Description

Technical Field

[0001] This utility model relates to a hoisting device, and more particularly to a hoisting device for construction sites. Background Technology

[0002] When working at heights, many scaffolding steel pipes and miscellaneous components need to be hoisted to the working surface. Generally, in order to save manpower, they need to be hoisted up. However, the open hoisting troughs, hanging nets, and tied hoisting methods currently used on construction sites are easy to overturn or fall when the wind is strong, which poses a great safety hazard.

[0003] Given the wide range of operational scenarios, it is necessary to provide a protective hoisting device with a wire rope net. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hoisting device for construction sites, which can safely and effectively fix steel pipes, scaffolding, steel bars and miscellaneous components when hoisting them on site, prevent them from falling off, and is easy to disassemble and operate.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a construction site hoisting device, including a vertical support frame formed by four vertical angle steels. Four horizontal connecting channel steels are provided in the middle of the four vertical angle steels to form a first horizontal support frame, and four horizontal connecting channel steels are provided at the bottom of the four vertical angle steels to form a second horizontal support frame. A hoisting wire rope is connected to the upper part of each vertical angle steel. A flexible wire rope net is provided outside the vertical support frame, the first horizontal support frame, and the second horizontal support frame. Connecting lifting rings are provided at the four corners of the flexible wire rope net, and the connecting lifting rings are connected to the hoisting wire ropes and hooks.

[0006] Furthermore, the mesh size of the flexible steel wire rope net is 20mm×20mm, and the dimensions of the flexible steel wire rope net after being laid flat are 3000mm×3000mm.

[0007] Furthermore, the grooves of the vertical angle steel face inward, the grooves of the horizontal connecting channel steel face outward, and the vertical angle steel and the horizontal connecting channel steel overlap, are fixed, and welded together at their intersection.

[0008] Furthermore, the hoisting wire rope is fixedly connected by passing through the hoisting connection hole on the vertical angle steel.

[0009] Furthermore, the bottom of the second transverse support frame is provided with three downward-facing bottom connecting channel steels.

[0010] Furthermore, the vertical angle steel is of type Q235B L150, the horizontal connecting channel steel is type Q235B 14# channel steel, and the bottom connecting channel steel is type Q235B 14# channel steel.

[0011] Compared with the prior art, the present invention has the following advantages: The construction site hoisting device provided by the present invention adopts a split structure design, with the outermost layer being supported by a wire mesh rope to prevent components, steel pipes and other materials from falling from the air, which is safe and reliable; moreover, it is easy to disassemble, recyclable, simple to operate, and saves time and labor.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Figure 1 This is a side view of the hoisting device for construction sites according to this utility model; Figure 2 This is a top view of the hoisting device for construction sites according to this utility model.

[0020] Please see Figure 1 and Figure 2 The construction site hoisting device provided by this utility model includes: a hook 1, a hoisting wire rope 2, a 3000mm×3000mm (mesh size: 20mm×20mm) flexible wire rope net 3, a hoisting connection hole 4, a vertical angle steel 5, a horizontal connecting channel steel 6, and a bottom connecting channel steel 7 and a connecting ring 8 at the bottom of the device; optionally, the vertical angle steel 5 is Q235B type L150 (5mm), the horizontal connecting channel steel 6 is Q235B type 14# channel steel, and the bottom connecting channel steel 7 is Q235B type 14# channel steel.

[0021] This utility model uses a flexible steel wire rope net 2 fixed to the bottom of a vertical angle steel 5. The flexible steel wire rope net 2 has connecting lifting rings 8 at its four corners. This net is used to prevent steel pipes and components from falling during the hoisting process.

[0022] This invention uses four inward-facing vertical angle steels 5 as the vertical frame support of the device. The four lateral supports are formed by welding and overlapping two sets of eight outward-facing horizontal connecting channel steels 6 to the vertical angle steels 5. Specifically, four horizontal connecting channel steels 6 are provided in the middle of the four vertical angle steels 5 to form a first lateral support frame, and four horizontal connecting channel steels 6 are provided at the bottom of the four vertical angle steels 5 to form a second lateral support frame. A hoisting wire rope 2 is connected to the upper part of each vertical angle steel 5. A flexible wire rope net 3 is provided outside the vertical support frame, the first lateral support frame, and the second lateral support frame.

[0023] The bottom of this invention uses a bottom connecting channel steel 7 with three downward-facing grooves, which is welded and overlapped with the horizontal connecting channel steel 6 for fixation. In addition, hoisting connection holes 4 need to be opened above the four vertical channel angle steels, and the hoisting wire rope 2 is passed through the hoisting connection holes 4 for fixed connection.

[0024] When using this utility model device for hoisting, the two connecting rings 8 on the same side are first hung on the hook 1, then the four steel wire ropes 2 are hung on the hook 1, and finally the two connecting rings on the other side are hung on the hook 1. After ensuring that the hook is securely and correctly hung, the hoisting work can be carried out.

[0025] Through the above specific embodiments, those skilled in the art can easily implement this utility model. However, it should be understood that this utility model is not limited to the above-described implementation methods. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.

[0026] Except for the technical features described in the specification, all others are known technologies to those skilled in the art.

[0027] This invention adds a flexible steel wire rope net 3 to the outside of the suspended platform. The four ends of the flexible steel wire rope net 3 have connecting lifting rings 8. During hoisting, the connecting lifting rings 8 are always suspended on the hooks 1. Therefore, even if strong winds overturn the components in the suspended platform, they will fall into the steel wire rope net and will not fall from a height, thus ensuring high safety. This invention adopts a split-structure design, which is simple to operate and convenient to use, and greatly improves safety compared to traditional hoisting methods.

[0028] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
