Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and more specifically, to a precise positioning and guiding device and method for the construction of a steel structure bridge based on three-dimensional coordinates. Background Art

[0002] A steel structure bridge refers to a bridge with steel as the main load-bearing structure, and its structural forms mainly include steel beam bridges, steel arch bridges, steel cable-stayed bridges, and steel suspension bridges, etc. Due to its advantages such as light self-weight, high strength, fast construction speed, and beautiful appearance, steel structure bridges have been widely used in modern bridge engineering. Especially in large-scale cross-river, cross-sea bridges and urban viaduct projects, steel structure bridges have become the preferred solution by virtue of their unique advantages. Through precise design and construction, a steel structure bridge can achieve high-precision three-dimensional coordinate positioning to ensure the stability and safety of the bridge.

[0003] According to the patent document: A steel structure lifting device for building and road bridge construction disclosed in CN119349387A, which includes a base, a bracket, and a winding mechanism. The bottom of the bracket is fixedly provided with an adjusting component, and the winding mechanisms are symmetrically installed inside the adjusting component. The winding mechanisms control the lateral movement of the two winding mechanisms. The present invention, through the cooperation of a steel wire fixing component, a rotating component, and a lifting seat, when lifting a steel structure, enables the auxiliary steel wire to quickly wind around the outside of the steel structure, and during the rotation process, the two side auxiliary steel wires wrap around the top of the steel structure and self-wind, realizing the tightening of the steel structure. And by pushing the positioning component downward with an electric push rod, the wound auxiliary steel wire is further locked. By locking and fixing the rotating component, quick winding and fixing are completed, maintaining the stability of the lifting, and there is no need to specifically search for a winding rope. The auxiliary steel wire is fixed in the lifting device and can be used at any time, with good use effect.

[0004] In the current technical field, the construction process of a steel structure bridge often involves using a hoisting machine to lift steel structure components to a predetermined installation position. This process requires precise control of the operation of the hoisting machine to ensure that the steel structure components can be accurately positioned at the required installation location. However, in practical applications, when facing a steel structure with a large length, the fixing operation during the hoisting process becomes quite complex and cumbersome. Especially during the hoisting process, the long steel structure components are prone to tilting to one side, which not only increases the risk of the steel structure slipping, but also has an adverse impact on the safety and efficiency of the construction, thus significantly increasing the construction difficulty. Summary of the Invention

The positioning control assembly 32 includes two V-shaped rotating rod hinge blocks 321. The inner sides of the two V-shaped rotating rod hinge blocks 321 are fixedly connected to the tops of the outer sides of the left and right groups of C-shaped connecting rods 314. The outer sides of the two V-shaped rotating rod hinge blocks 321 are rotatably connected to V-shaped rotating rods 322. The bottoms of the two V-shaped rotating rods 322 are fixedly connected to lifting rods 323. The inner sides of the two lifting rods 323 are rotatably connected to H-shaped lifting plates 324. The outer walls of the two H-shaped lifting plates 324 are slidably connected to the inner sides of the two groups of C-shaped connecting rods 314.

The mutually remote sides of the bottoms of the two H-shaped lifting plates 324 are rotatably connected to the tops of the two columnar push rods 317;

[0040] When the steel structure bridge needs to be hoisted and installed in place, at this time, it is connected to the steel structure bridge through the hook 2112. Then, the hoisting vehicle 1 is used to initially lift the hook control frame 2, the steel structure bridge stabilizing mechanism 3 and the connected bridge. After lifting it to a distance of 50 centimeters from the ground, the gas control part 26 is started at this time. The gas control part 26 starts to convey gas into the two pneumatic push rods 25 through two pipelines 27. After receiving the gas, the two pneumatic push rods 25 start to extend, pushing the push plate 28 to move along the chute 22 to both sides. The movement of the push plate 28 drives the expansion and contraction plate 211 to slide on the cross bar 210. At the same time, through the action of the rotating rod 213 and the hinge block 214, the hook connecting rod 2111 slides on the inner wall of the hinge block 214 and the second guide block 2110, thereby adjusting the position of the hook 2112 upward to pull the steel structure bridge upward to the inside of the two inverted concave plates 311. At this time, the outer wall of the steel structure bridge is stuck in the groove at the bottom of the two inverted concave plates 311;

