Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically a formwork release device for building construction. Background Technology

[0002] The main purpose of a mold release device is to help remove the molded specimen smoothly from the mold. The release device separates the molded specimen from the mold through mechanical operation or hydraulic means, thereby completing the demolding process. It is mainly used for civil engineering material testing and is suitable for demolding specimens such as cement concrete and asphalt concrete.

[0003] For example, the application with publication number CN211007679U discloses a formwork demolding device for building construction, including a left formwork. A demolding component is fixed to one side of the outer surface of the left formwork, and a moving component is fixed to the inner side of the middle of the demolding component. A right formwork is fixed to the outer surface of the demolding component away from the left formwork. The demolding component includes a support rib, a fixing frame, a motor, a bearing, a rotating shaft, a flange, and a first rack. This utility model has a simple structure and is easy to use. It optimizes the existing formwork demolding devices for building construction. Using the demolding component allows for rapid demolding of materials such as concrete inside the steel formwork after molding, eliminating the need for a large amount of manpower for manual demolding, reducing the risk factor in the demolding process. After demolding, it can be transported to another work point through a lifting ring, improving work efficiency.

[0004] However, as the demolding device in this application is used for a longer period of time, a lot of dust will accumulate on its surface. This will cause the template to be contaminated with dust after demolding, which may cause workers to inhale a lot of dust and harm their health. It is also inconvenient for workers to clean it. Utility Model Content

[0005] The purpose of this application is to provide a formwork release device for building construction in order to solve the problem of dust cleaning on the surface of the aforementioned release device.

[0006] The technical solution adopted in this application is as follows: a formwork demolding device for building construction, including a base, a U-shaped frame fixedly installed on the upper surface of the base, a motor housing installed on the outer surface of the U-shaped frame, a first drive motor installed on the inner surface of the motor housing, a bidirectional lead screw connected to the inner surface of the first drive motor, a threaded block installed on one side surface of the bidirectional lead screw, a groove opened on the inner surface of the threaded block, a support rod connected to the lower surface of the threaded block, a lifting plate connected to the lower surface of the support rod, a second drive motor installed on the outer surface of the lifting plate, a reciprocating lead screw installed on the inner surface of the second drive motor, a moving block installed on the outer surface of the reciprocating lead screw, a connecting frame installed on the lower outer surface of the lifting plate, a mounting frame connected to the lower surface of the moving block, a cleaning roller installed on the inner surface of the mounting frame, a connecting shaft installed on the lower inner surface of the mounting frame, a driven gear connected to the outer surface of the connecting shaft, a drive gear installed on the upper surface of the driven gear, and a drive rack installed on the lower surface of the connecting frame.

[0007] By adopting the above technical solution, the installation of the U-shaped frame makes the lower mobile lifting cleaning device more stable and safer to operate. The motor housing protects the internal first drive motor from damage, preventing external exposure and improving aesthetics. When the first drive motor is running, it drives the bidirectional lead screw installed in the groove to rotate, causing the surface threaded block to move back and forth to adjust the height of the lower support rod, ensuring stability and adaptability. A lifting plate installed on the lower surface of the support rod allows adjustment of the height of the cleaning roller installed below, thus adjusting the distance to the demolding device. The installation of the second drive motor allows the internal moving block to move back and forth, thereby driving the surface moving block to repeat the motion. The device moves back and forth, and a connecting frame is installed below the lifting plate. The mounting frame and cleaning roller allow the inner moving block to move, enabling the cleaning roller to move and clean the surface of the demolding device, making it adaptable and practical. During the reciprocating linear motion of the mounting frame, it drives the inner drive gear to reciprocate linearly. The drive gear meshes with the upper drive rack. During the movement, the drive rack drives the drive gear to rotate, which in turn drives the lower driven gear to rotate. The rotation of the driven gear also drives the inner connecting shaft to rotate. The connecting shaft is connected to the inner cleaning roller, so the rotation of the connecting shaft drives the cleaning roller to rotate, thereby cleaning the surface of the demolding device, making it versatile and practical.

[0008] In a preferred embodiment, a square tube is connected to the lower surface of the base, and a pin is installed on the outer surface of the square tube.

