Description

Technical Field

[0001] This invention relates to a steel pipe rinsing mechanism in the field of steel pipe processing, specifically to an automatic steel pipe feeding and pre-rinsing mechanism. Background Technology

[0002] Steel pipes are widely used in modern society, such as in the petrochemical industry and heat exchangers. In conventional production, the inner and outer surfaces of steel pipes need to be cleaned and pre-washed. However, due to the large net weight and length of steel pipes, the operation of loading and cleaning them is very cumbersome. Traditional loading methods involve manual loading by a single operator, which is physically demanding, prone to fatigue, increases manpower requirements, raises company operating costs, and is prone to safety accidents. Alternatively, bundles of steel pipes are placed on a loading rack, laid flat, and slowly lowered by the rack's incline and the pipes' own weight. This often results in multiple pipes being loaded at once, causing them to pile up together. Summary of the Invention

[0003] To address the problems and needs in the background technology, this invention provides an automatic steel pipe feeding and pre-rinsing mechanism, which achieves stable and orderly steel pipe feeding, while also treating dust and dirt on the surface of the steel pipe, thereby improving work efficiency.

[0019] This invention proposes an automatic steel pipe feeding mechanism. The steel pipe unloading mechanism controls the number of steel pipes entering the production line, ensuring the feeding speed and interval, and also providing a buffer for the steel pipe delivery. The automatic rotating mechanism controls the position and rhythm of the steel pipes entering the production line through the lifting and lowering of the double-position flip-plate, ensuring smooth and orderly feeding. The pre-rinsing mechanism uses spray guns to clean the surface dust and rust of the steel pipes. The automatic rotating mechanism uses a rotating nylon wheel to precisely rub and roll the steel pipes, ensuring thorough cleaning and improving work efficiency. Attached Figure Description

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figure 1 As shown, the present invention includes a steel pipe feeding mechanism, a steel pipe conveying mechanism, a steel pipe automatic rotation mechanism, and a steel pipe washing mechanism; the steel pipe feeding mechanism is connected to the steel pipe conveying mechanism, the steel pipe conveying mechanism is connected to the steel pipe automatic rotation mechanism, and a steel pipe washing mechanism is installed above the steel pipe automatic rotation mechanism; steel pipes are placed on the steel pipe feeding mechanism, and each steel pipe is transported to the steel pipe automatic rotation mechanism via the steel pipe feeding mechanism and the steel pipe conveying mechanism; the steel pipe automatic rotation mechanism is used to place each steel pipe below the steel pipe washing mechanism, so that each steel pipe is rotated and washed below the steel pipe washing mechanism.

[0039] like Figure 3 and Figure 4 As shown, the steel pipe feeding mechanism includes multiple steel pipe feeding assemblies, a discharge arm shaft 7, a second bearing with a square seat 58, a discharge cylinder arm plate 59, and a discharge lifting cylinder 60. The multiple steel pipe feeding assemblies are arranged sequentially and at intervals along the axial direction of the steel pipe, that is, the arrangement direction of the multiple steel pipe feeding assemblies is parallel to the axial direction of the steel pipe. The chain head fixing column 1 of each steel pipe feeding assembly is also connected to the feeding chain sub-shaft 2 of the corresponding steel pipe transmission assembly of the steel pipe transmission mechanism. A flap cylinder frame 152 is installed on the side of the outermost steel pipe feeding assembly. The flap cylinder frame 152 is used to isolate water. The discharge lifting cylinder 60 is fixedly installed on the side of the flap cylinder frame 152 away from the steel pipe feeding assembly. The output shaft of the discharge lifting cylinder 60 is connected to the discharge arm through the discharge cylinder arm plate 59. One end of the shaft 7 is connected to the discharge lifting cylinder 60, which converts the reciprocating motion of the discharge arm 60 into rotational motion through the discharge cylinder arm plate 59. The discharge arm shaft 7 is installed in the flip cylinder frame 152 through the second square seat bearing 58. The other end of the discharge arm shaft 7 passes through the flip cylinder frame 152 and is installed in the corresponding chain column 9 through the first square seat bearing 8, and is fixedly connected to the corresponding discharge curved arm plate 5, thereby connecting to multiple steel pipe feeding assemblies. Steel pipes are stably placed on the multiple steel pipe feeding assemblies. The discharge lifting cylinder 60 drives the discharge arm shaft 7 to rotate, which in turn drives the discharge curved arm plate 5 and the discharge U plate 4 in the multiple steel pipe feeding assemblies to move, thereby driving the discharge arm 3 to move up and down, so that the steel pipes are transported to the steel pipe transmission mechanism in sequence.

