Being connected by described hex bolts between ferrum, short striking plate and elongated hole angle bar, the bottom of described hex bolts is provided with described nut,
The top of described nut is provided with described spring washer, and the top of described spring washer is provided with described plain cushion.
As a kind of optimal technical scheme of the present utility model, described long angle bar, short striking plate and the contact surface of elongated hole angle bar
Length identical.
As a kind of optimal technical scheme of the present utility model, the side of the bottom of described short striking plate is provided with groove.
As a kind of optimal technical scheme of the present utility model, the sectional view of described elongated hole angle bar is L-type, and described elongated hole
The side of angle bar is provided with groove.
As a kind of optimal technical scheme of the present utility model, the bending angle at described spacing long striking plate two ends is 30
Degree.
Compared with prior art, the beneficial effects of the utility model: may insure that the upper and lower limit bit switch of elevator, upper,
Limit inferior switch and speed reducing switch, in predetermined stroke, enable the limit switch of correspondence to be triggered timely, prevent from hanging
Exceeding during cage upstream or downstream needs off-position to put, and considerably increases the job safety coefficient of workmen.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, with this practicality
Novel embodiment is used for explaining this utility model together, is not intended that restriction of the present utility model.
In the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model；
Label in figure: 1, long angle bar；2, spacing long striking plate；3, short striking plate；4, elongated hole angle bar；5, hex bolts；6, nut；

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment: as shown in Figure 1-2, this utility model provides a kind of building hoist stroke limit to touch ferrum, including long
Angle bar 1, spacing long striking plate 2, short striking plate 3, elongated hole angle bar 4, hex bolts 5, nut 6, spring washer 7 and plain cushion 8, the top of long angle bar 1
End is provided with spacing long striking plate 2, and the bottom of long angle bar 1 is provided with short striking plate 3, and the side of long angle bar 1 is provided with elongated hole angle bar 4,
Being connected by hex bolts 5 between long angle bar 1, short striking plate 3 and elongated hole angle bar 4, the bottom of hex bolts 5 is provided with nut 6, spiral shell
The top of female 6 is provided with spring washer 7, and the top of spring washer 7 is provided with plain cushion 8.
Long angle bar 1, short striking plate 3 are identical with the length of the contact surface of elongated hole angle bar 4；It is easy to long angle bar 1, short striking plate 3 and
Fixing of elongated hole angle bar 4.
The side of the bottom of short striking plate 3 is provided with groove；It is easy to the installation of short striking plate 3.
The sectional view of elongated hole angle bar 4 is L-type, and the side of elongated hole angle bar 4 is provided with groove；It is easy to be connected with long angle bar 1
Fixing.
The bending angle at spacing long striking plate 2 two ends is 30 degree；It is easy to the installation of spacing long striking plate 2.
Concrete when the up predetermined travel position of the up fast arrival of cage, upper deceleration is touched ferrum and is triggered speed reducing switch, makes
The deceleration that cage is suitable, it is to avoid operator fail in time elevator so that height operation approaches the high-low limit position on guide rail bracket
Slow down, make the installation of elevator inertia or rush to summit and shine into contingency；When the up arrival of cage is up need off-position to put time, upper limit
Touch ferrum and trigger up limit switch, cutting-off controlling circuit, make actuating device out of service, prevent cage from rushing to summit and have an accident；When
When occurring up limit switch ineffective, when cage runs more than limit switch surpassed distance, upper limit by row touches ferrum and triggers cage
Limit superior switchs, and whole elevator main power cuts off, and actuating device quits work, it is ensured that elevator duty safety.When under cage
Row near descending need off-position to put time, lower deceleration is touched ferrum and is triggered the speed reducing switch pipe on cage, makes the deceleration that cage is suitable, prevent from hanging
There is born potential safety hazard in cage hypervelocity；When the descending arrival of cage is descending need off-position to put time, lower limit is touched ferrum and is triggered descending spacing open
Close, cutting-off controlling circuit, make actuating device out of service, prevent the steel wire rope looseness wadding that maloperation is drawn on actuating device disorderly.Under
Limit switch in normal operation, before cage encounters buffer；When running into, down stroke limit switch control system is malfunctioning,
After one section of surpassed distance distance, the down stroke limit is touched ferrum and is triggered limit switch, and whole elevator main power cuts off, and hoist engine stops work
Make, it is ensured that steel wire rope marshalling all the time, not in relaxed state.
This utility model may insure that the upper and lower limit bit switch of elevator, and Upper-lower Limit switch and speed reducing switch, in advance
In fixed stroke, enable the limit switch of correspondence to be triggered timely, prevent from exceeding during cage upstream or downstream needing off-position
Put, considerably increase the job safety coefficient of workmen.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this reality
With novel, although this utility model being described in detail with reference to previous embodiment, those skilled in the art is come
Saying, the technical scheme described in foregoing embodiments still can be modified by it, or enters wherein portion of techniques feature
Row equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should
Within being included in protection domain of the present utility model.
