Description

Technical Field

[0001] This invention relates to the field of buckle adjustment technology, and in particular to a buckle tensioning and adjusting device and buckle system. Background Technology

[0002] Cable-stayed arch bridge construction using the inclined cable-stayed method is one of the main construction methods for arch bridges. According to statistics, about 70% of the existing arch bridges in my country are constructed using cable-stayed methods. The construction process involves first prefabricating the arch ring in sections, then using a cable crane to lift them into place, and temporarily securing them with inclined cable-stayed anchors until the arch ribs are closed to form the arch ring, thus balancing the self-weight of the arch ribs and the overturning moment. During the temporary anchoring of the arch ribs with inclined cable-stayed anchors, the cable tension of a single anchor cable is different when installing different arch sections, so the cable tension needs to be adjusted.

[0003] For example, Chinese patent "CN106812070B" discloses a "cable tensioning device for cable hoisting construction of arch bridges using an inclined cable-stayed method." This device adjusts the relative length of the anchor cable by rotating a three-pronged wrench to adjust the relative position of the sliding tensioning rack and the fixed sliding groove base, thereby adjusting the cable force. However, in practice, it has been found that manually adjusting the anchor cable requires overcoming the anchor cable stress, which causes the position to change after adjustment and braking, resulting in low accuracy. Furthermore, the anchor cable stress can cause the three-pronged wrench to reverse, which is quite dangerous. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cable tensioning and adjustment device and a fastening system. This solves the problems of existing technologies where adjusting anchor cables manually requires overcoming the stress of the anchor cables, which leads to changes in position after cable force adjustment and braking, resulting in low accuracy. Furthermore, the stress of the anchor cables can cause the three-pronged wrench to reverse, which is quite dangerous.

[0005] According to embodiments of the present invention, the present invention adopts the following technical solution:

[0006] A cable tensioning adjustment device, installed on an arch rib and used for installing anchor cables, includes:

[0007] The fixed cylinder has a channel open at one end, and several toothed grooves are provided on both sides of the channel;

[0008] A fixed plate is attached to one end of an anchor cable, and the other end of the fixed plate is slidably positioned in the channel.

[0009] A fastener, located at the end of the fixed cylinder and connected to the arch rib; and

[0010] The fixing unit includes a locking block that passes through the side of the fixing plate and corresponds to the tooth groove, and a pressing member disposed in the fixing plate. The pressing member is connected to the locking block and is used to drive the locking block to engage with the corresponding tooth groove.

[0011] Both the locking block and the tooth groove have guide slopes and limiting planes. When the locking block is engaged in the tooth groove, the two limiting planes fit together.

[0012] Preferably, the extrusion component includes a plurality of mounting rods disposed within a fixed plate and two mounting plates slidably disposed on the plurality of mounting rods. The two mounting plates are respectively connected to locking blocks on both sides of the fixed plate. Each of the plurality of mounting rods is fitted with a spring, and the spring abuts against the end of the mounting plate away from the locking block.

[0013] Preferably, the fixed cylinder has a fixed seat at the end near the anchor cable, the fixed plate has an installation seat at the end away from the anchor cable, and a jack is provided between the fixed seat and the installation seat.

[0014] Preferably, the fixing unit further includes two adjusting rods rotatably connected to the two mounting plates respectively, and an adjusting block rotatably connected to the two adjusting rods, with the adjusting block slidably connected to the inner side of the fixing plate.

[0015] Preferably, a lever is provided on the outer side of the fixed plate, and the lever is connected to the adjusting block.

[0016] Preferably, the fixing element includes a threaded cylinder disposed on the arch rib and a threaded post disposed at the end of the fixing cylinder, the threaded post being threadedly connected to the inside of the threaded cylinder.

[0017] Preferably, a second connecting seat is fixedly provided at the end of the fixed cylinder, and a first connecting seat is fixedly provided at the end of the threaded column. The first connecting seat and the second connecting seat are movably connected by a rotating shaft.

