Detailed implementation manners

[0070] In order to make the content of the present invention easier to be clearly understood, the following further details the present invention according to specific embodiments and in combination with the accompanying drawings.

[0071] Embodiment 1: As Figures 1 to 7 shown, a steel pipe oil immersion device includes a transverse conveying device 1, a bundling material box 2, a lifting and handling device 3, an oil immersion device 4 and a drainage device 5;

[0072] The transverse conveying device 1 is used to convey steel pipes and move them into the bundling material box 2 so that the steel pipes are stacked in the bundling material box 2 to form a steel pipe bundle 6;

[0073] The lifting and handling device 3 is used to grasp and lift the steel pipe bundle 6 in the bundling material box 2 and transport the steel pipe bundle 6 to the oil immersion device 4 for oil immersion, and the lifting and handling device 3 is also used to grasp and lift the steel pipe bundle 6 in the oil immersion device 4 and transport the steel pipe bundle 6 to the drainage device 5 for oil drainage.

[0074] Specifically, after the steel pipes are sent to the transverse conveying device 1, the transverse conveying device 1 conveys the steel pipes to move into the bundling frame 2. As more and more steel pipes are conveyed into the bundling frame 2, the steel pipes in the bundling frame 2 are stacked to form a steel pipe bundle 6. Then, the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the bundling frame 2 and transports the steel pipe bundle 6 to the oil immersion device 4 for oil immersion. After oil immersion for a sufficient length of time, the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the oil immersion device 4 and transports the steel pipe bundle 6 to the draining device 5 for draining. In this embodiment, automatic handling and hoisting of steel pipes are realized, and automatic oil immersion and draining of steel pipes are achieved. There is no need for manual participation in handling and hoisting steel pipes, which improves the automation degree of steel pipe oil immersion treatment, saves labor costs, and also improves the safety of personnel, avoiding accidental dangers during handling and hoisting of steel pipes.

[0075] More specifically, the transverse conveying device 1 can be a chain conveyor. The chain conveyor has a conveying chain, and a convex block is connected to the conveying chain. The convex block can limit the rolling of the steel pipes carried on the conveying chain. The specific structure of the chain conveyor is well-known prior art to those skilled in the art and will not be specifically described in this embodiment. Further specifically, the steel pipe oil immersion equipment further includes a controller. The transverse conveying device 1, the bundling frame 2, the lifting and handling device 3, the oil immersion device 4, and the draining device 5 can all be controlled by the controller to act. The controller can be, but is not limited to, a PLC.

[0076] As Figures 3 to 5 shown, the bundling frame 2 can include a main body frame 7, at least one lifting bracket 8, and a lifting drive mechanism 9 corresponding to the lifting bracket 8;

[0077] The main body frame 7 has a left blocking frame body 10 and a right blocking frame body 11. The transverse conveying device 1 is used to convey the steel pipes to move between the left blocking frame body 10 and the right blocking frame body 11 so that the steel pipes are stacked between the left blocking frame body 10 and the right blocking frame body 11 to form a steel pipe bundle 6;

[0078] The lifting bracket 8 is slidably connected to the main body frame 7 in the up and down direction. The lifting bracket 8 is used to support the steel pipes conveyed between the left blocking frame body 10 and the right blocking frame body 11;

[0079] The lifting drive mechanism 9 is connected to the corresponding lifting bracket 8 and is used to drive the corresponding lifting bracket 8 to move up and down in place.

[0080] As Figures 3 to 5 shown, the steel pipe oil immersion equipment further includes a guiding plate 12 and a counting sensor;

[0081] The guiding plate 12 is inclined and arranged between the main body frame 7 and the transverse conveying device 1. The guiding plate 12 is used for receiving the steel pipes delivered by the transverse conveying device 1 and guiding the steel pipes to roll down between the left blocking frame body 10 and the right blocking frame body 11;

[0082] The counting sensor is used for measuring the quantity information of the steel pipes passing through the guiding plate 12;

[0083] The controller is connected to the counting sensor. The controller is also connected to the lifting drive mechanism 9 and is used for controlling the lifting drive mechanism 9 to act according to the quantity information of the steel pipes obtained by the counting sensor so as to drive the lifting bracket 8 to move up and down.

