[0016] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0017] Embodiment 1: Figures 1 to 7 As shown, a steel pipe oiling device comprises a transverse conveying device 1, a bundled material frame 2, a lifting and handling device 3, an oiling device 4 and a draining device 5; The transverse conveying device 1 is used to convey the steel pipes to the bundling frame 2 so that the steel pipes are stacked in the bundling frame 2 to form a steel pipe bundle 6; The lifting and handling device 3 is used to grab and lift the steel pipe bundle 6 in the bundling frame 2 and transport the steel pipe bundle 6 to the oil immersion device 4 for oil immersion. The lifting and handling device 3 is also used to grab and lift the steel pipe bundle 6 in the oil immersion device 4 and transport the steel pipe bundle 6 to the draining device 5 for oil drainage.

[0018] Specifically, after the steel pipes are delivered to the transverse conveying device 1, the transverse conveying device 1 conveys the steel pipes to the bundle frame 2. As more and more steel pipes are delivered to the bundle frame 2, the steel pipes in the bundle frame 2 are stacked and placed to form a steel pipe bundle 6. Then, the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the bundle frame 2 and transports the steel pipe bundle 6 to the oil immersion device 4 for oil immersion. After the oil immersion lasts for a long enough 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 oil drainage. In this embodiment, automatic handling and lifting of steel pipes and automatic oil immersion and draining of steel pipes are realized, and no manual participation is required in the handling and lifting of steel pipes, which improves the automation level of steel pipe oil immersion processing, saves labor costs, and improves the safety of personnel, avoiding unexpected dangers during the handling and lifting of steel pipes.

[0019] More specifically, the transverse conveying device 1 can be a chain conveyor, which has a conveying chain, and the conveying chain is connected with a bump, and the bump can limit the rolling of the steel pipe carried on the conveying chain. The specific structure of the chain conveyor is a prior art well known to those skilled in the art, and will not be described in detail in this embodiment. More specifically, the steel pipe oiling equipment also includes a controller, and the transverse conveying device 1, the bundle frame 2, the lifting and handling device 3, the oiling device 4 and the draining device 5 can all be controlled by the controller, and the controller can be but not limited to a PLC.

[0020] like Figures 3-5 As shown, the bundling frame 2 may include a main frame 7, at least one lifting bracket 8, and a lifting drive mechanism 9 corresponding to the lifting bracket 8; The main frame 7 has a left blocking frame 10 and a right blocking frame 11, and the transverse conveying device 1 is used to convey the steel pipes to move between the left blocking frame 10 and the right blocking frame 11 so that the steel pipes are stacked between the left blocking frame 10 and the right blocking frame 11 to form a steel pipe bundle 6; The lifting bracket 8 is slidably connected to the main frame 7 along the up-down direction, and the lifting bracket 8 is used to hold the steel pipe transported between the left blocking frame 10 and the right blocking frame 11; 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 to a position.

[0021] like Figures 3-5 As shown, the steel pipe oil immersion equipment also includes a guide plate 12 and a counting sensor; The guide plate 12 is tiltedly disposed between the main frame 7 and the transverse conveying device 1, and the guide plate 12 is used to receive the steel pipe sent by the transverse conveying device 1 and guide the steel pipe to roll down between the left blocking frame 10 and the right blocking frame 11; The counting sensor is used to measure the quantity information of the steel pipes passing through the guide plate 12; The controller is connected to the counting sensor, and is also connected to the lifting drive mechanism 9 and is used to control the action of the lifting drive mechanism 9 according to the quantity information of the steel pipes obtained by the counting sensor to drive the lifting bracket 8 to move up and down.