[0019] According to embodiments of the present invention, the present invention also employs the following technical solutions:

[0020] A fastening system includes a fastening tower and an anchoring system, and also includes the aforementioned cable tensioning and adjustment device.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In this design, after the fasteners and anchor cables are installed onto the arch rib and the fixing plate respectively, the anchor cables can be quickly installed onto the arch rib, thus fixing the ends of the anchor cables. When adjusting the cable tension, the fixing plate is continuously pushed forward, moving within the channel of the fixing cylinder. With the cooperation of the locking block and the tooth groove, the limiting plane of the locking block and the limiting plane of the tooth groove are aligned, preventing the fixing plate from moving in the opposite direction of the push. This allows the fixing plate to bear the stress of the anchor cable, improving safety. At the same time, the locking block and the tooth groove can guide each other through their guide ramps. During the continuous push of the fixing plate, the fixing plate, with the cooperation of the pressing component, can drive the locking block to move in each tooth groove, enabling precise adjustment of the anchor cable tension. Multiple locking positions can be provided through each tooth groove, ensuring the safety and stability of the arch rib and reducing safety hazards caused by insufficient or excessive tension. Furthermore, when the fixing plate stops moving, it can be securely locked to ensure the adjusted tension. Attached Figure Description

[0031] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 3 As shown, this embodiment of the invention proposes a cable tensioning and adjustment device, installed on the arch rib 1 and used to install the anchor cable 2, comprising:

[0033] The fixed cylinder 3 has a channel with an opening at one end, and several toothed grooves 302 are provided on both sides of the channel;

[0034] The fixing plate 4 and the anchor cable 2 are installed at one end of the fixing plate 4, and the other end of the fixing plate 4 is slidably disposed in the channel;

[0035] Fixing member 5 is located at the end of fixing cylinder 3 and connected to arch rib 1; and

[0036] The fixing unit includes a locking block 601 that passes through the side of the fixing plate 4 and corresponds to the tooth groove 302, and a pressing member disposed in the fixing plate 4. The pressing member is connected to the locking block 601 and is used to drive the locking block 601 to engage in the corresponding tooth groove 302.

[0037] Both the locking block 601 and the tooth groove 302 have a guide slope 6010 and a limiting plane 6011. When the locking block 601 is engaged in the tooth groove 302, the two limiting planes 6011 fit together.

[0038] In the embodiments of the present invention, when the arch rib 1 is prefabricated in sections, the fixing member 5 can be anchored to the arch rib 1 first. After the arch rib 1 is installed, the anchor cable 2 is installed to the fixing plate 4 to form a preliminary installation structure between the anchor cable 2 and the arch rib 1. The anchor cable 2 can be quickly installed on the arch rib 1 to fix the end of the anchor cable 2.

[0039] To ensure the accuracy of the arch rib 1 installation and adjust the cable force of the anchor cable 2, the fixing plate 4 is continuously advanced, moving within the channel of the fixing cylinder 3. This shortens the overall length of the fixing cylinder 3 and the fixing plate 4, reducing the distance between the end of the anchor cable 2 and the arch rib 1. With the cooperation of the locking block 601 and the toothed groove 302, the limiting plane 6011 of the locking block 601 and the limiting plane 6011 of the toothed groove 302 are aligned, preventing the fixing plate 4 from moving in the opposite direction of advancement. This allows it to bear the stress of the anchor cable 2, improving safety. Furthermore, as the fixing plate 4 continues to be advanced, the locking block 601 and the toothed groove 302 can communicate through their... The guide ramps 6010 guide each other, allowing the fixed plate 4 to have a springback stroke under the cooperation of the extrusion parts during the continuous advancement of the fixed plate 4. This continuous springback drives the locking block 601 to move in each tooth groove 302, enabling precise adjustment of the anchor cable 2 tension. The tooth groove 302 provides multiple locking positions, ensuring the safety and stability of the arch rib 1 and reducing safety hazards caused by insufficient or excessive tension. When the fixed plate 4 stops moving, the limiting plane 6011 of the locking block 601 fits with the limiting plane 6011 of the tooth groove 302, achieving a stable lock and ensuring the adjusted tension.

