Description

Technical Field

[0001] This utility model relates to the field of trench support technology, specifically to an integrated transverse plate support structure. Background Technology

[0002] After the trench is excavated, construction workers need to work under the pit wall. However, the pit wall is at risk of collapsing at any time. To prevent construction workers from working under the exposed pit wall during trench excavation and to ensure the safety of trench construction, support structures are usually installed between the pit walls to prevent the pit wall from collapsing and causing casualties.

[0003] However, due to the significant changes in pipelines in current municipal pipeline projects, the existing support structures cannot adjust the horizontal spacing according to the actual situation. Small horizontal spacing makes pipeline installation difficult, and may even require dismantling the supports before hoisting, which in turn poses safety hazards in the trench. Using support structures with larger horizontal spacing will increase transportation and maintenance costs, resulting in significant economic waste. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, this utility model provides an integrated transverse plate support structure to solve the problem that existing pipeline engineering projects have significant pipeline variations, and the support structure cannot adjust the horizontal spacing according to the actual situation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An integrated transverse plate support structure includes two support plates, each vertically placed in a trench, the two support plates being symmetrically arranged about the central axis of the trench; connecting components, two connecting components being symmetrically fixedly installed on the inner side of each support plate; and adjusting components, the two opposite connecting components being connected by adjusting components; the adjusting components are slidable along the connecting components, and the adjusting components are capable of adjusting the spacing between the support plates.

[0006] In this way, by adjusting the two connecting components that are directly opposite each other, the two support plates are assembled into a whole. At this time, the side of the overall support structure is H-shaped. After assembly, the adjusting component is slid on the connecting component to a suitable position. Specifically, the suitable position means that the support plates at both ends of the adjusting component can be evenly stressed. After the position is adjusted, the adjusting component is driven to adjust the distance between the two support plates. At this time, the sides of both support plates are abutting against the inner wall of the trench. With this structure, the horizontal distance between the support plates can be adjusted according to the actual working conditions, thereby improving the applicability of this support structure and reducing the possibility of safety hazards in the trench.

[0007] Furthermore, the connecting assembly includes a slide rail fixedly installed inside the support plate. The slide rail is vertically arranged, and two sliding shoes are slidably connected inside the slide rail. The two sliding shoes facing each other between the two support plates are connected by the adjusting assembly, thereby allowing the adjusting assembly to slide along the slide rail and adjust the adjusting assembly to a suitable position, reducing the possibility of uneven force on the support plate.

[0008] Furthermore, the adjustment assembly includes a first sleeve fixedly connected to the slipper, a hydraulic rod fixedly installed inside the first sleeve, and two mounting slots symmetrically opened inside the first sleeve, each of which is fixedly installed with a first rack. The output end of the hydraulic rod is fixedly connected to a second sleeve. Two through slots are symmetrically opened on both sides of the second sleeve. Gears are rotatably installed in the two through slots. The two gears are respectively meshed with the first rack located on the same side. A support rod is slidably disposed inside the second sleeve. A fixing block is fixedly installed at one end of the support rod facing the hydraulic rod. A second rack is fixedly installed on both sides of the fixing block. The two gears are respectively meshed with the second rack located on the same side. The end of the support rod away from the hydraulic rod is fixedly connected to the slipper on the support plate on the other side.

[0009] In this way, when it is necessary to adjust the horizontal distance between the support plates, the hydraulic rod is activated to push the second sleeve to move. During the movement of the second sleeve, a relative displacement occurs between the gear and the first rack, and the gear meshes with the first rack, thereby driving the two gears to start rotating simultaneously. The gear meshes with the second rack. When both gears start rotating simultaneously, they drive the second rack to move. Specifically, the second rack moves away from the hydraulic rod, causing the support rod to move together. Similarly, when the support plate is not needed, the hydraulic rod is activated to move the second sleeve. After moving a certain distance, the second sleeve returns to the first sleeve, and at the same time, the support rod returns to the second sleeve. With this structure, the horizontal spacing between the support plates can be adjusted according to the actual working conditions, while saving space for placing the support plates and reducing transportation costs.

[0010] Furthermore, the slide rail has evenly spaced limit holes on both sides, and the slide shoe has threaded holes on both sides. A screw is threaded into the limit hole, and the end of the screw can be threaded into the threaded hole, thereby positioning the slide shoe and improving the stability of the support structure.

[0011] Furthermore, a protective edging is fixedly installed on the top surface of the support plate, which can protect the support plate and reduce the possibility of damage to the support plate during the support process.

[0012] Furthermore, lifting lugs are symmetrically fixedly installed on the inner side of the support plate, which facilitates the hoisting of the support plate. At the same time, the lifting lugs are located on the inner side of the support plate, reducing the possibility of damaging the lifting lugs when the excavating equipment presses on the top of the support plate.

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] Example 1: like Figures 1-5 As shown, this utility model discloses an integrated horizontal plate support structure, comprising two support plates 1, which are vertically placed in a trench, and the two support plates 1 are symmetrically arranged about the central axis of the trench; connecting components 2, two connecting components 2 are symmetrically fixedly installed on the inner side of each support plate 1; adjusting components 3, the two opposite connecting components 2 are connected by adjusting components 3; adjusting components 3 can slide along the connecting components 2, and adjusting components 3 can adjust the spacing between the support plates 1.

