Description
Technical field: the utility model relates to a kind of automobile driving cabin overturning, Locking Device, particularly a kind of cab-over-engine truck driver's cab turnover, Locking Device.
Background technology: motor car engine is the heart of self-propelled vehicle, and is most important to its maintenance, repairing.The operator's compartment of domestic cab-over-engine truck is to be fixed on the chassis basically before this, and most of producers adopt the method for opening square hole on the operator's compartment base plate, with maintenance, the repairing that makes things convenient for driving engine.Yet, because engine maintenance, repairing work itself are just extremely heavy and not easy to operate, therefore, in its limited spatial dimension, safeguard, repair still very inconvenience, carry out sometimes even at the bottom of being forced to pierce car, both be difficult to operate, and dangerous; Sometimes in order to strive for bigger service clearance, have no alternative and headstock have to be unloaded, both time-consuming, need certain special tool and equipment again.
Summary of the invention: technical problem to be solved in the utility model is: is intended to overcome the deficiency of above-mentioned prior art, a kind of automobile driving cabin overturning, Locking Device is provided, and when needs keep in repair driving engine, 1, operator's compartment can be dug easily; 2, turn over when rising to certain angle when operator's compartment, strut mechanism can open automatically and prop up operator's compartment, and automatic self-locking, makes the operator's compartment of being propped up have enough spaces, with convenient for maintaining personnel's maintenance and repair; 3, after maintenance and repair finish, press the lower supporting rod self-locking device, operator's compartment will utilize self gravitation to fall, and lockable mechanism adopts retrocession safely operator's compartment to be locked on the vehicle frame.Because whole operator's compartment is mounted on four strong points of whole upset, lockable mechanism, consider that from taking advantage of the traveling comfort of driving driver's cab turnover, lockable mechanism also must have buffering, cushioning effect simultaneously.
Its technical scheme: a kind of automobile driving cabin overturning, Locking Device is characterized in that:
Turning device is made up of strut mechanism and switching mechanism; Strut mechanism forms by upper and lower strut bar is hinged, and the upper end of upper support bar respectively is connected a support that is fixed on operator's compartment base plate and the chassis by bearing pin respectively with the lower end of lower support bar; Switching mechanism is made of central siphon assembly, torsion bar, central siphon, left and right support, supporting arm and torsion bar arm assembly, torsion bar is connected by the spline assembling with central siphon, be installed in the affixed left and right support in chassis on, near supporting arm being housed on the central siphon of left and right support inboard respectively, right support outside torsion bar arm assembles with torsion bar enforcement spline by central siphon and is connected; Locking Device is made up of left and right support, bearing support, locking bail assembly and long and short pull bar and steering unit;
The locking bail assembly is made of lock bracket, big latch hook, connecting arm and torsion spring, rivets with lock bracket after the hinged back of latch hook and connecting arm is assembled together with torsion spring greatly; Left and right locking bail by the mounting hole symmetry of lock bracket be installed in wall behind the operator's compartment on one's body the big latch hook of left and right locking bail match with lock ring on the left and right support respectively; Left and right support is separately fixed on the left and right bearing support, and left and right bearing support is separately fixed on the chassis; Left and right locking bail assembly is hinged by the bearing pin and the long draw of connecting arm respectively; Steering unit constitutes by paying latch hook, big handgrip, safe latch hook, fixed support and torsion spring, and pair latch hook, big handgrip, safe latch hook are hinged on the fixed support by bearing pin and torsion spring respectively; Short rod end in control mechanism assembly is hinged with big handgrip, and the bearing pin of connecting arm is hinged in the other end and the left locking bail, and steering unit is fixed on behind the operator's compartment on the left of the wall by the mounting hole on the fixed support.
Its technique effect is: when needing repairing 1) manipulating handgrip on the pulling Locking Device, utilize four connecting rod principles, by long and short pull bar, make big latch hook on the left and right locking bail respectively with the chassis attaching parts---the rack pin shaft on the after poppet assembly breaks away from; 2) the safe latch hook in the pulling control mechanism assembly makes safe latch hook and chassis attaching parts---and the rack pin shaft on the supporting bracket of back breaks away from; 3) under the effect of torsion bar elevate a turnable ladder power, operator's compartment is dug around centre of gration, drives the strut mechanism opening and props up and automatic self-locking, and the operator's compartment that is connected on the trip shaft pipe assembly supporting arm is propped up in predetermined angle, thereby realize the purpose that operator's compartment is dug, expanded the space of engine maintenance.
Keep in repair the back 1 that finishes) press the self-locking hammerlock in the lower supporting rod mechanism, utilize the gravity of operator's compartment self, operator's compartment is fallen; 2) be connected safe latch hook auto lock on the operator's compartment and be installed in lock ring on the back supporting bracket on the chassis; 3) promote manipulating handgrip on the Locking Device, by long and short pull bar interlock make in the left and right locking bail big latch hook respectively with after poppet on lock pin locking, connecting arm turns over automatic self-locking behind the latching point; 4) pay latch hook locking steering unit lock pin after, automatic self-locking, thus the operator's compartment that falls is linked together with vehicle frame safely and reliably.
