Embodiment
The present invention is described in detail with reference to specific embodiment and Figure of description.
As shown in Figure 1 to 4, elevator power safety arrangement for disabled provided by the invention, including screw rod, bearing screwed cap
10 and jam nut 20, the connecting plate 30 for connecting lift is fixed with bearing screwed cap 10.
Jam nut 20 and bearing screwed cap 10 are arranged on screw rod, jam nut 20 be located at the top of bearing screwed cap 10 and
Therebetween it is provided with gap, is convexly equipped with caging bolt towards the direction of connecting plate 30 on jam nut 20, connecting plate 30 is provided with can
The spacing hole 31 slided for caging bolt 21, connecting plate 30 are provided with safety switch, safety switch close to one end of jam nut 20
The limit switch triggered by way of pushing is may be configured as, is easy to the startup of safety switch, such as Roller fork type limit switch
Deng.
The application method of the present invention is as follows：
During normal use, passenger stands on lift, and bearing screwed cap 10 drives elevator motion by connecting plate 30, now
Jam nut 20 and the synchronizing moving of bearing screwed cap 10, caging bolt 21 are arranged on one end of spacing hole 31.
After bearing screwed cap 10 fails, lift drives connecting plate 30 and carrying in the presence of itself and passenger's gravity
Nut 10 is drastically glided, and caging bolt 21, which slides in spacing hole 31 and is finally limited hole 31, to be stopped, can play support lifting
The effect of machine, and jam nut 20 is contacted and triggered with safety switch, safety switch feeds back signal to control system, control
System control brake starts, and screw rod is stopped operating, and lift stops declining, and realizes deceleration of electrons, protects the safety of passenger.
If safety switch fails, similarly caging bolt 21 is kept out slides and is finally limited hole 31 in spacing hole 31
Stop, while playing support lift effect, elevator motion can be driven, play a part of carrying, referred to when lift reaches
Behind fixed position, staff is repaired again, further ensures that the safety of passenger.
And by the kind of drive of bearing screwed cap 10 and screw rod, when resident family building powers off suddenly, screw rod will stop operating,
And then bearing screwed cap 10 is rested on the position, prevent the situation that lift drastically declines after powering off and occur, ensure passenger
The security used.
Safety switch includes the installing plate 41 being arranged on connecting plate 30 and the box body 40 for being arranged on the bottom surface of installing plate 41, box
Touching switch is provided with body 40, the side of box body 40 towards connecting plate 30 is equipped with switch trigger gear 42, switch trigger gear
42 can be shell fragment, connecting rod or lever, simple in construction, reduce design difficulty.When bearing screwed cap 10 fails, jam nut 20, which slides, to be squeezed
Compress switch one end of trigger device 42, and the other end of switch trigger gear 42 is triggered touching switch, and then starts safety open
Close, safety switch feeds back signal to control system, and control system control brake starts, and screw rod is stopped operating, it is ensured that lifting
Machine it is safe to use.
One end of installing plate 41 is provided with adjusting rod, the adjustment hole for being available for adjusting rod to slide is provided with connecting plate 30, by changing
Become position of the adjusting rod in adjustment hole, adjust the distance between safety switch and jam nut 20, can accurately adjust safety
The position of switch, to ensure that jam nut 20 will not trigger safety switch during following bearing screwed cap 10 to move, and work as
After bearing screwed cap 10 fails, the enough very first time triggering safety switches of the and can of jam nut 20, start brake, make screw rod stop turning
It is dynamic, it is ensured that the safety of passenger.
As shown in figure 4, switch trigger gear 42 and 40 setting at an acute angle of box body, are easy to its stress to trigger safety switch, if
If switch trigger gear 42 directly contacts with jam nut 20, due to switch trigger gear 42 end face in the form of sheets, therefore can increase
Add frictional force between the two, accelerate device damage, therefore one projection 43 is set in the free end of switch trigger gear 42, it is convex
Block 43 can be set to cylindric, and its outer peripheral face contacts with jam nut 20, reduces frictional force, makes slip more smooth.
As depicted in figs. 1 and 2, connecting plate 30 is arranged with two mounting grooves 32, each mounting groove along its length direction
Be equipped with two spacing holes 31 in 32, the design of multiple spacing holes 31 and caging bolt 21, reduce each caging bolt 21 by
Power, while greater weight lift can be born, and be symmetrical arranged, make each uniform force of caging bolt 21, enter one
Step improves the security used.
The top of caging bolt 21 is provided with block 22, prevents caging bolt 21 from departing from spacing hole 31, block 22 is in mounting groove
Slided in 32, the fluency that increase caging bolt 21 slides in spacing hole 31.
The present invention, jam nut is provided with above bearing screwed cap, when bearing screwed cap fails by much time using
Afterwards, lift drives connecting plate and bearing screwed cap drastically to glide in the presence of self gravitation, and now caging bolt is spacing
Slided in hole and be finally limited hole stop, prevent connecting plate from continuing slide downward, while jam nut contacts with safety switch
And triggered, safety switch feeds back signal to control system, and control system order brake disconnects, and the device is stopped fortune
It is dynamic, prevent the generation for causing security incident because of drastically declining for lift, it is ensured that the security that lift uses.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn that the knot made under the enlightenment of the present invention
Structure changes, and the technical schemes that are same or similar to the present invention, each falls within protection scope of the present invention.
