Description
Technical field
The present invention relates to the coal mine operation equipment technical field, relate in particular to a kind of rotating stop device of output shaft of circuit breaker.The invention still further relates to a kind of downhole operation equipment with above-mentioned rotating stop device of output shaft of circuit breaker.
Background technology
Power consumption equipment in the downhole operation equipment all has higher requirement of explosion proof, before entering underground work, all need carry out explosion-proof processing.As the circuit breaker of development machine, circuit breaker is arranged in the electric cabinet, in order to make the setting of circuit breaker meet requirement of explosion proof, need be provided with one usually and be enclosed within the electric cabinet spanner mechanism of operating breaker outward.
Spanner mechanism comprises rotating shaft and spanner, described rotating shaft is passed the door-plate of electric cabinet and is formed explosion suppresion surface with the door-plate of electric cabinet, one end of described rotating shaft is connected with the output shaft of circuit breaker, the other end is positioned at the outside of electric cabinet, spanner is connected with the outboard end of rotating shaft, and operating personnel can realize connection, the opening operation of circuit breaker by the spanner rotating shaft.Because operating personnel's misoperation often makes the excessive rotation of spanner, even the excessive rotation of rotating shaft, also be that circuit breaker has arrived and still continues rotary spanner after being switched on or switched off the position, to make the inner rotary handle part of circuit breaker by rounding like this, and perhaps make the output shaft of circuit breaker rupture, thereby cause purpose of breaker failure, the maintenance personal has to open electric cabinet in the down-hole, change circuit breaker, open electric cabinet, have serious potential safety hazard in the down-hole.
In order to prevent the excessive rotation of rotating shaft, the rotation amount of a position-limit mechanism with the restriction spanner need be set.Usually the outboard end in rotating shaft is provided with a sheath, sheath is welded on the outside of electric cabinet door-plate, sheath is provided with the cannelure that the rotating distance with circuit breaker adapts, the spanner fixing with the rotating shaft outboard end is stuck in this cannelure, spanner can rotate in this cannelure, the opening angle of cannelure can limit the position of rotation up and down of spanner, prevent the excessive rotation of spanner thereby play, and then can prevent the inner rotary handle of circuit breaker because of excessive rotation by rounding, also can avoid the output shaft of circuit breaker to rupture because of excessive rotation.
But this position-limit mechanism is positioned at the outside of electric cabinet, and development machine is operated in the down-hole, and operating mode is relatively poor, and the rock that falls in the course of work very easily smashes sheath, thereby makes the rotation of spanner lose restriction, can't play the effect of the excessive rotation of restriction spanner; Because sheath is positioned at the outside of electric cabinet, can be removed easily, operating personnel are for easy to operate, the sheath that just will be welded on the door-plate outside before development machine is gone into the well slices off, be enclosed within the rotating shaft with homemade spanner, homemade pinch bar length is longer than the spanner that electric cabinet carries, when operation, apply connection, disconnection action that less power just can realize circuit breaker, make the excessive rotation of rotating shaft easilier like this, can cause the suffered moment of torsion of output shaft of circuit breaker excessive, repeatable operation will cause circuit breaker to carry the damage of rotating mechanism.
In addition, because foozle, the actual anglec of rotation of the output shaft of circuit breaker and the specified anglec of rotation be deviation slightly, and the opening angle of the cannelure of sheath must satisfy the maximum anglec of rotation of output shaft, so that the output shaft of circuit breaker can be in required operating mode position, thereby the opening angle of the cannelure of sheath is greater than the specified anglec of rotation stroke of output shaft of circuit breaker, thereby make the output shaft of circuit breaker still can have the problem of excessive rotation, and do not have the effect of the excessive rotation of restriction rotating shaft.
