Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a rail-mounted inspection vehicle. Background Technology

[0002] A monorail system is a system that uses a specially made I-beam suspended above a tunnel as a track. Various types of lifting vehicles are connected together to form a train, which is then pulled along the track by traction equipment. The traction power can be provided by wire ropes, diesel engines, batteries, or pneumatic devices.

[0003] With the increasing intelligence of tunnel excavation, monorail cranes are being used more and more widely. When using monorail cranes, tracks must be laid. In order to speed up the completion and put them into use, the track beams must be installed quickly and accurately.

[0004] However, the existing track installation is mainly done manually, which is labor-intensive, inefficient, and poses significant safety hazards, thus limiting the speed of monorail crane track installation.

[0005] Therefore, the existing technology still needs further development. Utility Model Content

[0006] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a rail-mounted track installation and inspection vehicle to solve the technical problem that the installation of tracks still requires manual installation in the existing technology.

[0007] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: a rail-mounted inspection vehicle is provided, comprising: a transport platform for mounting on a track fixed above a roadway, the transport platform being movably mounted relative to the track along a preset track path; the transport platform having an activity space; the activity space for storing track segments to be installed and providing an activity area for operators; an operating platform located on the side of the transport platform near the end of the current track segment, the operating platform being connected to the transport platform and its position adjustable relative to the transport platform; the operating platform having an operating space connected to the activity space, allowing operators to move between the activity space and the operating space.

[0011] Furthermore, the rail-mounted inspection vehicle also includes: a first connector extending along a preset arc trajectory, having multiple first connecting holes spaced apart along its extension direction, one end of the first connector connected to a connecting platform, and the other end facing the operating platform body; a second connector on the side of the operating platform body near the connecting platform, protruding from the operating platform body and positioned opposite to the first connector; a second connecting hole fitted to any one of the multiple first connecting holes; and a locking member for connecting to the second connecting hole and any one of the multiple first connecting holes; wherein, when the operating platform body rotates relative to the connecting platform to a target angle, one of the multiple first connecting holes is positioned opposite to the second connecting hole, and the locking member passes through the first connecting hole and the second connecting hole in sequence to lock the operating platform body to the connecting platform.

[0012] Furthermore, the operating platform includes: an operating platform body having an operating space; an anchor bolt drilling machine mounted on the operating platform body, with at least a portion of the anchor bolt drilling machine located within the operating space; the anchor bolt drilling machine is used for drilling holes in the roof of the roadway.

[0013] Furthermore, the operating platform also includes a hoist, which is installed on the operating platform body and located within the operating space. The hoist is used to lift the track section to be installed to a preset height. The hoist and the anchor drilling machine are spaced apart along the length of the operating platform body.

[0014] Furthermore, the transportation platform includes: a transportation platform body with an active space; a traveling mechanism for being mounted on a track fixed above the tunnel, the traveling mechanism being movable relative to the track along a preset track path; the transportation platform body is mounted on the connecting end of the traveling mechanism to drive the transportation platform body to move.

[0015] Furthermore, the transport platform body has a clearance opening on its load-bearing plate for avoiding the track section; the transport platform also includes a hoisting device, which is installed in the activity space, and the hoisting part of the hoisting device can hoist the track section located on the ground into the activity space for storage through the clearance opening.

[0016] Furthermore, the rail-mounted inspection vehicle also includes: a drive unit for mounting on a track fixed above the roadway, the drive unit being movably mounted relative to the track along a preset track path; the drive unit being driven to connect with a transport platform to drive the transport platform to move; and / or, a support device movably mounted at the bottom of the operating platform, the support device having a clearance state and a support state; when the operating platform is in a moving state, the support device is in a clearance state to avoid the roadway floor; when the operating platform moves to the target position, the support device is in a support state, the support device contacting the roadway floor to support the operating platform.

[0017] Beneficial effects: This utility model provides a rail-mounted installation and inspection vehicle, comprising: a transport platform and an operating platform. The transport platform is mounted on a track fixed above a tunnel and is movably positioned relative to the track along a preset track path. The transport platform has a working space for storing track segments to be installed and providing an area for operators. The operating platform is located on the side of the transport platform near the end of the current track segment (i.e., the end of each track segment closest to the next segment). The operating platform is connected to the transport platform, allowing it to move along the preset track path via the transport platform. The operating platform also has an operating space for operators to perform track installation, joint tightening, equipment inspection, and maintenance. The operating space is connected to the working space, facilitating free movement of operators between the two spaces. Furthermore, when track installation is required, operators can easily move track segments from the working space to the operating space for positioning and assembly. At the same time, the operating platform is positioned relative to the transport platform in an adjustable manner, so that the operating platform can be adjusted in multiple degrees of freedom according to the preset work trajectory or working condition requirements. This allows the operating platform to be flexibly positioned within the space to adapt to the needs of different track docking angles, installation heights or inspection work points.

