Description

Technical Field

[0001] This application relates to the technical field of lightweight soil processing equipment, and in particular to a lightweight soil pouring equipment and its construction method. Background Technology

[0002] Initially, cast-in-place foamed lightweight soil was mainly used in building roof and ground energy-saving insulation projects. However, as other fields have gradually increased their awareness of the excellent properties of this material, its application scope is rapidly expanding. Its application in municipal road and bridge subgrades, underground structures, port water conservancy, mine backfilling and other projects is increasing year by year. Construction units are also raising their requirements for cast-in-place foamed lightweight soil equipment used for road and bridge subgrade backfilling.

[0003] Traditional foamed lightweight soil workstations typically prepare foam from a foaming agent aqueous solution, mix it with essential components such as cement-based cementitious materials, water, and optional components such as aggregates, admixtures, and additives in a certain proportion, and then fill it into the desired area to harden it into a lightweight material. This is generally used for backfilling in large-scale projects (such as highways and land reclamation). Fully automated foamed lightweight soil workstations or lightweight concrete workstations are efficient options. In existing technologies, to ensure the quality of lightweight soil, integrated lightweight soil pouring machines are often used.

[0004] For example, Chinese patent document CN214773057U discloses a foamed lightweight soil working station, including a box body. Inside the box body are arranged a mixing device, a water tank, an air source device, and a foaming device. The mixing device includes a mixing tank fixed to the box body, with one to three feed inlets above the mixing tank and a storage tank connected to the mixing tank below. A slurry gun is connected to the bottom of the storage tank. The foaming device includes a foaming tank and a foaming agent storage tank fixed to the box body. The foaming tank is equipped with a foaming agent mixture feed pipe, a foaming gun, and a... The air source device is connected to an air inlet pipe. The inlet end of the foaming agent mixture feed pipe is connected to a water tank device and an electric proportional peristaltic pump via a high-pressure cleaner. The outlet end is connected to a foaming tank, and the electric proportional peristaltic pump is connected to a foaming agent storage tank. The water tank device includes a water tank fixed on a body, with an outlet pipe, an inlet pipe, and a water gun connected to the foaming agent mixture feed pipe. The inlet pipe is connected to an external water source, and the outlet pipe is connected to the feed port. The inner wall of the feed port has a cleaning hole, and the outer wall has a first inlet pipe connected to the cleaning hole. The foaming gun and slurry gun are both connected to a mixing gun. This equipment is fully automated, replacing traditional split foamed lightweight soil production equipment. It can meet the pouring operations of municipal road and bridge subgrades, underground structures, port water conservancy, mine backfilling, and other projects. It does not require assembly and can directly carry out pouring operations, reducing time costs.

[0005] In the aforementioned technologies, the foamed lightweight soil work station needs to be hoisted to the construction site using a crane. However, due to its installation on the construction site, the equipment is prone to being unlevel, which can alter the force direction of the sensors, leading to serious measurement inaccuracies. Tilting the equipment can also cause unevenness in the liquid surface of the foamed lightweight soil mixture in the hopper. When pumping, the valves or piston cylinders may suck in air instead of the mixture, resulting in a "flow interruption." Once air enters the conveying pipeline, it can cause unstable pressure and interrupted delivery. The mixture will stagnate in the pipe and quickly solidify, leading to serious pipe blockage accidents. If the measurement of water and foaming agent is inaccurate, the density of the poured lightweight soil will not reach the design value. This density deviation will directly lead to substandard compressive strength, and uneven settlement or cracking may occur later. Summary of the Invention

[0006] This application provides a lightweight soil pouring device and its construction method, aiming to solve the problem of tilting of lightweight soil pouring devices placed on the ground in related technologies.

