Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel secondary lining steel reinforcement skeleton construction equipment. Background Technology

[0002] In the construction of steel reinforcement cage binding and fabric laying for secondary tunnel lining, the traditional method is to use a construction trolley made of welded steel frame to manually hang fabric and bind and install the steel reinforcement cage. This method has the following main problems: First, during the installation of steel reinforcement, displacement may occur during binding due to the failure to effectively position the reinforcement, resulting in uneven binding and making it difficult to effectively control the construction quality. Second, because the reinforcement cannot be pre-positioned, the hoisting of the reinforcement cannot be completed mechanically in one go, and manual hoisting is time-consuming and labor-intensive. Third, the operating space provided by the trolley is extremely limited, creating blind spots that are difficult to operate in during construction, which leads to safety hazards. Fourth, the fabric hanging is done manually during construction, which is difficult and time-consuming. For the construction of cable trenches in tunnels, the current common method is to use bamboo plywood and steel molds for on-site manual fabrication and installation. After the concrete is poured, the mold is dismantled in a disassembled manner. This method is labor-intensive and time-consuming, and the corners are easily damaged during dismantling, affecting the appearance.

[0003] A search revealed an existing patent (application number: 201610280847.9) that discloses a construction equipment for the steel reinforcement skeleton of tunnel secondary lining and its application. Its characteristic is that a trolley track is laid along the tunnel direction. The trolley frame, composed of a "gate"-shaped steel frame and a "gate"-shaped truss, can move along the trolley track under motor drive. The arched steel frame is constructed by hinged segmented arch top frames and side arch frames, and is supported by the trolley frame. This invention can utilize the arched steel frame to form a positioning jig for the steel reinforcement skeleton, and use the arched steel frame as a support to set up an operating platform. Cable trench formwork can also be installed on both sides of the "gate"-shaped steel frame, thus accommodating the installation of cable trench formwork. This integrated construction of the steel reinforcement skeleton's reinforcement arrangement, binding, installation, and fabric laying in tunnel secondary lining, as well as cable trench laying, provides a safe and reliable working platform for the process, improves project quality, reduces safety hazards, and lowers construction costs. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:

[0004] The construction equipment for the secondary lining steel reinforcement skeleton of this type of tunnel has poor functionality. Its structure is relatively complex and cumbersome, and it lacks sufficient flexibility and adjustability. For example, the lack of structures such as embedded lifting rods and buffer spring rods may affect the flexible adjustment of the construction height and the seismic stability of the structure. Therefore, a construction equipment for the secondary lining steel reinforcement skeleton of tunnel is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a construction equipment for the steel reinforcement skeleton of tunnel secondary lining, thereby solving the problems mentioned in the background art.

An upper frame plate overlaps the outer surface of several of the protective crossbars.

[0010] Furthermore, the arched top frame is arc-shaped and located at the top of the main body of the device, forming a supporting and fixing structure through the top operating platform.

[0011] Furthermore, the supporting top plate, the upper frame plate, and the top operating platform form an upper and lower platform.

[0012] Furthermore, a slide rail is provided on the bottom outer surface of the main body of the device, the movable slider is slidably connected to the inside of the slide rail, a locking bolt is threaded through the outer surface of the movable slider, and multiple connection holes are provided on the outer surface of the movable slider.

The corresponding screw holes of the movable steel frame and the fixed steel frame are internally threaded with adjusting handwheels.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

The advantages of this equipment are its reasonable structure, diverse functions, and ability to efficiently and stably complete the construction task of the tunnel secondary lining steel reinforcement skeleton while ensuring the safety and work efficiency of construction personnel.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please refer to the following: Figures 1-4This utility model provides a technical solution: a tunnel secondary lining steel reinforcement skeleton construction equipment, including a device body 1, with supporting steel frames 2 set at the four corners of the bottom of the device body 1, a fixing plate 3 fixedly connected to the top outer surface of the supporting steel frame 2, and a nested steel frame 6 fixedly connected to the bottom outer surface of the supporting steel frame 2. An embedded lifting rod 7 is set inside the nested steel frame 6, and a supporting plate is fixedly sleeved on the outer surface of the embedded lifting rod 7. A side plate is fixedly connected to the inner wall of the nested steel frame 6, and a buffer spring rod 8 is fixedly connected between the supporting plate and the side plate. Specifically, the elastic deformation of the spring in the buffer spring rod 8 achieves buffering. When the embedded lifting rod 7 descends and impacts, the spring absorbs and disperses the impact force, thereby reducing the vibration and damage to the equipment and enhancing the seismic resistance and stability of the structure.

