Description

Technical Field

[0001] This utility model relates to the field of concrete molding technology, specifically to a permeable concrete specimen molding device. Background Technology

[0002] Permeable concrete is one of the key types of concrete being developed and applied both domestically and internationally. It is an ecological concrete with excellent air and water permeability. Currently, there has been considerable research in China on the factors affecting the performance of permeable concrete. However, in routine research, the molding methods for permeable concrete specimens are inconsistent, the difficulty of operation varies, and there is a high degree of randomness. This results in poor consistency of the molded specimens, which to some extent affects the research on permeable concrete. Moreover, existing molds have technical problems such as easy corrosion, poor sealing, difficulty in disassembly, and fixed dimensions, which cannot guarantee the molding quality. The resulting concrete specimens have large dispersion, making it impossible to accurately, effectively, and quickly mold permeable concrete.

[0003] In response, Chinese patent application number CN202120366822.7 discloses a permeable concrete specimen molding device, including a base with a detachable molding mold on the base. Movable vibration components are located on the left and right sides of the molding mold. Each vibration component includes two threaded rods, each rotatably connected to the base. A forward / reverse motor is connected to the top of each threaded rod. A slider is threaded onto each threaded rod, and a guide hole is provided on the slider. A guide rod is installed within the guide hole. An electric push rod is fixedly connected to the side of the slider closest to the molding mold. A vibrating block is fixedly connected to the telescopic end of the electric push rod, and a vibrator is installed on the vibrating block. This utility model has a simple and reasonable structure, is easy to operate, and the molding mold is easy to disassemble, clean, and maintain. The interaction between the threaded rods and the sliders allows for flexible adjustment of the height of the vibrating block to accommodate molding molds of different heights, improving molding quality and enabling rapid and efficient concrete molding.

[0004] This device, by setting up a vibrating block that fits into the steel mold, can make the concrete in the mold more uniform and dense. However, the fit between the vibrating block and the steel mold is fixed, so it can only vibrate the concrete in a fixed position, which is a limited effect and the actual user experience is not ideal.

[0005] Therefore, in order to solve the above problems, a permeable concrete specimen molding device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a permeable concrete specimen molding device to solve the problem mentioned in the background art that the existing device can make the concrete in the mold more uniform and dense by setting a vibrating block that fits with the steel mold, but the fit position of the vibrating block and the steel mold is fixed, so it can only vibrate the concrete in a fixed position, which has a limited effect and the actual user experience is not ideal.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a permeable concrete specimen molding device, comprising: a base, a support mounted on the top surface of the base, a mold mounted on the top surface of the base via positioning bolts, and fastening bolts mounted on the mold;

[0008] The bracket is equipped with a movable structure, which includes a hydraulic rod. The hydraulic rod is fixedly installed on the top surface of the bracket. A first motor is fixedly connected to the extended end of the hydraulic rod. A mounting bracket is fixedly connected to the output end of the first motor. A threaded rod is movably installed on the bottom end of the mounting bracket via a bearing. A motor is installed on the side wall of the mounting bracket. Two sets of movable frames are slidably installed on the bottom surface of the mounting bracket. A connecting frame is connected to the bottom end of the movable frame. A roller is movably installed on the inner side of the connecting frame via a bearing. A second motor is fixedly installed on the side wall of the movable frame. A spring is fixedly connected to the output end of the second motor. A striking block is fixedly connected to the end of the spring.

[0009] Preferably, the first motor is located on the top side of the mold.

[0010] Preferably, the threaded rod passes through two sets of movable frames and is threadedly connected to the movable frames, and the output end of the motor is fixedly connected to the threaded rod.

[0011] Preferably, the two sets of movable frames are located on both sides of the mold, and the rollers are in contact with the outer wall of the mold.

[0012] Preferably, the spring and the striking block are located on one side of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a striking block, the connecting frame can be struck, and the force can be transmitted to the mold through the roller. The roller can rotate around the outer wall of the mold, and the striking position on the mold can be continuously adjusted, thereby adjusting the vibration position on the concrete and improving the molding effect of the concrete.

