Abstract
A traction device for large structure rolling shipment is provided with a plurality of chain shafts, a plurality of chain plates and a plurality of pairs of fasteners, wherein the chain plates are parallelly connected together in series and arranged at two ends of the chain shafts in series, and the chain plates and the chain shafts are fastened together through the fasteners, and the double-faced chain wheel traction device is formed by the connections. The traction device can accurately achieve movement on a projected route and safely transport large-structure objects to a ship in rolling mode. Meanwhile, the traction device can fit rolling traction in various working conditions, and can particularly and respectively achieve rolling of oversized and supergiant structure objects accurately and transport the oversized and supergiant structure objects to designated locations stably and reliably.
Description
Technical field
The utility model relates to draw gear, relates in particular to a kind of draw gear that is applicable to the large structure rolling shipment of using on the harbour.Belong to the ocean engineering 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, large structure such as supporting construction-jacket, single-point under water.After large structures such as chunk, jacket are built completion, need its shipment be transported, be placed in and specify in the marine site.
At present, most large structures are to load delivery onto ship through the mode of slippage, lifting.
Along with developing rapidly of ocean engineering construction; The increase of operating depth, the size of ocean structure and weight also constantly increase, and the works of several tons can be found everywhere; Maximization becomes a megatrend of development; Concentrate because piston shoes are stressed during the slippage shipment, sliding friction power also increases and linear the increase with works weight, thereby causes dilatory cost significantly to increase; And because structure stress concentrates, the shipment process is prone to produce that single leg is unsettled, local pressure and operating modes such as distortion is excessive, unbalance loading distortion.Simultaneously, because in traditional technics of shipment, its employed piston shoes do not have commonality, construction cost is higher.And the lifting mode is also lifted the lifting capabilities limits of weight-lifting equipment, also only is applicable to general large structure lifting.
The utility model content
The main purpose of the utility model is to overcome the shortcoming that prior art exists, and the draw gear that provides a kind of large structure to roll shipment, it can accomplish moving on the projected route accurately, with being rolled on the ship of large structure safety; Simultaneously, can adapt to the rolling traction under the various operating modes, particularly all can roll comparatively exactly, it is stablized the firm assigned address that is transported to ultra, super-huge works.
The purpose of the utility model is realized by following technical scheme:
The draw gear that a kind of large structure rolls and loads onto ship; It is characterized in that: be provided with several chain rivets, parallel that be cascaded and be installed in series at several carrier bars at chain rivet two ends, several fastener, through the above-mentioned two-sided sprocket wheel draw gear that connects and composes to being used for carrier bar and chain rivet are tightened together with several chain rivets.
Said fastener is spring washer and the clamp nut that is installed on the screw thread of chain rivet two ends.
The two ends up and down of said chain rivet are placed with guide plate respectively.
The beneficial effect of the utility model: the utility model is owing to adopt technique scheme, and it can accomplish moving on the projected route accurately, with being rolled on the ship of large structure safety; Simultaneously, can adapt to the rolling traction under the various operating modes, particularly all can roll comparatively exactly, it is stablized the firm assigned address that is transported to ultra, super-huge works.The utility model floor area is little, and in light weight, convenient transportation is for the weight-lifting equipment of its selection transportation has played key effect.
Description of drawings:
Fig. 1 looks scheme drawing for the utility model structure master.
Fig. 2 is the utility model structure schematic top plan view.
Fig. 3 is the utility model running condition scheme drawing.
Main label declaration among the figure:
The 1-chain rivet, the 2-carrier bar, the 3-spring washer, the 4-clamp nut, the 5-large structure,
The last guide plate of 6-, the 7-lower guide plate.
The specific embodiment
Like Fig. 1; Shown in Figure 2; The utility model mainly comprises: several chain rivets 1, be cascaded and be installed in series at several carrier bars 2 at chain rivet 1 two ends, several fastener to being used for carrier bar 2 and chain rivet 1 are tightened together several chain rivets 1 are parallel, present embodiment: fastener is spring washer 3 and clamp nut 4; The two ends of each chain rivet 1 are provided with screw thread, a carrier bar 2, a spring washer 3 and a clamp nut 4 respectively are installed, through the above-mentioned sprocket wheel draw gear that connects and composes on the chain rivet 1 two ends screw thread.
Principle of work: during use; On the sprocket wheel draw gear, reach the bottom and respectively place a guide plate 6,7; Draw on the guide plate 6 when moving when large structure 5 places, guide plate 6 carries out pure rolling and advances on one group of chain rivet 1, at this moment; The lower guide plate 7 that is positioned on the bottom also is that pure rolling contacts with this group chain rivet 1, realizes the mechanical type moving process.In the use, the sense of motion of large structure is controlled according to lower guide plate 7, and is simple and convenient; Can make up voluntarily according to on-the-spot actual conditions; And this device volume is little, in light weight, is convenient to carrying, and package unit moves comparatively convenient; Array configuration is many at the scene, is adapted to various operating mode and uses.
Above-mentioned chain rivet, carrier bar are the commercially available prod.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. the large structure draw gear of shipment that rolls; It is characterized in that: be provided with several chain rivets, parallel that be cascaded and be installed in series at several carrier bars at chain rivet two ends, several fastener, through the above-mentioned two-sided sprocket wheel draw gear that connects and composes to being used for carrier bar and chain rivet are tightened together with several chain rivets.
2. the draw gear that large structure according to claim 1 rolls and loads onto ship, it is characterized in that: said fastener is spring washer and the clamp nut that is installed on the screw thread of chain rivet two ends.
3. the draw gear that large structure according to claim 1 rolls and loads onto ship, it is characterized in that: the two ends up and down of said chain rivet are placed with guide plate respectively.
