Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a loading rack in an automatic processing line for steel pipes. Background Art

[0002] Steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, it is divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, it is divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) types, and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.

[0003] After searching, the Chinese patent application No. 201921830481.3 discloses an automatic feeding mechanism for steel pipes. The patent relates to a feeding device, specifically an automatic feeding mechanism for steel pipes. It is characterized in that it includes a bottom plate, a bracket on the bottom plate, and a conveying roller on the top of the bracket. There is a support plate on the bottom plate, and a feeding plate and a storage plate are arranged on the top of the support plate. The feeding plate and the storage plate are arranged in an inclined manner. The side with a low height of the feeding plate faces the conveying roller, and the height of the side with a low height of the feeding plate is higher than the height of the conveying roller. The side with a high height of the feeding plate is located above the side with a low height of the storage plate, and a baffle plate is connected between the two. There is a driving cylinder on the support plate below the storage plate, the piston rod of the driving cylinder faces upward, and there is a top block at the outer end of the piston rod of the driving cylinder. There is a controller on the support plate, and the pressure sensor and the driving cylinder are connected to the controller through wires. The use of this feeding mechanism consumes less manpower, has a high degree of automation, and has high work efficiency.

[0004] Although the above patent consumes less manpower, has a higher degree of automation and higher work efficiency, in actual use, since the patent controls the piston rod of the driving cylinder to extend through a controller to achieve feeding, if there are some continuous steel pipes when the piston rod is extended, the piston rod will be recovered at this time, and the steel pipes at the connection of the feeding plate cannot be recovered together, so that the automatic feeding mechanism directly transmits two or more steel pipes, which makes it easy for the steel pipes to accumulate on the processing line, affecting the subsequent processing. In addition, the outer diameter of the conveying roller of the patent gradually increases from the middle to the two ends. Although it has a certain effect of preventing the steel pipe from jumping out, the feeding plate is inclined, and there is a certain height difference between the feeding plate and the conveying roller, so that during the transmission process, the acceleration of the steel pipe continues to increase under the action of inertia, so that its falling speed continues to increase, which makes it difficult for the steel pipe to fall smoothly and accurately into the conveying roller, which is easy to cause safety hazards.

[0005] Therefore, it is necessary to modify the automatic feeding mechanism for steel pipes in the above-mentioned patent to effectively prevent the possibility of transmitting two or more steel pipes during the transmission process, which may easily affect the subsequent accumulation of steel pipes on the processing line, thereby affecting the subsequent processing thereof, and the steel pipes may easily fly out of the processing line during the transmission process, which may easily cause safety hazards.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a loading rack in a steel pipe automatic processing line, including a transmission rack 1, a limiting opening 2 is opened at the top of the transmission rack 1, a rotating shaft 3 is fixedly connected to one side of the transmission rack 1, and an arc strip 4 is rotatably connected to the surface of the rotating shaft 3, and a first L-shaped strip 5 and a second L-shaped strip 6 are fixedly connected to the top and bottom of the arc strip 4 respectively, and the length of the first L-shaped strip 5 is greater than the length of the second L-shaped strip 6, and a limiting column 7 is fixedly connected to the surface of the first L-shaped strip 5 and the second L-shaped strip 6, and the limiting column 7 is located at the limiting opening 2 and used in conjunction with it, a plurality of steel pipe bodies 8 are arranged on the surface of the transmission rack 1, and the plurality of steel pipe bodies 8 are evenly arranged, a cam 9 is provided at the bottom of the arc strip 4, and the surface of the cam 9 is in contact with the second L-shaped strip 6, a servo motor 10 is fixedly connected to the center of the cam 9, and the servo motor 10 is located below the transmission rack 1, and a conveyor 11 is connected to the bottom of the transmission rack 1, and baffles 12 are fixedly connected to the top of the conveyor 11 on all sides.

[0023] refer to Figure 1 and Figure 2 A discharge port 13 is provided on one side of the baffle 12 , and an electric push rod 14 is provided on one side of the conveyor 11 . A push block 15 is fixedly connected to the output end of the electric push rod 14 , and the push block 15 is used in conjunction with the discharge port 13 .

