Description

Technical Field

[0001] This utility model relates to the field of earthwork excavation technology, specifically to a protective device for the earthwork excavation process. Background Technology

[0002] Earthwork excavation is a crucial process in the early stages and throughout the construction of an engineering project. It involves loosening, breaking, excavating, and transporting soil and rock. Based on the properties of the soil and rock, earthwork excavation is divided into earth excavation and rock excavation. Earthwork excavation is also classified according to whether the construction environment is open, underground, or underwater, into open excavation, tunnel excavation, and underwater excavation. In water conservancy projects, earthwork excavation is widely used for site leveling and slope cutting, foundation excavation of hydraulic structures, excavation of underground caverns, excavation and dredging of rivers, canals, and ports, quarrying of filling materials, building stones, and concrete aggregates, and demolition of temporary structures such as cofferdams or masonry and concrete structures.

[0003] During the earthwork excavation stage of construction projects, there are many safety hazards. Traditional earthwork excavation slope protection often adopts simple slope treatment or temporary sandbag stacking. However, under complex geological conditions, such as areas with loose soil and high groundwater levels, these methods are difficult to effectively prevent slope collapse. Once the slope becomes unstable, it may bury construction workers and cause serious casualties.

[0004] Most existing protective devices used in earthwork excavation processes are assembled from multiple fixed structures, requiring multiple people to work together to assemble them. The assembly and disassembly process is not only cumbersome but also time-consuming and labor-intensive, causing inconvenience to construction workers. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a protective device for the earthwork excavation process, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a protective device for earthwork excavation, comprising: a base plate, a plurality of first receiving grooves evenly distributed on the top of the base plate, a fixed rod rotatably connected to one end of each first receiving groove, a first connecting rod rotatably connected to the other end of each first receiving groove, a supporting steel plate rotatably connected to one side of the base plate, a plurality of anti-slip grooves evenly distributed on the top of the supporting steel plate, a second receiving groove evenly distributed on the bottom of the supporting steel plate, a connecting seat fixedly connected to one end of each second receiving groove, a second connecting rod rotatably connected to the middle of the connecting seat, and the other end of the second connecting rod rotatably connected to the other end of the first connecting rod.

[0008] Furthermore, a first rotating shaft is fixedly connected to both sides of one end of the first storage slot, and the surface of the first rotating shaft is rotatably connected to one end of the fixed rod.

[0009] Furthermore, a second rotating shaft is fixedly connected to both sides of the other end of the first storage slot, and the surface of the second rotating shaft is rotatably connected to one end of the first connecting rod.

[0010] Furthermore, through holes are provided on both sides of the base plate, and a third rotating shaft is fixedly connected to both sides of the supporting steel plate. The third rotating shaft is rotatably connected inside the through holes.

[0011] Furthermore, a first groove is provided on both sides of the top of the base plate, and several limiting protrusions are uniformly fixedly connected inside the first groove.

[0012] Furthermore, a second groove is provided on both sides of the bottom end of the supporting steel plate, and a support rod is rotatably connected to one end of the second groove. The support rod and the limiting protrusion are connected to each other in a cooperative manner.

[0013] Furthermore, several adjustment holes are provided on both sides of the fixing rod, and fixing bolts are inserted into the adjustment holes. The fixing bolts pass through the first connecting rod to the other side of the fixing rod.

[0014] Furthermore, each of the four corners of the bottom of the base plate is fixedly connected to a mounting base, and a ground nail is inserted into the center of the mounting base.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. With the setting of the first connecting rod, the second connecting rod and the fixing rod, when in use, the support steel plate is adjusted to the angle that adapts to the slope, and then the support rod is pressed against one side of the limiting protrusion to temporarily fix the support steel plate. Then the fixing rod is lifted to find the adjustment hole that matches the first connecting rod, and then the fixing bolt is passed through the adjustment hole and tightened to lock it, thereby achieving the effect of convenient and quick assembly, which can be completed by only one person.

[0017] 2. With the setting of the first and second storage slots, the base plate and the supporting steel plate are rotatably connected during use. When the protective device is retracted, the first connecting rod and the fixing rod are stored inside the first storage slot, and the second connecting rod is stored inside the second storage slot, thereby achieving the effect of smaller size after the protective device is retracted, thus achieving the effect of occupying less space and facilitating transportation.

[0018] 3. By setting the adjustment holes, the adjustment holes are evenly distributed on both sides of the fixed rod during use. Different adjustment holes are selected and the fixed rod is fixed to the first connecting rod with the fixing bolts. This achieves the effect that the support angle of the supporting steel plate can be adjusted at will, thereby achieving the effect of supporting slopes of different angles and improving the scope of application.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-5This is the first embodiment of the present invention, which discloses a protective device for earthwork excavation, comprising: a base plate 1, a plurality of first receiving grooves 101 evenly provided on the top of the base plate 1, a fixed rod 6 rotatably connected to one end of the first receiving groove 101, a first connecting rod 4 rotatably connected to the other end of the first receiving groove 101, a supporting steel plate 3 rotatably connected to one side of the base plate 1, a plurality of anti-slip grooves 305 evenly provided on the top of the supporting steel plate 3, a second receiving groove 301 evenly provided on the bottom of the supporting steel plate 3, a connecting seat 302 fixedly connected to one end of the second receiving groove 301, a second connecting rod 5 rotatably connected to the middle of the connecting seat 302, and the other end of the second connecting rod 5 rotatably connected to the other end of the first connecting rod 4.

