Description

Technical Field

[0001] The present invention relates to the field of inspection wells, and in particular to a drainage pipeline inspection well reinforcement and repair device. Background Art

[0002] As one of the auxiliary facilities of the drainage pipeline, the inspection well plays the role of an inspection hole for the drainage facility. Since the interior of the inspection well is designed to be hollow, it directly bears the pressure of the ground during use, so it is easy to be damaged. In the existing technology, the method for repairing a damaged inspection well is to apply a layer of cement on the surface of the inspection well where damage and leakage occur, or to drill and grout at the crack and leakage to achieve leak plugging, or to install a liner with reinforcing ribs at the damaged part. However, the existing devices are all fixed directly on the inner wall of the inspection well when they are fixed, and the pressure on the inspection well will cause damage to the inspection well to a certain extent. Secondly, when installing the liner, cement needs to be injected between the liner and the inspection well, and temporary support columns are required to temporarily support the liner while waiting for the cement to be filled and solidified. Currently, most of the temporary support is done manually, which is time-consuming and labor-intensive. Summary of the Invention

[0043] Combine Figure 3As shown, support plate 5 is mounted on mounting plate 1. Support plate 5 is an arc-shaped plate that temporarily supports the reinforcement lining. Support plate 5 is rotated by a rotating mechanism. The rotating mechanism includes a motor 6 fixed to the lower end of movable plate 3, and the output shaft of motor 6 is fixed to rotating shaft 9. The cam 14 is provided with a plurality of holes for the upper and lower fixing plates 7 and 8, respectively, and the upper and lower fixing plates 7 and 8 are provided with holes for the rotation shaft 9 to pass through; the upper end of the upper fixing plate 7 and the lower end of the lower fixing plate 8 are respectively provided with an upper limit groove 10 and a lower limit groove 11, and the upper limit plate 12 and the lower limit plate 13 are fixed on the rotation shaft 9 and are respectively located above the upper fixing plate 7 and below the lower fixing plate 8, and the upper limit plate 12 and the lower limit plate 13 are respectively adapted to the upper limit groove 10 and the lower limit groove 11; a support column 14 is provided between the upper fixing plate 7 and the lower fixing plate 8, and the upper and lower ends of the support column 14 are respectively in contact with the upper fixing plate 7 and the lower fixing plate 8; a lower clamping rod 15, the lower clamping rod 15 is fixed to the lower end of the movable plate 3, the upper end of the lower fixing plate 8 and the lower clamping rod A lower card slot 16 is provided below 15, which is adapted to the lower card rod 15, and a cross bar 17 is fixed on the side wall of the lower card rod 15. An upper card rod 18 is fixed to the upper end of the lower card rod 15, and the upper card rod 18 is located below the upper fixed plate 7. An upper card slot 19 is provided at the lower end of the upper fixed plate 7 and above the upper card rod 18, and the upper card slot 19 is adapted to the upper card rod 18; a lower support plate 21, which is provided at the lower end of the lower fixed plate 8, and the lower support plate 21 is fixed to the mounting plate 1 by a connecting rod 20.

[0044] The rotating mechanism can drive the upper fixed plate 7 and the lower fixed plate 8 to rotate, specifically as follows: if the upper fixed plate 7 needs to rotate but the lower fixed plate 8 does not rotate, the cylinder 4 is started, and the cylinder 4 drives the movable plate 3 and the rotating shaft 9 to move downward, so that the upper limit plate 12 extends into the upper limit slot 10, and the lower limit plate 13 leaves the lower limit slot 11 and enters the rotation slot 22; at the same time, the upper clamping rod 18 moves downward and leaves the upper clamping slot 19, and the lower clamping rod 15 moves downward and extends into the lower clamping slot 16, that is, the lower clamping rod 15 can limit the rotation of the lower fixed plate 8.

When the lower fixed plate 8 needs to be rotated and the upper fixed plate 7 does not move, the cylinder 4 is started, so that the cylinder 4 drives the movable plate 3 and the rotating shaft 9 to move upward, so that the upper limit plate 12 leaves the upper limit slot 10 and the lower limit plate 13 enters the lower limit slot 11; at the same time, the cylinder 4 drives the lower clamping rod 15 and the upper clamping rod 18 to move upward, the lower clamping rod 15 leaves the lower clamping slot 16, and the upper clamping rod 18 extends into the upper clamping slot 19, that is, the upper clamping rod 18 restricts the upper fixed plate 7 from rotating, and the motor 6 is started. The motor 6 drives the lower fixed plate 8 to rotate through the lower limit plate 13, while the upper fixed plate 7 does not rotate.

