Multiple pin holes 11131 are located at the different height of the column 1113, and the pin hole 11131 coordinates described
Bolt 116 controls the collapsing length of the movable straight tube 1111, so as to control the height of the Telescopic guardrail body 11.In this reality
It applies in example, when the bottom of the movable straight tube 1111 reaches the minimum pin hole 11131, the Telescopic guardrail body 11
Height meet installation national standard set when guardrail handrail outer rim to well enclosure level free distance no more than 0.85 meter when, help
Hand height is no less than 0.70 meter of guardrail height requirement；When the bottom of the movable straight tube 1111 reaches the highest bolt
During hole 11131, the height satisfaction installation national standard setting of the Telescopic guardrail body 11 works as guardrail handrail outer rim to well enclosure water
When flat free distance is more than 0.85 meter, handrail height is no less than 1.10 meters of guardrail height requirement.
The safety caging device 13 includes housing 131, switch module 133, connector 135, the idler wheel of tool receiving space
137 and alarm 139.The housing 131 is fixedly connected on the column 1113, and position is higher than the fixed transverse slat 114, institute
Switch module 133 is stated to be contained in the housing 131, the connector 135 respectively with the housing 131 and the idler wheel 137
Flexible connection, the idler wheel 137 are rolled along the groove 11111, and the alarm 139 is electrically connected with the switch module 133.
The switch module 133 includes fixing piece 1331, elastic element 1333, the first contact switch 1335 and the second contact
Switch 1337, the fixing piece 1331 and second contact switch 1335 are fixedly connected respectively with the housing 131, the bullet
Property element 1333 both ends be fixedly connected respectively with the fixing piece 1331 and first contact switch 1335, described first touch
Point switch 1335 and second contact switch 1337 are serially connected with elevator controlling circuit and the alarm control loop respectively.
The connector 135 includes the top splenium 1351 extended from its end.In the present embodiment, the connector
135 can be using the flexible connection position of itself and the housing 131 as axis rotation.
The top splenium 1351 is used for the first contact switch 1335 described in top pressure.In the present embodiment, the top splenium
1351 described in top pressure during the first contact switch 1335, and first contact switch 1335 and second contact switch 1337 connect
It touches, elevator controlling circuit is connected with the alarm control loop.
The thickness of the idler wheel 137 is slightly smaller than the width of the groove 11111, so that the idler wheel 137 can be described
It is rolled around in groove 11111.In the present embodiment, the idler wheel 137 can be with its active connection part with the connector 135
Position is axis rotation；And the idler wheel 137 is when being located at the first groove 11111A, the top splenium of the connector 135
1351 separate with first contact switch 1335, and elevator control circuit is connected, elevator normal operation；The idler wheel 137 is located at
During the second groove 11111B, the first contact switch 1335 described in 1351 top pressure of the top splenium of the connector 135, electricity
Terraced control circuit disconnects, and elevator is forbidden running, so as to ensure the safety of maintenance personal.
The alarm 139 is switched with control.In the present embodiment, when overhauling elevator, control switch is opened, if inspection
First contact switch 1335 is surprisingly connected with second contact switch 1337 during repairing, and the alarm 139 carries out
Alarm；When elevator does not overhaul, control switch is closed, first contact switch 1335 and second contact switch
1337 connection, elevator normal operation and the alarm 139 does not work.
The operating mode of the safety caging device 13 includes powered-on mode and power-down mode.
Under powered-on mode, the bolt 116 is extracted from the pin hole 11131, and passes through rope suspensions in described solid
Determine transverse slat 114, the telescopic column 111 is in fully collapsed condition, i.e., described movable straight tube 1111 reaches by the column
1113 maximum presets being arranged are arranged length, at this point, the height of the Telescopic guardrail body 11 is minimum, and meet hoistway top layer height
The requirement of degree.Meanwhile the idler wheel 137 is rolled back into the first groove 11111A, the idler wheel 137 drives the connector
135 is close to the movable straight tube 1111, so that the top splenium 1351 is separated with first contact switch 1335, it is described
First contact switch 1335 sets back under elastic element elastic force effect, at this point, 1335 He of the first contact switch
Second contact switch 1337 contacts, i.e., described switch module 133 is in releasing orientation, and elevator control circuit is connected, elevator
Normal operation.
Under power-down mode, the movable straight tube 1111 of the telescopic column 111 extends, when the movable straight tube 1111
Bottom when reaching 11131 position of pin hole, the bolt 116 is inserted into the pin hole 11131, so that described flexible
Guardrail body 11 meets the guardrail height requirement that installation national standard is set.Meanwhile the idler wheel 137 is from the first groove 11111A
Into the second groove 11111B, the idler wheel 137 drives the connector 135 to be moved away from the movable straight tube 1111,
So that the first contact switch 1335 described in 1351 top pressure of the top splenium of the connector 135, and then make described first to touch
Point switch 1335 and second contact switch 1337 separate, at this point, elevator control circuit disconnects, elevator is forbidden running, so as to
Ensure the safety of maintenance personal.In the present embodiment, the length of the Telescopic guardrail body 11 can be inserted into according to the bolt 116
The pin hole 11131 height adjust, so as to meet the needs of different user；During overhauling elevator, the alarm
Device 139 surprisingly connects elevator control circuit carry out alarm, so as to improve the reliability of the safety caging device 13.
After maintenance work, powered-on mode restarting.
