Description

Technical Field

[0001] The utility model belongs to the technical field of tubular belt supports, and mainly relates to a device capable of quickly replacing bottom rollers of a tubular belt. Background Art

[0002] The sintering machine's feeding system is responsible for conveying the mixed material to the sintering machine's ore chute and is a crucial piece of equipment in the sintering system. The existing tubular belt conveyor system for the mixed material is approximately 700 meters long per side. The bottom rollers of the belt have shown significant wear and tear due to long service life. Due to the belt's long, cylindrical shape, replacing the bottom rollers requires lifting the belt with a guide chain, which is time-consuming and labor-intensive.

[0003] The Chinese patent document with authorization announcement number CN207844268U discloses a belt conveyor buffer roller frame, which relates to the field of buffer rollers. Two spring buffer devices are connected between the upper roller frame and the lower roller frame. The spring buffer device includes a cylindrical upper protrusion with an opening at the lower end vertically welded to the bottom of the upper roller frame, a lower protrusion welded to the top of the lower roller frame and symmetrical with the upper protrusion in structure and position, and a telescopic hose connected between the upper protrusion and the lower protrusion. A spring is vertically placed in the lower protrusion, and the pin is also vertically welded to the bottom of the upper roller frame and inserted into the spring. A through hole is opened at the bottom of the lower protrusion, and a guide tube is provided below the through hole, which is vertically welded to the bottom of the lower roller frame and connected to the through hole. The bottom of the guide tube is connected to an air storage cavity, and the anti-tilt channel steel is also included. The anti-tilt channel steel and the pad are fixed to the lower roller frame by bolts.

[0004] Although the belt conveyor buffer roller frame can support the rollers, the application range of the belt conveyor buffer roller frame is relatively small due to the limitation of the roller group. Utility Model Content

[0005] The utility model provides a device for quickly replacing bottom rollers of a tubular belt, so as to solve the problem that the application range of roller frames in the prior art is small.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] A device for quickly replacing bottom rollers of a tubular belt comprises a support frame and a roller assembly slidably mounted on the support frame in an up-and-down direction, wherein the support frame is provided with a linear drive member for driving the roller assembly to move in an up-and-down direction;

[0008] The roller assembly includes a slide rail mounted on a support frame for sliding in the up and down directions, and two mounting frames that can slide relative to each other along the axial direction on the slide rail and are arranged opposite to each other. The slide rail extends in the horizontal direction. Side rollers are rotatably mounted on the two mounting frames. The two side rollers are arranged opposite to each other so that the interval between the two side rollers changes when the two mounting frames slide relative to each other on the slide rail. A bottom roller is hinged between the two mounting frames. The two side rollers and the bottom roller form a support area for the tubular belt.

[0009] The invention has the following beneficial effects: the two mounting frames slide relative to each other on the slide rail to change the interval between the two side rollers so that the interval can be suitable for tubular belts of different diameters; at the same time, the linear drive member can drive the slide rail to move in the up and down directions so that the device can be suitable for tubular belts of different heights.

[0010] Furthermore, a mounting seat is rotatably mounted on the bottom edge roller, and the mounting seat is hinged to the two mounting frames respectively, and the hinge axis is perpendicular to the extension direction of the slide rail and extends horizontally.

[0011] Furthermore, the rotation axis of the bottom roller is consistent with the extension direction of the slide rail, and the rotation axes of the two side rollers are coplanar with the rotation axis of the bottom roller.

[0012] The invention has the following beneficial effects: the rotation axis of the bottom edge roller is perpendicular to the moving direction of the tubular belt, so that the two side rollers and the bottom edge roller can more easily support the tubular belt and also make the tubular belt more easily move.

[0013] Furthermore, the support frame has a sliding guide plane that fits with the side of the slide rail, and the slide rail slides up and down along the sliding guide plane. Both of the mounting frames are provided with limit blocks, and the limit blocks have a limit plane that fits with the sliding guide plane to maintain the vertical state of the mounting frame.

