Description

Technical Field

[0001] This utility model belongs to the field of safety protection, specifically a safety protection device for engineering applications. Background Technology

[0002] On construction sites, risks such as falling objects from heights and personnel accidentally entering hazardous work areas are frequent. Safety protection devices are crucial facilities for ensuring the personal safety of construction workers and preventing equipment damage. Whether it is edge protection during the main structure construction phase or area isolation during the decoration and finishing phase, reliable protective devices are needed to delineate safe areas and work areas, reducing the probability of safety accidents. Existing safety protection devices for engineering projects are mostly fixed guardrails or dense mesh nets. Their structure and protection range are usually fixed and difficult to adjust flexibly. When the construction area changes or the protection area needs to be temporarily expanded, the existing devices are not adaptable enough. They need to be disassembled or added, which is cumbersome and inefficient. They are difficult to adapt to the protection scenarios of irregular work areas, resulting in poor protection flexibility and failing to fully meet the diverse protection needs of construction sites.

[0003] Therefore, those skilled in the art have proposed an engineering safety protection device to address the problems raised in the background art. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a safety protection device for engineering applications.

[0005] An engineering safety protection device includes a protective plate, a storage cavity is provided on the rear side of the protective plate, and two sliding grooves are provided on the rear side of the protective plate that are symmetrically distributed vertically and communicate with the storage cavity. Two sets of auxiliary protection components that cooperate with the protective plate are provided in the storage cavity and the sliding grooves. A locking component is provided on the protective plate to lock the position of the auxiliary protection components. The auxiliary protection component includes two sliders that are slidably disposed in two grooves. Each slider has a rotating shaft on the side that is far apart from the other, and a second protective plate is disposed on the side that is close to the other. The second protective plate is located inside the storage cavity.

[0006] Preferably, each of the two protective plates has a vertical plate on the side away from each other, and a handle is provided on the side of the vertical plate away from the protective plate.

[0007] Preferably, a mounting plate is provided at the lower rear end of the second protective plate, and a threaded rod is provided on the mounting plate.

[0008] Preferably, the upper part of the protective plate has a rectangular opening that communicates with the upper sliding groove. The locking assembly includes a movable plate that is slidably disposed in the rectangular opening. The movable plate has a plurality of locking holes arranged in a linear array. The upper part of the protective plate is threaded with a threaded rod, the bottom end of which passes through the rectangular opening and is rotatably connected to the upper part of the movable plate.

[0009] Preferably, each of the two upper sliders is provided with a locking rod that is adapted to the locking port, and the locking rod is inserted into the corresponding locking port.

[0010] Preferably, warning signs are provided on the front side of both the first protective plate and the second protective plate.

[0011] Preferably, two symmetrically distributed limiting blocks are provided at both the upper and lower ends of the rear side of the protective plate via a damping shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model, through the provision of auxiliary protective components and locking components, allows the second protective plate to be pulled out from the storage cavity of the first protective plate. The second protective plate can be fixed by the cooperation of the locking rod and the locking port, thereby temporarily expanding the protective area according to changes in the construction area. At the same time, combined with the unlocking and locking of the limit block, the second protective plate can rotate around the rotation axis, which can adapt to irregular working areas, providing high protection flexibility and thus ensuring stable protection.

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0016] As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a safety protection device for engineering applications, including a protective plate 1, a storage cavity 2 on the rear side of the protective plate 1, two symmetrically distributed grooves 3 on the rear side of the protective plate 1 that communicate with the storage cavity 2, two sets of auxiliary protection components 4 that cooperate with the protective plate 1 are provided in the storage cavity 2 and the grooves 3, and a locking component 5 is provided on the protective plate 1 to lock the position of the auxiliary protection components 4.

[0017] In construction sites, safety protection can be achieved through protective plate 1. When the construction area changes or the protection area needs to be temporarily expanded, the locking component 5 can be used to cancel the limit lock on the auxiliary protection component 4. Then, the auxiliary protection component 4 can be pulled to move and cooperate with the protective plate 1, which can expand the protection range. It is simple and convenient.

[0018] refer to Figure 3 , Figure 4 and Figure 6 The auxiliary protection component 4 includes two sliders 41 that are slidably disposed in two slide grooves 3 respectively. Each slider 41 has a rotating shaft 42 rotatably disposed on the side away from each other. The two rotating shafts 42 are provided with a second protective plate 43 at the end that is close to each other, and the second protective plate 43 is located in the storage cavity 2.

[0019] refer to Figure 2 , Figure 3 and Figure 4 The upper part of the protective plate 1 has a rectangular opening 6 that communicates with the upper sliding groove 3. The locking assembly 5 includes a movable plate 51 that is slidably disposed in the rectangular opening 6. The movable plate 51 has multiple locking holes 52 arranged in a linear array. The upper part of the protective plate 1 is threaded with a threaded rod 53. The bottom end of the threaded rod 53 passes through the rectangular opening 6 and is rotatably connected to the upper part of the movable plate 51.

[0020] refer to Figure 3 and Figure 4 Each of the two upper sliders 41 is provided with a locking rod 48 that is adapted to the locking port 52. The locking rod 48 is inserted into the corresponding locking port 52.