[0017] In this way, by connecting the two opposing connecting components 2 with the adjusting component 3, the two support plates 1 are assembled into a whole. At this time, the side of the overall support structure is H-shaped. After the assembly is completed, the adjusting component 3 is slid on the connecting component 2 to a suitable position. Specifically, the suitable position means that the support plates 1 at both ends of the adjusting component 3 can be evenly stressed. After the position is adjusted, the adjusting component 3 is driven to adjust the distance between the two support plates 1. At this time, the sides of the two support plates 1 are abutting against the inner wall of the trench. With this structure, the horizontal distance between the support plates 1 can be adjusted according to the actual working conditions, thereby improving the applicability of this support structure and reducing the possibility of safety hazards in the trench.

[0018] The connecting component 2 includes a slide rail 201 fixedly installed on the inner side of the support plate 1. The slide rail 201 is vertically arranged, and two sliding shoes 202 are slidably connected inside the slide rail 201. The two sliding shoes 202 facing each other between the two support plates 1 are connected by an adjusting component 3. Thus, the adjusting component 3 can slide along the slide rail 201 to adjust the adjusting component 3 to a suitable position and reduce the possibility of uneven force on the support plate 1.

[0019] Adjustment component 3 includes a first sleeve 301 fixedly connected to the slipper 202. A hydraulic rod 302 is fixedly installed inside the first sleeve 301. Two mounting slots 303 are symmetrically opened inside the first sleeve 301. A first rack 304 is fixedly installed in each of the two mounting slots 303. The output end of the hydraulic rod 302 is fixedly connected to a second sleeve 305. Two through slots 306 are symmetrically opened on both sides of the second sleeve 305. Gears 307 are rotatably installed in the two through slots 306. The two gears 307 are respectively meshed with the first rack 304 located on the same side. A support rod 308 is slidably disposed inside the second sleeve 305. A fixing block 309 is fixedly installed on the end of the support rod 308 facing the hydraulic rod 302. A second rack 310 is fixedly installed on both sides of the fixing block 309. Two gears 307 are respectively meshed with the second rack 310 located on the same side. The end of the support rod 308 away from the hydraulic rod 302 is fixedly connected to the slipper 202 on the other side of the support plate 1.

[0020] Thus, when it is necessary to adjust the horizontal distance between the support plates 1, the hydraulic rod 302 is activated, pushing the second sleeve 305 to move. During the movement of the second sleeve 305, the gear 307 and the first rack 304 are relatively displaced, and the gear 307 and the first rack 304 are meshed and connected, thereby driving the two gears 307 to start rotating at the same time. Gear 307 meshes with second rack 310. After both gears 307 start to rotate at the same time, they drive second rack 310 to move. Specifically, second rack 310 moves away from hydraulic rod 302, driving support rod 308 to move together. Similarly, when the support plate 1 is not needed, the hydraulic rod 302 is activated, which moves the second sleeve 305. After moving a certain distance, the second sleeve 305 returns to the first sleeve 301. At the same time, the support rod 308 returns to the second sleeve 305. With this structure, the horizontal distance between the support plates 1 can be adjusted according to the actual working conditions, while saving the space for placing the support plates 1 and reducing transportation costs.

[0021] The slide rail 201 has evenly spaced limit holes 401 on both sides, and the slide shoe 202 has threaded holes 402 on both sides. The limit holes 401 are threaded with screws 403, and the ends of the screws 403 can be threaded into the threaded holes 402, thereby positioning the slide shoe 202 and improving the stability of the support structure.

[0022] The top surface of the support plate 1 is fixedly equipped with a protective edging 5, which can protect the support plate 1 and reduce the possibility of damage to the support plate 1 during the support process.

[0023] Lifting lugs 101 are symmetrically fixedly installed on the inner side of the support plate 1, which facilitates the lifting of the support plate 1. At the same time, the lifting lugs 101 are located on the inner side of the support plate 1, which reduces the possibility of damaging the lifting lugs 101 when the excavating equipment presses on the top of the support plate 1.

[0024] Example 2: like Figure 6 As shown, the other features of Example 2 are the same as those of Example 1, except that: A positioning ring 601 is fixedly installed on the outer side of the end of the second sleeve 305 away from the hydraulic rod 302. The positioning ring 601 has a positioning groove 602 on its surface. The support rod 308 has a threaded groove 603 evenly opened on one side of the positioning groove 602. A fastener 604 is slidably connected to the inner side of the positioning groove 602. The fastener 604 can be threadedly connected to the threaded groove 603.

[0025] In this way, after adjusting the spacing between the support plates 1 by adjusting component 3, the fastener 604 is rotated. The fastener 604 passes through the positioning groove 602 and is threadedly connected to the threaded groove 603. Specifically, the fastener 604 is a self-tightening bolt. After the fastener 604 is threadedly connected to the threaded groove 603, the support rod 308 is limited and fixed. With this structure, the adjusting component 3 can be limited and the length of the adjusting component 3 can be fixed, reducing the load on the support rod 308 and reducing the possibility of the support rod 308 retracting due to its inability to support the support plate 1, which could lead to a safety accident.

These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