[0007] First aspect:

[0008] The lightweight soil casting equipment provided in this application adopts the following technical solution:

[0009] A lightweight soil casting device and its construction method are disclosed, comprising a base and a lightweight soil casting device body disposed on the base. The base is provided with a support assembly for supporting the lightweight soil casting device body. The support assembly includes a support plate slidably connected to the base and a support spring fixed to the support plate. A calibration assembly is provided on the support assembly. The calibration assembly includes a sliding rail fixed to the support plate, a calibration rod slidably connected within the sliding rail, and a calibration wheel rotatably connected to the calibration rod. The calibration wheel protrudes from the lower surface of the support plate. The sliding rail is inclined towards the center of the base. A first limiting spring and a second limiting spring are disposed within the sliding rail. One end of the first limiting spring is fixed to the sliding rail, and the other end is fixed to the calibration rod. One end of the second limiting spring is fixed to the sliding rail, and the other end is fixed to the calibration rod. During the descent of the lightweight soil casting device body, when the ground is inclined, the calibration wheel abuts against a higher position and then slides towards a lower position on the ground, supporting the base at the lower position.

[0010] By adopting the above technical solution, the lightweight soil casting equipment body is hoisted to the installation ground by a crane. The lightweight soil casting equipment is then slowly lowered by the crane. Because the calibration wheel protrudes from the lower surface of the support plate, during the descent of the lightweight soil casting equipment body, when the ground is tilted, the calibration wheel abuts against the higher position. At this time, the calibration wheel protruding from the lower surface of the support plate first contacts the higher position of the ground. Then, as the lightweight soil casting equipment body continues to fall, under the action of the tilting sliding track, the calibration wheel will slide along the tilted ground from the higher position to the lower position. After the support plate abuts against the ground, as the lightweight soil casting equipment body continues to fall, the base will also abut against the ground, and the support spring will be compressed. Finally, the lowest position of the tilted ground is supported by the calibration wheel and the calibration rod, which can keep the lightweight soil casting equipment body placed on the tilted ground in a horizontal state.

[0011] Optionally, the leveling assembly includes multiple leveling shafts rotatably connected to the support plate, a leveling plate fixed to the leveling shafts, and a leveling spring fixed to the support plate. One end of the leveling spring is fixed to the support plate, and the other end is fixed to the leveling plate. The leveling spring causes the leveling plate to be tilted. The support plate is provided with a linkage assembly for connecting the pushing assembly and the calibration rod, and a pushing assembly for pushing the leveling plate to rotate around the leveling shaft. The pushing assembly causes the leveled leveling plate to abut against the ground.

[0012] By adopting the above technical solution, under the action of the leveling spring, the leveling spring makes the leveling plate position at the edge of the support plate higher than the other end of the diagonal. During the process of the calibration wheel moving down, the linkage component and the pushing component work simultaneously, which will push the leveling plate to rotate around the leveling axis, so that the leveling plate abuts against the inclined ground, thereby achieving the purpose of further supporting the base.

[0013] Optionally, the pushing assembly includes a rotating sleeve rotatably connected to the support plate, a first pushing rod slidably connected to the rotating sleeve, and a second pushing rod threadedly connected to the first pushing rod. The second pushing rod is slidably connected to the support plate, and the lower end of the first pushing rod abuts against the upper surface of the adjusting plate. The linkage assembly is used to drive the rotating sleeve to rotate on the support plate.

[0014] By adopting the above technical solution, during the downward rotation of the adjustment plate, the linkage component drives the rotating sleeve to rotate, which in turn drives the first push rod to rotate. Since the second push rod is slidably connected to the support plate, the first push rod will drive the second push rod to slide on the support plate. The upper surface of the upward-moving second push rod abuts against the base. During the downward movement of the support plate and the base, the base will push the second push rod downward. Since the first push rod and the second push rod are connected by threads, the downward movement of the second push rod will push the first push rod downward. The lower end face of the first push rod pushes the adjustment plate to rotate around the axis of the leveling shaft, thereby allowing the adjustment plate to abut against the inclined ground, achieving the purpose of conveniently adjusting the position of the adjustment plate.

[0015] Optionally, the linkage assembly includes a first rotating wheel rotatably connected to the sliding track and a second rotating wheel fixed to the rotating sleeve, as well as a linkage belt wound around the first rotating wheel and the second rotating wheel. A linkage block is fixedly installed on the linkage belt, and the calibration rod is fixed on the linkage block.

