Description

Technical Field

[0001] The invention relates to the technical field of belt supports, and in particular to a towing device and a towing system. Background Art

[0002] In the process of conveying materials, the belt conveyor has a strong elasticity, and the tension and relaxation degree under load and without load are different. Especially when conveying materials, the belt relaxation directly affects and reduces the friction between the belt and the power drive wheel. To maintain its tension, the belt must be tightened. With the continuous increase in the conveying distance of a single machine, the tensioning distance of the belt conveyor also increases. Car tensioning is a tensioning form often used in long-distance belt conveyors. With the increase in the tensioning distance, the distance between the tensioning roller and the front redirecting roller becomes larger and larger. If the belt in this distance is not supported, it will cause the belt to sag. In severe cases, it will cause the belt to drag on the ground, scratch the belt, and cause the roller to slip. In addition, when the belt is set in multiple layers, the mutual interference between the belts of each layer will also seriously affect the normal operation of the belt. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that multiple layers of belts are prone to interfere with each other when the suspended distance is long, thereby providing a towing device that can ensure that the multiple layers of belts do not interfere with each other.

[0004] Another technical problem to be solved by the present invention is to overcome the defect in the prior art that the multiple layers of belts are easily interfered with each other due to the multiple layers of belt winding of the belts in multiple layers when the moving distance is shortened, thereby providing a towing system that can shorten the moving distance to a great extent and ensure that the multiple layers of belts do not interfere with each other.

[0025] The technical solution of the present invention has the following advantages:

[0026] 1. The towing device provided by the present invention can lift a belt arranged in multiple layers, wherein the movable towing part can be movably installed on the towing device, and as the position of the belt is adjusted, or as the relative position of the towing device and the belt changes, the position of the movable towing part on the towing device is changed, so that the movable towing part maintains the lifting state of the belt, thereby ensuring the normal operation of the belt and ensuring that the multiple layers of belts do not interfere with each other.

[0027] 2. The towing device provided by the present invention is provided with rollers at the upper part, the middle part and the lower part respectively, and the upper and lower rollers are arranged in a fixed form, which is convenient for lifting the belt whose positions with the rollers remain relatively unchanged, especially for lifting the belt that maintains horizontal movement, and is also applicable when the towing device and the belt maintain relative horizontal movement; and a second roller is fixedly connected at a fixed position so that the second roller can be adjusted in height in the vertical direction relative to the towing device, so that when the positions of the belt and the roller change relatively, the second roller can be adjusted in height on the towing device so that the belt can be kept lifted by the second roller again by adjusting the height of the second roller on the towing device, thereby increasing the applicability and flexibility of the towing device.

[0028] 3. The towing device provided by the present invention can ensure that the second towing traveling wheel always moves along the direction of the guide rail guide through the cooperation between the second towing traveling wheel and the guide rail guide, thereby ensuring that the running direction of the towing device always follows the guide rail to prevent deviation.

[0029] 4. The towing device provided by the present invention can clamp the towing device on the guide rail to prevent the towing device from accidentally slipping off the guide rail by respectively arranging the vertical positioning guide wheel and the first towing traveling wheel and / or the second towing traveling wheel on opposite sides of the guide rail in the horizontal direction; at the same time, the rotation axis of the horizontal positioning guide wheel and the rotation axis of the vertical positioning guide wheel are arranged at an angle, so that the horizontal positioning guide wheel and the vertical positioning guide wheel can be clamped on the guide rail in two directions, which can prevent the towing device from moving in the horizontal direction relative to the guide rail and prevent the towing device from moving in the vertical direction relative to the guide rail, thereby ensuring the positioning accuracy of the towing device.

[0030] 5. The towing system provided by the present invention realizes the number of winding sections of the belt on the tensioning mobile platform by cooperating the combined redirecting roller seat with the tensioning mobile platform, thereby reducing the moving distance of the tensioning mobile platform and shortening the tensioning stroke when the belt is stretched to the same length.

[0031] 6. In the towing system provided by the present invention, the tensioning mobile platform is connected to the towing device through a towing guide chain of a preset length, so that after the towing guide chain is straightened, the towing device moves along with the movement of the tensioning mobile platform, thereby achieving automatic following and ensuring the towing distance.

[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] Embodiment 1

[0058] Combination Figure 1-Figure 3 As shown, a towing device 24 includes:

[0059] At least one fixed entraining portion, which is fixedly mounted on the entraining device 24 and is suitable for lifting the belt 100 that maintains horizontal movement;

[0060] At least one movable traction part is movably mounted on the traction device and is suitable for lifting the belt 100 in a tilting motion state.

