Abstract
The utility model discloses a locking device of a locomotive high-voltage electric appliance screen cabinet door. The locking device of the locomotive high-voltage electric appliance screen cabinet door comprises a latch blocking rod, a latch link stopper and a plug-in device, wherein one lateral face of the latch link stopper is fixedly connected with a stand column which is arranged on one side of a screen cabinet, one end of the latch blocking rod penetrates through a fixed hole in the latch link stopper, the other end of the latch blocking rod is fixedly connected with the plug-in device, and the back of the plug-in device is fixedly connected with a stand column which is arranged on the other side of the screen cabinet. The locking device of the locomotive high-voltage electric appliance screen cabinet door aims at the requirement of a high-voltage interlocking function of a locomotive high-voltage electric appliance screen cabinet and solves the problem that an operational gap of sides of the screen cabinet of an electric appliance becomes smaller and smaller, the locking device with a front pulling type structure is adopted, and the locking device of the locomotive high-voltage electric appliance screen cabinet door solves the problem that an existing locking device is not convenient to operate due to the fact that the operational gap between screen cabinets is small, and has strong operability.
Description
Technical field
The utility model relates to a kind of locking device, particularly a kind of locomotive high-voltage electrical appliance screen cabinet door locking apparatus.
Background technology
For guaranteeing that locomotive inner high voltage equipment is in electroless state; prevent that maintenance or operating personnel's maloperation from causing high-tension apparatus charged and cause personal injury, the high-voltage electrical apparatus parts such as locomotive high-voltage electrical appliance screen cabinet, pantograph and high voltage isolator all are equipped with the locking device with high voltage interlock function.Existing screen cabinet door lock closes the apparatus structure schematic diagram and sees Fig. 1, the door shelves gripper shoe of this locking device is fixed on screen cabinet right side, when using this locking device, need left and right sides translation bolt lever, because the operating space that requires is larger, and along with the increase of equipment between machinery and the restriction of locomotive size, apparatus arrangement is more and more compacter, gap between electrical appliance screen cabinet is more and more less, and existing locking device is not easy to operate in the confined space.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of locomotive high-voltage electrical appliance screen cabinet door locking apparatus, the defective that the existing locking device of solution is not easy to operate in the confined space.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of locomotive high-voltage electrical appliance screen cabinet door locking apparatus, comprise bolt lever, bolt link stopper, plug together device, a side of described bolt link stopper is fixedly connected with the positive heel post of screen cabinet, described bolt lever one end passes the fixing hole on the bolt link stopper, the described bolt lever other end with plug together device and be fixedly connected with; The described device back side that plugs together is fixedly connected with screen cabinet front opposite side column.
As preferred version, the described device that plugs together comprises lock body, lock body installing plate, door shelves gripper shoe, described lock body is fixed on the lock body installing plate, described lock body installing plate is fixedly connected with the bolt lever, described door shelves gripper shoe be provided with lock body on the shelves pin of pin-and-hole coupling, the one side of described door shelves gripper shoe is fixedly connected with the positive heel post of screen cabinet, and described door shelves gripper shoe another side is connected with lock body by the shelves pin.
Compared with prior art, the beneficial effect that the utility model has is: but the utility model is for the high voltage interlock functional requirement of locomotive high-voltage electrical appliance screen cabinet and the more and more less problem of operating clearance of electrical appliance screen cabinet side, adopt a kind of locking device of front pulling structure, solve existing locking device because of the little problem that is not easy to operate of operating clearance between the screen cabinet, had stronger operability.
Description of drawings
Fig. 1 is existing locomotive high-voltage electrical appliance screen cabinet door locking apparatus structural representation;
Fig. 2 is the utility model one example structure schematic diagram.
The specific embodiment
As shown in Figure 2, the utility model one embodiment comprises lock body 1, bolt lever 3, bolt link stopper 4, door shelves gripper shoe 5, door shelves gripper shoe 5 be provided with lock body on the shelves pin 6 of hole coupling; Described lock body 1 is welded on the bolt lever 3 by lock body installing plate 2,4 one sides of described bolt link stopper are fixedly connected with screen cabinet frontal left column, the one side of described door shelves gripper shoe 5 is fixedly connected with the positive right side of face column of screen cabinet, described door shelves gripper shoe 5 another sides are connected with lock body 1 by shelves pin 6, described bolt lever 3 passes the fixing hole on the bolt link stopper 4, and the grounding nut seat 7 on the door lock gripper shoe 5 can be realized the good earth of locking device and cabinet.
Backing pin 6 on lock body 1 and the door shield gripper shoe 5 is used for realizing interlock.When lock body 1 was connected with door shield gripper shoe 5, it is spacing that the backing pin 6 on the door shield gripper shoe 5 can back down the dead bolt of lock body 1, and namely the supporting key of rotatable and lock body is fixed on locking device on the screen cabinet door, restriction screen cabinet door pull out operation, locking screen cabinet door.
The y that bolt block 4 can limit bolt lever 3 to, z to movement and rotary freedom; The x of lock body 1 that door shield gripper shoe 5 can limit door lock to, y to, z to movement and rotary freedom, the x that namely defines the lock body 1, lock body installing plate 2 of door lock and the assembly that bolt pin 3 forms to, y to, z to movement and rotary freedom, thereby make locking device be completely fixed in the cabinet section in front of the door of screen cabinet, stoped the operation of pulling out of screen cabinet door.
