Description

Technical Field

[0001] The present invention relates to the technical field of isostatic graphite processing, and specifically to an anti-falling device for hoisting isostatic graphite. Background Art

[0002] As a new type of graphite material with excellent properties, isostatic graphite plays a crucial role in the modern industrial field. It has characteristics such as high density, high purity, good isotropy, and good high-temperature resistance, corrosion resistance, and electrical conductivity, and is widely used in many key industries such as metallurgy, chemical industry, electronics, and aerospace; during the production and processing of isostatic graphite, it is necessary to frequently hoist graphite raw materials, semi-finished products, and finished products.

[0003] In traditional isostatic graphite hoisting, simple fixtures are often used for hoisting. These fixtures are usually made of metal and fix isostatic graphite by mechanical clamping. For example, using pliers to directly clamp the edge of the graphite, or using a clamp to hoop the graphite tightly.

[0004] The traditional fixture hoisting method can only be applied to isostatic graphite with specific sizes and shapes. For diversified graphite products, it is necessary to frequently replace the fixtures, increasing production costs and hoisting time. At the same time, during hoisting, it is only fixed by friction, and when encountering bumps, vibrations, etc. during hoisting, it is extremely easy to fall off, causing damage to the graphite and even triggering safety accidents. Summary of the Invention

[0005] The purpose of this application is to provide an anti-falling device for hoisting isostatic graphite, which solves the problem that the traditional fixture hoisting method can only be applied to isostatic graphite with specific sizes and shapes, improves the adaptability range of the device, and at the same time improves the stability of the graphite during hoisting.

[0006] To achieve the above purpose, this application provides an anti-falling device for hoisting isostatic graphite, including a support platform and an anti-falling mechanism. Four adjustment grooves are opened at the top of the support platform, and lead screws are arranged in the adjustment grooves; on one side of the lead screw close to the center of the support platform, there is a first bevel gear, and a motor is arranged at the bottom of the support platform. The output end of the motor is connected with a second bevel gear, and the first bevel gear meshes with the second bevel gear; the anti-falling mechanism includes a first limiting plate and a second limiting plate. The first limiting plate is arranged on the left and right sides of the support platform and is connected with the lead screw. The second limiting plate is arranged on the front and back sides of the support platform and is connected with the lead screw. Elastic telescopic mechanisms are arranged on both sides of the second limiting plate and are in contact with the first limiting plate. The space between the first limiting plate and the second limiting plate is used to place isostatic graphite.

[0007] As a further solution of the present invention: The elastic telescopic mechanism includes an elastic plate and a first spring. Telescopic grooves are formed on the side walls on both sides of the second limiting plate. The elastic plate is arranged in the telescopic grooves. One end of the first spring is connected to the bottom of the telescopic groove, and the other end is connected to the elastic plate. The elastic plate abuts against the side wall of the first limiting plate.

[0008] As a further solution of the present invention: A guide groove is arranged on the side of the first limiting plate close to the elastic plate. A guide block is arranged on the outer side wall of the elastic plate. The guide block is in sliding fit with the guide groove.

[0009] As a further solution of the present invention: A first slider is arranged at the bottom of the first limiting plate. The first slider is threadedly connected to the lead screw. A second slider is arranged at the bottom of the second limiting plate. The second slider is threadedly connected to the lead screw.

[0010] As a further solution of the present invention: Columns are arranged at the corners of the top of the support platform. An installation frame is fixedly arranged at the top of the columns. Hook grooves are arranged on the inner side wall of the installation frame.

[0011] As a further solution of the present invention: Four hook grooves are arranged.

[0012] As a further solution of the present invention: A second spring is arranged between the first slider, the second slider and the side wall of the adjustment groove. The second spring is sleeved on the lead screw and is arranged on the side away from the isostatic graphite.

[0013] As a further solution of the present invention: Support legs are arranged at the bottom of the support platform.

[0014] As a further solution of the present invention: The sizes of the first slider and the second slider are adapted to the adjustment groove.

[0015] As a further solution of the present invention: Buffer pads are arranged at the bottoms of the support legs.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the motor drives the second bevel gear to drive the first bevel gear to rotate, so as to realize the rotation of the lead screw, drive the first limiting plates on the left and right sides to approach the center of the support platform, and at the same time, the second limiting plates on the front and back sides also approach the support platform, so as to limit the graphite arranged between the first limiting plate and the second limiting plate. When the first limiting plate approaches, in order not to interfere with the second limiting plate, the elastic telescopic mechanism arranged on both sides of the second limiting plate can contract when the first limiting plate moves, can adapt to isostatic graphite of various size specifications, does not need to frequently replace the lifting equipment, and improves the equipment utilization rate.

