[0001] The utility model relates to the technical field of hydraulic cylinders for metallurgical equipment, in particular to a heavy metallurgical equipment hydraulic cylinder with a buffer structure. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application occasion, and other devices are indispensable. The existing patent is a new type of heavy metallurgical equipment hydraulic cylinder, and the patent publication number CN217107658U includes a hydraulic cylinder body, a protective frame is provided on the outside of the hydraulic cylinder body, and multiple groups of auxiliary mechanisms are provided inside the protective frame, and the auxiliary mechanism includes a first connecting block. The new heavy-duty metallurgical equipment hydraulic cylinder can perform the first layer of force unloading for external forces through the design of the buffer pad to reduce the violent internal vibration, and through the design of the auxiliary mechanism, when the hydraulic cylinder body is subjected to external collision, the first connecting block can be driven to move, the movement of the first connecting block drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the second connecting block. At this time, the spring is compressed, and at the same time, the auxiliary mechanism on the other side has the opposite working principle, thereby achieving the effect of reducing the force of the hydraulic cylinder body inside the protective frame. The utility model has the advantages of good buffering and protection effect, simple structure and wide application range.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although it can be driven by the connecting plate when in use, due to the lack of an effective buffering and anti-vibration structure, when the hydraulic cylinder is outputting power, if the equipment falls due to loose fixation and other reasons, causing impact on the hydraulic cylinder, it will cause damage to the hydraulic cylinder. Therefore, we propose a heavy-duty metallurgical equipment hydraulic cylinder with a buffering structure to solve the above-mentioned problems. Utility Model Content