[0018] Therefore, by setting up a transportation platform and an operating platform, track transportation, personnel carrying, installation operation, and inspection functions can be integrated into one, realizing continuous operation throughout the entire process of "transportation—handling—installation—inspection." This significantly reduces the time lost from multiple disassemblies and relocations of equipment in traditional operations, and significantly improves the efficiency of track installation and maintenance. Furthermore, the interconnected design of the activity space and operating space allows operators to move seamlessly between the transportation and work areas without frequent boarding and alighting or crossing obstacles, reducing labor intensity and safety risks. Simultaneously, track segments are stored nearby in the activity space for easy access, avoiding long-distance transport. Meanwhile, placing the operating platform on the side of the transportation platform near the end of the current track segment ensures that the operating platform faces the next installation position, allowing operators to perform track docking, calibration, and tightening from the optimal working position, improving installation accuracy and connection reliability, and reducing quality problems such as misalignment and skewness. Moreover, the adjustable design of the operating platform allows it to dynamically adjust according to changes in track direction, connection deviations, or tunnel space, effectively adapting to complex and changing installation environments and avoiding alignment difficulties or blind spots caused by rigid structural fixation. With multi-directional adjustment functions, such as adjusting the vertical pitch angle and horizontal bending angle, the operating platform can be precisely moved to the target installation position, ensuring high-precision docking between the track section to be installed and the existing track. This design significantly reduces the workload and time of manual calibration, improving installation efficiency and connection reliability. Furthermore, all operations are carried out on a stable platform fixed to the track, avoiding the risks of personnel working suspended at heights or in confined spaces. The transport platform and operating platform move synchronously, supporting continuous operation, reducing downtime, and improving overall operational continuity and safety. Moreover, by integrating the transport platform with the adjustable operating platform, automatic transport, precise positioning, and on-site assembly of track sections are achieved, significantly reducing reliance on manual handling and high-altitude operations, and promoting the mechanization and automation of track installation. Additionally, this rail-mounted track installation inspection vehicle can move continuously along the track, and in conjunction with the multi-degree-of-freedom adjustment function of the operating platform, it achieves a "transport, dock, and install simultaneously" assembly line operation mode, avoiding redundant processes such as frequent downtime and redeployment of the operating platform in traditional methods, significantly improving overall installation speed and operational continuity. The rail-mounted track installation and inspection vehicle of this invention can effectively solve the technical problem that the installation of tracks still requires manual labor in the existing technology.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1 to 5According to an embodiment of this utility model, a rail-mounted track installation and inspection vehicle is provided, comprising: a transport platform 1 and an operating platform 2. The transport platform 1 is used to be set on a track fixed above a roadway, and the transport platform 1 is movably set relative to the track along a preset track path. The transport platform 1 has an activity space 10. The activity space 10 is used to store the track segment 100 to be installed and to provide an activity area for the operator. The operating platform 2 is located on the side of the transport platform 1 near the end of the current track segment 100. The operating platform 2 is connected to the transport platform 1, and the position of the operating platform 2 relative to the transport platform 1 is adjustable. The operating platform 2 has an operating space 20, which is connected to the activity space 10, so that the operator can move between the activity space 10 and the operating space 20.

[0023] As can be seen, the rail-mounted track installation and inspection vehicle provided by this utility model includes: a transport platform 1 and an operating platform 2. The transport platform 1 is used to be set on a track fixed above the tunnel, and the transport platform 1 is movably set relative to the track along a preset track path. The transport platform 1 is provided with an activity space 10, which is used to store the track segment 100 to be installed and to provide an activity area for operators. The operating platform 2 is located on the side of the transport platform 1 near the end of the current track segment 100 (i.e., the end of each track segment 100 near the next track segment 100). The operating platform 2 is connected to the transport platform 1 so that the transport platform 1 can drive the operating platform 2 to move along the preset track path. The operating platform 2 is provided with an operating space 20, in which operators can perform track installation, joint tightening, equipment inspection and maintenance and other procedures. The operating space 20 is connected to the activity space 10, allowing operators to move freely between the two spaces. When track installation is required, it facilitates the movement of track segments 100 from the activity space 10 to the operating space 20 for positioning and assembly. Simultaneously, the operating platform 2 is adjustable relative to the transport platform 1, enabling it to adjust its position with multiple degrees of freedom according to preset work trajectories or operational requirements. This allows the operating platform 2 to be flexibly positioned within the space to accommodate different track docking angles, installation heights, or inspection points.

[0024] Therefore, by setting up transport platform 1 and operating platform 2, the functions of rail transport, personnel carrying, installation operation, and inspection can be integrated into one, realizing continuous operation of the entire process of "transportation-handling-installation-inspection". This significantly reduces the time loss caused by multiple disassemblies and transfers of equipment in traditional operations, and significantly improves the efficiency of rail installation and maintenance. Furthermore, the interconnected design of the activity space 10 and operating space 20 allows operators to move seamlessly between the transport and work areas without frequent boarding and alighting or crossing obstacles, reducing labor intensity and safety risks. Meanwhile, the rail segment 100 is stored nearby in the activity space 10 for easy access, avoiding long-distance transport. At the same time, placing the operating platform 2 on the side of transport platform 1 near the end of the current rail segment ensures that the operating platform 2 faces the next installation position, allowing operators to perform rail docking, calibration, and tightening from the optimal working position, improving installation accuracy and connection reliability, and reducing quality problems such as misalignment and skewness. Furthermore, the adjustable design of the operating platform 2 allows it to dynamically adjust according to changes in track alignment, connection deviations, or tunnel space, effectively adapting to complex and ever-changing installation environments and avoiding alignment difficulties or blind spots caused by rigid structural fixation. Through multi-directional adjustment functions, such as adjusting the vertical pitch angle and horizontal bending angle, the operating platform 2 can precisely move to the target installation position, ensuring high-precision docking of the track segment 100 to be installed with the existing track. This design significantly reduces the workload and time required for manual calibration, improving installation efficiency and connection reliability. In addition, all operations are performed on a stable platform fixed to the track, avoiding the risks of personnel working suspended at heights or in confined spaces. The transport platform moves synchronously with the operating platform, supporting continuous operation, reducing downtime, and improving overall operational continuity and safety. Moreover, by integrating the transport platform 1 with the adjustable operating platform 2, automatic transport, precise positioning, and on-site assembly of track segments are achieved, significantly reducing reliance on manual handling and high-altitude operations, and promoting the mechanization and automation of track installation. Furthermore, this rail-mounted track installation and inspection vehicle can move continuously along the track. Combined with the multi-degree-of-freedom adjustment function of the operating platform 2, it achieves a streamlined operation mode of "transporting, docking, and installing simultaneously," avoiding redundant processes such as frequent machine stops and redeployment of the operating platform in traditional methods. This significantly improves the overall installation speed and operational continuity. The rail-mounted track installation and inspection vehicle of this invention effectively solves the technical problem that existing technologies still require manual installation of tracks.

