Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe processing lines, and in particular to a waste pipe transfer device on a steel pipe processing line. Background Art

[0002] A steel pipe is a tubular object made of steel, commonly used as a pipeline for transporting fluids such as petroleum, natural gas, water, and gas. The production of steel pipes requires multiple processes such as cold drawing, cold rolling, and hot rolling. In a steel pipe processing line, the steel pipes are usually transferred through roller conveyors in each process. After completing the specified process, the steel pipes during the processing are inspected to ensure that the quality of the steel pipes meets the requirements. The waste pipes that do not meet the requirements need to be transferred out of the steel pipe processing line to prevent them from entering the next process.

[0003] Currently, the waste pipe transfer on a steel pipe processing line mainly transfers the waste pipes in the steel pipes longitudinally conveyed (conveyed along the axis direction of the steel pipe) on the conveyor roller of the steel pipe processing line to the platform rack for temporary storage through a direction-changing transfer structure. After the waste pipes accumulate to a certain amount, to ensure safety, the steel pipe processing line needs to be shut down, and then the waste pipes are lifted from the platform rack by a crane. Therefore, the existing waste pipe transfer device will also affect the processing efficiency of the steel pipe processing line while transferring the waste pipes. Summary of the Invention

[0004] The purpose of the present invention is to provide a waste pipe transfer device on a steel pipe processing line.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A waste pipe transfer device on a steel pipe processing line is provided on one side of the conveyor roller of the steel pipe processing line. It includes an inclined platform rack, an input transfer structure, an output transfer structure, a transfer roller conveyor, and several pipe dropping modules. An inclined platform rack is provided between the conveyor roller and the transfer roller conveyor. The conveyor roller forms a pipe feeding position corresponding to the inclined platform rack. The transfer roller conveyor forms a pipe inlet position corresponding to the inclined platform rack at one end and a pipe outlet position at the other end. The inclined platform rack forms a pipe feeding slope from high to low from the pipe feeding position to the pipe inlet position at the top, is provided with the input transfer structure at one end facing the pipe feeding position, and is provided with the output transfer structure at one end facing the pipe inlet position. The transfer roller conveyor is provided with the pipe dropping modules at intervals at the pipe outlet position, for the input transfer structure to convey the waste pipes from the pipe feeding position of the conveyor roller to the pipe feeding slope, and the waste pipes are conveyed along the pipe feeding slope. The output transfer structure can block the waste pipes on the pipe feeding slope and release the waste pipes one by one, and convey the waste pipes to the pipe inlet position of the transfer roller conveyor. The transfer roller conveyor conveys the waste pipes from the pipe inlet position to the pipe outlet position, and the pipe dropping modules output the waste pipes from the pipe outlet position to the ground.

[0007] As a further technical solution of the present invention: the output transfer structure includes several groups of output transfer modules, an output driving unit and a coherent shaft. The several groups of output transfer modules are spaced on one end of the inclined table frame facing the pipe inlet position. The output driving unit is provided with a first synchronous shaft below the pipe feeding inclined surface to drive the several groups of output transfer modules to operate synchronously by rotation;

[0008] Each output transfer module includes a fixed frame arranged below the pipe feeding inclined surface, a blocking inner arm that can swing and is arranged between the pipe feeding inclined surface and the fixed frame, a transmission middle arm and a transfer outer arm; the blocking inner arms of several groups of output transfer modules are connected at one end adjacent to the transmission middle arm by a coherent shaft. The bottom of the blocking inner arm is hinged to the fixed frame, and a blocking part is formed at the top of the blocking inner arm that can rise and fall relative to the pipe feeding inclined surface as it swings; one end of both the transmission middle arm and the transfer outer arm is installed on the first synchronous shaft. The other end of the transmission middle arm extends towards the blocking inner arm and forms a U-shaped opening for the coherent shaft to pass through. The other end of the transfer outer arm extends towards the pipe inlet position and forms a pipe lifting guiding edge that can rise and fall relative to the top of the transfer roller path as it swings. The output driving unit drives the first synchronous shaft to rotate. The first synchronous shaft drives the transmission middle arm and the transfer outer arm to rise and fall. The transmission middle arm presses against the coherent shaft with the U-shaped opening to drive the blocking inner arm to rise and fall.

