Abstract

The utility model relates to a belt-crossbreaking monitoring device for a belt conveyer. The utility model comprises a microcomputer monitoring alarm, sensors, and ferromagnetic bodies. The ferromagnetic bodies which are used as the test points are buried at both sides of each junction of the conveyer belt and approaching to the edges of the belt. The upper sides of trusses which are arranged at both sides of the conveyer belt are respectively provided with the sensor which is used for monitoring the speed of the belt and the sensor which is used for monitoring the elongation indicator of the junctions of the belt. The sensors are connected with an interface corresponding to the microcomputer monitoring alarm through a signal transmission line. The utility model can carry out the continuous detection for both sides of the junction of the conveyer belt, can carry out the random measurement for the running speed of the belt, and can carry out the display and the record printing for the elongation indicator and the current speed of each junction of the conveyer belt on the microcomputer. The utility model thoroughly avoids the malignant accidents generated by the cross breaking of the conveyer belt in the prior art.

Description

The horizontal broken belt monitoring device of belt conveyer

The utility model relates to the horizontal broken belt monitoring device of a kind of belt conveyer, belongs to system controlled by computer automatic continuous monitoring technology.

At present, produce and use the accident of unit in order to avoid the load-transfer device cross break to be caused as far as possible of belt conveyer, the way that generally adopts artificial naked eyes to monitor, like this, though wasted stock production time and manpower and materials, effect is not good.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and a kind of horizontal broken belt monitoring device of belt conveyer that adopts electronic sensor to combine with the microcomputer-based intelligent monitoring is provided.

The purpose of this utility model is achieved in that this device comprises the micro computer monitoring annunciator, sensor, both sides in each joint of load-transfer device, and close belt edge is embedded with the kicker magnet as test point, the sensor V of monitoring belt speed and the sensor L that elongation should be held by monitoring belt connector place are housed respectively on a certain side truss of load-transfer device both sides, two sensors lay respectively at both sides, belt connector place, on the opposite side truss, and face the sensor R that this end elongation of monitoring is equipped with at the belt connector place, described sensor is connected with micro computer monitoring annunciator corresponding interface by its signal transmssion line respectively.

Device that the utility model is given and monitoring method thereof, can be to the bilateral continuous detecting of carrying out of conveying band joint, can carry out random measurement to its running velocity, can be on the microcomputerized control instrument elongation, the present speed value of each joint of load-transfer device be shown, resolution to the measuring accuracy of elongation can reach 1mm, if equipped chopping machine, also can be regularly, at random the physical quantitys such as current operational factor of load-transfer device are carried out multinomial print record.

The explanation of accompanying drawing drawing:

Fig. 1 is a running condition structural representation of the present utility model.

Fig. 2 is a Hall element profile scheme drawing of the present utility model.

Fig. 3 is a micro computer monitoring annunciator schematic appearance of the present utility model.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model is made of the sensor V (4) of monitoring belt speed, sensor L (2) and R (8), kicker magnet (3) and the micro computer monitoring annunciator (9) of monitoring belt connector place elongation.The kicker magnet (3) that is embedded in each belt (5) both sides, joint and close belt (5) edge is right for 3-4, described sensor V (4), L (2) and R (8) are loaded on respectively on the truss (1) and (6) of belt conveyor (5) both sides, wherein sensor V (4) and L (2) lay respectively at belt (5) both sides, joint, sensor R (8) faces belt (5) joint, and sensor L (2), V (4), R (8) are connected with micro computer monitoring annunciator (9) the corresponding interface by its signal transmssion line (7) respectively.Sensor of the present utility model all adopts Hall element, its profile as shown in Figure 2, housing (10) sidepiece has signal transmssion line (7) jack, at housing (10) middle part, housing (10) is fixed on corresponding truss (1) or (6) with bolt (12) by its base plate test sensitivity volume (13) with epoxy encapsulation.Micro computer monitoring annunciator of the present utility model (9) as shown in Figure 3, have on the front panel of its housing (14) and show with charactron (15), indication color lamp (16), keyboard (17) and switch (18), corresponding signal transmssion line jack, printer interface are set, relay interface and spare interface etc. on the rear panel.

Principle of work of the present utility model that is monitoring method as shown in Figure 1, the both sides, belt connector place of load-transfer device (5) are buried kicker magnet (3) E as test point respectively underground ₁, E ₂, E ₃, E ₄And E _{1 '}, E _{2 '}, E _{3 '}, E _{4 '}When load-transfer device (5) is pressed the operation of method shown in the figure, each test point just can be caught a detection signal through sensor V, the arbitrary sensor of L, R, and pass to microcomputer prison annunciator (9), load-transfer device (5) is generally rubber, being in operation to produce elastic deformation, the test point E of (in the elastic range) load-transfer device (5) one sides when normal operation ₁, E ₂Apart from the point and E ₃, E ₄Distance should be a definite value, when load-transfer device (5) joint produces plastic deformation and promptly extends, E then ₁, E ₂Between distance and E ₂, E ₃Between distance fixed than the relation will change, can draw conveying band joint place development length through micro computer monitoring annunciator (9) analyzing and processing, in conjunction with corresponding preset parameter, can reach extension, laterally broken belt carries out pre-alarm, the test point E of load-transfer device (5) opposite side to load-transfer device (5) _{1 '}, E _{2 '}, E _{3 '}, E _{4 '}Also like this, micro computer monitoring annunciator of the present utility model (9) can be designed to have multidimensional functions such as the intelligence identification, normalization of horizontal broken belt continuous monitoring to belt conveyer, speed continuous monitoring, side pilot.
