Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a safety protection structure suitable for edge work. Background Art

[0002] In the existing safety protection technology for high-altitude operations, common safety protection structures for edge work are usually composed of fixed railings and non-adjustable protective plates. These guardrail structures are relatively simple and are generally suitable for construction areas of fixed sizes. They cannot be adjusted as the working space changes. During application, if workers accidentally touch the guardrail when working at the edge, they may lose their balance due to the non-adjustability of the guardrail, increasing the risk of falling. The use scenarios of such guardrails are usually limited to building construction, maintenance and other occasions that require high-altitude operations.

[0003] However, the structure of the guardrail in the prior art limits the protective effect when workers accidentally touch it, and there is a great safety risk. At the same time, the fixed guardrail is not flexible enough when dealing with changes in the construction area, and cannot meet the diverse needs for safety protection in different working environments. In particular, as the construction period shortens and the construction area gradually shrinks, the existing guardrail cannot be adjusted and cannot meet the use needs. Therefore, there is an urgent need for a high-altitude work safety protection structure that can be adjusted according to changes in the working environment and provide more reliable protection.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 5 The utility model provides a technical solution: a safety protection structure suitable for working near an edge, comprising: a railing 1, a plurality of limit blocks 2, a cylinder member 3, a supporting rod 5, a rotating mechanism, a guardrail plate 6 and a positioning mechanism, wherein the plurality of limit blocks 2 are rotatably arranged on the outer side of the outer wall of the uprights on both sides of the railing 1; the plurality of cylinder members 3 are rotatably arranged on the railing 1, and themselves are provided with a plurality of limit grooves 4, and the upper ends of the plurality of limit grooves 4 are also provided with a plurality of recesses, and the plurality of cylinder members 3 can rotate within a certain range on the uprights on both sides of the railing 1 through their own limit grooves 4 and limit blocks 2; one end of the plurality of supporting rods 5 is respectively fixedly arranged on the outer side of the outer wall of the plurality of cylinder members 3; the rotating mechanism is arranged on the other end of the plurality of supporting rods 5; one side of the guardrail plate 6 is respectively fixedly installed on the rotating mechanism; the positioning mechanism is respectively arranged on one side of the rotating mechanism and the guardrail plate 6.

[0020] When the guardrail 1 is in use, the staff first lifts the guardrail 6 upward, thereby driving the cylinder 3 to move upward. At this time, the depression at the end of the limit groove 4 is disengaged from the limit block 2, and then the guardrail 6 is continuously pulled in the horizontal direction, and the cylinder 3 begins to rotate on the vertical rod of the guardrail 1 through the limit groove 4. During the rotation process, the upper and lower ends of the limit block 2 are always in contact with the upper and lower ends of the limit groove 4 until the depression at the other end of the limit groove 4 cooperates with the limit block 2. At this time, the guardrail 6 is completely separated from the guardrail 1 and presents an unfolded state, so that the staff can be in a safe area even if they accidentally touch the guardrail 6 during the edge operation, reducing the risk of personnel falling. If the construction area is reduced, the limit block 2 can be matched with the depression in the middle part of the limit groove 4 to adjust the position between the guardrail 6 and the guardrail 1 to a suitable distance to adapt to the changes in the construction area.

[0021] In some examples, further, the rotating mechanism includes: a slide 7, a hinge seat 8 and a pin 9, a plurality of slides 7 are respectively arranged on one side of the guardrail plate 6, and respectively correspond to a plurality of support rods 5; a plurality of hinge seats 8 are respectively arranged on a plurality of slides 7 and can be moved in a horizontal direction; the ends of a plurality of pins 9 are respectively fixed on a plurality of hinge seats 8, and the middle parts are rotatably connected to the other ends of a plurality of support rods 5.

[0022] During the specific implementation process, it should be noted that when the staff pulls the guardrail plate 6 and unfolds it, the angle of the support rod 5 changes accordingly. At this time, the hinge seat 8 slides on the slide 7, so that the support rod 5 and the guardrail plate 6 are gradually perpendicular to each other. The rotational connection between the pin shaft 9 and the support rod 5 ensures the feasibility of the support rod 5 and the guardrail plate 6 changing from a parallel state to a gradually perpendicular state.

[0023] In some examples, further, the ends of the plurality of support rods 5 are respectively provided with threads, and the threads are screwed to the internal threaded sleeve 10 .

[0024] In the specific implementation process, it should be noted that when the two support rods 5 are on the same horizontal line, the two support rods 5 can be connected and fixed by rotating the internal threaded sleeve 10, thereby ensuring stable contact between the guardrail plate 6 and the railing 1.

[0025] In some examples, further, the maximum rotation angle of the plurality of support rods 5 is less than 90 degrees, which facilitates the staff to fold the guardrail plate 6 and makes the folding process smoother.

[0026] In some examples, further, the positioning mechanism includes: an abutment seat 11 and a support leg 12, a plurality of abutment seats 11 are respectively arranged on one side of the guardrail plate 6 and correspond to the vertical poles at both ends of the railing 1; two support legs 12 are respectively arranged at the bottom end of the guardrail plate 6.

[0027] In the specific implementation process, it should be noted that the abutment seat 11 is set to ensure that the guardrail plate 6 and the railing 1 are at an appropriate distance to prevent damage between the support rod and the pin shaft 9 due to contact between one side of the guardrail plate 6 and the vertical rod of the railing 1.

[0028] In some examples, further, a plurality of connecting holes 13 are provided on the guardrail plate 6 , and the plurality of connecting holes 13 are arranged in groups of two on both sides of the plurality of abutment seats 11 , and binding ropes 14 are provided at the plurality of connecting holes 13 .

[0029] During the specific implementation process, it should be noted that the guardrail board 6 and the railing 1 are bound by passing the binding rope 14 through the connecting hole 13. At this time, the device is in a single-layer protection state, which further ensures the stable connection between the guardrail board 6 and the railing 1. At the same time, the device can be set to multiple groups, so that a closed or semi-closed construction area is formed between the guardrail boards 6. When the guardrail boards 6 and the railing 1 are set to multiple groups, the binding rope 14 can be passed through the adjacent connecting holes 13 between the two guardrail boards 6 to achieve a stable connection between the two guardrail boards 6. At this time, the device is in a double-layer protection state. According to actual usage, the guardrail boards 6 and the railing 1 can be increased or reduced to make them freely combined, and the single-layer or double-layer usage state can be freely switched. It has high flexibility and provides reliable safety protection for high-altitude operations.
