Abstract
Description
Technical Field
[0001] The utility model relates to a belt conveying technology, belongs to the field of coal mine transportation, and particularly relates to a cleaning roller device. Background Art
[0002] Belt conveyors are widely used in the bulk material transportation industry. Taking the belt conveyor for coal transportation as an example, the main structure of the belt conveyor includes multiple sets of roller devices arranged along the conveying direction, and a belt wrapped around the outer side of the roller device to form a closed loop structure.
[0003] When a belt conveyor runs for a long time, due to belt wear, dust or splashing of conveyed materials, there will be attachments on the surface of the roller 10. This attachment will change the local diameter of the roller 10, and thus affect the tension distribution of the belt during the conveying process. That is, when the attachments are unevenly distributed on the roller 10, the tension on both sides of the belt will be unbalanced, thereby generating lateral force and causing the belt to deviate.
[0004] At present, the commonly used method for cleaning the attachments on the surface of the roller 10 is to use a cleaning roller brush. For example, a cleaning roller brush in contact with the roller 10 is set under the roller 10, and the cleaning roller brush is driven to clean the roller 10. However, there are the following problems: the cleaning roller brush is always in a working state. When there is no attachment on the surface of the roller 10 or the belt is not deviated, the cleaning roller brush will cause ineffective cleaning, that is, continuous cleaning by the cleaning roller brush will cause the cleaning roller brush to wear and the cleaning ability will be reduced; and when there is attachment on the surface of the roller 10, the cleaning roller brush cannot adjust the cleaning force on the roller 10 according to the degree of deviation. Summary of the Invention
[0005] The utility model aims to provide a cleaning roller device with a simple and compact structure, which can achieve efficient cleaning of the rollers when the belt deviates, and can adjust the cleaning force according to the degree of deviation, so as to achieve better cleaning effect.
[0006] To achieve the above purpose, the cleaning roller device includes:
[0007] rollers;
[0008] The brush wheel is rotatably mounted on the supporting plate and is driven to be located on one side of the roller to clean the surface of the roller;
[0009] A pair of vertical rollers, each located at the end of the roller and mounted on one end of the slewing arm, with the other end of the slewing arm fixed on the support shaft;
[0010] The support shaft is arranged in a rotating manner and is subjected to torsion so that the vertical roller is close to the edge of the belt;
[0011] An adjusting component, comprising an adjusting disk and a connecting assembly;
[0012] An adjusting disk is fixed on the supporting shaft and is provided with an arc track with variable height;
[0013] The connecting component has one end in contact with the arc track and the other end is affected by the change of the arc track so that the distal end of the brush wheel is close to the roller.
[0014] In some embodiments, the connecting component is an adjustment rod;
[0015] The middle part of the adjusting rod is rotatably mounted on the fixing seat, one end of the adjusting rod is provided with a first supporting rod in contact with the adjusting disk, and the other end of the adjusting rod is provided with a second supporting rod movably connected with the supporting plate.
[0016] Furthermore, each adjusting rod is acted upon by an elastic push rod so that the first support rod is always in contact with the adjusting disk.
[0017] In some embodiments, the connecting assembly is a first hydraulic rod and a second hydraulic rod;
[0018] The piston output end of the first hydraulic rod is in contact with the adjustment disk, and the piston output end of the second hydraulic rod is movably connected to the supporting plate;
[0019] The inner cavity of the first hydraulic rod away from the output end thereof is communicated with the inner cavity of the second hydraulic rod away from the output end thereof.
[0020] Furthermore, a spring is provided in the inner cavity of the first hydraulic rod away from the output end thereof.
[0021] In some embodiments, the support shaft is rotatably mounted on the support base plate and is provided with a torsion spring;
[0022] One end of the torsion spring is connected to the shaft shoulder of the support shaft, and the other end is connected to the support base plate.
[0023] Furthermore, a limit block for limiting the rotation angle of the support shaft is provided on the support base plate.
[0024] In some embodiments, the brush wheel is an inner brush and an outer brush provided on a brush shaft;
[0025] The inner brush is harder than the outer brush and has relatively more bristles.
