[0002] Aircraft ground stations utilize communication technology to receive real-time data on the aircraft's position and status, and send commands to control its flight. The ground station is equipped with multiple standard cabinets, and chassis are installed within these cabinets. Due to limited space within the cabinets, only one person can work inside at a time during chassis installation. Furthermore, the chassis are relatively heavy (80kg and 120kg respectively) and have an installation height of approximately 1.6m. Relying solely on manual labor for chassis installation is not only physically demanding but also poses safety risks such as injury from impacts or crushing. To address this issue, an innovative chassis installation facility suitable for confined spaces is essential. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] See Figure 1. Figure 2 , Figure 3This utility model provides a chassis lifting bracket suitable for narrow spaces. It includes a base frame 1, a lifting body 2, a lifting drive component 3, and an electrical control box 4. The base frame 1 includes a base plate 1-1, support columns 1-2, and a support plate 1-3. The base plate 1-1 is a square aluminum plate placed on a horizontal ground. The lifting drive component 3 is fixedly installed in the middle of the base plate 1-1. The electrical control box 4 and a set of support columns 1-2 are also installed on the base plate 1-1. The support columns 1-2 are arranged at the four corners of the base plate 1-1 and have a hollow cylindrical structure. The top of the support columns 1-2 is fixedly connected to the support plate 1-3. The support plate 1-3 has a through hole for the lifting arm of the lifting drive component 3 at its center. The lifting drive component 3 is an electric servo cylinder. A flange 3-1 is connected to the top of the lifting arm of the electric servo cylinder. The flange 3-1 is fitted with the lifting body 2. The electrical control box 4 contains a power module, an electric servo cylinder controller, and operation buttons.
[0030] See Figure 1 , Figure 2 , Figure 4 , Figure 5 The chassis lifting bracket suitable for narrow space arrangement according to the present invention includes a lifting body 2 comprising a lower plate 2-2, an upper plate 2-3, a horizontal roller conveyor 2-5, and a universal ball assembly 2-8. The lower plate 2-2 is fixedly connected to the lifting arm of the lifting drive component 3 through a flange 3-1. Several universal ball assemblies 2-8 are installed on the lower plate 2-2. The upper plate 2-3 is mounted on the universal ball assembly 2-8. The upper plate 2-3 can rotate horizontally relative to the lower plate 2-2 through the universal ball assembly 2-8 to adjust the placement posture of the chassis 5. Spring pins 2-9 are installed between the lower plate 2-2 and the upper plate 2-3. There are at least two sets of spring pins 2-9 arranged at a certain distance. At least two parallel horizontal roller conveyors 2-5 are installed on the upper plate 2-3. Baffles 2-4 are provided on the left and right sides of the upper plate 2-3.
[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The chassis lifting bracket suitable for narrow spaces described in this utility model further includes an upper plate rotation limiting assembly for its lifting body 2. The upper plate rotation limiting assembly consists of a limiting shaft 2-6, a limiting hole 2-3-1, and a set of tension springs 2-7. The limiting hole 2-3-1 is located at the center of the upper plate 2-3. The bottom of the limiting shaft 2-6 is fixedly installed at the center of the lower plate 2-2, and its upper end protrudes through the limiting hole 2-3-1. Its protrusion height is less than the height of the horizontal roller conveyor 2-5, and the diameter of the limiting hole 2-3-1 is larger than the outer diameter of the limiting shaft. This allows the upper plate 2-3 to achieve a small range of horizontal adjustment while rotating. Four tension springs 2-7 are evenly arranged around the limiting shaft 2-6. One end of each tension spring 2-7 is connected to the limiting shaft 2-6, and the other end is connected to the bottom surface of the upper plate 2-3.
[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The chassis lifting bracket suitable for narrow space arrangement described in this utility model is further provided with a lifting guide mechanism, which consists of a set of guide rods 2-1 and linear bearings 1-4; the linear bearings 1-4 are installed on the support plate 1-3 of the base frame 1 and are arranged opposite to the support column 1-2 of the base frame 1; the upper end of the guide rods 2-1 is fixedly assembled with the lower plate 2-2 of the lifting body 2, and the lower end passes through the linear bearings 1-4 and is inserted into the center hole of the support column 1-2 of the base frame 1.
[0033] See Figure 6 , Figure 7 , Figure 8 When using this invention to place the chassis 5 into the rack at the set position, the chassis 5 is first placed on the upper plate 2-3 of the lifting body 2; then, the lifting body 2 is lifted to the set height by an electric servo cylinder; the placement posture of the chassis 5 is adjusted by the horizontal rotation of the upper plate 2-3 relative to the lower plate 2-2 in the lifting body 2. During this process, because the diameter of the limiting hole 2-3-1 is larger than the outer diameter of the limiting shaft, the upper plate 2-3 can achieve a small range of horizontal adjustment (including lateral and longitudinal adjustment) while rotating. When the upper plate rotation limit assembly is in place, the four tension springs 2-7 are stretched. Under the elastic force of the tension springs 2-7, the upper plate 2-3 moves slowly and slightly to precisely adjust the placement of the chassis 5. After the adjustment is in place, the upper plate 2-3 and the lower plate 2-2 are fixedly connected by the spring pins 2-9. Then, the chassis 5 is pushed into the set position of the cabinet by the horizontal roller conveyor 2-5 arranged on the upper plate 2-3. The electric servo cylinder is activated to reset the lifting body 2 to the initial state, thus completing the installation of the chassis 5.
