DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 A stable engineering construction frame comprises a base 1, two groups of support columns 3 welded on both sides of the top wall of the base 1, and a bearing plate 4 welded on the two groups of support columns 3, pulleys 2 are installed at the four corners of the bottom wall of the base 1, and each group of support columns 3 is arranged with multiple equal intervals in the horizontal direction, and a guardrail 5 is welded on the outer circle of the top wall of the bearing plate 4, wherein the guardrail 5 plays a role in protecting the personnel standing on the bearing plate 4 and the objects placed on the bearing plate 4;

[0022] Infrared distance sensors 6 are installed on the four side walls of the carrying plate 4, and the probes of the four infrared distance sensors 6 are arranged vertically downward. A display screen 7, an audible and visual alarm 8 and a controller 9 are also installed on the base 1, wherein the display screen 7, the audible and visual alarm 8 and the four infrared distance sensors 6 are all electrically connected to the controller 9. The infrared distance sensor 6 can refer to the technical principle of the HL-LD01-4M model in the prior art, and the controller 9 can refer to the technical principle of the S7-200 model in the prior art;

[0023] Casings 10 are welded at the four corners of the top wall of the base 1, and hand wheels 11 are rotatably connected to the four casings 10. Slide grooves 12 are formed in the bottom wall of the base 1 toward the four casings 10, and screw rods 13 are coaxially connected below the four hand wheels 11. The four screw rods 13 are respectively vertically arranged in the four slide grooves 12, and the four screw rods 13 are respectively rotatably connected to the four casings 10, so that the four screw rods 13 can operate stably, and the four screw rods 13 are respectively threadedly sleeved with movable legs 14, and the four movable legs 14 are respectively fitted with the inner walls of the four slide grooves 12;

[0024] It is worth noting that a cylinder 15 is horizontally installed on each of the four movable legs 14, and a storage groove 16 is formed on the side walls of the four movable legs 14. Positioning blocks 17 are respectively connected to the four cylinders 15. The four positioning blocks 17 are respectively located in the four storage grooves 16. The positioning blocks 17 fit with the inner walls of the storage grooves 16 so that the positioning blocks 17 can only move horizontally but not shake. A group of sockets 18 are formed in the four slide grooves 12 toward the base 1, and each group of sockets 18 is arranged with multiple equal intervals in the vertical direction. The positioning block 17 is inserted into one of the sockets 18, so that the positioning block 17 is used to keep the structure of the movable leg 14 stable and motionless, thereby ensuring the stability of the base 1.

[0025] The stable engineering construction frame: when in use, firstly detect the distance between the four infrared distance sensors 6 and the ground, and transmit the electric signal to the controller 9, so that the controller 9 transmits the electric signal to the display screen 7, thereby displaying the values ​​of the four groups of distances in real time. When the values ​​of the four groups of distances are greater than the error range (the value of the error can be set according to the actual situation, if it is 3%, then the difference between the maximum value and the minimum value of the four groups of data shall not exceed 3%), the controller 9 transmits the electric signal to the sound and light alarm 8, so that it is powered on and reminds the personnel to adjust the position of the base 1. When the two ends of the base 1 are in planes at different angles, the distance values ​​detected by the four groups of infrared distance sensors 6 will have a large difference, so the sound and light alarm 8 will work to remind the personnel to adjust, thereby ensuring the safety of the personnel and objects on the bearing plate 4; after the base 1 is level, the four hand wheels 11 are rotated respectively to drive the four screw rods 13 to operate, so that the four movable legs 14 gradually sink and contact the ground, so that the four pulleys 2 are separated from the ground, and the stability of the base 1 and the bearing plate 4 can be ensured.
