Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding, and particularly to a position stabilizing clamping device for a scaffolding used in building construction. Background Art

[0002] During the building construction process, a scaffolding is an indispensable temporary working platform for supporting workers and materials to ensure the safe progress of high-altitude operations.

[0003] However, traditional scaffolding has high requirements for the ground flatness. On uneven ground, it cannot provide sufficient supporting force, easily causing the scaffolding to tilt or even collapse, resulting in safety hazards. Although some height-adjustable scaffolding can adapt to different ground heights, the adjustment process is cumbersome, and each adjustment takes a lot of time and effort, reducing the construction efficiency.

[0004] Therefore, in construction sites with complex terrains or uneven ground, such as mountainous areas and old urban renovation projects, how to ensure the stability, safety, and adjustment convenience of the scaffolding has become an important issue. For this reason, the present invention provides a position stabilizing clamping device for a scaffolding used in building construction. Summary of the Invention

[0005] In order to overcome the drawback that traditional scaffolding cannot be quickly adjusted to adapt to construction sites with complex terrains or uneven ground, the present invention provides a position stabilizing clamping device for a scaffolding used in building construction.

[0006] A position stabilizing clamping device for a scaffolding used in building construction includes a connecting pipe. The connecting pipe is slidably connected with a support frame in the up and down direction. The connecting pipe is threadedly connected with a fastening bolt. The connecting pipe is fixedly connected with a fixed tooth array arranged in a ring. The support frame is slidably connected with a sliding tooth array arranged in a ring. The sliding teeth and the fixed teeth correspond to each other one by one. The support frame is provided with a pushing component for pushing the sliding teeth to move towards the corresponding fixed teeth when the support frame touches the ground, so that the sliding teeth and the corresponding fixed teeth are engaged with each other.

[0007] In one embodiment, the pushing component includes a pressing block corresponding to the sliding tooth. The pressing block is rotatably connected with the support frame. The pressing block is movably connected with the corresponding sliding tooth. A protrusion is arranged on the upper part of the pressing block. The support frame is slidably connected with a locking frame in the up and down direction. When the locking frame slides down relative to the support frame, it contacts the protrusion of the pressing block. When the support frame touches the ground, the locking frame squeezes the pressing block to swing. A spring is fixedly connected between the pressing block and the support frame.

[0008] In one embodiment, it further includes a first push rod arranged in a circumferential array. The first push rod is fixedly connected to the locking frame and is slidably connected to the support frame.

[0009] In one embodiment, it further includes fixing blocks distributed circumferentially. The fixing blocks are fixedly connected to one side of the support frame near the bottom. The first push rod is rotatably connected with a connecting rod. The fixing blocks are rotatably connected with a rotating frame. The connecting rods correspond to the rotating frames one by one, and the connecting rod is rotatably connected with the corresponding rotating frame.

[0010] In one embodiment, it further includes guide blocks corresponding to the fixing blocks. The guide blocks are fixedly connected to the corresponding fixing blocks. The rotating frame is slidably connected with a second push rod. The guide blocks are used to push the second push rod to slide. The rotating frame is rotatably connected with opening and closing frames symmetrically distributed along the rotating frame. The opening and closing frames are fixedly connected with arc-shaped frames. The second push rod is used to push the rotation of the adjacent arc-shaped frames.

[0011] In one embodiment, the guide block is provided with a guiding groove, and the second push rod is slidably connected with the guiding groove of the adjacent guide block.

[0012] In one embodiment, a movable groove is formed on one side of the second push rod close to the adjacent arc-shaped frame, and the arc-shaped frame is movably connected with the movable groove of the adjacent second push rod.

[0013] In one embodiment, it further includes a sponge pad sleeved on the outer wall of the locking frame, and a rubber pad is fixedly connected to the bottom of the support frame.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] Through the coordinated work of the locking frame, the support frame and the pressing block, the present invention enables the support frame to automatically adjust its position according to the ground height and contact the ground, realizing the function of adapting to the ground and ensuring that the scaffold can maintain stability on any terrain.

[0016] By the locking frame squeezing the pressing block to swing towards the compression spring, the sliding cogs are engaged into the fixed cogs, which not only fixes the position of the support frame but also applies force to lock the locking frame itself, preventing it from moving easily, thereby ensuring the stability of the entire system.

[0017] By the rotating frame rotating downward by ninety degrees around the fixing block to contact the ground, the supporting area is increased, the supporting stability is further improved, and the risk of tipping is reduced.

