Description

Technical Field

[0001] This invention belongs to the field of transfer tools, specifically a transfer device and method for the construction of ALC lightweight partition wall panels. Background Technology

[0002] ALC lightweight partition wall panels, also known as autoclaved aerated concrete panels, are a new type of energy-saving building product. ALC lightweight partition wall panels have many advantages, such as light weight, good sound insulation and heat insulation, low cost, simple installation process, and short construction period requirements. This makes them widely used in the interior and exterior walls of high-rise frame buildings and industrial plants. Due to their thinness, they can also effectively expand the usable area of ​​the building when used as wall panels.

[0003] At construction sites, ALC lightweight partition panels are typically moved using transfer devices. Current transfer and positioning devices for ALC lightweight partition panel construction usually take the form of a mobile trolley. This involves wheels on the bottom of a base plate and a clamping mechanism on the top of the base plate to secure the ALC lightweight partition panels. The wheels at the bottom of the base move the trolley, thus facilitating the transfer of the ALC lightweight partition panels. These wheels not only move the panels but also secure the base to a designated position on the ground during loading (the ALC lightweight partition panels are placed onto the clamping mechanism) or unloading (after being moved into place, the ALC lightweight partition panels are unloaded from the clamping mechanism). For example, Chinese patent application CN202321821492.1 discloses a transfer and positioning device for ALC lightweight partition panel construction; and application 202310055978.7 discloses a transfer and positioning device and its usage method for ALC lightweight partition panel construction, both relying solely on wheels for support. However, relying solely on the casters for support makes it difficult to guarantee stability during loading and unloading, which may lead to base movement and make it difficult to ensure stable clamping of the sheet metal.

[0004] However, this patent uses a hydraulic cylinder to drive the auxiliary wheels to lift and lower, ensuring the stability of the device. But when loading and unloading, the base is supported only by lifting the casters and auxiliary wheels. During the loading process, the base may move, affecting the loading and unloading work. The stability is poor and the work efficiency is affected. Summary of the Invention

[0005] The purpose of this invention is to provide a transfer device and method for constructing ALC lightweight partition boards, thereby improving the support stability during loading and unloading operations.

[0006] The technical solution adopted in this invention is: ALC lightweight partition wall panel construction transfer device, including a base plate, with a walking wheel installed at the bottom of the base plate; a placement frame is provided at the top of the base plate, and a door is installed at the rear end of the placement frame; two vertical and oppositely arranged positioning plates are slidably installed in the placement frame along the horizontal direction; and a set of support devices is configured on each of the two positioning plates.

[0007] The support device includes a drive rack, a support plate, and a rotating shaft; the drive rack is welded to the bottom of the positioning plate and extends laterally; the rotating shaft is rotatably installed in the placement frame, and a drive gear is installed on the rotating shaft, which meshes with the drive rack; one end of the top surface of the support plate is connected to a transmission block, and the other end is connected to a directional block; both the transmission block and the directional block are vertically movably inserted into the base plate; the transmission block is internally threaded with a support screw, and one end of the support screw extending into the placement frame is connected to the rotating shaft via a belt drive.

[0008] Furthermore, the transmission block and the orientation block are square in shape, and a square groove adapted to the transmission block and the orientation block is provided on the base plate. The transmission block and the orientation block are movably inserted into the square groove of the base plate.

[0009] Furthermore, a fixed block and a support rod are fixed at the bottom of the placement frame corresponding to the support plate. A sliding block that slides vertically with the fixed block is inserted into the outer periphery of the fixed block, and an auxiliary wheel is installed at the bottom of the sliding block. A driven slider is welded to one side of the sliding block, and an active slider is welded to one side of the support plate. A movable rod is movably hinged to the top of the support rod. Slots extending along the length direction are opened at both ends of the movable rod, and the active slider and the driven slider are movably inserted into the corresponding slots.

[0010] Furthermore, a wheel axle is rotatably installed inside the placement frame, and a positioning gear is fixedly mounted on the wheel axle. Connecting plates are fixed to the front ends of the two positioning plates respectively. One connecting plate is fixed with a laterally extending active rack plate, and the other connecting plate is fixed with a laterally extending driven rack plate. The active rack plate and the driven rack plate are arranged opposite each other and both mesh with the positioning gear.

