Description

Technical Field

[0001] This invention relates to the field of sheet metal hoisting technology, specifically to an aluminum sheet metal hoisting device. Background Technology

[0002] Aluminum panels are a commonly used building material due to their lightweight, corrosion resistance, ease of processing, and aesthetic appeal. They are often used for exterior wall decoration, interior ceilings, and partitions. However, with the increasing complexity of architectural designs, the hoisting of large-sized and irregularly shaped aluminum panels has become a technical challenge, requiring specialized hoisting equipment and skills.

[0003] Chinese patent document CN114715768B discloses a prefabricated building wall panel hoisting system and method. It includes a panel and a hoisting mechanism, with a hoisting space for placing the panel within the mechanism. The hoisting mechanism includes a lower fixing component and an upper fixing block, which combine to form the hoisting space. This patent document uses an inward-retracting component to shrink the entire hoisting space inward, thus fixing the panel. During hoisting, the panel is restricted by guide wires, allowing it to move upward only along the cableway. This ensures that hoisting is completed regardless of the crane's lifting position, as long as force is applied above the panel. Furthermore, the hoisted panel precisely aligns with its installation location, facilitating installation by workers and preventing swaying of the panel during upward movement due to wind.

[0004] In the above technical solution, a cableway is used to lift and lower the aluminum plate during transportation. However, in actual construction, the aluminum plate needs to be hoisted to the installation position for direct installation. The cableway can only transport the plate to a fixed position. In addition, the above technical solution is effective for transporting plates with a stable center of gravity. However, for plates whose center of gravity is not at the geometric center, such as plates with pre-drilled holes, the plate will be tilted when fixed. During hoisting, the plate will deflect and cause collisions. When hoisted to the installation position, the plate is tilted and it is difficult to align the plate with the base hole. Summary of the Invention

[0005] This invention provides an aluminum sheet hoisting device, which aims to solve the problem in related technologies where the sheet deflects after being hoisted, making it difficult to install the sheet.

[0006] An aluminum sheet hoisting device includes a hoisting rod and a hoisting rope. Fixed pulleys are installed at both ends of the hoisting rod, and the hoisting rope is wound around the two fixed pulleys. A rope clamp is installed between the two fixed pulleys, sliding along the left-right direction of the hoisting rod and used to clamp the hoisting rope. Two abutment plates are also installed on the hoisting rod, respectively located on both sides of the rope clamp and sliding along the left-right direction on the hoisting rod. A pushing assembly is also installed on the hoisting rod to push the two abutment plates to move synchronously in opposite directions. A perforated insert rod slides elastically up and down within each abutment plate. When the insert rod moves downwards, it inserts into the movable end of the pushing assembly. A wedge block is installed in the middle of the hoisting rod. When the wedge block inserts into the hole on the insert rod, it pushes the insert rod upwards and disengages from the pushing assembly. The movable end of the pushing assembly is connected to a clamping assembly for clamping the hoisting rope.

[0007] When lifting the panels, it can prevent the panels from being bumped or bruised due to a shift in the center of gravity; after the panels are lifted, the center of gravity of the panels is adjusted under their own weight, and the tension of the lifting ropes is balanced to prevent the panels from falling; when the panels are lifted to the vicinity of the base, the clamping components and drive components pull the panels upwards a certain distance before lowering them, which facilitates the installation of the panels.

[0008] Preferably, the pushing component includes a drive motor, a gear, and two racks; the drive motor is mounted on the hoisting rod, the gear is mounted on the output end of the drive motor, and the two racks are located on the upper and lower sides of the two gears respectively; the pushing component drives the pushing plate and the clamping component to move.

[0009] Preferably, the lifting rod has sliding grooves on its front and rear inner walls, and the two racks slide in the front and rear sliding grooves respectively; this guides the movement of the racks.

[0010] Preferably, the hoisting rod is also equipped with a left-right sliding track, and the rope clamp slides within the sliding track; this guides the movement of the rope clamp.

[0011] Preferably, a buffer spring is installed on the side of the abutment plate near the rope clamp to prevent excessive impact force from the rope clamp on the abutment plate.

[0012] Preferably, a return spring is provided between the insertion rod and the abutment plate, so that the wedge block can automatically return to its original position after it is disengaged from the insertion rod.

[0013] Preferably, the clamping assembly includes a base, on which a downward hydraulic rod is disposed, and a cavity adapted to the suspension rope is formed between the base and the end of the hydraulic rod, and the rope is clamped when the end of the hydraulic rod approaches the base.

