Description

Technical Field

[0001] This application relates to the technical field of prefabricated diaphragm wall hoisting, and in particular to a prefabricated diaphragm wall vertical hoisting device and method. Background Art

[0002] Prefabricated ground-connected walls are prefabricated in advance according to the installation location, and splicing structures are set on both sides of the ground-connected walls. The splicing structures include splicing flanges and splicing grooves. The splicing flanges and splicing grooves are respectively set on both sides of the prefabricated ground-connected walls. The prefabricated ground-connected walls are transported to the installation location for direct installation and splicing, which greatly improves the installation speed and construction efficiency of the ground-connected walls.

[0003] However, existing technologies for hoisting precast diaphragm walls have certain drawbacks. In existing technologies, hoisting involves connecting a crane's lifting rope to one end of the precast diaphragm wall. During the hoisting process, the crane needs to continuously move towards the end of the precast diaphragm wall that contacts the ground until the entire precast diaphragm wall is lifted. However, during the movement of the crane, the center of gravity of the crane is very unstable, which may cause the crane to tip over during the hoisting of the precast diaphragm wall. Therefore, a vertical hoisting device and method for precast diaphragm walls is needed. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a prefabricated ground-connected wall vertical lifting device and method, which is used to solve the technical problems of certain defects in the existing technology for the lifting of prefabricated ground-connected walls.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a prefabricated diaphragm wall vertical hoisting device, including a rotating platform and a driving device installed on both sides of the rotating platform for driving the rotating platform to move. The rotating platform includes a vertical plate and a horizontal plate. The vertical plate is perpendicular to the horizontal plate and fixedly connected to the horizontal plate. A rotating shaft is provided at the connection between the vertical plate and the horizontal plate. The rotating shaft is arranged along the width direction of the vertical plate and the horizontal plate and passes through the vertical plate and the horizontal plate.

[0006] Furthermore, the driving device includes fixed plates located on both sides of the vertical plate and the horizontal plate, a supporting plate fixedly connected to the bottom end of the fixed plate, and a movable wheel installed on the bottom surface of the supporting plate. The two ends of the rotating shaft pass through the two fixed plates respectively and are rotatably connected to the fixed plates. A driving motor for driving the movable wheel to move is installed on one side of the movable wheel.

[0007] The jack is then lowered to the ground so that the bottom surface of the jack is in contact with the end surface of the horizontal plate and the vertical plate, and then the hoisting structure on the jack is disassembled, and then the other end of the jack is hoisted and the jack is gradually hoisted into a vertical state. At the same time, the driving motor is started to move the rotating platform toward the crane. In this way, when hoisting the prefabricated floor jack, the crane does not need to move. It is only necessary to lift the prefabricated floor jack and move it toward the crane through the rotating platform. During the movement, the prefabricated floor jack gradually becomes vertical, and the vertical plate and the horizontal plate also rotate so that the horizontal plate is in a vertical state and the vertical plate is in a horizontal state, so that the center of gravity of the crane is always kept in one position. In this way, the center of gravity of the crane is stable during the construction process and will not tip over, and the difficulty of hoisting the prefabricated floor jack is greatly reduced.

[0008] Furthermore, a missing-round weight is fixedly connected to the bottom surface of the horizontal plate and the side of the vertical plate that is vertically away from the horizontal plate.

[0009] By adopting the above technical solution, although the arrangement of the vertical plate and the horizontal plate reduces the difficulty of hoisting the prefabricated floor connecting wall, when the prefabricated floor connecting wall is hoisted and placed on the vertical plate and the horizontal plate, due to the arrangement of the rotating shaft, the vertical plate and the horizontal plate may be in a state on the driving device with the side of the vertical plate vertically away from the horizontal plate facing upward, while the horizontal plate is perpendicular to the ground, resulting in the need for manual support of the vertical plate and the horizontal plate when the prefabricated floor connecting wall is placed in order to facilitate the placement of the prefabricated floor connecting wall. However, the prefabricated floor connecting wall is very heavy and may fall off the crane during the hoisting process. If someone is holding the vertical plate and the horizontal plate at this time, it is very easy to be injured. The setting of the sinker solves this technical problem. The incomplete sinker is connected to the bottom surface of the horizontal plate and the side of the vertical plate vertically away from the horizontal plate, so that the incomplete sinker can apply a clockwise rotating gravity to the horizontal plate and a counterclockwise rotating gravity to the side of the vertical plate vertically away from the horizontal plate. The two offset each other to keep the vertical plate in a vertical state, so that the side of the horizontal plate adjacent to the vertical plate faces upward. In this way, when moving the prefabricated ground connection wall to the vertical and horizontal plates, you only need to adjust their positions without manually holding the vertical and horizontal plates to place the prefabricated ground connection wall on the rotating platform, thereby improving the safety of hoisting the ground connection wall.

