Below by way of the drawings and specific embodiments, the present invention is described further:
Detailed description of the invention
As shown in Figures 1 to 4, the mechanical brake-releasing gear of a kind of machine-roomless lift drg of the present invention, comprises the operating mechanism 1 that to declutch outside two drgs 4, well, double-arm brake declutches connecting rod mechanism 2 and is connected to the tricing line 3 that declutches that to declutch outside well operating mechanism 1 and double-arm brake declutch between connecting rod mechanism 2.Concrete structure of the present invention is as follows:
The operating mechanism 1 that declutches outside described well is arranged on outside hoistway, and it comprises operating handle 11, pedestal 12 and is arranged on the semi-disc be connected on pedestal 12 and with the tricing line 3 that declutches locks leverage 13; Described semi-disc locking leverage 13 is provided with the hold-down arm 131 for being flexibly connected with operating handle 11, the object of such design is, when operating at ordinary times, can operating handle 11 be received to box for spares, taking up room of the operating mechanism 1 that declutches outside minimizing well.Described operating handle 11 is for operating tension or loosening the tricing line 3 that declutches.
Described double-arm brake declutches on elevator main that connecting rod mechanism 2 is arranged in elevator hoistways, it is arranged with first arm 21 and second that declutches and declutches arm 22, drg 4 is all installed at first the declutch middle part of arm 22 of arm 21 and second of declutching, particularly, described first arm 21 and second arm 22 that declutches that declutches is connected with drg 4 by telescopic regulating mechanism 5, the distance that this telescopic regulating mechanism stretches out for adjusting drg 4.Described first arm 21 and second arm 22 that declutches that declutches is hinged on elevator main in one end respectively, the other end is hinged on a linkage rod slide block mechanism 23 be connected with the tricing line 3 that declutches, to arrange the first bearing 24 and first arm 21 that declutches hinged for elevator main particularly, and it is hinged to arrange the second bearing 25 and second arm 22 that declutches.The support that the arm configuration that declutches like this exists two hinge-points is stressed, when making brake stressed evenly and firm, and the stressed support that the lever that declutches that prior art Chinese patent 200820088412 adopts only has one end one-sided, and drg is mounted in the free end of the lever that declutches, therefore brake stressed instability, easily occur rocking and losing efficacy.
Further, described linkage rod slide block mechanism 23 comprises: base 231, vertical mount pad 232, transverse slider 233, swing connecting bar 234, vertical slide block 235, first rocker-arm link 236 and the second rocker-arm link 237, and concrete connection structure is as follows:
Described base 231 is arranged on elevator main, and it is provided with horizontal concrete chute 2311, and as preferably, described horizontal concrete chute 2311 is the horizontal groove of falling T.
Described vertical mount pad 232 is arranged on base 231, and the corresponding horizontal concrete chute 2311 in this vertical mount pad bottom is provided with and laterally dodges chamber 2322, and top is provided with and laterally dodges the through vertical chute 2321 in chamber 2322.
Described transverse slider 233 is arranged on horizontal concrete chute 2311 li and is connected with the tricing line 3 that declutches.
Described swing connecting bar 234 be arranged on laterally dodge 2322 li, chamber and lower end and transverse slider 233 hinged.Under braking mode, namely under the state that the tricing line that declutches 3 is not pulled, as shown in Figure 5, the angle α between swing connecting bar 234 and transverse slider 233 is sharp angle to the connection structure of transverse slider 233 and swing connecting bar 234, and the opening direction of angle α points to the one end connecting the tricing line 3 that declutches.When the tricing line 3 that declutches pulls transverse slider 233 to move at horizontal concrete chute 2311, make the angle α of swing connecting bar 234 and transverse slider 233 by little increase (as shown in Figure 6), namely swing connecting bar 234 is raised upwards, and promotes vertical slide block 235 and rises.
Described vertical slide block 235, it is arranged on vertical chute 2321 li and lower end and swing connecting bar 234 upper end thereof.
Described first rocker-arm link 236 one end and vertical slide block 235 hinged, the other end and first arm 21 that declutches is hinged.
Described second rocker-arm link 237 one end and vertical slide block 235 hinged, the other end and second arm 22 that declutches is hinged.
Further, automatically can recover braking after making to declutch, between described horizontal concrete chute 2311 and transverse slider 233, be provided with elastic recovery structure; Described elastic recovery structure is a stage clip 6, and this stage clip 6 is located between horizontal concrete chute 2311 antetheca and transverse slider 233 front end.It is pointed out that and describedly refer to that to chute 2311 antetheca, transverse slider 233 front end both install the one end of the tricing line 3 that declutches.
The described tricing line 3 that declutches is for Bowden cable.
Below by way of embody rule principle, the present invention is described further:
When needs execution drg machinery declutches task, operator is hoistway outer (or crying outside the Room), the handle 11 that declutches is taken out from box for spares, by the hold-down arm 131 of the operating mechanism 1 that declutches outside one end fill in well of the handle 11 that declutches, the hand-held other end, certain power is applied according to the arrow points direction of declutching outside Fig. 1 well on operating mechanism 1, conducted by semi-disc locking leverage 13, the tricing line that declutches 3 is subject to corresponding pulling force and produces displacement, thus pull transverse slider 233 to slide at the horizontal concrete chute 2311 of base 231, make the angle α of swing connecting bar 234 and transverse slider 233 by little increase, promote vertical slide block 235 upward sliding in vertical chute 2321, drive the first rocker-arm link 236 and the second rocker-arm link 237 upward movement, first arm 21 and second that declutches is made to declutch arm 22 around the first bearing 24, the jointed shaft of the second bearing 25 upwards swings, thus make to be arranged on first drg 4 that arm 21 and second declutches in the middle part of arm 22 that declutches and move up, realize drg machinery to declutch.
While stating mechanism action in realization, act on the operating effort declutched on handle 11, the transverse slider 233 that double-arm brake declutches on connecting rod mechanism 2 is delivered to by the tricing line 3 that declutches, again by swing connecting bar 234, vertical slide block 235, power one-level level is amplified by the first rocker-arm link 236 and the second rocker-arm link 237, the first arm 21 and second arm 22 that declutches that declutches, and finally reaches to realize drg and to declutch required application force.
When not needing manually to declutch, only the handle 11 that declutches need be resetted, the tricing line that declutches 3 is in relaxation state, transverse slider 233 is under the thrust of stage clip 6, no longer pushing tow swing connecting bar 234, swing connecting bar 234 transfers comparatively heeling condition to by close to vertical state under the thrust of vertical slide block 235, vertical slide block 235 vertically chute 2321 slide downward under the effect of the first rocker-arm link 236 and the second rocker-arm link 237, make first arm 21 and second that declutches declutch arm 22 to lower swing, promote the first rocker-arm link 236 and the second rocker-arm link 237 moves down.Due in the tricing line 3 that now declutches without pulling force, drg 4 just can be braked the rope sheave of elevator main.