[0045] A spray gun 24 is also fixed to the lower end of the rotating shaft 9. The spray gun 24 is connected to the spray liquid delivery device through a connecting pipe 25. The spray gun 24 can be driven by the motor 6 to rotate and perform preliminary repairs on the damaged inner wall of the inspection well 26. The spray liquid delivery device may include a liquid storage tank and a delivery pump to facilitate the spraying of the spray liquid.

[0046] See also Figure 1 As shown, a drainage pipe inspection well reinforcement and repair device also includes a telescopic mechanism 40, which is respectively fixed on both sides of the mounting plate 1. The telescopic mechanism 40 extends out of the inspection well 26. The telescopic mechanism 40 can be an electric telescopic rod, or it can be any telescopic mechanism 40 that can be telescoped in the vertical direction in the prior art; a fixing mechanism, which is fixed to the upper end of the telescopic mechanism 40, and the fixing mechanism is used to stabilize the device on the ground.

[0047] Combine Figure 4 As shown, the fixing mechanism includes a mounting frame 27; a moving block 28, which is mounted on the mounting frame 27 and can move along the mounting frame 27; and a pressing box 29, which is positioned below the moving block 28 and has an adjustable distance therebetween. Furthermore, the mounting frame 27 is an annular mounting frame 27, and the moving block 28 is sleeved on the mounting frame 27. The moving block 28 and the mounting frame 27 are fixed together by bolts 30. The fixing mechanism also includes a screw 31, which passes through the moving block 28 and is threadedly connected to the moving block 28. A handle 32 is fixed to the upper end of the screw 31, and the lower end of the screw 31 is fixed to the pressing box 29.

[0048] like Figure 5 As shown, a partition 33 is fixed horizontally in the press box 29. Gravel 34 is filled in the press box 29 and below the partition 33. A plurality of pressing blocks 35 are evenly distributed in the press box 29. The upper ends of the pressing blocks 35 are fixed to movable rods 36. The upper ends of the movable rods 36 extend through the partition 33 to the top of the partition 33 and are fixed to the stoppers 37. The lower end plate 39 of the press box 29 is plugged into the press box 29. An elastic band 38 is fixed to the lower end opening of the press box 29. The elastic band 38 seals the lower end opening of the press box 29. Slide rails are provided at both ends of the lower end plate 39 of the press box 29. The inner wall of the lower end opening of the press box 29 is provided with a slide groove that matches the slide rails.

[0049] Working Principle: First, secure the fixing mechanism to the ground outside the manhole. Move the movable block 28 along the mounting frame 27 to move the pressure box 29 to a suitable position on the ground. Then, secure the movable block 28 to the mounting frame 27. Turn the handle 32, which in turn rotates the screw 31, adjusting the distance between the pressure box 29 and the movable block 28 as needed. After the pressure box 29 is in place, remove the lower end plate 39. If there is a depression in the ground, the pressure block 35 descends under the action of gravity, driving the elastic band 38 downward. Gravel 34 then fills the depression, further stabilizing the pressure box 29. A gravity block can be placed on the upper end of the pressure box 29 to further stabilize the device.

[0050] According to the depth of the inspection well 26, the length of the telescopic mechanism 40 is adjusted to allow the mounting plate 1 to move within the inspection well 26. When it moves to the damaged part of the well wall, it stops moving and uses the motor 6 to aim the spray gun 24 at the damaged part, and the damaged part is sprayed with the spray gun 24. After the spraying is completed, the motor 6 is reset. A lining plate with ribs is installed at the damaged part, and then the electric telescopic rod 23 is started to make the two support plates 5 close to the inner wall of the lining plate, that is, the support plates 5 provide temporary support for the lining plate. Cement is filled between the lining plate and the inspection well 26 and waited for the cement to solidify. At regular intervals, in order to ensure that the support plate 5 exerts a certain pressure on different parts of the inner wall of the lining plate and to prevent the upper fixed plate 7 and the lower fixed plate 8 from rotating at the same time and causing the lining plate to fall, the rotating mechanism is used to rotate the upper fixed plate 7 alone or the lower fixed plate 8 alone by a certain angle. After the cement solidifies, the device is removed.
