Between frame, the lead screw bottom end of wherein at least one group hand-clamping preventing mechanism also passes through the nut handrail emergency stop that is fixedly clamped and hits plate, emergency stop
Switch, which is arranged in handrail emergency stop and hits the switch terminals of plate lower part and emergency stop switch, hits plate setting, emergency stop switch side towards handrail emergency stop
It is fixed on the control handwheel frame by handrail emergency stop bracket.
The lead screw passes through the handrail emergency stop and hits plate setting.
The lead screw is additionally provided at least one nut connected to it in anti-pinch handrail spring top.
The beneficial effects of the utility model are: it is reasonable in design, passenger can be played by hand-clamping preventing mechanism anti-
Shield effect in emergency circumstances can carry out emergency braking to screw rod ladder, can greatly improve the safety of passenger.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the left view structural representation of the utility model.
Fig. 3 is the partial enlargement structural representation of " A " in Fig. 1.
In figure: 1 anti-pinch handrail, 2 control handwheel frames, 3 spring lower plates, 4 handrail emergency stops hit plate, 5 anti-pinch handrail springs, 6 spiral shells
Female, 7 handrail emergency stop brackets, 8 emergency stop switch, 9 lead screws.
Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
As shown in Figure 1 to Figure 3: the present embodiment provides a kind of screw rod ladder rail emergency stop devices, including anti-pinch handrail 1, manipulation
Disk frame 2 and four groups of hand-clamping preventing mechanisms.
The hand-clamping preventing mechanism includes spring lower plate 3, anti-pinch handrail spring 5 and lead screw 9,9 top of lead screw with it is described
1 bottom of anti-pinch handrail is connected and fixed, and 9 lower part of lead screw sequentially passes through 2 top of control handwheel frame and spring lower plate 3 is arranged, control handwheel
2 top of frame is equipped with the through-hole that setting is passed through for lead screw 9, and spring lower plate 3 is fixed on the through-hole lower part of control handwheel frame 2, silk
9 bottom end of thick stick is equipped with nut 6, and nut 6 contacts to form bottom end limit with spring lower plate 3, passes through anti-pinch handrail spring 5 in the middle part of lead screw 9
Setting, for anti-pinch handrail spring 5 between anti-pinch handrail 1 and control handwheel frame 2, the setting of above structure makes anti-pinch handrail 1 can
To be oriented to and move down by lead screw 9 under external force, while anti-pinch handrail spring 5 is compressed, when external force disappears, compression
Anti-pinch handrail spring 5 rebounds, and can reset to lead screw 9 and anti-pinch handrail 1；
Further, lead screw 9 is additionally provided with two nuts 6 connected to it, two nuts 6 in 5 top of anti-pinch handrail spring
Compression anti-pinch handrail spring 5 can be rotated down and compress, for controlling the height in space locating for compression anti-pinch handrail spring 5,
The decrement of compression anti-pinch handrail spring 5 is adjusted, ensures compression 5 operation in effective length of anti-pinch handrail spring；
Wherein, there are two the nut 6 positioned at 9 bottom end of lead screw of two groups of hand-clamping preventing mechanisms of two sides is set, and two nuts 6 it
Between the handrail emergency stop that is fixedly clamped hit plate 4, lead screw 9 passes through the handrail emergency stop and hits the setting of plate 4, and the setting of emergency stop switch 8 is being helped
Hand emergency stop hits 4 lower part of plate and the switch terminals of emergency stop switch 8 hit the setting of plate 4 towards handrail emergency stop, and 8 side of emergency stop switch passes through handrail
Emergency stop bracket 7 is fixed on the control handwheel frame 2, in screw rod ladder operational process, when people station in carriage, if accidentally
When hand is reached in the gap between Knapsack-rack and screw rod, hand can be pressed onto anti-pinch handrail 1, sink after 1 stress of anti-pinch handrail, make handrail
Emergency stop hits plate 4 and touches emergency stop switch 8, by connecting emergency stop switch 8 into the safety return circuit of screw rod ladder, so that emergency stop switch 8
Movement can allow screw rod ladder out of service.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the protection scope of the utility model.
