Description
Technical field
The utility model relates to automobile technical field, particularly, relates to hydraulic switch back door, a kind of compartment.
Background technology
Applicant is that CN203739716U discloses a kind of carriage back door hydraulic lock opening device at publication number, comprise with carriage back door sidewall affixed, with the inverted L-shaped fagging of car side board top by the first hinge, be fixed at least 1 lock of carriage back door lower sidewall, be hinged at least 1 lock hook that car side board bottom corresponds to lock position, also comprise hydraulic actuating cylinder unlike the prior art, connecting rod, connecting plate, the piston rod of hydraulic actuating cylinder passes through the second hinge on the transverse slat of fagging, the cylinder body articulated linkage of hydraulic actuating cylinder, connecting rod is connected with connecting plate, one end of connecting plate and lock hook is hinged, the other end of lock hook coordinates with lock.Adopt this simple and effective technical scheme, chaufeur can control hydraulic control lever and realize the unlatching at back door with closed in operator's compartment, and starts without the need to getting off, safe ready.
Although back door is opened automatically when this structure can realize carriage lifting, but structure is comparatively complicated, and the locking at back door is realized by the pressure of latch hook, when hydraulic gear lost efficacy, certainly lead to and open by mistake in the unwitting situation of chaufeur, can make vehicle in the process of moving the shedding of goods, reveal, cause economic loss and environmental pollution; Serious words also can cause the damage of vehicle and the injures and deaths of personnel.
Summary of the invention
The purpose of this utility model is based on the deficiencies in the prior art, provide a kind of be not only applicable to after turn over formula self-discharging carriage, the one that also can be applicable to common non-post dumping wagon and conveyor type self-discharging carriage is safe and reliable, hydraulic switch back door, structure simple compartment.
In order to solve the problem, the technical solution used in the present invention is:
This hydraulic switch back door, a kind of compartment, comprise the fagging 3 affixed with carriage back door 1 sidewall, the upper double acting hydraulic cylinder 7 that cylinder body is hinged on car side board 2, piston rod is hinged on fagging 3 transverse slat, unlike the prior art: fagging 3 arranges the first slotted hole 13, first bearing pin 5 away from the transverse slat side of carriage back door and is fixed on car side board 2 through the first slotted hole 13; Carriage back door 1 lower sidewall sets firmly lock hook 4, and correspond to lock hook 4 aperture position in car side board 2 bottom and set firmly lock 6, lock hook 4 coordinates with lock 6.Adopt this simple and effective technical scheme, chaufeur can control hydraulic control lever and realize the unlatching at back door with closed in operator's compartment, and starts without the need to getting off, safe ready; Back door can hover over a certain position after opening simultaneously, and rocking of compartment can not make back door and goods and car side board collide, long service life; Thoroughly locked after back door is closed, can not fit badly or unexpected situation generation of opening.
For the ease of the adjustment of lock hook 4 with lock 6 cooperation position, lock hook 4 is arranged the second slotted hole 8, carriage back door 1 sets firmly bolt, bolt is through the bottom by nut 9, lock hook 4 being fixed on carriage back door 1 sidewall after slotted hole 8.Adopt this technical scheme, situation can be coordinated at any time by two nuts adjustment lock hooks and lock, be conducive to this device long-time use and without the need to specialized maintenance.
As further preferred version, when the distance of definition first bearing pin 5 to carriage back door 1 outer rim is L, the distance of the first bearing pin 5 to the second bearing pin 10 is Lx, then 1/2L≤Lx≤2/3L.This technical scheme, reduces the application force dug needed for back door, and the diameter of hydraulic cylinder piston can suitably reduce, and is conducive to cost-saving; Reduce the stroke of the piston dug needed for back door, the correspondingly corresponding reduction of the rigidity requirement of piston rod, be also conducive to cost-saving simultaneously.

Detailed description of the invention
Embodiment 1, see Fig. 1-3.
A kind of hydraulic switch back door, compartment, comprise the fagging 3 affixed with carriage back door 1 sidewall, the upper double acting hydraulic cylinder 7 that cylinder body is hinged on car side board 2, piston rod is hinged on fagging 3 transverse slat, fagging 3 arranges the first slotted hole 13, first bearing pin 5 away from the transverse slat side of carriage back door and is fixed on car side board 2 through the first slotted hole 13; Carriage back door 1 lower sidewall sets firmly lock hook 4, and correspond to lock hook 4 aperture position in car side board 2 bottom and set firmly lock 6, lock hook 4 coordinates with lock 6.The distance of the first bearing pin 5 to carriage back door 1 outer rim is L=420mm, and the distance of the first bearing pin 5 to the second bearing pin 10 is Lx=230mm.
Assuming that the carriage back door of initial condition is closed, see Fig. 1, lock 4, in the lateral direction completely can not displacement completely in the opening of lock hook 6.
The hydraulic control lever controlling back door when chaufeur in operator's compartment makes the first liquid mouth 71 feed liquor of hydraulic actuating cylinder 7, second liquid mouth 72 fluid, piston rod is protruding generation thrust gradually, because the first bearing pin 5 is through in the first slotted hole 13, first this thrust make the carriage back door 1 entirety upwards lifting affixed with fagging 3, the result of lifting makes lock 4 leave in the opening of lock hook 6 gradually, see Fig. 2.When the first bearing pin 5 arrives at the lower end of the first slotted hole 13, carriage back door 1 entirety is upwards lifted and can not be lifted, along with piston rod continues protruding generation thrust, carriage back door 1 entirety can only around the first bearing pin 5 clickwise, thus carriage back door 1 is opened gradually, until fully open, see Fig. 3.
The hydraulic control lever controlling back door when chaufeur in operator's compartment makes the first liquid mouth 71 fluid of hydraulic actuating cylinder 7, second liquid mouth 72 feed liquor, piston rod is inwardly retracted gradually, under the pulling force of piston rod and the double action of carriage back door self gravitation, carriage back door overturns downwards around the first bearing pin 5 conter clockwise, laminating car side board 2 gradually, now lock 4 is gradually near the opening of lock hook 6, piston rod along with hydraulic actuating cylinder 7 continues inwardly to retract, pull carriage back door to bottom offset, lock 4 enters in the opening of lock hook 6 completely, in the lateral direction completely can not displacement, back door is thoroughly locked.Can not fit badly or unexpected situation generation of opening.
Embodiment 2, see Fig. 1-3.
Other are with embodiment 1, unlike lock hook 4 being arranged the second slotted hole 8, carriage back door 1 set firmly bolt, and bolt is through the bottom by nut 9, lock hook 4 being fixed on carriage back door 1 sidewall after slotted hole 8.Adopt this technical scheme, situation can be coordinated at any time by two nuts adjustment lock hooks and lock, be conducive to this device long-time use and without the need to specialized maintenance.
