Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to an automatic correction device for belt conveyor misalignment in coal mines. Background Technology

[0002] With the continuous development of technology, the use of various energy sources in life has increased, and some clean energy sources have gradually increased. However, some special industries still use thermal energy, which increases the demand for coal. Coal mines also play a significant role in industrial production. When mining coal, conveyor structures are used to transport the coal and ensure its stable transport. Conveyor belts are usually used for this purpose.

[0003] Belt conveyors often experience belt misalignment due to long belt running distances, uneven material distribution at unloading points, and uneven road surfaces. Manual adjustment is time-consuming and labor-intensive, and even with the installation of anti-misalignment idlers in certain sections, the desired effect is not achieved. Currently available automatic belt misalignment correction devices vary in quality and have limited adaptability. Therefore, there is a need for an automatic belt misalignment correction device that is easy to manage and maintain, ensuring the safe operation of the belt conveyor and reducing the labor intensity of workers during maintenance. Utility Model Content

[0004] This utility model relates to an automatic correction device for belt conveyor misalignment in coal mines. An inner frame assembly is directly installed inside the conveyor assembly. A trigger assembly installed on the inner frame assembly can contact the conveyor belt of the conveyor assembly. When the conveyor belt deviates, the trigger assembly will be triggered, causing the inner end of the trigger assembly to drive the transmission assembly of the inner frame assembly. At this time, the transmission assembly contacts and drives the lifting assembly, thereby causing the transmission assembly to drive the lifting assembly. The lifting assembly will then rise to the corresponding position, thus calibrating the conveyor belt.

[0005] This utility model provides an automatic correction device for belt conveyor misalignment in coal mines, specifically including: a conveying assembly; an inner frame assembly is installed at both ends of the conveying assembly, and triggering assemblies are installed on both sides of the inner frame assembly. The triggering assemblies are in contact with the conveying assembly. A transmission assembly is installed on the inner frame assembly, and the triggering assemblies are connected to the transmission assembly. A lifting assembly is added at the triggering assembly position of the inner frame assembly, and the transmission assembly is connected to the lifting assembly. A tension spring is added at the tail end of the transmission assembly on the inner frame assembly, and an auxiliary roller is installed on the lifting assembly.

[0006] The main support of the conveying assembly has conveying rollers rotatably mounted at both ends, and a conveyor belt is wound between the two sets of conveying rollers. The side of the main support has a slotted structure.

[0007] The inner support of the inner frame assembly is mounted on the conveying assembly. The inner support has two sets of sliding groove structures. The front sides of the inner support are set as extension frames, which are perpendicular to the inner support. An outer frame is installed at the rear of the inner support, and a tension spring is installed on the outer frame.

[0008] The trigger frame of the trigger assembly is hinged to the outside of the expansion frame of the inner frame assembly. A transmission rod is rotatably mounted on the trigger frame. The transmission rod is shaped like an hourglass. A contact wheel is set at the other end of the trigger frame. A groove structure is set at the end of the contact wheel.

[0009] The drive rod of the transmission component is configured as a long rod with an outward protrusion. The outward protrusion is connected to the trigger component. The driven shaft of the transmission component is rotatably mounted on the extension frame of the inner frame component. The drive rod and the driven shaft are driven by a gear and rack mechanism.

[0010] The sliding block of the lifting component is slidably installed on the extension frame of the inner frame component. The bottom of the sliding block is connected to the driven shaft of the transmission component. The support frame of the lifting component is hingedly installed on the inner frame component. A support plate is connected between the bottom of the support frame and the sliding block. An auxiliary roller is rotatably installed on the support frame.

[0011] The lifting and triggering components installed on the inner frame assembly are both set in two symmetrical groups, and the inner frame assembly on the conveyor assembly is set in two symmetrical groups with the center of the circle. Each inner frame assembly is set at the head of the conveyor belt near the conveyor assembly.

[0012] This utility model provides an automatic correction device for belt conveyor misalignment in coal mines, which has the following beneficial effects:

[0013] In this invention, when the conveyor belt of the conveyor assembly shifts, it typically appears at the head. Therefore, an inner frame assembly is installed near the head of the conveyor assembly. Trigger components are installed at both ends of the inner frame assembly. When the conveyor belt shifts outward, it contacts the trigger components, driving them. Meanwhile, the inner end of the outer frame contacts the transmission component at the inner frame assembly, enabling the trigger components to drive the transmission components. Simultaneously, the transmission components contact the lifting components of the inner frame assembly, allowing them to transmit power. At this point, the lifting components raise the auxiliary rollers at a certain angle, squeezing the conveyor belt inward and correcting it. A tension spring is installed at the tail of the transmission component to assist in resetting it.

