Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe processing devices, and specifically relates to a spiral steel pipe conveying device. Background Art

[0002] A spiral steel pipe conveying device is a device used to convey spiral steel pipes from one position to another. The purpose is to realize the orderly transfer of spiral steel pipes in production processes such as processing and detection, so as to meet the requirements of subsequent processes for the positions of spiral steel pipes, improve production efficiency, and ensure the continuity and stability of the production process.

[0003] Currently, after the spiral steel pipe is processed in the previous process, it usually needs to be stacked on a platform for cooling and placement. After cooling, subsequent detection or other processing operations can be carried out. Since the current conveying devices are relatively simple and generally use belt, chain or roller conveyors, when the spiral steel pipe enters the next process after cooling, it is usually not easy to realize automatic intermittent feeding and conveying. Using manual methods is undoubtedly time-consuming and laborious, and the spiral steel pipe is relatively heavy, which is not conducive to the physical health of workers. The common solution in the existing technology is to install a robotic arm at this position and use the robotic arm to gradually clamp and transfer the spiral steel pipe. This method has the following deficiencies: First, the robotic arm needs multiple power sources to drive each joint and action for clamping and transferring the spiral steel pipe. The structure of the robotic arm is complex, the cost is high, and after long-term operation, the transmission parts are prone to wear, the failure rate is high, and the maintenance cost is high; Second, during the clamping process of the robotic arm, it usually needs to cooperate with sensing elements and a control system to ensure accurate clamping and shifting operations to achieve the intermittent conveying of spiral steel pipes.

[0022] By providing a spiral steel pipe conveying device in the embodiments of the present application, the problems in the existing spiral steel pipe conveying device during transfer using a robotic arm structure are solved. The robotic arm structure is complex and costly, and there are many mechanical drive units in the robotic arm.

During the clamping process of the robotic arm, a sensing element and a control system are usually required to ensure precise clamping and displacement operations to achieve the intermittent conveying of spiral steel pipes. Since there are many types of spiral steel pipes, the control system design is complex, prone to failures, and requires regular updates and maintenance.

[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners. Embodiment

[0024] An embodiment of the present invention discloses a spiral steel pipe conveying device. As shown in the attached Figure 1-8 figures, it includes a placement platform 100, an intermittent conveying platform 200, a hollow groove 300, a column 1, a fixed platform 2, a lifting drive unit 3, a lifting platform 4, a lifting seat 5, a lever 7, and a transmission unit 10; The placement platform 100 is arranged on the ground at the target position and is used for temporarily storing spiral steel pipes; the placement platform 100 is used for placing the semi-finished products of fixed-length spiral steel pipes after preliminary processing, so that multiple groups of semi-finished products of spiral steel pipes are arranged together for cooling and placement, thus facilitating the subsequent inspection. The intermittent conveying platform 200 is arranged on the ground at the target position and is connected to the placement platform 100; the intermittent conveying platform 200 and the placement platform 100 are integrally formed and are supported by support legs at the bottom for overhead support. After multiple groups of semi-finished products of spiral steel pipes are arranged together for cooling and placement, the multiple groups of semi-finished products of spiral steel pipes are transferred from the placement platform 100 to the intermittent conveying platform 200 to achieve intermittent conveying, so that multiple groups of semi-finished products of spiral steel pipes gradually enter the next component.

[0025] The hollow groove 300 is provided on the placement platform 100 and the intermittent conveying platform 200; the hollow groove 300 is used to provide installation space for the lifting platform 4, the lifting seat 5, the lever 7 and the transmission unit 10, so that when the lifting drive unit 3 drives the lifting platform 4 and the lifting seat 5 to move upward, the lifting seat 5 lifts the spiral steel pipe. After lifting to the target height, the transmission unit 10 drives the lever 7 to move and push the spiral steel pipe, so that the spiral steel pipe enters the intermittent conveying platform 200. Each lifting action of the lifting drive unit 3 drives a group of spiral steel pipes to move, thereby realizing the periodic transportation of the spiral steel pipes and realizing the subsequent continuous processing operation of the spiral steel pipes. The column 1 is arranged at the bottom of the placement platform 100 ; the column 1 is used to support and fix the fixing platform 2 .

