[0028] This utility model proposes a lifting support device and a lifting light projection device, aiming to solve the problem of insufficient wind resistance of existing devices.

[0029] Example 1

[0030] See Figures 1 to 3 A lifting support device is installed on a foundation pit 1 in the ground. It includes a fixed base 2, a lifting body 3, a reinforcing beam 4, and a mounting frame 5. The fixed base 2 is connected to the bottom wall of the foundation pit 1. The lifting body 3 is vertically mounted on the fixed base 2. The lifting body 3 is connected to the two side walls of the foundation pit 1 via the reinforcing beam 4. The mounting frame 5 is connected to the lifting body 3, and the lifting body 3 can drive the mounting frame 5 to rise and fall vertically. In actual operation, the mounting frame 5 can rise and fall vertically under the action of the lifting body 3. Furthermore, the lifting body 3 is connected to the inner wall of the foundation pit 1 via the fixed base 2 and the reinforcing beam 4, thereby increasing the connection strength between the lifting body 3 and the foundation pit 1 and effectively improving the wind resistance performance of the lifting support device for outdoor use.

[0031] In another example of this embodiment, the lifting body 3 includes a lifting rod 3.1 and an electric push rod 3.2. The lifting rod 3.1 includes two or more lifting sleeves 3.1.1 arranged sequentially in the vertical direction, with the upper lifting sleeve 3.1.1 slidably fitted inside the lower lifting sleeve 3.1.1. The lower lifting sleeve 3.1.1 is connected to the fixed base 2, and the upper lifting sleeve 3.1.1 is connected to the mounting frame 5. The electric push rod 3.2 is connected between the lower lifting sleeve 3.1.1 and the upper lifting sleeve 3.1.1, and can drive the lifting rod 3.1 to extend or shorten in the vertical direction. The electric push rod 3.2 drives the telescopic components to slide relative to each other through the upper lifting sleeve 3.1.1 to perform lifting and lowering, thereby flexibly adjusting the height of the mounting frame 5 to adapt to different height support requirements.

[0032] In this embodiment, the interface of the lifting sleeve 3.1.1 is square. The square lifting sleeve 3.1.1 has a radial limiting function, which can prevent the mounting bracket 5 from being radially offset by external forces.

[0033] In this embodiment, the electric push rod 3.2 includes a drive motor, a screw, and telescopic cylinders. The number of telescopic cylinders is the same as the number of lifting sleeves 3.1.1 and they are arranged in a one-to-one correspondence. The drive motor is mounted on the bottom lifting sleeve 3.1.1. The screw is vertically arranged and connected to the output shaft of the drive motor. The telescopic cylinders are arranged sequentially in the vertical direction, with the upper telescopic cylinder slidingly fitted inside the lower telescopic cylinder. Except for the bottom telescopic cylinder, the other telescopic cylinders are threadedly connected to the screw through nut seats. The other telescopic cylinders are also connected to the corresponding lifting sleeves 3.1.1 through connecting parts. The drive motor drives the screw to rotate so that each telescopic cylinder can slide through each nut seat, thereby causing the corresponding lifting sleeve 3.1.1 to slide up and down. In this embodiment, the electric push rod 3.2 has been disclosed in existing patents and will not be described in detail here. Any matters not covered are common knowledge.

[0034] Specifically, the lifting rod 3.1 also includes a limiting structure. The lifting sleeve 3.1.1 is equipped with a limiting structure that can limit the movement of the previous lifting sleeve 3.1.1 sliding within it. The two lifting sleeves 3.1.1 are limited by the limiting structure to prevent them from disengaging and ensure operational stability. In this embodiment, the limiting structure is a stop block located within the lifting sleeve 3.1.1. When the bottom end of the previous lifting sleeve 3.1.1 slides to the stop block within the next lifting sleeve 3.1.1, the stop block can limit its movement.

[0035] Furthermore, there are two electric actuators 3.2, symmetrically arranged on both sides of the lifting rod 3.1. The two electric actuators 3.2 work together to improve the stability of the lifting operation and increase the support strength of the lifting body 3, which is beneficial to enhancing wind resistance.

[0036] Furthermore, the lifting sleeve 3.1.1 is provided with a grid-shaped perforated section A. The grid-shaped perforated section A can reduce the weight of the lifting sleeve 3.1.1 and allow air to pass through, further enhancing the wind resistance of the lifting support device when used outdoors.

[0037] In this embodiment, the lifting rod 3.1 further includes a guide wheel assembly 3.1.2, and each lifting sleeve 3.1.1 is slidably connected to the others via the guide wheel assembly 3.1.2. The upper lifting sleeve 3.1.1 is slidably disposed within the lower lifting sleeve 3.1.1 via the guide wheel assembly 3.1.2 to improve the smoothness of sliding.

[0038] In addition, the lifting support device also includes anchors 6 and anchor bolts 7. The two ends of the reinforcing beam 4 are connected to the side wall of the pit 1 through anchors 6; the fixed base 2 is connected to the bottom wall of the pit 1 through anchor bolts 7. Anchors 6 and anchor bolts 7 can effectively enhance the connection strength between the reinforcing beam 4 and the fixed base 2 and the inner wall of the pit 1, ensuring the stability of the overall structure.

[0039] In this embodiment, the lifting support device further includes a protective plate 8 and a sealing element. The protective plate 8 is disposed at the opening of the pit 1, and the protective plate 8 has a through hole for the lifting body 3 to pass through. The sealing element is disposed in the through hole to seal the gap between the through hole and the lifting body 3. The protective plate 8 and the sealing element can effectively prevent external debris or rainwater from entering the pit 1 and corroding the structure inside the pit 1. In this embodiment, there are two through holes, which are respectively provided corresponding to the lifting sleeve 3.1.1 and the electric push rod 3.2 at the bottom end.

[0040] Example 2

[0041] The difference from Embodiment 1 is that the lifting body 3 is a telescopic hydraulic cylinder. The telescopic hydraulic cylinder is equipped with a hydraulic system that provides power to the telescopic hydraulic cylinder.

[0042] Example 3

[0043] This embodiment provides a lifting light projection device, including a light source 9, a projector, and the lifting support device described above. Both the light source 9 and the projector are mounted on a mounting frame 5. There are multiple light sources 9, which are arranged in an array on the mounting frame 5.

[0044] Since the lifting light projection device includes the lifting support device as described above, the lifting light projection device has all the beneficial effects of the lifting support device, which will not be elaborated here.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