[0022] Specifically, the steel pipes transported by the transverse conveying device 1 will pass through the guide plate 12 and roll down between the left blocking frame 10 and the right blocking frame 11 and be carried on the lifting bracket 8. At first, the number of steel pipes passing through the guide plate 12 and rolling down to the lifting bracket 8 is small, so the number of steel pipes passing through the guide plate 12 measured by the counting sensor is small. At this time, the controller controls the lifting drive mechanism 9 to drive the lifting bracket 8 to move upward to a higher position, thereby reducing the height difference of the steel pipes falling on the lifting bracket 8 and preventing the steel pipes from being hit. As more and more steel pipes are transported between the left blocking frame 10 and the right blocking frame 11, the number of steel pipes passing through the guide plate 12 measured by the counting sensor also increases. Therefore, the controller controls the lifting drive mechanism 9 to drive the lifting bracket 8 to gradually move downward to a lower position, thereby allowing the steel pipes to be stacked between the left blocking frame 10 and the right blocking frame 11 to form a steel pipe bundle 6.

[0023] In this embodiment, at least two lifting brackets 8 are arranged in sequence along the length direction of the steel pipes in the steel pipe bundle 6, and the lifting drive mechanism 9 corresponds to the lifting bracket 8 one by one, and the lifting drive mechanism 9 includes two lifting drive components. Among them, the lifting drive component includes a lifting screw, a lifting nut and a lifting motor, the lifting screw is rotatably connected to the main frame 7, the lifting nut is connected to the corresponding lifting bracket 8 and is connected with the lifting screw, and the lifting motor is connected to the lifting screw and is used to drive the lifting screw to rotate and then 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 to control the rotation of the lifting motor in the lifting drive mechanism 9, and the lifting motor can be a reduction motor.

[0024] In this embodiment, a first pad 13 for contacting the steel pipe is connected to the right end face of the left blocking frame 10, and the right end face of the first pad 13 is inclined from bottom to top to the left.

[0025] like Figure 1 , 6 As shown, the draining device 5 may include a base 15, an oil draining rack 16 and a telescopic driving component 17; One end of the oil drain rack 16 is rotatably connected to the base 15, and the lifting and handling device 3 is used to carry the steel pipe bundle 6 to the oil drain rack 16, so that the steel pipe bundle 6 can be drained on the oil drain rack 16; The telescopic driving component 17 is connected to the base 15 and the oil drain rack 16 and is used to drive the oil drain rack 16 to rotate to an inclined state, so that the steel pipe bundle 6 on the oil drain rack 16 is also in an inclined state, so that the oil inside the steel pipes in the steel pipe bundle 6 is also drained. In this embodiment, the telescopic driving component 17 can be an oil cylinder, the cylinder body of the oil cylinder is hinged on the base 15, the piston rod of the oil cylinder is hinged to the oil drain rack 16, and the oil cylinder is used to telescope to drive the oil drain rack 16 to rotate to an inclined state or to a horizontal state.

In this embodiment, two drain devices 5 are arranged in parallel, and of course, in some embodiments, multiple drain devices 5 can also be arranged.

[0027] To be more specific, a third pad 22 for contacting the steel pipe is connected to the right end face of the left upright frame 19, and the right end face of the third pad 22 is inclined from bottom to top to the left. A fourth pad 23 for contacting the steel pipe is connected to the left end face of the right upright frame 20, and the left end face of the fourth pad 23 is inclined from bottom to top to the right.

[0039] like Figure 1 , 5 As shown in 6, the steel pipe oil immersion equipment may also include a feeding and conveying device and a material receiving device 64; The loading and conveying device includes a ground rail 65, a loading and conveying vehicle 66 and a conveying assembly 67; The loading mobile vehicle 66 is used to travel on the ground rail 65; The conveying assembly 67 is installed on the loading moving vehicle 66, and the conveying assembly 67 is used to receive the steel pipe and convey the steel pipe to the transverse conveying device 1 when the loading moving vehicle 66 moves on the ground rail 65 until it is aligned with the transverse conveying device 1; The material receiving device 64 is arranged at one side of the draining device 5 , and the lifting and handling device 3 is also used to grab and lift the steel pipe bundle 6 in the draining device 5 and carry the steel pipe bundle 6 to the material receiving device 64 .

