[0029] Reference below Figure 1 A hydraulic cylinder cooling and dust removal device 100 and a hydraulic cylinder 1000 according to an embodiment of the present invention are described.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a hydraulic cylinder cooling and dust removal device 100, which includes an air pipe 1 and a purge assembly 2. The air pipe 1 has an air inlet and an air outlet. Compressed gas enters the air pipe 1 through the air inlet. The air outlet of the air pipe 1 is connected to the purge assembly 2, and the compressed gas is ejected from the purge assembly 2 and blown to the movable joint of the hydraulic cylinder 1000.

[0032] It should be further explained that the purge assembly 2 has an air outlet for ejecting air. When installing and debugging the purge assembly, the installer needs to align the air outlet of the purge assembly with or diagonally toward the movable joint of the hydraulic cylinder 1000 to guide the compressed gas to be ejected into the movable joint of the hydraulic cylinder 1000.

[0033] In one specific example, the purge assembly 2 includes a nozzle and an adapter. The outlet end of the air pipe 1 is connected to one end of the adapter, and the nozzle is connected to the other end of the adapter. The adapter contains an airflow channel connecting the air pipe 1 and the nozzle. The nozzle faces directly or diagonally to the articulation of the hydraulic cylinder 1000. Therefore, the compressed air flows through the air pipe 1 and the adapter in sequence, and finally ejected from the nozzle to the articulation of the hydraulic cylinder 1000. The nozzle can concentrate the airflow and can face directly or diagonally to the articulation of the hydraulic cylinder 1000 to increase the purge area.

[0034] The adapter can be an air pipe joint or an adapter tube. The adapter tube and the air pipe extend in different directions and can rotate relative to each other, thereby adjusting the angle and position of the nozzle jet airflow.

[0035] like Figure 1 As shown, in a specific application scenario, a hydraulic cylinder 1000 includes a cylinder 200 and a piston rod 300. The piston rod 300 is mounted within the cylinder 200 and reciprocates linearly relative to the cylinder 200. During operation, dust accumulates at the joint between the cylinder 200 and the piston rod 300, increasing friction between the cylinder 200 and the piston rod 300 and raising operating temperatures. If hydraulic cylinder 1000 continues to operate under these conditions, the dust and high temperatures could damage it.

[0036] like Figure 1 As shown, the applicant has designed a hydraulic cylinder cooling and dust removal device 100, which introduces compressed gas from the air inlet end of the air pipe 1, and the compressed gas is sent from the air outlet of the blowing component 2 to the movable connection of the hydraulic cylinder 1000, so as to remove dust and reduce the temperature in time, which is beneficial to the damage of dust and high temperature to the hydraulic cylinder 1000. Although there are dedicated operation and maintenance personnel to maintain the hydraulic cylinder 1000, the installation position of some hydraulic cylinders 1000 is narrow and cannot be fully covered by manual labor, so there may be situations where maintenance is not in place. Compared with manual maintenance, the hydraulic cylinder cooling and dust removal device 100 occupies a small space and can reach locations that are difficult to reach manually, reducing manual maintenance, reducing labor intensity and helping to reduce the loss of the hydraulic cylinder 1000, thereby reducing the failure rate of the hydraulic cylinder 1000 and saving costs.

[0037] It should be further explained that the compressed gas can be the compressed air commonly used in power plants to purge and cool the hydraulic cylinder 1000, thereby reducing the cost of transformation.

[0038] like Figure 1 As shown, the hydraulic cylinder cooling and dust removal device 100 further includes an on-off valve 3, which is installed on the air pipe 1. The on-off valve 3 is used to control the on or off of the air pipe 1, thereby controlling the dust removal or cooling process.

[0039] like Figure 1 As shown, the on-off valve 3 is a solenoid valve; the hydraulic cylinder cooling and dust removal device 100 also includes a timer 4, which is electrically connected to the solenoid valve. The timer 4 can be a time relay, which is electrically connected to the solenoid valve to control the connection and closing time of the air pipe 1, thereby automating the periodic purge.

[0040] Furthermore, the pressure of the compressed gas is at least 0.3 MPa.

[0041] Furthermore, the hydraulic cylinder cooling and dust removal device 100 also includes an air storage device, which is used to store compressed gas and is connected to the air inlet end of the air pipe 1.

[0042] In some specific examples, the operation and maintenance personnel first open the valve of the gas storage device to pass the compressed gas into the gas pipe 1; secondly, set the timer 4 to control the solenoid valve with regular purge time; finally, change the regular time according to the stroke and time of the on-site hydraulic cylinder 1000.

[0043] Example 2

[0044] like Figure 1 As shown, this embodiment is substantially the same as the first embodiment, except that the purge assembly 2 includes a fan-shaped nozzle 21 connected to the air outlet. The fan-shaped nozzle 21 is connected to the air outlet end of the air pipe 1 to spray air toward the movable joint of the hydraulic cylinder 1000. The fan-shaped nozzle 21 has a larger blowing area, which can improve the efficiency of dust removal.

[0045] like Figure 1 As shown, the hydraulic cylinder cooling and dust removal device 100 further includes a dust cover 5, which is arranged to cover the movable joint of the hydraulic cylinder 1000, and the fan-shaped nozzle 21 is located between the hydraulic cylinder 1000 and the dust cover 5. On the one hand, the dust cover 5 can reduce the adhesion of dust on the movable joint of the hydraulic cylinder 1000; on the other hand, the dust cover 5 can direct the airflow of the fan-shaped nozzle 21 toward the hydraulic cylinder 1000, thereby improving the efficiency of the compressed gas in removing dust.

[0046] like Figure 1 As shown, in a specific example, the dust cover 5 is extended around the outer ring of the hydraulic cylinder 1000, and the extension length of the dust cover 5 is half of the circumference of the hydraulic cylinder 1000. The shape of the dust cover 5 is customized according to the actual situation on site, and can be conical, cylindrical or other shapes.

[0047] Furthermore, the dust cover 5 is made of stainless steel.

[0048] like Figure 1 As shown, the hydraulic cylinder cooling and dust removal device 100 further includes a magnetic member 6, which is fixedly connected to the dust cover 5. The dust cover 5 is removably mounted on the cylinder 200 of the hydraulic cylinder 1000 via the magnetic member 6. The dust cover 5 is fixed to the hydraulic cylinder 1000 by the magnetic member 6, which improves the convenience of removing and installing the dust cover 5. When the dust cover 5 is removed from the hydraulic cylinder 1000, it is convenient to clean the dust cover 5.

[0049] Example 3

[0050] like Figure 1 As shown, this embodiment provides a hydraulic cylinder 1000, which includes a cylinder 200, a piston rod 300 and a hydraulic cylinder cooling and dust removal device 100. The piston rod 300 is movably connected to the cylinder 200, and the air pipe 1 is connected to the purge assembly 2 to spray airflow to the movable connection of the hydraulic cylinder 1000.

[0051] The remaining configuration and operation of the hydraulic cylinder 1000 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here. In the description of the present invention, "first feature" and "second feature" may include one or more of these features.

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is at a higher level than the second feature.
