Description

Technical Field

[0001] This utility model relates to the field of belt conveyor equipment technology, and in particular to a belt conveyor frame structure and a telescopic belt conveyor vehicle. Background Technology

[0002] Belt conveyors, with their advantages of large conveying capacity, simple structure, and convenient maintenance, are widely used in the transport of building materials such as concrete, agricultural products such as grain, mineral products such as coal, and chemical materials such as plastic granules. They are mainly used to transport granular, powdery, and lumpy loose materials, as well as packaged items such as boxes and parcels. In applications involving long-distance conveying, conveying from high to low or low to high, belt bends are inevitable, and material spillage can easily occur at these bends. Utility Model Content

[0003] Therefore, it is necessary to provide a belt conveyor frame and telescopic belt conveyor vehicle that can reduce the bending angle of the conveyor belt, ensure that the conveyor belt can smoothly transition at the bend, reduce the probability of material spillage during the conveying process, and improve the reliability of the conveying.

[0004] A belt conveyor frame structure, comprising:

[0005] The frame has two mounting planes and a mounting ramp that is inclined downward relative to each of the mounting planes; the extension direction of the mounting ramp and the extension direction of the mounting plane are defined together as a first direction; the two mounting planes are spaced apart along a second direction perpendicular to the first direction to form a conveying interval;

[0006] Multiple support groups are spaced apart along the first direction; each support group includes two support seats fixed at a distance along the second direction to the mounting slope; each support seat has a connecting surface at its top; the distance between the connecting surface of the multiple support groups and the mounting slope decreases sequentially along the first direction, and each connecting surface is lower than the mounting plane;

[0007] Multiple first roller groups are spaced apart along the first direction and correspond one-to-one with the multiple support groups; the two ends of the first roller groups are detachably connected to two connecting surfaces in the corresponding support groups.

[0008] Multiple second roller groups are spaced apart along the first direction; each second roller group is detachably connected to two of the mounting planes.

[0009] The aforementioned belt conveyor frame structure and telescopic belt conveyor vehicle reduce the bending angle of the conveyor belt between the mounting slope and the mounting plane by fixing multiple support groups to the inclined surface, and by detachably mounting the two ends of the first idler group to the two connecting surfaces of the corresponding support groups, while detachably mounting the two ends of the second idler group directly to the two mounting planes. Furthermore, the distance between the connecting surfaces of the multiple support groups and the inclined surface decreases sequentially along the first direction, further reducing the bending angle of the conveyor belt between the inclined surface and the mounting plane. This belt conveyor frame structure, without changing the inclination angle of the inclined surface relative to the mounting plane, reduces the bending angle of the conveyor belt at the connection point between the inclined surface and the mounting plane, ensuring a smooth transition of the conveyor belt at the bends in the frame, effectively reducing the probability of material spillage during conveying, and improving the reliability of material conveying.

[0020] This utility model provides a belt conveyor frame structure and a telescopic belt conveyor vehicle. The telescopic belt conveyor vehicle includes a boom, a belt conveyor frame structure, and a conveyor belt. The belt conveyor frame structure is mounted on the boom, and the conveyor belt is installed on the belt conveyor frame structure. Thus, the belt conveyor frame structure is used in a telescopic belt conveyor vehicle.

[0021] Of course, in other embodiments, the belt conveyor frame structure can also be used in other belt conveyor equipment or belt conveyor lines that require belt bending. In the embodiments of this utility model, the application of the belt conveyor frame structure on a telescopic belt conveyor vehicle is used as an example for illustration.

[0022] Appendix Figure 1 The diagram illustrates the structure of a belt conveyor frame according to one embodiment of the present invention. For ease of explanation, the accompanying drawings only show structures relevant to embodiments of the present invention.

[0023] Please see Figure 1 and Figure 2 The belt conveyor frame structure 100 in the preferred embodiment of this utility model includes a frame 110, multiple support groups 120, multiple first idler roller groups 130 and multiple second idler roller groups 140.

