Abstract
Description
A safety protection device for construction engineering Technical Field
[0001] This utility model belongs to the field of construction protection technology, specifically relating to a safety protection device for building construction. Background Technology
[0002] With the rapid development of engineering construction, the number of employees in the construction industry is increasing, and the complex types of work make safety management at construction sites more difficult. Inadequate safety protection facilities and incomplete safety management measures at construction sites can easily lead to safety accidents such as falls by construction workers and falling objects.
[0003] Currently, the common approach to dealing with the impact of construction workers falling is to install support frames on the exterior of the building walls and then install multiple layers of buffer nets on the support frames or to install elastic buffers on the support frames. However, these methods can cause construction workers to bounce upwards when they fall to the last protective net. Since the direction of this upward bounce is uncontrollable, if the bounce direction is biased towards the outside of the protective net, and the falling construction worker may unconsciously roll towards the outside of the protective net due to fright, it can easily cause a secondary fall. Summary of the Invention
[0004] To address the problems mentioned in the background section, this invention provides a safety protection device for construction engineering. The buffer net utilizes an elastic buffer connection structure to provide initial cushioning protection for construction workers. Under impact, the buffer guard rotates inward within the protective support frame. When it reaches its lower limit position, the guard flips over and covers the upper end of the protective support frame, ensuring that construction workers are fully protected within the protective space before rescue arrives, preventing secondary falls.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for construction engineering, comprising a fixed mounting plate, a protective support frame mounted on the fixed mounting plate, a protective net provided around the perimeter and bottom of the protective support frame, a buffer protective plate that flips inwards being hinged to the outer end of the protective support frame via a torsion spring pivot, a protective baffle connected to the upper end of the buffer protective plate, the buffer protective plate flipping inwards within the protective support frame under the downward pulling force of the buffer net via the torsion spring pivot, the protective baffle on the buffer protective plate covering the upper end of the protective support frame, and an elastic buffer connection structure installed on the inner surfaces of the fixed mounting plate, the protective support frame, and the buffer protective plate, and a buffer net being connected through the elastic buffer connection structure.
[0006] As a preferred embodiment, the elastic buffer connection structure includes a guide rod, which is installed in the mounting groove. A connecting slider is guided and slidably mounted on the guide rod. The connecting slider is fixedly connected to the buffer net by a connecting buckle. A first buffer spring is provided at the bottom of the mounting groove, which is sleeved on the lower end of the guide rod and connected to the connecting slider.
[0007] As a preferred embodiment, the lower ends of the buffer protective plate are limited to slide within the arc-shaped limiting grooves on both sides of the protective support frame by limiting slide rods; the two ends of the arc-shaped limiting grooves are connected to limiting blocks that block the limiting slide rods by second buffer springs.
[0008] As a preferred embodiment, a protective pad is provided at the connection between the protective support frame and the fixed mounting plate.
[0009] As a preferred embodiment, the mounting plate is fixedly installed on the exterior wall of the building by bolts.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1) The buffer net of this utility model provides initial buffer protection for construction workers during the downward process by using the elastic buffer connection structure. As the construction workers are impacted, the buffer net continues to move downward and contacts the protective net, which provides secondary buffer protection for the construction workers, thus dealing with situations where the impact force of the fall is large.
[0012] 2) When the buffer protective plate is impacted by the construction workers, it rotates inward through the torsion spring shaft inside the protective support frame. When the buffer protective plate moves to the lower limit position due to the impact force, the protective baffle on the buffer protective plate flips over and covers the upper end of the protective support frame, forming a protective space. Before the rescue arrives, the construction workers are fully protected in the protective space to avoid secondary falls. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] Please refer to Figures 1-5. This utility model provides the following technical solution: A safety protection device for construction engineering includes a fixed mounting plate 1, on which a protective support frame 2 is mounted. The protective support frame 2 is provided with a protective net 6 around its perimeter and bottom. A buffer protective plate 3, which flips inward, is hinged to the outer end of the protective support frame 2 via a torsion spring pivot 21. A protective baffle 31 is connected to the upper end of the buffer protective plate 3. The buffer protective plate 3 flips inward within the protective support frame 2 under the downward pulling force of the buffer net 5 via the torsion spring pivot 21, thus providing buffer protection. The protective baffle 31 on the plate 3 covers the upper end of the protective support frame 2, forming a protective space. Before the rescue arrives, the construction workers are fully protected in the protective space to avoid secondary falls. The inner sides of the fixed installation plate 1, the protective support frame 2 and the buffer protective plate 3 are equipped with an elastic buffer connection structure 4, and a buffer net 5 is connected through the elastic buffer connection structure 4. During the fall of the buffer net 5, the elastic buffer connection structure 4 is used to achieve the first buffer protection for the construction workers, and then the protective net 6 provides a second buffer protection for the construction workers.
