[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0017] By connecting the parts in the case in sequence, the specific connection and operation sequence should be referred to the following working principle, and the detailed connection means is the commonly known technology in the art, and the following mainly introduces the working principle and process.
[0018] In the engineering construction industry, due to the limitation of site conditions, the situation of manual digging of pit holes often occurs. Due to the influence factors such as soil quality, load and depth, the collapse phenomenon occurs in the process of digging pit holes or the dug pit holes, which leads to the workers digging pit holes being buried by mud and stones or the collapse of the dug pit holes, resulting in safety accidents or repeated work. Therefore, the pit hole support is extremely important. The conventional support is to pour concrete support while digging, or to support with wooden boards and square timbers. The former has poor economic performance, high labor cost, material cost and time cost, and basically cannot be modified once formed. The latter has good economic performance, but has low reusability and poor safety;
[0019] Therefore, the present application provides an adjustable pit hole protection plate supporting structure. By cooperating the cross rod and the adjusting device, the overall length of the adjustable pit hole protection plate supporting structure can be changed, thereby supporting pit holes of different volumes, quickly installing, simply adjusting, having low manufacturing cost, and being repeatedly used, thereby greatly facilitating the use of workers, improving the overall work efficiency, effectively supporting the pit hole, and ensuring the construction safety.
[0020] Embodiment one: by Figure 1 , 2It can be known from the above and 4 that the adjustable pit protection plate support structure comprises a cross bar 1, and an adjusting device 2 is arranged on one side of the cross bar 1. The adjusting device 2 comprises a torsion pipe 21, which is rotationally connected to the outer wall of the cross bar 1 through a bearing; a threaded rod 22, which is threadedly connected to the inner wall of the torsion pipe 21 and movably connected to the inner wall of the cross bar 1; and a first clamping block 23, which is installed on one side of the threaded rod 22 and movably connected to the inner wall of the cross bar 1. Wherein, the position between the threaded rod 22 and the cross bar 1 is changed by twisting the torsion pipe 21. In the specific implementation process, it is worth pointing out that the threaded rod 22 can be moved along the inner wall of the cross bar 1 by twisting the torsion pipe 21, and thus the overall length of the adjustable pit protection plate support structure can be changed to support pits of different sizes. Further, the outer wall of the torsion pipe 21 is processed with a grinding line 211. In the specific implementation process, it is worth pointing out that the design of the grinding line 211 can facilitate the twisting of the torsion pipe 21. Specifically, when the overall length of the adjustable pit protection plate support structure needs to be changed during use of the adjustable pit protection plate support structure, the worker twists the torsion pipe 21, the torsion pipe 21 drives the threaded rod 22 to move along the inner wall of the cross bar 1, and thus the position of the adjusting frame 3 can be changed, and the overall length of the adjustable pit protection plate support structure can be changed.
[0021] Embodiment two: by Figure 1 and 2 It can be known that the ends of the cross bar 1 and the threaded rod 22 away from each other are provided with rotating devices 4. The rotating device 4 comprises two supports 41, which are respectively installed at the ends of the cross bar 1 and the threaded rod 22 away from each other; two bases 42, which are respectively rotationally connected to the ends of the two supports 41; and two first limiting screws 43, which are respectively threadedly connected to the inner walls of the two bases 42 and respectively abut against the outer walls of the two supports 41. Wherein, the first limiting screw 43 limits the positions of the support 41 and the base 42. In the specific implementation process, it is worth pointing out that the base 42 can move along the outer wall of the support 41 to adjust the angle of the adjusting frame 3, so as to better facilitate carrying, and the first limiting screw 43 can fix and limit the positions of the support 41 and the base 42. Specifically, on the basis of the above embodiment one, when the angle of the adjusting frame 3 needs to be adjusted, the worker twists the first limiting screw 43. When the first limiting screw 43 is loosened, the position of the base 42 on the outer wall of the support 41 can be adjusted. When the base 42 reaches the appropriate position, the first limiting screw 43 can be used to fix and limit the positions of the support 41 and the base 42.
[0022] Embodiment three: by Figure 1 , 2As shown in FIGS. 1-3, the outer wall of each base 42 is provided with an adjusting frame 3, which comprises: two first supporting plates 31, each mounted on the outer wall of a base 42; two second supporting plates 32, each movably connected to the inner wall of a first supporting plate 31; a plurality of second clamping blocks 33, each mounted on the outer wall of a second supporting plate 32 and movably connected to the inner wall of a first supporting plate 31; and two second limiting screws 34, each threadedly connected to the inner wall of a second supporting plate 32 and abutting against the outer wall of a first supporting plate 31. The second limiting screws 34 limit and fix the first and second supporting plates 31 and 32. In the specific implementation process, it is worth noting that the first and second supporting plates 31 and 32 can be adjusted to fix pit protection plates of different widths, and the second limiting screws 34 can limit and fix the first and second supporting plates 31 and 32. Further, the grooves of the first and second supporting plates 31 and 32 are each provided with a rubber pad 5. In the specific implementation process, it is worth noting that the rubber pad 5 can improve the connection stability between the first and second supporting plates 31 and 32 and the pit protection plate. Specifically, based on the above-mentioned embodiments one and two, when it is necessary to support pit protection plates of different widths, the second limiting screws 34 are twisted by the staff, the position of the second supporting plate 32 in the inner wall of the first supporting plate 31 is changed when the second limiting screws 34 are loosened, and the first and second supporting plates 31 and 32 are limited and fixed by the second limiting screws 34 when the second supporting plate 32 reaches the appropriate position.
