Technical Field

[0001] The present application relates to the field of belt conveyor equipment detection, and in particular to a deviation detection device. Background Art

[0002] Most deviation switches are of vertical roller type structure. Vertical roller deviation switches use the lateral displacement of the belt conveyor equipment when it deviates to touch the vertical roller and cause it to deflect. The deflection of the vertical roller drives the internal structural parts to trigger the micro switch inside the deviation switch, thereby outputting an alarm signal.

The enclosed belt conveyor equipment (such as belt conveyor, scraper conveyor, air cushion conveyor, etc.) has metal wall panels on the side walls, and the internal space is limited. The belt is close to the inner wall of the silo, and there is not enough space to install the vertical roller deviation switch. Therefore, the installation environment of the current vertical roller deviation switch is more restricted. Summary of the invention

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of this application. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict.

[0030] Belt conveyor is a kind of conveying equipment widely used in industrial production, logistics and transportation. During the operation of belt conveyor, the deviation of conveyor belt not only affects the quality of conveyed materials, but also may cause frequent shutdown of belt conveyor if the conveyor belt deviates frequently, thus affecting the life of belt conveyor. Therefore, deviation switch plays a vital role in belt conveyor. Deviation switch is mainly used to detect and prevent conveyor belt from deviating during operation, so as to ensure the safety and stability of conveying process.

[0031] Reference Figure 1 as well as Figure 3a , Figure 3b and Figure 3cThe present application provides a deviation detection device 100, which is used for a belt conveyor device 200, wherein the belt conveyor device includes a conveyor belt, and the deviation detection device 100 includes: a mounting component 101, a contact component 102, a transmission component 103, a spring component 104, and a sensing component; the mounting component 101 is used to mount the deviation detection device 100 on the belt conveyor device; the contact component 102 includes a roller component 1020 and a pressing component 1021, wherein, when the mounting component is used to When the deviation detection device 100 is installed on the belt conveyor equipment, the roller member 1020 is arranged corresponding to a part of the conveyor belt, and when the conveyor belt contacts the roller member 1020, the roller member 1020 can be deflected, and when the roller member 1020 deflects, a part of the extrusion member 1021 can be driven to rotate in a direction away from the conveyor belt; the transmission assembly 103 is arranged corresponding to the extrusion member 1021, and when the extrusion member 1021 is moved to the conveyor belt, the extrusion member 1021 is driven to rotate in a direction away from the conveyor belt. When rotating in a direction away from the conveyor belt, the transmission component 103 can move in a direction away from the conveyor belt; the spring component 104 is arranged corresponding to at least a part of the transmission component 103, and when the transmission component 103 moves in a direction away from the conveyor belt, the spring component 104 can provide the transmission component 103 with a force in the direction of the conveyor belt; the sensing component is arranged opposite to the transmission component 103, and the sensing component is located on a side away from the extrusion member 1021, and the sensing component is used to form a predetermined sensing range, wherein in an initial state, the transmission component 103 does not enter the sensing range; in a first-level deviation state, the conveyor belt contacts the roller member 1020, and when the roller member 1020 deflects and drives a part of the extrusion member 1021 to rotate in a direction away from the conveyor belt, the transmission component 103 moves in a direction away from the conveyor belt and enters the sensing range, and the transmission component 103 enters the sensing range to change the inductance value of the sensing component.

[0032] In this embodiment, the belt conveyor device includes a conveyor belt. The conveyor belt may be a belt, a rubber belt, a plastic belt, or a cloth belt, etc., and this application does not impose any specific restrictions on this, as long as the technical principle of this application can be realized. In this application, if there is no additional description, "belt" will be used as an example of a conveyor belt, "belt conveyor device" will be used as an example of a belt conveyor device, and "deviation switch" will be used as an example of a deviation detection device.

[0033] Refer to the following Figure 1 , Figure 4 as well as Figure 5a and Figure 5b, a deviation detection device 100 according to an embodiment of the present application is described.