[0009] As a further technical solution of the present invention: the input transfer structure includes several input swing arms and an input driving unit. The input driving unit is provided with a second synchronous shaft below the pipe feeding inclined surface. The several input swing arms are spaced on one end of the inclined table frame facing the pipe feeding position. One end of each input swing arm is installed on the second synchronous shaft. The other end of the input swing arm extends towards the pipe feeding position and forms a pipe feeding guiding edge that can rise and fall relative to the top of the conveyor roller path as it swings. The input driving unit drives the second synchronous shaft to rotate, driving the input swing arms to lift, and uses the pipe feeding guiding edge to lift the waste pipe from the conveyor roller path. After being lifted, the waste pipe falls onto the pipe feeding inclined surface along the input swing arms.

[0010] As a further technical solution of the present invention: the pipe dropping module includes a fixed seat, a fulcrum shaft, a pipe lifting swing arm and a pipe dropping swing arm; the fulcrum shaft is arranged in the pipe dropping side of the conveying roller seat at the pipe outlet position in the same conveying direction as the transfer roller path, and one end of it is rotatably installed below the top of the transfer roller path through the fixed seat; one end of both the pipe lifting swing arm and the pipe dropping swing arm is installed on the other end of the fulcrum shaft and can swing with the fulcrum shaft as the rotation fulcrum. The other end of the pipe lifting swing arm extends towards the direction where the transfer roller path is located and forms a pipe supporting guiding edge that can rise and fall relative to the top of the transfer roller path as it swings; the other end of the pipe dropping swing arm extends towards the pipe dropping direction and forms a pipe dropping guiding edge that can rise and fall relative to the ground as it swings.

[0011] As a further technical solution of the present invention: The pipe dropping module includes a pipe dropping driving cylinder and two traction rods; the pipe dropping driving cylinder is obliquely arranged on the other side of the transfer roller path, and the telescopic rod of the pipe dropping driving cylinder faces the fulcrum shaft and is hinged to the bottom ends of the two traction rods. The top end of one traction rod is hinged to the middle section of the pipe lifting swing arm, and the top end of the other traction rod is hinged to the middle section of the pipe dropping swing arm, for the telescopic rod of the pipe dropping driving cylinder to stretch and retract, and the two traction rods provide the driving force for the rotation and swing of the pipe lifting swing arm and the pipe dropping swing arm.

[0012] As a further technical solution of the present invention: When the telescopic rod of the pipe dropping driving cylinder extends, the pipe lifting swing arm swings upward from below the top of the transfer roller path to above, and the waste pipe is lifted from the pipe outlet position by the pipe guiding edge. The pipe dropping swing arm swings upward from a position adjacent to the ground to above the ground, and the waste pipe transitions along the pipe guiding edge to the pipe dropping guiding edge. As the telescopic rod of the pipe dropping driving cylinder retracts, the pipe lifting swing arm and the pipe dropping swing arm reset, and the waste pipe is taken to the ground by the pipe dropping guiding edge.

[0013] As a further technical solution of the present invention: The output driving unit uses a telescopic driving cylinder to provide the driving force for the rotation of the first synchronizing shaft. A push-pull block is hinged to the driving rod of the telescopic driving cylinder, and the push-pull block is installed on the first synchronizing shaft, for the driving rod of the telescopic driving cylinder to stretch and retract, driving the push-pull block to swing, so as to drive the first synchronizing shaft to rotate.

Each unit frame is provided with a number of support columns at intervals between the pipe feeding position and the pipe inlet position. The unit frame is provided with a table top rod on the top of the number of support columns, which is inclined from high to low from the pipe feeding position to the pipe inlet position.

[0016] As a further technical solution of the present invention: The conveying roller path and the transfer roller path both include a number of conveying roller seats arranged at intervals. Each conveying roller seat includes a seat body, a conveying roller rotatably installed on the top of the seat body, and a driving motor for driving the conveying roller to rotate.

The waste pipe is conveyed and stored along the pipe feeding inclined plane 201. The output transfer structure 40 blocks the waste pipe with the blocking inner arm 412 and can input the waste pipe into the pipe inlet position 51 of the transfer roller path 50 with the transfer outer arm 414. The transfer roller path 50 conveys the waste pipe from the pipe inlet position 51 to the pipe outlet position 52. The pipe dropping module 60 outputs the waste pipe from the pipe outlet position 52 to the ground. Subsequently, the waste pipe is lifted away from the ground by a crane.

[0029] Further, in this embodiment, with reference to Figure 4, the input transfer structure 30 includes a plurality of input swing arms 31 and an input driving unit 32. The input driving unit 32 is provided with a second synchronizing shaft 321 below the pipe feeding inclined plane 201. The plurality of input swing arms 31 are spaced at one end of the inclined platform 20 facing the pipe feeding position 11. One end of each input swing arm 31 is mounted on the second synchronizing shaft 321. The other end of the input swing arm 31 extends towards the pipe feeding position 11 and is formed with a pipe feeding guiding edge 311 that rises and falls relative to the top of the conveying roller path 10 as it swings. The input driving unit 32 drives the second synchronizing shaft 321 to rotate, driving the input swing arm 31 to lift, and the waste pipe is lifted from the conveying roller path 10 by the pipe feeding guiding edge 311, and the lifted waste pipe can fall onto the pipe feeding inclined plane 201 along the input swing arm 31.

