Abstract

The utility model discloses a rocket launching arrangement structure. The rocket launching arrangement structure comprises a tunnel anchor, a main windlass, a No.1 tower, a Phi 16 steel wire rope, a Phi 14 soft rope, a rocket launching rack, a Phi 10 steel wire rope, a No.2 tower, an auxiliary windlass and a gravity anchor; the specification of the main windlass is 20 T, and the main windlass is placed beside the tunnel anchor; the No.1 tower is placed on one side of the main windlass and connected with the Phi 16 steel wire rope; the No.2 tower is placed on the opposite side of the No.1 tower and connected with the Phi 10 steel wire rope; the specification of the auxiliary windlass is 18 T, and the auxiliary windlass is placed on one side of the No.2 tower; the gravity anchor is arranged beside the auxiliary windlass; and the rocket launching rack is placed beside the No.2 tower and connected with the No.1 tower through the Phi 14 soft rope. The arrangement structure has the advantages as follows: the erection work of a suspension bridge leading rope is accelerated, is less subject to weather, terrain or ground feature, can avoid safety threat to working personnel or structures, and is less damaging to environment.

Description

A kind of rocket launching arrangement

Technical field

The utility model relates to an arrangement, particularly relates to a kind of rocket launching arrangement that large-span suspension bridge elder generation dragline sets up that is used for.

Background technology

The various main lines that are communicated with the mountain area need be crossed over valley, various gully, need build suspension bridge, and first dragline sets up the operation at first as the construction of suspension bridge superstructure, is the technical barrier that need break through.Generally, suspension bridge is built on the valley, gully, and the first dragline of little span mountain area suspension bridge generally is to adopt the mode that manually pulls to construct under the cooperation of hoist engine; Large-span suspension bridge is built usually on the waters of the dark wealthy complexity of mountain area river width of peak height paddy, and in this case, the erection method of first dragline comprises the method that manually pulls and helicopter traction method.

Wherein, the shortcoming that manually pulls method is:

1. construction risk is big, very easily causes security incident;

2. owing to the mountain area dense vegetation, the horizontal projection line usefulness after need setting up along first dragline in the steep hills paddy is manually cut out the passage of a wide 1.5m, and environmental destruction is very big;

3. be subjected to seasonal effect bigger, need avoid sleety weather and greasy weather;

4. construction period is longer, does not satisfy construction period.

The shortcoming of helicopter traction method is:

1. the turbulent property of mountain area bridge location is not only determined by the atmospheric boundary layer motion, and is subjected to the effect that the feature turbulent flow is streamed on the mountain peak, and is totally unfavorable to the flight safety influence;

2. the mountain area bridge location has certain influence to the visual field of flight;

3. the many weight in wet bases of mountain area bridge site zone mist have certain influence to the flight visual field;

4. two sides all will have one greater than 500m ²The place for helicopter landing, need build disposable lifting place, big to environmental disruption.

Therefore, need improve job practices.

The utility model content

The utility model aims to provide a kind of safe, economical, convenient, efficient, and the rocket launching arrangement that can use in large-span suspension bridge elder generation dragline sets up.

The technical scheme of a kind of rocket launching arrangement of the utility model is as follows:

A kind of rocket launching arrangement of the utility model comprises tunnel anchor, main winch, 1# tower, Φ 16 wire rope, Φ 14 soft ropes, rocket pod, Φ 10 wire rope, 2# tower, secondary hoist engine and gravity anchor; Described main winch specification is 20T, place anchor next door, tunnel, described 1# tower places a side of main winch, connects Φ 16 wire rope on the described 1# tower, and described 2# tower places the offside of 1# tower, connect Φ 10 wire rope on the described 2# tower, described secondary hoist engine specification is 18T, places a side of 2# tower, and described gravity anchor places secondary hoist engine next door, described rocket launching is placed on 2# tower next door, and described rocket pod is connected by Φ 14 soft ropes with the 1# tower.

The beneficial effect of a kind of rocket launching arrangement of the utility model is:

When a kind of rocket launching arrangement of the utility model is used for large-span suspension bridge elder generation dragline and sets up, can realize that rocket throws the rope technology, use this technology, the effect of acquisition comprises:

1. speed of application is fast;

2. be subjected to weather, the topography and geomorphology influence degree is little;

3. the operation person and works are not constituted security threat;

4. little to environmental disruption.
