Intelligent hydraulic buffer and buffering method

Abstract

The invention discloses an intelligent hydraulic buffer. The buffer comprises a collided head, a plunger rod arranged on the collided head, a reset spring arranged on the plunger rod in a sleeving mode, a buffer body connected with the plunger rod and a control module arranged on the buffer body. The control module comprises a shell of the control module, a power supply and / or a communication cable of the control module connected with the shell of the control module, an intelligent processing sub-module arranged on the control module, a vibration sensor arranged on the intelligent processing sub-module and a stepping motor connected with the control module. An output shaft of the stepping motor is connected with a transmission shaft on the buffer body, the vibration sensor can be integrated on the intelligent processing sub-module, and the buffer body comprises a shell and an inner cylinder barrel. The invention also provides a buffering method of the intelligent hydraulic buffer. Collision crumple guide structures are arranged on the shell, the inner cylinder barrel and the plunger rod of the buffer, the structure is simple, and the implementation cost is low.

Description

technical field [0001] The invention relates to an intelligent hydraulic buffer and a buffer method, belonging to the field of mechanical buffers. Background technique [0002] In mechanical equipment such as hoisting and transportation, elevators, port machinery, and railway vehicles, many moving parts with large masses need to be decelerated gently to prevent them from hitting other equipment or objects and causing damage. In order to achieve the purpose of energy consumption buffering, it is necessary to use energy consumption buffers, especially hydraulic buffers. [0003] The prior art has the following disadvantages: first, the existing hydraulic buffers are generally purely mechanical equipment, and their buffer performance cannot be automatically adjusted according to actual needs; second, the existing hydraulic buffer system is complex in composition and the implementation cost is relatively high; third, When the car falls rapidly and the function of the safety gea...
