Abstract
The invention relates to a clamp capable of being used for vertically hanging steel pipes. The clamp is provided with a plurality of arc plates, wherein the arc plates are connected into a sealed circular ring structure through a press tongue shaft arranged among the arc plates, a press tongue is pivoted on the press tongue shaft, the bottom force arm of the press tongue is a flat end, and a press tongue tooth extends from one end of the bottom force arm towards the upper edge. The clamp has the advantages that the self weight of the steel pipes can be used for enabling the press tongue of the clamp to freely and tightly press the steel pipes, and in addition, the vertical steel pipes can be hung up; after the steel pipes reach the proper position, when a slide rope is pulled by force, the self weight of the clamp can be used for releasing the press tongue, in addition, after the falling to the convenient-to-operate height along with the descending of a crane, a steel wire rope is hung in a hook, the clamp can be lifted, and release of a hanging machine is also realized. The problem that a hanging point needs to be welded and dismounted during the steel pipe hanging is solved; the materials are greatly saved, the hanging efficiency is improved, and the adverse influence caused on the steel pipes is avoided.
Description
Technical field
The present invention relates to hanging apparatus, particularly relate to a kind of clamp that vertically can lift steel pipe.Belong to Offshore Engineering field.
Background technology
At present, the normally used steel pipe post diameter of ocean steel construction type platform is: the pipe of 406mm, 508mm, 610mm, 762mm and 914mm, and it generally adopts and lift in the method for steel pipe upper end welding suspension centre when mounted.Owing to needing to weld suspension centre during lifting, after lifting, must suspension centre be dismantled again, therefore, not only waste steel plate and wlding, and, turn increase construction intensity and duration, also can produce negatively influencing to the material property of steel pipe.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and provides a kind of clamp that vertically can lift steel pipe, and it can not only utilize steel pipe deadweight to make clamp press tongue freely to compress steel pipe, and vertical steel pipe can be sling; After steel pipe is in place, pull at slip rope time, pressure tongue can be unclamped by the deadweight of clamp, and transferring and after droping to the height of convenient operation, hung over by steel rope in hook, can clamp be promoted, achieve again the releasing to loop wheel machine with hoisting crane; When solving lifting steel pipes, need the problem of welding, dismantling suspension centre; Greatly realize saving material, improve lifting efficiency, avoid causing negatively influencing to steel pipe.
The object of the invention is to be realized by following technical scheme:
Vertically can lift a clamp for steel pipe, it is characterized in that: be provided with: several piece arc plate, by the pressure tongue axle be arranged between several piece arc plate, several piece arc plate be connected into a closed circular ring structure; Wherein, press on tongue axle and be articulated with pressure tongue; The bottom arm of force of this pressure tongue is flush end, and a pressure hyoid tooth is upwards stretched out in edge in the one end along the bottom arm of force.
Described upper pressure tongue axle is made up of round steel.
The end of described pressure tongue flush end is provided with the lifting hole(eyelet) for steel wire penetrating, and pressure tongue is provided with hook.
Described pressure hyoid tooth is obtuse angle with the bottom arm of force of pressure tongue, and the arm of force lateral, bottom of pressure tongue is arcwall face, and arcwall face is provided with several pressure hyoid tooth.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it can not only utilize steel pipe deadweight to make clamp press tongue freely to compress steel pipe, and vertical steel pipe can be sling; After steel pipe is in place, pull at slip rope time, pressure tongue can be unclamped by the deadweight of clamp, and transferring and after droping to the height of convenient operation, hung over by steel rope in hook, can clamp be promoted, achieve again the releasing to loop wheel machine with hoisting crane; When solving lifting steel pipes, need the problem of welding, dismantling suspension centre; Greatly realize saving material, improve lifting efficiency, avoid causing negatively influencing to steel pipe.

Detailed description of the invention
As Fig. 1, shown in Fig. 2, the present invention is provided with: several piece arc plate 1 (the present embodiment is four pieces), by the pressure tongue axle 2 be arranged between several piece arc plate, several piece arc plate 1 is connected into a closed circular ring structure, wherein, pressing on tongue axle 2 adopts axis hole connection mode to be articulated with pressure tongue 3; The bottom arm of force of this pressure tongue 3 is flush end, and a pressure hyoid tooth 4 is upwards stretched out in edge in the one end along the bottom arm of force.
Above-mentioned pressure tongue axle 2 is made up of round steel, and pressure tongue axle 2 adopts welding manner to be arranged between several piece arc plate 1.Pressure tongue axle 2, as pressure tongue 3 working shaft, to realize the free rotating function of pressing tongue 3, completes and is hung compression and the release of steel pipe 7.
The flush end end of above-mentioned pressure tongue 3 is provided with the lifting hole(eyelet) 5 passed for steel rope 8, and pressure tongue 3 adopts welding manner to be provided with hook 6.
Above-mentioned pressure hyoid tooth 4 is obtuse angle with the bottom arm of force of pressure tongue 3, and the arm of force lateral, bottom of pressure tongue 3 is arcwall face, and arcwall face is provided with several pressure hyoid tooth.
As Fig. 3, shown in Fig. 4, during actual use, the present invention is enclosed within by the outside of lifting steel pipe 7, utilize and produced contraction moment by the arm of force of the deadweight of lifting steel pipe 7 and pressure tongue 3, make pressure tongue 3 of the present invention freely compress by lifting steel pipe 7, pressure tongue 3 is when steel rope 8 tightens up, naturally can be engaged by lifting steel pipe 7, thus vertically will be sling by lifting steel pipe 7; Then, pull at slip rope time, pressure tongue 3 can be untied and discharge by lifting steel pipe 7, and transferring with hoisting crane, and when droping to suitable height, steel rope 8 is hung in hook 6, pressure tongue 3 can be made restricted, and can not be engaged by lifting steel pipe 7, then, lifting cranes can remove the present invention.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
