Technical Field

The utility model relates to the technical field of belt conveying, in particular to a belt conveying device.

Background

The belt transmission consists of a driving wheel, a driven wheel and an annular belt tightly sleeved on the two wheels. Due to the belt tension, a pressing force is generated at the contact portion of the belt with the pulley. When the driving wheel runs, the belt is driven to run by the action of friction force, and the driven wheel is driven to run by the running belt. In long-time operation, the belt can be loosened, so that uneven internal stress distribution of the belt is caused, and the chance of belt deviation is increased. Severe vibration of the belt drive during belt operation can also cause the belt to run off. When the deviated belt runs, abnormal friction occurs between the belt and the support, so that the edge of the belt is worn, the service life of the belt is influenced, and meanwhile, abnormal damage to main parts of equipment can be possibly caused. When the belt deviates to a certain extent, the belt can trigger the deviation prevention emergency stop device, so that the operation system is stopped, and the production process is influenced.

In view of this, the present utility model has been made.

Referring to fig. 1 to 4, an embodiment of the present application provides a belt conveying apparatus, including: the device comprises a bracket 1, a driving wheel 2, a driven wheel 3, a belt 4 and a plurality of limiting pieces 5. The driving wheel 2 is connected with the bracket 1. The driven wheel 3 is rotatably connected to the bracket 1. The belt 4 is sleeved on the driving wheel 2 and the driven wheel 3. Each limiting piece 5 is connected to the bracket 1, each limiting piece 5 is located at two sides of the belt 4 along the width direction, the limiting piece 5 has a smooth surface, and in the state that the belt 4 is deviated, one side edge of the belt 4 along the width direction can contact with the limiting piece 5.

When the belt 4 runs, the belt 4 is displaced and deviated in the width direction of the belt 4, and the displaced belt 4 contacts the surface of the stopper 5. At this time, the stopper 5 may exert a reverse force on the belt 4, thereby urging the belt 4 to return to its original position. The two sides of the belt on the support can be provided with a plurality of limiting pieces, each limiting piece on the same side is sequentially arranged at intervals along the length direction of the belt, and when the belt 4 runs, no matter the belt 4 shifts along any side of the width direction of the belt 4, the belt 4 can be promoted to return to the original position. The limiting piece 5 has a smooth surface, so that friction force when the limiting piece 5 is contacted with the belt 4 can be reduced, and abrasion to the belt 4 is reduced.

In one embodiment, as shown in fig. 3, the limiting member 5 has a cylindrical shape, the limiting member 5 has a smooth cylindrical outer wall 521, and the central axis of the limiting member 5 is perpendicular to the belt 4. In a state where the belt 4 is deviated in the horizontal direction, one side edge of the belt 4 in the width direction is in contact with the cylindrical outer wall surface 521 of the stopper 5. The cylindrical outer wall 521 of the stopper 5 exerts a reverse force on the belt 4 to urge the belt 4 back to its original position. While a smooth cylindrical outer wall 521 also reduces wear on the belt 4.

In one embodiment, the limiting member 5 has a central post 51 and a sleeve 52 rotatably sleeved on the central post 51, and the sleeve 52 has the cylindrical outer wall 521. Since the sleeve 52 of the central post 51 may rotate along the central post 51 of the limiting member 5, when the belt 4 contacts the surface of the limiting member 5, the belt 4 and the limiting member 5 maintain a relatively stationary state in the length direction of the belt 4, which further reduces the friction between the belt 4 and the surface of the limiting member 5.

In one embodiment, as shown in fig. 3 and 4, a bearing 53 is provided between the center post 51 and the sleeve 52. If the bearing 53 is not provided, a relatively large friction is generated by sliding friction between the sleeve 52 and the center post 51 during rotation. The design of the bearing 53, the direct sliding friction between the sleeve 52 and the central column 51 is converted into the running fit by the bearing, the running resistance is obviously reduced, and the sleeve 52 is smoother when rotating. The deviated belt contacts the surface of the sleeve 52, and the sleeve 52 rotates around the central post 51 under the action of friction force, so that the belt 4 and the sleeve 52 keep a relative static state, friction between the belt 4 and the sleeve 52 is reduced, and abrasion of the belt 4 is reduced.

In one embodiment, the bracket 1 is provided with a plurality of upper arc-shaped supporting parts 11 and a plurality of lower horizontal supporting parts 12. Each upper arc-shaped supporting part 11 is arranged at intervals in the feeding direction, and each lower horizontal supporting part 12 is arranged at intervals in the feeding direction. The belt 4 has an upper belt section 41 and a lower belt section 42 on both sides of the line connecting the drive pulley 2 and the driven pulley 3. The upper belt section 41 is supported on the upper arc-shaped supporting portion 11, and the upper belt section 41 is formed with a concave cavity, so that concrete is convenient to transport on the belt 4, and concrete is prevented from falling down on the support 1 or around the support 1 along two sides of the belt 4 in the transportation process. The lower belt section 42 is supported by the lower horizontal support 12. The upper arc-shaped supporting part 11 is generally composed of three rotating rods, one rotating rod is positioned in the middle and is horizontally arranged, the other two rotating rods are respectively arranged on two sides of the middle rotating rod, and the two rotating wheels are obliquely arranged. The lower horizontal support 12 is typically a rotatable roller and the rotatable wheel is disposed horizontally. The rotary sticks are rotatably arranged, so that friction resistance with the belt is reduced.

