Lift car can be locked in elevator by pin plate insertion pin hole, but existing locking device is relatively simple, is easy to appear
Maloperation has safety hazards.
Utility model content
In order to solve the above technical problems, the electricity high and convenient for operation the purpose of the utility model is to provide a kind of safety coefficient
Terraced locking device.
The technical solution adopted in the utility model is:
A kind of elevator locking device, including mounting base and bolt are offered in the mounting base and are passed through for bolt and energy
The through-hole enough moved left and right is additionally provided with fixed bayonet in the mounting base, and the upper end edge bolt of the fixation bayonet moves left and right
Direction offer elongated hole, the fixture block matched with fixed bayonet is provided on the bolt, which can be in fixing card
It is moved up and down in mouthful so that bolt is rotated with central axis, and can be moved left and right in elongated hole to drive bolt or so to move
In the dynamic pin hole to insert or pull out elevator inner sidewall.
Limit switch is additionally provided in the mounting base as a further improvement of the utility model, is gone back on the bolt
It is provided with the recess portion matched with limit switch, the safety circuit in the limit switch and external lifts is electrically connected.
The fixed bayonet is provided with two as a further improvement of the utility model, the respectively first fixed bayonet
With the second fixed bayonet, the both ends of elongated hole are connected to the upper end of the upper end of the first fixed bayonet, the second fixed bayonet respectively.
The high coating of coefficient of friction is provided on the fixture block as a further improvement of the utility model, in order to hand
It holds.
The utility model has the beneficial effects that
The utility model compared with prior art, is efficiently avoided because the bolt is not in place, and is occurred described slotting
Pin is not inserted into in pin hole or in pin hole but not deep enough phenomenon, is reduced the possibility of malfunction, be ensure that construction personnel
Safety.
Detailed description of the invention
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram at another visual angle of the utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of elevator locking device, is arranged on the frame 8 of elevator car roof, including installation
Seat 1 and bolt 2, offers the through-hole that passes through and can move left and right for bolt 2 in the mounting base 1, in the mounting base 1
It is additionally provided with fixed bayonet 3, the direction that the upper end edge bolt 2 of the fixation bayonet 3 moves left and right offers elongated hole 4, described to insert
The fixture block 5 matched with fixed bayonet 3 is provided on pin 2, which can move up and down in fixed bayonet 3 so that bolt 2
It is rotated, and can be moved left and right in elongated hole 4 to drive bolt 2 to move left and right to insert or pull out elevator with central axis
In the pin hole of well inner sidewall.Compared with prior art, it efficiently avoids because the bolt 2 is not in place, and occurs described slotting
Pin 2 is not inserted into in pin hole or in pin hole but not deep enough phenomenon, is reduced the possibility of malfunction, be ensure that construction personnel
Safety.
Further, it is additionally provided with limit switch 6 in the mounting base 1, is additionally provided on the bolt 2 and limit switch 6
Safety circuit in the recess portion 7 matched, the limit switch 6 and external lifts is electrically connected, when limit switch 6 detects recess portion
It can just be resetted when 7, safety circuit, which is adopted, after reset to connect, and elevator could operate normally, and further enhance safety.
As preferred embodiment, there are two the fixed settings of bayonet 3, and the respectively first fixed bayonet 31 and second is solid
Determine bayonet 32, the both ends of elongated hole 4 are connected to the upper end of the upper end of the first fixed bayonet 31, the second fixed bayonet 32 respectively, with
It is convenient for locking operation or terminates locking operation, fixture block 5 can be located in corresponding fixed bayonet 3, keep operation more accurate
Conveniently.
The high coating of coefficient of friction is provided on the fixture block 5 in order to hold.
The working principle of the utility model is: push bolt 2 to be moved to the left by elongated hole 4 when carrying out locking operation, it is recessed
Limit switch 6 is left in portion 7, and safety circuit disconnects, and elevator stops operation, elevator bolt 2 be inserted into pin hole after by fixture block 5 to moving down
It is dynamic to be fixed in bayonet 31 so that fixture block 5 is locked at first；When stopping locking operation, fixture block 5 is moved up, is pushed away by elongated hole 4
Dynamic bolt 2 moves right, and recess portion 7 contacts limit switch 6, safety circuit conducting, and elevator is able to carry out normal work, then will card
Block 5 is locked in the second fixed bayonet 32, is stopped locking operation and is completed.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the utility model aim technical solution belong to the protection scope of the utility model it
It is interior.
