of the connecting pin, and further improves the stability of the damping unit.

[0014] Optionally, the pressing member includes a handle. The handle is disposed on the connecting pin and abuts against the damping unit.

[0015] By adopting the above technical solution, the construction worker can conveniently move or rotate the connecting pin through the handle. At the same time, when the connecting pin is driven by the handle to move towards the cover plate, the handle can also press the damping unit tightly against the cover plate.

[0016] Optionally, a first rubber pad is disposed on the cover plate. Adjacent cover plates abut against the first rubber pad.

[0017] By adopting the above technical solution, the first rubber pad enhances the sealing performance between adjacent cover plates, and can provide buffering for adjacent cover plates, reducing the possibility of large noises between adjacent cover plates.

[0018] Optionally, a second rubber pad is disposed between the cover plate and the cable wellhead.

[0019] By adopting the above technical solution, the second rubber pad provides buffering between the cover plate and the cable well opening, enhances the sealing performance between the cover plate and the cable well opening, and reduces the possibility of a large noise occurring between the cover plate and the cable well opening.

[0020] Optionally, positioning holes are formed in the cover plate, and positioning columns for inserting into the positioning holes are arranged on the adjacent cover plates.

[0021] By adopting the above technical solution, when installing adjacent cover plates, the positioning columns are inserted into the positioning holes to position the installation of the adjacent cover plates and improve the stability between the adjacent cover plates.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Reduce the possibility of the cover plate loosening on the cable well opening, reduce the vibration of the cover plate, and effectively improve the problem that a large noise is likely to occur between the manhole covers when a vehicle passes by;

[0024] 2. The connecting pin drives the damping unit to abut against the cover plate, and then the connecting pin is positioned on the support by the locking member, so that the installation or adjustment of the damping unit can be conveniently completed;

[0025] 3. The first rubber pad enhances the sealing performance between adjacent cover plates, and can provide buffering for adjacent cover plates, reducing the possibility of a large noise occurring between adjacent cover plates. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present application in detail with reference to the accompanying drawings. Figures 1-5

[0033] Embodiment 1

[0034] The embodiment of the present application discloses a cable well cover system.

[0035] Referring to Figure 1 and Figure 2 , the cable well cover system includes a cover plate 1, a damping mechanism 2, a bin cover 3, a pressing member 5, a first rubber pad 6, a second rubber pad 7, and a positioning post 8.

[0036] Referring to Figure 1 and Figure 2 , a plurality of cover plates 1 are arranged and embedded at the cable well opening. There is a gap between the plurality of cover plates 1 and one side of the cable well opening along the arrangement direction of the cover plates 1 to form a damping bin 4. The damping bin 4 is used to provide a moving space for the cover plates 1 and an installation space for the damping mechanism 2. The bin cover 3 is installed on the cable well opening, and the bin cover 3 is used to close the damping bin 4. Thus, the opening of the cable well cover can be covered by the bin cover 3 and the plurality of cover plates 1.

[0037] Referring to Figure 2 , a positioning post 8 is installed on one side of the cover plate 1, and a positioning hole is formed on the other side of the cover plate 1 for the positioning post 8 to insert. When construction workers install adjacent cover plates 1, the positioning post 8 is inserted into the positioning hole. The side wall of the positioning hole guides and limits the positioning post 8, thereby positioning the installation of adjacent cover plates 1 and improving the stability between adjacent cover plates 1.

[0038] Referring to Figure 2 , a first rubber pad 6 is installed on the side of the cover plate 1, and adjacent cover plates 1 are pressed against the first rubber pad 6. In this embodiment, the first rubber pad 6 includes a high-elastic water-stop rubber pad and a pressure-resistant and wear-resistant rubber pad. The high-elastic water-stop rubber pad is circumferentially installed on the side of the cover plate 1, and the pressure-resistant and wear-resistant rubber pad is installed in the middle of the side of the cover plate 1. Adjacent cover plates 1 are pressed against the high-elastic water-stop rubber pad and the pressure-resistant and wear-resistant rubber pad. The high-elastic water-stop rubber pad enhances the tightness between adjacent cover plates 1, improves the waterproof and dust-proof performance between adjacent cover plates 1, and the high-elastic water-stop rubber pad and the pressure-resistant and wear-resistant rubber pad can also provide buffering between adjacent cover plates 1, reducing the possibility of a large noise occurring between adjacent cover plates 1 when a vehicle passes by.

