The upper pulling winch is connected with a guide roller and the guide roller matches with a transmission cylinder for using. The advantages: 1. The utility model can make the hoist operate in the interior lateral bending tunnel to realize the continuous transport. 2. The drag guiding vehicle enjoys reasonable structure, peculiar method of operation, small size, light in weight, convenient field erection, decreased link of the mine section transport, fewer people to raise the effect and raised conveying efficiency. 3. The '8' shaped binding of the upper drive roller of the steel cable increases the wrap angle between the steel cable and the drive roller and increases the circumferential driving force of the drive roller and reduces the grind of the drive roller and the steel cable to prolong the service life and to decrease the material consumption.
