[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Please refer to Figure 1 Traditional building lifting devices are prone to violent movement when the motor fails, which cannot guarantee the safety of the operators. Even when fully retracted, they still occupy a large area, which has a great impact on transportation and placement.
[0019] Based on the above problems, the utility model adopts a herringbone design so that the area when fully retracted is smaller than that of a traditional lifting device, and the motion mechanism adopts left and right spiral screws. Even if the motor fails, the screw slider will not move. For specific details, refer to the following embodiments.
[0020] See also Figure 1-3, a lifting device for building, characterized in that: it includes a base 5, slide grooves 1 are opened on both sides of the top of the base 5, and a limit block 101 is fixedly installed inside the slide groove 1. The side of the limit block 101 is rotatably connected with a left and right spiral screw 103, and the other end of the left and right spiral screw 103 is provided with a rotating motor 104, and the left and right spiral screws 103 are provided with two screw sliders 102. Two groups of symmetrical lifting plates 2 are rotatably connected to the screw sliders 102, and the other end of the lifting plate 2 is rotatably connected to the two sides of the flat plate 3. The two lifting plates 2 are in a herringbone shape, and a telescopic plate 4 is fixedly connected above the flat plate 3.
[0021] The left and right spiral screws 103 on the slide slot 1 are four small strips, so that the telescopic plate 4 on the top can remain stable when the lifting rod keeps moving.
[0022] The left and right spiral screws 103 include a right-hand screw 6 and a left-hand screw 7 , and a baffle 8 is provided between the right-hand screw 6 and the left-hand screw 7 .
[0023] Among them, each of the right-handed screw 6 and the left-handed screw 7 of the left and right spiral screws 103 is provided with a screw slider 102. When moving, the two screw sliders 102 move to both ends or the middle at the same time to support the two lifting plates 2 so that they can achieve a herringbone opening and closing.
[0024] The telescopic plate 4 is fixed at both ends and telescopic in the middle.
[0025] Working principle: when it is necessary to lower the height of the building lifting device, start the rotating motor 104 to make it rotate forward, and the screw slider 102 on each left and right spiral screw 103 moves toward both ends, driving the lifting plate 2 to rotate toward both ends with the flat plate 3 as the center, so that the bottom spacing of the lifting plate 2 becomes larger, and the telescopic plate 4 is shortened to the middle position. When it is necessary to increase the height of the building lifting device, start the rotating motor 104 to reverse it, and the screw slider 102 on each left and right spiral screw 103 moves toward the middle, driving the lifting plate 2 to rotate toward the middle with the flat plate 3 as the center, so that the bottom spacing of the lifting plate 2 becomes smaller, and the telescopic plate 4 extends to both ends.
[0026] In the description of the present invention, it should be noted that, unless otherwise specified, “plurality” means two or more than two; the orientations or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “inside”, “outside”, “top”, and “bottom” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
