Description

Technical Field

[0001] This utility model relates to the field of tunnel transportation equipment technology, specifically to an articulated device for a tunnel rubber-tired transport vehicle. Background Technology

[0002] Tunnel rubber-tired vehicles are vehicles specifically designed for transportation operations within tunnels. They are widely used in mining, subway construction, tunnel construction, and other fields, and can adapt to complex working environments. Although tunnel rubber-tired vehicles perform well in many application scenarios, their adaptability in steering, climbing, and complex working conditions is still somewhat limited due to the overall length and load-bearing capacity of the vehicle.

[0003] Traditional tunnel rubber-tired transport vehicles, due to their long bodies, typically suffer from significant problems in steering and climbing adaptability, especially in narrow tunnel environments, limiting their maneuverability in confined spaces. When traveling on curved or longitudinally deviated road surfaces, they also face challenges of torsion and bending. Furthermore, their steering performance may decrease under load, particularly when transporting heavy loads, affecting steering flexibility and stability. Most existing tunnel rubber-tired transport vehicles are only suitable for long, straight tunnels, unable to operate on tunnel construction and transportation routes with small-radius turns, sharp bends, or steep gradients, exhibiting problems such as large turning radii and low adaptability to tunnel conditions. Summary of the Invention

[0004] This invention addresses the problems of large turning radius and low adaptability to tunnel working conditions in existing tunnel rubber-tired transport vehicles by providing an articulation device for such vehicles. This device enables the tunnel rubber-tired transport vehicle to achieve multi-degree-of-freedom torsion, small-radius turning of the entire vehicle, and allows it to adapt to complex working conditions with differences in incline, lateral gradient, and lateral slope, thereby reducing the torque and bending load on the vehicle body when traveling on complex road surfaces.

[0005] To achieve the above objectives, the technical solution of this utility model is: a hinged device for a tunnel rubber-tired transport vehicle, comprising a front frame and a rear frame, and further comprising a hinged mechanism disposed between the front frame and the rear frame. The hinged mechanism includes a connecting plate, a connecting component, and a rotating component, with the connecting component disposed at both ends of the connecting plate. The hinged mechanism is installed between the front frame and the rear frame, serving to connect the front frame and the rear frame, and providing both connection and auxiliary steering functions.

[0006] The connecting assembly includes a first platform, a second platform, and a fixed frame. The first platform is hinged to the second platform and horizontally hinged to the connecting plate. The fixed frame is connected to the second platform via a rotating assembly. The hinged connection between the first and second platforms allows the hinge mechanism to swing up and down, enabling the tunnel rubber-tired transport vehicle to adapt to downhill and forward driving conditions. When the tunnel rubber-tired transport vehicle travels on an inclined road surface, the rotating assembly allows the front and rear frames to twist, enabling the tunnel rubber-tired transport vehicle to adapt to lateral slope differences in the direction of travel.

[0007] Adjustment components are provided on both sides of the connecting plate. The telescopic ends of the two adjustment components are respectively hinged to one side of the two platforms, and the tail end of the adjustment component is hinged to the connecting plate. By controlling the adjustment components, the turning radius of the tunnel rubber-tired transport vehicle can be reduced, achieving small-radius turning adaptability and consistency of turning direction.

[0008] Furthermore, each end of the connecting plate is provided with a pin, and the connecting plate is hinged to the frame via the pin. The pin facilitates the hinge between the connecting plate and the frame, and allows for relative rotation under the action of the adjusting assembly, enabling the tunnel rubber-tired transport vehicle to achieve small-radius turns.

[0009] Furthermore, grooves are provided at both ends of the connecting plate, and the first pin is fixedly disposed in the groove, which provides an installation position for the first pin.

[0010] Furthermore, a second pin is provided on the side of the second platform close to the first platform, and the first platform is hinged to the second platform via the second pin. The second pin facilitates relative rotation between the second and first platforms, allowing the tunnel rubber-tired transport vehicle to traverse concave and convex road surfaces, thus enabling the tunnel rubber-tired transport vehicle to adapt to complex working conditions such as uphill and downhill slopes.

[0011] Furthermore, the mounting brackets of the two connecting components are respectively fixedly connected to the front frame and the rear frame. The connecting components, through the action of the mounting brackets, connect to the front frame and the rear frame, achieving the purpose of installing the articulation mechanism between the front frame and the rear frame.