[0025] The “preset track path” mentioned above refers to the track extension route that is planned and fixed in advance within the tunnel, based on the structural characteristics of the tunnel or the needs of the inspection task.

[0026] In actual operation, several track sections 100 are first pre-installed above the tunnel using a ground installation vehicle. Then, a rail-mounted inspection vehicle is attached to these sections for subsequent track installation. Preferably, three track sections 100 are installed first.

[0027] Specifically, such as Figures 1 to 5 As shown, the rail-mounted inspection vehicle also includes: a connecting platform 3, located between the operating platform 2 and the transport platform 1, connected to both the transport platform 1 and the operating platform 2, and rotatably mounted relative to the transport platform 1 in the vertical direction; the operating platform 2 is rotatably mounted relative to the connecting platform 3 in an axis parallel to the width direction of the connecting platform 3; the connecting platform 3 has a connecting space 30, which connects to both the moving space 10 and the operating platform 2. This structural arrangement, through the horizontal rotation of the connecting platform 3 and the pitch rotation of the operating platform 2, enables the operating platform 2 to be adjusted within space, allowing it to accurately align with rail connection points of different directions, slopes, or heights, effectively handling complex working conditions such as tunnel turns and ramp connections, significantly improving the equipment's environmental adaptability. Simultaneously, the connecting space 30 ensures physical connectivity between the moving space 10 and the operating space 20, facilitating safe passage for operators between the transport and work areas, supporting the translation of rail sections, reducing handling resistance and time loss, and improving material flow efficiency. Furthermore, the connecting platform 3, serving as a transitional structure between the transport platform 1 and the operating platform 2, bears and transmits loads, effectively dispersing stress and improving the overall structural rigidity and operational stability. Simultaneously, as a motion hub, it coordinates rotation and pitch movements, avoiding motion interference and ensuring the coordinated operation of all components.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the transport platform 1 includes a transport platform body 11, and the connecting platform 3 is rotatably arranged relative to the transport platform body 11 about the vertical direction; the operating platform 2 includes an operating platform body 21, and the operating platform body 21 is rotatably arranged relative to the connecting platform 3 about an axis parallel to the width direction of the connecting platform 3.

[0029] Furthermore, such as Figures 1 to 3 As shown, the connecting platform 3 includes two first guardrails 31, a first base plate 32, and a first connecting frame 33. The two first guardrails 31 are symmetrically arranged on the first base plate 32, and are spaced apart along the width direction of the connecting platform 3. The first connecting frame 33 is installed on the top of the two first guardrails 31 and connects the two first guardrails 31 respectively. The two first guardrails 31, the first base plate 32, and the first connecting frame 33 form a communicating space 30.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the transport platform 1 includes a transport platform body 11, which has an active space 10. The top and bottom of the transport platform body 11 are hinged to the top and bottom of the connecting platform 3, respectively. The rail-mounted track installation and inspection vehicle also includes a first telescopic mechanism 4, which is located at the bottom of the transport platform body 11. The fixed end of the first telescopic mechanism 4 is installed at the bottom of the transport platform body 11, and the free end of the first telescopic rod 41 of the first telescopic mechanism 4 is rotatably connected to the bottom of the connecting platform 3. The telescopic direction of the first telescopic rod 41 forms a first preset angle with the length direction of the transport platform body 11. The first preset angle is greater than 0° and less than 90°. Through the telescopic movement of the first telescopic mechanism 4, an oblique force is generated, driving the connecting platform 3 to rotate relative to the transport platform body 11 in the horizontal plane around the vertical axis, and driving the operating platform 2 to rotate synchronously. This structure enables the operating platform to actively turn at the curve of the track, ensuring that it is always aligned with the extension direction of the track to be installed, thereby effectively completing continuous installation operations under turning conditions.

