Description

Technical Field

[0001] This utility model relates to the field of construction engineering equipment technology, and in particular to a construction engineering scaffold with anti-slip function. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] Portal scaffolding is a commonly used type of scaffolding. Its bottom is supported by casters with locking function. However, in scenarios with smooth ground, such as tiled floors or epoxy floor paint floors, slippage is likely to occur, posing a significant safety hazard to workers standing on the scaffolding. To address this issue, we propose a construction scaffolding with anti-slip function. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a construction scaffold with anti-slip function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction scaffold with anti-slip function includes a scaffold body, and a support component is provided at the lower end of the scaffold body;

[0007] The support assembly includes a connecting plate, with a caster wheel rotatably connected to the lower end of the connecting plate, and a sleeve fixedly connected to the connecting plate. A support rod is slidably connected inside the sleeve, and a placement plate is fixedly connected to the support rod. A lifting assembly is provided on the lower surface of the placement plate. An inner support frame is also fixedly connected to the lower end of the scaffold body, and an auxiliary wheel is provided on the lower surface of the inner support frame near the lifting assembly.

[0008] Preferably, the lifting assembly includes a diagonal rod rotatably connected to the inner support frame, a threaded sleeve rotatably connected to the diagonal rod, a rotating rod rotatably connected to the upper end of the threaded sleeve, a support plate rotatably connected to the upper end of the rotating rod, the support plate being fixedly connected to the lower surface of the placement plate, a vertical rod slidably connected to the inner support frame, and a threaded rod matching the threaded sleeve rotatably connected to the vertical rod.

[0009] Preferably, a friction plate is fixedly connected to the lower end of the support rod, and a push block is fixedly connected to the side of the support plate near the caster wheel.

[0010] Preferably, the caster wheel includes a turntable rotatably connected to the connecting plate, an inclined wheel frame is fixedly connected to the lower end of the turntable, a roller is rotatably connected to the wheel frame, and a brake block that cooperates with the push block is slidably connected to the wheel frame.

[0011] Preferably, the brake block includes an L-shaped plate that is slidably connected to the wheel frame, an arc-shaped plate is fixedly connected to the L-shaped plate, and a wedge-shaped block is fixedly connected to the side of the L-shaped plate away from the arc-shaped plate.

[0012] Preferably, the end of the threaded rod near the vertical rod is rotatably connected to a lever via a damping shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, by setting up a support component, allows heavy objects to be placed on the placement board. The lower end of the support rod abuts against the ground, increasing the friction between the scaffold and the ground and lowering the center of gravity of the entire scaffold, thereby improving the stability of the scaffold. At the same time, the support rod locks the casters, preventing them from rotating. Ultimately, this prevents the scaffold from slipping when used on relatively smooth ground, thus improving the safety of construction workers during operations.

[0015] This invention, by setting up a lifting component, can drive the placement plate upward, so that the support rod is lifted off the ground and the casters are no longer locked, making operation simpler. Furthermore, users can place construction tools and materials on the placement plate and use the entire scaffold as a handcart. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A construction scaffold with anti-slip function includes a scaffold body 1, and a support component is provided at the lower end of the scaffold body 1.

[0023] The scaffold body 1 is the frame scaffold excluding the bottom wheels;

[0024] The support assembly includes a connecting plate 2, and a universal wheel is rotatably connected to the lower end of the connecting plate 2. The universal wheel includes a turntable 16 rotatably connected to the connecting plate 2. An inclined wheel frame 17 is fixedly connected to the lower end of the turntable 16. A roller 18 is rotatably connected to the wheel frame 17. A brake block that cooperates with the push block 15 is also slidably connected to the wheel frame 17.

[0025] The turntable 16 is not located directly below the supporting leg of the scaffold body 1. The wheel frame 17 is tilted. When the user pushes the wheel frame 17, the wheel frame 17 will rotate to the side opposite to the direction of movement of the scaffold body 1. The brake block can be used to lock the roller 18.

[0026] A sleeve 3 is fixedly connected to the connecting plate 2. A support rod 4 is slidably connected inside the sleeve 3. The support rod 4 movably passes through both ends of the sleeve 3, and a placement plate 5 is fixedly connected to the support rod 4. A lifting assembly is provided on the lower surface of the placement plate 5. An inner support frame 6 is also fixedly connected to the lower end of the scaffold body 1. An auxiliary wheel 7 is provided on the surface of the inner support frame 6 near the lifting assembly.