[0040] Based on the above solutions, such as Figures 4 to 6 As shown, the extrusion component includes a plurality of mounting rods 605 disposed within the fixed plate 4 and two mounting plates 6 slidably disposed on the plurality of mounting rods 605. The two mounting plates 6 are respectively connected to locking blocks 601 on both sides of the fixed plate 4. Each of the plurality of mounting rods 605 is fitted with a spring 602, and the spring 602 abuts against the end of the mounting plate 6 away from the locking block 601.

[0041] Specifically, when the locking block 601 moves and self-locks within the toothed groove 302 through the cooperation of the extrusion components, to facilitate the installation of the end of the anchor cable 2 at the end of the fixing plate 4, the fixing plate 4 is initially positioned at the end of the fixing cylinder 3, and the locking block 601 is located in the outermost toothed groove 302 within the channel, maximizing the overall length of the fixing cylinder 3 and the fixing plate 4. Subsequently, when adjusting the tension of the anchor cable 2, the fixing plate 4 within the fixing cylinder 3 is moved, causing the fixing plate 4 to exert a force on the locking block 601 along the length direction of the fixing plate 4. See Figure 5When the locking block 601 is engaged in the toothed groove 302, the guide slope 6010 of the locking block 601 fits against the guide slope 6010 of the toothed groove 302. After the locking block 601 is subjected to force, it cannot move due to the fixed structure of the toothed groove 302. Therefore, after being guided by the guide slope 6010, the locking block 601 will drive the mounting plate 6 it is mounted on to move into the fixed plate 4, thereby causing the mounting plate 6 to compress the spring 602 on one side and deform the spring 602. When the spring 602 is subjected to the maximum compressive force, the intersection point of the guide slope 6010 and the limiting plane 6011 in the locking block 601 (the tip of the locking block 601) corresponds exactly to the position between the two toothed grooves 302. When pushed forward, the locking block 601 aligns perfectly with the next tooth groove 302, thus releasing the pressure on the spring 602. The spring 602 returns to its original position, rebounding the force onto the mounting plate 6. This causes the mounting plate 6 to push the locking block 601 protruding again from the side of the fixing plate 4 and engaging with the corresponding tooth groove 302. This engagement also ensures that the limiting plane 6011 of the locking block 601 fits against the limiting plane 6011 of the tooth groove 302. With the planes in contact, the fixing plate 4 will not move in the opposite direction, achieving self-locking. The entire process only requires pushing the fixing plate 4 forward to tighten the anchor cable 2. The tightened anchor cable 2 will not retract due to its own stress, ensuring the accuracy of the adjusted anchor cable 2.

[0042] Specifically, such as Figure 2 As shown, a fixing seat 301 is provided at one end of the fixing cylinder 3 near the anchor cable 2, and an mounting seat 401 is provided at the other end of the fixing plate 4 away from the anchor cable 2. A jack 7 is provided between the fixing seat 301 and the mounting seat 401.

[0043] To facilitate the advancement of the fixing plate 4, a fixing seat 301 is installed at the end of the fixing cylinder 3 near the anchor cable 2. The installation method can be bolt connection or welding. A mounting seat 401 is installed at the end of the fixing plate 4 away from the anchor cable 2. The installation method can be welding. When the fixing seat 301 is bolted to the fixing cylinder 3, the groove of the fixing cylinder 3 can be an open structure, which facilitates the disassembly between the fixing plate 4 and the fixing cylinder 3. When the fixing seat 301 is welded to the fixing cylinder 3, the groove of the fixing cylinder 3 is a closed structure, making the fixing plate 4 and the fixing cylinder 3 a whole.

[0044] After the fixing plate 4 is pushed into the fixing cylinder 3, there is a certain distance between the mounting base 401 of the fixing plate 4 and the fixing base 301 of the fixing cylinder 3. This distance allows the jack 7 used for lifting to be installed. When the telescopic end of the jack 7 extends, the distance between the mounting base 401 and the fixing base 301 increases, thereby enabling the fixing plate 4 to be pushed forward. After the cable force value is adjusted, the telescopic end of the jack 7 can be retracted, thereby removing the jack 7 for subsequent use. In addition, a through hole can be opened in the fixing base 301, and the jack 7 can be fixedly installed on the fixing base 301 with bolts to ensure stability during use and prevent it from falling and affecting normal operation.

