Description
Technical field
The invention belongs to garbage truck manufacturing technology field, and in particular to one kind sealing locking carriage back door of garbage truck device,
Available for various back door of garbage truck devices.
Background technology
Garbage truck is used to collecting, load and transport house refuse, and can be loaded into garbage-compressing, crush, make its density
Increase, volume-diminished greatly increases the efficiency of refuse collection and transport.Need to keep back door to close in transportation, prevent
Rubbish is leaked, and after vehicle reaches garbage disposal plant, back door is opened, rubbish is unloaded.Therefore, back door should can open foot
Enough angles, sealing when ensureing to close again.
The carriage back door of garbage truck design of prior art generally includes two kinds of manual mode and automated manner：
The first manual mode：More ripe manual back door retaining mechanism is ratchet mechanism, is widely used in lifting hook
Back door locking.Rotating ratchet mechanism, forward and reverse threaded rod extends the pull bar that couples between latch hook and compartment, makes latch hook up time
Pin is rotated, and gib block hole glide downwards are pressed at back door, and latch hook unclamps with lock shaft, and compartment of tumbling, back door will automatically turn on, and which can
Sewage is entirely sealed in compartment, good sealing effect, but troublesome poeration.Another manual mode is door latch type, and it is operated not
Just, dense water is poor, progressively by market.
Second of automated manner：Automatic rear door retaining mechanism is different because of vehicle, and its outward appearance is also less the same, but its principle is
Roughly the same.By taking rear-loading compression type garbage truck as an example, enabling oil cylinder stretches out back door (packer) is first upward by gib block hole
Slide, latch hook is disengaged with lock shaft, enabling oil cylinder continues to stretch out, and back door will be opened therewith.This mode is between compartment and back door
The thrust of sealing joint strip be to be realized by the disc or inclined-plane of latch hook itself, therefore the compression amount of feeding is limited, it is impossible to by dirt
Water-stop generally installs water receiving tank to avoid sewage in transportation from spilling problem in compartment in back door (packer) lower end.
However, still there is secondary pollution hidden danger in road bump.Simultaneously in automated manner mostly using enabling oil cylinder, pilot hole,
Latch hook etc., locking device is mostly that, to the improvement at latch hook, the problem of being glided to back door does not solve.
The content of the invention
The present invention seeks to：A kind of feasible and reliable back door structure is provided, shutter door success rate is high and effectively prevents railway carriage or compartment
The sealing locking carriage back door of garbage truck device that body back door glides.
The technical scheme is that：One kind sealing locking carriage back door of garbage truck device, including carriage body back door framework, if
Carriage body back door on the framework of the carriage body back door, and two be respectively arranged on carriage body back door framework and the carriage body back door two
The back door retaining mechanism of side, two symmetrically arranged oblique mounting hole seats are respectively equipped with carriage body back door framework both sides top,
At the carriage body back door frame roof provided with it is double go out rod-type positional cylinder, it is described it is double go out rod-type positional cylinder two ends be respectively equipped with one
Wedge, and the wedge is parallel with the oblique upper underlying oblique mounting hole of mounting hole seat, while oblique two
Provided with a rotation ear between mounting hole seat, described rotation ear one end is pumped by bearing pin along oblique mounting hole, institute
The rotation ear other end is stated with being fixedly connected at the top of the respective side of the carriage body back door.
As preferred technical scheme, the back door retaining mechanism includes being located at carriage body back door framework and the carriage body
The locking cylinder of back door both sides, the lower end of the locking cylinder in the middle part of the carriage body back door framework respective side with being hinged, the lock
The extension bar upper end of locking oil cylinder and the carriage body back door respective side upper articulation.
As preferred technical scheme, the back door retaining mechanism also includes the lock located at carriage body back door lower frame
Pin, and the latch hook being equipped with the carriage body back door and with the lock pin.
It is used as preferred technical scheme, under the closure state of carriage body back door, the stretching direction of the locking cylinder, oblique waist
The incline direction in shape hole and the cheicers oblique line directions of latch hook constitute three parallel lines structures, it is ensured that carriage body back door normally falls when closing
Lock.
As preferred technical scheme, sealing joint strip is provided with carriage body back door periphery, it is ensured that after carriage body back door is closed
Sealing is firm.
As preferred technical scheme, it is respectively fixed with the bearing pin two ends and on the outside of two oblique mounting hole seats
One anti-drop block.
It is an advantage of the invention that：
1. the present invention is using pair oblique mounting hole gone out on rod-type positional cylinder, its two ends wedge and carriage body back door framework
Coordinate, it is ensured that carriage body back door will not be moved down when opening, and improve shutter door success rate；
2. the present invention using three parallel lines structures, i.e. locking cylinder stretch out direction, oblique mounting hole incline direction with
And the cheicers oblique line directions of latch hook are parallel, it is ensured that carriage body back door normally latches when closing, the reliability of back door retaining mechanism is improved,
And the accuracy that lock shaft and latch hook coordinate；
3. the locking cylinder of the present invention and it is double go out rod-type positional cylinder on the outside of compartment casing, easy access.
