Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel ring track sliding construction device. Background Technology

[0002] During tunnel construction, multiple non-excavation face operations often need to be completed within limited space. To improve work efficiency, some construction equipment uses a ring-rail sliding mechanism, enabling the working device to move circumferentially along a ring rail, thereby achieving large-scale construction coverage. However, this type of equipment generally relies on a hydraulic system for power, and the layout of the hydraulic pipelines directly affects the normal operation of the sliding trolley and the working device.

[0003] In existing technologies, hydraulic lines are typically laid out using cable chains. While this method can constrain the direction of the lines to some extent and prevent uncontrolled dragging, it has significant limitations in ring track sliding applications. Due to the narrow space inside tunnels, cable chain installation often requires a large amount of space, which is difficult to meet in actual construction environments. When the sliding trolley has a large range of motion, the cable chain needs to have even greater allowance, resulting in complex structures and difficult layout. Utility Model Content

[0004] This utility model provides a tunnel ring track sliding construction device to solve the technical problem that the ring track sliding mechanism occupies a large space when using drag chain to arrange hydraulic pipelines during tunnel construction.

[0006] Optionally, the outlet window is located at the midpoint of the sliding trolley's travel.

[0007] Optionally, the hydraulic hose reel includes a reel body and a central shaft. The reel body and the central shaft are rotatably coupled, and the hydraulic lines are wound on the reel body. The central shaft is provided with a rotary joint and a fixed end port. The rotary joint is connected to the hydraulic lines, and the fixed end port is connected to the working device. The central shaft is provided with a channel connecting the rotary joint and the fixed end port.

[0008] Optionally, a spring is provided between the central shaft and the reel body to provide torque to drive the reel body to rotate and wind up the hydraulic lines.

[0016] This application addresses the issue of hydraulic pipelines being drawn out by installing a hydraulic pump station on the chassis and creating an outlet window along the pipeline path between the pump station and the sliding trolley. This design limits the direction of the hydraulic pipeline's exit, preventing it from extending haphazardly in confined spaces. Simultaneously, a hydraulic hose reel is installed on the sliding trolley to wind the hydraulic pipeline, allowing it to automatically wind up and down as the reel rotates during the trolley's circumferential movement. One end of the hydraulic pipeline connects to the hydraulic pump station through the outlet window, while the other end connects to the working device on the trolley. This not only ensures reliable transmission of hydraulic power but also effectively shortens the required pipeline length through the reel's winding and unwinding function, significantly reducing the space needed for pipeline installation. This structure comprehensively utilizes the synergistic effect of the hydraulic pump station, outlet window, and hose reel to solve the problems of large space occupation and poor adaptability associated with cable chain installations in tunnel construction.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a tunnel ring track sliding construction device.

[0026] Reference Figure 1 This embodiment provides a tunnel ring track 3 sliding construction device, which includes a frame 1, a hydraulic pump station 2, a ring track 3, a sliding trolley 4, a working device 5, a hydraulic hose reel 6, and hydraulic pipelines 8. The frame 1 serves as the basic support and installation component, providing load-bearing and fixing functions. The hydraulic pump station 2 is fixedly installed on the frame 1 to provide hydraulic power to the entire device. The ring track 3 is provided with a pipe outlet window, through which the hydraulic pipelines 8 can be led out and fixed, ensuring that hydraulic oil is smoothly delivered from the pump station to the sliding mechanism. The window also limits the direction of the pipelines, preventing them from extending disorderly in narrow spaces.

[0027] The circular rail 3 is fixedly installed on the frame 1, serving as the running track for the sliding trolley 4, enabling the trolley 4 to move circumferentially. The sliding trolley 4 is mounted on the circular rail 3 and fixedly connected to the working device 5, which completes circumferential operations within the tunnel under the guidance of the circular rail 3. To address the issues of inconvenient arrangement and excessive space occupation of the hydraulic pipeline 8 when it moves extensively with the sliding trolley 4, this embodiment installs a hydraulic hose reel 6 on the sliding trolley 4 for automatic retraction and extension of the hydraulic pipeline 8. One end of the hydraulic pipeline 8 is connected to the hydraulic pump station 2 through an outlet window, and the other end is connected to the hydraulic components of the working device 5 mounted on the sliding trolley 4, thereby ensuring continuous power transmission while preventing excessive stretching or accumulation of the pipeline due to movement.

