Abstract
The utility model provides a connecting structure for movable step adjusting plates and steel angles of balance bars for wharfs. The connecting structure comprises the adjusting plates. The adjusting plates are mounted under horizontal movable step pedals and are perpendicular to the movable step pedals, each adjusting plate is inserted in a space between a corresponding pair of steel angles of the balance bars, shaft holes are formed in insertion matched positions of the adjusting plates and the steel angles of the balance bars, shaft sleeves are mounted in the shaft holes, the lengths of the shaft sleeves are equal to the sums of the wall thicknesses of the adjusting plates and the steel angles of the balance bars, and fastening bolts are mounted in the shaft sleeves, so that the adjusting plates can be fixed to the steel angles of the balance bars. The connecting structure has the advantages that joints of the connecting structure are not easy to rust and are abrasion-resistant and flexible, and excellent safety can be guaranteed.
Description
Technical field
The utility model device belongs to About Construction Technology of Steel Configuration field, is specifically related to the mark time syndeton of adjustable plate and balancing pole angle steel of a kind of activity for harbour.
Background technology
Steel drawn bridge is generally used for harbour walk, and in steel drawn bridge design, when design lowest stage, the sidewalk gradient is greater than 1/4 and activity should be set mark time.In traditional handicraft, the connected mode of movable mark time adjustable plate and balancing pole angle steel, for to mark time perforate on adjustable plate and balancing pole angle steel, is used bolt, nut to be fixedly connected with, the double rotating shaft of doing adjustable plate of bolt.
Because steel drawn bridge working region is with the humid air, steel work easily produces corrosion.In traditional handicraft, adjustable plate directly contacts with bolt, and the wearing and tearing to bolt in operation process are larger, and connecting portion is easy to rust and extremely causes adjustable plate and can not rotate with respect to axle and cause activity to be marked time in running, occurring stuck phenomenon.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provide a kind of connecting portion be difficult for getting rusty, wear-resisting, flexible and ensure the mark time syndeton of adjustable plate and balancing pole angle steel of safe activity.
The utility model solves the technical scheme that its technical problem adopts:
The mark time syndeton of adjustable plate and balancing pole angle steel of a kind of activity, the activity that includes the level of the being arranged on pedal below of marking time, with the activity vertical adjustable plate of pedal of marking time, it is characterized in that: described adjustable plate inserts between a pair of balancing pole angle steel, and all have axis hole at the insertion matching part of adjustable plate and balancing pole angle steel, axle sleeve is installed in axis hole, the wall thickness sum of the length of axle sleeve and adjustable plate and balancing pole angle steel is isometric, fastening bolt is installed in axle sleeve adjustable plate and balancing pole angle steel are fixed.
Press such scheme, described axle sleeve material is acid bronze alloy, and axle sleeve and adjustable plate and balancing pole angle steel are welding manner and fix.
Press such scheme, described fastening bolt is stainless steel bolt, and stainless steel nut is installed on fastening bolt, and the contact surface of stainless steel nut and balancing pole angle steel is provided with packing ring.
The beneficial effects of the utility model are:
1,, owing to using copper standard shaft cover to separate between adjustable plate and bolt, avoided connecting portion in traditional construction technology to occur that rust extremely causes the stuck phenomenon that turns round.
2, copper standard shaft cover contacts littlely compared with adjustable plate and bolt coefficient of contact friction with bolt as the surfaces of revolution, and the abrasion condition of bolt is had to very big improvement.
3, bolt " axle part " is arranged in copper standard shaft cover, has improved running environment.

Fig. 1 is the scheme of installation of the utility model embodiment.
Fig. 2 is the cross section A-A structural representation of the utility model embodiment.
Fig. 3 is B portion enlarged diagram in Fig. 2 of the utility model embodiment.
In figure: 1, the activity pedal of marking time, 2, adjustable plate, 3, balancing pole angle steel, 4, fastening bolt, 5, axle sleeve,
6, packing ring.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
The mark time syndeton of adjustable plate and balancing pole angle steel of activity as shown in Fig. 1 Fig. 2 Fig. 3, the activity that includes the level of being arranged on pedal 1 below of marking time, with the activity vertical adjustable plate 2 of pedal 1 of marking time, described adjustable plate 2 inserts between a pair of balancing pole angle steel 3, and all have axis hole at the insertion matching part of adjustable plate 2 and balancing pole angle steel 3, axle sleeve 5 is installed in axis hole, the wall thickness sum of the length of axle sleeve 5 and adjustable plate 2 and balancing pole angle steel 3 is isometric, and the interior installation fastening bolt 4 of axle sleeve 5 is fixing with balancing pole angle steel 3 by adjustable plate 2.
In the present embodiment, described axle sleeve 5 materials are acid bronze alloy, and axle sleeve 5 is welding manner with adjustable plate 2 and balancing pole angle steel 3 and fixes.
In the present embodiment, described fastening bolt 4 is stainless steel bolt, and stainless steel nut is installed on fastening bolt 4, and the contact surface of stainless steel nut and balancing pole angle steel 3 is provided with packing ring 6.
More than explanation is only Application Example of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalence of therefore doing according to the utility model claim changes, and still belongs to protection domain of the present utility model.
