A kind of conduction rack
Technical field:
The present invention relates to the conduction rack on a kind of crane.
Background technology:
Conduction rack on existing crane is Site Welding, size to contrast crane slip up line position and weld, and workman, after installing crane mainframe, stands in crane beam welding cart conduction rack up, welding process difficulty is big, and slightly imprudence is easy for bringing out the generation of personnel's falling accident.
Summary of the invention:
The task of the present invention is to propose one to reduce overhead welding, stops a kind of conduction rack that accident occurs.
The task of the present invention so completes, it is characterized in that: fixing plate is screwed the side at crane girder, fixing plate is fixed with outer montant, the front of described outer montant has the strip hole that slide bolt can be made to slide, the lateral surface of outer montant is provided with screwed hole, the front mantle fiber of described interior montant is equipped with slide bolt, the side of interior montant is provided with groove, interior montant it is set with in outer montant, fixed with fixing bolt by the groove of screwed hole thereon Yu interior montant side, side bottom described interior montant is welded with outer cross bar, the front of outer cross bar has strip hole, it is equipped with interior cross bar in outer cross bar to be fixed by the slide bolt of assembling on it, the afterbody of interior cross bar is equipped with slip.The angle of described outer cross bar and interior montant is welded with reinforcement.The screwed hole arranged outside outer cross bar with fixing bolt with its in the groove of cross bar side fix.
The present invention has the effect that the technical program can be fixed with bolt on the ground, mixes up the distance with slip on the ground, without electric welding, reduces work high above the ground, reduces the workload of workman, and reduce the generation of accident.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Drawing illustrates: 1, fixing plate, 2, outer montant, 3, slide bolt, 4, fixing bolt, 5, interior montant, 6, reinforcement, 7, outer cross bar, 8, interior cross bar, 9, strip hole.
Detailed description of the invention:
nullThe conduction rack four direction that the technical program relates to can regulate,When being transferred to suitable position,Only need to tighten four fixing bolts to be fixed,Specific embodiment is as shown in Figure 1,Conduction rack is by fixing plate 1、Outer montant 2、Interior montant 5、Outer cross bar 7 and interior cross bar 8 are constituted,Described fixing plate is screwed the side at crane girder,Fixing plate is fixed with outer montant 2,The front of described outer montant has the strip hole 9 that slide bolt 3 can be made to slide,The lateral surface of outer montant is provided with screwed hole,The front mantle fiber of described interior montant 5 is equipped with slide bolt 3,The side of interior montant is provided with groove,Interior montant it is set with in outer montant,Fixed with fixing bolt 4 with the groove of interior montant side by screwed hole thereon,Side bottom described interior montant is welded with outer cross bar 7,The angle of described outer cross bar and interior montant is welded with reinforcement 6,The front of outer cross bar has strip hole,The lateral surface of described outer cross bar is provided with bolt hole,Furtherly,It is equipped with interior cross bar 8 in outer cross bar to be fixed by the slide bolt of assembling on it,In order to make will not swing inside interior cross bar cross bar outside,By the fixing bolt of screwed hole that arranges outside outer cross bar with its in the groove of cross bar side fix,The afterbody of interior cross bar is equipped with slip.
First adjust the distance of slip on ground during work, the fixing bolt on outer montant and the slide bolt on interior montant is unclamped during adjustment, by sliding in the strip hole opened on the slide bolt montant outside of interior montant front assembling, adjust, lower position, adjust the position of left and right again, the adjustment of left and right is by sliding in interior cross bar cross bar outside, on, under, left, right four direction tightens slide bolt and fixing bolt after adjusting, fixing plate is screwed the side at crane girder, therefore decrease the workload of work high above the ground, eliminate Site Welding, thus saving man power and material.