[0028] Through the above structural design, this embodiment effectively solves the problems of excessive space occupation, installation difficulties, and insufficient operational reliability of traditional cable carrier piping methods in tunnel construction equipment. The outlet window limits the direction of the hydraulic pipeline 8, allowing the pipeline to move within a controlled path and reducing unnecessary space occupation; the hydraulic hose reel 6 replaces the cable carrier for winding and unwinding, significantly shortening the reserved length of the pipeline. This not only saves limited layout space inside the tunnel but also improves the stability and reliability of pipeline operation, ensuring efficient construction of the equipment under complex working conditions.

[0029] In one embodiment, the ring rail 3 is fixedly mounted on the frame 1, and has an arc-shaped or annular guide rail structure to provide a continuous movement path for the sliding trolley 4. The sliding trolley 4 and the ring rail 3 are connected by multiple sets of rollers, which are arranged symmetrically up and down or left and right, allowing the trolley to run closely along the ring rail 3. This ensures smooth sliding of the trolley along the track and prevents it from derailing or wobbling during movement. The drive mechanism of the sliding trolley 4 adopts a rack and pinion transmission. A rack is provided on the inner or outer side of the ring rail 3, and a drive gear meshing with it is installed on the trolley. The drive gear is connected to the output shaft of a hydraulic motor. When the hydraulic motor operates, the meshing of the drive gear and the rack drives the trolley to move along the ring rail 3. The rack and pinion transmission method has the advantages of compact structure and high transmission efficiency, enabling precise control of the trolley's speed and position, and is particularly suitable for the stable operation requirements in tunnel construction environments. Limit switches or mechanical stops can be installed at both ends of the trolley to detect the extreme positions of the trolley's travel and prevent it from overtraveling or colliding. Additionally, buffers or vibration damping elements can be installed at the bottom of the trolley to decelerate and absorb impacts when the trolley approaches the end of its travel, improving safety and stability during movement. Since the working device 5 is directly mounted on the sliding trolley 4, and the hydraulic hose reel 6 is also fixedly connected to the trolley, the sliding trolley 4 not only performs the motion function but also provides load-bearing and positioning. During trolley operation, the working device 5 remains fixed relative to the trolley, and the hydraulic lines 8 adapt to the trolley's displacement through the automatic reel's winding and unwinding, thus ensuring the coordinated operation of the entire ring track 3 sliding system.

[0030] In one embodiment, the outlet window on the frame 1 is positioned at the midpoint of the travel of the sliding trolley 4. For example, in this embodiment, the sliding trolley 4 travels 170° on the ring track 3, so the outlet window is positioned at approximately 85°, exactly at the midpoint of its travel. If the window is positioned to one side, the hydraulic line 8 would require an additional length when moving in the opposite direction, resulting in an increase in the diameter and overall size of the hydraulic hose reel 6, making the device layout difficult. By positioning the outlet window at the midpoint, the travel distance of the sliding trolley 4 on both sides remains symmetrical, and the maximum extension and minimum retraction of the hydraulic line 8 within the entire 170° travel range are reasonably controlled, with the reserved length optimized to the theoretical minimum. As a result, the size of the hydraulic hose reel 6 is significantly reduced, the design and manufacturing difficulty is lowered, and the limited layout space inside the tunnel is effectively saved. More importantly, this arrangement ensures that the pipeline is subjected to uniform force on both sides during reciprocating motion, avoiding damage caused by excessive stretching or local bending, thereby improving the operational stability and service life of the hydraulic system.

