Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyor pipes, and in particular to a belt conveyor pipe deflection torque detection system and method. Background Art

[0002] The tubular conveyor (hereinafter referred to as the pipe conveyor) was developed by Japan's Bridgestone Corporation in 1964. It is a new type of machine developed on the basis of the ordinary trough belt conveyor. Its conveyor belt is still a flat belt, but the rollers are properly arranged in its loaded branch section, so that the conveyor belt, which was originally trough-shaped at the loading point, is rolled up into a round tube. The edges of the conveyor belt on both sides overlap each other, and the material is wrapped in the tube for transportation until it approaches the unloading point, and the conveyor belt is unfolded again and can be flattened and wound around the head roller. The pipe conveyor may deviate and twist during operation, which is specifically manifested in the belt overlap position deflecting from the top to the sides or even below, causing abnormal wear of the conveyor belt and rollers, material spillage, and even conveyor belt flipping, tearing and other major equipment failures, with economic losses ranging from hundreds of thousands to millions.

[0003] The existing belt conveyor detection device can only detect the twisting direction of the belt conveyor belt, but cannot quantify the twisting angle, which results in the inability to determine the adjustment force when adjusting the belt conveyor belt. Summary of the invention

[0004] The invention provides a system and method for detecting the deflection torque of a belt conveyor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A connecting plate, fixed on the linear slider;

[0011] Rollers are used to support the load-bearing belt and are installed on the connecting plate through roller brackets;

[0012] The pressure sensor is installed on the liftable platform through a mounting plate. The pressure sensor is installed between the mounting plate and the connecting plate and is in contact with the connecting plate.

[0013] Furthermore, the liftable platform comprises a lift platform base, a jack is mounted on the lift platform base, the jack is controlled by a motor, and the upper end of the jack is connected to the lift platform upper seat.

[0014] Furthermore, a sliding pin is installed at the upper end of the lifting platform base, a sleeve is installed at the lower side of the lifting platform upper seat, and the sliding pin is arranged in the sleeve.

[0015] Furthermore, the jack is a scissor jack.

[0016] Furthermore, two linear guide rails are provided, and the two linear guide rails are arranged in parallel on the lifting platform upper seat of the lifting platform.

[0017] Furthermore, each of the linear guide rails is provided with two linear sliders, and the linear sliders on the same side of the two linear guide rails are connected via a connecting plate.

[0018] Furthermore, each connecting plate is equipped with a roller bracket.

[0019] The present invention has the following advantages: the present invention drives the roller to move horizontally through the belt conveyor, and detects the deflection angle through the pressure sensor, thereby feeding back to the deviation adjustment system, making the deviation adjustment more convenient and quick.

The linear sliders 5 are mounted on the linear guide rails 4; the connecting plate 6 is fixed on the linear sliders 5; a roller bracket 7 is mounted on each connecting plate 6. The roller 8 is used to support the load-bearing section belt 1, and is mounted on the connecting plate 6 through the roller bracket 7; the pressure sensor 13 is mounted on the liftable platform through the mounting plate, and the pressure sensor 13 is installed between the mounting plate and the connecting plate 6, and is in contact with the connecting plate 6.
