The invention discloses a driving safety protection device of an underground trackless auxiliary transport vehicle. A pneumatic control reversing valve is additionally arranged in a vehicle braking system, so that an actuating mechanism can be operated only when the vehicle is in a braking state, and the actuating mechanism does not act even if an operating button is touched accidentally in the driving process. Meanwhile, in order to prevent a driver from engaging a gear to drive the vehicle under the condition that the vehicle door is not closed, a corresponding protection device is additionally arranged in a gear engaging loop, and a door locking valve is triggered to act only after a cab door is closed, so that the gear engaging loop is controlled to take effect, and gear engaging driving is achieved. After the set of driving safety protection device is additionally arranged on the underground trackless auxiliary transport vehicle, the safety driving performance of the vehicle can be effectively improved. The driving safety protection device plays an important role in reducing vehicle operation accidents, and has positive significance in guaranteeing the personal safety of underground operating personnel.
本发明公开了一种井下无轨辅助运输车辆的行车安全防护装置,通过设置在车辆制动系统中增添设置气控换向阀,确保执行机构只有在车辆处于制动状态时才能进行操作,行车过程中,即使不慎触碰了操作按钮,执行机构也不会有动作。同时为避免驾驶人员没有关好车门的情况下就挂挡行车,在挂挡回路中增加了相应的保护装置,只有在驾驶室门关上后,会触发门闭锁阀动作,从而控制挂挡回路生效,实现挂挡行车。在井下无轨辅助运输车辆上增加该套行车安全防护装置后,可有效提高车辆的安全行驶性能,对降低车辆运行事故有重要作用,对保障井下作业人员的人身安全有积极意义。