[0014] Preferably, the wedge block is provided with an electric telescopic rod to drive the wedge block to move toward the insertion rod; this prevents the wedge block from being unable to be inserted into the insertion rod when the buffer spring has no compression margin.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0016] When hoisting the sheet material, the hoisting boom rises to tighten the hoisting rope, and then the rope clamp clamps the hoisting rope. The hoisting boom then rises a certain distance to lift the sheet material. At this time, the sheet material is lifted horizontally to avoid bumping the edges and corners of the sheet material during hoisting.

[0017] After the plate is lifted a certain distance, the rope clamp releases the rope and pushes the abutment plate to move slowly toward the fixed pulley by the push assembly until the abutment plate disengages from the rope clamp. At this time, the clamping assembly clamps the plate, and the tension on the lifting rope is basically the same, making the lifting of the plate more stable.

[0018] When the sheet metal is hoisted above the base, the clamping assembly releases the hoisting rope, and the pushing assembly pushes the abutment plates closer together and pushes the rope clamp to the middle of the hoisting rod. The clamping assembly then clamps the hoisting rope again, the wedge block contacts the insertion rod and disengages the abutment plate from the pushing assembly. The pushing assembly brings the two clamping assemblies closer together, and the hoisting rod lowers to bring the sheet metal closer to the base. Then, the pushing assembly moves the two clamping assemblies further apart, and the sheet metal is lowered to facilitate its installation. Attached Figure Description

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-7 As shown, an aluminum sheet hoisting device includes a hoisting rod 1, a hoisting rope 2, fixed pulleys 3 installed at both ends of the hoisting rod 1, a clamping assembly 4, a rope clamp 5, an abutment plate 6 slidably disposed on the hoisting rod 1, a pushing assembly 7, an insert rod 8, and a wedge block 9.

[0029] When hoisting the sheet material, the connection point of the hoisting rope 2 to the sheet material is used. In practical applications, two hooks 21 can be connected to both ends of the hoisting rope 2. The hooks 21 are hung on the sheet material to lift it. Then, the hoisting device, such as a crane, is used to lift the hoisting rod 1. After the hoisting rope 2 is connected to the sheet material, the rope clamp 5 remains at the center of the hoisting rod 1 as the hoisting device rises. As the hoisting device rises, the hoisting rope 2 slides in the rope clamp 5 until the hoisting rope 2 is taut. At this point, the rope clamp 5 holds the hoisting rope 2. Then, the hoisting rod 1 is lifted by the hoisting device. At this time, during the hoisting, the rope clamp 5 clamps the hoisting rope 2. If the center of the plate shifts during the hoisting, the tension on the two hoisting ropes 2 will be different. During the hoisting process, the force on a single hoisting rope 2 may be too large, which may lead to danger. At this time, the hoisting rope 2 is clamped. Even if the center of gravity of the plate is not at the geometric center when the plate is hoisted, the hoisting rope 2 will not slide relative to the fixed pulley 3. That is to say, the plate will not deflect when it is hoisted, thus avoiding the plate being bumped.

[0030] The plate is then lifted to a certain height, and the rope clamp 5 releases the rope. The push assembly 7 is then moved, causing its movable end to move towards the two fixed pulleys 3. At this point, the abutment plate 6 slides towards the side of the plate's center until the plate's center of gravity is balanced. The movable end of the push assembly 7 continues to move towards the fixed pulleys 3 until it reaches both sides of the lifting rod 1. The rope is then clamped by the clamping assembly 4. At this point, the plate's center of gravity is stable, and the tension on the two lifting ropes 2 is essentially equal. The lifting device can then quickly lift the plate. During the lifting process, the plate's center of gravity remains stable, and the clamping assembly 4 prevents external factors such as wind from affecting the balance of the lifting ropes 2.

[0031] After the sheet metal is hoisted to the appropriate installation position, it needs to be aligned with the mounting holes on the base. At this time, the bottom of the sheet metal is not balanced. When hoisting the sheet metal close to the base, the push assembly 7 moves in the opposite direction, and the clamping assembly 4 releases its grip on the hoisting rope 2. The push assembly 7 pushes the two abutment plates 6 closer together. The closer proximity of the abutment plates 6 pushes the rope clamp 5 to the middle of the hoisting rod 1. At this time, the clamping assembly 4 clamps the hoisting rope 2 again. The insert rod 8 on the abutment plate 6 contacts the wedge block 9 and disengages the push assembly 7 from the abutment plate 6. The two movable ends of the push assembly 7... When they approach each other, the two clamping components 4 move closer together. That is, at this time, the bottom of the plate is horizontal and rises a certain distance. At this time, the operator operates the crane to bring the plate as close to the base as possible. Since the plate is far from the base when the operator operates the crane, the operator cannot accurately connect the mounting holes on the bottom of the plate with the mounting holes on the base. When the plate is close to the base, the operator on the base can operate the push component 7 to rotate, so that the clamping component 4 moves towards the fixed pulley 3 again. At this time, the plate is lowered, and the operator near the base can easily connect the plate to the base.