[0024] The frame 110 has two mounting planes 111 and a downwardly inclined mounting surface 112 relative to each mounting plane 111. The extension direction of the inclined mounting surface 112 and the extension direction of the mounting plane 111 are defined together as a first direction 10, which is a curved direction extending along the inclined mounting surface 112 and the mounting plane 111. The two mounting planes 111 are spaced apart along a second direction 20 perpendicular to the first direction 10 to form a conveying interval 113. It should be noted that the mounting plane 111 is a horizontally arranged plane, which can be a horizontal plane or a plane inclined upwards or downwards at a small angle relative to a horizontal plane, such as a plane inclined at an angle of a few degrees or tens of degrees relative to a horizontal plane.

[0025] Please refer to the following: Figure 3Multiple support groups 120 are spaced apart along a first direction 10. Each support group 120 includes two support bases 121 fixed at a distance along a second direction 20 to a mounting ramp 112. Each support base 121 has a connecting surface 1211 at its top. The distance between the connecting surfaces 1211 of the multiple support groups 120 and the mounting ramp 112 decreases sequentially along the first direction 10, and each connecting surface 1211 is lower than the mounting plane 111.

[0026] Multiple first roller groups 130 are spaced apart along a first direction 10 and correspond one-to-one with multiple support groups 120. The two ends of each first roller group 130 are detachably connected to two connecting surfaces 1211 in the corresponding support group 120. The structures of the multiple first roller groups 130 may be identical or not identical.

[0027] Multiple second roller groups 140 are spaced apart along a first direction 10. Each second roller group 140 is detachably connected to two mounting planes 111. The structures of the multiple second roller groups 140 may or may not be identical.

[0028] In the telescopic belt conveyor, the frame 110 is part of the boom, and the conveyor belt is respectively attached to a plurality of first idler sets 130 and a plurality of second idler sets 140. Specifically, the first direction 10 is a curved direction consistent with the conveying direction of the conveyor belt. Of course, in other embodiments, such as belt conveyor equipment, belt conveyor lines, etc., the frame 110 is part of the frame, or it can be part of other structures that serve a supporting and connecting function.

[0029] The aforementioned belt conveyor frame structure 100 reduces the bending angle of the conveyor belt between the mounting slope 112 and the mounting plane 111 by fixing multiple support groups 120 to the inclined surface, detachably mounting the two ends of the first idler group 130 to the two connecting surfaces 1211 of the corresponding support group 120, and detachably mounting the two ends of the second idler group 140 directly to the two mounting planes 111. Furthermore, the distance between the connecting surfaces 1211 of the multiple support groups 120 and the inclined surface 112 decreases sequentially along the first direction 10, further reducing the bending angle of the conveyor belt between the inclined surface 112 and the mounting plane 111. The aforementioned belt conveyor frame structure 100, without changing the inclination angle of the mounting slope 112 relative to the mounting plane 111, can reduce the bending angle of the conveyor belt between the mounting slope 112 and the mounting plane 111, ensuring that the conveyor belt can smoothly transition at the bend, effectively reducing the probability of material spillage during the conveying process, and improving the reliability of material conveying.

[0030] In some embodiments, the support base 121 includes two parallel and spaced-apart vertical support plates 1212 and a horizontal support plate 1213 connected to the two vertical support plates 1212. The ends of the two vertical support plates 1212 away from the horizontal support plate 1213 are fixedly connected to the mounting inclined surface 112. The surface of the horizontal support plate 1213 facing away from the mounting inclined surface 112 is the connecting surface 1211. The support base 121 can be a spliced ​​structure formed by welding, screwing, or other methods to fix the vertical support plates 1212 and the horizontal support plate 1213; it can also be an integral structure formed by bending a single plate twice; or it can be an integral structure formed by 3D printing or other integral molding methods.

