Description

Technical Field

[0001] This application relates to the technical field of aerial work platforms, and in particular to a combined cable lifting device for hoisting the deck of a basket arch bridge. Background Technology

[0002] With the continuous development of bridge construction technology, basket arch bridges, due to their beautiful shape and excellent mechanical properties, are widely used in long-span bridge projects. The bridge deck, as the main load-bearing component of a basket arch bridge, requires cable-stayed installation.

[0003] The cable lifting equipment includes a cable lifting main rope and a balance beam. The balance beam is slidably installed on the cable lifting main rope. The balance beam is attached with a shackle and a chain. One end of the chain is fastened to the shackle and the shackle, and the other end of the chain is connected to a hook. The hook is attached to the lifting ring on the bridge deck. The number of chains is installed according to the size of the bridge deck to ensure that the bridge deck can be stably lifted and transported.

[0004] Regarding the aforementioned technologies, after the bridge deck is hoisted to the designated position, the lifting equipment must return along the same route to continue hoisting. At this time, multiple chains may become entangled while moving at high altitudes. Utility Model Content

[0005] To improve the above situation, this application provides a combined basket arch bridge deck hoisting cable lifting device.

[0006] This application provides a combined basket arch bridge deck hoisting cable lifting device, which adopts the following technical solution: A combined basket arch bridge deck hoisting cable lifting device includes: Main rope; The balance beam is attached to and slidably installed on the main rope. Chains, attached to the balance beam, can be detachably installed in multiples; A hook is fixedly installed on the chain; A connecting block is installed on the chain and close to the hook. The connecting blocks of multiple chains are detachably connected to each other so that the multiple chains do not get tangled.

[0007] By adopting the above technical solution, the chain is designed to be detachable, allowing the number of chains (e.g., 4 or 8) to be dynamically adjusted according to the size / weight of the bridge deck. The connecting block forcibly fixes the relative positions of multiple chains, eliminating free swing space.

[0008] Optionally, the connecting blocks are fixed together by magnetic attraction.

[0009] By adopting the above technical solution, magnetic attraction does not require complicated mechanical operation, and workers can quickly connect / disconnect the chain assembly with one hand when working at height.

[0010] Optionally, a connecting rope is connected to the connecting block, and the connecting rope is detachably connected to the other connecting blocks.

[0011] By adopting the above technical solution, the magnetic attraction may fail when the chain spacing is large. The connecting rope can span a greater distance, and hooks or buckles can be used to fix the connecting rope to adjacent connecting blocks, adapting to the hanging point spacing of panels of different sizes.

[0012] Optionally, the connecting block can be detachably installed on the chain.

[0013] By adopting the above technical solution, the connecting block can be disassembled separately when it is damaged or when anti-tangling is not required (such as in single chain operation).

[0014] Optionally, the connecting block has a through-hole, through which the chain passes.

[0015] By adopting the above technical solution, the chain is inserted into the cavity during installation, so that the connecting block is stably positioned above the hook at a preset position.

[0016] Optionally, the connecting block is fitted with a plug rod, which passes through a link of the chain and is then inserted into the connecting block.

[0017] By adopting the above technical solution, the insert rod passes through the chain link and the connecting block to form a rigid connection, preventing the connecting block from moving along the chain.

[0018] Optionally, the insertion rod is provided with a positioning post, the two ends of which are attached to the inner wall of the receiving cavity, and the positioning post is in contact with the chain link.

[0019] By adopting the above technical solution, the positioning column expands the force-bearing surface, increasing frictional resistance.

[0020] Optionally, the connecting block is a two-and-a-half splicing structure, one end of the insert rod passes through one half of the connecting block and is threadedly connected to the other half of the connecting block, and the other end of the insert rod extends out of the connecting block and is threadedly connected to a nut.

[0021] By adopting the above technical solution, the disassembly and installation of the connecting block can be completed more quickly.

[0022] Optionally, positioning grooves are provided at both the upper and lower ends of the connecting block, and some of the chain links are inserted into the positioning grooves.