[0031] By adopting the above-mentioned structural configuration, the oblique arrangement and telescopic movement of the first telescopic mechanism 4 drives the connecting platform 3 to rotate in the horizontal plane relative to the transport platform 1. This allows the operating platform 2 to actively adjust its orientation and precisely align with the track installation direction on curves or changing sections, solving the alignment difficulties caused by the structural rigidity of traditional equipment when operating on curves. Furthermore, as the rail-mounted track installation inspection vehicle travels along curved tracks, the first telescopic mechanism 4 can adjust the azimuth angle of the operating platform 2 in real time, ensuring it always faces the next installation point without needing to stop and reposition. This achieves a continuous operation mode of "adjusting while moving and installing while adjusting," significantly improving installation efficiency. In addition, this design enables the rail-mounted track installation inspection vehicle to adapt to various track configurations, including straight sections, gentle curves, and even sharp curves, making it widely applicable to complex scenarios such as underground alleyways, tunnels, and elevated tracks, significantly improving the equipment's versatility and engineering applicability.

[0032] Furthermore, such as Figures 1 to 3As shown, the transport platform body 11 includes: a support plate 111, two second guardrails 112, a third guardrail 113, and two second connecting brackets 114. The two second guardrails 112 are mounted on the support plate 111 and are arranged opposite to each other, spaced apart along the width direction of the transport platform body 11. The third guardrail 113 is mounted on the support plate 111, located between the two second guardrails 112, and is located on the side of the support plate 111 away from the connecting platform 3. The third guardrail 113 is connected to both second guardrails 112. The two second connecting brackets 114 are spaced apart along the length direction of the transport platform body 11, and each second connecting bracket 114 is connected to the top of one of the two second guardrails 112. One of the two second guardrails 112 has an entrance / exit 115 to facilitate personnel entering the activity space 10. The activity space 10 is enclosed by the support plate 111, two second guardrails 112 and a third guardrail 113.

[0033] Among them, the second connecting bracket 114 on the side closer to the connecting platform 3 is hinged to the first connecting frame 33, and the bearing plate 111 is hinged to the first base plate 32, so that the connecting platform 3 and the transport platform body 11 can rotate relative to each other, thereby realizing horizontal rotation.

[0034] Furthermore, a protective rope 116 is installed at the entrance / exit 115. Both ends of the protective rope 116 are detachably attached to the fixed structures on both sides of the entrance / exit 115. This protective rope 116 forms a temporary barrier around the entrance / exit 115 when operators enter the activity space 10, preventing accidental falls or the falling of tools and parts, thus improving operational safety. Simultaneously, its detachable structure allows for quick disassembly or reinstallation when operators need to enter or exit, balancing safety protection with operational convenience.

[0035] Optionally, the protective rope 116 is the first chain.

[0036] Furthermore, a climbing ladder 117 is provided at the entrance / exit 115. The climbing ladder 117 is retractable, and one end of the climbing ladder 117 is rotatably mounted on the support plate 111 near the entrance / exit 115. Through the combined movement of rotation and retraction, the climbing ladder 117 can switch between a stored state and a used state.

[0037] Optionally, when the inspection vehicle is parked at the work position on the rail-mounted installation and personnel need to get on and off, the operator rotates the climbing ladder 117 downwards around its rotation connection point, extending it from the storage position on the side wall of the transport platform body 11 to ground or platform height. Then, the ladder is pulled out and locked step by step via the telescopic structure until its upper and lower ends are securely abutting against the ground (or platform) and the support plate 111, forming a stable and safe passage. Personnel can use this ladder to safely ascend and descend the transport platform, enter the activity space 10 to perform work tasks, or exit from the activity space 10.

[0038] When the operator enters the activity space 10 to perform the work task, the operator will retract the climbing ladder 117 section by section and rotate it upward to a storage position that fits against the side wall of the transport platform body 11, so as to achieve compact storage and avoid affecting the operation of the vehicle or the passage of the clearance.

[0039] Optionally, the first telescopic mechanism 4 is a first cylinder. When the rail-mounted inspection vehicle needs to turn, the control device automatically controls the first cylinder to telescopically move according to a preset program; or, the operator can manually control the telescopic movement of the first cylinder through a controller to achieve steering adjustment between the connecting platform 3 and the operating platform 2. Preferably, the controller is a remote control, which facilitates flexible operation at the work site, improving ease of operation and operational safety.

[0040] Furthermore, such as Figures 1 to 3 As shown, the rail-mounted track installation inspection vehicle also includes: an overlap plate 200, which is disposed between the connecting platform 3 and the transport platform body 11 to form a continuous and smooth transition connection between the two, so as to facilitate the safe and smooth passage of operators between the transport platform body 11 and the connecting platform 3.

[0041] Specifically, such as Figures 1 to 3 As shown, the operating platform 2 includes: an operating platform body 21, which has an operating space 20; a connecting platform 3 connected to the operating platform body 21 on the side away from the transport platform 1 via a hinge; the rail-mounted inspection vehicle also includes: a second telescopic mechanism 5, the fixed end of which is fixedly connected to the side wall of the connecting platform 3, and the free end of the second telescopic rod 51 of each second telescopic mechanism 5 is hinged to the bearing plate 111 of the operating platform body 21; and the telescopic direction of the second telescopic rod 51 forms a second preset angle with the height direction of the connecting platform 3, the second preset angle being greater than 0° and less than 90°. The fixed end of the second telescopic mechanism 5 is higher than the free end of the second telescopic rod 51, so that when the second telescopic rod 51 of the second telescopic mechanism 5 extends, the height of the free end of the second telescopic rod 51 gradually decreases along the extension direction of the second telescopic rod 51.

