Description
Technical field
The present invention relates to the catch-releasing mechanism of a kind of M/C in case of emergency with the drg of release elevator lifting device, specifically, relating to one is used for multiple improvement is attached to catch-releasing mechanism so that the technology that catch-releasing mechanism can release the brake by the power that reduces.
Background technology
Elevator device has car and elevator lifting device, and described elevator lifting device is provided with traction sheave and drg.When car need vertical when mobile, by drg is discharged with electromagnetic mode, so that traction sheave is rotatable to the drg power supply.
When power supply was cut off, this drg can not be released, thereby car can not vertically move.Therefore, drg needs manual releasing for rescue operation, moves to nearest platform with the car of the position between the platform that will stop at adjacent layer.
In JP-A 2004-307181 and JP-A 2007-62900, proposed to be used for the drg of manual releasing elevator lifting device before the applicant of present patent application to implement the catch-releasing mechanism of emergency operation.
To above-mentioned catch-releasing mechanism be described referring to Figure 12 and 13.The elevator lifting device 2 that is provided with drg 3 is arranged in the upper part of elevator 1.Braking trigger bar 5 is supported on the wall of the elevator hall 4 on the top layer.Operation cable 6 has an end that is connected to the braking trigger bar and the other end that is connected to drg 3.
If drg 3 can not discharge owing to reasons such as power fails and car 7 can not vertically move, the rescue group operates braking trigger bar 5 manual releasing drgs 3.
Then, traction sheave 8 becomes rotatable, and car 7 can move up or down naturally by means of the weight difference between car 7 and the counterweight 9.Therefore, car 7 is movable to the podium level place of nearest layer.
As shown in figure 13, the drg 3 of elevator lifting device 2 comprises: two brake control levers 12 and 13 and displaceable member 14, described brake control lever 12 and 13 is supported for respectively can be by the horizontal pivot that extends laterally accordingly 10 and 11 longitudinal oscillations of shipping and reselling on another market, and described displaceable member 14 is pivotally connected to the upper part 12a and the 13a of brake control lever 12 and 13.
The quilt cover of operation cable 6 is enclosed within cable 6b among the outer tube 6a is connected to displaceable member 14 by unshowned attaching parts rear upper part 14.
When the rescue group operated braking trigger bar 5 pulling cable 6b, displaceable member 14 shifted forward along the direction of arrow A.Therefore, brake control lever 12 and 13 is rotated, to release the brake 3.
Because operation cable 6 extends to the elevator lifting device 2 the upper part that is arranged on elevator along the path with curve from the elevator hall of top layer, so outer tube 6a produces friction drag on the cable 6b that slides with respect to outer tube 6a.
Therefore, force the rescue group to apply sizable power, implement rescue with mobile car 7 to braking trigger bar 5.
And because elevator lifting device 2 is arranged in the upper part of elevator, the rescue group is difficult to from the situation of elevator hall's 4 visions ground identification drg 3 of top layer.
Summary of the invention
Therefore, the objective of the invention is to solve the variety of issue that exists in the conventional solution and a kind of improved catch-releasing mechanism is provided, described catch-releasing mechanism makes it possible to utilize low operating effort to discharge the drg that combines with elevator lifting device, and situation that can vision identification drg.
Being used in a first aspect of the present invention in case of emergency discharges to combine with elevator lifting device and have the catch-releasing mechanism that will be shifted with the drg of the displaceable member that releases the brake and comprises: handling device; And swing arm, described swing arm by said pivot be supported on the elevator lifting device, and have first swing part that is connected to handling device and second swing part that is connected to displaceable member; Wherein, the distance between the pivotal axis and first swing part is greater than the distance between the pivotal axis and second swing part.
In the catch-releasing mechanism in a first aspect of the present invention, swing arm has leverage, and this leverage utilizes rod principle that the displaceable member of drg is shifted, to release the brake.
For example, if the distance between the pivotal axis and first swing part is two double-lengths of the distance between the pivotal axis and second swing part, the displaceable member of drg can be shifted by release the brake half of required power of existing catch-releasing mechanism.
Handling device can comprise braking trigger bar in the elevator hall that is arranged on top layer and the operation cable of being operated by the braking trigger bar, maybe can comprise being attached to elevator lifting device and passing through battery powered electric actuator.
Electric actuator can be controlled by control setup, and described control setup can be by the operating personal operation in the monitoring and control centre work of the operation that is used for the telemonitoring elevator device.
But the pivotal axis level of swinging in the cross rest bar, vertically or with respect to the horizontal direction diagonally extending.
When the pivotal axis horizontal-extending of swinging in the cross rest bar and swing arm are supported for when elevator lifting device projects upwards, the wobbling action of the upper end of swing arm and working of brakes situation can be at an easy rate from elevator hall's identification of top layer.
The mark of sign reflective paint or be similar to the light reflective devices of the device that is attached to automobile or bicycle rear portion on rotation end at swing arm, the for example light reflector or the light zone of reflections, when being attached to the rotation end of swing arm, the situation of swing arm can be at an easy rate by with irradiation unit for example the rotation end of flash light irradiation swing arm from elevator hall's vision identification of top layer.
By swing arm, can prevent because operating personal is being used for checking that the working process of elevator lifting device and catch-releasing mechanism is not intended to touch swing arm and makes the drg accident discharge owing to the dust accumulation on the catch-releasing mechanism causes the catch-releasing mechanism fault with the cover cap cover cap.
When cover cap is made by transparent material, the situation of swing arm can be easily from the elevator hall of top layer by the cover cap identification.
Catch-releasing mechanism can comprise the extrusion equipment that is used to push swing arm, and swing arm is remained on the predetermined start position, in described predetermined start position, swing arm does not make the displaceable member displacement of drg.
Therefore, the outer tube that can prevent drg reliably because the cable of operation cable is pulled to release the brake is applied to friction drag on the cable and limits it and turn back to its initial position and unexpectedly keep discharging.
Catch-releasing mechanism of the present invention makes that being used to discharge the required braking release force of drg that combines with elevator lifting device reduces, and is convenient to vision identification working of brakes situation.
