[0023] 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.

[0024] Example 1

[0025] Please refer to Figure 1-5 As shown, this utility model provides a support structure for an attached lifting scaffold, including a back plate 1. Two sets of cantilever arms 3 are provided on one side of the back plate 1. The two sets of cantilever arms 3 are connected by a vertical plate 5. A movable seat 7 is slidably connected to the top of the two sets of cantilever arms 3. One side of the vertical plate 5 is connected to the movable seat 7 through an adjustment mechanism that facilitates position adjustment. A connecting plate 12 is installed at one end of the movable seat 7. Anti-tilt frames 13 are installed on one side of the connecting plate 12 near both ends. Mounting grooves 14 are opened on the inner walls of both sides of the two sets of anti-tilt frames 13. Two sets of guide wheels 15 are rotatably connected to the inner side of the mounting grooves 14. A groove 16 is provided on one side of the connecting plate 12 between the two sets of anti-tilt frames 13. A fall-prevention swing block 17 is rotatably connected to the inner side of the groove 16. An anti-fall swing block 17 is provided at the bottom of the fall-prevention swing block 17. A fixing plate 19 is provided on the inner side of the groove 16 near the bottom. A support block 20 that cooperates with the abutment block 18 is provided on its top. An adjustable-length top support mechanism is hinged to the top of the movable seat 7.

[0026] Specifically, the back plate 1 is fixed to the building wall, the cantilever 3 is connected by the upright plate 5 to form a stable support frame, the movable seat 7 can slide on the top of the cantilever 3, and by operating the adjustment mechanism, the movable seat 7 can be moved to a suitable position according to the actual construction situation, thereby changing the position of the anti-tilt frame 13 and the anti-falling swing block 17, ensuring that the attached lifting scaffold can be stably supported in different positions. The anti-tilt frame 13 has a guide wheel 15 rotatably connected inside the mounting groove 14, which can reduce friction and ensure smooth lifting of the scaffold, while preventing the scaffold from tilting during lifting. The anti-falling swing block 17 is located in the groove 16. When used in conjunction with the support block 20 on the fixed plate 19, in the event of an accidental fall of the scaffold, the contact block 18 at the bottom of the anti-fall swing block 17 will contact and abut against the support block 20, thereby preventing the scaffold from falling further and ensuring construction safety. By adjusting the length of the top support mechanism, it can be made to abut against a specific part of the scaffold, providing additional support force to the support structure and further enhancing the stability of the support structure. Thus, through the above structure, the functions of stable support, anti-overturning, and anti-fall of the scaffold are achieved. At the same time, the position of the support structure can be flexibly adjusted according to the actual building conditions, greatly improving the applicability of the device.

[0027] The adjustment mechanism includes a knob 9. Each of the two sets of cantilever arms 3 has a groove 6 on one side. The two ends of the movable seat 7 are slidably connected to the two sets of grooves 6 respectively. A screw 8 is rotatably connected to one side of the upright plate 5. One end of the screw 8 is threadedly connected to the movable seat 7, and the other end of the screw 8 passes through the interior of the upright plate 5 and is connected to the knob 9. An operating cavity is formed between the upright plate 5 and the back plate 1 to facilitate the rotation of the knob 9. By rotating the knob 9, the knob 9 drives the screw 8 to rotate. According to the principle of screw drive, since the movable seat 7 and the screw 8 are threadedly engaged, the rotation of the screw 8... This causes the movable seat 7 to move linearly along the axis of the screw 8. This transmission method can accurately convert the rotational motion of the knob 9 into the linear displacement of the movable seat 7, thereby realizing the adjustment of the position of the movable seat 7. The two sets of sliding grooves 6 provide guidance for the movement of the movable seat 7, ensuring that the movable seat 7 can only move along the direction of the sliding grooves 6 without deviation or shaking, thus ensuring the stability and accuracy of the adjustment process. Furthermore, by setting it up, the position of the support structure can be flexibly adjusted according to the actual building conditions, greatly improving the applicability of the device.