[0061] The towing device provided by the present invention can lift a belt arranged in multiple layers, wherein the movable towing part can be movably installed on the towing device, and as the position of the belt is adjusted, or as the relative position of the towing device and the belt changes, the position of the movable towing part on the towing device is changed, and the lifting state of the belt by the movable towing part is maintained, thereby ensuring the normal operation of the belt and ensuring that the multiple layers of belts do not interfere with each other.

[0062] Specifically, the fixed towing part includes: a first roller 241 and a third roller 243; the first roller 241 and the third roller 243 are fixedly installed on the upper part and the lower part of the towing device respectively;

[0063] The movable towing part includes: a second roller 242, which is located in the middle of the first roller 241 and the third roller 243 in the vertical direction; the second roller 242 is fixedly connected to at least one second roller fixing position 2422 on the towing device.

[0064] When the towing device lifts the belt, due to the different winding forms of the belt, the multi-layer belt forms formed are often different. The towing device provided by the present invention is respectively provided with rollers at the upper, middle and lower parts, and the upper and lower rollers are arranged in a fixed form, which is convenient for lifting the belt while the positions of the belt and the rollers remain relatively unchanged, especially for lifting the belt 100 that maintains horizontal movement, and is also applicable when the towing device and the belt maintain relative horizontal movement.

[0065] In addition, a movable second roller 242 is provided in the middle of the towing device, and is fixedly connected by a second roller fixing position 2422, so that the second roller 242 can be adjusted in height in the vertical direction relative to the towing device. Therefore, when the positions of the belt and the roller change relative to each other, the height of the second roller 242 on the towing device is adjusted, so that the second roller 242 can be kept in a lifting state for the belt again, thereby increasing the applicability and flexibility of the towing device.

[0066] As a specific implementation form, the first roller 241 is fixed to the upper part of the towing device through a first roller positioning member 2411; the second roller 242 is fixedly connected to the second roller fixing position 2422 on the towing device through a second roller positioning member 2421.

[0067] Specifically, at least one of the second roller fixing positions 2422 is provided along the vertical direction of the towing device. Therefore, when the relative positions of the belt and the roller change, by adjusting the height of the second roller 242 on the towing device, the second roller 242 can be made to hold the belt again, thereby increasing the applicability and flexibility of the towing device. As a modified implementation form of a single movable towing portion, the movable towing portion can include multiple rollers, and the multiple rollers are respectively fixedly connected to at least one of the second roller fixing positions 2422 on the towing device, so that the towing device can have multiple movable towing portions, increasing the number of layers of the towing device holding the belt, and having strong applicability.

[0068] Specifically, the towing device further includes: a first towing traveling wheel 244 , which is suitable for sliding along the upper surface of the guide rail 201 ; and a second towing traveling wheel 245 , which is suitable for sliding along the guide rail guide 202 provided on the upper surface of the guide rail 201 .

[0069] Specifically, a protrusion or a groove is provided on the guide rail guide 202, and a groove or a protrusion is provided on the second towing traveling wheel 245 matched with the guide rail guide 202, and the groove matches the shape of the protrusion. Through the cooperation between the second towing traveling wheel 245 and the guide rail guide 202, it can be ensured that the second towing traveling wheel 245 always moves along the direction of the guide rail guide 202, thereby ensuring that the running direction of the towing device is always along the guide rail 201 to prevent deviation.

[0070] Preferably, the first towing traveling wheel 244 and the second towing traveling wheel 245 are respectively arranged on both sides of the towing device along the length direction, that is, the guide rail guide 202 is arranged on the upper surface of one guide rail 201, and the guide rail guide 202 is not arranged on the other guide rail 201, so that the traveling wheel on one side ensures the traveling direction and the traveling wheel on the other side ensures the fault tolerance rate, thereby avoiding the towing device from running smoothly due to the unevenness of the guide rails 201 when the guide rail guides 202 are arranged on both sides of the guide rails.

[0071] As a specific implementation form, combined with Figure 3As shown, the guide rail 201 can be a channel steel, and the first traction running wheel 244 is slidably matched with the outer surface of the flange plate of the channel steel. The guide rail guide 202 on the upper surface of the guide rail 201 is an angle steel fixedly mounted on the outer surface of the flange plate of the channel steel, and the structure of the second traction running wheel 245 matches the angle steel, so that the second traction running wheel 245 slides on the angle steel. The guide rail 201 can also be an I-beam, and its matching form is similar to that of the channel steel, which will not be repeated here.

