[0026] Specific implementation methods

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Embodiment 1

[0029] like Figure 1-2 As shown, this embodiment proposes a municipal road well chamber lifting tool, including a steel plate 1 and an extension plate 2, one end of the extension plate 2 is fixedly connected to one end of the steel plate 1, and the other end of the extension plate 2 is slidably connected to the other end of the steel plate 1, the steel plate 1 and the extension plate 2 cooperate with each other to be wound into a circle or an ellipse, the steel plate 1 and the extension plate 2 both have a certain flexibility and can be bent to a certain extent, so as to better fit with the well chamber and make it easier to adjust the inner diameter.

[0030] A second baffle plate 4 is connected to the inner side of the steel plate 1, a first baffle plate 3 is connected to the inner side of the extension plate 2, a screw rod 5 is threadedly connected to the second baffle plate 4, and one end of the screw rod 5 abuts against the first baffle plate 3 after passing through the second baffle plate 4. By rotating the screw rod 5, the screw rod 5 can push the first baffle plate 3 to move, thereby adjusting the distance between the first baffle plate 3 and the second baffle plate 4.

[0031] The first baffle plate 3 is arranged at the end of the extension plate 2 . The first baffle plate 3 is fixedly connected to the extension plate 2 . The first baffle plate 3 can be fixed to the extension plate 2 by welding, and the first baffle plate 3 is arranged on the inner circle of the extension plate 2 .

[0032] A slide groove is provided in the extension plate 2, the other end of the steel plate 1 is slidably arranged in the slide groove, and the second baffle plate 4 is located outside the slide groove.

[0033] There are two configuration modes for the second baffle plate 4 , one of which is that the second baffle plate 4 is fixedly connected to the steel plate 1 .

[0034] The second type is that the second baffle plate 4 is slidably connected to the steel plate 1, and the second baffle plate 4 is connected to a limit rod 15 that can limit the movement of the second baffle plate 4. When it is a sliding connection, the second baffle plate 4 can be moved first to adjust the distance that the steel plate 1 slides into the extension plate 2. At this time, a larger range of inner diameter adjustment can be achieved, and then the screw rod 5 can be rotated to achieve fine adjustment.

[0035] The limiting rod 15 is threadedly connected to the second baffle plate 4. The steel plate 1 is provided with a plurality of thread grooves into which the limiting rod 15 can be screwed. The limiting rod 15 can be screwed out of the thread groove. At this time, the second baffle plate 4 can slide freely on the steel plate 1. By tightening the limiting rod 15, the limiting rod 15 is screwed into the thread groove. At this time, the relative fixing of the position of the steel plate 1 can be achieved.

[0036] The limiting rod 15 is slidably connected to the second baffle plate 4. The limiting rod 15 is connected to the second baffle plate 4 through a return spring. The steel plate 1 is provided with a plurality of limit holes into which the limiting rod 15 can slide. The return spring is sleeved on the limiting rod 15. One end of the return spring is connected to the limiting rod 15, and the other end of the return spring is connected to the steel plate 1. In the initial state, under the action of the return spring, the limiting rod 15 can slide into the limit hole. By pulling the limiting rod 15 outward, the limiting rod 15 can be separated from the limit hole, and the second baffle plate 4 can slide on the steel plate 1.

[0037] The second baffle plate 4 is provided with a through hole 7 for the screw rod 5 to freely pass through. The second baffle plate 4 is fixedly connected with a nut 6 , and the screw rod 5 and the nut 6 are threadedly connected.

[0038] There are two connection modes between the screw rod 5 and the first baffle plate 3 , one of which is that the screw rod 5 abuts against the first baffle plate 3 , and the other is that the screw rod 5 and the first baffle plate 3 are rotatably connected.

[0039] By rotating the screw rod 5 , the screw rod 5 and the first baffle plate 3 come into contact, and the first baffle plate 3 can be driven to move in a direction away from the second baffle plate 4 , thereby achieving distance adjustment.

