A plurality of third gears are provided on the annular fixing plate. The plurality of third gears and the plurality of first gears are connected together by a chain. A first rotary motor is connected to two of the third gears. A plurality of rollers are arranged circumferentially along the outer edge of the annular fixing plate.

[0007] The construction platform is located below the annular fixing plate.

[0008] Preferably, the construction platform and the annular fixing plate are connected by multiple support rods, and the support rods are arranged close to the inner wall of the annular fixing plate.

[0009] Preferably, a connecting rod is hinged to the support rod, a second rubber block is provided at the end of the connecting rod, and the length of the connecting rod is greater than the distance between the support rod and the well wall. A first slide rail is provided on the connecting rod.

[0010] The support rod is equipped with a telescopic cylinder, which is inclined and the output shaft of the telescopic cylinder is hinged to a first slider, which is slidably connected to the first slide rail.

[0011] Preferably, the annular fixing plate is provided with multiple support platforms, each of which is corresponding to a multiple right-angled triangle. The support platforms are provided with second slide rails, and the lower surface of the right-angled triangles is provided with second sliders. The second sliders are slidably connected to the second slide rails in a corresponding manner.

[0012] Preferably, the support platform is further provided with a third slide rail, and the fixed rod is provided with a third slider, the third slider being slidably connected to the third slide rail in a one-to-one correspondence.

[0013] Preferably, the hypotenuse of the right-angled triangle is provided with a fourth slide rail, and the end of the fixed rod is provided with a fourth slider, the fourth slider being slidably connected to the fourth slide rail.

[0014] Preferably, the construction platform is provided with a pair of annular slides, and the support rod is located inside the annular slides;

[0015] A movable support plate is movably mounted on a pair of annular slide rails. The movable support plate is provided with a pair of fifth slide rails, which are arranged radially along the construction platform.

[0016] The drilling and grouting integrated equipment has two fifth sliders at its bottom, which are slidably connected to two fifth slide rails in a one-to-one correspondence. The movable support plate is equipped with a telescopic motor, and the output shaft of the telescopic motor is connected to the drilling and grouting integrated equipment to drive the drilling and grouting integrated equipment to move along the fifth slide rails.

[0017] Preferably, it also includes:

[0018] Two sets of pipeline adjustment assemblies, each set of pipeline adjustment assemblies includes a first bracket, a spring disposed on the first bracket, a positioning plate disposed at the end of the spring, and a fixed pulley disposed on the positioning plate, wherein the outer edge of the fixed pulley is recessed to form an annular groove to accommodate the pipeline;

[0021] The present invention has at least the following beneficial effects:

[0022] First, the present invention improves the stability of the construction platform by fixing the annular fixing plate through a fixing mechanism. The present invention drives the rotation of the second gear by setting a first gear, a third gear, and a chain. The rotation of the second gear drives the right-angled triangle plate to move. The movement of the right-angled triangle plate drives the fixing rod to move radially along the annular fixing plate, so that the first rubber block moves toward or away from the shaft wall. Thus, the annular fixing plate can be moved up and down while being fixed by the first rubber block.

[0023] Secondly, by setting up a connecting rod, a telescopic cylinder, and a second rubber block, the present invention can not only further fix the annular fixing plate, but also ensure that the second rubber block abuts against the shaft wall before the first rubber block, thus avoiding the first telescopic motor from affecting the stability of the annular fixing plate during rotation.

[0024] Third, the present invention adjusts the length of the pipeline by setting a pipeline adjustment component, reducing pipeline accumulation or knots that affect normal use; by setting two springs, not only can the pipeline length be sufficient to support the movement of the drilling and grouting integrated equipment, but also, when drilling and grouting are completed, the two springs can retract the pipeline during the return movement, avoiding pipeline entanglement and facilitating the smooth progress of drilling and grouting work.

[0025] Fourth, by setting up a fixed frame, a first rod, a hollow second rod, and threaded holes, this invention effectively adjusts the distance between the wheel and the central axis of the annular fixed plate, making the vertical shaft grouting construction platform suitable for vertical shafts of different diameters and expanding the application range of the construction platform; this invention also achieves automatic grouting by setting up an annular slide, a movable support plate, a fifth slide rail, and a fifth slider, reducing the number of workers operating on the construction platform and improving the construction safety of the vertical shaft grouting construction platform.

