Description

Technical Field

[0001] The present invention relates to the technical field of steel arch frames, and more specifically, the present invention relates to an automatic feeding system for steel arch frames. Background Art

[0002] A steel arch frame is a steel structure that supports the bottom wall of a tunnel during the tunnel construction process. A steel arch frame is generally spliced by multiple sections of I-beams or H-beams, and includes a steel arch frame main body with an arc-shaped structure made of I-beams and steel end plates welded to both ends of the steel arch frame main body. During use, adjacent steel arch frames are flatly abutted against each other through the steel end plates, and then the steel end plates are fixed together by bolts or welding to achieve butt joint.

[0003] During the working process of the existing automatic feeding device for steel arch frames, the robotic arm drives the steel end plate to move, so as to place the steel end plate at both ends of the steel arch frame main body to be welded. However, during the movement of the robotic arm, due to the high weight of the steel end plate, the steel end plate will shake and tilt. Welding the tilted steel end plate to the steel arch frame main body will cause the steel arch frame to be unusable and requires reprocessing. Therefore, how to design an automatic feeding system for steel arch frames that can keep the steel end plate vertical and prevent it from tilting during the feeding process has become a problem to be solved by us. Summary of the Invention

[0006] By adopting the above technical solution, when loading the steel arch, the robotic arm drives the adsorption plate to move. The image recognition device on the adsorption plate drives the adsorption plate to adsorb steel end plates of different specifications according to the specifications of the steel arch. When the steel end plate is adsorbed onto the adsorption plate, it will squeeze the threaded slide rod, and the threaded slide rod will drive the first transmission gear to rotate through the thread. The first transmission gear will engage with the movable rack to drive the movable plate to move, and the movable plate will drive the movable extrusion plate to move. The movable extrusion plate will squeeze and fix the steel end plate, preventing the steel end plate from shaking and tilting during the movement of the robotic arm, and solving the problem that the welded steel arch cannot be used and needs to be reprocessed due to the tilt of the steel end plate during the movement.

[0007] In a preferred embodiment, the number of the movable extrusion plates is set to two, and the two movable extrusion plates are symmetrically arranged with respect to the vertical center line of the adsorption plate.

[0008] By adopting the above technical solution, the two symmetrically arranged movable extrusion plates can squeeze and fix the steel end plate from both sides during the movement, thus maintaining the vertical state of the steel end plate and preventing the steel end plate from tilting.

[0009] In a preferred embodiment, a limiting groove is formed on one side of the adsorption plate, a movable slider is fixedly connected to one side of the movable rack, and the movable slider is slidably connected inside the limiting groove.

[0011] In a preferred embodiment, an air extraction pipe is communicated and arranged on one side of the adsorption plate, a transmission rotating rod is rotatably connected inside the air extraction pipe, and a rotating fan blade is fixedly connected to one end of the transmission rotating rod.

[0012] By adopting the above technical solution, when welding the steel end plate and the steel arch, the staff can inhale the harmful gases generated during welding into the air extraction pipe through the rotation of the rotating fan blade, thus preventing the staff from inhaling these harmful gases and effectively protecting the health of the staff.

[0013] In a preferred embodiment, one end of the transmission rotating rod is rotatably connected to a rotating motor, a motor switch is fixedly connected to one side of the rotating motor, and a filter cotton block is fixedly connected to the inner wall of the air extraction pipe.

[0014] By adopting the above technical solution, when welding the steel end plate, the staff can drive the transmission rotating rod to rotate through the rotating motor, the transmission rotating rod will drive the rotating fan blade to rotate, and the rotating fan blade will suck the harmful gases generated during welding into the suction pipe, and the harmful gases entering the suction pipe will be purified and filtered by the alkaline liquid in the filter cotton block.

[0015] In a preferred embodiment, the filter cotton block is arranged on one side of the rotating fan blade, the outer wall of the movable plate is fixedly connected with a movable frame, one side of the movable frame is fixedly connected with a corresponding type extrusion column, and the corresponding type extrusion column is arranged on one side of the motor switch.

[0016] By adopting the above technical solution, when adsorbing and fixing the steel end plate, the movable plate will drive the movable frame to move, the movable frame will drive the corresponding type extrusion column to move, and the corresponding type extrusion column will squeeze the motor switch, so as to automatically turn on the rotating motor to suck the harmful gases.

