Abstract
The utility model discloses a novel landing leg device, it includes landing leg board, landing leg hydro -cylinder, bottom plate, and it still including a leg guard, antiskid plate, connecting bolt, bottom shrouding, props up the leg guard and overlaps in the outside of landing leg board, and the antiskid plate passes through connecting bolt to be fixed below the bottom plate, and its bottom is " people " font, and it has a hole to open on the bottom plate of a leg guard, and the bottom shrouding passes through the bolted cover outside the hole. The utility model discloses prevented that the stone that has flown from injuring the hydro -cylinder by a crashing object and piling up at the inside stone of landing leg with having reduced to the molding is similar with W -outrigger, and the wholeness is strong, has increased pleasing to the eye degree.
Description
Technical field
The utility model relates to a kind of support leg device of construction machinery and equipment, under high-risk environment, especially carry out the support leg device of the Engineering Robot of operation.
Background technology
In current construction machinery and equipment, a lot of equipment is all provided with support leg device, and it is played a supporting role at work.The structure of support leg device is as shown in Figure 6, Figure 7: supporting leg 1 is divided into fixed part above and moving part totally two parts below, the cylinder end of oil cylinder 2 is fixed on above supporting leg 1, rod end is hinged on below supporting leg 1, and support leg device realizes the connection with plant bottom case by bearing pin.The shortcoming of this kind of structure is: 1, in the presence of a harsh environment, and the stone flown up can be pounded oil cylinder or fly in supporting leg, and oil cylinder is fragile; 2, carrying out, under supporting leg support ground operating mode, easily breakking away with the supporting leg base plate of earth surface; 3, the connection of supporting leg inside is as the connection of: junction, top and the bottom, supporting leg and oil cylinder bearing pin all as shown in Figure 8 and bolt fastening structure, and this kind of connection mode easily loosens, and supporting leg easily ruptures.
Utility model content
The utility model provides a kind of support leg device, and it can prevent stone from damaging oil cylinder.Meanwhile, it can prevent supporting leg base plate from breakking away.In addition, it can also prevent supporting leg to rupture.
A kind of Novel support legs device of the utility model, it comprises outrigger plate, support oil cylinder, base plate, it also comprises supporting leg backplate, checkered plate, tie bolt, bottom shrouding, leg support protects sleeve-board is in the outside of outrigger plate, checkered plate is fixed on below base plate by tie bolt, be " people " font bottom it, the base plate of supporting leg backplate have a hole, bottom shrouding by bolted cover outside hole.
The utility model is by the outrigger plate at existing supporting leg outer cladding box-type, and prevent the stone flown up injure oil cylinder by a crashing object and decrease the stone being deposited in supporting leg inside, and moulding is similar to W-outrigger, globality is strong, adds aesthetics.Meanwhile, basis is novel is provided with a bolted bottom shrouding bottom supporting leg, like this when installing cylinder pipe and maintenance, need not dismantle outrigger plate extremely convenient.In addition, base plate installing checkered plate additional, is chevron pointing bottom checkered plate, and bolt connects checkered plate, when the road surface of easy damaged, can take off checkered plate, prevents from damaging road surface, when prevailing roadway works, just greatly can increase earth-grasping force, prevents from breakking away.

Detailed description of the invention
As shown in the figure, a kind of Novel support legs device of the utility model, it comprises outrigger plate 1, support oil cylinder 2, base plate, it is characterized in that: further comprising supporting leg backplate 5, checkered plate 8, tie bolt 9, bottom shrouding 10, supporting leg backplate 5 is enclosed within the outside of outrigger plate 1, and checkered plate 8 is fixed on below base plate by tie bolt 9, is " people " font bottom it, the base plate of supporting leg backplate 5 has a hole, and bottom shrouding 10 covers outside hole.
Supporting leg backplate 5 and the base plate weld together of this novel middle outer cladding, checkered plate 8 is fastened on base plate by tie bolt 9, form a complete entirety, a rectangular opening is had bottom supporting leg, bottom shrouding 10 is joined with bolts, be convenient to check at any time and cylinder pipe is installed, lining 7 is protected by be welded on supporting leg outer, protection bolt, expansion set tensioner connects bearing pin 12, bearing pin is free-running fit with protecting lining 7 outward, support oil cylinder rod chamber with on be connected pinned connection, rodless cavity is connected with lower bearing pin, overlap for free-running fit with both sides, oil cylinder stroke is designed to the oil cylinder distance of stretching out when supporting leg supports ground.Locating distance be supporting leg retract completely the state lifted time two junction distances, four supporting legs realize synchronously carrying out.
As a kind of improved procedure that this is novel, Novel support legs device also comprises tension mechanism, and tension mechanism comprises ringfeder 6, overcoat 7, bolt 11, bearing pin 12; Ringfeder 6 is enclosed within bolt 11, its external diameter press-in overcoat 7 internal diameter, the outer diameter contact of its internal diameter and bearing pin 12 reduced diameter section, ringfeder 6 is connected in aggregates with overcoat 7, supporting leg backplate 5 by bearing pin 12, former and later two bolts 11 are connected to the two ends, left and right of bearing pin 12 by the negative thread at front and back ringfeder 6 two ends, and are pressed on the outer face of ringfeder 6.During this is novel, leg pin junction all adopts Embedded expansion set structure, prevents slungshot to injure tie bolt by a crashing object, connects more tight, not easy fracture than old-fashioned bolt.