[0042] With the above-described structure, the pitch angle of the operating platform 21 can be precisely controlled by the oblique drive of the second telescopic mechanism 5. This allows for dynamic adjustment based on changes in the elevation of the track installation point or the slope of the roadway, ensuring that the operating space 20 is always in the optimal working position and improving docking accuracy and operational comfort. By controlling the stroke of the second telescopic rod 51, the operating platform 2 can achieve height adjustment over a wide range, adapting to different installation height requirements. It is particularly suitable for track joints with large elevation differences, inclined shafts, or uneven roadway environments, significantly improving the equipment's versatility.

[0043] Furthermore, there are two second telescopic mechanisms 5, which are spaced apart along the width direction of the connecting platform 3.

[0044] Optionally, the second telescopic mechanism 5 is a second cylinder. The telescopic rod of the second cylinder drives the operating platform body 21 to swing downward or upward. When the operating platform body 21 needs to swing downward, the telescopic rod of the second cylinder extends; when the operating platform body 21 needs to swing upward, the telescopic rod of the second cylinder retracts.

[0045] When the rail-mounted inspection vehicle needs to climb or descend a slope, the control device automatically controls the extension and retraction of the second cylinder according to a preset program; alternatively, the operator can manually control the extension and retraction of the second cylinder via a controller to adjust the operating platform 2. Preferably, the controller is a remote control, which facilitates flexible operation at the work site, improving ease of operation and operational safety.

[0046] Furthermore, such as Figures 1 to 3 As shown, the operating platform body 21 includes: a second base plate 221, two fourth guardrails 222, and a fifth guardrail 223. The two fourth guardrails 222 are mounted on the second base plate 221, arranged opposite to each other and spaced apart along the width direction of the operating platform body 21. The fifth guardrail 223 is mounted on the second base plate 221, located between the two fourth guardrails 222, and on the side of the second base plate 221 away from the connecting platform 3. The fifth guardrail 223 is connected to each of the two fourth guardrails 222. The second base plate 221, the two fourth guardrails 222, and the fifth guardrail 223 form an operating space 20. The second base plate 221 is connected to the first base plate 32 of the connecting platform 3 via a hinge, thereby hinged the operating platform body 21 to the connecting platform 3.

[0047] Furthermore, such as Figures 2 to 3As shown, the rail-mounted inspection vehicle also includes: a first connector 6, a second connector 7, and a locking component. The first connector 6 extends along a preset arc trajectory and has multiple first connecting holes spaced apart along its extension direction. One end of the first connector 6 is connected to the connecting platform 3, and the other end faces the operating platform body 21. The second connector 7 is located on the side of the operating platform body 21 near the connecting platform 3, protruding from the operating platform body 21 and positioned opposite to the first connector 6. The second connector 7 has a second connecting hole that matches any one of the multiple first connecting holes. The locking component is used to connect with the second connecting hole and any one of the multiple first connecting holes. When the operating platform body 21 rotates relative to the connecting platform 3 to a target angle, one of the multiple first connecting holes is positioned opposite to the second connecting hole, and the locking component passes through the first connecting hole and the second connecting hole in sequence to lock the operating platform body 21 to the connecting platform 3.

[0048] Specifically, when the operating platform body 21 rotates relative to the connecting platform 3 around the hinge axis to the target pitch angle, the second connecting hole aligns with the first connecting hole at the corresponding position. At this time, the locking piece is inserted to fix the operating platform body 21 at the working angle, preventing attitude deviation caused by vibration or load changes during operation.

[0049] With the above-described structure, the operating platform body 21 can achieve precise positioning and rigid locking at multiple preset pitch angles through the arc-shaped first connecting member 6 and multiple spaced first connecting holes, along with alignable second connecting holes, meeting the installation requirements under different slopes, heights, or working postures. This locking mechanism uses a mechanical pin structure, eliminating the need for a complex control system to fix the angle. It is intuitive to operate, responds quickly, and maintains stable locking even under abnormal conditions such as power outages or hydraulic failures, ensuring high safety. Simultaneously, the multiple first connecting holes are evenly distributed along an arc-shaped trajectory, forming several standard angle positions. Operators can quickly select and lock the target angle according to actual needs, supporting frequent adjustments and reuse, improving work efficiency. Furthermore, after the locking member is connected, the operating platform body 21 and the connecting platform 3 form a rigid connection, effectively suppressing shaking caused by personnel movement, equipment vibration, or external impacts during operation, ensuring high-precision docking and safe operation.

[0050] Furthermore, there are two of each of the first connector 6, the second connector 7, and the locking member. Each of the first connector 6, the second connector 7, and the locking member is set in a one-to-one correspondence. The two first connectors 6 are spaced apart along the width direction of the connecting platform 3, and the two second connectors 7 are spaced apart along the width direction of the connecting platform 3 on the operating platform body 21.

[0051] Furthermore, the rail-mounted inspection vehicle also includes a second chain, which is connected to the connecting platform 3 and the operating platform body 21 respectively, and the second chain is located on the side wall of the connecting platform 3.

[0052] Optionally, there are two second chains, spaced apart along the width of the connecting platform 3.

