Description

Technical Field

[0001] This utility model relates to the field of port machinery protection technology, and in particular to a protective cover for the drive shaft of a bridge crane. Background Technology

[0002] Existing protective covers for bridge crane drive shafts mostly use iron or simple metal structures, which have many drawbacks. Firstly, iron covers are highly susceptible to rust and corrosion in harsh environments such as humidity and salt spray, affecting not only their appearance but also their structural strength, posing a threat to the safe operation of the equipment. Furthermore, they require frequent rust prevention treatments, increasing maintenance costs and workload. Secondly, the weight of metal materials makes installation and transportation extremely inconvenient, while also adding to the load on the bridge crane equipment, negatively impacting its overall operating efficiency and energy consumption. In addition, metal protective covers may generate electromagnetic interference with some precision electronic devices on the bridge crane, affecting their normal operation and signal transmission, thus adversely affecting the accuracy and reliability of the entire bridge crane operation. Utility Model Content

[0003] The main objective of this invention is to provide a protective cover for the drive shaft of a bridge crane, which addresses the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A protective cover for a bridge crane drive shaft includes a main body. The main body comprises a first arched section and a second arched section made of fiberglass. The second arched section is symmetrically connected to both sides of the first arched section, and arched openings are formed on the sides of the second arched sections. An inspection port is formed at the top of the second arched section, and an inspection cover is hinged to the inspection port. An EPE buffer layer is fitted to the inner wall of the first arched section, and buffer strips cover the edges of the arched openings.

[0006] Furthermore, the second arched section has heat dissipation holes on its side, which are arranged around the arched opening, and a filter screen is embedded in the heat dissipation holes.

[0007] Furthermore, the surfaces of the first and second arched sections are coated with an anti-UV gel coat layer, the thickness of which is 0.3 mm. Anti-UV gel coat is a special coating or coating material designed to provide an additional layer of UV protection, extending the service life of fiberglass products.

[0008] Furthermore, the EPE buffer layer is made of closed-cell foamed polyethylene, and the thickness of the EPE buffer layer is 10mm.

[0009] Furthermore, one side of the inspection cover is provided with a hinge that is hinged to the second arched part, and the other side of the inspection cover is provided with a buckle that is engaged with the second arched part.

[0010] This utility model also includes other components that enable the protective cover for the bridge crane's drive shaft to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not limited in this utility model all employ conventional techniques in the art, such as the filter screen mentioned in this application. In specific implementation, appropriate device or component models can be selected according to the specific working scenario.

[0011] The working principle of this utility model is as follows: The main body of the protective cover is made of corrosion-resistant fiberglass. The first and second arched sections provide stable protection for the drive shaft through a specific structure. The EPE buffer layer on the inner wall and the buffer strips along the edges of the arched openings effectively buffer impacts and protect the drive shaft. The inspection port and inspection cover facilitate maintenance, the heat dissipation holes facilitate heat dissipation and the filter screen prevents debris from entering, and the UV-resistant gel coat layer resists UV aging. All components work together to achieve the protective function.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Improved corrosion resistance: The combination of fiberglass material and UV-resistant gel coat layer improves corrosion resistance and anti-aging ability, reduces maintenance and extends the life of the protective cover;

[0014] 2. Reduce equipment load: The fiberglass material reduces the weight of the protective cover, making it easier to install and move, thus reducing the load on the equipment.

[0015] 3. Enhanced buffering effect: The EPE buffer layer and buffer strip work together to buffer vibration and impact, protect the drive shaft for stable operation, and reduce electromagnetic interference to ensure equipment accuracy. Attached Figure Description
