Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and more specifically, to a hydraulic cylinder with a heating function. Background Technology

[0002] A hydraulic cylinder is a mechanical device that uses hydraulic oil as a power source. It is widely used in various industrial equipment and machinery. Its main function is to convert hydraulic energy into mechanical energy to achieve linear motion. The working principle of a hydraulic cylinder is that the hydraulic system pumps hydraulic oil to one end of the cylinder to realize oil inlet or oil return operations, so that the piston rod can extend and retract within the hydraulic cylinder body.

[0003] However, when using hydraulic cylinders in winter rain and snow, the surface of the piston rod and the connection between the piston rod and the hydraulic cylinder body are prone to ice formation due to the low temperature. The ice layer will increase the resistance between the piston rod and the cylinder body, and at the same time cause the piston rod to jam, making the extension and retraction of the piston rod more difficult. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a hydraulic cylinder with a heating function to solve the problem that when using a hydraulic cylinder in winter rain and snow, the surface of the piston rod and the connection between the piston rod and the hydraulic cylinder body are prone to ice formation due to the low temperature. The ice layer will increase the resistance between the piston rod and the cylinder body, and at the same time cause the piston rod to jam, making the extension and retraction of the piston rod more difficult.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a hydraulic cylinder with heating function, including a hydraulic cylinder body and a piston rod that extends and retracts on the hydraulic cylinder body, a heating sleeve is sleeved on the outer side of the piston rod, and the heating sleeve is provided with a heat-generating component for heating and a moving component that can drive the heating sleeve to move along the surface of the piston rod.

[0006] The air-heating component includes a heating groove formed inside the heating sleeve, and a heating wire is installed inside the heating groove.

[0007] Preferably, the inner side of the heating sleeve has a plurality of air guide pipes in a uniform annular array. The air guide pipes are connected to the heating tank. The end of the air guide pipes away from the heating tank is fixedly connected to a high-pressure air nozzle. The outer side of the heating sleeve is fixedly installed with air guide pipes. The air guide pipes are connected to the heating tank. The end of the air guide pipes away from the heating tank is fixedly connected to an air pump.

[0008] Preferably, the number of high-pressure air nozzles is at least four.

[0009] Preferably, the second air duct is made of a soft plastic tube.

[0010] Preferably, the moving component includes a drive motor and a first shaft. The drive motor is fixedly installed inside the heating sleeve, and the first shaft is rotatably connected inside the heating sleeve. The drive motor drives the first shaft to rotate. The first shaft has symmetrical worm gears. The second shaft, perpendicular to the first shaft, is also symmetrically rotatably connected inside the heating sleeve. A worm wheel is fixedly installed on one side of the second shaft, and a gear is fixedly installed on the other side of the second shaft. The worm wheel meshes with the worm gears. A moving wheel is symmetrically rotatably connected to the inner side of the heating sleeve. The moving wheel has teeth in the middle, and the gear meshes with the teeth. Ball protrusions are evenly distributed on both sides of the teeth on the moving wheel. The moving wheel can roll along the surface of the piston rod through the ball protrusions.

[0011] Preferably, the ball bump is made of elastic rubber material and the ball bump is higher than the tooth pattern.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention relates to a heating wire that generates heat when energized, which in turn heats the heating sleeve, thereby melting the ice layer at the connection between the hydraulic cylinder and the piston rod, as well as on the surface of the piston rod. The moving component drives the heating sleeve to move along the surface of the piston rod, which can uniformly heat the piston rod. Using the above structure, ice is melted on the surface of the piston rod and at the connection between the hydraulic cylinder and the piston rod, thereby avoiding piston rod jamming and making the extension and retraction of the piston rod more difficult.

[0014] This invention uses an air pump to pump air into the heating tank through the second air duct. The air is heated by the heating wire and then sprayed onto the piston rod through the first air duct and a high-pressure air nozzle. This melts the ice layer on the piston rod surface and blows out ice fragments and snow from the inside of the heating jacket, further improving the de-icing effect.

[0015] This invention uses a drive motor to drive the shaft to rotate, causing two moving wheels to rotate in opposite directions. Through the friction between the ball protrusion and the piston rod, the air-heating component is driven to melt the ice on the surface of the piston rod. With the above structure, it can be adapted to any length of the piston rod, and the teeth and ball protrusion can crush the ice layer on the surface of the piston rod, making it easier to crush the ice layer and improve the de-icing effect.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a hydraulic cylinder with a heating function, including a hydraulic cylinder body 1 and a piston rod 2 that extends and retracts on the hydraulic cylinder body 1. A heating sleeve 3 is sleeved on the outside of the piston rod 2. The heating sleeve 3 is provided with a heat-generating component 4 for heating and a moving component 5 that can drive the heating sleeve 3 to move along the surface of the piston rod 2.