[0016] By adopting the above technical solution, when the calibration wheel slides from a higher slope to a lower slope on the ground, the calibration rod and the linkage block on the calibration wheel move simultaneously along the inclined sliding track. Since the linkage block is fixed on the linkage belt, the linkage belt will move during the movement of the linkage block. During the movement of the linkage belt, the first rotating wheel and the second rotating wheel will rotate simultaneously. During the rotation of the second rotating wheel, the rotating sleeve will rotate. The rotating sleeve will drive the first push rod to rotate, thereby achieving the purpose of facilitating the adjustment of the rotating sleeve.

[0017] Optionally, four adjusting plates and four adjusting shafts are provided. The four adjusting plates block the second opening on the support plate. The adjusting shafts are located at the four corners of the support plate. The adjusting springs and the adjusting shafts are arranged along the diagonal of the adjusting plates. The four adjusting plates form a conical structure that is high in the middle and low on both sides.

[0018] Optionally, a limiting groove is provided on the second push rod, the limiting groove is provided along the length direction of the second push rod, and a limiting rod is fixedly installed on the support plate, the limiting rod being inserted into the limiting groove.

[0019] By adopting the above technical solution, the second push rod slides more stably on the support plate under the action of the limiting groove and the limiting block.

[0020] Optionally, the length of the first limiting spring is less than the length of the second limiting spring.

[0021] By adopting the above technical solution, since the length of the first limiting spring is less than the length of the second limiting spring, the calibration rod is positioned close to the leveling shaft, which facilitates the movement of the calibration rod on the adjustment plate.

[0022] Optionally, a universal ball is rotatably connected to the upper end face of the calibration rod, and the universal ball abuts against the inner wall of the sliding track.

[0023] By adopting the above technical solution, the friction between the calibration rod and the sliding track can be reduced during the sliding process of the calibration rod and calibration wheel under the action of the omnidirectional ball.

[0024] Optionally, the support plate is provided with a second opening, the second opening on the support plate is disposed downward, and the base is provided with a first opening, the first opening on the base is also disposed downward.

[0025] The second aspect:

[0026] A method for pouring lightweight soil includes the following steps:

[0027] S1: The staff leveled the ground where the lightweight soil pouring equipment was placed, hoisted the lightweight soil pouring equipment body above the installation ground, and slowly lowered the lightweight soil pouring equipment body.

[0028] S2: The calibration wheel is in contact with the ground. When the level ground is tilted, the calibration wheel slides from the ground height to the lower part.

[0029] S3: During the sliding process of the calibration wheel, the linkage component drives the rotating sleeve to rotate, the rotating sleeve drives the first push rod to rotate, the first push rod pushes the second push rod to move upward, so that the upper end of the second push rod abuts against the top wall of the first opening;

[0030] S4: The base moves down, pushing the second push rod down. The second push rod drives the first push rod down. The lower end of the first push rod moves down, pushing the adjusting plate to rotate downward and abut against the inclined ground.

[0031] By adopting the above technical solution, during the descent of the lightweight soil pouring equipment, when the ground is tilted, the calibration wheel abuts against the higher position. At this time, the calibration wheel extending from the lower surface of the support plate first contacts the higher position of the ground. Then, as the lightweight soil pouring equipment continues to fall, under the action of the tilting sliding track, the calibration wheel slides along the tilted ground from the higher position to the lower position. After the support plate abuts against the ground, the lightweight soil pouring equipment continues to fall, and the base also abuts against the ground. The support spring is compressed, and finally, the lowest point of the tilted ground is supported by the calibration wheel and calibration rod, creating a linkage. The component drives the rotating sleeve to rotate, which in turn drives the first push rod to rotate. Since the second push rod is slidably connected to the support plate, the first push rod will drive the second push rod to slide on the support plate. The upper surface of the rising second push rod abuts against the base. During the downward movement of the support plate and the base, the base will push the second push rod downward. Since the first push rod and the second push rod are connected by threads, the second push rod will push the first push rod downward during its downward movement. The lower end face of the first push rod pushes the adjusting plate to rotate around the axis of the adjusting shaft, thereby allowing the adjusting plate to abut against the inclined ground, achieving the purpose of conveniently adjusting the position of the adjusting plate.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The calibration wheel will slide along the inclined ground from a higher position to a lower position. After the support plate abuts the ground, as the lightweight soil pouring equipment body continues to fall, the base will also abut the ground. The support spring is compressed. Finally, the lowest position of the inclined ground is supported by the calibration wheel and calibration rod, so that the lightweight soil pouring equipment body placed on the inclined ground is still in a horizontal state.

