[0013] The beneficial effects of the present invention are as follows: 1. By providing a lifting power system that can both rise (build a building) and fall (demolish a building), the entire system has good versatility and is convenient for application to different usage requirements and work scenarios. At the same time, the entire system has a simple structure and stable operation, and is easy to apply to building construction and demolition machinery and equipment; 2. By adopting a lifting power system that is easy to operate, the whole system can rise (build buildings) and fall (demolish buildings) more smoothly and quickly, thus achieving the effect of convenient operation and improving construction efficiency; 3. The present application achieves this by 1) reasonably designing the shape of the upper crossbeam mounting seat and the shape of the rotating arm; 2) installing a motor on the top plate to drive the rotating shaft to control the rotation of the rotating arm so that it can be extended or retracted from the working hole range, and both ends of the working hole have rotating arm matching parts that turn toward the same side; 3) contact sensor 1 and contact sensor 2 are arranged on the top plate of the upper crossbeam mounting seat, contact slope seat 1, contact slope seat 2 and stop plate 1 are arranged on the rotating arm, and stop plate 2 located between the top plate and the bottom plate, and the rotating arm can be fitted through contact sensor 1 after reaching the position where it extends out of the working hole range. On the contact slope 1 and the blocking bolt 1 is attached to the sensor mounting seat 1, the double blocking and limiting is performed, and the motor can be controlled to stop working by the contact sensor 1. When the swing arm retracts to the working opening, the swing arm rotates to the contact sensor 2 to be attached to the contact slope 2 and the blocking bolt 2 is attached to the sensor mounting seat 2 to double block and limit, and the motor can be controlled to stop working by the contact sensor 1; 4) The blocking bolt 1 and the blocking bolt 2 are respectively fixed by two nuts, and the front and rear positions can be adjusted, which is convenient for adjusting whether the swing arm can be smoothly extended into and retracted into the working opening range. The combination of the above four points can realize that the load-bearing beam on the electric swing arm can be electrically controlled to be loaded on the floor slab, without the need for manual insertion and extraction control in the form of casing and rods in the past, and has good automation and efficient task execution. This not only saves time and resources, but also completes more work in a shorter time, reduces the pressure on workers, and improves work efficiency.

Both ends of the working opening 7 have a rotating arm 901 matching portion that turns toward the same side. A lifting jack 4 is arranged inside the column assembly 2 and is used to control the synchronous lifting and lowering of the column assembly 2 and the top truss system 1; The guide wheel group 5 is arranged on the floor 8 of each layer and is used to contact the four sides of the column assembly 2 to achieve the limit of the column assembly 2 during the lifting process, limit the column assembly 2 to stably slide along the vertical direction, and provide stability during the process; The steel strand 6 is vertically arranged in the column assembly 2 and passes through the interior of the lifting jack 4, and is clamped and fixed by the upper and lower working parts of the lifting jack 4, so that when the telescopic cylinder of the lifting jack 4 works, it can exert an action on the column assembly 2 in a positive or reverse direction, so that the column assembly 2 can be stably raised or lowered; The electric tumbler upper bearing beam 9 is fixed below the lifting jack 4. The electric tumbler upper bearing beam 9 includes a horizontally arranged upper beam mounting seat 902 and tumblers 901 respectively hinged at both ends of the upper beam mounting seat 902.

The top of the driving shaft 906 extends out of the top plate 903 and is connected to a motor 907. A rotating arm is fixedly connected to the driving shaft 906. The rotating arm 901 is used to press against the floor slab to achieve a supporting function.

[0019] The lower bearing crossbeam 10 of the electric tumbler is fixed below the column assembly 2 and has the same structure as the upper bearing crossbeam.

[0020] In a preferred example, the present invention can be further configured as follows: a sensor mounting seat 908 is fixed at the end of the top plate 903, and a contact sensor 909 extending above the rotating arm 901 is fixed on the sensor mounting seat 908; a sensor mounting seat 910 is fixed on the side end of the top plate 903, and a contact sensor 911 extending above the rotating arm 901 is fixed on the sensor mounting seat 910; a contact slope seat 912, a contact slope seat 913 and a stop plate 914 located between the contact sensor 909 and the contact sensor 911 are fixed on the top of the rotating arm 901; a contact slope seat 912 is provided with a contact slope 915 at one end close to the contact sensor 909, a contact slope seat 913 is provided with a contact slope 916 at one end close to the contact sensor 911, and a stop plate 914 is provided horizontally on its upper edge. A blocking bolt 917 passes through the blocking seat plate, and the blocking bolt 917 is threadedly connected to the fixing nuts 918 located on both sides of the blocking seat. When the swing arm 901 rotates to the length direction of the upper beam mounting seat 902, the contact sensor 909 is attached to the contact slope 915 and the blocking bolt 917 is attached to the sensor mounting seat 908, and the swing arm 901 extends out of the range of the working hole 7; a blocking seat plate 919 is arranged between the top plate 903 and the bottom plate 904, and the blocking seat plate 919 is located on one side of the contact sensor 911.

