Description
Technical field
The present invention relates to a kind of suspension column structure, especially a kind of suspension column structure of large-span steel trestle.
Background technology
Often there is windrow place in industries such as electric power, papermaking, steels, stacker and steel construction stack are used on the ground in rickyard
The mode that bridge is combined carrys out automatic heap and takes bulk material.In order to ensure the usable floor area in windrow place, general steel trestle
Span design it is bigger, but the too conference of steel trestle span causes the stress between steel trestle and stacker more next
It is more complicated.With becoming larger for steel trestle span, the stress (horizontal thrust, vertical pressure) of stacker newel also gradually increases
Greatly.For ordinary circumstance, stacker newel bears vertical pressure, and there is no problem, but horizontal thrust is to stacker newel
Influence is especially huge, prolonged to influence to be easy to cause newel fracture.
Invention content
The object of the present invention is to provide a kind of suspension column structures of large-span steel trestle, can reduce stacker
The horizontal thrust that newel is born.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of column of large-span steel trestle
Leg structure, including steel trestle and column, column are arranged in the lower section of steel trestle, and are connect with steel trestle；It is vertical
The bottom position of column is provided with height adjustment device, and height adjustment device is fixedly connected with basic built-in fitting；Height adjusts dress
It sets including positioning device, upright post connecting plate and bolt adjusting part, positioning device is fixedly mounted on the basic built-in fitting, is stood
Column connecting plate is arranged in the top of positioning device, and bolt adjusting part is arranged between positioning device and upright post connecting plate, bolt
Adjusting part is connect with positioning device, and bolt adjusting part is also connect with upright post connecting plate.Height adjustment device is simple in structure, adopts
With the height adjustment device convenient for improve steel trestle to be located at the equipment such as trestle end stacker-reclaimer (such as stacker) by
Power, the structure type is simple, cost also increases too much, conducive to promoting the use of compared with common foot joint.Positioning device
For positioning vertical column, and it is fixedly connected with bolt adjusting part, is adjusted come the final height for realizing column by bolt adjusting part,
To realize the thrust for reducing steel trestle to the equipment such as end stacker-reclaimer (such as stacker).In a certain range,
As stem height is adjusted down, steel trestle is to acting on the equipment such as end stacker-reclaimer (specifically, such as stacker center
Column) on thrust be gradually reduced.Therefore, in a certain range, after so that stem height is reduced by adjusting height adjustment device, energy
Steel trestle is enough effectively reduced to being located at the horizontal thrust of the equipment such as trestle end stacker-reclaimer (such as stacker newel), reason
It is acted in the equipment such as end stacker-reclaimer (specifically, such as acting on stacker newel) by steel trestle above may be implemented
Thrust be zero.In a kind of suspension column structure of large-span steel trestle above-mentioned, the bolt adjusting part includes at least four