[0017] In a preferred embodiment, the outer wall of the robotic arm is rotatably connected with a movable bearing, the outer wall of the movable bearing is communicated with an oil drain pipe, and one end of the oil drain pipe is communicated with an oil storage tank.

[0018] By adopting the above technical solution, after the robotic arm operates for a long time, the staff needs to replenish lubricating oil for the bearing. If the staff forgets to replenish the lubricating oil, the friction between the robotic arm and the bearing will increase, thereby increasing the wear speed of the robotic arm and reducing the service life of the robotic arm. Therefore, the staff needs to regularly drain the lubricating oil in the oil storage tank into the bearing through the oil drain pipe to replenish the lubricating oil for the robotic arm.

[0019] In a preferred embodiment, the inner wall of the oil storage tank is slidably connected with a piston push plate, and one side of the piston push plate is fixedly connected with a piston push column.

[0020] By adopting the above technical solution, the staff can move the piston push plate through the piston push column, and the piston push plate will squeeze the oil storage tank, so as to drain the lubricating oil in the oil storage tank into the movable bearing through the oil drain pipe to lubricate the movable bearing.

[0021] In a preferred embodiment, one side of the piston push column is fixedly connected with a movable toothed ring, and the inner wall of the movable toothed ring is meshed with a second transmission gear, and the second transmission gear is fixedly connected to the outer wall of the robotic arm.

[0022] By adopting the above technical solution, when the robotic arm rotates, the robotic arm will drive the second transmission gear to rotate. The second transmission gear will engage with the movable toothed ring, and the movable toothed ring will drive the piston push rod to move. The piston push rod will drive the piston push plate to extrude the lubricating oil in the oil storage tank, so that the robotic arm automatically replenishes lubricating oil for the bearing during the rotation process.

[0023] In a preferred embodiment, an oil inlet pipe is communicated and provided on one side of the oil storage tank, and a one-way valve is provided on the outer wall of the oil inlet pipe.

[0024] By adopting the above technical solution, when the robotic arm rotates clockwise, the piston push plate will move towards the piston push rod, and the oil storage tank will replenish new lubricating oil through the oil inlet pipe. When the robotic arm rotates counterclockwise, when the piston push plate moves towards the drain pipe, since the one-way valve is provided on the oil inlet pipe, the oil in the oil storage tank cannot flow into the oil inlet pipe, and all the lubricating oil in the oil storage tank will be discharged through the drain pipe to lubricate the bearing. In this way, not only can the bearing be lubricated, but also new lubricating oil can be automatically replenished for the oil storage tank.

[0025] Technical effects and advantages of the present invention:

[0026] 1. In the present invention, by providing a threaded sleeve and a movable pressing plate, when the steel end plate is adsorbed onto the adsorption plate, the threaded slide rod will be extruded by the steel end plate. The threaded slide rod will drive the first transmission gear to rotate through the thread, and the first transmission gear will engage with the movable rack to drive the movable plate to move. The movable plate will drive the movable pressing plate to press and fix the steel end plate, solving the problem that the steel end plate tilts during the movement, resulting in the unusability of the welded steel arch and the need for reprocessing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Refer to the attached drawings of the specification Figure 1-10, An automatic feeding system for a steel arch support according to an embodiment of the present invention includes a transport rack 1.

A movable pressing plate 13 is fixedly connected to one side of the movable plate 12 after movement. The number of the movable pressing plates 13 is set to two. The two movable pressing plates 13 are symmetrically arranged with respect to the vertical center line of the adsorption plate 4. The two symmetrically arranged movable pressing plates 13 can squeeze and fix the steel end plate from both sides during movement, so as to keep the steel end plate in a vertical state and prevent the steel end plate from tilting. A limiting groove 14 for allowing a movable slider 15 to move is formed in one side of the adsorption plate 4. As Figure 4 shown, a movable slider 15 for cooperating with the limiting groove 14 to limit the movement of the movable rack 11 is fixedly connected to one side of the movable rack 11. The movable slider 15 is slidably connected to the inside of the limiting groove 14.

