[0023] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example 1 like Figures 1-3 As shown, a steel strand cable-stayed hanging basket traveling synchronous jacking device according to this embodiment includes a drive mechanism 1, a steel strand 2, and a clamping mechanism. The main structure of the drive mechanism 1 is fixed on the hanging basket 5. The power output end of the drive mechanism 1 is fixedly connected to one end of the steel strand 2 and can drive the steel strand 2 to move axially. The other end of the steel strand 2 is fixed with a clamping mechanism for clamping onto the end of the traveling track 7 on the bridge 6.

[0025] Preferably, the driving mechanism 1 in this embodiment is a hydraulic jack. The power output end of the driving mechanism 1 is the tool anchor of the hydraulic jack, used to clamp and fix the steel strand. By using a hydraulic jack as the driving mechanism, installation is convenient and a stable driving force can be provided.

[0026] In this embodiment, the hydraulic jacks are connected to an intelligent hydraulic pump station via oil pipes. The intelligent hydraulic pump station controls the movement of the hydraulic jacks, enabling them to push and stop, ensuring stable forward movement of the basket and preventing twisting. The hydraulic jacks can be 25t tension, 300mm range through-hole jacks. The steel strand is φ15.2 low-relaxation high-strength steel strand. Through the hydraulic jacks, clamping mechanism, and steel strand, the oil pump of the intelligent hydraulic pump station drives the steel strand for effective traction, achieving rapid basket movement, simple disassembly, and safe and reliable operation.

[0027] The steel strand cable-stayed hanging basket traveling synchronous jacking device of this embodiment can realize the forward and backward movement of the hanging basket on the bridge, thereby ensuring high efficiency of hanging basket movement, good synchronous control accuracy, simple installation and dismantling methods, low investment cost, and ensuring the safety of construction workers.

[0028] Example 2 Based on Embodiment 1, this embodiment provides a preferred solution for the snap-fit ​​mechanism. For example... Figures 1-3 As shown, the snap-fit ​​mechanism in this embodiment includes a snap-fit ​​plate 3, and the other end of the steel strand 2 passes vertically through the snap-fit ​​plate 3 and is fixedly connected to the snap-fit ​​plate 3. By setting the snap-fit ​​plate, it is convenient to snap-fit ​​and position it with the end of the traveling track.

[0029] like Figure 2 and Figure 3 As shown, in one specific embodiment, the other end of the steel strand 2 is locked and fixed to the snap-fit ​​plate 3 by a locking nut 4.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the snap-fit ​​plate 3 in this embodiment has a flat plate structure or an L-shaped plate structure. The snap-fit ​​plate 3 is made of a standard 15cm×15cm×4cm steel plate.

[0031] Optionally, a rubber pad is fixed on the side of the snap-fit ​​plate 3 near the drive mechanism 1.

[0032] Example 3 This embodiment provides a hanging basket assembly, including a steel strand cable-stayed hanging basket traveling synchronous jacking device as described in Embodiment 1 or Embodiment 2 above, and also includes a hanging basket 5 and a traveling track 7. The traveling track 7 is fixed to the upper surface of the bridge 6 along the construction direction of the bridge 6. The rear end of the hanging basket 5 is installed on the traveling track 7 through a traveling mechanism 10 and can move along the traveling track 7. The main structure of the driving mechanism 1 is fixed in the middle of the hanging basket 5. The locking mechanism is locked to the front end of the traveling track 7 along the construction direction. The power output end of the driving mechanism 1 is fixedly connected to one end of the steel strand 2 and drives the hanging basket 5 to move forward along the construction direction by driving the steel strand 2.

[0033] like Figures 1-3 As shown, steel sleepers 8 can be laid on the bridge 6 in this embodiment. The steel sleepers 8 can be extended along the width direction (i.e., the left and right direction) of the bridge. Then, a walking track 7 is laid on the steel sleepers 8. The walking track 7 is laid along the length direction of the bridge 6. The hanging basket 5 is movably set on the walking track 7 using a walking mechanism 10. The walking mechanism 10 can be any walking equipment commonly used in construction or hanging baskets, such as power-driven rollers.

