Description

Technical Field

[0001] The utility model relates to the technical field of uncoilers, in particular to a replacement device for an expansion and contraction hydraulic cylinder of an uncoiler. Background Art

[0002] During the replacement of the expansion and contraction hydraulic cylinder on the uncoiler, the cylinder is located directly below the motor platform in a narrow space, has no hanging points, and has a short lifting height, making it unsuitable to use a hand chain hoist to directly lift the expansion and contraction hydraulic cylinder. Since the expansion and contraction hydraulic cylinder and the uncoiler mandrel pull rod are connected by fine threads, if there is no good support point for the expansion and contraction hydraulic cylinder during the disassembly process, the threads are easily damaged, making it impossible to reinstall normally. Even if the expansion and contraction hydraulic cylinder is removed, there is no flat surface for it to fall, which is very likely to cause collisions and personal injuries during the relocation process.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features.

[0028] An uncoiler is a specialized piece of equipment used to level sheet metal. It's used to level steel and uneven sheets. Depending on the configuration, it can be combined with an uncoiler, leveling, shearing, and other sheet product lines. The expansion and contraction hydraulic cylinder plays a crucial role in the uncoiler, providing stable pressure to support the weight of the coiled material while maintaining its position during the uncoiling process. During the uncoiling process, the cylinder adjusts the tension applied to the coiled material, ensuring it's neither too tight nor too loose during unwinding, thus preventing damage or deformation.

[0029] In the related art, when replacing the expansion and contraction hydraulic cylinder of the uncoiler, the expansion and contraction hydraulic cylinder is located directly below the motor platform, in a narrow space with no hanging points and a short lifting height. It is not suitable to use a hand winch to directly lift the expansion and contraction hydraulic cylinder. The expansion and contraction hydraulic cylinder needs to be moved outside the motor platform. The expansion and contraction hydraulic cylinder is heavy and difficult to carry. Since the expansion and contraction hydraulic cylinder and the uncoiler mandrel pull rod are connected by fine threads, if there is no good support point to support the expansion and contraction hydraulic cylinder during the disassembly process, the threads are easily damaged, resulting in the inability to reinstall normally. Even if the expansion and contraction hydraulic cylinder is removed, there is no flat surface for it to fall, and it is very easy to cause collisions or personal injuries during the relocation process.

[0030] In order to solve the above technical problems to a certain extent, an embodiment of the present application provides a device for replacing the expansion and contraction hydraulic cylinder of a uncoiler. During the disassembly process of the expansion and contraction hydraulic cylinder, the support mechanism supports the expansion and contraction hydraulic cylinder throughout the entire process, thereby greatly improving the situation where the threads between the expansion and contraction hydraulic cylinder and the pull rod are easily damaged, and collisions or personal injuries are very likely to occur during the reversing process.

[0031] The following describes the embodiments of the present application with reference to the accompanying drawings:

[0032] The embodiment of the present application provides a replacement device 10 for an expansion and contraction hydraulic cylinder of an uncoiler, which is used to assist in replacing the expansion and contraction hydraulic cylinder in the uncoiler. The uncoiler has an installation position for installing the expansion and contraction hydraulic cylinder. The replacement device 10 includes a main body 100 and a support mechanism 200. The main body 100 can be set below the installation position. The top surface of the main body 100 has a disassembly position 111 and a hoisting position 112, and the disassembly position 111 is set corresponding to the installation position; the support mechanism 200 is set on the top surface of the main body 100, which is used to support the expansion and contraction hydraulic cylinder and can drive the expansion and contraction hydraulic cylinder to move back and forth between the disassembly position 111 and the hoisting position 112.

[0033] The replacement process of the expansion and contraction hydraulic cylinder includes two steps: disassembly and reassembly, that is, disassembly first and then reassembly. When the expansion and contraction hydraulic cylinder needs to be disassembled, the expansion and contraction hydraulic cylinder is at the installation position. The replacement device 10 can be placed below the installation position, and the disassembly position 111 on the top surface of the main body 100 is set corresponding to the installation position. The support mechanism 200 is moved to the disassembly position 111 to support the expansion and contraction hydraulic cylinder. At this time, the thread between the expansion and contraction hydraulic cylinder and the pull rod can be disassembled. Since the support mechanism 200 supports the expansion and contraction hydraulic cylinder during the process of disassembling the thread between the expansion and contraction hydraulic cylinder and the pull rod, the support force can improve the situation where the thread is easily damaged during the disassembly process. After the expansion and contraction hydraulic cylinder is separated from the pull rod, the support mechanism 200 still continues to support the expansion and contraction hydraulic cylinder, thereby improving the situation of collision or personal injury accidents.