[0031] Reference Figure 2 In one embodiment, the hydraulic hose reel 6 includes a reel body 9 and a central shaft 10. The reel body 9 and the central shaft 10 are rotatably coupled, and the hydraulic pipeline 8 is spirally wound around the outer circumference of the reel body 9. To ensure continuous delivery of hydraulic oil during the reel's rotation and unwinding process, the central shaft 10 is equipped with a rotary joint 11 and a fixed end port 12. The rotary joint 11 is connected to the wound hydraulic pipeline 8, and the fixed end port 12 is connected to the working device 5 on the sliding trolley 4. A channel is provided inside the central shaft 10 to connect the rotary joint 11 and the fixed end port 12, allowing the hydraulic oil to flow smoothly under different rotational states. Through this internal channel design, the continuous supply of hydraulic oil is not affected during the rotation of the reel body 9, thereby ensuring the stable operation of the working device 5.

[0032] In addition, a pre-tension spring 13 is provided between the central shaft 10 and the reel body 9. One end of the spring 13 is fixed to the central shaft 10, and the other end is connected to the reel body 9, providing torque during the pulling and retraction of the pipeline. When the sliding trolley 4 moves away from the outlet window, the hydraulic pipeline 8 is pulled out, and the reel body 9 rotates clockwise under the pulling force to release the pipeline; when the sliding trolley 4 moves closer to the outlet window, the pre-tension spring 13 releases its stored energy, driving the reel body 9 to rotate counterclockwise, thereby automatically retracting the hydraulic pipeline 8. In this way, the hydraulic pipeline 8 can be automatically retracted and extended throughout its entire stroke range, avoiding tangling due to excessive slack and excessive stress concentration due to insufficient tension. Through this reel structure design, the hydraulic pipeline 8 retraction and extension process achieves a high degree of automation and reliable control, avoiding pipeline damage caused by insufficient space or excessive stroke in traditional cable chain arrangements, and greatly improving the stability and lifespan of the system.

[0033] In this embodiment, the hydraulic hose reel 6 is connected to the sliding trolley 4 via the fixed end of the central shaft 10. The central shaft 10 has a fixed end and a rotating end at its two ends. The fixed end is reliably fixed to the main structure of the trolley, which can be achieved by bolt connection or bracket embedding, ensuring that the fixed end of the central shaft 10 remains stationary during trolley movement. The reel body 9 rotates around the central shaft 10, thereby enabling the winding and unwinding of the hydraulic lines 8. Because the fixed end of the central shaft 10 is rigidly connected to the trolley, the rotary joint 11 in the hydraulic system can be positioned at the fixed end, allowing hydraulic oil to enter the internal channel of the central shaft 10 through the fixed end port 12, and then be delivered to the lines wound on the reel via the rotating end, ensuring stable flow of hydraulic oil during reel rotation. This connection via the fixed end of the central shaft 10 to the trolley avoids shaking or displacement of the reel during trolley movement, improving the stability of the reel winding and unwinding lines and simplifying the installation structure. Meanwhile, the rotation of the reel and the sliding motion of the trolley are independent of each other, and the extension and retraction of the pipeline are entirely achieved by the reel and spring 13, which will not affect the normal movement of the trolley, thus ensuring the overall coordination and reliability of the device.

[0034] In one embodiment, two sets of sliding trolleys 4 and working devices 5 are symmetrically arranged on the ring rail 3, respectively installed on the left and right sides of the ring rail 3. Each set of sliding trolleys 4 is equipped with an independent hydraulic hose reel 6 for controlling the extension and retraction of its respective hydraulic lines 8, enabling the two sets of working devices 5 to operate independently without interference. This symmetrical arrangement not only expands the overall construction coverage area but also improves the working efficiency of the ring rail 3 sliding mechanism.

[0035] To prevent interference between the two hydraulic hoses during deployment and retraction, this embodiment designs the two hydraulic hose reels 6 with opposite rotation directions. Specifically, when the left sliding trolley 4 moves, its hydraulic line 8 is pulled out or retracted in the direction of the reel's rotation; while the right sliding trolley 4's reel rotates in the opposite direction, causing the two lines to extend in different directions during operation, ensuring that the lines are separated and effectively avoiding the risk of entanglement or collision. This symmetrical and oppositely rotating reel design ensures that the stability and safety of the line movement are maintained even when both working devices 5 are operating simultaneously.

