DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 5The utility model provides a technical solution: a movable folding steel frame for construction engineering, comprising a movable base 1, two scissor-type telescopic frames 2 are arranged on the top of the movable base 1, a plurality of support plates 3 are rotatably connected between the two scissor-type telescopic frames 2, two slide grooves 4 are provided inside the movable base 1, sliders 5 are slidably connected inside the two slide grooves 4, the two sliders 5 are rotatably connected to the two ends of the two scissor-type telescopic frames 2, and cylinders 6 are fixedly installed inside the two slide grooves 4. The output end of the cylinder 6 is fixedly connected to the slider 5. The two scissor-type telescopic frames 2 are supported by the slider 5, so that the cylinder 6 pushes the slider 5 to move while driving the scissor-type telescopic frames 2. The retractable frame 2 is extended, and the multiple support plates 3 are lifted and lowered accordingly, which is convenient for adjusting the height and spacing of the multiple support plates 3 and facilitating climbing. The multiple support plates 3 all include a main body 31, and the corresponding two sides of the main body 31 are rotatably connected with side plates 32. The top of the mobile base 1 and the corresponding two sides of the slide groove 4 are threadedly connected with two limit frames 7, and the four limit frames 7 respectively pass through the two ends of the multiple support plates 3. The inner part of the side plate 32 is provided with a limit hole 8 that matches the limit frame 7, so that the multiple limit frames 7 limit the multiple support plates 3 to ensure their flatness and stability during lifting and lowering to avoid tilting. The limit frame 7 includes a plurality of frame bodies 71, and the plurality of frame bodies 71 are threadedly connected The bottom of the plurality of frames 71 are all installed with threaded columns 9, and the tops of the plurality of frames 71 and the top of the mobile base 1 are all provided with threaded grooves 10 matched with the threaded columns 9. The threaded connection structure facilitates the installation and disassembly of the frames 71 and the adjustment of the length of the limit frame 7. The surface of the support plate 3 is provided with an anti-skid layer to increase the friction with the sole, which is beneficial to prevent the foot from slipping. The inside of the side plate 32 is provided with a positioning hole 33, and the corresponding two sides of the main body 31 are provided with positioning grooves 34. The inside of the positioning groove 34 is slidably connected with a plug 35, and one end of the plug 35 is inserted into the positioning hole 33. The inside of the positioning groove 34 is provided with a telescopic spring 36. The spring 36 is connected to the other end of the plug 35, and a trigger block 37 is installed on one side of the plug 35. With the deformation of the telescopic spring 36, the trigger block 37 can pull the plug 35 to move and withdraw it from the positioning hole 33 of the side plate 32, thereby releasing the limit on the side plate 32, allowing the side plate 32 to be flipped over to reduce the space occupied. Similarly, the side plate 32 can also be flush with the main body 31. Under the action of the telescopic spring 36, the plug 35 is pushed to reset and inserted into the positioning hole 33 again to fix the side plate 32. An active groove 38 that cooperates with the trigger block 37 is provided inside the main body 31 and at the bottom of the positioning groove 34 to provide space for the displacement of the trigger block 37.

[0024] In summary, when the movable folding steel frame for construction engineering is used, the slider 5 in the slide groove 4 in the mobile base 1 is pushed to move by the cylinder 6. Since the slider 5 is rotatably connected to one end of the two scissor-type telescopic frames 2, the slider 5 pushes the two scissor-type telescopic frames 2 to extend, and the multiple support plates 3 between the two scissor-type telescopic frames 2 are lifted and lowered accordingly and the spacing is pulled apart. At the same time, the multiple limiting frames 7 on the top of the mobile base 1 penetrate the limiting holes 8 at both ends of the multiple support plates 3. The multiple support plates 3 are limited by the multiple limiting frames 7 to remain flat. The height of the support plates 3 is adjusted according to the working position. At this time, climbing through the multiple support plates 3 allows you to stand at the lowest position. Work is carried out on the upper support plate 3. Since the support plate 3 is composed of a main body 31 and two side plates 32, and the main body 31 and the two side plates 32 are rotatably connected, when the support plate 3 needs to be folded to reduce the length of the support plate 3, the frame 71 in the main body 31 to be folded can be rotated in conjunction with the threaded connection between the multiple frames 71 to separate it from the lower frame 71. After it is pulled out from the limiting hole 8 in the main body 31, the plug 35 in the positioning groove 34 of the sliding main body 31 is displaced by the trigger block 37, so that one end of it is pulled out from the positioning hole 33 of the side plate 32, and the fixation of the side plate 32 is released, so that the side plate 32 can be flipped.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
