[0033] The temporary hole safety protection device of the utility model sets up the sliding groove 31 on the first cover plate 1, sets up the sliding block 32 of sliding cooperation with the sliding groove 31 on the second cover plate 2, or sets up the sliding block 32 on the first cover plate 1, sets up the sliding groove 31 of sliding cooperation with the sliding block 32 on the second cover plate 2, to form guide rail assembly 3, so that the second cover plate 2 can reciprocate relative to the first cover plate 1 along the guide rail assembly 3, when encountering larger size construction hole, second cover plate 2 can be slid outward and unfolded, increase the protection area, and when encountering smaller size construction hole, second cover plate 2 can be slid inward and folded, reduce the protection area, thereby realizing the adjustability of the protection device area, for example, in the process of construction, when needing to protect 2m * 1m floor hole, second cover plate 2 can be slid and unfolded to the corresponding size, and when needing to protect 1m * 1m floor hole, second cover plate 2 can be appropriately folded, and the first cover plate 1 and the second cover plate 2 are made of metal plate or composite material plate with bending strength not less than 235MPa, to ensure that the protection device has sufficient carrying capacity and high reliability.

[0034] Preferably, the first cover plate 1 and the second cover plate 2 are made of Q235 steel plate, which has good mechanical properties and processing performance, and the bending strength can reach more than 235MPa, can bear various loads on the construction site, and has high toughness and is not easy to brittle fracture when bearing impact, and Q235 steel plate is in sufficient supply on the market, and the procurement price is low, which can significantly reduce the manufacturing cost of the protection device, compared with other metal plates or composite material plates, Q235 steel plate has higher performance price ratio, and is more suitable as the manufacturing material of temporary hole protection device.

[0035] It can be understood that the second cover plate 2 in the case is at least one, that is, the number of the second cover plate 2 can be selected according to specific needs. For example, when the second cover plate 2 is one, the first cover plate 1 can be unfolded or folded through the guide rail assembly 3 and the second cover plate 2. This structure is simple and suitable for small-area construction opening protection; when the second cover plate 2 is two, it can be respectively arranged on both sides of the first cover plate 1, and two-way unfolding or folding can be realized through two groups of guide rail assemblies 3, which can more flexibly adjust the protection area; when the second cover plate 2 is three, the second cover plate 2 can be arranged in three directions of the first cover plate 1, and multi-directional unfolding or folding can be realized through three groups of guide rail assemblies 3, which further improves the application range of the protection device; when the second cover plate 2 is four, the second cover plate 2 can be arranged in four directions of the first cover plate 1, and omnidirectional unfolding or folding can be realized through four groups of guide rail assemblies 3, which maximizes the coverage area of the protection device and meets the protection needs of larger size openings.

[0036] In some embodiments, the guide rail assembly 3 adopts a setting mode of multiple groups of sliding grooves 31 and sliding blocks 32, wherein each group of sliding grooves 31 is arranged parallel to each other, and each group of sliding grooves 31 forms a sliding fit structure with the corresponding sliding block 32. Through this structure of multiple parallel guide rail assemblies 3, the stability and carrying capacity of the second cover plate 2 relative to the first cover plate 1 can be improved. For example, two or three groups of parallel sliding grooves 31 can be arranged on one second cover plate 2, and each group of sliding grooves 31 is in sliding fit with the corresponding sliding block 32 on the first cover plate 1, so as to ensure that the second cover plate 2 runs stably during unfolding and folding and does not tilt or jam. Preferably, referring to Figure 4 , two groups of sliding grooves 31 and sliding blocks 32 constitute the guide rail assembly 3, wherein the sliding block 32 is fixedly arranged on the first cover plate 1, and the sliding groove 31 is fixedly arranged on the second cover plate 2. Through this structure arrangement, two parallel sliding grooves 31 are arranged on each second cover plate 2, and the two sliding blocks 32 at the corresponding positions on the first cover plate 1 form a fit. This double-track structure can not only ensure sufficient carrying capacity, but also make the second cover plate 2 slide more stably and reliably relative to the first cover plate 1.

