Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] This invention provides, for example Figure 1-7A combined scaffolding for building construction that is convenient for moving up and down, including a bottom plate 1. A notch 2 is provided inside the bottom plate 1, and a screw rod 4 is rotatably connected inside the notch 2. A fixing block 5 is movably sleeved on the outer ring of the screw rod 4. It further includes:

[0043] Lifting mechanisms 6, two groups in number. The second body block 602 is sleeved on the outer ring of the screw rod 4, and the first body block 601 is movably sleeved on the outer wall of the second body block 602;

[0044] Expansion mechanism 8. Above the bottom plate 1, there is a first workbench plate 801. A extension plate 12 is fixed to the bottom of the first workbench plate 801. A second workbench plate 802 is movably sleeved inside the first workbench plate 801. And a first mounting block 803 is fixed to the end of the second workbench plate 802. The first mounting block 803 is engaged with the inside of the second mounting block 804;

[0045] First support mechanism 9. Two fixed side plates 901 are fixed to the side wall of the extension plate 12. A first smooth rod 902 is fixed between the two fixed side plates 901. And a sloping plate 903 is fixedly sleeved on the outer ring of the first smooth rod 902. An obliquely fixed rod 904 is fixedly connected to the outside of the sloping plate 903;

[0046] Second support mechanism 10. Two pairs of symmetrical fixed side plates 1001 are fixedly connected to the top of the bottom plate 1 and the side wall of the second body block 602 respectively. A second smooth rod 1002 is fixed between the two fixed side plates 1001. And a cylinder 1003 is movably sleeved on the outer ring of the second smooth rod 1002. <000​​​​​​​​​​​​​Block 2 602 has an open cavity at the lower end, and the inner wall of the cavity of Block 2 602 is attached to the outer wall of Block 1 601 and is slidably connected to it, so as to facilitate the raising and lowering of Block 2 602.

[0052] Telescopic rod 603 is embedded inside block 1 601, and the top of telescopic rod 603 is fixedly connected to the top wall of the cavity inside block 2 602 to control the lifting and lowering of block 2 602;

[0053] The upright plate 604 is fixedly connected to the bottom of block 601, and the bottom of the upright plate 604 is attached to and slidably connected to the top wall of the base plate 1.

[0054] Cleaning brushes 7 are fixedly connected to the left and right sides of the protruding block 601, and the bristles of the cleaning brushes 7 cover the screw 4. During the rotation of the screw 4, the cleaning brushes 7 move in a straight line with the block 601, thereby cleaning the dust and impurities embedded in the threads of the rotating screw 4.

[0055] Extended mechanism 8 includes:

[0056] The workbench 801 has a cavity that runs through both the left and right ends, and triangular scrapers 11 are fixedly connected to both the left and right ends of the workbench 801.

[0057] There are two worktables 802, which are symmetrically distributed in the cavity of worktable 801. The bottom of the scraper 11 contacts the top of the worktable 802. The scraper 11 cleans the impurities and dust on the surface of the worktable 802 to prevent impurities and dust from entering the cavity of worktable 801 and affecting the expansion and contraction of worktable 802.

[0058] Mounting block 1 803 and mounting block 2 804 are fixedly connected to the bottom of one end of the worktable 2 802. Mounting block 1 803 matches the pre-set groove inside mounting block 2 804 fixed to the side wall of body block 2 602. This is used for the installation and subsequent disassembly of worktable 1 801 and worktable 2 802 with lifting mechanism 6.

[0059] The upper end of the inclined plate 903 is fixedly connected to the light rod 902 between the two fixed side plates 901 fixed at the bottom of the movable block 905, and the lower end of the inclined plate 903 is fixedly connected to the light rod 902 between the two fixed side plates 901 fixed at the side wall of the extension plate 12. The inclined plate 903 plays a supporting role in the expansion of the worktable plate 802.

[0060] The two ends of the inclined fixing rod 904 are fixedly connected to the bottom of the inclined plate 903 and the workbench plate 801, respectively, to fix the inclined plate 903 a second time, so that the inclined plate 903 has better support.

[0061] The movable block 905 has extension blocks fixed on both sides, and the movable block 905 can move within the preset movable groove 906 inside the workbench 802. When the workbench 802 is extended, it does not affect the support of the inclined plate 903 for the workbench 802.

[0062] The upper end of the cylinder 1003 is rotatably connected to the smooth rod 1002 between two fixed side plates 1001 fixed to the side wall of the second block 602 via a bearing, and the lower end of the cylinder 1003 is rotatably connected to the smooth rod 1002 between two fixed side plates 1001 fixed to the top of the base plate 1 via a bearing. The cylinder 1003 extends synchronously as the second block 602 rises. The cylinder 1003 supports the second block 602 and also supports and protects the entire lifting mechanism 6, making the use of scaffolding safer.

[0063] Working Principle: When using a modular scaffolding for easy vertical movement in construction, the motor 3 is first started, driving the output shaft of the motor 3 to drive the connecting screw 4 to rotate. Two sets of blocks 601 are respectively fitted onto the two opposite threaded outer rings of the screw 4. When the screw 4 rotates in opposite directions, the two sets of blocks 601 move towards or away from each other. At this time, when the two blocks 601 move away from each other, they drive the second block 602, which is movably fitted onto the outer ring of the first block 601, to move synchronously. Because the mounting block 803 fixedly connected to the end of the worktable 802 is engaged inside the mounting block 804 fixed to the side wall of the second block 602, the movement of the second block 602 drives the second worktable 802 to move synchronously. As 02 moves, the two sets of worktables 802 extend to both sides, thus expanding the overall area of ​​the scaffolding worktables. At the same time, when it is necessary to retract the worktables 802, the screw 4 rotates in the opposite direction, causing the two sets of blocks 601 to move towards each other, and similarly causing the two sets of blocks 602 to move towards each other. This causes the two worktables 802 to retract into the internal cavity of the worktable 801. At the same time, the scrapers 11 fixed at both ends of the worktable 801 come into contact with the surface of the worktables 802. The scrapers 11 remove impurities and dust from the surface of the worktables 802, ensuring that the movement of the worktables 802 inside the worktable 801 is not affected.

[0064] One side of the extension plate 12 fixed to the bottom of the workbench 801 is fixed with an inclined plate 903 by a fixed side plate 901 and a smooth rod 902. An inclined fixing rod 904 provides secondary fixation for the inclined plate 903. At the same time, the fixed side plate 901 and the smooth rod 902 at the upper end of the inclined plate 903 are fixed in the pre-set movable groove 906 inside the movable block 905. In this way, during the expansion of the workbench 802, the inclined plate 903 provides support to the bottom of the workbench 802, ensuring the stability and firmness of the workbench 802 in subsequent use.

[0065] When adjusting the overall height of the scaffold, the telescopic rod 603 is activated to extend outward, thereby driving block 602 to move upward. At the same time, as block 602 moves upward, cylinder 1003 extends synchronously. In this way, cylinder 1003 provides support for block 602 when it is raised to a certain height, and also provides support and protection for the entire lifting mechanism 6, making the use of the scaffold safer.

[0066] During the rotation of the screw 4, the cleaning brush 7 moves in a straight line along with the block 601, thereby cleaning the dust and impurities embedded in the threads of the rotating screw 4, ensuring that the block 601 moves more smoothly.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
