Description

Technical Field

[0001] The utility model belongs to the field of silicon steel coils, and in particular relates to a coil bearing device. Background Art

[0002] Silicon steel coils are the raw materials for producing transformer cores. The original silicon steel coils are divided into narrow coils of certain widths on the slitting line. Narrow coils of different widths need to be transported to the silicon steel shearing line for slicing before they can be further stacked into cores. With the development of transformer intelligent workshop technology, transformer core manufacturers have now established coil warehouses for the storage of silicon steel coils. Trolleys are usually used to transport coils between the slitting line and the coil warehouse, and between the coil warehouse and the silicon steel shearing line.

[0003] There are currently two structures used on the trolley to carry coils:

[0004] One is a V-shaped bracket, which supports the outer cylindrical surface of the coil for transportation through the centering function of the V-shaped bracket. The V-shaped bracket can achieve left and right centering. When the outer diameter of the coil is different, the center height of the coil will change. The other is a single-arm beam, where the inner circle of the coil is pressed on the top of the beam arm. This is a hanging method. When hanging materials on a single-arm beam, the coil may be hung off-center.

[0005] In addition, when the above two structures are used to transport coils that are not compact enough or when the outer diameter of the coil is small (the coil is thin), the silicon steel coil has poor rigidity and is prone to deformation. The inner circle of the coil changes from a circle to an ellipse, and collisions may occur during docking, affecting the smooth docking of the trolley with other equipment. Utility Model Content

[0046] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0047] It should be noted that, in the present utility model, the top, bottom, left and right in the figure are regarded as the top, bottom, left and right of the coil material carrying device described in this specification.

[0048] The exemplary embodiments of the present invention are now introduced with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0049] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0050] This embodiment relates to a coil material carrying device suitable for a transfer vehicle, particularly a silicon steel transfer vehicle for the transformer core industry, see Figure 1 The coil material carrying device includes a frame 100, a cantilever support 300, and a linear drive mechanism 400.

[0051] In some embodiments, a whole steel plate with a thickness of 50 mm is used as the frame 100 .

[0052] The cantilever support 300 is installed on the frame 100. Figure 3 As shown, the cantilever support 300 is suitable for hanging the coil 500 , and the cantilever support 300 includes at least two side support arms 320 , and the side support arms 320 are slidably mounted on the frame 100 .

[0053] The linear drive mechanism 400 drives the side support arms 320 to slide along the frame 100 to change the distance between the two side support arms 320. When the linear drive mechanism 400 drives the two side support arms 320 to move toward each other, the overall size of the cantilever bracket 300 is reduced, which facilitates the insertion of the load-bearing device into the inner circle of the coil 500 on other equipment for material removal; when the linear drive mechanism 400 drives the two side support arms 320 to move away from each other, the cantilever bracket 300 is supported on the inner circle of the coil 500, and the inner circle of the coil 500 is supported into a centered full circle.

[0054] Since the overall size of the cantilever bracket 300 is variable, the carrying device can prevent the coil from hanging off-center and ensure the consistency of the center when the coil is transferred. It can also hang coils with poor rigidity and support their inner circles to prevent them from deforming, thereby ensuring the accuracy and reliability of coil docking. Therefore, the range of coils carried is wider and the adaptability is stronger.

[0055] In order to achieve the cantilever support 300 sliding along the rack 100, please refer to Figure 3 The coil material carrying device also includes a sliding mechanism 200, which has at least a linear guide rail 210 installed on the frame 100, and a slider 220 is slidably provided on the linear guide rail 210, and the slider 220 is connected to the side support arm 320 and the linear drive mechanism 400.

[0056] In some embodiments, in order to improve stability during the sliding process, two linear guide rails 210 are provided, and the two linear guide rails 210 are arranged in parallel. The slider 220 can slide along the two linear guide rails 210. Specifically: the linear drive mechanism 400 provides power to drive the side support arm 320 to slide along the linear guide rail 210 through the slider 220.

[0057] In order to facilitate disassembly, a transition plate 110 is detachably mounted on the frame 100 , and the linear guide rail 210 is mounted on the transition plate 110 .

[0058] The cantilever support 300 includes an upper arm 310 and a side support arm 320 .

[0059] The first end of the lifting arm 310 is fixed to the frame 100 , and the second end is cantilevered to hang the coil 500 .

[0060] The side support arms 320 are arranged on both sides of the orthographic projection of the upper arm 310 , and the first end of each side support arm 320 is fixed to the slider 220 , and the second end is cantilevered to hang the coil 500 . That is, the side support arms 320 are located on both sides below the upper arm 310 .

[0061] Please continue reading Figure 3 When the coil 500 is hung on the upper lifting arm 310 and the side supporting arm 320, the upper lifting arm 310 and the side supporting arm 320 jointly support the inner circle of the coil 500, and support the inner circle of the coil into a centered full circle.

[0062] The first end mentioned above and below refers to the end close to the rack 100, which can be understood as the proximal end with the rack 100 as a reference, while the second end refers to the end far away from the rack 100, that is, the distal end.

[0063] In some embodiments, see Figure 1 and Figure 3 The number of the side support arms 320 is two. The orthographic projection of the upper lifting arm 310 is the symmetry axis, and the two side support arms 320 are symmetrically arranged about the symmetry axis, that is, the distal ends of the upper lifting arm 310 and the two side support arms 320 are distributed in a three-point manner, and the connecting line is a triangle. This arrangement can support the inner circle of the coil into a centered full circle, avoid the coil from hanging off-center, ensure the consistency of the center when the coil is transferred, and can also suspend the coil with poor rigidity to support its inner circle to prevent its deformation.