[0014] Furthermore, at least two rollers are rotatably mounted on the same side of the slide rail, the rotation axes of which are perpendicular to the extension direction of the slide rail, and the two rollers are located on both sides of the support frame;

[0015] The support frame is provided with a limiting rolling plane respectively fitted with the two rollers to maintain the horizontal state of the slide rail.

[0016] Furthermore, the linear drive component has a fixed end and a telescopic end, the fixed end is placed on the support frame, the telescopic end presses the slide rail, and the telescopic end telescopes in the up and down directions to drive the slide rail to move along the up and down directions.

[0017] Furthermore, the support frame includes a base and at least four limiting members fixed to the base, each of the limiting members has the sliding guide plane, and the limiting members are arranged relative to each other so that the two sliding guide planes form a sliding area for the slide rail to move, and the slide rail slides within the at least two sliding areas;

[0018] Each limiting member has a limiting rolling plane that fits with the corresponding roller.

[0019] The invention has the following beneficial effects: the sliding guide plane extends vertically, and thus the enclosed sliding area limits the moving direction of the slide rail, so that the slide rail can only move in the up and down directions.

[0020] Furthermore, the slide rail has a dovetail groove, and the extension direction of the dovetail groove is consistent with the extension direction of the slide rail;

[0021] Two dovetail blocks are slidably mounted in the dovetail groove, and the two dovetail blocks are hinged to corresponding mounting brackets respectively, so that the two mounting brackets can slide on the slide rail.

[0022] The invention has the following beneficial effects: the cooperation between the dovetail groove and the dovetail block can prevent the mounting frame from sliding off the slide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following describes various non-limiting embodiments of the present invention. The numbers of any elements in the accompanying drawings are for illustrative purposes only and are not intended to be limiting. Any nomenclature is provided for distinction only and does not have any limiting meaning. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with one another unless there is a conflict.

[0037] like Figure 1 、 Figure 2 As shown, a device for quickly replacing bottom rollers of a tubular belt comprises a support frame 1 and a roller assembly 3 slidably mounted on the support frame 1 in the vertical direction. The support frame 1 is provided with a linear drive member 4 for driving the roller assembly 3 in the vertical direction. In this embodiment, the linear drive member 4 is a jack.

[0038] In other embodiments, the linear drive member 4 is a cylinder or an electric push rod.

[0039] like Figure 3-Figure 5As shown, the roller assembly 3 includes a slide rail 2 that slides vertically on a support frame 1, and two mounting frames 5 that are arranged opposite each other and can slide relative to each other along the axial direction of the slide rail 2. The slide rail 2 extends horizontally, and side rollers 6 are rotatably mounted on each mounting frame 5. The two side rollers 6 are arranged relative to each other so that when the two mounting frames 5 slide relative to each other on the slide rail 2, the spacing between the two side rollers 6 can be changed, and the extension direction of the axes of the two side rollers 6 can also be changed. A bottom roller 7 is hingedly connected between the two mounting frames 5. The two side rollers 6 and the bottom roller 7 form a support area 12 for the tubular belt. When the tubular belt is placed in the support area 12, the two side rollers 6 and the bottom roller 7 will contact the tubular belt, thereby clamping and supporting the tubular belt in three directions. The height of the roller assembly 3 can also be adjusted by a linear drive 4 to accommodate tubular belts of different heights, expanding the maintenance range of the rollers.

[0040] The two mounting frames 5 slide relative to each other on the slide rail 2 to change the interval between the two side rollers 6 so that the interval can be suitable for tubular belts of different diameters, thereby expanding the scope of application of the device. At the same time, the bottom rollers 7 can support tubular belts of different diameters; at the same time, the linear drive member 4 can drive the slide rail 2 to move in the up and down directions so that the device can be suitable for tubular belts of different heights.

[0041] like Figure 3 、 Figure 4 、 Figure 9 As shown, a mounting base 8 is rotatably mounted on the bottom idler 7. Mounting base 8 is hinged to the two mounting brackets 5, with the hinge axis extending horizontally and perpendicular to the extension direction of the slide rail 2. The rotation axis of the bottom idler 7 is aligned with the extension direction of the slide rail 2, and the rotation axes of the two side idlers 6 are coplanar with the rotation axis of the bottom idler 7. The rotation axis of the bottom idler 7 is perpendicular to the direction of movement of the tubular belt. This makes it easier for the two side idlers 6 and the bottom idler 7 to support the tubular belt and facilitate its movement.