[0041] Meanwhile, with the adjustment of the hook control frame 2, the steel structure bridge stabilizing mechanism 3 also starts to play a role. When the two push plates 28 move outward, they simultaneously push the two groups of Z-shaped push-pull rods 215 to move outward. The movement of the Z-shaped push-pull rods 215 drives the push-pull cross bar 216 to move outward. The outward movement of the two push-pull cross bars 216 further drives the two V-shaped rotating rods 322 to rotate around the axis of the two V-shaped rotating rod hinge blocks 321. As a result, the bottoms of the two V-shaped rotating rods 322 lift the two H-shaped lifting plates 324 upward through the lifting rods 323. During the lifting process, the two H-shaped lifting plates 324 slide along the inner wall of the C-shaped connecting rod 314. At the same time, the upward movement of the two H-shaped lifting plates 324 drives the columnar push-pull rod 317 to slide upward along the outer wall of the columnar push-pull rod guide plate 316. The upward movement of the columnar push-pull rod 317 pulls the rotating short rod hinge block 3110, causing the rotating short rod 3111 to rotate around the hinge point, thereby pushing the L-shaped expansion and contraction plate 318 to slide inward along the chute plate 313. The sliding of the L-shaped expansion and contraction plate 318 causes the C-shaped push-pull plate 319 to move inward to both sides, and then through the two groups of C-shaped push-pull plates 319, the two groups of positioning clamping plates 3113 are pushed to slide inward along the inner wall of the inverted concave plate 311 until the two groups of positioning clamping plates 3113 are closely attached to the outer wall of the steel structure bridge, realizing the stable clamping of the steel structure bridge. At this time, due to the clamping action of the two groups of positioning clamping plates 3113, the position of the steel structure bridge is accurately positioned, avoiding installation errors caused by shaking or deviation during the hoisting process. At the same time, due to the upward pull of the hook 2112, the steel structure bridge is firmly suspended in the air, providing convenience for subsequent installation work;

[0042] After the steel structure bridge is stably clamped, the operator can further adjust the position of the hoisting vehicle 1 to accurately align the steel structure bridge with the installation position, and achieve precise positioning of the three-dimensional coordinates based on the hoisting point and the installation point. At this time, high-precision sensors are used to monitor the positions of the hoisting vehicle 1 and the steel structure bridge in real time to ensure the position accuracy of the steel structure bridge during the installation process. The operator can control the movement of the hoisting vehicle 1 to slowly lower the steel structure bridge along a predetermined trajectory until it is accurately installed in the designed position. During the installation process, the steel structure bridge stabilizing mechanism 3 continuously functions to maintain the stability of the steel structure bridge and prevent it from shaking or shifting during the installation process. Once the steel structure bridge is installed in place, the operator can release the hook control frame 2 to disconnect the hook 2112 from the steel structure bridge. At this time, the steel structure bridge stabilizing mechanism 3 can be automatically unlocked, and the two groups of positioning clamping plates 3113 release the clamping of the steel structure bridge, completing the entire installation process. This precise positioning and guiding device and method for the construction of steel structure bridges based on three-dimensional coordinates greatly improve the installation accuracy and efficiency of steel structure bridges, and reduce the risks and errors during the installation process;

[0043] During the entire construction process, this precise positioning and guiding device and method can ensure the precise installation of the steel structure bridge, greatly improving the construction efficiency and installation quality. At the same time, the device has a simple structure and is easy to operate, is suitable for the construction of steel structure bridges of various scales, and has broad application prospects.

[0044] In addition, the present invention also relates to a precise positioning and guiding device and method for the construction of steel structure bridges based on three-dimensional coordinates, including the following steps:

[0045] Step 1: Transport the hoisting vehicle 1, the hook control frame 2, the steel structure bridge stabilizing mechanism 3, and the steel structure bridge to be installed to the construction site, and ensure that all equipment is in good working condition;

[0046] Step 2: Determine the three-dimensional coordinates of the hoisting point and the installation point according to the specific conditions of the construction site and the design requirements of the steel structure bridge to ensure the position accuracy during the hoisting process;

[0047] Step 3: Connect the steel structure bridge to the hoisting vehicle 1 through the hook control frame 2, and use the adjustment function of the hook control frame 2 to initially lift the steel structure bridge to an appropriate height. At this time, start the gas control member 26, and through the extension of the pneumatic push rod 25, push the expansion and contraction plate 211 and the hook connecting rod 2111 to move, adjust the position of the hook 2112, so that the steel structure bridge can smoothly enter the concave plate 311 of the steel structure bridge stabilizing mechanism 3 and be stably clamped;

[0048] Step Four: After the steel structure bridge is stably clamped, the operator adjusts the position of the hoisting vehicle 1 according to the real-time monitoring data of the high-precision sensor to ensure that the steel structure bridge slowly descends along the predetermined trajectory until it is accurately installed in the designed position;

[0049] Step Five: Once the steel structure bridge is installed in place, the operator releases the hook control frame 2, disconnects the hook 2112 from the steel structure bridge. At the same time, the steel structure bridge stabilizing mechanism 3 is automatically unlocked to release the clamping of the steel structure bridge, completing the entire installation process.

