Mother is substituted by split pin 9, and knuckle 103 is equipped between the horizontal groove 102, perpendicular grooves 101 on driven pedestal 1B, convenient
Limit shaft 6 when active rotation column 2B is rotated in rotary force under the action of mark groove, and be caught in another groove.In this way,
Active rotation column 2A only need to be rotated, the folding operation of guardrail can be completed, it is convenient and efficient.
Active telescopic column is identical as driven telescopic column structure.Telescopic column 3 is fixedly connected with spring piece bracket 11, spring
Spring leaf 12 is set on plate rack, and an elastic button 10 is respectively set in the both ends of spring leaf 12, and the upper and lower side of Rotary cloumn 2 is set
Set one group of button card hole 201, telescopic column 3 is inserted into Rotary cloumn 2 and is simultaneously slidably connected therewith, when telescopic column 3 reach longest or
Most in short-term, elastic button 10 is caught in button card hole 201 and protrudes outward from button card hole 201.
Two telescopic columns 3 can slide up and down in active rotation column 2A and driven Rotary cloumn 2B respectively, work as cunning
When moving certain altitude, elastic button 10 is popped up from the button card hole 201 reserved on active rotation column 2A automatically, to flexible
The sliding of column 3 is limited.In this way, need to only press elastic button 10, guardrail height can be adjusted, it is convenient and efficient.
Meanwhile before guardrail folding, first column is shunk, so that the utility model can be adapted for most carriage rule
Lattice have general applicability.
It is fixed by crossbeam 4 between active rotation column 2A and driven Rotary cloumn 2B, between two telescopic columns 3
Connection, crossbeam 4 are U-shaped groove structure, and crossbeam 4 not only increases guardrail intensity, while also moving synchronously foundation for two heel posts
Bridge.
Vertical contact switch 13 is set on pedestal 1 and Rotary cloumn 2, and vertical contact switch 13 is including Switch main body and vertically
Contact, when the two contacts, contact switch can be just closed, and vertical contact mounting plate 17 is arranged in the back side of specifically driven pedestal 1B,
Vertical contact is set on vertical contact mounting plate 17, vertical contact Switch main body is arranged in the soffit of driven Rotary cloumn 2B,
When driven Rotary cloumn 2B in vertical state when, vertical contact trigger vertical contact Switch main body, vertical contact switch 13 closure.
Water-level contact switch 14 is set on pedestal 1 and Rotary cloumn 2, water-level contact switch 14 it is same including Switch main body with
Water-level contact, the front of specifically active pedestal 1A are arranged water-level contact mounting plate 16, water are arranged on water-level contact mounting plate 16
Flat contact, the front setting water-level contact Switch main body that places an order of active rotation column 2A, when active rotation column 2A is horizontal
When state, water-level contact triggers water-level contact Switch main body, and water-level contact switch 14 is closed.
Flexible contact switch 15 is set on Rotary cloumn 2 and telescopic column 3, the contact switch 15 that stretches include Switch main body and
Flexible contact is arranged flexible contact mounting plate 19 on specifically active rotation column 2A, is arranged on flexible contact mounting plate 19 and stretches
Contracting contact switch ontology, flexible contact is arranged in the lower end of telescopic column 3 corresponding with active rotation column 2A, when telescopic column 3
When reaching longest, flexible contact switch ontology is triggered in contact of stretching, and the contact switch 15 that stretches is closed.
The utility model shares three auxiliary contacts switch, and when guardrail is in extreme higher position, water-level contact switch 14 is disconnected, and hangs down
Straight contact switch 13 and flexible contact switch 15 are closed, and only car top overhauling are allowed to run at this time；When guardrail is shunk and is in folding
When horizontal position, water-level contact switch 14 is closed, and vertical contact switch 13 and flexible contact switch 15 disconnect, and only allows sedan-chair at this time
Compartment operates normally；Remaining situation, carriage cannot be run.
Specific situation is as follows:
When carriage operates normally, car top guard is as shown in Fig. 2, in contraction fold flat state.Water-level contact at this time
Switch 14 is closed, and vertical contact switch and flexible contact switch disconnect, and elevator can operate normally.
When needs are in car top overhauling, release wing nut will pull out, then in the horizontal groove 102 of 6 pedestal of limit shaft
Active rotation column 2A is rotated to plumbness, and limit shaft 6 is caught in the vertical recessed of pedestal automatically under spring force at this time
Slot 101 guarantees the vertical of fence upright；Then the elastic button 10 on telescopic vertical 3 is pressed, and promotes telescopic column 3 until bullet
Property button 10 from button card hole 201 pop up.Water-level contact switch 14 disconnects at this time, vertical contact switch 13 and flexible contact switch
15 closures, elevator can be with inspection travel.
Do not carried out after car top guard is shunk it is horizontal positioned or be horizontally arranged it is not in place, at this point, water-level contact switch 14
It disconnects, the contact switch 15 that stretches disconnects, and elevator is not normally functioning or inspection travel.
When car top guard is not contracted, and it is horizontally arranged not in place, at this point, water-level contact switch 14 disconnects, vertical contact is opened
It closes 13 to disconnect, elevator is not normally functioning or inspection travel.
When car top area is enough, car top guard is not shunk, i.e., horizontal folding is in place, at this point, water-level contact is opened
14 closures are closed, theoretically elevator can also operate normally, and have no effect on elevator safety performance.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
