Embodiment Construction

[0039] For the convenience of description, the coordinate system is defined as figure 1 shown.

[0040] Such as figure 1 As shown, a hoisting device applied to indoor construction includes a chassis 1 on which a hoisting unit 3 and a hoist 2 are sequentially arranged from front to back. In order to facilitate the movement of the lifting device, four corners of the chassis 1 are respectively provided with rollers 11 .

[0041] Such as figure 1 As shown, the lifting unit 3 includes vertical beams 31 respectively arranged on the left and right sides of the chassis 1, and a cross beam 32 is arranged at the upper end of the vertical beams 31 between the two vertical beams 31, and The left and right ends of the crossbeam 32 are respectively fixedly connected with the vertical beam 31 by welding.

[0042] Such as figure 1 As shown, a first fixing sleeve 33 is arranged between the beam 32 and the chassis 1, and the upper and lower ends of the first fixing sleeve 33 are respective...

Abstract

The invention discloses a hoisting device for indoor construction. The hoisting device for indoor construction comprises a chassis, a hoisting unit, a winch and a fixing unit. The hoisting unit comprises a portal frame composed of vertical beams and a cross beam. A first fixed sleeve is arranged between the cross beam and the chassis. A sliding sleeve is arranged in the first fixed sleeve. A drivemechanism is arranged between the sliding sleeve and the portal frame. A supporting column is arranged in the sliding sleeve. The upper end of the supporting column is provided with a third pulley and a second pulley. The chassis is provided with a first pulley located between the winch and the hoisting unit. By the adoption of the hoisting device for indoor construction, extra arrangement of a hoisting point is not needed, the hoisting device assists in hoisting and installing a steel component and a pipeline, construction efficiency is high, the safety coefficient is high, and the flexibility and adaptability are high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a lifting device used in indoor construction. Background technique [0002] In the construction of buildings and mechanical and electrical installation projects, due to the construction characteristics, most construction manpower cannot directly move or lift, and the site environment lacks hanging points and lifting devices required for auxiliary installation. Generally, there are two methods used in the construction site: [0003] First, after welding temporary hanging structures (such as temporary lugs, temporary beams, etc.) on the original steel structure beams or embedded parts, then use chain hoists and other measures to assist in the installation. This method is greatly affected by the site environment, lacks flexibility, and often cannot meet the installation location. [0004] Second, re-build the hanging structure according to the installation location. ...