[0026] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0032] like Figure 1-2 As shown, the present invention provides a vertical shaft grouting construction platform, comprising:

[0033] A fixing mechanism includes an annular fixing plate 1 and a plurality of first gears 2 spaced apart on the annular fixing plate 1. The plurality of first gears 2 are spaced apart circumferentially along the central axis of the annular fixing plate 1. A second gear 3 is provided on the first gear 2. A plurality of right-angled triangles 6 are slidably provided on the annular fixing plate 1. The plurality of right-angled triangles 6 are arranged one-to-one with the plurality of second gears 3. A fixing rod 10 is slidably connected to the hypotenuse of the right-angled triangles 6. A first rubber block 11 is provided at the end of the fixing rod 10. A plurality of meshing teeth 7 are spaced apart along the length of one right-angled side of the right-angled triangles 6. The meshing teeth 7 mesh with the second gears 3. A plurality of third gears 4 are provided on the annular fixing plate 1. The plurality of third gears 4 and the plurality of first gears 2 are connected by a chain 5. A first rotary motor is connected to two of the third gears 4. A plurality of rollers 12 are provided circumferentially along the outer edge of the annular fixing plate 1.

[0034] Construction platform 33 is located below the annular fixing plate 1.

[0035] In this technical solution, the annular fixing plate 1 is horizontally arranged, and multiple first gears 2 are equally spaced circumferentially along the central axis of the annular fixing plate 1. Both the first gears 2 and second gears 3 are horizontally arranged. The first gears 2 are rotatably connected to the annular fixing plate 1, and the first gears 2 and second gears 3 are fixedly connected. A fixing rod 10 is radially arranged along the annular fixing plate 1 and slidably connected to it. Third gears 4 are located on the same horizontal plane as the first gears 2, and multiple third gears 4 are spaced circumferentially along the central axis of the annular fixing plate 1. The chain 5 is annular, and two second supports are provided on the annular fixing plate 1. 13. Two first rotary motors are respectively mounted on two second supports 13. The two first rotary motors are symmetrically arranged along the central axis of the annular fixed plate to simultaneously drive multiple first gears 2 to rotate via chains. Multiple rollers 12 are equally spaced. The annular fixed plate 1 is equipped with multiple hooks, which are connected to multiple winches to drive the annular fixed plate 1 to move up and down along the shaft via the winches. The first rotary motors are reversible motors. Specifically, workers can stand on the construction platform 33 to perform drilling and grouting. The right-angled triangle 6 slides back and forth along the tangent direction of its corresponding second gear. The right-angled triangle 6 slides against the annular fixed plate 1. One specific implementation of the dynamic connection is as follows: the lower surface of the right-angled triangle 6 is provided with a guide block, and the annular fixing plate 1 is provided with a guide groove. The guide groove is arranged radially along the corresponding second gear. The guide block and the guide groove are slidably connected so that the right-angled triangle 6 can move back and forth under the drive of the second gear 3. Another specific implementation of the sliding connection between the fixing rod 10 and the annular fixing plate 1 is as follows: the annular fixing plate 1 is provided with a limiting block, the limiting block is provided with a limiting hole, the central axis of the limiting hole is arranged radially along the annular fixing plate 1, and the diameter of the limiting hole is slightly larger than the diameter of the fixing rod 10. Rod 10 passes through the limiting hole to achieve radial reciprocating movement of the fixed rod 10 along the annular fixed plate 1; in this application, in order to reduce the number of first rotary motors used on the annular fixed plate 1 (the greater the number of first rotary motors used, the higher the probability of failure, and the failure of one first rotary motor will affect the operation of the other first rotary motors), a chain is set to enable two first rotary motors to drive multiple first gears 2 to rotate simultaneously. However, due to position limitations, it is not convenient to directly set the drive motor on the second gear 3. Therefore, this application introduces a third gear 4 to facilitate the setting of the first rotary motors and the limitation of the position of multiple chains.

