External tooth drive sheave device for endless rope continuous tractor

Abstract

The invention discloses an external gear type drive rope wheel device of an endless rope continuous towing vehicle. A drive shaft is arranged on a drive rope wheel body; a drive gear is fixed on the drive rope wheel body; a wheel lining is fixed on the outer ring of the drive rope wheel body through bolts; the drive shaft comprises a middle part connected with the drive rope wheel body, and two tip parts; the diameter of the middle part is larger than that of each of the two tip parts; the inner bore diameter of an end cover is the same as that of each of the two tip parts; the end cover is fastened on a wheel core of the drive rope wheel body through bolts, and thus the drive rope wheel body and the drive shaft are fixed. According to the external gear type drive rope wheel device, the drive rope wheel body and the drive shaft are fixed by adopting the end cover, so that a fixation mode adopting a positioning shaft sleeve is replaced, and thus the processing technology is simple, the processing difficulty is reduced, and meanwhile the drive rope wheel body is effectively prevented from axially shifting on the drive shaft. A braking disc is arranged to be matched with other brakes, so that the wheel side braking of the drive rope wheel body is realized; when the endless rope continuous towing vehicle is in operation, if a runaway slip accident or a high-speed brake failure happens, the drive rope wheel body can be fast clamped, so that the whole system immediately stops running, and thus the traffic safety of the endless rope continuous towing vehicle can be ensured.

Description

technical field [0001] The invention relates to an external tooth type drive sheave of an endless rope continuous traction vehicle. Background technique [0002] The driving sheave device is an important part of the driving device of the endless rope continuous tractor. The steel wire rope is wound on the driving sheave, and the motor drives the driving sheave to rotate. reciprocating motion in the system. Therefore, the rope reel controls the safe operation of the wire rope to a certain extent. [0003] At present, due to the complexity of the underground mine tunnel, when the shuttle car is continuously pulled by the endless rope to transport large-tonnage minerals, it will cause the swing or shaking of the steel wire rope, resulting in axial movement of the rope winding wheel body and mutual wear of parts. The service life of the equipment is reduced, and it is also easy to cause potential safety hazards. In order to solve this problem, the traditional method is to ins...

Problems solved by technology

[0003] At present, due to the complexity of the underground mine tunnel, when the shuttle car is continuously pulled by the endless rope to transport large-tonnage minerals, it will cause the swing or shaking of the steel wire rope, resulting in axial movement of the rope winding wheel body and mutual wear of parts. Reduce the service life of the equipment, but also easily cause safety hazards

In order to solve this problem, the traditional method is to install a positioning sleeve on the bearing to withstand the end face of the driving sheave body to achieve positioning. However, this positioning method requires high processing accuracy on the two ends of the positioning sleeve and the shaft hole, which is not easy. accomplish

[0004] At the same time, because the external gear driving device has safer and more stable driving performance than the direct-coupled drive, it is widely used, but the current external gear driving wheel cannot be equipped with wheel brakes. When the endless rope continuous tractor When an accident such as speeding occurs, it is usually necessary to use the high-speed brake installed at the power output end to implement emergency braking to ensure the driving safety of the endless rope continuous tractor. If the high-speed brake fails and emergency braking cannot be performed, it may also cause safety hazards