[0039] Referring to Figure 2 ​, a second rubber pad 7 is installed between the cover plate 1 and the cable wellhead. In this embodiment, the second rubber pad 7 also includes a high-elastic water-stop rubber pad and a pressure-resistant and wear-resistant rubber pad. The high-elastic water-stop rubber pad is circumferentially installed on the bottom wall of the cable wellhead, and the pressure-resistant and wear-resistant rubber pad is circumferentially installed on the side wall of the cable wellhead. When installing the cover plate 1, the cover plate 1 abuts against the high-elastic water-stop rubber pad and the pressure-resistant and wear-resistant rubber pad. The high-elastic water-stop rubber pad enhances the tightness between the cover plate 1 and the bottom wall of the cable wellhead, improves the waterproof performance between the cover plate 1 and the cable wellhead, and the high-elastic water-stop rubber pad and the pressure-resistant and wear-resistant rubber pad can also provide buffering between the cover plate 1 and the cable wellhead. When a vehicle passes by, it reduces the possibility of a large noise between the cover plate 1 and the cable wellhead.

[0040] Refer to Figure 2 , Figure 3 , the damping mechanism 2 is installed on the side wall of the cable wellhead away from the cover plate 1. The damping mechanism 2 abuts against the cover plate 1 on the side close to the damping chamber 4. The damping mechanism 2 is used to absorb the vibration energy of the cover plate 1. The damping mechanism 2 includes a support 21, a connecting pin 22, a damping unit 23 and a locking member 24. The support 21 is installed on the cable wellhead. An installation groove is vertically opened on the support 21. A jack is opened on one side of the cover plate 1 close to the damping chamber 4. The connecting pin 22 slides through the installation groove and extends to slide through the jack. The jack positions the connecting pin 22 and improves the stability of the connecting pin 22.

[0041] The locking member 24 is installed on the connecting pin 22. The locking member 24 is used to lock the connecting pin 22 on the support 21. The locking member 24 includes two locking nuts 241. One end of the connecting pin 22 close to the support 21 is threaded. Both locking nuts 241 are threadedly installed on the connecting pin 22.

[0042] The construction worker first screws one of the locking nuts 241 onto the connecting pin 22, then snaps the connecting pin 22 into the installation groove from the opening of the installation groove, and then screws the other locking nut 241 onto the connecting pin 22 so that the two locking nuts 241 are respectively located on both sides of the support 21. Tighten the two locking nuts 241 to move closer to each other, and the two locking nuts 241 can abut against both sides of the support 21, thereby conveniently and quickly positioning the connecting pin 22 on the support 21. And by adjusting the positions of the two locking nuts 241 on the connecting pin 22, the positioning position of the connecting pin 22 on the support 21 can also be adjusted, and then the distance between the connecting pin 22 and the cover plate 1 can be adjusted.

