Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a method for quickly and efficiently fixing and loading C-shaped steel mesh onto a vehicle. 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.

[0003] The formed steel mesh is generally C-shaped, characterized by its heavy weight, large size, and high flexibility. It must be securely fixed during loading; otherwise, the C-shaped steel mesh is easily damaged during transportation, potentially leading to safety accidents. Conventional methods typically use pallets to support the steel mesh. The process involves first hoisting the steel mesh onto the pallet and securing it, then placing the pallet onto a flatbed truck and securing it. This method generally requires high lifting capacity from the on-site cranes (a single piece of equipment typically has a lifting capacity of at least three times the weight of the steel mesh) and involves secondary transfers. Therefore, it has certain drawbacks in terms of economy and convenience. Thus, there is an urgent need for a C-shaped steel mesh securing device and a rapid loading method to achieve fast, safe, and efficient transportation of the steel mesh.

[0004] Chinese patent document CN 104692227 A describes a rebar mesh lifting device and a rebar mesh lifting method, but this device does not have a good fixing ability for C-shaped rebar mesh; Chinese patent document CN 215322234 U describes a combined rebar transport frame, but this structure also cannot handle the clamping and fixing of rebar mesh with C-shaped structure, and cannot guarantee efficient and stable loading. It has defects in use and needs to be improved. Summary of the Invention

[0005] This invention provides a method for quickly and efficiently fixing and loading C-shaped steel mesh onto vehicles, solving the problems of low loading efficiency, poor fixing accuracy and quality, and transportation risks caused by relatively complex installation and insufficient fixing.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for quickly and efficiently fixing and loading C-shaped steel mesh onto a vehicle, comprising the following steps: S1.

Adjust the position of the adjustment frame until the width of the clamping area meets the locking requirements of the C-shaped steel mesh, and then fix the adjustment frame. S5. Connect and fix the C-shaped steel mesh to the transport vehicle on both sides using hand-operated hoists and guy ropes; S6. Disconnect the C-shaped steel mesh from the lifting device and move the lifting device to a safe position; S7. Repeat S2 to S6 to complete the installation of C-shaped steel mesh on all transport vehicles.

[0009] In the preferred embodiment, S3 includes the following steps: S31.

S32. The calibration assembly is installed into the first fixing hole on the support frame through the connector. The slide rod in the calibration assembly is moved out of the sleeve and then locked with bolts to ensure that the distance between the two baffles matches the spacing on both sides of the C-shaped steel mesh. The distance between the vertical plates on both sides is adjusted by the bidirectional threaded sleeve to ensure that the distance between the first arc grooves on the two vertical plates is equal to the spacing between the two vertical bars.

[0014] In a preferred embodiment, the structure of the first fixing component is as follows: the first fixing component includes a vertical plate, the vertical plate is connected to a first threaded rod and a bidirectional threaded sleeve, the bidirectional threaded sleeve is rotatably mounted on the L-shaped plate, and the bidirectional threaded sleeve is used to change the position of the vertical plate; A seventh fixing hole runs through the center of the L-shaped plate. Multiple third threaded holes are provided circumferentially on the outer side of the seventh fixing hole. Multiple second threaded holes are provided on both sides of the seventh fixing hole. A second gap is provided between the two L-shaped plates. The first fixing component includes a bidirectional threaded sleeve, a locking disc, and a round rod. The bidirectional threaded sleeve is located in the second gap and passes through the seventh fixing hole. The locking disc is connected to the third threaded hole through a locking pin.

A second through hole runs through the second ear plate. The guide rod passes through the second ear plate. A nut for limiting the vertical plate is also threadedly connected to the guide rod.

[0015] In the preferred embodiment, the safety component has the following structure: the safety component is connected to the support frame via a second telescopic cylinder. The safety component includes two opposing baffles, with a fourth ear plate connected to both sides of the baffles via a transition plate. Two hinge plates are parallel to each other on the outer side of the triangular plate. Locking pins pass through the hinge plates and the fourth ear plates.

The transition plate is inclined outward toward the support frame.