[0018] 2. When the first limiting plate moves towards the center of the support platform in the present invention, the elastic plate is squeezed, compressing the first spring and moving into the telescopic groove; this avoids interference between the first limiting plate and the second limiting plate when they move towards the center of the support platform, and at the same time can adaptively adjust the clamping force according to the shape and size of the graphite, enhancing the anti-dropping performance.

[0019] 3. In the initial state of the present invention, the second spring is in a compressed state. When the first limiting plate and the second limiting plate move towards the center of the support platform, the elastic force released by the second spring supports the first limiting plate and the second limiting plate, and can buffer vibrations during the lifting process, improving the stability of the isostatic graphite lifting.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0029] As Figures 1 to 6 shown, an isostatic graphite lifting device for preventing shedding includes a support platform 1 and an anti-shedding mechanism. Four adjustment grooves 11 are provided at the top of the support platform 1, and a lead screw 12 is arranged in the adjustment groove 11; a first bevel gear 13 is arranged on one side of the lead screw 12 close to the center of the support platform 1, and a motor 2 is arranged at the bottom of the support platform 1. The output end of the motor 2 is connected to a second bevel gear 21, and the first bevel gear 13 meshes with the second bevel gear 21; the anti-shedding mechanism includes a first limiting plate 3 and a second limiting plate 4. The first limiting plate 3 is arranged on the left and right sides of the support platform 1 and is connected to the lead screw 12. The second limiting plate 4 is arranged on the front and back sides of the support platform 1 and is connected to the lead screw 12. Elastic telescopic mechanisms are arranged on both sides of the second limiting plate 4, and the elastic telescopic mechanisms are in contact with the first limiting plate 3. The space between the first limiting plate 3 and the second limiting plate 4 is used to place isostatic graphite.

[0030] The motor 2 drives the second bevel gear 21 to drive the first bevel gear 13 to rotate, realizing the rotation of the lead screw 12, driving the first limiting plates 3 on the left and right sides to approach the center of the support platform 1, and at the same time, the second limiting plates 4 on the front and back sides also approach the support platform 1 to limit the graphite arranged between the first limiting plate 3 and the second limiting plate 4. When the first limiting plate 3 approaches, in order not to interfere with the second limiting plate 4, the elastic telescopic mechanisms arranged on both sides of the second limiting plate 4 can contract when the first limiting plate 3 moves, and can adapt to isostatic graphite of various size specifications, without the need to frequently replace the lifting equipment, improving the equipment utilization rate.

[0031] The elastic telescopic mechanism includes an elastic plate 44 and a first spring 43. Telescopic grooves 42 are provided on the side walls on both sides of the second limiting plate 4. The elastic plate 44 is arranged in the telescopic grooves 42. One end of the first spring 43 is connected to the bottom of the telescopic groove 42, and the other end is connected to the elastic plate 44. The elastic plate 44 is in contact with the side wall of the first limiting plate 3.

[0032] When the first limiting plate 3 moves towards the center of the support table 1, the elastic plate 44 is squeezed, compressing the first spring 43 and moving into the telescopic groove 42; this avoids interference between the first limiting plate 3 and the second limiting plate 4 when they move towards the center of the support table 1, and at the same time can adaptively adjust the clamping force according to the shape and size of the graphite, enhancing the anti-dropping performance.

[0033] A guide groove 32 is provided on one side of the first limiting plate 3 close to the elastic plate 44, and a guide block 441 is provided on the outer side wall of the elastic plate 44. The guide block 441 is slidably engaged with the guide groove 32. By setting the sliding fit between the guide block 441 and the guide groove 32, it provides a guiding effect when the second limiting plate 4 moves towards the center of the support table 1, and at the same time reduces the friction between the elastic plate 44 and the first limiting plate 3, reducing wear during movement, ensuring the stability and accuracy of the telescopic movement of the elastic plate 44, preventing the elastic plate 44 from shifting or jamming, and improving the reliability of the elastic telescopic mechanism.

[0034] A first slider 31 is provided at the bottom of the first limiting plate 3, and the first slider 31 is threadedly connected to the lead screw 12. A second slider 41 is provided at the bottom of the second limiting plate 4, and the second slider 41 is threadedly connected to the lead screw 12. When the lead screw 12 rotates, the first slider 31 and the second slider 41 move along the axial direction of the lead screw 12 due to the threaded connection, driving the first limiting plate 3 and the second limiting plate 4 to move, and can quickly adapt to isostatic graphite of different sizes, improving the adaptation range of the equipment.