[0012] Furthermore, the adjustment components form a triangular structure with the connecting plate and the frame, and the telescopic ends of the two adjustment components face opposite directions, so that the horizontal steering of the hinge mechanism can be achieved through the action of the two adjustment components.

[0013] Furthermore, both the first platform and the connecting plate are provided with a third pin, and the tail end and telescopic end of the adjustment component are respectively hinged to the connecting plate and the first platform via the third pin.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model has a reasonable structure and good performance. The device enables the tunnel rubber-tired transport vehicle to achieve multi-degree-of-freedom torsion, small-radius turning of the whole vehicle, and to pass through various complex road surfaces. It also enables the tunnel rubber-tired transport vehicle to adapt to complex working conditions with differences in incline, lateral gradient, etc., reduces the torque and bending load on the vehicle body when the tunnel rubber-tired transport vehicle is driving on complex road surfaces, improves the adaptability of the tunnel rubber-tired transport vehicle to complex working environments, and expands the application range of the tunnel rubber-tired transport vehicle.

[0015] 2. The adjustment component of this utility model is hinged to the connecting plate and the frame. By controlling the extension and retraction length of the adjustment component to assist steering, the horizontal steering of the hinge mechanism is realized, so that the tunnel rubber-tired transport vehicle can make small-radius turns, realizing the adaptability of the tunnel rubber-tired transport vehicle to make small-radius turns and the consistency of controlling the turning direction.

[0016] 3. The connecting component fixing frame of this utility model is connected to the platform in two phases through the slewing component. When the tunnel rubber-tired transport vehicle travels on an inclined road surface, the front frame and the rear frame will generate a torsional arc. The front frame and the rear frame can be torn by the slewing component at the end of the fixing frame, so as to realize the adaptability of the tunnel rubber-tired transport to the working conditions of the lateral slope difference in the direction of travel.

[0017] 4. The first and second platforms of the connecting assembly of this utility model are hinged together, and the front and rear frames can rotate around the hinge point of the first and second platforms, so as to facilitate the tunnel rubber-tired transport vehicle to pass through concave and convex road conditions, so that the tunnel rubber-tired transport vehicle can adapt to the complex working conditions of uphill and downhill slopes.

The hinge mechanism includes a connecting plate 3, connecting components, and a rotating component 7. The connecting components are disposed at both ends of the connecting plate 3. In this embodiment, the hinge mechanism is arranged at the middle position of the chassis of the front frame 1 and the rear frame 2, connecting the front frame 1 and the rear frame 2, and has the functions of connection and auxiliary steering. The connecting plate 3 connects the front frame 1 and the rear frame 2 through two connecting components, thereby achieving the effect of connecting the front frame 1 and the rear frame 2 together.

[0021] The connecting assembly includes a first platform 4, a second platform 5, and a fixed frame 6. The first platform 4 is hinged to the second platform 5 and horizontally hinged to the connecting plate 3. The fixed frame 6 is connected to the second platform 5 via a rotating assembly 7. In this embodiment, the hinge between the first platform 4 and the second platform 5 allows the hinge mechanism to swing up and down, thereby causing the front frame 1 and the rear frame 2 to move up and down. This facilitates the tunnel rubber-tired transport vehicle's ability to traverse concave and convex road surfaces, enabling the vehicle to adapt to both upward and downward slope conditions.

[0022] In this embodiment, the slewing assembly 7 can be a slewing bearing. The fixed frame 6 is connected to the second platform 5 through the slewing bearing, so that the front frame 1 and the rear frame 2 can rotate through the slewing bearing. When the tunnel rubber-tired transport vehicle passes through the inclined plane road surface, the front frame 1 and the rear frame 2 will have planes at different angles. The tunnel rubber-tired transport vehicle will deflect at a certain angle. The front frame 1 or the rear frame 2 will rotate through the slewing assembly 7 at the end of the fixed frame 6, so that the tunnel rubber-tired transport vehicle can pass through the working area with changes in lateral curvature, realizing the adaptability of the tunnel rubber-tired transport vehicle to the working environment with differences in lateral slope in the direction of travel.

