Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a municipal road manhole cover supporting structure. Background Art

[0002] There are some pipeline wells on many roads in urban and rural construction. Most of these pipeline wells are used for sewage, telecommunication cables, water and gas transmission, etc., and manhole covers are installed on the road surface of these pipeline wells, not only to ensure the safe passage of pedestrians and vehicles, but also to allow workers to open the manhole covers for maintenance. In life, we always see in news and other videos or with our own eyes that some manhole covers are missing or crooked, causing pedestrians to accidentally fall and produce some bad effects. This is also because the staff need to enter the pipeline well, resulting in a relatively simple support structure for the manhole cover, which may cause deformation and dislocation under the rolling of large vehicles for a long time. In addition, the traditional manhole cover design will leave holes and other structures on the manhole cover to facilitate its tilting, which may also lead to some bad people to steal or maliciously destroy, which may eventually lead to a tragedy. For this reason, we propose a municipal road manhole cover support structure to solve the above problems. Utility Model Content

[0005] Preferably, a worm wheel is fixedly sleeved on the threaded rod near the upper side, and a worm is meshingly connected to the rear end of the worm wheel, utilizing the transmission and locking characteristics of the worm wheel and worm.

[0006] Preferably, a movable groove is provided at the left end of the well seat near the upper side, and the left end of the worm penetrates and is slidably connected to the inside of the movable groove, thereby ensuring the rationality of the structural design.

[0007] Preferably, the left end of the worm is fixedly connected to a rotating wheel, and an anti-theft box is provided on the outer side of the rotating wheel. The anti-theft box is fixedly connected to the well seat to play an anti-theft role.

[0008] Preferably, the outer periphery of the worm is fixedly sleeved with bearing seats near the left and right ends, and the upper bases of the bearing seats are fixedly connected to the manhole cover body, so that the worm and the manhole cover body can form a whole and maintain synchronization.

[0009] Preferably, the six ends of the six-rod seat are fixedly connected with reinforcing rods near the middle, and the upper ends of the reinforcing rods are in contact with the manhole cover body, further enhancing the supporting effect on the manhole cover body, while facilitating the removal of the six-rod seat from the inside of the manhole seat, making it convenient for workers to enter the inside of the pipeline well.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The outer circle of the manhole cover body is supported by the manhole seat, and the manhole cover body is further supported by the support rod. At the same time, the six ends of the six-rod seat are engaged with the support rod through the slot, thereby restricting the six-rod seat from rotating, and the six-rod seat supports the threaded rod, so that the threaded rod provides support for the middle of the manhole cover body, which is more uniform, greatly improves the support effect and stability of the manhole cover body, and effectively reduces the skewness of the manhole cover body.

[0012] 2. When it is necessary to open the manhole cover body, it is necessary to first open the anti-theft box with a special key, and then rotate the wheel to drive the worm to rotate, so that the threaded rod can finally lift the manhole cover body. After the manhole cover body is moved away, the six-rod seat at the inner bottom of the manhole seat can still play an anti-falling effect, thereby providing better protection for pedestrians. The six-rod seat can be quickly taken out from the inside of the manhole seat through the reinforcing rod, so that the staff can normally enter the inside of the pipeline well to work, ensuring the rationality of this design, thereby achieving the purpose of preventing possible theft and malicious destruction by some bad people, providing ideal safety protection for pedestrians and vehicles, and at the same time, the operation of opening the manhole cover body is simple and convenient, and safer.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a municipal road manhole cover support structure includes a manhole cover body 1 and a manhole seat 2. An adapter seat 3 is fixedly connected to the middle of the lower end of the manhole cover body 1, and a threaded rod 4 is rotatably connected to the lower end of the adapter seat 3. A six-rod seat 7 is placed at the inner bottom of the manhole seat 2. The lower end of the threaded rod 4 is pressed against the middle of the upper end of the six-rod seat 7. The outer side of the threaded rod 4 is threadedly connected with a threaded sleeve 5 near the lower side. The outer periphery of the threaded sleeve 5 is fixedly connected with six groups of evenly distributed limiting rods 6. Six groups of evenly distributed limiting holes 8 are arranged in the middle position of the upper end of the six-rod seat 7. The lower end of the six-rod seat 7 can be detachably inserted into the inside of the limiting hole 8. A clamping groove 9 is arranged in the middle of the six ends of the six-rod seat 7. Six groups of evenly distributed support rods 10 are fixedly connected to the inner bottom of the manhole seat 2 near the edge, and the clamping groove 9 is adapted to the support rod 10.