[0084] Specifically, the steel pipes delivered by the transverse conveying device 1 will pass through the guiding plate 12 and roll down between the left blocking frame body 10 and the right blocking frame body 11 and be carried on the lifting bracket 8. At first, the number of steel pipes passing through the guiding plate 12 and rolling down onto the lifting bracket 8 is small. Therefore, the quantity information of the steel pipes passing through the guiding plate 12 measured by the counting sensor is small. At this time, the controller controls the lifting drive mechanism 9 to act to drive the lifting bracket 8 to move upward to a higher position, so as to reduce the falling height difference of the steel pipes falling on the lifting bracket 8 and prevent the steel pipes from being damaged. As more and more steel pipes are conveyed between the left blocking frame body 10 and the right blocking frame body 11, the number of steel pipes passing through the guiding plate 12 measured by the counting sensor is also increasing. Therefore, the controller controls the lifting drive mechanism 9 to drive the lifting bracket 8 to gradually move downward to a lower position, so that the steel pipes can be stacked between the left blocking frame body 10 and the right blocking frame body 11 to form a steel pipe bundle 6.

[0085] In this embodiment, at least two lifting brackets 8 are sequentially arranged at intervals along the length direction of the steel pipes in the steel pipe bundle 6. The lifting drive mechanism 9 corresponds to the lifting brackets 8 one by one. The lifting drive mechanism 9 includes two lifting drive components. Among them, the lifting drive component includes a lifting lead screw, a lifting nut and a lifting motor. The lifting lead screw is rotatably connected to the main body frame 7. The lifting nut is connected to the corresponding lifting bracket 8 and is in cooperation connection with the lifting lead screw. The lifting motor is connected to the lifting lead screw and is used for driving the lifting lead screw to rotate so as to drive the lifting nut to move up and down and then drive the lifting bracket 8 to move up and down. Among them, the controller is used for controlling the rotation action of the lifting motor in the lifting drive mechanism 9, and the lifting motor can be a reduction motor.

[0086] In this embodiment, a first backing plate 13 for contacting the steel pipe is connected to the right end face of the left blocking frame body 10. The right end face of the first backing plate 13 is inclined leftward from bottom to top. A second backing plate 14 for contacting the steel pipe is connected to the left end face of the right blocking frame body 11. The left end face of the second backing plate 14 is inclined rightward from bottom to top. This can prevent the problem that the steel pipe bundle 6 is stuck when lifting the steel pipe bundle 6 between the left blocking frame body 10 and the right blocking frame body 11.

[0087] As Figure 1 , 6 shown, the draining device 5 may include a base 15, an oil draining rack 16 and a telescopic driving member 17;

[0088] One end of the oil draining rack 16 is rotatably connected to the base 15. The lifting and handling device 3 is used to transport the steel pipe bundle 6 onto the oil draining rack 16 so that the steel pipe bundle 6 drains oil on the oil draining rack 16.

[0089] The telescopic driving member 17 is connected to the base 15 and is connected to the oil draining rack 16 and is used to drive the oil draining rack 16 to rotate to an inclined state, so that the steel pipe bundle 6 on the oil draining rack 16 is also in an inclined state, and thus the oil inside the steel pipes in the steel pipe bundle 6 is drained. In this embodiment, the telescopic driving member 17 may be an oil cylinder. The cylinder body of the oil cylinder is hinged to the base 15, and the piston rod of the oil cylinder is hinged to the oil draining rack 16. The oil cylinder is used to expand and contract to drive the oil draining rack 16 to rotate to an inclined state or to a horizontal state.

