The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0029] Figure 1 2 is a schematic structural diagram of a film pulling device according to an embodiment of the present application; Figure 2 This is an exploded view of a film puller according to an embodiment of the present application; Figure 3 This is a schematic diagram of the lower plate structure of the film pulling device according to an embodiment of the present application;
[0030] like Figures 1 to 3As shown, the present application provides a film stretcher, which includes: a clamping component 1, an adjusting component 2, a guide component 3, and a connecting component 4; the clamping component 1 includes an upper clamping plate 11 and a lower clamping plate 12, and the upper clamping plate 11 can be movably installed on the lower clamping plate 12, so that the upper clamping plate 11 and the lower clamping plate 12 form a clamping space, and the clamping space is used to adapt to the clamped structure 6 and fix the film stretcher on the clamped structure 6; the adjusting component 2 includes at least one screw 21 and at least one nut 22 matching the screw 21, The screw 21 is fixedly mounted on the lower clamping plate 12 in a manner parallel to its length. The guide assembly 3 is mounted on the free end of the screw 21 in a sliding connection and contacts the nut 22, allowing the position of the guide assembly 3 on the screw 21 to be adjusted via the nut 22. One end of the connecting assembly 4 is fixed to the rope membrane 5, and the other end is fixed to the guide assembly 3, so that the rope membrane 5 moves in response to the displacement generated by the rotation of the nut 22 on the screw 21, thereby stretching the membrane to a predetermined position. This simplifies operation, improves construction efficiency, and reduces labor costs.
[0031] Optionally, the upper clamping plate 11 includes a clamping top plate 111 and a limiting plate 112, the clamping top plate 111 is a rectangular plate structure, and the limiting plate 112 is fixedly installed on the clamping top plate 111 in a direction perpendicular to the clamping top plate 111 to limit the clamped structural member 6.
[0032] In this embodiment, the vertical fixation of the limiting plate 112 can effectively limit the lateral movement of the clamped structural member 6, ensuring that the structural member will not produce unnecessary offset during the clamping process, thereby improving the stability and reliability of the clamping. In addition, the addition of the limiting plate 112 provides an additional positioning reference for the clamped structural member 6, making the position of the structural member on the clamping top plate 111 more controllable, and reducing the installation error caused by position deviation. Moreover, the combination of the clamping top plate 111 of the rectangular plate structure and the vertical limiting plate 112 not only provides sufficient contact area to evenly distribute the clamping force, but also optimizes space utilization through the structure of the limiting plate 112, so that the film stretcher can achieve efficient clamping in a limited space. Furthermore, the use of the limiting plate 112 in conjunction with the clamping top plate 111 can avoid excessive concentration of the clamping force on a certain area of the structural member, reducing the risk of structural member damage due to excessive local force.
[0033] Optionally, the lower clamping plate 12 includes a clamping bottom plate 121, a side plate 122 and a supporting component 123, and the clamping top plate 111 and the side plate 122 are both rectangular plate-shaped structures, which are fixed together in a perpendicular manner; the supporting component 123 is fixedly connected to the bottom plate and the side plate 122 respectively to form a rectangular support structure with one side open, so that the structure of the clamping assembly 1 is stable.
[0034] In this embodiment, the rectangular support structure provides good geometric stability, ensures the rigidity and deformation resistance of the lower clamping plate 12 when subjected to external forces, and improves the overall structural stability of the clamping assembly 1. In addition, the vertical connection between the clamping base plate 121 and the side plate 122 forms a closed clamping space, which can more effectively fix and constrain the clamped structural member 6, prevent it from moving or twisting during operation, and improve the reliability and precision of the clamping. In addition, the addition of the support component 123 not only enhances the stability of the structure, but also helps to evenly distribute the pressure from the clamping top plate 111, avoids excessive local force, and reduces the risk of damage to the structural member. Furthermore, the stable structural design reduces the uncertainty during operation, reduces the risk of operational errors or safety accidents caused by structural instability, and improves the safety of operation. At the same time, the design of the rectangular support structure can adapt to clamped structural members 6 of different sizes and shapes. By adjusting the sizes of the clamping base plate 121 and the side plate 122, it can meet the needs of various construction scenarios, thereby improving the versatility and flexibility of the system. Finally, the open design of the rectangular structure makes it easy to inspect and maintain the internal components, and also facilitates adjustment or replacement according to actual needs, reducing maintenance costs and time.