[0021] When auxiliary protective component 4 is needed, the operator can rotate the threaded rod 53. The rotation of the threaded rod 53 causes the moving plate 51 to slide upward within the rectangular opening 6, so that the locking rod 48 on the moving plate 51 moves away from the locking port 52. At this time, the limiting lock on the two upper sliders 41 is canceled. Then, the operator can pull the second protective plate 43 to move within the storage cavity 2, thereby pulling the second protective plate 43 out of the storage cavity 2 and cooperating with the first protective plate 1 to increase the protection range. When the second protective plate 43 moves to the appropriate position, the threaded rod 53 is rotated in the opposite direction again. The threaded rod 53 causes the moving plate 51 to slide downward within the rectangular opening 6 until the locking port 52 on the moving plate 51 is precisely fitted onto the outside of the locking rod 48 of the upper slider 41, realizing the stable insertion of the locking rod 48 and the locking port 52. At this time, the two upper sliders 41 are re-limited and locked, and cannot slide freely along the slide groove 3. The tensile length of the second protective plate 43 is fixed to prevent it from being displaced due to external force collision during the protection process, ensuring that the protection range is stable and reliable.

[0022] refer to Figure 2 and Figure 3 Each of the two protective plates 43 has a vertical plate 44 on the side away from each other, and a handle 45 is provided on the side of the vertical plate 44 away from the protective plate 43.

[0023] When the protective plate 2 43 is pulled to move, the staff can hold the handle 45 and pull the vertical plate 44 to move. The movement of the vertical plate 44 will drive the protective plate 2 43 to move, making it convenient to move the protective plate 2 43.

[0024] refer to Figure 2 and Figure 3 A mounting plate 46 is provided at the lower rear end of the second protective plate 43, and a threaded rod 47 is provided on the mounting plate 46.

[0025] Once the second protective plate 43 is moved to the appropriate position, the staff can rotate the insertion rod 47 to insert it into the soil, thereby ensuring the stability of the first protective plate 1 and the second protective plate 43 during use and preventing the protective position from shifting due to external impact or slight vibration of the site.

[0026] refer to Figure 2 and Figure 6 The upper and lower ends of the rear side of the protective plate 1 are equipped with two symmetrically distributed limit blocks 8, which are rotatably mounted on a damping shaft.

[0027] When it is necessary to adjust the angle of use of the second protective plate 43, the staff can rotate the limit block 8 ninety degrees, which cancels the limit on the second protective plate 43, so that the staff can pull the second protective plate 43 to rotate around the rotating shaft 42.

[0028] When the second protective plate 43 is in the stored state or does not require angle adjustment, the limiting block 8 remains vertical under the action of the damping shaft, thus limiting the second protective plate 43 and preventing it from rotating around the rotating shaft 42 on its own when not in operation. When the angle of the second protective plate 43 needs to be adjusted, the operator can directly move the limiting block 8 to rotate it 90 degrees around the damping shaft to a horizontal state. At this time, the limiting block 8 is completely displaced from the second protective plate 43, and the limiting constraint on the second protective plate 43 is removed. Then the operator can pull the second protective plate 43 to rotate flexibly around the rotating shaft 42 until it is adjusted to the required protective angle. Then the insertion rod 47 is inserted into the soil to ensure the stability of the second protective plate 43 during use.

[0029] refer to Figure 1 and Figure 5 Warning signs 7 are installed on the front side of both protective plate 1 and protective plate 2 43.

[0030] Among them, warning sign 7 can serve as a core warning sign, clearly defining the safety boundary of the entire protected area, further reducing the risk of non-working personnel accidentally entering dangerous areas and construction workers ignoring the protective boundary, and building a solid safety warning defense line for the construction site.

[0031] Working principle: In the initial state, the two sets of protective plates 43 are stored in the storage cavity 2. At this time, the limiting block 8 remains vertical, restricting the rotation of the protective plate 43. The construction area is then protected by the protective plate 1. When the construction area changes and the protected area needs to be expanded, the worker first rotates the threaded rod 53 on the upper part of the protective plate 1. The threaded rod 53 drives the moving plate 51 to slide upwards, causing the locking port 52 to separate from the locking rod 48, thus releasing the limiting lock on the two upper sliders 41. Then, the worker grasps the handle 45 on the side vertical plate 44 of the protective plate 43 and pulls the protective plate 43 along the slide groove 3, pulling it out of the storage cavity 2 to a suitable length. Then, the threaded rod 53 is rotated in the opposite direction to push... The movable plate 51 slides downwards, causing the locking port 52 at the corresponding position to re-engage with the locking rod 48, thus fixing the stretching length of the second protective plate 43. If it is necessary to adjust the protection angle to suit irregular construction areas, the worker moves the limit block 8 to rotate 90 degrees around the damping shaft to a horizontal state, releasing the rotation restriction on the second protective plate 43. The worker then holds the handle 45 and pulls the second protective plate 43 to rotate around the rotating shaft 42 on the slider 41. After adjusting to the required angle, the worker rotates the threaded rod 47 on the mounting plate 46 to insert the rod 47 into the soil, further fixing the position of the second protective plate 43 and preventing it from shaking or tipping over. Ultimately, this achieves the goal of flexibly adjusting the protection range and angle according to construction needs and stably performing the protection function.