[0016] The beneficial effects of this invention are as follows: By setting up a support frame and an adjustment frame, a stable clamping foundation is formed. The cantilever plate on the transport vehicle facilitates the positioning and locking of the support frame and adjustment frame. Simultaneously, a second fixing component and a first fixing component are respectively set on the support frame and adjustment frame, which can fully lock the transverse and vertical bars according to the structural characteristics of the C-shaped steel mesh, thereby ensuring sufficient overall fixation of the C-shaped steel mesh and completely restricting its degrees of freedom. Furthermore, the second and first fixing components 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 set on the support frame, which can further enhance the stability of the C-shaped steel mesh. The fixed effect provides a system-wide 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 and correcting deviations during the hoisting and lowering of the C-shaped steel mesh into the transport vehicle. During the hoisting process, multiple components cooperate with each other to improve the overall hoisting efficiency and ensure the quality of hoisting. Attached Figure Description

Detailed Implementation

[0019] like Figure 1-10 A method for quickly and efficiently fixing and loading C-shaped steel mesh onto a vehicle includes the following steps: S1. Complete the fabrication of support frame 1 and adjustment frame 2 according to the design parameters; S2. The support frame 1 and the adjustment frame 2 are pre-assembled with bolts 3 and nuts 4 to form the clamping area 5, and then the whole assembly is installed on the transport vehicle 6. S3. After fixing the support frame 1, use the lifting tool 7 and sling 9 to take the C-shaped steel mesh 8 out of the stacking point and then lift it into the clamping area 5; S4. Adjust the position of the adjustment frame 2 until the width of the clamping area 5 meets the locking requirements of the C-shaped steel mesh 8, and then fix the adjustment frame 2. S5. The C-shaped steel mesh 8 is connected and fixed to the transport vehicle 6 by hand-operated hoists 10 and guy ropes 11 on both sides. S6. Disconnect the connection between the C-shaped steel mesh 8 and the lifting device 7, and move the lifting device 7 to a safe position; S7. Repeat S2 to S6 to complete the installation of C-shaped steel mesh 8 on all transport vehicles 6.

[0020] The support frame 1 has a triangular cross-section, and the adjustment frame 2 has an L-shaped cross-section. Both are made of steel plates, ensuring structural stability, high strength, and sufficient overall stress distribution. Operation is convenient, and the lifting effect is excellent. The manual hoist 10 allows for flexible adjustment of the pulling force, while the guy ropes 11 form a V-shape on both sides for enhanced stability. The transport vehicle 6 is equipped with lifting lugs for easy securing of the manual hoist 10 and guy ropes 11, ensuring sufficient stress distribution.

[0021] In use, the steel bars are first processed mechanically 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. At the same time, multiple support frames 1 and adjustment frames 2 are made. The appropriate number of support frames 1 and adjustment frames 2 are installed according to the length of the C-shaped steel bar mesh 8. The transport vehicle 6 is equipped with cantilever plates 601 and locking holes 602 to cooperate with the support frames 1 and adjustment frames 2. Before transportation, the position of the support frames 1 is adjusted according to the specifications of the C-shaped steel bar mesh 8 to be transported. In use, the support frames 1 are first installed on the transport vehicle 6. In order to ensure that the axes of the support frames 1 and adjustment frames 2 are aligned, bolts 3 and nuts 4 are used to pre-assemble the support frames 1 and adjustment frames 2. The whole assembly is then installed on the transport vehicle 6, and the support frames 1 are then fully fixed.

[0022] In the preferred embodiment, S1 includes the following steps: S11. The support frame 1 is formed by connecting the triangular plate 101, the first connecting plate 102 and the second connecting plate 103, and the adjustment frame 2 is formed by connecting the L-shaped plate 201 and the third connecting plate 210. S12. First mounting groove 105 and second mounting groove 205 are machined on the outer sides of support frame 1 and adjustment frame 2 respectively; S13. A notch 113 is machined in the lower part of the support frame 1, and a reference plate 206 is installed in the lower part of the adjustment frame 2. S14. Machining the second fixing hole 108 and the sixth fixing hole 204 on the first pair of positioning seats 104 and the second pair of positioning seats 203 respectively, and then installing them on both sides of the triangular plate 101 and the L-shaped plate 201. S15. Install calibration component 13, second fixing component 15, safety component 16, second telescopic cylinder 18 and third telescopic cylinder 19 on support frame 1. Install first fixing component 14 on adjustment frame 2. Support frame 1 and adjustment frame 2 are connected by first telescopic cylinder 12. Adjust the position of first cylinder body 1201 and first push rod 1202 on first telescopic cylinder 12. Then install first cylinder body 1201 on first alignment seat 104 through first mounting seat 1203. Install first push rod 1202 on second alignment seat 203 through synchronization plate 1204.

[0023] Because the support frame 1 is larger and heavier than the adjustment frame 2, it occupies more space on the transport vehicle 6 and is less convenient to move than the adjustment frame 2. In order to ensure the convenience and efficiency of the overall operation, a combination of fixed support frame 1 and movable adjustment frame 2 is adopted to improve the clamping response speed.