[0036] Furthermore, the travel distances of the two sliding trolleys 4 on the ring track 3 are partially overlapped. This travel distance design ensures that the working ranges of the two working devices 5 overlap, eliminating any gaps in the entire construction area. In actual tunnel construction, the overlapping travel distances allow the two working devices 5 to work together in the intersection area, avoiding blind spots caused by the limited travel distances of the working devices 5, thereby improving the continuity and integrity of the overall operation.

[0037] In one embodiment, the hydraulic pump stations 2 are arranged symmetrically, with one independent hydraulic pump station 2 on each side of the chassis 1. Each hydraulic pump station 2 provides hydraulic power to the corresponding sliding trolley 4 and its working device 5, thereby achieving symmetrical and independent power distribution. This arrangement not only ensures that the two sets of working devices 5 do not interfere with each other when operating simultaneously, but also ensures that if one pump station fails, the other pump station and its working device 5 can still operate normally, improving the system's redundancy and overall reliability. The hydraulic pump stations 2 are connected to the hydraulic hose reels 6 through their respective outlet windows. The hydraulic oil is delivered to the working device 5 after passing through the reel's rotary joint 11, achieving continuous power transmission. Since the pump stations and working devices 5 are one-to-one, the hydraulic pipeline 8 is arranged more simply, avoiding intersections and interference, enabling the system to maintain efficient and stable operation even in the narrow space of a tunnel.

[0038] In one embodiment, a pipe baffle 7 is provided between the frame 1 and the sliding trolley 4 to limit and protect the routing of the hydraulic pipes 8. The position of the pipe baffle 7 corresponds to the guide groove of the hydraulic hose reel 6, ensuring that the hydraulic pipes 8 always move in a fixed direction during the winding and unwinding process, avoiding lateral swaying or bending, thereby reducing damage caused by lateral forces. The pipe outlet window on the frame 1 is opened on this baffle, allowing the hydraulic pipes 8 to be smoothly led out from the hydraulic pump station 2 under the guidance of the baffle, which not only serves a fixing function but also ensures the controllability of the pipe movement.

[0039] The hydraulic hose reel 6 is preferably fixed above the sliding trolley 4. This arrangement ensures that when the sliding trolley 4 reaches its lowest limit position, there is no interference between the reel and the bottom of the frame 1, preventing damage to the reel or hose from collisions. Furthermore, the top mounting facilitates future inspection and maintenance, reduces the chance of the hose coming into contact with ground obstacles, and improves overall reliability.

[0040] Furthermore, to further reduce the risk of pipeline damage, this embodiment designs the contact area of ​​the hydraulic pipeline 8 between the pipeline partition 7 and the hydraulic hose reel 6 with a rounded corner or smooth transition structure. When the hydraulic pipeline 8 moves repeatedly under the reel's winding and unwinding action, it avoids wear or scratching from sharp edges, thereby extending the pipeline's service life. This detailed design plays a crucial role in improving the long-term stability of equipment operation. Through the above structural design, this embodiment not only achieves a reasonable arrangement of the hydraulic pipeline 8 within a confined space, but also improves the adaptability and reliability of the pipeline under large-scale movement through measures such as partition guidance, installation above the reel, and rounded corner protection, further ensuring the stable operation of tunnel construction equipment under complex working conditions.

[0041] In this embodiment, the hydraulic hose reel 6 is designed with strong adaptability and scalability. The length of the hose wound on the reel is not fixed but can be flexibly adjusted according to the actual construction conditions. When tunnel construction requires a larger circumferential operation, simply replacing or lengthening the moving part of the hydraulic hose 8 on the reel can expand the operating range of the sliding trolley 4, thereby meeting the requirements of different construction radii or construction coverage areas without changing the overall structure. Conversely, when the construction space is limited or the operating range is small, a shorter hydraulic hose 8 can be used to reduce the reel diameter and overall size, thereby reducing the space occupied. Through this adjustable hose length, the reel system can adapt to various tunnel construction projects of different scales, significantly improving the system's flexibility and versatility. In addition, this reel arrangement scheme is not only applicable to the winding and unwinding of the hydraulic hose 8 but can also be extended to the automatic arrangement of electrical lines. For example, in situations where power or signal transmission is required for the working device 5, the same reel structure can be used to wind the cable in an orderly manner, and continuous transmission of power and signals can be achieved through the rotary joint 11 or slip ring device. In this way, the cable can be automatically retracted and extended when the sliding trolley 4 makes a large-scale circumferential movement, avoiding damage caused by dragging or entanglement. This application expansion not only ensures the efficient operation of the hydraulic system, but also provides a safe and reliable wiring method for the electrical system.