[0053] Specifically, such as Figures 1 to 3 As shown, the operating platform 2 includes an operating platform body 21 and an anchor bolt drilling machine 22. The operating platform body 21 has an operating space 20. The anchor bolt drilling machine 22 is installed on the operating platform body 21, and at least a portion of the anchor bolt drilling machine 22 is located within the operating space 20. The anchor bolt drilling machine 22 is used to drill holes in the roof of the roadway. This facilitates the installation of anchor bolts and the hanging structure, thereby facilitating the installation of the track section 100 on the hanging structure. With this structural arrangement, the anchor bolt drilling machine 22 is integrated into the operating platform body 21, enabling the inspection vehicle to have dual functions of track installation and roadway support. Roof drilling can be completed before or simultaneously with track laying, avoiding equipment replacement and repeated vehicle entry, significantly improving the continuity and overall efficiency of roadway construction.

[0054] Furthermore, the bottom of the operating platform body 21 is provided with an installation hole that communicates with the operating space 20; the operating platform 2 also includes: a support frame 24, which is installed on the bottom of the operating platform body 21. The support frame 24 is provided with an installation cavity 241, which is arranged opposite to the installation hole and is connected to the operating space 20 through the installation hole. The bottom end of the anchor drilling machine 22 passes through the installation hole and is installed in the installation cavity 241.

[0055] Furthermore, the operating platform 2 also includes a storage box 25, which is installed on the operating platform body 21 and located on the side wall of the operating space 20. The storage box 25 has multiple storage slots for storing anchor rods and other components and tools such as hanging structures.

[0056] Specifically, such as Figures 1 to 3As shown, the operating platform 2 also includes a hoist 23, which is installed on the operating platform body 21 and located within the operating space 20. The hoist 23 is used to lift the track section 100 to be installed to a preset height. The hoist 23 and the anchor drilling machine 22 are spaced apart along the length of the operating platform body 21. With this structural arrangement, by installing the hoist 23 on the operating platform body 21, the track section 100 can be smoothly lifted from the second base plate 221 of the operating platform body to the preset height, facilitating the accurate transfer of the track section to the assembly station by operators, realizing a streamlined "lifting-connecting-fastening" workflow. This design effectively shortens the connection time between various processes, significantly improves the overall installation efficiency, and greatly reduces manual handling and lifting operations, lowering labor intensity and improving operational safety and comfort. Furthermore, the hoist 23 and the anchor drilling machine 22 are spaced apart along the length of the operating platform body 21, resulting in a compact and reasonable spatial layout and clear functional area division. Both can operate independently without interfering with each other, or they can work simultaneously according to construction needs, enabling the parallel advancement of track installation and roadway support procedures, and giving full play to the technical advantages of this inspection vehicle as "multi-functional and highly efficient".

[0057] Specifically, such as Figures 1 to 3 As shown, the transport platform 1 includes a transport platform body 11 and a traveling mechanism 12. The transport platform body 11 has a movable space 10. The traveling mechanism 12 is mounted on a track fixed above the tunnel and is movably mounted relative to the track along a preset track path. The transport platform body 11 is mounted on the connecting end of the traveling mechanism 12, so that the traveling mechanism 12 drives the transport platform body 11 to move. With this structural arrangement, the transport platform body 11 moves on the track through the traveling mechanism 12. Combined with its internal movable space 10, it realizes the on-board transport and on-site supply of the track section 100, truly achieving the integrated operation goal of "transportation-storage-installation" and reducing intermediate transfer links.

[0058] Furthermore, there are two walking mechanisms 12, and the two walking mechanisms 12 are respectively set with two second connecting brackets 114, and each walking mechanism 12 is connected to the corresponding second connecting bracket 114.

[0059] Furthermore, the track section 100 is constructed using I-beams as the track, and the traveling mechanism 12 includes at least one pair of traveling wheels 121. The pair of traveling wheels 121 are symmetrically arranged along the transverse direction of the track section 100, and are fitted into guide grooves within the track section 100. The pair of traveling wheels 121 are rotatably mounted on the track section 100. The traveling mechanism 12 also includes at least one pair of guide wheels 122. The pair of guide wheels 122 are symmetrically arranged on both side walls of the track section 100, and are respectively fitted into both side walls of the track section 100. Each guide wheel 122 rolls along a preset track path.

[0060] Specifically, such as Figure 3 As shown, the transport platform body 11 has a clearance opening on its support plate 111 for avoiding the track section 100. The transport platform 1 also includes a hoisting device 13, which is installed within the activity space 10. The hoisting part of the hoisting device 13 can lift the track section 100 located on the ground into the activity space 10 for storage through the clearance opening. With this structural arrangement, by setting the hoisting device 13 within the activity space 10, it is easier to vertically lift the track section from the ground and send it into the activity space 10, avoiding the cumbersome processes of traditional manual lifting and forklift transfer, significantly reducing labor intensity and operational risks. The hoisting device 13 is integrated into the transport platform body 11, eliminating the need for external lifting equipment, and enabling a highly efficient "lift as needed, load as needed" operation mode, shortening the track section replenishment time and ensuring the continuity of the installation process.

[0061] Furthermore, a support frame 16 is provided on the transport platform body 11. The support frame 16 extends along the width direction of the transport platform body 11 and is provided on the transport platform body 11. The hanging device 13 is slidably provided on the support frame 16 so as to facilitate the adjustment of the position of the hanging device 13.

[0062] Furthermore, a blocking plate 14 is provided at the avoidance opening for blocking or avoiding the avoidance opening. One side of the blocking plate 14 is rotatably connected to the support plate 111, so that the blocking plate 14 can rotate relative to the support plate 111 to open the avoidance opening for the hanging device 13 to operate when needed, or to close the avoidance opening when not in operation, so as to cover and block the opening area.