When the swing arm 901 rotates until the contact sensor 911 is attached to the contact slope 916 and the blocking bolt 920 is attached to the sensor mounting seat 910, the swing arm 901 is located in the working hole 7; In a preferred example, the present invention can be further configured as follows: the column assembly 2 includes left and right columns 201, an upper fixed connecting beam 202, a lower fixed connecting beam 203 and a load-bearing connecting beam 204, the left and right columns 201 are vertically and arranged side by side, the upper fixed connecting beam 202 and the lower fixed connecting beam 203 are distributed up and down between the left and right columns 201, and are used to fix the two ends of the steel strand 6, the load-bearing connecting beam 204 is arranged below the lower fixed connecting beam 203, and is used to install and fix the lower load-bearing beam 10 of the electric jib, so as to increase the supporting stability of the structural strength of the lower load-bearing beam 10, and ensure the stability of the entire lifting system during operation.

[0021] In a preferred example, the present invention can be further configured as follows: an electric hoist 3 is provided in the column assembly 2, the electric hoist 3 is located above the lifting jack 4, and the hook of the electric hoist 3 can reach the upper side wall of the lifting jack 4 for lifting.

[0022] Therefore, when the entire lifting jack 4 needs to be raised or lowered by a distance of one floor, the electric hoist 3 is used to quickly move the lifting jack 4 along the steel strand 6, making the construction process more convenient and improving the construction efficiency.

[0023] In a preferred example, the present invention can be further configured as follows: the guide wheel group 5 includes a mounting frame 501 and a roller 502, the mounting frame 501 is used to be fixed on the floor 8, and the roller 502 is rotatably connected to the front end of the mounting frame 501 and is used to resist the outer wall of the column assembly 2.

[0024] Therefore, when lifting operations are required, the guide wheel group 5 at the very end can be disassembled, and then the disassembled guide wheel group 5 can be installed. During installation, it is only necessary to fix the mounting frame 501 with bolts or anchor rods to achieve quick fixation of the guide wheel group 5, making the construction operation process easier and more convenient.

[0025] Embodiment 2 In a preferred example, the present invention can be further configured as follows: the mounting frame 501 includes a base 51, a slide 52, a suspension 53, a screw 54 and a handle 55; the base 51 is used to be fixed on the floor 8; the slide 52 is horizontally slidably connected to the base 51; the suspension 53 is arranged on the slide 52 and is used for the roller 502 to be installed and fixed; the screw 54 is horizontally threadedly connected to the rear of the base 51 and is rotatably connected to the rear end of the slide 52; and the handle 55 is arranged at the rear end of the screw 54.

[0026] In a preferred example, the present invention can be further configured as follows: the suspension 53 is rotatably connected to the slide 52, a circular arc-shaped guide rod 56 is provided on the slide 52, a guide tube 57 slidably connected to the guide rod 56 is provided at the tail end of the suspension 53, and a screw 58 for pressing the upper end surface of the guide rod 56 is vertically threadedly connected to the guide tube 57.

[0027] When the guide wheel group 5 needs to be fixed, the base 51 can be fixed on the ground at will, and then the suspension 53 is controlled to rotate so that the suspension 53 and the roller 502 face forward, and then the handle 55 is controlled to drive the screw 54 to rotate so that the slide 52 slides forward horizontally. At this time, the slide 52 drives the suspension 53 and the roller 502 to move synchronously.

[0028] And until the roller 502 hits the outer wall of the column assembly 2, the suspension 53 and the roller 502 are controlled to rotate synchronously, so that the roller 502 can be pressed against the outer wall of the column assembly 2, and then the screw 58 is tightened to achieve the installation and fixation of the guide wheel assembly 5.

[0029] Therefore, by setting the guide wheel group 5 with adjustable front and rear positions and rotation angles, the guide wheel group 5 can be fixed at will, and the operating requirements of the guide wheel group 5 can be met through fine-tuning. There is no need for workers to lay out lines before installation, nor is there a need for precise installation, which makes the installation process of the guide wheel group 5 more convenient and improves construction efficiency.