[0036] During use, when placed inside the shaft, the first rubber block 11 is positioned above the annular fixing plate 1, and the roller 12 contacts the inner wall of the shaft. The annular fixing plate 1 is driven downward by a winch. When it reaches the predetermined position, the first rotary motor is started. The first rotary motor drives the third gear 4 and the first gear 2 to rotate. The first gear 2 drives the second gear 3 to rotate. The second gear 3 drives the right-angled triangle plate 6 to move. The right-angled triangle plate 6 drives the fixing rod 10 to move towards the shaft wall until the first rubber block 11 abuts against the shaft wall. When it is necessary to move the annular fixing plate 1 upward, the first rotary motor rotates in the opposite direction, driving the first rubber block 11 to move towards the annular fixing plate 1. At this time, the annular fixing plate 1 can be moved upward by the winch, and the construction platform 33 is parallel to the annular fixing plate 1.

[0037] By adopting this technical solution, the present invention achieves the fixation of the annular fixing plate 1 by setting a fixing mechanism, thereby improving the stability of the construction platform 33. The present invention achieves the rotation of the second gear 3 by setting the first gear 2, the third gear 4, and the chain 5, and drives the right-angled triangle plate 6 to move through the rotation of the second gear 3. The movement of the right-angled triangle plate 6 drives the fixing rod 10 to move radially along the annular fixing plate 1, thereby enabling the first rubber block 11 to move toward or away from the vertical shaft wall. Thus, while satisfying the requirement that the annular fixing plate 1 can move up and down, the annular fixing plate 1 can also be fixed by the first rubber block 11.

[0038] In another technical solution, the construction platform 33 and the annular fixing plate 1 are connected by multiple support rods 14 (the support rods 14 are vertically arranged), and the support rods 14 are arranged close to the inner sidewall of the annular fixing plate 1. Using this technical solution, the present invention achieves the connection between the construction platform 33 and the annular fixing plate 1 by setting support rods 14.

[0039] In another technical solution, a connecting rod 15 is hinged to the support rod 14, and a second rubber block 16 is provided at the end of the connecting rod 15. The length of the connecting rod 15 is greater than the distance between the support rod 14 and the well wall (that is, when the first rubber block 11 is not in contact with the vertical well wall, the connecting rod 15 is in an inclined state). A first slide rail 18 is provided on the connecting rod 15, and the first slide rail 18 is arranged along the length direction of the connecting rod 15.

[0040] The support rod 14 is equipped with a telescopic cylinder 17, which is inclined and has a first slider 19 hinged to the end of its output shaft. The first slider 19 is slidably connected to the first slide rail 18. During use, when the construction platform 33 reaches the predetermined position, the telescopic cylinder 17 first activates the second rubber block 16 to move upward until it abuts against the shaft wall, and then the first telescopic motor is activated to make the first rubber block 11 abut against the shaft wall. By adopting this technical solution, the present invention, through the setting of the connecting rod 15, the telescopic cylinder 17, and the second rubber block 16, can not only further fix the annular fixing plate 1, but also ensure that the second rubber block 16 abuts against the shaft wall before the first rubber block 11, thus avoiding the first telescopic motor from affecting the stability of the annular fixing plate 1 during rotation.

[0041] In another technical solution, the annular fixing plate 1 is provided with multiple support platforms 20, each corresponding to a multiple right-angled triangular plates 6. Each support platform 20 is provided with a second slide rail 25, and the lower surface of each right-angled triangular plate 6 is provided with a second slider 26. The second slider 26 is slidably connected to the second slide rail 25. This technical solution achieves a slidable connection between the right-angled triangular plates 6 and the annular fixing plate 1.

[0042] In another technical solution, the support platform 20 is further provided with a third slide rail 21, and the fixing rod 10 is provided with a third slider 22, the third slider 22 and the third slide rail 21 being slidably connected in a one-to-one correspondence. This technical solution achieves a slidable connection between the fixing rod 10 and the annular fixing plate 1.

[0043] In another technical solution, the hypotenuse of the right-angled triangle 6 is provided with a fourth slide rail 8, and the end of the fixing rod 10 is provided with a fourth slider 9, which is slidably connected to the fourth slide rail 8. This technical solution achieves a slidable connection between the fixing rod 10 and the right-angled triangle 6.