[0023] Adjustment components 8 are provided on both sides of the connecting plate 3. The telescopic ends of the two adjustment components 8 are respectively hinged to the two platforms 4, and the tail end of the adjustment component 8 is hinged to the connecting plate 3. In this embodiment, the adjustment components 8 can be hydraulic cylinders. When the tunnel rubber-tired transport vehicle turns, the front frame 1 and the rear frame 2 can rotate around the end of the connecting plate 3. The telescopic length of the adjustment components 8 is controlled to assist in steering, thereby realizing the horizontal steering of the tunnel rubber-tired transport vehicle and achieving adaptability to small-radius turns and consistency in controlling the turning direction.

[0024] Both ends of the connecting plate 3 are provided with pins 301, and the connecting plate 3 is hinged to the platform 4 through the pins 301. In this embodiment, the pins 301 facilitate the rotation of the connecting plate 3 relative to the platform 4, thereby facilitating the turning of the tunnel rubber-tired transport vehicle in the horizontal direction.

[0025] Both ends of the connecting plate 3 are provided with grooves, and the pin 301 is fixedly disposed in the grooves. In this embodiment, the grooves provide an installation position for the pin 301 so that the connecting plate 3 can be hinged to the frame 4 via the pin 301.

[0026] A second pin 501 is provided on the side of the second platform 5 near the first platform 4, and the first platform 4 is hinged to the second platform 5 via the second pin 501. In this embodiment, a pin seat for mounting the second pin 501 is installed at the end of the second platform 5 near the first platform 4. The second pin 501 allows the second platform 5 to rotate relative to the first platform 4, facilitating the passage of the tunnel rubber-tired transport vehicle through concave and convex road surfaces.

[0027] The fixing brackets 6 of the two connecting components are fixedly connected to the front frame 1 and the rear frame 2, respectively. In this embodiment, the front frame 1 and the rear frame 2 are connected together by the fixing brackets 6 of the connecting components, thereby achieving the purpose of installing the hinge mechanism between the front frame 1 and the rear frame 2.

[0028] The adjusting component 8 forms a triangular structure with the connecting plate 3 and the platform 4, and the telescopic ends of the two adjusting components 8 face opposite directions. In this embodiment, the telescopic ends of the two adjusting components 8 face opposite directions to ensure that the adjusting components 8 can assist the tunnel rubber-tired transport vehicle in steering by controlling their telescopic length.

[0029] Both the platform 4 and the connecting plate 3 are equipped with pins. The tail end and telescopic end of the adjusting component 8 are respectively hinged to the connecting plate 3 and the platform 4 via the pins. In this embodiment, the pins facilitate the hinged connection between the adjusting component 8 and the connecting plate 3 and the platform 4, thereby enabling the adjusting component 8 to assist in steering the tunnel rubber-tired transport vehicle by controlling the extension and retraction length of its telescopic end.

[0030] When using this utility model, such as Figure 3 As shown, when the tunnel rubber-tired transport vehicle travels on a level road surface, the articulated mechanism does not undergo any state change; as Figure 4 As shown, when the tunnel rubber-tired transport vehicle turns, the front frame 1 and the rear frame 2 rotate around the two ends of the connecting plate 3 respectively. During the turning process, the adjusting component 8 controls the extension and retraction length of its telescopic end to assist the tunnel rubber-tired transport vehicle in turning, thereby realizing the adaptability of the tunnel rubber-tired transport vehicle to small-radius turns and the consistency of controlling the turning direction.

[0031] like Figure 5 , 6 As shown, when the tunnel rubber-tired transport vehicle passes through concave or convex road surfaces, i.e. when going uphill or downhill, the front frame 1 and the rear frame 2 rotate around the hinge pin 501 of the first frame 4 and the second frame 5, so that the entire tunnel rubber-tired transport vehicle can pass through the working conditions of concave and convex road surfaces, thereby achieving the effect of the tunnel rubber-tired transport vehicle being able to adapt to complex working conditions of going uphill and downhill.

[0032] like Figure 7 As shown, when the tunnel rubber-tired transport vehicle passes through the inclined plane road surface, the front frame 1 and the rear frame 2 will have planes at different angles. The tunnel rubber-tired transport vehicle will deflect at a certain angle. The front frame 1 or the rear frame 2 will rotate through the slewing component 7 at the end of the fixed frame 6, so that the tunnel rubber-tired transport vehicle can pass through the working area with changes in lateral curvature, realizing the adaptability of the tunnel rubber-tired transport vehicle to the working environment with differences in lateral slope in the direction of travel.