[0018] In the present invention, the opening and closing frame is driven by the rotating frame to open and contact the ground, significantly increasing the number and distribution range of ground contact points, and greatly enhancing the anti-tipping ability, especially on the low-lying side of the terrain.

[0019] In the present invention, by simply pushing the locking frame down to the bottom and pulling it up to the bottom, one-key adjustment and one-key reset of all components can be achieved. Moreover, by disassembling and installing the fastening bolts, the device can be easily disassembled and assembled, greatly simplifying the operation steps, facilitating disassembly and assembly, saving time and effort, thus quickly providing a safe working platform for construction workers and improving the on-site operation efficiency.

[0020] In the non-working state, components such as the rotating frame of the present invention are vertically retracted, reducing the occupied space, facilitating handling and storage. During work, they are unfolded to provide the maximum support effect, with a compact structure and being easy to carry.

[0021] The sponge pad of the present invention can protect the hand when pushing and pulling the locking frame. The rubber pad can deform adaptively to conform to the uneven ground surface, improving stability. It can also increase the friction with the ground, preventing the support frame from directly contacting the ground and slipping or being unstable. Description of the Drawings

Specific embodiments

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0034] Example 1: A device for stably clamping the position of a scaffolding used in building construction, as Figures 1-6 shown, includes a connecting pipe 101. A support frame 102 is slidably connected to the outside of the connecting pipe 101 in the up and down direction. A fastening bolt 103 is threadedly connected to the upper part of the connecting pipe 101. The connecting pipe 101 can be fixedly installed on any one of the legs of the scaffolding 1011 through the fastening bolt 103. Annularly arrayed fixed engaging teeth 104 are fixedly connected to the outer wall of the connecting pipe 101. Annularly arrayed sliding engaging teeth 105 are slidably connected to the upper part of the support frame 102. The sliding engaging teeth 105 correspond to the fixed engaging teeth 104 one by one. A pressing block 201 is rotatably connected to the upper part of the support frame 102. The pressing block 201 corresponds to the sliding engaging teeth 105 one by one. The pressing block 201 is movably connected to the corresponding sliding engaging tooth 105. A protrusion is provided on the upper part of the pressing block 201. A locking frame 202 is slidably connected to the outside of the support frame 102 in the up and down direction. When the locking frame 202 slides downward relative to the support frame 102, it contacts the protrusion of the pressing block 201. When the support frame 102 touches the ground, the locking frame 202 squeezes the pressing block 201 to swing. A spring 203 is fixedly connected between the pressing block 201 and the support frame 102. A circumferentially arrayed first push rod 204 is fixedly connected to the bottom of the locking frame 202. The first push rod 204 is slidably connected to the support frame 102.

[0035] On each leg of the scaffolding 1011, a connecting pipe 101 is installed through a fastening bolt 103. On the side with a low-lying terrain, the locking frame 202 is pushed downward. The locking frame 202 moves downward until it contacts the protrusion of the pressing block 201. The locking frame 202 pushes the pressing block 201 to move downward synchronously, thereby driving the support frame 102 to move downward synchronously along the connecting pipe 101, making the support frame 102 contact the ground. Then, the locking frame 202 is continuously pushed downward. Since the support frame 102 cannot move downward after touching the ground, the pressing block 201 cannot move downward either. Therefore, when the locking frame 202 is continuously pushed downward, the locking frame 202 moves downward relative to the support frame 102 and the pressing block 201, so that the locking frame 202 squeezes the pressing block 201 to swing toward the side of the compression spring 203, causing the pressing block 201 to push the sliding tooth 105 to engage with the fixed tooth 104, fixing the support frame 102. At the same time, the pressing block 201 can also apply a force to lock the locking frame 202 to prevent the locking frame 202 from moving easily. In this way, on uneven ground, the scaffolding 1011 can also be placed stably, avoiding the instability of the scaffolding 1011 caused by uneven terrain, improving the support stability of the scaffolding 1011, and thus improving the safety of the operation.

[0036] After use, the locking frame 202 is pulled upward. The locking frame 202 moves upward until it disengages from the protrusion of the pressing block 201. The spring 203 resets to drive the pressing block 201 to swing back in the reverse direction. The pressing block 201 pulls the sliding tooth 105 to disengage from the fixed tooth 104, releasing the fixation of the support frame 102. Then, the support frame 102 is pushed upward to reset. Finally, the fastening bolt 103 is unscrewed, and the device is removed from the scaffolding 1011, which is convenient for disassembly, assembly, and carrying.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figure 7 and Figure 8 shown, it further includes circumferentially distributed fixing blocks 301. The fixing blocks 301 are fixedly connected to the side of the support frame 102 near the bottom. The bottom end of the first push rod 204 is rotatably connected to a connecting rod 302. A rotating frame 303 is rotatably connected to the fixing block 301. The connecting rods 302 correspond to the rotating frames 303 one by one. The connecting rod 302 is rotatably connected to the corresponding rotating frame 303. After the support frame 102 touches the ground, the first push rod 204 pushes the rotating frame 303 to rotate downward by ninety degrees around the fixing block 301 through the connecting rod 302 until it contacts the ground.

