These decorative blocks are often of irregular structure, heavy weight, and located at high altitudes.
[0003] At present, during the construction of bridge towers, tower cranes with lifting capacity are usually configured for high-altitude lifting of objects. Since decorative blocks often have irregular structures and heavy weights, the installation of such large-tonnage irregular decorative blocks is very difficult. Usually, the decorative blocks need to be cut into many fragmented components so that the weight of each component is less than the lifting capacity of the tower crane, and then the tower crane is used to lift and install many components.
[0004] The more segments the decorative blocks are divided into, the more splicing work will be done, which will invisibly increase the error in the installation of the decorative blocks. In addition, the number of times the tower crane is used for lifting will also increase accordingly, which also increases the risk of lifting. Summary of the invention

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0035] The embodiment of the present application provides a lifting system for a decorative block, which can solve the defect of increasing installation errors and installation risks by cutting and lifting the decorative blocks.
[0036] See also Figures 1 to 12 As shown, an embodiment of the present application provides a lifting system for a decorative block, including: a frame system and a lifting device, wherein the frame system is generally used to be installed on the top of the main tower 90 to provide a good supporting platform for the lifting device.
[0037] In the present application, a lifting device is provided, and the lifting device includes two lifting units, and the lifting unit includes two lifting components, and the lifting component includes a winch 1 and a pulley block, and the winch 1 is installed on the frame system; the pulley block includes a steel wire rope (not shown in the figure), a fixed pulley block 20 and a movable pulley block 21, one end of the provided steel wire rope is connected to the winch 1, and the other end is wound around the fixed pulley block 20 and the movable pulley block 21, and a hanging point for connecting the decorative block 91 is provided on the movable pulley block 21; and, in the lifting component of one of the lifting units, the steel wire rope is fixed on the movable pulley block 21, and in the two lifting components of the other lifting unit, the two steel wire ropes are connected after being wound around a reversing fixed pulley 22 respectively.
[0038] Therefore, in the present application, a set of reliable lifting devices is formed by a total of four winches 1, wire ropes and pulley blocks in two lifting units, and in a lifting assembly of one lifting unit, the wire rope is fixed on the movable pulley block 21, and in the two lifting assemblies of the other lifting unit, two wire ropes are connected after winding through a reversing fixed pulley 22, so that there are four lifting points between the four winches 1. Based on the fact that the two winches 1 share a wire rope, the present application adopts a special rope winding method to make the decorative block 91 in a state of four-point lifting and three-point balance during lifting, so as to ensure that the force of the wire rope is uniform. Therefore, for the lifting construction of the special-shaped decorative block 91, the cutting of the large component special-shaped decorative block 91 can be minimized. For example, for an N-shaped decorative block 91, it can be cut into only three block units at most. During the lifting process, the posture of the decorative block 91 in the air can be adjusted by using the four-point lifting and three-point balance, and the lifting is reliable and safe. Moreover, after the number of cuts of the decorative block 91 is reduced, the number of lifting and assembling times is also reduced, thereby effectively reducing installation errors and improving installation efficiency.
[0039] In other embodiments, when the number of cuts of the decorative block 91 is too large, not only the number of hoisting times will increase accordingly, but also the long-term installation operation at high altitude will increase the risk of hoisting and will also cause more joints between the segments of the decorative block 91, thereby reducing the installation efficiency of the decorative block 91 and increasing the error of the installation of the decorative block 91. Although the joints can be reduced if welded joints are used, too many welded joints will increase the welding deformation of the structure, and even affect the appearance of the decorative block 91 in severe cases. In addition, the decorative block 91 is usually large in tonnage and has an irregular structure. The structural strength of this irregular structure is relatively weak. In order to ensure the stability of the structure, there are usually complex steel structures inside the structure. Therefore, when cutting the blocks, in addition to meeting the lifting weight of the tower crane, it is usually necessary to take into account the setting of the internal reinforcement structure of the decorative block 91 to ensure that the structural strength of each segment after cutting is stable during the hoisting process. Therefore, how to divide the decorative block 91 into segments becomes very difficult, and the more the number of cuts, the greater the difficulty. Therefore, from various construction perspectives, the technical solution of the present application is highly innovative and can solve the defects existing in the prior art.
[0040] In the present application, a hook 3 is provided at a lifting point on the pulley block, and a lifting ear 910 is fixed on the decorative block 91. The hook 3 is effectively connected to the decorative block 91 through the lifting ear 910, which is convenient to use and reliable for lifting.
