Description

Technical Field

[0001] This utility model relates to the field of tunnel operations, and in particular to a working vehicle for railway tunnels. Background Technology

[0002] The inner walls of railway tunnels are equipped with overhead contact line supports, lighting fixtures, and various lines, which inevitably require high-altitude operations during installation and subsequent maintenance.

[0003] Currently, common aerial work platforms used in tunnels, such as aerial work vehicles, have several drawbacks. Due to their excessive freedom of movement, they are difficult to control. Furthermore, they require support and fixation of the entire machine during use, making it impossible to carry out construction while the machine is in motion.

[0004] In addition, some equipment cannot fully cover the tunnel walls; some equipment is too complex, and the preparation work before and after construction is too cumbersome.

[0005] An existing patent discloses a multi-functional tunnel maintenance vehicle (authorization number CN 115849261 A), which is equipped with a lifting platform. A horizontal guide rail is installed above the lifting platform, and an extension platform is provided that can move along the horizontal guide rail under the drive of a horizontal drive component. However, the adjustable range of the guide rail in this device is limited, and it cannot cover the entire inner wall of the tunnel.

[0006] An existing patent discloses a tunnel working platform (authorization number CN 207313066 U), including a frame, a lifting mechanism, and an operating platform. The frame can run on railway tracks. This tunnel working platform is designed to be secured to the railway rails via a through-slot, making the entire frame very stable in the horizontal direction and in the direction perpendicular to the rails, preventing it from tipping over and increasing the safety of high-altitude operations. However, this platform does not provide power, making relocation inconvenient and limiting its working range, as it cannot cover the entire inner wall of the tunnel.

[0007] An existing patent discloses a tunnel working platform vehicle (authorization number CN 207313066 U), which includes a transport vehicle and a working platform rotatably mounted on the transport vehicle; the working platform is equipped with multiple sets of platforms. This tunnel working platform vehicle can be deployed according to working conditions, can meet the construction needs of tunnels of various sizes, and can be flexibly moved between sites. However, this invention appears too complex for specific construction work, especially for some inspection and maintenance work, which is undoubtedly overkill, and the preparation work before and after use is quite cumbersome, making it inconvenient to use. Utility Model Content

[0008] This utility model provides a railway tunnel operation vehicle that can solve the problems of existing operation vehicles being inconvenient to relocate and unable to cover the operation area inside the tunnel.

[0009] A railway tunnel working vehicle includes a mobile chassis, a carriage, and a lifting platform installed inside the carriage;

[0010] The carriage is mounted on a mobile chassis via a slewing mechanism one, and the lifting platform is mounted inside the carriage via a slewing mechanism two. Under the action of the slewing mechanism one, the carriage can rotate around the slewing mechanism one, and under the action of the slewing mechanism two, the lifting platform can rotate around the slewing mechanism two.

[0011] Preferably, both the first slewing mechanism and the second slewing mechanism are slewing drive devices.

[0012] Preferably, it also includes a subframe, which is fixed to the rear of the mobile chassis, and the slewing mechanism is mounted on the subframe.

[0013] Preferably, the lifting work platform includes a work platform and a lifting column system, the bottom end of the lifting column system is connected to the second slewing mechanism, and the work platform is fixedly installed on the top of the lifting column system.

[0014] Preferably, the lifting column system is a multi-section telescopic sleeve structure.

[0015] Preferably, a ladder assembly is installed on any of the telescopic sleeve structures.

[0016] Preferably, a drive cylinder is installed on any of the telescopic sleeve structures described above.

[0017] Preferably, the workbench is surrounded by a fence.

[0018] Compared with existing technologies, the advantages of this utility model are as follows: This utility model achieves horizontal position changes of the working platform through rotating mechanism one and rotating mechanism two. Furthermore, by incorporating a lifting working platform, it achieves vertical position adjustment of the working platform, thus ensuring full coverage of the tunnel space. The entire machine has three degrees of freedom, simplifying operation. Additionally, the absence of fixed outriggers simplifies preparations such as dismantling before and after operation. This improves operational efficiency. Attached Figure Description

[0025] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0026] Example 1

[0027] like Figures 1 to 4 As shown in the figure, the railway tunnel working vehicle provided by this utility model includes a mobile chassis 1, a carriage 2 and a lifting working platform 6 installed in the carriage 2. The carriage 2 can be used to place maintenance tools, installation components, etc.

[0028] The carriage 2 is mounted on the mobile chassis 1 via a slewing mechanism 3, and the lifting platform 6 is mounted inside the carriage 2 via a slewing mechanism 4. Under the action of the slewing mechanism 3, the carriage 2 can rotate around the slewing mechanism 3 (360° rotation), and under the action of the slewing mechanism 4, the lifting platform 6 can rotate around the slewing mechanism 4 (360° rotation). The slewing mechanism 3 and the slewing mechanism 4 are driven by a slewing mechanism, which is an existing structure and will not be described in detail here.

[0029] Since the load-bearing capacity of the lifting platform 6 is generally not large during tunnel construction, and the overall layout of the machine can fully meet the stability requirements, the equipment does not need to be fixed during construction. After construction is completed at a certain location, it can be quickly moved to another location.

[0030] like Figure 2 As shown, when the work vehicle is located in the middle of the tunnel, it can carry out work in the area on both sides of the tunnel within the radius of the middle. The mobile chassis 1 facilitates the transfer of work sites and can carry out construction during the movement. The inner wall of the tunnel within the working radius can be covered by the slewing mechanism 1 3, and the working position can be adjusted by the slewing mechanism 2 4. The adjustment is also very convenient.

[0031] Example 2

[0032] like Figure 1 As shown, this embodiment proposes a railway tunnel working vehicle, which, based on the first embodiment, also includes a subframe 5. The subframe 5 is fixed to the rear of the mobile chassis 1, and a slewing mechanism 3 is installed on the central axis of the subframe 5 and close to the rear. The main function of the subframe 5 is to transfer the load above to the mobile chassis 1 more evenly.

[0033] Example 3

[0034] like Figure 4 As shown, this embodiment proposes a railway tunnel operation vehicle. Based on the first embodiment, its lifting operation platform includes a work platform 6 and a lifting column system. The bottom end of the lifting column system is connected to the rotary mechanism 4, and the work platform 6 is fixedly installed on the top of the lifting column system.

[0035] The lifting column system is a multi-section telescopic sleeve structure 7. A drive cylinder 8 is installed on the side of each telescopic sleeve structure 7. The drive cylinder 8 of each telescopic sleeve structure 7 is partially fixed to the telescopic sleeve structure 7 located below the telescopic sleeve structure 7 of that section. The drive cylinder 8 of the first telescopic sleeve structure 7 is installed on the base connected to the slewing mechanism 4. A work platform 6 is installed at the top of the last telescopic sleeve structure 7. The work platform 6 is surrounded by a fence 9. The fence 9 can be movable or fixed. The movable fence 9 can be laid flat and fixed to ensure the height of the whole vehicle when it is in motion. A ladder assembly 10 is also installed on each telescopic sleeve structure 7 of the lifting column system. The ladder assembly 10 can be extended and retracted with the lifting column system to facilitate the workers to climb onto the work platform 6.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
