As shown in fig. 1 and 2, the present embodiment provides a vehicle chassis with multiple traveling modes, which includes a chassis body 100, two pairs of track traveling wheel sets 110 respectively disposed at two ends of the chassis body 100, and two track traveling mechanisms 120 respectively disposed at two sides of the chassis body 100, each track traveling wheel set 110 having a rotatable rail wheel 111 and configured to be rotatably connected to the chassis body 100 along a vertical plane, the chassis body 100 being hinged with a cylinder body of four tilting cylinders 130, the track traveling wheel set 110 including a tilting frame 113 hinged to the chassis body 100 through a rotating center shaft 112 and a fixed shaft 115, the tilting frame 113 being connected with the rotatable rail wheel 111 and a wheel-rail motor 114 for driving the rail wheel 111 to rotate, the tilting frame 113 being provided with a first fixed hole 116, the chassis body 100 being provided with a second fixed hole 117 corresponding to the first fixed hole 116, the oil cylinder rod of the turnover oil cylinder 130 is respectively hinged with the turnover frame 113 of each track running wheel set 110 so as to drive the turnover frame 113 to rotate along a vertical plane, when the turnover frame 113 rotates along the vertical plane, the outer peripheral wall of the track wheel 111 is driven to roll and abut against or separate from the track, and the chassis body 100 drives the track running mechanism 120 to lift and separate from the ground or fall to contact the ground; when the outer peripheral wall of the rail wheel 111 rolls against the rail and the chassis body 100 drives the crawler traveling mechanism 120 to rise and fall off the ground, the fixing shaft 115 axially moves through the first fixing hole 116 and the corresponding second fixing hole 117;

the chassis body 100 is further connected with a track span-changing mechanism for driving the two track running mechanisms 120 to move towards a direction close to or away from each other, the track span-changing mechanism comprises two track span-changing outer sleeves 140 extending along the width direction of the chassis body 100, each track running mechanism 120 is connected with a Z-shaped track span-changing inner sleeve 141 inserted in the track span-changing outer sleeve 140 in a sliding manner, and the chassis body 100 is further connected with a span-changing oil cylinder 142 for driving each track span-changing inner sleeve 141 to move along the corresponding track span-changing outer sleeve 140.

The vehicle chassis with multiple traveling modes provided by the embodiment can be switched between rail traveling and crawler traveling so as to travel on a rail or use a crawler on a track bed as required.

When the chassis needs to travel on the tracks, oil cylinder rods of four overturning oil cylinders 130 at two ends of the chassis body 100 are controlled to extend out, the overturning oil cylinders 130 drive overturning frames 113 of four track traveling wheel sets 110 to rotate along a vertical plane until the four overturning frames 113 drive the outer peripheral surfaces of rotatable track wheels 111 connected with the four overturning frames to respectively abut against two ends of the two tracks, at the moment, the four track wheels 111 abut against the tracks downwards to jack the chassis body 100 upwards to drive two crawler traveling mechanisms 120 at two sides of the chassis body 100 to lift off the ground, at the moment, wheel track motors 114 respectively connected with the overturning frames 113 of the four track traveling wheel sets 110 can be controlled to start to drive the four track wheels 111 to move along the two tracks, so that the chassis body 100 is driven to move along the tracks; when the vehicle needs to pass through a partially narrow section, the oil cylinder rods of the four variable-span oil cylinders 142 can be controlled to contract to drive the four track variable-span inner sleeves 141 to move along the two corresponding track variable-span outer sleeves 140, so that the two track traveling mechanisms 120 connected with the four track variable-span inner sleeves 141 move towards the direction close to the chassis body 100, the space occupied by the chassis body 100 in the width direction is reduced, and the passing capacity is improved. When the four turnover cylinders 130 respectively drive the corresponding turnover frames 113 to rotate until the outer peripheral walls of the rail wheels 111 are driven to roll and abut against the rails, the four second fixing holes 117 formed in the chassis body 100 are coaxially arranged corresponding to the first fixing holes 116 of the four turnover frames 113, at this time, an operator can push the four fixing shafts 115 to sequentially penetrate the four first fixing holes 116 and the corresponding second fixing holes 117, so that the four fixing shafts 115 are used for locking the relative positions of the four turnover frames 113 and the chassis body 100, the turnover frames 113 are ensured to drive the rail wheels 111 to stably abut against and roll along the rails, and when the rails need to be changed into crawler tracks, the four fixing shafts 115 are reversely pulled out from the four first fixing holes 116 and the corresponding second fixing holes 117 to release the locking.

When the chassis needs to walk on a track bed, oil cylinder rods of four overturning oil cylinders 130 at two ends of the chassis body 100 are controlled to contract, the overturning oil cylinders 130 drive overturning frames 113 of four rail walking wheel sets 110 to reversely rotate along a vertical plane until the four overturning frames 113 drive the outer peripheral surfaces of the rotatable rail wheels 111 connected with the overturning frames to separate from two rails, at the moment, the four rail wheels 111 stop downwards abutting against the rails to jack the chassis body 100 upwards, so that the bottom ends of two crawler walking mechanisms 120 at two sides of the chassis body 100 descend to abut against the ground, and at the moment, the two crawler walking mechanisms 120 at two sides of the chassis body 100 can be used for driving the chassis body 100 to perform crawler movement; when the distance between the two crawler belt traveling mechanisms 120 needs to be adjusted, before the bottom ends of the two crawler belt traveling mechanisms 120 descend to abut against the ground, oil cylinder rods of the four variable-span oil cylinders 142 are controlled to extend out to drive the four crawler belt variable-span inner sleeves 141 to move along the corresponding two crawler belt variable-span outer sleeves 140, the two crawler belt traveling mechanisms 120 connected with the four crawler belt variable-span inner sleeves 141 move in the direction away from the chassis body 100, the distance between the two crawler belt traveling mechanisms 120 is adjusted to the required width, and therefore the track bed traveling requirements under different conditions are met.

As shown in fig. 3, in another alternative embodiment, four locking cylinders 118 are further connected to the chassis body 100, and cylinder rods of the four locking cylinders 118 are respectively and coaxially connected to the four fixing shafts 115 to drive the fixing shafts 115 to move axially, so that an operator can drive the four fixing shafts 115 to move axially through the first fixing holes 116 and the corresponding second fixing holes 117 by controlling the cylinder rods of the four locking cylinders 118 to extend and retract, so as to lock positions of the chassis body 100 and the roll-over carriage 113 by using the fixing shafts 115, so that the roll-over carriage 113 is driven by the roll-over cylinder 130 to rotate until the outer circumferential wall of the rail wheel 111 is driven to roll against the rail, and the roll-over carriage 113 is ensured to drive the rail wheel 111 to stably press against and roll along the rail by using the fixing shafts 115.

The embodiments described above are some, but not all embodiments of the present application. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
