Description

Technical Field

[0001] The utility model relates to the field of belt conveyor mechanical equipment, in particular to a steel-plastic composite roller. Background Art

[0002] Rollers are important parts of belt conveyors. They are of many types and in large quantities. They can support the weight of the conveyor belt and materials. They account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance. Therefore, the quality of rollers is particularly important. They are made of steel and composite. The function of rollers is to support the weight of the conveyor belt and materials. The operation of rollers must be flexible and reliable. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor.

[0003] In order to ensure the wear resistance and corrosion resistance of the existing steel-plastic composite rollers, a wear-resistant layer is provided on the outside of the roller to improve the wear resistance of the roller. However, the wear-resistant layer is mostly fixed to the roller. When the wear-resistant layer is damaged, the entire roller needs to be replaced. It is inconvenient to remove and replace the wear-resistant layer separately, and the economy is not good. Utility Model Content

[0024] The wear-resistant jacket 4 is independently arranged outside the drum 2, the wear-resistant jacket 4 is installed on the outside of the drum 2, and is fixedly connected to the drum 2 from both sides by using a fixed plate 5, so that the fixed plate 5 limits the wear-resistant jacket 4 outside the drum 2 from both sides to prevent displacement, so that the wear-resistant jacket 4 and the drum 2 are independently arranged. When the wear-resistant jacket 4 is damaged, the wear-resistant jacket 4 can be removed and replaced separately from the outside of the drum 2 by removing the fixed plate 5, thereby avoiding the replacement of the entire drum 2 and improving the economy. At the same time, the wear-resistant jacket 4 and the drum 2 are independently arranged, and the fixed plate 5 can be used to carry away part of the heat through the external air flow when in use, thereby improving the heat dissipation effect.

[0025] like Figure 3 As shown, the drum 2 includes a main body 21 , an outer protruding horizontal bar 22 is arranged outside the main body 21 , and fixing holes 23 are opened on both left and right sides of the outer protruding horizontal bar 22 .

[0026] The outer protruding horizontal bar 22 is arranged outside the main body 21 to facilitate docking of the wear-resistant jacket 4 and to cooperate with the fixing hole 23 to connect with the fixing plate 5, so as to facilitate installation of the wear-resistant jacket 4.

[0027] like Figure 5 As shown, the wear-resistant outer sleeve 4 includes a wear-resistant layer 41 , a protrusion 42 is provided on the inner side of the wear-resistant layer 41 , a docking slot 43 is provided on the inner side of the protrusion 42 , the docking slot 43 is matched with the outer protruding horizontal bar 22 , and a corrosion-resistant layer 44 is provided on the outside of the wear-resistant layer 41 .

[0028] The protrusion 42 is provided with a docking slot 43 on the inner side thereof to connect with the drum 2, so that the wear-resistant jacket 4 is installed on the outside of the drum 2. When the wear-resistant jacket 4 is damaged, it is convenient to disassemble and replace the wear-resistant jacket 4 separately, thereby improving economy.

[0029] like Figure 3 As shown, the fixing plate 5 includes an outer chuck 51 , and the inner part of the outer chuck 51 is provided with docking holes 52 at equal intervals, and the outer side of the docking hole 52 is movably mounted with a fixing bolt 53 located in the fixing hole 23 .

[0030] The fixing bolts 53 are passed through the docking holes 52 to connect to the drum 2 , and the fixing bolts 53 are used to limit and fix the wear-resistant outer sleeve 4 located outside the drum 2 from the side.

[0031] like Figure 3 As shown, the main body 21 and the externally protruding horizontal bars 22 are integrally formed, and there are four externally protruding horizontal bars 22 equidistantly distributed outside the main body 21 .

[0032] Four externally protruding horizontal bars 22 are arranged at equal intervals to facilitate the docking, limiting and fixing of the wear-resistant outer jacket 4 .

[0034] The outer chuck 51 has openings 54 formed at equal intervals inside.

[0035] The gap and the opening 54 allow external air to circulate, taking away part of the heat generated during use, thereby improving the heat dissipation effect.

[0036] like Figure 2 As shown, sealing layers 6 are provided on both the inner and outer sides of the bearing 3 , and an outer retaining ring 7 is fixedly installed on the outer side of the drum 2 .

[0037] The sealing layer 6 ensures the sealing performance of the connection of the bearing 3 , and cooperates with the outer retaining ring 7 to achieve a sealing effect on the connection between the roller 1 and the drum 2 .

[0038] The following is a detailed description of the working principle of the steel-plastic composite roller.

[0039] like Figures 1 to 5As shown, the wear-resistant jacket 4 is sleeved from the side of the main body 21, and the position of the docking slot 43 is made to correspond to the position of the outer protruding horizontal bar 22, and then the wear-resistant layer 41 is pushed from the side to make the wear-resistant layer 41 move laterally along the outside of the main body 21, so that the wear-resistant layer 41 is completely covered on the outside of the main body 21, and then the outer chuck 51 is used to clamp it on the left and right sides of the main body 21, and the docking hole 52 is made to correspond to the fixing hole 23, and then the fixing bolt 53 is passed through the docking hole 52 and is threadedly connected to the inside of the fixing hole 23, and the outer chuck 51 is fixed to the outside of the main body 21, so that the outer chuck 51 is pressed against the wear-resistant layer 4 The position of the wear-resistant layer 41 is limited from the side to fix the wear-resistant layer 41. The wear-resistant outer sleeve 4 is located outside the main body 21 to improve the wear resistance and corrosion resistance. When the wear-resistant outer sleeve 4 is damaged, the wear-resistant outer sleeve 4 can be replaced separately by removing the fixing plate 5. A gap is left between the wear-resistant layer 41 and the main body 21, and a through hole 54 corresponding to the gap position is opened inside the outer chuck 51. The gap between the main body 21 and the wear-resistant layer 41 allows the internal heat to be dissipated to the outside. The heat dissipation fan provided on the conveyor accelerates the air flow rate, so that the air enters the gap to accelerate the heat dissipation.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