It should be noted that, the cooperation of the upper arc-shaped supporting portion 11, the lower horizontal supporting portion 12 and the belt 4 is a mature prior art, and the literature data is more published, and the specific structure of the cooperation of the upper arc-shaped supporting portion 11, the lower horizontal supporting portion 12 and the belt 4 is not limited, and the upper arc-shaped supporting portion 11, the lower horizontal supporting portion 12 and the belt 4 on the market are suitable for the present application.

In one embodiment, each of the stoppers 5 is located on both sides of the lower belt segment 42 in the width direction. The lower belt section 42 is supported on the lower horizontal support 12 so that the lower belt section 42 is straight. When the lower belt segment 42 is displaced along the belt width direction, the limiting member 5 generates a reverse acting force on the lower belt segment 42, so as to urge the lower belt segment 42 to return to the original position. The upper belt section 41 is supported by the upper arc-shaped supporting portion 11, so the upper belt section 41 is in a concave shape of a circular arc. If each of the stoppers 5 is located at both sides of the upper belt section 41 in the width direction, when the upper belt section 41 is displaced in the belt width direction, the displaced upper belt section 41 contacts the surface of the stopper 5, and the stopper 5 still generates a reverse force to the upper belt section 41, but the upper belt section 41 further deepens the circular arc-shaped recess by the reaction force, and cannot return the displaced upper belt section 41 to its original position. Therefore, it is more reasonable that each of the stoppers 5 is disposed at both sides of the lower belt section 42 in the width direction.

In one embodiment, the bracket 1 comprises two side frames 13, the belt 4 is positioned between the two side frames 13, and the limiting member 5 is mounted on the side frames 13. The side frames 13 support the belt 4. The side frames 13 are mature prior art, the literature is more published, the specific structure of the side frames 13 is not limited in this application, and various side frames 13 are suitable for this application in the market.

In one embodiment, a cross beam 14 is connected between the two side frames 13, and the limiting member 5 is mounted on the cross beam 14. The cross member 14 is connected to the side frame 13, and is indirectly attached to the side frame 13 in correspondence with the stopper 5. The cross beam 14 is connected between the two side frames 13, so that the connection between the two side frames 13 and the cross beam 14 is more stable and is not easy to shift. Further guarantee the accuracy of locating part 5 position.

In one embodiment, the cross beam 14 is welded with a horizontal connecting plate 6, and the horizontal connecting plate 6 is a metal plate. The limiting piece 5 is vertically connected with the horizontal connecting plate 6. The space between the cross beam 14 and the side frame 13 is small, which is not beneficial to the installation of the limiting piece 5. The horizontal connecting plate 6 is welded on the cross beam 14, the horizontal connecting plate 6 extends out of the cross beam 14 along the width direction of the cross beam 14, the installation space of the limiting piece 5 is increased, and the limiting piece 5 is conveniently vertically installed on the horizontal connecting plate 6 and fixed.

In one embodiment, the horizontal connecting plate 6 is provided with a connecting hole 61, the limiting member 5 is supported on the upper surface of the horizontal connecting plate 6, the limiting member 5 is provided with a connecting groove 511, and the bolt 7 is connected to the connecting groove 511 of the limiting member 5 by passing through the connecting hole 61 from one side of the lower surface of the horizontal connecting plate 6. The center column 51 of the limiting piece 5 is fixed on the horizontal connecting plate 6 by the bolt 7, the limiting piece 5 fixed by the bolt 7 is firmer, and looseness of the limiting piece 5 relative to the horizontal connecting plate 6 can be avoided.

In one embodiment, a plurality of connection holes 61 are provided in the horizontal connection plate 6. The connecting holes 61 are sequentially spaced apart in a direction perpendicular to the traveling direction of the belt 4. The plurality of connecting holes 61 may be designed, and the limiting member 5 may be selectively installed at different positions of the horizontal connecting plate 6, so that the distance between the limiting member 5 and the belt 4 may be different. When the stopper 5 is mounted, the most appropriate attachment hole 61 may be selected according to the distance between the belt 4 and the side frame 13 and the distance by which the belt 4 is displaced in the width direction of the belt 4, so that the stopper 5 is mounted.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present utility model without departing from the scope of the utility model.
