Description

TECHNICAL FIELD

[0001] The utility model relates to a conveyor technical field, concretely relates to a ring belt conveyor guide wheel limiting device and ring belt conveyor. BACKGROUND

[0002] The ring belt conveyor is a special belt conveyor, which is developed to meet the special structure of the ring and multiple bulk material openings of the sintering ring cooler. It is powered by two reduction motors at the head and tail, and the heat-resistant belt on the cylinder is driven by the cylinder connected with the reduction motor, so that the sintering bulk material falling on the heat-resistant belt is collected and transported from various places to the unloading point. During the whole process, the sintering bulk material is kept on the heat-resistant belt, ensuring the continuity and stability of transportation. Due to its good sealing performance and stable operation during transportation, it can effectively improve the production efficiency and is widely used.

[0003] In the existing ring belt conveyor, the heat-resistant belt often swings up and down when the guide wheel runs on the guide rail due to the combined action of its own gravity, the pressure of the material on the heat-resistant belt, the supporting force of the lower roller and the centripetal force when the heat-resistant belt runs. The up-and-down swing of the heat-resistant belt increases the wear of the guide rail, and the heat-resistant belt is also prone to friction with the upper and lower guide rails, increasing the running resistance of the ring belt conveyor, affecting the operation efficiency of the conveyor, and greatly reducing the service life of the heat-resistant belt. In addition, when the heat-resistant belt swings up and down with the guide wheel, it will increase the sliding of the sintered bulk material, causing equipment failure and dust raising.

DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of the present application, the present application will be described more fully below, and the preferred embodiments of the present application are given. However, the present application can be realized in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0031] Example 1:

[0032] Referring to Figures 1-5The embodiment provides a ring belt conveyor, which comprises a frame body 2, a ring belt 3, an upper supporting roller group 4, a lower supporting roller group 5, a guide roller group 6, a ring track group 7, a driving device 8 and a ring belt conveyor guide roller limiting device 100, the frame body 2 is arranged in a ring shape with an opening, the upper supporting roller group 4 and the lower supporting roller group 5 are arranged on the frame body 2 and are distributed in an upper and lower mode, a conveying part of the ring belt 3 is supported on the upper supporting roller group 4, a return part of the ring belt 3 bypasses the driving device 8 and is supported on the lower supporting roller group 5; the ring track group 7 is arranged in a ring shape with an opening, the ring track group 7 is arranged in two groups, one group of the ring track group 7 is arranged corresponding to the conveying part of the ring belt 3, and the other group of the ring track group 7 is arranged corresponding to the return part of the ring belt 3, each group of the ring track group 7 comprises two ring tracks 71, the two ring tracks 71 are fixedly connected to the frame body 2 in an upper and lower mode, and the two ring tracks 71 have a gap 72 allowing the ring belt 3 to pass; the guide roller group 6 comprises two guide rollers, the two guide rollers are coaxially arranged on the outer edge of the ring belt 3, and the two guide rollers are arranged on the upper and lower sides of the ring belt 3 respectively, the two guide rollers are laterally supported on the upper and lower ring tracks 71 respectively, and the guide roller group 6 is arranged in multiple groups along the outer edge of the ring belt 3 at equal intervals; the driving device 8 is installed on the frame body 2 and is used for driving the ring belt 3 to move; the ring belt conveyor guide roller limiting device 100 is installed on the ring track group 7, and the ring belt conveyor guide roller limiting device 100 is arranged corresponding to the ring track group 7 one by one.

[0033] It can be known that the driving device 8 drives the ring belt 3 to operate, so that the conveying end of the ring belt 3 continuously conveys materials along the ring shape with an opening, the materials falling on the machine above the ring belt 3 fall on the ring belt 3, and the falling materials are conveyed along the ring belt 3 to one end of the frame body 2 and are uniformly output and collected from the one end of the frame body 2. In the operation process, the upper supporting roller group 4 supports the conveying part of the ring belt 3 through a plurality of supporting rollers, the lower supporting roller group 5 supports the return part of the ring belt 3 through a plurality of supporting rollers, and the guide roller and the ring belt 3 are deformed downward under the action of gravity and the pressure of the materials in the operation process of the ring belt 3. Therefore, the guide roller group 6 is limited by the limiting device, so that the guide roller and the ring belt 3 are prevented from being deformed downward under the action of gravity, and the generation of shaking is relieved.

[0034] Further, the driving device 8 comprises a head driving roller 81 and a tail driving roller 82, the head driving roller 81 is arranged at the first end of the frame body 2, the tail driving roller 82 is arranged at the second end of the frame body 2, and the ring belt 3 is arranged around the head driving roller 81 and the tail driving roller 82.

[0035] It can be known that the head driving roller 81 drives the annular belt 3 to move through friction when rotating, and the head driving roller 81 and the tail driving roller 82 are used to change the direction of the annular belt 3, so that the annular belt 3 is folded back by 180 degrees from the conveying section around the head driving roller 81 to the return section, and is folded back by 180 degrees from the return section around the tail driving roller 82 to the conveying section, so as to form a compact annular circulation.

[0036] Further, the annular belt 3 is arranged with a baffle 31, and the baffle 31 is arranged on the annular belt 3 to block the material on the conveying part of the annular belt 3.

[0037] It can be known that during the operation of the annular belt 3, the material distributed above the annular belt 3 moves in a circular motion along the annular belt 3. When the material moves in a circular motion, it will move radially outward along the annular belt 3 due to the centrifugal force generated by inertia when the centrifugal force is greater than the static friction. The material will scatter outside the frame 2. By arranging the baffle 31, the material is blocked to prevent scattering.