[0031] The support base 121 is configured with two vertical support plates 1212 and a horizontal support plate 1213 to reduce the weight of the support base 121, which is beneficial to the strength of the belt conveyor frame structure 100. At the same time, it also leaves installation space between the horizontal support plate 1213 and the mounting slope 112, which facilitates the installation operation of the first idler roller group 130 on the support base 121.

[0032] Of course, in other embodiments, the support base 121 can also be a block-shaped, column-shaped, rod-shaped, frame-shaped, or other structure.

[0033] In some embodiments, a first connecting hole 1214 is provided on the connecting surface 1211. First mounting holes 131 are provided at both ends of the first idler roller assembly 130. A first connector (not shown) passes through each first mounting hole 131. One end of the first connector extends out of the first mounting hole 131 and is detachably connected to the first connecting hole 1214, so as to detachably connect one end of the first idler roller assembly 130 to the corresponding connecting surface 1211.

[0034] Each mounting surface 111 is provided with a plurality of second connecting holes (not shown). Each second idler roller assembly 140 has a second mounting hole 141 at both ends. A second connector (not shown) passes through each second mounting hole 141. One end of the second connector extends out of the second mounting hole 141 and is detachably connected to the second connecting hole, thereby detachably connecting one end of the second idler roller assembly 140 to the corresponding mounting surface 111. The first and second connectors can be bolts, bolt-nut assemblies, screws, screw-nut assemblies, etc.

[0035] When it is necessary to install the first idler roller assembly 130 onto the corresponding support base 121, or to remove the first idler roller assembly 130 from the support base 121, simply rotate the first connecting member in either the forward or reverse direction. Similarly, when it is necessary to install the second idler roller assembly 140 onto the mounting surface 111, or to remove the second idler roller assembly 140 from the mounting surface 111, simply rotate the second connecting member in either the forward or reverse direction. Therefore, the design of the first and second connecting members makes the installation and maintenance of the first idler roller assembly 130 and the second idler roller assembly 140 more convenient.

[0036] In one embodiment of this utility model, both the first idler group 130 and the second idler group 140 are trough-shaped idler groups. In the telescopic belt conveyor, after the material is placed on the conveyor belt, the conveyor belt is pressed against the first idler group 130 and the second idler group 140 by the material, thereby forming a groove in the conveyor belt. Therefore, by setting the first idler group 130 and the second idler group 140 as trough-shaped idler groups, it is not necessary to add material blocking structures on both sides of the conveyor belt, and the probability of material spillage during the conveying process is further reduced, thus taking into account the advantages of simple structure and reliable conveying.

[0037] Please refer to the following: Figure 4 and Figure 5 Specifically, the first idler assembly 130 includes a first idler frame 132, a first lower idler 133, and two first side idlers 134. The two ends of the first idler frame 132 are detachably mounted to the two connecting surfaces 1211 of the corresponding support assembly 120. The first lower idler 133 is mounted on the first idler frame 132, with its central axis parallel to the second direction 20. The two first side idlers 134 are spaced apart along the second direction 20 on the first idler frame 132 and are inclined upwards relative to the first lower idler 133. In the first idler assembly 130, the first lower idler 133 is located between the two first side idlers 134.

[0038] The second idler assembly 140 includes a second idler frame 142, a second lower idler 143, and two second side idlers 144. The two ends of the second idler frame 142 are detachably mounted on two mounting surfaces 111. The second lower idler 143 is mounted on the second idler frame 142, with its central axis parallel to the second direction 20. The two second side idlers 144 are spaced apart along the second direction 20 on the second idler frame 142 and are inclined upwards relative to the second lower idler 143. In the second idler assembly 140, the second lower idler 143 is located between the two second side idlers 144.

