[0002] The construction of domestic steel pipe anti-corrosion plants is partially limited by the length of the plant land. The finished product delivery area and the production line plant are not in a straight line, but in a parallel line, and the pipe delivery area of ​​the plant is close to the delivery area. The delivery method of this type of steel pipe anti-corrosion production line is mostly adopted in China: open a door along the side wall of the plant at the last process of the plant, set up a side stand that slightly extends out of the side wall by about 2-3 meters, and store the finished anti-corrosion pipes on the side stand. 3-4 steel pipes are stored, and the delivery crane needs to move to the side stand to lift the steel pipes on the side stand to the stacking area for storage, and then the crane will lift the stacked steel pipes to the shipping truck.

[0003] The disadvantages of this method are: (1) Whenever a few steel pipes are stored on the side rack, the overhead crane must be moved to the side rack area in time to lift the steel pipes on the rack to the warehouse stack. When the production rhythm is fast, the overhead crane cannot lift them in time, and the side rack is full of pipes and blocked, causing the production line to stop. (2) Since the overhead crane frequently moves to perform the task of lifting steel pipes from the rack to the stack, the maintenance cycle of the overhead crane is reduced.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] An embodiment of the present application provides a device for improving the efficiency of lateral pipe delivery to the warehouse in a steel pipe anti-corrosion plant, which can solve the problem in the related art that the number of steel pipes stored on the lateral rack is small, resulting in the need for the overhead crane to frequently switch between the stacking and shipping positions, and the overall low efficiency of lifting, shipping and delivery to the warehouse.

[0026] See also Figure 1 As shown, the embodiment of the present application provides a device for improving the efficiency of lateral pipe delivery to a steel pipe anti-corrosion plant, comprising:

[0027] A first steel pipe stand 3 is installed in a steel pipe production plant 1, and a second steel pipe stand 4 is installed in a steel pipe stacking plant 2, wherein the steel pipe production plant 1 and the steel pipe stacking plant 2 are arranged side by side, and a crane 5 for lifting steel pipes is provided in the steel pipe stacking plant 2. The crane 5 is a portal crane, and a track for the portal crane is provided on the ground of the steel pipe stacking plant 2, which is used to lift the steel pipes stored on the second steel pipe stand 4 into the steel pipe stacking plant 2 for stacking, and lift the stacked steel pipes onto a shipping vehicle.

[0028] One end of the first steel pipe rack 3 extends out of the steel pipe production plant 1 and is parallel to the second steel pipe rack 4 and tries to keep it in the same line. An end of the first steel pipe rack 3 close to the second steel pipe rack 4 is rotatably connected to an electrically controlled opening and closing connecting rod 6 that docks with the second steel pipe rack 4.

[0029] The electrically controlled opening and closing connecting rod 6 realizes the docking of the first steel pipe rack 3 and the second steel pipe rack 4 by rotation, and then the steel pipes on the first steel pipe rack 3 are rolled and stored on the second steel pipe rack 4 via the electrically controlled opening and closing connecting rod 6, thereby realizing the transfer of the steel pipes in the steel pipe production plant 1 to the steel pipe stacking plant 2, and doubling the storage quantity of the steel pipes.

[0030] The device for improving the efficiency of lateral pipe delivery to the warehouse in a steel pipe anti-corrosion plant in an embodiment of the present application is located on a second steel pipe rack 4 in a steel pipe stacking building 2, one end of the first steel pipe rack 3 extends out of the steel pipe production building 1 and is parallel to the second steel pipe rack 4, and one end of the first steel pipe rack 3 close to the second steel pipe rack 4 is rotatably connected to an electrically controlled opening and closing connecting rod 6 that docks with the second steel pipe rack 4.

[0031] When the first steel pipe rack 3 and the second steel pipe rack 4 are connected by the electrically controlled opening and closing connecting rod 6, the overhead crane 5 can wait until the second steel pipe rack 4 is filled with a large number of steel pipes before performing the task of lifting the steel pipes on the second steel pipe rack 4 to the stack, so that the overhead crane 5 has ample time to perform the task of lifting the stacked steel pipes to the shipping vehicle, and the efficiency of lifting and delivering to the warehouse is improved several times.

