Description
Technical field
The present invention relates to the improved methods and structure of a kind of gate and trash rack pull rod, belong to hydraulic and hydroelectric engineering metal structure
Technical field.
Background technique
For gate and trash rack pull rod, generally connected using the pin shaft arranged in the same direction between connected two section pull rods up and down
Connect, the direction of all pull rods deflection is all the same, this exist a wherein section pull rod shifted because environmental factors such as locks beam, gate or
Situations such as vibration of trash rack, deflects, and all pull rods deflect in the same direction as, this can make the amount of deflection of whole pull rod
It is larger, sometimes result in part pin shaft because stress is larger cut fixing bolt occur pin shaft be detached from pull rod accident cause damages,
Later period repair and maintenance difficulty is also larger, so, there is also deficiencies for the prior art, need to be further improved.
Summary of the invention
It is an object of the invention to provide the improvement side of a kind of gate and trash rack pull rod in order to overcome the deficiencies of the prior art
Method and structure.
Technical scheme is as follows:
Firstly, this method is by gate and to block dirt the invention proposes the improved method of a kind of gate and trash rack pull rod
Using the pin shaft connection for being mutually perpendicular to arrangement between the connected two section pull rods up and down of grid, make between connected two section pull rods up and down partially
The direction turned is vertical, wherein a section pull rod is because of situations such as such as being locked beam displacement, gate or the vibration of trash rack by environmental factors
It deflects, coupled pull rod will receive the power vertical with deflection direction, increase rubbing between its pin shaft and pull rod hole wall
Power to be wiped, homodromic deflection will not occur, this greatly reduces the impact effect that a section pull rod deflects to whole pull rod amount of deflection,
Prevent pull rod pin shaft because stress is larger cut fixing bolt cause pin shaft be detached from pull rod accident generation, effectively increase drawing
The safety of bar operation.
Based on the above method, the invention proposes the improvement structure of a kind of gate and trash rack pull rod, which is in lock
Using the pin shaft connection for being mutually perpendicular to arrangement between the upper section pull rod and lower section pull rod that door and trash rack are connected；The lower section of bottommost
Pull rod is connect with the lifting lug of gate or trash rack by pin shaft.
Wherein, lower section pull rod by bottom plate, perpendicular platform sling, web, lockplate, locking stiffening plate, top plate, perpendicular platform sling stiffening plate,
Horizontal platform sling and horizontal platform sling stiffening plate are welded to form；Wherein, the perpendicular platform sling stiffening plate of lower section pull rod is symmetrically welded on its perpendicular platform sling；
The horizontal platform sling stiffening plate of lower section pull rod is symmetrically welded on its horizontal platform sling.
Wherein, upper section pull rod is by top plate, perpendicular platform sling, lockplate, locking stiffening plate, perpendicular platform sling stiffening plate, horizontal platform sling and cross
Platform sling stiffening plate is welded to form；The perpendicular platform sling stiffening plate of upper section pull rod is symmetrically welded on its perpendicular platform sling；Upper the horizontal of section pull rod is hung
Plate stiffening plate is symmetrically welded on its horizontal platform sling.
Further, the distance between horizontal platform sling stiffening plate outer rim of two outermosts of upper section pull rod is slightly less than lower section pull rod
The distance between top two most inner sides horizontal platform sling stiffening plate inner edge；Two outermost of top of upper section pull rod erects platform sling stiffening plate outer rim
The distance between be slightly less than two most inner side of lower part of lower section pull rod and erect the distance between platform sling stiffening plate inner edge.
Compared with prior art, the invention has the following beneficial effects:
(1) phase is made using the pin shaft connection for being mutually perpendicular to arrangement between the two section pull rods up and down that gate and trash rack are connected
The direction deflected between two section pull rods up and down even is vertical, wherein a section pull rod is because such as being locked beam displacement, lock by environmental factors
Situations such as vibration of door or trash rack, deflects, and coupled pull rod will receive the power vertical with deflection direction, increases it
Homodromic deflection will not occur for the frictional force between pin shaft and pull rod hole wall, this greatly reduces a section pull rod and deflects to whole
The impact effect of body pull rod amount of deflection, it is therefore prevented that pull rod pin shaft because stress is larger cut fixing bolt cause pin shaft be detached from pull rod
The generation of accident effectively increases the safety of pull rod operation；
(2) the distance between the horizontal platform sling stiffening plate outer rim of two outermosts that pull rod is saved on is slightly less than the top two of lower section pull rod
The distance between most inner side horizontal platform sling stiffening plate inner edge is embedded in the top of lower section pull rod convenient for upper section pull rod lower part；
(3) two outermost of top that pull rod is saved on is erected the distance between platform sling stiffening plate outer rim and is slightly less than under lower section pull rod
Two most inner side of portion erects the distance between platform sling stiffening plate inner edge, convenient for saving the top of pull rod in the insertion of lower section pull rod lower part.