[0014] In addition, extension frames are directly installed at both ends of the inner bracket, and the extension frames are perpendicular to the inner bracket. This allows for easy installation of the triggering component and the transmission component at the extension frames. The two sets of sliding groove structures of the inner bracket ensure the stable sliding installation of the transmission component within the inner bracket. Tension springs are added to the outer bracket of the inner bracket, allowing each tension spring to connect with the transmission component and reset the transmission component.

[0015] Furthermore, the trigger frame is hinged, allowing it to swing flexibly. The transmission rod of the trigger frame is hourglass-shaped, enabling it to better contact the edge of the conveyor belt on the conveyor assembly. When the conveyor belt deviates, it will directly contact the transmission rod, thus driving the trigger frame. At this point, the contact wheel at the trigger frame swings, and the groove structure on the contact wheel drives the transmission assembly, achieving a stable transmission effect between the trigger assembly and the transmission assembly.

[0016] Furthermore, the outer protrusion is first connected to the trigger component, enabling the trigger component to slide and drive the transmission component. At this time, the drive rod drives the driven shaft through the gear and rack mechanism, realizing the rotation of the driven shaft and driving the lifting component. This completes the stable transmission of the lifting component by the transmission component. First, the transmission between the driven shaft and the sliding block adopts a threaded transmission method, enabling the transmission component to stably transmit the lifting component. After the sliding block slides, it can lift the support frame through the support plate, realizing the angular swing of the support frame. After the auxiliary roller is lifted to a certain angle, the tension of the conveyor belt is increased and reset by the auxiliary roller, achieving the correction effect of the auxiliary roller on the conveyor belt.

[0017] In addition, since the conveyor belt usually deviates at the head, the inner frame assembly is installed at the head of the conveyor belt on the conveyor assembly. The lifting assembly and triggering assembly on the inner frame assembly are set in two symmetrical sets to achieve a stable and automatic correction effect from both ends of the conveyor belt.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] Example 1: Please refer to Figures 1 to 6 :

[0037] This utility model proposes an automatic correction device for belt conveyor misalignment in coal mines, comprising: a conveying component 1; an inner frame component 2 installed at both ends of the conveying component 1, a trigger component 3 installed at both sides of the inner frame component 2, the trigger component 3 being in contact with the conveying component 1, a transmission component 4 installed on the inner frame component 2, the trigger component 3 being connected to the transmission component 4, a lifting component 5 installed at the trigger component 3 of the inner frame component 2, the transmission component 4 being connected to the lifting component 5, a tension spring 6 installed at the tail of the transmission component 4 of the inner frame component 2, and an auxiliary roller 7 installed on the lifting component 5.

[0038] Among them, such as Figure 1 Figure 2 As shown, conveying rollers 103 are rotatably mounted on both ends of the main support 101 of the conveying assembly 1, and a conveyor belt 102 is wound between the two sets of conveying rollers 103. The side of the main support 101 is provided with a slotted structure.

[0039] Among them, such as Figure 3 Figure 6 As shown, the inner support 201 of the inner frame assembly 2 is mounted on the conveying assembly 1. The inner support 201 has two sets of sliding groove structures. The front two sides of the inner support 201 are set as extension frames 202, which are perpendicular to the inner support 201. An outer frame 203 is installed at the rear of the inner support 201, and a tension spring 6 is installed on the outer frame 203. The extension frames 202 are directly set at both ends of the inner support 201, and the extension frames 202 are perpendicular to the inner support 201. This allows for easy installation of the trigger assembly 3 and the transmission assembly 4 at the extension frames 202. The two sets of sliding groove structures of the inner support 201 ensure the stable sliding installation of the transmission assembly 4 in the inner frame assembly 2. The tension spring 6 is added to the outer frame 203 of the inner support 201, so that the tension spring 6 can be connected to the transmission assembly 4, thereby resetting the transmission assembly 4.

