[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a movable cantilever frame for construction, including a metal construction base frame 1, a high-strength inner screw barrel 8, a high-strength outer screw rod 10 and a cantilever frame rod 13. The lower end of the metal construction base frame 1 is equipped with casters 2 with foot brakes, and the upper end of the metal construction base frame 1 is horizontally provided with a cantilever frame mounting seat 4. There are four high-strength inner screw barrels 8, and the front ends of the four high-strength inner screw barrels 8 are all screwed with locking bolts 9 through threads. The upper edges of the four high-strength inner screw barrels 8 are welded with high-strength flanges 6, and four high-strength outer screws 10 are provided. The outer screw rod 10 is screwed into the four high-strength inner screw barrels 8 through threads, and the upper ends of the four high-strength outer screw rods 10 are installed with high-strength bearing seats 12. The outer rings of the four high-strength bearing seats 12 are respectively fixed around the lower end of the cantilever frame rod 13. The lower end of the cantilever frame rod 13 is horizontally installed with a height adjustment seat 16 through a plurality of high-strength connecting rods 15. This design solves the problem that when the original device is adjusted in height, the original basic poles and cantilever poles need to be dismantled and then replaced with new basic poles and cantilever poles for installation, which is time-consuming and labor-intensive and not quick and convenient enough.

[0019] As the first embodiment of the utility model: a cement counterweight seat 3 is arranged at the lower end of the metal construction base frame 1, and the added cement counterweight seat 3 can enhance the stability of the metal construction base frame 1. A metal up-and-down ladder 5 is longitudinally installed on the left side of the lower end of the cantilever frame mounting seat 4, and the added metal up-and-down ladder 5 makes it convenient for construction workers to get on and off the device.

[0020] Four high-strength flanges 6 are fixed around the upper end of the cantilever frame mounting seat 4 by multiple hexagonal fastening bolts 7, and four high-strength inner screw barrels 8 pass through the lower end of the cantilever frame mounting seat 4 respectively. The four high-strength flanges 6 and multiple hexagonal fastening bolts 7 are added to facilitate the four high-strength inner screw barrels 8 to be fixed around the lower end of the cantilever frame mounting seat 4. The upper ends of the annular sides of the four high-strength outer screws 10 are fixed with fixed screw rings 11. The added fixed screw rings 11 facilitate the construction personnel to rotate the four high-strength outer screws 10 in the same direction. The front and rear sides of the upper end of the cantilever frame rod 13 are both installed with railings 14. The added railings 14 can enhance the safety of the construction personnel in the cantilever frame rod 13.

[0021] As the second embodiment of the present utility model: when construction workers need to use the device, they push the metal construction base frame 1, the device can be moved to the construction site, loosen the four locking bolts 9, and then let two construction workers simultaneously turn the four fixed screw rings 11 in the same direction and at the same speed, and the four high-strength external screws 10 can rotate and move upward in the four high-strength internal screw barrels 8. In this process, the inner rings of the four high-strength bearing seats 12 can be driven to rotate and move upward, and force the outer rings of the four high-strength bearing seats 12 to drive the cantilever frame rod 13 to move upward, and the upward movement of the cantilever frame rod 13 will drive multiple high-strength connecting rods 15 to move upward, and then drive the height adjustment seat 16 to move upward, and finally tighten the four locking bolts 9 so that the threaded ends of the four locking bolts 9 are tightly against the front ends of the four high-strength external screws 10, so that it is convenient for construction workers to stand on the height-adjusting seat 16 to perform construction operations according to the actual needs of the construction.
