Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a fast-cooling hydraulic cylinder. 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 using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] A Chinese patent discloses a hydraulic oil cylinder that can quickly cool down (authorization announcement number CN217481675U). The patented technology includes an empty box, the left end of the inner middle upper part of the empty box is fixedly connected to the rear end of the cylinder body of the hydraulic rod body, and the front end of the cylinder body of the hydraulic rod body is fixedly connected to the middle upper part of the inner right end of the empty box. In the utility model, the water pump is used to pump water through the hose and then returns to the empty box through the connecting pipe. The hose is wrapped around the outer side of the cylinder body of the hydraulic rod body, so that the heat energy generated by the hydraulic rod body is absorbed and dissipated, and the temperature is effectively reduced. The ice ball cools the water in the empty box, which is convenient for the water pump to circulate and pump water for cooling, thereby increasing the service life of the hydraulic rod body. In addition, the water pump pumps water through the hose for cooling, so that the cooling structure of the hydraulic rod body is simple and effective. When not in use, the water is discharged through the drain pipe to reduce the weight of the empty box. It is convenient to carry with the handrail and is more convenient to use.

[0004] However, there are still some shortcomings in this patent. When the patent is used, due to the thick wall thickness of the cylinder and the poor heat conduction of the cylinder material, the water flow can only take away the temperature of the outer wall of the cylinder, but cannot quickly take away the heat inside the cylinder, resulting in the temperature inside the cylinder still being high, the cooling effect is poor, and it is not convenient to use. Therefore, those skilled in the art provide a fast cooling hydraulic cylinder to solve the problems raised in the above background technology. Utility Model Content

[0041] Example 1

[0042] See also Figure 1-3 As shown, this embodiment is a fast cooling hydraulic cylinder, comprising:

[0043] Hydraulic cylinder assembly 100; The hydraulic cylinder assembly 100 includes a cylinder barrel 110;

[0044] The cooling assembly 200 includes a sleeve 210 placed on the outer surface of the cylinder 110, a first plug 220 connected to the bottom of the sleeve 210, a second plug 230 connected to the top of the first plug 220, an air inlet pipe 240 connected to the outer side of the lower end of the sleeve 210, an air outlet pipe 250 connected to the outer side of the upper end of the sleeve 210, and through holes 260 opened around the upper end of the cylinder 110.

[0045] The hydraulic cylinder assembly 100 further includes a piston rod 120 connected to an internal position of the cylinder barrel 110;

[0046] The diameter of the first plug 220 is smaller than that of the second plug 230, and the central axis of the first plug 220 and the central axis of the second plug 230 are collinear;

[0047] The first plug 220 and the second plug 230 are located inside the through hole 260, and the diameter of the second plug 230 is the same as the diameter of the through hole 260;

[0048] The top end of the sleeve 210 is connected to the upper end of the piston rod 120, and the length of the sleeve 210 is greater than the length of the piston rod 120;

[0049] Use of the cooling assembly 200;

[0050] The air cooler is connected to the air inlet pipe 240, so that the cold air enters the inside of the sleeve 210 from the air inlet pipe 240. At this time, when the piston rod 120 moves upward, the second plug 230 and the first plug 220 are driven to move upward, the second plug 230 is separated from the through hole 260, and the first plug 220 enters the through hole 260, so that the cold air at the lower end of the sleeve 210 moves from the through hole 260 to the upper end of the sleeve 210 and contacts the piston rod 120, thereby cooling the piston rod 120. After completion, when the piston rod 120 moves downward, the piston rod 120 drives the sleeve 210 to move downward, and the sleeve 210 drives the first plug 220 and the second plug 230 to move downward, the first plug 220 disengages from the through hole 260, and the second plug 230 enters the through hole 260 to close the through hole 260. At this time, the cooled air is blocked at the upper end of the sleeve 210 and is discharged to the outside through the outlet pipe 250, and new cold air enters the lower end of the sleeve 210 from the inlet pipe 240.

[0051] Example 2

[0052] See also Figure 4 shown, and;

[0053] The movable assembly 300 is connected to the outer surface of the lower end of the cylinder 110;

[0054] The movable assembly 300 includes a support plate 310 connected to the outer surface of the lower end of the cylinder 110, a pressure sensor 320 connected to the upper end of the support plate 310, a telescopic spring 330 connected to the top end of the pressure sensor 320, and a movable plate 340 connected to the top end of the telescopic spring 330;

[0056] Performing use of the active component 300;

[0057] When the piston rod 120 drives the sleeve 210 to move downward, the sleeve 210 drives the movable plate 340 to move downward, and the movable plate 340 drives the telescopic spring 330 to be compressed. At this time, the pressure sensor 320 measures the elastic force of the telescopic spring 330. Since the piston rod 120 is buffered by the buffer mechanism inside the cylinder 110, the elastic force of the telescopic spring 330 remains fixed. When the buffer mechanism fails, the elastic force of the telescopic spring 330 will increase, thereby judging the state of the buffer mechanism.
