Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and in particular to a fixing device for stable and high-precision loading of C-shaped steel mesh. Background Technology

[0002] The modularization of steel reinforcement in bridge towers is a trend in the construction of ultra-high concrete bridge towers. The main tower construction of the Shenzhen-Zhongshan Bridge and the Longtan Yangtze River Bridge projects both adopted a modular steel reinforcement construction process based on mesh assembly, achieving industrialization, automation, and intelligent upgrading of bridge tower steel reinforcement construction. The modular steel reinforcement construction process is as follows: mechanized processing of steel mesh at a centralized steel reinforcement distribution center → loading and transportation of mesh to the construction site → manual assembly → hoisting onto the tower → component installation → formwork construction → concrete construction. This greatly improves the accuracy of steel reinforcement binding and forming, increases work efficiency, reduces the number of workers, and achieves inherent safety. The formed steel mesh is generally C-shaped, characterized by its heavy weight, large size, and high flexibility. The mesh must be securely fixed during loading; otherwise, the C-shaped steel mesh is easily damaged during transportation, leading to safety accidents.

[0014] In the preferred embodiment, the support frame and the adjustment frame are respectively provided with a first mounting slot and a second mounting slot.

[0015] The beneficial effects of this invention are as follows: By manufacturing a support frame and an adjustment frame, it can be conveniently and stably installed on the cantilever plate of a transport vehicle.

Simultaneously, a second fixing component and a first fixing component are respectively provided on the support frame and the adjustment frame, which can fully lock the transverse and vertical bars according to the structural characteristics of the C-shaped steel mesh, thereby ensuring that the C-shaped steel mesh is fully fixed and its degree of freedom is completely restricted. Furthermore, the second fixing component and the first fixing component can be adjusted according to the mesh size of different C-shaped steel meshes, improving the overall adaptability. In addition, a safety component is also provided on the support frame. This design further improves the fixing effect of the C-shaped steel mesh, providing a systematic safety and error-proofing effect. The notches under the support frame and adjustment frame correspond to the reference plate. Since it is difficult to ensure the flatness of the bearing surface of the transport vehicle during long-term use, the reference plate can use the stability of the cantilever plate position as the reference for the installation of the C-shaped steel mesh, thereby avoiding the problem of reduced installation locking accuracy caused by the unevenness of the transport vehicle's bearing surface. The design is ingenious. At the same time, a calibration component is set on the outside of the second fixing component, which can play a role in measuring accuracy and correcting deviation during the hoisting and lowering of the C-shaped steel mesh into the transport vehicle, improving the overall hoisting efficiency and ensuring the quality of hoisting.

Detailed Implementation

[0018] like Figure 1-9 In the present invention, a fixing device for stable and high-precision loading of C-shaped steel mesh includes a support frame 1 and an adjustment frame 2 mounted on a transport vehicle 6. The support frame 1 and the adjustment frame 2 are connected to form a clamping area 5 for fixing and constraining the C-shaped steel mesh 8. The C-shaped steel mesh 8 includes a plurality of mutually perpendicularly arranged transverse bars 801 and vertical bars 802. The support frame 1 and the adjustment frame 2 are respectively provided with a second fixing component 15 and a first fixing component 14. The second fixing component 15 includes a bottom support head 1503, and the first fixing component 14 includes a vertical plate 1407. The bottom support head 1503 is supported on the lower part of the transverse bars 801, and the vertical plate 1407 abuts against the outside of the vertical bars 802. In use, the steel bars are first mechanically processed according to the design specifications and quantity at the centralized steel bar distribution center (i.e., the processing plant), and then installed on the transport vehicle 6. Simultaneously, multiple support frames 1 and adjustment frames 2 are fabricated. An appropriate number of support frames 1 and adjustment frames 2 are installed according to the length of the C-shaped steel mesh 8. The transport vehicle 6, in conjunction with the support frames 1 and adjustment frames 2, is equipped with cantilever plates 601 and locking holes 602. Before transportation, the position of the support frames 1 is adjusted according to the specifications of the C-shaped steel mesh 8 to be transported. During use, the support frames 1 are first installed on the transport vehicle 6. To ensure that the axes of the support frames 1 and adjustment frames 2 are aligned, bolts 3 and nuts 4 are used to secure the support frames 1 and adjustment frames 2. Pre-assemble the entire assembly onto the transport vehicle 6, and then fully fix the support frame 1. Since the same type of C-shaped steel mesh 8 is formed by the cooperation of multiple horizontal bars 801 and multiple vertical bars 802, the size of its mesh is uniform. The vertical plate 1407 on the first fixing component 14 first completes the fitting of the vertical bars 802, and then moves the adjustment frame 2 directly opposite the support frame 1 to change the angle of the bottom support head 1503 on the second fixing component 15, supporting the horizontal bars 801 from inside the mesh. After adjustment, the support frame 1 and the adjustment frame 2 are fully locked, thereby completing the fixing of the C-shaped steel mesh 8. The overall operation is convenient and the effect is good.