[0063] Optionally, the sealing plate 14 is flush with or slightly higher than the surface of the bearing plate 111 when it is closed, to ensure that the operator walks safely and stably on the transport platform body 11 and to prevent safety hazards such as stepping into the air or tripping.

[0064] Furthermore, the sealing plate 14 is provided with a handle 15 to facilitate the operator to open or close the sealing plate 14.

[0065] Optionally, the clearance opening is located in the middle of the bearing plate 111, which helps to evenly distribute the structural stress, improve the bearing stability of the transport platform body, and thus ensure the overall balance of the equipment during operation.

[0066] Specifically, such as Figures 1 to 4 As shown, the rail-mounted inspection vehicle also includes a drive unit 8, which is mounted on a track fixed above the roadway. The drive unit 8 is movably mounted relative to the track along a preset track path. The drive unit 8 is connected to the transport platform 1 to drive the transport platform 1. With this structural configuration, the drive unit 8 provides an independent power source for the entire vehicle, enabling the rail-mounted inspection vehicle to operate autonomously along the track without external traction. This significantly improves the mobility and operational flexibility of the equipment within the roadway, supporting various operating modes such as fixed-point stopping and continuous travel.

[0067] The first embodiment of the driving device 8 provided by this utility model is as follows: Figures 1 to 3 As shown, the drive device 8 includes: a pneumatic drive component 81, a pneumatic input component 82, and a braking component 83. The pneumatic drive component 81 is used to drive the transport platform 1 to move. The pneumatic drive component 81 and the braking component 83 are connected by a first traction rod 84. One end of the pneumatic drive component 81 is hinged to the first traction rod 84, and the other end of the braking component 83 is hinged to the first traction rod 84. The braking component 83 is located between the pneumatic drive component 81 and the transport platform 1. The braking component 83 is connected to the transport platform body 11 by a second traction rod 85. Both ends of the second traction rod 85 are hinged to the braking component 83 and the transport platform body 11, respectively. The pneumatic input component 82 is mounted on the first traction rod 84. The pneumatic input component 82 is connected to an external air source, a pneumatic drive component 81, and a braking component 83. The pneumatic input component 82 is used to deliver compressed air to the pneumatic drive component 81 and the braking component 83, so that the pneumatic drive component 81 can be driven by compressed air as a power source. At the same time, the braking component 83 can generate braking force by using air pressure or air control signals when it needs to stop, so as to achieve reliable braking.

[0068] Furthermore, the pneumatic drive component 81 includes: at least one pair of rotatably mounted bearing wheels 812 on the track, the pair of bearing wheels 812 being symmetrically arranged on both sides of the track web; two pneumatic cylinders, both of which are connected to the pneumatic input component 82, the two pneumatic cylinders using compressed air as a power source to achieve movement, and the drive ends of the two pneumatic cylinders being drivenly connected to the pair of bearing wheels 812 respectively, so that the two pneumatic cylinders can drive the corresponding bearing wheels 812 to rotate, thereby realizing the movement of the pneumatic drive component 81 along the preset track path.

[0069] The second embodiment of the driving device 8 provided by this utility model is as follows: Figure 4 As shown, the drive unit 8 includes a hydraulic drive component 86 and a power conversion component 87. The hydraulic drive component 86 is movably mounted on the track to drive the transport platform 1 to move. The power conversion component 87 is mounted on the outer wall of the transport platform body 11. The power conversion component 87 is connected to both an external air source and the hydraulic drive component 86. The power conversion component 87 is used to convert the input compressed air (air source) into hydraulic power and deliver high-pressure hydraulic oil to the hydraulic drive component 86 through hydraulic pipelines, thereby driving its operation.

[0070] Optionally, the power conversion component 87 is a pneumatic diaphragm pump.

[0071] Furthermore, the hydraulic drive component 86 is connected to the transport platform body 11 via the third traction rod 88, and the two ends of the third traction rod 88 are respectively hinged to the hydraulic drive component 86 and the transport platform body 11.

[0072] Furthermore, the hydraulic drive component 86 includes: a load-bearing wheel assembly 861 and a braking assembly 862. The load-bearing wheel assembly 861 includes at least one pair of load-bearing wheels 8611 rotatably mounted on the track, with the pair of load-bearing wheels 8611 symmetrically arranged on both sides of the track web. There are two braking assemblies 862, respectively mounted on both sides of the load-bearing wheels 8611. The braking assemblies 862 are used to generate braking force to achieve reliable braking.

[0073] Specifically, such as Figure 5 As shown, the rail-mounted inspection vehicle also includes a support device 9, which is movably mounted on the bottom of the operating platform 2. The support device 9 has an avoidance state and a support state. When the operating platform 2 is in a moving state, the support device 9 is in the avoidance state to avoid the ground of the tunnel. When the operating platform 2 moves to the target position, the support device 9 is in the support state, and the support device 9 contacts the ground of the tunnel to support the operating platform 2. With this structural arrangement, during rail installation and high-load or vibration operations such as anchor drilling, the support device 9 forms a rigid support with the ground, effectively suppressing the shaking, swaying, or sinking of the operating platform body 21, improving operational accuracy and safety. At the same time, the support device 9 has two states, "avoidance" and "support," and can automatically retract when the rail-mounted inspection vehicle is running and automatically deploy when working at a fixed point, achieving seamless function switching and balancing passability and operational performance. In addition, through a multi-point support structure, part or all of the load of the operating platform body 21 (including personnel, equipment, and track sections to be installed) is directly transferred to the roadway ground, reducing the stress on the track structure and preventing the risk of overturning due to uneven loading or center of gravity shift.

