EMERGENCY STOP DEVICE FOR CONSTRUCTION VEHICLE, AND CONSTRUCTION VEHICLE
To provide an emergency stop device for construction vehicle which can perform an emergency stop operation of a vehicle in an emergency and which can be retrofitted to a vehicle.SOLUTION: An emergency stop device for a construction vehicle which controls a brake device 20 by a tilting operation of a brake pedal 21 comprises: obstacle detection means 10A detecting an obstacle; and a brake auxiliary device 40 controlling the brake device 20 based on a signal from the obstacle detection means 10A. The brake device 20 and the brake auxiliary device 40 rotate in cooperation with the tilting operation of the brake pedal 21 to share a shaft 27 capable of operating the brake device 20. The brake auxiliary device 40 includes: a second hydraulic cylinder 41 moving forward/backward based on a signal from control means 12; a flexible belt portion 53 one end of which is fixed to a vehicle side and the other end of which is fixed to a tip of the second hydraulic cylinder 41; and a cooperation portion 61 with which the belt portion 53 cooperates and which rotates the shaft 27 by forward/backward movement of the second hydraulic cylinder 41.SELECTED DRAWING: Figure 1
【課題】緊急時における車両の緊急停止動作を行い得る後付けして車両に備えることの可能な建設車両用の緊急停止装置を提供する。【解決手段】ブレーキペダル２１の傾動作動によって制動装置２０を制御する建設車両用の緊急停止装置で、障害物を検出する障害物検出手段１０Ａと、障害物検出手段１０Ａからの信号に基づいて制動装置２０を制御する制動補助装置４０と、を備え、制動装置２０と制動補助装置４０とは、ブレーキペダル２１の傾動作動に連携して回動作動することで制動装置２０を操作可能な軸２７を共用し、制動補助装置４０は、制御手段１２からの信号に基づいて前後進作動する第二油圧シリンダ４１と、一端が車体側に固定されると共に、他端が第二油圧シリンダ４１の先端に固定された柔軟性を有するベルト部５３と、ベルト部５３が連携し、第二油圧シリンダ４１の前後進作動によって軸２７を回動作動させる連携部６１と、を含む。【選択図】図１
