Description

TECHNICAL FIELD

[0001] The utility model relates to cold annealing pickling line technical field, concretely relates to a steel coil steel sleeve transfer system and cold annealing pickling line. BACKGROUND

[0002] The cold annealing pickling line is a production line for processing metal strip (especially steel strip) in the metal processing industry, which ensures the performance and quality of the metal strip in the subsequent processing and use process, and is an indispensable part of the metal processing industry. Its main functions include: removing oil stains on the surface of the steel strip by degreasing; annealing to eliminate residual stress in the steel strip processing process, improve metal organization and promote uniformity of organization; pickling to remove the scale on the surface of the metal strip, improve the surface finish and flatness of the metal strip, and reduce surface defects. Compared with traditional hot pickling, the cold annealing pickling line is usually more environmentally friendly and has lower energy consumption. When the steel strip is processed in the cold annealing pickling line, the steel coil is first unwound by an uncoiler; secondly, the straightening machine is straightened, and the abnormal part of the head and tail is cut by a shear; at the same time, the straightened strip is welded by a welding machine to form a continuous strip with connected head and tail. The welded strip enters the degreasing section for degreasing, oil removal and cleaning and rinsing. The degreased strip enters the annealing furnace after accumulating in the loop. The annealed strip enters the pickling section for pickling, cleaning and rinsing to remove the surface rust. The pickled strip passes through the equipment in the outlet section for leveling and stranding, and then enters the outlet section for slitting and coiling to obtain the finished product. In the whole process, the equipment in each section is precisely controlled and coordinated to ensure the continuous processing and high-quality completion of the strip.

[0003] The steel coil loading equipment near the uncoiler of the inlet section includes an unmanned travelling crane and a steel coil trolley, and a plurality of steel coil saddles are arranged near the uncoiler. The working process of the uncoiler is as follows: the unmanned travelling crane transports the steel coil of the strip sleeve to the steel coil saddle, then the steel coil trolley lifts the steel coil (the strip sleeve located on the steel coil saddle) and transports it to the core shaft of the uncoiler, and adjusts the position to ensure that the steel coil material is basically consistent with the center line of the expanding core shaft of the uncoiler. After the steel coil is expanded, the equipment automatically rotates the uncoiler, and the uncoiler feeds the steel coil material into the straightening machine and the shear machine. The main function of the unmanned travelling crane is to automatically lift and place the hard steel coil (with number) according to the production order and rhythm of the cold annealing pickling line on the steel coil saddle at the inlet of the cold annealing pickling line. In addition, the unmanned travelling crane also brings back the steel sleeve of the last hard steel coil to the rolling production line for recycling.

[0004] At present, the unmanned vehicle carries the steel sleeve of the steel coil to the steel coil saddle, then the unmanned vehicle returns to the above material with the next steel coil, then the steel coil trolley lifts the steel coil and moves horizontally to the coil drum of the uncoiler, after the steel coil material is expanded, the uncoiler is started, the uncoiler unwinds the steel coil and sends it into the subsequent straightening machine and shearing machine and other equipment. Then the steel sleeve is taken off from the steel sleeve of the uncoiler by the steel coil trolley, and the unmanned vehicle returns to carry the next steel coil to the steel coil saddle, and the steel sleeve on the steel coil trolley is taken away.

[0005] Since the steel coil trolley needs to wait for the unmanned vehicle to take away the steel sleeve after taking off the steel sleeve on the uncoiler, the steel sleeve cannot be taken off in time, but stays on the steel coil trolley, thereby blocking the online channel of the next planned hard state steel coil, and the cold annealing and pickling line production is forced to slow down or stop waiting. Practical new type content

[0006] The problem to be solved by the present application is that the steel coil trolley needs to wait for the unmanned vehicle to take away the steel sleeve after taking off the steel sleeve on the uncoiler, so the steel sleeve cannot be taken off in time, but stays on the steel coil trolley, thereby blocking the online channel of the next planned hard state steel coil, and the cold annealing and pickling line production is forced to slow down or stop waiting.

[0034] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figures 1-5 As shown, Embodiment 1 of this utility model provides a steel coil and steel sleeve transfer system, which is applied in a cold annealing and pickling line. The cold annealing and pickling line includes an uncoiler 10 and a steel coil trolley 11 arranged along a first direction. The steel coil and steel sleeve transfer system includes a ground rail 1, a moving base 2, a linear drive device, a support platform, and a transition platform. The ground rail 1 is arranged on one side of the uncoiler 10 along a second direction, which is perpendicular to the first direction.

