Four steel wheel seat structures of described every side all adopt steel plate or channel-section steel pad to put down.
Advantage of the present invention is: this cradle structure is simple, light and handy, assembly and disassembly are quick; Can along the bridge floor traveling, be convenient to the carrying, the keeping, cantilever height is adjustable, compliance is strong; Structure is segmented to combine, and assembling is simple and interchangeability is strong.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention general assembly front view;
Accompanying drawing 2 is an embodiment of the invention general assembly vertical view;
Accompanying drawing 3 is an embodiment of the invention truss agent structure sketch map;
Accompanying drawing 4 is an embodiment of the invention steel wheel seat structure sketch map.
The specific embodiment
Through embodiment characteristic of the present invention and other correlated characteristic are done further explain below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
, always represent respectively with reference to label 1-13 to shown in Figure 4 like Fig. 1: truss agent structure 1, hanging system 2, support and connection are 3, tail balancing weight system in equilibrium 4, Running System 5, upper cantilever i iron 6, square steel pipe 7, gripper shoe 8, wheel carrier 9, copper sheathing bearing 10, main shaft 11, roller 12, pin connect hole 13.
Referring to Fig. 1-4, the basic structure of cradle structure can be divided into truss agent structure 1 according to the purposes difference among the present invention, and hanging system 2, support and connection are 3, tail balancing weight system in equilibrium 4, Running System 5 five major parts.
1 truss agent structure 1
2 hanging systems 2
3 support and connection are 3
Support and connection are that 3 main materials are selected angle steel for use, divide size two kinds of specifications.Be applied to connect between the truss, the ramuscule support forms the main stabilizing member of Hanging Basket frame construction.Big bracing frame forms the globality of a long unit of 6m.Size bracing frame appearance and size is different, therefore can not be general, all select for use the steel bushing bolt to be connected but support and connection are 3 type of attachment with the truss hole, connecting bolt is equal can exchange general.
4 tail balancing weight system in equilibriums 4
Tail balancing weight system in equilibrium 4 is mainly used in the platform that Hanging Basket overturning or slip resistance analysis safety is put the ballast material.Its material selection 100 * 50 * 5mm square steel pipe is hung rod member and is all adopted the flanged plate bolt to connect up and down, and platform structure adopts No. 10 common channel-section steels to be connected with the square steel pipe bolt.The suspension rod installation dimension all accomplishes to exchange.
5 Running Systems 5
Running System 5 is mainly whole the moving of Hanging Basket assembling back block construction and uses, and is installed on a plurality of steel wheel seat structures of the flanged plate both sides of truss agent structure 1 bottom surface for symmetry.Wherein the steel wheel seat structure includes one and is used for and gripper shoe 8 that the bottom surface bolt of truss agent structure 1 is fixing; Gripper shoe 8 lower ends are welded with two parallel wheel carriers 9; The other end of wheel carrier 9 is respectively equipped with corresponding copper sheathing bearing 10; Be set with a main shaft 11 in two copper sheathing bearings 10, be fixed with the roller 12 of a diameter 100mm on the main shaft.Adopting the reason of copper sheathing bearing 10 is that environment is abominable in bridge construction; The plain bearing easy fault; And 10 body structures of copper sheathing bearing cause resistance big, and especially the confficient of static friction and the coefficient of kinetic friction differ bigger, make to have static easily, fixing characteristic.The grease of should annotating during the assembling of this steel wheel seat structure guarantees the lubricated parts depreciation that reduces, all can dismounting for ease of maintaining whole parts.
The structure of the Hanging Basket of more than describing in detail among the present invention to be designed, below above-mentioned apparatus structure require to describe for the assembly manipulation of this hanging basket:
(1) must be familiar with the brief introduction of manual inner structure before the Hanging Basket operation.Specify concrete administrative staff, solution structure master assembly unit order, use and deposit and should take necessary safeguard measure, to guarantee the intact of cradle structure part.
(2) Hanging Basket is on viaduct during spelling, and the Suspension hanger device should be selected existing railway line bridge side to have on the job platform to install.
(3) spelling can take artificial passing or winch dragging to move forward along bridge after accomplishing 6 meters long Hanging Baskets of a cell cube.
(4) Running System 5 of each Hanging Basket block construction has disposed 8 steel wheels and has supported bridge floor.In order to guarantee that steel wheel bears Hanging Basket deadweight walking simultaneously, must every side four wheels pad is flat, the flat material of pad adopts steel plate or greater than No. 20 channel-section steels.Must transition level up when especially wheel is through bridge end shrinkage joint.
(5) instrument, concrete particle, the foreign material when preventing that personnel from constructing fall, and the bottom panel of hanging system 2 and side panel all adopt the wooden forms sealing of 18 millimeters thick.The Dense mesh screen sealing is adopted in 2 meters high tops of side panel.Fixing means is taked to hole on the plank, the colligation of 4 millimeters iron galvanized wires.To stride railway division when construction even more important last in this requirement.
(6) Hanging Basket before hang square steel pipe 7 and must select 8.8 grades M20 high-strength bolt pin joint with the cover connecting bolt, bolt quantity one termination must not be less than 2, forbids to adopt other materials to replace usefulness.
(7) concrete block of afterbody ballast material selection criteria module weight comes ballast, can carry, and weight is clear.Require to lean on to the greatest extent the afterbody outside to stack, make every effort to even distribution.Forbid the material of irregular size weight to be stacked carelessly and make the stable equilibrium ballast.
