Detailed Description
The present utility model will be described in further detail with reference to examples.
A conveyor belt longitudinal tearing detection device is shown in figure 1, and comprises a receiving net 1, a swinging frame 2, a fixed seat 3, a proximity switch 4, an adjusting counterweight 5 and an induction piece 6; the fixed seat 3 is positioned on the ground, the middle part of the swinging frame 2 is rotationally connected with the fixed seat 3, the upper part of the swinging frame is hinged with the material receiving net 1, and the two sides of the material receiving net 1 extend towards the width direction of the conveying belt; the induction piece 6 is positioned on the swinging frame 2, and the proximity switch 4 is arranged on one side of the fixed seat 3 and is matched with the induction piece 6; the adjusting counterweight 5 is sleeved at the bottom of the swinging frame 2.
Preferably, the material receiving net 1 is a steel wire net with 5 x 5mm mesh size, fixing brackets are arranged around the steel wire net, and the fixing brackets are hinged with the upper part of the swinging frame 2. The fixed support is square steel pipe.
The material receiving net 1 is designed into a steel wire net structure, so that daily dust falls on the upper side and the storage quantity is greatly reduced, and false signals caused by dust are prevented.
The receiving net 1 is arranged at the position of the belt conveyor, which is close to the receiving chute, the size of the receiving net 1 is slightly larger than 50mm along each side of the width direction of the conveying belt, and the receiving net is designed to be 500mm long along the length direction of the conveying belt. The specification of the receiving net 1 can be 6×6mm, and the specification can be adjusted according to the property of the transported materials, wherein the adjustment is based on the fact that most of the materials can be just caught by the receiving net 1 once the materials fall down through the split, so that only a very small amount of fine powder can pass through the meshes.
The swing frame 2 is also provided with an extension plate 7, the extension plate 7 is positioned between the upper part and the middle part of the swing frame 2, the extension plate 7 is a rectangular bulge vertically arranged on the swing frame 2, and the extension plate 7 is caught by a hand under special conditions so as to avoid the hand from directly touching the swing frame 2. The swinging frame 2 is a square steel pipe.
The adjusting counterweight 5 is a counterweight, a hole for sleeving the swinging frame 2 is formed in the middle of the counterweight, a groove for containing magnets is formed in the bottom of the adjusting counterweight 5, and thus counterweights with different numbers can be overlapped, and the counterweight effect is improved.
Correspondingly, the swinging frame 2 is of a parallelogram structure, the adjusting counterweight 5 is positioned on one side edge of the swinging frame 2, and the proximity switch 4 is close to the swinging frame 2 on the other side edge. As shown in fig. 1, the adjusting weight 5 is located on the right side of the swing frame 2, and the proximity switch 4 is located near the swing frame 2 on the left side.
The upper edge of the parallelogram mechanism of the swinging frame 2 is connected with the receiving net 1 through a pin, the middle part of the parallelogram mechanism is connected with the upright posts on two sides of the fixed seat 3 through a pin, the parallelogram mechanism can rotate downwards by taking the middle pin as the axial direction after receiving the pressure of the upper edge, in order to balance the pressure, an adjusting counterweight 5 used for balancing is arranged at the lower part of the mechanism, under normal conditions, the upward moment generated by the adjusting counterweight 5 on the parallelogram mechanism is slightly larger than the downward moment generated by the dead weight of the receiving net 1 on the parallelogram mechanism, so the receiving net 1 is kept at a position of about 100mm under a conveyor belt, when the conveyor belt is longitudinally torn, the material falls onto the receiving net 1 through a split, the balance can be broken, when the downward moment generated by the gravity of the material on the mechanism is larger than the upward moment generated by the adjusting counterweight 5, the mechanism moves downwards, a sensing piece 6 is driven to be close to a proximity switch 4 to send an electric signal, and an electric appliance control system is instructed to act, so that the conveyor stops running.
As shown in fig. 1, the outer side of the adjusting weight 5 may be further provided with a circular arc handle, which is used as a part of the adjusting weight 5, so that the weight of the adjusting weight 5 is increased, the running smoothness of the device is increased, and the manual adjustment or leveling is facilitated.
The proximity switch 4 is arranged on the fixed seat 3 through the mounting seat and is positioned on one side of the swinging frame 2, and the proximity switch 4 is an electromagnetic proximity switch.
The operation principle of the device is that when the conveyer belt is longitudinally torn by foreign matters, the materials on the upper part of the conveyer belt fall to the lower layer through a split opening, the device is arranged on the lower part of the conveyer belt, which is close to a chute, the material receiving net 1 of the device can collect the fallen materials, as the swinging frame 2 of the device is designed into a parallelogram mechanism, the material receiving net 1 can swing up and down, when the weight of the materials collected by the material receiving net 1 exceeds a certain value, the material receiving net 1 moves downwards, the induction piece 6 is close to the proximity switch 4, the proximity switch 4 converts the signals into electric signals, and the electric signals are transmitted to an electric appliance control system of the equipment through a cable, and a shutdown command is sent to prevent the tearing condition from expanding.
The installation position of the device is as follows: the device is suitable for being arranged at a place where the belt conveyor is suitable to be close to the front of the material receiving chute along the direction of conveying materials, and a plurality of sets of devices can be arranged in sequence to increase the detection probability. The accident that the conveyer belt takes place vertical tearing generally appears in the place of receiving the material chute, and after the conveyer belt was vertically torn, the material can be followed the breach and spill the material downwards, and the device connect the material net 1 to receive the material after, receive the action of gravity, connect the material net to remove downwards, drive swing frame 2 rotation, trigger electromagnetic proximity switch after, send the signal of telecommunication instruction conveyer belt shut down to avoid the expansion of accident.
