Put.
Background technology
Existing self-tipping type slag-soil truck back door uses chain self-locking, and chain one end is fixed with vehicle tail, the other end
Being connected with compartment afterbody latch hook, latch hook bearing pin is connected with compartment, can rotate freely.Its operation principle is: compartment is at power
Being rotated by bottom reversed pin under the effect in source and rise, chain shortens with afterbody back door, compartment latch hook distance, and latch hook is from recast
Opening voluntarily under with, Rear Door is opened under the effect of goods in deadweight and railway carriage or compartment voluntarily by car body top upset pin.Envelope
During decline, Rear Door is closed, chain tension under the effect of deadweight voluntarily by car body top upset pin, drives back door latch hook
Locked.There is following deficiency in the chain self-locking structure at this self-tipping type slag-soil truck back door: 1, chain is in transportation,
Back door when being impacted, chain easy fracture, cause locking lost efficacy；2, back door is poorly sealed, easy material leakage, brings the biggest city
Pollute.
Summary of the invention
It is an object of the invention to provide a kind of self-tipping type slag-soil truck rear door locking device, this device can solve existing from
Rear door locking device of unloading easily lost efficacy, and the problem that back door is poorly sealed.
In order to solve the problems referred to above, the technical solution used in the present invention is: this self-tipping type slag-soil truck rear door locking device
Including the latch hook for locking back door, described back door is hinged with top, compartment, described latch hook be arranged on described car bottom
The linear reciprocating mechanism of rigidity be connected, the direction of motion of described linear reciprocating mechanism is along the width in described compartment
Direction is arranged；The bottom at described back door is provided with the snap close mutually fastening with described latch hook or disengaging；Solid at described compartment afterbody
Surely have and the sealing joint strip of described back door phase pressing.
In the technical scheme of above-mentioned self-tipping type slag-soil truck rear door locking device, more specifically technical scheme is it may also is that institute
State linear reciprocating mechanism to include power cylinder, the lead being connected to described power cylinder one end, be fixed on described car bottom
Guide holder, described lead pass described guide holder, described latch hook is fixed on the free end of described lead.
Further, there are two and be oppositely arranged latch hook, two described latch hooks by two described leads respectively with institute
The two ends stating power cylinder are connected.
Further, described power cylinder is oil cylinder, and described oil cylinder is driven by the hydraulic power system of dumper.
Further, described snap close is the latch being fixed on support arm, and described support arm is connected to the end at described back door
End.
Further, the end of described latch hook is provided with the wedge-shaped part towards described latch.
Further, described latch hook is fixed on sleeve, and described sleeve is connected with described lead by bearing pin.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the linear reciprocating mechanism driving latch hook locking back door of rigidity is installed at car bottom, improves the strong of locking device
Degree and structural stability, improve the problem that the chain normal off of chain-type retaining mechanism splits, effectively extend service life, it is to avoid
Locking was lost efficacy, and substantially increased work efficiency.
2, rational in infrastructure, it is firm to lock, and coordinates the sealing joint strip of compartment afterbody, it is achieved the complete airtight transportation of vehicle, it is to avoid
In transportation, material leakage problem in railway carriage or compartment, improves urban health environment.

Fig. 1 is the structural representation of self-tipping type slag-soil truck rear door locking device.
Fig. 2 is the sectional view in A-A direction in Fig. 1.
Fig. 3 is the enlarged drawing in Fig. 1 at I.
Fig. 4 is the schematic diagram after back door is opened.
Detailed description of the invention
The invention will be further described for embodiment below in conjunction with the accompanying drawings:
Self-tipping type slag-soil truck rear door locking device shown in Fig. 1 to Fig. 3 mainly includes the linear reciprocating mechanism of rigidity, latch hook
1, snap close and sealing joint strip 7；Wherein, sealing joint strip 7 is fixed on compartment 12 afterbody, sealing joint strip 7 and back door 9 phase pressing；Straight line
Reciprocating mechanism is installed on bottom compartment 12, and the direction of motion of linear reciprocating mechanism is along the width in described compartment 12
Arrange；The linear reciprocating mechanism of the present embodiment includes power cylinder, lead 4 and guide holder 3, and more specifically, power cylinder is adopted
With oil cylinder 6, oil cylinder 6 is driven by the hydraulic power system 11 of dumper；Guide holder 3 is fixedly welded on platform floor longeron 10,
Lead 4 through guide holder 3 and is slidably matched with guide holder 3, and one end of lead 4 is connected with oil cylinder 6, the other end and latch hook 1
Connecting, latch hook 1 is fixed on the free end of lead 3；The lock mutually fastening with latch hook 1 or disengaging it is provided with in the bottom at back door
Button, back door 9 is hinged with top, compartment 12, it is preferred that the top at back door 9 is hinged with the bearing 14 at top, compartment 12, this reality
The snap close executing example is the latch 8 being fixed on support arm 16, and support arm 16 is connected to the bottom at back door 9, sees Fig. 3.Preferably,
Locking device has two latch hooks being oppositely arranged 1, and two latch hooks 1 pass through two leads 4 two ends respectively with oil cylinder 6 and are connected
Connect；For ease of fastening, the end at latch hook 1 is provided with the wedge-shaped part towards latch 8.It is noted that for the ease of changing
Latch hook 1, can be fixed on latch hook 1 on sleeve 1-1, and sleeve 1-1 is connected with lead 4 by the first bearing pin 2 again；Lead 4 leads to
Cross the second bearing pin 5 to be connected with oil cylinder 6.
During work, the hydraulic power system 11 of dumper carries power to oil cylinder 6, controls elongation and the contraction of oil cylinder 6, makes
The straight reciprocating motion in corresponding guide holder 3 respectively of the lead 4 at oil cylinder 6 two ends, thus band moveable lock hook 1 moves, latch hook 1
Move and control to open and locking back door 9；Latch hook 1 move toward one another at two ends, until fastening latch 8, can lock back door 9；Two ends
Latch hook 1 adverse movement disengage latch 8, locking state can be released.When back door 9 is locked, back door 9 connects with sealing joint strip 7
Touch extruding, it is therefore prevented that granule tiny in compartment 12 drops out to be trickled down on road surface.When back door 9 is in unlatching dress state, compartment 12
Body is rotated by bottom reversed pin 13 when rising, and back door 9 plate is by compartment 12 flip-top pin 15 goods in deadweight and railway carriage or compartment
Effect is lower and opens voluntarily, and in causing railway carriage or compartment, material is discharged.Compartment 12 is rotated by bottom reversed pin 13 when dropping to level, back door
9 plates are closed under the effect of deadweight voluntarily by compartment 12 flip-top pin 15, and oil cylinder 6 is carried by hydraulic power system 11
Dynamic Control latch hook 1 lock back door.