[0050] Working principle of the present invention: When it is necessary to hoist and install and position a steel structure bridge, at this time, it is connected to the steel structure bridge through the hook 2112, and then the hoisting vehicle 1 controls the hook control frame 2, the steel structure bridge stabilizing mechanism 3 and the connected bridge to be initially hoisted. After being hoisted to a distance of 50 cm from the ground, at this time, the gas control member 26 is started. The gas control member 26 starts to convey gas into the two pneumatic push rods 25 through the two pipelines 27. After receiving the gas, the two pneumatic push rods 25 start to extend, pushing the push plate 28 to move along the chute 22 to both sides. The movement of the push plate 28 drives the expansion and contraction plate 211 to slide on the cross bar 210. At the same time, through the action of the rotating rod 213 and the hinge block 214, the hook connecting rod 2111 slides on the inner wall of the hinge block 214 and the second guide block 2110, thereby adjusting the position of the hook 2112 upward to pull the steel structure bridge upward by the hook 2112 to the inside of the two inverted concave plates 311. At this time, the outer wall of the steel structure bridge is stuck in the groove at the bottom of the two inverted concave plates 311. At the same time, with the adjustment of the hook control frame 2, the steel structure bridge stabilizing mechanism 3 also starts to function. When the two push plates 28 move outward, they simultaneously push the two groups of Z-shaped push-pull rods 215 to move outward. The movement of the Z-shaped push-pull rods 215 drives the push-pull cross bar 216 to move outward. The outward movement of the two push-pull cross bars 216 drives the two V-shaped rotating rods 322 to rotate around the two V-shaped rotating rod hinge blocks 321 as the axis, so that the bottom of the two V-shaped rotating rods 322 lifts the two H-shaped lifting plates 324 upward through the lifting rod 323. During the lifting process, the two H-shaped lifting plates 324 slide along the inner wall of the C-shaped connecting rod 314. At the same time, the upward movement of the two H-shaped lifting plates 324 drives the columnar push-pull rod 317 to slide upward along the outer wall of the columnar push-pull rod guide plate 316. The upward movement of the columnar push-pull rod 317 pulls the rotating short rod hinge block 3110, causing the rotating short rod 3111 to rotate around the hinge point, thereby pushing the L-shaped expansion and contraction plate 318 to slide inward along the chute plate 313. The sliding of the L-shaped expansion and contraction plate 318 causes the C-shaped push-pull plate 319 to move inward to both sides, and then through the two groups of C-shaped push-pull plates 319, the two groups of positioning clamping plates 3113 are pushed to slide inward along the inner wall of the inverted concave plate 311 until the two groups of positioning clamping plates 3113 are closely attached to the outer wall of the steel structure bridge. After the steel structure bridge is stably clamped, the operator can further adjust the position of the hoisting vehicle 1 to accurately align the steel structure bridge with the installation position, and achieve precise positioning of the three-dimensional coordinates based on the hoisting point and the installation point. At this time, high-precision sensors are used to monitor the positions of the hoisting vehicle 1 and the steel structure bridge in real time to ensure the position accuracy of the steel structure bridge during the installation process. The operator can control the movement of the hoisting vehicle 1 to make the steel structure bridge slowly descend along the predetermined trajectory until it is accurately installed in the designed position. During the installation process, the steel structure bridge stabilizing mechanism 3 continues to function to maintain the stability of the steel structure bridge.Prevent it from shaking or shifting during the installation process. Once the steel structure bridge is installed in place, the operator can loosen the hook control frame 2 to disconnect the hook 2112 from the steel structure bridge. At this time, the steel structure bridge stability mechanism 3 can be automatically unlocked, and the two groups of positioning clamping plates 3113 loosen the clamping of the steel structure bridge, completing the entire installation process.
