[0003] Currently, the legs and frame are usually connected by two U-shaped components arranged opposite each other. The U-shaped components include a first set of connecting bolts and a second set of connecting bolts, as well as two connecting plates arranged opposite each other. The bottom of the connecting plates is used to install the legs. The first set of connecting bolts and the second set of connecting bolts pass through between the two connecting plates. The first set of connecting bolts overlaps on the upper wing of the channel steel beam, and the second set of connecting bolts abuts against the bottom of the lower wing of the channel steel beam.

[0004] However, the U-shaped assembly is prone to interference with structures such as idler roller frames and enclosed frame frames mounted on the machine frame. Utility Model Content

[0005] This application provides a connecting mechanism and a belt conveyor that can avoid structural interference between the connecting mechanism and other structures on the frame.

[0009] In one possible implementation, the upper surface of the lower wing is a first inclined surface; the clamping block includes a pressing part, the bottom of which has a pressing surface, the pressing surface abutting against the first inclined surface.

[0010] In one possible implementation, the pressing surface is a bevel, a stepped surface, or a serrated surface.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] In related technologies, belt conveyors using U-shaped assemblies to connect the outriggers and the frame present a technical problem: the U-shaped assemblies occupy space on the frame, potentially causing interference with structures such as idler frames and enclosed frame frames mounted on the frame. This problem arises because the outriggers are mounted on the channel steel beams of the frame via the U-shaped assemblies. The U-shaped assemblies consist of a first set of connecting bolts, a second set of connecting bolts, and two opposing connecting plates. The first and second sets of connecting bolts pass between the two connecting plates. The first set of connecting bolts overlaps the upper flange of the channel steel beam, and the second set abuts against the bottom of the lower flange of the channel steel beam, resulting in the U-shaped assemblies occupying a significant amount of space on the channel steel beam. Furthermore, structures such as idler frames and enclosed frame frames are typically mounted on the channel steel beams of the frame, making it easy for the U-shaped assemblies to interfere with these structures.

[0037] To address the aforementioned technical problems, this application provides a connecting mechanism and a belt conveyor. The connecting mechanism is fixed to the lower wing and support wing of the channel steel beam by mounting outriggers on the connecting mechanism. This eliminates the need to occupy space above the channel steel beam, thereby avoiding interference with structures such as idler frames and enclosed frame frames on the belt conveyor frame.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] refer to Figure 1 and Figure 2 The belt conveyor provided in this application embodiment includes a frame 10, a connecting mechanism 20, and support legs.

[0040] The frame 10 is the main body of the belt conveyor. A conveyor belt can be installed on the frame 10 to realize material transportation. The bottom of the frame 10 has a channel steel beam 11, which is composed of channel steel. The channel steel is a long strip of steel with a U-shaped cross-section. (Refer to...) Figure 1 and Figure 2The channel steel beam 11 includes an upper wing 111, a lower wing 112, and a support wing 113. The two ends of the support wing 113 are connected to the upper wing 111 and the lower wing 112, respectively. The upper wing 111, lower wing 112, and support wing 113 surround and form a groove 114. The outriggers support the frame 10 and can be elongated, cylindrical, or similar shapes. The bottom of the outriggers is typically fixed to the ground, and the top of the outriggers is mounted on the frame 10 via a connecting mechanism 20.

[0041] refer to Figure 1 and Figure 2 The connecting mechanism 20 includes a clamping block 21, a connecting seat 22, and a fastener 23. The connecting mechanism 20 grips the channel steel beam 11 through the connecting seat 22, and the clamping block 21 presses the channel steel beam 11 onto the connecting seat 22 to fix the connecting mechanism 20 onto the channel steel beam 11.

[0042] The connecting seat 22 includes a support plate 221 and a limiting plate 222. The support plate 221 abuts against the lower surface of the lower wing 111, in other words, the support plate 221 abuts against the bottom of the lower wing 112, and the lower wing 112 is pressed against the support plate 111.

[0043] The limiting plate 222 is mounted on the support plate 221, for example, the limiting plate 222 is welded to the support plate, or the limiting plate 222 and the support plate 221 are an integral structure formed by sheet metal or machining. The limiting plate 222 and the clamping block 21 are located on both sides of the channel steel beam 11, wherein the limiting plate 222 abuts against the side of the support wing 113 facing away from the groove 114, and the clamping block 21 presses against the upper surface of the lower wing 112, or in other words, the clamping block 21 presses against the bottom groove wall of the groove 114 of the channel steel beam 11.

