A large ball valve spool replacement hoisting transmission device

Abstract

The invention relates to a large-scale ball valve spool replacement hoisting transmission device, which includes a support frame, a positioning device and a lifting device. The support frame has a T-shaped structure, the middle part of the support frame is a hollow structure, and a positioning device is symmetrically installed inside the support frame. , a hoisting device is arranged above the positioning device, and the hoisting device is installed in the middle of the upper end of the support frame. The present invention can solve the problem that the existing equipment cannot accurately locate the ball valve when the ball valve core is disassembled, and the movement of the valve body after disassembly is inconvenient, which is not conducive to the replacement and processing of the subsequent valve core. At the same time, the existing equipment When replacing the spool of the ball valve, the spool cannot be positioned and clamped accurately, the operation is complicated, and the clamping effect is poor, which leads to the phenomenon that the spool after lifting is easy to fall off, and it is easy to affect the safety of workers and other problems. .

Description

technical field [0001] The invention relates to the field of ball valve spool replacement processing, in particular to a large ball valve spool replacement hoisting transmission device. Background technique [0002] Ball valve is a common valve with the advantages of compact structure, light weight, small fluid resistance loss and convenient maintenance and operation. Ball valves are mainly used in pipelines to cut, distribute and change the flow direction of media. It only needs to use The operation of rotating 90 degrees can be closed tightly. Ball valves are most suitable for on-off and shut-off valves. The main features of ball valves are their compact structure, reliable sealing, and simple structure. They are widely used in medium conveying pipelines in various fields. [0003] At present, the existing large-scale ball valve spools usually have the following defects during the replacement process: 1. The existing equipment cannot accurately position the ball valve whe...
