DETAILED DESCRIPTION

[0017] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0018] like Figure 1 As shown, the light vertical lifting device of the utility model includes a base 1, a support frame upright 2, a support frame cross bar 3, a lifting eye 5, and a lifting device 8.

[0019] The base 1 is used to be placed on a horizontal plane. On the one hand, it is used to support the support frame uprights 2, and on the other hand, it is used to increase the bottom weight to prevent tipping and improve the lifting capacity. The base 1 can be made of a steel plate or a concrete slab as long as it can provide sufficient support. The size, area, and thickness of the base 1 are set according to actual conditions and should meet the corresponding load requirements.

[0020] The support frame uprights 2 are vertically arranged on the base 1, and are used to play a supporting role. The height of the support frame uprights 2 is set according to the spatial height of the application scenario, and this embodiment does not limit it. The support frame uprights 2 can be selected from one of I-beams, H-shaped steels, and rectangular steel pipes. In this embodiment, the support frame uprights 2 are preferably I-beams. When the base 1 uses a steel plate, the support frame uprights 2 can be welded to the steel plate. When the base 1 uses a concrete slab structure, the base 1 can be placed vertically first, and then concrete can be poured in the corresponding mold. After the concrete is solidified, the bottom of the support frame uprights 2 is fixed in the base 1, and the two are fixedly connected together. The fixing method of the support frame uprights 2 and the base 1 can be set according to the actual material selection.

[0021] The support frame cross bar 3 is arranged horizontally, one end of which is connected to the top of the support frame upright 2, and the other end is cantilevered to form a free end. The support frame cross bar 3 is cantilevered, which can facilitate the assembly of components or equipment to be installed under the support frame cross bar 3, and then facilitate vertical lifting. The length of the support frame cross bar 3 is set according to actual needs, and it should be able to meet the strength requirements. The support frame cross bar 3 can be made of one of I-beams, H-shaped steel, and rectangular steel pipes. In this embodiment, the support frame cross bar 3 is preferably an I-beam.

[0022] The lifting lug 5 is provided on the support frame cross bar 3, and specifically, it is fixedly provided at the lower end of the support frame cross bar 3. In this embodiment, the lifting lug 5 is welded to the lower end of the support frame cross bar 3 at the proximal end close to the cantilever end.

[0023] The lifting device 8 is used for vertical lifting, and is hung on the lifting lug 5. The lifting device 8 can be selected from one of the well-known hand chain hoists, electric hoists, winches, and pulley blocks, which can be lifted up and down to lift the lifting device to a desired height. In this embodiment, the lifting device 8 is preferably an electric hoist.

[0024] Furthermore, in order to enhance the structural stability, a diagonal brace 4 is provided between the base 1 and the support frame upright 2. One end of the diagonal brace 4 is fixedly connected to the base 1, and the other end of the diagonal brace 4 is fixedly connected to the support frame upright 2. The diagonal brace 4 can be made of a steel pipe or a steel plate, and can be fixedly connected to the support frame upright 2 and the base 1 by welding. Of course, when the base 1 adopts a concrete slab structure, the diagonal brace 4 can also be pre-buried like the support frame upright 2, and then concrete is poured to fix it with the base 1.

[0025] Furthermore, the position where the base 1 is connected to the support frame upright 2 is located in the middle of the support frame upright 2 .

[0026] Furthermore, the diagonal brace 4 and the support frame cross bar 3 are distributed on both sides of the support frame upright 2, so that the diagonal brace 4 can tie the support frame upright 2 together, thereby improving the supporting strength of the support frame upright 2 and preventing the entire device from tipping over during lifting.

[0027] Furthermore, a triangular stiffening plate 7 is provided between the support frame cross bar 3 and the support frame upright 2. The triangular stiffening plate 7 is made of a steel plate, which is fixedly provided at the corner position of the support frame cross bar 3 and the support frame upright 2, one end of which is connected to the support frame cross bar 3, and the other end is connected to the support frame upright 2. In this embodiment, it is connected by welding. The size of the triangular stiffening plate 7 is not limited, and it can be provided as needed. By providing the triangular stiffening plate 7, the structural stability between the support frame cross bar 3 and the support frame upright 2 can be strengthened.

[0028] Furthermore, stiffening plates are provided at the node positions with greater force in the support frame uprights 2 and support frame crossbars 3, for example:

[0029] In some embodiments, a first stiffening plate 61 is provided in the position where the support frame upright 2 is connected to the diagonal brace 4. The first stiffening plate 61 is extended in the transverse direction, and its two ends are fixedly connected to the support frame upright 2, such as welded together, which can strengthen the strength of the support frame upright 2 at this position to meet the force requirements.

[0030] In some embodiments, a second stiffening plate 62 is provided in the position of the support frame cross bar 3 where the lifting ear 5 is provided. The second stiffening plate 62 is extended in the vertical direction, and its two ends are fixedly connected to the support frame cross bar 3, such as welded together, which can strengthen the strength of the support frame cross bar 3 at this location to meet the force requirements.

[0031] In some embodiments, a third stiffening plate 63 is provided at the position where the support frame cross bar 3 is connected to the support frame upright bar 2. The third stiffening plate 63 is arranged to extend in the transverse direction, and its two ends are fixedly connected to the support frame upright bar 2, such as by welding. The third stiffening plate 63 and the fourth stiffening plate can strengthen the strength of the connection and improve the structural stability.

[0032] Thus, the light vertical lifting device of the utility model is formed, which can be moved to the required site, and then the components or equipment can be conveniently lifted to the specified height for installation. Since the support frame cross bar 3 is in a horizontal cantilevered shape, it can not only reduce the overall height and be suitable for the constructed floors, but also can be conveniently assembled under the support frame cross bar 3 for the components and equipment to be installed, so as to facilitate vertical lifting and lift them vertically to the specified height. In addition, if the component to be installed is too large, it can also be coordinated by multiple light vertical lifting devices. By reasonably arranging the lifting point positions, multiple light vertical lifting devices are arranged around the component, and the lifting of each light vertical lifting device is kept relatively synchronous during lifting, so that the overall lifting of the large component can be achieved. The light vertical lifting device of the utility model has a stable structure, is easy to use, and has strong applicability. It can be applied to different lifting environments and has strong applicability.

[0033] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
