Detailed Description

The technical solutions of the present invention will be described in further detail with reference to the following specific embodiments, but the present invention is not limited to the following technical solutions.

Examples

As shown in fig. 1, the outdoor belt wiper device includes a driving device 11, a blade holder 6, and a fixed bracket device 3, wherein the blade holder 6 is composed of a support rod 7, a hydraulic push rod 8, a scraper 9, and a connection rod 10, the support rod 7 is fixed on a belt conveyor frame 1, the driving device 11 is fixed on the support rod 7, one end of the hydraulic push rod 8 is movably connected with the driving device 11, one end of the connection rod 10 is movably connected with the driving support rod 7, the hydraulic push rod 8 and the other end of the connection rod 10 are respectively movably connected with the scraper 9, the fixed bracket device 3 is composed of a bearing bracket 5 and a wear-resistant plate 4, the wear-resistant plate 4 is placed on the bearing bracket 5, the bearing bracket 5 is welded on the belt conveyor frame 1, the lower surface of a belt 2 is attached to the upper surface of the fixed bracket device 3, and the height of the fixed bracket device 3 is matched with the height of, so that the lower surface of the adhesive tape 2 is attached to the upper surface of the wear plate 4 after the scraper 9 is dropped.

As shown in fig. 2, the fixing bracket device 3 may be provided to be adjustable in height, preferably 10mm in distance from the upper surface of the fixing bracket device 3 to the adhesive tape 2, depending on the adhesive tape machine (conveyor belt) used. The width of the fixing bracket device 3 is the same as that of the belt conveyor frame 1, and the length is the same as that of the scraper 9. The bearing bracket 5 of the fixed bracket is welded by angle steel of 70 to be made into a tray shape, the depth of the tray is less than the thickness of the wear-resisting plate 4, and the adhesive tape 2 can not rub the edge of the bearing bracket 5. The wear-resisting plate 4 is made of a polytetrafluoroethylene plate with the thickness of 100mm, and other wear-resisting plates can be adopted. The wear plates 4 are sized to correspond to the inner diameter of the tray carrying the carrier 5, and the wear plates 4 are placed in the tray carrying the carrier 5.

When the device is used, the position of the scraper 9 after falling is determined, the gaps of the carrier rollers on two sides after the carrier roller at the corresponding position on the frame 1 of the adhesive tape machine needs to be removed, and the distance between the position of the scraper 9 after falling and the surface of the adhesive tape 2 to be tightly attached and the frame 1 of the adhesive tape machine are determined, so that the fixed bracket device 3 with the required corresponding size is designed. And then fixedly installing the manufactured fixing bracket device 3 on the frame 1 of the adhesive tape machine in a welding mode, or connecting the manufactured fixing bracket device with bolts after punching holes at corresponding positions, and adopting other fixing connection modes.

In view of further improvement of the above technical solution, an object to be solved is to provide a device for reducing friction, so as to reduce the contact area between the adhesive tape 2 and the wear-resistant plate 4, thereby prolonging the service life of the adhesive tape 2 and the wear-resistant plate 4.

For this purpose, in a further modification of this embodiment, as shown in fig. 3, 3 flat idlers 12 are disposed at front, middle and rear positions of the fixed bracket device 3, the flat idlers 12 are connected by idler lugs 13, the idler lugs 13 are welded to the carrier bracket 5, the wear plates 4 are two and are respectively placed in the gaps of the 3 flat idlers 12, and the height of the parallel surface of the flat idlers 12 and the wear plates 4 is higher than that of the wear plates 4, so that the flat idlers 12 can support the adhesive tape 2 and move together with the adhesive tape 2. In practice, more than 3 flat idlers 12 may be provided, depending on the length of the fixed bracket device 3. The flat carrier roller 12 is connected through the carrier roller ear 13 and is easy to replace, and the service life of the fixed bracket device 3 is prolonged and can reach more than 5 years.

The working principle and the process are as follows:

the water scraping device is arranged at the position of 8 meters of a funnel inlet of the head of the sealing-tape machine and is welded on the frame 1 of the sealing-tape machine. When the automatic water scraping device works, the adhesive tape 2 moves along with the upper supporting roller of the adhesive tape machine, the driving device 11 drives the hydraulic push rod 8 to push the scraper 9 to be attached to the adhesive tape 2 at the moment, the fixed bracket device 3 supports the adhesive tape 2 to enable the adhesive tape 2 to be flat, and the scraper 9 is matched with the fixed bracket device 3 to scrape water along with the movement of the adhesive tape 2. After the improved fixing bracket device 3 is adopted, the flat carrier roller 12 in the fixing bracket device 3 moves along with the adhesive tape 2, the flat carrier roller 12 and the wear-resistant plate 4 support the adhesive tape 2 and the adhesive tape 2, the flat carrier roller 12 supports the scraper 9 and scrapes water, the contact area of the wear-resistant plate and the adhesive tape is reduced, the friction between the wear-resistant plate and the adhesive tape is reduced, and the service lives of the adhesive tape and the wear-resistant plate are effectively prolonged.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
