DETAILED DESCRIPTION

[0023] In the prior art, the equipment used for steel coil tower repair is small in tonnage and can only repair the tower of the inner three circles of the steel coil below 8mm. It has no good repair effect on staggered layers, outer towers or thicker inner towers.

[0024] Repairing staggered layers, outer towers or thicker inner towers requires a clamping force of more than 400 tons. In related technologies, most steel coil tower repair machines use multiple guide rods and a central single cylinder to apply pressure. If a large-tonnage steel coil tower repair machine is designed in this way, there are many problems. Because using a single cylinder to apply pressure requires a single cylinder to reach a force of more than 400 tons, and the cylinder diameter under this pressure requirement is very large (for example, under a system pressure of 250MPa, the cylinder diameter reaches more than 600mm), or in the case of a small cylinder diameter, the system pressure is very large (for example, a cylinder diameter of 320mm requires a pressure of more than 520MPa), which not only causes difficulties in design and manufacturing, but also in the case of unbalanced force in the multi-guide rod arrangement, equipment failures such as gnawing of the guide rails are prone to occur.

[0025] This embodiment provides a strong steel coil tower repair machine, please refer to Figure 1 , including a frame 1, two platens, a driving mechanism and a transport trolley 4. The two platens are facing each other, and a tower-shaped repair space for the steel coil 3 is formed between the two platens. At least one of the two platens belongs to a mobile platen 2, and the mobile platen 2 is driven by a driving mechanism. The platen is a working mechanism for pushing the steel coil 3. Under the action of the driving mechanism, the platen reciprocates and squeezes the end surface of the steel coil 3 to achieve the tower-shaped repair of the steel coil 3. The frame 1 is used as a body for placing the platen, and bears the supporting force required when the platen is working.

[0026] Please refer to Figure 1 The driving mechanism includes a central guide assembly and a plurality of driving cylinders 5. The central guide assembly includes a guide inner rod 11 and a guide outer cylinder 12. The guide outer cylinder 12 is fixedly connected to the frame 1. The guide inner rod 11 is movably arranged in the guide outer cylinder 12. The guide inner rod 11 is fixedly connected to the movable platen 2. The guide inner rod 11 and the guide outer cylinder 12 provide a guiding effect on the movement process of the movable platen 2. A plurality of driving cylinders 5 are arranged at intervals outside the guide outer cylinder 12. The two ends of the driving cylinders 5 are hinged to the frame 1 and the movable platen 2, respectively. Among them, the carrying trolley 4 is used to carry the steel coil 3, so that the steel coil 3 enters the tower-shaped repair space of the steel coil 3, and is moved out of the space after the repair is completed.

[0027] In some embodiments, please refer to Figure 1 and Figure 4 , the transport trolley 4 moves along the fixed track to transport the steel coil 3 back and forth. At the beginning, the transport trolley 4 is located outside the frame 1, and the steel coil 3 to be repaired is hoisted onto the saddle of the transport trolley 4, and then the steel coil 3 to be repaired is transported to the center of the pressure plate according to the instruction, and the pressure plate squeezes and repairs the steel coil 3 according to the instruction. After the pressure plate completes the repair, the transport trolley 4 returns to the initial position with the steel coil 3.

[0028] As described above, this solution adopts a design method of arranging multiple small-diameter driving cylinders 5 on the periphery of the central guide assembly. On the one hand, it is easy to achieve the required pressure, and on the other hand, it avoids the problem of more than two guide rods being stuck due to processing accuracy.

[0029] In this solution, the central guide assembly can be set with a large diameter. In some embodiments, the guide inner rod 11 is set in a cylindrical shape, and the guide inner rod 11 located at the center of the pressure plate is slidably connected to the guide outer cylinder 12 at the center of both sides of the frame 1. This solution reasonably increases the number of drive cylinders 5 by arranging multiple drive cylinders 5 on the periphery of the central guide assembly, so that the drive cylinder 5 can be selected with a small cylinder diameter, thereby reducing the difficulty in design and processing and manufacturing.

[0030] The tower repair machine of the present application uses multiple oil cylinders to apply force and stable guidance through the middle guide cylinder to complete the large-tonnage extrusion of the steel coil 3 and achieve strong repair, which has the advantages of simple structure and reliable operation. On the whole, this solution not only provides a reliable power source, but also has sufficient support strength to meet the huge tensile force generated by repairing the tower-shaped steel coil 3, and solves the repair problems of staggered layers, outer towers and thicker inner towers of steel coils 3.