[0011] Furthermore, the placement frame has a groove adapted to the connecting plate, and the groove extends laterally; the connecting plate is inserted into the groove and slides with the groove laterally.

[0012] Furthermore, a support plate is provided inside the placement frame, and four symmetrically arranged dampers are installed between the support plate and the bottom wall of the placement frame.

[0013] Furthermore, two buffer sliders are installed between the support plate and the bottom wall of the placement frame; two fixed rods are fixed to the bottom wall of the placement frame, and the buffer sliders are fitted onto the fixed rods and slide along the axis of the fixed rods; a buffer spring is provided between the buffer sliders and the bottom wall of the placement frame, and the buffer spring is fitted onto the fixed rods; a buffer rod is provided between the buffer sliders and the bottom wall of the support plate, with one end of the buffer rod hinged to the bottom wall of the support plate and the other end hinged to the buffer sliders.

[0014] Furthermore, two fixed columns are welded to the top of the base plate, and lifting screws are movably inserted into the fixed columns. A rotating ring is rotatably installed on the top of the fixed columns, and the rotating ring is threaded onto the lifting screws. A handle is welded to the top of both lifting screws.

[0015] Furthermore, the door has two panels, one of which is rotatably mounted with a locking rod, and the other is welded with a locking block, the locking rod and the locking block being compatible.

[0016] The method for using the transfer device for ALC lightweight partition wall panel construction includes the following steps:

[0017] Step 1: Open the switch door and pull the positioning plate to increase the distance between the two positioning plates. At this time, the positioning plate drives the drive rack to move, the drive rack drives the drive gear to rotate, the drive gear drives the shaft to rotate through the synchronous belt, and the shaft drives the support screw to rotate. The rotation of the support screw drives the transmission block to move. Through the restriction of the square groove and the directional block, the transmission block and the directional block drive the support plate to move vertically downward and support it on the ground.

[0018] Step 2: Place the ALC lightweight partition board onto the load-bearing plate;

[0019] Step 3: Push the positioning plate to move, so that the gap between the two positioning plates is reduced and the ALC lightweight partition board is clamped. At this time, the positioning plate drives the drive rack to move in the opposite direction, the drive rack drives the drive gear to rotate in the opposite direction, the drive gear drives the shaft to rotate through the synchronous belt, and the shaft drives the support screw to rotate. The rotation of the support screw drives the transmission block to move. Through the restriction of the square groove and the directional block, the transmission block and the directional block drive the support plate to move vertically upward, leaving the ground, and the traveling wheel is supported on the ground.

[0020] The beneficial effects of this invention are as follows: When placing the wall panel by moving the positioning plate, the support screw rotates, driving the support plate to move downwards and support the ground, thus improving the stability of the support and ensuring the stability of the base and placement frame during loading and unloading; furthermore, the movement of the positioning plate drives the support plate to rise or fall synchronously with the rise or fall of the support plate, eliminating the need to operate the positioning plate and support plate separately, thereby saving operation steps and time while maintaining the overall stability of the device and improving work efficiency.

[0021] The use of auxiliary wheels to assist in the movement of the placement frame improves its stability. Furthermore, the coordinated movement of the support plate, active slider, movable rod, and driven slider ensures that the auxiliary wheels move synchronously with the support plate, guaranteeing stability during loading and unloading of materials into the base and placement frame. This eliminates the need for separate stabilization operations, saving time and effort while maintaining stability, thus improving work efficiency.

[0022] By engaging the active rack plate, the driven rack plate, and the positioning gear, when one positioning plate is driven to move, the other positioning plate moves synchronously. This allows a single person to move the positioning plates, saving manpower and improving practicality.