[0019] like Figure 10-14In the preferred embodiment, the support frame 1 includes two triangular plates 101 arranged opposite each other, which are connected by a first connecting plate 102 and a second connecting plate 103. A third telescopic cylinder 19 is detachably provided on the second connecting plate 103. The third telescopic cylinder 19 is hinged to the second fixing component 15. The third telescopic cylinder 19 is used to change the state of the second fixing component 15 on the support frame 1. The adjustment frame 2 includes two L-shaped plates 201 arranged opposite each other, which are connected by a third connecting plate 210. The support frame 1 and the adjustment frame 2 are connected by bolts 3 and nuts 4. A second slot 1504 is provided on the bottom support head 1503, and a first slot 1412 is provided on the vertical plate 1407. The bottom of the support frame 1 and the adjustment frame 2 are respectively provided with a matching notch 113 and a reference plate 206. The reference plate 206 is used to support the C-shaped steel mesh 8. The first slot 1412 and the second slot 1504 adopt arc grooves or V-shaped grooves to ensure sufficient restriction of the freedom of the transverse reinforcement 801 and the vertical reinforcement 802. The support frame 1 and the adjustment frame 2 adopt a hollow structure to ensure the overall structural strength while reducing their own weight. At the same time, it is convenient to install the second fixing component 15 and the first fixing component 14. The appearance is flat and easy to use. Since it is difficult to ensure the flatness of the surface on which the transport vehicle 6 is mounted during long-term use, the reference plate can use the stability of the cantilever plate position as the reference for the installation of the C-shaped steel mesh. This avoids the problem of reduced installation locking accuracy caused by the unevenness of the transport vehicle bearing surface. After sufficient fixation, it can also reduce the problem of insufficient overall constraint of the C-shaped steel mesh 8 due to vibration caused by road undulations during transportation, resulting in an unstable overall state.

[0020] In a preferred embodiment, a calibration component 13 is detachably provided on the outer side of the triangular plate 101. The triangular plate 101 is provided with a first fixing hole 106. The calibration component 13 includes a sleeve 1301 and a sliding rod 1302. The sliding rod 1302 and the sleeve 1301 are slidably connected. A baffle 1303 is provided on the outer side of the sliding rod 1302. The baffle 1303 abuts against the inner side of the transverse rib 801. A connector 1304 is provided at the end of the sleeve 1301. The connector 1304 is threadedly connected to the first fixing hole 106. A plurality of bolts 3 are threadedly connected to the sleeve 1301. The bolts 3 are used to lock the sliding rod 1302. During use, according to the specifications and dimensions of the C-shaped steel mesh 8, release the bolt 3 from the locking of the slide rod 1302, remove the slide rod 1302, and adjust the position of the baffle 1303. The baffle 1303 serves as a marker point during the hoisting of the C-shaped steel mesh 8, facilitating manual adjustment and correction. After the bottom of the C-shaped steel mesh 8 slowly approaches the baffle 1303 and then lowers below the baffle 1303, the positions of both sides of the C-shaped steel mesh 8 are fully limited, and it descends along the outer side of the baffle 1303, finally entering the holding area 5. The overall operation is simple, ensuring accuracy and efficiency during lowering.

[0021] In the preferred embodiment, the support frame 1 and the adjustment frame 2 are respectively provided with a first pair of positioning seats 104 and a second pair of positioning seats 203 on both sides. The first pair of positioning seats 104 has a second fixing hole 108 through it, and the second pair of positioning seats 203 has a sixth fixing hole 204 through it. Bolts 3 are inserted into the second fixing hole 108 and the sixth fixing hole 204. The bolts 3 are provided with multiple nuts 4. A first telescopic cylinder 12 is also provided. The first telescopic cylinder 12 includes a first cylinder body 1201 and a first push rod 1202. The first cylinder body 1201 is fixed by the first mounting seat 1203 and the first pair of positioning seats 104, and the first push rod 1202 is fixed by the synchronization plate 1204 and the second pair of positioning seats 203. This structure allows for the initial locking of the support frame 1 and the adjusting frame 2 using bolts 3 and nuts 4, completing the pre-assembly of the support frame 1 and the adjusting frame 2. Then, it is installed onto the transport vehicle 6. This ensures that the movement directions of the support frame 1 and the adjusting frame 2 are coaxial, facilitating subsequent clamping and precision. The locking of the nuts 4 on the adjusting frame 2 near the support frame 1 is then released for easier subsequent operation. The first pair of positioning seats 104 and the second pair of positioning seats 203 increase the contact area between the support frame 1 and the adjusting frame 2 and the load-bearing surface of the transport vehicle 6, resulting in more sufficient overall force distribution and better load-bearing capacity. Simultaneously, their mutual cooperation provides guidance and limiting functions. After adjustment, the first telescopic cylinder 12 is installed, enabling the fixing device to simultaneously operate in both automatic and manual modes, providing backup for each other and improving its ability to cope with changes in the external environment. The first telescopic cylinder 12 is easy to install and remove, and has low maintenance and operating costs.

