Description
Technical field
The utility model relates to a kind of velocity limiter-safety tongs system interlink overspeed protection device, more particularly, relates to the descending overspeed protection device of a kind of Elevator weight sensor device or car.
Background technology
At present, the descending velocity limiter of elevator-safety tongs system interlink overspeed protection device of selling on the market and using, owing to there is complex structure, problem such as volume is bigger generally is only applicable to be installed in the bottom of car frame crossbeam, bears the overspeed protection of car.And some building requires middle building section that elevator is installed; the below floor that elevator is installed exists under the situation in personnel activity space; standard-required according to GB7588-2003 " manufacturing of elevator and installation safety standard "; just must on counterweight, install a cover velocity limiter-safety tongs system interlink overspeed protection device, or solve by the way of building solid wall pier at the counterweight lower zone.Because the volume of the velocity limiter-safety tongs system interlink overspeed protection device that uses is bigger at present, installs velocity limiter-safety tongs system interlink overspeed protection device and have certain limitation on counterweight.
Summary of the invention
The purpose of this utility model provides a kind of velocity limiter-safety tongs system interlink overspeed protection device that can be easily installed on the counterweight.
This is suitable for later-model purpose and is achieved through the following technical solutions: it comprises velocity limiter, traction steel-cable, fixed mount, carriage and electric switch, it is characterized in that, also be provided with safety tongs, lifting rod, the axis of guide, Z font connecting arm, discharge axle, reset folder axle sleeve, described fixed mount and carriage left-right symmetric respectively are installed in the lower end of counterweight framework, are connected with counterweight framework and safety tongs by screw; The described axis of guide is installed in the vertical core on the carriage, axis of guide bottom with the nut fixing and locking on carriage; Described Z font connecting arm one end links to each other with traction steel-cable by rope clamp, and the other end is connected by the bearing pin on waist shaped hole and the lifting rod; Matching with axle sleeve on the fixed mount by bearing in the described axle two ends, the left and right sides that discharge, and is connected with the lifting rod of left-right symmetric installation respectively by elastic cylindrical pin; The described folder that resets is fixed on the carriage by bent plate, and described electric switch is fixed on the carriage by bent plate, switch contact be fixed on the axle sleeve that discharges on the axle outward garden breach U profile contact.
Described release axle centre portion is square, and two ends are circular.
The described folder that resets can be made up of the waist type projection and the two clamping plates of a compression spring, a symmetry, and its middle part of the side shape projection is screwed on the square shaft that discharges axle, and two clamping plate are clamped the two sides of waist shape projection.
This suitable new structure is simple, and volume is little; Can realize putting or being inverted installation, install easy to adjust; Low cost of manufacture.Not only can be easily installed on the Elevator weight sensor device, also be applicable to be installed on the car, play the effect of descending overspeed protection.
Description of drawings
Fig. 1 is the lateral plan of the utility model one embodiment;
Fig. 2 is the perspective view of safety tongs embodiment illustrated in fig. 1 system;
Fig. 3 is the local structure enlarged diagram of safety tongs shown in Figure 2 system.
Among the figure: 1. velocity limiter; 2. steel rope; 3. counterweight; 4. safety tongs; 5. lifting rod; 6. the axis of guide; 7. connecting arm; 8. discharge axle; 9. folder resets; 10. electric switch; 11. elastic cylindrical pin; 12. safety tongs roller; 13. fixed mount; 14. carriage; 15. axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing, present embodiment comprises velocity limiter 1, traction steel-cable 2, safety tongs 4, lifting rod 5, the axis of guide 6, Z font connecting arm 7, release axle 8, folder 9, fixed mount 13, carriage 14, axle sleeve 15 and electric switch 10 reset; Described fixed mount 13 and carriage 14 left-right symmetric respectively are installed in the lower end of counterweight 3 frameworks, are connected with counterweight 3 frameworks and safety tongs 4 by screw; Matching with axle sleeve on the fixed mount 13 by bearing in the described axle two ends, 8 left and right sides that discharge, and is connected with the lifting rod 5 of left-right symmetric installation respectively by elastic cylindrical pin 11, and lifting rod 5 links to each other with the roller 12 of safety tongs 4; Described Z font connecting arm 7 one ends link to each other with traction steel-cable 2 by rope clamp, and the other end is connected by the bearing pin on waist shaped hole and the lifting rod 5, and the axis of guide 6 is housed on the carriage 14; The described folder 9 that resets is fixed on the carriage 14 by bent plate, and described electric switch 10 is fixed on the carriage 14 by bent plate, switch contact be fixed on the outer garden breach U profile that discharges the axle sleeve 15 on spools 8 and contact.
Described release axle 8 centre portions are square, and two ends are circular.