[0034] Since disassembly position 111 corresponds to the installation position, and the installation position is located directly below the motor platform, it is obvious that hoisting position 112 is outside the motor platform. Once the expansion and contraction hydraulic cylinder is separated from the pull rod, support mechanism 200 can drive the expansion and contraction hydraulic cylinder to hoisting position 112, and then the expansion and contraction hydraulic cylinder can be lifted away using the hand chain hoist, completing the disassembly process of the expansion and contraction hydraulic cylinder. Because the expansion and contraction hydraulic cylinder is moved to hoisting position 112 by support mechanism 200, no manual handling is required, thus avoiding laborious handling.

[0035] Similarly, when the expansion and contraction hydraulic cylinder needs to be reinstalled, the support mechanism 200 is moved to the lifting position 112, and the expansion and contraction hydraulic cylinder is placed on the support mechanism 200, and then the support mechanism 200 drives the expansion and contraction hydraulic cylinder to move to the disassembly position 111. Since the disassembly position 111 is set corresponding to the installation position, after the support mechanism 200 drives the expansion and contraction hydraulic cylinder to move to the disassembly position 111, the expansion and contraction hydraulic cylinder is located at the installation position. At this time, the expansion and contraction hydraulic cylinder and the pull rod can be connected to complete the reinstallation of the expansion and contraction hydraulic cylinder.

[0036] It should be noted that the height of the support mechanism 200 and its relative position with the pull rod in the horizontal plane need to be designed in advance to ensure that when the support structure moves to the disassembly and assembly position 111, the support structure can be supported on the expansion and contraction hydraulic cylinder during disassembly, and when reassembly, the expansion and contraction hydraulic cylinder can be located in the installation position and aligned with the pull rod.

[0037] In some embodiments, the disassembly position 111 and the hanging position 112 are arranged along the length direction of the main body 100 .

[0038] That is, disassembly position 111 and lifting position 112 are arranged along the length of the top surface of main body 100. Disassembly position 111 and lifting position 112 are arranged side by side. Lifting position 112 can be understood as an extension of disassembly position 111, so that lifting position 112 is located outside the motor platform to facilitate the lifting of the expansion and contraction hydraulic cylinder. In other words, the arrangement of disassembly position 111 and lifting position 112 requires a certain length. Therefore, disassembly position 111 and lifting position 112 are arranged along the length of main body 100.

[0039] Specifically, the shape of the top surface of the main body 100 can be rectangular, elliptical, etc., which is not limited.

[0040] In some embodiments, the support mechanism 200 includes a moving component 210 and a support member 220 arranged on the moving component 210. The support member 220 is used to support the expansion and contraction hydraulic cylinder. The support member 220 can drive the expansion and contraction hydraulic cylinder to move back and forth between the disassembly position 111 and the lifting position 112 through the moving component 210.

[0041] Specifically, support member 220 includes a support block that supports the expansion and contraction hydraulic cylinder. Furthermore, since the expansion and contraction hydraulic cylinder is generally cylindrical, the support block has an arcuate concave surface 221 that mates with the outer surface of the expansion and contraction hydraulic cylinder. The expansion and contraction hydraulic cylinder is mounted on arcuate concave surface 221, thereby ensuring a more stable installation of the expansion and contraction hydraulic cylinder.

[0042] In some embodiments, the moving assembly 210 includes a movable plate 211, a roller 212 and a guide rail 213, the guide rail 213 is arranged on the top surface of the main body 100, the roller 212 is arranged on both sides of the movable plate 211, the support block is arranged on the movable plate 211, and the roller 212 is slidably arranged on the guide rail 213 on the same side.

[0043] Obviously, the guide rail 213 is arranged along the length direction of the top surface of the main body 100 and covers the disassembly position and the hanging position 112, so that the movable plate 211 can slide on the guide rail 213 through the roller 212 to drive the support mechanism 200 to move between the disassembly position 111 and the hanging position 112.

