Description

Technical Field

[0001] This utility model belongs to the technical field of building curtain wall fixtures, and in particular relates to a torque converter. Background Technology

[0002] Building curtain walls are common exterior envelope structures in modern buildings. Essentially, they are non-load-bearing exterior wall systems primarily used to isolate and protect the building's internal and external environments while enhancing its overall aesthetics. A curtain wall typically consists of two parts: first, the outer decorative and protective panels, such as glass, metal panels, stone, or ceramic panels; and second, the support system located behind the panels, which bears the structural load. Common forms include aluminum alloy beams, columns, steel components, and end supports.

[0003] In the installation of curtain wall systems, structural components such as beams and columns are arranged in an interlaced manner and are usually fastened together with bolts. Due to the interlacing arrangement of beams and columns in the curtain wall system, tightening bolts is generally done manually using a wrench or screwdriver. However, using a conventional wrench or screwdriver to tighten bolts is often inefficient, and manual tightening often results in insufficient preload. Utility Model Content

[0004] The purpose of this application is to provide a torque converter that aims to solve the problem of how to improve the working efficiency and reliability of bolts in curtain wall systems.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A torque converter is provided, comprising: a first side plate, a second side plate, a positioning block, a driving sprocket, a driven sprocket, a chain, and a driver. The first side plate and the second side plate are elongated and arranged opposite to each other. The driving sprocket and the driven sprocket are both located between the first side plate and the second side plate. The two ends of the driving sprocket are rotatably connected to one end of the first side plate and one end of the second side plate, respectively. The two ends of the driven sprocket are rotatably connected to the other ends of the first side plate and the other end of the second side plate, respectively. The two ends of the chain are respectively engaged with the driving sprocket and the driven sprocket. The positioning block is located between the first side plate and the second side plate, and the two ends of the positioning block are respectively connected to the first side plate and the second side plate. Two positioning blocks are arranged at intervals along the length direction of the first side plate or the second side plate. The driver is used to drive the driving sprocket to rotate.

[0007] In some embodiments, the two positioning blocks are located between the driving sprocket and the driven sprocket along the length direction of the first side plate or the second side plate.

[0008] In some embodiments, multiple chains are arranged at intervals, and each chain engages with both the driving sprocket and the driven sprocket.

[0009] In some embodiments, the first side plate has a positioning through hole, the positioning block has a positioning threaded hole at the position where it connects to the first side plate, the first side plate has a positioning through hole at the position corresponding to the positioning threaded hole, and the torque converter further includes a positioning bolt, one end of which passes through the positioning through hole and is screwed into the positioning threaded hole.

[0010] In some embodiments, a limiting cavity is further formed on the surface of the first side plate facing the positioning block, the positioning through hole is formed at the bottom of the limiting cavity, the positioning block is provided with a limiting part protruding into the limiting cavity, and the positioning threaded hole is at least partially located in the limiting part.

[0011] In some embodiments, the second side plate has a positioning groove, and the positioning block has a positioning part protruding into the positioning groove.

[0012] In some embodiments, the driven sprocket includes a driven shaft, driven teeth disposed on the side surface of the driven shaft, and a drive head located at one end of the driven shaft. The two ends of the driven shaft are rotatably connected to the first side plate and the second side plate, respectively, and a plurality of driven teeth are arranged circumferentially around the driven shaft.

[0013] In some embodiments, the drive sprocket includes a drive shaft, drive teeth disposed on the side surface of the drive shaft, and a transmission sleeve connected to one end of the drive shaft. The two ends of the drive shaft are rotatably connected to the first side plate and the second side plate, respectively. Multiple drive teeth are arranged circumferentially around the drive shaft. The transmission sleeve is used to transmit the rotational power of the driver to the drive shaft.

[0014] In some embodiments, the torque converter further includes a support block located between the first side plate and the second side plate, with both ends of the support block connected to the first side plate and the second side plate, respectively.

[0015] In some embodiments, the torque converter further includes a lifting ring connected to the support block.

