[0026] Firstly, the dust cleaning device of the utility model includes symmetrically arranged cleaning scraper 1.The cleaning scraper 1 is the main working component of the dust cleaning device, which is used to scrape off the dust adhering to the rigid composite slide wire.The cleaning scraper 1 is preferably made of polyurethane material, because polyurethane has good wear resistance and elasticity, and can maintain good dust scraping effect and durability during long-term use.The shape and size of the cleaning scraper 1 are designed according to the shape and size of the rigid composite slide wire, to ensure that the cleaning scraper 1 can be in close contact with the rigid composite slide wire and effectively remove dust.

[0027] The inner side of the cleaning scraper 1 is provided with a scraper limiting sleeve 4.The scraper limiting sleeve 4 is installed on the scraper fixing shaft 2 through the scraper mounting pin 3.The function of the scraper limiting sleeve 4 is to limit the position of the cleaning scraper 1 on the scraper fixing shaft 2, to prevent the cleaning scraper 1 from shifting or shaking during dust scraping, affecting the dust scraping effect.The scraper mounting pin 3 passes through the holes of the cleaning scraper 1 and the scraper limiting sleeve 4, and fixes the cleaning scraper 1 and the scraper limiting sleeve 4 on the scraper fixing shaft 2.The number and position of the scraper mounting pin 3 are designed according to the size and shape of the cleaning scraper 1, to ensure that the cleaning scraper 1 can be stably fixed on the scraper fixing shaft 2.

[0028] With reference to Figure 3 In order to further enhance the fixing effect of the cleaning blade 1, the outer side of the cleaning blade 1 is also provided with a blade fastening washer 5 and a blade fastening nut 6. The blade fastening washer 5 is placed on the outer side of the cleaning blade 1, and the blade fastening nut 6 is screwed on the threads at both ends of the blade mounting pin 3. The blade fastening washer 5 and the blade fastening nut 6 increase the friction between the cleaning blade 1 and the blade mounting pin 3, preventing the cleaning blade 1 from loosening or falling off during use.

[0029] Next, the ash cleaning device of the present embodiment also includes a blade fixing shaft 2 connected to the inner side of the cleaning blade 1. The blade fixing shaft 2 is a supporting component of the cleaning blade 1, used to fix the cleaning blade 1 on the telescopic assembly. The shape and size of the blade fixing shaft 2 are designed according to the shape and size of the cleaning blade 1 to ensure that the cleaning blade 1 can be stably fixed on the blade fixing shaft 2. The material of the blade fixing shaft 2 is preferably high-strength alloy steel to ensure that it has sufficient strength and rigidity during use.

[0030] The tail end of the blade fixing shaft 2 is connected to the telescopic assembly. The telescopic assembly adjusts the distance between the cleaning blade 1 and the rigid composite slide wire to adapt to different thicknesses of dust and different degrees of wear of the cleaning blade 1. The telescopic assembly includes a telescopic shaft 8 connected to the tail end of the blade fixing shaft 2. The shape and size of the telescopic shaft 8 are designed according to the shape and size of the blade fixing shaft 2 to ensure that the telescopic shaft 8 can be stably connected to the blade fixing shaft 2. The material of the telescopic shaft 8 is preferably high-strength alloy steel to ensure that it has sufficient strength and rigidity during use.

[0031] The telescopic shaft 8 is externally sleeved with a telescopic shaft sleeve 9 and a spring 14. The telescopic shaft sleeve 9 supports the telescopic shaft 8 and limits the movement range of the telescopic shaft 8. The shape and size of the telescopic shaft sleeve 9 are designed according to the shape and size of the telescopic shaft 8 to ensure that the telescopic shaft 8 can move stably within the telescopic shaft sleeve 9. The material of the telescopic shaft sleeve 9 is preferably wear-resistant alloy steel to improve its service life. The spring 14 is sleeved at the tail of the telescopic shaft 8 to provide a pressing force of the cleaning blade 1 on the rigid composite slide wire. The material and specifications of the spring 14 are designed according to the weight of the cleaning blade 1 and the hardness of the rigid composite slide wire to ensure that the cleaning blade 1 can be tightly attached to the rigid composite slide wire.

[0032] With reference to Figure 4The side end of the telescopic shaft sleeve 9 is provided with a limiting groove, and the telescopic shaft 8 is provided with telescopic shaft limiting screws 13. The telescopic shaft limiting screws 13 limit the movement distance of the telescopic assembly through the limiting groove. The shape and size of the limiting groove are designed according to the movement range of the telescopic shaft 8, so as to ensure that the telescopic shaft 8 will not exceed the predetermined range during movement. The number and position of the telescopic shaft limiting screws 13 are designed according to the shape and size of the limiting groove, so as to ensure that the telescopic shaft limiting screws 13 can effectively limit the movement of the telescopic shaft 8.

[0033] In order to fix the telescopic assembly on the crane cage, the outer side of the telescopic shaft sleeve 9 is sleeved with a telescopic sleeve fixing clamp 10. The opposite side of the telescopic sleeve fixing clamp 10 is provided with a mounting plate 12, and the telescopic sleeve fixing clamp 10 and the mounting plate 12 are connected together through two telescopic sleeve fixing screws 11. The shape and size of the mounting plate 12 are designed according to the shape and size of the crane cage, so as to ensure that the mounting plate 12 can be stably fixed on the crane cage. The number and position of the telescopic sleeve fixing clamp 10 are designed according to the shape and size of the telescopic shaft sleeve 9, and in the embodiment, the number of the telescopic sleeve fixing clamp 10 is two, so as to ensure that the telescopic sleeve fixing clamp 10 can effectively fix the telescopic shaft sleeve 9 on the mounting plate 12.

