Description
Technical field
The present invention relates to a kind of elevator governor, especially the velocity limiter of machine-roomless lift.
Background technology
Velocity limiter is a kind of safety component that is used to control elevator speed.When elevator operation hypervelocity reached governor tripping speed, velocity limiter by the electric switch action, cut off the elevator traction machine working power earlier; As continue hypervelocity and reach the mechanical device responsiveness, mechanical flip flop equipment action, rope gripper is clamped steel rope, makes the safety device action, mentions safety tongs stop car.
Have machine room time limit speed device generally to be installed in the machine room at elevator, the engineering staff can be approaching, observes, tests and reset all more conveniently, and tension force of steel wire clamps steel rope by cord-pressing block and realizes.Unclamp velocity limiter, need prize cord-pressing block with instrument, for the machine-roomless lift velocity limiter that is installed in the hoistway, the engineering staff is difficult to approaching and certain danger is arranged.And these adopt velocity limiter complex structure, the adjustment inconvenience of cord-pressing block.
Summary of the invention
The purpose of this utility model provides a kind of machine-roomless lift velocity limiter, simple in structure, the convenient adjustment, and it can be installed in the hoistway, test and outside hoistway, velocity limiter is moved under lower speed, and the test back is electric and resetting of mechanical device also finished outside hoistway by automatically controlled mode.
The technical solution of the utility model: this velocity limiter comprises the rope sheave that is installed on the velocity limiter support, re-packing of control electric switch action, adjustable latch hook, re-pack and latch hook is arranged on the outer concentric circumferences of rope sheave, re-pack and rope sheave between distance less than the distance between latch hook and the rope sheave, radially be provided with guide holder on the rope sheave, in the pilot hole of guide holder pin is arranged, the vertical pin of guide rod is fixed on the rope sheave, the hinged respectively pin in connecting rod two ends and be socketed in slide on the guide rod slidably, be provided with elastic element between the adjustment nut on slide and the guide rod, the fastener that can fasten with latch hook is arranged on the pin.
The utility model is simple in structure, mainly form by pin, connecting rod, some linings etc., make easily, speed is easy to adjust, thickness is less, and hoistway is easy for installation, and cost is lower, the control button that resets of electric switch and latch hook setting device can be installed in outside the elevator hoistways simultaneously, carry out Long-distance Control.So just can long-rangely test and reset, reduce the number of times that engineering, testing crew enter hoistway.
Description of drawings
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, the machine-roomless lift velocity limiter of present embodiment comprises the rope sheave 1 that is installed on the velocity limiter support 7, what control electric switch 9 moved re-packs 10, adjustable latch hook 17, the axis hole of rope sheave 1 bearing of packing into, sheave shaft 3, wheel hub end housing 4, re-pack 10 and latch hook 17 be arranged on the outer concentric circumferences of rope sheave 1, re-pack 10 and rope sheave 1 between distance less than the distance between latch hook 17 and the rope sheave 1, radially be provided with two guide holders 5 on the rope sheave 1, lay respectively at the both sides up and down of sheave shaft 3, the pilot hole of guide holder 5 lining 11 of packing into, pin 2 flexible motion vertically in lining 11, two guide rod 14 vertical pins 2 are fixed on the rope sheave 1, and lay respectively at the left and right sides of sheave shaft 3, four hinged respectively pins 2 in connecting rod 15 two ends and be socketed in slide 13 on the guide rod 14 slidably, be provided with elastic element 19 between the adjustment nut 18 on slide 13 and the guide rod 14, the fastener 21 that can fasten with latch hook 17 is arranged on the pin 2.This moment, whole connecting rod mechanism should be able to flexible motion, checked that the pin both ends guarantee radially on a circumference.
Governor sheave clockwise turns to the car down direction as shown in Figure 1.Pin 2 is subjected to the effect of spring 19 to be in shown position when car stops.Owing to making pin 2, action of centrifugal force outwards moves when car is descending along lining, 4 pull bars 15 haul guide holder 13 and move to axis direction along guide rod 14, compression spring 19, spring pressure is increased, reach new balance with centnifugal force, therefore, the big more centnifugal force of speed is big more, pin 2 moves radially displacement and increases, and spring 19 pressure also become big.When speed reaches the setting value of electric switch action, pin 2 bumps re-pack and 10 make electric switch 9 outages, cut off host power supply, and forward and reverse rotation can make electric switch 9 actions.The re-pack responsiveness of the whole electric switch of adjustable positions of 10 relative pins 2 of adjustment.Increase with speed, pin 2 continues to yearn for mobile, the pin 2 that latch hook hooks when reaching the mechanical device responsiveness, and rope sheave 1 stops operating, and steel rope produces tensile force and makes the safety device action.
Only need inverted running when resetting, mention car and make governor sheave 1 left-hand revolution, latch hook and pin 2 are thrown off naturally, avoid the engineering staff to enter hoistway and produce dangerous.Pin 2 is got back to the normal position under the effect of spring 19, mechanical return is finished; Re-packing 10 is automatically reset by deadweight, and press the electrical reset button this moment outside hoistway reset electric switch 9.Can under lower speed, carry out the linkage test of safety device again by the electromagnetic valve button jack-up latch hook of lower support latch hook 17.