[0016] The beneficial effects of this application are as follows: the transmission system composed of the driving sprocket, the driven sprocket and the chain can smoothly convert the high-speed rotation power of the driver into the torque output of the driven sprocket, thereby driving the bolt to rotate, thus realizing the tightening or loosening of the bolt, improving the operating efficiency of the bolt in the curtain wall system, and ensuring the consistency and reliability of the bolt preload, reducing the risk of loosening or failure of the curtain wall structure due to insufficient preload.

[0025] Please see Figures 1 to 3 This application provides a torque converter 100, which can be used to tighten bolts 101, thereby connecting the columns and beams in the curtain wall system.

[0026] The torque converter 100 includes: a first side plate 11, a second side plate 12, a positioning block 24, a drive sprocket 23, a driven sprocket 22, a chain 21, and a driver. The driver can be an electric motor and can be detachably connected to the drive sprocket 23 for transmission, thereby transmitting the rotational power of the driver to the drive sprocket 23. The first side plate 11, the second side plate 12, and the positioning block 24 can be made of metal, such as aluminum alloy. Aluminum alloy has a density of 2.63–2.85 g / cm³, high strength (specific strength close to that of high-alloy steel), higher specific stiffness than steel, good casting and plastic processing properties, and good corrosion resistance, making it suitable for use as a structural material.

[0027] Please see Figures 1 to 3 The first side plate 11 and the second side plate 12 are elongated and arranged opposite each other. The elongated first side plate 11 and the second side plate 12 have basically the same shape, so that they can be inserted into the narrow working space to tighten the bolt 101.

[0028] The driving sprocket 23 and the driven sprocket 22 are both located between the first side plate 11 and the second side plate 12. The two ends of the driving sprocket 23 are rotatably connected to one end of the first side plate 11 and one end of the second side plate 12, respectively. The two ends of the driven sprocket 22 are rotatably connected to the other end of the first side plate 11 and the other end of the second side plate 12, respectively. That is, the driving sprocket 23 and the driven sprocket 22 are arranged at intervals along the length direction of the first side plate 11 or the second side plate 12.

[0029] Please see Figures 1 to 3 The chain 21 has its two ends engaged with the driving sprocket 23 and the driven sprocket 22, respectively. A positioning block 24 is located between the first side plate 11 and the second side plate 12, and its two ends are connected to both the first side plate 11 and the second side plate 12. Two positioning blocks 24 are spaced apart along the length of either the first side plate 11 or the second side plate 12. The driver is used to drive the driving sprocket 23 to rotate. The positioning block 24 ensures a stable connection between the first side plate 11 and the second side plate 12, giving the torque converter 100 sufficient structural strength.

[0030] Please see Figures 1 to 3 In this embodiment, the transmission system consisting of the driving sprocket 23, the driven sprocket 22, and the chain 21 can smoothly convert the high-speed rotational power of the driver into the torque output of the driven sprocket 22, thereby causing the driving sprocket to drive the bolt 101 to rotate, thus achieving the tightening or loosening of the bolt 101, improving the operating efficiency of the bolt 101 in the curtain wall system, and ensuring the consistency and reliability of the preload of the bolt 101, reducing the risk of loosening or failure of the curtain wall structure due to insufficient preload.

[0031] Compared to traditional manual wrench operation, the torque converter 100 reduces the physical exertion of construction workers, saving time and labor costs, especially in high-rise curtain wall construction. The spaced positioning blocks 24 enhance the structural rigidity of the first side plate 11 and the second side plate 12, preventing deformation of the side plates under high torque and ensuring the stability of the transmission system. Furthermore, the elongated design of the first side plate 11 and the second side plate 12 makes the torque converter 100 compact, facilitating its use in the confined construction space of the curtain wall system.

[0032] Please see Figures 1 to 3 In some embodiments, the two positioning blocks 24 are located between the driving sprocket 23 and the driven sprocket 22 along the length direction of the first side plate 11 or the second side plate 12.

[0033] Optionally, the positioning block 24 is located in the middle area between the sprockets, which can more evenly distribute the tension and lateral stress generated during the transmission of the chain 21, avoiding local deformation or vibration of the side plate caused by the high-speed rotation of the chain 21, thereby improving the overall structural rigidity and durability of the torque converter 100. Tightening the bolts 101 requires a stable torque output; the positioning block 24 effectively reduces power loss during transmission, ensuring that the torque output by the driven sprocket 22 is accurate and continuous.

