Ore deposit accident；It is interference fit between sealing shroud and steel wire rope, while ensureing that steel wire rope can do relative slip through sealing shroud,
It is greatly possible to prevent methane gas to stretch into inside branch pipe；Spring second is set and provides reset pulling force to steel wire rope, it is to avoid steel wire
Reset capability is not enough in use for rope.
The use step of the present apparatus is：
1）The ratchet accepting hole of depth 2000mm is bored in roadway floor using swinging jumbolter, bit diameter is 28mm；
2）Ratchet is pushed successively in the ratchet accepting hole accomplished fluently in advance, each clamping close device pushes the depth of ratchet accepting hole
Degree is all different, can so measure the pucking amount of roadway floor different depth, and the determination to last Floor Heave in Roadway amount is provided
More sufficient data.Will be according to order during clamping close device is pushed, can not be chaotic, ratchet be able to will finally be housed with ratchet
Hole inwall is caught well；
The other end of pull rope passes through fix bar, by being connected to tensioning apparatus after roll shaft, the ratchet correspondence is connected
Pull rope by tensioning apparatus effect stretch tight, have certain tension force.
3）The encoder and routine being connected with each other are set, after encoder detects roll shaft to be rotated, electric current is produced；
When roadway floor occurs pucking, fix bar produces displacement with respect to ratchet, now pull rope will under tension and with respect to roll shaft
Generation change in location, because pull rope is in spiral shell type groove all the time, pull rope band action roller shaft is relatively rotated, and now encoder is produced
Current signal；
Routine changes according to electric current in accessing circuit, and data processing unit produces electric current letter according to encoder
Number the roll shaft anglec of rotation is drawn, because spiral shell type groove equidistantly extends along roll shaft axis, data processing unit and then extrapolate pull rope
With respect to the movable length of roll shaft, the length of pull rope movement had both been Floor Heave in Roadway amount, and these data can unit records
Get off, it is necessary to when directly invoke.
The device can be monitored and data storage automatically, it is not necessary to which survey crew frequently goes into the well observation, easy to operate, time saving
It is laborsaving.