[0036] The movable base 2 is slidably mounted on the ground rail 1, and the linear drive device is used to drive the movable base 2 to move along the second direction on the ground rail 1;

[0037] The transition platform and the support platform are installed on the mobile base 2. The transition platform is located between the support platform and the uncoiler 10. The end of the transition platform closer to the support platform is lower than the other end. The transition platform is used to receive the steel sleeve that is overturned by the steel coil trolley 11, and the support platform is used to receive the steel sleeve that rolls off the transition platform.

[0038] The first direction is Figure 1 The arrangement direction of the decoiler 10 and the coil car 11, i.e. Figure 1 The left-right direction in the figure. The second direction is Figure 1 The extension direction of the ground rail 1, i.e. Figure 1 The front-rear direction in the figure.

[0039] It should be noted that the working mode of the unmanned vehicle in the prior art is basically divided into two types:

[0040] The first type is that the unmanned vehicle transports the steel coil with the steel sleeve to the steel coil saddle, then the unmanned vehicle returns empty, then the coil car 11 lifts the steel coil and moves it horizontally to the reel of the decoiler 10, after the steel coil material is expanded, the decoiler 10 is started, the decoiler 10 unwinds the steel coil and sends it into the subsequent equipment such as the straightening machine and the shearing machine. Then the coil car 11 takes the steel sleeve from the steel sleeve of the decoiler 10, waits for the unmanned vehicle to return, and the unmanned vehicle transports the next steel coil to the steel coil saddle and takes away the steel sleeve on the coil car 11. Since the coil car 11 needs to wait for the unmanned vehicle to lift away the steel sleeve after taking it off the decoiler 10, the steel sleeve cannot be lifted away in time and is left on the coil car 11, thereby blocking the on-line channel of the next planned hard state steel coil, and the cold annealing and pickling line production is forced to slow down or stop waiting.

[0041] The second type is that the unmanned vehicle transports the steel coil with the steel sleeve to the steel coil saddle and waits for a period of time, the coil car 11 lifts the steel coil and moves it horizontally to the reel of the decoiler 10, after the steel coil material is expanded, the decoiler 10 is started, the decoiler 10 unwinds the steel coil and sends it into the subsequent equipment such as the straightening machine and the shearing machine. Then the coil car 11 takes the steel sleeve from the steel sleeve of the decoiler 10, and the unmanned vehicle transports the taken steel sleeve back. However, since the unmanned vehicle needs to wait for the decoiler 10 to unwind the steel coil and for the coil car 11 to take the steel sleeve from the steel sleeve of the decoiler 10, the feeding rate of the unmanned vehicle is delayed, and the utilization rate of the unmanned vehicle is low.

[0042] Different from the prior art, in the present application, after the steel coil is unwound on the uncoiler 10, the steel coil trolley 11 takes the steel sleeve from the steel sleeve on the uncoiler 10, then the linear drive device drives the moving base 2 to move on the ground rail 1 to approach the steel coil trolley 11, so that the high end of the transition platform is close to the steel coil trolley 11, then the turnover hydraulic cylinder 112 carried by the steel coil trolley 11 pushes the steel sleeve, so that the steel sleeve rolls off from the steel coil trolley 11 to the transition platform and rolls along the transition platform to the bearing platform, and then the linear drive device drives the moving base 2 to move away from the steel coil trolley 11. In this way, after the unmanned vehicle carries the steel sleeve on the steel coil saddle, the unmanned vehicle can conveniently carry the steel sleeve on the bearing platform back to the rolling production line, so that after the steel coil trolley 11 takes the steel sleeve on the uncoiler 10, the steel coil trolley 11 can immediately deliver the next steel coil to the uncoiler 10 without waiting for the unmanned vehicle to lift the steel sleeve, thereby avoiding the problem that the cold annealing and pickling line production is forced to slow down or stop for waiting due to the steel coil trolley 11 blocking the online channel of the next planned hard state steel coil, thereby improving the production efficiency of the cold annealing and pickling line. And ensure the feeding rate of the unmanned vehicle, the utilization rate of the unmanned vehicle is high.

[0043] In addition, the present steel sleeve feeding system can also avoid the problem of low production efficiency caused by the previous steel coil blocking the online channel of the next steel coil when the production plan sequence is corrected or changed.

[0044] For the convenience of description, the three steel coil saddles in Figure 1 are named as the first steel coil saddle 12, the second steel coil saddle 13 and the third steel coil saddle 14 in turn, wherein the first steel coil saddle 12 is close to the uncoiler 10, and the third steel coil saddle 14 is far away from the uncoiler 10.