[0014] This invention features a movable structure. Activating the hydraulic rod lowers the first motor and mounting frame, bringing the rollers to both sides of the mold. Activating the motor then rotates a threaded rod connected to two sets of movable frames. The rotation of the threaded rod causes the two sets of movable frames to move closer together, bringing the rollers into contact with the outer wall of the mold. Activating the second motor rotates a spring, which in turn causes a striking block to strike the connecting frame, causing it to vibrate. This vibration is transmitted to the concrete through the rollers and the mold. Activating the first motor causes the mounting frame, movable frames, and connecting frame to rotate around the outer side of the mold, causing the rollers to roll against the outer wall of the mold. This continuous adjustment of the striking position on the mold, and consequently the vibration position on the concrete, improves the concrete forming effect. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 An embodiment of a permeable concrete specimen molding device provided by this utility model:

[0022] The base 1, bracket 11, mold 12, fastening bolt 13, positioning bolt 14, first motor 22, motor 25 and second motor 29 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A permeable concrete specimen molding device includes: a base 1, a bracket 11 installed on the top surface of the base 1, a mold 12 installed on the top surface of the base 1 by positioning bolts 14, and fastening bolts 13 installed on the mold 12.

[0024] A movable structure 2 is mounted on the bracket 11. The movable structure 2 includes a hydraulic rod 21, which is fixedly mounted on the top surface of the bracket 11. A first motor 22 is fixedly connected to the extended end of the hydraulic rod 21. A mounting bracket 23 is fixedly connected to the output end of the first motor 22. A threaded rod 24 is movably mounted on the bottom end of the mounting bracket 23 via a bearing. A motor 25 is mounted on the side wall of the mounting bracket 23. Two sets of movable brackets 26 are slidably mounted on the bottom surface of the mounting bracket 23. A connecting bracket 27 is connected to the bottom end of the movable bracket 26. A roller 28 is movably mounted on the inner side via a bearing. A second motor 29 is fixedly mounted on the side wall of the movable frame 26. A spring 210 is fixedly connected to the output end of the second motor 29. A striking block 211 is fixedly connected to the end of the spring 210. The striking block 211 can strike the connecting frame 27. The force can be transmitted to the mold 12 through the roller 28. The roller 28 can rotate around the outer wall of the mold 12, and the striking position on the mold 12 can be continuously adjusted, thereby adjusting the vibration position on the concrete and improving the molding effect of the concrete.

[0025] Furthermore, the first motor 22 is located directly above the mold 12, and the first motor 22 has a movable frame 26 that rotates around the mold 12.

[0026] Furthermore, the threaded rod 24 passes through the two sets of movable frames 26 and is threadedly connected to the movable frames 26. The output end of the motor 25 is fixedly connected to the threaded rod 24. The motor 25 provides power for the rotation of the threaded rod 24, and the rotation of the threaded rod 24 can drive the movement of the two sets of movable frames 26.

[0027] Furthermore, the two sets of movable frames 26 are located on both sides of the mold 12, and the roller 28 fits against the outer wall of the mold 12. The roller 28 can reduce the friction between the movable structure 2 and the mold 12, making it convenient to adjust the striking position of the movable structure 2 on the mold 12.

[0028] Furthermore, the spring 210 and the striking block 211 are located on one side of the connecting frame 27. When the spring 210 rotates, it can extend so that the striking block 211 strikes the connecting frame 27, thereby vibrating the mold 12.

[0029] Working principle: Before use, use fastening bolts 13 to splice and fix mold 12, use positioning bolts 14 to fix mold 12 on base 1, and add concrete to the inside of mold 12.

[0030] Start hydraulic rod 21, which drives the first motor 22 and mounting frame 23 to descend. At this time, the roller 28 descends to both sides of the mold 12. Start motor 25, which drives threaded rod 24 to rotate. Threaded rod 24 is threadedly connected to two sets of movable frames 26. The rotation of threaded rod 24 drives the two sets of movable frames 26 to move closer together. The movable frames 26 then drive the roller 28 to fit against the outer wall of the mold 12. Start second motor 29, which drives spring 210 to rotate. When spring 210 rotates, it drives striking block 211 to strike connecting frame 27, causing the connecting frame 27 to vibrate. The vibration can be transmitted to the concrete through roller 28 and mold 12. Start first motor 22, which drives mounting frame 23, movable frame 26, and connecting frame 27 to rotate around the outside of mold 12. The roller 28 then rolls against the outer wall of mold 12. The striking position on mold 12 can be continuously adjusted, thereby adjusting the vibration position on concrete and improving the molding effect of concrete.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
