It can be rotated along vertical plane, rotational angle is at least 90 °, is rotatably horizontality and plumbness；When block is rotated in level
When state, in upright projection, block and carriage have overlapping；When block rotation is in plumbness, in upright projection, block
It is not overlapped with carriage and distance is greater than 1cm；Have that horizontal drawing spring upper end is fixed on stop bottom, lower end is fixed on crossbeam side, it is horizontal
Draw spring block can be pulled to horizontality；Block side is fixed with Electromagnetic lock, and the lock core of Electromagnetic lock can fix block
In plumbness.
The block is rotatably fixed on the shaft fixed block of block two sides, and shaft fixed block is fixed on the upper table of crossbeam
Face.
The block and the horizontal fixed point drawn between spring are located on block bottom surface close to the position of rotation outer end.
It has been wholely set on the block bottom surface and has been downwardly projected auxiliary spacer block.
The block thickness is greater than 4cm, and the height of spacer block is assisted to be greater than 3cm.
The section of the auxiliary spacer block is triangle, and auxiliary spacer block lower end tip is arc-shaped.
The auxiliary spacer block is integrally formed with block.
The utility model has the beneficial effects that: by block, the horizontal structure setting for drawing spring and Electromagnetic lock, and be based on
The electrical characteristic that the energization of Electromagnetic lock is opened, being aided with the common acceleration relay of the prior art may make under prevention carriage
The safety measure fallen can be independent of control system, so that effectively avoiding carriage high speed from falling causes serious casualties.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged diagram of block in Fig. 1.
In figure: 11- carriage, 12- stringer, 13- crossbeam, 21- block, the horizontal drawing spring of 22-, 23- shaft fixed block, 24- electricity
Magnetic lock, 25- tapered end fixed block, 26- assist spacer block.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
A kind of damage type elevator safety supplementary structure as shown in Figure 1 and Figure 2, the crossbeam 13 including elevator；The elevator
The upper surface of the crossbeam 13 of well is equipped with block 21, and 21 face carriage 11 of block；The quantity of block 21 in every layer of crossbeam 13 to
There are three few；Block 21 can be rotated along vertical plane, and rotational angle is at least 90 °, be rotatably horizontality and plumbness；When
Block 21 is rotated in horizontality, and in upright projection, block 21 and carriage 11 have overlapping；When block 21 is rotated in vertical configuration
When state, in upright projection, block 21 and carriage 11 are not overlapped and apart from greater than 1cm；There is horizontal 22 upper end of drawing spring to be fixed on gear
21 bottom of block, lower end are fixed on 13 side of crossbeam, and block 21 can be pulled to horizontality by horizontal drawing spring 22；21 side of block is fixed
There is Electromagnetic lock 24, block 21 can be fixed on plumbness by the lock core of Electromagnetic lock 24.
Electromagnetic lock 24 is fixed on the tapered end fixed block 25 of 21 side of block as a result, is controlled by acceleration relay
It is powered, acceleration relay is fixed in carriage 11, when 11 acceleration of carriage is greater than acceleration relay preset parameter value, is added
Speed relay makes Electromagnetic lock 24 be powered, then the lock core of Electromagnetic lock 24, which is shunk, completes to unlock, and block 21 is in horizontal drawing spring 22
Under the action of turn to horizontality, collide during carriage 11 declines with block 21, block 21, which plays, slows down carriage 11
The effect of decrease speed, if 11 decrease speed of carriage is too fast, block 21 is destroyed, and carriage 11 continues to decline by next layer
Block 21 is stopped, thus until there is block 21 to hold carriage 11, so that the straight elevator bottom of carriage 11 be avoided to cause people
Member's injures and deaths.
As the preferred embodiment of 21 fixed form of block, the shaft that the block 21 is rotatably fixed on 21 two sides of block is solid
Determine block 23, shaft fixed block 23 is fixed on the upper surface of crossbeam 13.
Block 21 is pulled to horizontality since the horizontal effect for drawing spring 22 is only that, is only needed under normal circumstances lesser
Pulling force, therefore to further decrease required horizontal 22 pulling force of drawing spring, to further reduce the cost, the block 21 and horizontal drawing bullet
Fixed point between spring 22 is located on 21 bottom surface of block close to the position of rotation outer end.
Further, when block 21 works, stress point is in 21 bottom of block between block 21 and crossbeam 13, it is clear that
Stress point is bigger, then blocking effect is better, therefore has been wholely set on 21 bottom surface of the block and has been downwardly projected auxiliary spacer block 26.
Further, 21 thickness of block is greater than 4cm, and the height of auxiliary spacer block 26 is greater than 3cm；The auxiliary spacer block
26 section is triangle, and auxiliary 26 lower end tip of spacer block is arc-shaped；The auxiliary spacer block 26 is integrally formed with block 21.By
This makes the effect for assisting spacer block 26 be not only in that the stress increased between block 21 and crossbeam 13, also resides in horizontal drawing spring 22
It is appropriate to release certain angle, horizontal drawing spring 22 is effectively promoted to the drop-down effect of block 21.
Preferably, the installation site of block 21 is the position on crossbeam 13 close to stringer 12.For theoretically, closer to
Effect is better, it should be noted that meeting under 21 horizontality of block has the item of overlapping in upright projection upper stopper 21 and carriage 11
Part.
In addition, the position for corresponding to block 21 in carriage 11, which should be arranged, thickens structure, to reduce carriage 11 and block 21
Damaged condition of the making contact process to 11 ontology of carriage.
