The front end of the sling 4 is connected with a hook 5. The above technical solution uses a movable base 1, a support frame 2, and a winch 3 to form the main lifting working structure. Since the three are all detachably connected and the support frame 2 is spliced by multiple components, the entire construction structure has the characteristics of being easy to disassemble and install, which is convenient for disassembly and transportation to various working environments. The overall structure of the structure is simple and the component size is small, so it is also suitable for some narrow working environments. At the same time, the movable base 1 can enable the structure to move freely within a certain range when in use, thereby improving work efficiency.

[0024] Specifically, refer to Figure 2 Several groups of hinged seats 26 are fixedly provided on the front end surface of the main support rod 21, and several groups of hinged seats 26 are fixedly provided on the lower end surface of the cantilever secondary support 22. The main support rod 21 and the cantilever secondary support 22 are connected with an oblique support rod 27 through the hinged seat 26, and the hinged seat 26 and the oblique support rod 27 are hinged through a pin shaft 23. By adopting the above technical solution, the angle between the main support rod 21 and the cantilever secondary support 22 can be adjusted in a way that the oblique support rod 27 is respectively connected to different hinged seats 26 on the main support rod 21 and the cantilever secondary support 22, thereby changing the height of the front end of the cantilever secondary support 22, that is, the maximum height of the component can be lifted.

[0025] Specifically, refer to Figure 2The main support rod 21 is provided with several short hollow grooves 28, and the cantilever secondary support 22 is provided with a long hollow groove 28 in the middle. The above-mentioned structural form can reduce the dead weight of the structure by setting the hollow grooves 28, thereby facilitating the installation, disassembly and transportation of the components, and at the same time can ensure that the components have a larger external cross-sectional area and ensure the overall rigidity of the components.

[0026] Specifically, refer to Figure 2 A reinforcement frame 29 is fixedly connected between the front end surface of the bottom of the main support rod 21 and the upper end surface of the movable base 1. The reinforcement frame 29 and the main support rod 21 are fixedly connected by bolts, and the reinforcement frame 29 and the movable base 1 are fixedly connected by bolts. By adopting the above technical solution, it can support the main support rod 21, share the load, and also improve the overall stability through the triangular structural characteristics.

[0027] Specifically, refer to Figure 3-4 The movable base 1 includes a mounting base 11, and universal wheels 12 are fixedly installed at the four corners of the lower end surface of the mounting base 11.

By adopting the above technical solution, the movable base 1 is made pushable by setting the universal wheel 12, which is convenient for lifting operation. At the same time, the wheel locking bolts 121 can lock the universal wheel 12 so that it cannot rotate, thereby fixing the position. In addition, the auxiliary support mechanism 13 can share the vertical load by contacting the supporting surface, making the overall structure more stable, and the counterweight block 14 can balance the torque generated by the lifting component to prevent the construction structure from tipping forward.

[0028] Specifically, refer to Figure 4The auxiliary support mechanism 13 includes a threaded rod 131, which is engaged with the threaded hole on the mounting base 11 through a threaded meshing connection. A handle 132 is fixedly provided on the top side of the threaded rod 131, a contact pad 133 is provided at the bottom of the threaded rod 131, and an anti-slip component 134 is fixedly provided on the upper end surface of the contact pad 133. A T-shaped hole is provided at the bottom of the threaded rod 131, and the threaded rod 131 and the contact pad 133 are movably connected by snapping the anti-slip component 134 into the T-shaped hole. A hollow groove 135 is provided in the middle of the threaded rod 131. By adopting the above technical solution, Through the threaded connection, when the threaded rod 131 is rotated by the handle 132, the bottom end of the threaded rod 131 can gradually move downward, so that the contact pad 133 contacts the support surface, and then the bottom end of the threaded rod 131 presses against the contact pad 133 to start sharing the vertical load, which can improve the stability of the structure. At the same time, the contact pad 133 can also provide greater friction and improve the anti-slip ability of the structure. In particular, due to the movable connection between the threaded rod 131 and the contact pad 133, the contact pad 133 will not be driven to rotate during the rotation of the threaded rod 131, which is convenient to use.