[0040] The power of the discharge lifting cylinder is transmitted to the mechanism by rotating the discharge arm shaft 7 through the rotation of the discharge cylinder arm plate 59. At the same time, the power on the discharge arm shaft 7 is also transmitted to the discharge arm 3 through the rotation of the discharge curved arm plate 5 and the movement of the discharge U plate 4, so that the discharge arm 3 can rise and fall regularly according to the movement rhythm of the cylinder, thereby controlling the number of steel pipes to be washed entering the equipment.

[0041] like Figure 5 and Figure 6 As shown, each steel pipe feeding assembly includes a cylindrical hole self-aligning ball bearing 57, a fourth belt vertical seat bearing 53, a chain head fixing column 1, a feeding arm 3, a first belt square seat bearing 8, and a chain middle column 9. The chain head fixing column 1 is connected to the feeding chain sub-shaft 2 of the corresponding steel pipe conveying assembly in the steel pipe conveying mechanism. Along the axial direction perpendicular to the steel pipe, i.e. the conveying direction of the steel pipe, the chain head fixing column 1 and the chain middle column 9 are installed in sequence. One end of the feeding arm 3 is connected to the chain head fixing column 1. In specific implementation, one end of the feeding arm 3 is connected to the chain head fixing column 1 through the feeding chain sub-shaft 2. Specifically, both ends of the feeding chain sub-shaft 2 extend out of the chain head fixing column 1 and are connected to the corresponding fourth belt vertical seat bearing 53. One end of the feeding arm 3 is fixedly installed on the corresponding fourth belt vertical seat bearing 53. The feeding arm shaft 7 is installed in the chain column 9 via the first square seat bearing 8. The feeding arm shaft 7 in the first square seat bearing 8 is also equipped with a cylindrical hole self-aligning ball bearing 57 to stabilize the rotation of the feeding arm shaft 7. The other end of the feeding arm 3 is connected to the feeding arm shaft 7 via the feeding drive arm. The feeding arm shaft 7 drives the other end of the feeding arm 3 to move up and down via the feeding drive arm. Under the initial working condition, the end of the feeding arm 3 near the chain column 9 is higher than the end near the chain head fixed column 1.

[0042] The material feeding drive arm includes a material feeding U-plate 4 and a material feeding curved arm plate 5. One end of the material feeding U-plate 4 is hinged to the other end of the material feeding arm 3, and the other end of the material feeding U-plate 4 is hinged to one end of the material feeding curved arm plate 5. The other end of the material feeding curved arm plate 5 is fixedly connected to the material feeding arm shaft 7 through a tensioning connecting sleeve 6.

[0043] like Figure 2 , Figure 7 and Figure 8As shown, the steel pipe conveying mechanism includes multiple steel pipe conveying components, a chain drive shaft 12, and a conveying chain working motor 61. The conveying chain working motor 61 is fixedly installed on the side of the flip-plate cylinder frame 152 away from the steel pipe feeding components. The output shaft of the conveying chain working motor 61 is coaxially and fixedly connected to the chain drive shaft 12. The multiple steel pipe conveying components are arranged sequentially and spaced apart along the steel pipe axis. The axis of the chain drive shaft 12 is parallel to the steel pipe axis. The chain drive shaft 12 is sequentially connected to the first feeding gear 15 corresponding to the multiple steel pipe conveying components. The feeding chain secondary shaft 2 of the multiple steel pipe conveying components is connected to the chain head fixed column 1 of the corresponding steel pipe feeding component in the steel pipe feeding mechanism. The conveying chain working motor 61 drives the chain drive shaft 12 to rotate, and the chain drive shaft 12 drives the steel pipes on the multiple steel pipe conveying components to be transported to the automatic steel pipe rotating mechanism.