[0034] The mounting assembly 101 is used to mount the deviation detection device 100 (i.e., deviation switch) on the belt conveyor. When the belt conveyor 200 is running, the shaft bearing in the shaft bearing seat 202 will drive the roller 203 on the lower side of the belt 201 to rotate. If the belt 201 deviates, it will start to deviate from the roller 203. Therefore, the deviation switch can be mounted on the side wall at a predetermined distance (e.g., the predetermined distance can be set to 1m or 3m) from the driving wheel or the driven wheel of the belt conveyor 200. The height of the roller member 1020 can be set to 100mm, and it can be mounted on a closed belt conveyor. During installation, the roller member 1020 faces the belt 201 (if it is a closed belt conveyor, the roller member 1020 is first installed on the side wall of the closed belt conveyor), is perpendicular to the belt 201 (at a 90-degree angle), and the belt 201 and the roller member 1020 maintain a certain distance (for example, the distance can be set to 0.5mm-10mm). In the initial state (refer to Figure 5a ), the transmission component 103 does not enter the sensing range; in the first deviation state, the belt 201 contacts the roller member 1020, and when the roller member 1020 deflects and drives a part of the extrusion member 1021 (i.e., the connecting rod 1021A) to rotate in the direction away from the belt 201, the transmission component 103 moves in the direction away from the belt 201 and enters the sensing range of the sensing component. The transmission component 103 enters the sensing range, causing the inductance value of the sensing component to change. At this time, the belt is in the first deviation state (refer to Figure 5b ).

[0035] In the initial state, the belt 201 does not deviate; or the belt 201 deviates by a small distance and has not yet touched the roller member 1020 of the deviation switch; or the belt 201 deviates by a small distance and although the belt 201 touches the roller member 1020 of the deviation switch 100, the roller member 1020 drives the extrusion member 1021 to move a small distance, so the transmission assembly 103 does not move. The initial state, the primary deviation state, etc. will be described below in conjunction with specific embodiments.

[0036] The mounting assembly 101 may be flat, L-shaped, U-shaped or cross-shaped, and may be installed on the belt conveyor 200 by means of screws, clips or expansion bolts. The present application does not impose any specific restrictions on the installation method of the mounting assembly 101, as long as the deviation switch 100 and the belt conveyor 200 can be fixedly installed.

[0037] The mounting assembly 101 may also include a gasket 114. For example, by adding a gasket 114 (such as a rubber gasket) between the deviation switch 100 and the belt conveyor 200, the vibration between the deviation switch 100 and the belt conveyor 200 can be reduced when the belt conveyor 200 is running, thereby better protecting the deviation switch 100. It can be understood that the above description of the mounting assembly 101 and its composition, installation method, etc. is only exemplary, and those skilled in the art can select the mounting assembly 101 according to actual needs, as long as the technical principles of the present application can be realized.

[0038] In this embodiment, the contact assembly 102 includes a roller component 1020 and an extrusion component 1021. The roller component 1020 includes: a sleeve cover 1020A, a retaining ring 1020B, a rotating shaft 1020C, a sleeve 1020D and a bearing 1020F. Because the sleeve cover 1020A is a sealing component of the roller component 1020, it is mainly used to prevent dust, water vapor and other impurities from entering the interior, thereby protecting the normal operation of the internal bearing 1020F and the rotating shaft 1020C. The material of the sleeve cover 1020A can be selected from metal or high-strength plastic, which can improve the sealing and wear resistance of the sleeve cover 1020A. The retaining ring 1020B is used to fix the bearing 1020F and the rotating shaft 1020C to prevent displacement during operation. The retaining ring 1020B is installed on the outer ring or inner ring of the bearing to ensure the stability and reliability of the bearing. The rotating shaft 1020C is one of the core components of the roller component 1020, which is used to connect the bearing 1020F and the sleeve 1020D to support the rotation of the entire roller component 1020. Therefore, the material of the rotating shaft 1020C can be selected from 45# steel, which has high mechanical strength and wear resistance, so that the running stability and service life of the roller component 1020 can be improved. The sleeve 1020D is used to protect the rotating shaft 1020C and the bearing 1020F, and at the same time plays a supporting and connecting role. The sleeve 1020D can be made of high-strength steel, so that the sleeve 1020D can have good corrosion resistance and wear resistance. The bearing 1020F is a key component of the roller component 1020, which is used to reduce the friction between the rotating shaft 1020C and the sleeve 1020D. The reliability of the roller component 1020 can be improved by designing and selecting materials for each component of the roller component 1020. The above description on the composition and material selection of the roller component 1020 is only exemplary, and those skilled in the art may select the composition and material of the roller component 1020 according to actual needs, as long as the technical principles of the present application can be implemented.

