Abstract
Disclosed is a hydraulic lock which belongs to the motor vehicle part field. The utility model provides a hydraulic lock which is safe and flexible and is used for locking and unlocking the driving cab through hydraulic power. The utility model comprises an oil cylinder fixing mount, a locking plate, a fixing pin, a lock hook and a large tension spring; the oil cylinder subassembly is mounted on the oil cylinder fixing mount; the top part of a hydraulic push rod is supported on the locking plate; one end of a small tension spring is mounted on the oil cylinder fixing mount, and the other end is mounted on the locking plate. The hydraulic lock has simple structure, flexible opening, has no oil leakage and is safe and reliable.
Description
Technical field:
The utility model belongs to the self-propelled vehicle part field.
Background technology:
Along with the development of heavy motor vehicle and the raising of China's living standards of the people, navigating mate requires to improve gradually to the traveling comfort of operator's compartment, main embodiment operator's compartment in motion has the suspension vibration-damping function, need equipped hydraulic cab-tilting mechanism on the structure, and needing corresponding lockset, these functions fix, make operator's compartment be in locking state in the process of moving, operator's compartment is freely overturn as long as open lockset during maintenance.And the structure of existing employed lockset exists unlatching dumb, the more high shortcoming of oil leakage fault rate.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of reaching by hydraulic power that operator's compartment is opened with locked, and safe hydraulic lock flexibly.
The utility model comprises oil cylinder fixed mount, jam plate, set pin, latch hook, the big extension spring that is installed on the adapter plate, the oil cylinder branch unit is installed on the oil cylinder fixed mount, the end of hydraulic push rod withstands on the jam plate, and small extension spring one end is installed on the oil cylinder fixed mount, and the other end is installed on the jam plate.
The utility model is simple in structure, and it is oil tight flexibly, safe, reliable to have a unlatching:
1, opens the flexible oil tight life-span more than 50,000 times.
When 2, reliable hydraulic lock was locked, latch hook was deviate from power greater than 3800Kg, vertically holding capacity 1500Kg.
3, locked reliable by oil cylinder external fixation extension spring return, avoid catching phenomenon.
Description of drawings:
Fig. 1 is the utility model structure locking state scheme drawing;
Fig. 2 is the utility model inner structure open mode scheme drawing;
Fig. 3 is that the utility model Fig. 2 A-A is to scheme drawing.
The specific embodiment:
The utility model comprises oil cylinder fixed mount 1, jam plate 4, set pin 7, latch hook 8, the big extension spring 9 that is installed on the adapter plate 6, oil cylinder branch unit 2 is installed on the oil cylinder fixed mount 1, the end of hydraulic push rod 3 withstands on the jam plate 4, small extension spring 5 one ends are installed on the oil cylinder fixed mount 1, and the other end is installed on the jam plate 4.
Its principle of work is:
During open mode, pressure oil promotes hydraulic push rod 3, and hydraulic push rod 3 withstands on the jam plate 4 and jam plate 4 is rotated and steps down, and latch hook 8 is opened under the effect of big extension spring power automatically, thereby realizes open mode;
During locking state, the operator's compartment axle falls latch hook is pushed back locking position from open position, and jam plate 4 is locked with latch hook under the effect of small extension spring 5 power.
