Description

Technical Field

[0001] This utility model relates to the field of construction scaffolding technology, specifically a liftable construction scaffolding for building engineering. Background Technology

[0002] Scaffolding is an essential construction device on various construction sites, especially for high-rise buildings and large-scale projects such as municipal engineering. Scaffolding is a working platform erected to ensure the smooth progress of each construction process. The main body of the scaffolding is a frame structure, which facilitates the standing of construction workers. Scaffolding is mainly used for exterior walls, interior decoration, or in areas with high ceilings where direct construction is not feasible.

[0003] Chinese patent CN202321663198.2 discloses "A Construction Frame for Engineering Buildings" (publication number CN220267166U). This device includes a base, a servo motor, a construction enclosure, and a sliding rod; a moving component, in which symmetrical grooves are provided on the front and rear sides of the base, and the moving component is disposed within the grooves, allowing it to move left and right along the grooves; a driving component, located on both sides of the servo motor, which can drive the moving component to move inward or outward simultaneously; and a damping spring, located between the bottom surface of the sliding rod and the top surface of the base, which reduces vibrations caused by other structures. However, this device has some drawbacks: during use, workers and construction tools are supported by the construction frame, which exacerbates wear on the first lead screw thread, making it prone to stripping and posing a safety hazard during use. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a liftable construction scaffold for building engineering. When in use, this device can fix the raised construction platform, share the pressure borne by the threads, and reduce the wear rate of the threads.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liftable construction scaffold, comprising a construction platform, a construction enclosure fixedly connected to the construction platform, and a lifting mechanism for raising and lowering the construction platform. The construction enclosure is slidably connected to a support column, and a safety pin is inserted through the construction enclosure. A positioning hole matching the safety pin is opened on the support column, and the support column is fixedly connected to a base.

[0006] With the above structural design, after the construction platform is raised to the predetermined height, the construction platform is fixed with safety pins, which can share the pressure borne by the lifting mechanism and reduce the wear of the lifting mechanism parts.

[0007] Preferably, the safety pin is L-shaped, with its long side passing through the construction enclosure from the inside out, and a blocking block fixedly connected to its short side.

[0008] The above structural design ensures that the short side of the safety pin does not adhere to the construction fence, making it easier to pull out the safety pin.

[0009] Preferably, the lifting mechanism includes a connecting block symmetrically fixedly connected to the outer wall of the construction enclosure, a threaded rod threaded through the connecting block, a first synchronous pulley fastened to the lower end of the threaded rod, a second synchronous pulley rotatably connected to the base, a synchronous belt jointly fitted on the first and second synchronous pulleys, and a power component drivingly connected to the second synchronous pulley, wherein the threaded rod is rotatably connected to the base.

[0010] With the above structural design, the synchronous belt drives the two threaded rods to rotate simultaneously, which can save lifting energy and make the system more stable and secure.

[0011] Preferably, the power assembly includes a drive motor that is connected to the second synchronous belt pulley and an external power supply that is electrically connected to the drive motor. Both the drive motor and the external power supply are fixedly connected to the base.

[0012] The above structural design, using a motor drive, saves more time and effort, and reduces the workload of staff.

[0013] Preferably, the power assembly includes a driven bevel gear fixed coaxially with the second synchronous belt pulley, a driving bevel gear meshing with the driven bevel gear, a drive shaft fixedly connected to the driving bevel gear, and a handle fixedly connected to the drive shaft. The drive shaft is actively connected to a shaft seat, and the shaft seat is fixedly connected to a base.

[0014] The above structural design, coupled with manual drive, reduces production costs.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) When in use, this device can fix the raised construction platform, share the pressure of the thread, reduce the wear rate of the thread, prevent the thread rod from stripping, and also play a certain protective role.

[0017] 2) This device can drive two threaded rods simultaneously, which can save lifting energy and make it more stable and secure. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the structure of the present invention from the left view; Detailed Implementation

[0020] Example 1:

[0021] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a liftable construction scaffold for building engineering, including a construction platform 1, a construction enclosure 2 fixedly connected to the construction platform 1, and a lifting mechanism for lifting the construction platform 1. The construction enclosure 2 is slidably connected to a support column 3, and a safety pin 4 is inserted through the construction enclosure 2. The support column 3 has a positioning hole matching the safety pin 4, and the support column 3 is fixedly connected to a base 5.

[0022] The construction platform 1 is a square plate, and the construction enclosure 2 is fixedly connected to the four sides of the construction platform 1.

[0023] The safety pin 4 is L-shaped, and its long side passes through the construction enclosure 2 from the inside to the outside. A blocking block 41 is fixedly connected to the short side of the safety pin 4.

[0024] The lifting mechanism includes a connecting block 61 symmetrically fixedly connected to the outer wall of the construction enclosure 2, a threaded rod 62 threaded through the connecting block 61, a first synchronous pulley 63 fastened to the lower end of the threaded rod 62, a second synchronous pulley 64 rotatably connected to the base 5, a synchronous belt 65 jointly fitted on the first synchronous pulley 63 and the second synchronous pulley 64, and a power component that is driven by the second synchronous pulley 64. The threaded rod 62 is rotatably connected to the base 5.

[0025] Please see Figure 1 The upper end of the support column 3 is fixedly connected to the crossbeam 31, and the upper end of the threaded rod 62 is rotatably connected to the crossbeam 31 to increase the stability between the support columns 3.

[0026] The base 5 is fixedly connected to the movable wheel 9, with four movable wheels fixedly connected at the four corners of the base 5. The movable wheel is set below the position of the first synchronous belt pulley 63 on the base 5 to better support the threaded rod.

[0027] The power assembly includes a drive motor 71 that is connected to the second synchronous pulley 64 and an external power supply 72 that is electrically connected to the drive motor 71. Both the drive motor 71 and the external power supply 72 are fixedly connected to the base 5.

[0028] When using this device, the first step is to raise the construction platform 1. First, the operator starts the drive motor 71, and the second synchronous pulley 64, which is connected to the drive motor 71, rotates. Through the synchronous belt 65, the first synchronous pulley 63 rotates, which drives the threaded rod 62 to rotate. As the threaded rod 62 rotates, the connecting block 61, which is threadedly connected to the threaded rod 62, rises, thereby raising the construction platform 1.

[0029] The second step is to use the safety pin 4 to fix the construction platform after it is raised to the predetermined height by inserting it into the positioning hole on the support column 3, so as to share the pressure borne by the threaded rod 62.
