The utility model has the advantages of simple structure, reliable connection, flexible regulation and enhanced security of riding environments, which can give consideration to practical and economic requirements and fully satisfies the requirements of users. The new wave of a new generation of cab suspension of heavy duty vehicles can be led.
Description
(1) technical field
The utility model relates to a kind of operator's compartment hydraulic lock locking apparatus, particularly a kind of hydraulic lock locking apparatus of heavy goods vehicles full-floating Cab mounting.
(2) background technology
Existing operator's compartment hydraulic lock locking apparatus adopts the pressing plate lock usually; because its device is exposed to automobile rear; the back easy-to-rust exposes to the sun and rain; operate insensitively, do not open, occur throwing off phenomenon when jolting appears in automobile easily through regular meeting; dangerous hidden danger; and its structure more complicated, volume is big, and is relatively heavier.
(3) summary of the invention
The technical problems to be solved in the utility model is: a kind of flexible and convenient operation, safe and reliable, operator's compartment hydraulic lock locking apparatus that volume is little are provided.
In order to solve the problems of the technologies described above, the utility model comprises locking signal switch plate, hydraulic ram, hydraulic ram push rod and lock dog; Hydraulic ram push rod and lock dog are hinged on respectively on the support guide plate, lock pin is in the top of lock dog, locking signal switch plate is hinged on the adapter plate, the head of the push rod of hydraulic ram contacts with the hydraulic ram push rod, locking signal switch plate and hydraulic ram push rod intersect, lock dog by energy of rotation withstand on locking signal switch plate below; Locking signal switch plate, hydraulic ram push rod and lock dog all have a pull back spring.
For return is rapid, the pull back spring of hydraulic ram push rod and lock dog all is fixed on its hinged place.
The utility model is simple in structure, connects reliably, regulates flexibly, has strengthened the driving environmentAL safety; Take into account needs practical and economic two aspects, fully adapted to user's requirement, have vast market prospect, lead the new trend of heavy goods vehicles Cab mounting of new generation.

Fig. 2 is a blocking scheme drawing of the present utility model.
Wherein, 1. locking signal switch plate, 2. rivet, 3. adapter plate, 4. sleeve, 5. pull back spring, 6. rivet, 7. hydraulic ram, 8. pull back spring, 9. hydraulic ram push rod, 10. support guide plate, 11. pull back springs, 12. rivet, 13. rivets, 14. lock dogs, 15. limiting stoppers, 16. lock pins.
(5) specific embodiment
A kind of specific embodiment as shown in Figure 1 and Figure 2 comprises locking signal switch plate 1, hydraulic ram 7, hydraulic ram push rod 9, lock dog 14 and lock pin 16; Hydraulic ram push rod 9 and lock dog 14 are hinged on a side of support guide plate 10 respectively, spacing limiting stopper 15 and a spacing rivet 13 to lock dog 14 is arranged on support guide plate 10, locking signal switch plate 1 is hinged on the adapter plate 3, an energy is arranged to its spacing rivet 2 on the adapter plate 3 in locking signal switch plate 1 left side, lock pin 16 1 ends are connected on the adapter plate 3, the other end is pressed on the lock dog 14, hydraulic ram 7 is positioned at the lower left of this device, the head of the push rod of hydraulic ram 7 contacts with the lower end of hydraulic ram push rod 9, intersect the lower end of locking signal switch plate 1 and the upper end of hydraulic ram push rod 9, lock dog 14 after its hinge-point rotates to an angle, can withstand on locking signal switch plate 1 below, make lock dog 14 lockings.Locking signal switch plate 1, hydraulic ram push rod 9 and lock dog 14 all have a pull back spring (5,8,11), the pull back spring of hydraulic ram push rod 9 and lock dog 14 (8,11) all is fixed on its hinged place, pull back spring 11 1 ends are fixed on the support guide plate 10 by rivet 12, the other end is stuck on the lock dog 14, one end of pull back spring 8 is pressed on the support on the hydraulic ram 7, the other end hangs on the locking signal switch plate 1, pull back spring 5 is fixed on the adapter plate 3 by rivet 6, the one end withstands on adapter plate 3 upper bushes 4, and the other end withstands on the locking signal switch plate 1.
The principle of work of this specific embodiment: operator's compartment presses down lock pin 16 when falling after rise, lock pin 16 promotes lock dog 14 left-hand revolutions, rotate to when contacting with locking signal switch plate 1, promote lock signal key-board 1 clickwise, when lock dog 14 forwarded the below of locking signal switch plate 1 to, locking signal switch plate 1 was with lock dog 14 lockings (as shown in Figure 2).When needs are unblanked, open the hydraulic oil of hydraulic ram 7, the push rod of hydraulic ram 7 promotes hydraulic ram push rod 9 under the effect of hydraulic oil, make its left-hand revolution, hydraulic ram push rod 9 drives locking signal switch plate 1 clickwise, and when locking signal switch plate 1 whiz lock dog 14, lock dog 14 is return under the effect of pull back spring 11, oil cylinder quits work, and locking signal switch plate 1 and hydraulic ram push rod 9 be return (as shown in Figure 1) under the effect of its pull back spring.
