DETAILED DESCRIPTION
[0029] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.
[0030] Referring to Figures 1-4 , the embodiment provides a safety protection device for power construction electromechanical installation, comprising:
[0031] The first protective plate 1 is connected with the driving mechanism 2.
[0032] The second protective plate 3 is connected with the output part of the driving mechanism 2, and the driving mechanism 2 can drive the second protective plate 3 to move relative to the first protective plate 1 to change the total area of the vertical projection of the first protective plate 1 and the second protective plate 3, so as to adjust the overall protection area of the safety protection device for power construction electromechanical installation, thereby improving the application range of the safety protection device for power construction electromechanical installation.
[0033] In use, the construction personnel are located directly below the first protective plate 1 and the second protective plate 3, and the construction personnel are protected by the first protective plate 1 and the second protective plate 3 directly below to prevent high-altitude falling objects from hitting the construction personnel.
[0034] For example, in a narrow working environment, the second guard plate 3 is driven by the driving mechanism 2 to move relative to the first guard plate 1, so that the total area of the vertical projection of the first guard plate 1 and the second guard plate 3 is small, thereby being suitable for a narrow working environment. In a spacious working environment, the second guard plate 3 is driven by the driving mechanism 2 to move relative to the first guard plate 1, so that the total area of the vertical projection of the first guard plate 1 and the second guard plate 3 is large, thereby making the protection range of the safety protection device for electric power construction and electrical installation larger to improve the protection area for the workers.
[0035] The driving mechanism 2 can be connected with the first guard plate 1, or connected with the second guard plate 3, or connected with the first guard plate 1 and the second guard plate 3 at the same time, so that the driving mechanism 2 can drive the first guard plate 1 to move relative to the second guard plate 3, or drive the second guard plate 3 to move relative to the first guard plate 1.
[0036] In addition, the first guard plate 1 and the second guard plate 3 can be hinged, for example, one side of the first guard plate 1 is hinged to one side of the second guard plate 3, so that the second guard plate 3 can rotate relative to the first guard plate 1. The rotating direction can be horizontal rotation, or rotation with height change, as long as the total area of the vertical projection of the first guard plate 1 and the second guard plate 3 can be changed.
[0037] In an embodiment, as an alternative to the hinge, the first guard plate 1 and the second guard plate 3 are slidingly connected, and the driving mechanism 2 can drive the second guard plate 3 to move relative to the first guard plate 1 to change the total area of the vertical projection of the first guard plate 1 and the second guard plate 3. The more the total area of the vertical projection of the first guard plate 1 and the second guard plate 3, the smaller the total area of the vertical projection of the first guard plate 1 and the second guard plate 3; the less the total area of the vertical projection of the first guard plate 1 and the second guard plate 3, the larger the total area of the vertical projection of the first guard plate 1 and the second guard plate 3. The advantage of this arrangement is that the first guard plate 1 and the second guard plate 3 are slidingly connected with each other, and have a mutual interaction force of abutting each other, so that they can jointly bear the anti-overturning force, i.e. neither of them is prone to overturning, and the safety is higher. Moreover, by driving the second guard plate 3 to move relative to the first guard plate 1 by the driving mechanism 2, it means that the driving mode of the driving mechanism 2 does not need to change the height of the first guard plate 1 and the second guard plate 3. Even if the first guard plate 1 has a small movement component in the tilting direction relative to the second guard plate 3, the process of changing the height is more stable, reliable and safe. The movement of the second guard plate 3 relative to the first guard plate 1 is equivalent to the movement of the first guard plate 1 relative to the second guard plate 3.
[0038] It should be noted that in the above-mentioned mode in which one side of the first protective plate 1 is hinged to one side of the second protective plate 3, there is no vertical projection of the laminated area of the one side of the first protective plate 1 and the one side of the second protective plate 3, but only the increase and decrease of the total area of the vertical projection of the two.
[0039] In an embodiment, the first protective plate 1 and the second protective plate 3 are laminated, that is, the first protective plate 1 and the second protective plate 3 are always laminated together, and the first protective plate 1 is located below the second protective plate 3, and the second protective plate 3 is supported by the first protective plate 1. In this way, the second protective plate 3 is stacked above the first protective plate 1 to be stably supported by the first protective plate 1 to prevent the second protective plate 3 from overturning.
[0040] In an embodiment, one of the first protective plate 1 and the second protective plate 3 is provided with a sliding groove 11, and the other is provided with a sliding block 31. The sliding groove 11 is provided with an anti-overturning limiting plate 12 extending along the extension direction of the sliding groove 11. The sliding block 31 is in sliding cooperation with the sliding groove 11, and part of the sliding block 31 is located directly below or directly above the anti-overturning limiting plate 12. The arrangement includes a first arrangement and a second arrangement. Figure 1 and Figure 2 In the first arrangement, the first protective plate 1 is provided with the sliding groove 11, and the top of the sliding groove 11 (i.e., the slot of the sliding groove 11) is formed with the anti-overturning limiting plate 12. The second protective plate 3 is provided with the sliding block 31, which is in sliding cooperation with the sliding groove 11, and part of the sliding block 31 is located directly below the anti-overturning limiting plate 12. In the second arrangement (not shown in the figure), the second protective plate 3 is provided with the sliding groove 11, and the bottom of the sliding groove 11 (i.e., the slot of the sliding groove 11) is formed with the anti-overturning limiting plate 12. The first protective plate 1 is provided with the sliding block 31, which is in sliding cooperation with the sliding groove 11, and part of the sliding block 31 is located directly above the anti-overturning limiting plate 12. In the second arrangement, the slot of the sliding groove 11 faces downward, which is not easy to be accumulated with impurities and dust, and the working safety is higher. It can be understood that both arrangements have good anti-overturning function and improve the working safety.
