Abstract
The utility model relates to a connecting pin shaft for lifting a large constructional element. The connecting pin shaft comprises a pin shaft main body, a left limiting plate and a right limiting plate are installed at two ends of the pin shaft main body, the diameter of the left limiting plate is greater than the that of the right limiting plate, the left limiting plate is fixed on the pin shaft main body through a bolt, and the right limiting plate is fixed on the pin shaft main body through a bolt. The connecting pin shaft for lifting the large constructional element is simple in structure, scientific and reasonable in design, simple in manufacture, low in cost, capable of achieving stable lifting of the large constructional element, safe and reliable.
Description
Technical field
The utility model belongs to the bearing pin field, and especially a kind of lifting large-scale component is with connecting bearing pin.
Background technique
Large-scale component is installed needs higher technological means, 660MN extruding/drop press is the heavy drop press of the prestressing force of present China maximum, 660MN press volume: high 25.7 meters, wide 9.5 meters, thick 8.3 meters, 4300 tons of the hoisting weights after the frame assembling of this 660MN extruding/drop press.Large volume, heavy weight frame integral installation still belong to the first at home and abroad like this, the construction process that need to use horizontal sliding in whole frame assembling process, promotes upset, need to realize hinged between each suspender in these techniques, common small-sized bearing pin can't be realized.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of lifting large-scale component with connecting bearing pin, and the stable lifting that this pin shaft structure is simple, design science reasonable, it is simple to make, cost is lower, can realize large-scale component is safe and reliable.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of lifting large-scale component comprises a bearing pin main body with connecting bearing pin, and left limit plate and right limit plate are installed respectively in its two ends in the bearing pin main body.
And the diameter of described left limit plate is greater than the diameter of right limit plate.
And described left limit plate is bolted on the bearing pin main body, and the right limit plate is bolted on the bearing pin main body.
Advantage of the present utility model and beneficial effect are:
This lifting large-scale component is with connecting bearing pin, comprise a bearing pin main body, left limit plate and right limit plate are installed respectively in its two ends in the bearing pin main body, the diameter of left limit plate is greater than the diameter of right limit plate, the left limit plate is bolted on the bearing pin main body, the right limit plate is bolted on the bearing pin main body, and the utility model is simple in structure, design science is reasonable, making is simple, cost is lower, can realize the stable lifting of large-scale component, and is safe and reliable.
