[technical field]
The utility model relates to elevator safety component technology field, specifically a kind of elevator-distance switch of high safety factor.
[background technology]
Elevator-distance switch is one of elevator safety critical piece; present safety device switch is installed on the limiter of speed, plays that elevator is in service to play a protective role, owing to can only play a protective role in elevator is descending; yet run into when out of control at ascending for elevator, but can not play a protective role.Has the device that can prevent that ascending for elevator is out of control though occurred a kind of elevator-distance switch at present, but also have many weak points: the designed closed disconnecting apparatus of this elevator-distance switch needs the very big pressure impulse force of bent plate it could be become disconnect or closure state, be easy to break down after having grown service time like this, cause the elevator can't operate as normal, all bring very big inconvenience for people and its maintenance man of taking a lift, even dangerous situation can occur.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and the elevator-distance switch of a kind of high safety factor of providing; novel structure, simple; the designed closed disconnecting apparatus of forming by turnover panel, torque spring, movable contact plate, static contact panel, pin; bent plate only needs very little pressure impulse force just can make it become to disconnect or closure state; use as safe as a housely, reliable, the provisional capital plays a very good protection under the ascending for elevator.
Design a kind of elevator-distance switch of high safety factor for achieving the above object, comprise base, pedestal, housing, connecting rod, contact holder, bent plate, catch members, have circular hole 29 and cross recess 28 on base 9 bottom faces, have circular hole 27 on the base 9 front and back side plates, base 9 adopts bolt to connect pedestal 2, pedestal 2 inside are cavity, have circular hole on the front and back side plate of pedestal 2 lower-left ends, bearing pin 3 is housed in the circular hole, be with connecting rod 4 on the bearing pin 3, connecting rod 4 right-hand member connecting terminal supports 5, contact holder 5 right-hand members connect catch members 17, the upper surface of catch members has round taper hole 12, the lateral surface of round taper hole 12 snaps in an end that connects spring 6, the other end of spring 6 is fixed on the bottom face of pedestal 2, the right-hand member of catch members connects bent plate 7, have circular hole in the middle of the bent plate 7, axle 8 is housed in the circular hole, the two ends of axle 8 are fixed in the circular hole 27 of base 9 front and back side plates, contact holder 5 upper surfaces have circular hole, bearing pin 19 is housed in the circular hole, be with moving contact plate 20 and spring 23 on the bearing pin 19, the two ends of bearing pin 19 are provided with dome 22, the contact of moving contact plate 20 is connected with the contact of fixed contact plate 13, fixed contact plate 13 is fixed on the upper surface of pedestal, it is characterized in that bent plate 7 left upper ends are provided with a circular arc projection 26, the front and back side plate of pedestal 2 bottom righthand sides adopts pin 24 to connect turnover panel 15, torque spring 16 is housed on the pin 24, turnover panel 15 is provided with a block 14, turnover panel 15 left sides connect movable contact plate 21, the contact of movable contact plate 21 upper ends is connected with the contact of static contact panel 18, and static contact panel 18 is fixed on the upper surface of pedestal 2; Pedestal, turnover panel and contact holder adopt plastics or insulating material to make; The movable contact plate adopts phosphorus bronze sheet to make; The shell right side has circular hole, and card has rubber washer in the circular hole.
During the utility model normal condition, bent plate is in vertical position, and left end contact and closed disconnecting apparatus are normally off, when elevator descending when out of control, centrifugal device on the limiter of speed moves the lower end of bent plate to the right, and the left end contact of elevator-distance switch disconnects, and cuts off the electricity supply; When ascending for elevator is out of control, centrifugal device on the limiter of speed moves the lower end of bent plate to the left, the circular arc projection of bent plate upper end is pressed on the block of turnover panel, make closed disconnecting apparatus become off-state, connect the ascending for elevator emergency braking device, the left end contact of elevator-distance switch disconnects simultaneously, cuts off the electricity supply.The initial state of closed disconnecting apparatus of the present utility model is a normally open if desired, then places the right side to get final product the circular arc projection when bent plate is installed.
The utility model compared with prior art, structural design novelty, simple, safety, reliable plays a protective role when not only elevator is descending, and also can play a protective role during ascending for elevator, has guaranteed the coefficient of safety of elevator more, is worthy of promotion and application.
