Description

Technical Field

[0001] This utility model relates to the field of pier maintenance structure technology, and more specifically, to a membrane laying device for building construction. Background Technology

[0002] In the field of construction engineering, especially in the construction of infrastructure such as bridges and viaducts, concrete piers are widely used as a common supporting structure. In order to protect these piers from external environmental damage (such as rainwater, ultraviolet rays, and chemical corrosion) and to improve their durability and appearance, it is usually necessary to cover the surface of the piers with a protective film.

[0003] Traditional membrane laying methods for piers primarily rely on manual labor. Construction workers typically need to use aerial work platforms, scaffolding, and other equipment to ascend to heights and manually unroll and wrap the membrane around the pier. This method has several drawbacks: First, it is extremely inefficient, requiring multiple workers to coordinate, resulting in slow laying speed and severely impacting the overall construction progress. Second, the quality of the membrane laying is difficult to guarantee; manual wrapping easily leads to problems such as wrinkles, looseness, uneven overlap, or localized damage, significantly reducing the protective effect. Third, it poses high safety risks, as it involves working at heights and threatens the personal safety of construction workers. Furthermore, for piers with large cross-sectional dimensions or irregular shapes with tapers or curves, manual operation makes it even more difficult to achieve a smooth and tight fit of the membrane. Utility Model Content

[0004] The purpose of this utility model is to provide a membrane laying device for building construction, which addresses the shortcomings of the existing technology and solves the problems mentioned in the background.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a membrane laying device for building construction, including a mounting frame. The mounting frame is provided with a lifting structure for pulling a retainer to move along the extension direction of the pier. The hanging end of the lifting structure is provided with a retainer that slides along the extension direction of the pier. The retainer has an annular installation space, and two guide frames are installed in the installation space. Each guide frame has a mounting seat that is rotatably installed in it. A shaft for installing a film roll is detachably provided between the two mounting seats. The retainer is provided with a second driving structure for driving the mounting seats to rotate circumferentially along the guide frames.

[0006] In some technical solutions of this utility model, the lifting structure includes several electric chain hoists, which are arranged around the top of the mounting frame, and the traction rope inside the electric chain hoist is detachably connected to the retaining frame.

[0007] In some technical solutions of this utility model, one of the shafts is provided with a first driving structure for driving the shaft to rotate; The first drive structure includes a first drive motor mounted on a mounting base, and the output end of the first drive motor is connected to the shaft drive.

[0008] In some technical solutions of this utility model, the second drive structure includes a toothed belt arranged circumferentially on the outside of the mounting base, the toothed belt being connected end to end, a transmission gear meshing with the toothed belt being rotatably provided inside the guide frame, and a second drive motor meshing with the transmission gear being installed on the outer wall of the guide frame.

[0009] In some technical solutions of this utility model, an installation groove is provided on the outer side wall of the shaft, a spring plate is installed in the installation groove, the free end of the spring plate protrudes out of the installation groove and extends outward, and a limit plate is installed on the free end of the spring plate.

[0010] In some technical solutions of this utility model, a sleeve is installed on the shaft, the output end of the first drive motor is embedded in the sleeve, a limiting block is provided on the inner wall of the sleeve, and a limiting groove matching the limiting block is opened on the output end of the first drive motor.

[0011] In some technical solutions of this utility model, the retainer includes two ring-shaped frames arranged in pairs, and a plurality of connecting structures are arranged around the two ring-shaped frames.

[0012] In some technical solutions of this utility model, the connection structure includes several electric push rods, the body of the electric push rod is fixedly connected to one of the annular frames, and the telescopic end of the electric push rod is fixedly connected to another annular frame.

