As Figure 1-3, the elevator door locking device that a kind of people of preventing falls, this elevator door is comprised of door and mechanical controller structure.
Elevator door comprises left fan door 1 and right wing door 10, and mechanical controller structure comprises vertical beam a2, vertical rod 3, elastic webbing 4, portable bar 5, strut bar 6, push rod 7, lock dog 8, vertical beam b9, spring a11, top board 12, spring b13, portable plate 14, connecting rod 15, side plate 16, spring-support plate 17, flow regulating valve 18, cylinder 19, piston rod 20, piston 21, spring c22, deflation hole 23, fixed link 24, slideway 25, push rod 26, block 27, pin 28; Vertical beam a2, vertical rod 3 and strut bar 6 are arranged on left fan door 1, and vertical beam b2 and lock dog 8 are arranged on right wing door 10; Between vertical beam a2 and vertical beam b9, connect an elastic webbing 4; Vertical rod 3 is provided with hole, and one end of portable bar 5 is connected with the hole of establishing in vertical rod 3 by pin, and the other end of portable bar 5 is provided with a crooked latch hook, relies on self gravitation to hook lock dog 8; When strut bar 6 guarantees locking, the height of the left fan door 1 of portable bar 5 distance is consistent; Portable bar 5 is provided with crooked rope hook end and is provided with push rod 7 and is in contact with it; Push rod 7 is fixing with spring-support plate 17, and spring-support plate 17 is fixed on piston rod 20.
Described piston rod 20 bottoms are provided with piston 21, and piston 21 can be in the interior slip of cylinder 19; Cylinder 19 is fixed on the elevator borehole wall; Described cylinder 19 tops are provided with one-way throttle valve 18; Between piston 21 and cylinder 19 bottoms, be provided with spring c22; In the middle of the bottom of cylinder 19, be provided with deflation hole 23; Piston rod 20 tops are provided with portable plate 14, and described portable plate 14 can be free to slide along piston rod 20, and portable plate 14 is free-running fit with piston rod 20, and portable plate 14 is fixed on top board 12 by spring b13; Portable plate 14 on described piston rod 20,17 of spring-support plates connect by spring a11; In portable plate 14 bottom one sides and connecting rod 15 1 end in contact; Connecting rod 15 can be connected to by middle bearing pin on fixed link 24, and fixed link 24 is arranged horizontally, and connecting rod 15 can rotate freely around bearing pin, and connecting rod 15 bottoms are connected with push rod 26, and the slideway 25 that push rod 26 can along continuous straight runs be arranged slides; Described push rod 26 is an elongate recesses with connecting rod 15 junctions, and the pin 28 of push rod 26 can be free to slide in the groove of connecting rod 15 junctions, avoids this device to be stuck in motion process; Side plate 16 is arranged on lift car, and block 27 is installed on side plate 16; Described block 27 is one irregularly shaped, on one side its cross section is isosceles trapezoid, Yi Bian be rectangle.
When arriving, lift car is not provided with while preventing elevator door floor that people falls, block 27 does not contact push rod 26, under the effect of spring a11 and spring b13, piston rod 20 promotes piston compression spring c22, push rod 7 and portable bar 5 no touchs, under Action of Gravity Field, portable bar 5 fastens lock dog 8, and elevator door is in locking state; Now no matter apparatus for controlling elevator lost efficacy or human operational error, as long as lift car does not arrive elevator door place floor, elevator door cannot be opened.
When elevator arrives elevator door place floor, block 27 contacts and drives push rod 26 horizontal motions with push rod 26, push rod 26 promotes connecting rod 15 and rotates around fixed link 24, connecting rod 15 promotes it along piston rod 20 Compress Spring b13 with portable plate 14 contact jaws, spring a11 is stretched, piston rod 20 moves under the effect of spring c22, because cylinder 19 tops are provided with one-way throttle valve, guarantee the steady of piston rod 20 motion processes, push rod 7 is with piston rod 20 motions, push rod 7 will back down portable bar 5, force portable bar 5 to rotate around vertical rod 3, the latch hook end of portable bar 5 and lock dog 8 are thrown off, now elevator door can be opened under the driving of car door motor, in elevator door opening procedure, piston rod 5 is supported by strut bar 6, when elevator door cuts out, latch hook end and the lock dog 8 of portable bar 5 all have slope, and portable bar 5 slips over behind slope in preparing locking state.
When lift car leaves elevator door place floor, block 27 is thrown off with push rod 26, under the effect of spring a11 and spring b13, piston rod 20 Fast Compression spring c22, push rod 7 moves down, and portable bar 5 is under the effect of gravity, its latch hook end pins lock dog 8, makes elevator door in locking state.
When lift car is through elevator door place floor but not when this floor stops, block 27 promotes 26 parallel motions, connecting rod 15 promotes portable plate 14 Compress Spring b13, piston rod 20 promotes push rod 7 motions in the effect of spring c22, because cylinder 19 tops are provided with one-way throttle valve 18, piston rod 20 motion processes are steady; Because car is greater than device reaction speed by elevator door place floor speed, before the latch hook of portable bar 5 being backed down at push rod 7 to disengaging lock dog 8, block 27 just departs from push rod 26, under the effect of spring a11 and spring b13, piston rod 20 continues Compress Spring c22, the latch hook of portable bar 5 continues locking lock dog 8, and elevator door is still in locking state.
When car motor fails elevator door to cut out and car during not at elevator door place floor, elevator door cuts out two fan doors under elastic webbing 4 effects of left fan door 1 and the 10 tops installations of right wing door, when elevator door cuts out, the latch hook of portable bar 5 is locked lock dog 8 equally.
Stuck while promoting connecting rod 15 for anti-throw-out lever 26, connecting rod 15 have groove with push rod 26 junctions, push rod 26 is when promoting connecting rod 15 and rotating, pin 28 slides along chute, thereby avoids push rod 26 and connecting rod 15 stuck.
The above specific embodiment is used for the utility model of explaining, rather than the utility model is limited.In the protection domain of design philosophy of the present utility model and claim, the utility model is made to any modification or change, all should be considered as protection domain of the present utility model.