[0023] By incorporating dampers, buffer blocks, and other structural elements, if vibrations occur during transport, the load-bearing plate drives the buffer rod, which in turn reduces vibration through the buffer slider and buffer spring. Combined with the use of dampers, this enhances the vibration reduction effect and ensures the stability of the device during transport. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] In this invention, the terms "longitudinal," "lateral," "vertical," "upper," "front," "rear," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientation or positional relationship shown is for the purpose of describing the invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0033] Transfer device for ALC lightweight partition wall panel construction, such as Figure 1 , Figure 2 and Figure 4 As shown, the system includes a base plate 1, with wheels 14 mounted on its bottom; a placement frame 2 is mounted on top of the base plate 1. The placement frame 2 is typically a square frame with an open top, formed by a bottom wall and outer side walls. The base plate 1 with wheels resembles a flatbed cart. The length of the placement frame 2 is defined as longitudinal, its width as transverse, and its depth as vertical. Therefore, along the longitudinal direction of the placement frame 2, one end is the front end and the other end is the rear end; along the transverse direction, one side is the left side and the other side is the right side; along the vertical direction, one side is the top and the other side is the bottom.

[0034] A switchable door 4 is installed at the rear end of the placement frame 2. When the switchable door 4 is open, ALC lightweight partition boards can be placed into the placement frame 2 through the door opening. After the ALC lightweight partition boards are stacked, the switchable door 4 is closed for transfer. The switchable door 4 can take various forms, such as a single-leaf swing door. In this embodiment, the switchable door 4 has two leaves, one of which is rotatably equipped with a locking rod 5, and the other is welded with a locking block 6. The locking rod 5 and the locking block 6 are compatible. The door is closed by inserting the locking rod into the locking block 6.

[0035] Two vertically oriented and oppositely positioned positioning plates 3 are slidably installed within the placement frame 2. That is, the two positioning plates 3 are parallel to each other, with one positioning plate 3 on the left and the other on the right. One positioning plate 3 can be moved laterally to fit against the other positioning plate 3, and both positioning plates 3 can move left and right. The function of the positioning plates 3 is to clamp the ALC lightweight partition board and prevent it from moving within the placement frame 2. Specifically, when the ALC lightweight partition board needs to be placed into the placement frame 2, the positioning plates 3 are first moved to increase the distance between the two positioning plates 3, and the ALC lightweight partition board is placed between the two positioning plates 3. After placement, the positioning plates 3 are moved again, with one positioning plate 3 abutting against the ALC lightweight partition board from the left and the other positioning plate 3 abutting against the ALC lightweight partition board from the right.

[0036] Each of the two positioning plates 3 is equipped with a support device; the support device includes a drive rack 22, a support plate 12, and a rotating shaft 20; the drive rack 22 is welded to the bottom of the positioning plate 3 and extends laterally; the rotating shaft 20 is rotatably installed in the placement frame 2, and a drive gear 21 is installed on the rotating shaft 20, which meshes with the drive rack 22; one end of the top surface of the support plate 12 is connected to a transmission block 17, and the other end is connected to a directional block 16; both the transmission block 17 and the directional block 16 are vertically movably inserted into the base plate 1, that is, under the restriction of the base plate 1, the transmission block 17 can only move vertically, and the directional block 16 can only move vertically, and cannot rotate relative to the base plate 1. The transmission block 17 is internally threaded with a support screw 18, that is, the transmission block 17 is provided with a vertical internal thread hole, and the internal thread hole is threadedly connected to the support screw 18. The end of the support screw 18 extending into the placement frame 2 is connected to the rotating shaft 20 via a belt drive. In this structure, when placing or removing ALC lightweight partition panels, the positioning plate 3 needs to move laterally away. As the positioning plate 3 moves away, the drive rack 22 welded to it moves accordingly, driving the drive gear 21 to rotate. The rotation of the drive gear 21 drives the rotating shaft 20 to rotate, and the rotating shaft 20 transmits the motion to the support screw 18 via the synchronous belt 19, causing the support screw 18 to rotate synchronously. Because the base plate 1 restricts the rotation of the transmission block 17 and the directional block 16, the transmission block 17 moves vertically downward under the threaded engagement of the support screw 18 and the transmission block 17, causing the support plate 12 to descend and support the ground. The support plate 12 has a large contact area with the ground, thus improving the stability of the support.

