Description

Technical Field

[0001] This utility model relates to the field of rail transit support technology, specifically a temporary support device for rail transit construction. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or system that requires operating vehicles to run on specific tracks. With the diversified development of train and railway technology, rail transit has presented more and more types, not only covering long-distance land transportation, but also widely used in medium and short-distance urban public transportation. According to the difference in service scope, rail transit is generally divided into three categories: national railway system, intercity rail transit, and urban rail transit. Rail transit generally has the advantages of large capacity, high speed, frequent service, safety and comfort, high punctuality, all-weather operation, low freight cost, and energy saving and environmental protection. However, it is often accompanied by high initial investment, technical requirements and maintenance costs, and often occupies a large space.

[0003] Currently, when developing tunnels for rail transit, supports are installed at the excavated sections to temporarily support the surrounding rock and enhance construction safety. During construction, the excavation length for each section must be determined in advance based on the specific rock conditions, dividing the entire tunnel into multiple segments for sequential excavation. After each segment is excavated, steel arches are installed and secured with reinforcing bars. However, the installation process typically involves using multiple sets of bolts and wires, which is time-consuming and slows down the overall work efficiency. Therefore, we propose a temporary support device for rail transit construction. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary support device for rail transit construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary support device for rail transit construction, comprising a top frame, an arc-shaped groove on the bottom surface of the top frame, arc-shaped plates connected to both ends of the arc-shaped groove, a side frame fixedly connected below the arc-shaped plates, multiple sets of first insert steel members on the top frame, and multiple sets of second insert steel members on the side frame; a connecting assembly, the connecting assembly being disposed at both ends of the top frame and connected to the first and second insert steel members, comprising a first sleeve rod adapted to the first insert steel member and a second sleeve rod adapted to the second insert steel member, the openings of the first sleeve rod and the second sleeve rod facing opposite directions; and a limiting assembly, the limiting assembly being disposed on the connecting assembly and used to operate the first sleeve rod and the second sleeve rod to move simultaneously, solving the problem that the original installation between steel arch frames and reinforcing bars mainly relied on multiple sets of bolts and steel wires, which required a lot of time and resulted in slow overall work efficiency.

[0006] Preferably, the connecting assembly includes two sets of fixed seats respectively disposed at both ends of the top frame and fixedly connected thereto. The fixed seats have multiple sets of insertion slots, and a fixed sleeve is fixedly connected to the fixed seat. A connecting steel is disposed in the fixed sleeve, and the connecting steel is used to connect the top frame and the arc plate. A rotating sleeve is disposed on the outside of the fixed sleeve and rotatably connected to the fixed seat. The rotating sleeve is fixedly connected to the first sleeve rod and the second sleeve rod, and multiple sets of sliding grooves are disposed on the inner side of the rotating sleeve.

[0007] Preferably, the limiting component includes a rotating ring disposed between the fixed sleeve and the rotating sleeve and rotatably connected to the fixed seat. The rotating ring is provided with a tension spring fixedly connected to one end thereto. The tension spring is located between the fixed sleeve and the rotating sleeve, and the other end of the tension spring is fixedly connected to a sliding seat. The sliding seat is fixedly connected with multiple sets of sliding blocks that are slidably connected to the rotating sleeve through the sliding groove. The sliding seat is provided with a connector that is connected to the insertion groove.

[0008] Preferably, the connector includes a connecting plate disposed on and fixedly connected to the sliding seat, a plurality of plug rods adapted to the plug slot are fixedly connected to the connecting plate, and an operating sleeve located outside the connecting steel is fixedly connected to the connecting plate.

[0009] Preferably, the bottom end of the side frame is provided with a mounting groove, and the bottom end of the side frame is provided with a mounting seat adapted to the mounting groove. A support rod is fixedly connected to the bottom end of the mounting seat. A bolt passing through both is provided at the connection between the side frame and the mounting seat. A swinging sleeve rod is provided on the second sleeve rod, one end of which is rotatably connected to it. The other end of the swinging sleeve rod is adapted to the bolt.

[0010] Preferably, the length of the two sets of arc plates is equal to the length of the arc groove. The connection between the arc plate and the top frame and the connecting steel is thickened, which is beneficial for the two sets of arc plates to cooperate and support the top frame. At the same time, the thickening treatment at the connection makes the connection between the whole structure more stable.