[0045] For the convenience of understanding, it is assumed that the production plan needs to be processed in the order of carbon steel coil, stainless steel coil and galvanized steel coil, and the first steel coil saddle 12, the second steel coil saddle 13 and the third steel coil saddle 14 are respectively placed with carbon steel coil, stainless steel coil and galvanized steel coil. If the plan order needs to be corrected, it is assumed that the order of stainless steel coil, carbon steel coil and galvanized steel coil is needed. The carbon steel coil on the first steel coil saddle 12 is lifted by the steel coil trolley 11 and moved to the left to the set position, and then the linear drive device drives the moving base 2 to move on the ground rail 1 to approach the steel coil trolley 11, so that the high end of the transition table is close to the steel coil trolley 11, and then the turnover hydraulic cylinder 112 carried by the steel coil trolley 11 pushes the carbon steel coil, so that the carbon steel coil rolls off from the steel coil trolley 11 to the transition table and rolls along the transition table to the bearing table. Then the linear drive device drives the moving base 2 to move away from the steel coil trolley 11, so that the carbon steel coil can be temporarily placed on the bearing table, and the feeding channel of the stainless steel coil will not be blocked. Then the steel coil trolley 11 can transport the stainless steel coil on the second steel coil saddle 13 to the uncoiler 10. Then the carbon steel coil on the bearing table is lifted by the unmanned trolley to the first steel coil saddle 12 or the second steel coil saddle 13.

[0046] It can be seen that the present steel sleeve unloading system provides a temporary storage station, which avoids the problem of low production efficiency caused by the blocking of the feeding channel of the subsequent steel coil by the previous steel coil when the production plan order is corrected or changed.

[0047] It should be noted that the existing steel coil trolley 11 includes two rollers, and the steel coil or steel sleeve can be placed on the two parallel rollers, and the two rollers include a first roller 111 and a second roller 113. The turnover hydraulic cylinder 112 is fixedly installed on the steel coil trolley 11, and the cylinder end of the turnover hydraulic cylinder 112 is hinged to the first roller 111, which is used to drive the first roller 111 to lift to force the steel coil or steel sleeve to roll off from the steel coil trolley 11. The steel coil trolley 11 described above is a prior art, so its specific structure will not be described in detail.

[0048] In the present embodiment, as Figure 2 and Figure 3As shown, the bearing table comprises a first stand 204 and a second stand 206 arranged on the mobile base 2, the first stand 204 and the second stand 206 are arranged along the second direction and are parallel to each other. The first stand 204 is arranged adjacent to the transition table. The inner wall of the top of the first stand 204 and the second stand 206 are welded with a bearing pipe 205 for bearing the steel sleeve, the height of the bearing pipe 205 on the first stand 204 and the bearing pipe 205 on the second stand 206 is consistent. In this way, the steel sleeve rolled off the transition table will roll into the space between the first stand 204 and the second stand 206 along the transition table, and finally be stabilized between the two bearing pipes 205.

[0049] As a preferred embodiment, as shown in the drawings, Figure 3 As shown, the transition table comprises a support frame 201 and a blanking plate 3, wherein the support frame 201 is fixed on the mobile base 2, the top of the support frame 201 is welded with the blanking plate 3 extending along the second direction, and the end of the blanking plate 3 close to the first stand 204 is lower than the other end. That is, the blanking plate 3 is an inclined plate, and the end of the blanking plate 3 close to the first stand 204 is higher than the end close to the coil car 11. In this way, the steel sleeve rolled off the coil car 11 can roll onto the bearing table along the blanking plate 3.

[0050] Further, as shown in the drawings, Figure 3 As shown, the blanking plate 3 has a top surface, a first side surface and a bottom surface connected together, the bottom surface is fixed on the support frame 201, the included angle between the first side surface and the top surface is an acute angle, the first side surface faces the coil car 11, the second side surface faces the first stand 204, and the side of the top surface of the blanking plate 3 close to the first stand 204 is not lower than the upper surface of the bearing pipe 205. As shown in the drawings, Figure 5 The purpose of setting the end of the blanking plate 3 close to the coil car 11 into a pointed end is to ensure that the end of the blanking plate 3 is as close as possible to the second roller of the coil car 11, so that the pointed end of the blanking plate 3 is as close as possible to the space between the lower half of the steel sleeve and the second roller 113.

[0051] The steel sleeve blanking system also adds a slow-release mechanism 5, which comprises a vertical frame 202, a connecting rod 501, a plurality of wheel bodies 503 and a second hydraulic cylinder 504, wherein the vertical frame 202 is welded on the mobile base 2 and located on the side of the second stand 206 away from the first stand 204. A top pipe 203 is welded on the top of the vertical frame 202, and the second hydraulic cylinder 504 is fixedly installed on the right side of the top pipe 203, and the cylinder end of the second hydraulic cylinder 504 penetrates through the top pipe 203. The connecting rod 501 is fixed to the cylinder end of the second hydraulic cylinder 504 and is perpendicular to the second hydraulic cylinder 504, the connecting rod 501 is in a horizontal state, and a plurality of wheel bodies 503 are arranged on the connecting rod 501 along the axis direction of the connecting rod 501. Figure 3 ​

