The 10th, protrude the bearing bracket of pair of right and left of movable pressing tablet 7a side of the pair of right and left of the fixedly pressing tablet 7 be arranged on pair of right and left; The 11st, be hubbed on the bearing bracket 10 of pair of right and left, at the connection shaft of the horizontally extending pair of right and left of fore-and-aft direction; 12 are arranged on the front of the adapter shaft 11 of pair of right and left, be configured in the reducing cam of the pair of right and left between the fixedly pressing tablet 7a of the movable pressing tablet 7 of pair of right and left and pair of right and left, 2 of periphery both sides separately respectively with the outer side contacts of the fixedly pressing tablet 7a of the inboard of the movable pressing tablet 7 of pair of right and left and pair of right and left.
At this, when normal circumstances, promptly when emergency braking apparatus 3 does not carry out the emergency braking action, reducing cam 12 tops of pair of right and left are upwards upright, the minor axis position of reducing contacts with the movable pressing tablet 7a of the fixedly pressing tablet 7 of pair of right and left and pair of right and left, in addition, the braking key 8 of pair of right and left is the movable pressing tablet 7a of pair of right and left with respect to framework 4, staggers specified amount and keeps to downside.At this moment, between the brake surface 8a of the braking key 8 of pair of right and left and guide pass 2a, form the space of predetermined distance.
When the emergency braking action of emergency braking apparatus 3, the reducing cam 12 of pair of right and left is applied in turning force, and top separately is oblique to guide pass 2a inclination.Thus, the major diameter position of the reducing cam 12 of pair of right and left contacts with the movable pressing tablet 7a of the fixedly pressing tablet 7 of pair of right and left and pair of right and left, the movable pressing tablet 7a of pair of right and left compares during with normal circumstances more to guide rail 2 side displacements, and the brake surface 8a of the braking key 8 of pair of right and left is pushed to guide pass 2a.In addition, the braking key 8 of pair of right and left constitutes: owing to and guide rail 2 between friction rise, and be pressed between the press surface 7b and guide pass 2a of movable pressing tablet 7a of pair of right and left, thereby come the decline of lift car 1 is braked.In addition, apply the structure of turning force, set forth in the back about reducing cam 12 a pair of to the left and right when emergency braking moves.
The 13rd, by the top and the below of the cam 12 that is arranged on pair of right and left, connect and first force body that constitutes by coil spring of the movable pressing tablet 7a of the fixedly pressing tablet 7 of the pair of right and left that furthers and pair of right and left, apply the load that makes that the movable pressing tablet 7a of the fixedly pressing tablet 7 of pair of right and left and pair of right and left contacts with the reducing cam 12 of pair of right and left always.In addition, because the reducing cam 12 of 13 pairs of pair of right and left of first force body is the power on the opposite hand of rotation when applying and moving with emergency braking, therefore can alleviate the misoperation of deliberately rocking etc. the emergency braking apparatus 3 that causes because of the passenger, and when emergency braking restores, make the reducing cam 12 of pair of right and left reset into upright normal position.
The 14th, second force body that constitutes by the compression spring between the inner end (the fixedly end opposite of pressing tablet 7 sides) of the pressing body 5 that is arranged on pair of right and left, to make pair of right and left toward each other fixedly pressing tablet 7 mutually away from the direction application of force.The 15th, by being screwed in the framework 4, be configured in the retainer that the bolt in the inner end outside of the pressing body 5 of pair of right and left constitutes, will stop at assigned position all the time by the rotation displacement of the pressing body 5 of the pair of right and left of 14 application of forces of second force body.Thus, when normal conditions, promptly the reducing cam 12 of pair of right and left upright the time, the press surface 7b of the movable pressing tablet 7a of pair of right and left is maintained at the assigned position place of leaving with guide pass 2a respectively, and the gap between the brake surface 8a of the braking key 8 of guide pass 2a and pair of right and left is remained on predetermined distance.In addition, second force body 14 overcomes owing to the open power in gap between the front end of the pressing body 5 of braking key 8 rising fixedly pressing tablets 7 that produce, that make pair of right and left and pair of right and left when emergency braking moves.
The rotating mechanism of the reducing cam 12 of the pair of right and left when then, emergency braking being moved describes.
16 are arranged on adapter shaft 11 ends of pair of right and left, and leading section is to the lifting rod of the pair of right and left of the peripheral direction extension of this adapter shaft 11, leading section separately is when normal conditions, promptly when the reducing cam 12 of pair of right and left is upright, oblique below towards fixedly pressing tablet 7 sides of pair of right and left, by lifting, the reducing cam 12 of pair of right and left is tilted.The 17th, vertical extent on above-below direction, the lower end be arranged on pair of right and left lifting rod 16 leading section pair of right and left lift rod, though omitted the detailed formation explanation in upper end, the upper end is provided with when the abnormal speed of lift car 1 descends by the governor action and the structure above being pulled to.Thus, when emergency braking moved, the displacement that lifts rod 17 last direction of pair of right and left was transformed to the rotation of the reducing cam 12 of the adapter shaft 11 of lifting rod 16, pair of right and left of pair of right and left and pair of right and left.
The 18th, protrude the block of pair of right and left on the front surface top of the movable pressing tablet 7 be arranged on pair of right and left, when emergency braking moves, by with the upper surface butt of the lifting rod 16 of pair of right and left, prevent the rotation of the reducing cam 12 of pair of right and left.In addition, when emergency braking moves, by pair of right and left lift the rod 17, reducing cam 12 rotations of pair of right and left, the brake surface 8a of the braking key 8 of pair of right and left and guide pass 2a butt, and pair of right and left lift rod 17 in the moment of having risen small quantity, the block 18 of pair of right and left prevents the rising of the lifting rod 16 of pair of right and left.At this moment, the reducing cam 12 of pair of right and left always is compressed the application of force of spring 14 at compression direction across the fixedly pressing tablet 7 of pair of right and left and the movable pressing body 7a of pair of right and left.The masterpiece of this compression direction is used for horizontal direction, when the contact point between the movable pressing tablet 7a of the fixedly pressing tablet 7 of the pair of right and left of the reducing cam 12 of pair of right and left and pair of right and left is in in opposite directions position of the horizon by rotating shaft center respectively, rotational force is had an effect on the reducing cam 11 of pair of right and left, therefore, two contact points are positioned at upside or downside with respect to the horizon by rotating shaft center.
In addition, this emergency braking apparatus 3 is the emergency braking apparatus 3 shown in the figure, and is corresponding with the guide rail 2 of the both sides that are configured in lift car 1, is configured in the both sides of lift car 1.The adapter shaft 11 of the pair of right and left of installing at reducing cam 12 head lamp brush guard pivots of the pair of right and left of a side emergency braking apparatus 3 also with reducing cam 11 pivotal mounting of the pair of right and left of the opposing party's emergency braking apparatus, rotation interlock with a side cam, the reducing cam 12 of the opposing party's pair of right and left also rotates, so the opposing party's emergency braking apparatus 3 also carries out identical action.
Use the action example of Fig. 3~elevator emergency brake device 3 that Fig. 5 explanation constitutes as mentioned above.
When the normal circumstances that elevator turns round medium, as shown in Figure 3, the reducing cam 12 of pair of right and left is upright, in addition, the braking key 8 of pair of right and left is maintained at framework 4, be the lower position of the movable pressing tablet 7a of pair of right and left, the brake surface 8a of the braking key 8 of pair of right and left is configured to be contactless state with guide pass 2a.