[0034] like Figures 1-3As shown, in this embodiment, the main structure of the drive mechanism 1 is fixed to the central upright 11 of the hanging basket 5. The drive mechanism 1 is located behind the central upright 11, and the power output end of the drive mechanism 1 is arranged facing rearward. The central upright 11 is located in the middle of the overall structure of the hanging basket 5 and is a vertically arranged rod-shaped structure.

[0035] like Figures 1-3 As shown, this embodiment of the steel strand cable-stayed hanging basket synchronous jacking device has two configurations. There are two hanging baskets 5 and two traveling tracks 7. One hanging basket 5 is attached to each of the front and rear ends of the bridge 6. One traveling track 7 is fixed to the upper surface of the bridge 6 near each of the front and rear ends. Each hanging basket 5 is connected to its corresponding traveling track 7 via the steel strand cable-stayed hanging basket synchronous jacking device. (Reference) Figure 1 The directions indicated in the diagram can be used to drive two hanging baskets 5 to move forward along the length of the bridge 6 using two drive mechanisms. By setting up two hanging baskets and two traveling tracks, simultaneous basket movement operations in two opposite construction directions can be achieved, improving construction efficiency.

[0036] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the rear end of the hanging basket 5 is detachably connected to the wing plate of the bridge 6 via a rear anchor beam 9. The rear anchor beam facilitates detachable positioning and fixing between the hanging basket and the bridge. When the basket is in place, it can be connected to the bridge via the rear anchor beam. When construction is complete and the basket needs to be moved, the rear anchor beam can be removed for the basket relocation operation.

[0037] In this embodiment, the hydraulic jacks are connected to the intelligent hydraulic pump station via oil pipes. The intelligent hydraulic pump station controls the movement of the two hydraulic jacks to achieve synchronous pushing and synchronous stopping of the hydraulic jacks, ensuring absolute synchronization of the basket's forward movement and preventing twisting.

[0038] In this embodiment, when installing the aforementioned steel strand cable-stayed hanging basket synchronous jacking device, one end of the steel strand is anchored to the clamping plate at the end of the traveling track, and the other end passes through a hydraulic jack fixed to the hanging basket. The hydraulic pump station is activated, the hydraulic jack clamps the steel strand, and extends backward. Because the hydraulic jack is fixed to the central upright of the hanging basket, its reaction force propels the entire hanging basket system forward. After one stroke, the hydraulic jack retracts and automatically releases the tool anchor, clamping the steel strand at the next point. This "jacking-returning" cycle is repeated until the hanging basket is pushed to the designated design position. The entire process resembles a "worm" crawling or "pulling a rope" to move forward. This effectively improves work efficiency, saves labor and material costs and construction time, and ensures the safety of operators.

[0039] The hanging basket assembly in this embodiment has the following advantages: 1. Long-stroke continuous jacking: Utilizing the infinite extensibility of the steel strand, a single jacking stroke is equivalent to the full stroke of the jack (typically 300mm), making it far more efficient than ordinary jacking methods, eliminating the need for mid-stroke reversal. 2. High precision in synchronous control: The hydraulic system can monitor the pressure and displacement of the hydraulic jacks on both sides in real time, automatically adjusting to ensure the hanging basket moves smoothly and linearly, avoiding safety risks and structural damage caused by asynchrony. 3. Safe and reliable: The steel strand has extremely high tensile strength, and the hydraulic system has overload protection. Even if the system loses pressure, the hydraulic jacks and anchors can still clamp the steel strand, forming a self-locking mechanism to prevent the hanging basket from slipping. 4. Strong adaptability: It has relatively low requirements for track flatness and is suitable for cantilever construction of various bridge types and spans.

[0040] The hanging basket assembly in this embodiment ensures high efficiency in moving the hanging basket, good synchronous control accuracy, simple installation and dismantling methods, low investment cost, and guarantees the safety of construction workers.