[0026] In some embodiments, one end of the brush wheel is connected to a drive motor or a transmission assembly;
[0027] When it is a transmission assembly, the transmission assembly has a first gear, a second gear, a first moving wheel, and a second moving wheel;
[0028] The first gear is fixed on the shaft where the roller is located and is meshed with the second gear;
[0029] The first moving wheel rotates coaxially with the second gear and is connected to the second moving wheel via a transmission belt wound around the outside of the first moving wheel, and the transmission belt is elastically tensioned;
[0030] The second moving wheel is fixed on the end side of the brush wheel.
[0031] Compared with the prior art, the cleaning roller device of the present invention brings the vertical roller close to the edge of the belt due to the torsion of the support shaft, and one end of the connecting component contacts the arc track, and the other end is affected by the change of the arc track to bring the distal end of the brush wheel close to the roller. Therefore, when the belt deviates, the vertical roller drives the adjusting disk on the support shaft to rotate through the rotating arm. Under the action of the connecting component, the distal end of the brush wheel is close to the roller, so that the roller can be cleaned efficiently when the belt deviates. Moreover, when the degree of deviation is greater, the distal end of the brush wheel is closer to the roller, and the cleaning force can be adjusted according to the degree of deviation, so as to achieve better cleaning effect.
[0032] Since the brush wheel consists of an inner brush and an outer brush arranged on the brush shaft, in the initial state, the outer brush contacts the surface of the roller, and the cleaning intensity is relatively small, which can clean smaller attachments such as dust and avoid dust accumulation; when the belt deviates, the inner brush contacts the surface of the roller, and the cleaning intensity is relatively strong, which can clean direct and larger attachments such as material splashing and belt wear. Therefore, it can be used in different usage environments, avoiding the ineffective cleaning of traditional cleaning rollers and being more targeted;
[0033] Since the brush wheel is provided with a transmission assembly, the first gear on the roller transmits power to the second gear and the coaxially arranged first moving wheel, and then transmits power to the second moving wheel and the brush wheel through the transmission belt; the roller and the brush wheel are linked to avoid the addition of an additional drive motor, and the device is suitable for locations where it is inconvenient to use power.

[0046] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0047] like Figures 1 to 4 As shown, the cleaning roller device includes:
[0048] Roller 10;
[0049] The brush wheel 40 is rotatably mounted on the supporting plate 41 and is driven to be located on one side of the roller 10 for cleaning the surface of the roller 10;
[0050] A pair of vertical rollers 21, each of which is located at the end side of the roller 10 and is installed at one end of a rotating arm 22, and the other end of the rotating arm 22 is fixed to the support shaft 23;
[0051] The support shaft 23 is arranged to rotate and is subjected to torsion so that the vertical roller 21 is close to the edge of the belt;
[0052] An adjustment component having an adjustment disk 24 and a connecting assembly;
[0053] An adjusting disk 24 is fixed to the support shaft 23 and is provided with an arc-shaped track 241 of variable height;
[0054] The connecting component has one end in contact with the arc track 241 and the other end is affected by the change of the arc track 241 to move the distal end of the brush wheel 40 closer to the roller 10;
[0055] Specifically, the roller 10 is used to support the belt, and its axis is perpendicular to the conveying direction of the belt, and the axes at both ends are rotatably mounted on the support frame 11, which is the main supporting structure in the conveying mechanism;
[0056] The brush wheel 40 contacts the peripheral side of the roller 10 and is used to clean the surface of the roller 10. Preferably, the roller 10 is used to support the upper belt, and the brush wheel 40 is located below the roller 10;
[0057] The vertical roller 21 preferably has an axis perpendicular to the axis of the roller 10 and is used to limit the belt. That is, when the belt deviates, the belt will contact the vertical roller 21. As explained, the roller 10, the vertical roller 21, and the brush wheel 40 themselves can adopt existing structures.
