Description

A kind of overpass elevator

Technical field

The utility model relates to a kind of public facility of crossing street, specifically relates to one and can replace existing general mistakeStreet overline bridge, facilitate disabled person and handicapped old man's overpass elevator, comprise a horizontal well channel and two vertical hoistways, sedan-chairRailway carriage or compartment, draw-gear, cross slide way and upright guide rail, lift car can pass through transversely guide rail and upright guide rail of draw-gearVertical and move horizontally.

Background technology

At some bustling crossings, street, blocking up of traffic increased the weight of on pavement, and the appearance of overpass has solved thisProblem, for some disabled persons and handicapped old man, climbs up the stair of overpass and is not easy, although presentOverpass has added elevator or other similar lowering or hoisting gears of some escalator-types, but also just plays the merit of guidingCan, the difficulty that disabled person and handicapped old man remain unchanged very by such overpass. The utility model is by common electricityLadder combines with cable car, and disabled person as long as taking common car type elevator, presses elevator life with handicapped old manMake button, herein, car opens the door elevator car arrives, and people enters car, and after a period of time, car is closed the door, and elevator just send passengerTo the opposite of road. The purpose of this utility model is to provide a kind of disabled person of help or handicapped old man need not walk commonStair and arrive road opposite, equally also can facilitate general pedestrian to reach to substitute the overpass elevator of existing common overpass.The utility model can be used as the overpass elevator of busy street crossroad, city, to replace crossing, reduces traffic congestion.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described further

In conjunction with Fig. 1 and Fig. 2, in figure, 1 is vertical hoistway, and 2 is horizontal well channel, and 3 is car, and 4 is sedan-chair frame, and 5 is draw-gear,6 is cross slide way, and 7 is upright guide rail, and 8 is layer door, and 9 is hoist ropes, and 10 is gear, and 11 is horizontally tracting motor, and 12 is verticalTraction electric machine, 13 and 14 is motor base, and 15 is draw-gear base, and 16 is traction sheave, and 17 is traction wheel shaft, 18 and 22 for rollingDynamic bearing, 19 is traction gear, and 20 is connecting plate, and 21 is bolt, and 23 is traction teeth wheel shaft, and 24 is pulley, and 25 is pulley bearings,26 is pulley spindle, and 27,28,29 and 30 is belt pulley, and 31 and 32 is driving belt, and 33 is link.

In conjunction with Fig. 1 and Fig. 2, horizontally tracting motor 11 and vertical distraction motor 12 are separately fixed at motor base 13 and 14Upper, motor base 13 and 14 is fixed on draw-gear base 15, and traction sheave 16 is pacified by traction wheel shaft 17 and rolling bearing 18Be loaded on connecting plate 20, traction gear 19 is installed on connecting plate 20 by traction teeth wheel shaft 23 and rolling bearing 22, and pulley 24 passes throughPulley spindle 26 and pulley bearings 25 are installed on link 33, and link 33 uses bolt 21 to be fixed on connecting plate 20, belt pulley27 are arranged on vertical distraction motor 12, and belt pulley 28 is arranged on traction wheel shaft 17 one end, and vertical distraction motor 12 is by transmissionThe rotation of belt 32 drives traction sheave 16 to rotate, and traction sheave 16 can pull lift car 3 along vertically leading by hoist ropes 9Rail 8 moves both vertically; Belt pulley 29 is arranged on horizontally tracting motor 11, and belt pulley 30 is arranged on traction teeth wheel shaft 23 one end, horizontal strokeTwice pulley groove is arranged at the top of direction guiding rail 7, and the pulley 24 of elevator driving device 5 can slidably reciprocate on pulley groove, laterally leadsOne toothrow wheel 10 is arranged at rail 7 bottoms, and the gear of cross slide way bottom and 19 engagements of the traction gear of draw-gear contact, horizontally tractingMotor 11 drives traction gear 19 to rotate by driving belt 31, and the rotation of traction gear 19 makes transversely guide rail water of car 3Flat motion.

In conjunction with Fig. 1 and Fig. 2, when initial, lift car 3 is positioned at A place, when having people after A place is by the startup command of elevator, electricityLadder layer door 8 will be opened, and people enters after lift car 3, and elevator door 8 is closed, and at this moment the controller of elevator will be controlled vertical distractionMotor rotates with certain speed, thereby draw-gear will give lift car with tractive force vertically upward, when lift car arrivesWhile reaching B place, the controller of elevator will make vertical distraction motor stop operating, controller by level of control traction electric machine with certainSpeed is rotated, thereby draw-gear will give lift car with parallel tractive force left, when lift car is along guide rail movement to C, the controller of elevator will make horizontally tracting motor stop operating when at the place, and then, controller will be controlled vertical distraction motor with necessarilySpeed rotate, the draw-gear of elevator by lift car with certain speed slowly land to D place, elevator door will be opened,People can be from elevator out, and after a period of time, elevator door will be closed, and one time running process of elevator finishes. At elevator motionIn process, the movement velocity of car is to be realized by the velocity of rotation of controller level of control traction electric machine and vertical distraction motor, in the time that car soon arrives A, B, these node locations of C, D, controller can reduce horizontally tracting motor or vertical distraction motorVelocity of rotation, car safety is stopped at node location reposefully.