[0031] With the first connecting rod 4, the second connecting rod 5, and the fixing rod 6, the supporting steel plate 3 is adjusted to an angle that adapts to the slope during use. Then, the supporting rod 7 is pressed against one side of the limiting protrusion 105 to temporarily fix the supporting steel plate 3. Then, the fixing rod 6 is lifted to find the adjustment hole 601 that matches the first connecting rod 4. Then, the fixing bolt 602 is passed through the adjustment hole 601 and tightened to lock it. This achieves the effect of convenient and quick assembly, which can be completed by only one person.

[0032] Example 2:

[0033] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0034] Both sides of one end of the first storage slot 101 are fixedly connected to a first rotating shaft 102. The surface of the first rotating shaft 102 is rotatably connected to one end of the fixed rod 6. Both sides of the other end of the first storage slot 101 are fixedly connected to a second rotating shaft 103. The surface of the second rotating shaft 103 is rotatably connected to one end of the first connecting rod 4. Both sides of the bottom plate 1 are provided with through holes 106. Both sides of the supporting steel plate 3 are fixedly connected to a third rotating shaft 304. The third rotating shaft 304 is rotatably connected inside the through holes 106.

[0035] With the first storage slot 101 and the second storage slot 301, the base plate 1 and the supporting steel plate 3 are rotatably connected during use. When the protective device is retracted, the first connecting rod 4 and the fixing rod 6 are stored inside the first storage slot 101, and the second connecting rod 5 is stored inside the second storage slot 301, thereby achieving the effect of a smaller volume after the protective device is retracted, and thus achieving the effect of occupying less space and being convenient to transport.

[0036] The top of the base plate 1 has a first groove 104 on both sides. Several limiting protrusions 105 are evenly fixed inside the first groove 104. The bottom of the support steel plate 3 has a second groove 303 on both sides. One end of the second groove 303 is rotatably connected to a support rod 7. The support rod 7 and the limiting protrusions 105 are connected to each other. Several adjustment holes 601 are opened on both sides of the fixing rod 6. Fixing bolts 602 are inserted into the adjustment holes 601. The fixing bolts 602 pass through the first connecting rod 4 to the other side of the fixing rod 6. Fixing seats 2 are fixedly connected at the four corners of the bottom of the base plate 1. Ground nails 201 are inserted into the middle of the fixing seats 2.

[0037] By setting the adjustment holes 601, the adjustment holes 601 are evenly distributed on both sides of the fixed rod 6 during use. Different adjustment holes 601 are selected and the fixed rod 6 is fixed to the first connecting rod 4 by fixing bolts 602, so that the support angle of the supporting steel plate 3 can be adjusted at will, thereby achieving the effect of supporting slopes of different angles and improving the scope of application.

[0038] The remaining structure is the same as that in Example 1.

[0039] The workflow of this utility model is as follows:

[0040] First, place the protective device at the bottom of the earthwork. Then, pass the ground nail 201 through the fixing seat 2 and insert it into the ground to fix the base plate 1. Then, through the setting of the first connecting rod 4, the second connecting rod 5 and the fixing rod 6, adjust the supporting steel plate 3 to adapt to the slope when in use. Then, the supporting rod 7 abuts against one side of the limiting protrusion 105 to temporarily fix the supporting steel plate 3. Then, lift the fixing rod 6 to find the adjustment hole 601 that matches the first connecting rod 4. Then, pass the fixing bolt 602 through the adjustment hole 601 and tighten it to lock it. This achieves the effect of convenient and quick assembly, which can be completed by only one person.

[0041] Secondly, when the protective device needs to be retracted, the fixing bolt 602 is removed, and then the supporting steel plate 3 is lowered to overlap with the base plate 1. Through the setting of the first storage groove 101 and the second storage groove 301, the base plate 1 and the supporting steel plate 3 are rotatably connected during use. When the protective device is retracted, the first connecting rod 4 and the fixing rod 6 are stored inside the first storage groove 101, and the second connecting rod 5 is stored inside the second storage groove 301, so that the protective device is smaller in size after being retracted, thereby achieving the effect of occupying less space and being more convenient to transport.

[0042] Finally, by setting the adjustment holes 601, when in use, the adjustment holes 601 are evenly distributed on both sides of the fixed rod 6. Different adjustment holes 601 are selected and the fixed rod 6 is fixed to the first connecting rod 4 by fixing bolts 602, so that the support angle of the supporting steel plate 3 can be adjusted at will, thereby achieving the effect of supporting slopes of different angles and improving the scope of application.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
