Description

Heavy-calibre concrete downspout lifting device

Technical Field

The utility model relates to a lifting device, especially a heavy-calibre concrete downspout lifting device.

Background

In the traditional concrete rainwater pipeline hoisting process, a rainwater pipe is generally hoisted into a pipe ditch by a crane after being wholly bound by a steel wire rope. Because some rainwater pipes have larger calibers, the steel wire ropes need to be matched by two persons in the binding process. After the rainwater pipe is hung in the pipe trench, the worker needs to manually unfasten the steel wire rope on the lifting hook of the crane, so that the labor and the time are wasted, and certain safety risks still exist in the construction of the operating personnel in the trench when the pipe trench is deep.

Disclosure of Invention

The utility model discloses a solve the technical problem who exists among the well-known technology and provide a heavy-calibre concrete downspout lifting device, this lifting device is simple to use, and hoist and mount are convenient, economize the manual work to can reduce safe risk.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: a large-diameter concrete rainwater pipe hoisting tool comprises a U-shaped suspender with a lateral opening, wherein an oblique-pulling suspender stiffening rib is respectively arranged on the upper side and the lower side of the inner side of the closed section of the U-shaped suspender, a lifting lug fixedly connected with the U-shaped suspender is arranged above the middle part of the U-shaped suspender, and a reinforcing structure is arranged between the lifting lug and the U-shaped suspender.

The U-shaped hanger rod is formed by welding three sections of H-shaped steel.

The stiffening rib of the cable-stayed suspender is made of H-shaped steel.

The lifting lug adopts a plate type structure, and lifting lug stiffening ribs fixedly connected with the U-shaped lifting rod are arranged on two sides of the lifting lug.

The utility model has the advantages and positive effects that: through adopting and inserting the rainwater pipe with side opening U type jib lower part pole, hang the mode of carrying out hoist and mount on U type jib with the rainwater pipe, can avoid binding directly of concrete pipe with wire rope to in the operating personnel need not go down the pipe chase of comparison dark, reduced the input of manpower, reduced wire rope and binded and disassembled the safe risk of in-process. Meanwhile, when the U-shaped suspender is used for hoisting the concrete rainwater pipeline, the levelness of the pipeline can be ensured, and the concrete rainwater pipeline is more convenient to install.

fig. 2 is a schematic view of the application of the present invention.

In the figure: 1. a U-shaped hanger rod; 2. a cable-stayed boom stiffening rib; 3. lifting lugs; 4. lifting lug stiffening ribs; 5. a wire rope; 6. A hook; 7. concrete downspout.

Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

referring to fig. 1 and 2, the heavy caliber concrete rain pipe hoisting tool comprises a U-shaped boom 1 with a lateral opening, wherein a diagonal boom stiffening rib 2 is respectively arranged above and below the inner side of the closed section of the U-shaped boom 1, and the reinforcing and anti-deformation effects are achieved for the boom. A lifting lug 3 fixedly connected with the U-shaped lifting rod 1 is arranged above the middle of the U-shaped lifting rod 1 and used for installing a lifting buckle and tying a steel wire rope, and a reinforcing structure is arranged between the lifting lug 3 and the U-shaped lifting rod 1 to reinforce the lifting lug and prevent the lifting lug from deforming in the lifting process.

In this embodiment, the U-shaped hanger rod 1 is formed by welding three sections of H-shaped steel, has strong bending resistance, simple construction, cost saving and light weight, can bear larger weight, and is convenient for meeting the requirement of hoisting a large-caliber rainwater pipe. In this embodiment, the cable-stayed boom stiffening rib 2 is made of H-shaped steel, the lifting lug 3 is of a plate-type structure, and lifting lug stiffening ribs 4 fixedly connected with the U-shaped boom are arranged on two sides of the lifting lug.

Before hoisting the rainwater pipe, the lifting lug 3 on the U-shaped suspender 1 is effectively connected with the lifting hook 6 on the crane by adopting the steel wire rope 5 and the buckle. Then the crane lifts the U-shaped suspender 1 and then penetrates the lower half part of the U-shaped suspender into the concrete rainwater pipe 7 to be lifted, the rainwater pipe is lifted by utilizing the lower part rod of the U-shaped suspender and is placed into the pipe trench, and the rainwater pipe is horizontally moved and directly penetrates into the rainwater pipe which is installed in place in the pipe trench. The installation speed of the large-caliber concrete rainwater pipe can be improved through the tool, and operators do not need to go down to a deeper pipe ditch, so that the safety risk is reduced.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
