Embodiment

[0044] A conveyor belt 2 with a width of 800mm, a belt speed of 1.25m / s, a length of 28m, a diameter of the driving drum 1 of 630mm, the material to be transported is iron concentrate, and the conveying capacity is 400t / h. According to the calculation, the tension of the conveyor belt is 17.28KN , the tension force is 6.31KN; the bearing plate is 100mm high and 250mm wide;

[0045] Based on F=P*S and rated tension F 0 When it is 6.31KN, the rated pressure in the air chamber can be obtained as 0.2524MPa, so the range of pressure transmitter 8-4 is 0.6MPa; 4 Calculate the tension F of the conveyor belt 2 in real time from the online detection data 1 and the rated value F of the specific tension force in the design of the conveyor belt 2 0 It is 6.31KN, the upper limit of the interval is 6.3731KN and the lower limit of the interval is 6.2469KN:

[0046] When F 1 p 6.2469KN, open the intake solenoid valve 7-7, inflate the air chamber, the pressure in the air chamber increases,...

Abstract

The invention belongs to the technical field of industrial conveyor belt installation and detection, and particularly relates to a conveyor belt tensioning force detection and control device which ischaracterized by comprising a conveyor belt mechanism, a pushing mechanism connected with the conveyor belt mechanism and a control mechanism connected with the pushing mechanism. The pushing mechanism comprises an air cylinder, a stress plate arranged in the air cylinder, a push-pull column with one end being fixedly connected with the stressed plate and the other end being fixedly connected witha moving trolley, an air source connecting pipe communicating with the air cylinder, an air inlet electromagnetic valve, a check valve , an exhaust pipe communicating with the air cylinder, and an exhaust electromagnetic valve; and the control mechanism comprises a sampling pipe communicating with the air cylinder, a pressure transmitter, a blow-off pipe, and a control unit connected with the pressure transmitter. According to the conveyor belt tensioning force detection and control device provided by the invention, through an air source, the air inlet electromagnetic valve, the pressure transmitter, the exhaust electromagnetic valve and the control unit, online detection and control over the tensioning force of a conveyor belt are achieved, so that the service life of the conveyor belt is prolonged, and the occurrence of the phenomenon of lost rotation or slipping of the conveyor belt is avoided.

Description

technical field [0001] The invention belongs to the technical field of installation and detection of industrial conveyor belts, and in particular relates to a detection and control device for tension force of a conveyor belt. Background technique [0002] With the continuous improvement of smelting technology and production capacity, more and more conveyor belts are used. At the same time, with the continuous improvement of automation level, the requirements for conveyor belt operation detection are also getting higher and higher, especially in the aspect of conveyor belt tension. Because Excessive tension will cause the tension of the conveyor belt to be too high, which will shorten the service life of the conveyor belt and seriously cause the conveyor belt to break; too small tension will cause the tension of the conveyor belt to be too small, and the friction between the drive roller and the conveyor belt will decrease, resulting in lost rotation. Even severely skidded. ...