[0010] Furthermore, the driving device is equipped with a damping device, which includes a damping baffle and fixing devices arranged on both sides of the bottom end of the damping baffle, and the damping baffle has impact resistance.

[0011] Furthermore, the fixing device includes positioning plates located on both sides of the bottom end of the damping baffle and two positioning pins passing through the two positioning plates respectively.

[0012] While the above technical solution reduces the operational difficulty of hoisting precast diaphragm walls, when the precast diaphragm wall is almost vertical, the small angle between the precast diaphragm wall and the crane's lifting rope, along with the inertia of the drive unit, causes the drive unit to move the rotating platform too far. This results in the precast diaphragm wall not being lifted vertically by the crane but instead tilting. The drive unit then needs to move backward to verticalize the diaphragm wall, but at this point, most of the diaphragm wall's weight is applied to the drive unit, causing it to move backward. The installation of a damping device solves this technical problem. After hoisting one end of the precast diaphragm wall onto the rotating platform, the construction workers use measuring tools to determine the approximate distance the rotating platform needs to move to reach a vertical position. Then, at the endpoint of this distance, the damping device is installed. The damping plate is fixed in place by driving positioning pins through the positioning plate and into the ground. In this way, when the precast diaphragm wall is about to reach a vertical position and is about to overshoot due to inertia, the damping plate will stop the drive device and the rotating platform from overshooting, thus ensuring that the precast diaphragm wall is hoisted in a vertical position. This makes it much easier for the construction workers to hoist the precast diaphragm wall.

[0013] Furthermore, a support device is provided on the side of the damping baffle away from the drive device and the rotating platform.

[0014] Furthermore, the support device includes support plates disposed on both sides of the damping baffle and a support baffle disposed between the two support plates. The support baffle is rotatably connected to the support plates, and the support plates are located on the upper half of the damping baffle.

[0015] While the damping device makes it easier for construction workers to hoist precast diaphragm walls, the damping baffle is subjected to impact every time it is hoisted. Although the bottom of the damping baffle is fixed, the upper part of the damping baffle is subjected to a large thrust every time it is impacted, making it prone to breakage. The support device solves this problem. When installing the damping baffle, the support baffle is first rotated to support the ground, and then the damping baffle is fixed. In this way, the support baffle can provide support when the damping baffle is impacted, preventing the damping baffle from breaking and improving its service life.

[0016] Furthermore, a buffer device is provided on the side of the damping baffle opposite to the driving device and the rotating platform. The buffer device includes a buffer plate disposed on the opposite side of the two fixed plates and a buffer spring with one end fixedly connected to the damping baffle and the other end facing the buffer plate.

[0017] By adopting the above technical solution, although the setting of the damping device makes it more convenient for construction workers to lift the prefabricated ground connecting wall, the driving device will collide with the damping baffle every time the prefabricated ground connecting wall is moved to the damping baffle, and because of the setting of the supporting device, the damping baffle cannot be bent as a whole, making it very easy to be damaged after the driving device hits the damping baffle. The setting of the buffer device solves this technical problem. When the driving device approaches the damping baffle, the buffer spring will first support the buffer plate, providing a certain resistance to the movement of the driving device. In this way, when the driving device moves to the damping baffle, due to the setting of the buffer spring, the closer the driving device is to the damping baffle, the slower it will move. In this way, the force of the driving device hitting the damping baffle will become smaller, thereby improving the service life of the driving device.

[0018] Furthermore, the buffer plate and the buffer spring have an insertion interface at their center points, and the buffer plate has a guide rod that passes through the insertion interface and through the buffer plate and the damping baffle.

[0019] By adopting the above technical solution, although the setting of the buffer device improves the service life of the driving device, it also causes construction workers to align the buffer spring with the buffer plate when installing the damping device. However, because the damping device is far away from the driving device, it is difficult to align, resulting in the buffer spring often not playing a role when hoisting the prefabricated ground wall. The setting of the guide rod solves this technical problem. When installing the damping device, first use the guide rod to pass through the buffer plate and the damping baffle, so that the guide rod will align the buffer spring with the buffer plate, and there is no need for manual calibration.

