Description

Energy storage buffer oil cylinder
Technical Field
The utility model relates to an energy storage buffer oil cylinder.
Background
Generally, the oil cylinders with built-in buffer structures are collectively called buffer oil cylinders, the most common buffer oil cylinder structure is shown in China patent CN211116912U, the general structure of the oil cylinders is more complex, the production cost is higher, the buffer device is arranged in the oil cylinders, the later maintenance is more loaded, the use cost is high, and the buffer oil cylinders only play a role in buffering the movement of pistons in the oil cylinders, and impact is also generated on external oil paths when the oil cylinders run, so that the existing buffer oil cylinders cannot play a role in buffering the external oil paths.
Disclosure of utility model
The utility model aims to solve the technical problem of providing the energy storage buffer oil cylinder, which can play a role in energy storage buffer by connecting the energy storage buffer oil cylinder in series with an oil way of the traditional oil cylinder, and can play a role in buffer protection on the oil way.
In order to solve the technical problems, the utility model provides an energy storage buffer oil cylinder which comprises a cylinder barrel, a cylinder bottom, a guide sleeve, a piston and a piston rod, wherein the guide sleeve and the cylinder bottom are respectively arranged at two ends of the cylinder barrel, the piston is arranged in the cylinder barrel, one end of the piston rod is matched with the piston and exceeds the piston, the other end of the piston rod passes through and exceeds the guide sleeve, a first spring is arranged between the piston and the cylinder bottom, a second spring is arranged between the piston and the guide sleeve, the first spring and the second spring are both in a compressed state, when the stress of the piston is balanced, the piston is positioned at the middle position in the length direction of the cylinder barrel, a first oil hole penetrating through the inside and the outside of the cylinder barrel is arranged at the position close to the cylinder bottom, and a second oil hole penetrating through the inside and the outside of the cylinder barrel is arranged at the position close to the guide sleeve.
For the sake of simple explanation, the energy storage buffer cylinder of the present utility model is hereinafter referred to as the buffer cylinder.
The use method and principle of the buffer oil cylinder are as follows: the buffer oil cylinder is connected in series in a hydraulic system of the working oil cylinder in a horizontal arrangement in the left-right direction, one side of the cylinder bottom is arranged on the left side, one side of the guide sleeve is arranged on the right side, when oil enters a left side cavity of the buffer oil cylinder from a first oil hole, a piston is pushed by the oil to move rightwards, at the moment, the oil in the right side cavity of the buffer oil cylinder is extruded from a second oil hole and enters a corresponding oil hole of the working oil cylinder to drive the working oil cylinder to act, meanwhile, a second spring is compressed, when the oil enters the right side cavity of the buffer oil cylinder from the second oil hole, the oil in the left side cavity is extruded and the first spring is compressed, a piston compresses the spring to generate an energy storage effect on the hydraulic system, and when the piston compresses the spring, a spring reaction force acts on the piston, and the reaction force gradually increases, so that the flow rate of the oil entering the working oil cylinder is slowed down, and the buffer effect on the working oil cylinder is achieved.
The buffer oil cylinder has the advantages that: the use of this buffer cylinder can increase buffer function to traditional hydro-cylinder that does not take buffer function to compare in the work hydro-cylinder of taking buffer design, the hydro-cylinder structure that does not take buffer is compacter, can install it in some narrow and small positions, then realize buffer function through the mode of putting this buffer cylinder cluster into hydraulic system. Compared with the traditional gap buffering, the energy storage is realized, the production cost of the oil cylinder is reduced, and the stability and the performance of the oil cylinder are improved without considering a built-in buffering mechanism.
