The utility model relates to a hoisting lift cover which is characterized in that the hoisting lift cover comprises a first clamping device, a second clamping device and a connection tube, wherein the first clamping device and the second clamping device are used for connecting equipment to be hoisted, are symmetrically arranged and are adaptive to the equipment to be hoisted, lugs are arranged on both the first clamping device and the second clamping device, and two ends of the connection tube can be detachably inserted on two lugs in a penetrating way and are respectively welded with a lug cover plate, the diameter of the lug cover plate is larger than that of the connection tube. Compared with the prior art, the hoisting lift cover adopts the first clamping device and the second clamping device which are split, and the connection tube is hollow, therefore, the weight of the lift cover is greatly reduced, meanwhile, the number of the bolts which are used is reduced, the requirement to the crane specification is reduced, therefore, the hoisting is safer.
Description
Technical field
The utility model relates to the hanging device field, specifically refers to a kind of lifting lift cap.
Background technology
The lifting lift cap is widely used in the lifting of chemical plants such as reaction vessel as main hanger setting.Existing lifting lift cap generally includes and is used to connect the end cap of treating hanging device and the board-like hanger that is arranged on the end cap middle part; Said board-like hanger one end is arranged on the centre of end cap, and the other end is used for annexes such as joining shackle.This lift cap need adopt the technology manufacturing of solid forging, and manufacturing cost is higher.Chemical plant is all bigger usually on the other hand, causes the weight of lifting very big, and end cap normally is connected with flange on treating hanging device through bolt, and therefore connecting need be along the dense circle of arranging of the periphery of end cap and flange with bolt; Because the tie bolt consumption is many, simultaneously board-like hanger need be set, therefore in order to guarantee Joint strenght and safe in utilization, end cap must be solid.Will make that like this lifting lift cap weight is very big, manufacturing expense is high, also can influence selecting for use of crane simultaneously, increases lifting cost and uses.
Summary of the invention
The utility model technical matters to be solved is that the present situation to prior art provides a kind of in light weight, lifting lift cap that manufacturing expense is low.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this lifting lift cap is characterized in that comprising being used to connect first holding device and second holding device and the connection pipe of treating hanging device; Wherein, Described first holding device and second holding device be symmetrical set and with treat that hanging device is suitable; And be equipped with lug on first holding device and second holding device; Intert removedly on two lugs at the two ends of said connection pipe, and the two ends of connection pipe are respectively equipped with the hanger cover plate, and the diameter of hanger cover plate is greater than the diameter of said connection pipe.
Described first holding device comprises and is fitted in the inner splint treated on the hanging device inwall, is fitted in the external splint treated on the hanging device outer wall and both are linked together and are fitted in the connecting panel of treating on the hanging device end face; Said connecting panel is provided with screw, and said lug is arranged on described outer splice or the inner splint; The structure of said second holding device is identical with first holding device.
Lug on said first holding device and second holding device all has two, is separately positioned on described inner splint and the external splint.
Described lug is positioned at the middle part of said inner splint and external splint.
Evenly be provided with polylith on the said external splint and can external splint be positioned at the said fixture block of treating on the hanging device, each said fixture block protrudes to said inner splint direction.
Compared with prior art, the utility model adopts first holding device and second holding device of split, and connection pipe also is hollow, so the weight of this lift cap reduces significantly, has also reduced the consumption of bolt simultaneously; And lug is arranged on the middle part of two clamping plates, has improved stressing conditions, make that lifting is safer; And the design of the pipe that removably connects need not to connect other annex and can lift, and can realize automatic releasing hook simultaneously, has reduced aloft work; The design of clamp can be played the effect of location and insurance on the external splint, even when all bolt failures, clamp still can bear all lifting weight.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
This lifting lift cap comprises:
First holding device 1 comprises the arc inner splint 12 that is fitted on vessel flange 5 inwalls, is fitted in arc external splint 11 and connecting panel 13 on vessel flange 5 outer walls; Wherein, the middle part of inner splint 12 and external splint 11 is equipped with lug 14; The both sides of connecting panel 13 are welded on respectively on inner splint 12 and the external splint 11, thereunder form groove after the three-lane road welding is good.The bottom of external splint 11 is evenly equipped with a plurality of vertical draw-in grooves 15.Be respectively equipped with four screws 16 in two outsides of lug 14 on the connecting panel 13.
Second holding device 2, structure is identical with first holding device 1, during use, with first holding device, 1 symmetric arrangement.It comprises the arc inner splint 22 that is fitted on lifting flange 5 inwalls, is fitted in arc external splint 21 and connecting panel 23 on lifting flange 5 outer walls; Wherein, the middle part of inner splint 22 and external splint 21 is provided with lug 24; The both sides of connecting panel 23 are welded on respectively on inner splint 21 and the external splint 23, thereunder form groove after the three-lane road welding is good.The bottom of external splint 21 is evenly equipped with a plurality of vertical draw-in grooves 25.Be respectively equipped with four screws 26 in two outsides of lug 24 on the connecting panel 23.
Connection pipe 3 is connected with hoist cable when being used to lift, and is tubular shaft type, and its two ends are equipped with hanger cover plate 31.
Fixture block 4 is provided with corresponding to the draw-in groove on the external splint 11,21 15,25, each fixture block 4 pass respectively cooresponding draw-in groove and part evagination behind the inwall of external splint 11 with both weld togethers.
When using this lift cap to lift; External splint 11,21 is leaned against the outside of vessel flange 5; Inner splint 12,22 leans against the inboard of vessel flange 5, and connecting panel is positioned at the top of vessel flange 5, is about to vessel flange and is stuck in the groove; And screw on the connecting panel 13,23 and the alignment of the screw on the vessel flange connect with bolt 6 then.
Lift cap and vessel flange with bolt after, the flange of the upper end of clamp 4 and vessel flange 5 contacts, and clamp 4 and external splint 11,21 are welded.The effect of clamp 2 has two: the one, lift the location of lift cap, and the 2nd, play the effect of insurance, promptly under the situation that all bolts 6 all lost efficacy, clamp still can bear all weights of equipment.
The lifting lift cap that the utility model provided, in light weight, simple in structure, the lifting good stability, safe and reliable, reduced requirement simultaneously to the crane specification.