[0024] During operation, the bottom support head 1503 on the second fixing component 15 supports the transverse reinforcement 801, and the vertical plate 1407 on the first fixing component 4 abuts against the vertical reinforcement 802. At the same time, the bottom support head 1503 and the vertical plate 1407 are respectively provided with a second slot 1504 and a first slot 1412. Since the same type of C-shaped steel mesh 8 is formed by the cooperation of multiple transverse reinforcements 801 and multiple vertical reinforcements 802, the size of its mesh is uniform. The vertical plate 1407 on the first fixing component 14 first completes the fit of the vertical reinforcement 802, and then moves the adjustment frame 2 facing the support frame 1 to change the angle of the bottom support head 1503 on the second fixing component 15, supporting the transverse reinforcement 801 from 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. 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.

[0025] In the preferred embodiment, S2 includes the following steps: S21. After inserting the bolt 3 into the second fixing hole 108, multiple nuts 4 are fitted in. Then the bolt 3 is passed out from the second threaded hole 208 and locked on the outside of the bolt 3. By using bolts 3 and nuts 4, the support frame 1 and the adjusting frame 2 are first locked in their initial positions using multiple nuts 4, completing the pre-assembly of the support frame 1 and the adjusting frame 2. Then, they are installed on the transport vehicle 6. At this time, it can be ensured that the movement direction of the support frame 1 and the adjusting frame 2 is coaxial, which is beneficial to ensure the subsequent clamping effect and accuracy. Then, the locking of the nuts 4 on the adjusting frame 2 near the support frame 1 is released to facilitate subsequent operations. The first pair of positioning seats 104 and the second pair of positioning seats 203 respectively increase the contact area between the support frame 1 and the adjusting frame 2 and the bearing surface of the transport vehicle 6, resulting in more sufficient overall force and better bearing capacity. At the same time, they cooperate with each other to play a guiding and limiting role. After the adjustment is in place, the first telescopic cylinder 12 is installed, so that the fixing device can simultaneously have both automatic and manual states, with each serving as a backup, improving the 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 usage costs.

[0026] S22. Install multiple cantilever plates 601 on both sides of the transport vehicle 6, and provide at least two locking holes 602 on the cantilever plates 601. S23. Adjust the positions of support frame 1 and adjustment frame 2, and insert bolt 3 into the first mounting groove 105, the second mounting groove 205 and the lock hole 602 to complete the locking.

[0027] In the preferred embodiment, S3 includes the following steps: S31. Adjust the calibration component 13, the first fixing component 14 and the second fixing component 15 according to the specifications and dimensions of the C-shaped steel mesh 8, while keeping the safety component 16 in the closed state. S32. The calibration component 13 is installed into the first fixing hole 106 on the support frame 1 via the connector 1304. The slide rod 1302 in the calibration component 13 is removed from the sleeve 1301 and then locked with bolts 3 to ensure that the distance between the two baffles 1303 matches the spacing on both sides of the C-shaped steel mesh 8. The distance between the vertical plates 1407 on both sides is adjusted by the bidirectional threaded sleeve 1401 to ensure that the distance between the first arc grooves 1412 on the two vertical plates 1407 is equal to the spacing between the two vertical ribs 802. The number of bottom support heads 1503 that need to work is adjusted as needed, and bottom support heads 1503 that may interfere are removed. 503 ensures that the distance between the second arc groove 1504 on the two bottom support heads 1503 and the spacing between the two transverse ribs 801 are equal; thus satisfying the supporting function of the transverse ribs 801. The third telescopic cylinder 19 can 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, thus completing the support of the C-shaped steel mesh 8. It is convenient to use and has high operating efficiency.

[0028] 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.

[0029] S33. During the lowering process of the C-shaped steel mesh 8, the C-shaped steel mesh 8 is aligned with the clamping area 5 and lowered. When the bottom of the C-shaped steel mesh 8 is close to the top of the baffle 1303, the position of the C-shaped steel mesh 8 is slightly adjusted to ensure that the C-shaped steel mesh 8 is on the outside of the two baffles 1303. When the bottom of the C-shaped steel mesh 8 is lower than the top of the baffle 1303, it is lowered continuously until it reaches the lowest point and contacts the reference plate 206.

After the C-shaped steel mesh 8 and the support frame 1 reach the design position, firstly, use the second telescopic cylinder 18 to open the safety component 16, release the locking state of the top plate 1501 through the insertion rod 1506, and then use the third telescopic cylinder 19 to open the second fixing component 15, and lift the C-shaped steel mesh 8 through the bottom support head 1503. S43. Use the second telescopic cylinder 18 to close the safety component 16 until the baffle 1601 abuts against the transverse reinforcement 801 to complete the locking of the C-shaped steel mesh 8. S44. After the entire structure is subjected to force, the top plate 1501 is locked again by inserting rod 1506.

