Wheel movable base 3 moves on the supporting rod of support component, and under normal condition, switch movable contact point 52 and switch stationary contact point 6 do not connect
It touches, safety arrestment circuit is not activated, elevator normal operation；When generation speed limiter wire rope is stretched over setting length or breaks
After splitting, the switch movable contact point 52 is in contact with switch stationary contact point 6, and safety arrestment circuit is triggered at this time, and elevator is out of service.
The safety arrestment circuit is elevator general circuit, is repeated no more herein.
Specifically, the support component includes supporting rod 21, gasket 22, locking nut 23, speed limit spring 24.The tensioner
It takes turns 3 both sides of movable base and is equipped with through-hole, the supporting rod 21 of two groups of support components is respectively allowed for pass through.The supporting rod 21 runs through institute
It is fixedly connected with pedestal 1 after stating expansion tightening wheel movable base 3.The speed limit spring 24 is sheathed on the supporting rod 21, and tensioner in
Between the gasket 22 and 3 upper surface of expansion tightening wheel movable base, the locking nut 23 is set to 22 top of the gasket, uses
In compressing the gasket 22.In the way of the present invention replaces original counterweight tensioner in the way of the elastic tensioning of spring, reduce pair
The space hold of hoistway, and installation maintenance is flexibly convenient.In addition, 21 upper end of supporting rod of two groups of support components is fixedly connected on together
On the one hand the both sides of one substrate 7 can avoid locking nut 23 and loosen and cause the no longer tensioner of speed limit spring 24 in the gasket 22
Between 3 upper surface of expansion tightening wheel movable base, swelling device is caused to trigger safety arrestment when normal elevator is run in this way
Circuit so that elevator is stopped transport suddenly；On the other hand two groups of support elements are forced through same substrate and transmit, two groups of support element stress phases
To uniform.
The pedestal 1 includes base station 11 and supporting rack.Support frame as described above includes upper backup pad 121, lower supporting plate 122 and connects
The connecting plate 123 of support plate 121 and lower supporting plate 122 is connected, the lower supporting plate 122 is set to 11 upper surface of the base station, institute
It states after supporting rod 21 sequentially passes through expansion tightening wheel movable base 3, upper backup pad 121 and is fixed on lower supporting plate 122.In order to avoid rising
Bearing up pulley 4 is interfered with 1 base station of pedestal, and support frame as described above is set as the U-shaped shape of accumbency, so that the two distance is pulled open.It is described to open
The upper surface that stationary contact 6 is set to the upper backup pad 121 is closed, the upper backup pad 121, which has, to be extended to base center direction
Extension board, the extension board are equipped with switch stationary contact point 6；And the connecting plate 51 of the safety switch assembly is in the axial direction to downward
It stretches, switch movable contact point 52,6 cloth opposed in the axial direction of the switch movable contact point 52 and switch stationary contact point is arranged in elongated end
It sets.The top of the upper backup pad 121 also sets up stop nut 8, and length is moved down to limit expansion tightening wheel movable base 3.In order to
The expansion tightening wheel movable base when restricting overrelaxation or being broken is avoided to move down and damage pedestal by pressure, the upper backup pad 121 and institute
It states and is arranged with tensioner spring 9 on the supporting rod 21 between lower supporting plate 122.In addition, the upper backup pad and the lower supporting plate
Between spacing distance be 5-8cm, the tensioner between relatively narrow upper backup pad 121 and lower supporting plate 122 of tensioner spring 9, into one
Step alleviates the impulse force that expansion tightening wheel movable base moves down.Further, the tensioner spring 9 is held out against respectively in the upper backup pad 12
The position of lower surface and the upper surface of the lower supporting plate 122 is equipped with Rubber shock-absorbing pad.
Further for avoiding expansion tightening wheel 4 and the base station 11 of pedestal from interfering, the base station is with axially penetrating through
