[0002] During the building construction process, it is often necessary to use a lifting device to lift horizontally arranged members (such as steel pipes, columns, etc.) to a vertical state.
[0003] For example, during the foundation reinforcement process, workers need to weld several sections of steel pipes into a longer steel pipe and press the steel pipe into the soil to improve the bearing capacity of the foundation. Specifically, the workers lift the horizontally placed steel pipe to a vertical state, then weld and fix the steel pipe in the air to the steel pipe pressed into the soil, and finally use a pressing device (such as a percussion hammer) to press the steel pipe in the air into the soil.
[0004] In the above construction process, the lifting ring of the lifting device (or a hook with a safety catch) needs to be connected to the upper end of the steel pipe to lift the steel pipe from a horizontal state to a vertical state. After the lower end of the steel pipe is welded and fixed to the steel pipe buried in the soil, it is necessary to separate the lifting ring of the lifting device from the steel pipe to facilitate the percussion hammer to press the steel pipe into the soil.

During the foundation reinforcement process, the staff needs to weld several sections of steel pipes 1 into a longer steel pipe 1 and press the steel pipe 1 into the soil to improve the bearing capacity of the foundation.
[0039] Refer to Figure 1 . Specifically, the staff hoists the horizontally placed steel pipe 1 to a vertical state, then welds and fixes the steel pipe 1 in the air to the steel pipe 1 pressed into the soil body, and finally uses a pressing device (such as a percussion hammer) to press the steel pipe 1 in the air into the soil.
[0040] Refer to Figure 1 . During the above construction process, the lifting tackle 2 (lifting ring or hook with safety catch) of the lifting equipment needs to be connected to the upper end of the steel pipe 1 to hoist the steel pipe 1 from a horizontal state to a vertical state. After the lower end of the steel pipe 1 is welded and fixed to the steel pipe 1 buried in the soil body, the lifting ring of the lifting equipment needs to be separated from the steel pipe 1 to facilitate the percussion hammer to press the steel pipe 1 into the soil. Since there is a large distance between the upper end of the steel pipe 1 and the ground, when the staff separates the lifting ring of the lifting equipment from the steel pipe 1, it is necessary to work at a high altitude with the help of a climbing ladder, a lifting equipment, etc. to separate the hook from the steel pipe 1, so there are construction safety hazards. Based on the above technical problems, the present application proposes a solution for the quick release device for hoisting a vertical member to solve the above technical problems.
[0041] Refer to Figures 2 to 4 . The quick release device for hoisting a vertical member includes an arc-shaped member 3, a first cylinder 4, a second cylinder 5, a sliding rod 6, a connecting rod 7, a steel strand 8 and a guiding assembly 9.
[0042] Refer to Figure 3 and Figure 4 .

[0044] Refer to Figure 4 and Figure 5 At the same time, a limiting member 51 is also provided on the inner peripheral wall of the second cylinder 5. The limiting member 51 is fixed on the side of the second cylinder 5 away from the first cylinder 4. The limiting member 51 is used to abut against the sliding rod 6; the limiting member 51 is used to limit the sliding of the sliding rod 6 out of the first cylinder 4 and the second cylinder 5. The limiting member 51 can be a blocky substance such as a metal block or a rubber block. The limiting member 51 can be fixedly adhered to the second cylinder 5 by welding, bonding or other means. In this embodiment, the limiting member 51 is a small steel plate, and the small steel plate is fixedly welded to the inner peripheral wall of the second cylinder 5.
[0045] Refer to Figure 3 , Figure 4 and Figure 6 The connecting rod 7 passes through the communication hole 41 on the first cylinder 4. One end of the connecting rod 7 is fixedly connected to the sliding rod 6, and the other end of the connecting rod 7 is fixedly connected to the steel strand 8. The staff can push and pull the connecting rod 7 to pass the sliding rod 6 through the hanging hole 11 of the vertical rod and insert the end of the sliding rod 6 into the second cylinder 5. In this embodiment, the connecting rod 7 is provided with an external thread near the end of the sliding rod 6, and the sliding rod 6 is provided with an internal thread near the end of the connecting rod 7 that matches the external thread of the connecting rod 7. The connecting rod 7 is threadedly connected to the sliding rod 6; and a nut 71 is welded to the end of the connecting rod 7 away from the first cylinder 4, and the nut 71 is fixedly bound to the steel strand 8 to facilitate the construction of the staff.
[0046] Refer to Figure 3 and Figure 4 When the vertical rod is hoisted, the hanging hole 11 of the vertical rod is on the moving path of the sliding rod 6. After the sliding rod 6 passes through the hanging hole 11, it is inserted into the second cylinder 5; when the hoisting of the vertical rod is completed, the steel strand 8 forces the sliding rod 6 to slide towards the direction close to the first cylinder 4, and the sliding rod 6 is separated from the second cylinder 5 and the vertical rod.
[0047] Refer to Figure 3 and Figure 4, the guiding assembly 9 includes a guiding rod 91, a first fixed pulley 92 and a second fixed pulley 93. The guiding rod 91 is fixedly connected to the first cylinder 4, and the central axis of the guiding rod 91 is arranged parallel to the central axis of the first cylinder 4.