[0024] As a technical optimization solution of the utility model, by setting the discharge port 13, the electric push rod 14 and the push block 15, the steel pipe body 8 can be transferred to the designated position for feeding, thereby improving the automation of the device.

[0025] refer to Figure 1 and Figure 2 A support frame 16 is fixedly connected to the top of the conveyor 11, and the support frame 16 is located on a side close to the discharge port 13. A movable plate 17 is hinged on the top of the support frame 16. A contact sensor 18 is fixedly connected to the surface of the support frame 16, and the contact sensor 18 is used in conjunction with the movable plate 17 and the electric push rod 14 respectively.

[0026] As a technical optimization scheme of the utility model, through the setting of the support frame 16, the movable plate 17 and the contact sensor 18, when the steel pipe body 8 is transmitted to the movable plate 17, the movable plate 17 is driven to trigger the contact sensor 18, so that it can automatically start the electric push rod 14 to push the steel pipe body 8 to perform the loading operation.

[0027] refer to Figure 1 and Figure 3 The transmission frame 1 is inclined, and the cross-sectional area of ​​the restriction opening 2 is smaller than the cross-sectional area of ​​the steel pipe body 8 .

[0028] As a technical optimization solution of the utility model, the inclined setting of the transmission frame 1 can make the steel pipe main body 8 roll down along the transmission frame 1 in sequence. The setting of the cross-sectional area of ​​the limiting opening 2 being smaller than the cross-sectional area of ​​the steel pipe main body 8 can avoid the problem of the steel pipe main body 8 falling outward through the limiting opening 2.

[0029] refer to Figure 3 The spacing and height difference between the upper and lower limiting columns 7 are slightly larger than the diameter of the steel pipe body 8.

[0030] As a technical optimization solution of the utility model, by setting the spacing and height difference between the upper and lower limiting columns 7 to be slightly larger than the diameter of the steel pipe body 8, it can be ensured that when the two limiting columns 7 move alternately, one steel pipe body 8 can pass stably.

[0031] refer to Figure 1 , the height of the baffle 12 is greater than the diameter of the steel pipe body 8.

[0032] As a technical optimization solution of the present invention, by setting the height of the baffle 12 to be greater than the diameter of the steel pipe body 8, the running track of the steel pipe body 8 can be effectively blocked to ensure that it cannot jump out of the conveyor 11.

[0033] The working principle and use process of the utility model are as follows: when the staff uses the loading rack in the automatic processing line of the steel pipe, the device is first installed to a suitable position, and a plurality of steel pipe bodies 8 are placed on the transmission rack 1 (the steel pipe body 8 located at the bottom is called the quasi-steel pipe body 8, and the upper steel pipe body 8 next to the quasi-steel pipe body 8 is called the secondary falling steel pipe body 8), the discharge port 13 is connected with the feed port of other processing equipment, and then the servo motor 10 is started to drive the cam 9 to rotate. When the protruding part of the cam 9 rotates to the bottom, the weight of the arc strip 4, the first L-shaped strip 5 and the second L-shaped strip 6 is used to fall naturally, so that the limiting column 7 on the first L-shaped strip 5 can block the quasi-falling steel pipe body 8. Then, when the protruding part of the cam 9 rotates upward, it can resist the second L-shaped strip 6 and rotate with the rotating shaft 3 as the center, so that the limiting column 7 on the second L-shaped strip 6 can be inserted between the quasi-falling steel pipe body 8 and the secondary falling steel pipe body 8, so that it can block the secondary falling steel pipe body 8, and the quasi-falling steel pipe body 8 can fall along the transmission frame 1 to the conveyor 11 for transmission, and so on and so forth, to complete continuous feeding, thereby ensuring that the steel pipe body 8 can be stably loaded in sequence. When the steel pipe body 8 on the conveyor 11 is transmitted to the movable plate 17, the movable plate 17 is driven to trigger the contact sensor 18, so that it can automatically start the electric push rod 14 to push the steel pipe body 8 for loading operation.