[0032] In some alternative embodiments: See Figure 1 As shown, an embodiment of the present application provides a device for improving the efficiency of lateral pipe delivery to the warehouse in a steel pipe anti-corrosion plant. The electrically controlled opening and closing connecting rod 6 of the device is connected to a first driving mechanism 7 that drives it to rotate around a first steel pipe stand 3. The first driving mechanism 7 is preferably but not limited to any one or more of a pneumatic cylinder, an oil cylinder, an electric cylinder, and a rack and pinion mechanism.

[0033] The first driving mechanism 7 is electrically connected to a first sensor 8 for monitoring the electrically controlled opening and closing connecting rod 6 in a docking state, and a second sensor 9 for monitoring the electrically controlled opening and closing connecting rod 6 in a disconnected state. When the first sensor 8 monitors that the electrically controlled opening and closing connecting rod 6 is in a docking state, the first sensor 8 sends a stop signal to the first driving mechanism 7, and when the second sensor 9 monitors that the electrically controlled opening and closing connecting rod 6 is in a disconnected state, the second sensor 9 sends a stop signal to the first driving mechanism 7.

[0034] In some alternative embodiments: See Figure 1 As shown, the embodiment of the present application provides a device for improving the efficiency of lateral pipe delivery to a warehouse in a steel pipe anti-corrosion plant, and the device also includes a PLC controller 10, and the PLC controller 10 is connected to a digital quantity input module 11 and a digital quantity output module 12. Among them, the first sensor 8 and the second sensor 9 are both connected to the digital quantity input module 11, and the digital quantity output module 12 is connected to the first drive mechanism 7 through a relay circuit 13.

[0035] One end of the overhead crane 5 is connected to an overhead crane limit sensor 18, and both sides of the first steel pipe stand 3 are respectively provided with a sensing iron plate 14 for monitoring the moving position of the overhead crane limit sensor 18, and a second driving mechanism 15 for driving the telescopic movement of the sensing iron plate 14. The second driving mechanism 15 is electrically connected to a third sensor 16 for monitoring the sensing iron plate 14 in an extended state, and a fourth sensor 17 for monitoring the sensing iron plate 14 in a retracted state. The third sensor 16 and the fourth sensor 17 are both connected to the digital quantity input module 11, and the second driving mechanism 15 is connected to the digital quantity output module 12 through a relay circuit 13.

[0036] The digital output module 12 is also connected to the wireless transmission module 19. A wireless alarm 20 connected to the wireless transmission module 19 by wireless signal is arranged in the cab of the overhead crane 5. When the first sensor 8 monitors that the electrically controlled opening and closing connecting rod 6 is in a docking state, the wireless transmission module 19 sends an alarm signal to the wireless alarm 20 to remind the personnel in the cab of the overhead crane 5 to prevent the overhead crane 5 from moving toward the first steel pipe stand 3 and causing a collision.

[0037] There are two sets of overhead cranes 5, which are respectively located on both sides of the second steel pipe rack 4. The two sets of overhead cranes 5 can work alternately to improve the lifting and transportation efficiency of steel pipes. The height of the first steel pipe rack 3 gradually decreases towards the second steel pipe rack 4. When the steel pipes processed in the steel pipe production plant 1 fall onto the first steel pipe rack 3, they can automatically roll freely toward the second steel pipe rack 4 and be stored on the second steel pipe rack 4.

[0038] One end of the electric opening and closing connecting rod 6 is rotatably connected to the first steel pipe stand 3 through a hinge shaft, and the electric opening and closing connecting rod 6 is turned upside down or rotated horizontally around the hinge shaft. When the electric opening and closing connecting rod 6 is disconnected from the second steel pipe stand 4 through rotation, the overhead crane 5 can move through the passage between the first steel pipe stand 3 and the second steel pipe stand 4.

[0039] One end of the first steel pipe rack 3 close to the second steel pipe rack 4 is rotatably connected to a stopper (not shown in the figure) for preventing the steel pipe from rolling toward the second steel pipe rack 4, and a drive motor (not shown in the figure) for driving the stopper to rotate up and down. When the electric-controlled opening and closing connecting rod 6 is disconnected from the second steel pipe rack 4 by rotation, the drive motor drives the stopper to rotate upward, so that the steel pipes that have been produced and processed are temporarily stored on the first steel pipe rack 3.

[0040] The drive motor is connected to the digital output module 12 via the relay circuit 13. When the second sensor 9 detects that the electrically controlled opening and closing connecting rod 6 is in the disconnected state, the PLC controller 10 controls the drive motor via the relay circuit 13 to drive the stop seat to flip upward.