[0034] Please see Figures 1 to 3 In some embodiments, multiple chains 21 are arranged at intervals, and each chain 21 meshes with the driving sprocket 23 and the driven sprocket 22.

[0035] Optionally, the arrangement of multiple chains 21 increases the power transmission contact points between the driving sprocket 23 and the driven sprocket 22, disperses the force on a single chain 21, and reduces the risk of chain 21 breaking or losing teeth due to high torque, thereby improving the reliability and service life of the transmission system.

[0036] During the tightening of bolts 101 in the curtain wall system, bolts 101 often require a large preload to ensure the stability of the connection between the beams and columns. The coordinated transmission of multiple chains 21 can provide a larger torque output to meet the tightening requirements of high-strength bolts 101, while reducing construction interruptions caused by transmission failure.

[0037] Please see Figures 1 to 3 In some embodiments, the first side plate 11 is provided with a positioning through hole 111, and the positioning block 24 is provided with a positioning threaded hole 243 at the position where it connects to the first side plate 11. The first side plate 11 is provided with a positioning through hole 111 at the position corresponding to the positioning threaded hole 243. The torque converter 100 also includes a positioning bolt 25, one end of which passes through the positioning through hole 111 and is screwed into the positioning threaded hole 243.

[0038] Optionally, the positioning block 24 and the first side plate 11 are firmly connected by the positioning bolt 25 and the positioning threaded hole 243, which enhances the overall structural strength of the torque converter 100. The positioning threaded hole 243 is arranged in two at intervals along the length direction of the first side plate 11 or the second side plate 12, and the positioning bolt 25 is screwed into each positioning threaded hole 243.

[0039] Please see Figures 1 to 3 When the high-strength bolts 101 are tightened, the first side plate 11 and the second side plate 12 can withstand a large reaction force, avoiding the problem of the positioning block 24 loosening or the side plate deforming. The threaded connection between the positioning bolts 25 and the positioning threaded holes 243 also facilitates the installation and disassembly of the positioning block 24, making it more convenient for the torque converter 100 to be maintained or replaced when necessary, and reducing the maintenance difficulty on the construction site.

[0040] Please see Figures 1 to 3 In some embodiments, the surface of the first side plate 11 facing the positioning block 24 is further provided with a limiting cavity 112, the positioning through hole 111 is provided at the bottom of the limiting cavity 112, the positioning block 24 is provided with a limiting part 241 protruding into the limiting cavity 112, and the positioning threaded hole 243 is at least partially located in the limiting part 241.

[0041] Optionally, the fitting structure of the limiting cavity 112 and the limiting part 241 improves the connection stability and alignment accuracy between the positioning block 24 and the first side plate 11. After the limiting part 241 is embedded in the limiting cavity 112, it can effectively limit the displacement or rotation of the positioning block 24 under lateral force or high torque, thereby enhancing the deformation resistance of the torque converter 100 when tightening the bolt 101. The positioning through hole 111 and the positioning threaded hole 243 are respectively provided in the limiting cavity 112 and the limiting part 241, which optimizes the force distribution, reduces the stress concentration at the connection of the positioning bolt 25, and improves the reliability of the connection.

[0042] Please see Figures 1 to 3 In some embodiments, the second side plate 12 is provided with a positioning groove 121, and the positioning block 24 is provided with a positioning part 242 protruding into the positioning groove 121.

[0043] Optionally, the positioning part 242 can be riveted into the positioning groove 121 to enhance the connection stability between the positioning block 24 and the second side plate 12. After the positioning part 242 is embedded in the positioning groove 121, it can effectively limit the displacement of the positioning block 24 under lateral force or vibration, and ensure the overall rigidity of the torque converter 100 when tightening the bolt 101 under high load.

[0044] The design of the positioning groove 121 also improves the installation accuracy of the positioning block 24, reduces the instability of the transmission system caused by alignment errors, thereby ensuring the stability and accuracy of the output torque of the driven sprocket 22 and meeting the high consistency requirement of the preload of the bolt 101.