[0035] Optionally, a first through hole 1111 is provided on the clamping top plate 111, and a second through hole 1211 is provided on the clamping bottom plate 121. The first through hole 1111 and the second through hole 1211 correspond in position to each other, so that the bolt 13 passes through the first through hole 1111 and the second through hole 1211, and forms a clamping space between the clamping top plate 111 and the clamping bottom plate 121.
[0036] In this embodiment, by passing the bolt 13 through the first through hole 1111 and the second through hole 1211, the clamping top plate 111 and the clamping bottom plate 121 can be tightly fixed together to form a stable clamping space, ensuring that the clamped structural member 6 will not slide or deflect during operation, thereby improving the stability and reliability of the clamping. In addition, the position-corresponding through-hole design makes the insertion of the bolt 13 intuitive and simple, without the need for complicated alignment or adjustment, thereby speeding up the installation speed of the clamping assembly 1. At the same time, this also makes the disassembly process equally quick, facilitating the rapid replacement or adjustment of the clamped structural member 6. In addition, the cooperation between the bolt 13 and the through-hole not only provides a fast connection, but also enhances the structural strength between the clamping top plate 111 and the clamping bottom plate 121, so that the clamping assembly 1 can withstand greater external forces, thereby improving the durability and service life of the entire system. Furthermore, the precise alignment of the first through hole 1111 and the second through hole 1211 ensures uniform force transmission within the clamping assembly 1, avoids structural damage or clamping failure caused by local excessive force, and improves the efficiency and safety of force transmission. At the same time, by adjusting the size and position of the first through hole 1111 and the second through hole 1211, it can adapt to clamped structural parts 6 of different sizes and shapes, thereby improving the versatility of the clamping assembly 1 and its adaptability to different application scenarios. Finally, the design of through holes with corresponding positions simplifies the design and manufacturing process of the clamping assembly 1, reduces the need for special processing technology, reduces production costs, and also facilitates mass production and quality control.
[0037] Optionally, the screw rod 21 is fixedly mounted on the side plate 122 .
[0038] In this embodiment, the screw 21 is fixedly mounted on the side plate 122, which can ensure the stability of the screw 21 during operation, avoid adjustment misalignment caused by shaking or displacement of the screw 21, and improve the structural stability and reliability of the entire film stretcher. In addition, the fixed connection between the screw 21 and the side plate 122 can effectively transmit the force generated by the adjustment component 2 to the guide component 3, ensuring that the guide component 3 can move smoothly along the screw 21, achieve the stretching and positioning of the rope membrane cloth 5, and improve the efficiency and accuracy of force transmission. Furthermore, by fixing the screw 21 on the side plate 122, the structural design of the adjustment component 2 is simplified, additional support or fixed components are avoided, and friction and wear between components are reduced, making the adjustment process smoother, reducing maintenance costs and failure rates. At the same time, the screw 21 fixed on the side plate 122 provides an intuitive adjustment point for the operator, making the action of rotating the nut 22 to adjust the position of the guide component 3 simpler and more direct, improving the convenience and efficiency of operation. Furthermore, the design of screw 21 fixed to side plate 122 enables adjustment assembly 2 to accommodate clamped structural members 6 of varying sizes and shapes. By adjusting the length and position of screw 21, the system can be tailored to meet the needs of various construction scenarios, enhancing the system's versatility and flexibility. Finally, fixing screw 21 to side plate 122 simplifies the production and assembly process, reducing reliance on specialized processing techniques and tools, lowering manufacturing costs, and facilitating mass production and quality control.
[0039] Optionally, the guide assembly 3 is a baffle 31, and the baffle 31 is provided with the same number of third through holes 311 as the screw 21. The third through holes 311 are arranged corresponding to the positions of the screw 21. The third through holes 311 pass through the screw 21, so that the baffle 31 can slide along the screw 21.
[0040] In this embodiment, the third through hole 311 on the baffle 31 corresponds to the position of the screw 21, allowing the baffle 31 to slide smoothly along the screw 21. At the same time, due to the guiding effect of the screw 21, the movement path of the baffle 31 is controlled, ensuring the smoothness and positioning accuracy of the guide assembly 3 during the adjustment process. In addition, by rotating the nut 22 to adjust the position of the baffle 31 on the screw 21, the tension of the connecting assembly 4 can be flexibly changed, thereby controlling the degree of stretching of the rope membrane 5, meeting different construction requirements, and improving the adjustment flexibility and adaptability of the membrane stretcher. Furthermore, the use of the baffle 31 in conjunction with the screw 21 simplifies the structure of the guide assembly 3, avoids complex or additional guiding devices, makes the adjustment mechanism more concise and efficient, and reduces production costs and maintenance difficulties. The design of the third through hole 311 on the baffle 31 allows the operator to intuitively adjust the position of the baffle 31 by rotating the nut 22. The operation process is simple and intuitive, which improves construction efficiency and operator convenience. At the same time, the tight fit between baffle 31 and screw 21 effectively prevents the guide assembly 3 from shaking or deflecting during operation, improving the stability and reliability of the entire film stretcher system. Finally, the smooth sliding properties of baffle 31, acting as the guide assembly 3, ensure that the force transmitted from the adjustment assembly 2 is evenly and continuously transmitted to the connecting assembly 4, improving the efficiency and precision of force transmission.
