Abstract
The utility model discloses a compression type garbage truck collection box locking device. The device comprises an oil cylinder and a limiting plate, wherein the fixed end of the oil cylinder is hinged with the upper end of a locking rod; the oil cylinder and the locking rod are slidingly connected with a sliding groove of an oil cylinder fixed seat; the locking rod can longitudinally slide along the sliding groove under the action of the oil cylinder; the movable end of the oil cylinder is fixed to a collection box through a fixing device; the limiting plate has the effects of guiding and limiting on the locking rod; an edge plate is arranged at the tail end of the locking rod; the inclination of the edge plate is the same with that of a wedge block fixed to the collection box; the edge plate can be interlocked with the wedge block in the vertical direction in a staggered way. The limiting plate is fixed to a dustbin. The device guarantees the sequence of locking motion and lifting motion in terms of structure, does not need an additional sequence control valve, reduces the cost, and meanwhile simplifies the structure and the operation of a hydraulic control system.
Description
Technical field
The utility model relates to a kind of compression type garbage truck collecting box latching device.
Background technology
Rear-loading compression type garbage truck has obtained extensive application in environmental sanitation department.The waste-skip rear portion of this kind of structure is provided with collecting box, when the outer refuse collection of car is entered in car, needs first collecting box and garbage box reliably to be locked; While dumping rubbish, need first remove locking, collecting box is lifted.The structure of existing collecting box is all two oil cylinders for lifting of left and right sides configuration, configures two oil cylinders for locking simultaneously, and lifting and the locking function of realizing collecting box need 4 oil cylinders altogether.
Utility model content
The deficiency existing for solving prior art, the utility model discloses a kind of compression type garbage truck collecting box latching device, the locking function of collecting box is realized by elevating ram, only needs 2 oil cylinders just can complete lifting and the locking function of collecting box, has saved two oil cylinders.The utility model has guaranteed locking action and lifting action order between the two from structure, has simplified hydraulic control system, and a kind of collecting box latching device of simple in structure, easy to operate, low cost of manufacture is provided.
For achieving the above object, concrete scheme of the present utility model is as follows:
A kind of compression type garbage truck collecting box latching device, comprise oil cylinder and positioning plate, the fixed end of oil cylinder and the upper end of locking lever are hinged, the chute sliding block joint of both hinged places and oil cylinder fixing base, locking lever can slide up and down along chute under oil cylinder effect, the movable end of oil cylinder is fixed on collecting box by anchor fitting, and positioning plate plays guide and limit to locking lever;
The end of described locking lever is provided with sword plate, and its gradient is consistent with the voussoir being fixed on collecting box, the interlock that can interlock of sword plate and voussoir in the vertical direction.
Described positioning plate is fixed on rubbish container.Oil cylinder fixing base is fixed on rubbish container.
In described positioning plate, be provided with the guide groove matching while sliding with locking lever.
During collecting box lifting, oil cylinder is extrapolated under hydraulic efficiency pressure system effect, and oil cylinder fixed end, along sliding to top limit position on permanent seat chute, pulls locking lever to move up simultaneously, and the sword plate of locking lever end and voussoir are thrown off, lock release; Oil cylinder continues to release, and its movable end outwards promotes collecting box, realizes the lifting of collecting box.
During collecting box locking, slide to the extreme lower position of oil cylinder fixing base chute under the upper end of oil cylinder fixed end drive locking lever, locking lever is moved down by positioning plate guiding, its sword plate and voussoir interlock, and collecting box is locked.
The beneficial effects of the utility model:
The locking function of collecting box is realized by elevating ram, does not need independent locking cylinder.The utility model has guaranteed from structure the sequencing that locking action and lifting are moved, and does not need extra sequence control valve, and when reducing costs, the structure of hydraulic control system and operation are also simplified.
Accompanying drawing explanation
Fig. 1 the utility model collecting box lifting structures schematic diagram;
Fig. 2 the utility model collecting box lifting structures schematic diagram;
In figure, 1. oil cylinder fixing base, 2. oil cylinder, 3. locking lever, 4. positioning plate, 5. voussoir, 6. collecting box, 7. rubbish container.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1-2, a kind of compression type garbage truck collecting box latching device, package unit comprises oil cylinder 2, oil cylinder fixing base 1, locking lever 3, positioning plate 4 and voussoir 5.The end of locking lever 3 is provided with sword plate, and its gradient is consistent with voussoir 5, the interlock that can interlock of both in the vertical directions.Positioning plate 4 is fixed on rubbish container 7, and locking lever 3 is played to guide and limit, and voussoir 5 is fixed on collecting box.The fixed end of the upper end of locking lever 3 and oil cylinder 2 is hinged, and the chute sliding block joint of both hinged places and oil cylinder fixing base 1 can slide up and down along chute under oil cylinder 2 effects.
During collecting box locking, the piston rod of oil cylinder 2 is in retracted state, and its fixed end drives the extreme lower position that slides to oil cylinder fixing base 1 chute under locking lever 3 upper ends.Locking lever 3 is moved down by positioning plate 4 guiding, its sword plate and voussoir 5 interlocks, and collecting box 6 is locked.
Otherwise oil cylinder 2 fixed ends, along sliding to top limit position on oil cylinder fixing base 1 chute, drive locking lever 3 to move up, the sword plate of locking lever 3 ends and voussoir 5 are thrown off, lock release, and oil cylinder 2 movable ends are extrapolated, and collecting box 6 is picked up.
