Description

Technical Field

[0001] This invention relates to the field of steel coil transportation technology, and in particular to a stainless steel coil transportation and unloading device. Background Technology

[0002] Stainless steel coils are an important metal material widely used in various industries such as petroleum, chemical, construction, pharmaceutical, food, and machinery. Stainless steel coils are products with coiled form made from stainless steel strips as the base material through processes such as hot rolling, cold rolling, or hot rolling and pickling. These processes enable stainless steel coils to have the required thickness, width, and shape to meet the needs of different industries.

[0003] The transportation and unloading of stainless steel coils is a process involving multiple links and factors. Its purpose is to ensure that the stainless steel coils maintain their integrity and quality during transportation, while facilitating quick and efficient unloading at the destination. However, existing transportation and unloading technologies have many shortcomings. The steel coils are not equipped with buffer mechanisms when placed, making them prone to bumps and knocks. Furthermore, the existing devices do not have side protection mechanisms, posing a risk of side slippage. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention discloses a stainless steel coil conveying and unloading device, which effectively solves the problems in the background art. During use, this invention provides vertical and horizontal buffering during coil unloading, ensuring the coil is placed on the device at a uniform speed, preventing damage to the equipment or the coil itself from sudden contact. The buffering device also features an anti-deviation function. When one end of the coil deviates, that end will contact the pressure sensor first, causing a significant difference in pressure values ​​between the two sensors. The system corrects this deviation by actively compressing the side buffer plate under the side with higher pressure, increasing the preload of the compression spring II, strengthening the elasticity at that end, and slowing the descent speed of the coil, thus achieving balance. Furthermore, this invention includes a linked side fixing mechanism. When the coil is placed, the descent of the side buffer plate causes the extension of the arc-shaped side support, which limits and fixes the side of the coil, increasing the stability during transport.

[0005] A stainless steel coil conveying and unloading device includes a uniform speed buffer mechanism, an anti-tilting mechanism, and a linkage side fixing mechanism. The uniform speed buffer mechanism includes a central buffer plate, side buffer plates, pressure sensors, compression springs II, a base plate, retaining rings, and a horizontal buffer assembly. The slide rod at the lower end of the central buffer plate is slidably installed in a circular hole on the base plate. Two side buffer plates are provided, and the slide rods at the lower end of the side buffer plates are also slidably installed in circular holes on the base plate. Two pressure sensors are provided, which are respectively fixedly embedded in the side buffer plates on both sides. Four compression springs II are provided. The two middle compression springs II are installed on the slide rods at the lower end of the central buffer plate, and the two compression springs II on both sides are installed on the slide rods at the middle of the lower end of the side buffer plates. The upper ends of the two middle compression springs II are in contact with the central buffer plate, and the lower ends are in contact with the base plate. The upper ends of the two compression springs II on both sides are in contact with the side buffer plates, and the lower ends are in contact with the retaining rings. The retaining rings are slidably installed in a groove on the base plate.

[0006] Preferably, the lower end of the side buffer plate is provided with a toothed rack.

[0007] Preferably, the horizontal buffer assembly includes: a support plate, a limiting frame, a baffle, and a compression spring I; the slide rod on the limiting frame is slidably installed in the round hole on the baffle, the baffle is fixedly welded to the support plate, and the compression spring I is installed on the short shaft on the limiting frame, with one end of the compression spring I in contact with the limiting frame and the other end of the compression spring I in contact with the baffle.

[0008] Preferably, the anti-tilting mechanism includes: a rack frame, a drive shaft I, a pinion, and a self-locking drive assembly; the rack frame is slidably mounted in a groove on the base plate, the pinion meshes with the rack frame, the pinion is fixedly mounted on the drive shaft I, and the drive shaft I is rotatably mounted in a circular hole on the support plate.

[0009] Preferably, the self-locking drive assembly includes: a worm gear, a worm wheel, and a stepper motor; the worm gear is rotatably installed in a circular hole under the support plate, and the worm gear meshes with the support plate; the worm wheel is fixedly installed on the transmission shaft I; one end of the worm gear is fixedly connected to the motor shaft of the stepper motor; and the stepper motor is fixedly installed under the support plate.

[0010] Preferably, the linkage-side fixing mechanism includes: a vehicle body, a support block, a support column, an arc-shaped slide rail, an arc-shaped side bracket, a drive shaft II, an internal gear, and an external gear; the support block is fixedly installed on the vehicle body, the support column is fixedly welded to the four corners of the vehicle body, and the support column is fixedly connected to the bottom of the support plate; the arc-shaped slide rail is fixedly installed on the support block, the arc-shaped side bracket is slidably installed in the arc-shaped slide rail, and the spur teeth of the inner ring of the arc-shaped side bracket mesh with the internal gear; the internal gear is fixedly installed on the outer end of the drive shaft II, the drive shaft II is rotatably installed in the round hole of the extension plate under the bottom plate, the external gear is fixedly installed in the middle of the drive shaft II, and the external gear meshes with the rack at the lower end of the side buffer plate.

