Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connection, in particular to a lower parallel roller lifting lug of a belt conveyor. Background Art

[0002] Belt conveyors are the main equipment for material transportation in industrial and mining enterprises. When the belt is running, it often deviates. However, the existing lifting lugs are basically in a broken line shape, and the structure is too simple. The distance between the lower roller and the lifting lug of the belt conveyor is very close. When the belt deviates during heavy-load operation, the belt and the lifting lug will scrape and collide, causing damage to the belt. When the lifting lug is subjected to excessive lateral force, it is easy to deform. In addition, there is no locking device between the roller shaft and the lifting lug. When the belt deviates during heavy-load operation, the roller will fall off. Utility Model Content

[0003] The technical problem to be solved by the utility model is to reduce the scraping phenomenon between the belt and the lifting lug, the roller falling off, and prevent the belt from running off when it is under heavy load, and provide a lower parallel roller lifting lug for a belt conveyor.

[0004] In view of the above technical problems, the technical solution of the utility model is a parallel roller lifting ear under a belt conveyor, comprising a fixed bracket, the fixed bracket comprising a bracket vertical surface, a bracket bottom surface, and a bracket top surface, one end of the bracket bottom surface is fixedly connected to one end of the bracket top surface through the bracket vertical surface, and a transverse reinforcement plate, the transverse reinforcement plate is fixedly connected to the upper surface of the bracket bottom surface, and the transverse reinforcement plate is provided with a roller shaft mounting hole on the end face of the fixed bracket in the opening direction.

[0005] Specifically, the transverse reinforcing plate has the same area as the bottom surface of the bracket, and they are overlapped and fixedly connected.

[0006] Specifically, the transverse reinforcement plate is fixedly connected to the bottom surface of the bracket by welding.

[0007] Specifically, the parallel roller lifting lug also includes a longitudinal reinforcement plate, which is vertically connected to the bracket.

[0008] The inner surface of the surface is fixedly connected, and its upper and lower ends respectively abut against the lower surface of the top surface of the bracket and the upper surface of the transverse reinforcement plate.

[0009] Specifically, the longitudinal reinforcing plate is fixedly connected to the bracket facade by welding.

[0010] Specifically, the upper end surface of the transverse reinforcing plate is an arc surface.

[0011] Specifically, the roller shaft mounting hole has a reinforcing pin key.

[0012] Specifically, the fixing bracket and the transverse reinforcing plate are made of stainless steel.

[0013] Compared with the prior art lifting lug, the fixed bracket has a lateral extension distance, so the utility model has the beneficial effect of preventing the belt from running off and preventing the belt from scratching against the lifting lug, which may cause the belt to be damaged and the lifting lug to be deformed. Due to the arrangement of the longitudinal reinforcing plate, the roller can be effectively prevented from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Unless otherwise defined, technical or scientific terms used herein shall have the common meanings understood by a person having ordinary skills in the field to which this application belongs.

[0022] The specific implementation methods of the utility model are fully and detailedly described below in conjunction with the accompanying drawings.

[0023] like Figure 1, as shown in Figure 2, a belt conveyor lower parallel roller ear includes a fixed bracket 2, the fixed bracket 2 includes a bracket vertical surface 2a, a bracket bottom surface 2b, and a bracket top surface 2c, one end of the bracket bottom surface 2b is fixedly connected to one end of the bracket top surface 2c through the bracket vertical surface 2a, and a transverse reinforcing plate 3, the transverse reinforcing plate 3 is fixedly connected to the upper surface of the bracket bottom surface 2b, and the transverse reinforcing plate 3 has a roller shaft mounting hole on the end surface of the fixed bracket 2 in the opening direction, which cooperates with the roller 1 shaft. Because there is a lateral extension distance, the distance between the roller end surface and the vertical surface of the ear is increased, which avoids the scraping of the belt and the vertical surface of the roller ear when the belt deviates slightly. When the belt deviates seriously, the vertical surface of the ear can limit the belt from further deviating. The bracket top surface 2c is fixedly connected to the belt frame 5 with bolts.

[0024] Specifically, the transverse reinforcing plate 3 is equal in area to the bottom surface 2b of the bracket, and they are overlapped and fixedly connected, which can achieve a better reinforcing effect.

[0025] Specifically, the transverse reinforcing plate 3 is fixedly connected to the bottom surface 2b of the bracket by welding, which has a better reinforcing effect from the perspective of the connection method.

[0026] like Figure 3 As shown, specifically, the parallel roller lifting ear also includes a longitudinal reinforcing plate 4, which is fixedly connected to the inner surface 2a of the bracket facade, and its upper and lower ends respectively abut against the lower surface of the bracket top surface 2c and the upper surface of the transverse reinforcing plate 3. The longitudinal reinforcing plate 4 on the inner side of the bracket has sufficient force strength to limit the longitudinal movement of the roller 1 axis and prevent the roller 1 from falling off.

[0027] Specifically, the longitudinal reinforcing plate 4 is fixedly connected to the bracket facade 2a by welding, which has a better reinforcing effect from the perspective of the connection method.

[0028] Specifically, the upper end surface of the transverse reinforcing plate 3 is an arc surface. In the case that the roller bearing is damaged, the belt comes into contact with the round top surface of the transverse reinforcing plate 3. Since the top surface is a smooth arc surface, the belt will not be scratched in a short time.

[0029] Specifically, the end face of the longitudinal reinforcing plate 4 in the opening direction of the fixed bracket 2 is an arc surface. When the belt deviates seriously, the longitudinal reinforcing plate 4 on the inner side of the vertical surface of the ear contacts the belt, and the belt contacts the top surface of the arc. Because its top surface is a smooth arc surface, the belt will not be scratched in a short time.

[0030] Specifically, the roller shaft mounting hole is provided with a reinforcing pin key, which can further prevent the longitudinal movement of the roller shaft 1 and prevent the roller 1 from falling off.

[0031] Specifically, the fixed bracket 2 and the transverse reinforcing plate 3 are made of stainless steel, which can improve the strength and corrosion resistance of the bracket and extend the service life of the bracket.

[0032] Specifically, the longitudinal reinforcing plate 4 is made of stainless steel, which can improve the strength and corrosion resistance of the bracket and extend the service life of the bracket.

[0033] The above description is merely an exemplary embodiment of the present application and is not intended to limit the protection scope of the present application. The protection scope of the present application is determined by the appended claims.
