Description

Movable tape longitudinal tearing monitoring device

Technical Field

The utility model belongs to the technical field of rubber belt conveyors, and particularly relates to a movable rubber belt longitudinal tearing monitoring device.

Background

Belt conveyors, also known as belt conveyors, are widely used in various industries. In general, the rubber belt of the rubber belt conveyor does not have a longitudinal tearing phenomenon in normal operation, and the rubber belt is possibly scratched or torn only when the rubber belt is seriously deviated or external sharp objects such as steel plates, iron blocks, large gangue and the like are poked into the rubber belt.

In the underground coal transportation process, the working condition is complex, so that the situation that the adhesive tape is torn is more. For example, constructors carelessly leave hard objects such as a drill bit, I-steel and the like for construction near the mouth of a chute; the components on the coal feeding equipment and the coal blocking device fall off; the omission of the anchor rods and the like on the conveyor in the coal mining process can possibly cause the tearing of the adhesive tape.

In order to reduce the loss as far as possible, the adhesive tape longitudinal tearing early warning device is generally arranged at the tail of the machine, so that when the hidden danger of longitudinal tearing is generated, the machine can be stopped in time, and further expansion of the longitudinal tearing is prevented. Because the mine is continuously tunneled in the exploitation process of coal, the rubber belt conveyor also needs to be disassembled and assembled or the unit body is supplemented, so that the conveyor can be timely extended to the exploitation position. When the rubber belt conveyor is used for disassembling the machine body or supplementing the machine body of the unit, the longitudinal tearing early warning device needs to be disassembled and then reinstalled at the tail of the machine. When the assembly and disassembly are carried out each time, a plurality of people are needed to cooperate with the operation, the consumption time is long, and the production time is influenced.

Description of the embodiments

In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings that are needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present utility model, and other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.

Referring to fig. 1 to 3, a movable device 10 for monitoring longitudinal tearing of an adhesive tape 90 includes a plurality of travelling wheels 20, a travelling frame 30, a deviation sensor 402 assembly 40, a roller frame 50, an adhesive tape 90 piercing sensor 60, and a controller 70, wherein the travelling wheels 20 are located at two sides of the bottom of the travelling frame 30, the deviation sensor 402 assembly 40 is located at two sides of the upper end of the travelling frame 30, the roller frame 50 is located between the deviation sensor 402 assemblies 40 at two sides, the roller frame 50 is used for supporting the adhesive tape 90, the running resistance of the adhesive tape 90 is reduced, the adhesive tape 90 piercing sensor 60 is located between the roller frame 50 and the adhesive tape 90, the deviation sensor 402 assembly 40, the adhesive tape 90 piercing sensor 60 are electrically connected with the controller 70, and the controller 70 performs early warning according to the received sensor signals.

The longitudinal tearing of the tape 90 is mainly caused by both the deviation and the puncture of the tape 90. However, the deviation and the puncture of the adhesive tape 90 do not necessarily lead to the longitudinal tearing of the adhesive tape 90, and the utility model can provide early warning for the longitudinal tearing of the adhesive tape 90. Specifically, the off-tracking sensor 402 of the present utility model monitors whether the tape 90 is off-tracking. Since the direction of the deviation of the adhesive tape 90 is uncertain, deviation sensors 402 are provided on both sides of the carrier roller frame 50. When the adhesive tape 90 is deviated, the deviation sensor 402 detects and generates an electric signal to be transmitted to the controller 70, and the controller 70 sends out an early warning. Still further, the off-tracking sensor 402 may be a pressure sensor. In general, the greater the degree of deflection, the greater the pressure experienced by the deflection sensor 402. If the deviation sensor 402 receives a relatively small pressure, possibly with a scratch of coal or the like, the controller 70 may check the operation of the adhesive tape 90 in the field by converting the pressure signal into a numerical value and displaying the numerical value on the monitoring device. If the deflection sensor 402 is subjected to a very high pressure, this indicates that the deflection is severe, and there is a high likelihood that the device will fail and that the tape 90 will likely be torn longitudinally. In this case, the controller 70 controls the belt 90 conveyor to stop to prevent greater losses. To distinguish the degree of deviation from normal production, the controller 70 is provided with a low pressure reference value and a high pressure reference value. When the pressure detected by the off tracking sensor 402 is less than the low pressure reference, a monitoring person is alerted to inspect the tape 90 in the field. When the pressure detected by the off-tracking sensor 402 is greater than the high pressure reference, the conveyor of the adhesive tape 90 is controlled to stop to prevent the expansion of the longitudinal tear effect of the adhesive tape 90. In another preferred embodiment, the deviation sensor 402 is an infrared signal sensor. An infrared emitter and a receiver are respectively arranged above and below the adhesive tape 90. The adhesive tape 90 does not interfere with the infrared signal sensor during normal operation, and the infrared receiver is always capable of receiving an infrared signal. When the adhesive tape 90 is deflected, it interferes with the infrared signal sensor, and the infrared signal is not continuously received by the infrared receiver. This also means that the controller 70 receives no signal, and at this point the controller 70 controls the conveyor of the tape 90 to stop to prevent the tape 90 from tearing longitudinally.

