Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor correction structure, and in particular relates to a double-stop correction structure for the bearing section of a belt conveyor. Background Technology

[0002] Belt conveyors are widely used in power plants, coal mines, ports, chemical industries, and other sectors. Their stable operation directly affects conveying efficiency and capacity. In actual operation, belt misalignment in the carrying or return sections is a significant factor affecting the overall stability of the machine. Corresponding correction structures are typically designed and implemented to eliminate this impact on the normal operation of the belt conveyor. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model proposes a correction structure suitable for the load-bearing section, specifically as follows:

[0004] The belt conveyor's carrying section features a double-stage correction structure, including a support frame and a V-shaped idler frame. The V-shaped idler frame consists of a horizontal crossbeam in the middle and inclined beams on both sides. Horizontal rollers are supported on the crossbeams, and inclined rollers are supported on each side of the inclined beams. The V-shaped idler frame and the support frame are rotatably connected by a rotating assembly. At the outer end of each inclined beam, a correction side vertical roller and a correction upper horizontal roller are respectively arranged. The projections of the upper horizontal roller and the upper part of the correction side vertical roller on the same side, and the lower part of the correction side vertical roller and the outer end of the inclined roller on the same side, intersect in the direction of the conveyor belt's travel. The three components are connected end to end on the projection surface to form a hook-shaped correction structure.

[0005] Furthermore, the rotation axis of the straightening side vertical roller is perpendicular to the rotation axis of the inclined roller on the same side. The rotation axes of the two straightening side vertical rollers are located in the same vertical plane. The vertical plane where the rotation axes of the two straightening side vertical rollers are located is parallel to the vertical plane where the rotation axes of the two inclined rollers are located. Moreover, most of the roller body of the straightening side vertical roller is higher than the highest point of the roller body surface of the inclined roller. At the same time, the roller body of the straightening side vertical roller is located between the two ends of the roller body axis line of the inclined roller and is relatively close to the outer end.

[0006] Furthermore, the rotation axis of the upper horizontal roller is located directly above the rotation axis of the inclined roller on the same side, and both are in the same vertical plane. The rotation axis of the upper horizontal roller is parallel to the rotation axis of the horizontal roller.

[0007] Furthermore, it also includes a limiting plate, the bottom of which is fixed to the support frame. The crossbeam of the V-shaped roller frame is made of angle iron and faces downward. The limiting plate extends vertically upward and its top extends into the opening below the crossbeam. Chamfered edges are formed on both sides of the top of the limiting plate. Each chamfered edge limits the rotation angle of the crossbeam around the axis of the rotating assembly by abutting the corresponding corner plate of the crossbeam made of angle iron.

[0008] Furthermore, the roller shaft of the upper horizontal roller can be inserted into the tube hole of the stepped mounting tube. The outer tube surface of the stepped mounting tube is divided into a thick section and a thin section, and an annular shoulder is formed at the junction of the two. The thick section has a threaded hole, and the fastening bolt is screwed through the threaded hole and abuts against the roller shaft, thereby fixing the roller shaft of the upper horizontal roller to the stepped mounting tube. The thin section passes through the through holes on the two sides of the square tube steel, and is limited by the annular shoulder and abutting against one side of the plate. The stepped mounting tube is fixed to the square tube steel by welding.

[0009] Furthermore, the square tube steel is welded and fixed to the inclined beam; a support groove is opened on one side plate of the square tube steel for inserting and supporting the outer end of the inclined roller shaft.

[0010] Furthermore, the bottom of the square tube steel is welded and fixed to the triangular tube steel. The wall of the triangular tube steel has a relief groove extending towards the bottom of the square tube steel from one end of the tube opening. It also includes an angle iron component. The two corner plates of the angle iron component are respectively provided with screw holes. The triangular tube steel has corresponding screw holes on the tube walls on both sides of the relief groove. The triangular tube steel is sleeved on the outer end of the inclined beam from the tube opening at the relief groove. The bottom of the support plate of one end of the support inclined roller shaft fixed on the inclined beam is embedded in the relief groove and adjacent to the square tube steel. The angle iron component covers the relief groove and the two corner plates are respectively abutted against the corresponding tube walls of the triangular tube steel on both sides of the relief groove. After being screwed through the screw holes of both by fastening bolts, it abuts against the inclined beam.

[0011] Furthermore, the support plate is sandwiched between the bottom of the clearance groove and the angle iron component.

[0012] Furthermore, the opening of the triangular tube steel away from the clearance groove is sealed by a welded cover plate.

[0013] This invention can effectively solve the problem of belt misalignment in the load-bearing section. It has a simple structure and can be quickly disassembled and assembled, making it easy to install and maintain. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] As shown in the figure, the idler mechanism of the bearing section of this utility model adopts a V-shaped structure, including a support frame 1 and a V-shaped idler frame 2. The V-shaped idler frame 2 consists of a horizontal crossbeam 21 in the middle and inclined beams 22 on both sides. A horizontal roller 51 with its rotation axis parallel to its extension direction is supported on the crossbeam 21, and an inclined roller 52 with its rotation axis parallel to its extension direction is supported on each side of the inclined beam 22. The support frame 1 is fixedly installed on the conveyor belt frame through connectors at both ends. The V-shaped idler frame 2 and the support frame 1 are rotatably connected through a rotating assembly 3. Specifically, the rotating assembly 3 is located between the middle of the crossbeam 21 of the idler frame 2 and the middle of the support frame 1.

