Description

Technical Field

[0001] This utility model relates to the field of safety limit technology for steel coil transfer, and more specifically, to a transfer device for steel coil production. Background Technology

[0002] Steel coils, also known as rolled steel, are formed by hot or cold pressing of steel into coils. These coils are used for easy storage and transportation, and for various processing methods, such as turning them into steel plates or strips. Formed coils are mainly hot-rolled and cold-rolled. Hot-rolled coils are processed products before the recrystallization of steel billets. Cold-rolled coils are a subsequent processing of hot-rolled coils. Steel coils typically weigh around 15-30 tons.

[0003] Currently, automatic transfer of steel coils is carried out using trackless electric flatbed carts. V-shaped platforms are welded onto the placement platform of the electric flatbed cart to support the steel coils. The electric flatbed cart then moves the steel coils to a fixed area for storage or further processing according to a pre-set program. However, if there are sharp turns or emergency obstacle avoidance scenarios during the transfer process, the stability of the steel coils can be easily compromised, and the simple V-shaped platform support poses a safety hazard.

[0004] The announcement number CN212950347U proposes an electric flatcar for steel coil transfer. Although the device can limit the position of the steel coil during the transfer process, the limiting method is not convenient enough, and manual operation is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a transfer device for steel coil production.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A transfer device for steel coil production includes a trackless electric flatcar with several V-shaped platforms, a limit plate, a mounting box, a servo motor, connecting rollers, mounting rods, and an automatic pressing assembly.

[0008] Several limiting plates are vertically welded to the platform of the trackless electric flatbed, and the limiting plates are staggered with the V-shaped platform.

[0009] The mounting box is fixed to the top of the limit plate, and a servo motor is installed inside the mounting box;

[0010] A connecting roller is welded to one end of the mounting rod. The connecting roller is connected to the motor shaft of the servo motor via a coupling. An automatic pressing component that fits against the outer circle of the steel coil is also installed on the mounting rod.

[0011] Furthermore, the automatic pressing assembly includes a telescopic cylinder and an arc-shaped plate.

[0012] The telescopic cylinder is fixed to the other end of the mounting rod;

[0013] The arc-shaped plate is connected to the telescopic cylinder and is in contact with and fits against the outer circle of the steel coil.

[0014] Furthermore, a U-shaped limiting rod is welded to one end of the V-shaped platform, which contacts one end face of the steel coil.

[0015] Furthermore, both the limiting plate and the limiting rod are made of weathering steel plate, and the weathering steel plate is covered with a polyurethane layer.

[0016] Furthermore, the surface of the V-shaped platform is provided with polyurethane rubber.

[0017] Furthermore, the inner wall of the arc-shaped plate is provided with polyurethane rubber.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared to existing technologies, the limiting plate in this application can radially limit the movement of the steel coil to prevent it from detaching from the V-shaped platform when making sharp turns or avoiding obstacles. The pressing component can limit the axial and radial orientation of the steel coil respectively, and does not obstruct it when the steel coil is hoisted and placed. As a result, the stability of the steel coil when making sharp turns or avoiding obstacles is enhanced, and the safety hazards are significantly reduced. At the same time, the automation of the limiting process during the steel coil transfer is improved, making the operation convenient and fast, and effectively reducing the labor intensity of manual operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0025] like Figure 1 and Figure 2 As shown, a transfer device for steel coil production includes a trackless electric flatcar 1 (which is existing technology and will not be improved). The trackless electric flatcar 1 is equipped with several V-shaped platforms 2, and also includes a limit plate 3, a mounting box 4, a servo motor, connecting rollers 5, mounting rods 6, and an automatic pressing component.

[0026] Several limiting plates 3 are vertically welded to the platform of the trackless electric flatbed 1, and the limiting plates 3 and the V-shaped platform 2 are staggered.

[0027] Mounting box 4 is fixed on the top of limit plate 3, and a servo motor is installed inside mounting box 4;

[0028] One end of the mounting rod 6 is welded with a connecting roller 5. The connecting roller is connected to the motor shaft of the servo motor through a coupling. The mounting rod 6 is also equipped with an automatic pressing assembly that fits against the outer circle of the steel coil (the coupling and the servo motor are not shown in the figure).

[0029] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the automatic pressing assembly includes a telescopic cylinder 7 and an arc-shaped plate 8.

[0030] The telescopic cylinder 7 is fixed to the other end of the mounting rod 6;

[0031] The arc-shaped plate 8 is connected to the telescopic cylinder 7, and the arc-shaped plate 8 is in contact with and fits against the outer circle of the steel coil.

[0032] In order to limit the placement area of ​​the steel coil on the V-shaped platform 2, a further optimization of the above embodiment is that a U-shaped limiting rod 9 that contacts one end face of the steel coil is welded to one end of the V-shaped platform 2.

[0033] In a further refinement of the embodiment of this utility model, both the limiting plate 3 and the limiting rod 9 are made of weathering steel plate, and the weathering steel plate is covered with a polyurethane layer. The weathering steel plate has a long service life, and the polyurethane layer can both buffer the impact and reduce the probability of the steel coil surface being scratched.

[0034] To reduce wear on the steel coil surface caused by the V-shaped platform 2 and the arc plate 8, the above embodiment is further optimized by providing polyurethane rubber (not shown in the figure) on the surface of the V-shaped platform 2 and the inner wall of the arc plate 8.

[0035] It should be noted that both the servo motor and the telescopic cylinder 7 are electrically connected to the controller, which is not labeled in the figure.

[0036] The working process of this utility model:

[0037] First, the steel coils are hoisted and placed sequentially on V-shaped platforms 2, one coil at a time. Initially, the coil is placed from the end of the platform away from the limiting rod 9. Once one end face of the coil contacts the limiting rod 9 and is stably upright, the hoisting is released. After all the coils are placed and supported, the controller operates several servo motors to rotate 90 degrees, causing the pressing component to move just above the steel coils (as per the instruction manual). Figure 2 As shown in the figure, the telescopic cylinder 7 is then controlled by the controller to press down the outer circle of the steel coil and thus limit its position. It should be noted that the mounting rods 6 do not collide with each other during the deflection process and the rotation direction of each servo motor can be preset in the controller.

[0038] The limiting plate 3 can perform radial limiting to prevent the steel coil from detaching from the V-shaped platform 2 when making sharp turns or avoiding obstacles. The pressing component can limit the axial and radial orientation of the steel coil respectively, thereby enhancing the stability of the steel coil when making sharp turns or avoiding obstacles and significantly reducing safety hazards. At the same time, it improves the automation of the limiting process during the steel coil transfer, making the operation convenient and fast, and eliminating the need for long-term manual intervention.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