[0041] It should be noted that when loading the steel arch frame, the robotic arm 3 drives the suction plate 4 to move. The image recognition device 5 on the suction plate 4 drives the suction plate to adsorb steel end plates of different specifications according to the specifications of the steel arch frame. After the steel end plate is sucked onto the suction plate 4, it will squeeze the threaded slide rod 6, and the threaded slide rod 6 will move. The threaded slide rod 6 will cause the threaded rotating sleeve 7 to rotate through the thread, and the threaded rotating sleeve 7 will drive the first transmission gear 8 to rotate. The first transmission gear 8 will engage with the movable rack 11, and the movable rack 11 will drive the movable plate 12 to move. The movable plate 12 will drive the movable pressing plate 13 to move, and the movable pressing plate 13 will press and fix the steel end plate, preventing the steel end plate from shaking and tilting during the movement of the robotic arm 3, solving the problem that the welded steel arch frame cannot be used and needs to be reprocessed due to the tilt of the steel end plate during movement. During the movement of the movable rack 11, it will drive the movable slider 15 to move, and the movable slider 15 will move within the limit groove 14. The movable slider 15 will cooperate with the limit groove 14 to limit the movement of the movable rack 11, preventing the movable rack 11 from shaking and shifting during movement.

[0042] Further, as Figure 7 shown, an air extraction pipe 16 for fixing the filter cotton block 21 is communicated and provided on one side of the suction plate 4. A transmission rotating rod 17 for driving the rotating fan blade 18 to rotate is rotatably connected inside the air extraction pipe 16. One end of the transmission rotating rod 17 is fixedly connected with a rotating fan blade 18 for generating suction after rotation to suck harmful gases into the air extraction pipe 16. One end of the transmission rotating rod 17 is rotatably connected with a rotating motor 19 for driving the transmission rotating rod 17 to rotate. The rotating motor 19 is an HG-JR25K1 series servo rotating motor device. One side of the rotating motor 19 is fixedly connected with a motor switch 20 for controlling the rotation of the rotating motor 19. As Figure 7 shown, a filter cotton block 21 for purifying and filtering harmful gases is fixedly connected to the inner wall of the air extraction pipe 16. The filter cotton block 21 is arranged on one side of the rotating fan blade 18. An activity frame 22 for driving the corresponding type extrusion column 23 to move is fixedly connected to the outer wall of the movable plate 12. A corresponding type extrusion column 23 for pressing the motor switch 20 after movement is fixedly connected to one side of the activity frame 22. The corresponding type extrusion column 23 is arranged on one side of the motor switch 20.

[0043] It should be noted that after the steel end plate is adsorbed and fixed, the movable plate 12 will drive the movable frame 22 to move. The movable frame 22 will drive the corresponding extrusion column 23 to move. The corresponding extrusion column 23 will squeeze the motor switch 20, thereby turning on the rotating motor 19. The rotating motor 19 will drive the transmission rotating rod 17 to rotate. The transmission rotating rod 17 will drive the rotating fan blade 18 to rotate. The rotating fan blade 18 will generate suction to suck the harmful gases generated during the welding of the steel arch into the suction pipe 16. The harmful gases entering the suction pipe 16 will be filtered by the filter cotton block 21. In this way, the nitrogen oxides in the harmful gases will be filtered by the alkaline liquid in the filter cotton block 21, thus preventing the harmful gases generated during welding from filling the workshop and being inhaled by the staff, which may affect their physical health.

[0044] Furthermore, as Figure 9 shown, a movable bearing 24 is rotatably connected to the outer wall of the robotic arm 3. An oil discharge pipe 25 for discharging the lubricating oil in the oil storage tank 26 into the movable bearing 24 is communicated with the outer wall of the movable bearing 24. One end of the oil discharge pipe 25 is communicated with an oil storage tank 26 for storing lubricating oil. A piston push plate 27 for squeezing the lubricating oil in the oil storage tank 26 after movement is slidably connected to the inner wall of the oil storage tank 26. A piston push column 28 for driving the piston push plate 27 to move is fixedly connected to one side of the piston push plate 27. An active gear ring 29 for driving the piston push column 28 to move is fixedly connected to one side of the piston push column 28. As Figure 9 shown, a second transmission gear 30 for meshing with the active gear ring after rotation is engaged with the inner wall of the active gear ring 29. The second transmission gear 30 is fixedly connected to the outer wall of the robotic arm 3. An oil inlet pipe 31 for connecting an external lubricating oil supply mechanism to replenish new lubricating oil to the oil storage tank 26 is communicated with one side of the oil storage tank 26. A check valve 32 for preventing the lubricating oil in the oil storage tank 26 from flowing into the oil inlet pipe 31 is provided on the outer wall of the oil inlet pipe 31.