[0037] Conversely, when the positioning plate 3 moves laterally closer, the drive rack 22 welded to the positioning plate 3 follows the movement, driving the drive gear 21 meshing with it to rotate. The rotation of the drive gear 21 drives the rotating shaft 20 to rotate, and the rotating shaft 20 transmits the motion to the support screw 18 via the synchronous belt 19, causing the support screw 18 to rotate synchronously. Since the base plate 1 restricts the rotation of the transmission block 17 and the directional block 16, the transmission block 17 moves vertically upward under the threaded engagement of the support screw 18 and the transmission block 17, causing the support plate 12 to rise off the ground, with only the traveling wheels 14 supporting the ground, facilitating movement.

[0038] Since the movement of the positioning plate 3 causes the support plate 12 to rise or fall, the movement of the positioning plate 3 and the rise or fall of the support plate 12 are synchronized. There is no need to operate the positioning plate 3 and the support plate 12 separately. This allows the device to maintain stability while saving operation steps and time, and improving work efficiency.

[0039] There are many ways to prevent relative rotation between the transmission block 17 and the base plate 1, and between the directional block 16 and the base plate 1. For example, a through hole with a groove can be made in the base plate 1, and protrusions can be provided on the transmission block 17 and the directional block 16. The protrusions are inserted into the grooves of the through hole to achieve limiting. In this embodiment, the transmission block 17 and the directional block 16 are square in shape, and a square groove adapted to the transmission block 17 and the directional block 16 is made in the base plate 1. The transmission block 17 and the directional block 16 are movably inserted into the square groove of the base plate 1. The square block and the square groove cooperate to automatically limit the rotation and prevent rotation. Its structure is simple and easy to manufacture.

[0040] During use, the length of the placement frame 2 is often greater than that of the base plate 1, and the rear end of the placement frame 2 cantileveres from the base plate 1. To better support and transport the placement frame 2 during transportation, such as... Figure 1 , Figure 2 and Figure 3As shown, auxiliary wheels 15 are installed on both sides of the rear end of the placement frame 2. When moving, the auxiliary wheels 15 can cooperate with the traveling wheels 14 to move. In this embodiment, a fixed block 7 and a support rod 9 are fixed at the bottom of the placement frame 2 corresponding to the support plate 12. A sliding block 8 is inserted into the outer periphery of the fixed block 7 and slides vertically with the fixed block 7, that is, the sliding block 8 can move up and down along the fixed block 7. An auxiliary wheel 15 is installed at the bottom end of the sliding block 8; a driven slider 11 is welded to one side of the sliding block 8, an active slider 13 is welded to one side of the support plate 12, and a movable rod 10 is movably hinged to the top of the support rod 9; the two ends of the movable rod 10 are respectively provided with sliding grooves extending along its length direction, and the active slider 13 and the driven slider 11 are respectively movably inserted into the corresponding sliding grooves. When the support plate 12 moves downward, it drives the active slider 13 downward. Constrained by the sliding groove on the movable rod 10, the movable rod 10 rotates around the hinge point. The end of the movable rod 10 adjacent to the driven slider 11 tilts upward, driving the driven slider 11 upward, thereby driving the sliding block 8 upward, and the auxiliary wheel 15 is lifted. Conversely, the auxiliary wheel 15 is lowered. This achieves simultaneous movement of the positioning plate 3, the rising or falling of the support plate 12, and the lifting and lowering of the auxiliary wheel 15, ensuring the stability of the base and placement frame during loading and unloading. Furthermore, it eliminates the need for separate operations to achieve stability, saving operation steps and time while maintaining stability, thus improving work efficiency.

[0041] In this embodiment, both the traveling wheels and the auxiliary wheels are swivel wheels.

