Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0022] like Figures 1-3 As shown, an adjustable base for scaffolding includes a fixed base 1, a left roller assembly 2, a right roller assembly 3, and a power unit 4;

[0023] The fixed base 1 is used to connect to the upright of the scaffold. The left end and the right end are respectively provided with a left connecting groove 11 and a right connecting groove 12. The left connecting groove 11 and the right connecting groove 12 are respectively rotatably provided with a first threaded rod 13 and a second threaded rod 14, and the first threaded rod 13 and the second threaded rod 14 are vertically arranged.

[0024] Left roller assembly 2 is screwed to the first threaded rod 13;

[0025] Right roller assembly 3 is screwed to the second threaded rod 14;

[0026] The power assembly 4 is located on the upper part of the fixed base 1 and is used to drive the first threaded rod 13 and the second threaded rod 14 to rotate in the same direction, so that the left roller assembly 2 and the right roller assembly 3 move downward to contact the ground or move upward away from the ground.

[0027] When using this device, the fixed base 1 is set below the uprights of the scaffold and is used to connect with the scaffold, so that the entire scaffold and the fixed base are connected to form a whole and move together. First, the first threaded rod 13 and the second threaded rod 14 are respectively set at the left and right ends of the fixed base 1. The left roller group 2 and the right roller group 3 are screwed to the first threaded rod 13 and the second threaded rod 14 respectively. When it is necessary to adjust the position of the fixed base 1, the power component 4 is started to drive the first threaded rod 13 and the second threaded rod 14 to rotate. Since the left roller group 2 and the right roller group 3 are screwed to the first threaded rod 13 and the second threaded rod 14, they move down along the first threaded rod 13 and the second threaded rod 14. The left roller group 2 and the right roller group 3 slide in contact with the ground and are adjusted according to the construction progress and operation requirements. When no movement is required, the power unit 4 drives the first threaded rod 13 and the second threaded rod 14 to rotate in opposite directions. The left roller group 2 and the right roller group 3 move upward and retract to disengage from the ground. At this time, the fixed seat 1 plays a role in fixed support, realizing the switching between walking mode and fixed mode, solving the problem of the scaffold being difficult to adjust its position, and also ensuring the support effect.

[0028] like Figure 1 and Figure 2As shown, in a preferred embodiment, the power assembly 4 includes a motor 41, a first pulley 42, and a second pulley 43. The motor 41 is located on the upper right side of the fixed base 1, and its output shaft passes downward through the fixed base 1 to connect to the second threaded rod 14. The first pulley 42 is mounted on the output shaft of the motor 41. The second pulley 43 is located on the upper left side of the fixed base 1, and the first threaded rod 13 passes through the upper part of the fixed base 1 to connect to the second pulley 43. The second pulley 43 and the first pulley 42 cooperate. In this embodiment, when the motor 41 is started, it drives the second threaded rod 14 to rotate. Since the first pulley 42 is mounted on the output shaft of the motor 41, it also rotates when the motor 41 is started. Transmission occurs between the first pulley 42 and the second pulley 43 via a belt. The second pulley 43 rotates together with the first pulley 42 under the drive of the belt, driving the first threaded rod 13 to rotate. At this time, the first threaded rod 13 and the second threaded rod 14 rotate in the same direction, driving the left roller group 2 and the right roller group 3 to move.

[0029] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the left roller group 2 and the right roller group 3 have the same structure. The left roller group 2 includes a first roller 21, a second roller 22, and a connecting plate 23. The first roller 21 is located at the front end of the connecting plate 23, and the second roller 22 is located at the rear end of the connecting plate 23. The first threaded rod 13 passes through the front end of the connecting plate 23. In this embodiment, the left roller group 2 is provided with a first roller 21 and a second roller 22. The two rollers can better contact the ground and maintain balance. The connecting plate 23 is provided between the first roller 21 and the second roller 22. The connecting plate 23 can strengthen the connection between the first roller 21 and the second roller 22, improve the stability of the structure, and also ensure that the first roller 21 and the second roller 22 rise and fall synchronously.

[0030] like Figure 1 and Figure 2 As shown, in a preferred embodiment, a limiting rod 5 is also included. The limiting rod 5 is vertically disposed at the rear end of the left connecting groove 11 and passes through the rear end of the connecting plate 23. The connecting plate 23 can move up and down along the limiting rod 5. In this embodiment, since the first roller 21 and the second roller 22 are respectively disposed at the front end and the rear end of the connecting plate 23, in order to ensure the stability of the structure, a limiting rod 5 is disposed at the rear end of the left connecting groove 11. The limiting rod 5 serves the same function as the support for the rear end of the connecting plate 23 as the first threaded rod 13, and the connecting plate 23 can also move up and down along the limiting rod 5.

[0031] like Figure 1 and Figure 2As shown, in a preferred embodiment, a storage drawer 6 is also included, disposed at the front end of the fixing base 1 and inserted into the fixing base 1 for storage. In this embodiment, loose items used during scaffolding construction are placed in the storage drawer 6 for storage, and the storage drawer 6 can be directly inserted into the fixing base 1 without occupying space.

[0032] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the storage drawer 6 is provided with a handle 7. In this embodiment, the construction worker can better control the pushing and pulling of the storage drawer 6 by using the handle 7.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the fixing base 1 has a sliding groove 15 inside, and the left and right ends of the storage drawer 6 are respectively provided with sliders 61 that match the sliding groove 15. In this embodiment, the fixing base 1 has a sliding groove 15 inside, and sliders 61 are provided on both sides of the storage drawer 6. By using the sliders 61 and the sliding groove 15 in cooperation, it is more effortless to use the storage drawer 6.
