Drives for ropeways

Abstract

The invention discloses a driving machine for a ropeway. The driving machine comprises a frame, a hollow shaft, a solid shaft, a driving wheel, a motor and a driving connecting piece, wherein the hollow shaft is arranged on the frame; the solid shaft is sleeved in the hollow shaft; the driving wheel is rotationally arranged on the hollow shaft; the motor is connected with the upper end of the solid shaft and used for driving the solid shaft to rotate; and the driving connecting piece is connected with the lower end of the solid shaft and the driving wheel respectively. According to the driving machine for the ropeway of the invention, when the driving machine is in a normal state, a bending moment is mainly transmitted by the hollow shaft, the total weight of the driving wheel is borne by the hollow shaft, and the solid shaft is used for transmitting torsion without bearing any weight except that of the solid shaft. After the hollow shaft is broken due to fatigue or an accident, the solid shaft can effectively bear the total weight of the driving wheel to prevent the driving wheel from falling onto the ground and causing an accident so as to play a role in protecting the broken shaft.

Description

[0001] This application is a divisional application with the filing date of December 23, 2009, the application number: 200910243855.6, and the name "Driver for Cableway". technical field [0002] The invention relates to a driving machine, in particular to a driving machine used for a cableway and having a broken shaft protection function. Background technique [0003] The transmission shaft of the driving machine of the traditional cableway is a single shaft. Since the driving wheel mainly transmits the bending moment through the transmission shaft, and the weight of the driving wheel is also borne by the transmission shaft, the transmission shaft is easily broken due to fatigue or accidents, making The driving wheel fell to the ground causing an accident. [0004] The broken shaft protection device of the traditional cableway adopts the way of protection outside the wheel, that is, a stop arm is set on the frame of the driving machine, and the end of the stop arm extends i...

Problems solved by technology

But this broken shaft protection method is not reliable. First of all, since there is no other fixing device after the drive shaft is broken, when the driving wheel is blocked by the blocking arm, it will shake around the part blocked by the blocking arm, and the protection is unstable. Second, since the entire weight of the drive wheel and its related components will be borne by the arm after the drive shaft breaks, the arm is easily damaged or falls off, thus failing to provide reliable protection against broken shafts.

In addition, the response time of the outer wheel protection method is long, and the volume of the driving machine increases after the stop arm is installed, the required installation space is large, and the shape is uncoordinated
