A kind of soil-shifting pusher side shield auxiliary support mechanism, including gas spring 1, gas spring mounting base 2, support clamping apparatus 3
And shield attachment device 4, the gas spring mounting base 2 are weldingly fixed in the bull-dozer rack in soil-shifting pusher side shield, institute
It states shield attachment device 4 to be weldingly fixed on the inside of the shield of side, the cylinder barrel tail end of the gas spring 1 is hinged on gas spring by pin shaft
The piston rod top end of 2 bottom of mounting base, the gas spring 1 is hinged in shield attachment device 4 by pin shaft, the gas spring 1
Piston rod front be welded with link block 5, the fixed side on the piston rod on the lower of link block 5, the support card tipping
Setting 3 includes clamping portion 6 and interconnecting piece, and the whole clamping portion 6 is in cuboid-type, and the inside of cuboid clamping portion 6 is provided with groove
12, the 12 section semicircular in shape of groove, the groove 12 is adapted with the outer wall of 1 piston rod of gas spring, the interconnecting piece packet
Include 7,2 connecting plates 7 of connecting plate that 2 are fixed on 6 front of clamping portion front end be in link block 5 two sides and by pin shaft with
Link block 5 is hinged.The link block 5 is fixed on side opposite with clamping portion 6 on the piston rod of gas spring 1, when gas spring 1
When piston rod is rotated to level, clamping portion 6 is in the upside of piston rod, and link block 5 is fixed under the piston rod of gas spring 1
Side.The tail end of the clamping portion 6 withstands on the front end face of the cylinder barrel of gas spring 1 when soil-shifting pusher side shield is overturn to predetermined angle
On.At this moment, clamping portion 6 just produces supporting role with the common opposite side shield of the cylinder barrel of gas spring 1, it is ensured that side shield is at one
Biggish aperture stays open, and avoids side shield and falls under the effect of gravity.The groove 12 of the clamping portion 6 is in gas spring 1
The upper half of 1 piston rod of gas spring is fitted in when extending to longest.The two sides at the rear portion of the clamping portion 6 be respectively welded be fixed with it is convex
8 are played, described raised 8 section semicircular in shape.The shield attachment device 4 includes U-typed attachment base 9 and piston rod connector
10, the end of 9 both wings of U-typed attachment base is weldingly fixed on the inside of soil-shifting pusher side shield, the piston rod connector 10
It is weldingly fixed on the outer end face at 9 middle part of U-typed attachment base, the piston rod top end of the gas spring 1 is hinged on work by pin shaft
On stopper rod connector 10.Chamfering 11 is offered between the tail end and groove 12 of the clamping portion 6.
Artificial rotation soil-shifting pusher side shield, the piston rod of gas spring 1 are extracted out therewith, soil-shifting pusher side shield are opened to certain
After angle, the clamping portion 6 of support clamping apparatus 3 is rotated down under the effect of gravity, on the piston rod for entirely falling within gas spring 1,
The groove 12 of clamping portion 6 is bonded with the piston rod of gas spring 1, and at this moment, operator looses one's grip, and the tail end of clamping portion 6 is just withstood on
On the front end face of the cylinder barrel of gas spring 1, make at this point, clamping portion 6 just produces support with the common opposite side shield of the cylinder barrel of gas spring 1
With, it is ensured that side shield is stayed open in a biggish aperture, is avoided side shield and is fallen under the effect of gravity.
When needing to close soil-shifting pusher side shield, operator one lifts side shield, the other hand palm when held gas spring 1 on hand
Cylinder barrel front end, thumb press protrusion 8 separates the tail end of clamping portion 6 with the cylinder barrel front end of gas spring 1, and then falls side shield
It covering, in the shield descent of side, due to the buffer function of gas spring 1, side shield will not generate violent collision when closed, from
And the connecting portion of opposite side shield and support device and shield forms protective effect, failure rate is low, and service life is longer.
Compared with traditional support device, this soil-shifting pusher side shield auxiliary support mechanism can be protected ensuring soil-shifting pusher side
In the case that cover there can be sufficiently large aperture, less space is occupied.
The support of opposite side shield is formed since cylinder barrel end that supporting way is 6 end of clamping portion and gas spring 1 contradicts, because
This will not cause shield to fall as traditional support mechanism because of slideway groove abrasion deformation, and reliability is stronger, service life
It is longer.
The more convenient operator's thumb of this shape of the section semicircular in shape of protrusion 8, protrusion 8 is puted forth effort, so that operation
More convenient convenience.
The setting of U-typed attachment base 9 so that the stress point of side shield is assigned at the position that two are spaced a distance,
Stress more balances, more firm, while it is excessive to also avoid local pressure, so avoid local pressure it is excessive caused by office
Portion's deformation, damage.
The setting of chamfering 11 in pressing for operator's thumb so that depress, before the tail end of clamping portion 6 and the cylinder barrel of gas spring 1
End separates more smooth, avoids the tail end of clamping portion 6 and the cylinder barrel front edge contact position of gas spring 1 after long period of operation
The phenomenon that deformation, damage, practicability is stronger.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
