Description

Technical Field

[0001] This utility model relates to the field of engineering quality testing technology, and in particular to a safety and stability device for high-altitude operations. Background Technology

[0002] In the process of engineering quality inspection, aerial work platforms and suspended platforms are often used for high-altitude operations. However, the operating platform of the aerial work platform and the suspended platform can sway during high-altitude operations.

[0003] Taking the aerial work platform as an example, due to the limitation of the size of the construction elevator when moving between floors, only a small aerial work platform can be selected, which has poor balance and stability. The operating platform of the aerial work platform will shake for the following reasons: (1) According to the mechanical formula: δ=PL 3 / 3EI, the deformation is related to the cube of the height. At a height of 6 meters, the deformation is 216 times greater than at 1 meter and 8 times greater than at 3 meters. The higher the operating platform is raised, the greater the displacement. (2) The support feet of the small aerial work platform are too simple (the support clearance from the ground is reduced from 11cm to 2cm when it is raised). Even the extended support feet of the large aerial work platform can only prevent the whole vehicle from collapsing and cannot prevent the shaking of the top operating platform. (3) The scissor arm of the aerial work platform is a multi-mechanical structure. As the connecting structure wears down, the gap between the components becomes larger. The larger the gap, the greater the displacement of the platform.

[0004] The platform sway of the aerial work platform has the following effects on high-altitude operations: (1) For example, during the rebound operation of the beam, the platform sway makes it impossible to operate the rebound hammer smoothly, affecting the accuracy of the data; (2) For example, according to on-site work experience, picking up tools at a height of 6 meters will also cause the platform to sway significantly, causing fear among personnel and making it impossible to perform large movements, greatly reducing work efficiency; (3) According to the safety management regulations of the aerial work platform, personnel on the platform should wear safety belts and should not fasten the safety belts to the vehicle. However, in actual operation, it is difficult to find a place to fasten the safety belts except for the platform of the vehicle. In addition, the safety awareness of workers is generally low, which leads to failure to implement the regulations and poses a great accident hazard.

[0005] In response to the swaying problems of the aerial work platform and the suspended platform (e.g., the stronger the wind, the easier it is to sway), there is an urgent need to design and manufacture a lightweight and practical safety and stabilizing device to fix the operating platform of the aerial work platform or the suspended platform.

The stabilizing structure is a C-type clamping assembly 3 for clamping onto beam and column members. The adjusting arm 2 is installed between the clamping assembly 1 and the C-type clamping assembly 3 and the distance between them can be adjusted. The clamping assembly 1, the adjusting arm 2, the C-type clamping assembly 3, and the adjusting arm 2 are combined for use in beam and column member operation scenarios.

[0030] like Figure 1 and Figure 2 As shown, the clamping assembly 1 includes a first clamp 1-1 in the shape of a "U", a first locking screw 1-2 threaded to one side of the first clamp 1-1, and a first clamping end cap 1-3 disposed at one end of the first locking screw 1-2 located inside the first clamp 1-1. The first clamp 1-1 has a mounting hole in the middle (not shown in the figure). The first clamping end cap 1-3 is first fitted onto the end of the first locking screw 1-2 and then tightened and fixed by screws.

[0031] like Figures 1 to 3 As shown, the cross-section of the adjusting arm 2 is U-shaped. One end of the adjusting arm 2 is provided with a connecting hole 2-1, and the other end of the adjusting arm 2 is provided with a waist-shaped adjusting hole 2-2 extending along its length. A connecting wedge 2-3 is embedded in the end of the adjusting arm 2 near the connecting hole 2-1. The connecting hole 2-1 and the connecting wedge 2-3 of the adjusting arm 2 are connected by a first bolt and nut 2-4. The middle part of the first clip 1-1 abuts against the connecting wedge 2-3. A connecting screw 2-5 is provided between the mounting hole of the first clip 1-1 and the connecting wedge 2-3.

A through hole is provided in the middle of the second clip 3-1, and the through hole of the second clip 3-1 and the waist-shaped adjustment hole 2-2 of the adjusting arm 2 are fixed together by a second bolt and nut 2-6.

[0033] Implementation Results: When stabilizing beam and column components in a work scenario, the adjusting arm 2 is installed between the clamping assembly 1 and the C-type clamping assembly 3. The clamping assembly 1 is used to fix the platform or basket of the aerial work platform, and the C-type clamping assembly 3 is used to clamp the beam and column components. During the stabilization process, the distance between the two is adjusted by the adjusting arm 2 to stabilize the platform or basket of the aerial work platform. Ultimately, the platform or basket of the aerial work platform can be fixed, improving safety during construction and ensuring the accuracy of test data.