[0032] In a specific embodiment of the present invention, the hoisting rope 2 is a steel wire rope, and the rope clamp 5 is a KSQ type quick rope clamp with a clamping force of more than 20 tons, providing sufficient clamping force for the hoisting rope 2.

[0033] The pushing component 7 includes a drive motor 71, a gear 72, and two racks 73. The drive motor 71 is mounted on the hoisting rod 1, the gear 72 is mounted on the output end of the drive motor 71, and the two racks 73 are located on the upper and lower sides of the two gears 72, respectively. The movable end of the pushing component 7 is the two racks 73. The clamping component 4 and the abutment plate 6 are both mounted on the racks 73. The rotation of the drive motor 71 drives the gear 72 to rotate. The rotation of the gear 72 causes the two racks 73 to move in opposite directions, thereby causing the two abutment plates 6 to move closer to or further away from each other.

[0034] In a preferred embodiment of the present invention, the front and rear inner walls of the hoisting rod 1 are respectively provided with sliding grooves 74, and the two racks 73 slide in the front and rear sliding grooves 74 respectively.

[0035] The hoisting rod 1 is also equipped with a left-right sliding track, and the rope clamp 5 slides within the sliding track.

[0036] A buffer spring 10 is installed on the side of the abutment plate 6 near the rope clamp 5. When the rope clamp 5 releases its grip on the rope, the buffer spring 10 can provide a certain buffering effect to avoid excessive impact force on the abutment plate 6 by the rope clamp 5. When the two abutment plates 6 approach each other, the rope clamp 5 is pushed to the middle of the lifting rod 1. When the pushing component 7 pushes the abutment plates 6 closer together again to further compress the buffer spring 10, the wedge block 9 is inserted into the insertion rod 8, so that the abutment plate 6 is disengaged from the pushing component 7.

[0037] When the plate is heavy, the buffer spring 10 may not have enough compressible space when the rope clamp 5 is pushed to the middle of the lifting rod 1 by the abutment plate 6. Based on the above problem, in the second embodiment of the present invention, an electric telescopic rod (not shown in the figure) is provided on the wedge block 9. When the rope clamp 5 is pushed to the middle of the lifting rod 1, the electric telescopic rod drives the wedge block 9 to contact the insertion rod 8, thereby causing the abutment plate 6 to disengage from the pushing assembly 7.

[0038] A return spring 11 is provided between the insertion rod 8 and the abutment plate 6; when the wedge block 9 disengages from the insertion rod 8, the insertion rod 8 returns to its original position.

[0039] The clamping assembly 4 includes a base 41 with a downward-facing hydraulic rod 42 on it. A cavity adapted to the suspension rope 2 is formed between the ends of the base 41 and the hydraulic rod 42. When the end of the hydraulic rod 42 is close to the base 41, it clamps the rope.

[0040] Specific working principle:

[0041] When hoisting the sheet material, after the hoisting boom 1 rises and the hoisting rope 2 becomes taut, the rope clamp 5 clamps the hoisting rope 2. Then, the hoisting boom 1 rises a certain distance to lift the sheet material, which is then lifted horizontally to prevent the edges and corners from being bumped during hoisting. After the sheet material has been lifted a certain distance, the rope clamp 5 releases the hoisting rope 2, and the pushing component 7 drives the abutment plate 6 to slowly move towards the fixed pulley 3 until the abutment plate 6 disengages from the rope clamp 5. At this point, the clamping component 4 clamps the sheet material, and the tension on the hoisting rope 2 remains relatively constant. The hoisting process is more stable. When the plate is hoisted above the base, the clamping assembly 4 releases the hoisting rope 2, and the pushing assembly 7 pushes the abutment plate 6 closer together and pushes the rope clamp 5 to the middle of the hoisting rod 1. The clamping assembly 4 then clamps the hoisting rope 2 again, the wedge block 9 contacts the insertion rod 8 and the abutment plate 6 disengages from the pushing assembly 7. The pushing assembly 7 brings the two clamping assemblies 4 closer together, and then the hoisting rod 1 moves downward to bring the plate closer to the base. The pushing assembly 7 then moves the two clamping assemblies 4 further apart, and the plate is lowered to facilitate the installation of the plate.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