[0028] The tops of the two sets of cantilever arms 3 and the tops of the movable seat 7 near both ends are provided with through slots 10. The two sets of cantilever arms 3 and the movable seat 7 are connected by two sets of fastening bolts 11 that pass through the inner sides of the corresponding two sets of through slots 10. The through slots 10 are straight grooves. When the fastening bolts 11 pass through the inner sides of the corresponding two sets of through slots 10 and the nuts are tightened, the fastening bolts 11 will generate axial tension. This tension makes the cantilever arms 3 and the movable seat 7 fit tightly together, using friction to resist external forces that may cause them to move relative to each other, thereby achieving a reliable connection and fixation between the cantilever arms 3 and the movable seat 7, and ensuring the stability of the movable seat 7 after position adjustment.

[0029] The top support mechanism includes a top support block 24. A rotating plate 22 is hinged to the top of the movable seat 7. One end of the rotating plate 22 is threadedly connected to an adjusting screw 26, and the other end of the adjusting screw 26 is threadedly connected to a connecting cylinder 23. A rotating cylinder 25 is provided in the middle section of the adjusting screw 26 to facilitate its rotation. The other end of the connecting cylinder 23 is connected to the top support block 24. By rotating the rotating cylinder 25, the adjusting screw 26 can be driven to rotate. Since the adjusting screw 26 is threadedly engaged with the rotating plate 22 and the connecting cylinder 23, according to the screw drive principle, the rotation of the adjusting screw 26... The movement is transformed into relative linear motion between the adjusting screw 26, the rotating plate 22, and the connecting cylinder 23. By changing the rotation direction of the adjusting screw 26, the connecting cylinder 23 can be lengthened or shortened relative to the rotating plate 22, thereby adjusting the overall length of the top support mechanism. The rotating plate 22 is hinged to the top of the moving seat 7. This hinge structure allows the rotating plate 22 to rotate within a certain range around the hinge point, so that the top support mechanism can adjust the angle according to actual needs to adapt to different support positions and directions, increasing the flexibility and applicability of the top support mechanism.

[0030] The groove 16 has a limiting plate 21 near the top on its inner side to restrict the rotation range of the anti-fall swing block 17. The limiting plate 21 restricts the rotation range of the anti-fall swing block 17 and prevents it from rotating excessively. The back plate 1 is made of high-strength steel plate with anti-corrosion treatment. This design improves its overall strength, effectively enhances its corrosion resistance, and extends its service life. The bottoms of both cantilever arms 3 are connected to the back plate 1 via support plates 4. The support plates 4 serve to connect and reinforce the cantilever arms 3 and the back plate 1, tightly combining them to form a stable triangular structure.

[0031] Among them, a steel pad 27 is provided on one side of the back plate 1. The back plate 1 and the steel pad 27 are provided with mounting holes 2 near the upper and lower ends to facilitate the passage of bolts. The steel pad 27 optimizes the construction process of drilling and repairing holes, can replace traditional concrete, reduces repairs, is simple to operate, and has low safety risks. The main function of the mounting hole 2 is to fix the support structure to the building wall.

[0032] Working Principle: First, through the coordinated work of the back plate 1, cantilever 3, upright plate 5, movable seat 7, anti-tilting frame 13, guide wheel 15, anti-falling swing block 17, top support mechanism, and adjustment mechanism, the scaffolding can achieve stable support, anti-tipping, and anti-falling functions. When it is necessary to adjust the position of the support structure, by turning the knob 9, the knob 9 can drive the screw 8 to rotate. The rotation of the screw 8 will cause the movable seat 7 to move linearly along the axis of the screw 8. This transmission method can accurately convert the rotation of the knob 9 into the linear displacement of the movable seat 7, thereby realizing the adjustment of the position of the movable seat 7. The two sets of sliding grooves 6 provide guidance for the movement of the movable seat 7, ensuring that the movable seat 7 can only move along the direction of the sliding grooves 6 without deviation or shaking, ensuring the stability and accuracy of the adjustment process. Thus, the position of the support structure can be flexibly adjusted according to the actual building conditions, greatly improving the applicability of the device and completing the entire operation process.