[0044] refer to Figure 2 The support plate 221 and the limiting plate 222 form a structure that is approximately hand-shaped, with the support plate 221 resembling a palm and the limiting plate 222 resembling fingers, so that the support plate 221 and the limiting plate 222 grip the channel steel beam 11 to constrain the downward and backward movement of the channel steel beam 11.

[0045] The clamping block 21 is pressed onto the lower wing 112, and the clamping block 21 and the support plate 221 are connected by a fastener 23, which can be a clamping bolt. The clamping bolt passes between the clamping block 21 and the support plate 221 to form a clamping force between the clamping block 21 and the support plate 221, thereby causing the clamping block 21 to press against the lower wing 112 on the support plate 221. The clamping block 21 constrains the upward, forward, and left-right movement of the channel steel beam 11, thereby fixing the connecting mechanism 20 onto the channel steel beam 11.

[0046] The connecting mechanism 20 provided in this embodiment is fixed to the bottom of the lower wing 112 and the support wing 113 of the channel steel beam 11, without occupying the space above the channel steel beam 11, thus avoiding interference between the connecting mechanism 20 and structures such as the idler frame and the enclosed frame installed on the frame 10. Furthermore, compared to welding the legs to the channel steel beam 11, the connecting mechanism provided in this application facilitates adjustment of the installation position of the legs on the channel steel beam 11 to adapt to different working scenarios. Compared to installing the legs on the channel steel beam 11 via threaded connections, the belt conveyor provided in this application does not require pre-machining holes in the channel steel beam 11.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the upper surface of the lower wing 112 is a first inclined surface 112a. For example, the lower wing 112 gradually thins from its root to its edge, where the root of the lower wing 112 is the end where it connects to the supporting wing 113, and the edge of the lower wing 112 is the end where it is not connected to the supporting wing 113. Compared to a lower wing 112 with uniform thickness at all parts, this increases the bending resistance of the lower wing 112 and the channel steel beam 11.

[0048] like Figure 2 As shown, the clamping block 21 includes a clamping portion 211, the bottom of which has a clamping surface 211a, which abuts against a first inclined surface 112a. By abutting the clamping block 21 against the first inclined surface 112a, compared to the clamping block 21 and the lower wing 112 contacting each other through two horizontal surfaces, this embodiment of the application sets the abutting surface between the lower wing 112 and the clamping block 21 as the first inclined surface 112a, which increases the contact area between the clamping block 21 and the lower wing 112, thereby improving the connection reliability between the clamping block 21 and the lower wing 112.

[0049] Furthermore, the contact surface of the clamping block 21 is set as a first inclined surface 112a. The clamping block 21 can provide a clamping force perpendicular to the first inclined surface 112a. This clamping force can be decomposed into a horizontal component and a vertical component, so that the clamping block 21 clamps the lower wing 112 in both the horizontal and vertical directions, thereby further improving the connection reliability between the clamping block 21 and the lower wing 112.

[0050] Based on the above embodiments, such as Figure 3-5 As shown, the pressing surface 211a is a bevel, a stepped surface, or a serrated surface.

[0051] refer to Figure 3 The pressing surface 211a is an inclined surface, which can be an inclined surface parallel to the first inclined surface 112a, so that the inclined surface abuts against the first inclined surface 112a, thereby realizing the contact between the pressing block 21 and the lower wing 112.

[0052] refer to Figure 4The pressing surface 211a is a stepped surface, which includes multiple alternating horizontal and vertical segments. The edge at the connection between the horizontal and vertical segments abuts against the first inclined surface 112a, so that the stepped surface abuts against the first inclined surface 112a, thereby achieving the contact between the pressing block 21 and the lower wing 112.

[0053] refer to Figure 5 The pressing surface 211a is a serrated surface with a wavy shape. The tooth tip of the serrated surface abuts against the first inclined surface 112a so that the stepped surface abuts against the first inclined surface 112a, thereby realizing the contact between the pressing block 21 and the lower wing 112.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the clamping block 21 also includes a connecting part 212 connected to the pressing part 211. The connecting part 212 is a structure for connecting the clamping block 21 and the fastener 23. The connecting part 212 is located on the side of the pressing part 211 facing away from the channel steel beam 111, and the connecting part 212 and the pressing part 211 can be an integrally formed structure.

[0055] The connecting part 212 can be a rectangular block, and its bottom is pressed against the support plate 221. The support plate 221 has a first through hole 221a, and the connecting part 212 has a threaded hole 212a, with the center lines of the threaded hole 212a and the first through hole 221a being the same. A fastener 23 passes between the first through hole 221a and the threaded hole 212a, thereby locking the connecting part 212 and the support plate 221, and further pressing the clamping block 21 against the lower wing 112 between the clamping block 21 and the support plate 221.