[0011] Preferably, the retaining ring is made of titanium alloy.

[0012] Preferably, one end of the rack holder has an inclined surface.

[0013] The advantages of this invention compared to the prior art are: When in use, this invention can buffer the steel coil in both the vertical and horizontal directions during unloading, thereby placing the steel coil on the device at a uniform speed and preventing damage to the equipment or the steel coil from sudden contact.

[0014] The buffer device of the present invention is also equipped with an anti-deviation function. When one end of the steel coil deviates, the steel coil at this end will contact the pressure sensor at this end first, resulting in a large difference in the pressure values ​​of the pressure sensors on both sides. The system will correct this deviation by actively compressing the side buffer plate under the side with higher pressure, thereby increasing the preload of the compression spring II, enhancing the elasticity at this end, slowing down the descent speed of the steel coil at this end, and thus making the steel coil balanced.

[0015] The present invention also includes a linked side fixing mechanism. When the steel coil is placed, the descent of the side buffer plate will cause the arc-shaped side support to extend, thereby limiting and fixing the side of the steel coil, thus increasing the stability of the steel coil during transportation.

The external gear 24 is fixedly installed in the middle of the drive shaft II 22. The external gear 24 meshes with the rack at the lower end of the side buffer plate 6.

[0035] In one optional embodiment of the present invention, such as Figure 7 As shown, the retaining ring 10 is made of titanium alloy.

[0036] In one optional embodiment of the present invention, such as Figure 5 , Figure 7 As shown, one end of the rack frame 11 has an inclined surface.

[0037] Working principle: In use, the steel coil is hoisted to the top of the device by a crane and then slowly lowered, so that the bottom end of the steel coil contacts the top of the central buffer plate 5 and the side buffer plate 6, and the two sides of the steel coil contact the curved surface of the limiting frame 2. As the steel coil continues to descend, the limiting frame 2 is squeezed to the sides, and the preload of the compression spring I4 gradually increases, increasing the stress of the limiting frame 2 on the steel coil. This provides a buffering effect while ensuring the stability of the steel coil. The lower end of the steel coil presses down on the central buffer plate 5 and the side buffer plate 6, thus providing vertical buffering until the extension plates on the sides of the central buffer plate 5 and the side buffer plate 6 are locked onto the top of the support plate 1, which greatly enhances the stability of the steel coil during placement. During the placement of the steel coil, unevenness can occur, potentially leading to instability or even detachment if no measures are taken. Therefore, the anti-tilt mechanism of this device is activated. When the steel coil is lowered and initially contacts the pressure sensors 7 on the two side buffer plates 6, if the coil is offset, the pressure readings from the two sensors 7 will differ significantly. The end with the higher reading and the one that displays the value first indicates a lower position. Therefore, the side buffer plate 6 at that end needs to increase its elasticity to slow the descent of that end of the coil until the pressure readings at both ends are balanced. Specifically, the side buffer plate 6 with the higher pressure reading needs to increase its elasticity. This slows the descent speed of that end of the coil until the pressure readings at both ends are balanced. The stepper motor 16 at one end starts, thereby driving the worm 14 to rotate. The worm 14 drives the worm wheel 15 to rotate, which in turn drives the transmission shaft I 12 to rotate. The pinion 13 on the transmission shaft I 12 drives the rack frame 11 to slide towards the retaining ring 10. The inclined surface of the rack frame 11 presses the retaining ring 10 to slide upward, thereby compressing the compression spring II 8 and increasing the elastic force of the compression spring II 8, thereby slowing down the descent of the steel coil at this end, so that the steel coil gradually reaches balance. The meshing relationship between the worm 14 and the worm wheel 15 has self-locking properties, preventing the pressure of the steel coil from causing a reaction force on the rack frame 11.

[0038] When in use, this device is also equipped with a linkage side fixing mechanism. When the side buffer plate 6 is pressed down, the rack at the lower end of the side buffer plate 6 drives the external gear 24 to rotate, thereby driving the internal gear 23 to rotate. The diameter of the internal gear 23 is larger than that of the external gear 24, so that the circumference of the internal gear 23 is longer. This causes the internal gear 23 to drive the arc-shaped side bracket 21 to extend to the designated position, limiting and fixing the side of the steel coil, thereby increasing the stability of the steel coil during transportation.