[0024] At the outer end of the inclined beam 22 on each side, a straightening side vertical roller 6 and a straightening upper horizontal roller 7 are respectively arranged. Specifically,

[0025] The rotation axis of the straightening roller 6 is perpendicular to the rotation axis of the inclined roller 52 on the same side. The rotation axes of the two straightening rollers 6 are located in the same vertical plane. The vertical plane where the rotation axes of the two straightening rollers 6 are located is parallel to the vertical plane where the rotation axes of the two inclined rollers 52 are located. Most of the roller body 61 of the straightening roller 6 is higher than the highest point of the roller body surface of the inclined roller 52. At the same time, the roller body of the straightening roller 6 is located between the two ends of the roller body axis of the inclined roller 52 and is relatively close to the outer end.

[0026] The rotation axis of the upper horizontal roller 7 is located directly above the rotation axis of the inclined roller 52 on the same side, and both are in the same vertical plane. The rotation axis of the upper horizontal roller 7 is parallel to the rotation axis of the horizontal roller 51. The projections of the upper part of the roller body 71 of the upper horizontal roller 7 on the same side, the upper part of the roller body 61 of the vertical roller 6 on the side of the correction, the lower part of the roller body of the vertical roller 6 on the side of the correction, and the outer end of the inclined roller 52 in the direction of conveyor belt travel (e.g., Figure 1 As shown, the three components are intersecting, and on the projection surface, they are connected end to end to form a hook-shaped correction structure. Therefore, when the conveyor belt deviates to the left (or right) along the forward direction, the left (or right) correction side vertical roller 6 provides lateral rolling correction and constraint to the right (or left), while the correction upper horizontal roller 7 located directly above the inclined roller 52 provides rolling downward correction and constraint. The two work together to better correct the left and right and up and down of the conveyor belt in the carrying section, and can more effectively prevent the extreme condition of the conveyor belt coming off.

[0027] Furthermore, combined with Figure 1 and Figure 2 As shown, it also includes a limiting plate 4. The bottom of the limiting plate 4 is fixed to the support frame 1. The crossbeam 21 of the V-shaped idler frame 2 is made of angle iron and its cross-section is a triangular flared mouth with the opening facing downward. The limiting plate 4 extends vertically upward and its top extends into the opening below the crossbeam 21. Chamfered edges 41 are formed on both sides of the top of the limiting plate 4. Each chamfered edge 41 restricts the rotation angle of the crossbeam 21 around the axis of the rotating assembly 3 by abutting the corresponding corner plate of the crossbeam 21 made of angle iron. In this way, together with the straightening side vertical roller 6 and the straightening upper horizontal roller 7, it can better correct and straighten the conveyor belt in the left and right and up and down, and can more effectively prevent the extreme working condition of the conveyor belt coming off.

[0028] Furthermore, this utility model also provides a quick-installation and quick-disassembly structure for the straightening side vertical roller 6 and the straightening upper horizontal roller 7, so as to... Figure 3 Taking the cross-sectional view of the installation structure of the upper horizontal roller 7 shown as an example, the roller shaft 710 of the upper horizontal roller 7 can be inserted into the pipe hole 720 of the stepped mounting tube 72. The outer tube surface of the stepped mounting tube 72 is divided into a thick tube section 722 and a thin tube section 721, and an annular shoulder 723 is formed at the junction of the two. A threaded hole is opened on the thick tube section 722. The fastening bolt 73 is screwed through the threaded hole and abuts against the roller shaft 710, thereby fixing the roller shaft 710 of the upper horizontal roller 7 to the stepped mounting tube 72, and can be easily disassembled. The thin tube section 721 passes through the through hole 701 on the two side plates of the square tube steel 70, and is limited by the annular shoulder 723 abutting against one side plate and fixed to the stepped mounting tube 72 and the square tube steel 70 by welding.

[0029] In one embodiment, such as Figure 1 As shown, square tube steel (70, 60) is welded and fixed to inclined beam 22, so that the upper horizontal roller 7 and the side vertical roller 6 of the correction are respectively installed on inclined beam 22; the square tube steel 70 has a support groove on one side plate surface, which is used to insert and support the outer end of the inclined roller 52 shaft, that is, it also serves as a support plate for one end of the inclined roller 52 shaft.

[0030] In another embodiment, the present invention provides a support plate 221 (such as...) Figure 6 How to upgrade and modify the old equipment (as shown) by adding a corrective upper horizontal rod 7, such as... Figures 4 to 6 As shown, the bottom of the square tube steel 70 is welded and fixed to the tube wall at the apex of the triangular tube steel 8. The tube wall at the apex of the triangular tube steel 8 has a relief groove 82 extending towards the bottom of the square tube steel 70, starting from one end of the tube opening. It also includes an angle iron component 9, with screw holes on both sides of the angle iron component 9. The triangular tube steel 8 has corresponding screw holes 84 on the tube walls on both sides of the relief groove 82. The triangular tube steel 8 is fitted onto the outer end of the inclined beam 22 through the opening at the relief groove 82, and is fixed to the inclined beam 22 as a support. The bottom of the support plate 221 at one end of the roller 52 is embedded in the clearance groove 82 and adjacent to the square tube steel 70. The angle iron component 9 covers the clearance groove 82 and the two side angle plates are respectively abutted against the corresponding tube walls of the triangular tube steel 8 on both sides of the clearance groove 82. After being screwed through the bolt holes of the two, they abut against the inclined beam 22, thereby fixing the triangular tube steel 8 to the inclined beam 22. Then, the correction upper horizontal bar 7 installed on the square tube steel 70 is installed on the inclined beam 22, realizing the transformation and upgrading without discarding the old equipment and saving costs.

[0031] Preferably, the support plate 221 is sandwiched between the bottom of the clearance groove 82 and the angle iron component 9 to prevent it from coming off.

[0032] Preferably, the opening of the triangular tube steel 8 away from the clearance groove 82 is sealed by a welded cover plate 81, which provides a certain dustproof effect.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