[0041] Optionally, the baffle 31 is further provided with the same number of fourth through holes 312 as the number of the connecting components 4 . The connecting components 4 correspond to the fourth through holes 312 one by one and pass through the fourth through holes 312 to be fixed on the baffle 31 .
[0042] In this embodiment, by passing the connecting assembly 4 through a matching number of fourth through holes 312 and fixing it to the baffle 31, each connecting assembly 4 can be ensured to have an independent and stable fixing point, avoiding shaking or misalignment of the connecting assembly 4 during use, and improving the stability and reliability between the connecting assembly 4 and the guide assembly 3. In addition, each connecting assembly 4 corresponds one-to-one with the fourth through holes 312 on the baffle 31, ensuring uniform force transmission, avoiding localized excessive force caused by concentrated force distribution, improving the efficiency and smoothness of force transmission, and reducing the risk of damage to the structural components. Furthermore, the design of the fourth through holes 312 makes the installation of the connecting assembly 4 intuitive and simple, eliminating the need for complex alignment or adjustment, and speeding up installation. At the same time, when the tension of the connecting assembly 4 needs to be adjusted, it is only necessary to adjust the position of the baffle 31 on the screw 21, simplifying the adjustment process and improving construction efficiency. On the other hand, by adjusting the position and number of the fourth through holes 312, it is possible to adapt to connecting assemblies 4 of different sizes and quantities, allowing the guide assembly 3 to flexibly respond to various construction scenarios and needs, thereby improving the versatility and adaptability of the system. Furthermore, the one-to-one correspondence between the connecting components 4 and the fourth through-holes 312 on the baffle 31 not only ensures the independent operation of each connecting component 4 but also enhances the coordination between the components within the system, improving the overall operational efficiency and consistency of the film stretcher. Finally, the design of the fourth through-holes 312 simplifies the design and manufacturing process of the guide component 3, reducing the need for specialized processing techniques, lowering production costs, and facilitating mass production and quality control.
[0043] Optionally, two reinforcing ribs 313 are further provided on the baffle 31 , and the two reinforcing ribs 313 are fixedly mounted on the two long sides of the baffle 31 in parallel with the length direction of the baffle 31 , so as to enhance the structural stability of the baffle 31 .
[0044] In this embodiment, the addition of the reinforcing ribs 313 significantly enhances the structural strength of the baffle 31, especially in the longitudinal direction, which helps to resist the bending stress caused by external loads or during operation, and ensures that the baffle 31 will not easily deform when subjected to force. In addition, by fixing the reinforcing ribs 313 on the two long sides of the baffle 31, the rigidity of the baffle 31 can be effectively increased, preventing shaking or instability during use, and ensuring the stability and reliability of the guide assembly 3 during adjustment and use. In addition, the reinforcing ribs 313 not only strengthen the structure of the baffle 31 itself, but also play a role in optimizing the force transmission path, ensuring that the force transmitted from the adjustment assembly 2 can be more evenly distributed to the baffle 31, thereby improving the efficiency and balance of force transmission. Furthermore, compared to increasing the thickness of the baffle 31 or the use of other materials, by adding reinforcing ribs 313 at key positions to increase the structural strength, the overall material usage can be reduced, reducing manufacturing costs, while also reducing the weight of the film stretcher and improving portability and operability. Furthermore, the addition of reinforcing ribs 313 ensures that baffle 31 maintains its performance even under prolonged use and frequent operation, reducing damage caused by structural fatigue or external impact, thereby increasing the durability and service life of the film stretcher. Finally, the layout of reinforcing ribs 313 ensures that even minor damage to a portion of baffle 31 will not affect the function of the entire guide assembly 3, simplifying maintenance and overhaul procedures and reducing maintenance costs and downtime.
[0045] Optionally, the connection component 4 is two wire rings 41.
