Description

A transport frock that is arranged in shield tunnel box culvert to transport perpendicularly

Technical Field

The utility model belongs to transportation frock field especially relates to the hoist device that will well box culvert hoist transportation perpendicularly when shield tunnel is under construction, specifically is a transport frock that is arranged in shield tunnel box culvert transportation perpendicularly.

Background

In shield tunnels, box culverts can be used for drainage and as supports for secondary lining. The box culvert is mostly prefabricated, needs hoist and mount transportation on the scene. For the hoop connection face up in the box culvert transportation, traditional method uses lug and wire rope collocation to unload the box culvert to ground and deposits the district, and this kind of method needs artifical location, wastes time and energy, and handling in-process box culvert easily produces and rocks, has certain risk, can collide with box culvert edge, influences shaping structure outward appearance and safety, increases construction cost, reduces the efficiency of construction.

SUMMERY OF THE UTILITY MODEL

Problem to the transportation of box culvert vertical hoisting among the current shield tunnel, the utility model provides a transport frock for box culvert vertical hoisting among the shield tunnel.

The concrete structure is as follows: two same main beams are arranged horizontally and in parallel, the main beams are fixedly connected through a plurality of cross beams, and a plurality of lifting lugs are arranged above each main beam. The two ends of the main beam are provided with U-shaped clamps, and each U-shaped clamp comprises a first clamp vertically fixed at the end part of the main beam and a second clamp vertically fixed below the main beam; and matched bolt holes are formed in the lower ends of the first clamp and the second clamp.

Further, 3 crossbeams are evenly distributed.

Furthermore, a triangular supporting plate is arranged on one side of the second clamp close to the center of the main beam.

Furthermore, the lower ends of the first clamp and the second clamp are flush.

Further, every girder goes up the symmetry and sets up 2 lugs, 4 in total.

The utility model has the advantages of:

the utility model discloses simple structure, easily operation. Simultaneously, through the U-shaped clamp and the bolt holes, the hoisting process is safer and more stable.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A transport frock concrete structure that is arranged in shield tunnel box culvert to transport perpendicularly does: two same main beams 2 are horizontally and parallelly arranged, the main beams 2 are fixedly connected through a plurality of cross beams 6, and lifting lugs 1 are symmetrically arranged above each main beam 2 for 4 in total. Two ends of the main beam 2 are provided with U-shaped clamps capable of clamping two side walls of the box culvert, and each U-shaped clamp comprises a first clamp 3 vertically fixed at the end part of the main beam 2 and a second clamp 5 vertically fixed below the main beam 2. As shown in fig. 2 and 4, the lower ends of the first clamp 3 and the second clamp 5 are provided with matched bolt holes 7. Available bolt passes bolt hole 7 and the bolt hole of box culvert lateral wall, will transport the frock and be connected fixedly with the box culvert lateral wall.

Further, as shown in fig. 3, the number of the beams 6 is 3 and the beams are uniformly distributed.

Furthermore, as shown in fig. 1, a triangular support plate 4 is arranged on one side of the second clamp 5 close to the center of the main beam 2. The stability of the second clamp 5 is ensured.

Further, the lower ends of the first clamp 3 and the second clamp 5 are flush.

The working process is as follows: when hoisting the box culvert, firstly, the transfer tool is hoisted through the lifting lugs 1 to be aligned with the box culvert, the U-shaped clamps on two sides clamp the side wall of the box culvert, bolts sequentially pass through the bolt holes 7 on the first clamp 3, the bolt holes on the side wall of the box culvert and the bolt holes 7 on the second clamp 5 and are screwed up, and then the position of the box culvert is fixed, so that the transfer tool and the box culvert are connected into a whole, and the firmness can be ensured. And then hoisting the box culvert, moving to a storage position, and repeating the operation. The time consumed by manual positioning is reduced, the safety and stability of the hoisting process are ensured, and the damage to the box culvert structure is reduced. Simple structure, easy to understand method of use and low cost.
