Description

Technical Field

[0001] This utility model relates to the field of graphite product molding technology, and in particular to a 180° rotating device for a heavy hammer. Background Technology

[0002] In the manufacturing process of graphite cathode products, forming is a crucial step, which typically requires the use of a weight for compression. The bottom of the weight is fitted with specific forming structures, which vary depending on the type of graphite cathode product to be produced. This means that during production, when switching to produce a different type of product, the weight must be rotated 180 degrees to replace the forming structures at its bottom.

[0003] Currently, the main method for achieving a 180-degree tilt of a counterweight is to wrap a steel wire rope around it and use an overhead crane to complete the tilting operation. However, due to the considerable weight of the counterweight, this traditional tilting method is not only complex to operate but also poses significant safety risks. Specifically, improper operation may lead to the counterweight going out of control, causing serious consequences such as equipment damage or personal injury. To improve production efficiency and operational safety, those skilled in the art urgently need to design a device specifically for tilting a counterweight 180 degrees. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a 180° flipping device for a weight.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] A 180° tilting device for a weight includes a base, a lifting device, a support platform, and a collar; the support platform is provided above the base, and the support platform has legs on both sides that can be placed on the ground; a lifting device for lifting the support platform is provided between the top of the base and the bottom of the support platform; a collar is rotatably connected to the top of the support platform, and the end face of the collar has a cavity that corresponds to and is adapted to the weight.

[0007] Preferably, the support platform is provided with support rollers at each of the four corners of the top for rolling the support ring.

[0008] Preferably, the outer circumference of the collar is provided with an annular limiting boss.

[0009] Preferably, the bottom of both ends of the support platform is provided with guide columns that can be moved through the top of the lifting device.

[0010] Preferably, casters are provided at all four corners of the base.

[0011] Preferably, the lifting device is a scissor lift platform.

[0012] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0013] This utility model discloses a 180° tilting device for a counterweight. It has a simple structure, is easy to assemble, and the tilting operation is stable and safe. In use, the overhead crane is controlled to insert both ends of the counterweight into the cavities of the corresponding collars. First, the lifting platform of the lifting device is controlled to descend until the outriggers touch the ground. Then, the overhead crane is controlled to lower the counterweight, which drives the collars to fall onto the support rollers. The outriggers support the counterweight, ensuring high safety and stability and preventing the counterweight from directly pressing on the lifting device, which could damage the lifting device.

[0014] This utility model further provides an annular limiting boss on the outer circle of the ring. The annular limiting boss is located between the support rollers on both sides of the support platform, which can prevent the ring from moving along its own axis during rotation, causing the ring to accidentally detach from the support platform.

[0015] This utility model further provides casters at the four corners of the base. In use, the hammer is lifted and suspended in the air by a crane. The casters cause the base to move the collar to the corresponding end of the hammer. After the cavity is aligned with the corresponding end face of the hammer, the casters cause the base to move the collar until the collar is fitted onto the corresponding end of the hammer. The operation is convenient and quick. There is no need to operate the crane when the collar is engaged with the corresponding end of the hammer, which reduces the difficulty of operation.

[0019] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0020] Example 1, in conjunction with Appendix Figures 1-2A 180° tilting device for a weight includes a base 1, a lifting device 2, a support platform 3, and a collar 4. The support platform 3 is located above the base 1, and has legs 5 on both sides that can touch the ground. These legs support the platform 3 during the tilting of the weight. The legs 5 are equipped with foot pads to stably support the platform 3. The lifting device 2, which adjusts the height of the platform 3, is located between the top of the base 1 and the bottom of the support platform 3. The lifting device 2 can be a scissor lift for smooth lifting. The platform 3 and the lifting surface of the lifting device 2 can be separated. A collar 4 is rotatably connected to the top of the support platform 3. The end face of the collar 4 has a cavity 6 that corresponds to and fits the weight, allowing the end of the weight to be inserted into the cavity 6. If necessary, support rollers 7 are provided at the four corners of the top of the support platform 3 to roll the support collar 4, thus the collar 4 is rotatably connected to the support platform 3 via the support rollers 7.

[0021] The 180° tilting device for the hammer in this embodiment is used in pairs. During use, the hammer is suspended in the air by an overhead crane. Bases 1 are placed at both ends of the hammer. The support platform 3 is raised by the lifting device 2, which in turn raises the collar 4 until the cavity 6 is aligned with the corresponding end face of the hammer. The overhead crane is then controlled to insert both ends of the hammer into the cavity 6 of the corresponding collar 4. First, the lifting platform of the lifting device 2 is lowered until the support leg 5 touches the ground. Then, the overhead crane is controlled to lower the hammer, which pulls the collar 4 onto the support roller 7. The support leg 5 supports the hammer, ensuring high safety and stability and preventing the hammer from directly pressing on the lifting device 2 and damaging it. Then, with the assistance of the overhead crane, the hammer can be tilted 180° along the axis of the collar 4 to facilitate the replacement of the molded structural components at the bottom of the hammer.

[0022] Example 2, in conjunction with Appendix Figures 1-2 A 180° flipping device for a counterweight differs from Embodiment 1 in that, based on Embodiment 1, the outer circumference of the collar 4 is provided with an annular limiting boss 8, which is located between the support rollers 7 on both sides of the support platform 3. This can prevent the collar 4 from moving along its own axis during rotation, thus preventing the collar 4 from accidentally detaching from the support platform 3.

[0023] Both ends of the support platform 3 are equipped with guide columns 9 that can be moved through the top of the lifting device 2. That is, after the support leg 5 lands, it can control the lifting platform of the lifting device 2 to continue to descend, ensuring that the support platform 3 and the lifting platform of the lifting device 2 are separated. The guide columns 9 can prevent accidental misalignment after the support platform 3 and the lifting platform of the lifting device 2 are separated.

[0024] Example 3, in conjunction with the appendix Figures 1-2A 180° tilting device for a counterweight, based on embodiment 1 or 2, has casters 10 at each of the four corners of the base 1. In use, the counterweight is suspended by a crane, and the casters 10 move the base 1, along with the collar 4, to the corresponding end of the counterweight. The lifting device 2 then raises the support platform 3, further lifting the collar 4 until the cavity 6 is aligned with the corresponding end face of the counterweight. The casters 10 then move the base 1, along with the collar 4, until the collar 4 is fitted onto the corresponding end of the counterweight. The operation is convenient and quick; the crane is not required when the collar 4 is engaged with the corresponding end of the counterweight, reducing operational difficulty. The lifting platform of the lifting device 2 is lowered until the support leg 5 lands on the ground. Then, the crane is controlled to make the counterweight and collar 4 fall onto the support rollers 7, allowing the counterweight to tilt 180° along the axis of the collar 4 with the assistance of the crane.

[0025] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