[0039] In a telescopic belt conveyor, when the conveyor belt is idling, it moves along the conveying direction under the drive of the first side idler 134 and the second side idler 144. When the conveyor belt is in the material conveying state, the conveyor belt is pressed by the material onto the first side idler 134, the first lower idler 133, the second side idler 144, and the second lower idler 143, causing the conveyor belt to form a groove. At this time, when the conveyor belt moves forward along the conveying direction, the first side idler 134, the first lower idler 133, the second side idler 144, and the second lower idler 143 will all rotate, making the movement of the conveyor belt more sensitive and labor-saving during material conveying. This reduces the power requirements of the telescopic belt conveyor during material conveying, helps to reduce energy consumption during material conveying, and further reduces the probability of material spillage during conveying, thus further improving the reliability of material conveying.

[0040] More specifically, the first lower idler roller 133 includes a first lower roller 1331 and a first lower roller shaft 1332. The first lower roller 1331 is rotatably mounted on the first lower roller shaft 1332. The first side idler roller 134 includes a first side roller 1341, a first side roller shaft 1342, and a first connecting frame 1343. The first side roller 1341 is rotatably mounted on the first side roller shaft 1342. One end of the first side roller shaft 1342 extends outside the first side roller 1341 and is fixedly connected to the first connecting frame 1343 and to one end of the first lower roller shaft 1332. The other end of the first connecting frame 1343 extends to the other end of the first side roller 1341 and is detachably connected to one end of the first idler roller frame 132. Thus, both ends of the first lower idler roller 133 are detachably mounted on the first idler roller frame 132 via the first side idler roller 134.

[0041] The second lower idler roller 143 includes a second lower roller 1431 and a second lower roller shaft 1432. The second lower roller 1431 is rotatably mounted on the second lower roller shaft 1432. The second side idler roller 144 includes a second side roller 1441, a second side roller shaft 1442, and a second connecting frame 1443. The second side roller 1441 is rotatably mounted on the second side roller shaft 1442. One end of the second side roller shaft 1442 extends outside the second side roller 1441 and is fixedly connected to the second connecting frame 1443 and to one end of the second lower roller shaft 1432. The other end of the second connecting frame 1443 extends to the other end of the second side roller 1441 and is detachably connected along the second idler roller frame 142. Thus, both ends of the second lower idler roller 143 are detachably mounted on the second idler roller frame 142 via the second side idler rollers 144.

[0042] Thus, during the assembly of the first idler group 130 and the second idler group 140, after the first lower roller 1331 is rotatably mounted on the first lower roller shaft 1332 and the first side roller 1341 is rotatably mounted on the first side roller shaft 1342, the two ends of the first lower roller shaft 1332 are respectively movably connected to one end of the two first side roller shafts 1342, and then the two first side roller shafts 1342 are respectively mounted on both ends of the first idler frame 132; the assembly process of the second idler group 140 is the same as that of the first idler group 130, and will not be described again here. Therefore, the first lower idler roller 133 and the first side idler rollers 134 located at both ends of the first lower idler roller 133 are connected in series and connected to the first idler frame 132 through two first side roller shafts 1342. The second lower idler roller 143 and the second side idler rollers 144 located at both ends of the second lower idler roller 143 are connected in series and connected to the second idler frame 142 through two second side roller shafts 1442. This allows the first lower idler roller 133 and the second lower idler roller 143 to move within a certain range. Even if the amount of material on the conveyor belt varies during the material conveying process, it can ensure that each first lower idler roller 133 and each second lower idler roller 143 can effectively adhere to the conveyor belt, ensuring that the conveyor belt is flat and reducing the probability of dents or bulges forming on the conveyor belt due to varying material amounts, thereby increasing the resistance of the conveyor belt and further improving the reliability of material conveying.

[0043] Of course, in other embodiments, the first lower roller 1332 and the first side roller 1342 can be independently mounted on the first roller frame 132, and the second lower roller 1432 and the second side roller 1442 can be independently mounted on the second roller frame 142.

