[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution: A hoisting device for construction in confined spaces includes a mounting plate 1. Hanging rings 7 are fixedly installed on the left and right sides of the top of the mounting plate 1. Sliding grooves 5 are opened at both ends of the front and rear outer walls of the mounting plate 1. A horizontal moving component 3 is installed inside each set of sliding grooves 5. The horizontal moving component 3 is connected to an adjustment component 6 and a disassembly component 14 respectively. The disassembly component 14 is connected to a hanging lug 4. The adjustment component 6 is connected to a shielding component 2. The mounting plate 1 is I-shaped.

[0021] Furthermore, the horizontal moving component 3 includes threaded rods 32. Four sets of threaded rods 32 are rotatably connected to the inner walls of the left and right sides of the two sets of slide grooves 5 respectively. Each set of threaded rods 32 has a slider 31 threadedly connected to its outer wall. The outer wall of each set of sliders 31 is connected to the easy-to-remove component 14. The end of each set of threaded rods 32 near the left or right end of the mounting plate 1 is connected to the adjusting component 6. The adjusting component 6 can control the rotation of the threaded rods 32 of each component, so that the sliders 31 drive the hanging ears 4 to move along the slide groove 5 through the easy-to-remove component 14 until each set of hanging ears 4 moves to a position that is convenient for hoisting.

[0022] Furthermore, the detachable component 14 includes a limiting groove 142. Four sets of limiting grooves 142 are all opened on the top of four sets of sliders 31, and each set of limiting grooves 142 penetrates the side wall of the slider 31. A limiting block 141 is inserted into the inner wall of each set of limiting grooves 142. The outer wall of each set of limiting blocks 141 is fixedly connected to the hanging ear 4. Both the limiting grooves 142 and the limiting blocks 141 are T-shaped. The insertion connection between the limiting blocks 141 and the limiting grooves 142 facilitates the replacement of hanging ears 4 of different sizes.

[0023] Furthermore, a rectangular plate 13 is fixedly installed on the top of each slider 31 near the entry end of the limiting groove 142. The bottom of the rectangular plate 13 is in contact with the top of the limiting block 141. Loosening the fastening device on the rectangular plate 13 makes it easy to pull out the limiting block 141 with the hanging ear 4 installed.

[0024] Furthermore, the adjustment component 6 includes a circular groove 62. Four sets of circular grooves 62 are respectively opened at the front and rear ends of the left and right sides of the mounting plate 1. The ends of four sets of threaded rods 32 near the circular grooves 62 all penetrate into the interior of the circular grooves 62, and the threaded rods 32 are rotatably connected to the circular grooves 62. Each set of threaded rods 32 has a polygonal groove 61 at the end inside the circular groove 62. The outer wall of the circular groove 62 is connected to the shielding component 2. After opening the shielding component 2, the threaded rods 32 can be rotated by inserting a special polygonal protrusion into the polygonal groove 61, so that the slider 31 drives the hanging ears 4 to move along the slide groove 5 until each set of hanging ears 4 moves to a position that is convenient for hoisting.

[0025] Furthermore, the shielding component 2 includes a rotating shaft 21. Four sets of rotating shafts 21 are evenly fixedly installed on the outer wall of the mounting plate 1 near the outlet of the circular groove 62. Each set of rotating shafts 21 is rotatably connected to a connecting rod 23 on its outer wall. The other end of each set of connecting rods 23 is fixedly installed with a baffle 24. Each set of baffles 24 is in close contact with the outlet end of the circular groove 62. By rotating the connecting rod 23, the baffle 24 is moved away from the outlet end of the circular groove 62, thereby adjusting the polygonal groove 61 on the threaded rod 32.

[0026] Furthermore, a torsion spring 22 is installed at the connection between the connecting rod 23 and the rotating shaft 21. Four sets of stop blocks 25 are evenly fixed on the outer wall of the mounting plate 1. The top of each set of stop blocks 25 is in contact with the bottom of the connecting rod 23. When the stop plate 24 is released, the torsion spring 22 will automatically drive the connecting rod 23 and the stop plate 24 to reset and block the outlet of the circular groove 62. The stop block 25 then restricts the connecting rod 23 from continuing to rotate.

[0027] Furthermore, guide rods 9 are fixedly installed at both the left and right ends of the top of the mounting plate 1. Counterweights 10 are slidably connected to the outer wall of the guide rods 9. When the weight of the object being lifted by the lugs 4 at the left and right ends of the mounting plate 1 is not equal, the mounting plate 1 can be balanced by adding an appropriate amount of counterweights 10.

[0028] Furthermore, each set of sliders 31 has a right-angle block 11 fixedly installed at the bottom. The other right-angle face of each set of right-angle blocks 11 is in contact with the outer wall of the mounting plate 1. When the hanging ear 4 hangs an item, the slider 31 is subjected to the pulling force from below, and the right-angle block 11 can improve the stability of the slider 31.

[0029] Furthermore, several sets of reinforcing ribs 1-8 are fixedly installed on the top of the mounting plate 1, and several sets of reinforcing ribs 2-12 are fixedly installed on the mounting plate 1. The reinforcing ribs 1-8 and 2-12 are set vertically. The added reinforcing ribs ensure the improvement of the load-bearing capacity of the mounting plate 1 at the hoisting point.

[0030] Working principle: First, determine how to hoist the items according to the on-site construction environment. Then, open the shielding component 2 and drive the horizontal moving component 3 by adjusting component 6, so that the four sets of hanging lugs 4 move to the appropriate hoisting positions. Then, connect the two sets of hanging rings 7 to the external hoisting equipment, and then connect the four sets of hanging lugs 4 to the items to be hoisted in sequence. This hoisting device can effectively solve the hoisting of steel components below the foundation pit support in confined spaces.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
