[0005] Therefore, a self-stabilizing external scaffolding structure that does not require wall attachment is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this utility model provides a wall-free, self-stabilizing external scaffolding structure, which has the advantages of easy connection and stable support.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A self-stabilizing external scaffolding structure that does not require wall attachment includes an outer protective frame, wherein the outer protective frame includes an upper protective frame and a lower protective frame, and a stabilizing mechanism is provided between the upper protective frame and the lower protective frame.

[0009] The stabilizing mechanism includes a first support column, a second support column, a tie wire rope, an inclined tie wire rope, and a fastening device for tightening the tie wire rope. The first support column and the second support column are arranged opposite to each other and installed between the upper and lower protective frames. The fastening device is installed on the second support column. One end of the tie wire rope is connected to the first support column, and the other end of the tie wire rope passes through the second support column and is connected to the fastening device. Both the first support column and the second support column are connected to the ground through the inclined tie wire rope.

[0010] Furthermore, the fastening device includes an L-shaped plate, a motor, and a winding rod for winding the pull wire rope. The L-shaped plate is fixedly connected to the outer side of the second support column, the motor is fixedly connected to the outer side of the L-shaped plate, the output end of the motor is fixedly connected to the winding rod, and the pull wire rope is wound around the winding rod.

[0011] Furthermore, the upper and lower protective frames are provided with grooves inside, and the first and second support columns are movably inserted into the grooves. The second support column is connected to a locking device for locking the second support column onto the lower protective frame.

[0012] Furthermore, the locking device includes a connecting plate, a threaded tube, a screw, and a positioning rod. The connecting plate is fixedly connected to the outer side of the second support column, the threaded tube is fixedly connected to the bottom of the connecting plate, the screw is threadedly connected to the inside of the threaded tube, and the positioning rod is fixedly connected to one end of the screw near the lower protective frame.

[0013] Furthermore, one end of the pull wire rope passes through the first support column and is connected to a retaining ring for abutting against the side wall of the first support column, and the other end of the pull wire rope movably passes through the second support column and is connected to the gathering rod.

[0014] Furthermore, the gathering rod is rotatably connected to the outside of the second support column, and the gathering rod is located above the pull wire rope.

[0015] Furthermore, both the upper and lower ends of the first support column and the second support column are fixedly connected to sliders, and the first support column and the second support column are slidably connected in the groove through the sliders.

[0016] Furthermore, the threaded pipe is fixedly connected to the outside of the second support column via the connecting plate, and the positioning rod is located on the outside of the lower protective frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) By setting up an upper and lower protective frame, the first and second support columns are first installed between the upper and lower protective frames. At this time, the tie wire rope passes through the second support column and moves to the outside of the gathering rod. Then, by winding the tie wire rope around the outside of the gathering rod, the motor is started, so that the motor drives the gathering rod to rotate. The rotation of the gathering rod tightens the tie wire rope wound around its outside, so that the tie wire rope is in a taut state, thereby achieving stable support for the scaffold.

[0019] (2) This utility model sets up an upper protective frame and a lower protective frame. Since the first support column and the second support column are installed between the upper protective frame and the lower protective frame, when it is necessary to adjust the position of the first support column and the second support column, the slider moves inside the groove, so that the first support column and the second support column can move between the upper protective frame and the lower protective frame. When it moves to the appropriate position, the screw is rotated, so that the screw rotates inside the threaded tube. At this time, the screw will drive the positioning rod to move, so that the positioning rod moves to abut against the lower protective frame, thereby achieving the positioning effect of the first support column and the second support column.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides a wall-free self-stabilizing external scaffolding structure. The wall-free self-stabilizing external scaffolding structure includes an outer protective frame 100, which includes an upper protective frame 1 and a lower protective frame 2. A stabilizing mechanism 3 is provided between the upper protective frame 1 and the lower protective frame 2.

[0030] The stabilizing mechanism 3 includes a first support column 31, a second support column 32, a tie wire rope, an inclined tie wire rope, and a fastening device for tightening the tie wire rope. The first support column 31 and the second support column 32 are arranged opposite to each other and installed between the upper protective frame 1 and the lower protective frame 2. The fastening device is installed on the second support column 32. One end of the tie wire rope 33 is connected to the first support column 31, and the other end of the tie wire rope 33 passes through the second support column 32 and is connected to the fastening device. Both the first support column 31 and the second support column 32 are connected to the ground through the inclined tie wire rope 33.

