Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] An escape shaft is arranged in the tunnel, and the escape shaft is used for escape in the event of an emergency, and the escape shaft communicates with the outside world through an underground passage. The well cover of the escape well is also used as a traffic road at ordinary times, so the well cover of the escape well is usually made of metal or cement, and the weight of the well cover is very large. The present invention mainly improves the installation structure and opening method of the manhole cover, which will be described in detail below.
[0025] The tunnel escape shaft 300 includes a well cover 100 , a lever assembly 400 and a counterweight system. The lever assembly 400 is fixed on the well cover 100 , and the counterweight system is connected to the lever assembly 400 . A well frame 101 is secretly covered on the wall body...

The invention discloses a counterweight system of a tunnel escape well and the tunnel escape well. The tunnel escape well comprises a well cover, a lever assembly and the counterweight system. The lever assembly is fixed to the well cover, and the counterweight system is connected with the lever assembly; the counterweight system of the tunnel escape well comprises a counterweight block connectedwith the well cover through a first traction rope and a driving mechanism connected to the counterweight block, and the driving mechanism comprises a second traction rope and a hand-operated type tractor which are connected to the counterweight block, and the hand-operated type tractor realizes the lifting and dropping height of the counterweight block by controlling the stretching and shrinking length of the second traction rope; and in the emergency event, operators release the traction rope through the tractor and lowers the counterweight block so as to open the well cover of the tunnel escape well, so that personnel can escape from the tunnel escape well. The counterweight system of the tunnel escape well and the tunnel escape well have the advantages of low installation and maintenance costs, good reliability and the like.
Description
technical field [0001] The invention relates to a tunnel escape shaft, in particular to a tunnel escape well cover counterweight system and a tunnel escape shaft. Background technique [0002] The tunnel escape shaft is used for the escape of personnel when an emergency occurs in the tunnel. When an emergency occurs such as landslide, flooding, explosion, etc., the escape shaft communicates with the outside world through an underground passage. [0003] Chinese application publication number is CN108104173A tunnel escape manhole cover installation structure and tunnel escape well, including manhole cover, counterweight system and locking system are connected on the manhole cover, counterweight system always provides a force for the opening of manhole cover, and locking system is used to overcome counterweight The active force provided by the system keeps the manhole cover closed; when the locking system is released, the active force provided by the counterweight system opens...
