Abstract
The utility model discloses a special sling, including the pipeline staple bolt, pipeline staple bolt top is equipped with rigid connection spare, and the rigid connection spare top is equipped with the triangle hoist, and triangle hoist top is equipped with the movable pulley, and the movable pulley top is equipped with the fixed pulley, and the fixed pulley rear side is connected with the crossbeam, and the crossbeam right side is equipped with electric block, and the electric block top is equipped with the fan, and the fan right side is equipped with the tuber pipe. The special sling reduces the shaking and inertia of the pipeline in the transportation process, greatly utilizes the existing operation space, meets the requirement of pipeline hoisting, provides reliable technical support for smooth implementation of pipeline installation in a long-distance small-caliber tunnel, greatly improves the operation efficiency and reduces the operation cost.
Description
Technical Field
The utility model belongs to the technical field of long defeated natural gas line installs, concretely relates to special lifting rope utensil.
Background
A natural gas pipeline is installed in a small-diameter tunnel, and due to the fact that construction is conducted in the tunnel which is long in distance, narrow in space and limited in operation height, how to guarantee hoisting and placing of the pipeline is achieved, and the completion of butt welding is a technical problem. Because not receive the restriction in operation space in the massif or the tunnel of crossing a river of heavy-calibre in the past, the form that traditional small-size planer-type hoisting hanger adopted wire rope electric block + lifting hook group can satisfy the installation needs, but at some in-process because the operation headroom is short, receives the influence of lifting by crane the clear distance, needs a neotype special sling of a section to solve above-mentioned problem, satisfies people's demand.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a special lifting rigging to solve its problem of lifting by crane height problem restriction, installation difficulty.
In order to achieve the above purpose, the utility model provides a following technical scheme: a special sling comprises
The pipeline staple bolt, pipeline staple bolt top is equipped with the rigid connection spare, the rigid connection spare top is equipped with the triangle hoist, triangle hoist top is equipped with the movable pulley, the movable pulley top is equipped with the fixed pulley, the fixed pulley rear side is connected with the crossbeam, the crossbeam right side is equipped with electric block, the electric block top is equipped with the fan, the fan right side is equipped with the tuber pipe.
Preferably, the fixed pulley is fixedly installed in the middle of the cross beam.
Preferably, the triangular lifting appliance, the rigid connecting piece and the pipeline hoop form a lifting fixture, and the lifting fixture is connected with the upper fixed pulley through a movable pulley.
Preferably, the electric hoist is fixed on the right side of the cross beam through a buckle in a welding mode.
Preferably, the fan is fixedly welded on the top of the inner wall of the pipeline through a support.
The utility model discloses a technological effect and advantage: this kind of special sling changes the direction of stress through increasing a fixed pulley in the middle of the crossbeam, move electric block to the right side of portal, clear space about the effectual utilization, simultaneously the pipeline staple bolt, the rigid connection spare, the hoist and mount fixture that the triangle-shaped hoist constitutes is connected with upper portion through a running block group, can be with the firm jam of pipeline like this, reduce rocking and inertia in the transportation, existing operation space has been greatly utilized, satisfy the demand of pipeline jack-up hoist and mount, the smooth implementation of pipeline installation in the long distance small-bore tunnel provides reliable technical guarantee, the operating efficiency is greatly improved, and the operation cost is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-pipeline hoop, 2-rigid connecting piece, 3-triangular lifting appliance, 4-movable pulley, 5-beam, 6-fixed pulley, 7-fan, 8-electric hoist and 9-air pipe.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a special sling as shown in figure 1, which comprises
Specifically, the fixed pulley 6 is fixedly installed in the middle of the cross beam 5.
Specifically, a lifting fixture is composed of a triangular lifting appliance 3, a rigid connecting piece 2 and a pipeline hoop 1, and is connected with an upper fixed pulley 6 through a movable pulley 4.
Specifically, the electric hoist 8 is fixed on the right side of the beam 5 by means of a buckle in a welding manner.
Specifically, the fan 7 is fixedly welded on the top of the inner wall of the pipeline through a support.
The working principle is as follows: the special sling improves a door type hoisting device in the using process, an electric hoist 8 originally arranged at the top of a beam 5 changes the stress direction by adding a fixed pulley 6 in the middle of the beam 5, the electric hoist 8 is moved to the right side of a portal frame, the upper and lower clean spaces are effectively utilized, a special hoisting clamp is manufactured and connected with the upper part through a movable pulley 4 group, the hoisting clamp consists of a pipeline hoop 1, a rigid connecting piece 2 and a triangular hoisting tool 3, the hoisting clamp is connected with the upper part through a movable pulley 4 group, therefore, the pipeline can be firmly clamped, the shaking and inertia in the transportation process are reduced, the existing operation space is greatly utilized, the requirement of pipeline hoisting is met, the reliable technical support is provided for the smooth implementation of pipeline installation in the long-distance small-caliber tunnel, the operation efficiency is greatly improved, and the operation cost is reduced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