[0030] Further, in this embodiment, both the output driving unit 42 and the input driving unit 32 use a telescopic driving cylinder 71 to provide the driving force for the rotation of the first synchronizing shaft 421 or the second synchronizing shaft 321. A push-pull block is hinged on the driving rod of the telescopic driving cylinder 71, and the push-pull block is mounted on the first synchronizing shaft 421 or the second synchronizing shaft 321. The driving rod of the telescopic driving cylinder 71 is extended and retracted to drive the push-pull block to swing, so as to drive the first synchronizing shaft 421 or the second synchronizing shaft 321 to rotate.

[0031] Further, in this embodiment, the fixed frame 411 is provided with a first bearing seat 72 for the first synchronizing shaft 421 to pass through, and the first synchronizing shaft 421 is rotatably arranged between the pipe feeding inclined plane 201 and the fixed frame 411.

[0032] Further, in this embodiment, brackets 73 are spaced below the pipe feeding inclined plane 201 at one end of the inclined platform 20 facing the pipe feeding position 11. The brackets 73 are provided with second bearing seats 731 for the second synchronizing shaft 321 to pass through, and the second synchronizing shaft 321 is rotatably arranged between the pipe feeding inclined plane 201 and the brackets 73.

[0033] Further, in this embodiment, the inclined platform 20 includes a plurality of unit frames 21 spaced along the steel pipe conveying direction. Each unit frame 21 is spaced with a plurality of support columns 211 between the pipe feeding position 11 and the pipe inlet position 51. The unit frame 21 is provided with a table surface rod 212 that is inclined from high to low from the pipe feeding position 11 to the pipe inlet position 51 at the tops of the plurality of support columns 211. Among them, the fixed frame 411 is mounted on the support column 211 adjacent to the pipe feeding position 11, and the bracket 73 is mounted on the support column 211 adjacent to the pipe inlet position 51.

[0034] Further, in this embodiment, both the transfer roller path 10 and the transfer roller path 50 include a plurality of conveying roller seats 81 arranged at a linear interval along the steel pipe conveying direction or the waste pipe conveying direction. Each conveying roller seat 81 includes a seat body 811 and a conveying roller 812 rotatably mounted on the top of the seat body 811. A driving motor 813 for driving the conveying roller 812 to rotate is provided on some of the conveying roller seats 81, and the conveying roller 812 is preferably in an hourglass shape, so that while conveying the steel pipe, the groove in the middle of the conveying roller 812 limits the steel pipe.

[0035] Further, in this embodiment, with reference to Figure 5 , Figure 6 and Figure 7 , the pipe dropping module 60 includes a fixed seat 61, a fulcrum shaft 62, a pipe lifting swing arm 63, a pipe dropping swing arm 64, a pipe dropping driving cylinder 65 and two traction rods 66; the fulcrum shaft 62 is arranged in the pipe dropping side of the conveying roller seat 81 at the pipe outlet position 52 in the same direction as the conveying direction of the transfer roller path 50, and one end of it is rotatably mounted below the top of the conveying roller seat 81 through the fixed seat 61; both the pipe lifting swing arm 63 and the pipe dropping swing arm 64 are mounted at the other end of the fulcrum shaft 62 with one end, and can swing with the fulcrum shaft 62 as the rotation fulcrum. The other end of the pipe lifting swing arm 63 extends towards the direction where the conveying roller seat 81 is located and forms a pipe supporting guiding edge 631 that can rise and fall relative to the top of the conveying roller seat 81 as it swings; the other end of the pipe dropping swing arm 64 extends towards the pipe dropping direction and forms a pipe dropping guiding edge 641 that can rise and fall relative to the ground as it swings; the pipe dropping driving cylinder 65 is obliquely arranged on the other side of the conveying roller seat 81, and the telescopic rod of the pipe dropping driving cylinder 65 is arranged towards the fulcrum shaft 62 and is hinged to the bottom ends of the two traction rods 66. The top end of one traction rod 66 is hinged to the middle section of the pipe lifting swing arm 63, and the top end of the other traction rod 66 is hinged to the middle section of the pipe dropping swing arm 64, so that the telescopic rod of the pipe dropping driving cylinder 65 can stretch, and the two traction rods 66 provide the driving force for the pipe lifting swing arm 63 and the pipe dropping swing arm 64 to swing. Specifically, when the telescopic rod of the pipe dropping driving cylinder 65 extends, the pipe lifting swing arm 63 swings from below the top of the conveying roller seat 81 to above, and the waste pipe is lifted from the pipe outlet position 52 with the pipe supporting guiding edge 631. The pipe dropping swing arm 64 swings from a position adjacent to the ground to above the ground, and the waste pipe transitions from the pipe supporting guiding edge 631 to the pipe dropping guiding edge 641. As the telescopic rod of the pipe dropping driving cylinder 65 retracts, the pipe lifting swing arm 63 and the pipe dropping swing arm 64 reset, and the waste pipe is taken to the ground with the pipe dropping guiding edge 641.