[0026] The fixing platform 2 is arranged at the bottom of the column 1; the fixing platform 2 is used to provide a mounting platform for the lifting drive unit 3, so that the installation of the lifting drive unit 3 is stable.

[0027] The lifting drive unit 3 is arranged on the fixed platform 2; the lifting drive unit 3 can adopt an electric push rod or other device with a lifting function, and the lifting drive unit 3 is used to conveniently drive the lifting platform 4 to perform lifting actions.

[0028] The lifting platform 4 is arranged at the output end of the lifting drive unit 3; the lifting platform 4 is used to support and limit the lifting seat 5, so that the lifting seat 5 can be lifted and lowered synchronously. When the lifting seat 5 is lifted and lowered, the lifting seat 5 is used to lift the spiral steel pipe.

[0029] The lifting seat 5 is arranged on the lifting platform 4 and is used to lift the spiral steel pipe; the lifting seat 5 is provided with a notch for engaging the spiral steel pipe, so that the force is stable when the spiral steel pipe is lifted; The lever 7 is arranged on the side of the lifting seat 5 and is used to move the spiral steel pipe; after the lifting seat 5 lifts the spiral steel pipe to the target height, the lever 7 rotates to push the spiral steel pipe away from the lifting seat 5 and enter the intermittent conveying platform 200, thereby realizing the conveying of the spiral steel pipe; The transmission unit 10 is arranged between the fixed platform 2 and the lifting platform 4 and is used to drive the lever 7 to move with the lifting power of the lifting platform 4. Through the design of the transmission unit 10, the lever 7 does not need to provide an additional power source, and the lifting action of the spiral steel pipe is directly linked through the lifting platform 4 and the lifting seat 5, thereby reducing the design of power components, reducing the complexity of the circuit, ensuring the synchronization of the lifting and lateral movement of the spiral steel pipe, making the conveying process of the spiral steel pipe stable, and further ensuring the stability of the intermittent conveying process of the spiral steel pipe, making the subsequent processing and testing process of the spiral steel pipe stable.

[0030] A lateral support rod 6 is provided at the bottom of the lifting platform 4, and the lateral support rod 6 is slidably connected to the fixed platform 2. The lateral support rod 6 provides lateral support for the lifting platform 4. When the lifting platform 4 is lifted or lowered, the lifting platform 4 drives the lateral support rod 6 to move, and the lateral support rod 6 moves along the fixed platform 2, thereby making the lifting platform 4 stable in force, and not easy to deviate during the movement process, ensuring stable operation of the device.

[0031] The transmission unit 10 comprises: The first transmission shaft 11 is rotatably connected to the lifting platform 4 and is used to support and limit the shifting rod 7; A first sprocket 12 is disposed on the first transmission shaft 11; A second transmission shaft 13 is rotatably connected to the lateral support rod 6; The rack 14 is fixedly connected to the bottom of the fixed platform 2; A gear 15, disposed on the second transmission shaft 13 and meshing with the rack 14; A second sprocket 16 is disposed on the second transmission shaft 13; The chain 17 is sleeved on the first sprocket 12 and the second sprocket 16 .

[0032] The transmission unit 10 designed in the device has a compact structure and stable operation. When the lifting platform 4 and the lifting seat 5 move under the drive of the lifting drive unit 3, the lifting platform 4 drives the lateral support rod 6 to move synchronously, and the lifting platform 4 drives the first transmission shaft 11, the first sprocket 12 and the lever 7 to perform lifting and lowering movements. The lateral support rod 6 drives the second transmission shaft 13, the gear 15 and the second sprocket 16 to perform lifting and lowering movements. When the gear 15 moves, it moves relative to the rack 14, so the rack 14 drives the gear 15 to rotate; The gear 15 rotates synchronously during the lifting process. Therefore, the gear 15 synchronously drives the second transmission shaft 13 to rotate, the second transmission shaft 13 drives the second sprocket 16 to rotate, the second sprocket 16 drives the chain 17 to rotate, the chain 17 drives the first sprocket 12 to rotate, the first sprocket 12 drives the first transmission shaft 11 to rotate, the first transmission shaft 11 drives the lever 7 to rotate, and the lever 7 finally drives the spiral steel pipe to move from the lifting seat 5 to the intermittent conveying platform 200, and then the intermittent conveying platform 200 is used to transport the spiral steel pipe horizontally to the next component for processing or testing. Example