[0034] 2. The adjusting plate rotates around the adjusting axis, so that the adjusting plate abuts against the inclined ground, thereby achieving the purpose of further supporting the base. Attached Figure Description

[0045] The following combination Figures 1-9 This application will be described in further detail.

[0046] First aspect

[0047] This application discloses a lightweight soil casting device. (Refer to...) Figures 1 to 4 A lightweight soil casting device includes a base 1 and a lightweight soil casting device body 11 disposed on the base 1. The base 1 is provided with a support component 2 for supporting the lightweight soil casting device body 11. The support component 2 is provided with a leveling component 3 and a calibration component 4. The calibration component 4 is used to adjust the position of the leveling component 3 so that the base 1 and the lightweight soil casting device body 11 disposed on the base 1 are horizontally positioned on the ground.

[0048] Reference Figures 1 to 5The support assembly 2 includes a support plate 21 and a support spring 22 fixed on the support plate 21. The end of the support spring 22 away from the support plate 21 is fixed on the base 1. The support plate 21 is provided with a second opening 13, which faces downward. At the same time, the base 1 is provided with a first opening 12, which also faces the ground. The support plate 21 is slidably connected to the first opening 12 on the base 1, and the side of the support plate 21 abuts against the inner wall of the first opening 12. The base 1 has a frame structure under the action of the first opening 12, and the support plate 21 also has a frame structure under the action of the second opening 13.

[0049] Reference Figures 2 to 5 The leveling assembly 3 includes multiple leveling shafts 31 rotatably connected to the support plate 21, leveling plates 32 fixed to the leveling shafts 31, and leveling springs 33 fixed to the support plate 21. One end of the leveling spring 33 is fixed to the support plate 21, and the other end is fixed to the leveling plate 32. In this embodiment, four leveling plates 32 and four leveling shafts 31 are provided. The four leveling plates 32 can block the second opening 13 on the support plate 21. The leveling shafts 31 are provided at the four corners of the support plate 21. The leveling springs 33 and the leveling shafts 31 are arranged along the diagonal of the leveling plates 32. Under the action of the leveling springs 33, the position of the leveling plates 32 near the leveling shafts 31 is higher, and the position near the leveling springs 33 is lower. Under the action of the four leveling plates 32, the four leveling plates 32 form a conical structure with a high middle and low sides in the second opening 13. Since the adjusting plate 32 will rotate around the adjusting shaft 31 at the edge, in this embodiment, the adjusting spring 33 is set as a tension spring, so that the adjusting spring 33 can maintain an arc shape during the rotation of the adjusting plate 32.

[0050] Reference Figures 2 to 5The calibration assembly 4 includes a sliding rail 41 fixed within the second opening 13, a calibration rod 42 slidably connected within the sliding rail 41, and a calibration wheel 43 rotatably connected to the calibration rod 42. The sliding rail 41 is inclined towards the center of the base 1, so that the position of the sliding rail 41 near the leveling shaft 31 is lower and the position away from the leveling shaft 31 is higher. A mounting sleeve is slidably connected within the sliding rail 41, and the calibration rod 42 passes through the mounting sleeve. At the same time, a first limiting spring 5 and a second limiting spring 51 are provided within the sliding rail 41. The first limiting spring 5 is located near the leveling shaft 31, and the second limiting spring 51 is located near the leveling shaft 31. Spring 33 is provided, and the length of the first limiting spring 5 is less than the length of the second limiting spring 51. One end of the first limiting spring 5 is fixed on the sliding rail 41, and the other end is fixed on the mounting sleeve. One end of the second limiting spring 51 is also fixed on the sliding rail 41, and the other end is fixed on the mounting sleeve. The first limiting spring 5 and the second limiting spring 51 are provided on both sides of the calibration rod 42. Under the action of the mounting sleeve, it is convenient to install the first limiting spring 5 and the second limiting spring 51. In the initial state, the first limiting spring 5 and the second limiting spring 51 are both at their natural length, and then the calibration wheel 43 protrudes from the lower surface of the support plate 21.

