[0044] Specifically, the protection device 10 comprises a protection cover 11, the protection cover 11 is configured to be arranged on the oil cylinder 21, and the protection cover 11 has a shielding space 1111 which is adapted to accommodate and shield the oil injection structure 212 of the oil cylinder 21.

[0045] For example, the protection device 10 is used on the oil cylinder 21, and it can be understood that the oil cylinder 21 comprises a cylinder body and a piston 211, wherein a part of the piston 211 extends into the cylinder body and can move relative to the cylinder body, and the oil injection structure 212 is arranged on the piston 211, and the protection device is arranged on the piston 211 and shields the oil injection structure 212.

[0046] The protection device 10 provided by the above-mentioned embodiment of the present application is arranged on the oil cylinder 21, and the shielding space 1111 of the protection device 10 shields the oil injection structure 212, so that the oil injection structure 212 is effectively protected by the protection device 10, and the risk of blockage, deformation and damage of the oil injection structure 212 is avoided, the frequency of maintenance is reduced, the service life of the oil injection structure 212 is prolonged, the reliability of the product is improved, and the protection device 10 has the advantages of simple structure and small size, so that the protection device 10 can better adapt to the limited installation space and realize compact layout.

[0047] It is worth noting that the oil cylinder 21 is used on the mechanical equipment 30, for example, the oil cylinder 21 is used on a coal mining machine, and the space layout of the coal mining machine is limited. By installing the protection cover 11 on the oil injection structure 212 of the oil cylinder 21 of the coal mining machine, the oil cylinder 21 of the coal mining machine can be well protected in the limited space.