[0072] Specifically, the towing device further includes: a vertical positioning guide wheel 246, the vertical positioning guide wheel 246 is slidably matched with the guide rail 201, the rotation axis of the vertical positioning guide wheel 246 is parallel to the rotation axis of the first towing traveling wheel 244 and / or the second towing traveling wheel 245, and the vertical positioning guide wheel 246 and the first towing traveling wheel 244 and / or the second towing traveling wheel 245 are respectively arranged on opposite sides of the guide rail 201 along the horizontal direction;

[0073] The horizontal positioning guide wheel 247 is slidably matched with the guide rail 201 , and the rotation axis of the horizontal positioning guide wheel 247 is set at an angle with the rotation axis of the vertical positioning guide wheel 246 .

[0074] By respectively arranging the vertical positioning guide wheel 246 and the first towing traveling wheel 244 and / or the second towing traveling wheel 245 on opposite sides of the guide rail 201 in the horizontal direction, the towing device can be clamped on the guide rail 201 to prevent the towing device from accidentally slipping off the guide rail 201; at the same time, the rotation axis of the horizontal positioning guide wheel 247 and the rotation axis of the vertical positioning guide wheel 246 are arranged at an angle, so that the horizontal positioning guide wheel 247 and the vertical positioning guide wheel 246 can be clamped on the guide rail 201 in two directions, which can prevent the towing device from moving in the horizontal direction relative to the guide rail 201 and prevent the towing device from moving in the vertical direction relative to the guide rail 201, thereby ensuring the positioning accuracy of the towing device.

[0075] Preferably, the guide rail 201 is a channel steel, the vertical positioning guide wheel 246 is in sliding cooperation with the inner surface of the flange plate of the channel steel, and the horizontal positioning guide wheel 247 is in sliding cooperation with the inner surface of the web plate of the channel steel.

[0076] Embodiment 2

[0077] Combination Figure 4-Figure 6 As shown, a towing system comprises:

[0078] The belt 100 is a continuous belt connected end to end;

[0079] A tensioning mobile platform 21 is slidably disposed on the tensioning frame 20, and includes at least one tensioning mobile platform roller, wherein the tensioning mobile platform roller is suitable for winding the belt 100;

[0080] A combined redirecting roller seat 13, which includes at least two combined redirecting rollers; the combined redirecting roller seat 13 is suitable for redirecting the two ends of the belt 100 transported from the belt tower 11, and is suitable for cooperating with the tensioning mobile platform 21 to increase the number of winding sections of the belt 100 on at least one of the tensioning mobile platform rollers of the tensioning mobile platform 21;

[0081] After the two ends of the belt 100 are redirected by the first combined redirecting roller 131 and the second combined redirecting roller 132, the first end of the belt 100 is wound around the first tensioning mobile platform roller 211, and the second end of the belt 100 is wound around the second tensioning mobile platform roller 212 and / or the third tensioning mobile platform roller 213, and they are connected after being wound around both sides of the third combined redirecting roller 133 respectively; the towing system also includes:

[0082] At least one traction device 24 as described above, which is suitable for lifting the multiple layers of the belt 100 between the combined redirecting roller seat 13 and the tensioning moving platform 21.

[0083] Preferably, the towing device 24 is disposed on the tensioning frame 20 , and performs follow-up lifting of the multiple layers of the belt 100 between the combined redirecting roller seat 13 and the tensioning mobile platform 21 .

[0084] By cooperating the combined redirecting roller seat 13 with the tensioning mobile platform 21, the number of winding sections of the belt 100 on the tensioning mobile platform 21 is realized, and then when the belt 100 is stretched to the same length, the moving distance of the tensioning mobile platform 21 is reduced, shortening the tensioning stroke.

[0085] As a specific implementation form, the tensioning mobile platform 21 is further provided with a tensioning mobile platform pulley 214, and the tensioning mobile platform pulley 214 is suitable for being pulled by a steel wire rope, thereby driving the tensioning mobile platform 21 to slide along the tensioning frame 20;

[0086] By winding the belt 100 on the tensioning mobile platform drum, the tensioning mobile platform drum pulls a section of the belt 100 to move, wherein a≥2, the tensioning mobile platform drum can form a movable pulley or a movable pulley group, and then when the tensioning mobile platform pulley 214 moves a distance of X, that is, when the tensioning mobile platform drum moves a distance of X, the belt 100 is driven to move a distance of X·a, wherein X≥0m.

