Many accidents for playing employee's finger and being weighed wounded by valve deck occur, have seriously affected the work health of employee, and a large amount of to company's band
Lost work.
Utility model content
For the above technical problems, the purpose of this utility model is：Propose a kind of lifting of internal taper hole flange
Structure.
What the technical solution of the utility model was realized in：A kind of hoisting structure of internal taper hole flange, including method
Blue and lifting device is provided with multiple bolt connecting holes on flange, through-hole is provided in the middle part of flange；The lower part of the through-hole is
Taper hole；The lifting device includes sunpender, sleeve and multigroup arm component；The sleeve is set on sunpender, the upper end of sunpender
It is provided with up knob, the upper end of sleeve is provided with lower handle；The arm component includes fixed link, depending post and connecting rod, Gu
Fixed pole is fixedly connected with sleeve, and the both ends of depending post are hinged with fixed link and connecting rod respectively, the both ends of connecting rod respectively with
It closes bar and sunpender is hinged, the outside portion of depending post and the internal taper hole of flange coordinate.
Preferably, it is provided with bumper on the lateral wall of the depending post.
Preferably, the upper end and middle part of the fixed link are welded on sleeve, and the lower end of connecting rod and sunpender is hinged.
Preferably, the arm component is provided with 3 or 4 groups, and multigroup arm component is uniformly arranged around the axis of sunpender.
Preferably, multiple finger slots are provided on the downside of the lower handle.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
The hoisting structure of the internal taper hole flange of the utility model, is exclusively used in the flange with internal taper hole, by lifting device with
The internal taper hole of flange coordinates, and lifting carrying is carried out to flange, and lifting device is simple in structure, easy to operate, improves handling efficiency,
And the case where finger is weighed wounded is avoided, has ensured workers ' health, reduces lost work.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic diagram of the hoisting structure of internal taper hole flange of the utility model.
Specific implementation mode
Illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Fig. 1, the hoisting structure of a kind of internal taper hole flange described in the utility model, including flange 1 and lifting
Tool is provided with multiple bolt connecting holes 2 on flange 1, and the middle part of flange 1 is provided with through-hole；The lower part of the through-hole is taper hole；
The lifting device includes sunpender 3, sleeve 4 and multigroup arm component；The sleeve 4 is set on sunpender 3, the upper end of sunpender 3
It is provided with up knob 5, the upper end of sleeve 4 is provided with lower handle 6；The arm component includes fixed link 7, depending post 8 and connection
Bar 9, fixed link 7 are fixedly connected with sleeve 4, and the both ends of depending post 8 are hinged with fixed link 7 and connecting rod 9 respectively, connecting rod 9
Both ends are hinged with depending post 8 and sunpender 3 respectively.
The operation principle of lifting device is, by the relative motion of sunpender 3 and sleeve 4, to make fixed link 7, depending post 8 and connect
The link mechanism variation that extension bar 9 forms；For example, with sleeve 4 for fixed benchmark, made under sunpender 3 by pressing up knob 5
When drop, depending post 8 can be driven to expand outwardly by connecting rod 9, make the inclined-plane of the outside portion of depending post 8 and the internal taper hole of flange 1
At this moment cooperation keeps sunpender 3 relatively motionless with sleeve 4, flange 1 can be sling by lifting up knob 5 and lower handle 6；It is moved to
Behind position, it is lifted up up knob 5, so that depending post 8 is inwardly withdrawn, you can to take out lifting device from flange 1.
Further, it is provided with bumper 10 on the lateral wall of the depending post 8, it can be to avoid damage flange 1 when lifting
Inner hole wall, bumper 10 use anti-abrasive material, be arranged on depending post 8 by modes such as gluings.
Further, the upper end and middle part of the fixed link 7 are welded on sleeve 4, and connecting rod 9 and the lower end of sunpender 3 are cut with scissors
It connects, to ensure the stability of lifting device.
Further, the arm component is provided with 3 or 4 groups, and multigroup arm component is uniformly arranged around the axis of sunpender 3,
The hoisting structure of 3 pawls or 4 pawls is formed, ensures the stability of lifting work.
Further, the downside of the lower handle 6 is provided with multiple finger slots, refers to slot and finger and coordinates, easy to operation, can be with
Hand or hands are selected to operate lifting device according to the weight of flange, it is very convenient.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
