In specific implementation, the back traction object 4 is used for generating tensioning traction force for the rope winding of the waist drum 25, so that the working principle of the Euler formula is realized.

Design calculations on back traction

In view of the fact that other mechanics and structural knowledge of the transmission line flexible track elevator except for the implementation of the working process by utilizing the Euler formula are simple, only the mechanics analysis between the bearing, the waist drum 25 and the back traction object 4 is performed.

The preconditions are set as follows: the bearing tension is S load, the back traction tension is S back, the friction coefficient between the surface of the waist drum wheel and the bearing rope 11 is mu, the number of turns of the waist drum wheel is n:

the stable operation conditions of the car 2 meeting the euler formula are as follows:

s load/S back ≦ e2 π n μ

If the weight of the car 2 and the person is 120kg, the number of turns of the rope wound on the waist drum 25 is 2, the friction coefficient is 0.2, and the weight of the back traction object to be tied is as follows:

s back ≧ 120/2.718282x3.14x2x0.2

S back ≧ 120/2.718282.5

S Back ≧ 10(kg)

Since the back traction object is a double-rope knot, the weight of each back traction object is only 5 kg.

Selection calculation for flexible track

Structure selection: since the curvature of the flexible track winding drum is 50mm, the flexible track winding drum is required to be better flexible; the requirement on the insulation grade is high in consideration of entering high-voltage and other electric fields; because the strength safety coefficient is 10 due to belonging to the manual tool carrying device.

The flexible track is selected as follows: the breaking tension of the insulating nylon rope is larger than 1200kg, the length of the rope is larger than twice of the climbing height, 18m of allowance is reserved, the lengthened rope can be used, but the contact must be arranged in the middle, the contact cannot prevent the car 2 from passing through after the insulated nylon rope is unfolded, the strength of the bearing rope 11 connected through the tying rope buckle is calculated according to 80%, and the strength of the bearing rope 11 connected through weaving is calculated according to 100%.

Drive layout and design calculations

The car 2 is driven by a 12v direct-current worm gear speed-reducing self-locking double-motor parallel driving mode, a synchronizer is arranged to ensure that the car 2 runs stably in the driving process, and a 12v lithium battery power supply is selected as a driving power supply.

Setting the maximum running weight of the car 2 to be 120kg, the ascending running speed to be 0.3 m/s and the mechanical efficiency to be 0.6, and selecting the running power of a motor W car:

w cage 120kg 0.3 m/s 10/0.6 600W

Considering that the double-motor parallel driving is selected, the power of a single motor is selected to be 400 w.

The speed of the ascending operation of the cage is 0.3 m/s, the diameter of the drum wheel is 50mm, and the rotating speed N of the drum wheel is calculated as follows:

n drum 0.3 1000 60/50/3.14 114.64 (rpm)

Because the drum wheel and the turbine rotate synchronously, the output rotating speed of the direct-current turbine worm and gear speed reduction self-locking motor can be selected to be 100-120 r/m.

And (3) drive selection: the 12v direct-current turbine worm speed-reducing self-locking motor has the power of 400w and the output rotating speed of 100-120 r/min.

Further, the driving power supply was a 12v lithium battery power supply, and the battery capacity was temporarily set to 60Ah (after the test was completed). The battery configuration is main, reserve configuration, and the battery operation supplies power, and reserve battery emergency service.

Furthermore, the driving control system is composed of a master button, a remote controller, a controller and a dry battery.

Furthermore, the main command button is manually operated by a passenger, is arranged on the car, has the functions of ascending, stopping, descending and power switching, and has various operations which are required to meet the requirements of the intermittent control of the electric traction.

Furthermore, the remote controller is used for remote operation of the car without passengers, so that people can get on and off the iron tower or enter a wire in sequence. The functions include ascending, stopping, descending and power switching, and various operations must meet the requirements of intermittent control of electric dragging.

Further, to prevent the system power supply from causing the controller to power off, the controller must have a self-powered power supply, a dry battery.

Furthermore, the controller is a multi-path main control contact (a non-contact switch), realizes the actions of ascending, descending, stopping and the like of the car driving motor, and directly switches and uses the standby battery when the battery of the running power supply cannot be used.

Further, the controller itself needs to be equipped with an operating power supply for its operation. The auxiliary contact has a self-locking function, and the descending button can be operated only by operating the stop button after the ascending button is operated. Also, after the down button is operated, only the stop button is operated, and the up button is operated. The manual operation and the remote control operation are sequentially performed, and the manual operation is prioritized over the remote control operation.
