Cause great industrial accident.Therefore it requires operator to be alert at all times during handling negative endless tube piece, and must make
Lifting less important work is carried out with specific purpose tool.
Summary of the invention
In view of this, the utility model be directed to it is a kind of for lifting the component of shield duct piece, it is negative to solve shield machine
In endless tube piece demolishing process, the big problem of shield duct piece hoisting difficulty.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
It is a kind of for lifting the component of shield duct piece, including connecting column, connecting plate and fixture nut；Connecting column is an arc
The steel column of shape, the starting point of connecting column is fixed on the lower end of connecting plate, the position of proximal end is leaned on to be equipped with screw thread on connecting column, fixed
Nut is applied on connecting column, positioned at the end of thread of connecting column.
It further, further include gasket in the component for lifting shield duct piece, gasket is applied on connecting column, position
In the end of thread of connecting column, and it is mounted on the inside of fixture nut.
Further, connecting plate is the metal plate of U-shaped.
Further, connecting column is welded on the lower end of connecting plate.
Further, connecting plate is equipped with hole for hoist.
Compared with the existing technology, the utility model has the advantage that
(1) it is equipped with hole for hoist in the component described in the utility model for lifting shield duct piece, in lifting shield duct piece
When, it is connected firmly, makes in negative endless tube piece demolishing process with section of jurisdiction, hoist cable has stable point to hang, and section of jurisdiction unstability is avoided to fall wound
People improves the safety coefficient of production scene.
(2) because the shape of shield duct piece is more special, bolt installation is inconvenient when being lifted using plain bolt, the utility model
In the component for lifting shield duct piece, connecting column is arc, and such structure design will can more easily connect
It connects column to be mounted in the bolt hole of section of jurisdiction, and connecting column is more uniformly stressed, be not easily broken, construction safety performance can be reinforced.
(3) the component manufacture craft is simple, material easy processing, and required quantity is few, and overall cost is low, easy to operate, real
It is strong with property, it can promote the use of a large area.
