[0033] The present invention will be further described below through specific embodiments.

[0034] Example 1

[0035] In this embodiment, combined with the attached Figure 1 The scaffolding support system of the utility model is composed of only one scaffolding support device. The scaffolding support device includes four retractable support rods 1, a cross frame 4, a connecting piece 3, a strut 5, a driving mechanism 2 and a fixing plate 6, which surround the scaffolding support device into a square structure. The four retractable support rods 1 are respectively located at the four corners of the scaffolding support device. A connecting piece 3 is detachably connected to the upper end of any one of the retractable support rods 1 by means of threads or bolts. The connecting piece 3 is fixedly connected to the cross frame 4 arranged at the upper end of the scaffolding support device. The inner sides of two adjacent cross frames 4 are fixed by struts 5. A driving mechanism 2 is installed on the retractable support rod 1, and a fixing plate 6 is fixed to the lower end of the retractable support rod 1.

[0036] According to an embodiment of the utility model, the telescopic support rod 1 can be a three-section telescopic square tube. In addition, a mounting hole is welded on the inner side of the cross frame 4, and its main function is to install the support rod 5 to improve the stability of the top surface of the entire system. Furthermore, the connecting member 3 includes a mounting tube, a fixed tube and a mounting chassis. The fixed tube is welded at the center of the mounting chassis and connected to the cross frame 4 by bolts; the mounting tubes are evenly distributed around the fixed tube for welding, and their main function is to install the cross frame 4.

[0037] Specifically, during the assembly of the scaffolding support system, the connecting piece 3 is first installed on the upper end of the telescopic support rod 1 by bolt connection; the lower end of the telescopic support rod 1 is fixed to a suitable position on the ground according to the length of the cross frame 4; the two ends of the cross frame 4 are respectively connected to the upper ends of the two adjacent telescopic support rods 1 through the connecting piece 3 and fastened with bolts; the two ends of the support rod 5 are respectively inserted into the mounting holes of the two adjacent cross frames 4, and the mounting holes are opened on the horizontal tube of the cross frame 4.

[0038] According to the embodiment of the utility model, according to the use requirements, the fixing plate 6 can also be fixed to the ground using expansion bolts, and then one end of the telescopic support rod 1 can be fixed to the fixing plate 6.

[0039] Regarding the length design of the cross frames 4 on the four sides, the lengths of the two corresponding parallel cross frames 4 are the same.

[0040] Example 2

[0041] The following will take the two-span scaffolding support system as an example to describe:

[0042] The shelf support system in this embodiment is formed by two shelf support devices being fixedly connected. Each shelf support device includes four retractable support rods 1, a cross frame 4, a connecting piece 3, a support rod 5, a driving mechanism 2 and a fixing plate 6. The two shelf support devices share two retractable support rods 1 in the same direction and are fixedly connected by the connecting piece 3 connected to the retractable support rods 1. Specifically, the cross frames 4 on two adjacent shelf support devices are respectively fixedly connected by the same connecting piece 3. The shelf support system is enclosed into a rectangular structure.

[0043] In this embodiment, before the scaffolding support system is raised or lowered, the scaffolding support system needs to be moved to a suitable position according to the on-site usage, and the fixing plate 6 connected to the lower end of the telescopic support rod 1 is fixed to the ground through expansion bolts. Then, according to the area surrounded by the multiple telescopic support rods 1, the multiple support rods 5 are stretched to a suitable length, that is, the support rods 5 can be extended. Then, the multiple cross frames 4 are connected through the multiple connecting members 3, and the support rods 5 are connected at the horizontal pipe positions of the multiple cross frames 4.

[0044] like Figure 2As shown, when the scaffolding support system is in the lifting operation, the operator stands on the side of the scaffolding support system and operates the motor 6 through the wireless controller. The motor 6 drives the reel 7 to rotate, and the reel 7 rotates to reel in the wire rope, driving the retractable support rod 1 to start extending at a uniform speed until the retractable support rod 1 extends to a suitable position, that is, reaches the height desired by the user.

[0045] like Figure 3 As shown, when the scaffolding support system is retracting, the operator operates the motor 6 through the wireless controller, and the motor 6 drives the drum 7 to rotate, and the drum 7 rotates to release the wire rope, driving the telescopic support rod 1 to retract at a uniform speed until the telescopic support rod 1 retracts to a suitable position. The uniform speed retraction can ensure a smooth retraction process.

[0046] It is worth noting that before the scaffolding support system is lowered, it should be ensured that the objects placed or the people standing in the internal space of the scaffolding support system have been evacuated and the power supply of the motor 6 is normal.

[0047] According to an embodiment of the utility model, when the motor 6 cannot supply power normally, at this time, the handle ratchet and the drum 8 are in a connected state, and the drum 8 can be driven to rotate by rotating the handle 9, thereby completing the release or contraction of the wire rope, thereby completing the contraction and raising of the scaffolding support system.

[0048] According to the embodiment of the utility model, when the motor does not work or the handle does not rotate, the wire rope is in a fixed state.
