Description
Technical field
The present invention relates to a kind of folding trestle, especially set up and remove the receipts trestle fast with mechanical system.
Background technology
During the offshore oil drilling operation, often need service fixed platform to be connected, be the drilling platform service with the drilling platform of fixing.When service platform is connected with drilling platform, need on two platforms, set up trestle, pass through for personnel and mini-plant, and at facilities such as trestle edge cable laying, fire lines.At present existing trestle mostly is integral truss-type, is transported to the overlap joint platform by freighter usually during installation, by the loop wheel machine on the platform overlapped points that trestle winches on the Platform Deck is set up again.When service platform is withdrawn, also need freighter to carry out middle transition, trestle is removed transported.The weak point of this trestle is to set up and removes that receipts speed is slow, complex operation, labour intensity are big, when meeting emergency, is difficult to finish rapidly at short notice remove receipts especially.
Summary of the invention
The objective of the invention is: provide a kind of quick, convenient, be fixed on the mechanically-actuated folding trestle on the fixed offshore platform, it have take up an area of little, labour intensity is low, easy to operate, can set up and remove characteristics such as receipts fast.
For achieving the above object, the invention provides a kind of mechanically-actuated folding trestle that is fixed on the fixed offshore platform, mainly partly be made up of pedestal, flatcar, walking mechanism, portal trestle, slew gear, winch, hydraulic system, electrical system etc., wherein hydraulic system, electrical system are formed the trestle control system.Trestle is fixed on the Platform Deck by pedestal, sets gradually members such as flatcar, walking mechanism, portal trestle, slew gear, winch, spanning above.
Pedestal is fixed on the fixed offshore platform.Pedestal is provided with slideway, flatcar and be installed in above it member by walking mechanism drive can be in slideway straight line come and go and move, can flatcar and top member thereof be moved to needed position according to two platform actual ranges during operation.Also be provided with the flatcar steady pin on the flatcar, behind the flatcar location, use fixedly flatcar of flatcar steady pin.
Portal trestle is installed in the flatcar top, connects with flatcar by a pivoting support.The portal trestle base is provided with slew gear, drives portal trestle and the 360 ° of rotations of level together of superincumbent member are installed.Be provided with winch on the portal trestle, can mention or put down spanning, what be used for trestle sets up and removes receipts, and can adjust spanning overlap joint angle in perpendicular.
Spanning is collapsible, can be made up of two bridges joint, three bridge joints or four bridges joints, is provided with hydraulic turnover mechanism between the bridge joint, is launched or the gathering spanning by hydraulic turnover mechanism during use.Spanning one end is hingedly fixed on the portal trestle, with portal trestle mutually the other end of crossover joint link to each other with winch cable.Spanning misalignment spanning pin joint is outside, and during the trestle operation, spanning can vertically rotate to an angle around pin joint on portal trestle under winch cable pulling force and self gravitation effect.The spanning other end is provided with universal rolling wheel, convenient and opposite bank platform overlap joint.Be provided with railing on the spanning, turning 90 ° fold and can load and unload.
The trestle control system can be controlled and can finish the trestle operation, and the trestle power source can utilize platform power, also can be by the self-powered equipment of trestle.
The present invention has the following advantages and effect: control system control the trestle operation, set up and remove receive fast, labour intensity is low, 1 people controls and can finish the trestle operation, can regulate overlap distance and angle etc.

The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in drawings, the present invention mainly partly is made up of pedestal 2, flatcar 4, walking mechanism 14, portal trestle 5, slew gear 18, winch 13, spanning 7, hydraulic system, electrical system etc., and wherein hydraulic system, electrical system are formed the trestle control system.The connection of whole trestle each several part and function are:
Pedestal 2 directly is fixed on fixed offshore platform 1 deck.Pedestal 2 is provided with slideway 3, and flatcar 4 is provided with roller 17, drives and can come and go mobile by straight line in slideway 3 by the walking mechanism 14 that is arranged between pedestal 2 and the flatcar 4.Can flatcar 4 and top member thereof be moved to needed lap position according to the actual range between two fixed offshore platforms 1,10 during operation.Also be provided with flatcar steady pin 16 on the flatcar 4, after flatcar 4 moves into place, flatcar 4 is fixing with flatcar steady pin 16.
Portal trestle 5 is a frame construction, is provided with above members such as spanning 7, slew gear 18, winch 13, wire rope pulley system 13 are installed.Portal trestle 5 is installed in flatcar 4 tops, and its bottom connects with flatcar 4 by pivoting support 15.Portal trestle 5 bottoms are provided with slew gear 18, and slew gear 18 can drive portal trestle 5 and top member 360 ° of rotations of level together thereof.During the trestle operation, can as required portal trestle 5 and top member thereof be horizontally rotated needed angle, then that portal trestle 5 is fixing.Winch 13 is fixed on the framework of portal trestle 5, and winch 13 is provided with wire rope 11, and wire rope 11 1 ends are fixed on the winch 13, and the other end passes and is fixed on the spanning 7 after the wire rope pulley system 12.During the trestle operation, utilize winch 13 folding and unfolding wire rope 11 with spanning 7 toward transfer or on carry, help spanning 7 to launch or draw in.Can or withdraw with opposite bank fixed offshore platform 10 overlap joints simultaneously, and can regulate the overlap joint angle of vertical direction.
Spanning 7 is collapsible, can be made up of 18, three bridges joints of two bridges joint or four bridges joints, is provided with hydraulic turnover mechanism 19 between the bridge joint 18, is launched or gathering by hydraulic turnover mechanism 19.Spanning 7 one ends are hingedly fixed on the portal trestle 5, and link to each other with the wire rope 11 of winch 13 with the other end that portal trestle 5 is hinged and connected bridge joint.It is outside that spanning 7 position of centre of gravitys 8 depart from spanning 7 pin joints 6, and during the trestle operation, spanning 7 can vertically rotate to an angle around pin joint 6 on portal trestle 5 under wire rope 11 pulling force and self gravitation effect.Spanning 7 other ends are provided with universal rolling wheel 20, convenient and opposite bank platform overlap joint.Be provided with railing 9 on the spanning 7, turning 90 ° fold and can load and unload.When spanning 7 is set up, earlier spanning 7 is launched, again railing 9 upsets are opened or loaded onto for 90 °; Spanning 7 is removed the time receiving, after earlier 90 ° of railing 9 upsets being folded or remove, bridge 7 is striden folding gathering the in again.
The trestle control system that hydraulic pressure and electrical system are formed is controlled each mechanism action, finishes the trestle operation.The trestle power source can be provided by fixed offshore platform 1, and also can wear power-equipment by trestle provides.
Erection process division of the present invention is as follows:
1, sets up preparation, connect power, remove trestle and fix, determine decorating position (as Fig. 4).
2, flatcar is moved to behind the decorating position fixingly, portal trestle is rotated to set up angle (as Fig. 5) then.
3, put winch cable, spanning is transferred to required angle (as Fig. 6).
4, spanning is launched (as Fig. 7).
5, put winch cable, spanning is transferred, with opposite bank platform overlap joint (as Fig. 8).
6, open or install spanning railing (as Fig. 9).
It is opposite substantially with erection process that the present invention removes the receipts process.