[0046] In this embodiment, the wire ring 41, with its inherent flexibility, can adapt to the edges of the membrane cloth of different shapes and sizes. Even if the shape of the membrane cloth changes during the stretching process of the membrane cloth rope, the wire ring 41 can adjust accordingly to ensure the stability and reliability of the connection. In addition, the use of the wire ring 41 as the connecting component 4 makes the installation and disassembly process very convenient. The wire ring 41 has a quick socket device, and a quick connection can be achieved by tightening the corresponding socket component, thereby improving construction efficiency. Moreover, compared with some more complex connecting components 4, the wire ring 41 is relatively low in cost and easy to purchase and store, reducing material costs and logistics costs. This is particularly important for large-scale construction projects. Furthermore, the wire ring 41 has a simple structure and can be easily replaced in the event of wear or damage without the need for complex tools or expertise, thereby reducing maintenance costs and downtime. At the same time, the connection method of the wire ring 41 can evenly distribute force, avoiding damage to the membrane cloth or connecting component 4 due to excessive local force, thereby improving the safety and reliability of the entire membrane stretcher system. Finally, the wire traveler 41 generally has good weather resistance and corrosion resistance, and can maintain good performance even in humid or dusty environments, ensuring normal operation under various construction conditions.
[0047] Optionally, the number of the screw rod 21 and the number of the nut 22 are both 2.
[0048] In this embodiment, the use of two screws 21 and corresponding nuts 22 can provide a more uniform force distribution, ensure the stability and smoothness of the guide assembly 3 during movement, and reduce structural offset or wear caused by uneven force at a single point. In addition, the synchronous adjustment of the two screws 21 makes the movement of the guide assembly 3 more controllable, avoids the position deviation that may be caused by a single screw 21, and improves the positioning accuracy and consistency during the membrane stretching process. Furthermore, the twin-screw 21 design can more effectively disperse and transmit the force from the adjustment assembly 2 to the guide assembly 3, reduce the concentration of force, ensure uniform distribution of force, and improve the efficiency of force transmission and the overall coordination of the system. The twin-screw 21 and bolt 13 design can also reduce maintenance costs and improve the cost-effectiveness of the entire membrane stretcher system.
[0049] Optionally, the screw 21 is an M12 screw 21 , and the nut 22 is an M12 nut.
[0050] In this embodiment, the M12 thread specification is one of the international standards. The use of M12 screws 21 and nuts 22 can ensure compatibility with standard fasteners widely available on the market, improve the interchangeability of parts and the flexibility of the supply chain, and simplify the procurement and maintenance process. In addition, the M12 screw 21 and nut 22 provide sufficient load-bearing capacity and stability, and can withstand the large torque and tension generated during the operation of the film stretcher, ensuring the smoothness and reliability of the guide assembly 3 during sliding adjustment. In addition, due to its standardization and wide application, the production cost of the M12 screw 21 and nut 22 is relatively low, and it is easy to purchase in large quantities, which reduces the manufacturing cost of the film stretcher. At the same time, the standardized design is also conducive to reducing maintenance costs and improving cost-effectiveness. Finally, the use of M12 screws 21 and nuts 22 that meet international standards ensures the safety and compliance of the film stretcher design and manufacturing process, meets industry standards and specifications, and improves the overall reliability and safety of the system.
[0051] Optionally, the clamping top plate 111 and the positioning plate are both steel plates and are fixed together by welding.
[0052] In this embodiment, the steel plate can withstand large external forces due to its high rigidity and strength, ensuring the structural stability and reliability of the clamping assembly 1 during use. Welding, as a permanent connection method, further enhances the strength of the connection point and avoids loosening or breaking under high loads or harsh environments. In addition, the welding fixation of the positioning plate and the clamping top plate 111 ensures that the relative position relationship between the two will not be changed by external factors, improves the positioning accuracy of the clamping assembly 1 on the clamped structure 6, and ensures the accuracy during the membrane stretching process. Furthermore, the welding connection provides a rigid force transmission path, so that the force transmitted from the adjustment assembly 2 can be efficiently and directly transmitted to the clamped structure 6, improving the efficiency of force transmission and the overall coordination of the system. At the same time, the welding fixation method simplifies the installation process of the clamping assembly 1, eliminates the need for additional fasteners, reduces installation time and cost, and the stability of the welded connection reduces maintenance frequency, reducing maintenance costs and downtime. Finally, the high corrosion resistance and wear resistance of the steel plate, coupled with the permanent connection of welding, enable the clamping assembly 1 to maintain good performance for a long time in harsh construction environments, improving the durability and service life of the membrane stretcher.