[0064] Each side support arm 320 is equipped with a sliding mechanism 200. Therefore, when there are two side support arms 320, the two sliding mechanisms 200 are arranged on both sides of the upper arm 310. The linear drive mechanism 400 drives the two side support arms 320 to slide along their respective sliding mechanisms 200, so as to realize the two side support arms 320 to be spread outward or retracted inward. Specifically:

[0065] When the two side support arms 320 retract inward (move toward each other), it is convenient for the carrying device to be inserted into the inner circle of the coil on other equipment to perform material picking operations; when the two side support arms 320 are spread out to both sides (move away from each other), the upper edge of the upper arm 310 and the edges of the two side support arms 320 jointly support the inner circle of the coil 500, supporting the inner circle of the coil into a centered full circle.

[0066] In some embodiments, the side support arm 320 includes a base plate 321, an arm 322 and a rib plate 323. The base plate 321 is fixed to the slider 220; the first end of the arm 322 is fixed to the base plate 321, and the second end is cantilevered to hang the coil 500; the rib plate 323 is vertically fixed to the base plate 321 and the slider 220.

[0067] The rib plate 323 can increase the contact area between the side support arm 320 and the slider 220 and improve stability.

[0068] A through hole suitable for the linear drive mechanism 400 to pass through is defined at the first end of the lifting arm 310 .

[0069] The linear drive mechanism 400 is at least one of an oil cylinder, an air cylinder, and an electric cylinder.

[0070] In some embodiments, Figure 1 or Figure 3As shown, there are two side support arms 320, one end of the linear drive mechanism 400 is connected to the left side support arm 320, and the other end of the linear drive mechanism 400 is connected to the right side support arm 320. Specifically, the linear drive mechanism 400 adopts a cylinder, and the two ends of the cylinder are respectively connected to the inner sides of the two side support arms 320 through hinges. The cylinder is extended and shortened through a hydraulic electromagnetic reversing valve, thereby controlling the support arms on both sides to open to the sides or retract inward.

[0071] When the linear drive mechanism 400 adopts an oil cylinder, the coil carrying device is also provided with an outer movable limit device 600 and an inner movable limit device, wherein the outer movable limit device 600 is placed on the outer side of the sliding mechanism 200 (away from the upper arm 310), and its purpose is to limit the extreme position of the outward movement of the two side support arms 320; the inner movable limit device is a limit rod, and the length of the limit rod is symmetrical about the center of the upper arm 310. When the side support arms 320 move inward along the linear guide rail 210, it is ensured that the two side support arms 320 are symmetrical about the upper arm 310 when they are closed, which is convenient for insertion into the docking port of the docking device.

[0072] Specifically, if Figure 2 As shown, the coil material carrying device also includes an outer movable limiting device 600 configured on each sliding mechanism 200, and the outer movable limiting device 600 includes a limiting block, a limiting bolt and a nut. The limiting block is installed on the transition plate 110 and away from the upper arm 310; the limiting bolt is screwed through the limiting block, and the limiting bolt is screwed to abut or disengage from the slider 220.

[0073] That is to say, the limit block is provided with a threaded hole, and the limit bolt is screwed into the threaded hole. By adjusting the screw-out length of the limit bolt, the limit position of the support arms 320 on both sides moving outward can be adjusted.

[0074] The coil material carrying device also includes an inner movable limiting device, which is a limiting rod fixed to the frame 100 or the transition plate 110. The limiting rod passes through the through hole opened at the first end of the lifting arm 310 to limit the position of the slider 220 sliding to the lifting arm 310.

[0075] In some embodiments, the inner movable limit device is a steel column, the length of both sides of the steel column is symmetrical about the center of the upper arm 310, and the total length matches the retraction length of the cylinder to ensure that the side support arm 320 is symmetrical about the upper arm 310 when retracted.

[0076] The contact area between the lifting arm 310, the side support arm 320 and the inner circle of the coil 500 is an arc surface, the curvature of which is consistent with the curvature of the inner circle of the coil, and its purpose is to increase the load-bearing contact area to prevent damage to the coil.

[0077] In some embodiments, the linear drive unit 400 uses two electric cylinders (electric push rods), and the two electric cylinders pass through the holes at the root of the upper arm 310 and extend to the left and right respectively. The electric cylinder is fixedly connected to the upper arm 310 or the frame 100 by bolts. The extension shafts of the two electric cylinders are respectively connected to the inner sides of the left and right support arms 320 through hinge structures. Each electric cylinder can control the connected side support arms 320 to move left and right along the linear guide rail 210. When working, the two electric cylinders push the two side support arms 320 to move in opposite directions, so as to realize the opening and closing of the side support arms 320. By controlling the moving distance of the extended end of the electric cylinder, it can be ensured that in the open or closed state, the two side support arms 320 are symmetrical about the upper arm 310, and in the open state, the two sides of the side support arms 320 and the upper side of the upper arm 310 together form a full circle.

[0078] This coil material bearing device can avoid the coil material from hanging off-center, ensure the consistency of the center when the coil material is transferred, and can also hang the coil material with poor rigidity, support its inner circle to prevent its deformation from affecting the coil material transfer and docking, and ensure the accuracy and reliability of the coil material docking. Therefore, the range of coil materials carried is wider and the adaptability is stronger.

[0079] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