[0020] A hoisting method for a prefabricated diaphragm wall vertical hoisting device applied to the above technical solution includes the following steps: S1. Place the prefabricated ground diaphragm horizontally on the ground, then lift one end of the prefabricated ground diaphragm, and then use the drive motor to drive the rotating platform to move to the bottom surface of the prefabricated ground diaphragm. Then lower the prefabricated ground diaphragm so that its bottom surface contacts the horizontal plate and the end surface contacts the vertical plate. S2. Measure the distance the precast diaphragm wall needs to be moved to be vertical. S3. Secure the damping baffle at the endpoint of the measured distance using positioning pins; S4. Pass the guide rod through the connector and then through the buffer plate and damping baffle: S5. Lift the precast diaphragm wall upwards, and simultaneously start the drive motor to move the rotating platform toward the damping baffle: S6. When the precast diaphragm wall is in a vertical position, lift the precast diaphragm wall off the rotating platform, and then hoist the precast diaphragm wall to the installation position for installation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: By setting up the rotating platform and the driving device, the prefabricated ground diaphragm is placed horizontally on the ground, and then one end of the prefabricated ground diaphragm is lifted. Then, the driving motor drives the rotating platform to move to the bottom surface of the prefabricated ground diaphragm, and then the prefabricated ground diaphragm is lowered so that its bottom surface contacts the end surface of the horizontal plate and the vertical plate. Then, the lifting structure on the prefabricated ground diaphragm is disassembled, and then the other end of the prefabricated ground diaphragm is lifted and gradually lifted into a vertical state. At the same time, the driving motor is started to move the rotating platform toward the crane. In this way, when lifting the prefabricated ground diaphragm, the crane does not need to move. It is only necessary to lift the prefabricated ground diaphragm and move it toward the crane through the rotating platform. During the movement, the prefabricated ground diaphragm gradually becomes vertical, and the vertical plate and the horizontal plate also rotate so that the horizontal plate is in a vertical state and the vertical plate is in a horizontal state, so that the center of gravity of the crane is always kept in one position. In this way, the center of gravity of the crane is stable during construction and will not tip over, and the difficulty of lifting the prefabricated ground diaphragm is greatly reduced. By setting up the damping device, it is possible to measure the approximate distance that the rotating platform needs to move to become vertical using a measuring tool, and then install the damping device at the end of the distance. The positioning nails are nailed through the positioning plate and nailed into the ground to fix the damping baffle. In this way, when the prefabricated ground connection wall is about to be vertical and is about to move too far due to inertia, the damping baffle will block the driving device and the rotating platform to prevent them from moving too far. In this way, the prefabricated ground connection wall will be lifted in a vertical state, which can make it more convenient for construction workers to lift the prefabricated ground connection wall. By setting up the supporting device, when installing the damping baffle, it is possible to first rotate the supporting baffle to support the ground, and then fix the damping baffle. In this way, the supporting baffle can provide support force when the damping baffle is hit, preventing the damping baffle from breaking and improving the service life of the damping baffle. Through the setting of the buffer device, when the driving device approaches the damping baffle, the buffer spring will first press against the buffer plate, providing a certain resistance to the movement of the driving device. In this way, when the driving device moves to the damping baffle, due to the setting of the buffer spring, the closer the driving device is to the damping baffle, the slower it moves. In this way, the force with which the driving device hits the damping baffle will become smaller, thereby improving the service life of the driving device. Attached Figure Description

[0024] The present application is further described in detail below with reference to the accompanying drawings.

