Description

Technical Field

[0001] This utility model relates to the field of precast component molding technology, specifically a precast component vibration molding device. Background Technology

[0002] In the production of precast components, vibration molding technology is a key process to ensure the density, strength and surface quality of the components. Vibration molding rearranges concrete particles and removes air through mechanical vibration, which significantly improves the density of the concrete. Vibration molding technology requires a vibration molding device to achieve this.

[0003] However, when existing precast concrete pipe components are formed using vibration molding devices, the mold of the precast component along with the component is usually placed directly on the vibration platform of the device without any reinforcement or restraint on the mold. When the mold vibrates with the vibration platform, it is easy to slip along the platform, making it difficult for the mold and the precast component inside the mold to remain stable on the device. In addition, existing precast component vibration molding devices can only meet the vibration requirements of precast components of specific sizes, and cannot meet the vibration requirements of components such as concrete cover plates, making them inflexible in use and limiting the scope of application of the vibration device. Utility Model Content

[0004] The purpose of this utility model is to provide a precast component vibration molding device to solve the problem that existing vibration devices are not easy to keep the mold stable on the vibration platform and are not flexible enough, thus limiting their application range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast component vibration molding device, comprising a base, an internally threaded cylinder provided at the center of the top of the base, a threaded column connected inside the internally threaded cylinder, a column fixedly connected to the top of the threaded column, a plurality of screws provided on the outer wall of the column, a sleeve provided on the outer sleeve of the screws, a ball bearing rotatably connected to the end of the sleeve, a vibration platform provided on the top of the base, a plurality of vibration motors installed at the bottom of the vibration platform, shock absorbers provided at the four corners of the bottom of the vibration platform, a limit groove provided at the top of the vibration platform, a movable ring and a corner block respectively provided on the inner side of the limit groove, and a limit corner plate provided at the four corners of the top of the limit groove.

[0006] Preferably, a through hole is provided in the middle of the limiting groove, and the column is connected to the vibration platform through the through hole.

[0007] Preferably, there are two movable rings, and each of the two movable rings has a limiting hole on its inner side, and the movable ring is movably embedded and connected to the limiting groove.

[0008] Preferably, the corner block has a round hole at its top, and the corner block is movably embedded in the limiting groove through the round hole.

[0009] Preferably, the sleeve is rotatably connected to the column via a screw.

[0010] Preferably, the number of vibration motors is set to four, and the four vibration motors are symmetrically arranged at the bottom end of the vibration platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This precast component vibration molding device, through a column, screw, sleeve, and ball bearings, allows the precast pipe component and its mold to be lowered down along the column to the top of the vibration platform when the precast pipe component needs to be placed vertically on the vibration platform. At this time, the column and the sleeve outside the column will drive the ball bearings to fit against the inner wall of the mold, so that the precast pipe component and its mold can be limited and reinforced on the platform. At the same time, the bottom of the mold can be embedded in the corresponding limiting hole, which helps the precast pipe component and mold maintain better stability on the vibration device.

[0013] 2. This precast component vibration molding device, through threaded columns and internal threaded cylinders, allows the columns on the vibration platform to be disassembled. Combined with corner blocks, limiting corner plates, and limiting grooves, it enables flat precast components such as concrete slabs to be stably placed on the vibration platform for vibration. This allows the structure of the vibration platform to be flexibly adjusted to meet the vibration requirements of different types of precast components, thereby reducing the probability of the vibration platform's application range being limited.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this embodiment includes a base 12, which supports the column 1 and the vibration platform 11. An internally threaded cylinder 15 is provided in the middle of the base 12. The threaded column 14 engages with the thread inside the internally threaded cylinder 15 and can be fixed to the base 12 via the internally threaded cylinder 15, thus fixing the column 1 to the base 12 and facilitating the removal of the column 1 from the base 12. The top of the threaded column 14 is fixedly connected to the column 1. The column 1 is located in the middle of the vibration platform 11, and its outer diameter is much smaller than that of the prefabricated pipe component mold. The inner diameter allows the mold for the precast pipe component to slide smoothly onto the outside of the column 1. Multiple screws 2 are provided on the outer wall of the column 1. The function of the screws 2 is to allow the sleeve 3 to move outward along the outer wall of the column 1, so that the ball bearings 4 at the end of the sleeve 3 can be flexibly adjusted according to the mold size with different inner diameters, thereby improving the flexibility of the device during use. The sleeve 3 is threaded on the outer wall of the screw 2, and the sleeve 3 has internal threads, allowing it to rotate along the outer wall of the screw 2. A ball bearing 4 is rotatably connected to the end of the sleeve 3. The surface of base 4 is smooth, allowing it to slide against the inner wall of the precast component mold, thus supporting the mold. A vibration platform 11 is located on the top of base 12. The function of vibration platform 11 is to support the mold and the precast components inside. Multiple vibration motors 13 are installed at the bottom of vibration platform 11. Shock absorbers 10 are installed at the four corners of the bottom of vibration platform 11. The function of shock absorbers 10 is to reduce the vibration transmitted to base 12, thereby preventing vibration from being transmitted to the ground through base 12. It should be noted that to prevent the shock absorbers 10 from damaging the vibration platform 12... The bottom damping effect affects the vibration molding requirements of the entire precast component. The connection between the damper 10 and the vibration platform 11 can be treated by hinge or other methods to avoid affecting the vibration effect at the bottom of the vibration platform 11. The top of the vibration platform 11 is provided with a limiting groove 17. The limiting groove 17 is square and can limit the mold of square components such as concrete cover plates. The inner side of the limiting groove 17 is provided with a movable ring 7 and a corner block 8. The four corners of the top of the limiting groove 17 are provided with limiting corner plates 9. The function of the limiting corner plates 9 is to reinforce the mold of the square precast component.

