Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and more specifically, to an engineering construction scaffold. Background Technology

[0002] Construction scaffolding refers to various supports erected on construction sites to facilitate worker operations and solve vertical and horizontal transportation issues. It is a common term in the construction industry, referring to the supports used on construction sites for exterior walls, interior decoration, or high-ceilinged areas where direct construction is not possible. It mainly serves to facilitate workers' up-and-down operations, external safety netting, and the installation of components at heights, playing a very important role in the construction field.

[0003] Patent CN214462382U discloses a construction scaffold, including a first frame, a first diagonal brace, a connecting sleeve, a rotating shaft, and a second frame. The first frame is symmetrically connected to two first ring hoops, each with a first diagonal brace fixedly connected to one side. The first ring hoops, in conjunction with second ring hoops, allow the first and second diagonal braces to rotate on the first and second frames. Simultaneously, the connecting sleeve and rotating shaft allow for rotation of both the first and second frames, enabling the overall folding of the scaffold. This significantly reduces the time required for traditional scaffold assembly and disassembly, improving work efficiency. An extension rod, used in conjunction with a third horizontal bar, allows for height adjustment of the scaffold, avoiding secondary erection and saving manpower and resources.

[0004] Although the device has many beneficial effects, the following problems still exist: Although the construction scaffold can be adjusted in height, the workspace provided to the workers during use is fixed. The fixed workspace may not meet the needs of different work tasks. Some construction tasks require a larger operating space, but the fixed-size scaffold may limit the movement and operating range of the workers. Sometimes, when encountering areas that cannot be reached, workers need to get off the scaffold and make adjustments, which reduces work efficiency. Utility Model Content

Detailed Implementation

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-6 , the present invention provides a technical solution:

[0030] An engineering construction scaffold, including two support rods 1, a plurality of equally spaced cross bars 2 are fixedly connected between the two support rods 1, a bottom plate 4 is fixedly connected between the two support rods 1, two symmetrically distributed moving plates 5 are arranged above the bottom plate 4, and further includes:

[0031] Two sets of stretching components, which are symmetrically distributed on the outer surface of the bottom plate 4 and are used to drive the corresponding moving plates 5 to move;

[0032] An opening and closing type protection component, which is located between the two support rods 1 and is used to protect the staff. The construction scaffold uses two support rods 1 as the main vertical support structures, and they are reinforced by a plurality of equally spaced cross bars 2 to ensure the overall stability and bearing capacity. The operator can climb through the plurality of cross bars 2 at the bottom of the support rods 1.

[0033] Furthermore, the stretching component includes guide rails 12, sliders 13, belts 14, mounting frames 15, first belt pulleys 16 and socket rings 21. The bottom plate 4 is arranged in a "convex" shape. Two guide rails 12 are fixedly connected to the top of the bottom plate 4. Two sliders 13 are slidably connected to the top of the two guide rails 12. The four sliders 13 are fixedly connected to the corresponding moving plates 5. Two mounting frames 15 are fixedly connected to the outer surface of the bottom plate 4 and the outer surface of the protruding part of the bottom plate 4. The inner parts of the four mounting frames 15 are rotatably connected with first belt pulleys 16. Belts 14 are sleeved between the two first belt pulleys 16 on the same side. Socket rings 21 are fixedly sleeved on the outer surfaces of the two belts 14. The two socket rings 21 are fixedly connected to the corresponding moving plates 5. These two second belt pulleys 18 are respectively sleeved on the inner sides of the two belts 14 and form a closed loop with the other two first belt pulleys 16, so as to drive the belts 14 to rotate in a cycle. The socket rings 21 are fixedly sleeved on the outer surface of the belts 14 and the socket rings 21 are fixedly connected to the moving plates 5. Therefore, when the belts 14 rotate, they will drive the socket rings 21 and the moving plates 5 fixed thereto to move along the guide rails 12. The design of the guide rails 12 and the sliders 13 ensures that the moving plates 5 can move smoothly and accurately to both sides of the bottom plate 4.

[0034] Furthermore, the stretching component further includes a driving motor 17 and a second pulley 18. Two bearing seats are fixedly connected to the bottom of the bottom plate 4. The outer surfaces of the two bearing seats close to each other are rotatably connected to the second pulley 18. A connecting shaft is fixedly connected between the two second pulleys 18. A driving motor 17 is fixedly installed on the outer surface of one of the bearing seats. The output end of the driving motor 17 is fixedly connected to the adjacent second pulley 18. The two second pulleys 18 are sleeved with the corresponding belts 14. When the driving motor 17 is started, the output end of the driving motor 17 drives one second pulley 18 to rotate. Since the two second pulleys 18 are fixedly connected by a connecting shaft, the other second pulley 18 will also rotate synchronously.

