Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete, and in particular to a quick demolding device for small precast components. Background Technology
[0002] With the rapid development of the construction industry, the application of precast components in modern construction is becoming increasingly widespread. To adapt to this trend, improve production efficiency, and ensure consistent product quality, an innovative small-scale precast component rapid demolding device has emerged. Given that traditional demolding methods can no longer meet the stringent speed and precision requirements of modern production, the emergence of this new device is particularly crucial.
[0003] In the current technology field, common demolding devices mainly include the following types:
[0004] Firstly, manual demolding tools are currently the most common method. These tools rely primarily on manual operation, using physical force to remove precast components from the mold. While these tools are relatively inexpensive, their efficiency is very limited. Prolonged repetitive labor can easily lead to worker fatigue, thus affecting work efficiency. Furthermore, manual operation can damage the integrity and appearance of the precast components, thereby affecting the quality of the final product.
[0005] Secondly, pneumatic demolding devices utilize air pressure to assist in demolding components. These devices are relatively simple to operate, but require a high-pressure air source. However, on some complex precast components, the air pressure may not be evenly distributed, leading to adhesion in certain areas and affecting the demolding effect.
[0006] Finally, mechanical demolding equipment includes various robotic arms, vibrating platforms, etc. These devices are highly automated and can significantly improve production efficiency. However, they are typically complex in structure, have high investment costs, and are relatively difficult to maintain, increasing the company's operating costs.
[0007] While each of these technologies has its own application areas, it also has some significant drawbacks. First, manual operation and traditional pneumatic methods often result in wasted time during production, leading to low overall production efficiency. Second, traditional demolding methods easily cause scratches or defects on the surface of precast components, affecting product quality. Furthermore, many existing technologies are difficult to adapt to precast components of different sizes and shapes, limiting their application scope. Finally, manual demolding increases the risk of accidents for operators, especially when handling large or heavy components, posing significant safety hazards. For small manufacturing enterprises, the high investment and maintenance costs of automated machinery are also a major burden, limiting their widespread application.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.
[0042] Example 1: Referring to all the accompanying drawings; A small precast component rapid demolding device, characterized in that,
[0043] The device includes two sets of symmetrically arranged U-shaped channel steels 4, which can be fitted onto the edge 5 of the template; the upper ends of the two sets of symmetrically arranged U-shaped channel steels 4 are connected by a crossbar; a long rod is arranged at the end of the two sets of symmetrically arranged U-shaped channel steels 4, the upper end of the long rod is the upper half 22 of the upright, and the lower end of the long rod is the lower half 21 of the upright.
[0044] The subsequent stent solution can be any of the following:
[0045] A. An arc-shaped section 3 is arranged below the two sets of symmetrically arranged U-shaped channel steels 4, and an end rod 7 is arranged at the other end of the two sets of symmetrically arranged U-shaped channel steels 4; the end rod 7 is arranged facing upward.
[0046] B. A vertical leg 10 is arranged at the other end of the two sets of symmetrically arranged U-shaped channel steels 4, with the vertical leg 10 arranged downwards.
[0047] The substantive technical effects and implementation process of the technical solution presented herein, i.e., its basic functions, are as follows:
[0048] For Option A: The purpose of the utility model is to solve the problem of the support legs of the demolding equipment hitting the edges of the cover plate during demolding, thus protecting the integrity of the edges and corners of the template; reducing the labor intensity of workers and improving demolding efficiency.
[0049] Method: Reduce labor intensity and improve demolding efficiency by processing demolding equipment and tools.
[0050] step:
[0051] Prerequisite: The concrete cover plate must reach the required demolding strength;
[0052] 1. Align the U-shaped channel steel on the demolding equipment horizontally with the upper edge (short side) of the mold;
[0053] 2. The operator holds the handle of the demolding equipment and pushes the demolding equipment forward. The arc-shaped part 3 serves as the propulsion part. The channel steel of the demolding equipment completely covers the short side of the upper edge of the mold.
[0054] 3. The operator rotates the demolding equipment 180° in the forward direction, and the operator moves accordingly to the corresponding position;
[0055] 4. The demolding equipment is placed stably, a buffer device is placed under the demolding equipment, and the operators are ready;
[0056] 5. The operator continues to apply pressure using the lever principle until the demolding device and mold are lifted. Then, the handrail is released and the cover plate falls freely downwards under its own weight. When the support leg of the demolding device touches the ground, the cover plate is removed from the mold and falls onto the buffer device. If the cover plate fails to fall off in one go, step 5 is repeated until the cover plate is removed.
[0057] 6. The workers remove the cover plate mold;
[0058] 7. Workers remove the demolding device;
[0059] 8. Workers use transport equipment to move the cover plate to the designated location.
[0060] Note: Waste tires can be used for the buffer device; rubber pads can be installed on the legs of the demolding device; rubber bushings can be installed on the support points.
[0061] For Option B: The fulcrum is located below the upright leg 10; after flipping over, during the tilting process, the template will tilt and guide to the ground in front, where a cushion can be placed.
[0062] When a demolding device is not used, four workers usually manually lift the mold, flip the mold and cover plate over, and then use a rubber hammer to hit the back of the mold to make the cover plate fall off. The above demolding method has the following drawbacks: low demolding efficiency; high labor intensity; potential damage to the mold; low mold reuse rate; increased cost; low cover plate integrity rate; and chipped edges and corners.
[0063] After using a demolding device:
[0064] 1. Demolding efficiency increased by 50%;
[0065] 2. Reduced labor intensity;
[0066] 3. The mold is not easily damaged;
[0067] 4. The mold reuse rate has been greatly improved;
[0068] 5. Reduced construction costs and eliminated the need for one worker;
[0069] 6. The cover plate has a high integrity rate, and the number of chipped edges and corners is greatly reduced.
[0070] Example 2: As a further improvement, parallel, or optional independent solution, a hand-held lever 1 is connected above the two symmetrically arranged U-shaped channel steels 4. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, is as follows: facilitating the application of pressure.
[0071] Example 3: As a further improvement, parallel, or optional independent solution, the handheld lever 1 has a U-shaped structure. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: both arms can exert force together.
[0072] Example 4: As a further improvement, parallel, or optional independent solution, the lower part of the supporting leg 10 includes casters. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, is as follows: facilitating propulsion and walking.
[0073] Example 5: As a further improvement, parallel, or optional independent solution, it also includes an auxiliary buffer mechanism 9. The substantive technical effect and implementation process of the technical solution herein, i.e., its basic function, are as follows: to protect the ground and the template.
[0074] Example 6: As a further improvement, parallel solution, or optional independent solution, the buffer mechanism 9 is a waste tire. The substantive technical effect and implementation process of the technical solution here, i.e., its basic function, are as follows: similar materials are all within the protection scope of this patent.
[0075] Example 7: As a further improvement, parallel solution, or optional independent solution, rubber bushings are installed at both the upper and lower ends of the long pole. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: safer contact with the ground.
[0076] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.
[0077] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.
[0078] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.
[0079] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
