Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a belt conveyor monitoring device.

[0025] This utility model provides, for example Figures 1-3 The belt conveyor monitoring device shown includes a monitoring frame 1 and two symmetrically arranged monitoring rollers 2, both of which are rubber rollers. The monitoring frame 1 is U-shaped, and a base plate 17 is fixed at both ends of the bottom. A movable wheel 18 is fixed at the four corners of the bottom of each base plate 17. A strip-shaped hole is opened at the top of the monitoring frame 1, and an adjustment mechanism is provided in the strip-shaped hole. Two symmetrically arranged sliding plates 3 are provided through the adjustment mechanism. The adjustment mechanism includes a bidirectional screw 13, which is rotatably disposed in the strip-shaped hole. The two sliding plates 3 are slidably disposed in the strip-shaped hole and are threadedly engaged with the rod wall of the bidirectional screw 13. A connecting rod 4 is fixedly disposed at the bottom of the sliding plate 3, and an operation box 5 is fixedly disposed at the bottom of the connecting rod 4. An elastic telescopic rod 6 is fixedly disposed on the inner wall of the operation box 5, and a support block 7 is fixedly disposed through the elastic telescopic rod 6. A vertical rod 8 is fixedly disposed at the bottom of the support block 7. The monitoring roller 2 is rotatably engaged with the vertical rod 8.

[0026] A pull plate 9 is fixedly provided on the top of the support block 7. The pull plate 9 is an L-shaped pull plate. A first energized contact 10 is fixedly provided on the inner wall of the pull plate 9. A second energized contact 11 is fixedly provided on the inner wall of the operation box 5. The first energized contact 10 and the second energized contact 11 are configured to cooperate with each other. An alarm 12 is fixedly provided on the top of the operation box 5. The alarm 12 is electrically connected with the first energized contact 10 and the second energized contact 11.

[0027] In order to drive the adjustment mechanism to operate stably, such as Figures 1-2 As shown, a motor 14 is fixedly installed on the upper back side of the monitoring frame 1. The output shaft of the motor 14 passes through a strip hole and is fixedly provided with a drive bevel gear 15. A transmission bevel gear 16 is fixedly sleeved on the rod wall of the bidirectional screw 13. The drive bevel gear 15 and the transmission bevel gear 16 are configured to cooperate.

[0028] Working principle: first, according to the belt width of the belt conveyor to be monitored, adjust the distance between the two monitoring rollers 2, start the motor 14 on the back side of the monitoring frame 1 upper end, the motor 14 output shaft drives the driving bevel gear 15 to rotate, the driving bevel gear 15 is engaged with the transmission bevel gear 16 fixed on the wall of the bidirectional screw 13, and then drives the bidirectional screw 13 to rotate in the strip hole at the top of the monitoring frame 1, since the two sliding plates 3 are slidingly arranged in the strip hole and are threadedly connected with the wall of the bidirectional screw 13, when the bidirectional screw 13 rotates, it will drive the two sliding plates 3 to move towards or away from each other along the strip hole, the sliding plates 3 drive the operation box 5, the vertical rod 8 and the monitoring roller 2 to move synchronously through the connecting rod 4 at the bottom, until the two monitoring rollers 2 correspond to the two sides of the belt respectively, meet the monitoring requirement of the belt width, then turn off the motor 14;

[0029] Then, by means of the moving wheels 18 at the bottom of the bottom plates 17 at both ends of the monitoring frame 1, the whole device is moved to the side of the belt conveyor, so that the belt is between the two monitoring rollers 2, and the monitoring rollers 2 are in contact with the side of the belt, when the belt conveyor is running, the belt drive will drive the monitoring roller 2 to rotate around the vertical rod, at this time, the elastic expansion rod 6 in the operation box 5 is in a natural expansion state, the first power supply contact 10 in the inner wall of the pull plate 9 at the top of the supporting block 7 is separated from the second power supply contact 11 in the inner wall of the operation box 5, the alarm 12 is not powered on, and no alarm is given;

[0030] If the belt deviates during operation, the deviated belt will extrude the corresponding monitoring roller 2 to one side, the monitoring roller 2 pushes the supporting block 7 to move towards the inside of the operation box 5 through the vertical rod 8, the supporting block 7 compresses the elastic expansion rod 6 at the same time, and drives the pull plate 9 and the first power supply contact 10 to move synchronously, when the deviation of the belt reaches the set threshold, the first power supply contact 10 contacts the second power supply contact 11, so that the circuit in which the alarm 12 is located is conducted, the alarm 12 is started and gives an alarm, reminding the staff to handle the belt deviation problem in time, avoiding the expansion of the fault, after the staff adjusts the belt to the normal position, the extrusion force of the belt on the monitoring roller 2 disappears, the elastic expansion rod 6 resets, drives the supporting block 7, the pull plate 9 and the first power supply contact 10 to return to the initial position, the first power supply contact 10 is separated from the second power supply contact 11, the alarm 12 stops alarming, and the device returns to the normal monitoring state.

[0031] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above description and drawings are illustrative in nature, and should not be construed as limiting the scope of protection of the claims of the present application.
