Description

Technical Field

[0002] Building wall panels are a new type of wall structure that integrates structural functions, decorative functions, and water and electricity professional practicality. They can be prefabricated in the factory and transported to the installation site for direct assembly, which improves work efficiency. When installing prefabricated building wall panels inside the building frame, it is usually necessary to use a lifting device to lift and transport the building wall panels to the installation site. The lifting device can reduce the intensity of manual transportation.

The driving plate 25 penetrates the through groove 29 and is slidably installed with the inner wall thereof. Square rods 26 are fixedly installed on the outer surfaces of the opposite sides of the driving plate 25. The two square rods 26 penetrate the outer surfaces of a group of two support plates 2202 and are slidably installed with them. The outer surfaces of the two square rods 26 are sleeved with second springs 28. One end of the second spring 28 is fixedly installed on the outer surface of the driving plate 25, and the other end of the second spring 28 is fixedly installed on the outer surface of the support plate 2202. A limiting ring 27 is fixedly installed on the outer surface of the square rod 26 close to the support plate 2202. The outer surfaces of the adjacent sides of the two mounting plates 11 are The surfaces are all fixedly installed with arc top blocks 30, and the outer surface of the arc top block 30 near the pressure cylinder 14 is provided with an oblique angle, the other end of the square rod 26 penetrates the end surface of the pressure cylinder 14 and abuts against the oblique angle of the arc top block 30, one end of the rotating shaft 22 penetrates the end surface of the pressure cylinder 14 and is fixedly installed with a baffle 2203, the outer surface of the rotating shaft 22 near the baffle 2203 is sleeved with a first spring 2204, the first spring 2204 is arranged between the baffle 2203 and the end surface of the pressure cylinder 14, the other end of the rotating shaft 22 penetrates the end surface of the pressure cylinder 14 and is rotatably installed with an arc limiting slider 2104, the outer surface of the other side of the arc limiting slider 2104 is fixedly installed with a clamping block 2103, and the outer surface of the support plate 15 on the side close to the arc limiting slider 2104 is penetrated with an arc groove 20,The inner wall of the arc groove 20 is fixedly mounted with an arc clamping plate 21, and the outer surface of the arc clamping plate 21 is penetrated with an arc waist groove 2105, and the arc limit slider 2104 is slidably mounted on the inner wall of the arc waist groove 2105. The outer surface of the arc clamping plate 21 away from the pressing cylinder 14 is alternately and equidistantly opened with high grooves 2101 and low grooves 2102, and the clamping block 2103 is against the inner walls of the high groove 2101 and the low groove 2102.

[0023] When the wire rope is wound from the end away from the circular arc clamping plate 21, the increase in the layer height of the wire rope drives the pressure cylinder 14 to move upward, and the pressure cylinder 14 drives the arc T-shaped slider 17 to slide along the arc T-shaped slide groove 16 through the connecting plate 1701. The upward movement of the pressure cylinder 14 drives the rotating shaft 22 to move upward, and the rotating shaft 22 drives the arc limiting slider 2104 to slide along the arc waist groove 2105. At this time, the clamping block 2103 slides to the inner wall of the high groove 2101 under the drive of the arc limiting slider 2104, and the clamping block 2103 pulls the rotating shaft 22 to move close to the circular arc clamping plate 21, so that it passes through the fixed wheel 2201, the support plate 2202 and the first spring 2204, driving one of the square rods 26 to move close to the circular arc clamping plate 21. When the pressure cylinder 14 rotates, it will drive the square rod 26 to move close to the circular arc clamping plate 21. The end of the square rod 26 is against the oblique angle of the arc top block 30, so that the square rod 26 drives the push bar 24 to move close to the direction of wire rope winding through the driving plate 25. The push bar 24 drives the strands of wire rope to resist each other through contact with the wire rope. When the pressure cylinder 14 rotates one end distance, the second spring 28 drives the square rod 26 to reset, and multiple square rods 26 move in sequence. When the wire rope changes direction and is wound, the pressure cylinder 14 will rise one layer, and the block 2103 will move to the position of the low groove 2102. When the wire rope is wound, the device can push adjacent strands of wire rope together to avoid irregular friction and impact between the strands of wire rope, reduce local wear of the wire rope, and extend the service life of the wire rope.

