Description

Technical Field

[0001] This utility model relates to the technical field of graphite block flipping equipment, and in particular to a convenient flipping fixture for large-sized graphite blocks. Background Technology

[0002] Graphite blocks are typically made from petroleum coke or pitch coke as the main raw material, supplemented with coal tar pitch as a binder. The main steps include: calcination, crushing and screening, batching, mixing and kneading, molding, roasting, graphitization, and machining.

[0003] In the process of calcination, graphitization, or finished product transfer, it is often necessary to change the orientation of the graphite blocks. For example, after calcination, large graphite blocks are often flipped to separate the filler and the calcined product. During graphitization, resistive materials (such as coke particles) are added to cover the workpiece. After processing, flipping is used to efficiently separate the resistive material from the finished graphite blocks. Sometimes, graphite blocks also need to be flipped before being transferred using other tools. Therefore, flipping equipment is indispensable in the process of graphite block processing.

[0004] For example, in Chinese invention patent application number 202210464209.8, entitled "Automatic Flipping Device and Automatic Flipping Method for Large Graphite Blanks", there is one such flipping device. However, in that patent, it can only flip graphite blocks in a specific state and cannot adapt well to flipping in other states. Therefore, this application proposes a convenient flipping fixture for large-size graphite blocks to achieve multi-directional flipping of graphite blocks. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology has a relatively single flipping direction for graphite blocks, and to propose a convenient flipping tool for large-sized graphite blocks.

[0021] 1. This utility model, through the setting of a flipping mechanism, can flip the graphite block in one direction, while the setting of a turntable mechanism can flip the graphite block in another different direction, thereby achieving the effect of multi-directional flipping of the graphite block, improving the ease of use of the device, and thus solving the problem of the relatively single flipping direction of the graphite block in the prior art.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figures 1-8 A convenient flipping fixture for large-sized graphite blocks includes a support frame 1, and also includes:

[0037] A clamping mechanism used to clamp and limit the graphite block;

[0038] A flipping mechanism, used to flip the graphite block;

[0039] A turntable mechanism is used to flip the graphite block, and its flipping direction is different from that of the flipping mechanism;

[0040] Both the clamping mechanism and the turntable mechanism are mounted on the flipping mechanism;

[0041] The position of the support frame 1 corresponds to the clamping mechanism.

[0042] In a specific embodiment of this utility model, the clamping mechanism is mainly used to clamp and limit the graphite block. Specifically, during the flipping process of the graphite block, it can maintain the stability of the graphite block and prevent it from bumping or colliding. The flipping mechanism is used to flip the graphite block, specifically, for example, to flip a flat rectangular graphite block from a horizontally placed state (see attached figure). Figure 7 Flip it ninety degrees to make it stand up (see appendix) Figure 8 The turntable mechanism is also used to flip the graphite block, but the direction of flipping is different from that of the flipping mechanism, as shown in the attached diagram. Figure 7 The cuboid graphite block shown is initially placed horizontally. To flip it over so that it remains horizontal after being flipped, the graphite block can first be stood up using a flipping mechanism. Then, the turntable mechanism can be rotated at a certain angle, such as 180 degrees, and then the flipping mechanism can be used again to place it horizontally. This completes the flipping action of the graphite block, meaning that the side of the graphite block that was originally facing up becomes facing down after being flipped. The support frame 1 can be used to temporarily support the graphite block.

[0043] The flipping mechanism includes a base frame 16, a flipping bracket 11, and a flipping hydraulic rod 3. One end of the flipping bracket 11 is hinged to the upper middle position of the base frame 16. One end of the flipping hydraulic rod 3 is hinged to the lower middle position of the flipping bracket 11, and the other end is hinged to the bottom of the base frame 16.