[0090] Specifically, the oil draining rack 16 includes a bottom frame body 18, a left vertical frame 19, a right vertical frame 20 and a support bracket 21. Among them, the lower ends of the left vertical frame 19 and the right vertical frame 20 are both connected to the bottom frame body 18. One end of the support bracket 21 is connected to the left vertical frame 19, and the other end of the support bracket 21 is connected to the right vertical frame 20. The lifting and handling device 3 is used to transport the steel pipe bundle 6 between the left vertical frame 19 and the right vertical frame 20 and place the steel pipe bundle 6 on the support bracket 21. In this embodiment, two draining devices 5 are arranged in parallel. Of course, in some embodiments, multiple draining devices 5 may also be provided.

[0091] Further specifically, a third backing plate 22 for contacting the steel pipe is connected to the right end face of the left vertical frame 19. The right end face of the third backing plate 22 is inclined leftward from bottom to top. A fourth backing plate 23 for contacting the steel pipe is connected to the left end face of the right vertical frame 20. The left end face of the fourth backing plate 23 is inclined rightward from bottom to top. This can prevent the problem that the steel pipe bundle 6 is stuck when lifting the steel pipe bundle 6 between the left vertical frame 19 and the right vertical frame 20.

[0092] As shown Figures 5 to 7 in FIG. 2, the oil immersion device 4 may include an oil immersion rack, an oil immersion tank 24, a water tank 25, a heating device, and an internal circulation pipeline 26;

[0093] The oil immersion rack is arranged in the oil immersion tank 24. The oil immersion tank 24 is filled with oil. The lifting and handling device 3 is used to grasp and lift the steel pipe bundle 6 in the bundled material frame 2 and transport the steel pipe bundle 6 to the oil immersion rack in the oil immersion tank 24. The lifting and handling device 3 is also used to grasp and lift the steel pipe bundle 6 on the oil immersion rack and transport the steel pipe bundle 6 to the draining device 5;

A circulation pump 27 is connected in the internal circulation pipeline 26.

[0097] Specifically, the oil immersion rack is of a U-shaped structure. The steel pipe bundle 6 on the oil immersion rack is immersed in the oil in the oil immersion tank 24. Under the pumping of the circulation pump 27, the oil in the oil immersion tank 24 can circulate through the internal circulation pipeline 26. A filter 28 and at least one first valve 29 are also connected in the internal circulation pipeline 26, and the first valve 29 can be a manual ball valve.

[0098] The oil immersion device 4 further includes a cover plate 30 and an opening and closing cylinder 31. The cover plate 30 is rotatably connected to the oil immersion tank 24. One end of the opening and closing cylinder 31 is hinged to the oil immersion tank 24, and the other end of the opening and closing cylinder 31 is hinged to the cover plate 30. The opening and closing cylinder 31 is used for telescoping to drive the cover plate 30 to rotate to open or close.

[0102] The controller is respectively connected to the oil level gauge 32 and the oil replenishing pump 35. The controller is used to control the operation of the oil replenishing pump 35 according to the oil level height information monitored by the oil level gauge 32, so as to pump the oil in the oil replenishing container 34 into the internal circulation pipeline 26. Specifically, when the oil level height information monitored by the oil level gauge 32 is lower than the lower limit value, the controller controls the oil replenishing pump 35 to operate to pump the oil in the oil replenishing container 34 into the internal circulation pipeline 26, and then replenish the oil into the immersion tank 24.

[0103] The immersion device 4 may further include a water content monitor 36, a first water replenishing branch 37, and a water replenishing container 38 filled with pure water.

The controller is used to control the water replenishment valve 45 to open to replenish water into the water tank 25 according to the water level height information monitored by the water level gauge 43. Specifically, when the water level height information monitored by the water level gauge 43 in the water tank 25 is lower than the lower limit value, the controller controls the water replenishment valve 45 to open to replenish water into the water tank 25. When the water level height information monitored by the water level gauge 43 in the water tank 25 reaches the upper limit value, the controller controls the water replenishment valve 45 to close to end the water replenishment. Among them, the water source can be tap water, and the water replenishment valve 45 can be a pneumatic ball valve. In this embodiment, check valves are respectively connected in the oil replenishment branch 33, the first water replenishment branch 37 and the acid value adjustment branch 40.

