Description

A kind of anti-misoperation locking lock body of horizontal installation

Technical field

The utility model relates to a kind of anti-misoperation locking lock body that is used for preventing faulty operation of electric power system, especially can electromagnetic lock be installed thereon, itself can adopt the lock body that laterally is installed on the substation equipment.

Background technology

At present microcomputer anti-error operating system has been widely used in the transformer station, power plant of power system.Lockset in the anti-misoperation system mostly is mechanical lock greatly, can be by equipment such as electric or mechanical system locking switch, disconnecting link (cutter), pile and net doors.But mechanical lock can only simply lock, virtual condition that can not checkout equipment, switching lock state that can not detection itself.Because this type of deficiency uses the microcomputer anti-error operating system of this lockset just to have a serious deficiency, that is: when carrying out on-the-spot switch operation, device physical status is not known by system, does not know the open and-shut mode of lockset yet.All states can only rely on artificial judgement, and the very big possibility of makeing mistakes is arranged, as: just only release and do not have operation carry out next step operation of current device, this situation is become " do-nothing operation ", and consequence is device damage, personal injury often; Current device operation back is non-latching, and this situation is become " empty locking ", causes equipment to be in no blocking, in case by malfunction, consequence is also very serious.Use can not checkout equipment virtual condition, the anti-misoperation system of the lockset of switching lock state that can not detection itself can only be finished " five is anti-" function of discounting.

Summary of the invention

For the lockset that solves present anti-misoperation system can not the checkout equipment state and open and close the problem of lock state, the utility model provides a kind of anti-misoperation locking lock body of horizontal installation, its technical scheme of taking is: this lock body comprises lock, lock pin, spring and handgrip, the end face of lock has the electromagnetism locked groove that can place the electromagnetic lock lock body, the side of lock has the circular groove of placing spring, the another side has the elongated slot of placing handgrip, the vertical section of elongated slot is shaped as the borehole structure that radial position has prominent groove, handgrip part vertical section near the elongated slot port is shaped as the circular ring structure that radial position has projection, can with the elongated slot tabling, there is the less circular hole of a diameter to be communicated with between elongated slot and the circular groove, have annular recess on the partial sidewall of insertion elongated slot in the handgrip, there is a through hole at the handgrip center, through hole is positioned at the diameter of the outer part of elongated slot greater than the diameter that is positioned at the elongated slot part, the width of groove is slightly larger than the end face diameter of electromagnetic lock dead bolt, lock pin passes circular groove and handgrip and snaps onto on the inwall of the larger-diameter throughhole portions of handgrip than the throughhole portions of minor diameter, being enclosed within Spring Card on the lock pin is connected between the inwall of be coupling place and circular groove of lock pin, when the lockset locking, the electromagnetic lock dead bolt stretches out and passes the electromagnetism locked groove and is stuck in the groove, this moment, lock pin kept stretching out state, when lockset is unblanked, the withdrawal of electromagnetic lock dead bolt, handgrip is drawn out and rotates to an angle, make projection on the handgrip be stuck in the outer wall of elongated slot, this moment, lock pin kept retracted mode.

This lock body cooperates with the electromagnetic lock of installing thereon, can the checkout equipment state; Lock body adopts fixed form to be installed on the equipment, has to lock advantages such as firm; Lock body has certain flexible surplus at the blocking lock pin, can avoid the improper lock pin that causes in installation site stuck.Therefore this lock body have easy to use, install firm, detect characteristic of accurate.

The specific embodiment

Below in conjunction with accompanying drawing to describing in detail with embodiment the utility model:

As shown in Figure 1, use screws or thread bush to be fixed on the substation equipment lock body is fastening, realize locking substation equipment by lockset fixing hole 6.The end face of lock 1 has the electromagnetism locked groove 4 that can place electromagnetic lock lock body 11, electromagnetic lock lock body 11 uses hold-down screw to be fixed on the lock by electromagnetic lock fixing hole 5, the side of lock 1 has the circular groove 20 of placing spring 2, and the another side has the elongated slot 17 of placing handgrip 7.As shown in Figure 4, the vertical section of elongated slot 17 is shaped as the borehole structure that radial position has prominent groove, is shaped as the circular ring structure that radial position has projection near the handgrip 7 part vertical sections of elongated slot 17 ports, can with elongated slot 17 tablings.As shown in Figure 3, have annular recess 18 on the partial sidewall of insertion elongated slot 17 in the handgrip 7, the width of groove 18 is slightly larger than the end face diameter of electromagnetic lock dead bolt 10, there is the less circular hole of a diameter to be communicated with between elongated slot 17 and the circular groove 20, there is a through hole at handgrip 7 centers, through hole is positioned at the diameter of elongated slot 17 outer parts greater than the diameter that is positioned at elongated slot 17 parts, lock pin 3 passes circular groove 20 and handgrip 7 and snaps onto on the inwall of handgrip 7 larger-diameter throughhole portions than the throughhole portions of minor diameter, and can rotate separately between lock pin 3 and the handgrip 7, be enclosed within spring 2 on the lock pin 3 and be connected between the inwall of be coupling place and circular groove 20 of lock pin 3.

As shown in Figure 2, when this lockset is applied in certain type disconnecting link, the thread bush 15 of screwing in the screwed hole on disconnecting link holder 13, and thread bush 15 is inserted in the circular groove 20, and then the hold-down screw of in the thread bush fixing hole 8 of lock 1, screwing on, lockset can be fixed on the disconnecting link.The switch operation handle 12 and the handle lockplate 14 of this disconnecting link weld together, and when operation, switch operation handle 12 is that the center of circle moves in a circle with arm pivot post 16, and when switch operation handle 12 was shifted the top onto, disconnecting link closed; When switch operation handle 12 was moved the bottom to, disconnecting link separately.Screwed hole and shaft hole are arranged on the disconnecting link holder 13, the branch position is arranged on the handle lockplate 14 and close a lock hole, the lock pin 3 of lockset passes in the lock hole that thread bush 15 is inserted into handle lockplate 14, if lockset locking, lock pin can not be withdrawn, then the switch operation handle can be subjected to the lock pin obstruction and can not move, thereby has realized the locking of disconnecting link.

As shown in Figure 3, when the lockset locking, electromagnetic lock dead bolt 10 stretches out and passes in the annular groove 18 that electromagnetism locked groove 4 is stuck in handgrip 7, stops the axially-movable of handgrip 7 in lock 1.This moment, lock pin 3 can not be raised, and lock body is in blocking.Under the effect of back-moving spring 2, lock pin 3 can remain on the state of stretching out.When lockset was in blocking, if receive axial pressure, lock pin 3 can so just can be avoided because equipment extruding lock pin 3, lock pin 3 bites that cause then of causing not in place are installed to a lock body direction withdrawal part.

As shown in Figure 5, when electromagnetic lock was unblanked, 10 withdrawals of electromagnetic lock dead bolt no longer were stuck in the annular groove 18 of handgrip 7, and lock pin 3 can be in the axially-movable in the lock 1.Pull out handgrip 7, lock pin 3 also is drawn out, and lock body is in unlocking condition.At this moment, handgrip 7 is rotated to an angle, make projection on the handgrip 7 be stuck in the outer wall of elongated slot 17, lived by the support structure on the lock, lock pin 3 can remain on retracted mode.
