Description
Technical field
The utility model relates to a kind of elevator safety function unit, relates in particular to a kind of control setup for elevator safety gear.
Background technology
The welding connecting rod mostly existing most of link mechanism for elevator safety tongs is to be installed on the upper beam channel-section steel adds large-scale spring and release gear design, and quality is heavy, complex structure, and cost is high.
The utility model content
For above-mentioned prior art, the utility model provides a kind of control setup for elevator safety gear, has simplified link mechanism for elevator safety tongs, has reduced cost, has saved the energy, and is convenient to installation and maintenance.
In order to solve the problems of the technologies described above, the utility model is used for the technical scheme that the control setup of elevator safety gear is achieved: comprise velocity limiter wheel, speed limiter wire rope, expansion tightening wheel, the first safety tongs voussoir, the second safety tongs voussoir and safety tongs shift mechanism, described safety tongs shift mechanism comprises a rotating shaft, the first safety tongs voussoir pull bar, the second safety tongs voussoir pull bar and a Compress Spring; The first safety tongs voussoir pull bar and the second safety tongs voussoir pull bar weld with the two ends of described rotating shaft respectively, also be welded with a driving lever in the described rotating shaft, the other end of described driving lever contacts with the contact of elevator limit switch, the first safe abaculus pull bar is provided with a fulcrum, and this fulcrum and described speed limiter wire rope are hinged; One end of described Compress Spring is fixed on the lift car, contacts at fulcrum with bar section between the rotating shaft weld nugget on the other end of described Compress Spring and the first safe abaculus pull bar.
The utility model is used for the control setup of elevator safety gear, and wherein, the neutral angle that described rotating shaft is rotated is 5 ~ 10 °.
Compared with prior art, the beneficial effects of the utility model are:
Because the utility model is used for the control setup of elevator safety gear, be sleeve mechanism is moved on to sedan-chair from upper beam of the prior art at the bottom of, simplified connecting rod mechanism, use the welding of steel pipe simple in structure and sheet material, cooperate small and exquisite Compress Spring, greatly reduce the weight of link mechanism for elevator safety tongs, reduce the counterweight cost, energy savings is saved hoistway space and is convenient to on-the-spot maintenance and installation.

Fig. 1 is ascending for elevator, and Compress Spring suppresses the view of safety tongs and limit switch;
Fig. 2 is used during elevator falling, the view of safety tongs and limit switch action.
Among the figure:
1-the second safety tongs voussoir 2-the second safety tongs voussoir pull bar 3-rotating shaft
4-limit switch 5-driving lever 6-Compress Spring
7-the first safety tongs voussoir pull bar 8-fulcrum 9-the first safety tongs voussoir
10-expansion tightening wheel 11-speed limiter wire rope 12-velocity limiter wheel
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model is used for the control setup of elevator safety gear, comprise velocity limiter wheel 12, speed limiter wire rope 11, expansion tightening wheel 10, the first safety tongs voussoir 9, the second safety tongs voussoir 1 and safety tongs shift mechanism, described safety tongs shift mechanism comprises a rotating shaft 3, the first safety tongs voussoir pull bar 7, the second safety tongs voussoir pull bar 2 and a Compress Spring 6; The first safety tongs voussoir pull bar 7 and the second safety tongs voussoir pull bar 2 weld with the two ends of described rotating shaft 3 respectively, also be welded with a driving lever 5 in the described rotating shaft 3, the other end of described driving lever 5 contacts with the contact of limit switch 4, the first safe abaculus pull bar 7 is provided with a fulcrum 8, and this fulcrum 8 and described speed limiter wire rope 11 are hinged; One end of described Compress Spring 6 is fixed on the lift car, contacts at fulcrum 8 with bar section between the rotating shaft weld nugget on the other end of described Compress Spring 6 and the first safe abaculus pull bar 7.
As depicted in figs. 1 and 2, when elevator with command speed or up anxious stopping time of inspection speed, because mill guide rail even mistakenly stop ladder phenomenon that Compress Spring 5 starting forces greater than the force of inertia of velocity limiter wheel 12, expansion tightening wheel 10, speed limiter wire rope 11 and safety tongs shift mechanism, can avoid the upwards play of the first safety tongs voussoir pull bar 7 to cause.When the elevator overspeed descending, the velocity limiter action, clamp speed limiter wire rope 11, this speed limiter wire rope 11 is with respect to the first safety tongs voussoir pull bar 7 upward movements, therefore the first safety tongs voussoir pull bar 7 is lifted, therefore, (neutral angle of described rotating shaft rotation is 5 ~ 10 ° of scopes) are rotated in rotating shaft 3, thereby two the safety tongs voussoirs 9 and 1 that lift in linkage the second safety tongs voussoir pull bar 2, two safety tongs voussoirs pull bar 7 and 2 ends are held guide rail tightly, lift car slows down and finally stops gliding, meanwhile, because rotating shaft 3 is rotated, 4 actions of electric limiting switch, closing of circuit, towing machine stops operating.Falling of electric and mechanical duplicate protection lift car.
Although the above is described the utility model in conjunction with figure; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that do not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
