Technical Field

[0001] The invention belongs to the technical field of enclosure plates, and in particular relates to a gravity-type hoisting device for steel structure enclosure plates. Background Art

[0002] The use of enclosure panels is very popular on construction sites. At the same time, panels are often used in other fields to enclose steel structures or other equipment. This type of enclosure panel is generally large in size and difficult to carry, so tower cranes and other lifting equipment are often needed to lift the panels. However, most of the existing lifting equipment has a simple structure and only uses a hook and a rope for binding and fixing. During the lifting process, there are safety hazards such as the panels falling off. On the other hand, it is troublesome to tie them during lifting, which affects work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a gravity lifting device for steel structure enclosure panels, which has a simple structure, easy operation, convenient adjustment, improved work efficiency, safety and stability, and a wide range of applications, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gravity-type lifting device for steel structure enclosure panels, comprising two groups of vertical rods, a connecting rod welded to the top end of one side of the vertical rod, and the two groups of connecting rods are cross-hinged by limit pins, and limit plates are installed on both sides of the connecting rods through limit pins, and mounting holes are provided at the connection between the connecting rods and the limit pins and at the top end of the connecting rods, fixing columns are welded to the front and back faces of the vertical rods, and elastic ropes are movably installed on the fixing columns, and a shock-absorbing spring is fixed to the side of the vertical rod at the bottom end of the connecting rod. The end of the shock-absorbing spring is fixed with a baffle, the bottom end of the baffle is welded with an insertion rod that passes through the vertical rod, and the surface of the insertion rod is located between the vertical rod and the baffle and is also sleeved with a return spring. A cross bar is fixed to the bottom of the vertical rod, and a splint is provided on one side of the cross bar. One side of the cross bar is provided with a slide groove at both ends of the splint, and a slider is slidably connected to the inside of the slide groove. A splint is also fixed to the surface of the slider, and the two ends of the other side of the cross bar are threadedly connected with fastening bolts whose ends are against the slider. The two ends of the bottom of the cross bar are fixed with hanging rings, and a bandage is hung on the hanging rings.

[0005] Preferably, a limiting groove with an arc chamfered end is provided at the connection between the limiting plate and the limiting pin, and at least three groups of fixing columns are provided at equal intervals from top to bottom.

[0006] Preferably, a protrusion is provided at the end of the insertion rod, and an elliptical through hole is provided at the connection between the vertical rod and the insertion rod.

[0007] Preferably, the surface of the clamping plate is wavy, and rubber gaskets are pasted on the surfaces of the clamping plate and the baffle.

[0008] Preferably, the slide groove and the slider are both convex-shaped with wear-resistant gaskets, and threaded holes are provided at the connection between the cross bar and the fastening bolts.

[0009] Preferably, an elastic component is provided on the surface of the bandage, and hooks matching with the hanging rings are provided at both ends of the bandage.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The cross-arranged connecting rods can make the two sets of vertical rods approach each other according to the action of gravity when the two sets of connecting rods are lifted by wire ropes, so that the clamping plates on the cross rods can clamp the enclosure panels. The limit plates with limit slots can effectively limit the cross angle between the two sets of connecting rods, thereby controlling the distance between the two sets of vertical rods and preventing the deformation of the enclosure panels due to excessive clamping force of the cross rods and vertical rods on the enclosure panels when the gravity is too large.

[0012] 2. The baffle at the end of the shock-absorbing spring can assist in clamping the maintenance plate and prevent the upper maintenance plate from shaking during lifting. Combined with multiple sets of fixed columns and elastic ropes, the surrounding of the enclosure plate can be effectively restricted and tightened to prevent the enclosure plate from tilting and falling during lifting;