[0116] The controller is respectively connected to the first thermometer 46 and the intake valve 49 and is used to control the opening and closing of the intake valve 49 according to the oil temperature information monitored by the first thermometer 46; Specifically, when the first thermometer 46 monitors that the oil temperature in the oil immersion tank 24 is lower than the threshold, the controller controls the intake valve 49 to open so that steam flows into the steam heating pipe 47 through the inlet pipeline, and then heats the water in the water tank 25, and then heats the oil in the oil immersion tank 24 through the water in the water tank 25, and then the condensed water in the steam heating pipe 47 flows into the steam condensate sump 48 through the outlet pipeline.

[0117] More specifically, a second valve 50, a third valve 51, a steam trap 52 and a check valve are connected in the outlet pipeline. The steam trap 52, the second valve 50 and the check valve are connected in series in sequence. One end of the third valve 51 is connected in parallel with one end of the steam trap 52 and then connected to the outlet end of the steam heating pipe 47.

[0118] As Figures 1 to 6 shown, the lifting and handling device 3 includes a lifting track 55, a cross - transfer vehicle 56, a lifting mechanism 57 and a grasping mechanism 58;

[0119] The grasping mechanism 58 is used to grasp and support the steel pipe bundle 6;

[0120] The lifting mechanism 57 is connected to the cross - transfer vehicle 56 and is connected to the grasping mechanism 58. The lifting mechanism 57 is used to drive the grasping mechanism 58 to move up and down, and then lift or lower the steel pipe bundle 6 grasped and supported by the grasping mechanism 58;

[0121] The cross - transfer vehicle 56 is installed on the lifting track 55 and is used to travel along the lifting track 55 and then drive the lifted steel pipe bundle 6 to move horizontally; In this embodiment, the lifting mechanism 57 can be an electric hoist connected to the cross - transfer vehicle 56, and the cross - transfer vehicle 56 and the electric hoist form a trolley - type electric hoist.

[0122] As Figures 1 to 6As shown, the grasping mechanism 58 may include a platform base 59 and at least two boom mechanisms connected to the platform base 59. The boom mechanisms include a left boom 60, a right boom 61, a left drive mechanism, and a right drive mechanism;

[0123] The hoisting mechanism 57 is connected to the traversing vehicle 56 and is connected to the platform base 59 in the grasping mechanism 58. The hoisting mechanism 57 is used to drive the platform base 59 to rise or fall;

[0124] The upper end of the left boom 60 and the upper end of the right boom 61 are respectively rotatably connected to the platform base 59. The left boom 60 is used to extend downward to the left side of the steel pipe bundle 6 when the hoisting mechanism 57 drives the platform base 59 to descend. The right boom 61 is used to extend downward to the right side of the steel pipe bundle 6 when the hoisting mechanism 57 drives the platform base 59 to descend;

[0125] The lower end of the left boom 60 is provided with a left cross-arm portion 62. The left drive mechanism is connected to the platform base 59 and is connected to the left boom 60. The left drive mechanism is used to drive the left boom 60 to rotate to the first material-supporting position so that the left cross-arm portion 62 rotates to below the steel pipe bundle 6. The left drive mechanism is also used to drive the left boom 60 to rotate to the first material-releasing position so that the left cross-arm portion 62 rotates to withdraw from below the steel pipe bundle 6;

[0126] The lower end of the right boom 61 is provided with a right cross-arm portion 63. The right drive mechanism is connected to the platform base 59 and is connected to the right boom 61. The right drive mechanism is used to drive the right boom 61 to rotate to the second material-supporting position so that the right cross-arm portion 63 rotates to below the steel pipe bundle 6. The right drive mechanism is also used to drive the right boom 61 to rotate to the second material-releasing position so that the right cross-arm portion 63 rotates to withdraw from below the steel pipe bundle 6.

