(2) background technology
The main lifting structure that derrick is produced as the mine, the sign in industrial place occupy critical role in whole mine engineering.As everyone knows, big shield formula derrick is because power transmission is succinctly clear and definite, rational in infrastructure, and head configuration is simple, and steel using amount is economized, and when only using permanent derrick as production, should adopt this pattern.But height is greatly like the above big shield formula structure derrick of 50m; Usually install back displacement just very big, use in horizontal movement very big; Be difficult to satisfy code requirement, and cause easily influencing Hoisting System and compelled the reinforcing, domestic had such case; Though or satisfy code requirement but steel using amount significantly increases, the scope of application of big shield formula derrick is restricted.
(3) summary of the invention
The utility model is in order to remedy the defective of prior art, and a kind of big shield formula steel headframe that displacement is less, steel using amount is saved during height more than 50m is provided.
The utility model is realized through following technical scheme:
A kind of big shield formula steel headframe; Comprise stand and oblique frame, tiltedly the top of frame is provided with sheave wheel platform, following sheave wheel platform and maintenance lifting platform, and it is characterized in that: stand comprises stand front pillar and stand rear pillar; Stand and the middle parallel chord truss formula diagonal brace that is equipped with of oblique frame; Tiltedly frame is installed with the stand upper end through oblique frame bracket mutually, and the stand lower end is provided with the stand suspension column, and tiltedly the frame lower end is provided with oblique trestle pin.
This big shield formula steel headframe; Parallel chord truss formula diagonal brace is installed in the center of stand rear pillar; Parallel chord truss formula diagonal brace is with tiltedly frame is perpendicular, and parallel chord truss formula diagonal brace all adopts high-strength bolt to be connected with stand rear pillar, oblique frame, and parallel chord truss formula diagonal brace is made up of high-strength bolt hinged H shaped steel and angle steel.Tiltedly the active position of frame bracket in stand is by the oblique frame direction of mind-set in stand translation certain distance, the last node translation thereupon of stand top web member.Tiltedly the axis of frame is the line through upper and lower head sheave center line, and tiltedly frame two posts diverge to width and are not less than 1/3 of derrick height, and will satisfy stability calculation requirement outside the plane.The planar dimension of stand is not less than 1/10 of derrick height.Be provided with a section steel beam between the two oblique frame brackets, section steel beam is positioned at the top flange of bracket beam, welds with the bracket beam.The stand suspension column adopts and rigidly connects suspension column, and tiltedly the trestle pin adopts fixed-hinged support.Stand front pillar and stand rear pillar adopt H shaped steel cross section or H shaped steel to add the T-steel compound section, and tiltedly trestle adopts the weld tee section.
The beneficial effect of the utility model is: this big shield formula steel headframe, reasonable in design, steel using amount is saved, and more than 50m during height displacement less, satisfy standard and technological requirement easily, use more extensive.
