[0002] With social development, road and bridge engineering projects, as fundamental infrastructure projects, are an important component of urban transportation networks. Highway bridges and viaducts often utilize bridge piers for support; therefore, the construction of bridge piers is one of the key aspects of road and bridge engineering projects. In current bridge pier cap beam construction, to improve construction efficiency and reduce high-altitude work time, an integrated construction process for cap beam supports has emerged. This process involves the overall lifting, lowering, dismantling, and adjustment of the cap beam support assembled on the ground. Feasible implementation can be achieved using a lifting device installed on the pier top. This lifting device uses steel strands and lifting equipment to hoist the cap beam support. However, the current practical application problem is that the rear steel strands are directly suspended from the pier top without a systematic structure for protection and storage, leading to easy wear and breakage of the steel strands and posing safety risks. Therefore, it is necessary to design a steel strand winding and unwinding support structure for the pier top hoisting device. Summary of the Invention

[0006] As a further explanation of this utility model, the arc-shaped wire groove includes a first side plate and a second side plate, and a plurality of first crossbars and second crossbars are provided at intervals between the first side plate and the second side plate. The first crossbars are provided on the lower side of the arc-shaped wire groove, and the second side plate is provided on the upper side of the arc-shaped wire groove.

[0019] Example:

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] As attached Figure 1-3 As shown in this embodiment, a non-powered wire winding and unwinding support for a pier-top hoisting device includes a wire arc-shaped support assembly and a winding and unwinding wheel assembly, which are fixedly mounted on a sliding platform 9. The wire arc-shaped support assembly includes an arc-shaped wire groove 1 and a groove support 2. The arc-shaped wire groove 1 has a first wire guide opening 101 at one end and a second wire guide opening 102 at the other end, and is mounted via the groove support 2. The winding and unwinding wheel assembly is connected at the second wire guide opening 102 and includes a receiving wheel frame 3 and a wheel support 4. The receiving wheel frame 3 is rotatably mounted on the wheel support 4. This non-powered wire winding and unwinding support for a pier-top hoisting device is used in the overall lifting and lowering construction process of a cap beam support. It is set up in conjunction with a sliding platform to achieve non-powered winding and unwinding of the steel strands for the pier-top hoisting device. In practical applications, the pier-top hoisting device uses continuous jacks 7 and steel strands to lift and lower the cap beam support as a whole. As shown in the attached diagram, the upper end of the continuous jack 7 is the take-up and undo end of the steel strand 8. During the overall lifting operation of the cap beam support, the steel strand needs to be taken up. Specifically, under the action of the continuous jack 7, the steel strand will move along the arc-shaped guide groove 1, changing from the upward movement direction at the first steel strand guide opening 101 to the downward movement direction at the second steel strand guide opening 102, thus facilitating the final take-up of the steel strand on the receiving wheel 3. Conversely, the process is reversed during the overall lowering operation of the cap beam support, which will not be described in detail here. During the overall lifting or lowering operation of the cap beam support, the take-up and undo power of the steel strand mainly relies on the power of the continuous jack 7 itself. As can be seen, the structure of the steel strand unpowered winding and unwinding bracket of the pier top hoisting device in this embodiment is simple in structure, lightweight, and can be quickly installed and fixed. It is mainly suitable for the overall lifting and lowering construction process of the cap beam bracket. It is used in conjunction with the pier top hoisting device to realize the unpowered winding and unwinding of steel strands, solve the problems of steel strand protection and storage, reduce wear and breakage of steel strands, improve safety and service life, and reduce process costs. The overall structure is a unpowered mechanical structure, relying on the power of the pier top hoisting device itself to realize the winding and unwinding of steel strands, avoiding common faults in circuit and power systems, and is lightweight and efficient.

[0023] See appendix Figure 2 As shown, specifically, the arc-shaped conductor groove 1 in this embodiment includes a first side plate 103 and a second side plate 104. A plurality of first crossbars 105 and second crossbars 106 are spaced apart between the first side plate 103 and the second side plate 104. The first crossbars 105 are located on the lower side of the arc-shaped conductor groove 1, and the second side plate 104 is located on the upper side of the arc-shaped conductor groove 1. Thus, on the one hand, the non-powered winding and unwinding support for the steel strand of the pier-top hoisting device in this embodiment is installed and disassembled along with the pier-top hoisting device in practical applications. Under this structural design, the overall weight of the non-powered winding and unwinding support for the steel strand of the pier-top hoisting device can be minimized, reducing the strength requirements of the related structural supports. On the other hand, it can reduce the friction between the steel strand and the arc-shaped conductor groove 1 during the winding and unwinding process, making the winding and unwinding movement smoother, reducing wear on the steel strand, improving safety and service life, and under the constraint of the first crossbars 105 and the second crossbars 106, it also basically meets the requirements for guiding and restricting the movement of the steel strand. In a preferred embodiment, as shown in the accompanying drawings, the first crossbar 105 and the second crossbar 106 are staggered, which can relatively well realize the above-mentioned functions of the arc-shaped wire groove 1.

[0024] See appendix Figure 1 As shown, specifically, the outer side of the receiving wheel frame 3 is provided with several arc-shaped rods 5 at intervals to restrict the winding shape of the steel strand. Similar to the structure of the arc-shaped conductor groove 1 described above, the structural design of the receiving wheel frame 3 in this embodiment, while satisfying the function of storing the steel strand, also has the effect of reducing the weight of the winding and unwinding wheel assembly and reducing wear on the steel strand. In a preferred embodiment, as shown in the attached figure, at least one steel strand guard 6 is provided between the arc-shaped rods 5 to better restrict the winding shape of the steel strand.

[0025] Feasible, as shown in the attached figure, the wire trough support 2 in this embodiment includes a vertical rod support 201 and a horizontal beam support 202 forming a cross-shaped support. The vertical rod support 201 is connected to the side of the arc-shaped conductor trough 1 near the first steel strand conductor opening 101. This results in a more compact structural layout, reduces structural strength requirements, and provides sufficient space for the take-up and release wheel assembly. To ensure structural strength, a corbel diagonal brace 203 is also provided between the first steel strand conductor opening 101 of the arc-shaped conductor trough 1 and the wire trough support 2. Specifically, the main supports of the wire trough support 2 and the wheel support 4 can be made of I-beam profiles. As mentioned above, to achieve the installation and fixation of the non-powered take-up and release support for the steel strand in the pier-top hoisting device, an installation and fixing structure can be set at the bottom of the wire trough support 2 and the wheel support 4 to respectively achieve the installation and fixation of the arc-shaped conductor support assembly and the take-up and release wheel assembly, so as to realize the take-up and release of the steel strand during the overall lifting and lowering operation of the cap beam support.

[0026] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. In short, all changes made within the scope of the independent claims of the present invention are within the scope of protection of the present invention.
