[0002] During the construction of the ground-anchored wall, the steel cage needs to be hoisted into the dug hole. When hoisting, the steel cage needs to be placed upright in a flat state, and then slowly hoisted into the hole.

[0003] However, since the steel cage used in the ground-anchored wall is relatively long, lifting it directly at one end will easily cause the steel cage to bend and deform, making it difficult to enter the hole. Therefore, the existing method usually uses two cranes to cooperate, one crane is connected to the end of the steel cage, and the other is connected to the middle of the steel cage. Through the cooperation of the two cranes, the steel cage is lifted from a flat state to an upright position, and then hoisted into the hole, and the connection between the crane and the middle of the steel cage is released at the same time.

[0032] The ground-connected wall reinforcement cage lifting device provided by the utility model is now described.

[0033] like Figure 1 As shown, the first embodiment of the utility model provides a ground-connected wall reinforcement cage lifting device, including a body 10, a boom 20, a main lifting pulley block 31, a main lifting drive 32, a main lifting cable 33, a main lifting device 34, an auxiliary lifting pulley 41, an auxiliary lifting drive 42, an auxiliary lifting cable 43 and an auxiliary lifting device 44, the boom 20 is arranged on the body 10; the main lifting pulley block 31 is arranged on the boom 20; the main lifting drive 32 is arranged on the body 10; the main lifting cable 33 passes through the main lifting pulley block 31, and one end is connected to the main lifting driver 32; the main hoisting device 34 is arranged on the other end of the main lifting cable 33, and is used to connect with one end of the steel cage; the auxiliary lifting pulley 41 is arranged on the boom 20; the auxiliary lifting driver 42 is arranged on the body 10; the auxiliary lifting cable 43 passes through the auxiliary lifting pulley 41, and one end is connected to the auxiliary lifting driver 42; the auxiliary hoisting device 44 is arranged on the other end of the auxiliary lifting cable 43, and is used to connect with the middle part of the steel cage.

[0034] When in use, the main hoist 34 is connected to one end of the steel cage, and the auxiliary hoist 44 is connected to the middle of the steel cage, and then the main hoisting cable 33 and the auxiliary hoisting cable 43 are pulled by the main lifting driver 32 and the auxiliary lifting driver 42 respectively to lift the steel cage steadily until the steel cage stands up; then, the steel cage is moved to the top of the hole by the cooperation of the machine body 10 and the boom 20, and the main hoisting cable 33 and the auxiliary hoisting cable 43 are released by the main lifting driver 32 and the auxiliary lifting driver 42 respectively to gradually put the steel cage into the hole, and the connection between the auxiliary hoist 44 and the main hoist 34 and the steel cage is released according to the state of the steel cage to complete the lifting.

[0035] Compared with the prior art, the ground-anchored wall reinforcement cage lifting device provided in this embodiment has a main lifting pulley group 31 and an auxiliary lifting pulley 41 simultaneously arranged on the boom 20, and a main lifting driver 32 and an auxiliary lifting driver 42 are simultaneously arranged on the body 10, and in combination with the main lifting cable 33, the main lifting device 34, the auxiliary lifting cable 43 and the auxiliary lifting device 44, so that the reinforcement cage can be lifted with one device, and one driver can operate the main lifting driver 32 and the auxiliary lifting driver 42, which can greatly reduce the requirements for site size and on-site scheduling, and reduce the consumption of manpower and material resources, and there is no interference between cranes, which is conducive to eliminating or reducing safety hazards in construction.

[0036] like Figures 2 to 4 As shown, the utility model provides a specific implementation method based on the first implementation method as follows:

[0037] like Figure 2 As shown, a cross bar 21 is provided on the top of the boom 20, and a main lifting pulley block 31 includes two main pulleys, which are respectively rotatably arranged at both ends of the cross bar 21 to prevent the main hoisting cable 33 and the auxiliary hoisting cable 43 from affecting each other; the boom 20 and the cross bar 21 are both truss structures to improve the strength of the boom. In order to improve the flexibility of use, the cross bar 21 can be divided into two sections, and they are respectively connected to the boom 20 for rotation and limiting.