[0013] Compared to existing technologies, this invention has at least the following advantages or beneficial effects: The traction retainer descends slowly along the extension direction of the pier (usually vertically). As the retainer descends, the film roll mounted on the shaft moves downwards along with the retainer and is gradually pulled to rotate, subsequently pulling the film out circle by circle. Simultaneously, the second drive structure drives the mounting base to rotate circumferentially along the guide frame, thereby adjusting the film roll's rotational movement relative to the pier, allowing the film roll to move around the pier, thus laying the film on the pier surface. This allows the film laying angle (direction) to be actively and precisely controlled. It solves the problem that traditional equipment cannot dynamically adjust the film laying direction. The above structure can also effectively handle irregularly shaped piers with tapered, curved, or non-circular cross-sections, ensuring that the film is flat and tightly adhered to all sides of the pier, avoiding wrinkles and voids, thereby greatly improving the uniformity and quality of the film laying.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0023] Example This utility model provides a membrane laying device for building construction, such as Figures 1-6As shown, the device includes a mounting frame 1, on which a lifting structure 2 is provided for traction and movement of a retainer 3 along the extension direction of the pier 10. A retainer 3 is slidably mounted on the abutment end of the lifting structure 2 along the extension direction of the pier 10. The lifting structure 2 provides a vertical traction force, causing the retainer 3 to move downwards or upwards along the extension direction of the pier 10, thus enabling the film to be laid along the extension direction of the pier 10. An annular installation space is provided within the retainer 3, and two guide frames 4 are installed within this space. Each guide frame 4 has a rotatable mounting seat 5. A shaft 6 for mounting the film roll 9 is detachably provided between the two mounting seats 5. A second drive structure 8 is provided on the retainer 3 for driving the mounting seats 5 to rotate circumferentially along the guide frames 4. The annular mounting space within the retainer 3 and the guide frame 4 allow the mounting base 5 to rotate around the pier 10. The rotation speed is controlled by the second drive structure 8, enabling the film roll 9 to be laid laterally or diagonally around the pier 10, ensuring the film adheres tightly to the surface of the pier 10. This allows the film to be spirally wound around the surface of the pier 10 for curing. The detachable shaft 6 on the mounting base 5 facilitates quick replacement of the film roll 9, improving the operational flexibility of replacing the film roll 9 later. In practical use, the lifting structure 2 is first activated, causing the retainer 3 to slowly descend along the extension direction (usually vertical) of the pier 10. As the retainer 3 descends, the film roll 9 mounted on the shaft 6 moves downwards along with the retainer 3 and is gradually pulled to rotate, subsequently pulling the film out spirally. At the same time, the second drive structure 8 drives the mounting base 5 to rotate circumferentially along the guide frame 4, thereby adjusting the film roll 9 to rotate relative to the pier column 10, so that the film roll 9 can move around the pier column 10, thereby laying the film on the surface of the pier column 10.

[0024] In some technical solutions of this utility model, the lifting structure 2 includes several electric chain hoists 201, which are bolted around the top of the mounting frame 1. The number of electric chain hoists 201 is at least two. The traction rope inside each electric chain hoist 201 is detachably connected to the retainer 3. The electric chain hoists 201 provide reliable lifting force and achieve precise motion control through internal electrical controls, ensuring smooth movement of the retainer 3. The surrounding electric chain hoists 201 ensure even force distribution on the retainer 3, preventing tilting or swaying during movement, thereby improving the accuracy of film laying. Furthermore, the detachable connection between the traction rope and the retainer 3 allows for quick assembly during installation and disassembly of the retainer 3, facilitating maintenance and transportation, and enabling flexible arrangement of the device.