[0058] The support shaft 23 has its lower end rotatably mounted on a sleeve via a bearing. The sleeve is fixed to the support base plate 30 via multiple bolts. In the initial state, the support shaft 23 is subjected to torsion, causing the vertical roller 21 on the slewing arm 22 to be in a certain position. This position ensures that the belt can contact the vertical roller 21 when it deviates. The slewing arm 22 is a rod structure.
[0059] The adjustment component is used to ensure that the vertical roller 21 and the brush wheel 40 respond to each other in a timely manner when the belt deviates, thereby adjusting the cleaning force of the brush wheel 40. The adjustment disk 24 is fixed to the support shaft 23, and the arc track 241 is arranged circumferentially. That is, as the support shaft 23 rotates, the arc track 241 at the same position changes in height, and this change is a smooth transition. One end of the connecting component contacts the arc track 241 and is affected by the arc track 241.
[0060] Example 1
[0061] In the initial state of use of the cleaning roller device, the support shaft 23 is subjected to elastic force so that one end of the rotating arm 22 is directed toward the belt, that is, the vertical roller 21 is close to the belt; the roller 10 normally supports and conveys the belt, the axis of the brush wheel 40 is parallel to the axis of the roller 10, and the brush on the brush wheel 40 contacts the roller 10 for cleaning. At this time, one end of the connecting component contacts the arc track 241;
[0062] As explained, in the initial state, the brush cleaning process can be used for dust removal, and its force is relatively small;
[0063] When the belt is used for a long time, due to belt wear, dust and other reasons, the surface of the roller 10 is covered with a lot of attachments and has strong adsorption. The initial brush cannot meet the cleaning effect. The roller 10 is partially enlarged due to the attachments, and the belt deviates.
[0064] Take the case where there are many attachments on the right side of the roller 10 and the belt deviates to the left as an example.
[0065] When the belt deviates to the left, it will contact the left vertical roller 21, and the left vertical roller 21 drives the rotating arm 22 to rotate, causing the support shaft 23 to rotate at a certain angle; the adjusting disk 24 fixed to the support shaft 23 rotates, and because one end of the connecting component is in contact with the arc track 241, when the adjusting disk 24 rotates, the connecting component is affected by the change of the arc track 241 and performs corresponding actions, so that the distal end (right end) of the brush wheel 40 is close to the roller 10. At this time, the distance between the right side of the brush wheel 40 and the roller 10 is reduced, the cleaning force is greater, and the cleaning force can be adjusted according to the degree of deviation, so the effect is better;
[0066] When the attachments on the right side of the roller 10 are cleaned, the support shaft 23 itself is subjected to the elastic torsion force to move the vertical roller 21 toward the conveying direction. Therefore, the vertical roller 21 will exert a lateral force to the right on the belt, and the belt returns to the initial conveying position.
[0067] Similarly, when there are more attachments on the left side of the roller 10 and the belt deviates to the right, the right vertical roller 21 rotates under the action of the belt deviation, and the adjustment disk 24 on the corresponding support shaft 23 rotates. Affected by the change of the arc trajectory 241, the corresponding connecting component performs corresponding action, so that the distal end (left end) of the brush wheel 40 is close to the roller 10. At this time, the distance between the left side of the brush wheel 40 and the roller 10 is reduced, and the cleaning force is greater.
[0068] like Figure 1 、 Figure 5 As shown, in some embodiments of the present invention, the connecting component is an adjustment rod 26;
[0069] The middle portion of the adjusting rod 26 is rotatably mounted on the fixed seat 31 , one end of which is provided with a first support rod 261 in contact with the adjusting disk 24 , and the other end of which is provided with a second support rod 262 movably connected to the supporting plate 41 ;
[0070] Furthermore, each adjusting rod 26 is acted upon by an elastic push rod 27 so that the first support rod 261 is always in contact with the adjusting disk 24;
[0071] In the initial state, the pair of adjustment rods 26 are tilted to ensure that the first support rod 261 at one end thereof is in contact with the arc track 241 and is located at the highest point of the arc track 241. The second support rod 262 at the other end of the adjustment rod 26 is movably connected to the support plate 41 so that the support plate 41 is in a horizontal state.
