Abstract
The utility model discloses a multi-bolt hoisting tool of a cylinder, which comprises a hoisting cross rod, hoisting rings connected with both ends of the hoisting cross rod, and a steel wire rope connected with the two hoisting rings; the hoisting cross rod is provided with a section of longitudinal elongated hole and a plurality of horizontal pin holes, the screws of a plurality of connecting bolts penetrate through the elongated hole and are positioned below the hoisting cross rod, and the heads of the connecting bolts are arranged on the hoisting cross rod; and limiting pins inserted into the pin holes are arranged on two sides of each screw rod. The utility model discloses not only can once lift by crane many bolts, improve work efficiency, and the security is good.
Description
Technical Field
The utility model relates to a many bolts hoist and mount frock especially is used for many bolts hoist and mount frock of steam turbine cylinder.
Background
The joint surfaces of the steam turbine cylinders are connected by bolts, and as the capacity of the steam turbine increases, the number of fastening bolts used by the cylinders also increases. The diameter of the cylinder bolt of the large-scale unit reaches 120mm, the length exceeds 1000mm, the weight exceeds 200Kg, and the number exceeds 20. At present, because no special hoisting tool exists, only one bolt can be hoisted at a time when the cylinder bolt is hoisted at each time, time and labor are wasted, and the efficiency is low.
Disclosure of Invention
The utility model aims at the aforesaid that prior art exists is not enough, provides a many bolts hoist and mount frock of cylinder, and it not only can once lift by crane many bolts, improve work efficiency, and the security is good.
In order to achieve the purpose, the multi-bolt hoisting tool for the cylinder comprises a hoisting cross rod, hoisting rings connected with two ends of the hoisting cross rod, and a steel wire rope connected with the two hoisting rings; the hoisting cross rod is provided with a section of longitudinal elongated hole and a plurality of horizontal pin holes, the screws of a plurality of connecting bolts penetrate through the elongated hole and are positioned below the hoisting cross rod, and the heads of the connecting bolts are arranged on the hoisting cross rod; both sides of each screw rod are provided with limit pins inserted in the pin holes;
when the device is used, the screw rod of each connecting bolt is screwed into the lifting hole of the fastening bolt to be lifted, and the fastening bolts can be lifted through the steel wire rope; the limiting pins on the two sides can prevent the connecting bolts from sliding, so that a plurality of bolts can be lifted at one time, the working efficiency is improved, and the safety is good;
as a further improvement of the utility model, the hoisting ring is connected with the two ends of the hoisting cross rod through threads; the assembly of the tool is convenient;
to sum up, the utility model discloses not only can once lift by crane many bolts, improve work efficiency, and the security is good.