[0011] Preferably, the outer side of the operating sleeve is provided with multiple sets of anti-slip strips, which makes the operation of the operating sleeve more stable and convenient.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention solves the problem that the original installation of steel arch frames and reinforcing bars relied on multiple sets of bolts and wires, which was time-consuming and inefficient. By using a connecting component and a limiting component, the installation process involves first inserting the first and second insert steel members into the top and side frames respectively, for lateral connection of the various top and side frames in the tunnel. Then, the connecting steel member passes through the rotating sleeve, the fixed sleeve, and the fixed seat, finally penetrating the connection between the top frame and the arc plate. The limiting component is then used to release the fixing restriction on the connecting component. After adjustment, the first and second rods rotate around the connecting steel member, respectively locking it in place. By changing the overall connection method, the efficiency of the work is improved. Attached Figure Description

[0026] Furthermore, the connecting assembly 7 includes two sets of fixed seats 11 respectively disposed at both ends of the top frame 1 and fixedly connected thereto. The fixed seats 11 have multiple sets of insertion slots 12, and fixed sleeves 13 are fixedly connected to the fixed seats 11. Connecting steel 14 is disposed in the fixed sleeves 13. The connecting steel 14 is used to connect the top frame 1 and the arc plate 3. A rotating sleeve 15 is disposed on the outside of the fixed sleeve 13 and is rotatably connected to the fixed seats 11. The rotating sleeve 15 is fixedly connected to the first sleeve rod 8 and the second sleeve rod 9. Multiple sets of sliding grooves 16 are disposed on the inner side of the rotating sleeve 15. The length of the two sets of arc plates 3 is equal to the length of the arc groove 2. The connection between the arc plate 3 and the top frame 1 and the connecting steel 14 is thickened.

[0027] like Figures 5-8 As shown, the limiting component 10 includes a rotating ring 17 disposed between the fixed sleeve 13 and the rotating sleeve 15 and rotatably connected to the fixed seat 11. A tension spring 18 is disposed on the rotating ring 17 and fixedly connected to one end thereto. The tension spring 18 is located between the fixed sleeve 13 and the rotating sleeve 15, and the other end of the tension spring 18 is fixedly connected to a sliding seat 19. Multiple sets of sliding blocks 20 are fixedly connected to the sliding seat 19 and slidably connected to the rotating sleeve 15 through sliding grooves 16. A connector 21 connected to the insertion groove 12 is disposed on the sliding seat 19 and fixedly connected to it. Multiple sets of insertion rods 23 adapted to the insertion groove 12 are fixedly connected to the connecting plate 22, and an operating sleeve 24 located outside the connecting steel 14 is fixedly connected to the connecting plate 22. In addition, multiple sets of anti-slip strips are disposed on the outside of the operating sleeve 24.

[0028] Furthermore, the bottom end of the side frame 4 is provided with a mounting groove 25, and the bottom end of the side frame 4 is provided with a mounting seat 26 that is adapted to the mounting groove 25. The bottom end of the mounting seat 26 is fixedly connected to a support rod 27. A bolt 28 is provided at the connection between the side frame 4 and the mounting seat 26, which passes through both. A swinging sleeve 29 is provided on the second sleeve rod 9, one end of which is rotatably connected to it. The other end of the swinging sleeve 29 is adapted to the bolt 28. One end of the swinging sleeve 29 is hinged to the second sleeve rod 9, and the other end has a sleeve clamp that can hold the bolt 28.

[0029] In a specific implementation, during installation, the first insertion steel 5 and the second insertion steel 6 are first inserted into the top frame 1 and the side frame 4 respectively, for lateral connection of each set of top frame 1 and side frame 4 in the tunnel. Then, the connecting steel 14 is passed through the rotating sleeve 15, the fixed sleeve 13 and the fixed seat 11, and finally through the connection between the top frame 1 and the arc plate 3. The second insertion steel 6 is located between the second sleeve rod 9 and the swing sleeve rod 29. Then, the operating sleeve 24 is grasped and pulled outward. The operating sleeve 24 drives the insertion rod 23 to move out of the insertion groove 12 on the fixed seat 11 through the connecting plate 22. At the same time, the sliding seat 19 slides outward in the rotating sleeve 15, and the sliding block 20 slides in the sliding groove 16. The sliding seat 19 drives the tension spring 18 to stretch until the insertion rod 23 is completely removed from the insertion groove 12. At this time, the rotating sleeve 15 can rotate on the fixed seat 11.

[0030] Rotate the operating sleeve 24, and the sliding seat 19 will rotate. At the same time, through the cooperation of the sliding block 20 and the sliding groove 16, the rotating sleeve 15 will be driven to rotate. The rotating sleeve 15 will drive the first sleeve rod 8 and the second sleeve rod 9 to swing. The first sleeve rod 8 and the second sleeve rod 9 will swing around the rotating sleeve 15 as the center.

After the operation is completed, the operating sleeve 24 will be lowered at the current angle, the tension spring 18 will be pulled back, and the insert rod 23 will be inserted into another set of insert grooves 12 on the fixed seat 11 to fix the whole in the current state. At this time, the connection between the top frame 1 and the side frame 4 will be more stable because the first sleeve rod 8 and the second sleeve rod 9 will lock the first insert steel 5 and the second insert steel 6 respectively.

[0031] The support rod 27 is used for support at the bottom end. It is inserted into the mounting groove 25 through the mounting seat 26 at the top end and installed with the side frame 4. Then, the bolt 28 is inserted so that it passes through the bottom end of the side frame 4 and the mounting seat 26. The swing sleeve 29 can be operated to swing downwards, and finally the sleeve at the end of the swing sleeve 29 is locked on the bolt 28, further strengthening the overall connection.