[0041] In an embodiment, the driving mechanism 2 includes a first threaded rod 21 and a first threaded cap 22. One of the first protective plate 1 and the second protective plate 3 is connected to the first threaded rod 21, and the other is connected to the first threaded cap 22. The first threaded cap 22 is threadedly connected to the first threaded rod 21.
[0042] Referring to Figure 2In the embodiment, the first guard plate 1 is connected with the first threaded rod 21, and the second guard plate 3 is connected with the first threaded cap 22. It can be understood that either the first threaded rod 21 drives the first threaded cap 22 to move or the first threaded cap 22 drives the first threaded rod 21 to move can meet the working requirements. In the embodiment, the first threaded rod 21 drives the first threaded cap 22 to move is shown. Figure 2 The first threaded rod 21 drives the first threaded cap 22 to move, so that the movement speed of the second guard plate 3 relative to the first guard plate 1 is stable and reliable, and the slip phenomenon does not occur.
[0043] In an embodiment, the first threaded cap 22 is connected with the limiting piece 4, the first guard plate 1 or the second guard plate 3 connected with the first threaded rod 21 is provided with a limiting slot 13 penetrating through the first guard plate 1 or the second guard plate 3 along the direction of gravity, the limiting piece 4 is located in the limiting slot 13 and can move relative to the limiting slot 13 in the limiting slot 13, and the driving mechanism 2 is located directly below the first guard plate 1 and the second guard plate 3. In the embodiment, the first threaded rod 21 is connected with the first guard plate 1, and thus the limiting slot 13 is provided in the first guard plate 1. In this way, the driving mechanism 2 is located in a relatively concealed position and is protected by the first guard plate 1 and the second guard plate 3, and is not easy to be damaged by impact. It can be understood that the limiting slot 13 serves as a structure for avoiding the limiting piece 4 and absolutely limits the travel of the limiting piece 4, so that the connection relationship between the first guard plate 1 and the second guard plate 3 is more reliable and safe.
[0044] In an embodiment, the first threaded rod 21 has a first threaded section 211 and at least two first connecting sections 212, the first threaded section 211 is located between the two first connecting sections 212, the first threaded section 211 is threadedly connected with the first threaded cap 22, and the two first connecting sections 212 are each sleeved with a first bearing 25 and connected with the first guard plate 1 or the second guard plate 3 through the corresponding first bearing 25. In the embodiment, the two first connecting sections 212 are each sleeved with the first bearing 25 and connected with the first guard plate 1 through the corresponding first bearing 25, and the first threaded cap 22 is connected with the second guard plate 3. In this way, the first threaded section 211 of the first threaded rod 21 does not have a severe rolling friction phenomenon with the first guard plate 1, so that the connection between the first threaded rod 21 and the first guard plate 1 is more smooth. Figure 2
[0045] In an embodiment, in order to facilitate the control of the first threaded rod 21, the first threaded rod 21 is connected with a first rotating disc 23, the first threaded rod 21 is used to drive the first rotating disc 23 to rotate, the first rotating disc 23 is connected with a first handle 24, and the first handle 24 is arranged at the outer edge of the first rotating disc 23. In this way, by manually rotating the first handle 24, the first rotating disc 23 can be operated to rotate, thereby driving the first threaded rod 21, and by converting the rotating movement of the first threaded rod 21 into the translational movement of the first threaded cap 22, the second protective plate 3 is driven to translate relative to the first protective plate 1, so as to change the laminated area of the first protective plate 1 and the second protective plate 3.
[0046] In an embodiment, the power construction and electromechanical installation safety protection device further comprises a rack 5, the first protective plate 1 is installed on the rack 5 and is supported by the rack 5; the rack 5 is installed with a lifting driving assembly 6, the output end of the lifting driving assembly 6 is connected with a lifting plate 7, the bottom of the lifting plate 7 is connected with a plurality of ground spikes 8, the bottom of the ground spike 8 is a pointed structure, and the ground spike 8 is used to be inserted into the ground. When working, the ground spike 8 can be inserted into the ground by driving the lifting plate 7 to descend through the lifting driving assembly 6, so that the rack 5 is not easy to overturn, and it is safer to use. After work, the ground spike 8 can be extracted from the ground by driving the lifting plate 7 to rise through the lifting driving assembly 6. The lifting driving assembly 6 can be a linear motor, an electric push rod or a telescopic cylinder.
[0047] In an embodiment, in order to further improve the anti-overturning function of the rack 5, the lifting driving assembly 6 is provided with a plurality of lifting driving assemblies 6, and the lifting plate 7 is provided with a plurality of lifting plates 7, and the plurality of lifting driving assemblies 6 and the plurality of lifting plates 7 are arranged in one-to-one correspondence.

One of the second threaded rod 62 and the second threaded cap 63 is pivotally connected with the seat body 61, and the other is connected with the lifting plate 7 and is fixedly connected with the lifting plate 7 in the circumferential direction. The two ends of the telescopic rod 64 are respectively connected with the seat body 61 and the lifting plate 7.
