Description
Technical field
the invention belongs to waste-skip manufacturing technology field, be specifically related to a kind of sealing locking carriage back door of garbage truck device, can be used for various back door of garbage truck device.
Background technology
waste-skip is used for collecting, loading and transport house refuse, and by the garbage-compressing of loading, crushing, its density can be increased, volume-diminished, greatly increase the efficiency of refuse collection and transport.Need in transportation to keep back door to close, prevent rubbish from leaking, after vehicle arrives garbage disposal plant, back door is opened, rubbish is unloaded.Therefore, enough angles should be opened in back door, ensure leak tightness when closing again.
the carriage back door of garbage truck design of prior art generally includes manual mode and automated manner two kinds:
the first manual mode: comparatively ripe manual back door catch gear is ratchet device, is widely used in the back door locking of lifting hook.Rotating ratchet mechanism, the pull bar that connects between latch hook with compartment extends by forward and reverse thread rod, make latch hook clickwise, back door is by guiding cylindrical void glide downwards, and latch hook and lock shaft unclamp, compartment of tumbling, back door will be opened automatically, sewage can be sealed in compartment by which completely, good sealing effect, but troublesome poeration.Another kind of manual mode is door latch type, and its operation is inconvenient, dense water is poor, progressively by market.
the second automated manner: automatic rear door catch gear is because of vehicle difference, and its outward appearance is also little the same, but its principle is roughly the same.For rear-loading compression type garbage truck, enabling oil cylinder stretches out and back door (packer) is first upwards slided by guiding cylindrical void, and latch hook and lock shaft are thrown off, and enabling oil cylinder continues to stretch out, and back door will be opened thereupon.The thrust of this mode to the sealing joint strip between compartment and back door leans on the disc of latch hook self or inclined-plane to realize, therefore the amount of feeding is compressed limited, can not sewage be sealed in compartment, water receiving tank be installed in back door (packer) lower end usually and avoid sewage in transportation to spill problem.But, still there is secondary pollution hidden danger when road bump.Mostly adopt enabling oil cylinder, pilot hole, latch hook etc. in automated manner, mostly latching device is the improvement to latch hook place simultaneously, does not solve the problem that back door glides.
Summary of the invention
the present invention seeks to: provide one feasible and failure-free back door structure, shutter door success ratio is high and carriage back door of garbage truck device is locked in the sealing effectively preventing envelope back door from gliding.
technical scheme of the present invention is: a kind of sealing locking carriage back door of garbage truck device, comprise envelope back door framework, be located at the envelope back door on the framework of described envelope back door, and the back door catch gear that two are located at described envelope back door framework and both sides, described envelope back door respectively, two symmetrically arranged oblique waist shaped hole seats are respectively equipped with on top, framework both sides, described envelope back door, described envelope rear door frame top of the trellis be provided with two go out rod-type positional cylinder, described pair goes out rod-type positional cylinder two ends and is respectively equipped with a wedge, and described wedge is parallel with the oblique waist shaped hole described oblique waist shaped hole seat being positioned at below, between two oblique waist shaped hole seats, be provided with a rotation ear simultaneously, described rotation ear one end is pumped along oblique waist shaped hole by bearing pin, the described rotation ear other end is fixedly connected with respective side top, described envelope back door.
as preferred technical scheme, described back door catch gear comprises the locking cylinder being located at described envelope back door framework and both sides, described envelope back door, hinged in the middle part of the lower end of described locking cylinder and described envelope back door framework respective side, the extension bar upper end of described locking cylinder and described envelope back door respective side upper articulation.
as preferred technical scheme, described back door catch gear also comprises the lock pin being located at framework bottom, described envelope back door, and to be located on described envelope back door and the latch hook be equipped with described lock pin.
as preferred technical scheme, stretch out direction, the direction of tilt of oblique waist shaped hole and the cheicers oblique line directions of latch hook of described locking cylinder form three parallel lines structures, normally latch when ensureing that envelope back door is closed.
as preferred technical scheme, outside described envelope back door, be arranged with sealing joint strip, after ensureing the closedown of envelope back door, sealing is firm.
as preferred technical scheme, be positioned at outside two oblique waist shaped hole seats be fixed with an anti-drop block respectively at described bearing pin two ends.
advantage of the present invention is:
1. the present invention adopt two go out rod-type positional cylinder, its two ends wedge coordinates with the oblique waist shaped hole on the framework of envelope back door, can not move down when guarantee envelope back door is opened, and raising shutter door success ratio;
2. the present invention adopts three parallel lines structures, namely locking cylinder stretch out direction, the direction of tilt of oblique waist shaped hole and latch hook cheicers oblique line directions parallel, normally latch when ensureing that envelope back door is closed, improve the reliability of back door catch gear, and the accuracy of lock shaft and latch hook cooperation;
3. locking cylinder of the present invention and two go out rod-type positional cylinder be all located at outside compartment casing, easy access.