[0040] Specifically, the receiving device 64 is used to unbundle the steel pipe bundles 6 and transport the unbundled steel pipes to the equipment for the next process. The specific structure of the receiving device 64 is a prior art well known to those skilled in the art and will not be described in detail in this embodiment. More specifically, the loading mobile vehicle 66 can be an RGV trolley, and the conveying assembly 67 can be a chain conveyor or a belt conveyor or an automatic telescopic fork connected to the RGV trolley. More specifically, when the process information of the steel pipe bundle 6 is accompanied by a non-oil-immersed mark, the controller will control the lifting and handling device 3 to grab and lift the steel pipe bundle 6 in the bundling frame 2 and directly transport the steel pipe bundle 6 to the receiving device 64.

[0041] Specifically, the lifting and handling device 3 is used to lift and carry the steel pipe bundle 6 in the bundling material frame 2 to the oil immersion rack, then lift and carry the steel pipe bundle 6 on the oil immersion rack to the oil draining rack 16, and then lift and carry the steel pipe bundle 6 on the oil draining rack 16 to the material receiving device 64. In some embodiments, the lengths of the main frame 7 in the bundling material frame 2, the oil immersion rack, the oil draining rack 16 and the material receiving device 64 can all be smaller than the lengths of the steel pipes in the steel pipe bundle 6. Therefore, when the steel pipe bundle 6 is in any one of the bundling material frame 2, the oil immersion rack, the oil draining rack 16 and the material receiving device 64, both ends of the steel pipe bundle 6 are suspended and protruding. Therefore, the left arm 60 and the right arm 61 in one of the arm mechanisms can grab and hold the front end of the steel pipe bundle 6, and the left arm 60 and the right arm 61 in the other arm mechanism can grab and hold the rear end of the steel pipe bundle 6. Of course, in other embodiments, the main frame 7, the oil immersion rack, the oil draining rack 16 and the material receiving device 64 may be respectively provided with an activity space for the left hanging arm 60 and the right hanging arm 61 to extend downward, and the left hanging arm 60 and the right hanging arm 61 can rotate in the activity space so that the left cross arm portion 62 and the right cross arm portion 63 can be rotated to the bottom of the steel pipe bundle 6.

[0042] More specifically, the controller can control the movement of the transverse transfer vehicle 56 , control the movement of the lifting mechanism, and control the extension and retraction of the left cylinder, the right cylinder, the opening and closing cylinder 31 , and the telescopic driving component 17 .

[0043] Embodiment 2: A working method of the steel pipe oil immersion equipment as described in Embodiment 1, the method comprising the following steps: S1: the loading mobile vehicle 66 moves on the ground rail 65 until it is aligned with the transverse conveying device 1, and then the conveying assembly 67 conveys the received steel pipe to the transverse conveying device 1; S2: the transverse conveying device 1 conveys the steel pipes to the bundling frame 2 so that the steel pipes are stacked in the bundling frame 2 to form a steel pipe bundle 6; S3: the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the bundling frame 2 and carries the steel pipe bundle 6 to the oil immersion device 4 for oil immersion; S4: the lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the oil immersion device 4 and carries the steel pipe bundle 6 to the draining device 5 to drain the oil; S5: The lifting and handling device 3 grabs and lifts the steel pipe bundle 6 in the draining device 5 and carries the steel pipe bundle 6 to the material receiving device 64 .

[0044] In summary, after the steel pipes are delivered to the transverse conveying device 1, they are transported by the transverse conveying device 1 to the bundled material frame 2. As more and more steel pipes are delivered to the bundled material frame 2, the steel pipes in the bundled material frame 2 are stacked and placed to form a steel pipe bundle 6. Then, 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. After the oil immersion lasts for a long enough 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 oil drainage. In this embodiment, automatic handling and lifting of steel pipes and automatic oil immersion and draining of steel pipes are realized, and there is no need for manual participation in the handling and lifting of steel pipes, which improves the degree of automation of steel pipe oil immersion processing, saves labor costs, and improves the safety of personnel, avoiding unexpected dangers when handling and lifting steel pipes.