[0043] Refer to Figure 2 , Figure 3, the shock-absorbing unit 23 is installed on the connecting pin 22, and the shock-absorbing unit 23 abuts against the cover plate 1. In this embodiment, the shock-absorbing unit 23 includes a mounting plate, a shock-absorbing rubber pad, and a shock-absorbing spring. One mounting plate is installed on each side of the shock-absorbing spring. The shock-absorbing rubber pad is installed on the side of the mounting plate away from the shock-absorbing spring. The connecting pin 22 slidably passes through the mounting plate and through the shock-absorbing spring. In other embodiments, a hydraulic shock absorber, a pneumatic shock absorber, etc. can also be used; a pressing member 5 is installed on the connecting pin 22, and the pressing member 5 is used to drive the shock-absorbing unit 23 to abut against the cover plate 1. The pressing member 5 includes a handle 51, and the handle 51 is installed on the connecting pin 22 and used to abut against the shock-absorbing unit 23. The construction worker holds the handle 51, and can adjust the position of the connecting pin 22 and drive the connecting pin 22 to rotate, improving the convenience for the construction worker to control the connecting pin 22. When the handle 51 abuts against the shock-absorbing rubber pad and thus presses the shock-absorbing rubber pad on the other side against the cover plate 1, when the vehicle passes by and causes the cover plate 1 to vibrate, the vibration energy can be transmitted to the shock-absorbing spring and the shock-absorbing rubber pad. The shock-absorbing spring and the shock-absorbing rubber pad act together to absorb the shock energy, and by pressing against the cover plate 1, the fitting degree of the sealing surface between the cover plates 1 can be enhanced, and the tightness between the cover plates 1 can be improved.

[0044] The implementation principle of Embodiment 1 of this application is as follows: The construction worker sequentially arranges and installs multiple cover plates 1 adjacent to each other on the cable wellhead, so that a gap is left on one side of the multiple cover plates 1 along the arrangement direction of the cover plates 1 to form a shock-absorbing chamber 4. Then, the connecting pin 22 is passed through the shock-absorbing unit 23, and then the connecting pin 22 is installed on the support 21, so that the connecting pin 22 is inserted into the jack on the cover plate 1. Then, the position of the connecting pin 22 is adjusted so that the handle 51 on the connecting pin 22 presses the shock-absorbing unit 23 against the cover plate 1. Then, the connecting pin 22 is locked on the support 21 through two lock nuts, and the installation of the shock-absorbing mechanism 2 can be completed. Finally, the hatch cover 3 is installed on the cable wellhead to cover the cable wellhead. When the vehicle passes by the cable wellhead, the energy transmitted to the cover plate 1 causes the cover plate 1 to vibrate. The shock-absorbing mechanism 2 absorbs the vibration energy after the cover plate 1 is pressed, reducing the possibility of the cover plate 1 loosening on the cable wellhead, reducing the vibration of the cover plate 1, and effectively improving the problem that there is often a large noise between the manhole covers when the vehicle passes by.

[0045] Embodiment 2

[0046] Refer to Figure 4, the difference between the embodiment of the present application and Embodiment 1 lies in that: the width of the cover plate 1 far from the shock absorption chamber 4 decreases successively from top to bottom, the diameter of the side wall of the adjacent cover plate 1 in contact with this cover plate 1 increases successively from top to bottom, and the diameter of the side wall at the cable well opening in contact with this cover plate 1 increases successively from top to bottom. When the staff installs the cover plate 1 far from the shock absorption chamber 4, the side wall of this cover plate 1 with a gradually decreasing width from top to bottom squeezes the adjacent cover plate 1, so that the multiple cover plates 1 are closely attached under the squeezing action, improving the tightness between the adjacent cover plates 1, reducing the possibility of sewage and dust entering the cable well opening between the adjacent cover plates 1, and increasing the waterproof and dustproof performance of the cover plate 1 for the cable well opening.

[0047] Embodiment 3

[0048] Refer to Figure 5 , the difference between the embodiment of the present application and Embodiment 1 lies in that: an installation cavity is formed between the side of the cover plate 1 far from the shock absorption chamber 4 and the side wall of the cable well opening. A spring piece 9 is installed in the installation cavity. The spring piece 9 abuts against the cover plate 1. The spring piece 9 always has a tendency to drive this cover plate 1 to move towards the shock absorption chamber 4, so that the cover plate 1 far from the shock absorption chamber 4 always keeps squeezing towards the shock absorption chamber 4, so that the multiple cover plates 1 are kept closely attached, improving the tightness between the adjacent cover plates 1, reducing the possibility of sewage and dust entering the cable well opening between the adjacent cover plates 1, and increasing the waterproof and dustproof performance of the cover plate 1 for the cable well opening.

[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
