Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation, in particular to an environmentally friendly steel pipe continuous transportation device. Background Art

[0002] Steel pipes are prone to rust, scale, dust and other impurities during storage, transportation, bending and unloading, so they must be cleaned before use. Steel pipes are generally cleaned by pickling. The current traditional pickling method is to immerse bundles of steel pipes in an open acid tank using a hanger. The acid has a certain temperature. After a few tens of seconds of chemical reaction time, the hanger lifts the steel pipes and moves them horizontally to several adjacent rinsing tanks for immersion and rinsing, and then enters the plating agent tank for passivation treatment. The entire process equipment is simple, the operating environment is harsh, the output is low, and the energy consumption is high. This method has low investment, but there are many disadvantages, such as: environmental protection does not meet standards, pickling quality cannot be guaranteed, acid consumption is large, rinsing water consumption is large, and the degree of automation is extremely low.

[0057] like Figures 1 to 3As shown, the environmentally friendly steel pipe continuous conveying device 1 of the utility model includes a transition trough 10 and a stepping mechanism 20. The transition trough 10 includes a plurality of steel pipe trough bearing structures 11 arranged along a stepping direction X. The stepping mechanism 20 is used to convey the steel pipe carried on the transition trough 10 in a stepping manner along the stepping direction X. In detail, the stepping mechanism 20 is connected to the transition trough 10, and includes a stepping beam 100 and a stepping beam driving assembly 200. The stepping beam 100 includes a steel pipe beam bearing structure 110. The steel pipe beam bearing structure 110 is arranged corresponding to the steel pipe trough bearing structure 11 of the transition trough 10. The stepping beam driving assembly 200 drives the stepping beam 100 to rotate to drive the steel pipe to move and convey along the stepping direction X on the steel pipe trough bearing structure 11 of the transition trough 10.

[0058] When the utility model is applied to a steel pipe pickling production line, during the process of step-by-step transportation of the steel pipe along the steel pipe trough bearing structure 11 of the transition trough 10 by the stepping mechanism 20, not only can the continuous transportation of the steel pipe be realized, but also the liquid in the pickling, rinsing and plating-assisting links of the steel pipe in the previous process can be completely discharged, so as to avoid contamination of the liquid in the trough as the steel pipe enters the next process, and the liquid discharged from the steel pipe is collected by the transition trough 10 and can be recycled, thus saving energy.

[0059] Furthermore, the utility model drives the stepping beam 100 to rotate through the stepping beam driving assembly 200 to drive the steel pipe to move step by step along the stepping direction X on the steel pipe trough bearing structure 11 of the transition trough 10 to realize automatic continuous transportation without problems such as transportation jamming, impact, and discontinuity.

[0060] In some embodiments of the present invention, Figure 1 as well as Figure 4 and Figure 5 As shown, the environmentally friendly steel pipe continuous conveying device 1 also includes a turning mechanism 30, which is connected to the transition trough 10 and is used to turn the steel pipe over and convey it to the next process. Figure 6 The environmentally friendly steel pipe continuous conveying device 1 of the utility model is, for example, arranged between different first process equipment 2 and second process equipment 3 to realize the conveying of steel pipes between various process positions, and the process equipment at each process position is used to perform different process treatments on the steel pipes. It should be noted that the utility model is not limited to the steel pipe pickling industry, but can also be applied to other industries that require conveying.

[0061] In detail, the flip mechanism 30 includes a flip assembly 300 and a flip driving member, and the flip driving member drives the flip assembly 300 to flip around a flip axis P, wherein the flip assembly 300 is arranged corresponding to the front end of the steel pipe trough bearing structure 11 of the transition trough 10 along the stepping direction X. The axial direction of the flip axis P is perpendicular to the stepping direction X, and the flip assembly 300 is used to flip and transport the steel pipe carried on the steel pipe trough bearing structure 11 transported to the front end along the stepping direction X to the next process.

[0062] In some embodiments of the present invention, Figure 3 As shown, the walking beam driving assembly 200 includes a main driving shaft 210, a driven shaft 220 and a beam connector 230. The main driving shaft 210 and the driven shaft 220 are arranged in parallel, and the driven shaft 220 is connected to the walking beam 100 through the beam connector 230. The driving reduction motor of the walking beam driving assembly 200 can be connected to the transition groove 10 through a connecting seat. The main driving shaft 210 and the driven shaft 220 are driven by, for example, gear transmission, with high transmission efficiency and stability and low noise. The power is transmitted to the driven shaft 220 through the main driving shaft 210, and the driven shaft 220 drives the walking beam 100 to rotate through the beam connector 230.

[0063] Of course, in other embodiments, the walking beam driving assembly 200 may be used to directly drive the walking beam 100 to rotate, which is also within the protection scope of the present utility model.

[0064] Further, the driven shaft 220 includes a first driven shaft 221 and a second driven shaft 222 respectively arranged on both sides of the main driving shaft 210, and the beam connector 230 includes a front beam connector 231 and a rear beam connector 232.

The main driving shaft 210 is located between the first driven shaft 221 and the second driven shaft 222. The first driven shaft 221 and the second driven shaft 222 jointly drive the walking beam 100 to rotate, and the operation is more stable.

