Problems solved by technology

Compared with other types of station buildings, its design form makes full and reasonable use of land and space, but this design makes the construction space very narrow, which brings certain difficulties to traditional construction, resulting in conventional hydraulic pressure. The boom of the truck crane cannot be extended, and the lifting height of the hook head is insufficient, which makes the construction of the hydraulic truck crane impossible; if the overall sliding technology is used for construction, it is necessary to provide additional steel beam assembly sites, assembly brackets, sliding equipment, etc., which is not only time-consuming and consuming Force, material consumption, and ultimately affect the installation period

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] see Figure 1-3 As shown, the present invention is a lifting tool that is convenient for working in a narrow space area, including a load-bearing tool 1 and an electric hoist 2;

[0025] Here, the rated lifting capacity of the electric hoist 2 is 15t, and the electric hoist 2 is the prior art, and will not be described in detail in this technical solution;

[0026] The load-bearing tooling 1 includes two first columns 3, which are fixedly connected by conne...

Abstract

The invention discloses a lifting tool convenient to operate in a narrow space area, and relates to the technical field of large-span steel structure lifting construction equipment. The lifting tool comprises an electric hoister and further comprises a bearing tool, the bearing tool comprises two first stand columns, and the two first stand columns are fixedly connected through a connecting cross beam. According to the lifting tool, through cooperation of the bearing tool and the electric hoister, the problem that a hydraulic truck crane cannot carry out construction due to narrow construction site and insufficient operation space is solved, hoisting can be carried out under the conditions of the narrow construction site and the insufficient operation space, the consumption of manpower, materials, equipment and sites caused by using an integral sliding technology is greatly reduced, and the direct cost is greatly reduced; and all the components are made of conventional materials, are convenient to purchase, low in price, simple in manufacturing process and recyclable, no large-area construction site is needed, and the problem of difficult coordination with cross construction of civil engineering is solved.

Description

technical field [0001] The invention belongs to the technical field of lifting construction equipment for large-span steel structures, and in particular relates to a lifting tool that facilitates operations in narrow space areas. Background technique [0002] With the rapid development of my country's high-speed railway, as an important hub of the railway transportation network system - the high-speed railway passenger station building has also ushered in a new round of construction climax, and the under-line passenger station building has also emerged as the times require. That is to say, the station building is located directly under the viaduct of the railway line, and the flow line of passengers is in the form of upward flow and upward flow. Compared with other types of station buildings, its design form makes full and reasonable use of land and space, but this design makes the construction space very narrow, which brings certain difficulties to traditional construction, ...
