Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the schematic diagram of another structure and its use state of the invention.
Specific embodiment
Embodiment 1: as depicted in figs. 1 and 2, one kind crossing crossing device convenient for precasting yard portal jib crane, including chooses fork structure
With activity cover plate structure, portal jib crane is located on track 4 by the rail wheel 19 of crane roll-out tray 5 and its lower end, in which:
It chooses fork structure: making the conducting wire of portal jib crane for provoking to be covered on portal jib crane and set the activity cover plate 12 of 7 upper end of duct
10 can smoothly pass through from activity cover plate lower end.Choose fork structural support by connecting bracket 2, fixing seat 3, stiffening plate 11, choose fork 8 and
Oblique reinforcing bar 9 is formed.It chooses fork to be arc-shaped, chooses vent and set in duct in portal jib crane.The front and rear portions for choosing fork, which are lower than, to be covered on
Portal jib crane sets the lower end surface of each activity cover plate of duct upper end.
The middle part for choosing fork is higher than the upper surface that portal jib crane sets duct.When each activity cover plate is located at the middle part for choosing fork,
The space that activity cover plate is opened can be such that connecting bracket and conducting wire passes through.The longitudinal axis for choosing fork and portal jib crane sets duct
Longitudinal axis it is parallel.The front and rear portions for choosing fork are bent downward, and end in contact chooses fork under the cover plate with activity
Forward and backward end is inclined-plane, is pushed up upwards in order to choosing the front and rear portions of fork and holds activity cover plate.
The upper end of two connecting brackets in spacing distance setting duct side is set with portal jib crane is located at by fixing seat
The side of crane roll-out tray be connected.The middle part of connecting bracket is connected to oblique with middle part lower end that is choosing fork.Even
The front for connecing bracket folds into downward vertically.Oblique reinforcing bar is equipped between the front end of connecting bracket and the front lower ends for choosing fork, to add
The intensity between the front of fork and connecting bracket is chosen by force.Stiffening plate is equipped between the front end of connecting bracket, for reinforcing two connections
Bonding strength between bracket and the lower end for choosing fork.The conducting wire of portal jib crane is between connecting bracket.Positioned at connecting bracket it
Between conducting wire can to pass through conducting wire fixing clip 1 with connecting bracket fixed.
Activity cover plate structure: for cooperating the upper surface chosen fork structure opening and closing portal jib crane and set duct.Activity cover plate
Structure is constituted by fixing bottom plate 18, fixing axle ear 14, hinge axis 13 and activity cover plate 12.Fixed bottom plate is fixed on outboard end
Portal jib crane set on the bank of duct.The upper surface of fixed bottom plate is equipped with fixing axle ear in spacing distance.Activity cover plate
Rear end is linked between two adjacent fixing axle ears by hinge axis.The front of activity cover plate rides upon gantry of inner end
Crane is set on the bank 6 of duct, so that so that activity cover plate is opened and closed portal jib crane from front as axis using hinge axis sets duct
Upper end.The activity cover plate is rectangular strip steel plate, and several piece activity cover plate carries out to cover side by side sets duct in portal jib crane
Upper surface.Gap is equipped between the adjacent activity cover plate, in order to avoid interact.
When portal jib crane crosses crossing, choose fork structure with portal jib crane move ahead or retreat, positioned at choose fork structure on choosing fork before,
Rear end, which contacts to carry out to set first, sets the activity cover plate of duct upper end side in portal jib crane, with moving ahead or retreating for fork is chosen, chooses
Fork provokes each activity cover plate from its front by each upwards, is covered for the conducting wire between connecting bracket by each activity
The lower end of plate, each activity cover plate loses support force after choosing fork, falls closing using hinge axis as axis again and closes portal jib crane and sets
The upper end of duct, for vehicle pass-through.
As shown in Fig. 2, unlike 1 structure of embodiment: the upper surface for choosing fork is transversely provided in spacing distance
Beaming roller slot 15, beaming roller slot inner shaft are equipped with beaming roller 16, and the both ends of beaming roller can set roll shaft 17, and the both ends of beaming roller are located at axis by roll shaft axis
In roller slot, is contacted so that the upper surface for choosing fork be made to become bearing element with the CONTACT WITH FRICTION of each activity cover plate, be more convenient for choosing fork
Each activity cover plate is provoked upwards from its front by each.Remaining structure is identical, therefore is not repeated.
In short, the present invention can make portal jib crane carry out lid gantry crane automatically quickly through crossing and iron plate under not parking state
Vehicle sets duct, has simple and practical in structure, time saving and energy saving, low manufacture cost, using effect and the good advantage of safety.
