Description

Technical Field

[0001] The utility model relates to an automatic I-beam feeding device for a steel arch production line which can also take passive feeding into consideration, and belongs to the technical field of I-beam conveying. Background Art

[0002] Steel arch supports are often required in tunnels, subways, hydropower stations, underground caverns and other projects. Currently, automated steel arch production lines have been gradually adopted for production, and the automatic feeding of I-beams is a part of the steel arch production line.

[0003] Currently, the industry's common method for automatically conveying I-beams for steel arches is to use a speed reducer and chain drive to drive the conveyor rollers, thereby conveying the I-beams. However, once the I-beams enter the cold bending machine, their movement is driven by the cold bending machine. This presents a problem, requiring the conveying speed of the I-beam conveyor line to be completely synchronized with the cold bending machine, and the conveyor line to be in operation at all times. Otherwise, the I-beams will drag on the conveyor rollers, easily causing significant wear and tear on the conveyor rollers and equipment failure. Furthermore, since the I-beams on the cold bending machine move at only half the speed of the I-beam conveyor line, any synchronization will reduce the efficiency of the conveying equipment, thereby affecting the production efficiency of the entire steel arch production line. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an automatic feeding device for I-beams in a steel arch frame production line that can take into account passive feeding. The device solves the speed coordination problem of I-beam transportation and cold bending machine, improves the I-beam transportation efficiency, reduces equipment failures, ensures stable equipment operation, and the device has a simple structure, is easy to use, and operates reliably.

[0005] The utility model provides an automatic feeding device for I-beams of a steel arch production line that can take into account passive feeding, comprising a feeding platform, on which are mounted a plurality of rotatable conveying rollers arranged in parallel, and the plurality of conveying rollers are connected by a first transmission chain; the conveying roller comprises a conveying roller shaft, a conveying roller cylinder sleeved on the outer periphery of the conveying roller shaft, and a sprocket sleeved on the outer periphery of the conveying roller shaft and fixedly connected to the conveying roller shaft, the sprocket being located on one side of the conveying roller cylinder, the conveying roller cylinder and the conveying roller shaft being connected by a one-way bearing, and at least one of the sprockets being connected to a driving mechanism via a second transmission chain.

[0006] In one embodiment of the present invention, the first transmission chain is connected to the outer periphery of the sprocket of the conveying roller.

[0007] In one embodiment of the present invention, the sprocket is connected to the conveying roller shaft via a pin.

[0008] In one embodiment of the present invention, it further comprises a bearing seat fixedly mounted on the feeding platform, and both ends of the conveying roller are rotatably disposed in the two bearing seats.

[0012] In one embodiment of the present invention, a fixing seat is installed inside the feeding platform, and the driving mechanism is fixedly installed on the fixing seat.

[0013] In one embodiment of the present invention, the driving mechanism includes a driving motor and a reducer connected thereto, and the reducer is connected to the second transmission chain.

[0016] The utility model provides an automatic feeding device for I-beams in a steel arch production line that can take into account both passive feeding and active feeding of I-beams. During active feeding, the driving mechanism works, driving the conveying roller body and the conveying roller shaft to rotate synchronously to convey the I-beam, and no relative rotation occurs between the conveying roller body and the conveying roller shaft; during passive feeding, the driving mechanism does not work, and the conveying roller shaft does not rotate. Since the conveying roller body and the conveying roller shaft of the conveying roller are connected by a one-way bearing, the conveying roller body can rotate unidirectionally around the conveying roller shaft, that is, the conveying roller body can passively rotate in the forward feeding direction. Specifically, the movement of the I-beam is achieved by the drive of the cold bending machine, which drives the I-beam to move and the conveying roller body to roll in the forward feeding direction, without causing any impact on the equipment. This achieves complete synchronization of the conveying speed of the I-beam conveyor line with the cold bending machine, and ensures that the conveyor line is always in working condition, avoiding the problem of large wear of the conveying roller and equipment failure caused by the I-beam dragging the conveying roller. The I-beam automatic feeding device has a simple structure, convenient and flexible operation, and reliable action. It solves the speed coordination problem between the I-beam conveying and the cold bending machine, improves the I-beam conveying efficiency, ensures the production efficiency of the entire steel arch production line, reduces equipment failures, and ensures stable equipment operation.

[0026] like Figure 1-5 As shown, an embodiment of the present application provides an automatic feeding device for I-beams in a steel arch production line that can take into account passive feeding. The device solves the speed coordination problem of I-beam transportation and cold bending machine, improves the I-beam transportation efficiency, reduces equipment failures, ensures stable equipment operation, and the device has a simple structure, is easy to use, and operates reliably.

[0027] In some embodiments, the automatic feeding device for I-beams includes a feeding platform 1, on which are mounted several rotatable conveying rollers 3 arranged in parallel, and the several conveying rollers 3 are connected by a first transmission chain 5; the conveying roller 3 includes a conveying roller shaft 33, a conveying roller cylinder 32 sleeved on the outer periphery of the conveying roller shaft 33, and a sprocket 35 sleeved on the outer periphery of the conveying roller shaft 33 and fixedly connected to the conveying roller shaft 33, the sprocket 35 is located on one side of the conveying roller cylinder 32, the conveying roller cylinder 32 and the conveying roller shaft 33 are connected by a one-way bearing 34, and at least one of the sprockets 35 is connected to the driving mechanism 4 through a second transmission chain 8.

[0028] Specifically, at least one of the plurality of conveyor rollers 3 is connected to the drive mechanism 4 via its sprocket 35 and the second transmission chain 8. In this embodiment, there is only one drive mechanism 4 and one second transmission chain 8. The drive mechanism 4 is connected to the sprocket 35 of the frontmost conveyor roller 3 via the second transmission chain 8. The drive mechanism 4 is capable of driving the plurality of interconnected conveyor rollers 3 to rotate via the conveyor roller 3 and the second transmission chain 8.