[0038] When the locking frame 202 and the support frame 102 move downward synchronously, the first push rod 204, the fixed block 301, the connecting rod 302 and the rotating frame 303 move downward synchronously as a whole. When the support frame 102 touches the ground, the fixed block 301 descends to the lowest position. When the locking frame 202 moves downward relative to the support frame 102, the locking frame 202 drives the first push rod 204 to continue moving downward. The first push rod 204 pushes the rotating frame 303 to rotate downward by 90 degrees around the fixed block 301 until it contacts the ground, increasing the supporting area, thereby further improving the supporting stability of the scaffolding 1011.

[0039] When pulling the locking frame 202 upward, the locking frame 202 first drives the first push rod 204 to move upward relative to the support frame 102. The first push rod 204 pulls the rotating frame 303 to rotate upward by 90 degrees around the fixed block 301 until it is vertically retracted. Subsequently, continue to push the locking frame 202 upward. The locking frame 202 drives the connecting rod 302 to move upward through the first push rod 204, thereby pulling the rotating frame 303 to move upward. The rotating frame 303 pulls the support frame 102 to move upward and reset through the fixed block 301. In this way, there is no need to push the support frame 102 upward to reset anymore. Just pull the locking frame 202 upward to the end directly to reset.

[0040] As Figure 8 and Figure 9 shown, it further includes a guide block 401 corresponding to the fixed block 301. The guide block 401 is fixedly connected to the corresponding fixed block 301. The guide block 401 is provided with a guiding groove. A second push rod 402 is slidably connected to the rotating frame 303. The second push rod 402 is slidably connected to the guiding groove of the adjacent guide block 401. When the rotating frame 303 rotates downward around the fixed block 301, the guiding groove of the guide block 401 pushes the second push rod 402 to slide. The rotating frame 303 is rotatably connected with opening and closing frames 404 symmetrically distributed along the rotating frame 303. The opening and closing frames 404 are fixedly connected with arc-shaped frames 403. An activity groove is formed on one side of the second push rod 402 close to the adjacent arc-shaped frame 403. The arc-shaped frame 403 is movably connected with the activity groove of the adjacent second push rod 402. When the second push rod 402 slides, it pushes the opening and closing frames 404 to swing and open through the activity groove.

[0041] During the process of the rotating frame 303 rotating downward by 90 degrees around the fixed block 301 until it contacts the ground, the rotating frame 303 drives the second push rod 402, the arc-shaped frame 403 and the opening and closing frame 404 to rotate downward by 90 degrees as a whole, so that the opening and closing frame 404 also contacts the ground. At the same time, under the action of the guiding groove of the guiding block 401, the second push rod 402 slides relative to the rotating frame 303 toward the side close to the opening and closing frame 404. The second push rod 402 pushes the opening and closing frame 404 to swing and open through the movable groove, increasing the force-bearing area, thereby improving the stability of the support feet of the scaffolding 1011 on the low-lying side and preventing the scaffolding 1011 from tipping over.

[0042] During the process of the rotating frame 303 rotating upward by 90 degrees around the fixed block 301 until it is vertically retracted, the rotating frame 303 drives the second push rod 402, the arc-shaped frame 403 and the opening and closing frame 404 to rotate upward by 90 degrees as a whole. At the same time, under the action of the guiding groove of the guiding block 401, the second push rod 402 slides relative to the rotating frame 303 toward the side away from the opening and closing frame 404. The second push rod 402 pulls the opening and closing frame 404 to swing and close in the reverse direction through the movable groove.

[0043] Embodiment 3: On the basis of Embodiment 2, as Figure 10 shown, it further includes a sponge pad 501. The sponge pad 501 is sleeved on the outer wall of the locking frame 202. The sponge pad 501 can protect the hand when pushing and pulling the locking frame 202. A rubber pad 502 is fixedly connected to the bottom of the support frame 102. The rubber pad 502 can deform adaptively, so as to adapt to the uneven ground surface, improve the stability, and can also increase the friction force in contact with the ground, preventing the support frame 102 from slipping or being unstable due to direct contact with the ground.

[0044] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
