Abstract
The utility model relates to a safety device of an elevator, comprising a safety airbag which is arranged at the bottom part of an elevator cabin. An explosive device or a compressed gas cylinder device which can lead the safety airbag to expand rapidly is arranged in the safety airbag; and the elevator cabin is provided with a detection trigger device which can open a valve of the explosive device or the compressed gas cylinder device. The utility model is mainly applied on the elevator, and aims at providing a safety device with simple structure, practicability and safety.
Description
[technical field]
The present invention relates to a kind of safety device, in particular a kind of safety device that is applied to elevator.
[background technology]
The safety device of elevator generally all is the structure more complicated at present, and employed cost is than higher, and the expense of maintenance is than higher.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, and the safety device of a kind of safety simple in structure, practical, elevator that cost is lower is provided.
In order to solve the technical matters of above-mentioned existence, the present invention adopts following technical proposal:
As above a kind of safety device of elevator, it is characterized in that including the safety air bag that is located at the lift car bottom, in safety air bag, be provided with and make its exploder or compressed gas cylinder device of expanding rapidly, on lift car, be provided with a detection flip flop equipment that can make the valve open of exploder blast or compressed gas cylinder device.
The safety device of aforesaid a kind of elevator, it is characterized in that described detection flip flop equipment includes one with the upper and lower rotor wheel that can rotate when mobile of lift car with detect the electronic speed probe of rotor wheel rotating speed, the triggering wire joint of described electronic speed probe is in exploder or compressed gas cylinder device.
The safety device of aforesaid a kind of elevator is characterized in that described safety air bag is two.
The safety device of aforesaid a kind of elevator is characterized in that also being provided with the guiding steel rope in the lift car both sides, is respectively equipped with the sliding guide shoe wheel that can steadily move on the guiding steel rope in the lift car both sides, and described rotor wheel is adjacent on the guiding steel rope.
The present invention compared with prior art has following advantage:
Because the present invention adopts the safety air bag that is arranged on the lift car bottom, be provided with exploder or compressed gas cylinder device in the safety air bag, on safety air bag, be provided with one and detect flip flop equipment, when elevator breaks down when falling downwards, detect flip flop equipment and will detect fault and trigger the valve open that exploder explodes or makes the compressed gas cylinder device, make it produce a large amount of gases, make the safety air bag rapid expanding, when elevator drops to the ground, reduced the injures and deaths probability widely like this; Have this kind safety device simple and reliable again, cost is not high yet.
[description of drawings]
Fig. 1 is that the present invention is installed in one of block diagram on the lift car;
Fig. 2 be the present invention be installed in block diagram on the lift car two;
Fig. 3 is that the present invention installs the schematic perspective view on the elevator;
Fig. 4 is the A portion enlarged drawing of Fig. 1.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
A kind of safety device of elevator includes and is located at lift car 1 bottom and is provided with safety air bag 2, is provided with for 2 li at safety air bag and can makes its exploder that expands rapidly, is provided with a detection flip flop equipment 4 that can make the exploder blast on lift car 1.
Described detection flip flop equipment 4 includes one with upper and lower rotor wheel 5 that can rotate when mobile of lift car 1 and the electronic speed probe that detects rotor wheel 5 rotating speeds, lift car 1 upper and lower mobile speed just can embody at the speed of rotor wheel 5 velocities of rotation like this, the triggering wire joint of described electronic speed probe is to 2 li of safety air bags, described triggering wire joint is on exploder and can make its blast, and described exploder mainly is an explosive.
Described exploder also can replace with the compressed gas cylinder device, pressure gas is housed in the described compressed gas cylinder device and is provided with valve, described triggering wire joint is to the compressed gas cylinder device, in case of emergency, detect flip flop equipment 4 and can make valve open by triggering line, then the gas in the compressed gas cylinder device will discharge at once, and safety air bag 2 is expanded rapidly.
Be provided with guiding steel rope 6 in lift car 1 both sides, be respectively equipped with the sliding guide shoe wheel 7 that can on guiding steel rope 6, steadily move in lift car 1 both sides, described guiding steel rope 6 passes sliding guide shoe wheel 7, so lift car 1 is under the drawing of drag device 2 and down can be upper and lower reposefully mobile the spacing of sliding guide shoe wheel 7, the rotor wheel 5 of described detection flip flop equipment 4 is adjacent on guiding steel rope 6, so lift car 1 upper and lower mobile in, rotor wheel 5 also can and then rotate under the effect of guiding steel rope 6.Described electronic speed probe just can be measured the rotating speed of rotor wheel 5, so the speed of rotor wheel 5 rotating speeds all reflects on electronic speed probe, when in case drag device 2 is held the hoist ropes disconnection of lift car 1, lift car 1 directly can fall downwards, at this moment unexpected change can appear in the speed of lift car 1, it directly is reflected on rotor wheel 5 rotating speeds, electronic speed probe can directly detect abnormal condition, can send signal, make the exploder blast of 2 li of safety air bags or make valve open, then the gas in the compressed gas cylinder device will discharge at once, produce a large amount of gases, safety air bag 2 is expanded rapidly, in the time of like this on lift car 1 ground, safety air bag 2 can cushion the speed of lift car 1 greatly, greatly reduces the possibility of personal casualty.
Described safety air bag 2 is two, so can guarantee safety better.