[0036] Further, in this embodiment, the pipe lifting guiding edge 403, the pipe feeding guiding edge 311 and the pipe supporting guiding edge 631 all form a bottom edge near the hinge and a baffle edge connected to the bottom edge at a position far from the hinge, and the angle between the bottom edge and the baffle edge is an obtuse angle.

[0037] Further, in this embodiment, the guiding edge 641 of the dropping pipe is in a shape of a reversed L formed by connecting multiple straight edges end to end, so as to drop the waste pipe onto the ground.

[0038] Further, in this embodiment, the fixed seat 61 is installed on the seat body 811 of the conveying roller seat 81 at the pipe outlet position 52.

[0039] Further, in this embodiment, a buffer blocking seat 501 is provided at the end of the transfer roller path 50 at the pipe outlet position 52 for blocking the waste pipe.

[0040] It can be understood that the waste pipe transfer method of the waste pipe transfer device on a steel pipe processing line of the present invention is as follows: when the steel pipe processing line detects a waste pipe, when the waste pipe is conveyed to the pipe feeding position 11 of the conveying roller path 10, the input transfer structure 30 is started, and the input driving unit 32 drives a plurality of input swing arms 31 to swing from below the top of the conveying roller path 10 to above, and the waste pipe is lifted from the conveying roller path 10 by the pipe feeding guiding edge 311. The lifted waste pipe falls onto the pipe feeding inclined plane 201 along the input swing arm 31, and then is conveyed to the pipe inlet position 51 along the pipe feeding inclined plane 201. When the output transfer structure 40 is not started, the blocking part 401 of the blocking inner arm 412 penetrates out to the pipe feeding inclined plane 201 to block and store the waste pipe on the pipe feeding inclined plane 201, realizing the transfer of the waste pipe from the conveying roller path 10 to the inclined table frame 20.

[0041] When the waste pipe needs to be transferred externally from the inclined table frame 20, the output transfer structure 40 is started, the telescopic rod of the telescopic driving cylinder 71 of the output driving unit 42 expands and contracts to drive the first synchronous shaft 421 to rotate back and forth. First, the blocking part 401 of the blocking inner arm 412 descends below the pipe feeding inclined plane 201, and the transfer outer arm 414 swings from below the top of the transfer roller path 50 to above to support the waste pipe continuously output from the pipe feeding inclined plane 201 with the pipe lifting guiding edge 403. Then, the blocking part 401 of the blocking inner arm 412 rises to reset to continue blocking the remaining waste pipes, while the transfer outer arm 414 swings from above the top of the transfer roller path 50 to below, and the waste pipe falls into the pipe inlet position 51 of the transfer roller path 50; subsequently, the transfer roller path 50 conveys the waste pipe from the pipe inlet position 51 to the pipe outlet position 52, and the dropping pipe module 60 outputs the waste pipe at the pipe outlet position 52 to the ground, and the waste pipe is lifted away from the ground by a crane, realizing the external transfer of the waste pipe.

[0042] In summary, the waste pipe transfer device on a steel pipe processing line of the present invention can transfer multiple waste pipes from the conveying roller path 10 to the inclined table frame 20 for storage and transfer the waste pipes from the inclined table frame 20 to the ground one by one through the cooperation between the inclined table frame 20, the input transfer structure 30, the output transfer structure 40, the transfer roller path 50 and a plurality of dropping pipe modules 60, without stopping the steel pipe processing line, and can effectively improve the processing efficiency of the steel pipe processing line.

[0043] Any combination of various different embodiments of the present invention shall be regarded as the content disclosed in the present invention as long as it does not violate the idea of the present invention; within the scope of the technical concept of the present invention, various simple modifications of the technical solutions and any combination of different embodiments that do not violate the idea of the present invention shall fall within the protection scope of the present invention.
