Example Embodiment

[0011] like figure 1 As shown in the figure, the hydraulic anti-rotation self-unlocking device includes an anti-rotation self-unlocking hydraulic cylinder 1 and a rotary locking surface 2 respectively arranged on two parts that are rotatably matched with each other. The anti-rotation self-unlocking hydraulic cylinder 1 includes a cylinder block 11, Cylinder rod 12 and piston 13, cylinder rod 12 and cylinder rod hole 15 on the front end cover 14 of cylinder block 11 are axially sliding and sealingly matched, piston 13 is slidably installed in cylinder block 11 and fixedly installed at the rear end of cylinder rod 12, The front end of the cylinder rod 12 located outside the cylinder body 11 is provided with a friction locking block 16 which is matched with the rotary locking surface 2 . The cylinder body 11 is provided with a number of butterfly springs located between the piston 13 and the rear end cover 17 of the cylinder body 11 . 18. The side wall of the cylinder block 11 is...

Abstract

The invention relates to a hydraulic anti-rotation self-unlocking device which comprises an anti-rotation self-unlocking hydraulic cylinder (1) and a rotary locking face (2), when the anti-rotation self-unlocking hydraulic cylinder (1) is not subjected to hydraulic pressure, a friction locking block (16) is tightly pressed on the rotary locking face (2) to achieve the anti-rotation locking effect, and when the anti-rotation self-unlocking hydraulic cylinder (1) is subjected to hydraulic pressure, the friction locking block (16) is tightly pressed on the rotary locking face (2) to achieve the anti-rotation locking effect. And the friction locking block (16) does not tightly press the rotary locking surface (2) any more to automatically release the locking effect. A hydraulic anti-rotation self-unlocking device is arranged on a crane (6) of the hoisting transport vehicle, an anti-rotation self-unlocking hydraulic cylinder (1) is installed on a base (61), and a friction locking block (16) is matched with a rotating face on a hoisting rotating seat (62). Mechanical devices which are in running fit with each other are automatically locked and unlocked in a hydraulic mode, a locking pin rod does not need to be manually inserted and pulled to prevent rotation between parts and unlock, and the hydraulic locking device is convenient and safe to use.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a hydraulic anti-rotation self-unlocking device and a hoisting and transporting vehicle using the device. Background technique [0002] Many mechanical devices have mechanical parts that rotate together during operation and need to be locked together when not in operation. Taking a crane as an example, when no hoisting operation is required, its hoisting assembly needs to be firmly locked on the hoisting base to prevent rotation for transportation and safety needs. At present, the device used to prevent rotation on these devices is generally a locking pin rod disposed between two rotating and mating components. The locking pin rod is pulled out when the rotation matching is required, and the locking pin rod is inserted when the rotation matching is not required. The pulling and inserting of the locking pin rod is generally done manually. If the staff forgets to insert or unplug the locking...
