Detailed Description
The utility model is further illustrated with reference to the following figures and examples.
As shown in fig. 1 and 2, the belt conveyor turning mechanism of the present invention includes a frame 1, an upper carrier roller frame 2 and a lower carrier roller frame 3, wherein the upper carrier roller frame 2 and the lower carrier roller frame 3 are vertically disposed on the frame 1, the upper carrier roller frame 2 and the lower carrier roller frame 3 are respectively provided with a carrier roller set 4, and the carrier roller set 4 on the upper carrier roller frame 2 forms a groove-shaped structure through the upper carrier roller frame 2. The carrier roller group 4 on the upper carrier roller frame 2 is used for supporting a belt 5 for carrying goods, and the carrier roller group 4 on the lower carrier roller frame 3 is used for supporting a belt 5 which is empty. In order to ensure the anti-deviation effect and convenient online adjustment, the upper supporting roller frame 2 is hinged with the frame 1 through a hinge shaft 7, the hinge shaft 7 is arranged in the middle of the upper supporting roller frame 2, the upper supporting roller frame 2 can rotate towards the inner side of a curve 8 through the hinge shaft 7, and one side of the frame 1 is provided with an adjusting mechanism 6 for driving the upper supporting roller frame 2 to rotate around the hinge shaft 7 so as to control the rotating angle of the upper supporting roller frame 2 towards the inner side of the curve.
The turning mechanism of the belt conveyor can drive the upper supporting roller frame 2 to rotate around the hinge shaft 7 through the adjusting mechanism 6, so that the upper supporting roller frame 2 is controlled to rotate towards the inner side of the curve, and thus, the upper supporting roller frame 2 can be adjusted at a proper position to better offset the centrifugal force generated when the belt turns. According to the turning mechanism, the hinge shaft 7 is arranged in the middle of the upper supporting roller frame 2, the adjusting mechanism 6 is arranged on one side of the rack 1, the hinge shaft 7 can bear most of the weight of the upper supporting roller frame 2, and the adjusting mechanism 6 only needs to provide smaller overturning moment, so that the rotation angle of the upper supporting roller frame 2 towards the inner side of a curve can be conveniently adjusted on line through the matching of the hinge shaft 7 and the adjusting mechanism 6. When the belt turns to, a plurality of belt conveyor turning mechanisms need to be arranged at the bent corner to change the direction, the turning mechanism enables the hinge shaft 7 to be arranged in the middle of the upper supporting roller frame 2, and the belt is more gently transited when passing through the turning mechanism.
In order to further prevent the belt 5 from deviating, the outer side of the upper supporting roller frame 2 is provided with a deviation-preventing vertical roller 21 for preventing the belt from sliding to the outer side of the curve. The deviation-preventing vertical roller 21 is rotationally connected with the upper supporting roller frame 2. When the centrifugal force of the belt is too large, the deviation-preventing vertical roller 21 can prevent the belt from sliding outwards.
The number of the carrier rollers on the carrier roller group 4 can be 2, 3, … …; the groove-shaped structure formed by the carrier roller group 4 can be U-shaped, V-shaped, horn-shaped and the like. The carrier roller group 4 on the upper carrier roller frame 2 comprises three carrier rollers 41, and the three carrier rollers 41 are arranged in a horn shape.

The adjusting mechanism 6 can be a cylinder, a hydraulic cylinder, an electric push rod and the like, and the adjusting mechanism 6 is a scissor jack, one end of the scissor jack is fixedly connected with the rack 1, and the other end of the scissor jack is hinged with the upper supporting roller frame 2.
In order to prevent the idle return belt from deviating, the carrier roller group 4 on the lower carrier roller frame 3 also forms a groove-shaped structure through the lower carrier roller frame 3. The channel structure may also be U-shaped, V-shaped, flared, etc. The carrier roller group 4 on the lower carrier roller frame 3 comprises two carrier rollers 41, and the two carrier rollers 41 are discharged into a V shape. Because empty belt that returns need not transport goods, the bearing roller group 4 on the lower roller frame 3 adopts V type groove type structure, and it prevents that the off tracking effect is better. Preferably, the lower idler frame 3 is disposed to be inclined toward the inside of the curve.
The inclination of the lower idler frame 3 can also be arranged in an adjustable manner in order to facilitate the adjustment of the inclination of the lower idler frame 3 as a function of the actual situation. Because the gravity of the returned belt is light, the inclination of the lower carrier roller frame 3 can be adjusted directly by hands, and of course, the inclination of the lower carrier roller frame 3 can also be adjusted by a mechanism. In order to reduce the equipment cost, preferably, a plurality of adjusting holes 11 distributed along the height direction are respectively arranged on two sides of the frame 1, and two ends of the lower carrier roller frame 3 are respectively matched with the adjusting holes 11 on two sides of the frame 1 to adjust the inclination angle of the lower carrier roller frame 3 towards the inner side of the curve.
