[0023] 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.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a construction platform with stable lifting, including a base plate 1 and a lifting box 2, a limiting groove 3 is provided on one side of the top of the base plate 1, a double-headed motor 4 is fixedly connected inside the limiting groove 3, the output ends of the double-headed motor 4 are fixedly connected with threaded rods 5, the external threads of the threaded rods 5 are connected with moving blocks 6, the external parts of the moving blocks 6 are fixedly connected with connecting rods 8, both ends of the connecting rods 8 are rotatably connected with support rods 10, a plurality of slide grooves 11 are provided at the bottom of the lifting box 2, a slider 12 is slidably connected inside the slide grooves 11, and two leveling components 14 are installed on both sides of the base plate 1.

[0025] The bottom plate 1 plays a supporting role on the whole device, so that the lifting box 2 can be lifted and lowered smoothly, thereby ensuring the safety of construction workers when using it. The double-headed motor 4 drives the threaded rods 5 at both ends to rotate, so that the moving block 6 outside the threaded rod 5 moves along the direction of the limit groove 3. The limit groove 3 limits the moving block 6, so that when the threaded rod 5 rotates, the moving block 6 can only move in the horizontal direction, thereby driving the connecting rod 8 to move. The connecting rod 8 drives the supporting rods 10 connected at both ends to move, so that the other end can slide along the slide groove 11 when it is rotatably connected to the slider 12, so as to change the height of the lifting box 2 and realize the height adjustment of the construction platform. At the same time, the rotating shaft 7 is connected to the middle parts of multiple support rods 10, so that two adjacent support rods 10 are more stable when rotating, ensuring the overall effect of the structure operation, and through the telescopic rods 13 connected on both sides of the lifting box 2, it can be made more stable when lifting, thereby ensuring safety during use.

[0026] Reference Figure 4 The leveling component 14 includes a mounting groove 1401, and the mounting groove 1401 is opened on the side of the base plate 1. One side of the interior of the mounting groove 1401 is rotatably connected to a telescopic rod 1402, and the other side of the telescopic rod 1402 is rotatably connected to a rotating rod 1403, and the other end of the rotating rod 1403 is fixedly connected to a cylinder 1404; the output end of the telescopic rod 1402 is rotatably connected to the inside of the rotating rod 1403, and the output end of the cylinder 1404 is installed with a buffer pad.

[0027] Specifically, by rotatably connecting the telescopic rod 1402 and one end of the rotating rod 1403 inside the installation groove 1401, the leveling assembly 14 can be folded up when not in use, reducing the occupied space and facilitating movement. By starting the telescopic rod 1402, the rotating rod 1403 can be pushed to rotate, and then the cylinder 1404 is started to push the buffer pad connected to the output end, so that the overall placement of the device can be made more stable and can be suitable for uneven ground. The base plate 1 is adjusted to a horizontal state to ensure stability during lifting.

[0028] Reference Figure 1 , Figure 2 and Figure 3, a limiting block 9 is fixedly connected to one side of the top of the base plate 1, and one end of the connecting rod 8 is slidably connected to the inside of the limiting block 9; the longitudinal section of the moving block 6 is set to be square, and the outside of the moving block 6 is slidably connected to the inner wall of the limiting groove 3; the left and right sides of the top of the base plate 1 are fixedly connected with a telescopic rod 13, and the output end of the telescopic rod 13 is fixedly connected to the bottom of the lifting box 2; the middle inside of the support rod 10 is rotatably connected with a rotating shaft 7, and the other end of the support rod 10 is rotatably connected to the bottom of the slider 12 respectively; the four corners of the bottom of the base plate 1 are fixedly connected with universal wheels 15.

[0029] Specifically, by fixing the limit block 9 on the top side of the base plate 1 and placing one end of the connecting rod 8 inside it, the connecting rod 8 will not be offset when sliding, ensuring that the structure is more stable when lifting and lowering. The moving block 6 is placed inside the limit groove 3 and its longitudinal section is set to a square, so that the threaded rod 5 can only move in the horizontal direction when driving it to rotate, thereby achieving the effect of adjusting the height of the lifting box 2. The telescopic rod 13 can make the lifting and lowering of the lifting box 2 smoother, ensuring the safety of use. The rotating shaft 7 can ensure that the angle between the two intersecting support rods 10 will not change when rotating, ensuring stability during movement. The other ends of the support rods 10 are rotatably connected to the bottom of the slider 12 respectively, so as to support the lifting box 2 and perform lifting operations. The four universal wheels 15 can push the entire device to move, making the device easy to use.

[0030] Working principle: When using this device, the lifting platform is pushed to the use position through the universal wheel 15, and then the leveling components 14 installed on both sides of the base plate 1 are activated to adjust the base plate 1 to a horizontal state. Specifically, the rotating rod 1403 is pushed to rotate by extending the telescopic rod 1402, thereby expanding the angle between the rotating rod 1403 and the base plate 1, and then the cylinder 1404 is started to push the buffer pad connected to the output end, so that the pad contacts the ground, and by changing the extension length of each cylinder 1404, the base plate 1 is in a horizontal state, thereby ensuring stability during lifting. At the same time, the device is not easy to tip over during use, ensuring the safety of construction workers. Then start the double-headed motor 4, which in turn drives the two threaded rods 5 to rotate, so that the moving block 6 slides inside the limit groove 3 along the direction of the threaded rod 5, further driving the connecting rod 8 to move, and at the same time the other end of the connecting rod 8 slides inside the limit block 9, thereby driving one end of the support rod 10 to move, and making the end connected to the slider 12 slide inside the slide groove 11, thereby realizing the lifting and lowering operation of the lifting box 2. At the same time, under the support of the telescopic rod 13, the lifting state is more stable, so that the construction personnel can approach the construction position faster, improve the construction efficiency, and ensure the safety of the construction.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