[0042] like Figure 4 、 Figure 7 、 Figure 8 As shown, the support frame 1 has a sliding guide plane 13 that is in contact with the side of the slide rail 2, and the slide rail 2 slides up and down along the sliding guide plane 13. The two mounting frames 5 are each provided with a limit block 9, and the limit block 9 has a limit plane 18 that is in contact with the sliding guide plane 13. When the slide rail 2 slides in the up and down direction, the limit block 9 always contacts the sliding guide plane 13, thereby maintaining the vertical state of the mounting frames 5 and preventing the two mounting frames 5 from deviating when supporting the tubular belt.

[0043] like Figure 4 、 Figure 6As shown, two rollers 10 are rotatably mounted on the same side of the slide rail 2. The rotation axes of the two rollers 10 are perpendicular to the extension direction of the slide rail 2. The two rollers 10 are located on either side of the support frame 1, so that the two rollers 10 just sandwich the support frame 1. The support frame 1 has a limiting rolling surface 14 that is respectively in contact with the two rollers 10. The limiting rolling surface 14 extends vertically, thereby maintaining the horizontal state of the slide rail 2.

[0044] In other embodiments, more than three rollers 10 are rotatably mounted on the same side of the slide rail 2 , and the more than three rollers 10 are respectively fitted with the limiting rolling planes 14 on the corresponding sides to better maintain the horizontal state of the slide rail 2 .

[0045] like Figure 3-Figure 5 As shown, the linear drive member 4 has a fixed end and a telescopic end. The fixed end is placed on the support frame 1, and the telescopic end presses against the slide rail 2. The telescopic end extends and retracts in the vertical direction to drive the slide rail 2 to move in the vertical direction. The linear drive member 4 in this embodiment is placed on the support frame 1 and can be removed when it is not needed.

[0046] In other embodiments, the linear drive member 4 is fixed to the support frame 1 and cannot be removed.

[0047] like Figure 4 、 Figure 7 As shown, the support frame 1 includes a base and four limiting members 16 fixed to the base. Each limiting member 16 has a sliding guide plane 13. The limiting members 16 are arranged in pairs so that the two sliding guide planes 13 enclose a sliding area 17 within which the slide rail 2 moves. The slide rail 2 slides within the two sliding areas 17. Each limiting member 16 has a limiting rolling surface 14 that engages with the corresponding roller 10. The sliding guide planes 13 extend vertically, so the enclosed sliding area 17 restricts the movement of the slide rail 2, forcing it to move only in the up and down directions.

[0048] In other implementations, the number of the limiting members 16 is five or more, preferably an even number, such as six, eight, or ten, etc.

[0049] like Figure 6 As shown, the slide rail 2 has a dovetail groove 15 extending in the same direction as the slide rail 2. Two dovetail blocks 11 are slidably mounted within the dovetail groove 15. The two dovetail blocks 11 are hingedly connected to corresponding mounting brackets 5, allowing the two mounting brackets 5 to slide on the slide rail 2. The cooperation between the dovetail groove 15 and the dovetail blocks 11 prevents the mounting brackets 5 from sliding off the slide rail 2.

[0050] The working process of this utility model is as follows:

[0051] In the initial state, the interval between the two side rollers 6 in this device is large. In the process of the linear drive 4 driving the slide rail 2 to move upward, when the bottom roller 7 contacts the tubular belt, the two side rollers 6 will move toward the tubular belt under the action of the linear drive 4 until they contact the tubular belt. After that, the linear drive 4 will no longer run, thereby completing the support of the tubular belt and facilitating the subsequent maintenance of the rollers.

[0052] Since the interval between the two side rollers 6 can be changed, the device can be applied to support tubular belts of various diameters, thereby expanding the scope of application of the device.
