Description

Technical Field

[0001] This utility model relates to the field of semiconductor workshop maintenance technology, specifically a foldable scaffold. Background Technology

[0002] In semiconductor workshops, high-altitude operations such as equipment installation and debugging, and circuit laying and maintenance are frequent. Although traditional scaffolding is commonly used, its drawbacks are significant.

[0003] Its fixed height, typically with only two preset heights, makes it difficult to match the diverse height requirements of semiconductor equipment. Workers must frequently change heights or use auxiliary tools, resulting in low efficiency and high risk. In terms of safety, the operating platform lacks guardrails and measures to prevent items from falling. In workshops with high cleanliness and equipment precision requirements, falling tools can damage equipment and threaten personnel safety. Structurally, the folding parts are simply connected, and frequent folding and unfolding can easily loosen them, posing a significant safety hazard under heavy loads and failing to meet the demands of high-intensity, high-precision operations. During handling and storage, its large size and difficulty in folding make it inconvenient to move within the limited space of a workshop, occupying a large amount of storage space. Constructing complex, large scaffolding also consumes significant manpower and time, hindering production efficiency.

[0004] Therefore, it is essential to develop scaffolding that is height-adjustable, has comprehensive safety features, a stable structure, and is easy to transport, store, and assemble. This foldable scaffolding was developed to meet this need. Utility Model Content

[0005] To address the problems of the prior art, this utility model provides a foldable scaffold.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a foldable scaffold, including a first support body, with foldable legs hinged to the inner side of the bottom support legs of the first support body, and a locking structure provided between the support legs and the foldable legs for locking and fixing the foldable legs in the open or retracted state.

[0007] Both ends of the first support body are fixedly connected to ladder frames. A sliding seat is slidably connected to the outer wall of the ladder frame. A locking structure is provided between the sliding seat and the ladder frame for locking the sliding seat after it slides to a predetermined position on the outer wall of the ladder frame. A ladder is inserted into the inner side of the sliding seat for workers to climb into the interior of the first support body.

[0008] A main pedal is fixedly connected to the bottom inner side of the first support body. Side plates are hinged to both sides of the first support body. A first telescopic rod is hinged to the inner side of the side plate. The output end of the first telescopic rod is hinged to the first support body. The opening angle of the side plate is further controlled by controlling the extension length of the first telescopic rod. A first end plate is hinged to both ends of the first support body. A locking structure is provided between the end of the first end plate away from the hinge end and the first support body for locking or opening the first end plate.

[0009] The top four corners of the first support body are fixedly connected with second telescopic rods, and the output ends of the four second telescopic rods are fixedly connected to the protective rod. The protective height of the protective rod can be adjusted by controlling the extension and retraction length of the second telescopic rods.

[0010] This application presents a foldable scaffolding designed to address the problems of complex erection, poor flexibility, and insufficient safety associated with traditional scaffolding. Through a series of innovative designs, it achieves convenient folding, storage, and transportation of the scaffolding, improving stability and safety during use. It can adapt to various work scenarios, significantly enhancing work efficiency and ease of operation for construction workers.

[0011] In some specific implementations, the bottom ends of the first support legs of the first bracket body are all fixedly connected to the first universal wheels, and the bottom ends of the multiple folding legs are all fixedly connected to the second universal wheels.

[0012] The bottom of each of the first support legs of the main frame is fixedly connected to a first swivel caster, and the bottom of each of the multiple folding support legs is fixedly connected to a second swivel caster. This design provides the scaffolding with excellent mobility, facilitating rapid relocation between different construction sites, reducing the difficulty and cost of manual handling, and improving work efficiency. The swivel casters allow for easy changes in the direction of scaffolding movement, adapting to various complex construction site environments.

[0013] In some specific implementations, the bottom end of the folding leg is snapped with a support frame, and the bottom end of the support frame is set as an adjustable leg to keep it close to the ground, increase the overall support area of ​​the equipment, and improve the stability of the equipment.

[0014] The bottom of the folding outriggers is attached to a support frame, and the bottom of the support frame is designed as an adjustable outrigger to ensure close contact with the ground, increasing the overall support area of ​​the equipment and improving its stability. The effect is that when the scaffolding is deployed, the adjustable outriggers can be adjusted according to the actual ground conditions, ensuring that each support point is in close contact with the ground, effectively preventing the scaffolding from swaying or tipping over during use, and protecting the personal safety of construction workers.