[0039] The extrusion member 1021 includes: a connecting rod 1021A, a retaining ring pin 1021B and a screw 1021C. The connecting rod 1021A is used to connect with the roller member 1020, the retaining ring pin 1021B is arranged inside at least a part of the extrusion member 1021, and the extrusion member 1021 can rotate around the retaining ring pin 1021B. In order to keep the extrusion member 1021 balanced when rotating, the retaining ring pin 1021B can be arranged at the center of the extrusion member 1021, and then the retaining ring pin 1021B is fixed by the screw 1021C, so that the retaining ring pin 1021B and the extrusion member 1021 can be ensured to remain stable when the extrusion member 1021 rotates. The above description of the composition of the extrusion member 1021 is only exemplary, and those skilled in the art can select the extrusion member 1021 according to actual needs, as long as the technical principle of the present application can be realized.

[0040] In this embodiment, the contact assembly 102 includes: the contact surface between the roller member 1020 and the pressing member 1021 is set as a meshing surface, and a toothed boss is provided on the meshing surface. Figure 3c The contact surface between the roller component 1020 and the connecting rod 1021A of the extrusion component 1021 is set as the meshing surface of the toothed boss. The roller component 1020 and the connecting rod 1021A can be fastened by screws. The angle of the roller component 1020 can be adjusted by adjusting the matching of the meshing surface. It can be compatible with different side wall distances of the belt conveyor equipment 200, thereby meeting more installation conditions.

[0041] In this embodiment, Figure 1 The roller member 1020 and the pressing member 1021 shown in FIG. 1 are arranged correspondingly. It can be understood that the arrangement of the contact assembly 102 and Figure 1 The examples are merely exemplary, and those skilled in the art may select the contact component 102 according to actual needs, as long as the technical principles of the present application can be implemented.

[0042] In this embodiment, the transmission assembly 103 is arranged corresponding to the extrusion member 1021, and when the extrusion member 1021 rotates in a direction away from the conveyor belt, the transmission assembly 103 can move in a direction away from the conveyor belt. The transmission assembly 103 is arranged corresponding to the extrusion member 1021. When the belt 201 deviates, the belt 201 contacts the roller member 1020. When the roller member 1020 deflects and drives a part of the extrusion member 1021 to rotate in a direction away from the belt 201 (that is, the connecting rod 1021A rotates in a direction away from the belt 201), the transmission assembly 103 moves in a direction away from the belt 201 and enters the sensing range of the sensing assembly. The transmission assembly 103 enters the sensing range to change the inductance value of the sensing assembly. In order to change the inductance value of the sensing assembly, the material of the transmission assembly 103 is metal. The above description of the transmission assembly 103 is only exemplary, and those skilled in the art can select the transmission assembly 103 according to actual needs, as long as the technical principle of the present application can be realized.

[0043] In this embodiment, the mounting assembly 101 includes: a limiter 112, which is arranged corresponding to the transmission assembly 103 and is used to limit the position of the transmission assembly 103. For example, the limiter 112 can limit the movement position of the transmission assembly 103 to prevent the transmission assembly 103 from exceeding a predetermined range of travel. If the limiter 112 is not provided, the transmission assembly 103 will move excessively and damage certain components inside the deviation switch 100. Therefore, the limiter 112 is provided corresponding to the transmission assembly 103.

