Detailed implementation manners

[0031] To make the purpose, technical solution and advantages of this technical solution clearer and more understandable, the following further details this technical solution in combination with specific implementation manners. It should be understood that these descriptions are exemplary and not intended to limit the scope of this technical solution.

[0032] Refer to Figures 1 to 8 , Figure 1 It is a schematic structural diagram of the whole high-altitude operation protection device; Figure 2 It is a schematic structural diagram of a partial structure of a high-altitude operation protection device; Figure 3 It is a schematic structural diagram of the movable guardrail of a high-altitude operation protection device; Figure 4 It is an exploded view of a partial structure of a high-altitude operation protection device; Figure 5Schematic diagram of the structure of the mounting column of a high-altitude work protection device; Figure 6 Enlarged view of the structure at part A of a high-altitude work protection device; Figure 7 Enlarged view of the structure at part B of a high-altitude work protection device; Figure 8 Enlarged view of the structure at part C of a high-altitude work protection device. A high-altitude work protection device includes: a base 1, a detachable fixed guardrail arranged above the base 1, a movable guardrail 5 sleeved outside the fixed guardrail and capable of moving up and down, and a telescopic cylinder 7 for driving the movable guardrail 5 to move up and down.

[0033] The utility model provides a technical solution: a high-altitude work protection device includes a base 1. The base 1 is a rectangular plate-like structure. Square mounting frames 11 are respectively welded at the four corners of the top of the base 1. Mounting columns 2 are respectively vertically arranged at the four corners of the base 1. The bottom end of the mounting column 2 is detachably mounted in the mounting frame 11.

[0034] The mounting column 2 is composed of a pillar 21 and a slide rail 22. The pillar 21 is a columnar structure with a square cross-section. The outer peripheral wall of the bottom end of the pillar 21 is in close contact with the inner peripheral wall of the mounting frame 11. Slide rails 22 extending in the same direction as the pillar 21 are respectively welded on the side walls around the pillar 21 and at the middle positions of the side walls. The length of the slide rail 22 is less than the height of the pillar 21 minus the depth of the mounting frame 12, and the top end of the slide rail 22 is flush with the top end of the pillar 21. A groove 221 with a T-shaped cross-section and a closed bottom end is formed on the slide rail 22.

[0035] A first guard plate 3 and a second guard plate 4 are respectively mounted between the four mounting columns 2 above the base 1. The mounting column 2, the first guard plate 3 and the second guard plate 4 form a rectangular fixed guardrail.

[0036] The first guard plate 3 is respectively mounted between the opposite slide rails 22 on the two mounting columns 2 on both long sides of the base 1. The first guard plate 3 is a rectangular plate-like structure. Sliders 31 are respectively fixed at the upper and lower ends on the left and right sides of the first guard plate 3. The shape of the slider 31 matches the shape of the groove 221.

[0037] The second guard plate 4 is respectively mounted between the opposite slide rails 22 on the two mounting columns 2 on both short sides of the base 1. The second guard plate 4 is a rectangular plate-like structure. Sliders 41 are respectively fixed at the upper and lower ends on the left and right sides of the second guard plate 4. The shape of the slider 41 matches the shape of the groove 221.

[0038] By installing the fixed guardrail on the top end of the base 1 in a splicing manner, the traditional integral working platform is changed into a detachable structure, which is not only convenient to carry but also reduces the transportation volume.

[0039] A protective cover 8 is also provided at the top of the installation column 2. A threaded hole is provided at the center of the top end of the support column 21. The protective cover 8 is fixedly installed at the top of the installation column 2 by screws, preventing potential safety hazards caused by the up-and-down movement of the first guard plate 3 and the second guard plate 4 after they are installed, due to the unclosed top end of the sliding groove 22.

[0040] A movable guardrail 5 that can move up and down is sleeved outside the fixed guardrail. The movable guardrail 5 includes a frame, which is composed of an upper fence 51, a lower fence 52, and four support columns 52. Both the upper fence 51 and the lower fence 52 are rectangular frame structures and are exactly the same in size and shape. At the four corners of the lower surface of the upper fence 51, they are fixedly connected to the four corners of the upper surface of the lower fence 52 through the support columns 53 one by one, making the overall shape of the frame a cuboid. A plurality of connecting columns 54 are distributed on the four sides of the frame to increase the overall safety of the movable guardrail 5. Vertically corresponding to the outer sliding rails 22 of the four installation columns 2 inside the frame, there are slide bars 55 with a T-shaped cross-section. The slide bars 55 match the grooves 221, and the slide bars 55 are slidably arranged in the grooves 221. The movable guardrail 5 drives the movable guardrail 5 to move up and down by sliding the slide bars 55 in the grooves 221.

[0041] On both sides of the two long sides of the base 1, side plates 6 are respectively fixedly connected. At the middle positions of the upper surfaces of the two side plates 6, a plurality of telescopic cylinders 7 are respectively fixedly installed. The number of telescopic cylinders 7 mentioned in this embodiment is three. At the positions corresponding to the telescopic cylinders 7 on both long sides of the movable guardrail 5, there are fixed connection plates 56. The movable ends of the telescopic cylinders 7 are fixedly connected to the lower surfaces of the fixed connection plates 56. By pushing the fixed connection plates 56 upward through the telescopic cylinders 7, the overall movable guardrail 5 is driven to move upward. And through the telescopic degree of the telescopic cylinders 7, the moving height of the movable guardrail 5 can be controlled, and thus the height of the movable guardrail 5 can be adjusted according to the height of the operators, protecting the safety of the operators.

[0042] Working principle: When using this working platform, first fixedly install the mounting column 2 in the mounting frame 11 to ensure that the mounting column 2 will not loosen. Then, after installing the first guard plate 3 and the second guard plate 4, use the protective cover 8 to fix the first guard plate 3 and the second guard plate 4, ensuring that the fixed guardrail is firmly installed on the base 1. Then, insert the sliding bar 55 into the groove 221, so that the movable guardrail 5 is sleeved outside the fixed guardrail, and fixedly connect the movable end of the telescopic cylinder 7 to the fixing plate 56. By driving the telescopic cylinder 7, the telescopic cylinder 7 drives the whole movable guardrail 5 to move up and down to adjust the height of the guardrail. When the worker is a staff member with a relatively tall height, the movable guardrail 5 can be adjusted upward to increase the overall height of the guardrail, thereby protecting the staff member; when the worker is a staff member with a relatively short height, the movable guardrail 5 can be adjusted downward to reduce the height of the movable guardrail 5 and protect the personal safety of the staff member.

[0043] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present technical content, many changes can be made in the specific implementation manner and application scope. As long as these changes do not depart from the concept of the present utility model, they all belong to the protection scope of this patent.
