Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of modular trenches, and specifically relates to a modular trench support device. Background Technique
[0002] A trench is an engineering method of excavation in the ground or underground, and is widely used in fields such as construction, roads, farmland, and urban landscapes. Modular trenches are a relatively specialized concept, which mainly refers to the practice of adopting modular design concepts and methods in the design, construction, and maintenance processes of trenches. During the trench excavation process, as the excavation depth increases, the soil mass on the excavation surface may collapse or cave in due to factors such as its own gravity and moisture, posing a threat to the lives and property safety of the staff. Therefore, the use of a support device is a key measure to ensure the safety and stability of trench construction.
[0003] Common modular trench support devices usually consist of mechanisms such as retaining plates, slots, sliding seats, insertion rods, and other auxiliary components. The retaining plates are used to support the side walls of the trench on both sides. The slots are located on the surface of the retaining plates, and the sliding seats are components that cooperate with the slots. The insertion rod is a key component connecting the retaining plates. By passing through the insertion holes, multiple retaining plates are connected into a whole, and other auxiliary components include connecting pieces and fastening pieces, etc.
[0004] For traditional modular trench support devices, during use, due to different construction tasks, the depth of the trench is not fixed, and it is necessary to judge according to the on-site situation. The height of the retaining plates on the device is usually fixed, which not only makes the retaining plates with a fixed volume unable to adapt to changes in geological conditions, resulting in poor support effects, but also may lead to safety accidents such as collapses due to insufficient bearing capacity or stability. To solve the above problems, for some modular trench support devices, screw holes are first opened at the corresponding positions of the retaining plates, and bolts pass through the pre-drilled screw holes, ensuring that the heads of the bolts are located outside the retaining plates, and the screw rod parts extend into the adjacent retaining plates for connection, so as to adjust the height of the retaining plates, and improve the support effect, insufficient bearing capacity, and stability. However, in this way, during use, due to factors such as disassembly, assembly, and vibration, it will not only accelerate the wear of the threads on the bolts, increasing the use cost, but also easily loosen, and the connection stability cannot be guaranteed. Therefore, a modular trench support device is proposed. Content of the Utility Model

When connecting the upper mudguard and the lower mudguard, first squeeze the side clamping blocks inward. After the side clamping blocks enter the inside of the T-shaped grooves, the side clamping blocks move to the outer ends of the T-shaped grooves under the action of the telescopic rods and the compression springs, and the fixed insertion rods rise along the fixed side plates under the action of the return springs, so that the tops of the fixed insertion rods are inserted into the bottoms of the side clamping blocks. During the use of this structure, the wear phenomenon accelerated due to factors such as disassembly, assembly and vibration can be reduced. At the same time, the structure is simple, which reduces the cost, and also ensures the connection stability, facilitating the disassembly and assembly operation between the upper mudguard and the lower mudguard.
[0012] Preferably, the connection component is composed of a connection inner cylinder and a connection outer cylinder, and the connection inner cylinder is connected to the corresponding upper mudguard and lower mudguard. The connection outer cylinder is connected to the adjustment component, and the distance between the two baffle components is adjusted through the connection inner cylinder, so that the device can be applied to trenches of different sizes within a certain range.
[0013] Preferably, a limit post is installed at the center of the top of the connection inner cylinder, and a threaded spring is horizontally arranged in the inner cavity of the connection inner cylinder. The connection inner cylinder is connected to the corresponding structure through the limit post and the threaded spring.
[0014] Preferably, a limit arc groove is opened at the top of the connection outer cylinder, and the positional relationship and size of the limit arc groove correspond to those of the limit post. First, connect the connection outer cylinder and the connection inner cylinder, and the limit post corresponds to the outer end of the limit arc groove. Then rotate the connection outer cylinder so that the limit post fits with the inner end of the limit arc groove, and the threaded spring applies a certain extrusion force to the connection outer cylinder, so that the limit post and the inner end of the limit arc groove are tightly fitted. It can not only realize the connection between the baffle component and the adjustment component through the connection inner cylinder and the connection outer cylinder, but also facilitate the disassembly and assembly operation.
[0015] Preferably, the adjusting component includes a hollow plate body, guide plates are additionally arranged at the upper and lower parts of the inner cavity of the hollow plate body, and positioning holes are uniformly formed in the tops of the guide plates. Two groups of guide plates in the hollow plate body are respectively connected to the corresponding connection components.
[0016] Preferably, a positioning column is inserted into the top of the hollow plate body, arc-shaped springs are installed at the front end and the rear end of the bottom of the hollow plate body, and connecting insertion columns are connected to the ends of the arc-shaped springs. After the two groups of guide plates drive the corresponding connection components and the baffle component to move, the positioning column is inserted into the positioning hole through the hollow plate body for connection, and the connecting insertion column enters the lower part of the connecting insertion column for insertion connection under the action of the arc-shaped spring. Thus, the stability of the adjusting component after adjustment is ensured.