[0127] Specifically, the process of the lifting and handling device 3 lifting and handling the steel pipe bundle 6 is as follows. First, the cross-carriage 56 travels along the lifting track 55 to above the steel pipe bundle 6 to be lifted. The left driving mechanism drives the left lifting arm 60 to rotate to the first discharging position, and the right driving mechanism drives the right lifting arm 61 to rotate to the second discharging position. Then the lifting mechanism 57 drives the platform seat 59 to descend so that the left lifting arm 60 extends downward to the left side of the steel pipe bundle 6 and the right lifting arm 61 extends downward to the right side of the steel pipe bundle 6. Then the left driving mechanism drives the left lifting arm 60 to rotate to the first material supporting position so that the left cross-arm part 62 rotates to below the steel pipe bundle 6, and the right driving mechanism drives the right lifting arm 61 to rotate to the second material supporting position so that the right cross-arm part 63 rotates to below the steel pipe bundle 6. At this time, the left lifting arm 60 and the right lifting arm 61 grasp the steel pipe bundle 6 and support the steel pipe bundle 6 through the left cross-arm part 62 and the right cross-arm part 63. Then the lifting mechanism 57 drives the platform seat 59 to rise, thereby driving the left lifting arm 60 and the right lifting arm 61 to rise and then lifting the steel pipe bundle 6 upward. Then the cross-carriage 56 travels along the lifting track 55 and drives the lifted steel pipe bundle 6 to move horizontally to the position where discharging is required. Then the lifting mechanism 57 drives the platform seat 59 to descend and then puts down the steel pipe bundle 6. Then the left driving mechanism drives the left lifting arm 60 to rotate to the first discharging position so that the left cross-arm part 62 rotates to withdraw from below the steel pipe bundle 6, and the right driving mechanism drives the right lifting arm 61 to rotate to the second discharging position so that the right cross-arm part 63 rotates to withdraw from below the steel pipe bundle 6. Then the lifting mechanism 57 drives the platform seat 59 to rise and then drives the left lifting arm 60 and the right lifting arm 61 to rise, thus completing the putting down of the steel pipe bundle 6.

[0128] Wherein, the left driving mechanism includes a left air cylinder and a left connecting rod. The left connecting rod is connected to the left lifting arm 60. One end of the left air cylinder is hinged on the platform seat 59, and the other end of the left air cylinder is hinged to the left connecting rod. When the left air cylinder expands and contracts, it can drive the left lifting arm 60 to rotate between the first material supporting position and the first discharging position through the left connecting rod.

[0129] Wherein, the right driving mechanism includes a right air cylinder and a right connecting rod. The right connecting rod is connected to the right lifting arm 61. One end of the right air cylinder is hinged on the platform seat 59, and the other end of the right air cylinder is hinged to the right connecting rod. When the right air cylinder expands and contracts, it can drive the right lifting arm 61 to rotate between the second material supporting position and the second discharging position through the right connecting rod.

[0130] As Figure 1 、 5 、shown in 6, the steel pipe oil immersion equipment may further include a feeding conveying device and a receiving device 64;

[0131] The feeding and conveying device includes a ground rail 65, a feeding mobile vehicle 66 and a conveying component 67;

[0132] The feeding mobile vehicle 66 is used to travel on the ground rail 65;

[0133] The conveying component 67 is installed on the feeding mobile vehicle 66. The conveying component 67 is used to receive steel pipes and convey the steel pipes to the transverse conveying device 1 when the feeding mobile vehicle 66 travels on the ground rail 65 to align with the transverse conveying device 1;

[0134] The receiving device 64 is arranged on one side of the draining device 5. The lifting and handling device 3 is further used to grasp and lift the steel pipe bundle 6 in the draining device 5 and transport the steel pipe bundle 6 to the receiving device 64.

[0135] Specifically, the receiving device 64 is used to untie the steel pipe bundle 6 and convey the unbundled steel pipes to the equipment of the next process for feeding. The specific structure of the receiving device 64 is the prior art well-known to those skilled in the art and will not be specifically described in this embodiment. Further specifically, the feeding mobile vehicle 66 can be an RGV vehicle, and the conveying component 67 can be a chain conveyor or a belt conveyor or an automatic telescopic forklift connected to the RGV vehicle. Further specifically, when the process information of the steel pipe bundle 6 is attached with a non-oil-immersed label, the controller will control the lifting and handling device 3 to grasp and lift the steel pipe bundle 6 in the bundled material frame 2 and directly transport the steel pipe bundle 6 to the receiving device 64.

