[0025] Currently, the widely adopted hoisting schemes in the market mostly rely on traditional cranes cooperating with steel wire ropes or hoisting belts for operation. Although these methods meet the construction requirements to a certain extent, they have the following obvious disadvantages. After the cantilever steel structure member is hoisted to the installation position, its position and angle need to be adjusted. However, due to the large weight of the cantilever steel structure member, it is difficult to control the suspended installation posture of the member by traditional hoisting methods, and it takes multiple times and a long time to adjust it correctly, increasing the risk of falling during the construction process and affecting the overall construction progress.

[0026] Therefore, it is particularly important to develop a hoisting device that can adjust the installation attitude of the cantilever steel structure members and assist in the installation of the cantilever steel structure members.

[0027] The design concept of this application is to design a hoisting device that can avoid the suspension of the cantilever steel structure members during hoisting and can rotate and lift to adjust the installation attitude, position and angle.

[0028] As Figure 1 shown, this application provides a hoisting device for high-altitude cantilever steel structure members, including a crossbeam mechanism. The crossbeam mechanism is detachably connected with a longitudinal beam mechanism. A hoisting trolley 5 and an adjustment trolley 6 are arranged on the longitudinal beam mechanism. A rotating mechanism is arranged on the adjustment trolley 6. The rotating mechanism is connected with a lifting mechanism. The lifting mechanism is connected with a bearing platform 11.

[0029] Among them, the crossbeam mechanism includes a crossbeam base 2 installed on the building exterior wall 1. A slide rail 3 is arranged on the crossbeam base 2. The crossbeam base 2 is detachably connected with the longitudinal beam mechanism. The slide rail 3 is slidably connected with the longitudinal beam mechanism.

[0030] During installation, the crossbeam base 2 is horizontally fixed on the upper part of the building exterior wall 1 by using connecting parts such as anchor bolts, and then the longitudinal beam mechanism is slidably connected to the slide rail 3.

[0031] Among them, the longitudinal beam mechanism includes a wall-mounted jib crane. The wall-mounted jib crane includes a beam body 4, a hoisting trolley 5 and an adjustment trolley 6. A longitudinal beam base 7 and a chute 8 are arranged at the end of the beam body 4. The longitudinal beam base 7 is detachably connected with the crossbeam base 2. The chute 8 is slidably connected with the slide rail 3. A winch is arranged on the hoisting trolley 5. The winch is connected with a hook.

[0032] During installation, the chute 8 is slidably connected with the slide rail 3, and then the longitudinal beam base 7 and the crossbeam base 2 are connected by using connecting parts such as anchor bolts. The anchor bolts can pass through the longitudinal beam base 7 and the crossbeam base 2 in sequence and be installed on the upper part of the building exterior wall 1.

[0033] The finished wall-mounted jib crane is directly purchased for the longitudinal beam mechanism, which is more conducive to the rapid completion of the scheme research and development. Two moving trolleys are installed on the wall-mounted jib crane, namely the hoisting trolley 5 and the adjustment trolley 6. Among them, the hoisting trolley 5 is used to hoist the cantilever steel structure member 12 to the installation position, and the adjustment trolley 6 is used for the installation attitude of the cantilever steel structure member 12.

[0034] Among them, the rotating mechanism includes an electric turntable 9. The electric turntable 9 is connected with the lifting mechanism. The lifting mechanism includes a hydraulic jack 10. The hydraulic jack 10 is connected with the bearing platform 11.

[0035] During use, the electric turntable 9 rotates the hydraulic jack 10, and the hydraulic jack 10 rotates the cantilever steel structure member 12 to adjust the installation angle of the cantilever steel structure member 12; the hydraulic jack 10 moves the bearing platform 11 up and down, and the bearing platform 11 moves the cantilever steel structure member 12 up and down to adjust the installation position of the cantilever steel structure member 12.

[0036] In the use of this application, the crossbeam base 2 is horizontally fixed to the upper part of the building exterior wall 1 by using connecting pieces such as anchor bolts. The chute 8 is slidably connected to the slide rail 3. The longitudinal beam base 7 is installed on the upper part of the building exterior wall 1 by sequentially passing connecting pieces such as anchor bolts through the longitudinal beam base 7 and the crossbeam base 2. The hoisting trolley 5 is started, and the cantilever steel structure member 12 is hoisted to the installation position. The hydraulic jack 10 extends, and the bearing platform 11 descends to the lower part of the cantilever steel structure member 12. The adjustment trolley 6 is started, and the bearing platform 11 moves to the bottom of the cantilever steel structure member 12. The hydraulic jack 10 rises, and the cantilever steel structure member 12 lands on the bearing platform 11. The electric turntable 9 is started to rotate the cantilever steel structure member 12 to a suitable installation angle. The adjustment trolley 6 is started, and the cantilever steel structure member 12 moves to contact the building exterior wall 1. Workers install the cantilever steel structure member 12. After the installation is completed, the anchor bolts of the longitudinal beam base 7 and the crossbeam base 2 are removed, and the longitudinal beam base 7 is pushed to slide on the crossbeam base 2 until the next installation location. The longitudinal beam base 7 is installed on the upper part of the building exterior wall 1 by sequentially passing connecting pieces such as anchor bolts through the longitudinal beam base 7 and the crossbeam base 2. The above-mentioned hoisting and installation of the cantilever steel structure member 12 are repeated until the construction is completed.
