Abstract

The utility model discloses a universal hoisting tool which applies to solid of revolution structure components and parts. The hoisting tool comprises a boom and hanging talons. The number of the hanging talons is at least three. A first adapter ring is fixed on a tail end of the boom which is provided with a second adapter ring capable of sliding along the boom. One end of each hanging talon is hinged with the second adapter ring and the middle portion of each hanging talon hinges with the first adapter ring through a connecting rod. An end hook entirety of each hanging talon is of an arch structure. By means of the structure capable of automatically opening and telescoping, the hoisting tool can easily enable manufacturing work pieces to move and is convenient to use when hoisted work pieces are loaded and unloaded due to the fact that the structure of the hoisting tool is designed according to the lever principle. The end hooks of the hanging talons can be designed according to work piece structures and therefore hoisting is safer. When different work pieces are loaded and unloaded, the hoisting tool can facilitate replacement of the hanging talons.

Technical field

The utility model belongs to machine design and makes the field, especially belongs to lifting device and makes field, the particularly a kind of lifting device that can conveniently open and fix.

Background technology

Rotary structure parts commonly used, for example flywheel, belt wheel adopt the casting of high-quality cast steel usually.In the actual course of processing; Owing to need repeatedly processing; The operator needs its repeatedly upper and lower lathe, and at every turn in handling process, all needs manual the wearing of operator to hang handling after the steel rope balance workpiece center of gravity; Because of flywheel, belt wheel very easily damage steel rope for Casting Parts marginal existence casting overlap, burr; There is potential safety hazard in the steel rope that damages and stabs deficiency such as operating personal both hands again easily, more than some job safety that in actual production process, has influence on the operator with cause the handling steel rope to waste in a large number, be badly in need of a kind of simple and easy hoisting anchor clamps at present and solve above not enough.

Summary of the invention

The utility model discloses a kind of general lifting device that is applicable to the rotary structure parts according to the deficiency of prior art; The problem that the utility model will solve provides a kind of suspender that can conveniently open and fix; To the deficiency of suspender in the existing course of processing, improve the efficient of processing hoisting process.

The utility model is realized through following technical scheme.

Lifting device; Comprise suspension rod and hang pawl; It is characterized in that: hanging pawl has and is no less than 3, and the end of suspension rod has the first fixing coupling link, and second coupling link that can slide along suspension rod is arranged on the suspension rod; It is hinged that each hangs an end and second coupling link of pawl, and it is hinged through the pipe link and first coupling link that each hangs the middle part of pawl.

There is hook said end of hanging pawl.Hanging pawl is a bow-shaped structural.

The utility model lifting device is connected with weight-lifting equipment through suspension rod realizes handling; Suspension rod has two coupling links respectively; First coupling link is fixed on the suspension rod end through jam nut, and second coupling link slides on the pull bar of the upper end of first coupling link, and it is hinged through the pin and second coupling link to hang pawl one end; It is hinged with pipe link earlier to hang the pawl middle part; The pipe link other end and first coupling link are hinged, utilize ordinary bridge crane to produce the center of gravity that finds weight to upper pulling force and the downward principle of weight gravity automatically, and parts such as the pipe link through being attached thereto, the pin firmly tight weight of pawl are accomplished the lifting task fast.

Can also be provided with 4 according to handling purpose and the situation of being hung workpiece hangs pawl or more and hangs structures such as pawl.Hanging the pawl end hook can also be according to the structure design of handling workpiece.In actual use, in order further to increase safe lifting, can also safety lock structure be set at the hook that hangs the pawl end.

Comprehensively above-mentioned; The utility model helpfulness: but the utility model lifting device utilization self-opening and flexible structure are conveniently realized moving of processing work, and structure is utilized lever principle; When loading and unloading handling workpiece, all can conveniently use; Hanging the pawl end hook can make handling safer according to the Workpiece structure design, and when carrying out the different workpieces loading and unloading, the utility model structure can conveniently realize hanging the replacing of pawl.The bow-shaped structural that hangs pawl has further increased whole suspender ability, and more reasonable structure makes whole suspender safer and convenient, and the utility model suspender reduces labor intensity of operating staff and raises labour efficiency.

The specific embodiment

Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.

In conjunction with Fig. 2 to Fig. 3.

Lifting device; Comprise suspension rod 1 and hang pawl 3; Hanging pawl 3 has and is no less than 3, and the end of suspension rod 1 has the first fixing coupling link 8, and second coupling link 2 that can slide along suspension rod 1 is arranged on the suspension rod 1; It is hinged that each hangs an end and second coupling link 2 of pawl 3, and it is hinged through the pipe link 5 and first coupling link 8 that each hangs the middle part of pawl 3.

There is hook 3c the end of hanging pawl 3.Hanging pawl 3 is bow-shaped structurals.

Lifting device is connected with weight-lifting equipment through suspension rod 1 realizes handling; Suspension rod 1 has two coupling links respectively; First coupling link 8 is fixed on suspension rod 1 end through jam nut 4, and second coupling link 2 slides on the upper end pull bar 1 of first coupling link 8, and it is hinged through pin 6 and second coupling link 2 to hang pawl 3 one ends; It is hinged with pipe link 5 earlier to hang pawl 3 middle parts; Pipe link 5 other ends and first coupling link 8 are hinged, utilize ordinary bridge crane to produce the center of gravity that finds weight to upper pulling force and the downward principle of weight gravity automatically, the pipe link 5 through being attached thereto, pin parts such as 6 firmly the tight weight of pawl accomplish the lifting task fast.