[0020] A worm wheel 11 is fixedly sleeved on the threaded rod 4 near the upper side, and a worm 12 is meshedly connected to the rear end of the worm wheel 11. The rotation of the worm 12 drives the worm wheel 11 to rotate, and the rotation of the worm wheel 11 can drive the threaded rod 4 to rotate. Since the threaded sleeve 5 is restricted by the limit rod 6 and the limit hole 8, and at the same time, the six ends of the six-rod seat 7 are engaged with the support rod 10 through the card slot 9, the six-rod seat 7 is restricted to prevent it from rotating, so it can move upward when the threaded rod 4 rotates.

[0021] A movable groove 14 is provided at the left end of the well seat 2 near the upper side, and the left end of the worm 12 passes through and is slidably connected inside the movable groove 14. The worm 12 rises synchronously with the well cover body 1 and the threaded rod 4. The design of the movable groove 14 ensures that the worm 12 can rise normally.

[0022] The left end of the worm 12 is fixedly connected to a rotating wheel 13, and an anti-theft box 16 is arranged on the outer side of the rotating wheel 13. The anti-theft box 16 is fixedly connected to the manhole seat 2. When the manhole cover body 1 needs to be opened, the anti-theft box 16 needs to be opened first with a special key, and then the rotating wheel 13 is rotated to drive the worm 12 to rotate, thereby preventing possible theft and malicious damage by some bad people, and providing ideal safety protection for pedestrians and vehicles.

[0023] The outer periphery of the worm 12 is fixedly sleeved with a bearing seat 15 near the left and right ends. The upper base of the bearing seat 15 is fixedly connected to the manhole cover body 1, and the bearing seat 15 provides support and fixation for the worm 12.

[0024] The six ends of the six-rod seat 7 are fixedly connected with a reinforcing rod 17 near the middle, and the upper ends of the reinforcing rods 17 are in contact with the manhole cover body 1. The reinforcing rods 17 can further provide support for the manhole cover body 1. The six-rod seat 7 can also be quickly removed from the inside of the manhole seat 2 through the reinforcing rods 17, so that the staff can normally enter the interior of the pipeline well to perform operations, thereby ensuring the rationality of this design.

[0025] Working principle:

[0026] When in use, the outer ring of the manhole cover body 1 is supported by the manhole seat 2, and then the manhole cover body 1 is further supported by the support rod 10, and the six-rod seat 7 supports the threaded rod 4, so that the threaded rod 4 provides support for the middle of the manhole cover body 1, which is more uniform, greatly improves the support effect and stability of the manhole cover body 1, and effectively reduces the skew of the manhole cover body 1. When the manhole cover body 1 needs to be opened, the anti-theft box 16 needs to be opened first with a special key, and then the rotating wheel 13 is rotated to drive the worm 1 2 rotates, the worm wheel 11 rotates through the rotation of the worm 12, and the threaded rod 4 can be driven to rotate through the rotation of the worm wheel 11. Since the threaded sleeve 5 is restricted by the limiting rod 6 and the limiting hole 8, at the same time, the six ends of the six-rod seat 7 are engaged with the support rod 10 through the card slot 9, thereby restricting the six-rod seat 7 from rotating. Therefore, when the threaded rod 4 rotates, it can move upward, so that the manhole cover body 1 is lifted up by the threaded rod 4. In this process, the worm 12 rises synchronously with the manhole cover body 1 and the threaded rod 4, and moves through the moving slot 1 The design of 4 ensures that the worm 12 can rise normally. After the manhole cover body 1 rises to a certain height and disengages from the manhole seat 2, it is directly moved away. At this time, the threaded sleeve 5 will drive the limiting rod 6 to disengage from the limiting hole 8. It is worth noting that when the structures such as the manhole cover body 1, the threaded rod 4 and the worm 12 are lost or damaged, the six-rod seat 7 at the inner bottom of the manhole seat 2 can still play an anti-falling effect, thereby better providing protection for pedestrians. Furthermore, the reinforcing rod 17 can further provide support for the manhole cover body 1, and the six-rod seat 7 can also be quickly removed from the inside of the manhole seat 2 through the reinforcing rod 17, so that the staff can normally enter the inside of the pipeline well to perform operations, ensuring the rationality of this design, that is, if you want to open the manhole cover body 1, you need to use a special key to open the anti-theft box 16 first, and then perform the above operation to open the manhole cover body 1, which prevents the possible theft and malicious destruction of some bad people, and provides ideal safety protection for pedestrians and vehicles. At the same time, the operation of opening the manhole cover body 1 is simple, convenient and safer.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