[0042] Through the above improvements, the hydraulic hose reel 6 solution of this embodiment can be widely applied to tunnel construction equipment and other types of ring track 3 sliding mechanisms. Whether for hydraulic power transmission or electrical wiring layout, this reel structure can achieve automatic winding and effective protection within confined spaces, thereby overcoming the limitations of traditional fixed pipe laying or cable chain layout methods in terms of space occupation, range of motion, and reliability. It has high engineering practical value and promising prospects for widespread application.

[0043] The working device 5 mounted on the sliding trolley 4 can be configured according to different tunnel construction procedures, exhibiting strong adaptability. For example, the working device 5 can be a shotcrete robotic arm for concrete spraying reinforcement of the tunnel walls; it can also be a drilling device for anchor bolt construction to reinforce the surrounding rock of the tunnel; or it can be a cutting or milling device for cleaning and trimming the tunnel interior walls. When it is necessary to install air ducts, cables, or pipelines, the working device 5 can also employ a hoisting and installation mechanism to achieve material handling and fixing. In addition, the working device 5 can also be a measuring and detection device, such as a laser rangefinder or geological detection sensor, for real-time monitoring of the structural parameters and safety status of the tunnel construction environment. By adopting different forms of working devices 5, the sliding working device 5 of the ring track 3 provided by this invention can meet the multi-stage and multi-functional operational needs in the trenchless tunnel construction process.

[0044] The implementation principle of the tunnel ring track 3 sliding construction device in this application embodiment is as follows: The hydraulic pump station 2 is installed on the frame 1 as the system power source, and outputs hydraulic oil to the hydraulic hose reel 6 through the outlet window; the hydraulic hose reel 6 is installed on the sliding trolley 4, and has a central shaft 10, a rotary joint 11 and a spring 13 inside. The hydraulic oil is delivered to the hydraulic components of the working device 5 through the rotary joint 11. When the sliding trolley 4 moves circumferentially along the ring track 3, the hydraulic pipeline 8 is automatically extended and retracted according to the position of the trolley under the action of the reel. When the trolley moves away from the outlet window, the hydraulic pipeline 8 is pulled out, and the reel rotates clockwise under the action of the tension to release the hose; when the trolley moves closer to the outlet window, the reel rotates counterclockwise under the action of the torque of the spring 13 to retract the hose, thereby realizing the dynamic adjustment of the hydraulic pipeline 8 within the entire stroke range. By installing a pipe baffle 7 between the frame 1 and the sliding trolley 4 and opening a pipe outlet window on the ring rail, the direction of the hydraulic pipeline 8 is fixed and constrained, preventing lateral swaying or interference with other components during the winding and unwinding process. The baffle is arranged correspondingly to the reel guide groove, ensuring that the pipeline always moves along the predetermined path and reducing the risk of wear. For the structure of the dual working device 5, the two sliding trolleys 4 are symmetrically arranged on the ring rail 3, each equipped with an independent hydraulic hose reel 6, and the reels rotate in opposite directions, so that the pipelines on the left and right sides do not interfere with each other when running simultaneously. Since the stroke of the two sliding trolleys 4 has an overlapping section, coverage and continuous operation can be achieved in the boundary area of ​​the construction range. Automatic winding and unwinding and controlled guidance of the hydraulic pipeline 8 are realized under the sliding condition of the ring rail 3 of the tunnel construction equipment, thereby solving the problems of large space occupation, difficulty in reservation, and insufficient reliability of the traditional drag chain arrangement method, and ensuring the stability and efficiency of the equipment in a confined construction space.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
