[0020] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified. Example

[0021] like Figure 1-3 As shown, the utility model provides a regular object hoist that opens and closes automatically by gravity, comprising a fixed frame 1, and a movable frame 2 is connected to the fixed frame 1 for sliding and lifting;

[0022] The fixed frame 1 and the movable frame 2 are slidably connected together to have two clamping jaws 4 in an eight-shaped shape, and when the movable frame 2 moves downward, the two clamping jaws 4 can be driven to open, and when it moves upward, the two clamping jaws 4 can be driven to close;

[0023] The fixed frame 1 is provided with two fixed blocks 9 and a movable block 10 which are arranged in an isosceles trapezoidal shape and are mirror-imaged up and down. The fixed block 9 is fixed in position, and the movable block 10 can be lifted and slid relative to the fixed block 9.

[0024] The movable frame 2 is hinged with two relatively mirror-set hooks 11, and the ends of the two hooks 11 are provided with inclined surfaces. The two hooks 11 can be hooked with the fixed block 9 after the fixed block 9 is separated from the movable block 10, and at this time, the two clamping jaws 4 remain in an open state.

[0025] In this embodiment, specifically, support plates 5 parallel to each other are fixed on two sides of the movable frame 2, and the two support plates 5 are each provided with two slide grooves 6 forming an inverted eight-shaped shape.

[0026] In this embodiment, specifically, two sides of the fixed frame 1 are respectively provided with rails 12 parallel to each other, and the rails 12 are located below the support plate 5 .

[0027] In this embodiment, specifically, the two clamping jaws 4 are both rotatably connected with two sets of pulleys 13 on the inner surface, and are slidably connected with the track 12 through the pulleys 13 on the inner surface. The two clamping jaws 4 are both fixed with positioning pins 7 on the top, and are slidably connected with the slide groove 6 of the support plate 5 through the positioning pins 7. When the movable frame 2 moves downward, the two sets of pulleys 13 of each clamping jaw 4 slide toward the outer end of the track 12, and the positioning pin 7 of each clamping jaw 4 slides toward the top of the slide groove 6.

[0028] Among them, see Figure 2 It can be seen that each side of each clamping jaw 4 is rotatably connected to a group of two pulleys 13 through an axle, and each clamping jaw 4 is penetrated and fixed with a positioning pin 7, which extends out of the sliding groove 6 of the clamping jaw 4 and the two support plates 5 and is slidably connected. When the movable frame 2 drives the support plate 5 to move downward, the positioning pin 7 will slide up in the sliding groove 6, and the pulley 13 will slide like the outer end of the track 12, thereby opening the two clamping jaws 4. It should be noted that the closed state of the two clamping jaws 4 is not that the two clamping jaws 4 are in contact with each other. The closed state is as follows: Figure 2 shown.

[0029] In this embodiment, specifically, a columnar block base 8 is fixed at the center of the fixed frame 1, the fixed block 9 is fixed to the top of the block base 8, and the movable block 10 penetrates the block base 8 and is slidably connected.

[0030] In this embodiment, specifically, a hanging hole 15 is opened on the top of the movable frame 2, and a horizontal limit plate 3 is fixed on the bottom of the fixed frame 1, and the limit plate 3 is located between the two clamping claws 4;

[0031] The limiting plate 3 is used to limit the steel bundle 14 clamped below, and abuts against the top of the steel bundle 14 through a plate-like object to prevent the steel from scattering. Figure 1 The steel bundle 14 shown in the figure can be replaced by steel bars such as steel bars with a length of 12 meters and a diameter of 10 mm. Regular and regular objects can be clamped, hoisted and moved by the practical lifting device of this invention.

[0032] Working principle: When in use, hook the lifting hook of the lifting equipment with the lifting hole 15 of the movable frame 2, drive the movable frame 2 to move downward, and the movable frame 2 drives the two support plates 5 to move downward. Since the two clamping claws 4 slide with the inverted eight-shaped slide grooves 6 of the two support plates 5 through the positioning pins 7, the downward movement of the two support plates 5 will force the two clamping claws 4 to separate, and at the same time, the pulley 13 of the clamping claw 4 will slide on the track 12 of the fixed frame 1. When the movable frame 2 moves downward, it will also drive the two hooks 11 to move downward. Since the end of the hook 11 has an inclined surface, and the outer side of the fixed block 9 has an inclined surface, the two hooks 11 will be forced to open after moving downward and abutting against the inclined surface of the fixed block 9, until the end of the hook 11 drops below the fixed block 9. When the two hooks 11 lose the abutment, they can recover and hook the fixed block 9. At this time, the hooks 11 cannot move up, and the movable frame 2 and the support plate 5 cannot move up either, so that the two clamping jaws 4 are kept in an open state. At this time, the two clamping jaws 4 wrap the steel bundle 14, and then continue to move down the movable frame 2. Due to the inclined surface at the end of the hook 11, it will slide to the bottom of the movable block 10. At this time, the movable frame 2 is moved up again to drive the hook 11 to move up. When the hook 11 moves up, it will drive the movable block 10 to move up until the movable block 10 and the fixed block 9 are fitted to form a regular hexagon. At this time, the hook 11 can be separated from the movable block 10 and the fixed block 9, and the two clamping jaws 4 remain in a closed state due to gravity, firmly clamping the steel bundle 14 to achieve fully automatic opening and closing.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