[0044] Each steel pipe conveying assembly includes a feeding chain sub-shaft 2, a first bearing with a square seat 31, a steel pipe unloading chain 10, a chain tail fixing column 13, a first bearing with a vertical seat 14, a first feeding gear 15, a steel pipe support arm 29, a second feeding gear 52, and a conveying chain working motor 61. The second feeding gear 52 is installed in the chain head fixing column 1 of the corresponding steel pipe feeding assembly through the feeding chain sub-shaft 2 and the first bearing with a square seat 31. The chain tail fixing column 13 and the chain head fixing column 1 of the corresponding steel pipe feeding assembly are arranged along the steel pipe conveying direction. The chain drive shaft 12 is installed in the chain tail fixing column 13 through the first bearing with a vertical seat 14. The chain drive shaft 12 is sleeved with the first feeding gear 15. The second feeding gear 52 and the first feeding gear 15 are sleeved with the steel pipe unloading chain 10. The second feeding gear 52, the first feeding gear 15, and the steel pipe unloading chain 10 form a conveying structure. A steel pipe support arm 29 extending to the automatic rotating mechanism of the steel pipe is provided on the chain tail fixed column 13.

[0045] The power of the conveyor chain motor is transmitted to the entire steel pipe conveying mechanism through the rotation of the chain drive shaft 12, which drives the feeding gear 15 to rotate, and in turn drives the steel pipe conveying chain 10 to move. The steel pipe to be washed enters the steel pipe conveying chain 10 after passing through the steel pipe unloading mechanism. The steel pipe conveying chain 10 drives the steel pipe to be washed forward to enter the next mechanism.

[0046] The automatic steel pipe rotation mechanism includes a feeding flap lever 18, a cross-shaft universal coupling 63, a third bearing with a square seat 65, a third feeding crank arm block 66, a second feeding flap shaft 67, a feeding plate cylinder crank arm 68, a control feeding lifting cylinder 69, a first flap lever 19, multiple steel pipe lifting actuators, a nylon wheel motor 62, a cross-shaft universal coupling 63, a drive rotation shaft 44, and multiple steel pipe rotation actuators; a control feeding lifting cylinder is fixedly installed on the side of the flap cylinder frame 152 away from the steel pipe feeding actuator. Cylinder 69, the second feeding tilting shaft 67 is mounted in the tilting cylinder frame 152 via a third square bearing 65; the output shaft of the control feeding lifting cylinder 69 is connected to the second feeding tilting shaft 67 via the feeding plate cylinder crank arm 68, the second feeding tilting shaft 67 is connected to the feeding tilting rod 18 via the third feeding crank arm block 66, the feeding tilting rod 18 is connected to the first tilting rod 19, and the feeding tilting rod 18 and the first tilting rod 19 are connected by a pin 20, and multiple steel pipe lifting actuators are sequentially installed along the axial direction of the steel pipe. The steel pipe lifting actuators are arranged in a staggered manner, connected by a first flap rod 19, meaning the axis of the first flap rod 19 is parallel to the axis of the steel pipe. The first flap rod 19 connects the multiple steel pipe lifting actuators in series, and each steel pipe lifting actuator performs the same movement. A nylon wheel working motor 62 is also fixedly installed on the side of the flap cylinder frame 152 away from the steel pipe feeding assembly. The nylon wheel working motor 62 is installed above the control cylinder 69 for feeding and lifting. The output shaft of the nylon wheel working motor 62 is connected by a cross-shaped universal coupling. 63 is connected to the active rotating shaft 44. Each steel pipe lifting actuator is equipped with a corresponding steel pipe rotating actuator on its side. Multiple steel pipe rotating actuators are set below the steel pipe washing mechanism. The rotating wheel main shaft 47 is connected to multiple steel pipe rotating actuators in sequence. The loading lifting cylinder 69 controls the steel pipe lifting actuator to transfer the steel pipe after passing through the steel pipe transmission mechanism to the rotating drive assembly. The nylon wheel working motor 62 drives the steel pipe through the active rotating shaft 44, so that the steel pipe is rotated and washed below the steel pipe washing mechanism.

[0047] like Figure 2As shown, each steel pipe lifting actuator includes a loading flap guide sleeve 16, a first loading crank arm block 17, a pin 20, a second loading crank arm block 21, a loading support rod 22, a second bearing with a vertical seat 23, a first loading flap shaft 24, a loading lug 26, a loading double-position flap 27, and a loading flap guide tube 28. The loading flap guide sleeve 16 is fixedly installed on the ground. The loading double-position flap 27 is slidably installed on the loading flap guide sleeve 16 through the loading flap guide tube 28. The first loading flap shaft 24 is installed in the loading flap guide tube 28 through the second bearing with a vertical seat 23. The first flap pull rod 19 is connected to one end of the first loading crank arm block 17 through the pin 20. The end of the first flap pull rod 19 near the loading flap pull rod 18 is also connected through the pin 20. The other end of the first feeding crank arm block 17 is connected to the first feeding flip plate shaft 24. The lower surface of the feeding double-position flip plate 27 is equipped with a feeding ear seat 26. The first feeding flip plate shaft 24 is connected to the feeding ear seat 26 through the second feeding crank arm block 21 and the feeding support rod 22. A steel pipe slot is opened in the upper surface of the feeding double-position flip plate 27 so that the steel pipe is stably clamped on the feeding double-position flip plate 27.

