Described wiring partly comprises housing 2 and is arranged at two the wiring gears 5 in the housing 2, two contact roller devices 7, two springs 3 and conductor rope covers 4, two wiring gears 5 are meshing with each other, and the output gear of one of them wiring gear 5 and described running part is meshing with each other.Described conductor rope cover 4 is arranged at the end face of two wiring gears 5, and link to each other with two wiring gears 5, described two contact roller devices 7 are arranged at two wiring gears, 5 sides respectively, one end and the described housing 2 of two contact roller devices 7 are hinged, the other end is hinged with an end of described two springs 3 respectively, the other end of two springs 3 and described conductor rope cover 4 are hinged, and two contact rollers of two contact roller devices 7 are pressed on respectively in the wiring groove of two wiring gears 5.
First worm screw 907, second worm screw 908, two gears 909 and the output gear shaft 905 of described running part constitute brake portion together; Wiring gear driven output gear shaft 905 counter-rotatings under two foot-operated 1 no longer rotations, the action of gravity of wiring part in load, second worm screw 908 reverse simultaneously, (two gears 909 all are imperfect gear, it respectively has a backing pin can doing on first worm screw 907 and second worm screw 908 on 180 ° the end face of reciprocal rotation, first worm screw 907 and second worm screw 908), make second worm screw 908 and first worm screw 907 produce axial self-lockings, realize braking.
Described clutch for clutch control partly comprises first friction lining 904, second friction lining 902, disk spring 903, quadrant gear 11, sector shaft 10, clutch controller 12, thrust baring 13, control handle 14 and spring 8, first friction lining 904 is arranged on described second worm screw, 908 mouths, second friction lining 902 and disk spring 903 are embedded in the input end of output gear shaft 905, first friction lining 904, second friction lining 902 and disk spring 903 constitute a power-transfer clutch, described sector shaft 10 is installed on the housing 2, quadrant gear 11 is installed on the sector shaft 10, control handle 14 1 ends are fixedly mounted on the sector shaft 10, the other end links to each other with described housing 2 by spring 8, clutch controller 12 places quadrant gear 11 sides, clutch controller 12 is threaded on the described housing 2, thrust baring 13 withstands on the described output gear shaft 905, and places clutch controller 12 front sides.
Clutch occurs in the place that first friction lining contacts with second friction lining, when disk spring is in compacted state, just can be in running order under the effect of first friction lining and second friction lining, and promptly power-transfer clutch is in the state of " closing "; Otherwise just be in off working state, promptly be in " from " state.Compress and the relaxation state of disk spring are realized by rotating control handle, control handle drives the rotation of quadrant gear by sector shaft, gear mesh on quadrant gear and the clutch controller, the drive clutch controller rotates, the clutch controller that is contained in by being threaded on the described housing moves along hand of spiral owing to rotate, thereby compresses or loosen disk spring by withstanding on output gear shaft on the thrust baring.
Imput shaft can be by people's direct drive.In working order, imput shaft 906 drives two gears, 909 transmissions that are contained on first worm screw 907 and second worm screw 908 simultaneously, thereby driven the rotation in the same way of first worm screw 907 and second worm screw 908, first worm screw 907 is by being passed to power on the output gear shaft 905 by first friction lining 904, second friction lining 902 and disk spring 903.
Steel rope is in the wiring groove of two wiring gears 5.The cross section of the wiring groove of wiring gear 5 is shape in echelon, and steel rope is pressed tight more therein more, thereby guarantees do not have slide relative between steel rope and the wiring gear, promptly can not skid.Two contact roller devices 7 have been controlled the cornerite of steel rope in the wiring groove, thereby have determined the driving efficiency of this part.Conductor rope cover 4 can guarantee that reeve carries out smoothly on wiring gear 5, and can prevent to run out of the wiring groove when rope is in relaxed state.
Principle of work:
The utility model gear on worm self-locking type gig mainly can be realized three functions: the first, and the people is stepping on foot-operated can up walking, and can self-locking be parked in original position when not stepping on; The second, counter the stepping on of people ridden and can be walked downward, and can self-locking be parked in original position when not stepping on; The 3rd, can free low-tach walking downward.We are called the in running order function of this elevator to two functions in front, and last function are referred to as the function of off working state.Below I will introduce the principle that realizes these functions:
The realization principle of first kind of function is: when the people steps on when foot-operated, step on foot-operated power and be amplified to the gravity that is enough to overcome whole elevator by the series of gears transmission, thereby can up walk.When the people does not step on when foot-operated, have under the situation of self-locking action two worm meshs, overcome the gravity of entire machine, thereby made lift in position.
The realization principle of second kind of function is the same with first kind.
The realization principle of the third function is: when the staff draws control handle toward self direction, power-transfer clutch be in " from " state, the i.e. rotation of two wiring gears 5 does not at this moment have influence on the transmission in the spindle stock, machine will speed up the whereabouts: when staff's release on control handle, power-transfer clutch is in the state of " closing ", the machine whereabouts of will slowing down.So the staff can control the whereabouts of elevator by control handle.