[0025] Example, refer to Figure 1 、 Figure 2 、 Figure 3 A precast diaphragm wall vertical hoisting device includes a rotating platform 1 and drive devices 2 installed on both sides of the rotating platform 1 for moving the rotating platform 1. The rotating platform 1 includes a vertical plate 10 and a horizontal plate 11. The vertical plate 10 is perpendicular to the horizontal plate 11 and fixedly connected to the horizontal plate 11. A rotating shaft 12 is provided at the connection between the vertical plate 10 and the horizontal plate 11. The rotating shaft 12 is arranged along the width direction of the vertical plate 10 and the horizontal plate 11 and passes through the vertical plate 10 and the horizontal plate 11. The drive device 2 includes fixed plates 20 located on both sides of the vertical plate 10 and the horizontal plate 11, a support plate 21 fixedly connected to the bottom end of the fixed plate 20, and a moving wheel 22 installed on the bottom surface of the support plate 21. The two ends of the rotating shaft 12 pass through the two fixed plates 20 respectively and are rotatably connected to the fixed plates 20. A drive motor 23 for driving the moving wheel 22 is installed on one side of the moving wheel 22. The precast diaphragm wall is placed horizontally on the ground, and then one end of the precast diaphragm wall is hoisted. Then, the drive motor 23 drives the rotating platform 1 to move to the bottom of the precast diaphragm wall. The precast diaphragm wall is then lowered so that its bottom surface contacts the end face of the horizontal plate 11 and the vertical plate 10. The hoisting structure on the precast diaphragm wall is then removed, and the other end of the precast diaphragm wall is hoisted and gradually hoisted into a vertical state. At the same time, the drive motor 23 is started to move the rotating platform 1 toward the crane. In this way, when hoisting the precast diaphragm wall, the crane does not need to move. The precast diaphragm wall is simply hoisted high and moved toward the crane by the rotating platform 1. During the movement, the precast diaphragm wall gradually becomes vertical, and the vertical plate 10 and the horizontal plate 11 also rotate with it, so that the horizontal plate 11 is vertical and the vertical plate 10 is horizontal. This keeps the center of gravity of the crane in one position, so that the center of gravity of the crane is stable during construction and will not tip over. This also greatly reduces the difficulty of hoisting the precast diaphragm wall.

[0026] Although the installation of the vertical plate 10 and horizontal plate 11 reduces the operational difficulty of hoisting the precast diaphragm wall, when placing the precast diaphragm wall on the vertical plate 10 and horizontal plate 11, the position of the vertical plate 10 and horizontal plate 11 on the drive device 2 may be such that the vertical plate 10 is vertical and away from the horizontal plate 11 facing upwards, while the horizontal plate 11 is perpendicular to the ground. This means that the precast diaphragm wall needs to be manually supported by the vertical plate 10 and horizontal plate 11 to facilitate its placement. However, the precast diaphragm wall is very heavy and may detach from the crane during hoisting. If someone is supporting the vertical plate 10 and horizontal plate 11 at this time, they are very likely to be injured by falling debris. To solve this technical problem, this embodiment has a horizontal plate 11 bottom surface and a vertical plate 11... A missing-circle weight 13 is fixedly connected to the vertical side of the slab 10 away from the horizontal slab 11. The missing-circle weight 13 connects the bottom surface of the horizontal slab 11 and the vertical side of the slab 10 away from the horizontal slab 11. This allows the missing-circle weight 13 to apply a clockwise rotational force to the horizontal slab 11 and a counterclockwise rotational force to the vertical side of the slab 10 away from the horizontal slab 11. These two forces cancel each other out, keeping the slab 10 vertical and ensuring that the side of the horizontal slab 11 adjacent to the slab 10 faces upward. Thus, when moving the precast diaphragm wall onto the slab 10 and the horizontal slab 11, only their positions need to be adjusted, and no manual support is required to place the precast diaphragm wall on the rotating platform 1, improving the safety of hoisting the diaphragm wall.

[0027] Although the arrangement of the driving device 2 and the rotating platform 1 reduces the difficulty of hoisting the prefabricated ground-connected wall, when the prefabricated ground-connected wall is about to be in a vertical state, due to the small angle between the prefabricated ground-connected wall and the hoisting rope of the crane and the inertia of the driving device 2, the driving device 2 drives the rotating platform 1 to move too far when the prefabricated ground-connected wall is about to be in a vertical state, resulting in the prefabricated ground-connected wall not being lifted by the crane into a vertical state, but being in an inclined state, causing the driving device 2 to need to move backward to drive the ground-connected wall into a vertical state, but at this time most of the gravity of the ground-connected wall is applied to the driving device 2, resulting in difficulty in the driving device 2 moving backward. In order to solve this technical problem, in this embodiment, the driving device 2 is provided with a damping device 3, which includes a damping baffle 30 and fixing devices arranged on both sides of the bottom end of the damping baffle 30. 31. The damping baffle 30 has impact resistance. The fixing device 31 includes positioning plates 310 located on both sides of the bottom end of the damping baffle 30 and two positioning nails 311 passing through the two positioning plates 310 respectively. After the construction workers hoist one end of the prefabricated ground connecting wall onto the rotating platform 1, they use a measuring tool to measure the approximate distance that the rotating platform 1 needs to move to become vertical, and then install the damping device 3 at the end of the distance. The positioning nails 311 pass through the positioning plates 310 and are nailed into the ground to fix the damping baffle 30. In this way, when the prefabricated ground connecting wall is about to be in a vertical state due to inertia and is about to move too far, the damping baffle 30 will block the driving device 2 and the rotating platform 1 to prevent them from moving too far. In this way, the prefabricated ground connecting wall will be hoisted in a vertical state, which can make it more convenient for construction workers to hoist the prefabricated ground connecting wall.