[0009] By adopting the above technical solution, installing pins on the surface of the square tube allows workers to more conveniently adjust the height of the upper device, avoiding the danger of the whole device shaking due to deviation during the adjustment process, thus making it more convenient and stable.

[0010] In a preferred embodiment, the lower surface of the pin is connected to a socket, the outer surface of the socket is provided with a support leg, and the lower surface of the support leg is fixedly mounted with a foot.

[0011] By adopting the above technical solution, and by setting feet on the surface of the socket, it is possible to more conveniently adjust to different heights to suit the device. The feet can be more stable during the adjustment process, and the support legs can make the upper pin more securely inserted and installed, thus making it convenient and stable.

[0012] In a preferred embodiment, a fixing seat is installed on the upper surface of the base, a stripping template is installed on the front surface of the fixing seat, a mold base is provided on the lower surface of the stripping template, a concave surface is formed on one side surface of the mold base, and a clamping seat is installed on the inner upper surface of the concave surface.

[0013] By adopting the above technical solution, the demolding of the surface construction template can be made more convenient and stable by installing clamping seats and template seats on the demolding surface. The template seat plays a clamping role, which prevents it from falling off during the demolding process. The installation concave surface cooperates with the top of the clamping seat below, making it convenient and adaptable.

[0014] In a preferred embodiment, the outer surface of the mold base is provided with a mounting member, the rear surface of the mounting member is connected to a rotating shaft, the rear surface of the rotating shaft is provided with a rotating seat, and the rear surface of the rotating seat is equipped with a fixing plate.

[0015] By adopting the above technical solution, the operation of the servo motor allows the rotating shaft to flip the device in front and the rotating base on the surface. The installation of mounting parts and fixing plates makes the device more stable and reliable during the flipping process, eliminating the danger caused by surface shaking, and making it versatile and stable.

[0016] In a preferred embodiment, a servo motor is connected to the rear surface of the fixing plate, and a bracket is mounted on the lower surface of the servo motor.

[0017] By adopting the above technical solution, the servo motor above can operate more stably by installing the bracket, effectively preventing the servo motor from falling during operation. Installing the servo motor allows the front-connected shaft and swivel to rotate, thereby allowing the front-connected device to rotate, making it stable and safe.

[0018] In a preferred embodiment, a guide rod is installed on the lower surface of the demolding template, and a guide cylinder is provided on the lower surface of the guide rod.

[0019] By adopting the above technical solution, a guide rod is installed inside the guide cylinder, which can raise and lower the demolding template on the upper surface, making it easier for workers to demold the template efficiently, thus making it practical and efficient.

[0020] In a preferred embodiment, a cylinder is provided on the lower surface of the demolding template, and a folding plate is installed on the lower surface of the cylinder.

[0021] By adopting the above technical solution, the surface demolding template can be raised and lowered by installing a cylinder, which effectively avoids the inconvenience, bumps and damage that may be caused by manual demolding. Installing a folding plate can make the cylinder above run more stably, giving it protection and safety.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, installing a U-shaped frame makes the lower mobile lifting cleaning device more stable and safer to operate. Installing a motor housing protects the internal first drive motor from damage, preventing external exposure and improving aesthetics. When the first drive motor is running, it drives the bidirectional lead screw installed in the groove to rotate, thereby causing the surface threaded block to move back and forth to adjust the height of the lower support rod, ensuring stability and adaptability. By installing a lifting plate on the lower surface of the support rod, the height of the cleaning roller installed below can be adjusted to regulate the distance to the demolding device. Installing a second drive motor allows the internal moving block to move back and forth repeatedly, which in turn drives the surface moving block to move back and forth repeatedly. The system is designed to be flexible and practical. A connecting frame is installed below the lifting plate. The mounting frame and cleaning roller allow the inner moving block to operate, enabling the cleaning roller to move and clean the surface of the demolding device. The mounting frame, in its reciprocating linear motion, drives the inner drive gear in the same direction. The drive gear meshes with the upper drive rack. During this motion, the drive rack drives the drive gear to rotate, which in turn drives the lower driven gear. The rotation of the driven gear also drives the inner connecting shaft to rotate. This connecting shaft connects to the inner cleaning roller, so its rotation drives the cleaning roller to rotate, thus cleaning the surface of the demolding device. Attached Figure Description