[0051] To facilitate the sliding of the calibration rod 42 on the sliding track 41, a universal ball 52 is rotatably connected to the upper end face of the calibration rod 42. The universal ball 52 abuts against the top wall of the sliding track 41. By setting the universal ball 52, the friction between the calibration rod 42 and the sliding track 41 can be reduced during the sliding process of the calibration rod 42 and the calibration wheel 43.

[0052] Since the length of the first limiting spring 5 is less than the length of the second limiting spring 51, in the initial state, the calibration rod 42 and the calibration wheel 43 are positioned close to the leveling shaft 31. In order to facilitate the calibration wheel 43 extending out of the leveling plate 32, a clearance groove is provided on the leveling plate 32. The calibration wheel 43 passes through the clearance groove through the leveling plate 32 and then comes into contact with the ground.

[0053] Workers leveled and compacted the uneven ground where the lightweight soil pouring equipment body 11 would be placed. Since the ground was set on the construction site, the uneven ground would still be tilted after being leveled. At this time, the lightweight soil pouring equipment body 11 was hoisted onto the leveled ground by a crane. The adjustment component 4 was then adjusted to make the adjustment plate 32 abut against the leveled ground, so that the lightweight soil pouring equipment body 11 placed on the leveled ground was in a horizontal state.

[0054] Reference Figures 3 to 9A pushing component 6 and a linkage component 7 are provided on the support plate 21. The linkage component 7 connects the pushing component 6 and the calibration rod 42. During the movement of the calibration rod 42, the linkage component 7 drives the pushing component 6 to work. The pushing component 6 pushes the adjusting plate 32 to rotate around the adjusting shaft 31, and then makes the leveled adjusting plate 32 abut against the ground. Since there are four adjusting plates 32, in this embodiment, there are four pushing components 6 and four linkage components 7, with each of the four pushing components 6 and four linkage components 7 corresponding to one of the four adjusting plates 32.

[0055] Reference Figures 4 to 9 The pushing assembly 6 includes a rotating sleeve 61 rotatably connected to the support plate 21, a first pushing rod 62 slidably connected to the rotating sleeve 61, and a second pushing rod 63 threadedly connected to the first pushing rod 62. The second pushing rod 63 is slidably connected to the support plate 21. Due to the setting of the leveling spring 33, the position of the first pushing rod 62 can be limited, and then the lower end of the first pushing rod 62 abuts against the upper surface of the leveling plate 32. In this embodiment, the rotating sleeve 61 can only be rotatably connected to the support plate 21 and cannot slide on the support plate 21. The second push rod 63 can only slide on the support plate 21 and cannot rotate on the support plate 21; the linkage component 7 is used to drive the rotating sleeve 61 to rotate on the support plate 21. Since the first push rod 62 slides on the rotating sleeve 61, the first push rod 62 will rotate during the rotation of the rotating sleeve 61. The first push rod 62 is threadedly connected to the second push rod 63, and the second push rod 63 slides on the support plate 21. At this time, the second push rod 63 will move upward, and finally the upper end of the second push rod 63 will abut against the lower surface of the base 1.

[0056] To facilitate the sliding of the first push rod 62 on the rotating sleeve 61, the first push rod 62 includes a sliding part and a limiting part. The sliding part is slidably connected inside the rotating sleeve 61, and the sliding part is set as a rectangular structure, while the limiting part is set as a cylindrical structure. The cross-section of the limiting part is larger than the cross-section of the sliding part. At this time, the rotating sleeve 61 can drive the sliding part and the limiting part to rotate, while the sliding part can slide on the rotating sleeve 61.

[0057] Reference Figures 3 to 9 A limiting groove 8 is provided on the second push rod 63. The limiting groove 8 is set along the length direction of the second push rod 63. A limiting rod 9 is fixedly installed on the support plate 21. The limiting rod 9 is inserted into the limiting groove 8. Then, under the action of the limiting groove 8 and the limiting rod 9, the first push rod 62 will drive the second push rod 63 to move up and down during rotation.

