Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] like figure 1 and figure 2 As shown, it is a steel beam cantilever erecting multifunctional movable protective underframe of the present invention, comprising a steel pipe protective frame body 1, a sliding beam 2 is arranged on the steel pipe protective frame body 1, the steel pipe protective frame body 1 and the lower chord of the steel truss girder The rod 6 is connected through the front hanging point 3, and the steel pipe protective frame body 1 is connected with the maintenance road longitudinal beam 5 through the rear hanging point 4. Sliding beam 2 is placed on the slide plate 302 of front hanging point 3, smear lubricating oil on the slide plate 302, when the position is fixed, slide beam 2 and front hanging point 3 are fixed with bolts. The steel pipe protective frame body 1 is welded to the rear hanging point 4, and is supported on the lo...

Abstract

The invention discloses a multifunctional movable protective underframe for steel beam cantilever erection. The multifunctional movable protective underframe comprises a steel pipe protective frame body provided with a sliding beam, the steel pipe protective frame body is connected with a steel truss girder lower chord member through a front suspension centre, and the steel pipe protective frame body is connected with a maintaining roadway longitudinal beam through a rear suspension centre. The multifunctional movable protective underframe is a safe and efficient construction safety protective device. The multifunctional movable protective underframe not only can provide a larger safety protective area and an operation platform, but also can move forward along with continuous forward erection of steel beams. The multifunctional movable protective underframe overcomes the defects that a safety protective net is hung on steel truss girder chord members normally when the steel beams are erected and installed, steel pipe frames are put up to expand the protective area and the operation platform, and the steel pipe frames need putting up and the safety net needs hanging every time the steel beams are erected and move forwards.

Description

technical field [0001] The invention relates to a multifunctional operating platform and construction safety protection technology for bridge erection facilities, in particular to an operating platform and safety protection support for steel truss girder cantilever erection. Background technique [0002] With the development of steel truss girder bridges at home and abroad, the safety requirements for construction are getting higher and higher, especially for the safety protection of steel truss girder cantilever erection. , The work efficiency is low, and it cannot provide an operating platform when the high bolt of the lower chord is screwed. It is necessary to install an additional operating platform and expand the protective area by assembling steel pipe protective frames. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a multifunctional movable protective underframe for cantilever erection o...
