Further, described latch hook is fixed on sleeve, and described sleeve is connected with described lead by bearing pin.
Due to employing technique scheme, the utility model compared with prior art has the advantages that：
1st, the linear reciprocating mechanism installing rigidity in car bottom drives latch hook locking back door, improves locking device
Intensity and structural stability, improve the problem that the chain normal off of chain-type retaining mechanism splits, effectively extend service life,
Avoid locking to lose efficacy, and substantially increase operating efficiency.
2nd, rational in infrastructure, locking is firm, the sealing joint strip of cooperation compartment afterbody, realizes the complete airtight transportation of vehicle, it is to avoid
Material leakage problem in railway carriage or compartment in transportation, improves urban health environment.
Brief description
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 at I in Fig. 1.
Fig. 4 is the schematic diagram after back door is opened.
Specific embodiment
The utility model is described in further detail 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 include rigid linear reciprocating mechanism,
Latch hook 1, lock and sealing joint strip 7；Wherein, sealing joint strip 7 is fixed on compartment 12 afterbody, and sealing joint strip 7 is mutually pressed with back door 9；
Linear reciprocating mechanism is installed on compartment 12 bottom, and the direction of motion of linear reciprocating mechanism is along the width in described compartment 12
Direction is arranged；The linear reciprocating mechanism of the present embodiment includes power cylinder, lead 4 and guide holder 3, more specifically, power
Cylinder adopts oil cylinder 6, and oil cylinder 6 is driven by the hydraulic power system 11 of dumper；Guide holder 3 is fixedly welded on platform floor longeron 10
On, lead 4 passes through guide holder 3 being slidably matched with guide holder 3, and one end of lead 4 is connected with oil cylinder 6, the other end and lock
Hook 1 connects, and latch hook 1 is fixed on the free end of lead 3；It is provided with the bottom at back door and mutually fasten with latch hook 1 or disengage
Lock, back door 9 is hinged with compartment 12 top it is preferred that the top at back door 9 is hinged with the bearing 14 at compartment 12 top, this
The lock of embodiment is the latch 8 being fixed on support arm 16, and support arm 16 is connected to the bottom at back door 9, referring to Fig. 3.Preferably
, locking device has two latch hooks being oppositely arranged 1, and two latch hooks 1 pass through two lead 4 two ends with oil cylinder 6 respectively
It is connected；For ease of fastening, the end of latch hook 1 is provided with the wedge-shaped part towards latch 8.It is noted that for the ease of
Change latch hook 1, latch hook 1 can be fixed on sleeve 1-1, sleeve 1-1 is connected with lead 4 by the first bearing pin 2 again；Lead
