Description

Technical Field

[0001] This utility model relates to the technical field of bridge and tunnel construction facilities, specifically an auxiliary support device for road bridge and tunnel construction. Background Technology

[0002] Currently, auxiliary support devices are commonly used during bridge and tunnel construction to improve safety during the construction process. Existing auxiliary support devices have good construction capabilities, but bridge and tunnel construction carries a certain risk of collapse. Existing auxiliary support devices cannot provide refuge spaces for construction personnel, thus failing to reduce construction risks.

[0003] However, the existing auxiliary support devices have relatively fixed support structures, and the positions between support points are difficult to change. This brings great inconvenience to actual construction. When the construction site space is small, the construction angle is special, or the construction stage changes, the fixed support points cannot be flexibly adjusted, which may hinder the construction process and reduce construction efficiency. Due to the limitations of the structure, such devices are difficult to provide stable and suitable support under different construction conditions, which increases the difficulty and risk of construction operations and may even affect construction quality and safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: an auxiliary support device for road, bridge and tunnel construction, including a base 1, hydraulic cylinders 2 on both sides of the base 1, a telescopic column 3 at the center of the two hydraulic cylinders 2, a support plate 4 fixedly installed on the top of the two hydraulic cylinders 2, a connecting plate 5 for auxiliary support fixedly installed on the base 1, a rotating shaft 6 on one side of the support plate 4, an extension plate 7 rotatably connected to the rotating shaft 6, pulleys 8 fixedly installed at the bottom of the support plate 4 and above the base 1, and a rope 9 for lifting installed on the pulleys 8.

[0023] Specifically, a reinforcing ring 10 is fixedly installed at the connection between the support plate 4 and the hydraulic cylinder 2. This arrangement makes the connection between the support plate 4 and the hydraulic cylinder 2 more stable, thereby improving the stability and load-bearing capacity of the entire auxiliary support device. The reinforcing ring 10 can also effectively prevent the hydraulic cylinder 2 from loosening or being damaged due to uneven force during long-term use, thus extending the service life of the device.

[0024] Specifically, a fixing ring 11 is fixedly fitted at the connection between the base 1 and the hydraulic cylinder 2, and a fixing ring 11 is also fitted at the connection between the base 1 and the telescopic column 3. These features make the connection between the base 1, the hydraulic cylinder 2, and the telescopic column 3 more secure, further enhancing the stability and safety of the entire device. During construction, even in the face of complex geological conditions or large loads, this auxiliary support device can remain stable, ensuring safe construction.

[0025] Specifically, a reinforcing plate 12 is provided between the two hydraulic cylinders 2. This arrangement makes the structure between the two hydraulic cylinders 2 more stable, effectively preventing deformation or damage to the hydraulic cylinders 2 due to excessive force during operation, and further improving the load-bearing capacity and service life of the entire auxiliary support device.

[0026] Specifically, the telescopic column 3 includes an inner telescopic column 13 and an outer telescopic column 14. The inner telescopic column 13 is slidably connected inside the outer telescopic column 14, and a spring 15 is fixedly installed at the bottom of the inner telescopic column 13. The other end of the spring 15 is fixedly connected to the inner wall at the bottom of the outer telescopic column 14. Through the above configuration, the telescopic column 3 has a certain buffering and shock absorption capacity. During construction, when encountering uneven ground or sudden load changes, the spring 15 can absorb and disperse part of the impact force, effectively reducing the impact on the hydraulic cylinder 2 and the entire device, thereby protecting the device from damage and improving the stability and safety of construction.

[0027] Specifically, a lifting ring 16 is provided at the top of the telescopic inner column 13. This design allows construction personnel to easily connect lifting equipment via the lifting ring 16 for various lifting operations. The design of the lifting ring 16 enhances the functionality of the telescopic column 3.

[0028] Specifically, a connecting rod 17 is provided between the two hydraulic cylinders 2. This arrangement makes the connection between the two hydraulic cylinders 2 tighter, effectively preventing the hydraulic cylinders 2 from shaking or shifting during operation, and further enhancing the stability and reliability of the entire auxiliary support device.

[0029] Specifically, the connecting plate 5 is also fitted with an extension sleeve 18. This design allows the connecting plate 5 to be extended according to actual needs, increasing the flexibility and applicability of the auxiliary support device. During construction, if different widths or heights of roads, bridges, or tunnels need to be constructed, the length of the sleeve 18 can be adjusted to extend or shorten the connecting plate 5, thereby meeting different construction requirements and improving the practicality and adaptability of the device.

[0030] A specific application example of this embodiment is as follows:

[0031] When using this device, first, place the base 1 stably in the construction area, ensuring it is stable and immovable. Then, activate the hydraulic cylinder 2. Through the extension and retraction function of the hydraulic cylinder 2, adjust the height of the support plate 4 to accommodate different construction height requirements. After the support plate 4 is adjusted to the appropriate height, the extension plate 7 can be rotated to fit snugly against the structure of the construction area, further enhancing the support effect. Simultaneously, using the pulleys 8 and ropes 9, various hoisting operations can be easily performed, such as moving construction materials and installing components.