[0013] 3. The splints on the crossbar and the slider can be used to stably hold the maintenance plates, making it convenient to lift the plates. At the same time, the position of the slider on the crossbar can be adjusted. The slider is fixed by tightening the bolts, thereby extending the length of the crossbar and clamping maintenance plates of different lengths. The bandages on the lifting rings can further play a safety protection role to prevent the lowest layer of protective plates from falling during the lifting process.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention provides Figure 1-3 The gravity-type lifting device for steel structure enclosure panels shown in the figure comprises two groups of vertical rods 1, a connecting rod 2 is welded to the top of one side of the vertical rod 1, and the two groups of connecting rods 2 are cross-hinged by limit pins 3, and limit plates 5 are also installed on both sides of the connecting rod 2 through the limit pins 3, and mounting holes 4 are provided at the connection between the connecting rod 2 and the limit pin 3 and the top of the connecting rod 2, the front and back faces of the vertical rod 1 are welded with fixing columns 7, and an elastic rope 8 is movably installed on the fixing column 7, a shock-absorbing spring 9 is fixed to the side of the vertical rod 1 at the bottom end of the connecting rod 2, and a baffle 10 is fixed to the end of the shock-absorbing spring 9, and the baffle 10 The bottom end is welded with an insertion rod 11 that passes through the vertical rod 1, and the surface of the insertion rod 11 is located between the vertical rod 1 and the baffle 10 and is also sleeved with a return spring 12. A cross bar 14 is fixed to the bottom of the vertical rod 1, and a splint 15 is provided on one side of the cross bar 14. One side of the cross bar 14 is located at both ends of the splint 15 and a slide groove 16 is provided, and a slider 17 is slidably connected inside the slide groove 16. The surface of the slider 17 is also fixed with a splint 15. The other two ends of the cross bar 14 are threadedly connected with fastening bolts 19 whose ends are against the slider 17. The bottom two ends of the cross bar 14 are fixed with rings 20, and a bandage 21 is hung on the rings 20.

[0020] Specifically, a limiting groove 6 with an arc-shaped chamfered end is provided at the connection between the limiting plate 5 and the limiting pin 3. At least three groups of fixing posts 7 are provided at equal intervals from top to bottom. The setting of the limiting groove 6 effectively limits the intersection angle between the two groups of connecting rods 2, thereby controlling the spacing between the two groups of vertical rods 1. The multiple groups of fixing posts 7, combined with the elastic rope 8, can effectively restrict and tighten the surrounding of the enclosure plate, preventing the enclosure plate from tilting and falling during lifting.

[0021] Preferably, a protrusion is provided at the end of the insertion rod 11, and an elliptical through-hole 13 is provided at the connection between the vertical rod 1 and the insertion rod 11. The provision of the protrusion can prevent one end of the insertion rod 11 from being pulled out of the through-hole 13, which would cause the baffle 10 to lose its auxiliary clamping function. The elliptical through-hole 13 can support the baffle 10 to tilt, thereby ensuring that the baffle 10 can better assist in clamping the enclosure panel.

[0022] Preferably, the surface of the clamping plate 15 is wavy, and rubber gaskets are attached to the surfaces of the clamping plate 15 and the baffle 10. The wavy clamping plate 15 with rubber gaskets can effectively clamp the maintenance plate, increase the friction between the maintenance plate and the surrounding plate, and ensure the stability of the clamping.

[0023] Preferably, the chute 16 and the slider 17 are both convex-shaped with wear-resistant gaskets, and a threaded hole 18 is provided at the connection between the cross bar 14 and the fastening bolt 19. The convex-shaped chute 16 and the slider 17 can prevent the slider 17 from being separated from the chute 16, and the provision of the threaded hole 18 can facilitate the fastening bolt 19 to fix the slider 17 to the cross bar 14.

[0024] Preferably, the surface of the bandage 21 is provided with an elastic component, and hooks that cooperate with the ring 20 are provided at both ends of the bandage 21. The elastic component can be used to adjust the length of the bandage 21, and the setting of the hook can facilitate the disassembly and assembly of the bandage 21 and the ring 20.

[0025] Working principle: When in use, first hang the top of the connecting rod 2 on the lifting equipment with a wire rope. When the plate needs to be lifted, first make the vertical rod 1 located on both sides of the plate. Then, when the lifting equipment drives the connecting rod 2 to rise, the two sets of vertical rods 1 will move closer to each other under the action of gravity, so that the splints 15 on the cross bar 14 can clamp the two sides of the enclosure plate. At the same time, the baffle 10 on the side of the vertical rod 1 can block the maintenance plate to prevent it from moving and tilting, and on the other hand, it can also play an auxiliary clamping role. Then, tie the two ends of the elastic rope 8 to the fixed columns 7 of the two sets of vertical rods 1 respectively to fix the maintenance plate. Finally, hang the two ends of the strap 21 on the lifting rings 20 at the bottom ends of the two sets of cross beams 14. At this time, the lifting equipment can be used to lift the enclosure plate.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