[0037] In some embodiments, referring to Figure 2The sliding groove 31 is formed by two "L" shaped guide plates 311 arranged oppositely, and the sliding block 32 is designed in a "T" shaped cross section structure, in which the horizontal part of the "T" shaped structure is embedded and slidably arranged in the sliding cavity formed by the two "L" shaped guide plates 311, and the vertical part of the "T" shaped structure is arranged to pass through the gap between the two "L" shaped guide plates 311, so as to prevent the second cover plate 2 from being separated from the guide rail assembly 3 during sliding, for example, when the second cover plate 2 slides relative to the first cover plate 1, the "T" shaped horizontal part of the sliding block 32 moves smoothly in the sliding cavity, and the vertical part is connected with the first cover plate 1 or the second cover plate 2 through the gap, forming a stable guide structure, ensuring the reliable operation of the entire protective device.

[0038] In some embodiments, referring to Figures 2-4 The locking device 4 arranged between the first cover plate 1 and the second cover plate 2 is composed of three main components, namely the fixed pin 41, the locking piece 42 and the rotating shaft 43. The fixed pin 41 is vertically fixed at the edge of the first cover plate 1, the locking piece 42 is pivotally connected to the second cover plate 2 through the rotating shaft 43, and the locking hole 421 for the fixed pin 41 to pass through is arranged on the locking piece 42. When it is needed to lock the second cover plate 2 in the folded position, the locking piece 42 is rotated to make the fixed pin 41 pass through the locking hole 421, so as to realize reliable locking between the first cover plate 1 and the second cover plate 2. For example, when the protective device needs to be temporarily fixed on the construction site, the operator only needs to slide the second cover plate 2 to the folded position, and then rotate the locking piece 42 to make the fixed pin 41 pass through the locking hole 421, so as to quickly complete the locking operation, avoid accidental sliding of the second cover plate 2, and ensure the safety of the protective device.

[0039] In some embodiments, referring to Figures 1-4 The hoisting part 5 is fixedly arranged at the middle position of the first cover plate 1. By arranging the hoisting part 5 at the center position of the first cover plate 1, the entire protective device can be stably hoisted to the specified position of the construction opening by using lifting equipment. For example, when the protective device needs to be hoisted to the construction opening of different floors during the construction of high-rise buildings, the lifting equipment such as a tower crane can be connected with the hoisting part 5 to realize safe and convenient hoisting of the protective device. At the same time, since the hoisting part 5 is located at the middle position of the first cover plate 1, the inclination or shaking during hoisting can be avoided, and the construction efficiency and safety are improved.

[0040] Specifically, the hoisting part 5 has a U-shaped structure, referring to Figure 3 , 4The structure is composed of a bottom edge 51 and two vertical edges 52, wherein the bottom edge 51 is fixedly connected with the first cover plate 1, and the two vertical edges 52 extend upward in parallel to form a space for the lifting device hook to pass through, the hook of the lifting device can easily pass through the space between the two parallel vertical edges 52 and form a stable connection with the hoisting part 5, since the bottom edge 51 is fixedly connected with the first cover plate 1, it can ensure that the entire protective device remains stable during hoisting and does not shake or tilt, and the design of the U-shaped structure also facilitates quick hooking and disengaging of the hook, thereby improving construction efficiency.

[0041] Further, the U-shaped structure is made of steel to ensure sufficient strength and durability, and anti-slip lines are arranged on the surface of the U-shaped structure, which can increase the friction between the hook of the lifting device and the hoisting part 5 to prevent the hook from slipping during hoisting.

[0042] In some embodiments, the second guide rail assembly 3 (not shown) arranged on the second cover plate 2 includes two main components, a second sliding groove 31 and a second sliding block 32, which can be arranged on the second cover plate 2 and the third cover plate respectively, and the sliding connection between the third cover plate and the second cover plate 2 is realized through the sliding cooperation of the second sliding groove 31 and the second sliding block 32, for example, when the protection range needs to be adjusted on the construction site, the second guide rail assembly 3 can be used to slide the third cover plate relative to the second cover plate 2, thereby realizing flexible adjustment of the protection area, and the connection principle between the first cover plate 1 and the second cover plate 2 is similar, that is, reliable sliding guidance is realized through the cooperation of the sliding groove 31 and the sliding block 32, so that the entire protective device can be adjusted in multiple stages according to the construction needs.

[0043] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present application, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
