Description

Technical Field

[0001] This utility model relates to the field of steel pipe conveying technology, and specifically to a horizontal steel pipe conveying device. Background Technology

[0002] In the production of steel pipes, the steel plate on the outer periphery of the roll is released and the stress is relieved by the unwinding device. Then the steel plate is conveyed to the forming roll position and wound into a tube shape. After welding, the steel plate is welded into a tube shape. Finally, it is cut to a fixed length to realize the output. The steel pipe is sent to the packaging area by the horizontal conveying device.

[0003] The existing horizontal steel pipe conveying devices still have the following shortcomings during use: 1) When the steel pipe is transported to the end, the impact force generated by inertia lacks effective buffering, which often causes scratches on the surface of the steel pipe and deformation of the end. This is especially true for steel pipes with high precision requirements, which directly affects product quality. 2) The transfer of steel pipes between different supports often relies on manual assistance or simple guiding structures, which is not only labor-intensive and inefficient, but also prone to safety hazards due to improper manual operation.

[0004] 3) Although mechanical degreasing can remove some of the oil stains attached to the inner and outer walls of the steel pipe, it cannot guarantee complete removal, and some oil stains will still remain.

[0005] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

[0026] [First Embodiment] like Figure 1-5 The diagram shows a horizontal steel pipe conveying device according to the first embodiment of this utility model. It includes a first support 1 and a second support 10 arranged parallel to each other. The first support 1 and the second support 10 are the main support structures of the device. Several transmission rollers 2 are mounted inside the first support 1 via bearing seats. The transmission rollers 2 are arranged sequentially along the steel pipe conveying direction, and the installation height of the bearing seats gradually decreases from the input end to the output end of the first support 1, forming an inclined conveying surface. This allows the steel pipe to slide smoothly along the transmission rollers 2 towards the output end under the rotational force of the transmission rollers 2 and its own gravity. The outer side of the first support 1... A drive assembly connected to the transmission rollers 2 is provided. In this embodiment, the drive assembly includes a first motor 5 mounted on the outside of the first bracket 1. The first motor 5 is fixed to the outside of the first bracket 1 by bolts. The output shaft of the first motor 5 is connected to the rotating shaft of one of the transmission rollers 2. Synchronous pulleys 3 are connected to the rotating shafts of one transmission roller 2 and the adjacent rotating shaft of another transmission roller 2. Synchronous belts 4 are connected to the outer periphery of the synchronous pulleys 3 on both sides. The first motor 5 outputs power to drive the transmission roller 2 connected to it to rotate, which drives the synchronous pulley 3 on it to rotate synchronously. Then, through the synchronous belt 4, it drives the other synchronous pulley 3 and the transmission roller 2 fixed to it to rotate synchronously, thereby realizing the synchronous transmission of multiple transmission rollers 2. According to the actual transmission requirements, only one set of synchronous pulleys 3 and synchronous belts 4 can be provided and located between one transmission roller 2 and another adjacent transmission roller 2, or multiple sets can be provided and located between two adjacent transmission rollers 2.

[0027] The improvement of this embodiment compared with the prior art is that: a buffer component 6 is provided on one side of the first support 1 and a transfer component is provided on one side of the first support 1 and the buffer component 6. The transfer component can transfer the steel pipe from the first support 1 to the second support 10. A guide slope 9 is connected between the second support 10 and the first support 1. An auxiliary component 12 and a guide ramp 13 are provided on the second support 10 to transfer the steel pipe from the second support 10 to the packaging area.

[0028] The buffer assembly 6 in this embodiment includes a turntable 62. A circular through hole is provided on one side of the first bracket 1. The turntable 62 is rotatably disposed inside the circular through hole. An annular groove can be machined on the outer periphery of the circular through hole. The turntable 62 is adapted to be installed in the annular groove and can rotate freely. A bearing shaft 61 slides through the inside of the turntable 62. A buffer plate 69 is rotatably connected to the end of the bearing shaft 61 away from the turntable 62. A plurality of sliding grooves 67 are provided on the buffer plate 69. The clamping plate 68 is slidably connected to the buffer plate 69 by sliding cooperation between the inner wall slider and the sliding grooves 67. A plurality of arc-shaped guide grooves 63 are provided inside the turntable 62. A traction rod 64 is movably disposed inside the arc-shaped guide grooves 63. The end of the traction rod 64 away from the arc-shaped guide grooves 63 is fixedly connected to the clamping plate 68.

[0029] To achieve the limiting effect after the angle of the turntable 62 is adjusted, a limiting component is provided on the turntable 62 to limit the rotation angle of the turntable 62. The limiting component includes a limiting pin 65 and a limiting hole. Limiting holes are opened at corresponding positions inside the turntable 62 and the first bracket 1. The limiting pin 65 passes through the turntable 62 and is inserted into the limiting hole at the corresponding position on the first bracket 1 to fix the angle of the turntable 62.