[0044] During use, the flipping mechanism uses the flipping hydraulic rod 3 to lift the flipping bracket 11. Since the flipping bracket 11 and the base frame 16 are hinged, the flipping bracket 11 can rotate around the hinge axis, which in turn drives the clamping mechanism and the turntable mechanism to rotate as well, thereby achieving the effect of flipping the graphite block.

[0045] The clamping mechanism includes a clamp bracket 7, a clamping hydraulic rod 10, an upper clamping plate 9, and a lower clamping plate 4. The clamp bracket 7 is mounted on the clamp bracket 7 via an adjustment mechanism. The lower clamping plate 4 is fixedly located at the lower end of the clamp bracket 7. The clamping hydraulic rod 10 is fixedly located at the top end of the clamp bracket 7, with the telescopic rod of the clamping hydraulic rod 10 pointing downwards. The upper clamping plate 9 is fixedly located at the end of the telescopic rod of the clamping hydraulic rod 10. To prevent relative rotation between the upper clamping plate 9 and the clamp bracket 7, a limiting slide rod can be provided. That is, the limiting slide rod is slidably located on the upper part of the clamp bracket 7, and one end of the limiting slide rod is fixedly connected to the upper clamping plate 9 to limit the movement of the lower clamping plate 4 without affecting the movement of the upper clamping plate 9.

[0046] During use, the clamping mechanism uses the clamping hydraulic rod 10 to move the upper clamping plate 9, allowing the upper clamping plate 9 to move closer to or further away from the lower clamping plate 4, thereby achieving the effect of clamping and releasing, and realizing the clamping limit or release limit of the graphite block.

[0047] The adjustment mechanism includes a guide rail 8, a slider 18, and an adjusting hydraulic rod 19. The guide rail 8 is fixedly installed in front of the flipping bracket 11 and away from the hinge position between the flipping bracket 11 and the base frame 16. The slider 18 is fixedly installed on the back of the clamp bracket 7 and slides inside the guide rail 8. The top end of the adjusting hydraulic rod 19 is fixedly connected to the bottom surface of the lower clamping plate 4, and the bottom end is fixedly connected to the bottom of the guide rail 8.

[0048] When in use, the adjusting mechanism can drive the entire clamping mechanism to move by adjusting the hydraulic rod 19, and the movement path is restricted by the slider 18 and the guide rail 8. Therefore, the clamping mechanism can reciprocate linearly along a specific path. At the same time, the main purpose of setting the adjusting mechanism is to allow the lower clamping plate 4 to move so that it can be higher or lower than the conveying mechanism 2.

[0049] A positioning mechanism is provided on the side of the fixture bracket 7. The positioning mechanism includes a positioning hydraulic rod 6 and a positioning plate 5. The positioning hydraulic rod 6 is fixedly installed on the side of the fixture bracket 7, and the telescopic rod of the positioning hydraulic rod 6 faces forward. The positioning plate 5 is fixedly installed at the end of the telescopic rod of the positioning hydraulic rod 6.

[0050] When in use, the positioning mechanism uses the positioning hydraulic rod 6 to move the positioning plate 5 so that the graphite block can stop at the preset position.

[0051] The turntable mechanism includes a mounting plate 12, a bearing hydraulic rod 13, and a base 15. The mounting plate 12 is fixedly installed in front of the flipping bracket 11 and near the hinge position between the flipping bracket 11 and the base frame 16. The bearing hydraulic rod 13 is fixedly installed on the mounting plate 12, and the base 15 is fixedly installed at the end of the telescopic rod of the bearing hydraulic rod 13. To prevent relative rotation between the base 15 and the mounting plate 12, a limiting slide rod can be provided. That is, the limiting slide rod at this location is slidably connected to the mounting plate 12, and a section of the limiting slide rod is fixedly connected to the base 15, thereby preventing relative rotation between the base 15 and the mounting plate 12 without affecting the normal movement of the base 15. The bearing hydraulic rod 13 can drive the base 15 to move, thereby enabling the turntable 14 to contact or move away from the graphite block.