[0044] In this embodiment, the spring assembly 104 is arranged corresponding to at least a part of the transmission assembly 103, and when the transmission assembly 103 moves in a direction away from the conveyor belt 201, the spring assembly 104 can provide the transmission assembly 103 with a force in the direction of the conveyor belt 201. The spring assembly 104 is used to reset the transmission assembly 103. For example, when the transmission assembly 103 is squeezed by the squeezing member 1021, the squeezing member 1021 moves in a direction away from the belt 201. At this time, the spring assembly 104 is compressed, thereby generating a force in the direction of the belt 201. When the belt 201 returns to normal, the roller assembly 1020 is free from the lateral pressure of the belt 201. At this time, the compressed spring assembly 104 can reset the squeezing member 1021 through the transmission assembly 103. The above arrangement of the spring assembly 104 is only exemplary, and those skilled in the art can select the spring assembly 104 according to actual needs, as long as the technical principle of the present application can be realized.

[0045] In this embodiment, the induction component is arranged opposite to the transmission component 103, and the induction component is located on the side away from the extrusion member 1021, and the induction component is used to form a predetermined induction range. For example: the induction component (such as the inductor 105 or the proximity switch 115) is arranged opposite to the transmission component 103, and the induction component is located on the side away from the extrusion member 1021. After the induction component is energized, a predetermined induction range (such as the induction range is set to 0.5mm-10mm) is formed, and a part of the extrusion member 1021 (i.e., the connecting rod 1021A) rotates away from the belt 201 while squeezing the transmission component 103 away from the belt 201, thereby entering the induction range of the induction component to change the inductance value of the induction component, and the belt 201 is in a first-level deviation state. The above selection of the induction component is only exemplary, and those skilled in the art can select the induction component according to actual needs, as long as the technical principles of the present application can be realized.

[0046] In this embodiment, in the secondary deviation state, the transmission component 103 enters the sensing range and stays in the sensing range for more than a predetermined time. In the secondary deviation state, the predetermined time can be set to when the transmission component 103 stays in the sensing range for more than 3 seconds. For example, when the transmission component 103 enters the sensing range 5mm-10mm and stays for more than 3 seconds, the belt 201 has a secondary deviation (refer to Figure 5b ).

[0047] In this embodiment, the deviation detection device 100 further includes: a status indicator light (not shown in the figure), and the status indicator light can display different colors for the initial state, the first-level deviation state, and the second-level deviation state. For example, the status indicator light can be set as an LED light of three colors: red, yellow, and green. In the initial state, the LED light displays green; in the first-level deviation state, the LED light displays yellow; in the second-level deviation state, the LED light displays red. The above setting of the status indicator light is only exemplary, and those skilled in the art can select the status indicator light according to actual needs, as long as the technical principle of the present application can be implemented.

[0048] In this embodiment, the deviation detection device 100 further includes: a circuit board assembly 106, and the circuit board assembly 106 is used to supply power to the inductor 105 and the status indicator light. For example, the circuit board assembly 106 is installed in the deviation switch, and the circuit board assembly 106 supplies power to the inductor 105 and the status indicator light.

[0049] In this embodiment, the deviation detection device 100 further includes: a cover 107, and the cover 107 is arranged outside at least a part of the deviation detection device 100. Because the roller component 1020 of the deviation switch needs to contact the belt 201, the roller component 1020 is exposed, and the other components of the deviation switch 100 are arranged in the cover 107, which can better protect the deviation switch 100. In addition, the working environment of the deviation switch 100 is dusty and humid. In order to prevent dust and moisture inside the deviation switch, the cover 107 can be made of stainless steel.

[0050] In this embodiment, because there are gaps in the mounting assembly 101 and the transmission assembly 103, and the working environment of the deviation switch is dusty and humid, in order to prevent the interior of the deviation switch 100 from dust and moisture, the mounting assembly 101 can be sealed and protected by a seal 111, and the transmission assembly 103 can be sealed and protected by an O-ring 1031. In order to further improve the sealing of the deviation switch and prevent the components from getting damp, epoxy resin can be potted in the deviation switch, because epoxy resin has good electrical insulation, chemical resistance and high temperature resistance, so that the deviation switch can be better protected. When potting, the epoxy resin can use low molecular liquid bisphenol A type epoxy resin, such as E-54, E-51, E-44, E-42. These epoxy resins have low viscosity and high epoxy value, and are suitable for potting.

