Description

Technical Field

[0001] This utility model is an electrically adjustable top and bottom support device, belonging to the field of building engineering technology. Background Technology

[0002] In the early 1980s, my country began importing various types of scaffolding from abroad, including frame scaffolding and cup-lock scaffolding. These scaffolding systems were considered very advanced construction equipment at the time. Frame scaffolding, due to its unique structure and stability, was widely used in many domestic engineering projects and achieved satisfactory results. However, due to some quality problems in the production process of frame scaffolding, it failed to achieve large-scale promotion and application in China.

[0003] With the continuous emergence of numerous modern large-scale building systems in my country, traditional coupler-type steel pipe scaffolding can no longer meet the needs of current construction development. Practice has proven that using disc-lock scaffolding not only ensures the safety and reliability of the construction process but also offers significant advantages in assembly and dismantling speed. Using disc-lock scaffolding can effectively reduce the amount of steel used in scaffolding, increase assembly and dismantling efficiency by more than two times, thereby significantly reducing construction costs. Furthermore, the level of civility and cleanliness of the construction site is also significantly improved.

[0004] However, in the actual erection of modular scaffolding, the adjustment process of the adjustable top and bottom supports is quite complex and time-consuming. This complexity not only increases the time required for the operation but also raises the difficulty of the work. Specifically, when adjusting these adjustable components, workers often need to carefully adjust every bolt and knob to ensure the stability and safety of the scaffolding. This process requires not only extensive experience and skill but may also lead to repeated adjustments due to minor errors. Therefore, although adjustable top and bottom supports theoretically offer flexibility and adaptability, in practice they bring additional challenges and burdens to the construction.

[0005] In conclusion, although modular scaffolding offers certain advantages over traditional coupler-type scaffolding during erection, some problems still exist in actual practice. Fine adjustments to each top or bottom support are required to ensure the overall structural stability and safety, which undoubtedly increases construction time costs. Therefore, despite its advantages in some aspects, the erection speed of modular scaffolding is still limited in practical applications, which needs to be fully considered and optimized during construction.

[0015] Preferably, the limiting structure further includes a locking element; the locking element is inserted into several notches located on the fixing element, so that the fixing element is fixed to the top support or the bottom support.

[0016] Preferably, the bottom of the top support has a scaffolding connector for connecting the top support to the scaffolding.

[0017] Preferably, the fastener is plate-shaped, for engaging with the teeth of the second bevel gear.

[0018] Preferably, both the first bevel gear and the second bevel gear are rotatably mounted on the top support or the bottom support via bearings.

Attached Figure Description

[0021] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0022] Figure 1 This is a schematic diagram of the structure of an electrically adjustable base device according to the present invention;

[0023] Figure 2 This is a schematic diagram of the structure of an electrically adjustable top support device according to the present invention. Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] Please see Figure 1 The base 1 is hollow; the support rod 3 is inserted into the base 1 and threadedly connected to the sleeve 4; the gear set 6 consists of two meshing first bevel gears 61 and second bevel gears 62, and the second bevel gear 62 is fixedly connected to the support rod 3; the limiting structure 5 includes a fixing member 51; the fixing member 51 extends into the base 1 to fix the second bevel gear 62.

[0027] Working principle: By rotating the first bevel gear 61, the second bevel gear 62 is driven to rotate accordingly; the rotation of the second bevel gear 62 drives the sleeve 4 to rotate. Since the support rod 3 is threadedly connected to the sleeve 4, and the sleeve 4 is rotatably connected to the base 1, the rotation of the sleeve 4 will drive the support rod 3 to move up and down.

[0028] To enable the rotation of the first bevel gear 61, a drive shaft 7 is provided on the first bevel gear 61; the drive shaft 7 has a threaded notch and extends out of the base 1; an existing electric screwdriver 10 is used to contact the threaded notch of the drive shaft 7, so that the electric screwdriver 10 drives the drive shaft 7 to rotate, thereby driving the first bevel gear 61 to rotate.

[0029] Furthermore, to achieve an effective connection between the second bevel gear 62 and the sleeve 4, the second bevel gear 62 is horizontally positioned and fixedly connected to the sleeve 4 via a connecting rod 9; this allows the sleeve 4 to rotate with the second bevel gear 62.

[0030] Furthermore, to prevent the drive shaft 7 from being damaged or interfered with by external factors during use, the drive shaft 7 is covered with a protective shell 8. The protective shell 8 isolates and protects the drive shaft 7. In order to allow the electric screwdriver 10 to contact the drive shaft 7 through the protective shell 8, the protective shell 8 has an opening for the electric screwdriver 10 to extend into, so that the electric screwdriver 10 can connect to the drive shaft 7 through the opening.

[0031] Furthermore, to ensure that the load-bearing rod 3 does not shift position during use, the limiting structure 5 includes a fixing member 51. The fixing member 51 extends into the base 1 to fix the second bevel gear 62. The fixing member 51 is plate-shaped, designed to engage with the teeth of the second bevel gear 62. This prevents the second bevel gear 62 from rotating, thereby preventing displacement of the load-bearing rod 3. Preferably, the limiting structure 5 also includes a locking member 52. The locking member 52 is inserted into several notches on the fixing member 51 to fix the fixing member 51 to the base 1, thus preventing the fixing member 51 from falling off the base 1.

[0032] Furthermore, to ensure the normal operation of the first bevel gear 61 and the second bevel gear 62, both the first bevel gear 61 and the second bevel gear 62 are rotatably mounted on the sleeve 4 via bearings, enabling them to rotate normally.

[0033] Example 2

[0034] See Figure 2 The difference from Embodiment 1 is that the bottom support 1 is replaced with the top support 2; the bottom of the top support 2 has a scaffolding connector 11 for connecting the top support 2 to the scaffolding.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
