[0019] The utility model will be further explained in detail in combination with the drawings.

[0020] Please refer to Figure 1 The utility model discloses a track type gravity energy storage external drive station which comprises drive station assemblies 1 symmetrically arranged on both sides of a track, wherein each drive station assembly 1 comprises a support platform 2, a support frame 3 slidably arranged on the support platform 2, a motor 4 arranged on the upper side of the support frame 3, a reduction box 5 arranged on the output end below the motor 4, and a drive wheel 6 connected with the output shaft of the reduction box 5, and the support frame 3 is connected with a tensioning device.

[0021] In the embodiment, the track 7 is provided for the track train 8 to travel, and the track train 8 is connected by a plurality of flat cars 10 through universal joints. Each flat car 10 comprises a vehicle frame, a loading plate 11 arranged on the vehicle frame, a wheel set 17 arranged on both sides below the vehicle frame, and a drive plate 12 arranged on both sides of the loading plate 11. An appropriately matched gap is arranged at one end between adjacent drive plates 12, so as to avoid collision and interference between the drive plates 12 of the front and rear flat cars 10 when the track train 8 climbs a slope, turns and passes a curve.

[0022] When the track train 8 travels to the drive station assembly 1, the motor 4 outputs a torque and transmits the torque to the drive wheel 6 through the reduction box 5. The drive wheel 6 extrudes and rubs against the drive plate 12. The drive wheel is tightly pressed against the drive plate 12 under the action of the tensioning device. Thus, the driving force is transmitted to the flat car 10 and the entire track train 8, so as to drive the track train 8 to travel stably on the track 7. The track train 8 travels at an arbitrary position on the track 7, and is connected with at least one drive station. Since the more the number of flat cars of the track train 8 is, the greater the driving force required is, the output force of the drive station has certain requirements. The external drive station is not limited in space, and a high-power motor 4 and a large-size drive wheel 6 can be arranged to improve the output force of the drive station. Thus, the number of the drive stations arranged can be reduced, and the cost can be reduced. In addition, the external drive station is arranged on both sides of the track 7, so that the running state of the drive station is clear at a glance, and the drive station is more convenient to overhaul and adjust.

[0023] In actual application, when the flat carriages 10 arranged in the rail train 8 are too long, in order to guarantee the stable transportation of the rail train 8, the number of driving stations needs to be increased according to the driving force required by the rail train 8, or the power of the electric motor 4 and the size of the driving wheel 6 need to be adjusted to match the driving force required by the rail train 8, which needs to be designed and adjusted according to the actual situation.

[0024] In the embodiment, the tensioning device comprises two parallel sliding rails 9 arranged on the support platform 2, sliding blocks 13 respectively slidingly fitted on the two sliding rails 9 and fixedly connected with the bottom of the support frame 3, and a linear telescopic driving member 14 arranged on the support platform 2 and having an output end fixedly connected with the support frame 3.

[0025] The tensioning device can drive the support frame 3 to slide and adjust the tension of the electric motor 4, the reduction gearbox 5 and the driving wheel 6 on the sliding rails 9.

[0026] In the embodiment, the linear telescopic driving member 14 comprises a telescopic end and a fixed end, and the fixed end is arranged on the support platform 2 through a support block 15, and the telescopic end is connected with the support frame 3.

[0027] The output shaft of the reduction gearbox 5 is connected with the rotating shaft of the driving wheel 6 through a coupling 16, and the coupling 16 is used for stably transmitting the output power of the reduction gearbox 5 to the driving wheel 6.

[0028] The driving wheels 6 of the symmetrically arranged driving station assemblies 1 are perpendicular to the rail 7 along the axis, so that the driving force on both sides is consistent, thereby avoiding the problem of rollover of the rail train 8 due to unbalanced force on both sides.