[0087] As the best implementation form of the present invention, we will take a specific implementation scheme as an example to provide a detailed description. It is set that the tensioning mobile platform roller pulls the 4 sections of the belt 100 to move. When the tensioning mobile platform pulley moves synchronously for a distance of 6 meters, the tensioning mobile platform roller moves for a distance of 6 meters, which drives the belt 100 to move for a distance of 6×4=24 meters. Since the belt is a continuous belt connected end to end, when the total length of the belt moves 24 meters, the actual moving length of the belt is 24÷2=12 meters. Therefore, through the towing system provided by the present invention, when the tensioning mobile platform moves a distance of 6 meters, the belt 100 actually moves a distance of 12 meters, achieving a pulling effect of twice the distance, thereby reducing the length of the tensioning frame by half, greatly reducing the cost.

[0088] The scheme of the present invention is particularly suitable for belt conveyors with ultra-long distances and large transport volumes. The tensioning stroke of such belt conveyors is very long. If a traditional tensioning device is used, the tensioning frame will be too long, which will undoubtedly increase the length of the tensioning frame and increase the cost. More seriously, due to differences in the conditions of the construction site, it may even be impossible to meet the construction requirements due to space limitations. Therefore, the belt conveyor adaptive tensioning system provided by this scheme can shorten the length of the tensioning frame and meet the construction requirements of small construction sites, saving production costs, achieving considerable economic benefits, and having strong adaptability.

[0089] As a specific implementation form, the combined redirecting roller seat 13 includes: a first combined redirecting roller 131 and a second combined redirecting roller 132, wherein the first combined redirecting roller 131 is suitable for redirecting the first end of the belt 100 conveyed from the belt tower 11, and the second combined redirecting roller 132 is suitable for redirecting the second end of the belt 100 conveyed from the belt tower 11. The combined redirecting roller seat 13 also includes: a third combined redirecting roller 133, wherein the third combined redirecting roller 133 is suitable for cooperating with the tensioning mobile platform 21 to wind the belt 100 wound back by the tensioning mobile platform roller, so as to increase the number of winding sections of the belt 100 on the tensioning mobile platform 21.

[0090] Preferably, the combined redirecting roller seat 13 is arranged on the ground, which is suitable for sharing the force of the belt tower. Due to the constant work characteristic of the pulley block, W=F·S, wherein W is work, F is force, and S is distance. When the distance S becomes shorter, the work W remains unchanged and the force F is bound to increase. Then, the combined redirecting roller seat 13 can share the additional force, so that the belt tower only bears the tension of the belt 100, thereby reducing the operation risk of the belt tower.

[0091] Specifically, after the two ends of the belt 100 are redirected by the first combined redirecting roller 131 and the second combined redirecting roller 132 respectively, the first end of the belt 100 is wrapped around the first tensioning mobile platform roller 211, and the second end of the belt 100 is wrapped around the second tensioning mobile platform roller 212 and / or the third tensioning mobile platform roller 213, and they are merged and connected after respectively wrapping around both sides of the third combined redirecting roller 133.

[0092] By arranging a plurality of combined redirecting rollers on the combined redirecting roller seat 13, the belt 100 is wound between the combined redirecting roller seat 13 and the tensioning mobile platform 21, and at the same time plays a role in sharing the extra force of the belt tower.

[0093] Specifically, a traveling wheel is provided at the bottom of the tensioning mobile platform 21, and the traveling wheel is suitable for driving the tensioning mobile platform 21 to translate along the tensioning frame 20. A guide wheel assembly is also provided at the bottom of the tensioning mobile platform 21, and the guide wheel assembly is suitable for sliding along the tensioning frame 20 for guiding and positioning. The guide wheel assembly and the traveling wheel are respectively provided at the upper and lower sides of the guide rail 201, so that the tensioning mobile platform 21 is clamped and installed on the guide rail 201, so as to prevent the tensioning mobile platform 21 from tilting or deflecting due to uneven force, thereby ensuring the smooth operation of the tensioning mobile platform 21. The guide wheel assembly is also suitable for guiding the tensioning mobile platform 21 in the horizontal direction to prevent the tensioning mobile platform 21 from slipping off the guide rail 201.

[0094] Specifically, the tensioning mobile platform 21 is connected to the towing device 24 via a towing guide chain 25 of a preset length, so that the towing device 24 moves following the movement of the tensioning mobile platform 21 after the towing guide chain 25 is straightened.

[0095] As a specific implementation form, a first fixed end 251 of a towing guide chain is fixedly provided on the combined redirecting roller seat 13, and a second fixed end 252 of a towing guide chain is fixedly provided on the tensioning mobile platform 21. The two ends of the towing guide chain 25 are fixed by the first fixed end 251 of the towing guide chain and the second fixed end 252 of the towing guide chain, so that the towing guide chain 25 has a fixed length between the combined redirecting roller seat 13 and the tensioning mobile platform 21. As the tensioning mobile platform 21 moves relative to the combined redirecting roller seat 13, the towing guide chain 25 is gradually tightened or loosened.