[0035] Columns 5 are provided at the top corners of the support table 1. An installation frame 51 is fixedly provided at the top of the column 5, and a hook groove 52 is provided on the inner side wall of the installation frame 51.

[0036] The column 5 supports the installation frame 51. The hook groove 52 on the inner side wall of the installation frame 51 is used to hang the hook of the lifting equipment, realizing the connection between the lifting device and the lifting equipment, providing a structure for the connection between the lifting device and the lifting equipment, facilitating the lifting operation, and at the same time enhancing the overall stability of the device.

[0037] Four hook grooves 52 are provided. The four hook grooves 52 are evenly distributed on the inner side wall of the installation frame 51. During lifting, multiple hooks can be simultaneously hung, making the lifting force more uniform; improving the stability of lifting, avoiding tilting or shaking of the lifting device due to uneven force, and ensuring the safety of lifting.

[0038] A second spring 6 is arranged between the first slider 31, the second slider 41 and the side wall of the adjustment groove 11. The second spring 6 is sleeved on the lead screw 12 and arranged on the side away from the isostatic graphite. In the initial state, the second spring 6 is in a compressed state. When the first limiting plate 3 and the second limiting plate 4 move towards the center of the support platform 1, the elastic force released by the second spring 6 supports the first limiting plate 3 and the second limiting plate 4, and can buffer vibrations during the lifting process, improving the stability of the isostatic graphite during lifting.

[0039] Support legs 7 are arranged at the bottom of the support platform 1 to bear the weight of the lifting device and the isostatic graphite, disperse it to the ground, ensure the stability of the lifting device during placement and lifting, prevent the device from tipping over, guarantee operation safety, and at the same time directly avoid the motor 2 from contacting the ground.

[0040] The sizes of the first slider 31 and the second slider 41 are adapted to the adjustment groove 11, improving the stability of the position adjustment of the first limiting plate 3 and the second limiting plate 4.

[0041] Buffer pads are arranged at the bottoms of the support legs 7 to ensure the stability of the lifting device during placement and lifting and reduce vibrations.

[0042] The working principle of the present invention: Before lifting the isostatic graphite, first place the device in a suitable position, and the support legs 7 bear the weight of the entire device. Start the motor 2, and the output shaft of the motor 2 drives the second bevel gear 21 to rotate clockwise or counterclockwise. Since the second bevel gear 21 meshes with the first bevel gear 13, the rotation of the second bevel gear 21 will cause the first bevel gear 13 to rotate in the same direction. The first bevel gear 13 is fixed on the side of the lead screw 12 close to the center of the support platform 1, so the lead screw 12 also starts to rotate accordingly. When the lead screw 12 rotates, the first slider 31 at the bottom of the first limiting plate 3 and the second slider 41 at the bottom of the second limiting plate 4 will move linearly along the adjustment groove 11 under the drive of the lead screw 12. During this process, the first limiting plates 3 on the left and right sides will approach the center of the support platform 1, and the second limiting plates 4 on the front and rear sides will also approach the center of the support platform 1 synchronously.

[0043] When the first limiting plate 3 gradually approaches the second limiting plate 4, the elastic telescopic mechanisms on both sides of the second limiting plate 4 start to play a role. The elastic telescopic mechanism consists of an elastic plate 44 and a first spring 43. Telescopic grooves 42 are formed on the side walls of both sides of the second limiting plate 4, the elastic plate 44 is installed in the telescopic groove 42, one end of the first spring 43 is connected to the bottom of the telescopic groove 42, and the other end is connected to the elastic plate 44. As the first limiting plate 3 approaches, the elastic plate 44 is squeezed, starts to compress the first spring 43, and contracts into the telescopic groove 42, thus avoiding interference between the first limiting plate 3 and the second limiting plate 4 during the approaching process.

[0044] When the first limiting plate 3 and the second limiting plate 4 move to appropriate positions and firmly clamp the isostatic graphite in the middle, the hoisting preparation work is completed. At this time, the isostatic graphite is firmly fixed and is not likely to be displaced or fall off even in the event of vibrations during hoisting. If hoisting is required, the hook can be hung on the hook groove 52 on the inner side wall of the mounting frame 51 and connected to the hoisting equipment, and the hoisting operation can be completed by starting the hoisting equipment. After the hoisting is completed, the motor 2 rotates in reverse, and the first limiting plate 3 and the second limiting plate 4 move in the reverse direction driven by the lead screw 12. The elastic plate 44 extends out of the telescopic groove 42 under the elastic force of the first spring 43 and returns to the initial position, facilitating the removal of the isostatic graphite.

[0045] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
