Description
Technical field
The utility model is related to dumper field, is a kind of backdoor hydraulic locking device of dumper.
Background technology
Dumper conveying medium widely, as coal, iron ore, the cubic metre of earth and stone, sand material, sludge, dregs etc., transport
The common automatic latch hook mechanisms such as dry matter, loose material can meet seal request.But the powders such as sludge, dregs, wet matter, liquid material
It can be omitted in transit at back door and base plate, there is serious secondary pollution, seriously pollute urban environment.
The content of the invention
The purpose of this utility model is to provide for a kind of backdoor hydraulic locking device of new dumper.
What the utility model was realized in：The backdoor hydraulic locking device of a kind of dumper, it is characterized in that rubber strip is solid
Back door surrounding is scheduled on, hydraulic jack is below upper plate, and the latch hook by oil cylinder bearing pin respectively with both sides is hinged, latch hook set
In rotating shaft, rotating shaft is fixed tightly on lock hook seat, and lock hook seat is welded on the rear frame of base plate rear lower, and axle sleeve is enclosed within solid sleeve block
On, Gu sleeve block is fixed on the lower end at back door.
By adopting the above-described technical solution, the sealing problem around back door and compartment is solved, the hydraulic energy lock of use
Clamp force is big, locking effect is good, while retaining mechanism is arranged in below base plate, buildup will not be produced during loading and unloading.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is hydraulic jack assembling structure schematic diagram of the present utility model.
In figure：1st, hydraulic jack；2nd, latch hook；3rd, oil cylinder bearing pin；4th, rotating shaft；5th, axle sleeve；6th, upper plate；7th, rear frame；
8th, rubber strip；9th, back door；10th, lower shoe；11st, solid sleeve block；12nd, lock hook seat.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
In fig. 1 and 2, rubber strip 8 is fixed on the surrounding of back door 9, and hydraulic jack 1 passes through oil below upper plate 6
Cylinder bearing pin 3 is hinged with the latch hook 2 of both sides respectively, and latch hook 2 is enclosed within rotating shaft 4, and rotating shaft 4 is fixed tightly on lock hook seat 12, lock hook seat 12
On the rear frame 7 for being welded in the rear lower of base plate 10, axle sleeve 5 is enclosed within solid sleeve block 11, Gu sleeve block 11 is fixed under back door 9
End.
When the inlet valve button for pressing hydraulic jack 1, the piston rod of hydraulic jack 1 protrudes through oil cylinder bearing pin 3 and drives two
The latch hook 2 of side 4 laterally rotates around the shaft and gradually hooks axle sleeve 5, and tensing back door is deformed rubber strip 8 so as to after reaching
Door sealing, locking purpose.
Conversely, when the oil return valve button for pressing hydraulic jack 1, the piston rod of hydraulic jack 1 is retracted through the band of oil cylinder bearing pin 3
The latch hook 2 of dynamic both sides 4 turns to the inside around the shaft and gradually leaves axle sleeve 5, and unclamping back door restores the deformation of rubber strip 8, when
Back door opening just can discharging after carriage lifting.