[0034] Referring to Figure 5 At the tail of the telescopic shaft 8, a spring limiting cap 15 and a telescopic shaft limiting nut 16 are further provided. The spring limiting cap 15 limits the telescopic distance of the spring 14, so as to prevent the spring 14 from being excessively elongated or compressed during telescopic process, and affect the pressing force of the cleaning scraper 1 on the rigid composite slide wire. The shape and size of the spring limiting cap 15 are designed according to the shape and size of the spring 14, so as to ensure that the spring limiting cap 15 can effectively limit the telescopic range of the spring 14. The telescopic shaft limiting nut 16 is screwed into the tail end thread of the telescopic shaft 8, and is used for adjusting the displacement amount of the telescopic shaft 8 relative to the telescopic shaft sleeve 9. By adjusting the screwing depth of the telescopic shaft limiting nut 16, the movement range of the telescopic shaft 8 in the telescopic shaft sleeve 9 can be controlled, and then the distance between the cleaning scraper 1 and the rigid composite slide wire is adjusted.

[0035] At the connection between the scraper fixing shaft 2 and the telescopic shaft 8, a fixing shaft pin 7 is further provided. The function of the fixing shaft pin 7 is to fixedly connect the scraper fixing shaft 2 and the telescopic shaft 8 together, so as to prevent the relative movement or rotation of the scraper fixing shaft 2 and the telescopic shaft 8 during dust cleaning process. The number and position of the fixing shaft pin 7 are designed according to the shape and size of the scraper fixing shaft 2 and the telescopic shaft 8, so as to ensure that the fixing shaft pin 7 can effectively fix the scraper fixing shaft 2 and the telescopic shaft 8 together.

[0036] In the installation of the dust cleaning device, first, the cleaning scraper 1, the scraper limiting sleeve 4, the scraper mounting pin 3, the scraper fastening gasket 5 and the scraper fastening nut 6 are assembled together to form a cleaning scraper assembly. Then the cleaning scraper assembly is connected together through the scraper fixing shaft 2 and the fixing shaft snap pin 7 and the telescopic shaft 8. Next, the telescopic shaft 8 is sleeved into the telescopic shaft sleeve 9, and the telescopic shaft 8 and the telescopic shaft sleeve 9 are connected together through the telescopic shaft limiting screw 13. Then the spring 14 is sleeved at the tail of the telescopic shaft 8, and the spring 14 is fixed on the telescopic shaft 8 through the spring limiting cap 15 and the telescopic shaft limiting nut 16. Finally, the telescopic shaft sleeve 9 and the mounting plate 12 are connected together through the telescopic sleeve fixing clamp 10 and the telescopic sleeve fixing screw 11 to form a complete dust cleaning device. After the dust cleaning device is fixed on the crane cage, it can be used.

[0037] In the use process, when the bridge crane moves, the cleaning scraper 1 contacts the rigid composite slide wire and scrapes off the dust attached to the slide wire. Due to the compression effect of the spring 14, the cleaning scraper 1 is always closely attached to the rigid composite slide wire, ensuring the dust scraping effect. When the cleaning scraper 1 is worn after a long period of use, due to the compression effect of the spring 14, the telescopic shaft 8 will be displaced forward relative to the telescopic shaft sleeve 9, thereby driving the scraper fixing shaft 2 and the cleaning scraper 1 to displace forward, compensating for the wear. In this way, the cleaning scraper 1 can always contact the conductive surface of the rigid composite slide wire, playing a dust cleaning role.

[0038] The dust cleaning device of the embodiment has the advantages of simple structure, convenient installation and good use effect. By adjusting the moving distance of the telescopic assembly and the distance between the cleaning scraper 1 and the rigid composite slide wire, the dust cleaning device can adapt to dust of different thicknesses and cleaning scrapers 1 of different wear degrees. At the same time, since the cleaning scraper 1 is made of polyurethane material, it has good wear resistance and elasticity, and can maintain good dust scraping effect and durability during long-term use. Therefore, the dust cleaning device can significantly improve the service life and safety of the rigid composite power supply slide wire of the bridge crane.

[0039] In addition, the dust cleaning device of the embodiment can also be customized and improved according to actual needs. For example, different shapes and sizes of cleaning scrapers 1 can be designed according to the shape and size of the rigid composite slide wire; different shapes and sizes of mounting plates 12 can be designed according to the shape and size of the crane cage; and the number and spacing of the cleaning scrapers 1 can also be increased or decreased according to actual needs. These improvements and customizations can make the dust cleaning device more adaptable to different use environments and needs.

[0040] In summary, the rigid composite power supply slide wire dust cleaning device of the bridge crane realizes effective scraping of dust on the rigid composite slide wire conductive surface and compensation of wear amount through adoption of polyurethane cleaning scraper, telescopic assembly and spring pressing mechanism and the like design.

[0041] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