[0022] Specifically, the elastic buffer connection structure 4 includes a guide rod 42, which is installed in the mounting groove 41. A connecting slider 43 is guided and slidably mounted on the guide rod 42. The connecting slider 43 is fixedly connected to the buffer net 5 through a connecting buckle. A first buffer spring 44 is provided at the bottom of the mounting groove 41, which is sleeved on the lower end of the guide rod 42 and connected to the connecting slider 43. During the downward movement of the buffer net 5, the connecting slider 43 on the elastic buffer connection structure 4 is pulled to slide downward on the guide rod 42, compressing the first buffer spring 44. The buffer net 5 will provide the first buffer for the construction personnel.
[0023] Specifically, the lower ends of the buffer protective plate 3 are limited to slide within the arc-shaped limiting grooves 7 on both sides of the protective support frame 2 by limiting slide rods 32; the two ends of the arc-shaped limiting grooves 7 are connected by limiting blocks 72 that block the limiting slide rods 32 through the second buffer springs 71; when the buffer protective plate 3 moves to the lower limit position under the impact force, the limiting blocks 72 at the inner end of the arc-shaped limiting grooves 7 support the buffer protective plate 3 under the action of the second buffer springs 71.
[0024] Specifically, a protective pad 8 is provided at the connection between the protective support frame 2 and the fixed mounting plate 1. The protective pad 8 can be an air cushion, a sponge pad, or a rubber pad, which can provide better protection and support for the human body.
[0025] Specifically, the fixed mounting plate 1 is fixedly installed on the exterior wall of the building by bolts.
[0026] The working principle and usage process of this utility model are as follows: In the initial state of use, the buffer protective plate 3 is close to a horizontal state under the action of the torsion spring shaft 21. When a construction worker falls, the worker first comes into contact with the buffer net 5. As the buffer net 5 falls downward, it pulls the connecting slider 43 on the elastic buffer connecting structure 4 to slide downward on the guide rod 42, compressing the first buffer spring 44. The buffer net 5 will provide the first buffer for the worker. Under the impact of the worker, the buffer net 5 continues to move downward and comes into contact with the protective net 6, which provides a second buffer protection for the worker.
[0027] Simultaneously, construction workers will also come into contact with the buffer protective plate 3. The buffer protective plate 3, impacted by the construction workers or pulled downwards by the buffer net 5, rotates inwards within the protective support frame 2 via the torsion spring shaft 21. During this inward rotation, the buffer protective plate 3 guides the construction workers to the position within the protective support frame 2 where the protection is most effective. When the buffer protective plate 3 moves to its lower limit position due to impact, the limiting block 72 at the inner end of the arc-shaped limiting groove 7 supports the buffer protective plate 3 under the action of the second buffer spring 71. The protective baffle 31 on the buffer protective plate 3 flips over and covers the upper end of the protective support frame 2, forming a protective space. Because the buffer protective plate 3 is tilted downwards towards the fixed mounting plate 1, it allows the construction workers to get closer to the fixed mounting plate 1. Simultaneously, under the protection of the protective pad 8, the construction workers are fully protected within the protective space before rescue arrives, preventing secondary falls. When construction workers are in the protected space, the protective barrier 31 located above them can also protect them from falling objects, preventing them from causing injury.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