[0040] Among them, such as Figure 3 Figure 6As shown, the trigger frame 301 of the trigger assembly 3 is hingedly installed on the outside of the extension frame 202 of the inner frame assembly 2. A transmission rod 303 is rotatably mounted on the trigger frame 301. The transmission rod 303 is shaped like an hourglass. The other end of the trigger frame 301 is set as a contact wheel 302. The end of the contact wheel 302 is set as a groove structure. First, the trigger frame 301 is hinged, which allows the trigger frame 301 to swing flexibly. The transmission rod 303 of the trigger frame 301 is shaped like an hourglass, which allows the transmission rod 303 to better contact the edge of the conveyor belt 102 on the conveyor assembly 1. After the conveyor belt 102 is offset, it will directly contact the transmission rod 303, realizing the drive of the transmission rod 303 to the trigger frame 301. At this time, the contact wheel 302 at the trigger frame 301 swings, and the groove structure on the contact wheel 302 can drive the transmission assembly 4, realizing the stable transmission effect of the trigger assembly 3 to the transmission assembly 4.

[0041] Among them, such as Figure 4 Figure 5 As shown, the drive rod 401 of the transmission assembly 4 is configured as a long rod, and an external protrusion 403 is provided on the drive rod 401. The external protrusion 403 is connected to the trigger assembly 3. The driven shaft 402 of the transmission assembly 4 is rotatably mounted on the extension frame 202 of the inner frame assembly 2. The drive rod 401 and the driven shaft 402 are driven by a gear and rack mechanism. First, the external protrusion 403 is connected to the trigger assembly 3 to realize the sliding drive of the trigger assembly 3 to the transmission assembly 4. At this time, the drive rod 401 drives the driven shaft 402 through the gear and rack mechanism to realize the rotation of the driven shaft 402, so that the driven shaft 402 drives the lifting assembly 5, thus completing the stable transmission of the transmission assembly 4 to the lifting assembly 5.

[0042] Among them, such as Figure 3 Figure 5 As shown, the sliding block 501 of the lifting assembly 5 is slidably installed on the extension frame 202 of the inner frame assembly 2. The bottom of the sliding block 501 is connected to the driven shaft 402 of the transmission assembly 4. The support frame 503 of the lifting assembly 5 is hingedly installed on the inner frame assembly 2. The bottom of the support frame 503 is connected to the sliding block 501 with a support plate 502. An auxiliary roller 7 is rotatably installed on the support frame 503. First, the transmission between the driven shaft 402 and the sliding block 501 adopts a threaded transmission method, so that the transmission assembly 4 can stably transmit the lifting assembly 5. After the sliding block 501 slides, it can lift the support frame 503 through the support plate 502, so that the support frame 503 can swing at an angle. After the auxiliary roller 7 is lifted at a certain angle, the tension of the conveyor belt 102 is increased and reset by the auxiliary roller 7, so as to achieve the correction effect of the auxiliary roller 7 on the conveyor belt 102.

[0043] Among them, such as Figure 2 Figure 3As shown, the lifting component 5 and triggering component 3 installed on the inner frame assembly 2 are both set in two symmetrical groups. The inner frame assembly 2 on the conveyor assembly 1 is set in two symmetrical groups. Each inner frame assembly 2 is set at the head of the conveyor belt 102 near the conveyor assembly 1. Usually, the offset of the conveyor belt 102 is mostly at the head. Therefore, the inner frame assembly 2 is installed at the head of the conveyor belt 102 on the conveyor assembly 1. The lifting component 5 and triggering component 3 on the inner frame assembly 2 are both set in two symmetrical groups to achieve the effect of stable automatic correction from both ends of the conveyor belt 102.

[0044] The working principle of this embodiment is as follows: When the device is running, the conveyor belt 102 of the conveyor assembly 1 deviates, causing the trigger assembly 3 at the outer edge of the conveyor belt 102 to partially contact. After being driven, the trigger assembly 3 will drive the transmission assembly 4, causing the transmission assembly 4 to slide. At this time, the transmission assembly 4 drives the lifting assembly 5 through the gear and rack structure. The lifting assembly 5 is equipped with an auxiliary roller 7, which lifts the auxiliary roller 7 at a certain angle, thereby allowing the auxiliary roller 7 to lift the conveyor belt 102 and reset it. After the conveyor belt 102 separates from the external trigger assembly 3, the tension spring 6 can pull the transmission assembly 4 to reset it, ensuring the stable correction of the conveyor belt 102.