[0033] The embodiment of the present invention discloses a spiral steel pipe conveying device. Figure 1-8 As shown, it includes a placement platform 100, an intermittent conveying platform 200, a hollow slot 300, a column 1, a fixing platform 2, a lifting drive unit 3, a lifting platform 4, a lifting seat 5, a lever 7 and a transmission unit 10; The placement platform 100 is set on the ground at the target location and is used to temporarily store the spiral steel pipe; The intermittent conveying platform 200 is disposed on the ground at the target location and connected to the placement platform 100; The hollow groove 300 is provided on the placement platform 100 and the intermittent conveying platform 200; The column 1 is arranged at the bottom of the placement platform 100; The fixing platform 2 is arranged at the bottom of the column 1; The lifting drive unit 3 is arranged on the fixed platform 2; The lifting platform 4 is arranged at the output end of the lifting drive unit 3; The lifting seat 5 is arranged on the lifting platform 4 and is used to lift the spiral steel pipe; The lever 7 is arranged on the side of the lifting seat 5 and is used to move the spiral steel pipe; The transmission unit 10 is disposed between the fixed platform 2 and the lifting platform 4 and is used to drive the lever 7 to move with the lifting power of the lifting platform 4 .

[0034] The lifting platform 4 is provided with a limit seat 41, and the lifting seat 5 is provided with a clamping block 51, which is movably inserted in the limit seat 41, and the limit seat 41 is provided with a locking unit 20 for limiting the clamping block 51. The device facilitates the model change of the lifting seat 5 through the design of the limit seat 41, the clamping block 51 and the locking unit 20, thereby ensuring that the lifting seat 5 can lift spiral steel pipes of different pipe diameters and models, and ensuring the transportation stability of the spiral steel pipes.

[0035] The block 51 is provided with a locking hole 511, and the locking unit 20 includes: The guide rail frame 21 is arranged on the limit seat 41; The adjusting platform 22 is movably connected to the guide rail frame 21; The locking rod 23 is disposed on the adjusting platform 22 and passes through the limiting seat 41 to be movably inserted into the locking hole 511 .

[0036] A screw rod 24 is threadedly connected to the guide rail frame 21 , and the screw rod 24 is rotatably connected to the adjustment platform 22 .

[0037] The locking unit 20 has a simple structure, which facilitates the rapid locking operation after the lifting seat 5 and the lifting platform 4 are connected. After locking, the connection is stable and not easy to loosen, thereby making the connection between the lifting platform 4 and the lifting seat 5 stable, ensuring the subsequent stable transportation of the spiral steel pipe. When it is necessary to quickly dock the lifting platform 4 and the lifting seat 5, first select a lifting seat 5 with a suitable size and shape according to the diameter of the spiral steel pipe, then dock and snap the limit seat 41 and the clamping block 51. After complete snapping, rotate the lead screw 24. At this time, the lead screw 24 moves spirally along the guide rail frame 21 and pushes the adjustment table 22 to move. While the adjustment table 22 moves along the guide rail frame 21, it drives the locking rod 23 to move. Finally, the locking rod 23 is inserted into the inside of the locking hole 511, thereby realizing the locking after the positions of the limit seat 41 and the clamping block 51 are snapped. Therefore, the lifting platform 4 and the lifting seat 5 are quickly docked and locked. When it is necessary to disassemble the lifting platform 4 and the lifting seat 5 and replace the model of the lifting seat 5, the process of disassembling the lifting seat 5 is just the reverse of the above process of installing the lifting seat 5.
