Abstract
The utility model relates to a rope for vertically lifting a cylindrical transmission shaft; the rope comprises a hoop defined by two half hoops, and the connecting ends of the two half hoops are fastened and connected with each other by bolts; the two half hoops are respectively provided with at least one lifting lug; and the contact surfaces between the two half hoops and the cylindrical transmission shaft are respectively provided with a tooth-shaped structure used for improving the friction force. The rope is simple in structure and easy to manufacture; and the hoop is fastened and connected with the cylindrical transmission shaft, and the friction force between the hoop and the cylindrical transmission shaft can be improved by the tooth-shaped structures, so that the cylindrical transmission shaft are prevented from falling off when being lifted.
Description
Technical field
The utility model relates to the hoisting and hanging technical field, especially a kind of rigging for cylindrical transmission shaft vertical lifting.
Background technology
Modernization line production line of bar milling train layout all adopts vertical horizontally and vertically alternative tandem rolling formula, and the installation that is used for transmitting between gear case and the milling train versatile spindle of rolling torque thus also has level and vertical two kinds of installation forms.Yet domestic and international existing versatile spindle series of products all are not designed for vertically arranged hole for hoist or rigging on the axle body, have caused inconvenience and puzzlement for the vertical installation of vertical mill versatile spindle.At present, three in Changzhou under day iron and steel group company roll, five roll, six roll three subsidiary factories a bar and three wire rod production lines of online production, and what roll during it is thick that the part milling train all adopts is horizontally and vertically alternative formula tandem rolling layout.These three subsidiary factories are when installing the vertical mill versatile spindle, all imitate mutually, adopt the steel plate that welds two band holes for hoist before installing earlier at the versatile spindle cylindrical shaft on one's body symmetrically, treat that versatile spindle installs, for not influencing the normal operation of versatile spindle, the steel plate that will just weld falls with the acetylene gas cutting again.Before and after the weldering welding cut and will spend one hour artificial, employ the water power weldering, both waste material adds two scars for again new versatile spindle, in fact for exhausting the people and draining the treasury.To this, one line operating personnel repercussion is very big, also once to versatile spindle manufacturer the product additional requirement was proposed, namely at pillow block of versatile spindle axle body appropriate location processing, the way that hoisting ring is installed behind pillow block place drilling and tapping then solves lifting problem (seeing Fig. 1 Fig. 2, Fig. 3 Fig. 4), though this type of scheme is reliable, but because pillow block place diameter increases, increased the size of blank, the tooling cost of axle is increased, and also acquired a certain degree of difficulty at axle body brill hole for hoist.If pillow block directly upwards boring can influence axle be subjected to force intensity etc. owing to there is not suitable improvement project, have to maintain the statusquo.
The utility model content
The technical problems to be solved in the utility model is: overcoming the problem that cylindrical transmission axial workpiece is difficult to lift in the prior art, a kind of rigging for cylindrical transmission shaft vertical lifting is provided, is the hoisting Design of cylindrical transmission shaft specially.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of rigging for cylindrical transmission shaft vertical lifting, comprise the anchor ear that is surrounded by two and half hoops, the coupling end of two and half hoops connects by bolted, be equipped with at least one hanger on described two and half hoops, have the tooth-shape structure that improves friction force on the contact surface of two and half hoops and cylindrical transmission shaft.
Described tooth-shape structure is the serrated teeth that is distributed on half hoop.
The coupling end of described two and half hoops is equipped with a hanger that coincides together when two and half hoop combinations.
The beneficial effects of the utility model are, rigging structure for cylindrical transmission shaft vertical lifting of the present utility model is simple, be easy to make, be fastenedly connected by anchor ear and cylindrical transmission shaft, tooth-shape structure has increased the friction force of anchor ear and cylindrical transmission shaft, prevent that it from dropping in hoisting process, in the not safe and reliable lifting of the basis of injuring part realization as far as possible.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of first kind of structure of the prior art;
Fig. 2 is the birds-eye view of first kind of structure of the prior art.
Fig. 3 is that the master of second kind of structure of the prior art looks and partly cuts open figure;
Fig. 4 is the left view of second kind of structure of the prior art.
Fig. 5 is the front view of the rigging for cylindrical transmission shaft vertical lifting of the present utility model;
Fig. 6 is that the overlooking of rigging for cylindrical transmission shaft vertical lifting of the present utility model partly cutd open figure.
Among the figure: 1. half bind round 11. tooth-shape structures, 2. bolt, 3. hanger, 4. cylindrical transmission shaft.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the scheme drawing of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Figure 6 as Fig. 5, rigging for cylindrical transmission shaft vertical lifting of the present utility model, comprise by two and half hoops, 1 anchor ear that surrounds, the coupling end of two and half hoops 1 is fastenedly connected by bolt 2, two and half bind round the tooth-shape structure 11 that has the raising friction force on the contact surface that is equipped with 3, two half hoops 1 of at least one hanger and cylindrical transmission shaft 4 on 1.Tooth-shape structure 11 is for being distributed on the serrated teeth on half hoop.The coupling end of described two and half hoops 1 is equipped with a hanger 3 that coincides together when 1 combination of two and half hoops.
Utilize " serrated teeth " increase anchor ear of two and half hoops, 1 inside face and the friction force of axle body contact surface, by being applied to the predetermincd tension that anchor ear both sides coupling end tightens bolt 2, anchor ear is fixed on one's body the cylindrical transmission shaft 4 firmly, treat that cylindrical transmission shaft 4 installs, again anchor ear is disassembled, 4 need of the cylindrical transmission shaft of same like this specification, one cover anchor ear just can be finished the lifting of cylindrical transmission shaft, and make cylindrical transmission shaft 4 exempt from damage.
When using, reality needs according to the weight of cylindrical transmission shaft 4, the assumed (specified) loads such as material of rigging, in order to avoid in use because of the strength problem of rigging, cause safety misadventure.