[0029] Furthermore, the first transmission chain 5 is connected to the outer periphery of the sprocket 35 of the conveying roller 3 .

[0030] In this embodiment, the conveyor roller shafts 33 and sprockets 35 of several interconnected conveyor rollers 3 rotate synchronously driven by the first transmission chain 5. Specifically, the drive mechanism 4 drives the sprocket 35 and conveyor roller shaft 33 of one of the conveyor rollers 3 to rotate via the second transmission chain 8. Because the conveyor rollers 3 are connected by the first transmission chain 5, the rotation of one conveyor roller 3 drives the synchronous rotation of all the interconnected conveyor rollers 3.

[0031] Furthermore, the sprocket 35 is connected to the conveying roller shaft 33 via a pin, thereby achieving a fixed connection between the sprocket 35 and the conveying roller shaft 33 and synchronous rotation.

[0032] Furthermore, it also includes a bearing seat 31 fixedly installed on the feeding platform 1, and both ends of the conveying roller 33 are rotatably arranged in the two bearing seats 31.

[0033] The embodiment of the present application provides an automatic feeding device for I-beams in a steel arch production line that can take into account passive feeding. After assembly, the sprocket 35 and the conveyor roller 33 move together and rotate synchronously. When the conveyor roller 33 is not working, since the conveyor roller body 32 and the conveyor roller shaft 33 are connected by a one-way bearing 34, and there is no contact between the sprocket 35 and the conveyor roller body 32, when the conveyor roller shaft 33 is not rotating, the conveyor roller body 32 can rotate unidirectionally around the conveyor roller shaft 33, that is, the conveyor roller body 32 can passively rotate toward the forward feeding direction.

[0034] Furthermore, the conveying roller body 32 is in contact with the I-beam 6 , and the I-beam 6 is mounted on the conveying roller body 32 .

[0035] In some embodiments, side stop wheels 2 are also included, and several of the side stop wheels 2 are rotatably mounted on the upper part of the feeding platform 1. Several of the side stop wheels 2 are arranged in a strip shape on one side of the first transmission chain 5, and the side stop wheels 2 are located above the conveying roller 3 and the first transmission chain 5.

[0036] In this embodiment, the side stop wheels 2 are provided to guide the movement of the I-beam 6, which can effectively prevent the I-beam 6 from rubbing and colliding with the equipment, so that the I-beam 6 can be transported smoothly.

[0037] In some embodiments, a fixing seat 7 is installed inside the feeding platform 1 , and the driving mechanism 4 is fixedly installed on the fixing seat 7 .

[0038] Optionally, the driving mechanism 4 includes a driving motor and a reducer connected thereto, and the reducer is connected to the second transmission chain 8 .

[0039] During use, after the I-beam enters the automatic I-beam feeding device provided by the present invention, the drive mechanism 4 operates, driving the sprocket 35 and conveyor roller shaft 33 of one of the conveyor rollers 3 to rotate via the second transmission chain 8. Since several conveyor rollers 3 are connected by the first transmission chain 5, the rotation of one conveyor roller 3 drives all the interconnected conveyor rollers 3 to rotate synchronously, thereby conveying the I-beam 6 on the conveyor rollers 3 forward. The side blocking wheels 2 on both sides effectively prevent the I-beam 6 from rubbing and colliding with the equipment; after the conveyed I-beam 6 docks with the tail end of the preceding I-beam 6, the drive mechanism 4 stops operating.

[0040] After the front and rear I-beams 6 are butt-welded, the cold bending machine starts working. The I-beam 6 continues to move while being bent into an arch under the action of the cold bending machine. At this time, since the conveying roller body 32 of the conveying roller 3 is connected to the conveying roller shaft 33 through a one-way bearing 34, the automatic feeding device for the I-beam does not need to open the driving mechanism 4. The cold bending machine can drive the I-beam 6 to move and the conveying roller body 32 to roll in the feeding direction, which will not cause any impact on the equipment.

[0041] In summary, the present application provides an automatic feeding device for I-beams in a steel arch production line that can take into account both passive feeding and active feeding. It can realize both active feeding of I-beams 6 and passive feeding of I-beams 6. During active feeding, the drive mechanism 4 works, driving the conveying roller body 32 and the conveying roller shaft 33 to rotate synchronously to convey the I-beam 6, and no relative rotation occurs between the conveying roller body 32 and the conveying roller shaft 33; during passive feeding, the drive mechanism 4 does not work, and the conveying roller shaft 33 does not rotate. Since the conveying roller body 32 and the conveying roller shaft 33 of the conveying roller 3 are connected by a one-way bearing 34, the conveying roller body 32 can rotate unidirectionally around the conveying roller shaft 33, that is, the conveying roller body 32 can passively rotate toward the forward direction of feeding. Specifically, the movement of the I-beam 6 is achieved by the drive of the cold bending machine, which drives the I-beam 6 to move and the conveying roller body 32 to roll in the feeding direction, without causing any impact on the equipment. The conveying speed of the I-beam conveyor line is completely synchronized with the cold bending machine, and the conveyor line is always in working condition, avoiding the problem of large wear and equipment failure of the conveying roller 3 caused by the I-beam 6 dragging the conveying roller 3. The automatic feeding device for I-beams has a simple structure, convenient and flexible operation, and reliable action. It solves the speed coordination problem of I-beam conveying and cold bending machine, improves the I-beam conveying efficiency, ensures the production efficiency of the entire steel arch production line, reduces equipment failures, and ensures stable equipment operation.