[0072] The second support rod 262 is rotatably mounted on the slider, and the slider slides along the length direction of the supporting plate 41;
[0073] The elastic push rod 27 can be a combination of an elastic member and a push rod, the purpose of which is to ensure that the first support rod 261 is always in contact with the arc track 241. As explained, since the adjustment rod 26 is arranged in the middle, the second support rod 262 is connected to the support plate 41. Under the action of the gravity of the support plate 41 and the brush wheel 40, the inclination of the adjustment rod 26 can be adjusted to ensure that the first support rod 261 is in contact with the arc track 241.
[0074] Example 2
[0075] When the belt deviates to the left and the left adjustment disk 24 rotates, the corresponding adjustment rod 26 rotates counterclockwise under the action of the left arc track 241, that is, the right end moves upward and drives the right support plate 41 to rise, so that the right side of the brush wheel 40 is close to the roller 10, increasing the force acting on the right side of the roller 10, so that the cleaning effect is better;
[0076] When the belt deviates to the right and the right adjustment disk 24 rotates, under the action of the right arc track 241, the corresponding adjustment rod 26 rotates clockwise, that is, the left side moves upward and drives the left support plate 41 to rise, so that the left side of the brush wheel 40 is close to the roller 10, increasing the force acting on the left side of the roller 10, so that the cleaning effect is better.
[0077] like Figure 1 、 Figure 6 As shown, in some embodiments of the present invention, the connecting assembly is a first hydraulic rod 51 and a second hydraulic rod 52;
[0078] The piston output end of the first hydraulic rod 51 contacts the adjustment plate 24, and the piston output end of the second hydraulic rod 52 is movably connected to the support plate 41;
[0079] The inner cavity of the first hydraulic rod 51 away from the output end thereof is communicated with the inner cavity of the second hydraulic rod 52 away from the output end thereof;
[0080] Furthermore, a spring 53 is provided in the inner cavity of the first hydraulic rod 51 away from the output end thereof;
[0081] In the initial state, the piston output end of the first hydraulic rod 51 is located at the highest point of the arc track 241, and the piston output end of the second hydraulic rod 52 is movably connected to the support plate 41 so that the support plate 41 is in a horizontal state;
[0082] The first hydraulic rod 51 and the second hydraulic rod 52 have the same structure and specifications, and their lower inner cavities can be connected to each other through an oil pipe, the purpose of which is to ensure that the two are linked to each other;
[0083] The spring 53 is located in the lower inner cavity of the first hydraulic rod 51. Its purpose is not only to keep the first hydraulic rod 51 in contact with the arc track 241 at all times, but also to return oil to keep the support plate 41 in a horizontal initial state when the belt is not deviating.
[0084] Example 3
[0085] When the belt deviates to the left and the left adjustment disk 24 rotates, the left first hydraulic rod 51 is compressed under the action of the left arc track 241, and the high-pressure oil is transported from the lower inner cavity of the left first hydraulic rod 51 to the lower inner cavity of the corresponding second hydraulic rod 52. The piston output end of the second hydraulic rod 52 moves upward, driving the right support plate 41 to rise, so that the right side of the brush wheel 40 is close to the roller 10, increasing the force acting on the right side of the roller 10, so that the cleaning effect is better;
[0086] When the belt deviates to the right and the right adjusting disk 24 rotates, the right first hydraulic rod 51 is compressed under the action of the right arc track 241, and the high-pressure oil is transported from its lower inner cavity to the lower inner cavity of the corresponding second hydraulic rod 52. The piston output end of the second hydraulic rod 52 moves upward, driving the left supporting plate 41 to rise, so that the left side of the brush wheel 40 is close to the roller 10, increasing the force acting on the left side of the roller 10, and making the cleaning effect better.
