Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, and in particular to a lifting device that facilitates the hoisting of lightweight curtain wall materials. Background Technology

[0002] Currently, the installation of curtain walls for elevated stations or small buildings using truck cranes is costly, and the steel structure of station roofs does not allow for the installation of suspended platforms. Furthermore, due to the lightweight nature of curtain wall materials, the lifting capacity of hoisting equipment allows for the direct vertical transport of curtain wall stone and glass by suspending them on hooks. During transport, the curtain wall materials are susceptible to swaying due to external forces or wind direction, increasing safety risks. Utility Model Content

[0003] This utility model provides a lifting device that facilitates the hoisting of lightweight curtain wall materials to solve the technical problems existing in the prior art. The device has low cost, low operating cost and good safety.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: a lifting device for facilitating the hoisting of lightweight curtain wall materials, including a frame set on the roof, outriggers threadedly connected to the frame, outrigger discs at the lower ends of the outriggers, a vertical pole horizontally centered at the head of the frame, a winch installed at the tail, a lifting wire rope wound on the winch, a forward cantilever vertically fixed to the upper end of the vertical pole, fixed pulleys at both ends of the top of the forward cantilever and at the bottom of the cantilever end, a limiting sleeve below the bottom fixed pulley, the limiting sleeve being vertically set and connected to the vertical pole through a horizontal support rod vertically fixed to it, the lifting wire rope passing through the fixed pulleys and the limiting sleeve in sequence, a hanging plate on the lifting end of the lifting wire rope, and a hanging ring below the hanging plate.

[0005] Based on the above solution, the present invention has made the following improvements:

[0006] Protective sleeves are provided at both ends of the limiting sleeve.

[0007] A vertical guide groove is provided on the front side of the upright, and the connecting end of the horizontal support rod is located in the vertical guide groove. The two are slidably connected, and a limit switch is provided on the vertical guide groove.

[0008] The winch drum is equipped with a handle, which is secured by a safety pin.

[0009] Rollers are installed under the frame.

[0010] The upright is equipped with diagonal bracing on the rear side and both sides.

[0011] The frame is constructed by welding rectangular steel pipes.

[0012] The advantages and positive effects of this invention are as follows: By using a fixed pulley to guide the lifting wire rope and a limiting sleeve to limit the lifting wire rope, the stability of the lifting wire rope is enhanced, its sway amplitude is reduced, and thus the safety during hoisting is improved. Furthermore, the above-mentioned lifting equipment has a simple structure, uses readily available materials, and has low manufacturing and operating costs, thereby reducing the hoisting cost of curtain wall materials.

[0017] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0018] Please see Figures 1-3 A lifting device for facilitating the hoisting of lightweight curtain wall materials includes a frame 1 installed on the roof, with outriggers 2 threadedly connected to the frame 1, and outrigger discs 3 provided at the lower ends of the outriggers 2.

[0019] The frame 1 has a horizontally centered upright 4 at the head and a winch 5 at the tail, with a lifting wire rope 10 wound around the winch 5.

[0020] The upper end of the upright post 4 is provided with a forward cantilever 6 that is vertically fixed to it, and fixed pulleys 7 are provided at both ends of the top of the forward cantilever 6 and at the bottom of the cantilever end.

[0021] A limiting sleeve 8 is provided below the bottom fixed pulley. The limiting sleeve 8 is vertically arranged and connected to the upright 4 through a horizontal support rod 9 that is vertically fixed to it.

[0022] The lifting wire rope 10 passes sequentially around the fixed pulley 7 and through the limiting sleeve 8. A hanging plate 11 is provided on the lifting end of the lifting wire rope 10, and a hanging ring is provided below the hanging plate.

[0023] By using fixed pulleys to guide the lifting wire rope and using limiting sleeves to limit the lifting wire rope, the stability of the lifting wire rope is enhanced, its sway amplitude is reduced, and thus the safety during hoisting is improved. Furthermore, the aforementioned lifting equipment has a simple structure, uses readily available and low-cost materials, thereby reducing the hoisting cost of curtain wall materials.

[0024] The more preferred solution in this embodiment is as follows:

[0025] Protective sleeves 12 are provided at both ends of the limiting sleeve 8 to protect the hoisting wire rope from damage.

[0026] A vertical guide groove 13 is provided on the front side of the upright 4, and the connecting end of the horizontal support rod 9 is disposed in the vertical guide groove 13, and the two are slidably connected. A limit switch is provided on the vertical guide groove 13. When the hoisting height exceeds the limit, the horizontal support rod 9 and the limit sleeve 8 rise together with the hoisted object until the limit switch issues a stop signal. Therefore, this structure can protect the horizontal support rod 9 and the limit sleeve 8 from damage under abnormal operation.

[0027] The drum of the winch 5 is provided with a handle 14, which is fixed by a safety pin 15. In this embodiment, the safety pin 15 is fixed to the housing 16. This structure is used to stabilize the height of the lifting wire rope and prevent the winch from starting unexpectedly.

[0028] Rollers 17 are installed under the frame 1 to facilitate the movement of the equipment.

[0029] The upright 4 is provided with diagonal bracing 18 on the rear side and both sides to strengthen the structure.

[0030] The frame 1 is made of rectangular steel pipes welded together. The material is readily available, has high strength, and is low in cost.

[0031] How to use this utility model:

[0032] First, after moving the hoisting equipment to the working position, rotate the outrigger 2 to lower the outrigger plate 3 to support the roof. Then, release the hoisting wire rope 10, let it pass through each fixed pulley 7 and then through the limiting sleeve 8. Finally, fix the hanging plate 11 to the hoisting end of the hoisting wire rope.

[0033] During hoisting, at least two slings 19 are used to securely connect the curtain wall material 20 to the hanging plate 11. The winch 5 is started to wind up the lifting wire rope 10, which lifts the curtain wall material. During the hoisting process, due to the presence of the fixed pulley 7 and the limiting sleeve 8, the lifting wire rope 10 always moves in the vertical direction, which greatly reduces the sway of the curtain wall material 20 and better ensures the safety of the hoisting process.

[0034] Finally, once the curtain wall material 20 has risen to the set height, the winch 5 is shut down, the drum is secured with the safety pin 15, the hoisting equipment stops operating, and the handling begins. After the handling is completed, the safety pin 15 is pulled out, and the hoisting equipment resumes operation.

[0035] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