[0028] Although the setting of the damping device 3 makes it more convenient for construction workers to hoist the prefabricated ground connecting wall, the damping baffle 30 will be hit every time the prefabricated ground connecting wall is hoisted. Although the bottom end of the damping baffle 30 is fixed, the upper half of the damping baffle 30 is fixed at the bottom end, and each time the damping baffle 30 is hit, the upper half of the damping baffle 30 will be subjected to a large thrust, causing the damping baffle 30 to break easily. In order to solve this technical problem, in this embodiment, the damping baffle 30 is provided on a side away from the driving device 2 and the rotating platform 1. There is a supporting device 4, which includes supporting plates 40 arranged on both sides of the damping baffle 30 and a supporting baffle 41 arranged between the two supporting plates 40. The supporting baffle 41 is rotatably connected to the supporting plate 40, and the supporting plate 40 is located in the upper half of the damping baffle 30. When installing the damping baffle 30, first rotate the supporting baffle 41 to support the ground, and then fix the damping baffle 30. In this way, the supporting baffle 41 can provide supporting force when the damping baffle 30 is hit, thereby preventing the damping baffle 30 from breaking and improving the service life of the damping baffle 30.

[0029] Although the setting of the damping device 3 makes it more convenient for construction workers to hoist the prefabricated ground connecting wall, the driving device 2 will collide with the damping baffle 30 every time the prefabricated ground connecting wall is moved to the damping baffle 30. Moreover, due to the setting of the supporting device 4, the damping baffle 30 cannot be bent as a whole, making it very easy for the driving device 2 to be damaged after hitting the damping baffle 30. In order to solve this technical problem, in this embodiment, a buffer device 5 is provided on both sides of the damping baffle 30 relative to the driving device 2 and the rotating platform 1. The buffer device 5 includes a pair of fixed plates 20 arranged on the back of the two fixed plates 20. The buffer plate 50 on the side away from the damping baffle 30 and the buffer spring 51 with one end fixedly connected to the damping baffle 30 and the other end facing the buffer plate 50. When the driving device 2 approaches the damping baffle 30, the buffer spring 51 will first support the buffer plate 50, providing a certain resistance to the movement of the driving device 2. In this way, when the driving device 2 moves to the damping baffle 30, due to the setting of the buffer spring 51, the closer the driving device 2 is to the damping baffle 30, the slower it will move. In this way, the force with which the driving device 2 hits the damping baffle 30 will become smaller, thereby improving the service life of the driving device 2.

[0030] Although the setting of the buffer device 5 improves the service life of the driving device 2, it also requires construction workers to align the buffer spring 51 with the buffer plate 50 when installing the damping device 3. However, because the damping device 3 is far away from the driving device 2, it is difficult to align, which makes the buffer spring 51 often fail to play a role when hoisting the prefabricated ground wall. In order to solve this technical problem, this embodiment provides a plug interface at the center point of the buffer plate 50 and the buffer spring 51, and the buffer plate 50 is provided with a guide rod 52 that passes through the buffer plate 50 and the damping baffle 30 through the plug interface. When installing the damping device 3, first use the guide rod 52 to pass through the buffer plate 50 and the damping baffle 30, so that the guide rod 52 will align the buffer spring 51 with the buffer plate 50, and there is no need for manual calibration, so that the buffer device 5 can be used stably.

[0031] The specific implementation process is as follows: first, the prefabricated ground connecting wall is placed horizontally on the ground, and then one end of the prefabricated ground connecting wall is lifted, and then the rotating platform 1 is driven by the driving motor 23 to move to the bottom surface of the prefabricated ground connecting wall, and then the prefabricated ground connecting wall is lowered so that its bottom surface contacts the horizontal plate 11 and the end surface contacts the vertical plate 10, and then the distance the prefabricated ground connecting wall moves before it becomes vertical is measured, and then the damping baffle 30 is fixed by the positioning nail 311 at the end point of the measured distance, and then the guide rod 52 is used to pass through the buffer plate 50 and the damping baffle 30 through the plug interface, and then the prefabricated ground connecting wall is lifted upward, and at the same time, the driving motor 23 is started to move the rotating platform 1 toward the damping baffle 30. When the prefabricated ground connecting wall is in a vertical state, the prefabricated ground connecting wall is lifted off the rotating platform 1, and then the prefabricated ground connecting wall is lifted to the installation position for installation.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
