Abstract
The utility model relates to a mechanical self-tripping clamping and lifting device which comprises a lifting block, wherein four connecting plates are connected to the lifting block through shafts, the four connecting plates are uniformly distributed, clamping hooks are respectively connected to the lower ends of the connecting plates, connecting rods respectively penetrate through the part between every two clamping hooks which are oppositely arranged, outer frames are respectively connected to the top ends of the connecting plates, and lifting lugs are respectively arranged on the outer frames. By adopting a basic lever principle, self clamping is realized, and the mechanical self-tripping clamping and lifting device has the advantage of simple and compact structure; especially, after a high tower drum is assembled, the mechanical self-tripping clamping and lifting device has a self-tripping function, and the link that personnel remove a lifting tool is omitted; and compared with the existing traditional lifting mode such as an eyebolt and the like, the mechanical self-tripping clamping and lifting device has high safety and reliability.
Description
Technical field
The utility model relates to the tight lifting appliance of mechanical autospasy clip, the group that is applicable to land, offshore wind farm construction tower cylinder to and occasion is installed.
Background technology
At present, conventional tower cylinder vertical lifting suspender adopts lifting eye bolt more, is connected with steel rope lifting by bolt with tower cylinder top flange hole, and lifting eye bolt tighten, demolishing process all needs operating personnel's ascend operation, be unfavorable for personal security, and production time are long.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, safe, tight lifting appliance of mechanical autospasy clip that reliability is high is provided.
The purpose of this utility model is achieved through the following technical solutions: the tight lifting appliance of a kind of mechanical autospasy clip, comprise lifting piece, lifting piece is connected with four connecting panels by axle, four connecting panels are uniformly distributed, the lower end of each connecting panel is all connected with clamping grab, between every two clamping grabs that are oppositely arranged, be penetrated with pipe link, the top of connecting panel is all connected with outside frame, on each outside frame, is equipped with hanger.
The utility model compared with prior art has the following advantages: the utility model adopts basic lever principle to realize from clamping, simple in structure, compact, especially in altitude tower cylinder group to after completing, possesses automatic tripping function, remove the link that personnel remove suspender up and down from, compare the lifting methods such as at present traditional lifting eye bolt, there is very high safety and reliability.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-lifting piece, 2-axle, 3-connecting panel, 4-clamp grab, 5-pipe link, 6-outside frame, 7-hanger.
detailed description of the invention:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of embodiment of the tight lifting appliance of the utility model machinery autospasy clip, comprise lifting piece 1, lifting piece 1 is connected with four connecting panels 3 by axle 2, four connecting panels 3 are uniformly distributed, the lower end of each connecting panel 3 is all connected with and clamps grab 4, between every two clamping grabs 4 that are oppositely arranged, be penetrated with pipe link 5, the top of connecting panel 5 is all connected with outside frame 6, on each outside frame 6, is equipped with hanger 7.
Lifting blower fan tower barrel state: after the steel rope of lifting piece 1 and hoisting crane is connected, slow decreasing is also slowly inserted in the flange of tower cylinder to the flange on blower fan tower barrel top, slowly play lifting piece 1, utilizing lever principle to make to clamp grab 4 outwards shrinks, prop up tower cylinder inside flange bottom stressed, thereby making to clamp grab 4 turns up after stressed and clamps the flange port of blower fan tower barrel, deadweight by blower fan tower barrel when lifting realizes the clamping to hoisting object, so just complete clamping process, continue lift hanger top steel rope, whole tower cylinder is also lifted, turn round through loop wheel machine, tower cylinder is placed into designated area by luffing, open, close stressed hook and complete whole lifting action.Rapid unhooking blower fan tower barrel state: blower fan tower barrel is hung and lifts piece 1 after assigned address and slowly transfer, at this moment make the lower plane of outside frame 6 and the flange face of blower fan tower barrel contact, thereby make to lift piece 1 and throw off hoisting crane, when lifting piece 1 does not have upper lifting force, thereby that leans on this covering device inwardly receives from gravity the grab that clamps grab 4, at this moment hanger 7 draws on hanging on the steel rope of hoisting crane, realizes the function of rapid unhooking.
The utility model is for being applied to the assembled lifting appliance of wind-powered electricity generation basis tower cylinder, and its radical function is the situation of vertically placing at tower cylinder, does not need people for the extension suspension centre of ascending a height, and can automatically locate to realize to clamp.Tower cylinder is assembled possesses automatic tripping function after completing, and equipment package can be realized whole actions without power supports such as electric, hydraulic pressure, pure mechanical lever mechanism, and dependable with function is all well improved.