[0052] The turntable mechanism also includes a turntable 14 and a drive structure 17. The turntable 14 is rotatably mounted on one side of the base 15 and close to the support frame 1. The drive structure 17 is mounted on the other side of the base 15 and is used to drive the turntable 14 to rotate. The drive structure 17 can adopt a conventional drive rotation method, such as using a motor and a reducer. The rotation of the motor is used to drive the rotation of the turntable 14. Specifically, the motor and the reducer are fixed on the side of the base 15 away from the turntable 14. Then, the input end of the reducer is connected to the output end of the motor, and the shaft of the output end of the reducer is connected to the turntable 14, thereby achieving the effect of the motor driving the turntable 14 to rotate.

[0053] When using the turntable mechanism, it is necessary to ensure that the turntable 14 is placed horizontally, that is, the turntable 14 is used to support the graphite block (see appendix). Figure 8 (However, the clamping mechanism does not clamp it). When in this state, the drive structure 17 slowly drives the turntable 14 to rotate, causing the graphite block to rotate slowly as well, thereby changing the placement state of the graphite block.

[0054] The support frame 1 is equipped with a conveying mechanism 2, which is used to send the graphite block to the clamping mechanism. The conveying mechanism 2 can be a conventional equipment in the field, such as a conveyor belt or a chain conveyor belt. Its main function is to send the graphite block to the position of the clamping mechanism.

[0055] Workflow: Scenario 1: If the horizontal graphite block is to be stood upright, first adjust this device to be attached... Figure 1The state shown is that the lower clamping plate 4 is lower than the conveying mechanism 2, and the upper clamping plate 9 is moved away from the lower clamping plate 4. The position of the positioning plate 5 is adjusted according to the size of the graphite block (the adjustment logic is that after blocking the graphite block, the end of the graphite block can be located within the circular range of the turntable 14). Then, using a forklift or other handling method, the graphite block is placed on the conveying mechanism 2. The conveying mechanism 2 then sends the graphite block between the upper clamping plate 9 and the lower clamping plate 4. When the graphite block reaches the positioning plate 5, the adjusting mechanism drives the clamping mechanism to move upward, so that the lower clamping plate 4 contacts the bottom surface of the graphite block. Then, the clamping hydraulic rod 10 drives the upper clamping plate 9 to move downward, clamping the graphite block. Then, the bearing hydraulic rod 13 drives the base 15 to move, which in turn moves the turntable 14, so that the turntable 14 contacts the side of the graphite block. Then, the flipping mechanism is activated to flip the block. The state after the flipping is completed is shown in the appendix. Figure 8 Then, the adjusting mechanism and the clamping hydraulic rod 10 are used to drive the lower clamping plate 4 and the upper clamping plate 9 away from the graphite block, and then the next process is carried out.

[0056] Scenario 2: If the horizontal graphite block is to be flipped over, first follow the steps in Scenario 1. Stand the graphite block upright, then release the clamping mechanism. Move the positioning plate 5 backward to avoid affecting the rotation of the graphite block. Then, use the drive structure 17 to drive the turntable 14 to rotate slowly, which in turn drives the graphite block to rotate slowly. Select the rotation angle as needed. After the rotation is completed, the clamping mechanism clamps the graphite block. Then, use the flipping mechanism to flip it back so that the graphite block is placed horizontally again. Then, release the clamping mechanism to complete the flipping.

[0057] Scenario 3: If the graphite block is to be laid flat, first use the flipping mechanism to adjust the turntable 14 to a horizontal position, and move the positioning plate 5 backward. Then, open the clamping mechanism and use equipment such as an overhead crane to hoist the graphite block onto the turntable 14. Then, use the turntable 14 to adjust the angle of the graphite block, and then use the clamping mechanism to clamp the graphite block. See the appendix for the state at this time. Figure 8 Then, the graphite block is flattened using a flipping mechanism, and then unloaded using a forklift or other handling equipment to complete the flipping.
