Description

Technical Field

[0001] This utility model relates to the field of shallow trench protection technology for unfavorable geological sections with a depth of 1-3m, specifically a safety protection device for shallow trenches. Background Technology

[0002] During trench excavation, without reliable safety protection devices, local collapses are common. After a collapse, the soil clods in the trench need to be cleared, which is time-consuming and labor-intensive. Manual excavation carries the risk of injury from collapsing soil. Furthermore, if shallow trenches are more than one meter deep, someone falling into the trench could be injured. Going up and down within the trench is also unsafe, posing a safety risk. Additionally, workers carrying soil clods may bring them into the trench, requiring subsequent cleanup. Therefore, we propose a safety protection device for shallow trenches to address these potential problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment: a safety protection device for shallow trenches includes a base plate 1, with toothed nails 2 welded to the bottom of the base plate 1, and protective plates 3 bolted to both sides of the base plate 1. A first hinge block 4 is welded to the side of each set of protective plates 3 that is close to each other, and a connecting rod 6 is hinged to the side of each set of first hinge blocks 4 that is close to each other. A second hinge block 7 is hinged to the end of each set of connecting rods 6 that is close to each other, and a threaded rod 8 is provided on the side of each set of second hinge blocks 7 that is close to each other. A threaded tube 9 is provided on the side of each set of threaded rods 8 that is close to each other. The lower "L"-shaped end of the base plate 1 can accommodate the protective plate 3, and bolt interfaces are provided on both sides of the front of the base plate. The base plate 1 and the protective plate 3 are connected by bolts 10 and washers 11 through the bolt interfaces.

[0020] In this embodiment, the threaded tube 9 is matched with the threaded rod 8, allowing the threaded rod 8 to rotate into or out of the threaded tube 9. The outer threads of the threaded rods 8 on both sides of the threaded tube 9 are arranged in opposite directions. When rotating the threaded tube 9, the threaded rod 8 can be rotated into or out of the threaded tube 9 simultaneously. A through hole is provided in the middle of the threaded tube 9, allowing the insertion of appropriate tools into the through hole to facilitate the rotation of the threaded tube 9. Multiple anti-slip rods 5 are provided on the side of the two sets of protective plates 3 that are close to each other, serving as anti-slip measures. The bolt 10 is connected to the base plate 1 and the protective plate 3 by bolting through the bolt interface. A washer 11 is provided at the end of the bolt 10 located on the outside of the base plate 1. The protective plate 3 is provided with a bolt interface that matches the position of the base plate 1, enabling effective bolting.

[0021] The working principle and usage process of this utility model are as follows: This safety protection device for shallow trenches firstly involves driving the toothed nails 2 at the bottom of the base plate 1 into the soil layers on both sides of the trench bottom to increase the bottom support force of the protection device. Bolts 10 and washers 11 are used to connect the base plate 1 and the protective plate 3 through a bolt interface. After rotating the protective plate 3 to the corresponding angle, the threaded tube 9 can be rotated, allowing the threaded rod 8 inside the threaded tube 9 to be rotated out. The second hinge block 7 can then be placed against one side of the protective plate 3, thereby achieving the purpose of supporting the protective plate 2 through the threaded tube 9 and threaded rod 8, reducing the possibility of trench collapse. Simultaneously, the anti-slip rod 5 allows personnel to grip the threaded tube 9 and threaded rod 8 when going up or down the trench, and step on the anti-slip rod 5 to move up and down. Furthermore, the protective plate 3 prevents a large amount of soil from falling into the shallow trench.
