[0001] The utility model relates to the field of concrete casting molds, in particular to a concrete support rail casting mold for a maglev train. Background Technique

[0002] The vacuum tube maglev train, whose principle is to utilize the vacuum tube and superconducting maglev technology to achieve high-speed "near-earth flight", is known as the "fifth mode of transportation" for mankind after roads, railways, waterways and aviation. Since this kind of train needs to run in a relatively airtight vacuum tube, the requirements for its various components are relatively strict. Generally, concrete precast components are used during track laying to enhance the strength of the track.

[0003] Existing concrete components generally use casting molds. After casting and waiting for the concrete to solidify, they can be taken out for use, thus enhancing the strength of the track during use. However, after pouring the concrete into the mold, the top surface is uneven and usually needs to be manually leveled. This method not only has low efficiency, but also has a high labor intensity for workers. At the same time, there will be air bubbles in the concrete, which affects the overall strength of the concrete component. In view of the above problems, the technical personnel in this field have proposed a concrete support rail casting mold for a maglev train to solve the above problems. Content of the Utility Model

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a concrete support rail casting mold for a maglev train, comprising a mold body 1, a limited position frame 2 is fixedly connected to the top left side of the mold body 1, a rack plate 3 is fixedly connected to the inside of the limited frame 2, a support frame 4 is slidably connected to the inside of the limited frame 2, a motor 5 is installed on the outer left side of the support frame 4, a gear 6 is fixedly connected to the output end of the motor 5, a scraper plate 11 is fixedly connected to the inner opposite surface of the support frame 4, a vibration component is arranged on the top of the support frame 4, and the vibration component is used to vibrate the concrete, a fixed seat 12 is fixedly connected to the top right side of the mold body 1, a slide bar 7 is fixedly connected between the inner opposite surfaces of the fixed seat 12, an ejection component is arranged inside the mold body 1, and the ejection component is used to push the concrete out of the mold body 1, the outer side of the gear 6 is meshedly connected to the outer side of the rack plate 3, the gear 6 is rotatably connected to the inside of the support frame 4, and the outer side of the slide bar 7 is slidably connected to the other end of the support frame 4.

[0023] Specifically, the limiting frame 2 is fixed by the mold body 1, so that the limiting frame 2 can fix the rack plate 3. Then, after starting the first motor 5, the first motor 5 drives the gear 6 to rotate. Since the gear 6 and the rack plate 3 are meshed, the support frame 4 will be driven to move in the top chute of the rack plate 3 during rotation. The fixed seat 12 plays a role in fixing the sliding rod 7, so that the other end of the support frame 4 can slide along the sliding rod 7, thus playing a guiding role, enabling the support frame 4 to move horizontally and driving the vibrating rod 10 to move. The vibrating rod 10 can scrape off the concrete above the top of the mold body 1, so that the top can be kept flat, improving the leveling efficiency and ensuring the pouring quality. The vibrating component can reduce the air bubbles in the concrete and improve the overall strength. The ejection component prevents adhesion to the mold after solidification, facilitating the removal of the solidified concrete component.

[0024] Referring to Figure 2 , the ejection component includes a threaded rod 13, which is rotatably connected to the internal cavity of the mold body 1. Threaded blocks 15 are threadedly connected to both the left and right sides of the outer part of the threaded rod 13. The top of the threaded block 15 is rotatably connected to a connecting rod 16, and the other end of the connecting rod 16 is rotatably connected to an adapter block 17. The top of the adapter block 17 is fixedly connected to a support plate 18, and the top end of the support plate 18 is fixedly connected to a top plate 19. A second motor 14 is fixedly connected to the right side of the outside of the mold body 1, and the output end of the second motor 14 is fixedly connected to one end of the threaded rod 13. The two threaded blocks 15 are symmetrically arranged left and right, and the outside of the support plate 18 is slidably connected to the inside of the mold body 1.

[0025] Specifically, the second motor 14 is fixed by the mold body 1 to keep it stable during operation, and then drives the threaded rod 13 to rotate. At this time, the threaded blocks 15 on the left and right sides approach each other, which can drive the connecting rod 16 to move, and then push the adapter block 17 connected to the other end to move. The adapter block 17 is used to push the support plate 18 to slide inside the mold body 1, so as to push the top plate 19 to move, and then the concrete component inside the mold body 1 is ejected through the top plate 19, facilitating the workers to take it out and avoiding the situation that it is difficult to remove after solidification and adhesion to the mold.

[0026] Referring to Figure 1 , the vibrating component includes two cylinders 8, which are fixedly connected to the top of the support frame 4. The output ends of the two cylinders 8 penetrate the bottom wall of the support frame 4 and are fixedly connected to a moving plate 9, and two vibrating rods 10 are fixedly connected to the bottom of the moving plate 9.

[0027] Specifically, the cylinder 8 can be used to push the moving plate 9 to move vertically, so that the moving plate 9 drives the vibrating rod 10 to move, thereby inserting the vibrating rod 10 into the concrete. By vibrating, the air bubbles in it are reduced, making the concrete component more firm after solidification and ensuring the overall strength.

[0028] Referring to Figure 1 , a collection box 20 is fixedly connected to the front side of the mold body 1.

[0029] Specifically, the collection box 20 can be used to collect the scraped concrete, reducing material waste and lowering production costs.

[0030] Working principle: When using this mold, first inject the concrete into the mold body 1. When the concrete exceeds the highest point of the mold body 1, the motor 5 can be started. The motor 5 drives the gear 6 to rotate. Then, when the gear 6 meshes with the rack plate 3, the support frame 4 can slide in the groove at the top of the rack plate 3. At the same time, the other end of the support frame 4 will slide along the slide bar 7, so that it can move horizontally and drive the scraping plate 11 to move. The scraping plate 11 scrapes off the excess concrete, making the top surface flat, improving the leveling efficiency and ensuring the pouring quality. At the same time, the cylinder 8 can be used to push the moving plate 9 to move, so that the moving plate 9 drives the vibrating rod 10 to move downward and insert into the concrete. The vibration of the vibrating rod 10 can reduce the air bubbles in the concrete component, making it more firm after solidification and ensuring the overall strength. When taking out the concrete, the motor 2 14 can be started, and the operation of the motor 2 14 can drive the threaded rod 13 to rotate, so that the threaded blocks 15 on the left and right approach each other. The threaded blocks 15 drive the connecting rod 16 to move, and then push the connecting block 17 connected to the other end to move, so that the support plate 18 slides inside the mold body 1, and the concrete component inside the mold body 1 is pushed out by the top plate 19 at the top, facilitating the workers to take it out and avoiding the situation that it is difficult to remove after solidification and adhesion to the mold.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