[0045] It should be noted that during the long-term operation of the robotic arm 3, the staff needs to replenish lubricating oil for the bearing. If the staff forgets to replenish the lubricating oil, the friction between the robotic arm 3 and the bearing will increase, thereby increasing the wear rate of the robotic arm 3 and reducing the service life of the robotic arm 3. When the robotic arm 3 rotates, the robotic arm 3 will drive the second transmission gear 30 to rotate. The second transmission gear 30 will engage with the movable gear ring 29, and the movable gear ring 29 will drive the piston push rod 28 to move. The piston push rod 28 will drive the piston push plate 27 to move. When the robotic arm 3 rotates clockwise, the piston push plate 27 will move towards the piston push rod 28, and the fuel tank 26 will replenish new lubricating oil through the oil inlet pipe 31. When the robotic arm 3 rotates counterclockwise, when the piston push plate 27 moves towards the oil drain pipe 25, since the oil inlet pipe 31 is provided with a one-way valve, the oil in the fuel tank 26 cannot flow into the oil inlet pipe 31. All the lubricating oil in the fuel tank 26 will be discharged through the oil drain pipe 25 to lubricate the bearing. This can not only automatically lubricate the movable bearing 24, but also automatically replenish new lubricating oil for the fuel tank 26.

[0046] Working principle: When loading the steel arch, the robotic arm 3 drives the suction plate 4 to move. The image recognition device 5 on the suction plate 4 drives the suction plate to suck steel end plates of different specifications according to the specifications of the steel arch. After the steel end plate is sucked onto the suction plate 4, it will squeeze the threaded slide bar 6, and the threaded slide bar 6 will move. The threaded slide bar 6 will cause the threaded rotating sleeve 7 to rotate through the thread, and the threaded rotating sleeve 7 will drive the first transmission gear 8 to rotate. The first transmission gear 8 will engage with the movable rack 11, and the movable rack 11 will drive the movable plate 12 to move. The movable plate 12 will drive the movable extrusion plate 13 to move, and the movable extrusion plate 13 will squeeze and fix the steel end plate, preventing the steel end plate from shaking and tilting during the movement of the robotic arm 3, solving the problem that the welded steel arch cannot be used and needs to be reprocessed due to the tilt of the steel end plate during movement. During the movement of the movable rack 11, it will drive the movable slider 15 to move, and the movable slider 15 will move within the limit groove 14. The movable slider 15 will cooperate with the limit groove 14 to limit the movement of the movable rack 11, preventing the movable rack 11 from shaking and shifting during movement; After the steel end plate is adsorbed and fixed, the movable plate 12 will drive the movable frame 22 to move, and the movable frame 22 will drive the corresponding type extrusion column 23 to move. The corresponding type extrusion column 23 will squeeze the motor switch 20, thereby turning on the rotary motor 19. The rotary motor 19 will drive the transmission rotating rod 17 to rotate, and the transmission rotating rod 17 will drive the rotary fan blade 18 to rotate. The rotary fan blade 18 will generate suction to suck the harmful gases generated during the welding of the steel arch into the suction pipe 16. The harmful gases entering the suction pipe 16 will be filtered by the filter cotton block 21. In this way, the nitrogen oxides in the harmful gases will be filtered by the alkaline liquid in the filter cotton block 21, thus preventing the harmful gases generated during welding from filling the workshop and being inhaled by the staff, which affects their physical health;After the robotic arm 3 operates for a long time, the staff needs to replenish lubricating oil for the bearing. If the staff forgets to replenish the lubricating oil, the friction between the robotic arm 3 and the bearing will increase, thereby increasing the wear rate of the robotic arm 3 and reducing the service life of the robotic arm 3. When the robotic arm 3 rotates, the robotic arm 3 will drive the second transmission gear 30 to rotate. The second transmission gear 30 will engage with the movable gear ring 29, and the movable gear ring 29 will drive the piston push rod 28 to move. The piston push rod 28 will drive the piston push plate 27 to move. When the robotic arm 3 rotates clockwise, the piston push plate 27 will move towards the piston push rod 28, and the oil storage tank 26 will replenish new lubricating oil through the oil inlet pipe 31. When the robotic arm 3 rotates counterclockwise, when the piston push plate 27 moves towards the oil discharge pipe 25, since the oil inlet pipe 31 is provided with a one-way valve, the oil in the oil storage tank 26 cannot flow into the oil inlet pipe 31. All the lubricating oil in the oil storage tank 26 will be discharged through the oil discharge pipe 25 to lubricate the bearing. This can not only automatically lubricate the movable bearing 24, but also automatically replenish new lubricating oil for the oil storage tank 26.;