[0027] In this design, the sleeve 3 is positioned near the caster wheel and above the connecting plate 2. The placement plate 5 is located at the top of multiple support rods 4. During actual use, construction workers first push the scaffold body 1 to the vicinity of the construction point. After ensuring the wheel frame 17 rotates to the side where the brake pads face the support rod 4, they control the lifting assembly to lower the placement plate 5. At this time, the support rods 4 also move downwards, thus bringing them against the ground and locking the roller 18 with the brake block. While fixing the roller 18, the support rods 4 increase the friction between the entire scaffold and the ground, ultimately achieving anti-slip properties. Based on this, on the ground... In relatively smooth environments, after the support rod 4 makes contact with the ground, additional weights can be placed on the placement plate 5 to increase the pressure between the support rod 4 and the ground, thereby increasing the friction between the lower end of the support rod 4 and the ground, further improving the protective effect of this type of scaffold. In addition, the placement plate 5 can also be used to place construction tools and materials. When it needs to be moved, the lifting component is used to move the placement plate 5 upward, so that the support plate 11 is separated from the ground and detached from the brake block. In this way, the entire scaffold can be used as a handcart, which is more convenient for construction workers to operate, while ensuring that the center of gravity of the scaffold is low and it is not easy to tip over when moving.

[0028] It should be noted that with the omnidirectional wheels in the above scheme, since the wheel frame 17 will rotate to the side opposite to the direction of movement of the scaffold body 1 when the user pushes the wheel frame 17, the position of the roller 18 can be adjusted before the lifting assembly lowers the placement plate 5.

[0029] Furthermore, the lifting assembly includes two inclined rods 8 rotatably connected to the inner support frame 6 via a rotating shaft. The inclined rods 8 are symmetrically arranged. A threaded sleeve 9 is rotatably connected to the inclined rod 8 via a rotating shaft. A rotating rod 10 is rotatably connected to the upper end of the threaded sleeve 9 via a rotating shaft. A support plate 11 is rotatably connected to the upper end of the rotating rod 10 via a rotating shaft. The support plate 11 is fixedly connected to the lower surface of the placement plate 5. A vertical rod 12 is vertically movably connected through the inner support frame 6. A threaded rod 13 matching the threaded sleeve 9 is rotatably connected to the vertical rod 12 to improve the stability of the threaded rod 13.

[0030] The threaded rod 13 is provided with left-hand threads and right-hand threads near the two threaded sleeves 9 respectively. When the user rotates the threaded rod 13, it drives the threaded sleeves 9 to move closer to each other or further away from each other, thereby driving the inclined rod 8 and the rotating rod 10 to rotate. After the inclined rod 8 and the rotating rod 10 rotate, they drive the support plate 11 to move up or down, thus meeting the requirement of the lifting assembly to drive the placement plate 5 to move up and down.

[0031] Furthermore, a friction plate 14 is fixedly connected to the lower end of the support rod 4, and a push block 15 is fixedly connected to the side of the support plate 11 near the universal wheel;

[0032] Friction plate 14 is provided to increase the friction area between support rod 4 and the ground, thereby increasing friction and improving anti-slip effect. Rubber anti-slip pad is provided on the lower surface of friction plate 14.

[0033] Furthermore, the brake block includes an L-shaped plate 19 that is slidably connected to the wheel frame 17, an arc-shaped plate 20 is fixedly connected to the L-shaped plate 19, and a wedge-shaped block 21 is fixedly connected to the side of the L-shaped plate 19 away from the arc-shaped plate 20.

[0034] In this design, the wedge block 21 is positioned close to the support rod 4. As the support rod 4 moves downward, the push block 15 abuts against the wedge block 21, causing the wedge block 21 and the L-shaped plate 19 to move towards the roller 18 until the arc plate 20 abuts against the roller 18. The friction between the arc plate 20 and the roller 18 is used to lock the roller 18. The arc plate 20 can also be replaced with a professional brake pad that provides better braking performance.

[0035] Furthermore, the threaded rod 13 is rotatably connected to a lever 22 at one end near the vertical rod 12 via a damping shaft;

[0036] The lever 22 can be rotated relative to the threaded rod 13 to a state parallel to or perpendicular to it. When the lever 22 is rotated to a state perpendicular to the threaded rod 13, the user can more easily rotate the threaded rod 13 by moving the lever 22, thereby adjusting the lifting component.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