[0022] In a preferred embodiment, the third telescopic cylinder 19 includes a third cylinder body 1901 and a third push rod 1902. The second fixing assembly 15 includes a top plate 1501. A drive seat 1516 is provided on the lower side of the top plate 1501. The third push rod 1902 and the drive seat 1516 are hinged together. A third mounting seat 1903 is provided at the end of the third cylinder body 1901. A base 1904 is hinged on the third mounting seat 1903. The base 1904 is fixed by a locking pin 17 and a second connecting plate 103. The bottom support head 1503 is detachably mounted on the follower head 1502. The two sides of the follower head 1502 are respectively hinged to the triangular plate 101 and the top plate 1501 by bolts 3 and nuts 4. The number of bottom support heads 1503 required for operation is adjusted as needed, while bottom support heads 1503 that may cause interference are removed to meet the supporting function of the transverse reinforcement 801. This structure allows the third telescopic cylinder 19 to change the angle of the follower head 1502 relative to the triangular plate 101, thereby switching between the avoidance retraction position and the working position. When the C-shaped steel mesh 8 is lowered and hoisted, the follower head 1502 is in the avoidance retraction position. When the C-shaped steel mesh 8 is lowered and approaches the support frame 1 to the design position, the follower head 1502 rotates and extends to switch to the working position to complete the support of the C-shaped steel mesh 8. It is convenient to use and has high operating efficiency.

[0023] In a preferred embodiment, a plurality of fifth fixing holes 111 are provided through the triangular plate 101, a first gap 114 is provided between the two triangular plates 101, the follower head 1502 is located in the first gap 114, a plurality of fifth through holes 1510 are provided through the top plate 1501, a sixth through hole 1511 and a seventh through hole 1512 are provided through the follower head 1502, a through groove 1513 is provided in the middle of the seventh through hole 1512, the top plate 1501 is located in the through groove 1513, a plurality of fourth fixing holes 110 and a third through hole 1505 are also provided through the upper sides of the triangular plate 101 and the top plate 1501 respectively, the insertion rod 1506 is inserted into the fourth fixing hole 110 and the third through hole 1505, a reinforcing block 1507 is provided at the bottom of the follower head 1502, and a plurality of stop rods 112 are also inserted on the triangular plate 101, the stop rods 112 are used to limit the angle of the follower head 1502. This structure ensures smooth and efficient rotation of the top plate 1501 and multiple follower heads 1502. Rubber bladders are provided on the first connecting plate 102 and the stop bar 112 at the top of the support frame 1. Preferably, to improve operational convenience, audible air bladders can be used, emitting a sound when the top plate 1501 or follower head 1502 compresses the rubber bladder, thus reminding the operator to ensure proper operation. The reinforcing block 1507 enhances the support effect on the bottom support head 1503, ensuring sufficient constraint on the transverse rib 801. When the top plate 1501 is at its highest position, the follower head 1503 is at its lowest position (non-working). (State), the insert rod 1506 fixes the top plate 1501. When the top plate 1501 is in the lowest position, the follower head 1503 is in the highest position (working state). The insert rod 1506 fixes the top plate 1501, ensuring that the second fixing component 15 is fully stressed in different states. Multiple stop rods 112 can be set as needed to make fine adjustments for different mesh sizes of C-shaped steel mesh 8. The stop rods 112 that cannot be accurately used are removed until the follower head 1503 rotates into place and fits against the stop rod 112. At this time, the follower head 1503 can fully support the transverse reinforcement 802.