[0087] like Figure 3 As shown, in some embodiments of the present invention, the support shaft 23 is rotatably mounted on the support base 30 and is provided with a torsion spring 25;
[0088] One end of the torsion spring 25 is connected to the shoulder of the support shaft 23, and the other end is connected to the support base plate 30;
[0089] Furthermore, the support base plate 30 is provided with a limit block 28 for limiting the rotation angle of the support shaft 23;
[0090] Specifically, the torsion spring 25 is used to provide torsion for the support shaft 23 to ensure that the vertical roller 21 is close to the edge of the belt and can act on the vertical roller 21 when the belt deviates;
[0091] The limiting block 28 is used to limit the support shaft 23. The limiting structure can be a limiting rod provided on the support shaft 23 to match the limiting block 28. Under the action of the torsion spring 25, the limiting rod contacts the limiting block 28.
[0092] In the initial state, under the action of the torsion spring 25 and the limit block 28, the support shaft 23 is at a certain angle. At this time, the vertical roller 21 is close to the edge of the belt, one end of the connecting component is located at the high point of the arc track 241, and under the pair of adjustment components, the support plate 41 is in a horizontal state, that is, the axis of the brush wheel 40 is consistent with the axis of the roller 10;
[0093] When the belt deviates and the vertical roller 21 drives the rotating arm 22 to rotate, the support shaft 23 rotates to compress the torsion spring 25;
[0094] After the brush wheel 40 is adjusted and the roller 10 is cleaned, under the action of the torsion spring 25, the vertical roller 21 can give the belt a certain lateral force, so that the belt returns to the original conveying center, and can make the adjustment disk 24, the connecting assembly, and the supporting plate 41 all in the initial state to respond to the next belt deviation.
[0095] like Figure 7 As shown, in some embodiments of the present invention, the brush wheel 40 is an inner brush 43 and an outer brush 44 provided on a brush shaft 42;
[0096] The inner brushes 43 are harder than the outer brushes 44 and are relatively more numerous;
[0097] Specifically, in the initial state, the outer brush 44 on the brush wheel 40 can contact the surface of the roller 10 for rough cleaning, that is, light cleaning, which can clean small attachments such as dust to avoid dust accumulation;
[0098] When the belt deviates, the inner brush 43 on the brush wheel 40 contacts the surface of the roller 10 for fine cleaning, i.e., the cleaning intensity is greater, and it can clean direct and large attachments such as material splashing and belt wear;
[0099] This embodiment can be used in different usage environments, avoiding the ineffective cleaning of traditional cleaning rollers and being more targeted.
[0100] In some embodiments of the present invention, one end of the brush wheel 40 is connected to a drive motor or a transmission assembly;
[0101] When it is a transmission assembly, the transmission assembly has a first gear, a second gear, a first moving wheel, and a second moving wheel;
[0102] The first gear is fixed on the shaft where the roller 10 is located and is meshed with the second gear;
[0103] The first moving wheel rotates coaxially with the second gear and is connected to the second moving wheel via a transmission belt wound around the outside of the first moving wheel, and the transmission belt is elastically tensioned;
[0104] The second moving wheel is fixed to the end side of the brush wheel 40;
[0105] Specifically, the driving motor may be a servo motor. Under the action of the driving motor or the transmission assembly, the brush wheel 40 rotates and the rotation direction is opposite to the belt conveying direction, thereby ensuring that the brush wheel 40 cleans the belt.
[0106] Example 4
[0107] When the roller 10 receives the belt and rotates along with the belt, the first gear on the roller 10 transmits power to the second gear and the coaxially arranged first moving wheel, and then transmits power to the second moving wheel and the brush wheel 40 through the transmission belt;
[0108] That is, the roller 10 drives the brush wheel 40 in conjunction with the transmission assembly, thereby avoiding the need for an additional drive motor and being suitable for locations where it is inconvenient to use a power source.
[0109] It is also noted that a tensioning assembly needs to be provided on the transmission belt at this time, which can ensure that the transmission belt is always in a taut state, and avoid the problem of reduced transmission efficiency of the transmission belt caused by adjustment and cleaning of the brush wheel 40 when the belt deviates.
[0110] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