[0031] like Figure 11-20 In the preferred embodiment, the structure of the third telescopic cylinder 19 is as follows: 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; during installation, the top plate 1501 and the follower head 1502 are first installed on the triangular plate 101, and then the third push rod 1902 and the top plate 1501 are connected.

[0033] The rotation of the top plate 1501 with multiple follower heads 1502 is smooth and efficient. 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 the convenience of operation, a sound-emitting air bladder can be used. When the top plate 1501 or the follower head 1502 squeezes the rubber bladder, it will make a sound to remind the operator to operate in place. The reinforcing block 1507 can improve the support effect on the bottom support head 1503, thereby ensuring sufficient restraint on the transverse rib 801. When the top plate 1501 is in the highest position, the follower head 1503 is in the 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 fine-tune the mesh size of different 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 provide sufficient support for the transverse reinforcement 802.

[0034] In a preferred embodiment, the base support head 1503 has the following structure: a second threaded rod 1515 is provided at the end of the base support head 1503; a first threaded hole 1514 is provided at the end of the follower head 1502; the second threaded rod 1515 and the first threaded hole 1514 are threadedly connected; grooves 1508 are symmetrically provided on the lower side of the top plate 1501; a fourth through hole 1509 is provided through the grooves 1508; and a third ear plate 1517 is provided at the end of the drive seat 1516. 17.

The appropriate position of the bottom support head 1503 is selected according to the specifications and dimensions of the C-shaped steel mesh 8, and any bottom support heads 1503 that may cause interference are removed. The position of the drive seat 1516 relative to the top plate 1501 can be changed as needed, thereby changing the drive response speed to ensure better response and more efficient operation. The length of the bottom support head 1503 can also be changed as needed to meet the requirements of different mesh lengths, resulting in better support.

[0035] like Figure 21-24 In the preferred embodiment, the structure of the first fixing component 14 is as follows: the first fixing component 14 includes a vertical plate 1407, the vertical plate 1407 is connected to 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 the bidirectional threaded sleeve 1401 is used to change the position of the vertical plate 1407.

The outer diameter of the double-threaded sleeve 1401 is provided with a hexagonal head 1406 in the middle, a round rod 1403 and a second threaded hole 208 are threadedly connected, and guide rods 1404 are symmetrically provided on the outer side of the round rod 1403. The vertical plate 1407 is provided with a first ear plate 1408 in the middle, and a first threaded rod 1409 is provided on the first ear plate 1408. The two opposite first threaded rods 1409 are respectively threadedly connected to the double-threaded sleeve 1401. Multiple second ear plates 1410 are provided on both sides of the first ear plate 1408. A second through hole 1411 is passed through the second ear plate 1410. The guide rod 1404 passes through the second ear plate 1410. A nut 4 for limiting the vertical plate 1407 is also threadedly connected to the guide rod 1404.

[0036] In use, first, install the bidirectional threaded sleeve 1401. Then, use the locking disc 1402 to limit the bidirectional threaded sleeve 1401, ensuring that it can only rotate within the seventh fixing hole 207. Use a wrench to hold the hexagonal head 1406 and rotate it to change the angle of the bidirectional threaded sleeve 1401. Then, install the round rod 1403. Preferably, the thread length in the middle of the round rod 1403 is equal to the thickness of the adjusting bracket 2, so as to facilitate the accurate installation position of the round rod 1403. Then, insert the vertical plate 1407 into the guide rods 1404 on both sides of the round rod 1403, gradually approaching the bidirectional threaded sleeve 1401. Then, rotate the bidirectional threaded sleeve 1401 to retract the first threaded rod 1409, ensuring that the position between the vertical plates 1407 on both sides meets the spacing requirements between two adjacent vertical bars 802. At the same time, it can be adjusted within a certain distance range to meet the clamping use of different specifications of C-shaped steel mesh 8. The structure is compact and easy to use.

[0037] like Figure 25-35In the preferred embodiment, the safety component 16 has the following structure: the safety component 16 is connected to the support frame 1 via the 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 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. When the C-shaped steel mesh 8 is lowered, the second telescopic cylinder 18 is operated to close the safety component 16. 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 reference plate 206, the second telescopic cylinder 18 is operated to open the safety component 16, exposing the follower head 1503. The position of the adjustment valve 2 is changed to push the C-shaped steel mesh 8 closer to the support frame 1. The follower head 1503 rotates to fix 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 are reduced. At this time, the C-shaped steel mesh 8 is completely locked.