[0024] In this embodiment, the outer surfaces of the two mounting plates 11 that are away from each other are both rotatably mounted with rotating arms 18. The top ends of the two rotating arms 18 are respectively fixedly mounted to the outer surfaces of the other sides of the two arc T-shaped sliders 17. A torsion spring 19 is provided at the rotation center position of the rotating arms 18.

[0025] When the winch 12 is retrieving the steel wire rope, the torsion spring 19 and the rotating arm 18 drive the pressure cylinder 14 to abut against the surface of the steel wire rope, so that the push bar 24 abuts against the outer surface of the steel wire rope.

[0026] In this embodiment, vertical rods 2 are rotatably installed on the upper surfaces of the two bases 1, and a hexagonal hole 601 is opened at the top of the vertical rod 2. Two hexagonal columns 6 are symmetrically fixedly installed on the lower surface of the cross beam 4 near the two ends, and the hexagonal columns 6 are inserted into the hexagonal holes 601. Two connecting rods 3 are symmetrically hinged on the upper surface of the base 1, and the other ends of the two connecting rods 3 are hinged to the outer surface of the vertical rod 2. The two connecting rods 3 are symmetrically arranged on both sides of the vertical rod 2. A first drive motor 9 is fixedly installed on the upper surface of the slide 10, and a drive gear 8 is fixedly installed on the output end of the first drive motor 9. A rack 7 is fixedly installed on the upper surface of the cross beam 4, and the drive gear 8 is meshed with the rack 7.

[0027] The user hinges the base 1 and the vertical rod 2 together through pins, and then hinges the connecting rod 3, the base 1 and the vertical rod 2 together through pins, and finally assembles the crossbeam 4 together with the hexagonal hole 601 and the hexagonal column 6. This arrangement facilitates the rapid assembly of the lifting device. When the wire rope lifts the wall panel, the first driving motor 9 drives the driving gear 8 to rotate, and the driving gear 8 is engaged with the rack 7 to move the slide 10 along the crossbeam 4 to lift the wall panel to the specified position.

[0028] In this embodiment, a steel wire rope is wound around the outer surface of the winch 12, and a second drive motor 13 is fixedly installed on the outer surface of one side of one mounting plate 11, and the output end of the second drive motor 13 passes through the outer surface of the mounting plate 11 and is fixedly installed at the rotation center of the winch 12. Two limiting slide bars 1101 are symmetrically fixedly installed between the two mounting plates 11, and the two limiting slide bars 1101 are arranged under the winch 12. A slider 1102 is slidably installed on the outer surface of the two limiting slide bars 1101, and a through hole is penetrated on the outer surface of the slider 1102, and the other end of the steel wire rope passes through the through hole and is slidably installed on its inner wall.

[0029] The winch 12 is driven to rotate by the second driving motor 13, and the wire rope is recovered by the winch 12. The recovery of the wire rope is guided by the slider 1102 and the limiting slide bar 1101 to avoid large-scale shaking. There is sliding friction damping between the slider 1102 and the limiting slide bar 1101.

[0030] In this embodiment, the center of the arc T-shaped slide 16 is located at the rotation center of the rotating arm 18, the distance from the axis of the capstan 12 to the rotation center of the rotating arm 18 is equal to the rotation radius of the center line of the arc T-shaped slide 16, the arc top block 30 and the arc T-shaped slide 16 are located at the same center, the radius of the center line of the arc top block 30 is equal to the distance from the axis of the pressing cylinder 14 to the rotation center of the rotating arm 18, and the arc clamping plate 21 and the arc T-shaped slide 16 are located at the same center. This setting ensures that the clamping block 2103 can move correctly on the arc clamping plate 21.

