Abstract
Description
Technical Field
[0001] The utility model particularly relates to a maglev centrifuge for a concrete pole mold. Background Art
[0002] Concrete poles need to be formed by centrifugation. The centrifugation process requires the use of a pole mold, which includes an upper mold and a lower mold. During centrifugation, the upper mold and the lower mold are fixedly connected together by clamping bolts. During centrifugation, the centrifuge drives the pole mold to rotate from slow to fast. Due to the action of centrifugal force, the concrete in the steel mold bonds with the steel bars after a certain time and tightly adheres to the inner wall of the steel mold, and becomes a cement pole after densification and curing. After centrifugation, it is necessary to remove the clamping bolts to separate the upper mold and the lower mold to take out the pole. In the use process of some existing concrete pole centrifuges, the mold is prone to large vibrations on the centrifuge under the action of centrifugal force, resulting in uneven stress of the concrete in the mold and easy generation of defective products, affecting normal use.

One side of the connecting frame is fixed to the arc-shaped clamping member. A fixed column is arranged on the bracket, and a spring is wound around the fixed column.

[0021] A magnetic levitation centrifuge for a concrete pole mold, referring to Figure 1 - Figure 2 , includes a workbench 1 and a machine body 2 arranged on the workbench 1. A pole mold 3 is drivingly connected to the machine body 2. Buffer boxes 4 are respectively arranged on both sides of the pole mold 3. Each buffer box 4 is provided with an opening 41. The two openings 41 enclose a through hole for the pole mold 3 to pass through. A bracket 5 is arranged in each buffer box 4. An arc-shaped clamping member 6 is arranged on the bracket 5. A buffer mechanism is arranged between the bracket 5 and the arc-shaped clamping member 6. A roller 7 that is in rolling cooperation with the pole mold 3 is arranged on each arc-shaped clamping member 6. The arc-shaped clamping member 6 plays a shock-absorbing effect on the pole mold 3 under the action of the buffer mechanism.
[0022] Further, the buffer mechanism includes a connecting frame 8 arranged between the arc-shaped clamping member 6 and the bracket 5. One side of the connecting frame 8 is fixed on the arc-shaped clamping member 6. A fixed column 9 is arranged on the bracket 5. A spring 10 is wound around the fixed column 9. One end of the spring 10 is connected to the connecting frame 8. At least two or more guide rods 11 are arranged on the bracket 5. The guide rods 11 are jointly movably connected to the connecting frame 8.
[0023] Further, it also includes a threaded rod 12. A swing arm 13 is rotatably connected to each bracket 5. A threaded sleeve 14 is opened on each swing arm 13. The two threaded sleeves 14 jointly connect the threaded rod 12.
[0024] Further, an operation port 15 is opened on the top end of each buffer box 4. After the two buffer boxes 4 are installed on the workbench 1, the upper end of the threaded rod 12 can extend out from the operation port 15.
[0025] Further, the machine body 2 is a magnetic levitation centrifuge.
[0026] Further, a fixing block 16 for connecting the buffer box 4 is arranged at the lower end of the bracket 5.
[0027] The working principle of the utility model is:
[0028] After the assembly, the buffer box 4 is as follows Figure 1 As shown by Figure 1 It can be seen that the pole mold 3 passes through the through hole surrounded by the two openings 41 of the buffer box 4. Since the structural coordination of the present application is mainly to play a shock-absorbing role for the pole mold 3, this part will be described in detail. The working principle of the pole mold 3 in the centrifugal equipment belongs to the conventional means in this technical field, so it will not be repeated in this article.
[0029] After the pole mold 3 passes through the through hole, the arc-shaped clamping parts 6 are respectively clamped on both sides of the pole mold 3 to form a hugging state. When the pole mold 3 vibrates greatly, the arc-shaped clamping parts 6 will first be subjected to the force of the vibration. According to the force transmission effect, the arc-shaped clamping parts 6 will push the connecting frame 8 to move away from the pole mold 3. A fixing column 9 is arranged between the pole mold 3 and the bracket 5. The fixing column 9 is arranged on the bracket 5. A spring 10 is wound on the fixing column 9. One end of the spring 10 is connected to the connecting frame 8. When the pole mold 3 vibrates, the force will be transmitted. To the arc-shaped clamping member 6, the arc-shaped clamping member 6 will drive the connecting frame 8 to squeeze the spring 10. According to the principle of force action, the spring 10 will automatically restore the deformation after being squeezed, that is, the spring 10 will push the connecting frame 8 to move along the original direction, and finally drive the arc-shaped clamping member 6 to move, which has a pressing effect on the pole mold 3, and can minimize the vibration generated by the mold, thereby solving the problem that the existing pole mold 3 is prone to large-scale vibration on the centrifuge under the action of centrifugal force, and avoiding the problem that the concrete in the pole mold 3 is unevenly stressed and easily produces defective products, affecting normal use. In the above technology, since the pole mold 3 is connected through the body 2 during operation, the present application is provided with a roller 7 on the arc-shaped clamping member 6, and the setting of the roller 7 can better achieve rolling cooperation with the pole mold 3.
[0030] In the above technology, in order to make the arc-shaped clamping member 6 better press the pole mold 3, the movement trajectory of the arc-shaped clamping member 6 is particularly important. In this application, two guide rods 11 are arranged on the bracket 5. When the connecting frame 8 is in the process of moving, the guide rods 11 will pass through the connecting frame 8. The setting of the guide rods 11 has a guiding effect on the movement trajectory of the connecting frame 8, so the relative position of the arc-shaped clamping member 6 and the pole mold 3 can be limited.
[0031] In the above technology, in order to enhance the connection stability between the two buffer boxes 4, in this application, a swing arm 13 is rotatably arranged on each bracket 5, and a threaded sleeve 14 is arranged on each swing arm 13. The two threaded sleeves 14 are jointly connected to the threaded rod 12; thus, the connection stability between the two brackets 5 is enhanced, and the operation port 15 is provided to facilitate the installation of the threaded rod 12 by the staff. In addition, a fixing block 16 is provided at the lower end of the bracket 5, and the fixing block 16 can be fixed in the buffer box 4 by bolts. In the technical solution of this application, since the rollers 7 on the arc-shaped clamping member 6 need to be in rolling cooperation with the pole mold 3 during operation, that is to say, the installation positions of the two buffer boxes 4 are particularly important. As Figure 1 shown, the two buffer boxes 4 are respectively fixed on both sides of the pole mold 3. After determining the positions, the buffer boxes 4 can be fixed on the workbench 1 by bolts.
[0032] In the above technical solution, regarding the selection of the machine body 2, a magnetic levitation centrifuge can be used to drive the pole mold 3, or a driving pulley can be arranged through a motor, and the pole mold 3 is drivingly connected to the outer surface of the driving pulley. Since this part belongs to a mature design principle and is not the design concept of this application, it will not be elaborated here.