[0041] In the present application, due to factors such as the weight and size of the decorative block 91, the decorative block 91 may need to be moved to the site lying on its side on the transport equipment. At this time, in order to facilitate lifting, the decorative block 91 needs to be turned over. Therefore, the lifting system of the decorative block 91 also includes a swinging steel wire rope 4, which is used to connect with the decorative block 91. After the decorative block 91 is transported to a specific location, during actual operation, the staff connects one end of the swinging steel wire rope 4 to the decorative block 91, and the other end is directly pulled by the staff to assist in adjusting the posture of the decorative block 91. As the winch 1 pulls the steel wire rope, the decorative block 91 is gradually turned over. During the process, the swinging steel wire rope 4 can be pulled to realize the turning process, thereby improving construction efficiency.
[0042] In the present application, the lifting system of the decorative block 91 also includes a leg system 5, which is used to be erected on the main tower 90, and there are two symmetrically distributed leg systems 5. The leg system 5 is a main force-bearing component, which needs to bear the deadweight and hoisting load of the tower top lifting device and transfer it to the main tower 90. The leg system 5 is a truss-type structure assembled by steel sections. In addition, for the main tower 90 with a tower top gantry, the tower top gantry can be directly used as the leg system 5.
[0043] In the present application, a longitudinal movement system is also provided on the leg system 5, and the longitudinal movement system is used to drive the frame system to move on the leg system 5 to meet the longitudinal movement of the decorative block 91 in the longitudinal direction of the bridge, so that the decorative block 91 can be hoisted to the designed position for installation. The leg system 5 is cantilevered from the edge of the main tower 90, which can effectively disperse and bear the load from the upper structure of the leg system 5, including the dead load and the live load. This dispersion effect helps to reduce the force concentration of the main tower 90 and improve the stability and safety of the overall structure. It can also provide more convenience for construction. For example, it can provide a better working platform for construction equipment and personnel, and facilitate the erection, installation and commissioning of the longitudinal movement system.
[0044] In the present application, the frame system provided includes: a distribution beam 60, a Bailey beam 61 and a fixed pulley distribution beam 6260, the distribution beam 60 is movably connected to the support leg system 5, and the distribution beam 60 moves along the longitudinal direction of the bridge; two Bailey beams 61 are provided, and are distributed on the distribution beam 60 along the transverse direction of the bridge, and two winches 1 are distributed on each Bailey beam 61; the fixed pulley distribution beam 6260 is connected to the bottom of the Bailey beam 61, and the fixed pulley group 20 and the reversing fixed pulley 22 are distributed on the fixed pulley distribution beam 6260.
[0045] The distribution beam 60 is a key component in the frame system. Through its mobility and load-bearing capacity, the distribution beam 60 provides flexibility and stability for the entire frame system, ensuring that the load can be safely and evenly transferred to the Bailey beam 61 below. The Bailey beam 61 is a beam that spans across a building or bridge and serves as a lateral support. In this frame system, the Bailey beam 61 is the main load-bearing component responsible for supporting the distribution beam 60 and the load thereon. There are two Bailey beams 61, which are distributed on the distribution beam 60 along the transverse bridge direction. This distribution method ensures that the load can be evenly distributed on the two Bailey beams 61, thereby improving the load-bearing capacity of the system. At the same time, the two winches 1 distributed on each Bailey beam 61 provide power support for the movement and adjustment of the winch 1. The fixed pulley distribution beam 6260 is connected to the bottom of the Bailey beam 61, and the fixed pulley block 20 distributed thereon plays the role of changing the direction of force and transferring load, so that the winch 1 can more conveniently apply tension or thrust, thereby realizing the movement and installation adjustment of the decorative block 91. In the frame system, the distribution beam 60, the Bailey beam 61 and the fixed pulley distribution beam 6260 together constitute a stable, flexible and efficient load-bearing and transmission system. The synergy between them ensures the stability and safety of the entire system when bearing loads.
[0046] The frame system also includes a connection system 63, which is connected between the two Bailey beams 61 along the longitudinal bridge direction. Thus, a more stable frame structure is formed. This connection not only enhances the interaction force between the Bailey beams 61, but also improves the anti-overturning and anti-torsion capabilities of the entire frame system. When subjected to external loads, the connection system 63 can effectively disperse and transfer the load to ensure the overall stability of the frame system. In addition, the design of the connection system 63 also takes into account the convenience of construction and maintenance. During the construction of the frame system, the connection system 63 can be used as a temporary support or positioning device to help construction personnel more accurately install and adjust the position of the Bailey beam 61. At the same time, in the subsequent maintenance and overhaul process, the connection system 63 can also be used as a channel or platform for inspection and repair, providing more convenient working conditions for construction personnel.