[0040] Embodiment 2

[0041] Reference Figure 3-4, other structures are the same as those in the first embodiment, except that the connection problem between the steel plate and the extension plate is taken into consideration in this embodiment.

[0042] The steel plate 1 is connected with a ratchet 9 , the extension plate 2 is provided with a sliding hole 11 , a sliding plate 13 is slidably connected in the sliding hole 11 , a clamping rod 12 matched with the ratchet 9 is fixedly connected to the sliding plate 13 , and a spring 14 is also connected to the sliding plate 13 .

[0043] When the screw 5 rotates to move the first baffle 3 away from the second baffle 4, under the action of the ratchet 1, the clamping rod 12 drives the sliding plate 13 to slide in the sliding hole 11. At this time, the inner diameter of the tool formed by the steel plate 1 and the extension plate 2 becomes larger, and under the limiting action of the clamping rod 12, when the clamping rod 12 and the ratchet 1 are in a mating state, the inner diameter cannot be reduced. Therefore, the tool and the well chamber can be prevented from being separated, thereby improving the overall fixing effect and preventing the inner diameter from being reduced due to the breakage of the screw 5.

[0044] The extension plate 2 is provided with a threaded hole 10, which is connected to the sliding hole 11, and the threaded block 8 is threadedly connected to the threaded hole 10, and the other end of the spring 14 is connected to the threaded block 8. The threaded block 8 is provided with a small groove, which is connected to the sliding hole 11, and the spring 14 is arranged in the small groove, and the other end of the spring 14 is rotatably connected to the threaded block 8.

[0045] By rotating the threaded block 8, the compression degree of the spring 14 can be adjusted, thereby adjusting the resistance when the steel plate 1 and the extension plate 2 slide relative to each other. When the compression degree of the spring 14 is large enough, it is necessary to rotate the screw rod 5 more forcefully to expand the inner diameter, which is conducive to fine adjustment work and facilitates the adjustment of the inner diameter.

[0046] When the limit needs to be released, the threaded block 8 can be rotated outward, and the threaded block 8 can pull the sliding plate 13 outward through the spring 14, so that the clamping rod 12 and the ratchet 9 can be disengaged. At this time, the clamping rod 12 no longer limits the movement of the steel plate 1.

[0047] The inner circles of the steel plate 1 and the extension plate 2 are fixedly connected with a plurality of steel bars, and the steel bars are arranged to facilitate the disassembly of the tool. After the concrete is poured, the tool needs to be disassembled through the steel bars.

[0048] Specific construction process:

[0049] 1. Position and install the well seat: adjust the plane position of the well seat according to the center of the inspection well, adjust the elevation of the well seat according to the road surface, and install the well seat stably in place.

[0050] 2. Install the well chamber lifting tool: adjust the diameter of the well chamber lifting tool to a suitable size for placement, and adjust the horizontal position according to the center of the inspection well. When adjusting the height, pay attention to the overlap between the lower part and the wellbore, and the overlap between the upper part and the well seat.

[0051] 3. Adjust the screw 5 to fit the well seat: according to the inner diameter of the wellbore and the well seat, rotate the screw 5, adjust the extension length of the screw 5 through the nut 6, push the first baffle 3, and adjust the steel plate 1 and the extension plate 2 to fit the inner diameter of the wellbore and the well seat and fit tightly.

[0052] 4. Pouring concrete: lay plastic sheets on the road surface around the manhole cover concrete pouring position to protect the existing road surface. After the concrete is unloaded to the pouring position, it is leveled manually, vibrated with a vibrator, and finally smoothed and polished with a trowel.

[0053] 5. After initial setting, adjust the screw rod 5 to separate from the well seat: After the initial setting of the concrete, rotate the screw rod 5 to shorten the extended length of the screw rod 5 so that the extension plate 2 and the steel plate 1 retract inward and separate from the poured concrete.

[0054] 6. Remove the well chamber lifting tool: Use the preset steel bars to manually pull out the well chamber lifting tool, clean the surface, apply the release agent, and enter the next construction cycle.

[0055] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