[0051] In this embodiment, the deviation detection device 100 further includes: a cable 110, and the cable 110 is used to connect the deviation detection device 100 to an external power source. For example, one end of the cable 110 is connected to a connection terminal of the deviation switch 100 through a terminal, and the other end of the cable 110 is connected to an external power source, thereby providing power for the deviation switch 100.

[0052] In this embodiment, the deviation detection device 100 further includes: a wire protection tube sleeve 109, which is arranged outside the cable 110 and connected to the cover 107. For example, the wire protection tube sleeve 109 is arranged outside the cable 110 and connected to the cover 107, so that the cable can be prevented from being damaged (such as scratches, wear and extrusion) during installation and use, thereby extending the service life of the cable.

[0053] In this embodiment, the deviation detection device 100 also includes a light guide 108, which is arranged opposite to the status indicator light and is used to guide light to the status indicator light. The light guide 108 can transmit light from one light source to another position, so the light of different colors (red, yellow, green) emitted by the LED lamp can be transmitted to the surface of the cover 107 of the deviation switch through the light guide 108, so that the staff can quickly understand the operating status of the belt conveyor equipment. In addition, in this embodiment, the light guide gasket 116 is used to seal the light guide 108, which can reduce light loss and improve the lighting effect.

[0054] Refer to the following Figure 2 as well as Figure 3a , Figure 3b and Figure 3c A deviation detection device 100 according to another embodiment of the present application is described. Figure 2 The deviation detection device 100 shown is similar to the one described above with reference to Figure 1 The main differences between the described deviation detection devices are: Figure 2 The sensor component of the deviation detection device 100 shown is replaced by a proximity switch 115 Figure 1 The inductor 105 and the circuit board assembly 106, that is, the transmission assembly 103 moves away from the belt 201 and enters the sensing range of the proximity switch 115, triggering the proximity switch 115 to output a signal, thereby realizing the detection of the deviation of the belt 201.

[0055] The triggering principle of the deviation detection device 100 in this embodiment is similar to Figure 1 The deviation detection device 100 described is consistent with the above, and the technical concept has been described in detail in the above embodiments, which will not be repeated here.

[0056] Reference Figure 4 as well as Figure 5a and Figure 5b , the assembly of the deviation detection device and the belt conveyor equipment and the operation process of the deviation detection device are explained.

[0057] When the belt conveyor 200 is running, the shaft bearing in the shaft bearing seat 202 will drive the roller 203 on the lower side of the belt 201 to rotate. If the belt 201 deviates, it will start to deviate from the roller 203. Therefore, the deviation switch can be installed on the side wall (204) at a predetermined distance (such as the predetermined distance can be set to 1m or 3m) from the driving wheel or the driven wheel of the belt conveyor 200. When installed, the roller member 1020 of the contact component 102 faces the belt 201 and is perpendicular to the belt 201 (at an angle of 90 degrees). When the belt is not deviated (i.e., in the initial state), Figure 5aAs shown, the belt 201 and the roller member 1020 maintain a certain distance (for example, the distance can be set to 1mm), and the transmission component 103 does not enter the sensing range at this time, and the status indicator light is green. In the first-level deviation state, the belt 201 contacts the roller member 1020. When the roller member 1020 deflects and drives a part of the extrusion member 1021 (i.e., the connecting rod 1021A) to rotate in the direction away from the belt 201, the transmission component 103 moves away from the belt 201 and enters the sensing range of the sensing component. The transmission component 103 enters the sensing range, causing the inductance value of the sensing component to change. At this time, the belt is in the first-level deviation state, and the status indicator light is yellow. When the belt 201 deviates, it will deviate laterally, causing the belt 201 to contact the roller member 1020. At this time, if the belt 201 continues to deviate laterally, the transmission component 103 enters the sensing range of 5mm-10mm and stays for more than 3 seconds. At this time, the belt is in the second-level deviation state, and the status indicator light is red.