[0096] Furthermore, by arranging a plurality of the towing devices 24 on the tensioning frame 20, and the towing guide chain 25 is fixedly connected to one of the towing devices 24 at intervals. In the following, taking the arrangement of two towing devices 24 on the tensioning frame 20 as an example, after the tensioning mobile platform 21 moves, the towing guide chain 25 is gradually tightened and then the first towing device 24 is driven to move. When the first towing device 24 moves a certain distance and gradually tightens the towing guide chain 25 between the first towing device 24 and the second towing device 24, the second towing device 24 is driven to move, thereby realizing automatic following and ensuring the towing distance.

[0097] Specifically, the towing system further comprises a guide rope 26, and the guide rope 26 is suitable for suspending the towing guide chain 25 through at least two lifting rings 253;

[0098] Combination Figure 8 As shown, the towing device 24 is also provided with a through plate 248, and the through plate 248 is suitable for clamping the towing guide chain 25 and lifting the guide rope 26 at the same time.

[0099] The guide rope 26 is always in a taut and straightened state and is arranged above the towing guide chain 25. By arranging a lifting ring 253 on the guide rope 26 and suspending the towing guide chain 25, it plays the role of storing the guide chain, which can prevent the towing guide chain from loosening, reduce the risk of the towing guide chain 25 interfering with the normal operation of the equipment, and reduce the accident rate.

[0100] As a specific implementation form, a first fixed end 261 of the guide rope is fixedly provided on the combined redirecting roller seat 13, and a second fixed end 262 of the guide rope is fixedly provided on the side of the tensioning frame 20 away from the combined redirecting roller seat 13, and the two ends of the guide rope 26 are fixed by the first fixed end 261 of the guide rope and the second fixed end 262 of the guide rope, and the relative distance between the side of the tensioning frame 20 away from the combined redirecting roller seat 13 and the combined redirecting roller seat 13 remains unchanged, thereby ensuring that the guide rope 26 is always in a taut and straightened state.

[0101] The through plate 248 is fixedly arranged on one side of the towing device 24, and is provided with a guide groove and a hanging groove, wherein the guide groove is suitable for lifting the guide rope 26, and the hanging groove is suitable for clamping the towing guide chain 25. Since the guide rope 26 is relatively long, by arranging the through plate 248 on the towing device 24, the guide rope 26 can be supported to a certain extent to avoid loosening.

[0102] Specifically, the towing system further includes a frame roller 203 , and the frame roller 203 is arranged on at least one leg 204 of the tensioning frame 20 .

[0103] By arranging frame rollers 203 on the legs 204 of the tensioning frame 20, the belt running below the upper surface of the guide rail 201 can be lifted, the leg structure is reasonably utilized, and the lower rollers are avoided from being arranged on the towing device 24, thereby reducing the force strength of the towing device 24 and ensuring smooth operation.

[0104] Combination Figure 7 As shown, the following takes four-layer belts as an example to further introduce the working mode of the towing device 24. After the combined redirecting roller seat 13 and the tensioning mobile platform 21 are wound together, a first layer of belt 101 located at the top and running in the horizontal direction, a second layer of belt 102 located in the middle and running in the inclined direction, a third layer of belt 103 located in the middle and running in the horizontal direction, and a fourth layer of belt 104 located at the bottom and running in the horizontal direction are formed; wherein, the first layer of belt 101 is lifted by the first roller 241, the second layer of belt 102 is lifted by the second roller 242, the third layer of belt 103 is lifted by the third roller 243, and the fourth layer of belt 104 is lifted by the frame roller 203; thereby ensuring that each layer of belt has a corresponding lifting unit, and ensuring the smooth operation of each layer of belt.

[0105] Specifically, a tensioning and redirecting roller seat 12 is provided on the belt tower 11, and the tensioning and redirecting roller seat 12 includes: a first tensioning and redirecting roller 121, and the first tensioning and redirecting roller 121 is suitable for redirecting the first end of the belt 100 and guiding it to the first combined redirecting roller 131;

[0106] The second tensioning and redirecting roller 122 is adapted to redirect and guide the second end of the belt 100 to the second combined redirecting roller 132 .

[0107] Preferably, at least one entrainment device 111 is also provided on the belt tower 11, and the entrainment device 111 is suitable for guiding the belt 100. Since the belt tower 11 is relatively high, the belt 100 is prone to vibrate and deviate during operation. By arranging a plurality of the entrainment devices 111 on the belt tower 11, it is possible to ensure that the belt 100 runs smoothly and reduce the deviation rate.

[0108] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
