Description
Technical field:
This utility model relates to the cat ladder of a kind of adjustment height, a kind of structure fixing with crane bolt.
Background technology:
Cat ladder on crane is installed at present, it is that the top of cat ladder is fixed by bolts on upper mounting plate, bottom is fixed by bolts on lower platform, but owing to cat ladder size is bigger, manufacture process has error, deformation in transportation in addition, during in-site installation, always there will be cat ladder length a little or shorter, horizontal range is a little less or more, the bolt hole that installer bores on mounting platform and cat ladder is always to not going up, only slice off redundance again to weld, redrilling assembles again, its shortcoming is, one is that weldering trouble is cut at scene, redrilling increases workload, have a strong impact on the presentation quality of installation effectiveness and crane.
Summary of the invention:
Task of the present utility model be propose a kind of energy up and down, the adjustment of position, improve the cat ladder of adjustment height on a kind of crane of installation effectiveness.
Task of the present utility model so completes, it includes cat ladder body and railing, it is characterized in that: the upper end of cat ladder body is fixed with upper mounting plate by fixing bolt, there is a vertical adjustment plate in the ending vertical direction of cat ladder body, strip hole is had on the plate face of described vertical adjustment plate, the inward at both ends folding of adjustment block has the sliding tray that vertical adjustment plate can be made to slide, the front of described adjustment block is had the strip hole corresponding with vertical adjustment plate and is fixed by vertical adjustment bolt, the lower horizontal direction of adjustment block have bolt hole corresponding with the bolt hole on cat ladder base after fixed by horizontal adjusting bolt, described cat ladder base is welded on lower platform.Along both sides, cat ladder direction equipped with railing, the inclined shape of cat ladder body is fixed with upper mounting plate.
The advantages such as it is low that this utility model has the effect that the technical program solves cat ladder installation effectiveness, improves installation effectiveness, it is achieved that welding during crane safety, easily installs, time saving and energy saving.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is the structural representation of railing and cat ladder；Fig. 3 is adjustment block structural representation；Fig. 4 is Fig. 3 A-A direction structure schematic diagram.
Drawing illustrates: 1, lower platform, 2, cat ladder base, 3, horizontal adjusting bolt, 4, vertically adjust bolt, 5, adjustment block, 6, cat ladder body, 7, railing, 8, upper fixing bolt, 9, upper mounting plate, 10, vertical adjustment plate, 11, strip hole, 12, sliding tray.
Detailed description of the invention:
Embodiment is described in detail in conjunction with the figures above, as shown in Figure 1, the upper end of cat ladder body 6 is fixed with upper mounting plate 9 by fixing bolt 8, along both sides, cat ladder direction equipped with railing 7, it is effectively protected the safety of upper and lower cat ladder personnel, furtherly, the inclined shape of cat ladder body 6 is fixed with upper mounting plate, there is a vertical adjustment plate 10 in the ending vertical direction of cat ladder body, strip hole 11 is had on the plate face of described vertical adjustment plate, the inward at both ends folding of adjustment block 5 has the sliding tray 12 that vertical adjustment plate can be made to slide, the front of described adjustment block is had the strip hole corresponding with vertical adjustment plate and is fixed by vertical adjustment bolt 4, the lower horizontal direction of adjustment block have bolt hole corresponding with the bolt hole on cat ladder base 2 after fixed by horizontal adjusting bolt 3, described cat ladder base 2 is welded on lower platform 1.
Cat ladder body and vertical adjustment plate can be made an entirety during making, it is not necessary to connector, the most firm.
When workman installs cat ladder, the upper end first using fixing 8 cat ladder bodies 9 of bolt is fixed on upper mounting plate 9, adjust and the upper-lower position of vertical adjustment plate 10 with adjustment block 5 according to cat ladder vertical height, during adjustment, adjustment block is moved up and down along sliding tray at vertical adjustment plate, can compensate because of foozle and and the height error that causes, fix with the vertical bolt 4 that adjusts after adjusting height, the adjustment of horizontal direction can be adjusted by the bolt hole of adjustment block bottom, adjust horizontal level leveling screw to fix, then all bolts are tightened, thus solve the error in existing cat ladder installation process, achieve Fast Installation.