[0021] Specifically, a through hole 5 is provided in the middle of the limiting groove 17, and the column 1 is connected to the vibration platform 11 through the through hole 5. Furthermore, there are two movable rings 7, and each movable ring 7 has a limiting hole 6 on its inner side. The movable rings 7 are movably embedded in the limiting groove 17. The two movable rings 7 have different diameters, but they can be nested and arranged in the limiting groove 17, so as to form limiting holes 6 of different sizes in the limiting groove 17, so as to limit the bottom of the prefabricated pipe component mold.

[0022] Furthermore, a round hole 16 is provided at the top of the corner block 8. The corner block 8 is movably embedded and connected to the limiting groove 17 through the round hole 16. There are four corner blocks 8, which can protect the inner corner of the square limiting groove 17, thereby helping to extend the service life of the limiting groove 17.

[0023] Furthermore, the bottom end of the shock absorber 10 is fixedly connected to the top end of the base 12. The function of the shock absorber 10 is to reduce the vibration transmitted to the base 12, thereby reducing the probability of vibration occurring on the ground where the device is located.

[0024] Furthermore, the sleeve 3 is rotatably connected to the column 1 via the screw 2. The sleeve 3 can extend the length of its end via the screw 2, which facilitates the fitting of the end ball 4 with the inner wall of the precast component mold with different inner diameters, thereby better protecting the precast component mold and the precast component.

[0025] Furthermore, the number of vibration motors 13 is set to four, and the four vibration motors 13 are symmetrically arranged at the bottom of the vibration platform 11, so that the vibration generated by the vibration platform 11 can be more symmetrical and uniform, thereby improving the vibration effect of this vibration device.

[0026] The usage method of this embodiment is as follows: When using the device, first connect it to an external power supply. Then, according to the inner diameter of the mold of the precast pipe component to be vibrated, rotate the sleeve 3 along the screw 2 so that the end of the sleeve 3 can be adapted to the inner diameter of the mold of the precast pipe component. Next, the mold of the precast pipe component can be lifted to the top of the vibration platform 11 by a crane, and then the mold is lowered onto the vibration platform 11. At this time, the column 1 in the middle of the vibration platform 11 will be inside the mold of the precast pipe component, and the sleeve 3 on the outside of the column 1 and the ball bearings 4 on the sleeve 3 will roll against the inner wall of the mold until the bottom of the mold is stably placed in the limiting hole 6 where the movable ring 7 is located on the vibration platform 11. At this time, the mold of the precast pipe component will be reinforced and limited on the vibration platform 11. Then, the vibration motor 13 can be started, so that the vibration motor 13 drives the vibration platform 11 to vibrate. Then, the vibration platform 11 will drive the mold of the precast pipe component to vibrate. At this time, the precast pipe component in the mold begins to vibrate and form. When it is necessary to vibrate the precast components such as concrete cover plates, simply rotate the threaded column 14 at the bottom of the column 1 along the internal threaded cylinder 15 in the middle of the base 12 to remove the column 1 from the base 12. Then, remove the movable ring 7 and the corner block 8 from the limiting groove 17. Then, put the mold of the precast plate component into the limiting groove 17 so that the mold fits with the limiting corner plates 9 at the four corners of the limiting groove 17.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
