Description

Technical Field

[0001] This invention belongs to the field of construction hoist technology, specifically an intelligent curved ladder construction hoist. Background Technology

[0002] A curved ladder construction hoist is a special lifting equipment that can run along a curved guide rail frame and is used to transport personnel and materials during the construction of curved buildings (such as cooling towers, bridge piers, power towers, etc.).

[0003] Patent CN218201659U discloses a construction hoist, including a lifting frame, which forms the frame of the hoist. A motor base is located on the right side of the lifting frame. This patent overcomes the shortcomings of existing technologies by incorporating a dust collector fan, a dust collector fan door, a control switch, and an impeller. When the control switch is activated, the internal servo motor is driven, which in turn drives the impeller to rotate. This process draws dust floating around the motor into a collection box inside the dust collector fan, ensuring timely cleaning of the dust. This prevents dust from accumulating inside or outside the motor over time, which could lead to malfunctions and affect the later performance of the hoist. It also extends the lifespan of the motor and protects the internal components from damage.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: Curved ladder construction hoists are equipped with lifting cabins, and in most cases, the lifting cabins are used to move the panels to a designated height, whereby personnel at higher positions can then retrieve the panels from the lifting cabins.

[0005] Normally, the boards are placed in the lifting chamber in a stacked state. During the lifting process, the boards are prone to slippage or even tipping over due to vibration, which affects the normal access of the boards by personnel at height. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes an intelligent curved ladder construction hoist.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an intelligent curved ladder construction hoist, including a curved lifting frame and a lifting cabin, wherein a cabin door is provided on one side of the lifting cabin, the lifting cabin is driven on the curved lifting frame, and a plate placement auxiliary component is provided inside the lifting cabin; The plate placement auxiliary component includes two mounting plates. One mounting plate is fixedly connected to the lower surface of the inner cavity of the lifting chamber, and the other mounting plate is slidably connected to the lower surface of the inner cavity of the lifting chamber. The upper surface of the mounting plate is provided with a screw guide rail module three, and the two moving ends of the screw guide rail module three are fixedly connected to limit plates.

[0008] Preferably, a cylinder is fixedly connected to one side of the lower surface of the inner cavity of the lifting chamber, and the piston end of the cylinder is fixedly connected to one end of a mounting plate on one side.

[0009] Preferably, the lifting chamber is further equipped with a retrieval auxiliary component; The retrieval auxiliary component includes two bases that are symmetrically and fixedly connected to the lower surface of the inner cavity of the lifting chamber. Both sides of the upper surface of the bases are fixedly connected to the bonding plates, and multiple spacers are slidably inserted into the bonding plates along the vertical direction.

[0010] Preferably, a support column is fixedly connected to one side of the bottom of the inner cavity of the lifting chamber. A first lead screw guide module is provided on one side of the support column. A lifting plate is fixedly connected to the moving end of the first lead screw guide module. A scissor telescopic mechanism is provided on one side of the lifting plate. An adjusting plate is fixedly connected to one end of the scissor telescopic mechanism. A second lead screw guide module is provided on one side of the adjusting plate. A slider is provided on the second lead screw guide module. A support rod is fixedly connected to one side of the slider. A push rod is slidably connected to the bottom groove of the adjusting plate along the lateral direction.

[0011] Preferably, an extrusion rod is slidably connected to one side of the bonding plate, a winding roller is rotatably connected to the bottom side of the bonding plate, a blocking strip is wound on the winding roller, the end of the blocking strip is fixedly connected to one side of the extrusion rod, a limit block is fixedly connected to one side of the bonding plate, and the blocking strip passes through the limit block.

[0012] Preferably, a motor is fixedly connected to one side of the lower end of the bonding plate, the output end of the motor is fixedly connected to the rotating end of the winding roller, and a lead screw guide module four is provided on one side of the bonding plate, the moving end of the lead screw guide module four is fixedly connected to one end of the extrusion rod.

[0013] Preferably, a spring is fixedly connected to one side of the partition block, and the other end of the spring is fixedly connected to the bonding plate.

[0014] Preferably, a second cylinder is fixedly connected to the top of the two limiting plates on the right side, and a sliding plate is fixedly connected to the piston end of the second cylinder, and the sliding plate is slidably connected to the limiting plates.

