The invention relates to a horizontal guide wheel with the shaft breakage prevention device; the horizontal guide wheel comprises a guide wheel body, a wheel shaft, a base, a shaft breakage prevention device and a shaft breakage detection switch, the shaft breakage prevention device is fixed to the base, a claw part of the shaft breakage prevention device extends into a clamping groove of the wheel body, a 5 mm gap is kept, rotation of the wheel body is not interfered in the normal state, and when the wheel shaft is broken, the claw part clamps the wheel body, and the wheel body is prevented from falling off or flying out. The whole shaft breakage prevention device is of two semicircular structures, the two semicircular structures are fixed to the guide wheel base through high-strength bolts respectively, and when the guide wheel needs to be overhauled, the shaft breakage prevention device can be detached. In order to prevent the wheel body from continuously rotating after the shaft is broken, a group of U-shaped needles are additionally arranged on the edge of the wheel body in the horizontal direction and the vertical direction respectively to serve as a shaft breaking detection switch, shaft breaking is that the wheel body inclines and breaks the U-shaped needles by collision, a shaft breaking signal is transmitted to a brake controller of the steel wire rope traction equipment, and after the controller detects the shaft breaking, safety braking is started immediately. The device is simple in structure, convenient to disassemble, low in manufacturing cost and good in practicability.
本发明涉及了带防断轴装置的水平导向轮,包括导向轮轮体、轮轴、底座、防断轴装置、断轴检测开关,防断轴装置固定于底座上,防断轴装置的爪部伸入在轮体的卡槽内,保持5mm间隙,正常时,不干涉轮体转动,轮轴断裂时,由爪部卡住轮体,防止轮体脱出或飞出。防断轴装置整体为两个半圆形结构,分别采用高强度螺栓固定导向轮底座上,需要检修导向轮时,可以拆除防断轴装置。为防止轮体在断轴后继续转动,在轮体的边缘水平方向和垂直方向各加装1组U型针作为断轴检测开关,断轴是轮体发生倾斜,撞断U型针,将断轴信号传递至钢丝绳牵引设备制动控制器,控制器检测到断轴后,立即启动安全制动。本装置结构简单、拆卸方便、造价便宜,具有良好的实用性。