[0031] In some embodiments, a plurality of driving cylinders 5 are evenly spaced in sequence along the circumference of the center guide assembly. The center guide assembly is evenly stressed and easy to process and manufacture through the design of center guidance and circumferentially evenly arranged cylinders.

[0032] At least one of the two pressure plates is a mobile pressure plate 2. In some embodiments, please refer to Figure 1 , both pressure plates belong to the mobile pressure plate 2, and two sets of driving mechanisms need to be configured, and the driving mechanisms are both installed on the frame 1. In some embodiments, please refer to Figure 2 Among the two pressure plates of the strong steel coil tower repair machine, one belongs to the mobile pressure plate 2 and the other belongs to the fixed pressure plate 8, which is fixedly installed on the frame 1.

[0033] In some embodiments, see Figure 1 and Figure 2 , the two pressure plates are arranged opposite to each other. In some embodiments, please refer to Figure 3 , the two pressure plates are arranged vertically opposite to each other.

[0034] In some embodiments, see Figure 1 The strong steel coil tower repair machine also includes a hydraulic station 6, which is connected to the driving cylinder 5. The hydraulic station 6 can be fixedly installed on the frame 1, and the hydraulic station 6 provides power for the cylinder.

[0035] In the related art, the frame 1 of the steel coil tower repair machine is a split type, and the pressure needs to be partially or completely transmitted to the frame 1 base through the frame 1, which requires corresponding ground foundation strength to ensure, which not only increases the cost and difficulty of construction, but also poses a safety hazard to large-tonnage pressure equipment.

[0036] Therefore, in some embodiments, the frame 1 is an integral frame 1 that is a rigid body, which is defined as a rigid frame formed by welding, cast welding or bolt connection. The other structures of the strong steel coil tower repair machine are installed on this integral frame 1, so that the huge compression force generated by repairing the tower of the steel coil 3 is borne by the integral frame 1. The frame 1 can support the huge extrusion force generated when repairing the tower of the steel coil 3. The ground foundation is only used to support the weight of the whole machine to avoid the ground foundation from bearing the tensile force during operation.

[0037] Due to the high pressure of the steel coil tower repair machine, the cylinder diameter is relatively large, and the cylinder stroke is long due to the need to meet the needs of steel coils of different specifications. The long cylinder stroke requires a large flow rate of the hydraulic system pump station, which will significantly increase the manufacturing cost. In some embodiments, please refer to Figure 1The strong steel coil tower repair machine also includes an auxiliary oil cylinder 7, and the two ends of the auxiliary oil cylinder 7 are respectively connected to the frame 1 and the guide inner rod 11, so that the auxiliary oil cylinder 7 and the driving oil cylinder 5 move synchronously. In the case of an empty stroke of the driving oil cylinder 5, such as an empty stroke such as adjusting the distance or returning the steel coil 3, the auxiliary oil cylinder 7 is used to push the driving oil cylinder 5 to quickly complete the predetermined stroke, which can greatly reduce the rated flow of the pump station and reduce costs. In this solution, the cylinder diameter of the auxiliary oil cylinder 7 is small, which realizes the operation mode of the auxiliary oil cylinder 7 with a smaller cylinder diameter pushing the driving oil cylinder 5, and the pressure plate can quickly complete the predetermined stroke under a small flow.

[0038] In some embodiments, see Figure 5 The saddle for placing the steel coil 3 on the transport trolley 4 is set as a movable saddle 9, and an adjusting oil cylinder 10 is also set on the transport trolley 4. The movable saddle 9 is slidably mounted on the track on the transport trolley 4. One end of the adjusting oil cylinder 10 is hinged to the movable saddle 9, and the other end is fixed to the transport trolley 4. Its function is to prevent the steel coil 3 from sliding along the saddle support surface and damaging the surface of the steel coil 3 when the pressure plate squeezes the steel coil 3.

[0039] For details, please refer to Figure 5 , the movable saddle 9 on which the steel coil 3 is placed can slide along the track on the transport trolley 4, and the movable saddle 9 moves with the adjusting cylinder 10, and its position on the track can be adjusted. When transporting the coil, the adjusting cylinder 10 is in a fixed state, and the position of the movable saddle 9 is also fixed. When the movable pressure plate 2 begins to squeeze the steel coil 3, the oil inlet and outlet of the adjusting cylinder 10 are opened, and the piston rod of the adjusting cylinder 10 is in a floating state, so that the movable saddle 9 carrying the steel coil 3 can move with the steel coil 3. After the repair is completed, the oil inlet and outlet of the adjusting cylinder 10 are restored to the oil, and the saddle is reset according to the system instructions.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