[0045] Based on the above solutions, such as Figure 5 and Figure 6 As shown, the fixing unit also includes two adjusting rods 603 that are rotatably connected to the two mounting plates 6 respectively, and an adjusting block 604 that is rotatably connected to the two adjusting rods 603. The adjusting block 604 is slidably connected to the inner side of the fixing plate 4.

[0046] After the temporary latching is completed, the lock block 601 can be adjusted to gradually complete the disassembly. Specifically, during operation, the following steps should be taken: Figure 4 For example, by moving the adjusting block 604 downward, the adjusting block 604 pulls the two adjusting rods 603 simultaneously. Since the ends of the adjusting rods 603 are movably connected to the mounting plate 6, and the mounting plate 6 is limited by the mounting rod 605 and can only slide along the direction of the mounting rod 605, when the adjusting block 604 is moved downward, the included angle between the two adjusting rods 603 becomes smaller, thereby reducing the distance between the two mounting plates 6. This causes the mounting plate 6 to move its locking block 601 away from the corresponding tooth groove 302, and allows the locking block 601 to be stored in the fixing plate 4, releasing the restriction on the fixing plate 4 in the fixing cylinder 3. Finally, the fixing plate 4 can be moved to the initial position for easy disassembly.

[0047] In other uses, if adjusting the fixing plate 4 causes the arch rib 1 to be over-tensioned, the position of the locking block 601 can also be adjusted through the above steps. After adjustment, simply loosen the adjusting block 604, and the locking block 601 can be snapped back into the corresponding tooth groove 302 under the action of the mounting plate 6 and the spring 602, thus achieving quick adjustment.

[0048] Specifically, such as Figure 6 As shown, a lever 606 is provided on the outer side of the fixed plate 4, and the lever 606 is connected to the adjusting block 604; under the action of the lever 606, it is convenient to manually adjust the adjusting block 604, making the operation more convenient.

[0049] Based on the above solutions, such as Figure 3 and Figure 4As shown, the fixing member 5 includes a threaded cylinder 501 disposed on the arch rib 1 and a threaded post 502 disposed at the end of the fixing cylinder 3. The threaded post 502 is threadedly connected to the inside of the threaded cylinder 501.

[0050] During the prefabrication of the arch rib 1, holes for installing the threaded cylinder 501 can be reserved, or the threaded cylinder 501 can be directly anchored in the arch rib 1 during prefabrication. When installing the arch rib 1, the threaded cylinder 501 can be installed first, and then the threaded post 502 at the end of the fixing cylinder 3 can be threaded into the threaded cylinder 501 to achieve quick fixation. Moreover, a second connecting seat 504 is fixedly provided at the end of the fixing cylinder 3, and a first connecting seat 503 is fixedly provided at the end of the threaded post 502. The first connecting seat 503 and the second connecting seat 504 are movably connected by a rotating shaft. Under the action of the first connecting seat 503 and the second connecting seat 504, the connection between the fixing cylinder 3 and the fixing member 5 can rotate. When the angle of the anchor cable 2 changes, the first connecting seat 503 and the second connecting seat 504 can change their angles automatically to ensure the stability of the fastening system.

[0051] Furthermore, a guide ball 505 is rotatably provided inside the second connecting seat 504, and the rotating shaft of the first connecting seat 503 passes through the guide ball 505. The guide ball 505 can rotate in multiple directions in the second connecting seat 504. When swaying occurs during the adjustment or installation of the anchor cable 2, in order to avoid unnecessary friction and ensure the stability of the structure, the fixing cylinder 3 can move in multiple directions through the guide ball 505, so that the fixed part 5 after installation is not affected, thereby ensuring the overall stability.

[0052] like Figure 7 As shown, this embodiment of the invention also proposes a fastening system, including a fastening tower 8 and an anchoring system 9, and also includes the above-mentioned fastening cable tensioning adjustment device. The specific structure of the fastening cable tensioning adjustment device is as described in the above embodiment. Since this fastening system adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
