[0021] Please see Figure 1 - Figure 4 This utility model provides a lifting frame for building reinforcement construction, including a base plate 1 and a top plate 2. The base plate 1 and the top plate 2 are connected by two sets of scissor-type lifting brackets 7. The two sets of scissor-type lifting brackets 7 are rotatably connected by multiple support rods 6. Hydraulic cylinders 3 are respectively provided on both sides of the base plate 1. The hydraulic cylinders 3 are fixedly connected to the first slider 5 through hydraulic rods 4. The first slider 5 is set in the limiting groove 16. A connecting rod 6 is fixedly connected to the first slider 5. The arrangement direction of the connecting rod 6 is perpendicular to the hydraulic rod 4. The lower side of the top plate 2 is provided with a parallel limiting groove for limiting the upper end point of the telescopic lifting bracket 7.

[0022] Fixing devices 9 are installed at the four corners of the base plate 1 to fix the lifting frame to the ground. A control device 8 is also installed on the base plate 1. Baffles 10 are installed around the top plate 2. Tool slot 11 and tool slot 12 are installed inside the baffles 10. A sliding groove 15 is installed at the top of the baffles 10. A limiting device 13 is installed in the sliding groove 15. The limiting device 13 can move within the sliding groove 15 and is used to fix the safety belt.

[0023] This utility model provides a technical solution: the support device 9 includes a first spiral rod 902, with a spiral handle 901 fixedly connected to the top end of the first spiral rod 902 and a support plate 903 fixedly connected to the bottom end. A ground plug 904 is fixedly connected to the center of the bottom end of the support plate 903. Through the above technical solution, after the utility model is moved to the designated position, the spiral handles 901 at the top of the four support devices 9 are turned in sequence, causing the first spiral rod 902 to rotate downward and drive the support plate 903 and the ground plug 904. After the ground plug 904 is inserted into the ground, the support plate 903 supports the ground and provides support for the utility model. The threaded transmission design of the spiral rod 902 allows the height of the support plate 903 to be manually adjusted according to the flatness or hardness of the ground, ensuring that the equipment can still be stably erected on complex terrain.

[0024] This utility model provides a technical solution: the ground insert 904 is a spiral ground insert. Through the above technical solution, the ground insert 904 can be inserted into the ground more easily and has a larger contact area with the soil, resulting in better stability.

[0025] This utility model provides a technical solution: the limiting device 13 includes a second spiral rod 1302 and a second slider 1303. The second spiral rod 1302 is rotatably connected to the second slider 1303 through a threaded hole passing through the second slider 1303. A pull ring 1301 is fixedly connected to the top end of the second spiral rod 1302; a limiting block 1304 is fixedly connected to the bottom end. With the above technical solution, after the worker determines the working direction and position, he adjusts the limiting device 13 to slide in the slide groove 15. After adjusting the position of the limiting device 13, he twists the pull ring 1301 to drive the second spiral rod 1302 and the second slider 1303 to move downward. After the second slider 1303 contacts the bottom of the slide groove 15, it fixes the entire limiting device 13. Then, the safety belt buckle is hooked onto the pull ring 1301 to ensure the safety of the worker, prevent falls, and facilitate operation.

[0026] This utility model provides a technical solution: the first tool slot 11 is L-shaped and is fixedly connected to the inner side of the long plate of the baffle 10. Through the above technical solution, the tool slot is set to facilitate workers to take out tools, which solves the problem of low work efficiency caused by repeatedly going to the ground to take out tools.

[0027] This utility model provides a technical solution: the second tool slot 12 is an inclined plate with an angle greater than 90 degrees to the top plate 2, and is fixedly connected to the top plate 2. Through the above technical solution, the tool slot is increased to store more tools, and at the same time, the setting of the inclined plate does not reduce the activity area of ​​the worker's feet.

[0028] Working principle: After the utility model is moved to the working position via the casters 14, the screw handles 901 on the top of the four support devices 9 are turned in sequence, causing the first screw rod 902 to rotate and move downwards, driving the support plate 903 and the ground plug 904. After the ground plug 904 is inserted into the ground, the support plate 903 supports the ground, providing support for the utility model. If the ground is uneven, the corresponding support device 9 is adjusted according to the slope to achieve balance. Then, the workers use a ladder to reach the top plate 2, put the required tools into the first tool slot 11 and the second tool slot 12, and then hang the safety belt buckle on the pull ring 1301. Then, the workers on the ground use the control device 8 to control the hydraulic cylinder 3 to start. Hydraulic cylinder 3 drives hydraulic rod 4 to push slider 5 to slide within limit groove 16. Slider 5 drives connecting rod 6 to move synchronously. Connecting rod 6 drives two sets of scissor lift brackets 7 to lift upwards. Top plate 2 at the top of scissor lift bracket 7 lifts upwards synchronously. After reaching the working height, the lifting stops. At this time, after the workers at the height determine the working direction and position, they adjust the limit device 13 to slide within slide groove 15. After adjusting the position of limit device 13, they turn pull ring 1301 to drive screw rod 1302 and slider 1303 downwards. After slider 1303 contacts the bottom of slide groove 15, it fixes the entire limit device 13, and the workers can start working.