[0041] How it works

[0042] When the first steel pipe rack 3 is filled with accumulated steel pipes, the "rack vertical" button is operated, and the button signal is transferred by the digital input module 11 and then acquired by the PLC controller 10. The PLC controller 10 sends a command to the digital output module 12, and the digital output module 12 sends a drive signal to the relay circuit 13. The relay circuit 13 sends a signal to the first drive mechanism 7, causing the first drive mechanism 7 to extend.

[0043] The push rod of the first driving mechanism 7 is connected to the electrically controlled opening and closing connecting rod 6 through the ear shaft. After the electrically controlled opening and closing connecting rod 6 rotates to the vertical position, it docks with the second steel pipe rack 4. After the first sensor 8 senses the electrically controlled opening and closing connecting rod 6, it sends a sensor signal to the PLC controller 10, and the PLC controller 10 sends an instruction to stop the output signal to the first driving mechanism 7, and the first driving mechanism 7 stops moving. At this time, the first steel pipe rack 3 is connected to the second steel pipe rack 4 through the electrically controlled opening and closing connecting rod 6, and the steel pipes on the first steel pipe rack 3 can be transported to the second steel pipe rack 4 for storage.

[0044] When the electrically controlled opening and closing connecting rod 6 is in the docking state, the PLC controller 10 receives the signal from the first sensor 8 and gives a driving signal to the relay circuit 13. After receiving the signal, the relay circuit 13 drives the second driving mechanism 15. The second driving mechanism 15 extends the sensing iron plate 14 and stops when it extends to the position of the third sensor 16. At this time, when the overhead crane 5 moves to the extended position of the sensing iron plate 14, the overhead crane limit sensor 18 stops moving after sensing the sensing iron plate 14 to prevent it from hitting the closed electrically controlled opening and closing connecting rod 6.

[0045] When the electric-controlled opening and closing connecting rod 6 is in the docking state, the PLC controller 10 will simultaneously send a signal to the wireless transmitting module 19 through the digital quantity input module 11, and the wireless transmitting module 19 will send a wireless signal to the wireless alarm 20 on the overhead crane 5, and the wireless alarm 20 will send a light alarm signal to the overhead crane operator to remind the operator that the electric-controlled opening and closing connecting rod 6 is in the docking state, and the overhead crane 5 is prohibited from moving toward the electric-controlled opening and closing connecting rod 6. At this time, the overhead crane 5 can perform the task of lifting the steel pipes on both sides of the electric-controlled opening and closing connecting rod 6 to the shipping vehicle.

[0046] When the second steel pipe rack 4 is just full, the following operations are performed:

[0047] When the second steel pipe rack 4 is filled with accumulated steel pipes, the button "rack flat" is operated on the control cabinet. The button signal is transferred by the digital input module 11 and then acquired by the PLC controller 10. The PLC controller 10 sends a command to the digital output module 12, and the digital output module 12 sends a drive signal to the relay circuit 13. The relay circuit 13 sends a signal to the first drive mechanism 7, causing the first drive mechanism 7 to retract.

[0048] The push rod of the first driving mechanism 7 is connected to the electrically controlled opening and closing connecting rod 6 through the ear shaft. After the electrically controlled opening and closing connecting rod 6 rotates to the horizontal position, the second sensor 9 senses the electrically controlled opening and closing connecting rod 6, and sends a sensor signal to the PLC controller 10. The PLC controller 10 sends an instruction to stop the output signal to the first driving mechanism 7, and the first driving mechanism 7 stops moving. At this time, the electrically controlled opening and closing connecting rod 6 is in the horizontal position, and the first steel pipe stand 3 and the second steel pipe stand 4 are in a disconnected state.

[0049] When the electrically controlled opening and closing connecting rod 6 is in a horizontal position, the PLC controller 10 receives the sensing signal from the second sensor 9 and sends a driving signal to the relay circuit 13. The relay circuit 13 sends a retraction signal to the second driving mechanism 15, causing the second driving mechanism 15 to retract and stop at the position of the fourth sensor 17. At this time, during the movement of the overhead crane 5 toward the first steel pipe stand 3, the distance between the sensing iron plate 14 and the overhead crane limit sensor 18 is greater than the maximum sensing distance of the stop limit, allowing the overhead crane 5 to move to the second steel pipe stand 4 to carry out the task of lifting the steel pipes on the second steel pipe stand 4.