[0044] Specifically, each side of the movable plate 211 is provided with two rollers 212. Of course, the number of rollers 212 provided on each side can also be three, four, etc. The more the number of rollers 212 is provided, the more stable the operation of the movable plate 211 is, and there is no limitation on this.

[0045] In some embodiments, the guide rail 213 has a clamping portion 213a, and the roller 212 has a clamping groove. The clamping portion 213a is located in the clamping groove, and along the width direction of the main body 100, the length of the clamping groove is greater than the length of the clamping portion 213a.

[0046] Since the length of the snap-in groove is greater than the length of the snap-in portion 213a along the width direction of the main body 100, that is, the snap-in portion 213a has a movable gap in the snap-in groove along the width direction of the main body 100, the snap-in portion 213a can be movably installed in the snap-in groove, thereby realizing sliding fit between the roller 212 and the guide rail 213.

[0047] In some embodiments, adjustment components 230 are provided on both sides of the movable component 210, and the adjustment component 230 includes a first connecting plate 231, a second connecting plate 232 and an adjusting top screw 233. The first connecting plate 231 is connected to the movable plate 211, the second connecting plate 232 is connected to the main body 100, and the adjusting top screw 233 is screwed to the second connecting plate 232 and abuts against the first connecting plate 231.

[0048] Although the relative position of the support mechanism 200 and the pull rod in the horizontal plane (i.e., the position of the support mechanism 200 in the width direction of the main body 100) has been designed in advance to ensure that when the support structure moves to the disassembly position 111, the expansion and contraction hydraulic cylinder can be located just in the installation position and aligned with the pull rod when reinstalled, but in actual conditions, slight errors may occur. Therefore, when reinstalling the expansion and contraction hydraulic cylinder, in order to ensure that the telescopic rod of the expansion and contraction hydraulic cylinder can be aligned with the pull rod to achieve connection with the pull rod, it is necessary to adjust the position of the support mechanism 200 in the width direction of the main body 100.

[0049] Because the engaging portion 213a has a movable gap in the engaging groove along the width direction of the main body 100, the engaging portion 213a can move in the engaging groove along the width direction of the main body 100, thereby reserving space for adjusting the position of the support mechanism 200 in the width direction of the main body 100. Since the first connecting plate 231 is connected to the movable plate 211, the second connecting plate 232 is connected to the main body 100, and the adjusting screw 233 is threadedly connected to the second connecting plate 232 and abuts against the first connecting plate 231, the adjusting screw 233 is threadedly driven in the second connecting plate 232, thereby pushing the movable plate 211 to move along the width direction of the main body 100 through the first connecting plate 231, thereby achieving adjustment of the position of the support mechanism 200 in the width direction of the main body 100.

[0050] In some embodiments, the main body 100 includes a mounting plate 110 and a plurality of support columns 120 disposed on a bottom surface of the mounting plate 110 , and the support mechanism 200 is disposed on the mounting plate 110 .

[0051] The mounting plate 110 is used as a mounting component for the support mechanism 200 and the expansion and contraction hydraulic cylinder. Multiple support columns 120 support the support mechanism 200 and the expansion and contraction hydraulic cylinder. The support columns 120 can be installed on the ground. Specifically, the mounting plate 110 can be rectangular, with four support columns 120 located at the four corners of the mounting plate 110 to provide stable support.

[0052] In some embodiments, the support column 120 includes a first support portion 121 and a second support portion 122 , and the first support portion 121 and the second support portion 122 are threadedly connected.

[0053] Although the height of the support mechanism 200 has been pre-designed to ensure that when the support structure moves to the disassembly position 111, the support structure can be properly supported by the expansion and contraction hydraulic cylinder during disassembly, slight errors may occur in actual situations. Therefore, to further ensure that the support structure can be properly supported by the expansion and contraction hydraulic cylinder during disassembly, the height of the main body 100 needs to be adjustable. Because the first support portion 121 and the second support portion 122 are threadedly connected, the threaded transmission between the first support portion 121 and the second support portion 122 can adjust the height of the support column 120, thereby adjusting the height of the main body 100 and, in turn, the height of the support structure.

[0054] Specifically, the first support part 121 is connected to the mounting plate 110 , the first support part 121 is a screw, and the second support part 122 includes a connected connecting column and a nut 122b. The first support part 121 is screwed into the nut 122b to realize the screw connection between the first support part 121 and the second support part 122.

[0055] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0056] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
