Abstract
The utility model relates to a hydraulic locking device, which mainly comprises a cylinder barrel, a locking piston, a conical pressing ring, a pressing sleeve assembly, a cylinder cover, a flange cover, a disc spring and the like, wherein the pressing sleeve assembly is in conical surface contact with the conical pressing ring and the conical pressing ring is sheathed on the piston rod of a main oil cylinder. When the piston rod of the main oil cylinder moves to any position, the conical pressing ring can lock the piston rod of the main oil cylinder. When the piston rod of the main oil cylinder is required to move, pressure oil is fed into a chamber a, the disc spring is compressed, the conical pressing ring is released and the piston rod of the main oil cylinder can move freely.
Description
Technical field:
The utility model relates to a kind of locking device, relates in particular to a kind of hydraulic lock device.
Background technique:
Some oil hydraulic cylinder needs some device that the piston rod of oil hydraulic cylinder is pinned when stop motion.To prevent that the external force effect from causing piston and piston rod to move and causing accident.
Summary of the invention:
The piston rod movement that the purpose of this utility model provides a kind of master cylinder is during to any position, and the taper pressure ring can both be locked the oil hydraulic cylinder locking device of main oil cylinder piston bar.
The technical solution of the utility model is achieved in that a kind of hydraulic lock device, and it comprises cylinder barrel, latching ram, taper pressure ring, gland assembly, cylinder cap, blind flange, dish spring.The gland assembly is that the conical surface contacts with the taper pressure ring, and the taper pressure ring is enclosed within on the piston rod of master cylinder, and cylinder cap is connected by screw with blind flange.
The utility model has the advantages that: adopt disc spring pressing gland assembly can lock the main oil cylinder piston bar at an arbitrary position.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Embodiment:
A kind of hydraulic locking cylinder device, it mainly is made of main parts size such as cylinder barrel 1, latching ram 2, taper pressure ring 3, gland assembly 4, cylinder cap 5, blind flange 6, dish springs 7.Gland assembly 4 is that the conical surface contacts with taper pressure ring 3, and taper pressure ring 3 is enclosed within on the piston rod of master cylinder, and cylinder cap 5 and blind flange 6 are connected by screw.The piston rod movement of its master cylinder is during to any position, and taper pressure ring 3 can be locked main oil cylinder piston.When piston rod need move, make a chamber 8 logical pressure oils.The compression of dish spring, the taper pressure ring unclamps.At K, M the working condition that can show the hydraulic lock device near switch at any time is installed simultaneously.
