Through this assembly, the gear box cover mechanical energy can be quickly disassembled and assembled.

[0006] Preferably, the upper detection port assembly comprises: a baffle groove, a slideway, an upper baffle, a slide rail and a concave handle;

[0007] The baffle groove is opened on the gear box cover, the slide is opened on both sides of the baffle groove, the upper baffle is installed in the slide through the slide rail, and the concave handle is installed on the upper baffle. This component can be used to detect the opening point of the gear box cover, thereby coping with routine inspections without removing the gear box cover.

[0008] Preferably, the baffle locking assembly comprises: a buckle slot, a locking buckle, a switch buckle and a spring;

[0009] The buckle slot is opened on the gear box cover, the locking buckle is installed on the front end of the upper baffle, the spring is installed in the buckle slot and rests against the bottom of the locking buckle, the switch buckle is installed in the buckle slot and engages with the locking buckle, and the upper baffle can be quickly disassembled and assembled through this component.

[0010] Preferably, a handle is provided on the side of the gear box cover.

[0011] Preferably, a transparent area is provided on the upper baffle.

[0012] Beneficial Effects

[0013] The gearbox group which is convenient for maintenance has the following beneficial effects:

[0014] In this case, the upper half of the gear box cover can be removed and lifted vertically through the unpacking inspection assembly, and then supported by the baffle locking assembly, so that the threaded holes can be quickly aligned for assembly when the gear box cover is installed. The upper inspection port assembly can open the inspection port of the gear box cover without removing the gear box cover, thereby coping with some routine inspections that do not require removal of the gear box cover.