The adhesive tape 90 pierces the sensor 60 between the adhesive tape 90 and the roller housing 50, and in a preferred embodiment is a pressure sensor, preferably a pressure sensitive sensor, having a length equal to the width of the bottom of the adhesive tape 90. When the conveyor is in normal operation, the pressure-sensitive sensor is only subjected to the pressure of the material above the adhesive tape 90, and the pressure signal is stable. When the adhesive tape 90 is pierced, the pressure applied to the pressure-sensitive sensor is suddenly increased by piercing members such as steel plates, iron blocks, and iron bars, and the controller 70 controls the conveyor of the adhesive tape 90 to stop so as to prevent the longitudinal tearing of the adhesive tape 90 or the longitudinal tearing of the adhesive tape 90.

The utility model integrates the deviation sensor 402 and the adhesive tape 90 penetration sensor 60 on the walking frame 30, and can timely find hidden trouble of longitudinal tearing of the adhesive tape 90. When the conveyor with the adhesive tape 90 operates normally, the travelling wheel 20 below the travelling frame 30 is acted by the material on the adhesive tape 90, and the pressure between the travelling wheel and the conveyor frame is high, so that the travelling wheel cannot move on the guide rail of the conveyor frame. When the conveyor is to be disassembled, the traveling frame 30 is also easy to move because no material exists above the adhesive tape 90. Because the machine tail is generally assembled only by one section, the walking frame 30 only needs a certain distance, and the machine is very convenient and does not need to be disassembled and assembled.

Since the conveyor frame is also formed by one section of conveying units, the two sections of conveying units are connected through the E-shaped pins 801, and the end parts of the E-shaped pins 801 protrude out of the guide rails. The travelling carriage 30 is therefore laborious to ride over the E-shaped pins 801, the travelling carriage 20 being provided with grooves 201 to facilitate passage through the conveyor frame 80 on which the E-shaped pins 801 are mounted.

In a preferred embodiment, the off-tracking sensor 402 assembly 40 includes a sensor support 401 and an off-tracking sensor 402, the upper end of the sensor support 401 is fixedly connected with the off-tracking sensor 402, the sensor support 401 includes a fixing base 4011 and a swinging rod 4012, the lower end of the fixing base 4011 is fixedly connected with the walking frame 30, the upper end of the fixing base 4011 is hinged with the swinging rod 4012, a clamping groove is further provided at the upper end of the fixing base 4011, so that the swinging rod 4012 can incline inwards, and the upper end of the swinging rod 4012 is fixedly connected with the off-tracking sensor 402.

Under normal conditions, the swing rod 4012 is supported by the clamping groove and can only incline inwards by a certain angle, when the deviation degree of the adhesive tape 90 is large, the adhesive tape 90 presses the swing rod 4012, and when the swing rod 4012 is pressed to the outside by the gravity center, the swing rod 4012 is inclined outwards under the action of gravity. In this manner, the off-tracking sensor 402 may be protected from continued compression, causing damage to the sensor.

The downhole operation environment is severe, and the travelling wheel 20 and the track are easily blocked by coal ash, so in a preferred embodiment, the dustproof slots 301 are arranged on two sides of the travelling frame 30, the dustproof slots 301 are -shaped, the bottoms of the dustproof slots 301 are open, the travelling wheel 20 is positioned in the dustproof slots 301, and through holes are arranged on two sides of the dustproof slots 301, so that the rotary shafts of the travelling wheel 20 are sleeved with the dustproof slots 301. Thus, the dust-proof groove 301 keeps the coal ash out, and prevents the road wheels 20 and the track from being blocked.

The foregoing disclosure is illustrative of the preferred embodiments of the present utility model, and is not to be construed as limiting the scope of the utility model, as it is understood by those skilled in the art that all or part of the above-described embodiments may be practiced with equivalents thereof, which fall within the scope of the utility model as defined by the appended claims.