[0038] like Figure 3 As shown, in some specific embodiments, the auxiliary hoist 44 includes a leveling pulley assembly 441 and a leveling rope 442, and the leveling pulley assembly 441 is connected to the auxiliary hoist cable 43; the middle part of the leveling rope 442 passes around the leveling pulley assembly 441, and the two ends are respectively used to connect with different positions in the middle of the steel cage.

[0039] This structure can increase the lifting points on the steel cage, and during the lifting process, the length of the leveling ropes 442 on both sides can be adjusted by the leveling pulley assembly 441 to reduce the possibility of deformation of the steel cage; and in order to further reduce the possibility of deformation of the steel cage, multiple leveling ropes 442 can be set, and for each additional leveling rope 442, two lifting points can be added to the steel cage.

[0040] Furthermore, a damping structure is provided on the leveling pulley assembly 441, and the auxiliary sling 44 further includes two traction ropes 443, both of which are connected to the leveling rope 442, and the connection points are respectively located on both sides of the leveling pulley assembly 441. In this way, the length of the leveling rope 442 on both sides of the leveling pulley assembly 441 can be adjusted by pulling the corresponding traction rope 443 on the ground, thereby reducing the possibility of deformation of the steel cage.

[0041] Specifically, the leveling rope 442 is connected to the steel cage through components such as a lifting ring, a fastener or a self-releasing hook. At the same time, in order to reduce the local deformation of the steel cage at the lifting point, the lifting point position can be reinforced in advance.

[0042] like Figure 4 As shown, in some specific embodiments, the main hoist 34 includes a hanging plate 341 and a plurality of elastic connection components, the hanging plate 341 is connected to the main hanging cable 33; the plurality of elastic connection components are distributed on the hanging plate 341 and are respectively connected to different steel bars at the ends of the steel cage.

[0043] Furthermore, the elastic connection assembly includes an elastic member 342, an extended suspension rope 343 and a connecting member 344, one end of the elastic member 342 is connected to the edge of the suspension plate 341; one end of the extended suspension rope 343 is connected to the other end of the elastic member 342; the connecting member 344 is connected to the other end of the extended suspension rope 343 for connecting to the steel bars at the end of the steel cage.

[0044] Specifically, the elastic member 342 is a spring component; a protective sleeve is provided outside the elastic member 342 to prevent adjacent elastic members 342 from being entangled.

[0045] Furthermore, the elastic member 342 includes a strong spring and a weak spring connected in series. Under the same force conditions, the elongation of the strong spring is less than the elongation of the weak spring. In this way, the weak spring can be used to obtain a larger elongation, so that the overall elongation is larger, making the force on each elastic connection component more even.

[0046] Specifically, the connector 344 is connected to the steel cage by hooking, bolting or welding, etc., which can provide a stable connection.

[0047] In order to reduce the possibility of local deformation of the steel cage at the hanging point, the hanging point position can be reinforced in advance.

[0048] In a specific embodiment, the connecting member 344 is a hook or a hanging ring, and a hanging member is pre-welded on the steel cage to cooperate with the connecting member 344.

[0049] In another specific embodiment, the connecting member 344 is a welded rod, and a plurality of connecting rings are welded on the welded rod along the length direction. When in use, the steel bar rod is welded to the steel bar at one end of the steel cage. After all the welded rods corresponding to the elastic connecting components are welded, the extension rope 343 is connected to a suitable connecting ring, so that the length of each elastic connecting component is appropriate to ensure that during lifting, the pulling force applied by the lifting plate 341 to each elastic connecting component is roughly equal, so as to avoid excessive elongation of one or some elastic connecting components and cause danger.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