[0052] Thus, before the steel sleeve on the steel coil trolley 11 is pushed over, the second hydraulic cylinder 504 is elongated to drive the connecting rod 501 to gradually approach the steel sleeve on the steel coil trolley 11, until the wheel body 503 on the connecting rod 501 is attached to the surface of the steel sleeve. During the process of gradually pushing over the steel sleeve, the second hydraulic cylinder 504 is synchronously and gradually shortened to adapt to the action of the steel sleeve, thus playing the role of supporting the steel sleeve, so that the steel sleeve can be slowly pushed over, improving the safety. After the steel sleeve rolls onto the discharging plate 3, the second hydraulic cylinder 504 is gradually shortened to reduce the rolling speed of the steel sleeve, reduce its kinetic energy, avoid the steel sleeve from impacting the bearing table violently, and until the steel sleeve slowly and stably enters between the two bearing pipes 205 of the transition table, which also reduces the noise generated during the rolling of the steel sleeve.

[0053] As a preferred embodiment, as shown in the figure, two guide rods 502 are slidingly installed on the top pipe 203, the second hydraulic cylinder 504 is located between the two guide rods 502, and the same end of the two guide rods 502 is connected to the left side of the connecting rod 501. This arrangement ensures smooth movement of the connecting rod 501. Figure 2

[0054] As a preferred embodiment, as shown in the figure, a discharging rack 6, a crane guide rail, a third hydraulic cylinder 9 and at least one storage trolley 7 are arranged on the right side of the moving base 2, and the lifting hydraulic cylinder 702 and the storage trolley 7 are one-to-one corresponding. The discharging rack 6 is located on the right side of the moving base 2, and the length direction of the discharging rack 6 is parallel to the moving direction of the steel coil trolley 11. The crane guide rail is laid on the discharging rack 6, the storage trolley 7 includes a trolley body, a lifting hydraulic cylinder 702 and a bearing seat 701, wherein the rollers on both sides of the bottom of the trolley body slide on the crane guide rail, the lifting hydraulic cylinder 702 is fixedly installed on the trolley body, and the bearing seat 701 is fixedly installed on the top end of the lifting hydraulic cylinder 702. Figure 2 The crane guide rail includes two parallel square steels, and the two parallel square steels are welded on the discharging rack 6.

[0055] As shown in the figure, the third hydraulic cylinder 9 is located on the right side of the discharging rack 6, and the left end thereof is fixed on the trolley body, for pushing the storage trolley 7 to move along the length direction of the crane guide rail to approach or move away from the bearing table.

[0057] ​​​When the first hydraulic cylinder 4 is in the inactive state, the loading platform is in the initial position, and the first stand 204 and the second stand 206 on the loading platform are respectively aligned with the rear side and the front side of the blanking frame 6. After the steel coil on the uncoiler 10 is unwound, the steel coil trolley 11 takes the steel sleeve from the steel sleeve of the uncoiler 10, and then the first hydraulic cylinder 4 drives the moving base 2 to move on the ground rail 1 to approach the steel coil trolley 11, so that the blanking plate 3 is close to the steel coil trolley 11, and then the turnover hydraulic cylinder 112 of the steel coil trolley 11 pushes the steel sleeve, so that the steel sleeve falls from the steel coil trolley 11 to the blanking plate 3 and then rolls to the loading platform along the blanking plate 3, and then the first hydraulic cylinder 4 is shortened to pull the moving base 2 to move to the initial position away from the steel coil trolley 11. Then the third hydraulic cylinder 9 is elongated to a set length to drive the storage trolley 7 to move to the left until the storage trolley 7 moves to the position directly below the loading platform, and then the lifting hydraulic cylinder 702 of the storage trolley 7 is elongated to lift the steel sleeve on the loading platform, so that the steel sleeve falls into the loading seat 701 on the storage trolley 7. Subsequently, the third hydraulic cylinder 9 is shortened to pull the storage trolley 7 to retreat.

[0058] Optionally, a plurality of storage trolleys 7 are arranged, and the plurality of storage trolleys 7 are connected through the connecting rod 8. Figure 3 As shown, a square steel is welded on the bottom side of the first stand 204 and the bottom side of the second stand 206, and the two square steels are aligned with the above-mentioned crane guide rail. In addition, a long strip-shaped base is arranged on the left side of the ground rail 1, and two square steels are also welded on the base to enable the storage trolley 7 to move. That is, when the loading platform is in the initial position, the crane guide rail, the square steels at the bottom of the first stand 204 and the second stand 206, and the square steels on the base are aligned, the storage trolley 7 can move to the square steels at the bottom of the first stand 204 and the second stand 206, and finally move to the square steels on the base.