[0024] In this embodiment, a side support frame 5 is rotatably connected to one side of the supporting steel frame 2, and a movable slider 4 is rotatably connected to the other end of the side support frame 5. Specifically, the side support frame 5 supports the bottom of the supporting steel frame 2 and the device body 1.

[0025] In this embodiment, a drive assembly 9 is provided on the bottom outer surface of the embedded lifting rod 7, and a trolley track 10 is provided at the bottom of the drive assembly 9. Specifically, the equipment moves on the trolley track 10 by the operation of the drive assembly 9 to adjust the construction position.

[0026] In this embodiment, a supporting top plate 13 and several protective crossbars 15 are provided on both sides of the main body 1. An arched top frame 11 is fixedly connected to the other side of the supporting top plate 13. A top operating platform 12 is provided on one side of the arched top frame 11. An upper frame plate 14 overlaps the outer surface of the several protective crossbars 15. Specifically, the supporting top plate 13 and the arched top frame 11 together form a stable construction space. The top operating platform 12 provides a convenient operating platform for construction personnel. The main function of the protective crossbars 15 is to increase the stability and safety of the construction equipment. It can prevent construction personnel or objects from falling from the equipment, and can also resist lateral impacts or pressures to a certain extent, ensuring the smooth progress of the construction process.

[0027] In this embodiment, the arched top frame 11 is arc-shaped and located at the top of the main body 1 of the device, forming a supporting and fixing structure through the top operating table 12.

[0028] In this embodiment, the supporting top plate 13, the upper frame plate 14, and the top operating table 12 form an upper and lower platform.

[0029] In this embodiment, a slide rail is provided on the bottom outer surface of the device body 1. The movable slider 4 is slidably connected to the inside of the slide rail. A locking bolt is threaded through the outer surface of the movable slider 4. Multiple connection holes are provided on the outer surface of the movable slider 4. Specifically, when it is necessary to fix the movable slider 4 in a certain position, the locking bolt is rotated to make it closely contact the slide rail and generate sufficient friction to prevent the movable slider 4 from moving. The connection holes are provided for connecting other construction equipment or tools.

[0030] In this embodiment, the side support frame 5 includes a fixed steel frame and a movable steel frame. The movable steel frame is movably inserted inside the fixed steel frame. Both the fixed steel frame and the movable steel frame have screw holes on their outer surfaces. The number of screw holes on the outer surface of the movable steel frame is several and arranged in a linear array. The screw holes of the movable steel frame and the fixed steel frame are internally threaded with adjusting handwheels. Specifically, by unscrewing the adjusting handwheel, the position of the movable steel frame inside the fixed steel frame is adjusted. Then, by tightening the adjusting handwheel, the movable steel frame and the fixed steel frame are limited. When adjusting the position of the movable slider 4 on the slide rail, the angle of the side support frame 5 changes.

[0031] Working Principle: In use, the main body 1 of this device serves as the core, and is stably connected to the ground via the supporting steel frame 2, ensuring construction stability. The combination of the fixing plate 3 and the nested steel frame 6 provides a reliable installation foundation for the embedded lifting rod 7, enabling flexible adjustment of construction height and position. The synergistic effect of the embedded lifting rod 7, the drive assembly 9, and the trolley track 10 ensures precise movement and positioning of the construction equipment. During the descent of the embedded lifting rod 7, the buffer spring rod 8 slows down the descent, preventing the embedded lifting rod 7 from descending too quickly. The elastic deformation of the spring in the buffer spring rod 8 provides cushioning, reducing the impact when the embedded lifting rod 7 descends. When the spring absorbs and disperses the impact force, it reduces the vibration and damage to the equipment, enhancing the seismic resistance and stability of the structure. The flexible connection between the side support frame 5 and the movable slider 4 facilitates adaptation to different construction scenarios. The supporting top plate 13 and the arched top frame 11 together form a stable construction space. The top operating platform 12 provides a convenient operating platform for construction personnel. The setting of the protective crossbar 15 and the upper frame plate 14 further enhances the safety and convenience during the construction process. The advantages of this equipment are its reasonable structure and diverse functions. It can efficiently and stably complete the construction task of the tunnel secondary lining steel skeleton, while ensuring the safety and work efficiency of construction personnel.