[0030] To secure the buffer pad, a buffer pad is provided on the side of the buffer plate 69 facing the steel pipe. Both the buffer plate 69 and the buffer pad are located inside the clamping plate 68. At the same time, the buffer plate 69 has an installation hole 610 inside for bolt insertion. After the bolt passes through the buffer pad, it is inserted into the installation hole 610 to fix the buffer pad and the buffer plate 69.

[0031] In addition, as a preferred embodiment, in order to achieve elastic reset of the buffer, an elastic reset member 66 is sleeved on the outer periphery of the bearing shaft 61, and the two ends of the elastic reset member 66 are fixedly connected to the bearing shaft 61 and the turntable 62 respectively.

[0032] In this embodiment, one end of the guide slope 9 is fixed to the bottom of the output end of the first bracket 1 by bolts, and the other end is fixed to the top of the input end of the second bracket 10. The surface of the guide slope 9 is provided with a smooth metal plate.

[0033] The transfer assembly includes a second motor 7 and a transfer block 8. The second motor 7 is fixedly mounted on the outside of the first bracket 1 via a mounting base. The transfer block 8 is rotatably connected inside the first bracket 1. The output shaft of the second motor 7 is fixedly connected to the transfer block 8. The transfer block 8 is spoon-shaped, with the spoon head facing the output end of the transmission roller 2 and the spoon handle facing the guide slope 9. The second motor 7 outputs power to drive the transfer block 8 to rotate, thereby transferring the steel pipe from the position of the first bracket 1 to the position of the second bracket 10.

[0034] A V-shaped support block 11 is fixedly installed on the top of the second bracket 10, and the support block 11 is located below the output end of the guide slope 9. In this embodiment, the auxiliary component 12 includes a third motor 121 fixedly mounted on the outside of the second bracket 10 via a mounting bracket. Two rotating wheels 122 are rotatably connected inside the second bracket 10 via bearings. The output shaft of the third motor 121 is fixedly connected to one of the rotating wheels 122. Synchronous pulleys are installed at one end of both rotating shafts and connected by synchronous belt drive. An eccentric shaft 123 is fixedly connected to each of the two rotating wheels 122. A connecting rod 124 is installed at one end of the eccentric shaft 123. A support plate 125 is rotatably connected between the two connecting rods 124. Friction protrusions are set on the surface of the support plate 125 through a vulcanization process. A guide slope 13 is fixedly installed on the top of the output end of the second bracket 10. The other end of the guide slope 13 faces the packaging area. The surface of the guide slope 13 is set as a smooth and inclined metal surface.

[0035] The specific working process of this embodiment includes: When the steel pipe is being transported, it is first placed on the transmission roller 2 of the first support 1. The first motor 5 is started, and the output shaft of the first motor 5 drives the corresponding transmission roller 2 to rotate. The transmission roller 2 drives the other transmission rollers 2 to rotate synchronously through the synchronous pulley 3 and the synchronous belt 4. At the same time, since several transmission rollers 2 are set at an inclination, the steel pipe slides along the transmission roller 2 towards the output end under the action of the rotational power of the transmission roller 2 and its own gravity.

[0036] When the steel pipe slides to the end of the first support 1, it impacts the buffer plate 69 of the buffer assembly 6. The buffer pad first buffers the impact force of the steel pipe. At the same time, after the buffer plate 69 is impacted, it pushes the bearing shaft 61 to slide axially along the inner wall of the turntable 62. The bearing shaft 61 stretches the elastic reset member 66. The rebound force of the elastic reset member 66 offsets part of the impact force, realizing secondary buffering and avoiding damage to the end of the steel pipe.

[0037] After being buffered, the steel pipe remains at the output end of the transmission roller 2. The second motor 7 is started, and the second motor 7 drives the rotating shaft to rotate. The rotating shaft drives the spoon-shaped transfer block 8 to rotate. The spoon head of the transfer block 8 hooks the steel pipe. As the transfer block 8 continues to rotate, the spoon handle gradually overlaps on the guide slope 9. The steel pipe rolls along the spoon handle onto the guide slope 9 and slides down the guide slope 9 onto the bearing block 11 of the second support 10.

[0038] The third motor 121 is started. The third motor 121 drives one of the rotating wheels 122 to rotate through the rotating shaft. The rotating wheel 122 drives the other rotating wheel 122 to rotate synchronously through the synchronous pulley and synchronous belt. When the rotating wheel 122 rotates, it drives the eccentric shaft 123 to make a circular motion. The eccentric shaft 123 drives the bearing plate 125 to swing up and down through the connecting rod 124. When the bearing plate 125 swings upward, the friction protrusions on its surface contact the steel pipe and lift the steel pipe away from the bearing block 11. As the rotating wheel 122 continues to rotate, the bearing plate 125 drives the steel pipe to move in the direction of the guide ramp 13. When the bearing plate 125 swings downward, the steel pipe falls on the guide ramp 13 and slides quickly down the guide ramp 13 to the packaging area, completing the horizontal conveying process of the steel pipe. The bearing plate 125 then continues to swing, preparing to lift the next steel pipe that falls on the bearing block 11.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