[0025] In some technical solutions of this utility model, one of the shafts is provided with a first driving structure 7 for driving the shaft 6 to rotate; The first drive structure 7 includes a first drive motor 701 mounted on the mounting base 5. The output end of the first drive motor 701 is connected to the shaft 6. The first drive motor 701 provides torque to directly drive the shaft 6 to rotate, thereby actively controlling the rotation speed of the film roll 9 and thus controlling the output speed of the film. This prevents the film from being too loose or too tight, which could cause the film roll 9 to fail to completely cover the pier 10. In operation, the first drive motor 701 is started, and it drives the shaft 6 to rotate through its output end, thereby controlling the release speed and tension of the film roll 9 to ensure that the film is laid flat on the outer wall of the pier 10. When the film roll 9 needs to be replaced, the detachable shaft 6 is removed from the mounting base 5, the used film roll 9 is replaced and a new film roll 9 is installed, and then the shaft 6 is inserted into the film roll 9 from the upper mounting base 5 and placed in the lower mounting base 5, where it is connected to the first drive motor 701 for transmission, allowing it to be used again.

[0026] In some technical solutions of this utility model, the second drive structure 8 includes a toothed belt 801 arranged circumferentially on the outside of the mounting base 5 along the guide frame 4. The toothed belt 801 is connected end to end. A transmission gear 802 is rotatably arranged inside the guide frame 4 and meshes with the toothed belt 801. A second drive motor 803 meshing with the transmission gear 802 is installed on the outer wall of the guide frame 4. The second drive motor 803 drives the mounting base 5 to make continuous rotational motion through the gear and toothed belt 801, ensuring that the mounting base 5 drives the film roll 9 to rotate smoothly. The film roll 9 can adapt to the curve or complex shape of the pier 10 and wrap the film tape around it to prevent its surface from being exposed, thereby improving the maintenance effect of this structure and improving the adaptability of this structure.

[0027] In some technical solutions of this utility model, an installation groove 601 is provided on the outer wall of the shaft 6, and a spring plate 602 is installed in the installation groove 601. The free end of the spring plate 602 protrudes out of the installation groove 601 and extends outward. A limiting plate 603 is installed on the free end of the spring plate 602. After the shaft 6 is inserted into the hollow film roll 9, the spring plate 602 provides radial pressure, causing the limiting plate 603 to move closer to the inner wall of the film roll 9, thereby quickly installing the film roll 9 on the shaft 6, preventing the film roll 9 from rotating during the film laying process, keeping the film conveying speed constant, and improving the reliability of the film laying of this structure.

[0028] In some technical solutions of this utility model, a sleeve 604 is installed on the shaft 6, and the output end of the first drive motor 701 is embedded in the sleeve 604. A limiting block 605 is provided on the inner wall of the sleeve 604, and a limiting groove 702 matching the limiting block 605 is opened on the output end of the first drive motor 701. When the output end of the first drive motor 701 is inserted into the sleeve 604 connected to the shaft 6, the limiting block 605 and the limiting groove 702 match to form a key connection, effectively transmitting torque. When disassembly is required, the shaft 6 can be pulled out to separate the two connections. The key connection formed by the sleeve 604 and the limiting block 605 can prevent slippage when the first drive motor 701 is transmitting power to the shaft 6, ensuring transmission efficiency, facilitating quick assembly and maintenance, and reducing downtime.

[0029] In some technical solutions of this utility model, the retainer 3 includes two paired annular frame bodies 301, with a plurality of connecting structures 302 arranged around the two annular frame bodies 301. The annular frame bodies 301 provide a robust frame structure, ensuring the stability of the mounting base 5 and the shaft 6, and bearing the load during the film laying process. After the connecting structures 302 are connected to the two annular frame bodies 301, they form an annular mounting space to enhance the overall rigidity. This ensures the stability of the mounting base 5 and the shaft 6 when rotating to the left and bears the load during the film laying process.

[0030] In some technical solutions of this utility model, the connecting structure 302 includes several electric push rods, with at least three electric push rods. The body of each electric push rod is fixedly connected to one of the annular frames 301, and the telescopic end of the electric push rod is fixedly connected to another annular frame 301. The electric push rods provide linear motion, precisely control the spacing of the annular frames 301, provide installation space for later replacement of formwork strips of different lengths, enhance the flexibility of the membrane laying device, and are suitable for various construction scenarios.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