[0038] Embodiment 2:

[0039] Referring to Figures 6-8 The embodiment provides a guide wheel limiting device 100 of an annular belt conveyor, which comprises limiting bars 1 arranged on two annular tracks 71, the limiting bars 1 comprising upper limiting bars 11 and lower limiting bars 12, the upper limiting bars 11 being fixedly connected to the outer sides of the upper annular tracks 71, and the lower limiting bars 12 being fixedly connected to the outer sides of the lower annular tracks 71, and the upper limiting bars 11 and the lower limiting bars 12 forming limiting grooves 13 at equal intervals.

[0040] It should be noted that the guide wheel limiting device 100 of the annular belt conveyor is installed on the annular belt conveyor in embodiment 1, the guide wheel set 6 is limited by the limiting grooves 13, and the guide wheel set 6 is installed on the annular belt 3, so that the guide wheel set 6 and the annular belt 3 are limited by the upper limiting bars 11 and the lower limiting bars 12.

[0041] It can be known that by arranging the upper limiting bars 11 and the lower limiting bars 12 on the annular guide rail, the upper limiting bars 11 and the lower limiting bars 12 are arranged protruding from the annular guide rail, thereby limiting the guide wheels, preventing the guide wheels from tilting up and down, and further preventing the annular belt 3 from tilting up and down, thereby improving the stability of the annular belt 3 during operation, preventing the annular belt 3 from scratching the frame 2 or rubbing against the annular guide rail during operation, improving the service life of the belt, and further improving the stability of the belt during operation, reducing the resistance of the belt during operation, reducing energy consumption, and reducing dust generated during operation of the annular belt 3.

[0042] Further, the lower end of the upper blocking strip 11 is provided with a first blocking boss 111, the upper end of the lower blocking strip 12 is provided with a second blocking boss 121, and the limiting groove 13 is located between the first blocking boss 111 and the second blocking boss 121.

[0043] It can be known that the thickness of the upper blocking strip 11 and the lower blocking strip 12 cannot be too thick, which is not easy to process, and when the thickness of the upper blocking strip 11 and the lower blocking strip 12 is relatively thin, the limiting effect of the upper blocking strip 11 and the lower blocking strip 12 on the guide wheel is limited, and the upper blocking strip 11 and the lower blocking strip 12 cannot well limit the guide wheel. However, through the arrangement of the first blocking boss 111 and the second blocking boss 121, the height of the limiting of the guide wheel is increased, and the limiting effect of the guide wheel is improved.

[0044] Further, a connecting hole 122 is arranged on the lower blocking strip 12 along the radial direction of the annular track 71, and the connecting hole 122 penetrates the lower blocking strip 12.

[0045] Specifically, the connecting hole 122 can be a plug welding hole for plug welding, can be a bolt connection hole for bolt connection, or can be a riveting hole for riveting.

[0046] Taking the plug welding hole as an example, the lower blocking strip 12 is fixedly connected to the annular track 71 by welding. If welding is performed on the side close to the guide wheel, an inclined weld will be formed on the side close to the guide wheel, which will weaken the limiting effect on the guide wheel. If welding is performed on the side of the lower blocking strip 12 away from the guide wheel, the lower blocking strip 12 close to the guide wheel is prone to warping during use, resulting in poor limiting effect on the guide wheel. By arranging the connecting hole 122 on the lower blocking strip 12 and welding in the connecting hole 122, the lower blocking strip 12 can be stably connected to the annular track 71. In addition, arranging the connecting hole 122 in the middle of the lower blocking strip 12 can effectively prevent the lower blocking strip 12 from warping during use.

[0047] Further, a plurality of connecting holes 122 are arranged, and the plurality of connecting holes 122 are arranged at intervals along the length direction of the lower blocking strip 12.

[0048] It can be known that by arranging a plurality of connecting holes 122 at intervals and welding in the connecting holes 122, the lower blocking strip 12 can be stably and fixedly connected to the annular track 71, and the lower blocking strip 12 is prevented from falling off.

[0049] Further, the two adjacent connecting holes 122 are arranged in an up-and-down staggered manner.

[0050] It can be known that if the connecting hole 122 is arranged on the side close to the guide wheel, the side of the lower fender 12 far from the guide wheel is easy to be warped, if the connecting hole 122 is arranged on the side far from the guide wheel, the side of the lower fender 12 close to the guide wheel is easy to be warped, by staggering the arrangement of the two adjacent connecting holes 122, the warping of the lower fender 12 is prevented.

[0051] Further, the connecting hole 122 is a circular hole, and the diameter of the connecting hole 122 is controlled between 5mm and 10mm.

[0052] It can be known that by controlling the diameter of the connecting hole 122 between 5mm and 10mm, on the one hand, it is convenient to use the drill with the specification between 5mm and 10mm for construction, on the other hand, it is convenient to weld, the connecting hole 122 is too small to be inconvenient for welding, and it is easy to form a false weld, and the connecting hole 122 is too large, on the one hand, it needs longer welding time, and on the other hand, it greatly weakens the overall strength of the lower fender 12.

[0053] Further, the distance between the two adjacent connecting holes 122 is controlled between 10cm and 30cm.

[0054] It can be known that the distance is too long, and the connecting stability between the loop track 71 and the lower fender 12 is poor, and the distance is too short, and the construction cost is increased.

[0055] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, for the person skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
