The power transmission device mainly comprises a motor 3, a primary chain 4, a primary driven sprocket 5, a secondary driving sprocket 6, an idler 8, a driven chain 10, a secondary driven chain 11, an idler shaft 12, a driven gear 17, a turbine bearing seat 21, a turbine bearing seat 22, a worm 24, a turbine 25, a coupler 26, a primary driving sprocket 27 and a turbine shaft 28, the motor 3 is connected with the worm 24 through the coupler 26, the worm 24 is in meshing transmission with the worm wheel 25, the worm wheel 25 and the first-stage driving chain wheel 27 are fixedly connected to the turbine shaft 28, the worm wheel 24 and the turbine shaft 28 are respectively supported through the turbine bearing seat 22 and the turbine bearing seat 21, the first-stage chain 4, the first-stage driven chain wheel 5 and the first-stage driving chain wheel 27 form a set of chain transmission, the second-stage driving chain wheel 6, the driven chain 10 and the second-stage driven chain 11 form a set of chain transmission, the idler wheel 8 is meshed with the driven gear 17, and the idler wheel 8 and the second-stage driven chain wheel 11 are fixedly connected to the idler wheel shaft 12.
The supporting device mainly comprises a handrail 1, a seat board 2 and a supporting frame 14, wherein the handrail 1 and the seat board 2 are fixedly connected on the supporting frame 14.
When a user needs to go upstairs and downstairs by the aid of the device, a round or square climbing rod piece 23 is installed between the upper and lower floors, then the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 are hung on two side faces of the climbing rod piece 23, and due to the fact that the gravity center of the self-adaptive rod piece upstairs and downstairs device is located near the middle of the seat plate 2, the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 are tightly clamped on the running track under the action of self weight and lever force.
Then a user sits on a seat plate 2 of the device, holds a handrail 1, starts a motor 3, drives a lower clamping friction guide wheel shaft 19 to rotate through a worm 24 and a worm wheel 25 in sequence, drives a first-stage driving chain wheel 27, a first-stage chain 4 and a first-stage driven chain wheel 5, drives the lower clamping friction guide wheel shaft 19 to finally drive an upper clamping friction guide wheel shaft 16 to rotate through chain transmission of a second-stage driving chain wheel 6, a driven chain 10 and a second-stage driven chain 11 and transmission of an idler wheel shaft, turns through a direction change of an idler wheel 8, drives an upper clamping friction guide wheel 13 and a lower clamping friction guide wheel 9 to rotate oppositely and have the same rotating speed, drives the whole device to simultaneously move along an climbing rod piece 23 through a front-driving and rear-raking mode under the driving of the motor 3, controls the moving speed through controlling the rotating speed of the driving motor 3, and controls the forward and reverse rotation of the motor 3 in the upward and downward directions, thereby realizing climbing up and down the pole.
Because the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 have larger distance between the two wheels, no matter the shape of the climbing rod piece 23, no matter the shape is round, square and the like, as long as the space distance between the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 is larger than the diameter or the section width of the climbing rod piece 23, the device can be hung on the climbing rod piece 23 from one side of the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 and can be clamped on the climbing rod piece 23 in a self-adaptive manner by utilizing self weight.
Even if the climbing rod 23 is not vertically placed and forms a certain angle with the ground, the upper clamping friction guide wheel 13 and the lower clamping friction guide wheel 9 can still reliably hang on the climbing rod 23 and can be clamped on the climbing rod 23 in a self-adaptive manner by means of self weight.
Because the cross-sectional shapes of the lower clamping friction guide wheel 9 and the upper clamping friction guide wheel 13 are both U-shaped groove types, the inner walls of two sides of the U-shaped groove have good guiding functions in the process of ascending and descending of the whole device.
Through above-mentioned technical scheme, a self-adaptation member device upstairs and downstairs can carry the user and scramble from top to bottom along the member between the floor, can adapt to the member (round bar, square bar etc.) of multiple angle and multiple shape automatically, can follow member such as square bar, round bar of various angles from top to bottom, especially when erectting the pole setting of angle, can effectively shorten the climbing distance, reduces the climbing time, improves climbing efficiency. However, if the climbing rod 23 is not a straight rod but a curved rod, when a user goes upstairs or downstairs through the curved section of the climbing rod 23 by means of the adaptive rod, the inner walls of the two sides of the U-shaped groove of the lower clamping friction guide wheel 9 and the upper clamping friction guide wheel 13 are guided downwards, the lower clamping friction guide wheel 9 and the upper clamping friction guide wheel 13 both move forward along the curved section of the climbing rod 23, the axial position of the support shaft between the lower clamping friction guide wheel 9 and the upper clamping friction guide wheel 13 is fixed, at this time, the lower clamping friction guide wheel 9 and the upper clamping friction guide wheel 13 are locked, the whole device cannot move, that is, the device cannot realize flexible turning, and therefore, the invention provides the adaptive rod upstairs and downstairs turning device.
