Embodiment
Such as Fig. 1, steel rope fault protection mechanism of the present invention is arranged between the movable stand 1 of passageway lift and framework 2.It is described
Framework 2 is the general frame of passageway lift, is set along staircase steps, and motor draws the movable stand 1 described by steel wire rope 7
Move, i.e., moved along the staircase steps rise and fall direction in framework.In order to prevent steel wire rope 7 from occurring being broken in traction
Failure, then set steel rope fault protection mechanism and the passageway lift security system with the protection mechanism.
The steel rope fault protection mechanism includes safety detents, front jocket wheel bearing pin 8, elastomeric element, fracture of wire guard plate 6.
The safety detents are connected by the front jocket wheel bearing pin 8 with the movable stand 1, and the elastomeric element is arranged on the safe spine
On the front jocket wheel bearing pin 8 between pawl and the movable stand 1, the elastomeric element makes safety detents be revolved around front jocket wheel bearing pin 8
Turn, energy is provided for safety detents fast braking steel wire rope protection process, also tensed for steel wire rope 7 and tensioning enough is provided
Power.The elastomeric element can be safety detents torsion spring 5.
The safety detents are integrally formed, with brake portion 31, connecting portion 32, stop part 33.The connecting portion 32 is used to
It is connected with the steel wire rope 7.The brake portion 31 is the one end of the safety detents close to the framework 2, the brake
Portion 31 is with setting fracture of wire guard plate 6 on the frame 2 to act on, when the fracture of wire guard plate 6 is to be made up of multiple zigzag projections
When, the raised continuous arrangement at equal intervals of the multiple zigzag is arranged on the framework 2.In order that the brake portion 31 with it is described
Fracture of wire guard plate 6 effectively coordinates, and brake portion 31 is firmly inserted between the adjacent zigzag projection as described, or the brake portion 31
Consolidate and be engaged with zigzag projection, offseted preferably, the brake portion 31 has with raised the facing directly of the zigzag
Contact plane and the contact surface that offsets of the raised inclined-plane of the zigzag between the two neighboring zigzag projection
The contact bottom surface contacted every face.When wire cable rupture, the safety detents are fallen by Action of Gravity Field, add the work of elastomeric element
With more quickly and effectively, now the brake portion 31 is acted on the fracture of wire guard plate, and especially described brake portion 31 is inserted for whereabouts
Position between the two neighboring zigzag is raised, when contact plane and the adjacent previous zigzag in the brake portion 31
Raised facing directly is offseted, and contact surface is big, and the brake portion 31 is effectively prevented because inertia travels forward while brake weight is provided；
The contact surface in the brake portion 31 offsets with the adjacent raised inclined-plane of the latter zigzag, coordinates the previous sawtooth
Raised the facing directly of shape is fixed with the brake portion 31.In order to brake more stable, it is necessary to provide a brake system for skidding process
Dynamic buffering course, then set the length of the contact bottom surface to be less than the length of the raised septal surface of the two neighboring zigzag
Degree.
The stop part 33 is the one end of the safety detents close to the movable stand.Tensed to limit steel wire rope
The position of Shi Suoshu safety detents, sets extension 11, when the extension 11 and the stop part 33 on the movable stand 1
When offseting so that the safety detents fixation is in this state.Spacing in order to coordinate, stop part 33 described in decision design has right angle
Breach 331 so that the extension 11 prevents peace in the vertically and horizontally effectively spacing of the breach 331 of stop part 33
Full ratchet deviates the position of fracture of wire guard plate 6, it is impossible to useful effect.
The safety detents also have fixed part 34, when the elastomeric element is safety detents torsion spring 5, the safe spine
Pawl torsion spring 5 is wrapped on the front jocket wheel bearing pin 8, and described one end of safety detents torsion spring 5 is fixed on the movable stand 1, another
End is fixed on the fixed part.
Realize that the passageway lift of intelligent brake protects system to be connected with the apparatus for controlling elevator, the steel wire rope breaks
Silk protection mechanism also includes microswitch 4.The microswitch 4 is arranged on the extension 11.The stop part 33
Be formed with difference in height when being engaged with the extension 11, the stop part 33 be higher by the position of the extension 11 with it is described micro-
Dynamic switch 4 is connected.When wire cable rupture, the safety detents fall, the stop part 33 no longer with the phase of extension 11
Support, while the stop part 33 triggers the microswitch 4 being attached thereto, the elevator controlling system being now connected with microswitch 4
System receives wire cable rupture signal, and apparatus for controlling elevator closes motor power and signal an alert；While the brake portion
31 act on fracture of wire guard plate 6, realize that mechanical brake stops movable stand 1 and moved.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the design of the present invention
It is defined with scope.On the premise of design concept of the present invention is not departed from, technical side of this area ordinary person to the present invention
The all variations and modifications that case is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
Through all recording in detail in the claims.
