Detailed description of the invention
As Fig. 1, the utility model steel rope fault protection mechanism is arranged between the movable stand 1 of passageway lift and framework 2.Described framework 2 is general frames of passageway lift, and arrange along staircase steps, motor draws described movable stand 1 by steel rope 7 and moves in described framework, namely moves along described staircase steps rise and fall direction.In order to prevent steel rope 7 from occurring the fault such as fracture when drawing, then steel rope fault protection mechanism is set and there is the passageway lift safety system of this protection mechanism.
Described steel rope fault protection mechanism comprises safety detents, front jocket wheel bearing pin 8, elastomeric element, fracture of wire safety guard 6.Described safety detents is connected with described movable stand 1 by described front jocket wheel bearing pin 8; described elastomeric element is arranged on the described front jocket wheel bearing pin 8 between described safety detents and described movable stand 1; described elastomeric element makes safety detents rotate around front jocket wheel bearing pin 8; for described safety detents snap catch steel rope protection process provides energy, also for steel rope 7 tension provides enough tensile forces.Described elastomeric element can be safety detents torsion spring 5.
Described safety detents is one-body molded, has brake portion 31, connecting portion 32, stop part 33.Described connecting portion 32 is in order to be connected with described steel rope 7.Described brake portion 31 is an end of the described safety detents near described framework 2, described brake portion 31 acts on the fracture of wire safety guard 6 arranged on the frame 2, when described fracture of wire safety guard 6 is for being made up of multiple zig-zag projection, described multiple zig-zag projection at equal intervals continuous arrangement is arranged on described framework 2.Effectively coordinate with described fracture of wire safety guard 6 to make described brake portion 31, as as described in brake portion 31 firmly insert adjacent as described between zig-zag projection, or described brake portion 31 is firmly engaged with described zig-zag projection, as preferably, described brake portion 31 have with described zig-zag projection face the contact level offseted, the contact surface offseted with the inclined-plane of described zig-zag projection, the contact bottom surface that contacts with the septal surface of adjacent two described zig-zag projections directly.When wire cable rupture, this safety detents gravitate falls, add the effect of elastomeric element, fall more quickly and effectively, now described brake portion 31 and the effect of described fracture of wire safety guard, especially described brake portion 31 inserts the position between adjacent two described zig-zag projections, when the contact level in described brake portion 31 and adjacent previous described facing directly of zig-zag projection offset, contact surface is large, effectively stops described brake portion 31 to travel forward because of inertia while providing brake weight; The contact surface in described brake portion 31 and the inclined-plane of an adjacent rear described zig-zag projection offset, and coordinate facing directly of previous described zig-zag projection to fix with described brake portion 31.More stable in order to brake, need for drag process provides the buffering course of a drag, then the length arranging described contact bottom surface is less than the length of the septal surface of adjacent two described zig-zag projections.
Described stop part 33 is an end of the described safety detents near described movable stand.In order to limit the position of described safety detents when steel rope is strained, described movable stand 1 arranging extension 11, when described extension 11 offsets with described stop part 33, making described safety detents be fixed on this state.Spacing in order to coordinate, described in decision design, stop part 33 has right-angle notch 331, make described extension 11 the vertical of described stop part 33 breach 331 and horizontal direction effectively spacing, prevent safety detents from departing from fracture of wire safety guard 6 position, cannot useful effect.
Described safety detents also has fixed part 34, when described elastomeric element is safety detents torsion spring 5, described safety detents torsion spring 5 is wrapped on described front jocket wheel bearing pin 8, and described safety detents torsion spring 5 one end is fixed on described movable stand 1, and the other end is fixed on described fixed part.
In order to be connected the passageway lift protection system realizing intelligent brake with described apparatus for controlling elevator, described steel rope fault protection mechanism also comprises micro-switch 4.Described micro-switch 4 is arranged on described extension 11.Described stop part 33 is formed with diff-H when matching with described extension 11, and the position that described stop part 33 exceeds described extension 11 is connected with described micro-switch 4.When wire cable rupture, described safety detents falls, described stop part 33 no longer offsets with described extension 11, described stop part 33 triggers the micro-switch 4 be attached thereto simultaneously, the apparatus for controlling elevator be now connected with micro-switch 4 receives wire cable rupture signal, and apparatus for controlling elevator disable motor power supply also sends alarm signal; Described brake portion 31 acts on fracture of wire safety guard 6 simultaneously, realizes mechanical brake and stops movable stand 1 to move.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