[0058] The adjusting plate 32 is positioned within the first opening 12, and in its initial state, the height of the adjusting plate 32 at the middle position of the first opening 12 is lower than the height at the edge. The leveling spring 33 is at its natural length, and the lower end of the first push rod 62 abuts against the upper surface of the adjusting plate 32. When the crane lifts the lightweight soil pouring equipment body 11 above the installation ground and slowly lowers the lightweight soil pouring equipment, if the ground tilts (left side higher than right side), the left alignment wheel 43 will first contact the higher part of the ground. As the lightweight soil pouring equipment body 11 continues to fall... As the calibration wheel 43 is in contact with the ground and is subjected to downward pressure from the lightweight soil pouring equipment body 11, under the action of the inclined track, the calibration wheel 43 will move along the inclined ground towards the lower position (from left to right). When the calibration wheel 43 drives the calibration rod 42 to move on the sliding track 41, the linkage component 7 will drive the first push rod 62 to rotate. The first push rod 62 drives the second push rod 63 to move upward. Then the upper end of the second push rod 63 will abut against the top wall of the first opening 12 until all four calibration wheels 43 abut against the ground.

[0059] When all four calibration wheels 43 are in contact with the ground, the lower surface of the support plate 21 is not yet in contact with the ground. As the lightweight soil pouring equipment body 11 falls, the lower surface of the support plate 21 comes into contact with the ground. Then the lightweight soil pouring equipment body 11 continues to fall, and the support spring 22 is gradually compressed. Finally, the lower surface of the base 1 also comes into contact with the ground. During the simultaneous downward movement of the base 1 and the lightweight soil pouring equipment body 11, the second push rod 63 will be pushed downward. Since the first push rod 62 and the second push rod 63 are connected by threads, and the first push rod 62 slides on the rotating sleeve 61, the second push rod 63 will move downward at the same time as the first push rod 62. The lower end face of the first push rod 62 pushes the inclined adjusting plate 32 to rotate downward around the axis of the adjusting shaft 31. The lower surface of the rotating adjusting plate 32 will come into contact with the inclined ground. The lightweight soil pouring equipment body 11 is leveled by the adjusting plate 32, so that the lightweight soil pouring equipment body 11 that has fallen to the ground is in a horizontal state. After the support plate 21 touches the ground, the lightweight soil pouring equipment body 11 continues to fall. At this time, the base 1 will gradually move closer to the ground, and the calibration wheel 43 will be inserted into the ground, thereby fixing the position of the lightweight soil pouring equipment body 11 and improving the stability of the lightweight soil pouring equipment body 11 on the ground.

[0060] Once the ground, after being prepared by the workers, shows no tilt, the crane lifts the lightweight soil pouring equipment body 11 above the installation ground and slowly lowers it. Simultaneously, the four alignment wheels 43 on the support plate 21 contact the ground. As the lightweight soil pouring equipment body 11 falls, the lower surface of the support plate 21 contacts the ground. Then, as the lightweight soil pouring equipment body 11 continues to fall, the support spring 22 is gradually compressed, and the lower surface of the base 1 also contacts the ground. During the simultaneous descent of the base 1 and the lightweight soil pouring equipment body 11, the top wall of the first opening 12 contacts the upper surface of the second push rod 63, thus pushing the second push rod 63 downwards. As the first push rod 62 and the second push rod 63 are connected by threads, and the first push rod 62 slides on the rotating sleeve 61, the second push rod 63 will move down at the same time as the first push rod 62. The lower end face of the first push rod 62 pushes the inclined adjusting plate 32 to rotate downward around the axis of the adjusting shaft 31. The rotating adjusting plate 32 comes into contact with the flat ground. Since the ground is flat, the lower surface of the adjusting plate 32 after landing is in contact with the ground, so that the lightweight soil pouring equipment body 11 on the ground is in a horizontal state. At the same time, the calibration wheel 43 is inserted into the leveled ground to fix the lightweight soil pouring equipment body 11 placed on the ground.