[0056] refer to Figure 1 and Figure 2 In some embodiments, the connecting mechanism 20 further includes a backstop component 24, which is used to restrict the movement of the clamping block 21 away from the support wing 114 of the channel steel beam 11. When the upper surface of the lower wing 112 is the first inclined plane 112a, due to the influence of gravity, the clamping block 21 may slide in the direction away from the support wing 114. The backstop component 24 abuts against the side of the clamping block 21 away from the channel steel beam 11 to restrict the clamping block 21 from sliding down along the first inclined plane 112a.

[0057] In one possible implementation, refer to Figure 1 and Figure 2The anti-reverse assembly 24 includes an anti-reverse seat 241, an anti-reverse bolt 242, and an anti-reverse nut 243. The anti-reverse seat 241 can be a rectangular plate, a near-rectangular plate, a circular plate, or a near-circular plate. The anti-reverse seat 241 is mounted on the support plate 221, for example, the anti-reverse seat 241 is welded to the support plate 221, or the anti-reverse seat 241 and the support plate 221 are integrally formed by sheet metal work or machining. The anti-reverse seat 241 is located on the side of the clamping block 21 facing away from the channel steel beam 11.

[0058] The anti-reverse nut 243 is located on the side of the anti-reverse seat 241 away from the channel steel beam 11. For example, the anti-reverse nut 243 is pressed against the side of the anti-reverse seat 241 facing away from the support wing 114. The anti-reverse seat 241 has a second through hole, which is concentric with the anti-reverse nut 243. The anti-reverse bolt 242 passes through the anti-reverse nut 243 and the second through hole in sequence and abuts against the clamping block 21 to prevent the clamping block 21 from sliding down the first inclined surface 112a.

[0059] In some embodiments, reference Figure 1 and Figure 2 The connecting mechanism 20 also includes a mounting plate 25 for mounting the outriggers. The mounting plate 25 is attached to the lower surface of the support plate 221. The mounting plate 25 can be welded to the lower surface of the support plate 221, or the mounting plate and the support plate 221 can be integrally formed by sheet metal work or machining. The mounting plate has mounting holes 251 for mounting the outriggers. For example, the outriggers are mounted on the mounting holes 251 by threaded connection.

[0060] Compared to directly mounting the outriggers on the lower surface of the support plate 221, this embodiment of the application provides a mounting plate 25 on the lower side of the support plate 221, and connects the outriggers to the mounting plate 25, which facilitates the installation of the outriggers in a vertical or near-vertical direction, so that the outriggers can be installed on the frame 10 through the connecting mechanism to support the frame 10.

[0061] In some embodiments, the support leg is hinged to the mounting plate 25 via mounting holes 251. For example, the top of the support leg has a hinge plate with hinge holes, and a pin passes through the hinge holes and mounting holes 251. Hinging the support leg to the mounting plate 25 allows for adjustment of the angle between the support leg and the support 10, facilitating the belt conveyor to adjust its tilt angle to meet the material conveying needs of different scenarios.

[0062] In some embodiments, reference Figure 1The connecting mechanism 20 contains multiple clamping blocks 21, such as two, three, or more. These clamping blocks 21 are spaced apart along the length of the lower wing 112, ensuring that all blocks 21 are pressed firmly against the lower wing 112. Compared to a single clamping block 21, multiple clamping blocks 21 press the lower wing 112 against the support plate 221, further enhancing the connection strength between the clamping blocks 21, the support plate 221, and the lower wing 112.

[0063] On the other hand, this application provides a belt conveyor, including a frame 10, legs and the aforementioned connecting mechanism 20, the legs being mounted on the connecting mechanism 20, and the connecting mechanism 20 being mounted on the channel steel beam 11 of the frame 10.

[0064] In this embodiment of the belt conveyor, the support legs are mounted on the connecting mechanism 20, and the connecting mechanism 20 is fixed to the lower wing 112 and the support wing 113 of the channel steel beam 11. Compared with related technologies, the connecting mechanism does not need to occupy the space above the channel steel beam, thereby avoiding interference between the connecting mechanism 20 and structures such as the idler frame and the enclosed frame installed on the frame 10.

[0065] In some embodiments, there are multiple support legs and connecting mechanisms 20. The length of each support leg decreases sequentially along the length direction of the lower wing 112, or in other words, the length of each support leg decreases sequentially from the top end to the bottom end of the frame 10. The support legs are spaced apart along the length direction of the lower wing 112, and each support leg is mounted on the channel steel beam 11 through a corresponding connecting mechanism 20. This creates an angle between the frame 10 and the horizontal plane, causing the belt conveyor to be inclined, thereby realizing the transmission of materials along the height direction.