[0047] In the present application, the longitudinal shift system provided includes: a reaction seat 70, a through-hole jack 71 and bolt steel. The reaction seat 70 is installed on the leg system 5; the through-hole jack 71 is installed on the reaction seat 70, and one end of the threaded steel bar 72 passes through the reaction seat 70 and the through-hole jack 71, and is connected with an anchor nut 73, and the other end of the threaded steel bar 72 passes through the distribution beam 60 and is connected with an anchor nut 73. By installing the reaction seat 70 on the leg system 5, it can serve as a support and fixing base for the through-hole jack 71, and provide a stable reaction point when in use to support and transmit the thrust or tension generated by the through-hole jack 71, driving the winch 1 in the longitudinal shift process. The reaction seat 70 ensures that the jack can work stably without causing system failure due to uneven force or instability. The through-hole jack 71 is the core component of the longitudinal shift system, which drives the distribution beam 60 to move in the longitudinal direction by generating thrust or tension. When the through-hole jack 71 works, it pushes or pulls the threaded steel 72, thereby driving the entire frame system to move. The thrust or pull of the through-hole jack 71 can be achieved by adjusting its internal pressure to adapt to different movement requirements. The threaded steel 72 serves as a connector, responsible for transmitting the thrust or pull generated by the through-hole jack 71 to the distribution beam 60, thereby driving the entire frame to move, and through the anchor nuts 73 at both ends, the threaded steel 72 is firmly fixed to the reaction seat 70 and the distribution beam 60, ensuring the stability and safety of the system.
[0048] Therefore, the reaction seat 70, the through-hole jack 71 and the bolt steel in the longitudinal movement system work together to achieve stable movement of the frame in the longitudinal direction, which not only ensures the safety and stability of the system, but also improves the flexibility and adaptability of the entire frame system.
[0049] In the present application, in order to improve the stability of the movement of the distribution beam 60, a slider 80 is also provided at the bottom of the distribution beam 60, and a slide groove 81 adapted to the slider 80 is provided on the leg system 5. The slider 80 is connected in the slide groove 81. The matching design of the slider 80 and the slide groove 81 enables the distribution beam 60 to achieve smooth movement on the leg system 5.
[0050] In the present application, in order to further improve the bearing capacity and stability of the distribution beam 60, the distribution beam 60 provided includes a transverse distribution beam 600 and a longitudinal distribution beam 601, wherein the longitudinal distribution beam 601 is connected to the slider 80, and the transverse distribution beam 600 is connected to the longitudinal distribution beam 601. The transverse distribution beam 600 is usually arranged along the transverse direction of the bridge, and its main function is to bear and distribute the transverse load from the upper structure. It is evenly transferred to the longitudinal distribution beam 601 or the leg system 5 below through the transverse distribution beam 600. The longitudinal distribution beam 601 is arranged along the longitudinal direction of the bridge and intersects the transverse distribution beam 600 vertically. It is responsible for bearing and distributing the longitudinal load from the transverse distribution beam 600, as well as loads that may come from other directions. The longitudinal distribution beam 601 is usually connected to the slider 80, and the entire frame system is adjusted in the longitudinal direction by moving the slider 80 in the slide 81. Through the arrangement of the transverse and longitudinal distribution beams 601, the frame system can effectively distribute and transfer the load from the upper structure. This distribution method ensures that each component can bear a reasonable load, thereby improving the bearing capacity and stability of the entire system. When the present application is used in construction, four hooks 3 are respectively corresponding to the bottom of the four winches 1, and the wire rope towed by the winch 1 adopts a special rope winding method to ensure that the large-tonnage special-shaped decorative block 91 is in a state of four-point lifting and three-point balance during lifting. Before the decorative block 91 is officially lifted, after the decorative block 91 is transported to a specific position, the wire rope hook 3 is connected to the lifting ear 910 of the side-lying decorative block 91. As the winch 1 pulls the wire rope, the decorative block 91 is gradually turned over. During the process, the wire rope 4 can be pulled and swung to achieve the stability of the turning process to ensure that the lifting decorative block 91 is ready in a vertical posture.
[0051] This application takes the installation of the decorative block 91 on the side span of the upper crossbeam 92 as an example, and uses a lifting system to lift it above the upper crossbeam 92, and then moves it from the middle span side to the side span side by longitudinal movement, and finally moves it to the designed position by lowering it for installation. The specific steps are: use the hook 3 to connect with the lifting ear 910 of the decorative block 91, and then drive the winch 1 to pull the wire rope to lift the decorative block 91 above the upper crossbeam 92, and then drive the through-core jack 71 to generate thrust or tension to drive the distribution beam 60 to move in the longitudinal direction. When the through-core jack 71 is working, it will push or pull the threaded steel bar 72, thereby driving the entire frame system to move until the decorative block 91 is moved to the designed position and installed.
