Description
Technical field
The utility model relates to a kind of hoisting sling, and in particular, it relates to a kind of hoisting chain of convenient location.
Background technique
Hoisting chain rigging is the rigging be formed by connecting with metal chain link, divide by its form and mainly contain welding procedure and assembly two kinds, have single limb and many limbs etc. by its structure point, the chain generally consisted of chain shackle and some chain links top suspension ring is connected, and client arbitrarily can combine and organize chain more.
Hoisting chain needs the length according to the lifting height different adjustment chain playing weight, traditional chain is generally the strip metal chain be connected to form between two between the chain link of metal or annulation, and chain link is after to be vertical bar metal bending by processing, the cycle object that vertical bar metal two ends welded seal becomes, mutually be socketed between chain link, form spendable chain.But by the chain that welding chain link is combined into, length is fixing, if in using process, encountering special circumstances needs interim prolongation or shortening chains, and the chain link of welding in advance is just difficult to be separated, and disassembling, assembling and replacing is very inconvenient, will certainly affect the efficiency of field operation; In addition on the one hand, when the power pullled is excessive during operation, likely make chain link weld be separated, make to be separated between chain link, cause chain damaged, cannot on-call maintenance, cause chain to waste, affect the integrity of chain simultaneously, carrying out smoothly of obstruction work.
Moreover the suspension centre of hoisting machinery lift hook requires with lift heavy center of gravity on same vertical line, makes lift heavy be in stability, produce when preventing from promoting and slide or topple, and two traditional chain links connect, arc inner wall easily swings, the same stability affecting chain, is unfavorable for operation.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is that open one can adjusting chain length at any time, and can rapid adjustment lift heavy center of gravity on a vertical line, facilitate lifting operation.
For achieving the above object, the utility model provides following technological scheme: a kind of hoisting chain of convenient location, comprise suspension ring, hook, described suspension ring unload to detain by chain and connect some chain links, last chain link coupling hook, described chain link is connected and composed by the half chain link symmetry that two take the shape of the letter U, the both ends of the surface of the U-shaped open at one end of one of them half chain link are provided with the fixture block of swallow-tail form, the U-shaped open at one end of another half chain link corresponds to fixture block place and is provided with the draw-in groove matched with fixture block, the joint flip sleeve that described chain link corresponds to fixture block and draw-in groove is provided with the elastic reset part avoiding fixture block and exact separation.
By adopting technique scheme, when needing to be connected to form spendable chain between chain link, one end of the U-shaped opening of half chain link is arranged in corresponding, and fixture block is placed in draw-in groove, then by the sheathed fixation of elastic reset part, make it possible to fixing fixture block in draw-in groove, avoid the situation that fixture block comes off in draw-in groove, improve the mechanical stability between half chain link, and the using effect of chain can be improved, avoid the fracture of chain, coordinating and sheathed fixing by elastic reset part additionally by fixture block and draw-in groove, workman can be improved the efficiency coordinating chain is installed.In this hoisting chain operation, can the length of adjusting chain at any time, to adapt to different lift position, and in adjustment process, chain link easy accessibility, reusable.
Further, described elastic reset part includes flip sleeve and is located at retaining ring on chain link, and be set in that on chain link and one end is fixed on retaining ring, the other end is fixed on elastic component on chain link, described Fixing shrink ring is located on the position of fixture block and draw-in groove joint.
Further, described retaining ring is provided with the block protruded towards chain link near the side of chain link, and described chain link is provided with the back-up ring protruded towards retaining ring, and back-up ring is away from the joint of fixture block and draw-in groove, and described elastic component is between block and back-up ring.
Further, described chain link is provided with groove for the middle part hanging the lower end connecting another chain link, and the width of described groove is not less than the diameter of chain link.A upper chain link arranges groove at itself and next chain link joint, when upper and lower chain link connects, lower chain link can slide to groove automatically due to Action of Gravity Field, and next chain link blocks and prevents it from significantly swinging by groove, be beneficial to rapid adjustment lift heavy center of gravity, increase work efficiency.
Further, described groove is made up of both sides joint and bottom, and described joint is connected with the both sides inwall of half chain link of U-shaped, and joint rounding, the joint rounding of described bottom and joint.Rounding plays a leading role.
Further, described suspension ring or chain shackle or chain link or the hook surperficial coating plastic layer of one or more wherein, be coated with protective layer outside described plastic layer.
The utility model takes above-mentioned corrective measure to carry out, its beneficial effect is remarkable: coordinate by fixture block and draw-in groove the installation efficiency making it possible to improve workman, and by the cooperation between half chain link, make it possible to the length lengthening or shorten chain, hoisting chain can be applicable to different lift position at any time, simultaneously the positioning action of fit, and two chain link clampings are compacter and more stablely not easily move, can rapid adjustment lift heavy center of gravity, increase work efficiency.
