Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1 to 5 and 8, a belt conveyor includes a frame 6, a driving roller 2, a driven roller 3, a conveying belt 5 and a motor 1, wherein the conveying belt 5 is connected between the driving roller 2 and the driven roller 3 in a surrounding manner, and the motor 1 drives the driving roller 2 to rotate and finally drives the conveying belt 5 to move. For real-time automatic deviation rectifying conveyor belt, the inventor proposes:

An adjusting roller 4 is additionally arranged between the driving roller and the driven roller, one end of the adjusting roller 4 is fixedly connected to the rack through a bearing seat 402, and the other end of the adjusting roller 4 is slidably mounted on the rack through the bearing seat; in order to realize the sliding installation of the bearing seat, a pneumatic or electric device can be adopted for driving. Taking pneumatics as an example, the main body of the adjusting roller 4 is a roller body 401; the device is also provided with a hinged seat 403, an air cylinder 404 and a sliding seat 405, wherein the air cylinder 404 is arranged on the rack 6 through the hinged seat 403, an expansion link of the air cylinder is fixedly connected with the sliding seat 405, and the sliding seat 405 is slidably arranged on the rack; one end of the roller body is fixedly connected to the frame through a bearing seat, and the other end of the roller body is arranged on the sliding seat 405 through the bearing seat; the bearing seat is preferably a spherical bearing;

Limit switch 7 is installed to aforementioned conveyor belt's both sides, and limit switch 7 real-time supervision conveyor belt's skew situation, when conveyor belt skew reaches limit switch settlement position, the slip of the other end of limit switch 7 control regulating roll, if: the cylinder is driven to make the contraction rod of the cylinder do the stretching/contracting movement. At the moment, the other end of the adjusting roller performs horizontal swinging arm sliding movement by taking the fixed connection point O of the adjusting roller as a center.

As shown in FIG. 6, when the adjusting roller tensions the conveying belt, the conveying belt exerts a pressure on the adjusting roller, and the conveying belt moves to generate a friction force between the adjusting roller and the conveying belt. When the central axis of the adjusting roller is changed from O-AO to O-A1, FN can be decomposed into two component forces of F1 and F2, and the reaction force of the component force F1 drives the conveying belt to move towards the direction of A1, so that the offset effect is generated. Similarly, when the central axis of the regulating roller is rotated to the position O-A2 from the position O-AO, the conveying belt moves towards the direction O, and the opposite deviation regulation is generated.

The control circuit is shown in fig. 11. In the figure: m denotes a normally open contact of a contactor that controls a main motor of the belt conveyor, QT denotes an emergency stop button switch, Q1 denotes a left limit switch, Q2 denotes a right limit switch, M1 denotes a left contactor, M2 denotes a right contactor, Y1 denotes a left solenoid valve, and Y2 denotes a right solenoid valve. Taking the left limit switch circuit as an example, the conveying belt touches the left limit switch Q1, the left limit switch Q1 is started, the left contactor M1 works, and the left electromagnetic valve Y1 is controlled. In the same way, the right solenoid valve Y2 is controlled.

The air path is as shown in fig. 12. When left contactor M1 is active, it controls left solenoid valve Y1, allowing compressed air to enter cylinder 404 through pneumatic triplet 8, solenoid valve Y1. Solenoid valve Y1 is preferably a two-position, five-way solenoid valve 9, with compressed air entering and exiting the cylinder 404 through a cylinder speed control valve 10.

During normal use, when conveyor belt off tracking, when conveyor belt touched one side limit switch, as shown in fig. 11, 12, limit switch transmitted the signal for the contactor, and the contactor passes through solenoid valve control cylinder, and the telescopic link drive dancer rools's of cylinder other end is slided. At the moment, the adjusting roller slides as a horizontal swing arm, and the conveying belt moves towards the required direction under the action of friction force until the adjusting roller touches a limit switch on the other side and then returns. The conveying belt can swing back and forth between the two limit switches, and real-time automatic deviation correction is realized.

Example two

As an improvement of the first embodiment of the present invention, as shown in fig. 4-5 and 7-9, a sliding seat 405, which includes a guiding strip 4051, an upper connecting plate 4052, a side standing plate 4053, a lower connecting plate 4054, an adjusting bolt 4056, a baffle 4058 and a slider 4059, wherein:

The upper connecting plate 4052, the lower connecting plate 4054 and the side station plate 4053 are fixedly connected into an integral piece which can be fixed on the frame by a fixing bolt 4055;

The guide strip 4051 is fixed on the upper connecting plate 4052 by welding, or fixed on the lower connecting plate 4054 by welding, or fixed on the upper connecting plate 4052 and the lower connecting plate 4054 by welding;

The bolt bracket 4057 is fixed on the lower connecting plate 4054 or the frame, and the baffle 4058 is installed on the bolt bracket 4057 through the adjusting bolt 4056;

And a sliding block 4059 is arranged between the baffle plates 4058, the sliding block 4059 is in sliding fit with the guide strip 4051, and the baffle plates limit the sliding area of the sliding block, so that the safety is ensured and the reliability is improved.

The other end of the dancer roll is mounted by a bearing block which is mounted on a slider 4059.

In order to test the specific effect, the inventor carries out related tests, and the test data are as follows:

Test subjects: AHDD-PD240/4 flat belt conveyor.

The operation condition of the original flat belt conveyor is adopted: the conveying belt runs off seriously only for two days, and cannot be used normally.

Adopt the utility model discloses an operational aspect: the conveying belt can slightly deviate between the limit switches on the two sides repeatedly, the conveying requirement is met, manual supervision is not needed, and automatic deviation correction can be achieved.