[0048] The rotation of the first flap lever 19 drives the up-and-down movement of the double-position loading flap 27. Under initial conditions, the height of the double-position loading flap 27 is lower than or level with the steel pipe support arm on the upper surface of the chain tail fixed column 13.

[0049] like Figure 12 and Figure 13As shown, each steel pipe rotation actuator includes a loading flap base 25, a rotating wheel base plate 41, a second bearing with a square seat 42, a first driving sprocket 43, a rotating wheel main shaft 47, a rotating chain 45, a driven sprocket 46, a third bearing with a vertical seat 48, a rotating wheel sub-shaft 49, a first rotating nylon wheel 50, and a second rotating nylon wheel 51. The loading flap base 25 is fixed to the ground or fixedly installed in the loading flap guide sleeve 16. The rotating wheel base plate 41 is fixedly installed under the loading flap base 25. The driving rotating shaft 44 is installed in the rotating wheel base plate 41 through the second bearing with a square seat 42. The driving rotating shaft 44 is also coaxially fixed to the first driving sprocket 43 through a universal coupling joint 64. The driven sprocket 46 is installed on the loading flap base plate 41 through the bearing with a vertical seat and the rotating wheel main shaft 47. On the base 25, the driven sprocket 46 and the first driving sprocket 43 are connected by a rotating chain 45. Both the second rotating nylon wheel 51 and the first rotating nylon wheel 50 are mounted on the loading flap base 25. The second rotating nylon wheel 51 is coaxially fixed to the driven sprocket 46 via a rotating wheel spindle 47. The axial directions of the first driving sprocket 43, the driven sprocket 46, the first rotating nylon wheel 50, and the second rotating nylon wheel 51 are parallel to the axial direction of the steel pipe. The steel pipe is positioned between the first rotating nylon wheel 50 and the second rotating nylon wheel 51. The driving rotating shaft 44, the driven sprocket 46, the rotating chain 45, and the second rotating nylon wheel 51 form a rotating drive pair. The nylon wheel motor 62 drives the rotating drive pair, thereby rotating the steel pipe between the first rotating nylon wheel 50 and the second rotating nylon wheel 51. In practice, the second rotating nylon wheel 51 always maintains rotational motion.

[0050] The power controlled by the loading lifting cylinder 69 rotates through the crank arm 68 of the loading flap cylinder, driving the rotation of the second loading flap shaft 67. This, in turn, causes the third loading crank arm block 66, fixed on the second loading flap shaft 67, to rotate, transmitting power to the loading flap pull rod 18. This allows the loading flap pull rod 18 to move back and forth, causing the first flap pull rod 19 to move synchronously. Simultaneously, as the loading flap pull rod 18 moves, the first loading crank arm block 17 rotates, driving the first loading flap shaft 24 to rotate, which in turn drives the second loading crank arm block 21 to rotate. This causes the double-position loading flap 27 and the loading flap guide tube 28 to move up and down. When moving downwards, the steel pipe rolls onto the double-position loading flap 27 due to gravity. When moving upwards, the steel pipe is fixed between the nylon wheels and rotated. When moving downwards again, the steel pipe is suspended in the air and then enters the next mechanism due to gravity and rotation.

[0051] The nylon wheel motor 62 transmits power to the rotating wheel main shaft 47 via the cross-shaft universal coupling 63, causing the rotating wheel main shaft 47 to rotate. This, in turn, causes the rotating nylon wheel A51 and the driven sprocket 46 mounted on the rotating wheel main shaft 47 to rotate. The rotation of the nylon wheel A51 causes the steel pipe to rotate along with it through friction. The rotation of the driven sprocket 46 transmits power to the driving rotating shaft 44 via the driven sprocket 46 and the driving sprocket 43, causing the driving rotating shaft 44 to rotate. The rotation of the driving rotating shaft 44 then transmits power to the other side of the mechanism.

