Tunnel escape well lid and tunnel escape well
The invention provides a tunnel escape well lid and a tunnel escape well. The tunnel escape well lid comprises a well lid frame, an upper lid and a driving device, wherein one end of the upper lid isrotationally connected with the well lid frame, and the driving device drives the upper lid to rotate. The driving device comprises a manual jack, an operating handle of the manual jack is connected with a driving mechanism for driving the operating handle to swing, the driving mechanism comprises a sliding rod connected with the bottom of the upper lid in a sliding mode, a push rod capable of abutting against the operating handle is fixedly connected to the sliding rod, a first connecting rod and a second connecting rod are further rotationally connected to the sliding rod; the first connecting rod is rotationally connected with an upper lever rotationally connected with the upper lid, and the second connecting rod is rotationally connected with a lower lever rotationally connected with the upper lid; and the sliding rod is further connected with a spring bolt matched with a lock groove of the well lid frame in a far-away mode,and the spring bolt is in a locked state and an unlocked state by enabling the sliding rod to slide. The tunnel escape well lid provided by the invention has a self-locking function, can be opened on the upper side and the lower side of a well and can stillbe opened under the condition of no electric power, so that the reliability is improved.
本发明提出了一种隧道逃生井盖和隧道逃生井，所述的隧道逃生井盖包括井盖框架、一端与井盖框架转动连接的上盖、以及驱动上盖转动的驱动装置；驱动装置包括手动千斤顶，手动千斤顶的操作手柄连接有驱动其摆动的驱动机构，驱动机构包括与上盖底部滑动连接的滑杆，滑杆上固定连接有能够与操作手柄抵触的推杆，滑杆上还转动连接有第一连杆和第二连杆，第一连杆转动连接有与上盖转动连接的上杠杆，第二连杆转动连接有与上盖转动连接的下杠杆；滑杆远离上还连接有与井盖框架的锁槽配合的锁舌，滑动滑杆使锁舌处于锁止状态和解锁状态。本发明的隧道逃生井盖具有自锁功能，而且能够实现井上井下两侧开启，而且在无电力情况下，仍可开启，增加可靠性。