[0034] When fixing the clamping assembly 1 to the operating platform of the aerial work platform or the suspended platform, firstly, the first clip 1-1 is placed on the guardrail post of the operating platform or the suspended platform, and then tightened by the first locking screw 1-2, which drives the first clamping end cap 1-3 to clamp and fix on the guardrail post. The C-type clip assembly 3 is installed at the waist-shaped adjustment hole 2-2 to adjust the installation position, thereby adjusting the distance between the C-type clip assembly 3 and the clamping assembly 1. At the same time, the first clip 1-1 can rotate around the connecting screw 2-5 to facilitate adjustment of the relative angle between the clamping assembly 1 and the C-type clip assembly 3, facilitating installation and fixation.

The stabilizing structure is a suction cup assembly 4 for adhering to smooth surfaces. The adjusting arm 2 is installed between the clamping assembly 1 and the suction cup assembly 4 to adjust the distance between them. The clamping assembly 1, adjusting arm 2, and suction cup assembly 4 are combined for use in work scenarios on smooth surfaces.

[0036] like Figures 3 to 5 As shown, the clamping assembly 1 includes a first clamp 1-1 in the shape of a "U", a first locking screw 1-2 threaded to one side of the first clamp 1-1, and a first clamping end cap 1-3 disposed at one end of the first locking screw 1-2 located inside the first clamp 1-1. The first clamp 1-1 has a mounting hole in the middle. The first clamping end cap 1-3 is first fitted onto the end of the first locking screw 1-2 and then tightened and fixed by screws.

[0037] like Figures 3 to 5 As shown, the cross-section of the adjusting arm 2 is U-shaped. One end of the adjusting arm 2 is provided with a connecting hole 2-1, and the other end of the adjusting arm 2 is provided with a waist-shaped adjusting hole 2-2 extending along its length. The middle part of the first clip 1-1 abuts against the outer surface of the adjusting arm 2 near the waist-shaped adjusting hole 2-2. The mounting hole of the first clip 1-1 and the waist-shaped adjusting hole 2-2 of the adjusting arm 2 are fixed together by a third bolt and nut 2-7. The position and angle of the first clip 1-1 can be adjusted during installation. The suction cup assembly 4 is provided at the end of the adjusting arm 2 near the connecting hole 2-1.

[0038] like Figures 3 to 5 As shown, the suction cup assembly 4 includes a connecting bracket 4-1 and two suction cups 4-2 respectively disposed on both sides of the connecting bracket 4-1. The upper surface of the adjusting arm 2 near the connecting hole 2-1 is provided with a third clip 2-8 for the connecting bracket 4-1 to be inserted. The third clip 2-8 and the connecting hole 2-1 of the adjusting arm 2 are fixed together by a fourth bolt and nut 2-9. A third locking screw 2-10 is provided on the side of the third clip 2-8 near the first clip 1-1. A third clamping end cap 2-11 for pressing against the connecting bracket 4-1 is provided at the end of the third locking screw 2-10 located inside the third clip 2-8.

[0039] Implementation effect: When stabilizing work scenarios involving smooth surfaces such as steel and aluminum profiles, glass, and wood, the suction cup assembly 4 is used to adhere to the smooth surface, and the distance between the two is adjusted by the adjusting arm 2 during the fixing process; ultimately, the operating platform or basket of the aerial work platform can be fixed, improving the safety of the construction process and ensuring the accuracy of the test data.

[0040] The first clip 1-1 can be adjusted in position during the installation of the oblong adjustment hole 2-2 on the adjusting arm 2, thereby adjusting the distance between the C-type clip assembly 3 and the suction cup assembly 4. Simultaneously, the first clip 1-1 can also be adjusted in angle during the installation of the oblong adjustment hole 2-2 on the adjusting arm 2, facilitating the adjustment of the relative angle between the C-type clip assembly 3 and the suction cup assembly 4, thus simplifying installation and fixation. The suction cup assembly 4 includes two suction cups 4-2 to ensure stability during suction fixation. The connecting bracket 4-1 of the suction cup assembly 4 is embedded in the third clip 2-8, and during the tightening of the third locking screw 2-10, the connecting bracket 4-1 is clamped and fixed by the third clamping end cap 2-11, thereby achieving the installation and fixation of the suction cup assembly 4.

[0041] Example 3: A safety and stabilization device for high-altitude operations, such as Figures 4 to 6 As shown, the difference from Embodiment 2 lies in the different stabilizing structure. The stabilizing structure is only applicable to the use of the aerial work platform. The stabilizing structure is a rubber head assembly 5 used to press against the floor during the upward movement. The rubber head assembly includes a connecting rod 5-1 and two rubber support blocks 5-2 set at both ends of the connecting rod 5-1. The middle part of the connecting rod 5-1 is embedded in the third clip 2-8 and pressed and fixed by the third clamping end cap 2-11.

[0042] Implementation effect: In the case of a working environment where there is no direct fixation under the floor slab, by installing the stabilizing device vertically, the rubber support block 5-2 is pressed against the floor slab for support as the operating platform of the aerial work platform moves upward, thereby increasing the stability of the aerial work platform.

[0043] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
