Abstract

The utility model relates to a hoisting clamp for hoisting ocean platform H-shaped spud legs, particularly an accessory for hoisting objects, which is characterized in that two opening frameworks with the same shape and structure are connected into a closed quadrangular framework in an opening to opening mode, the middle parts of two borders, which are not used for connection, of the framework are oppositely provided with hanging lugs and each of the opening frameworks is in the shape of a U formed by that both ends of a long border are respectively connected with a short border vertically. In the hoisting clamp of the utility model, the two U-shaped frameworks with the same structure are oppositely connected into a quadrangular framework, and the quadrangular framework is tightly connected and buckled in a strip slot of an H-shaped spud leg, so that not only do the installation of the hoisting clamp and the hoisting of spud legs become convenient, but also the working procedures of the welding, the removal and the flaw detection of the procedure hanging lugs are eliminated. As a result, the labor cost and the time cost are saved and risk factors in highrise operation are avoided. Besides, because the U-shaped frameworks can be assembled and disassembled repeated for use, the material consumption is saved relatively.

Description

The stone tongs of lifting platform H type spud leg

Technical field

The utility model relates to the appurtenance that lifts object, is meant a kind of stone tongs that lifts by crane platform H type spud leg especially.

Background technology

Spud leg is the primary member of building in the platform, and commonly used having is cylindrical, square column type and triangular prism shaped, and its axial dimension is not only long, and structural weight is general all at hundred tons even more than hundreds of ton.Therefore, desire is more complicated with the hoisting that spud leg erects.Method commonly used is a welding process hanger on the member of lifting in advance, realizes and finish the lifting task of erectting spud leg according to this.After treating that the spud leg setting puts in place, again the technology hanger is excised.The weak point of this method is: the technology hanger is installed with the complex process and the work capacity of excision big; Hanger excision back is big to technical requirements height, the work capacity of the non-destructive flaw detection of member otch, and influences job schedule because of the restriction of the time code requirement of being detected a flaw; Secondly, the personnel of the different technical ability of the flaw detection operation of the excision of hanger and otch needs operate construction, and not only the potential safety hazard of aloft work is grown but also existed to the engineering time.In addition, for spud leg that lifts by crane the hundreds of tons of weight that weigh and the structural strength that guarantees job safety, choosing of technology hanger material and structure must have the dimensional characteristic that adapts with the member of lifting, and also established technology Lifting Lug Structure size is also bigger with the material weight that takies.Therefore, the hanger after the excision certainly will cause the waste of material.The spud leg that a kind of its section form commonly used is the square column type in the construction of platform is shaped on the chi bar of several outstanding spaces on four cylinders of this spud leg, the method for the lifting of this spud leg also is to adopt " technology hanger " method of above-mentioned interim welding.So, exist shortcoming and deficiency as hereinbefore so equally.

The utility model content

The purpose of this utility model, be for overcoming existing defective and deficiency in existing lifting overlength and the overweight H type spud leg construction operation, and a kind of stone tongs that lifts by crane platform H type spud leg is proposed, this stone tongs adopts following technical scheme: a kind of stone tongs that lifts by crane platform H type spud leg, comprise hanger, it is characterized in that two identical open framework counterparts of shape and structure are connected to the osed top quadrilateral frame, the middle part of two frames that this framework does not connect is equipped with hanger relatively; Open framework be a long margin frame two ends each vertical connect a minor face frame " [" shape, " two open ends of [" shape framework respectively are provided with connecting panel, and the edge of connecting panel is shaped on bolt hole; " [" shape framework long margin frame and two minor face frames are tetragonal pipe, and " long margin frame of [" shape framework is the vertical reinforced rib that is equipped with one or more in the tube wall up and down, and " at interval even is provided with some horizontal dividing plates in [" shape framework quadrangle pipe; Be that two minor face frames are being provided with a widened section near the inboard with the long margin frame coupling end.

Press the stone tongs that this programme is implemented, since have two structures identical " it is one " [] " shape framework that [" shape framework connects and composes relatively, " [] " shape framework leak-tight joint is buckled in the chi bar groove of H shape spud leg, the installation of these anchor clamps on spud leg and the lifting of spud leg had both been made things convenient for, the operations such as welding, excision and flaw detection of " technology hanger " have been exempted again, not only save manpower and time cost and avoided the danger factor in the aloft work, and because of " [" shape framework can load and unload repeatedly to use and save material consumption relatively.

The specific embodiment

Be further described in detail with regard to this embodiment in conjunction with the accompanying drawings.The utility model is an example with the H type spud leg 2 that lifts its surface and be equipped with chi bar 21; " [" shape framework 1 is made of long margin frame 11 and 12 welding of two minor face frames, long margin frame 11 and two minor face frames 12 are welded into tetragonal pipe by panels, the open end of minor face frame 12 is welded with connecting panel 13, and the suitable position of this panel edges is shaped on the hole 130 of tie bolt; Hanger 10 is welded in the middle part of long margin frame 11, and the two sides of hanger 10 can be welded with compound plate 101 respectively to gain in strength; " scantling of structure of [" shape framework has enough strength and stiffness except that assurance lifting spud leg 2 must possess, and the height that constitutes the pipe of framework also should be as the criterion to embed chi bar groove 20.For increase " strength and stiffness of [" shape framework, except that two of welding in the tube wall of long margin frame 11 about longitudinally the reinforced rib 123, the horizontal dividing plate 122 of even welding at interval in the pipe more also." [" shape framework should use in pairs, and promptly two " [" shape framework becomes " [] " shape in the chi bar groove that embeds the suitable position of lifting spud leg, the hole of passing connecting panel with bolt is " [] " shape framework of one with its leak-tight joint again.For the installation or removal of giving bolt stay the operations necessary space, " the minor face frame 12 of [" shape framework has a widened section 121 near the inboard of long margin frame 11 coupling ends, also be that four chi bar limits 21 of spud leg 2 have both sides to be overlapped on that " on the long margin frame 11 of [" shape framework, the both sides in addition of chi bar then have four arms of angle to be overlapped in " above [" shape framework minor face frame widened section 121.The utility model structure is simple and direct, reasonable, is a kind of effective and failure-free lifting accessory easy to use, safe.
