Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a trench support device. Background Technology

[0002] In recent years, with the continuous development of the social economy, the awareness of environmental protection has also been continuously strengthened. However, in some narrow places with poor geological conditions, limited working space in narrow tunnels, and inability to slope excavation or allow machinery to enter the site, it is necessary to adopt the construction operation method of simple trench support to ensure the safety and quality of construction.

[0003] An existing application (application number 202022048877.1) discloses a construction trench support structure, including baffles positioned opposite each other on both sides of the trench, a first support rod and a second support rod installed between the two baffles. One end of the first support rod is hinged to one of the baffles, and the other end is provided with a fixing member for connecting the second support rod. One end of the second support rod is detachably connected to the fixing member, and the other end is hinged to a baffle away from the first support rod. The rotation axes of both the first and second support rods are horizontally oriented. The fixing member includes a connecting frame and a screw rod screwed to the connecting frame. The connecting frame has an opening for the second support rod to rotate and be placed inside the connecting frame. A horizontally oriented fixing bolt is also installed inside the connecting frame, and the fixing bolt is vertically inserted into the second support rod. The second support rod has a slotted hole for the fixing bolt to pass through. This construction trench support structure is complex, and the connection between the first and second support rods via the fixing member requires tightening bolts and screws, which is inconvenient for construction workers to assemble and disassemble, resulting in low construction efficiency.

After the support construction is completed, first remove the overlapping piece 7, then remove the first connector 5 and the second connector 6, and finally remove the left baffle 1 and the right baffle 2. This trench support device has a simple structure, is easy to assemble and disassemble, and has high construction efficiency.

[0032] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the first buckle part 32 includes a first bearing surface 321 on the upper side of the left support rod 3 and a first snap-fit ​​part 322 on the first bearing surface 321. The second buckle part 42 includes a second bearing surface 421 on the upper side of the right support rod 4 and a second snap-fit ​​part 422 on the second bearing surface 421. One end of the overlapping member 7 is provided with a first overlapping surface 71 for overlapping on the first bearing surface 321, and the other end is provided with a second overlapping surface 72 for overlapping on the second bearing surface 421.

[0033] When the support is in use, the first overlapping surface 71 overlaps the first bearing surface 321, and the second overlapping surface 72 overlaps the second bearing surface 421. The first fastening part 711 engages with the first locking part 322, and the second fastening part 721 engages with the second locking part 422, so that the left support rod 3 and the right support rod 4 are horizontally connected, thereby forming a support between the left support rod 3, the right support rod 4, and the overlapping part 7. Furthermore, when the support is in use, the first hooking part 11 is located above the hinge of the left support rod 3, and the third hooking part 21 is located above the hinge of the right support rod 4.

[0034] Furthermore, in this embodiment, the first snap-fit ​​portion 322 is a first snap-fit ​​groove, and the first snap-fit ​​portion 711 is a first snap-fit ​​post. The structure is simple, and it is easy to manufacture and operate.

[0035] Furthermore, in this embodiment, the second snap-fit ​​portion 422 is a second snap-fit ​​groove, and the second snap-fit ​​portion 721 is a second snap-fit ​​post. The structure is simple, and it is easy to manufacture and operate.

[0036] Furthermore, in this embodiment, the first latching part 32 is an L-shaped groove opened at the cantilever end of the left support rod 3, and the first bearing surface 321 is formed on the bottom surface of the first latching part 32.

[0038] Furthermore, in this embodiment, the first latching part 32, the second latching part 42, and the overlapping member 7 are at the same height. Thus, when the support is in use, the overlapping member 7 is at the same height as the left support rod 3 and the right support rod 4. The sides of the first latching part 32 and the second latching part 42 can also mate with the end faces of the overlapping member 7 to form a support.

[0039] Furthermore, in this embodiment, the rotation axis of the left support rod 3 is perpendicular to the length direction of the left baffle 1, and the rotation axis of the right support rod 4 is perpendicular to the length direction of the right baffle 2. Thus, during support use, the length directions of the left support rod 3 and the right support rod 4 are arranged along the extension direction of the trench, and the left support rod 3 and the right support rod 4 can rotate vertically. Preferably, both the left baffle 1 and the right baffle 2 are rectangular.

[0040] Furthermore, in this embodiment, both the first connector 5 and the second connector 6 are connecting ropes, which facilitate connection with each hook part (first hook part 11, second hook part 31, third hook part 21 and fourth hook part 41).