[0024] In a preferred embodiment, the end of the follower head 1502 is provided with a first threaded hole 1514, and the end of the base head 1503 is provided with a second threaded rod 1515. The second threaded rod 1515 and the first threaded hole 1514 are threadedly connected. The lower side of the top plate 1501 is provided with symmetrical grooves 1508. A fourth through hole 1509 is provided through the groove 1508. The end of the drive seat 1516 is provided with a third ear plate 1517. The third ear plate 1517 is hinged to the third push rod 1902 by a pin 1520. A sliding groove 1518 is provided through the drive seat 1516. The top plate 1501 slides in the groove 1508. An eighth through hole 1519 is provided in the groove 1508. The pin 1520 passes through the eighth through hole 1519 and the fourth through hole 1509. This structure allows the position of the drive seat 1516 relative to the top plate 1501 to be changed as needed, thereby changing the drive response speed, ensuring better response and more efficient operation. At the same time, the length of the bottom support head 1503 can be changed as needed to meet the needs of different mesh lengths, resulting in better support.

[0025] like Figure 15-19 In the preferred embodiment, the vertical plate 1407 is connected by a first threaded rod 1409 and a bidirectional threaded sleeve 1401. The bidirectional threaded sleeve 1401 is rotatably mounted on the L-shaped plate 201 and is used to change the position of the vertical plate 1407.

[0026] like Figure 20-33In a preferred embodiment, the support frame 1 is detachably equipped with a safety component 16. The safety component 16 is connected to the support frame 1 via a second telescopic cylinder 18. The safety component 16 includes two opposing baffles 1601. A fourth ear plate 1602 is connected to both sides of the baffles 1601 via a transition plate 1606. Two hinge plates 107 are parallel to each other on the outer side of the triangular plate 101. A locking pin 17 passes through the hinge plates 107 and the fourth ear plates 1602. An extension plate 1603 and a vertical rod 1604 are provided on the transition plate 1606. The second telescopic cylinder 18 includes a second cylinder body 1801 and a second push rod 1802. A vertical rod 1604 passes through the second push rod 1802 and is fixed by a nut 4 and the second push rod 1802. A third fixing hole 109 is provided on the second connecting plate 103. A second mounting seat 1803 is provided at the end of the second push rod 1802. The second mounting seat 1803 is hinged by a fixing nail 20 and the third fixing hole 109. A rounded corner 1605 is also provided on the baffle 1601. The transition plate 1606 is inclined to the outside of the support frame 1. This structure allows the safety component 16 to be closed when the C-shaped steel mesh 8 is lowered. The safety component 16 provides a safety barrier for the follower head 1503, preventing the C-shaped steel mesh 8 from hitting the follower head 1503 due to movement and deflection during lowering. It also serves as a vertical guide and limiter. After the C-shaped steel mesh 8 is lowered into place on the base plate 206, the safety component 16 is opened by operating the second telescopic cylinder 18, exposing the follower head 1503. The position of the adjustment rod 2 is changed, thereby pushing the C-shaped steel mesh 8 closer to the support frame 1. The follower head 1503 rotates and fixes the transverse reinforcement 801 from the bottom. After the overall fixation is completed, the second telescopic cylinder 8 is operated again, and the second top rod 1802 extends. The baffle 1601 is attached to the transverse reinforcement 801. Since the baffle 1601 has rounded corners 1605, the friction and interference problems are reduced. At this time, the C-shaped steel mesh 8 is completely locked.

[0027] In the preferred embodiment, the support frame 1 and the adjustment frame 2 are respectively provided with a first mounting groove 105 and a second mounting groove 205. The transport vehicle 6 is symmetrically provided with multiple cantilever plates 601, and the cantilever plates 601 are provided with multiple locking holes 602. The support frame 1 and the adjustment frame 2 are respectively fixed to the cantilever plates 601 by bolts 3 and nuts 4. The transport vehicle 6 is also provided with a lifting device 7 and a sling 9 for hoisting the C-shaped steel mesh 8 into the clamping area 5. The transport vehicle 6 is also provided with a hand chain hoist 10 and a guy rope 11, which are used to fix the C-shaped steel mesh 8 after it is placed into the clamping area 5. Preferably, two locking holes 602 are provided to better ensure the installation accuracy of the support frame 1 and the adjustment frame 2, ensure good overall locking effect, and high accuracy for repeated use. The first mounting groove 105 and the second mounting groove 205 facilitate the locking of the support frame 1 and the adjustment frame 2 in a suitable position, making adjustment and use convenient. The lifting sling is installed on the hook of the crane, and then the lifting tool is attached to complete the picking up of the C-shaped steel mesh 8 and finally complete the hoisting. After hoisting, the C-shaped steel mesh 8 is secondary fixed at multiple positions using the hand chain hoist 10 and the guy rope 11. The transport vehicle 6 is equipped with lifting lugs that cooperate with the hand chain hoist 10 and the guy rope 11, thereby further ensuring the full fixation of the C-shaped steel mesh 8 on the transport vehicle 6 and ensuring safe and stable transportation.
