The utility model aims at providing a handcart cubical switchboard with emergent blocking device of pair in order to solve the problem that exists among the above-mentioned current handcart cubical switchboard actual operation.
The utility model has the following concrete scheme: a handcart switch cabinet with a duplex emergency locking device comprises a cabinet body, wherein an opening button and a closing button are arranged on the outer side of the cabinet body, the inner ends of the opening button and the closing button are electrically connected with an air switch in the cabinet body, a disconnecting link operating hole is also arranged on the outer side of the cabinet body, a driving shaft connected with a disconnecting link is arranged in the disconnecting link operating hole, a protective sleeve is sleeved outside the opening button, the inner end of the protective sleeve is fixedly connected with the cabinet body, a penetrating jack is arranged on the side wall of the protective sleeve, an extractable plug pin is arranged in the jack, the plug pin is separated from the opening button by a certain distance, a detachable cover is arranged at the outer end of the protective sleeve, a pressure spring is arranged on the inner side of the cover, and the pressure spring; the cabinet body is provided with a lock catch which can be opened and closed and is arranged at the position of the knife switch operation hole, the lock catch is provided with a padlock, and the bolt is provided with a key for opening the padlock.
The latch is self-opened the key of the padlock.
The protective sheath outer end inner wall is equipped with the internal thread, lid inner is equipped with external screw thread pipe, external screw thread pipe the external screw thread with the internal thread matches.
The inner of pressure spring is equipped with to hit the piece and is used for striking separating brake button.
Switch handle hole outer end is equipped with direction of rotation indicator mark.
The working principle of the utility model is as follows: if the emergency needs to be broken, the operation and maintenance personnel must firstly draw the bolt out of the protecting sleeve, the collision block at the front end of the pressure spring automatically collides the opening button after the bolt is drawn out to perform opening operation, then the operation and maintenance personnel can shake out the handcart operation by holding the key on the bolt or taking the bolt as the key to open the padlock, so that the sequence is realized in the procedure, and misoperation cannot occur; after the fault is cancelled, the padlock is locked, then the cover is detached, the bolt is inserted, the opening button is reset, and finally the cover is arranged on the protecting sleeve for the next operation.
The utility model discloses following beneficial effect has: 1. the switching-off button and the disconnecting link are operated to realize sequential operation on a program, so that the loss caused by misoperation of directly shaking off the handcart without switching-off in advance is avoided; 2. set up protecting pipe and lid on the separating brake button, the mistake can not appear touching the separating brake button and lead to the loss that the adjustment caused during normal operating.
