The locking and locking device for the mining feed switch is convenient for really achieving who has power failure and who has power transmission, fundamentally stops power transmission against regulations, and effectively ensures safe production of mines.
Description
Technical Field
The utility model relates to a blocked mechanical system, specific theory has related to a mining feed switch shutting locking device.
Background
The power-on and power-off operation is an important link of electrician operation, and in the process of maintenance of power supply equipment, in order to ensure the safety of maintenance personnel, when a switch has power failure, a switch handle is locked when a power supply is cut off, a warning board is hung, and a person in charge is only allowed to start and stop the switch. However, since the locking mechanism of the power supply apparatus is essentially a lead screw, it can be easily opened by screwing, for example: CN202585183U discloses a locking device for a mining feed switch, which is locked by a locking rod and can be opened only by a screwdriver, so that personal injury caused by power failure and power transmission errors occurs occasionally, and personal safety of production and operating personnel is directly endangered.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
the utility model aims at providing a to the not enough of prior art to a novel mining feed switch shutting locking device is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is:
A locking and locking device of a mining feed switch comprises a mounting plate and lock bodies, wherein one end of the mounting plate is hinged with a lock rod, the other end of the mounting plate is provided with a first groove corresponding to the lock rod, one side wall of the first groove is hinged with one end of a locking connecting plate, the other end of the locking connecting plate and the other side wall of the first groove are correspondingly provided with first lock holes, when the locking connecting plate is rotated until the two first lock holes are overlapped, the locking connecting plate and the first groove surround to form a second lock hole for locking the lock rod, and the free end of the lock rod is bent and provided with a locking rod shielding groove; under the locking state, the lock rod penetrates through the second lock hole, the outer end of the locking rod extends into the locking rod shielding groove, and the lock body locks the first lock hole.
On the basis, one end of the mounting plate is provided with a second groove, two opposite side walls of the second groove are provided with rotating shafts, and one end of the locking rod is hinged to the rotating shafts.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses mining feed switch shutting adds locking device, further locks to mining feed switch's dead lever, during the use, welds the mounting panel to the outer wall in the holding chamber of dead lever on, at first rotates the locking lever when needing to lock, makes the locking lever fall into first recess, and the outer end of dead lever stretches into the dead lever and shields the groove by the dead lever in shielding the groove, rotates the shutting even board again and makes two first lockhole overlaps, locks the lock body at last first lockhole, so do not have the staff of key can't open the shutting lever and stop the power transmission operation to feed electric switch, really do who has a power failure, who power transmission fundamentally stops the power transmission violating regulations, effectively ensures mine safety in production.

Fig. 2 is a left side view schematically illustrating the present invention.
In the figure: 1. mounting a plate; 2. a first lock hole; 3. a lock lever; 4. the locking rod shields the slot; 5. and locking the connecting plate.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-2, a locking and locking device for a mining feed switch comprises a mounting plate 1 and a lock body, wherein one end of the mounting plate 1 is hinged to a lock rod 3, the other end of the mounting plate 1 is provided with a first groove corresponding to the lock rod 3, one side wall of the first groove is hinged to one end of a locking connecting plate 5, the other end of the locking connecting plate and the other side wall of the first groove are respectively provided with a first lock hole 2, when the locking connecting plate is rotated until the two first lock holes 2 are overlapped, the locking connecting plate and the first groove surround to form a second lock hole for locking the lock rod, and the free end of the lock rod 3 is bent and provided with a locking rod shielding groove 4; under the locking state, the lock rod penetrates through the second lock hole, the outer end of the feed switch locking rod is shielded by the locking rod shielding groove, the lock body locks the first lock hole, and a person without the lock body key cannot unlock the lock body.
During the use, weld the mounting panel to the outer wall in the holding chamber of dead lock pole on, at first rotate the locking lever when needing to lock, make the locking lever fall into first recess, the outer end of feed switch dead lock pole stretches into in the dead lock pole shields the groove, rotate the shutting and link the board and make two first lockhole overlaps, locks the lock body at last first lockhole, so do not have the staff of key and can't open the dead lock pole and stop the power transmission operation to feed switch, really do who has a power failure, who power transmission, fundamentally stops the power transmission violating regulations, effectively ensures mine safety in production.
Furthermore, one end of the mounting plate 1 is provided with a second groove, two opposite side walls of the second groove are provided with rotating shafts, and one end of the locking rod 2 is hinged to the rotating shafts.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