Moreover, the second fixed pulley 93 and the first cylinder 4 are arranged on both sides of the guiding rod 91. After one end of the steel strand 8 is fixed to the connecting rod 7, the steel strand 8 is successively wound around the first fixed pulley 92 and the second fixed pulley 93, and the other end of the steel strand 8 is arranged on the ground.
[0048] By arranging the guiding assembly 9 to guide and limit the steel strand 8, it is convenient for the staff to pull the steel strand 8; and the central axis of the guiding rod 91 is arranged parallel to the central axis of the first cylinder 4, so that it is convenient for the steel strand 8 to pull the sliding rod 6 to slide. At the same time, by arranging the second fixed pulley 93, the limiting effect of the second fixed pulley 93 on the steel strand 8 is utilized to reduce the risk of the steel strand 8 disengaging from the first fixed pulley 92 and the second fixed pulley 93, and improve the operating stability of the quick-release device.
[0049] The implementation principle of the quick-release device for vertical member hoisting in the embodiment of the present application is as follows:
[0050] Refer to Figure 4 , when the steel pipe 1 is horizontally arranged, the staff installs the quick-release device on the steel pipe 1 and fixedly connects the lifting tool 2 of the lifting equipment to the arc-shaped member 3. At this time, the hanging hole 11 of the vertical member is located on the moving path of the sliding rod 6. After the sliding rod 6 passes through the hanging hole 11, it is inserted into the second cylinder 5. That is, the sliding rod 6 is arranged in the first cylinder 4 and the second cylinder 5, and the sliding rod 6 passes through the hanging hole 11 of the steel pipe 1, and the sliding rod 6 plugs the notch 31 of the arc-shaped member 3, so that the lifting tool 2 is fixedly connected to the steel pipe 1 through the quick-release device, that is, the fixed connection between the steel pipe 1 and the lifting tool 2 is realized.
[0051] Refer to Figure 6 , when the vertical member hoisting is completed, the staff pulls the steel strand 8 on the ground, so that the steel strand 8 forces the sliding rod 6 to slide towards the direction close to the first cylinder 4, and the sliding rod 6 is separated from the second cylinder 5 and the vertical member. Thus, the steel pipe 1 can pass through the notch 31 of the arc-shaped member 3, so that the steel pipe 1 is separated from the quick-release device and the lifting tool 2, which is convenient for the impact hammer to press the steel pipe 1 into the soil.
[0052] That is, by arranging a quick-release device between the steel pipe 1 and the lifting tool 2, the quick separation between the steel pipe 1 and the lifting tool 2 is realized, reducing the operation of the staff at high altitude and improving the construction safety.
[0053] Embodiment 2
[0054] The difference between this Embodiment 2 and Embodiment 1 lies in that:
[0055] Referring to Figure 7 , the quick-release device further includes a spring 10. The spring 10 is arranged in the first cylinder 4, and the spring 10 is arranged between the bottom wall of the first cylinder 4 and the sliding rod 6. The spring 10 is used to force the sliding rod 6 to slide and be inserted into the second cylinder 5. During the hoisting process of the vertical rod member, the spring 10 forces the sliding rod 6 to be inserted into the second cylinder 5, thereby improving the operation stability of the quick-release device and the safety of the steel pipe hoisting.