[0052] like Figure 9 , Figure 11 of (a), Figure 11 (b) and Figure 11 As shown in (c), the steel pipe flushing mechanism includes a water tank baffle 30, a right reciprocating column 32, a rear reciprocating beam 33, a front reciprocating beam 37, a worm gear reducer 34, a connecting shaft 35, a reciprocating rotary chain 36, a right drive sprocket 56, a trough 70, a left reciprocating column 71, a left driven sprocket 72, a reciprocating rotary driven shaft 73, a pre-suction pipe 11, a pre-discharge pipe 74, and a wear-resistant and corrosion-resistant water pump 75; the right reciprocating column 32 and the left reciprocating column 71 are spaced apart along the axial direction of the steel pipe, and the automatic rotation mechanism of the steel pipe is set between the right reciprocating column 32 and the left reciprocating column 71. A right drive sprocket 56 is installed in the reciprocating column 32, and a left driven sprocket 72 is installed in the left reciprocating column 71 via a reciprocating driven shaft 73. The right drive sprocket 56 and the left driven sprocket 72 are connected by a reciprocating chain 36. A worm gear reducer 34 is fixedly installed on the far right side above the rear reciprocating beam 33. The worm gear reducer 34 is connected to the right drive sprocket 56 via a connecting shaft 35. Reciprocating beams are also installed on the right reciprocating column 32 and the left reciprocating column 71. In specific implementation, the reciprocating beams are composed of a rear reciprocating beam 33 and a front reciprocating beam 37 arranged at intervals. Multiple spray gun assemblies are movably arranged at intervals in the reciprocating beams. Specifically, a reciprocating locomotive seat is fixed every few sections on the reciprocating chain. Each spray gun assembly is connected to a reciprocating rotating chain 36. A water trough 30 is installed on the ground between the right reciprocating column 32 and the left reciprocating column 71. A water pump 75 is connected to a pre-discharge pipe 74 and a pre-suction pipe 11. The pre-discharge pipe 74 is connected to multiple spray gun assemblies, and part of the pre-discharge pipe is hidden in the forward reciprocating beam. When the water pump 75 is started, the pre-suction pipe 11 draws water from the water trough 30 and then flows out from the pre-discharge pipe 74, thus rinsing the steel pipe downwards from the spray gun assembly. The wear-resistant and corrosion-resistant pump provides power for the water flow of the entire steel pipe rinsing mechanism, and the worm gear reducer provides power for the movement of the spray guns, alternating between forward and reverse rotation for a certain period of time.

[0053] like Figure 10As shown, each spray gun assembly includes a reciprocating locomotive base 39, a pre-spray gun base 40, a spray gun, and a guide rail 38. The reciprocating locomotive base 39 is installed in the reciprocating main beam, and the guide rail 38 is provided inside the reciprocating locomotive base 39. The guide rail 38 is locked in the reciprocating rotating chain 36 and is fixed relative to the reciprocating rotating chain 36. The pre-spray gun base 40 is installed on the reciprocating locomotive base 39, and the spray gun is installed in the pre-spray gun base 40. The spray gun is connected to the pre-water outlet pipe 74.

[0054] The wear-resistant and corrosion-resistant water pump 74 draws water from the water tank through the pre-suction pipe 11, and then guides the water flow to the pre-spray gun seat through the pre-discharge pipe 74, so as to rinse the water pipe to be washed. The rinsed sewage flows back to the water tank through the tank and gravity. The worm gear reducer 34 drives the left driven sprocket 56 to rotate through the reciprocating rotary drive shaft 35, which in turn drives the reciprocating rotary chain 36 to rotate, which in turn drives the multiple reciprocating locomotive seats 39 fixedly connected to the reciprocating rotary chain 36 to move on the guide rail 38.

[0055] In this invention, the steel pipe feeding mechanism controls the number of steel pipes to be washed entering the equipment by controlling the lifting and lowering of the feeding arm, and all components of the steel pipe feeding mechanism appear in pairs and are used together; the steel pipe conveying mechanism is located on the right side of the steel pipe feeding section, and conveys the steel pipes to be washed that have entered the equipment through the automatic steel pipe feeding section to the next mechanism, and the steel pipe conveying mechanism also appears in pairs and is used together; the automatic steel pipe rotating mechanism allows the steel pipes to be washed to enter the mechanism by controlling the lifting and lowering of the feeding flap guide, and the steel pipes to be washed are automatically rotated by the friction of the rotating second rotating nylon wheel 51; the steel pipe rinsing mechanism is equipped with multiple pre-spray gun seats and multiple reciprocating locomotive seats for fixing the pre-spray gun seats.