[0031] In the present embodiment, it should be noted that the high groove 2101 and the low groove 2102 are provided with a height difference of a certain distance. When the wire rope is wound on the winch 12, it is wound layer by layer. Since the specifications of the wire rope are fixed, the layer height when the wire rope is wound is also fixed. The change of the winding direction of the wire rope causes the layer height to gradually overlap, so that the distance between the pressure cylinder 14 and the winch 12 increases layer by layer, thereby driving the block 2103 to slide alternately between the high groove 2101 and the low groove 2102. Through the position change of the block 2103, the two square rods 26 are pulled alternately to resist the oblique angle of the driving plate 25; the outer surface of the push strip 24 is provided with anti-slip stripes, and the push strip 24 slightly protrudes from the circumferential outer surface of the pressure cylinder 14; the elastic force of the first spring 2204 is greater than the second spring 28, ensuring that the push strip 24 will not drive the rotating shaft 22 to move when it slides.

[0032] It should be noted that when the present invention is used, the user hinges the base 1 and the vertical rod 2 with a pin, then hinges the connecting rod 3 with the base 1 and the vertical rod 2 with a pin, and finally assembles the crossbeam 4 with the hexagonal hole 601 and the hexagonal column 6 together. This arrangement facilitates the rapid assembly of the lifting device. Before use, the user fixes one end of the wire rope to the end of the winch 12 away from the arc clamping plate 21, drives the winch 12 to rotate through the second drive motor 13, and recycles the wire rope through the winch 12. When the winch 12 recycles the wire rope, the torsion spring 19 and the rotating arm 18 drive the pressure cylinder 14 to abut against the surface of the wire rope, so that the push bar 24 abuts against the outer surface of the wire rope. When the wire rope is wound on the winch 12, the rotation of the winch 12 drives the pressure cylinder 14 to rotate. When the wire rope is wound from the end away from the arc clamping plate 21, the wire rope is reeled in by the pressure cylinder 14. The increase in the layer height drives the pressure cylinder 14 to move upward, and the pressure cylinder 14 drives the arc T-shaped slider 17 to slide along the arc T-shaped slide groove 16 through the connecting plate 1701. The upward movement of the pressure cylinder 14 drives the rotating shaft 22 to move upward, and the rotating shaft 22 drives the arc limiting slider 2104 to slide along the arc waist groove 2105. At this time, the clamping block 2103 slides to the inner wall of the high groove 2101 under the drive of the arc limiting slider 2104, and the clamping block 2103 pulls the rotating shaft 22 to move close to the arc clamping plate 21, so that it passes through the fixed wheel 2201, the support plate 2202 and the first spring 2204, with When the pressing cylinder 14 rotates, the end of the square rod 26 is driven to abut against the oblique angle of the arc top block 30, so that the square rod 26 drives the push bar 24 to move close to the direction of the wire rope winding through the driving plate 25. The push bar 24 drives the wire ropes to abut against each other through the contact with the wire rope. When the pressing cylinder 14 rotates one end distance, the square rod 26 is reset through the second spring 28. Multiple square rods 26 move in sequence. When the wire rope changes direction to be wound, the pressing cylinder 14 will rise one layer, and the block 2103 will Move to the position of the low groove 2102. When the wire rope is wound up, the device can push adjacent strands of wire rope together to avoid irregular friction and impact between the strands of the wire rope, reduce local wear of the wire rope, and extend the service life of the wire rope. If the weight lifted by the wire rope is heavy, the torsion spring 19 can be replaced by a hydraulic telescopic rod. The telescopic end of the hydraulic telescopic rod is rotatably installed with the rotating arm 18, and the other end of the hydraulic telescopic rod is rotatably installed with the outer surface of the mounting plate 11, so that the pressure cylinder 14 has enough pressure to press the wire rope.