[0015] Preferably, the lower end of the push rod is threadedly connected to a threaded rod, both ends of which are rotatably connected to an adjustment plate. One end of the adjustment plate is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to one end of the threaded rod.

[0016] The beneficial effects of this invention are as follows: 1. The intelligent curved ladder construction hoist of the present invention utilizes a plate placement auxiliary component. Four limiting plates cooperate to form a rectangular placement frame for placing the plate. The distance between two mounting plates is adjusted according to the length and width of the plate, ensuring the distance matches the plate length. Subsequently, the two moving ends of the lead screw guide rail module three simultaneously drive the two limiting plates to move towards or away from each other, thereby adjusting the distance between the two limiting plates.

[0017] The rectangular placement frame can be adjusted to match the size of the board material using the above method, and then multiple boards can be stacked in the frame. Multiple limiting plates work together to clamp the stacked boards, thereby improving the stability of the boards during stacking. The lifting chamber rises along the curved lifting frame, and even if the lifting chamber vibrates, it is not easy for the boards to shift or slip, thus ensuring the normal retrieval of the boards later.

[0018] 2. The intelligent curved ladder construction hoist of the present invention utilizes an auxiliary component to place each board on two partitions when the board is placed in a rectangular placement frame, with a certain gap between adjacent boards.

[0019] Depending on the required quantity of sheet material, the lifting plate is moved up and down using the screw guide module to adjust its height, ensuring the bottom of the lifting plate aligns with the corresponding gap. Then, the scissor telescopic mechanism drives the adjusting plate to move laterally, allowing its bottom to pass through the gap. Subsequently, the screw guide module drives the extrusion rod to slide downwards, moving it away from multiple spacers in sequence. Simultaneously, the motor drives the winding roller to rotate, winding up the blocking strip. Under the action of the springs, the multiple spacers are reset sequentially from top to bottom, moving them away from the bottom of the sheet material.

[0020] When the spacer moves away from the bottom of the board, the board will fall downwards along the limiting plate, and multiple boards will overlap and be placed on the bottom of the adjusting plate. Then, the second screw guide module drives the slider downwards, and the support rod presses down the top of the board, thus securing the specified number of boards on the adjusting plate. Subsequently, the second cylinders on both sides drive the sliding plates on both sides to move, so that the sliding plates are no longer in contact with the edges of the board.

[0021] At this point, the storage door opens, and the scissor-lift telescopic mechanism can again drive the adjusting plate to move laterally, placing it above the platform. Then, the support rod moves upward, releasing its pressure on the plate. Next, motor two drives the threaded rod to rotate, causing the push rod to slide along the bottom of the adjusting plate. This push rod then pushes the plate placed on the adjusting plate, allowing it to slide onto the platform. This achieves control over the number of plates retrieved and automatic plate placement, thereby improving retrieval efficiency. Attached Figure Description

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please refer to Figures 1-8 The present invention provides a technical solution: an intelligent curved ladder construction hoist, including a curved lifting frame 1 and a lifting chamber 2, a chamber door 3 on one side of the lifting chamber 2, the lifting chamber 2 being driven on the curved lifting frame 1, and a plate placement auxiliary component inside the lifting chamber 2; The plate placement auxiliary component includes two mounting plates 10. One mounting plate 10 is fixedly connected to the lower surface of the inner cavity of the lifting chamber 2, and the other mounting plate 10 is slidably connected to the lower surface of the inner cavity of the lifting chamber 2. The upper surface of the mounting plate 10 is provided with a screw guide rail module 3 19, and the two moving ends of the screw guide rail module 3 19 are fixedly connected to limit plates 12.

[0027] In this embodiment, as Figure 3 As shown, a cylinder 11 is fixedly connected to one side of the lower surface of the inner cavity of the lifting chamber 2, and the piston end of the cylinder 11 is fixedly connected to one end of the mounting plate 10 on one side.

[0028] Specifically, in the existing technology, the curved ladder construction hoist is equipped with a lifting chamber 2, and in most cases, the lifting chamber 2 is used to move the board to a designated height, and then the board is picked up by personnel at a higher position.

[0029] Normally, the boards are placed in the lifting chamber 2 in a stacked state. However, during the lifting process, the boards inside the lifting chamber 2 are prone to slippage or even tipping over due to vibration, which affects the normal access of the boards by personnel at height.

[0030] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Four limiting plates 12 cooperate to form a rectangular placement frame, which is used to place the board.