[0035] Furthermore, four symmetrically distributed pressure wheels 19 are rotatably connected to the bottom of the bottom plate or base plate 4. The four pressure wheels 19 are in rolling connection with the corresponding belts 14. Four pressure wheels 19 are also rotatably connected to the bottom of the bottom plate 4, and they are in rolling contact with the belts 14, reducing the friction and wear of the belts 14 during movement.

[0036] Furthermore, the opening and closing type protection component includes railings 6, universal ball heads 8, clamping blocks 11 and clamping blocks 20. Universal ball heads 8 are rotatably connected to the outer surfaces on both sides of the support rod 1. Railings 6 are fixedly connected to the outer surfaces of the two universal ball heads 8. The two railings 6 are located at the uppermost part of the multiple cross bars 2. Clamping blocks 20 are fixedly connected to the ends of the two railings 6. Clamping blocks 11 are fixedly connected to the outer surfaces on both sides of the other support rod 1. The two clamping blocks 11 are both arranged in an L-shaped structure. The two clamping blocks 20 are clamped with the corresponding clamping blocks 11. The railings 6 are rotatably connected to the support rod 1 through the universal ball heads 8 and can be opened and closed flexibly. Clamping blocks 20 are fixed to the ends of the railings 6 and can be clamped with the clamping blocks 11 on the other support rod 1 to fix the position of the railings 6, thereby protecting the operators located on the bottom plate 4.

[0037] Furthermore, the two support rods 1 are both arranged in a "冃" - shaped structure. Reinforcement rods 3 are fixedly connected to the outer surfaces of the two support rods 1. The two reinforcement rods 3 are both arranged in an inclined structure. A reinforcement plate 9 is fixedly connected between one of the reinforcement rods 3 and the support rod 1. A PLC controller 10 is fixedly installed on the outer surface of the reinforcement plate 9. The driving motor 17 is wirelessly connected to the PLC controller 10. The PLC controller 10 can selectively control the start of the driving motor 17 on one side or both sides.

[0038] Furthermore, universal wheels 7 are fixedly installed at the bottoms on the same side of the two support rods 1. Installing the universal wheels 7 makes it convenient to move and adjust the position of the entire construction scaffold on the ground.

[0039] Working Principle: When workers need to use this construction scaffold, the scaffold consists of two support rods 1 as the main vertical support structure, reinforced by multiple equidistant horizontal bars 2 to ensure overall stability and load-bearing capacity. Operators can climb using the horizontal bars 2. At the bottom of the support rods 1, casters 7 are installed, allowing the entire scaffold to be easily moved and its position adjusted on the ground. After the worker separates the locking block 11 from the clamping block 20 and enters the bottom plate 4, when the position of the moving plate 5 needs adjustment, the PLC controller 10 wirelessly connects to the drive motor 17, selectively controlling the start of one or both drive motors 17. The drive motor 17 starts, and its output drives a second pulley 18 to rotate. Since the two second pulleys 18 are fixedly connected by a connecting shaft, the other second pulley 18 will also rotate synchronously. These two second pulleys 18 are respectively fitted inside the two belts 14 and connected to the other two first pulleys 16. A closed loop is formed, which drives the belt 14 to rotate cyclically. A sleeve ring 21 is fixedly sleeved on the outer surface of the belt 14. The sleeve ring 21 is fixedly connected to the moving plate 5. Therefore, when the belt 14 rotates, it will drive the sleeve ring 21 and the moving plate 5 fixed thereto to move along the guide rail 12. The design of the guide rail 12 and the slider 13 ensures that the moving plate 5 can move smoothly and accurately to both sides of the base plate 4. In order to maintain the tension and stability of the belt 14, four pressure rollers 19 are also rotatably connected to the bottom of the base plate 4. They roll in contact with the belt 14, reducing the friction and wear of the belt 14 during the movement. In addition, the construction frame is also equipped with an openable and closable protective component to protect the safety of the workers. The railing 6 is rotatably connected to the support rod 1 through the universal ball joint 8, which can be flexibly opened and closed. The end of the railing 6 is fixed with a clamping block 20, which can be clamped with the clamping block 11 on another support rod 1 to fix the position of the railing 6, thereby protecting the operators on the base plate 4. The reinforcing rod 3 is set to enhance its stability.
