Abstract
The utility model discloses a lifting tool of a flying shear blade, which is disposed on the suspension hook of the crane, to lift the flying shear blade, the lifting tool comprises a support and a clamping component for hooking the flying shear blade, above the support is provided a hanger connected to the suspension hook, the clamping component is disposed at the two ends of the support, and is connected to the support. The lifting tool adopted in the utility model not only improves the installation and replacing precision and the maintenance efficiency of the flying shear blade, but also ensures the purpose of the in-situ safe lifting. The lifting tool is also characterized by simple structure and in-situ easy operation.
Description
Technical field
The utility model relates to the lifting accessory appliances of flying shear blade in the metallurgy industry, more particularly relates to a kind of lifting device of flying shear blade.
Background technology
In metallurgical rolling process, all to use flying shear on the manufacturing line, flying shear is the Fabricating machinery of a kind of energy fast shut-off iron plate, steel pipe, paper roll, is the shearing machine with fixed length of hot rolling, high-speed rod and screw-thread steel.For example, the drum-type crop flying shear is positioned at hot-rolling line finishing mill inlet, is used to excise intermediate blank fitfull head and afterbody.So need to be provided with crop flying shear before finishing mill, to guarantee the nip quality of slab in the finish rolling process, the cutting edge of flying shear needs often to change.But because cutting edge has 300 kilogram weights, there is not at present special-purpose lifting device yet, therefore in the process of each replacing cutting edge, can only adopt the direct mode that lifts of steel rope as shown in Figure 1,1 is flying shear blade among the figure, 2 is steel rope, 3 is travelling crane hook, because flying shear blade 1 is directly regulated by travelling crane hook 3 by steel rope 2, accuracy rate when causing flying shear blade 1 is installed is not high, replacing speed is very slow, and heavy weight flying shear blade 1 is very easy to wearing and tearing steel rope 2, makes steel rope 2 break and influences installation, and serious words also can produce the personal safety of operating personal and threaten.
The utility model content
Accuracy rate is not high when exist changing flying shear blade in the prior art, and the problem that replacing speed is very slow, the purpose of this utility model provide a kind of lifting device of flying shear blade, can improve the accuracy rate when changing flying shear blade.
To achieve these goals, the utility model adopts following technical scheme:
A kind of lifting device of flying shear blade is located on the suspension hook of driving, in order to the lifting flying shear blade, the hold assembly that comprises support and hook flying shear blade, the top of support is provided with the hanger that links to each other with suspension hook, and hold assembly is located at the two ends of support, and is connected with support.
Described hold assembly comprises hook and spring, and hook passes the waist shaped hole below the support, is connected and fixed above one end and the support, and the other end is connected with flying shear blade; Spring is located at the below of support, and an end of spring is connected with hook, and the other end was connected with the following of support.
Described support is the shape that two channel-section steel butt welding form.
The material of described hook is a reinforcing bar.
Compared with prior art, adopt the lifting device of a kind of flying shear blade of the utility model, be located on the suspension hook of driving, in order to the lifting flying shear blade, the hold assembly that comprises support and hook flying shear blade, the top of support is provided with the hanger that links to each other with suspension hook, and hold assembly is located at the two ends of support, and is connected with support.Owing to adopted lifting device, not only improve the precision that flying shear blade is installed, changed, improve the overhaul efficiency of flying shear blade, and guarantee the purpose of site safety lifting.Characteristics such as this lifting device also has simple in structure, and execute-in-place is easy.
Description of drawings
Fig. 1 is a structural representation of changing flying shear blade in the prior art;
Fig. 2 is the structural representation of the lifting device of the utility model flying shear blade;
Fig. 3 is the structural representation of Fig. 2 medium-height trestle;
Fig. 4 is the structural representation of linking up with among Fig. 2;
Fig. 5 is the structural representation of Fig. 2 medi-spring.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also the lifting device 10 of Fig. 2 to a kind of flying shear blade shown in Figure 5, be located between the suspension hook and flying shear blade 1 of driving, the hold assembly 12 that comprises support 11 and hook flying shear blade 1, the top of support 11 is provided with hanger 13, be used for passing steel rope, the lifting of convenient driving.Hold assembly 12 is located at the two ends of support 11, and is connected with support 11.Hold assembly 12 comprises hook 121 and spring 122, and hook 121 passes the waist shaped hole below the support 11, and waist shaped hole can make hook 121 slide inside, hooks flying shear blade 1.Link up with 121 1 ends and captive joint with the circular hole that support 11 is opened above, the other end is connected with flying shear blade 1; Spring 122 is located at the below of support 11, and an end of spring 122 is connected with hook 121, and the other end was connected with the following of support 11.Support 11 adopts the channel-section steel butt welding to form, and can guarantee that like this support 11 has enough bending strengths.The material of hook 121 is a reinforcing bar.
During installation, hexagonal nut 14 is enclosed within on the hook 121, and firm welding plays the effect of location, spring 122 1 ends are welded on the hexagonal nut 14, and another is welded on the support 11, are used for back-moving spring 122.After hook 121 being passed the waist shaped hole and top circular hole of support 11, fixing with hexagonal nut 15.In the time will using this lifting device 10, only need draw back the hook 121 on both sides, fastening is in the tapped bore at flying shear blade 1 two ends, and like this, hook 121 just can not come off automatically, and safety performance is high.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