[0023] The air-heating component 4 includes a heating groove 41 formed inside the heating sleeve 3, and a heating wire 42 is installed inside the heating groove 41.

[0024] Specifically, the heating wire 42 is energized and heats up, which in turn heats up the heating sleeve 3, thereby melting the ice layer at the connection between the hydraulic cylinder 1 and the piston rod 2 and on the surface of the piston rod 2. The moving component 5 drives the heating sleeve 3 to move along the surface of the piston rod 2, which can heat the piston rod 2 evenly.

[0025] Furthermore, the inner side of the heating sleeve 3 has a uniform annular array of several air guide pipes 43. The air guide pipes 43 are connected to the heating tank 41. The end of the air guide pipes 43 away from the heating tank 41 is fixedly connected to a high-pressure air nozzle 44. The outer side of the heating sleeve 3 is fixedly installed with an air guide pipe 45. The air guide pipe 45 is connected to the heating tank 41. The end of the air guide pipe 45 away from the heating tank 41 is fixedly connected to an air pump 46.

[0026] Specifically, air is pumped into the heating tank 41 through the air pump 46 via the second air duct 45, heated by the heating wire 42, and then sprayed onto the piston rod 2 through the first air duct 43 and the high-pressure air nozzle 44. This melts the ice layer on the surface of the piston rod 2 and blows out ice fragments and snow from the inside of the heating jacket 3, improving the de-icing effect.

[0027] Preferably, the number of high-pressure air nozzles 44 is at least four.

[0028] Preferably, the second air duct 45 is made of soft plastic tubing so that the second air duct 45 can adapt to the displacement of the heating sleeve 3, and at the same time, it is also easy to adapt to the installation position of the air pump 46.

[0029] Furthermore, the moving component 5 includes a drive motor 51 and a first shaft 52. The drive motor 51 is fixedly installed inside the heating sleeve 3, and the first shaft 52 is rotatably connected inside the heating sleeve 3. The drive motor 51 is used to drive the first shaft 52 to rotate. The first shaft 52 is provided with symmetrical worm gears 53. The second shaft 54, which is perpendicular to the first shaft 52, is also symmetrically rotatably connected inside the heating sleeve 3. A worm gear 55 is fixedly installed on one side of the second shaft 54, and a gear 56 is fixedly installed on the other side of the second shaft 54. The worm gear 55 meshes with the worm gears 53. A moving wheel 57 is symmetrically rotatably connected to the inner side of the heating sleeve 3. The moving wheel 57 is provided with teeth 58 in the middle. The gear 56 meshes with the teeth 58. Ball protrusions 59 are evenly distributed on both sides of the teeth 58 on the moving wheel 57. The moving wheel 57 can roll along the surface of the piston rod 2 through the ball protrusions 59.

[0030] Specifically, the drive motor 51 drives the shaft 52 to rotate, causing the worm gear 53 to mesh with the worm wheel 55, so that the two shafts 54 on both sides rotate in opposite directions. At the same time, the gear 56 meshes with the tooth pattern 58, causing the two moving wheels 57 to rotate in opposite directions. Through the friction between the ball protrusion 59 and the piston rod 2, the air-heating assembly 4 drives the piston rod 2 to melt ice on its surface.

[0031] Both the toothed pattern 58 and the ball bump 59 can crush the ice layer on the surface of the piston rod 2, making it easier to break up the ice layer and improve the de-icing effect.

[0032] Furthermore, when the ice layer is thick at a certain point on the piston rod 2, hindering the movement of the heating sleeve 3, the rotating wheel 57 causes the ball protrusion 59 to rub against the piston rod 2, generating heat and thus accelerating the melting of the ice layer.

[0033] Preferably, the ball bump 59 is made of elastic rubber and is higher than the tooth pattern 58, so that there is a large friction between the ball bump 59 and the piston rod 2.

[0034] The working process of this utility model is as follows:

[0035] In use, the heating wire 42 is energized and heats up, causing the heating sleeve 3 to heat up. Then, the air pump 46 pumps air into the heating tank 41 through the second air duct 45. After being heated by the heating wire 42, the air is sprayed onto the piston rod 2 through the first air duct 43 and the high-pressure air nozzle 44 to melt the ice layer on the surface of the piston rod 2. Then, the drive motor 51 drives the shaft 52 to rotate, causing the two moving wheels 57 to rotate in opposite directions. Through the friction between the ball protrusion 59 and the piston rod 2, the air-heating component 4 moves evenly along the surface of the piston rod 2 to melt the ice on the surface of the piston rod 2. After the de-icing is completed, the heating sleeve 3 is moved to the connection between the hydraulic cylinder 1 and the piston rod 2.