[0031] In one embodiment, the aforementioned fastening device includes an L-shaped plate 34, a motor 35, and a winding rod 36 for winding the pull wire rope 33. The L-shaped plate 34 is fixedly connected to the outer side of the second support column 32, and the motor 35 is fixedly connected to the outer side of the L-shaped plate 34. The output end of the motor 35 is fixedly connected to the winding rod 36, and the pull wire rope 33 is wound around the winding rod 36. Specifically, one end of the pull wire rope 33 passes through the first support column 31 and is connected to a retaining ring (not shown in the figure) for abutting against the side wall of the first support column 31. The other end of the pull wire rope 33 movably passes through the second support column 32 and is connected to the winding rod 36. The winding rod 36 is rotatably connected to the outer side of the second support column 32 and is located above the pull wire rope 33. By driving the motor to rotate the winding rod 36, the pull wire rope is tightened and placed in a taut state.

[0032] Furthermore, the upper protective frame 1 and the lower protective frame 2 have grooves 41 inside. The first support column 32 and the second support column 32 are movably inserted into the grooves 41. A locking device for locking the second support column 32 onto the lower protective frame 2 is connected to the second support column 32. In one embodiment, the locking device includes a connecting plate 43, a threaded tube 44, a screw 45, and a positioning rod 46. The connecting plate 43 is fixedly connected to the outer side of the second support column 32, and the threaded tube 44 is fixedly connected to the bottom of the connecting plate 43. The screw 45 is threadedly connected to the inside of the threaded tube 44, and the positioning rod 46 is fixedly connected to one end of the screw 45 near the lower protective frame 2. By moving the second support column 32 to a position opposite to the first support column 32, the positioning rod 46 is moved closer to the second support column 32 and abuts against the second support column 32 by rotating the screw 45, thereby positioning the second support column 32.

[0033] The first support column 31 and the second support column 32 are evenly distributed between the upper protective frame 1 and the lower protective frame 2, and the first support column 31 and the second support column 32 can provide support for the upper protective frame 1 and the lower protective frame 2.

[0034] Furthermore, the pull wire rope 33 passes through the interior of the second support column 32, and one end of the pull wire rope 33 away from the first support column 31 moves through to the outside of the second support column 32. By tightening the pull wire rope 33, the first support column 31 can exert a force that moves closer to the second support column 32.

[0035] Both the upper and lower ends of the first support column 31 and the second support column 32 are fixedly connected to sliders 42. The sliders 42 are fixedly connected to the upper and lower ends of the first support column 31 and the second support column 32, and the first support column 31 and the second support column 32 are movably connected between the upper protective frame 1 and the lower protective frame 2 through the sliders 42. The first support column 31 and the second support column 32 can move by the sliders 42 moving inside the groove 41.

[0036] The threaded tube 44 is fixedly connected to the outside of the second support column 32 through the connecting plate 43. The positioning rod 46 is located on the outside of the lower protective frame 2. It rotates on the threaded tube 44 through the screw 45, thereby causing the screw 45 to drive the positioning rod 46 to move to the outside of the lower protective frame 2, so that the positioning rod 46 can be pressed against the lower protective frame 2.

[0037] It should be noted that: the internal structure is connected to the outer guardrail 100 by tie-down steel wire rope 33, and the external structure is pulled to the ground by diagonal steel wire rope 5, thus forming a stable whole, so that the tie-down steel wire rope 33 and the diagonal steel wire rope 5 are in a taut state.

[0038] In summary, this utility model, by setting up an upper protective frame 1 and a lower protective frame 2, firstly installs the first support column 31 and the second support column 32 between the upper protective frame 1 and the lower protective frame 2. At this time, one end of the pull wire rope 33 is connected to the first support column 31, and the other end of the pull wire rope 33 passes through the second support column 32 so that it extends to the outside of the retracting rod 36. Then, by winding the pull wire rope 33 around the outside of the retracting rod 36, the motor 35 on the outside of the L-shaped plate 34 is started, so that the motor 35 drives the retracting rod 36 to rotate. The rotation of the retracting rod 36 tightens the pull wire rope 33 wound around its outside, so that the pull wire rope 33 is in a taut state. Furthermore, the first support column 31 and the second support column 32 are connected to the ground through the diagonal pull wire rope 5, so that the diagonal pull wire rope 5 is in a taut state. The scaffolding is kept taut to achieve stable support. An upper protective frame 1 and a lower protective frame 2 are installed. Since the first support column 31 and the second support column 32 are installed between the upper protective frame 1 and the lower protective frame 2, when the positions of the first support column 31 and the second support column 32 need to be adjusted, the slider 42 moves inside the groove 41, allowing the first support column 31 and the second support column 32 to move between the upper protective frame 1 and the lower protective frame 2. When they reach the appropriate position, the screw 45 is rotated, causing it to rotate on the threaded tube 44. This screw 45 then moves the positioning rod 46, causing it to move to the outside of the lower protective frame 2 and abut against it, thus positioning the first support column 31 and the second support column 32.
