Description

Technical Field

[0001] The utility model relates to the technical field of overhaul and maintenance of a winch-type door hoist, and more specifically to a lubricating grease collecting device for an open-type gear of a door hoist. Background Art

[0002] In water conservancy and hydropower projects, especially various hydraulic gate projects, winch hoists such as gantry cranes, bridge cranes, fixed coils, and trolleys are widely used to hoist gates or parts. Open gear transmission is a transmission with a simple structure, good ventilation and heat dissipation performance, and large load transmission. It is widely used in the lifting mechanism of such winch hoists.

[0003] In order to ensure the stability of open gear transmission, it is necessary to provide sufficient lubrication and apply grease on its surface regularly. When it is running, the excess grease will be thrown onto the surface of the equipment or the ground. In a high temperature environment, the grease of the stationary gear will also drip. The dripping grease will not only pollute the ground and the environment, but also have an adverse effect on the precision parts of the hoisting.

[0004] In a gantry machine, since the lower side of the open teeth is usually exposed to the air, there is a problem of grease splashing and dripping on the open teeth. In the prior art, an anti-oil cloth is often pulled under the open teeth to collect the grease. This method is very easy to be involved in the running gear pair when the winch-type gate hoist is working, causing safety accidents. The method needs to be removed before the equipment is operated, which increases the labor intensity of the operators. Utility Model Content
