Description
Technical Field
The utility model belongs to the technical field of the high-speed railway bridge construction technique and specifically relates to a special lifting device of foldable special case roof beam of visitor is related to.
Background
In the construction of railway passenger transport lines, prefabricating and hoisting special box girders for passengers is an important work. According to the design scheme, the steel reinforcement cage of the special box girder for passengers is divided into a single line and a double line. In order to save the investment of hoisting equipment, the hoisting device is usually manufactured according to a double-wire reinforcement cage with a larger size. However, when the hanger is stored, the hanger occupies a large space and is not matched with a narrow prefabricated site, and the normal operation of other works of the prefabricated site is seriously influenced.
Disclosure of Invention
In order to satisfy the handling requirement of the special case roof beam of single double-line passenger, solve the great problem of steel reinforcement cage hoist volume simultaneously, the utility model provides a special lifting device of special case roof beam of foldable passenger who simple structure, facilitate the use and deposit specifically can adopt following technical scheme:
special foldable lifting appliance for passenger box girder, include
The hoisting truss comprises a steel truss consisting of a cross beam, a longitudinal beam and an oblique reinforcing rib, wherein a first hoisting piece for connecting hoisting equipment is arranged at the top of the steel truss, and a second hoisting piece for connecting a box girder steel reinforcement cage is arranged at the bottom of the steel truss;
folding hoist and mount arm, it includes a plurality of extension arms that set up on the longeron of both sides through the hinge mechanism, be provided with the third that is used for connecting the case roof beam steel reinforcement cage on the extension arm and hang the piece.
The first hanging piece is two groups of steel wire ropes symmetrically arranged on the top surface of the steel truss, each group of steel wire ropes is four, and the tops of the steel wire ropes are connected together.
The hinge mechanism comprises a first lug plate arranged at the top of the longitudinal beam and a second lug plate arranged at the top of the lengthened arm, and the tops of the first lug plate and the second lug plate are overlapped and hinged through a pin shaft.
The lengthened arms are correspondingly arranged on the outer side of each cross beam.
And the second hanging piece and the third hanging piece are both iron chains.
The utility model provides a special lifting device for folding passenger box girder, which has simple structure, firmness and stability and wide application range, and can adapt to the lifting of box girder steel reinforcement cages with different sizes by folding/extending the lengthening arm, thereby improving the utilization rate of the lifting device; simultaneously, can also fold extension arm when depositing and place to reduce the space occupation to the prefabricated place, improve the place utilization ratio.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1-3, the utility model discloses a special lifting device of foldable special case roof beam of visitor comprises hoist and mount truss and folding hoist and mount arm. The steel truss comprises a steel truss formed by welding a cross beam 1, a longitudinal beam 2 and an oblique reinforcing rib 3, wherein a first hanging piece used for connecting hoisting equipment is installed at the top of the steel truss, and a second hanging piece used for connecting a box girder steel reinforcement cage M is installed at the bottom of the steel truss; the latter includes a plurality of extension arms 4 that install on both sides longeron 2 through the hinge mechanism, all installs the third that is used for connecting box girder steel reinforcement cage M on every extension arm 4 and hangs the piece.
The cross beam 1, the longitudinal beam 2, the oblique reinforcing ribs 3 and the lengthened arms 4 are all made of I-shaped steel. Each steel truss is hoisted by two gantry cranes, so the first hoisting members are two groups of steel wire ropes 5 symmetrically arranged on the top surface of the steel truss. Each group of steel wire ropes 5 is four steel wire ropes with the same length, and the top parts of the steel wire ropes are connected together and then connected with a gantry crane. The hinging mechanism comprises a first lug plate 6 welded at the top of the longitudinal beam 1 and a second lug plate 7 welded at the top of the lengthened arm 4, and the tops of the first lug plate 6 and the second lug plate 7 are overlapped and hinged through a pin shaft 8. In order to strengthen the hoisting stability of the box girder steel reinforcement cage M, the lengthened arm 4 is correspondingly arranged on the outer side of each cross beam 1. The second hanging piece and the third hanging piece are both iron chains 9 which are convenient for binding the box girder steel reinforcement cage M.
During hoisting, whether the lengthened arm 4 is folded towards the inner side of the longitudinal beam 2 or not is selected according to the size of the box girder reinforcement cage M to be hoisted, then the box girder reinforcement cage M is bundled by the iron chain 9, the grouped steel wire ropes 5 are connected to the corresponding gantry cranes, and after the preparation work is finished, the box girder reinforcement cage M can be hoisted. After the hoisting work is finished, the lengthened arm 4 can be folded towards the inner side of the longitudinal beam 2 for storage in a folding mode.