[0031] Based on the length and width of the sheet material, cylinder 11 and lead screw guide module 319 are activated respectively. Cylinder 11 drives the mounting plate 10 on one side to slide at the bottom of the lifting chamber 2, thereby adjusting the distance between the two mounting plates 10 and matching the length of the sheet material. Subsequently, the two moving ends of lead screw guide module 319 simultaneously drive the two limiting plates 12 to move towards or away from each other, thereby adjusting the distance between the two limiting plates 12.

[0032] The rectangular placement frame can be adjusted to match the size of the board material using the above method, and then multiple boards can be stacked in the frame. Multiple limiting plates 12 work together to clamp the stacked boards, thereby improving the stability of the boards when stacked. The lifting chamber 2 then rises along the curved lifting frame 1. Even if the lifting chamber 2 vibrates, it is not easy for the boards to shift or slip, thus ensuring the normal retrieval of the boards later.

[0033] In this embodiment, as Figures 2-8 As shown, the elevator 2 is also equipped with retrieval auxiliary components; The auxiliary components include two bases 21 that are symmetrically and fixedly connected to the lower surface of the inner cavity of the lifting chamber 2. Both sides of the upper surface of the bases 21 are fixedly connected to the bonding plates 17, and multiple partitions 22 are slidably inserted into the bonding plates 17 along the vertical edge.

[0034] A support column 4 is fixedly connected to one side of the bottom of the inner cavity of the lifting chamber 2. A screw guide rail module 1 5 is provided on one side of the support column 4. A lifting plate 7 is fixedly connected to the moving end of the screw guide rail module 1 5. A scissor telescopic mechanism 8 is provided on one side of the lifting plate 7. An adjusting plate 9 is fixedly connected to one end of the scissor telescopic mechanism 8. A screw guide rail module 2 13 is provided on one side of the adjusting plate 9. A slider 15 is provided on the screw guide rail module 2 13. A support rod 18 is fixedly connected to one side of the slider 15. A push rod 16 is slidably connected to the bottom groove of the adjusting plate 9 along the lateral direction.

[0035] A pressing rod 30 is slidably connected to one side of the bonding plate 17, and a winding roller 20 is rotatably connected to the bottom side of the bonding plate 17. A blocking strip 6 is wound on the winding roller 20. The end of the blocking strip 6 is fixedly connected to one side of the pressing rod 30. A limiting block 28 is fixedly connected to one side of the bonding plate 17, and the blocking strip 6 passes through the limiting block 28.

[0036] A motor 14 is fixedly connected to one side of the lower end of the bonding plate 17. The output end of the motor 14 is fixedly connected to the rotating end of the winding roller 20. A lead screw guide module 29 is provided on one side of the bonding plate 17. The moving end of the lead screw guide module 29 is fixedly connected to one end of the extrusion rod 30.

[0037] A spring 23 is fixedly connected to one side of the partition 22, and the other end of the spring 23 is fixedly connected to the bonding plate 17.

[0038] The top of the two limit plates 12 on the right side is fixedly connected to the cylinder 26, and the piston end of the cylinder 26 is fixedly connected to the sliding plate 27, which is slidably connected to the limit plate 12.

[0039] The lower end of the push rod 16 is threadedly connected to a threaded rod 24. Both ends of the threaded rod 24 are rotatably connected to the adjusting plate 9. One end of the adjusting plate 9 is fixedly connected to a motor 25. The output end of the motor 25 is fixedly connected to one end of the threaded rod 24.

[0040] Specifically, in the above embodiments, although multiple limiting plates 12 can be used to limit the stacked boards to prevent the boards from shifting or tipping over during the lifting process of the lifting chamber 2, it is difficult to place a specified number of boards on the high platform when the lifting chamber 2 rises to a designated height and the operator retrieves the boards, thus affecting the retrieval efficiency.

[0041] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the boards are placed in the rectangular placement frame, each board is placed on two spacers 22, and there will be a certain gap between adjacent boards.

[0042] Based on the required quantity of sheet material, the height of the lifting plate 7 is adjusted using the screw guide module 5, so that the bottom of the adjusting plate 9 is aligned with the corresponding gap. Then, the scissor telescopic mechanism 8 drives the adjusting plate 9 to move laterally, so that the bottom of the adjusting plate 9 passes through the gap. Subsequently, the screw guide module 29 drives the extrusion rod 30 to slide downward, so that the extrusion rod 30 moves away from the multiple partitions 22 in sequence. At the same time, the motor 14 drives the winding roller 20 to rotate, winding the blocking belt 6. Then, under the action of the spring 23, the multiple partitions 22 are reset from top to bottom in sequence, so that the partitions 22 are away from the bottom of the sheet material.