[0044] In another technical solution, the construction platform 33 is provided with a pair of annular slides 27 (the annular track is coaxially arranged with the construction platform 33), and the support rod 14 is located inside the annular slides 27;

[0045] A movable support plate 29 is movably mounted on a pair of annular slide rails 27. The movable support plate 29 is provided with a pair of fifth slide rails 30 (the fifth slide rails 30 are arranged radially along the construction platform 33). The fifth slide rails 30 are arranged radially along the construction platform 33. The movable support plate 29 includes two pairs of pressing wheels 28, each pair of pressing wheels 28 corresponding to an annular slide rail 27. The movable support plate 29 can be pushed by a person or a third bracket can be provided on the movable support plate 29. The third bracket is provided with a second rotary motor. The second rotary motor is connected to one of the pressing wheels 28 to drive the movable support plate 29 to move. The second rotary motor is a forward and reverse rotating motor.

[0046] The drilling and grouting integrated device 32 (using existing technology) has two fifth sliders 31 at its bottom, which are slidably connected to two fifth slide rails 30. A telescopic motor is mounted on the movable support plate 29, and the output shaft of the telescopic motor is connected to the drilling and grouting integrated device 32 to drive it to move along the fifth slide rails 30. Using this technical solution, the present invention achieves automatic grouting by setting up an annular slide rail 27, a movable support plate 29, fifth slide rails 30, and fifth sliders 31, reducing the need for workers to operate on the construction platform 33 and improving the construction safety of the vertical shaft grouting construction platform.

[0047] In another technical solution, such as Figure 3 As shown, it also includes:

[0048] Two sets of pipeline adjustment assemblies 34 (the pipelines include a grouting pipe connected to the drilling and grouting integrated equipment 32, an electric wire for supplying power to the drilling and grouting integrated equipment 32, and a power supply wire for the telescopic motor). Each set of pipeline adjustment assemblies 34 includes a first bracket 340, a spring 341 (the spring 341 is vertically arranged) on the first bracket 340, a positioning plate 342 at the end of the spring 341, and a fixed pulley 343 on the positioning plate 342. The outer edge of the fixed pulley 343 is recessed to form an annular groove to accommodate the pipeline.

[0049] In this invention, the first support 340 of one set of pipeline adjustment components 34 is connected to the construction platform 33, and the first support 340 of the other set of pipeline adjustment components 34 is connected to the annular fixing plate 1. When the drilling and grouting integrated equipment 32 stops working, both springs 341 are in a naturally extended state. When the drilling and grouting integrated equipment 32 moves along the annular slide 27, the springs 341 on the construction platform contract upward under the squeezing action of the pipeline, and the springs 341 on the annular fixing plate 1 contract downward to satisfy the movement of the drilling and grouting integrated equipment 32. By adopting this technical solution, the present invention achieves pipeline length adjustment by setting the pipeline adjustment components 34, reducing pipeline accumulation or knots that affect normal use; by setting two springs 341, not only can the pipeline length be sufficient to support the movement of the drilling and grouting integrated equipment 32, but also, during the return movement after drilling and grouting, the two springs 341 can retract the pipeline, avoiding pipeline entanglement and facilitating the smooth progress of drilling and grouting work.

[0050] In another technical solution, such as Figure 4 As shown, the roller 12 includes a wheel, a fixing frame 35 connected to the wheel, a first rod 36 connected to the fixing frame 35, and a hollow second rod 37 connected to the annular fixing plate 1. The second rod 37 is inserted into the first rod 36 and has two threaded holes with bolts inside. When the first rod 36 is located inside the second rod 37, the first rod 36 and the second rod 37 are fixed together by the bolts. Using this technical solution, the present invention effectively adjusts the distance between the wheel and the central axis of the annular fixing plate 1 by setting the fixing frame 35, the first rod 36, the hollow second rod 37, and the threaded holes, making the vertical shaft grouting construction platform suitable for vertical shafts of different diameters and expanding the application range of the construction platform.

[0051] The number of devices and processing capacity described herein are for simplification of the invention. Applications, modifications, and variations of the vertical shaft grouting construction platform of this invention will be readily apparent to those skilled in the art.

[0052] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
