Rope running alarm and protection device for the endless rope continuous tractor at the slope change point

Abstract

The invention discloses an up grade change point rope running warning protector of an endless-rope continuous towing vehicle. A pair of T-shaped rope pressing wheels opposite to each other in a staggered manner is mounted on bases; the wheel shafts of the T-shaped rope pressing wheels sleeve a rope pressing wheel base plate and are limited by use of nuts mounted on the wheel shaft; the wheel shafts are capable of moving on the rope pressing wheel base plate; an oscillating arm is mounted on the lower side surface of the rope pressing wheel base plate; the oscillating arm is mounted on an oscillating arm rotating shaft; the two ends of the oscillating arm rotating shaft are fixed on the bases; a tension spring mounting rod is arranged on the base; one end of a tension spring is fixed on the tension spring mounting rod, while the other end of the tension spring is fixed on the oscillating arm; on the rope pressing wheel base plate, sensors are mounted on the lower ends of the opposite T-shaped rope pressing wheels. The up grade change point rope running warning protector has the following technical effects that when the towing rope of the endless-rope continuous towing vehicle runs at the up grade change point, in other words, the towing rope separates from the position between the T-shaped rope pressing wheels opposite to each other in the staggered manner and the T-shaped rope pressing wheels slide down under the effect of gravity to trigger the sensors, the sensors transmit stopping signals to realize emergency shutdown; the protector is simple in structure and stable and reliable in signal detection quality, and therefore, the purpose of guaranteeing safe and normal operations of the equipment is realized.

Description

technical field [0001] The invention relates to a running rope protection device for an endless rope continuous tractor. Background technique [0002] As a kind of mining rail transportation equipment, the endless rope continuous tractor is now used more and more in coal mines, and more and more safety protections are required. It is easy to run the rope and cause safety accidents. The current domestic use of the rope running protection device relies on detecting whether the rope pressing wheel rotates. When the rope is running, the rope pressing wheel does not rotate anymore. The tractor is protected to stop. This method cannot detect the running rope when the endless continuous tractor stops normally. Contents of the invention [0003] The purpose of the present invention is to provide a running rope protection device for an endless rope continuous tractor. [0004] The technical solution of the present invention is an alarm protection device for rope running at the sl...