[0074] Furthermore, the support device 9 includes: two telescopic outriggers 91, a third connecting bracket 92, and a telescopic cylinder 93. The two telescopic outriggers 91 are spaced apart along the width direction of the operating platform body 21 and are swayably mounted at the bottom of the operating platform body 21 to switch between a support state and an avoidance state. The third connecting bracket 92 is U-shaped and is hinged to the two telescopic outriggers 91 to achieve synchronous linkage. The telescopic cylinder 93 is inclined at the bottom of the operating platform body 21, and the free end of the third telescopic rod of the telescopic cylinder 93 is connected to the third connecting bracket 92. The extension direction of the third telescopic rod of the telescopic cylinder 93 is inclined downward in the vertical plane, that is, it gradually decreases along the height direction, so as to drive the telescopic outriggers 91 to swing through the telescopic cylinder 93.

[0075] Optionally, when the telescopic cylinder 93 drives the third telescopic rod to extend, it pushes the third connecting bracket 92 to move downward, causing the two telescopic outriggers 91 to swing outward and downward in sync. At the same time, the two telescopic outriggers 91 extend until their bottom ends contact the roadway ground and enter the support state. When the third telescopic rod retracts, it drives the telescopic outriggers 91 to retract inward and upward, while the two telescopic outriggers 91 retract, causing them to lift off the ground and enter the avoidance state, thereby realizing the automatic deployment and retraction of the support device 9.

[0076] Among them, such as Figure 3 The direction indicated by the middle arrow A can be either the length direction of the operating platform body 21 or the length direction of the transport platform body 11.

[0077] Among them, such as Figure 3 The direction indicated by the middle arrow B can be the width direction of the connecting platform 3 or the width direction of the transport platform body 11, or the width direction of the operating platform body 21 or the lateral direction of the track segment 100.

[0078] Optionally, the installation process of the rail-mounted inspection vehicle for rail section 100 is as follows: 1. Initial preparation stage Three track sections 100 are manually installed as the initial track foundation. Then, the rail-mounted inspection vehicle is suspended and connected to the three installed track sections 100. An external air or hydraulic power source is connected to complete the equipment's power supply system. Before startup, all functions of the vehicle (including the drive unit, hoist, and support devices) are tested and verified to ensure normal operation of each mechanism. Simultaneously, the track sections 100 to be installed, along with matching connectors, anchor bolts, and other components, are stored in the movable space 10 of the transport platform body 11, completing the pre-operation preparations.

[0079] 2. Equipment positioning stage The drive unit 8 is activated, and its movement along the preset track path drives the transport platform 1 and the operating platform 2 to operate synchronously. When the transport platform 1 moves above the third track segment 100 and the operating platform 2 reaches the target installation position of the next track segment, i.e., the fourth track segment, the drive unit 8 is stopped to achieve precise positioning.

[0080] 3. Track docking and temporary fixing stage After the drive unit 8 stops, the support unit 9 remains in the retracted, avoidance position. The operator moves from the transport platform's activity space 10 into the operating platform's operating space 20. First, the lifting device 300 connects the third track segment 100 to the suspended structure 300 already installed on the tunnel roof, then its end is changed from a fixed state to an adjustable "moving end," reserving adjustment space for subsequent docking. Next, the hoist 23 is started, vertically lifting the fourth track segment 100 stored in the activity space 10 to the preset installation height. The operator assists in precisely docking one end of the fourth track segment 100 with the moving end of the third track segment 100, and after adjusting their positions, both are fixed to the same suspended structure 300, completing the initial connection of the fourth track segment 100.

[0081] 4. Support Operations and Cyclic Installation Phase After the installation of the first end of the fourth track segment 100 is completed, the operator returns to the activity space 10. The drive unit 8 restarts, and the inspection vehicle continues to move along the track. When the anchor drilling machine 22 on the operating platform body 21 reaches the far end of the fourth track segment 100, i.e., above the end to be fixed, the control equipment stops operating. Subsequently, the control support device 9 is activated, causing the telescopic outriggers 91 to extend downwards and contact the roadway ground, entering the support state and providing stable support for the operating platform.

[0082] The operator moves to the working area of ​​the anchor drilling machine 22, starts the equipment to drill holes in the tunnel roof, installs anchor bolts, and installs a new suspension structure 300 at that location. The fourth track segment 100 is then connected to the suspension structure 300 already installed in the tunnel via the lifting device 300, and the end of the fourth track segment 100 is pre-installed with the suspension structure 300. Step 3 is then repeated to install the fifth track segment 100. This cycle continues, achieving continuous track installation.

[0083] When encountering turning sections such as horizontal curves or vertical slopes, the first telescopic mechanism 4 drives the connecting platform 3 to rotate horizontally relative to the transport platform 1, achieving horizontal turning of the operating platform 2; the second telescopic mechanism 5 adjusts the pitch angle of the operating platform body 21, achieving vertical attitude adjustment. Through multi-degree-of-freedom adjustment, the trajectory of the rail-mounted inspection vehicle is ensured to remain consistent with the preset track path, guaranteeing track docking accuracy and operational safety.