[0065] like Figure 4 and Figure 5As shown, in some embodiments of the environmentally friendly steel pipe continuous conveying device 1 of the utility model, the flip assembly 300 includes a swing rod 310, a connecting rod 320 and a flap 330, the middle part of the swing rod 310 is rotatably connected to the transition groove 10, the two ends of the connecting rod 320 are respectively connected to one end of the swing rod 310 and one end of the flap 330, the other end of the flap 330 is rotatably connected to the transition groove 10, and the flip driving member is arranged corresponding to the other end of the swing rod 310. The flip driving member presses the end of the swing rod 310 to lift the end of the swing rod 310 connected to the connecting rod 320, thereby driving the connecting rod 320 to push upward, and the end of the flap 330 connected to the connecting rod 320 rises together, and the flap 330 rotates around the end connected to the transition groove 10 with the flip axis P as the axis. The flip assembly 300 is arranged at the front end of the steel pipe trough bearing structure 11 along the stepping direction X, that is, the flap 330 lifts up the steel pipe transported to the front end along the stepping direction X and transports it to the next process. In the present invention, the flip drive member can be a separate driving component, such as a driving rod, which is arranged at the end of the swing rod 310 of the flip assembly 310. In some embodiments of the environmentally friendly steel pipe continuous conveying device 1 of the present invention, the walking beam driving assembly 200 can also serve as a flip driving member that drives the flip assembly 300.

[0066] In some embodiments of the environmentally friendly steel pipe continuous conveying device 1 of the utility model, Figure 1 , Figure 3 and Figure 4 As shown, there are multiple steel tube beam bearing structures 110 arranged in sequence along the stepping direction. The steel tube trough bearing structure 11 of the transition trough 10 is similar in structure to the steel tube beam bearing structure 110 of the stepping beam 100. The flipping assembly 300 is arranged in the gap between the steel tube beam bearing structure 110 and the steel tube trough bearing structure 11. The flipping assembly 300 flips and lifts up the steel pipe located on the steel tube trough bearing structure 11.

[0067] In the present invention, the steel tube beam bearing structure 110 and the steel tube groove bearing structure 11 are in a continuous broken line shape. Specifically, taking the steel tube beam bearing structure 110 as an example, the steel tube beam bearing structure 110 includes an inclined portion 111 and a limiting portion 112, and the inclined portion 111 and the limiting portion 112 are connected in an L shape, for example.

[0068] In some embodiments of the environmentally friendly steel pipe continuous conveying device 1 of the utility model, a slot cover 40 is further included, and the slot cover 40 is arranged on the transition tank 10. By setting the slot cover 40, the steel pipe can be semi-enclosedly conveyed through the environmentally friendly steel pipe continuous conveying device 1 of the utility model. Further, the slot cover 40 includes a pipe connection port 41. The utility model sets a pipe connection port 41 above the slot cover 40, which can be connected to a pipe, so as to facilitate the design of a negative pressure environment, absorb the acid mist emitted from the transition tank 10, uniformly treat the acid mist, and discharge it after passing the test, so as to achieve energy saving and environmental protection.

[0069] like Figures 7 to 10 The conveying steps of the environmentally friendly steel pipe continuous conveying device of the utility model are shown in the figure, combined with Figures 1 to 6 The reduction motor is connected to the driving shaft 210 through a coupling, and the reduction motor drives the driving shaft 210 to rotate, and drives the first driven shaft 221 and the second driven shaft 222 on both sides to rotate through gear transmission, and then drives the stepping beam 100 to rotate through the front beam connecting member 231 and the rear beam connecting member 232. Each rotation drives the steel pipe T to move once along the stepping direction X. Figures 7 to 9 As shown, the walking beam 100 rotates one circle to drive the steel pipe T to move from the steel pipe groove bearing structure 11-1 to the steel pipe groove bearing structure 11-2, thereby realizing the step-by-step conveying of the steel pipe T along the stepping direction X. It should be noted that the steel pipe T is not limited to a circular steel pipe, but can also be a rectangular pipe, a polygonal pipe, a special-shaped pipe, etc., all of which can be conveyed by the environmentally friendly steel pipe continuous conveying device 1 of the utility model.

[0070] like Figure 3 and Fig.10 As shown, in this embodiment, the stepping beam driving assembly 200 is used as the turning driving member for driving the turning assembly 300. Specifically, the front beam connecting member 231 includes a turning protrusion 231a, and the turning protrusion 231a is arranged corresponding to the other end of the swing rod 310 that is not connected to the connecting rod 320. When the stepping mechanism 20 conveys the steel pipe T to the last stage of the steel pipe groove bearing structure 11, the front beam connecting member 231 drives the swing rod 310 to rotate during the rotation process, and the swing rod 310 drives the flap 330 to rotate and lift through the connecting rod 320, so as to deliver the steel pipe T of the last stage to the toothed disc groove of the next process. After the turning assembly 300 completes the action, it returns to its original position by its own weight, and repeats the process. After the swing rod 310 of the utility model contacts with the front beam connecting member 231 to complete the turning action, the following protrusion 231a can use the cam curve to slow down the instantaneous impact force of the turning mechanism when it falls by its own weight, so that the flap can fall smoothly, avoiding the impact and noise on the environmentally friendly steel pipe pickling continuous conveying mechanism.

[0071] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