[0023] By adopting the above technical solution, the positioning column expands the force-bearing surface, increasing frictional resistance.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. Eliminate chain entanglement; 2. Modular design allows for the replacement of only partial components (such as a single chain or connecting block). Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0028] This application discloses a cable lifting device for hoisting the deck of a combined basket arch bridge.

[0029] A combined basket arch bridge deck hoisting cable sling includes a main rope 10, a balance beam 20, and a chain 30. The main rope 10, serving as the load-bearing foundation of the sling, is typically constructed of high-strength steel cable, with both ends fixed to the tower top and anchorage of the cable sling system. The balance beam 20 is connected to and slidably mounted on the main rope 10 via a pulley system, allowing free movement along the axis of the main rope 10. A groove adapted to the pulley system is provided in the middle of the balance beam 20 to ensure smooth sliding.

[0030] The bottom of the balance beam 20 has multiple evenly distributed attachment points, each of which is detachably connected to a chain 30 via a shackle. The number of chains 30 can be adjusted according to the size and weight of the bridge deck, usually 4 or 8. Each chain 30 has a hook 40 fixedly installed at its lower end for attaching to the lifting ring on the bridge deck.

[0031] Refer to 1 and Figure 2To prevent the multiple chains 30 from tangling when moving at heights, a connecting block 50 is installed on each chain 30 near the hook 40. The connecting blocks 50 of the multiple chains 30 are detachably connected by magnetic attraction or connecting ropes. When using magnetic attraction, a permanent magnet is embedded on one side of the connecting block 50, and a magnetically conductive metal plate is provided on the other side. Adjacent connecting blocks 50 are fixed by magnetic attraction.

[0032] Alternatively, a connecting rope can be used for connection. One end of the connecting rope is fixed to one of the connecting blocks 50, and the other end is detachably connected to the adjacent connecting block 50 by means of hooks, buckles, or binding.

[0033] Reference Figure 3 and Figure 4 The connecting block 50 is detachably installed on the chain 30. The specific structure is as follows: the connecting block 50 has a through cavity 51, through which the chain 30 passes. At the same time, the connecting block 50 is inserted with a rod 60. One end of the rod 60 passes through the chain link of the chain 30 and is threaded to the side wall of the connecting block 50. The other end of the rod 60 extends out of the connecting block 50 and is threaded to a nut 61, which further enhances the connection stability between the connecting block 50 and the chain 30.

[0034] Reference Figure 3 Furthermore, the connecting block 50 is a two-and-a-half spliced ​​structure, fixed by magnetic attraction. The insert rod 60 passes through one half of the connecting block 50 and is threadedly connected to the other half. Positioning grooves 52 are provided at both the upper and lower ends of the connecting block 50, and some chain links are inserted into the positioning grooves 52 to restrict the axial movement of the connecting block 50 along the chain 30. When removing the connecting block 50, the insert rod 60 is pulled out of the connecting block 50, thus disassembling the connecting block 50 in half.

[0035] Reference Figure 4 and Figure 5 The insertion rod 60 is also provided with a positioning post 70. The two ends of the positioning post 70 are attached to the inner wall of the receiving cavity 51 and in contact with the chain link. By increasing the contact area, the friction is increased to prevent the connecting block 50 from shaking.

[0036] The implementation principle of a cable-stayed lifting device for hoisting the deck of a combined basket arch bridge according to an embodiment of this application is as follows: In actual operation, the required number of chains 30 is first determined according to the specifications of the bridge deck, and the chains 30 are then attached to the balance beam 20 using shackles. Next, connecting blocks 50 are installed on the chains 30 near the hook 40 and secured using insert rods 60 and positioning posts 70. Then, magnetic attraction or connecting ropes are used to connect the connecting blocks 50 of adjacent chains 30, forming a stable whole. During hoisting, the balance beam 20 moves along the main rope 10 above the bridge deck, and after the hook 40 engages with the lifting ring of the bridge deck, the bridge deck is lifted and transported to the designated location. After hoisting, when the lifting equipment returns, the connecting blocks 50 maintain a relatively fixed position for the multiple chains 30, effectively preventing entanglement. When it is necessary to replace a chain 30 or connecting block 50, simply disconnect the shackles or insert rods 60 to disassemble and replace the damaged parts individually, achieving modular maintenance of the lifting equipment.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