[0136] Specifically, the lifting and handling device 3 is used to lift the steel pipe bundle 6 in the bundled material frame 2 and transport it to the oil immersion rack, then lift the steel pipe bundle 6 on the oil immersion rack and transport it to the oil draining rack 16, and then lift the steel pipe bundle 6 on the oil draining rack 16 and transport it to the receiving device 64. In some embodiments, the lengths of the main frame 7 in the bundled material frame 2, the oil immersion rack, the oil draining rack 16, and the receiving device 64 can all be less than the length of the steel pipes in the steel pipe bundle 6. Therefore, when the steel pipe bundle 6 is in any one of the bundled material frame 2, the oil immersion rack, the oil draining rack 16, and the receiving device 64, both ends of the steel pipe bundle 6 are suspended and protruding. Thus, the left lifting arm 60 and the right lifting arm 61 in one of the lifting arm mechanisms can grab and support the front end of the steel pipe bundle 6, and the left lifting arm 60 and the right lifting arm 61 in the other lifting arm mechanism can grab and support the rear end of the steel pipe bundle 6. Of course, in some other embodiments, the main frame 7, the oil immersion rack, the oil draining rack 16, and the receiving device 64 can respectively be provided with an activity space for the left lifting arm 60 and the right lifting arm 61 to extend downward, and the left lifting arm 60 and the right lifting arm 61 can rotate in the activity space so that the left cross-arm portion 62 and the right cross-arm portion 63 can rotate to below the steel pipe bundle 6.

[0137] More specifically, the controller can control the traveling of the crosswise moving vehicle 56, control the operation of the lifting mechanism, and control the telescoping of the left cylinder, the right cylinder, the opening and closing cylinder 31, and the telescopic driving component 17.

[0138] Embodiment 2: A working method of a steel pipe oil immersion device as described in Embodiment 1, and the steps of the method include:

[0139] S1: The loading and moving vehicle 66 travels on the ground rail 65 until it aligns with the crosswise conveying device 1, and then the conveying component 67 conveys the received steel pipes to the crosswise conveying device 1.

[0140] S2: The crosswise conveying device 1 conveys the steel pipes and moves them into the bundled material frame 2 so that the steel pipes are stacked in the bundled material frame 2 to form a steel pipe bundle 6.

[0141] S3: The lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the bundled material frame 2 and transports the steel pipe bundle 6 to the oil immersion device 4 for oil immersion.

[0142] S4: The lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the oil immersion device 4 and transports the steel pipe bundle 6 to the draining device 5 for oil draining.

[0143] S5: The lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the draining device 5 and transports the steel pipe bundle 6 to the receiving device 64.

[0144] In summary, after the steel pipes are sent to the transverse conveying device 1, the transverse conveying device 1 conveys the steel pipes and moves them into the bundling frame 2. As more and more steel pipes are conveyed into the bundling frame 2, the steel pipes in the bundling frame 2 are stacked to form a steel pipe bundle 6. Then, the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the bundling frame 2 and transports the steel pipe bundle 6 to the oil immersion device 4 for oil immersion. After oil immersion for a sufficient length of time, the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the oil immersion device 4 and transports the steel pipe bundle 6 to the draining device 5 for draining. In this embodiment, automatic handling and hoisting of steel pipes are realized, and automatic oil immersion and draining of steel pipes are also realized. There is no need for manual participation in handling and hoisting steel pipes, which improves the automation degree of steel pipe oil immersion treatment, saves labor costs, and also improves the safety of personnel, avoiding accidental dangers during handling and hoisting of steel pipes.

[0145] In the specific embodiments described above, the technical problems solved by the present invention, the technical solutions and the beneficial effects are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention.
