Description

Technical Field

[0001] This utility model relates to the field of engineering support device technology, specifically an adjustable telescopic trench box. Background Technology

[0002] In current trench construction processes, steel box-type structures are commonly used for safety protection. The panels of this structure are made of a single piece of steel plate and are connected by fixed-length braces. Each time this protective structure is used, a crane is required for lifting. Furthermore, if the trench excavation width changes, the braces need to be replaced and adjusted.

[0003] Because the existing trench boxes use integral steel panels, their overall volume and weight are relatively large. During use, a crane is required for movement and installation, and they also require considerable storage space. Furthermore, when the width of the trench changes each time it is excavated, different lengths of bracing rods must be used, which limits their application range to some extent. Additionally, various specifications of bracing rods must be provided, making them inconvenient to use.

[0004] Therefore, an adjustable telescopic trench box is designed to modularize the integrated trench box, enabling multi-modal foldable storage of the trench box and making the trench box adjustable in multiple directions. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adjustable telescopic grooved box, which is used to modularly decompose the integrated grooved box, realize the multi-modal foldable storage of the grooved box, realize the multi-directional adjustability of the grooved box, and enhance the flexibility, mobility and adaptability of the grooved box.

[0006] To achieve the above objectives, an adjustable telescopic trench box is designed, comprising at least two retaining plates, several vertical rib structures, several horizontal rib structures, and several supporting structures. Each retaining plate includes several vertically arranged panels, with at least two adjacent panels in the middle of the retaining plate connected by hinges to allow for folding. The two end panels of each retaining plate are connected to two vertical rib structures on the same side, with a gap between the retaining plate and the vertical rib structures. The retaining plates and at least two vertical rib structures constitute the main body of the trench box, which includes at least two opposing trench box bodies. The horizontal rib structures are movably engaged in the gap between the retaining plates and the vertical rib structures. The supporting structures are telescopic, with their ends respectively connected to the vertical rib structures in the two opposing trench box bodies.

[0007] Preferably, the present invention further includes: the vertical rib structure includes a plurality of vertically arranged vertical rib rods and a plurality of horizontally arranged vertical rib connectors, wherein the two ends of the vertical rib connectors are respectively connected to two adjacent vertical rib rods.

[0008] Preferably, the present invention further includes: the vertical rib structure and the retaining plate are connected by a plurality of panel connectors, and the gap width between the vertical rib structure and the retaining plate is the same as the width of the panel connectors.

[0009] Preferably, the present invention further includes: a plurality of transverse rib supports are provided on the side of the vertical rib structure near the retaining plate, wherein the width of the transverse rib supports is smaller than the gap width between the vertical rib structure and the retaining plate, and is used to support the transverse rib structure.

[0010] Preferably, the present invention further includes: in the two opposing grooved box bodies, the vertical rib structure is provided with a supporting connector on the side near the opposing grooved box body, and the two ends of the supporting structure are respectively sleeved in the supporting connectors of the two opposing grooved box bodies.

[0011] Preferably, the present invention further includes: corresponding through holes are provided at both ends of the supporting structure and on the supporting connector, and the pin passes through the through holes to realize the limiting fit between the supporting structure and the main body of the trench box.

[0014] Preferably, the present invention further includes: the vertical rib structure inside the trench box body is provided with a sliding groove on the side near the opposite trench box body, the sliding groove being used to connect and accommodate the scissor support structure.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] Addressing the shortcomings of traditional trench support boxes, a detachable bracing structure and foldable panels are incorporated, allowing two workers to easily install, disassemble, and move them without the need for a crane. Furthermore, the adjustable-length bracing structure makes the trench support box lighter and occupies less space, significantly improving ease of use.

[0023] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] This utility model relates to an adjustable telescopic trench box, whose components include at least two retaining plates, several vertical rib structures, several horizontal rib structures 1, and several supporting structures. The retaining plates are composed of multiple vertically arranged panels 15, wherein at least two adjacent panels 15 are movably connected by hinges 9, thereby achieving the effect of foldable retaining plates. At both ends of the retaining plates, the panels 15 on the same side are respectively connected to two vertical rib structures, but a gap is intentionally left between the retaining plates and the vertical rib structures. The retaining plates and at least two vertical rib structures together constitute the main body of the trench box, and the trench box includes at least two oppositely arranged trench box main bodies. The horizontal rib structures 1 are movably engaged in the reserved gap between the retaining plates and the vertical rib structures. As for the supporting structures, they adopt a telescopic design, with their two ends respectively cooperating and connecting with the vertical rib structures in the two opposite trench box main bodies.

[0025] Example 1:

[0026] See Figures 1 to 5 This embodiment provides a preferred implementation method.

[0027] Each retaining plate comprises six panels 15, with adjacent panels 15 connected by hinges 9. During unfolding and folding, the panels 15 can rotate and fold around the hinges 9. When folded, adjacent panels 15 can overlap and fit together for compact storage. When unfolded, adjacent panels 15 can move away from each other and unfit together for full unfolding.

