Description
Technical field
This utility model is related to a kind of elevator, more particularly to a kind of elevator memorial archway depth indicator.
Background technology
Prior art memorial archway type depth indicator, the rotation of main shaft of hoister is passed to depth indicator by power transmission shaft, makes
Two down-feed screws rotate in opposite directions, and drive nut pointer to move up and down.The revolution of depth indicator leading screw and elevator
The revolution of main shaft is directly proportional, and spindle revolutions are with hoisting container, and the position in well is corresponding, therefore realizes pointer position and carries
Liter container position is corresponding, completes to indicate the position functions of hoisting container.
Memorial archway type depth indicator principle is: the rotation of main shaft of hoister is passed to depth indicator by power transmission shaft, makes two
Root down-feed screw rotates in opposite directions, and drives nut pointer to move up and down.The revolution of depth indicator leading screw and lifting owner
The revolution of axle is directly proportional, and spindle revolutions are with hoisting container, and the position in well is corresponding, therefore realizes pointer position and lifting
Container position is corresponding, completes to indicate the position functions of hoisting container.
Hoisting container close to deceleration position when, nut touches signal tie rod, makes bell send the sound, reminds driver to slow down.With
When, switch equipped with retarding travel under position-arresting disk, when reaching deceleration position, make elevator enter moderating process.When there is pulleying, spiral shell
Female bruising pulleying limit switch, carries out safety arrestment.If in running, because hoisting rope produces and sliding and wriggle, lead to
There is deviation it is possible to there is operation error in indicator for displaying and hoisting container position, cause accident.
Utility model content
The purpose of this utility model is to provide a kind of elevator memorial archway depth indicator, solves mechanical stroke switch, empty
Dynamic stroke is excessive, and it is unreliable to control, and there is the technical problem of potential safety hazard.
For solving the above problems, this utility model provides a kind of elevator memorial archway depth indicator, including photoswitch
Sq1, sq2, relay k1, k2, and plc pulleying input point x1, x2, pulleying display lamp m1, m2；
Mesh power supply p1, p2 are 24v power supply；
It is sequentially connected in series photoswitch normally opened contact sqk-1 and relay k1 between the both positive and negative polarity of 24v power supply；
On another branch road between the both positive and negative polarity of 24v power supply, it is sequentially connected in series the normally opened contact k1-1 of relay k1 and pulleying refers to
Show lamp m1；A node is selected, the negative pole of this node and 24v power supply between the normally opened contact k1-1 of relay k1 and pulleying display lamp m1
Between connect plc pulleying input point x1；
It is sequentially connected in series photoswitch normally opened contact sqk-2 and relay k2 between the both positive and negative polarity of 24v power supply；
On another branch road between the both positive and negative polarity of 24v power supply, it is sequentially connected in series the normally opened contact k2-1 of relay k2 and pulleying refers to
Show lamp m2；A node is selected, the negative pole of this node and 24v power supply between the normally opened contact k2-1 of relay k2 and pulleying display lamp m2
Between connect plc pulleying input point x2.
The elevator memorial archway depth indicator that this utility model provides, structure is simple, easy for installation, is easy to keep in repair, action
Sensitive reliability, no lost motion stroke, thus improve elevator operating safety factor.
Below in conjunction with the accompanying drawings elevator memorial archway depth indicator of the present utility model and its control method are made furtherly
Bright.
Brief description
Fig. 1 is the circuit connection diagram of elevator memorial archway depth indicator of the present utility model.
Specific embodiment
The present embodiment includes；Including photoswitch sq1, sq2, relay k1, k2, and plc pulleying input point x1, x2, mistake
Volume display lamp m1, m2；
Mesh power supply p1, p2 are 24v power supply.
As shown in figure 1, being sequentially connected in series photoswitch normally opened contact sqk-1 and relay k1 between the both positive and negative polarity of 24v power supply；
On another branch road between the both positive and negative polarity of 24v power supply, it is sequentially connected in series the normally opened contact k1-1 of relay k1 and pulleying refers to
Show lamp m1；A node is selected, the negative pole of this node and 24v power supply between the normally opened contact k1-1 of relay k1 and pulleying display lamp m1
Between connect plc pulleying input point x1；
It is sequentially connected in series photoswitch normally opened contact sqk-2 and relay k2 between the both positive and negative polarity of 24v power supply；
On another branch road between the both positive and negative polarity of 24v power supply, it is sequentially connected in series the normally opened contact k2-1 of relay k2 and pulleying refers to
Show lamp m2；A node is selected, the negative pole of this node and 24v power supply between the normally opened contact k2-1 of relay k2 and pulleying display lamp m2
