On the basis of the above scheme, the utility model discloses following improvement has still been made:
the tool further comprises a lifting lug II, and the lifting lug II is horizontally arranged and fixedly connected in front of the blind plate; the front ends of the two horizontal rails on the side sides are connected through a cross beam, a guide vertical plate perpendicular to the lifting lug II is arranged on the cross beam at the front end, and a guide hole arranged along the moving direction of the tool is formed in the guide vertical plate.
The utility model has the advantages and positive effects that: through adopting small rail car and spiral elevation structure, utilize small rail car to carry out horizontal migration, utilize spiral elevation structure to support replacement and position lift, through the adjustment lead screw, make the blind plate take one's place, can avoid the hoist and mount operation to adopt chain block or the light convenience of manual fit rope made of hemp operation, work efficiency is high, safe and reliable. Is suitable for operation in narrow space and has good use effect.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention.
In the figure: 1. a straight roller; 2-1, a horizontal track positioned at the side; 2-2, a horizontal rail in the middle; 3. a column; 4. a pin shaft; 5. a wheel carrier; 6. a nut; 7. a screw rod; 8. a lifting lug I; 9. a front end cross member; 10. a guide vertical plate; 11. a blind plate; 12. a pipeline; 13. and a lifting lug II.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1 and 2, a tool for plugging a vertical large-diameter pipeline blind plate comprises three straight rollers 1 arranged on the periphery of the blind plate 11, wherein two straight rollers 1 are respectively arranged on two sides of the blind plate 11, the other straight roller 1 is arranged behind the blind plate, the three straight rollers 1 are respectively assembled on three mutually parallel and mutually connected horizontal rails, the horizontal rails are supported on a steel structure platform around a pipeline 12 by adopting upright posts 3, two horizontal rails 2-1 on the sides respectively cross two sides of the pipeline 12, and the front end of the horizontal rail 2-2 in the middle is stopped at the rear side of the pipeline 12.
The straight roller 1 is connected with a wheel frame 5 through a pin shaft 4, one side of the wheel frame 5 is connected with the periphery of a blind plate 11, a horizontally arranged screw 6 is fixedly connected onto the wheel frame 5, a vertically arranged screw rod 7 is connected onto the screw 6, and when the blind plate is placed in place, the lower end of the screw rod 7 is pressed on a corresponding horizontal track.