[0061] Reference Figures 3 to 9 The linkage component 7 includes a first rotating wheel 71 rotatably connected to the sliding rail 41 and a second rotating wheel 72 fixed to the rotating sleeve 61, and a linkage belt 73 wound around the first rotating wheel 71 and the second rotating wheel 72. A linkage block 74 is fixedly installed on the linkage belt 73, and the calibration rod 42 is fixed on the linkage block 74. When the calibration wheel 43 slides on the inclined ground, it will drive the calibration rod 42 to move on the sliding rail 41. When the calibration rod 42 moves, it will drive the linkage block 74 to move. The linkage block 74 will drive the linkage belt 73 to move. The linkage belt 73 will drive the first rotating wheel 71 and the second rotating wheel 72 to rotate. Through the rotation of the second rotating wheel 72, the second rotating wheel 72 will drive the rotating sleeve 61 to rotate. Through the rotating sleeve 61, the first push rod 62 will rotate, and then the position of the second push rod 63 will be adjusted.

[0062] The implementation principle of a lightweight soil casting device according to an embodiment of this application is as follows: When the crane hoists the lightweight soil casting device body 11 to the installation ground, the lightweight soil casting device body 11 is slowly lowered. When the ground tilts, the left calibration wheel 43 will first contact the higher part of the ground. As the lightweight soil casting device body 11 continues to fall, since the calibration wheel 43 is in contact with the ground and is subjected to the downward pressure of the lightweight soil casting device body 11, under the action of the inclined track, the calibration wheel 43 will move along the inclined ground towards the lower part. When the calibration wheel 43 drives the calibration rod 42 to move on the sliding track 41, the linkage component 7 will drive the first push rod 62 to rotate. The first push rod 62 drives the second push rod 63 to move upward. Then the upper end of the second push rod 63 will abut against the top wall of the first opening 12 until all four calibration wheels 43 abut against the ground.

[0063] When all four calibration wheels 43 are in contact with the ground, the lower surface of the support plate 21 is not yet in contact with the ground. As the lightweight soil pouring equipment body 11 falls, the lower surface of the support plate 21 comes into contact with the ground. Then the lightweight soil pouring equipment body 11 continues to fall, and the support spring 22 is gradually compressed. Finally, the lower surface of the base 1 also comes into contact with the ground. During the simultaneous downward movement of the base 1 and the lightweight soil pouring equipment body 11, the second push rod 63 will be pushed downward.

[0064] Since the first push rod 62 and the second push rod 63 are connected by threads, and the first push rod 62 slides on the rotating sleeve 61, the second push rod 63 will move down simultaneously with the first push rod 62. The lower end face of the first push rod 62 pushes the inclined adjusting plate 32 to rotate downward around the axis of the adjusting shaft 31. The lower surface of the rotating adjusting plate 32 will abut against the inclined ground. The adjusting plate 32 will level the lightweight soil pouring equipment body 11, so that the lightweight soil pouring equipment body 11 is in a horizontal state when it falls to the ground. After the support plate 21 abuts against the ground, the lightweight soil pouring equipment body 11 continues to fall. At this time, the base 1 will gradually move towards the ground, and the calibration wheel 43 will be inserted into the ground, thereby fixing the position of the lightweight soil pouring equipment body 11 and improving the stability of the lightweight soil pouring equipment body 11 on the ground.

[0065] The second aspect:

[0066] A method for pouring lightweight soil includes the following steps:

[0067] S1: The staff leveled the ground where the lightweight soil pouring equipment was placed, hoisted the lightweight soil pouring equipment body 11 above the installation ground, and slowly lowered the lightweight soil pouring equipment body 11.

[0068] S2: When the calibration wheel 43 is in contact with the ground, and the level ground is tilted, the calibration wheel 43 slides from the ground height to the lower position;

[0069] S3: During the sliding process of the calibration wheel 43, the linkage component 7 drives the rotating sleeve 61 to rotate, the rotating sleeve 61 drives the first push rod 62 to rotate, and the first push rod 62 pushes the second push rod 63 to move upward, so that the upper end of the second push rod 63 abuts against the top wall of the first opening 12;

[0070] S4: The base 1 moves down, pushing the second push rod 63 down. The second push rod 63 drives the first push rod 62 down. The lower end of the first push rod 62 pushes the adjusting plate 32 to rotate downward and abut against the inclined ground.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
