[0021] Please refer toFigures 1-4 , a cylinder structure of an elevator buffer, comprising a cylinder body 1. A heat dissipation water tank 2 is arranged on the outer side of the cylinder barrel of the cylinder body 1. A heat exchange water tank 3 is arranged on one side of the cylinder body 1. The top on one side of the heat dissipation water tank 2 is communicated with the top of the heat exchange water tank 3 through a return pipeline 4. The bottom on one side of the heat dissipation water tank 2 is communicated with the bottom of the right side wall of the heat exchange water tank 3 through a conveying pipeline 5. An inlet 6 is opened on one side of the top of the heat exchange water tank 3. An isolation chamber 9 is installed on the inner top of the heat exchange water tank 3. A water pump 10 is installed inside the isolation chamber 9. One end of the return pipeline 4 passes through the top of the heat exchange water tank 3 and is connected to the water inlet end of the water pump 10. The water outlet end of the water pump 10 is connected to a water outlet pipeline 11. One end of the water outlet pipeline 11 passes through the right side wall of the isolation chamber 9 and is communicated with the heat exchange water tank 3. By using their mutual cooperation, the heat generated during the work of the cylinder barrel in the cylinder structure can be dissipated in time, improving the heat dissipation effect, being beneficial to long-term work, and prolonging the service life of the elevator buffer. A drain port 12 is opened on one side of the bottom of the heat exchange water tank 3, and a third valve 13 is installed on the drain port 12.
[0022] Among them, the return pipeline 4 is made of a rubber hose. By setting the return pipeline 4 as a rubber hose, the return pipeline 4 can be bent arbitrarily, which is convenient for installation.
[0023] Among them, the water outlet pipeline 11 is made of a metal pipe. Setting the water outlet pipeline 11 as a metal pipe makes it convenient for welding and sealing at the connection between the isolation chamber 9 and the water outlet pipeline 11.
[0024] Among them, the cross-sectional shape of the heat dissipation water tank 2 is a rectangular structure, so that it can be adapted to the cylinder barrel in the cylinder structure and can dissipate heat evenly around the cylinder barrel, improving the heat dissipation effect.
[0025] Among them, a first valve 8 is installed on the return pipeline 4. By setting the first valve 8, unnecessary backflow can be prevented.
[0026] Among them, a second valve 7 is installed on the conveying pipeline 5. By setting the second valve 7, when the water in the heat exchange water tank 3 is conveyed to the heat dissipation water tank 2 through the conveying pipeline 5, the second valve 7 on the conveying pipeline 5 can be opened.
[0027] The working principle and usage process of the present utility model: First, during work, the inlet 6 of the heat exchange water tank 3 is externally connected to a water source, and cooling water is injected into the heat exchange water tank 3 through the inlet 6. Then, the cooling water is conveyed to the heat dissipation water tank 2 through the conveying pipeline 5 on one side of the heat exchange water tank 3. Thus, the heat generated during the work of the cylinder barrel in the cylinder structure is dissipated in time by the cooling water in the heat dissipation water tank 2, improving the heat dissipation effect, being beneficial to long-term work, and prolonging the service life of the elevator buffer;
[0028] When the cooling water in the radiator water tank 2 is returned to the heat exchange water tank 3, the first valve 8 is opened and the second valve 7 is closed, and the water pump 10 is started to return the cooling water in the radiator water tank 2 to the heat exchange water tank 3 through the return pipeline 4 and the water outlet pipeline 11. When it is necessary to drain the water in the heat exchange water tank 3, the third valve 13 is opened to drain it from the drain port 12.
