Description
Technical Field
The utility model relates to hook arm car field is a latch hook anti-disengaging device of hook arm car.
Background
Locking on conventional hook arm car facial make-up relies on locking hydro-cylinder to promote locking hook and hook arm or case and realize, in reality have many times to arouse because of the maloperation to break off the lock, light then crush locking hook and can not continue work, heavy then top disconnected lifting cylinder, the case that drops endangers personnel's life safety even.
Disclosure of Invention
The utility model aims at providing a latch hook anti-disengaging device of hook arm car. Is arranged on the hook arm vehicle upper-loading part and is used for preventing the locking device from unlocking.
The utility model discloses a realize like this: a hook anti-release device of a hook arm vehicle comprises two-position two-way normally-broken anti-release valve, a hook arm, a locking oil cylinder, a small auxiliary frame, a main locking hook, a vehicle beam and an auxiliary locking hook, and is characterized in that the front end of the hook arm is hinged to the front end of the small auxiliary frame, the other end of the small auxiliary frame is movably hinged to the bottom frame of the vehicle, the locking oil cylinder is installed at the front end of the small auxiliary frame, one end of the locking oil cylinder is fixed on the small auxiliary frame, and the bottom of the other end of the locking oil cylinder is positioned in a concave position of the main locking hook; the main locking hook is movably hinged at the front end of the small auxiliary frame; the two-position two-normally-off anti-unlocking valve is fixed on the side edge of the automobile cross beam, and an auxiliary locking hook is fixedly arranged on the automobile cross beam.
The main locking hook is 90 degrees.
The auxiliary locking hook is 90 degrees.
Due to the adoption of the technical scheme, the device has the characteristics of convenience, rapidness and safety in operation, simplicity in maintenance, low cost and the like.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. two-position two-way normally-off anti-unlocking valve; 2. a hook arm; 3. locking the oil cylinder; 4. a small subframe; 5. a main locking hook 6 and a car beam; 7. and an auxiliary locking hook.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1, the front end of a hook arm 2 is hinged at the front end of a small subframe 4, the other end of the small subframe 4 is movably hinged on the underframe of an automobile, a locking oil cylinder 3 is arranged at the front end of the small subframe 4, one end of the locking oil cylinder 3 is fixed on the small subframe 4, and the other end of the locking oil cylinder 3 is arranged at the bottom of a concave part of a main locking hook 5; the main locking hook 5 is movably hinged at the front end of the small auxiliary frame 4; the two-position two-normally-off anti-unlocking valve 1 is fixed on the side edge of the automobile cross beam 6, and the automobile cross beam 6 is fixedly provided with an auxiliary locking hook 7. The main locking hook 5 is at 90 degrees. The auxiliary locking hook 7 is 90 degrees.
Referring to fig. 1, this is a normal state of the hook arm vehicle: two normal-break anti-off lock valves 1 are pressed by the hook arm 2, and two normal-break anti-off lock valves 1 become normal open by normal break this moment, and the locking cylinder 3 is put through, can normally stretch out and draw back: if the locking oil cylinder 3 extends forwards to drive the main locking hook 5 to rotate forwards to lock the underframe and the small auxiliary frame 4, the hook arm 2 can rotate around the middle hole on the small auxiliary frame 4, so as to hook and place the garbage can; if the locking oil cylinder 3 retracts backwards to drive the main locking hook 5 to rotate backwards to lock the hook arm 2 to be still, the hook arm 2 can rotate around the rear overturning shaft on the small subframe 4, and therefore garbage in the garbage can is dumped.
When the hook arm vehicle is in a garbage dumping state: the hook arm 2 is lifted up, the two-position two-way normally-broken anti-falling lock valve 1 is released, the two-position two-way normally-broken anti-falling lock valve 1 is normally broken, the locking oil cylinder 3 is broken and cannot stretch out and draw back, the main locking hook 5 cannot rotate, the auxiliary locking hook 7 is separated from the main locking hook 5, and the danger that the dustbin falls down due to unlocking is avoided.