[0043] When the spacer 22 moves away from the bottom of the board, the board will fall downwards along the limiting plate 12, and multiple boards will be placed together and stacked on the bottom of the adjusting plate 9. Then, the lead screw guide module 2 13 drives the slider 15 to move downwards, and the support rod 18 presses down on the top of the board, so that a specified number of boards are stably placed on the adjusting plate 9. Then, the two side cylinders 26 drive the sliding plates 27 on both sides to move, so that the sliding plates 27 are no longer in contact with the edge of the board.

[0044] At this point, the door 3 opens, allowing the scissor-fork telescopic mechanism 8 to drive the adjusting plate 9 laterally, moving it above the platform. Then, the support rod 18 moves upward, releasing it from pressing against the material. Next, motor 25 drives the threaded rod 24 to rotate, causing the push rod 16 to slide along the bottom of the adjusting plate 9. The push rod 16 then pushes the material placed on the adjusting plate 9, allowing it to slide onto the platform. This achieves control over the quantity of material retrieved and automatic placement, thereby improving retrieval efficiency.

[0045] Working principle: Four limiting plates 12 cooperate with each other to form a rectangular placement frame, which is used to place the board.

[0046] Based on the length and width of the sheet material, cylinder 11 and lead screw guide module 319 are activated respectively. Cylinder 11 drives the mounting plate 10 on one side to slide at the bottom of the lifting chamber 2, thereby adjusting the distance between the two mounting plates 10 and matching the length of the sheet material. Subsequently, the two moving ends of lead screw guide module 319 simultaneously drive the two limiting plates 12 to move towards or away from each other, thereby adjusting the distance between the two limiting plates 12.

[0047] The rectangular placement frame can be adjusted to match the size of the board material using the above method, and then multiple boards can be stacked in the frame. Multiple limiting plates 12 work together to clamp the stacked boards, thereby improving the stability of the boards when stacked. The lifting chamber 2 then rises along the curved lifting frame 1. Even if the lifting chamber 2 vibrates, it is not easy for the boards to shift or slip, thus ensuring the normal retrieval of the boards later.

[0048] When the boards are placed in the rectangular placement frame, each board is placed on two spacers 22, and there will be a certain gap between adjacent boards.

[0049] Based on the required quantity of sheet material, the height of the lifting plate 7 is adjusted using the screw guide module 5, so that the bottom of the adjusting plate 9 is aligned with the corresponding gap. Then, the scissor telescopic mechanism 8 drives the adjusting plate 9 to move laterally, so that the bottom of the adjusting plate 9 passes through the gap. Subsequently, the screw guide module 29 drives the extrusion rod 30 to slide downward, so that the extrusion rod 30 moves away from the multiple partitions 22 in sequence. At the same time, the motor 14 drives the winding roller 20 to rotate, winding the blocking belt 6. Then, under the action of the spring 23, the multiple partitions 22 are reset from top to bottom in sequence, so that the partitions 22 are away from the bottom of the sheet material.

[0050] When the spacer 22 moves away from the bottom of the board, the board will fall downwards along the limiting plate 12, and multiple boards will be placed together and stacked on the bottom of the adjusting plate 9. Then, the lead screw guide module 2 13 drives the slider 15 to move downwards, and the support rod 18 presses down on the top of the board, so that a specified number of boards are stably placed on the adjusting plate 9. Then, the two side cylinders 26 drive the sliding plates 27 on both sides to move, so that the sliding plates 27 are no longer in contact with the edge of the board.

[0051] At this point, the door 3 opens, allowing the scissor-fork telescopic mechanism 8 to drive the adjusting plate 9 laterally, moving it above the platform. Then, the support rod 18 moves upward, releasing it from pressing against the material. Next, motor 25 drives the threaded rod 24 to rotate, causing the push rod 16 to slide along the bottom of the adjusting plate 9. The push rod 16 then pushes the material placed on the adjusting plate 9, allowing it to slide onto the platform. This achieves control over the quantity of material retrieved and automatic placement, thereby improving retrieval efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
