DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-7 As shown, this embodiment is a walking training ceiling rail system suitable for installation in a stair environment, comprising a head 1 and a track 2, wherein the head 1 moves along the track 2, and other related training equipment 3 is connected to the head 1 and driven by the head 1 to move. Figure 1In order to allow the overhead rail system to climb stairs and ramps, the track 2 in this embodiment includes a flat section and a sloped section, wherein a rack 4 is provided at the top of the track 2 in the sloped section, and no rack 4 is provided at the top of the track 2 in the flat section.

[0020] The head 1 in this embodiment includes a carrier 10, a roller mechanism and a driving mechanism, the roller mechanism and the driving mechanism are arranged on the carrier 10, the roller mechanism rolls in the track 2, the driving mechanism includes a power assembly and a lever assembly, the lever assembly includes a lever 11, a spring plunger 12, a driving gear 13 and a driving roller 14, the driving gear 13 and the driving roller 14 are arranged on the lever 11, and the driving gear 13 is located at the rear end of the lever 11, the power assembly is used to drive the driving gear 13 and the driving roller 14, that is, the power assembly is used to drive the driving gear 13 and the driving roller 14. The lever 11 is rotatably connected to the carrier 10, and the spring plunger 12 is arranged above the head end of the lever 11. In this embodiment, a plunger seat 15 is arranged on the carrier 10 above the head end of the lever 11, and the spring plunger 12 is installed on the plunger seat 15; the spring plunger 12 is used to apply downward pressure to the head end of the lever 11. Under the pressure of the spring plunger 12, when the head 1 walks on the slope section of the track 2, the driving gear 13 is meshed with the rack 4, and the driving roller 14 does not contact the lower surface of the track 2. At this time, the head 1 is driven by the driving gear 13 to walk, see the attached Figure 6 When the machine head 1 moves on the flat section of the track 2, the rack 4 disappears, so the tail end of the lever 11 swings upward a certain distance. At this time, the driving roller 14 presses the lower surface of the track 2, and the machine head 1 is driven by the driving roller 14 to move. Figure 7 .

[0021] like Figure 2 and 3 As shown, in this embodiment, the roller mechanism includes two hanging wheels 16 and two vertical rollers 17, wherein the hanging wheels 16 are located inside the track 2 to bear the weight of the machine head 1, and the vertical rollers 17 are located outside the track 2 to press the lower surface of the track 2 to prevent the machine head 1 from moving up and down; the roller mechanism also includes four horizontal rollers 18, the horizontal rollers 18 are used to press the left and right inner walls of the track 2 to prevent the machine head 1 from swinging left and right, and are used for guiding when passing through a curved track; a conductive bar 5 is installed on each of the left and right inner walls of the track 2, and the roller mechanism also includes two conductive wheels 19, which press the conductive bar 5 under the action of a spring to supply power to the machine head 1; the solution of powering the entire track inside the track 2 has the advantages of beautiful appearance and high safety performance.

[0022] In this embodiment, the power assembly includes a servo motor 6 and a driving gear 20. The servo motor 6 is used to drive the driving gear 20, and the driving gear 20 is used to drive the driving gear 13 and the driving roller 14. Figure 4As shown, specifically, the lever assembly also includes a first transition gear 21, a second transition gear 22, and a third transition gear 23 arranged on the lever 11. The first transition gear 21 is meshed with the driving gear 20. The first transition wheel shaft 211 of the first transition gear 21 passes through the opening 114 on the lever 11 close to the driving roller 14 and is connected to the carrier 10, so that the lever 11 can rotate around the first transition wheel shaft 211. The first transition wheel shaft 211 is both the rotation axis of the first transition gear 21 and the fulcrum axis of the lever 11. Therefore, when the lever 11 swings up and down, the center distance between the first transition gear 21 and the driving gear 20 can be ensured to remain unchanged, so that the gear meshing remains stable.

[0023] The second transition gear 22 is meshed with the first transition gear 21 and the third transition gear 23 at the same time. The second transition gear 22 is directly connected to two driving rollers 14. The two driving rollers 14 are respectively located on both sides of the lever 11. The second transition gear 22 is used to drive the two driving rollers 14; the third transition gear 23 is meshed with the driving gear 13. Since the third transition gear 23 is meshed between the second transition gear 22 and the driving gear 13, the rotation directions of the driving gear 13 and the driving roller 14 are the same, and they can drive the machine head 1 to move respectively.

[0024] like Figure 5 As shown, in this embodiment, the lever 11 includes two symmetrically arranged plates 111, a connecting block 112 is connected between the edges of the two plates 111, a first transition gear 21, a second transition gear 22, a third transition gear 23 and a driving gear 13 are arranged between the two plates 111, and a driving roller 14 directly connected to the second transition gear 22 is arranged on the outside of the plate 111; the driving gear 20 is located between the two plates 111, and a notch 113 is formed on the plate 111 for avoiding the axle where the driving gear 20 is located.

[0025] like Figure 1 As shown, in this embodiment, the track 2 is installed above the training route, the training route is located in the stairwell, and the track 2 spirals up in the stairwell to facilitate patients to perform stair climbing training; the track 2 is composed of an upper curved rail, a lower curved rail, a horizontal curved rail and a straight rail; the material of the track 2 can be aluminum alloy profiles.

[0026] like Figure 6 As shown, when the machine head 1 moves on the slope section of the track 2, the driving gear 13 is meshed with the rack 4, and the driving roller 14 is not in contact with the lower surface of the track 2. At this time, the machine head 1 is driven by the driving gear 13; with the cooperation of the spring plunger 12 and the lever 11, the driving gear 13 and the rack 4 always remain in meshing state. Since the meshing mode of the gear and the rack is more secure, there is no risk of slipping of the machine head 1 during the climbing process, and the safety factor is relatively high.

[0027] like Figure 7As shown, when the machine head 1 moves on the flat section of the track 2, since the rack 4 disappears, under the pressure of the spring plunger 12, the lever 11 rotates around the first transition wheel shaft 211, and the tail end of the lever 11 swings upward for a certain distance, and the driving roller 14 presses the lower surface of the track 2. At this time, the machine head 1 is driven to move by the driving roller 14; under the cooperation of the spring plunger 12 and the lever 11, the driving roller 14 is tightly pressed against the lower surface of the track 2 to ensure that the driving roller 14 does not slip during rotation.

[0028] When the machine head 1 changes from the flat section of track 2 to the sloping section of track 2, the driving gear 13 re-engages with the rack 4, and the tail end of the lever 11 swings downward for a certain distance. At this time, the driving roller 14 swings downward for a certain distance to leave the lower surface of track 2, and changes to the driving gear 13 to drive the machine head 1 to move.

[0029] The present invention realizes that when climbing stairs or ramps, the overhead rail system can utilize the driving gears to cooperate with the slope section track to perform safe and smooth climbing, and on flat sections, the overhead rail system can utilize the driving rollers to perform conventional horizontal movement. The adaptability is greatly improved compared with the existing solutions, and it is suitable for various training scenarios, and can realize cross-floor training, meeting the patients' stair climbing training needs and increasing the diversity of rehabilitation training; at the same time, it can also improve the utilization rate of hospital venues and realize necessary rehabilitation training using the existing hospital venues.