[0015] In some specific implementations, the locking structure between the first support body and the folding leg is fixedly connected by bolts;

[0016] The locking structure between the main support structure and the folding legs uses bolts for fixing. The advantage of using bolts is that the connection is strong and reliable, maintaining a stable connection in both the unfolded and folded states of the scaffolding. This prevents the folding legs from loosening due to accidental stress, ensuring the structural stability of the scaffolding during use.

[0017] In some specific implementations, the sliding seat has a plug rod on its inner side, and the top of the ladder has plug holes on both sides. The plug rod and the plug holes are connected by a plug-in joint. This connection method facilitates quick installation and disassembly of the ladder by workers, allows for easy adjustment of the ladder's position as needed, improves the convenience of scaffolding use, and also ensures the ladder is stable and reliable during use, preventing slippage.

[0018] In some specific implementations, the locking structure between the first end plate and the first bracket body is fixedly connected by a pin.

[0019] The locking structure between the first end plate and the first support body uses a pin-type connection. The pin connection is simple and convenient to operate, and can quickly lock and open the first end plate. When it is necessary to enter the first support body for work, the end plate can be easily opened, and after the work is completed, it can be quickly locked again, ensuring the relative enclosure and safety of the working area.

[0020] In some specific embodiments, a second support body is placed on one side of the first support body, and a second end plate is hinged to both ends of the second support body. The second end plate can be fixedly connected to one end of the first support body, and the first end plate can be fixedly connected to one end of the second support body. A connecting pedal is laid on the inner bottom of the first end plate and the second end plate to further connect the second support body and the first support body for use.

[0021] A second support body is placed on one side of the first support body. Both ends of the second support body are hinged with second end plates, which can be fixedly connected to one end of the first support body, and vice versa. Connecting treads are laid on the inner bottom of the first and second end plates to further connect the second and first support bodies. This design allows for flexible expansion of the scaffolding's usable area and working range according to actual work needs, making it suitable for larger-scale construction tasks and improving the scaffolding's versatility and practicality.

[0022] In some specific implementations, both the first telescopic rod and the second telescopic rod are manually operated telescopic rods;

[0023] Both the first and second telescopic poles are manually operated. Manual telescopic poles are low-cost, easy to operate, and allow construction workers to easily control the opening angle of the side panels and the protective height of the guardrails without the need for complex power equipment. This meets the needs for adjusting the scaffolding structure in different construction scenarios and also facilitates maintenance and upkeep.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. This utility model allows for manual adjustment of the second telescopic rod, enabling the height of the protective rod to be freely adjusted according to the actual working height requirements, thereby changing the overall working height of the scaffold. This breaks the limitations of the traditional fixed height of scaffold and can adapt to different working tasks at different heights in semiconductor workshops, such as equipment installation and line maintenance, greatly improving the applicability of the scaffold.

[0026] 2. The operating platform is equipped with guardrails, and the side panels can be opened to a 45-degree angle, which effectively prevents tools or other items from falling to the ground, reduces the safety hazards caused by falling objects from heights, and provides a safer operating environment for workers to work at heights;

[0027] 3. The support frame with folding outriggers snapped at the bottom allows the adjustable outriggers to lie close to the ground, increasing the overall support area of ​​the equipment and improving its stability. Simultaneously, the folding section uses heavy-duty hinges for fixation, which is safer than traditional connection methods, making the scaffolding more robust and stable during use and reducing the risk of accidents caused by structural instability.

[0028] 4. The first and second casters at the bottom of the scaffolding facilitate easy movement and transportation within the workshop, saving time and effort. Furthermore, the foldable design of each part of the scaffolding allows for quick storage after use, reducing storage space requirements, making it easier to store, and improving space utilization.

[0029] 5. By connecting the second support body to the first support body and laying connecting treads between the first end plate and the second end plate, a larger working platform can be quickly built to meet the needs of different scales of operations, improve work efficiency, and reduce the time and labor costs of building complex and large scaffolding.
