Abstract
A hydraulic lock mechanism for the driver's cab of car is composed of hydraulic cylinder, lock block fixed to one side of the recess of lock body, spring, lock body with a recess for holding said lock pin, and a lock pin with a locking recess for locking said lock pin to the bottom of said recess. The utility model discloses only need through a locking piece, can realize opening and closing two kinds of states of lock, simplify traditional hydraulic pressure lock structure, make its performance more reliable, the cost is more cheap.
Description
Technical field
The utility model relates to a kind of hydraulic lock of automobile cab, relates in particular to a kind of turning automobile cab hydraulic lock mechanism.
Background technology
At present, the hydraulic lock of the turning operator's compartment of commercial vehicle/comm..vehicle adopts the mechanical interlocking structure mostly, its complex structure, and cost is higher.Be called " automobile cab hydraulic lock " as name, the patent No. is that 200320107156.7 Chinese patent is exactly so, and this patent adopts the version of auxiliary lock dog, by unlatching and the lockup state of auxiliary lock dog at different position control lock dogs.
The problem of this patent existence is, must could realize the control to lock dog unlatching and lockup state indirectly by the control to auxiliary lock dog position, structure complicated, and number of parts is many, and efficient is lower, the cost height.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple in structurely, and number of parts is few, and cost is low, the automobile cab hydraulic lock mechanism that performance is good.
For achieving the above object, the utility model adopts following technical scheme: automobile cab hydraulic lock mechanism, comprise hydraulic ram, lock dog, spring, lock body and lock pin, it is characterized in that being provided with in the described lock body groove that can insert lock pin, described hydraulic ram is fixed on a side of lock body groove, described lock dog middle part is hinged on the pivot shaft between lock body groove and the hydraulic ram, lock dog one end contacts with the piston rod upper surface of hydraulic ram, the other end is corresponding with lock pin and be provided with an energy lock pin is locked in the locking groove of lock body bottom portion of groove, is equipped with can force lock dog to pivot and make the one end be pressed on the spring of the piston rod upper surface of hydraulic ram on above-mentioned pivot shaft.
In lock dog, with the locking groove of the cooresponding end of lock pin be circular groove, its diameter is greater than the lock pin diameter.
In lock dog, the outside face of an end that contacts with the piston rod upper surface of hydraulic ram is a cambered surface.
Described lock dog is L shaped lever, and its corner, middle part is hinged on the pivot shaft,
Groove in the described lock body is a U-lag.
When with the cooresponding end lock dog of lock pin in locking groove when lock pin is locked in the lock body bottom portion of groove, there is the gap in locking groove in lock pin and the lock dog along pivot shaft and lock pin center line connecting direction, and this gap can guarantee that the locking groove in the lock dog is not subjected to the restriction of lock pin and rotates to the position of leaving lock pin and lock body groove.
One end and the oil cylinder of the utility model lock dog are kept in touch, and transmission power, i.e. force transfer end.The other end of lock dog is relative with lock pin, and locking groove and lock pin above it are identical substantially, are used for playing spacing effect, i.e. positive stop end.When the positive stop end of lock dog was above lock pin, the locking groove on it formed one near the osed top circular groove with the groove of lock body, and lock pin is enclosed in the groove.The lock pin diameter is slightly littler than this circular groove.Locking groove and lock pin coincide substantially and can make it stressed even when spacing, stress concentration can not occur.
Because the lock pin diameter is slightly littler than the locking groove, when lock pin under coupled operator's compartment action of gravity, when falling within the bottom of groove of lock body, lock pin will and the locking groove of lock dog between keep certain clearance along pivot shaft and lock pin center line connecting direction.Because the reservation of this gap, the positive stop end of lock pin can not be subjected to the restriction of lock pin and be rotated clockwise to the left side, thereby reserve the space that lock pin moves vertically upward fully, realize the opening of lock.
Same because the reservation of this gap, the positive stop end of lock dog also can not be subjected to the restriction of lock pin and left-hand revolution to the top of lock pin, realize the closed condition of locking.
The utility model only need pass through a lock dog, can realize the opening and closing two states locked, simplifies the conventional hydraulic lock construction, makes its performance more reliable, and cost is more cheap.
Description of drawings
Fig. 1 is a lock closed condition scheme drawing of the present utility model;
Fig. 2 is a lock opening scheme drawing of the present utility model.
Among the figure, 1-oil cylinder, 2-lock dog, 3-spring, 4-lock body, 5-lock pin, 6-pivot shaft.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
The utility model comprises small-sized hydraulic oil cylinder 1, lock dog 2 and spring 3 thereof, lock body 4 and lock pin 5.Be provided with the U-shaped groove that can insert lock pin 5 in the lock body 4, lock body 4 adopts the punching press steel plate to make.Hydraulic ram 1 is fixed on the left side of U-shaped groove in the lock body 4.Lock dog 2 is L shaped lever, is formed by the riveted joint of multi-disc punching press steel plate, and its corner, middle part is hinged on the pivot shaft 6 between lock body U-shaped groove and the hydraulic ram 1, is fixed with on pivot shaft 6 and forces the spring 3 of lock dog 2 around its left-hand revolution.In lock dog 2, with the circular groove that is provided with of lock pin 5 cooresponding ends, its diameter is greater than lock pin 5 diameters; The outside face of an end that contacts with the piston rod upper surface of hydraulic ram 1 is set to cambered surface.
When with the cooresponding end lock dog of lock pin in locking groove when lock pin is locked in the lock body bottom portion of groove, there is the gap in locking groove in lock pin and the lock dog along pivot shaft and lock pin center line connecting direction, and this gap can guarantee that the locking groove in the lock dog is not subjected to the restriction of lock pin and rotates to the position of leaving lock pin and lock body groove.
Under the operator's compartment horizontality, hydraulic ram 1 does not have oil pressure, and lock dog 2 is under the effect of spring, and its force transfer end is pressed onto the piston of hydraulic ram 1 and hydraulic ram 1 flush position, and the positive stop end of lock dog 2 is positioned at lock pin 5 tops.When running car, can be fine play protection lock pin 5 and can not break away from lock dog 2, thereby guaranteed the steady safety of operator's compartment.
Hydraulic oil in the elevating ram that hydraulic ram 1 of the present utility model and upset operator's compartment are used is homology hydraulic oil.When the operator's compartment lifting, oil pressure in the elevating ram that oil pressure in the hydraulic ram 1 and upset operator's compartment are used rises simultaneously, the piston rod of hydraulic ram 1 ejects under the oil pressure effect, and overcomes the application force of the spring 3 of lock dog 2, makes lock dog 2 around pivot shaft 6 clickwises.When the positive stop end of lock dog 2 moved to the left side by preset clearance, opened fully in the space of lock pin 5 tops, and promptly hydraulic lock mechanism is in open mode.At this moment, operator's compartment upwards lifts under the hoisting force effect.
When operator's compartment fell after rise, oil pressure reduced, and the piston rod of hydraulic ram 1 is pushed back under the application force of the spring 3 of lock dog 2, simultaneously lock dog 2 left-hand revolutions.When the positive stop end of lock dog 2 moved to lock pin 5 tops by preset clearance, the superjacent air space of lock pin 5 was closed, and promptly the hydraulic lock assembly is in closed condition.