[0044] More specifically, both ends of the first lower roller shaft 1332 are rotatably connected to a first pin connector 135. The end of the first pin connector 135 away from the first lower roller shaft 1332 is rotatably connected to the end of the first side roller shaft 1342 near the first lower roller 1331. Both ends of the second lower roller shaft 1432 are rotatably connected to a second pin connector 145. The end of the second pin connector 145 away from the second lower roller shaft 1432 is rotatably connected to the end of the second side roller shaft 1442 near the second lower roller 1431. The first pin connector 135 has two ends that are rotatably connected to one end of the first lower roller 1332 and one end of the first side roller 1342 respectively via pins. The second pin connector 145 has two ends that are rotatably connected to one end of the second lower roller 1432 and one end of the second side roller 1442 respectively via pins. This achieves the rotatable connection between the first lower roller 133 and the first side roller 134, and the rotatable connection between the second lower roller 143 and the second side roller 144.

[0045] More specifically, the first idler frame 132 includes two first connecting plates 1321 and two first side connecting plates 1322. One end of each of the two first connecting plates 1321 is detachably connected to two connecting surfaces 1211 in the corresponding support assembly 120, and the other end is inclined upward relative to the corresponding connecting surface 1211. The two first side connecting plates 1322 are parallel and spaced apart along the first direction 10. Both ends of each first side connecting plate 1322 are detachably connected to the other ends of the two first connecting plates 1321. The first lower idler 133 and the first side idler 134 are both located between the two first side connecting plates 1322. The extending direction of the first side connecting plate 1322 is consistent with the axial direction of the first side idler 134, the first lower idler 133, and the first side idler 134.

[0046] The second idler frame 142 includes two second connecting plates 1421 and two second side connecting plates 1422. One end of each of the two second connecting plates 1421 is detachably connected to two connecting surfaces 1211 in the corresponding support assembly 120, and the other end is inclined upward relative to the corresponding connecting surface 1211. The two second side connecting plates 1422 are parallel and spaced apart along the second direction 20. Both ends of each second side connecting plate 1422 are detachably connected to the other ends of the two second connecting plates 1421. The second lower idler 143 and the second side idler 144 are both located between the two second side connecting plates 1422. The extending direction of the second side connecting plates 1422 is consistent with the axial direction of the second side idler 144, the second lower idler 143, and the second side idler 144.

[0047] The first idler frame 132 is configured with two first connecting plates 1321 and two first side connecting plates 1322, such that the first side idler 134 and the first lower idler 133 are located between the two first side connecting plates 1322 and connected to the two first connecting plates 1321. This allows the first side connecting plates 1322 to protect and limit the first side idler 134 and the first lower idler 133, preventing the first lower idler 133 from moving too far forward under the drive of the conveyor belt, thus avoiding severe wear at the connection point with the first side idler 134. This helps extend the service life of the belt conveyor frame structure 100. Similarly, configuring the second idler frame 142 with two second connecting plates 1421 and two second side connecting plates 1422 also prevents the second lower idler 143 from moving too far forward under the drive of the conveyor belt, thus avoiding severe wear at the connection point with the second side idler 144, further extending the service life of the belt conveyor frame structure 100.

[0048] In another embodiment of this utility model, both the first idler group 130 and the second idler group 140 are flat idler groups. The frame 110 is provided with two parallel and spaced-apart retaining edges (not shown). Both the first idler group 130 and the second idler group 140 are located between the two retaining edges, and the tops of the retaining edges are respectively higher than the highest points of the roller surfaces of the first idler group 130 and the second idler group 140. In a telescopic belt conveyor, the tops of the retaining edges are higher than the conveying surface of the conveyor belt.

[0049] Thus, both the first idler group 130 and the second idler group 140 are set as flat idler groups, and a material stop is set on both sides of the conveyor belt, so that a material conveying trough is formed between the two material stop and the conveyor belt, which can further reduce the probability of material spillage while conveying materials.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
