What is claimed is: 1. A guide rail beam for a rail vehicle, wherein the rail vehicle comprises a road wheel and a guide wheel located under the road wheel, and the guide rail beam comprises: a fixing plate disposed on a mounting surface; a flange plate, disposed above the fixing plate, wherein the road wheel is configured to travel on the flange plate; a web plate comprising a first surface and a second surface, wherein an upper end of the web plate is connected with the flange plate, a lower end of the web plate is connected with the fixing plate, the first surface and the second surface are exposed, and the web plate is in contact with and be associated with the guide wheel to guide a traveling track of the guide wheel; and a stiffening rib, wherein the stiffening rib is exposed, an upper end of the stiffening rib is connected with the flange plate, and a lower end of the stiffening rib is connected with the fixing plate. 2. The guide rail beam according to claim 1 , wherein a width direction of the stiffening rib is parallel to a width direction of the guide rail beam. 3. The guide rail beam according to claim 1 , wherein the stiffening rib is connected with the first surface or the second surface of the web plate. 4. The guide rail beam according to claim 3 , wherein a plurality of stiffening ribs are disposed; and the plurality of stiffening ribs are spaced apart from each other in a length direction of the guide rail beam. 5. The guide rail beam according to claim 1 , wherein a limiting flange is disposed on the flange plate, and is located above the guide wheel. 6. The guide rail beam according to claim 1 , wherein in a width direction of the guide rail beam, the web plate is disposed off a width center of the flange plate. 7. A track beam unit for a rail vehicle, comprising two guide rail beams, wherein the two guide rail beams are spaced apart from each other in a width direction of the rail vehicle, the rail vehicle comprises a road wheel and a guide wheel located under the road wheel, and each of the guide rail beams comprises: a fixing plate, disposed on a mounting surface; a flange plate disposed above the fixing plate, wherein the road wheel travels on the flange plate; a web plate comprising a first surface and a second surface, wherein an upper end of the web plate is connected with the flange plate, a lower end of the web plate is connected with the fixing plate, the first surface and the second surface are exposed, and the web plate is in contact with and be associated with the guide wheel to guide a traveling track of the guide wheel; a stiffening rib, wherein the stiffening rib is exposed, an upper end of the stiffening rib is connected with the flange plate, and a lower end of the stiffening rib is connected with the fixing plate; and a connecting member, wherein a first end of the connecting member is connected with a stiffening rib of a first guide rail beam of the two guide rail beams, and a second end of the connecting member is connected with a stiffening rib of a second guide rail beam of the two guide rail beams. 8. The track beam unit according to claim 7 , wherein the first end of the connecting member is further connected with a web plate of the first guide rail beam of the two guide rail beams, and the second end of the connecting member is further connected with a web plate of a second guide rail beam of the two guide rail beams. 9. The track beam unit according to claim 8 , comprising a plurality of connecting members and a plurality of stiffening ribs, wherein a number of the plurality of connecting members is the same as a number of the plurality of stiffening ribs of each of the guide rail beams. 10. The track beam unit according to claim 8 , wherein a reinforcing plate is disposed on the stiffening rib. 11. The track beam unit according to claim 10 , wherein the reinforcing plate comprises an upper plate body and a lower plate body, the connecting member is an I-shaped steel member, the upper plate body is flush with an upper flange of the connecting member, and the lower plate body is flush with a lower flange of the connecting member. 12. The track beam unit according to claim 8 , further comprising a supporting member, the supporting member is disposed on the connecting member, and an evacuation exit is defined by an upper space of the supporting member. 13. The track beam unit according to claim 12 , wherein a cable channel is disposed in the evacuation exit, and is disposed close to the web plate. 14. The track beam unit according to claim 7 , wherein an anti-slip layer is disposed on a surface of the flange plate associated with the road wheel. 15. The track beam unit according to claim 7 , wherein the first end of the connecting member is further connected with a web plate of the first guide rail beam of the two guide rail beams, and the second end of the connecting member is further connected with a web plate of the second guide rail beam of the two guide rail beams. 16.