[0045] Of course, a positioning threaded hole 243 can also be opened on the positioning part 242, and a positioning through hole 111 can be opened on the second side plate 12 at the position corresponding to the positioning threaded hole 243 of the positioning part 242, so as to connect the positioning block 24 and the second side plate 12 by screwing the positioning bolt 25 into the positioning threaded hole 243.

[0046] Please see Figures 1 to 3 In some embodiments, the driven sprocket 22 includes a driven shaft 221, driven teeth 222 disposed on the side surface of the driven shaft 221, and a drive head 223 located at one end of the driven shaft 221. The two ends of the driven shaft 221 are rotatably connected to the first side plate 11 and the second side plate 12, respectively. The driven teeth 222 are arranged in a plurality of circumferentially spaced around the driven shaft 221.

[0047] Optionally, in this embodiment, three chains 21 are provided, and each chain 21 is provided with a ring of driven teeth 222. The multi-point meshing structure between the driven teeth 222 and the chain 21 ensures the smoothness and reliability of the chain 21 transmission, reduces the risk of chain 21 slippage or tooth derailment, and thus ensures efficient power transmission.

[0048] The drive head 223 is adapted to the bolt 101 that needs to be tightened. The end of the bolt 101 is provided with a drive cavity. The drive head 223 is partially inserted into the drive cavity to drive the bolt 101 to rotate, converting the torque transmitted by the chain 21 into tightening force, improving the uniformity and stability of the preload of the bolt 101, solving the problem of insufficient preload in traditional manual tightening, and finally achieving the tightening or loosening of the bolt 101.

[0049] Please see Figures 1 to 3 In some embodiments, the drive sprocket 23 includes a drive shaft 231, drive teeth 232 disposed on the side surface of the drive shaft 231, and a transmission sleeve 233 connected to one end of the drive shaft 231. The two ends of the drive shaft 231 are rotatably connected to the first side plate 11 and the second side plate 12, respectively. Multiple drive teeth 232 are arranged circumferentially around the drive shaft 231. The transmission sleeve 233 is used to transmit the rotational power of the driver to the drive shaft 231.

[0050] Similarly, each chain 21 is provided with a corresponding ring of driving teeth 232. The circumferential multi-point meshing structure of the driving teeth 232 ensures the smoothness of chain 21 transmission and high efficiency of power transmission, avoiding slippage or interruption during power transmission, thereby providing a stable torque output to the driven sprocket 22. One end of the transmission sleeve 233 is sleeved and driven to the driving shaft 231, and the other end of the rotating sleeve is driven to the output shaft of the driver, so that the driver can drive the driving shaft 231 to rotate.

[0051] Please see Figures 1 to 3 In some embodiments, the torque converter 100 further includes a support block 103 located between the first side plate 11 and the second side plate 12, with the two ends of the support block 103 connected to the first side plate 11 and the second side plate 12, respectively.

[0052] Optionally, the two ends of the support block 103 can also be screwed to the first side plate 11 and the second side plate 12 respectively by positioning bolts 25. The support block 103 enhances the overall structural rigidity and deformation resistance of the torque converter 100. When the high-strength bolts 101 are tightened, the support block 103 can effectively disperse the high torque reaction force borne by the first side plate 11 and the second side plate 12, preventing the first side plate 11 and the second side plate 12 from bending or deforming. The support block 103 also improves the durability of the torque converter 100, enabling it to maintain stable performance during long-term high-load operation and extending its service life.

[0053] Please see Figures 1 to 3 In some embodiments, the torque converter 100 further includes a lifting ring 102 connected to the support block 103.

[0054] Optionally, the lifting ring 102 enhances the portability and ease of carrying of the torque converter 100 on the construction site. Construction workers can easily move or suspend tools using the lifting ring 102, especially in high-rise building curtain wall construction. The lifting ring 102 facilitates securing tools to safety ropes or construction platforms, reducing the risk of the torque converter 100 slipping and improving operational safety. Simultaneously, the lifting ring 102, connected to the support block 103, makes the stress point more stable, avoiding adverse effects on the side plates or transmission system during lifting and protecting the core functional components of the torque converter 100.

[0055] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
