The tunnel tire wheel rail interchange formula vehicle operation that this application embodiment provided can convert between tunnel pipe wall tire walking and tunnel rail-bound walking during to adapt to the different operation requirements of tunnel vehicle walking, wherein:
when the rail traveling operation is performed, the tire-wheel-rail interchange type traveling mechanisms connected to the front end and the rear end of the frame 100 are switched to a wheel-rail traveling mode, taking a tire-wheel-rail interchange type traveling mechanism as an example, the interchange mechanism 300 drives the wheel-rail traveling mechanism 200 to descend, so that two rail wheels 210 connected with the wheel-rail traveling mechanism 200 are abutted against the rail to perform the rail traveling operation, and meanwhile, the tire span changing mechanism 500 drives the two tire traveling mechanisms 400 to move towards the frame 100, so that the two tire traveling mechanisms 400 are retracted; specifically, the two upright cylinders 330 are controlled to respectively drive the cylinder rods to extend, so as to drive the wheel rail traveling frame 220 to stably descend, so that the rail wheels 210 connected with the shock-absorbing buffers at both ends of the wheel rail traveling frame 220 are driven to descend above the rail, at this time, the operator can align the two rail wheels 210 with the rail up and down by using the traverse positioning mechanism, namely, the rod of the traverse cylinder 360 is controlled to extend, the inner traverse sleeve 350 is driven to move along the width direction of the outer traverse sleeve 340 and the frame 100, thereby driving the column cylinder 330 and the wheel-rail traveling frame 220 connected to the inner traverse sleeve 350 to move in the width direction of the frame 100, so that the two rail wheels 210 are aligned with the rail, and finally the two post cylinders 330 further drive the wheel rail traveling frame 220 and the two rail wheels 210 to descend onto the rail, namely, two hydraulic motors 230 can be used to drive the corresponding rail wheels 210 to rotate so as to drive the tunnel tire wheel-rail interchange vehicle to move along the rail; simultaneously controlling oil cylinder rods of the two variable span oil cylinders 530 to contract, driving the two variable span inner sleeves 510 to move along the direction close to the frame 100 relative to the two variable span outer sleeves 520 so as to drive the two bogies 420 connected with the two variable span inner sleeves 510 to move towards the direction close to the frame 100, stopping pressing the outer peripheral wall of the tire 410 against the inner wall of the tunnel, and retracting the tire travelling mechanism 400; rotating the latch 450 to move it axially stops locking the position between the truck 420 and the swing axle 440 and the operator rotates the tire 410 about the spindle 430 to rotate the axis of the tire 410 to a horizontal orientation.
When a tire is used for traveling, the tire-wheel-rail interchange type traveling mechanisms connected with the front end and the rear end of the frame 100 are switched to a tire traveling mode, taking a tire-wheel-rail interchange type traveling mechanism as an example, the tire span changing mechanism 500 drives the two tire traveling mechanisms 400 to move away from the frame 100, so that the two tire traveling mechanisms 400 extend out, and in the span changing process, the tire 410 is rotated around the axis of the rotating shaft 430, so that the axis of the tire 410 rotates relative to a horizontal plane until the outer peripheral surface of the tire 410 is parallel to the inner wall of the preset position in the tunnel, and then the interchange mechanism 300 drives the wheel-rail traveling mechanism 200 to ascend, so that the two wheel-rail traveling mechanisms 200 are retracted, and the tire can travel on the inner wall of the tunnel; specifically, the cylinder rods of the two span-variable cylinders 530 are controlled to extend out to drive the two span-variable inner sleeves 510 to move in the direction away from the frame 100 relative to the two span-variable outer sleeves 520, so as to drive the two bogies 420 connected with the two span-variable inner sleeves 510 to move in the direction away from the frame 100, meanwhile, the bolt 450 is rotated to axially move to stop locking the position between the bogies 420 and the swing bridge 440, the operator rotates the tire 410 around the rotating shaft 430 to rotate the axis of the tire 410 up and down relative to the horizontal plane, controls the two upright cylinders 330 to contract the cylinder rods to reduce the height of the tire 410, enables the outer peripheral wall of the tire 410 to press against the inner wall of the tunnel, and finally controls the two upright cylinders 330 to respectively drive the cylinder rods to retract to drive the wheel track traveling frame 220 to stably rise, so as to drive the rail wheels 210 connected with the damping devices at the two ends of the wheel traveling frame 220 to rise and separate from the rail, so that the tire 410 can support the tunnel tire rail interchange vehicle to move along the inner wall of the tunnel, to facilitate movement and work in locations in the tunnel where no track is laid.
In addition, the tire steering mechanism in the tire traveling mechanism 400 can help the tire 410 to steer to adapt to the direction change of the tunnel, and specifically, the two slewing bearings 470 can be driven to rotate around the axes thereof in the horizontal plane by controlling the movement of the cylinder rods of the steering cylinders 480, so as to drive the angle measuring device 460, the slewing bearings 470, the bogie 420 and the tire 410 to rotate, so as to adjust the synchronous movement of the two tires 410 in each tire traveling mechanism 400 to steer to adapt to the direction change of the tunnel.
The tire balancing mechanism in the tire traveling mechanism 400 can ensure that the two sides of the tire 410 traveling along the inner wall of the tunnel are stressed in a balanced manner, when the tire 410 rotates and moves, the stress borne by the tire 410 is transmitted to the balancing beam 492 and the balancing pin 491 rotatably connecting the balancing beam 492 and the balancing hinge base 490, so that the tire 410 is balanced to be stressed excessively through the rotation action of the balancing pin 491, and the stress balance of each tire 410 during traveling is ensured.