[0042] To achieve synchronous movement of the two positioning plates 3, preferably, as follows: Figure 1 and Figure 5 As shown, an axle 26 is rotatably mounted inside the placement frame 2, and a positioning gear 27 is fixedly fitted onto the axle 26. Connecting plates 23 are fixed to the front ends of two positioning plates 3 respectively. One connecting plate 23 has a laterally extending active rack plate 24 fixed to it, and the other connecting plate 23 has a laterally extending driven rack plate 25 fixed to it. The active rack plate 24 and driven rack plate 25 are arranged vertically opposite each other and both mesh with the positioning gear 27. With this structure, only one positioning plate 3 needs to be subjected to external force to move laterally. The active rack plate 24 on it follows the lateral movement, driving the meshing positioning gear 27 to rotate. The positioning gear 27 then drives the meshing driven rack plate 25 to move, thus achieving synchronous or opposite movement of the two positioning plates 3. Only one side of the positioning plate 3 needs to be moved, saving manpower and improving practicality. To move the positioning plates 3, a pull rod is installed on the outer side of one of the positioning plates 3. One end of the pull rod can pass through the side wall of the placement frame 2 and protrude outside the placement frame. Pulling the pull rod can make the two positioning plates 3 move in opposite directions, and pushing the pull rod can make the two positioning plates 3 move towards each other. The outer side of the positioning plate 3 is relative to the inner side. The inner side is the side facing the positioning plate 3, and the outer side is the side facing away from the other positioning plate 3.

[0043] To improve the stability and reliability of the synchronous movement of the two positioning plates 3, preferably, a groove adapted to the connecting plate 23 is provided in the placement frame 2, and the groove extends laterally; the connecting plate 23 is inserted into the groove and slides in the groove laterally. One end of the connecting plate 23 is connected to the positioning plate 3, and the other end is inserted into the groove. Both ends are supported, resulting in small bending deformation, which can better enable the rack plate on it to mesh with the gear 27, thereby ensuring the stability and reliability of the synchronous movement of the positioning plates 3.

[0044] To improve the stability of the equipment operation and mitigate vibrations generated during transport, such as Figure 6 As shown, a support plate 28 is provided inside the placement frame 2, and four symmetrically arranged dampers 29 are installed between the support plate 28 and the bottom wall of the placement frame 2.

[0045] To more effectively mitigate vibrations during transport, preferably, two buffer sliders 30 are installed between the support plate 28 and the bottom wall of the placement frame 2; two fixing rods 31 are fixed to the bottom wall of the placement frame 2, and the buffer sliders 30 are fitted onto the fixing rods 31 and slide along the axial direction of the fixing rods 31; a buffer spring is provided between the buffer sliders 30 and the bottom wall of the placement frame 2, and the buffer spring is fitted onto the fixing rods 31; a buffer rod 32 is provided between the buffer sliders 30 and the bottom wall of the support plate 28, with one end of the buffer rod 32 hinged to the bottom wall of the support plate 28 and the other end hinged to the buffer sliders 30.

[0046] If vibration occurs during the transfer process, the bearing plate 28 drives the buffer rod 32 to move, the buffer rod 32 drives the buffer slider 30 to move, and the buffer slider 30 compresses the buffer spring. The elastic performance of the buffer spring achieves a limited buffering and shock absorption effect. With the use of the damper 29, the shock absorption effect is better, ensuring the stability of the device during the transfer operation and ensuring the stability of the wall panel during the transfer process.

[0047] To facilitate the movement of the device by staff, preferably, two fixed posts 33 are welded to the top of the base plate 1. A lifting screw 34 is movably inserted into each fixed post 33. A rotating ring 36 is rotatably mounted on the top of each fixed post 33, and the rotating ring 36 is threaded onto the lifting screw 34. A handle 35 is welded to the top of both lifting screws 34. Rotating the two rotating rings 36 moves the lifting screws 34, thereby adjusting the height of the handle 35, making the device more comfortable for people of different heights to use.

At this time, the positioning plate (3) drives the drive rack (22) to move in the opposite direction. The drive rack (22) drives the drive gear (21) to rotate in the opposite direction. The drive gear (21) drives the shaft (20) to rotate through the synchronous belt (19) so that the shaft (20) drives the support screw (18) to rotate. The rotation of the support screw (18) drives the transmission block (17) to move. Through the restriction of the square groove and the directional block (16), the transmission block (17) and the directional block (16) drive the support plate (12) to move vertically upward and leave the ground. The walking wheel (14) is supported on the ground.
