Description

A belt deviation detection device

technical field

The utility model relates to a belt deviation detection device, which belongs to the field of belt conveying control.

Background technique

In the existing long-distance belt transmission equipment, due to problems such as installation or belt slippage, the belt will deviate. If the deviation distance is too large, it will damage the belt, damage the motor, and even pose a threat to personal safety. In order to avoid this situation, a detection method is added so that the belt can automatically detect and alarm when the belt deviates, reducing equipment damage and protecting personal safety.

Contents of the invention

The utility model provides a belt deviation detecting device, which is used to solve the problem of belt deviation.

The technical scheme of the utility model is: a belt deviation detection device, including a metal block to be detected 1, a proximity switch I2, a proximity switch II3, a transmission belt 4, an industrial computer system 5, an alarm light 6, and an alarm bell 7, for The proximity switch bracket 8 that fixes the proximity switch I2 and the proximity switch II3; the metal block 1 to be detected is respectively sensed by the proximity switch I2 and the proximity switch II3, and the induction signals of the proximity switch I2 and the proximity switch II3 are input to the industrial computer system 5 respectively, and run In the partial state, the industrial computer system 5 in the device sends an alarm signal to the alarm lamp 6 and the alarm bell 7 .

The proximity switch bracket 8 is a U-shaped structure.

The metal block 1 to be detected is in the shape of a sheet or a strip.

The sheet metal blocks 1 to be detected are symmetrically installed on the edge of the conveyor belt 4 at intervals.

The strip-shaped metal blocks 1 to be detected are installed below the conveyor belt 4 at intervals.

During use, when the belt 4 does not deviate, when the proximity switch Ⅰ2 and the proximity switch Ⅱ3 installed on the proximity switch bracket 8 detect the metal block 1 to be detected on the belt 4, if the signal is sent to the industrial computer system at the same time 5, then it can be judged as no deviation at this time.

In the actual operation of the equipment, if there is slipping or jamming, the belt will be unevenly stressed, which may cause deviation. At this time, the signal will appear symmetrically. The proximity switch I2 installed on the edge of the conveyor belt 4 first detects the metal block to be detected. 1, and the metal block 1 to be detected is detected after the proximity switch Ⅱ3, so that a time difference t is generated between the two detection signals. According to the belt transmission speed v, the belt deviation value L can be calculated, L=v×t, When L exceeds the alarm value, the industrial computer system 5 sends a signal alarm to the alarm lamp 6 and the alarm bell 7 to achieve the purpose of protecting equipment and personnel.

In addition, it should be noted that since the alarm signal is based on the time difference between the signals sent by the proximity switch Ⅰ2 and the proximity switch Ⅱ3, when the belt deviates seriously, the proximity switch Ⅰ2 and the proximity switch Ⅱ3 will also detect the signal from the asymmetric It turns out that the signal on the metal block 1 adjacent to the metal block 1 to be detected leads to misjudgment by the system, so when setting the alarm value L, L=S/2 can be used (wherein S is the two metal blocks to be detected before and after 1).

The beneficial effects of the utility model are: it solves the monitoring problem of the deviation of the belt conveyor, reduces the workload, improves the working life of the equipment, ensures the personal safety of personnel, and has the advantage of not requiring personnel to be on duty all the time.
