Abstract
The utility model discloses a kind of hoisting sling, including connector and the hook at the top of connector, it is characterised in that：The connector includes at least two layers of connecting tube, and the connection ring of taper is provided between the adjacent connecting tube, and the lightening hole of circle distribution is provided with the connection ring；Connection screw thread is provided with inside every layer of connecting tube, and is increased step by step from the nominal diameter of the superiors' every layer of connection screw thread into orlop.The utility model can be applied to the main shaft assembly of multiple sizes, not only increase lifting efficiency, and easily pipe is put, and saves space.
Description
【Technical field】
The technical field of hoisting machinery is the utility model is related to, more particularly to a kind of hoisting sling.
【Background technology】
With multiple compared with heavy parts in lathe production, one of them is main shaft assembly, main particularly in large-scale milling machine
Axle assembly is bulky, and installation requirement precision is again very high, it is necessary to lifted by wherein equipment, will be used in hoisting process
To lifting tool, however, for the main shaft assembly of different size, used tool size will be different, and multiple tools point
Do not place, not only occupy place, and also result in the man-hour loss brought in practicality by the process of replacing.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of hoisting sling, can be applied to
The main shaft assembly of multiple sizes, lifting efficiency is not only increased, and easily pipe is put, and saves space.
To achieve the above object, the utility model proposes a kind of hoisting sling, including connector and positioned at connector top
The hook in portion, it is characterised in that：The connector includes at least two layers of connecting tube, and cone is provided between the adjacent connecting tube
The connection ring of shape, the lightening hole of circle distribution is provided with the connection ring；Connection screw thread is provided with inside every layer of connecting tube,
And increase step by step from the nominal diameter of the superiors' every layer of connection screw thread into orlop.
Preferably, the connecting tube has three layers, respectively the first connecting tube, the second connecting tube and the 3rd from top to bottom
Connecting tube, the first connecting tube inside set the first connection screw thread, the second connection screw thread are set inside second connecting tube,
3rd connection screw thread is set inside the 3rd connecting tube.
Preferably, the hook at the top of the first connecting tube with being fixedly connected by welding.
The beneficial effects of the utility model：The utility model by the different connecting tube in multilayer aperture by being arranged to overall knot
Structure, and weld and link up with the superiors, so that a suspender can be adapted to the main shaft assembly of a variety of external diameters, improve main shaft assembly and hang
The efficiency of dress.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is external structure schematic diagram of the present utility model；
Fig. 2 is internal structure schematic diagram of the present utility model.
In figure：The connecting tubes of 1- first, the connecting tubes of 2- second, the connecting tubes of 3- the 3rd, 4- hooks, 5- lightening holes, 6- first connect
Connect screw thread, the connection screw threads of 7- second, the connection screw threads of 8- the 3rd.
【Embodiment】
Embodiment one,
Refering to Fig. 1 and Fig. 2, a kind of hoisting sling of the utility model, including connector and the hook at the top of connector
4, it is characterised in that：The connector includes at least two layers of connecting tube, and the company of taper is provided between the adjacent connecting tube
Ring is connect, the lightening hole 5 of circle distribution is provided with the connection ring；Connection screw thread is provided with inside every layer of connecting tube, and
Increase step by step from the nominal diameter of the superiors' every layer of connection screw thread into orlop.
Embodiment two,
The connecting tube has three layers, from top to bottom respectively the first connecting tube 1, the second connecting tube 2 and the 3rd connecting tube
3, the inside of the first connecting tube 1 sets the first connection screw thread 6, and the inside of the second connecting tube 2 sets the second connection screw thread 7,
The inside of 3rd connecting tube 3 sets the 3rd connection screw thread 8.
The hook 4 and the top of the first connecting tube 1 are fixedly connected by welding.
Utility model works process：
In the course of the work, the rotary shaft end of main shaft assembly can be provided with outer spiral shell to a kind of hoisting sling of the utility model
Line, the upright posture of connector (suspension hook is located at the top) of suspender are sleeved in the rotary shaft of main shaft, are revolved on connector with main shaft
The connection screw thread of the connection screw thread that spindle outer diameter matches inside connecting tube and main shaft rotary shaft matches, then can be to pass through
Purlin car plays hanging hook 4, is lifted main shaft assembly.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to the scope of protection of the utility model.
