Abstract
A large ocean structure dragging device comprises a winch and a plurality of pulley blocks, and is characterized in that a Z-type dragging point is arranged, the rear surface of the dragging point is pressed and fixed by a pressure block and the front surface is supported and fixed by a slide block, the winch is in certain distance with the dragging point and is arranged on the rear surface of the dragging point and fixed on ground, the ocean structure is in certain distance with the dragging point and is arranged on the front surface of the dragging point, the pulley blocks connected together are arranged between the ocean structure and the dragging point, one end of the pulley blocks is fixedly connected with the ocean structure and the other end is fixedly connected with the dragging point so that the winch is connected with the pulley blocks through wire rope so as to construct the large ocean structure dragging device. The utility model is not limited by the distance between two slide ways and the dragging point position can be adjusted; large ocean engineering structure can be dragged back by the dragging device; the large ocean structure dragging device has simple structure, saves steel material and is convenient for mounting and fixation.
Description
Technical field
The utility model relates to actuator, relates in particular to a kind of large ocean works back-dragging device, belongs to the marine oil engineering construction field.
Background technology
In the petroleum development engineering, need build various platforms such as oil production platform, accommodation platform, central processing platform at sea at sea.Platform general main comprising: ocean engineering chunk, ocean engineering structure such as supporting construction-jacket, single-point under water.The general elder generation of these ocean engineering structures carries out prefabricated by land, then, transports to marine assembling again.Usually, adopt the mode of lifting operation or dilatory slippage shipment with these ocean engineering structure shipments.
When the dilatory slippage of ocean engineering structure (as chunk, jacket etc.) is loaded onto ship, consider since the variation of marine tidal level, weather or in the process that dilatory slippage is gone on board dilatory apparatus problem has appearred, make under the situation that ocean structure can't go on board smoothly, sustain damage for fear of ocean structure, must possess a cover back-dragging device according to code requirement, prepare against back and drag, so that in time ocean structure is towed back to land.
As shown in Figure 1, existing back-dragging device mainly comprises: earth anchor 1, assembly pulley 2, piston shoes 3, crossbeam 4, winch 5, connection pulley 6.Fix on the ground two winches 5 with away from two assembly pulleys 2 of harbour, two other assembly pulley 2 ' is fixed on the crossbeam 4, crossbeam 4 is fixed on the piston shoes 3, then, winch 5 by steel rope and assembly pulley 2 be connected pulley 6 and link to each other and drag crossbeam 4 and piston shoes 3 back move, thereby make the works that places on the piston shoes 3 be towed back to land.
Because prefabricated by land works volume and weight was not very big in the past, ocean engineering structure adopts above-mentioned back-dragging device just can finish by conversion crossbeam and increase winch position when dilatory shipment.
Along with developing rapidly of ocean engineering construction, the volume and weight of ocean engineering structure is also in continuous increase, existing back-dragging device is because its crossbeam is to be fixed on two slide blocks, and directly horizontally be subjected to the restriction of distance between two slide blocks, if the length of crossbeam is less than the distance between two slideways at two slideway front ends, drag a position not adjust, therefore, existing back-dragging device can only drag at returning less than 6000 tons medium and small ocean structure, can not return the large ocean works and drag; And crossbeam itself weighs about 200 tons, and prefabricated cost is higher.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of large ocean works back-dragging device, its be not subjected to two spacing of slipway from restriction, can adjust dragging a position, realize the large ocean engineering structure returned and drag; It is simple in structure, has alleviated weight, is convenient to install and fix.
The purpose of this utility model is realized by following technical scheme.
A kind of large ocean works back-dragging device, comprise: winch, several assembly pulleys, it is characterized in that: the Z type that is provided with drags a little, drag a back to fix with the pressure block ballast, the front is fixed with slider support, described winch and this drag a little to keep at a certain distance away and place the back location that drags a little and fix with ground, ocean structure and this drag a little to keep at a certain distance away and place the anterior locations of dragging a little, between several assembly pulleys that link together are arranged on ocean structure and drag a little, one end of assembly pulley is fixedly connected on the ocean structure, the other end couples together winch and assembly pulley by steel rope on being fixedly connected on and dragging a little, constitutes large ocean works back-dragging device.
Described Z type drags the some steel structure for being welded by steel pipe or I-beam section.
The beneficial effects of the utility model: the utility model be not subjected to two spacing of slipway from restriction, can adjust dragging a position; Drag dot structure light, only 20 tons of weights can drag about 10000 tons works; Simple in structure, saved steel, and be convenient to install and fix.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Major label description in figure:
1 earth anchor, 2 assembly pulleys, 2 ' assembly pulley, 3 piston shoes, 4 crossbeams, 5 winches, 6 connection pulleys, 7 slide blocks, 8 pressure blocks, 9 drag point, 10 assembly pulleys, 10 ' assembly pulley, 11 ocean structures.
The specific embodiment
As shown in Figure 2, the utility model comprises: winch 5, several assembly pulleys 10, assembly pulley 10 ', the Z type that is provided with in back-dragging device drag a little 9, drag a little 9 to be Z font steel structures that are welded by steel pipe or I-beam section.Drag a little 9 back to fix with pressure block 8 ballasts, front slide block 7 support fixation, winch 5 drags a little 9 to keep at a certain distance away to place and drag a little 9 back location and fix with ground with this, ocean structure 11 drags a little 9 to keep at a certain distance away and place the anterior locations of dragging a little with this, several assembly pulleys that link together are arranged on ocean structure 11 and drag a little between 9 present embodiment: for two assembly pulleys that link together 10 and assembly pulley 10 ' are set.One end of assembly pulley 10 is fixed on the ocean structure 11, and the assembly pulley 10 ' other end is fixedly connected on and drags a little on 9, by steel rope winch 5, assembly pulley 10 and assembly pulley 10 ' is coupled together, and constitutes large ocean works back-dragging device.
During use, one group of identical large ocean works back-dragging device is installed respectively on the slideway of both sides, is started winch 5, winch 5 is started working, and is moving to travelling backwards by the rope belt running block, back moves thereby drive works 11.
Advantage of the present utility model:
1. having solved about 10000 ton large-scale ocean engineering structures draws back and drags.
2. drag a project organization reasonable, stressed even, save steel.
3. two are dragged that a little can to use spacing of slipway be 10 meters to 24 meters, even wideer spacing.