[0028] Each vertical rib structure includes four vertically arranged vertical rib rods 5 and several horizontally arranged vertical rib connectors 10. The two ends of the vertical rib connectors 10 are connected to the vertical rib rods 5 respectively, and together with the vertical rib rods 5, they form a frame structure.

[0029] This embodiment includes two opposing trench box bodies, each consisting of two vertical rib structures and a retaining wall. The two vertical rib structures are fixedly connected to the panels 15 at both ends of the retaining wall, and are both located on the same side of the retaining wall.

[0030] On the vertical ribs 5 of the vertical rib structure near the retaining wall, several panel connectors 2 are provided. The two ends of each panel connector 2 are fixedly connected to the panel 15 of the retaining wall and the vertical rib 5 of the vertical rib structure, respectively. Furthermore, in the area between the retaining wall and the vertical rib structure where no panel connectors 2 are provided, a hollow gap is formed, the width of which is the same as the width of the panel connector 2. On the same side as the panel connectors 2 of the vertical rib 5, several horizontal rib supports 6 are also provided, the horizontal rib supports 6 being angle iron structures.

[0031] In this embodiment, the transverse rib structure 1 can specifically be a horizontal bar, which is inserted into the gap between the retaining plate and the vertical rib structure and supported by the transverse rib support 6. The width of the horizontal bar of the transverse rib structure 1 is the same as the width of the gap. By inserting the horizontal bar into the gap, the gap is eliminated, and the folding of the panel 15 is prevented. When the panel 15 is subjected to external force and rotates and folds with the hinge 9, the panel 15 is blocked by the horizontal bar and limited by the impact, thereby locking the unfolded retaining plate and preventing the panel 15 from folding when the retaining plate is subjected to soil pressure.

[0032] On the vertical rib 5 of the vertical rib structure near the main body of the opposing trench box, a supporting connector 11 is also provided. The supporting connector 11 is a horizontally arranged sleeve structure. Below the supporting connector 11, an angle iron-shaped supporting member 3 is also provided. The top edge of the right-angled side of the supporting member 3 is fixedly connected to the supporting connector 11, and the side edge of the right-angled side is fixedly connected to the vertical rib 5, thereby strengthening the structure of the supporting connector 11. The two ends of the supporting structure are respectively fitted into the two supporting connectors 11 of the opposing trench box bodies. Both ends of the supporting connector 11 and the supporting structure have through holes. The first pin 4 passes through the through holes at both ends of the supporting connector 11 and the supporting structure in sequence, thereby limiting and locking the movable cooperation between the supporting connector 11 and the supporting structure.

[0033] The supporting structure includes an inner sleeve 12 and an outer sleeve 13, with the inner sleeve 12 fitted inside the outer sleeve 13 and slidingly engaged. Several through holes are equally spaced on the inner sleeve 12 and the outer sleeve 13. A second pin 16 passes through these through holes sequentially, thereby limiting and locking the sliding engagement of the inner sleeve 12 and the outer sleeve 13.

[0034] On the same side of the vertical rib structure, there is also a sliding groove 7. The two ends of the scissor support structure 14 are respectively set in the sliding groove 7 of the vertical rib structure of the opposite groove box body. The scissor support structure 14 can be fixedly fitted in the sliding groove 7 by the connecting flange 8.

[0035] The specific working method of this embodiment is as follows:

[0036] First, measure and excavate the trenches to be dug. Select the appropriate number and size of vertical rib structures and retaining plates according to the requirements, and fix the vertical rib structures and retaining plates together to form two trench box bodies.

[0037] Two trench box bodies are placed facing each other in the trench. The retaining plate of the trench box body is unfolded so that the panel 15 unfolds into a continuous large plane. The horizontal rib structure 1 is inserted into the gap between the retaining wall and the vertical rib structure to complete the limiting and fixing of the unfolded retaining wall. The retaining plate is then attached to the soil surface of the trench.

[0038] The two ends of the scissor support structure 14 are opened into the groove 7. The scissor support structure 14 is driven to open to both sides by hydraulic or other means, so that the two trench box bodies are as far apart as possible and fit as closely as possible with the trench soil layer.

[0039] At this point, both ends of the bracing structure are fixed to the bracing connector 11 by the first pin 4. Then, the inner sleeve 12 and the outer sleeve 13 are pulled and slid away from each other until they can no longer slide. At this point, the second pin 16 is passed through the through holes on the inner sleeve 12 and the outer sleeve 13 in sequence to fix the bracing structure. At this point, the driving force of the scissor support structure 14 can be released, the scissor support structure 14 can be contacted to support the main body of the trench box on both sides, and the scissor support structure 14 can be removed for the next working section.

[0040] After completing the trench construction, use the scissor brace structure 14 to slightly pry open the two trench box bodies, pull out the second pin 16, then pull out the first pin 4, and remove the support structure. Then remove the scissor brace structure 14, then remove the cross rib structure 1, and fold the panel 15 sequentially around the hinge 9 as the rotation center. Remove the folded trench box body from the trench and store it together with the support structure and the scissor brace structure 14.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
