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 invention.

As shown in fig. 1, an auxiliary speed increasing device provided in an embodiment of the present invention includes: the auxiliary rail 100 is used for being installed at the side of the rail traveling equipment track 500, one auxiliary rail 100 is laid on each side of the rail traveling equipment track, and one or more connecting structures 200 are correspondingly arranged on each side of a bottom frame of each section of the carriage of the rail traveling equipment; both the attachment rail 100 and the connection structure 200 have a rolling assembly provided on one and an abutment plane provided on the other, the rolling assembly having a rolling member 410 capable of rolling thereon, and the rolling member 410 abutting against the abutment plane, which is parallel to the traveling direction of the guided traveling apparatus. Specifically, in the first embodiment, the connecting structure 200 may have a sliding plate 300 thereon, the sliding plate 300 may be disposed in a horizontal direction, the width of the sliding plate 300 may be 100 and 200mm, the length may be 1000 and 1500mm or correspond to the length of the car, the lower surface of the sliding plate 300 forms the abutment plane, and the rolling assembly is mounted on the upper surface of the auxiliary rail 100. In a second embodiment, the rolling assembly may be mounted on the connecting structure 200 with the rolling member 410 of the rolling assembly facing downwards, the upper surface of the accessory track 100 forming said abutment plane.

The reason for increasing the speed is described by taking the first embodiment as an example:

when the rail traveling apparatus is operated, traction power causes the wheels thereof to roll, and at this time, the lower surface of the sliding plate 300 of the coupling structure 200 is brought into contact with the rolling assemblies of the auxiliary rail 100, and the sliding plate 300 is pressed against the rolling assemblies. Under the action of pressure, the sliding plate 300 moves forwards, the rolling members 410 roll backwards, and interaction force is generated between the rolling members and the sliding plate 300, namely, the rolling members 410 can apply forward force to the sliding plate 300, the power formed by the pressure and the traction power generate a synergistic effect, the driving force is increased, the driving force and the traction power are generated simultaneously, and the driving force disappears, the pneumatic resistance cannot be increased, and no adverse factor exists. The system which is not driven by energy sources, starts by traction power and can generate larger power by being parallel to the traction power can be called a passive power system. The driving force is increased without consuming additional energy, and it is obvious that the speed of the rail bound travelling equipment is increased. Meanwhile, because the contact area between the rail traveling equipment and the auxiliary rail 100 is increased, the safety and the stability of the rail traveling equipment can be increased, and the influence of pressure waves on a vehicle body can be particularly reduced when two vehicles are in intersection and reconnection operation.

The weight of some rail traveling equipment is more than 460 tons, the pressure born by the wheels is distributed to partial pressure on the sliding plate 300, the pressure of the rail traveling equipment and the pressure of the sliding plate are in inverse proportion, the weight of the rail traveling equipment is reduced more and more when the output pressure of the equipment is higher, the pressure between the rail traveling equipment track 500 and the wheels of the rail traveling equipment is reduced, the weight of the wheels is reduced, the energy consumption is reduced, but the traveling speed is higher, and therefore the purpose of improving the traveling speed of the rail traveling equipment on the basis of lower energy consumption is achieved.

The measurement and calculation results of the rejuvenated train are as follows: when the vehicle runs at 350 km/h, the energy consumption per hundred kilometers per person is about 3.8 degrees, and if 20% of load is distributed to the connecting structure 200 and the rolling assembly, the energy consumption per hundred kilometers per person can be reduced to about 3 degrees.

The mounting groove 420 extends linearly and corresponds to the extending direction of the auxiliary rail 100, the number of the rolling members 410 in the mounting groove 420 is determined according to the length of the mounting groove 420, lubricating oil is injected into the mounting groove, a plurality of the rolling members 410 may be spaced apart in the extending direction of the mounting groove 420, the rolling members 410 are confined in the holder 430, and the holder 430 prevents the rolling members 410 from sliding in the mounting groove 420 so that the position thereof with respect to the mounting groove 420 is constant. The rolling member 410 is a ball, and the diameter of the rolling member 410 is greater than the depth of the mounting groove 420, so that a portion of the rolling member 410 is exposed outside the cover plate 440 through the relief hole of the cover plate 440, and specifically, the exposed portion may be one third of the rolling member 410. The rolling elements 410 may have a diameter of 50-100 mm. The balls can roll in multiple directions, thereby allowing the balls and the skid plate 300 to engage in forward hunting movements of the wheels.

And, can adjust the pressure that the butt plane exerts on rolling the subassembly through the lift actuating mechanism, can install pressure sensor on connection structure 200, pressure sensor and the joint control system control of rail advancing equipment are connected to realize the automatically regulated of pressure.

Likewise, the lift drive mechanism and linkage 200 may be extended away from the rail bound facility or retracted toward the rail bound facility by a telescoping drive mechanism to allow the abutment surface to travel over or be removed from the rolling assembly to avoid some obstruction.

In order to further reduce the damage of the connection structure 200, the connection structure 200 is provided with a shock-absorbing device connected with the rail bound travel equipment, wherein the shock-absorbing device comprises a spring, so that the hard contact between the sliding plate 300 and the rolling assembly is avoided, the sliding plate 300 is damaged, and the carriage is indirectly stable.

The auxiliary track 100 includes a plurality of arch supports, and an arch gap 110 is formed between two adjacent arch supports, and the arch gap 110 is used for avoiding a fastener of the track 500 of the rail-bound traveling equipment.

The position where the rolling assembly contacts the abutment plane is equal to or higher than the highest point of the railcar track 500. Taking the sliding plate 300 connected to the connecting structure 200 and the rolling assembly connected to the auxiliary track 100 as an example, the sliding plate 300 can move up and down under the action of the lifting driving mechanism, and also can be fixed relative to the tracked running device, and the highest point of the rolling assembly is equal to or higher than the highest point of the tracked running device track 500, which is beneficial for the tracked running device to be stable, and the sliding plate 300 can not be retracted and has no influence when passing through places where the auxiliary track 100 cannot be installed, such as a fork and the like.

The wheels and rails of the rail transportation system are both metal, the rolling friction relationship is realized by the rolling friction of the wheels and the rails no matter the rail is driven at high speed or braked, the weight of a train is more than 460 tons, the train is driven at the speed of 300 kilometers per hour, the contact area between the wheels and the rails is only more than 100 square millimeters, and the continuously changing complex load is borne in the small area, so the abrasion is difficult to avoid, the wheel tread is changed over time, the threat to the safety is formed, and the service life of the wheels and the rails is also influenced. Thus, the surface of the railed travel device track 500 in this embodiment has a wear resistant layer.
