preferably, the bottom of fagging is arranged on permanent seat by axis of rotation, and the upper end of fagging is provided with the V-type groove of opening up setting, and when after locking piece locking, connecting portion is arranged in V-type groove.
preferably, when after locking piece locking, fagging outwards overturns around the shaft and is 30 ° with the angle that permanent seat is formed.
specifically implement and preferred aspect according to one of the present invention, carrying platform is rectangle, and locking piece has four, and is arranged on the corner of carrying platform.
concrete, locking piece is quick position presser feet.
specifically implement and preferred aspect according to of the present invention another, guardrail is also provided with many pilot bars, and pilot bar passes perpendicularly through carrying platform, and carrying platform can move relative to pilot bar.
due to the enforcement of above technical scheme, the present invention compared with prior art tool has the following advantages:
the present invention, by the relative motion of carrying platform and guardrail, realizes rising and the decline of guardrail, and can make fence enclosure in frame, reduces the volume of elevator, is convenient to movement and the transport of elevator, and meanwhile, structure of the present invention is simple, and it is convenient to implement, and cost is low.
Accompanying drawing explanation
below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described in detail.

fig. 2 is the schematic front view (guard bar lifting process) according to guardrail regulating mechanism of the present invention;
fig. 3 is the schematic front view (when elevator uses) according to guardrail regulating mechanism of the present invention;
wherein: 1, guardrail; 2, carrying platform; 3, pilot bar; 4, locking piece (quick position presser feet); 5, frame; 6, permanent seat; 7, fagging; 70, V-shaped groove; 8, connecting portion; 9, buckle hanging unit.
Detailed description of the invention
as shown in Figure 1 to Figure 3, according to the guardrail regulating mechanism of the double-mast formula elevator of the present embodiment, its guardrail 1 can be arranged on the periphery of carrying platform 2 up and down along vertical direction, concrete regulating mechanism comprise the bottom that is positioned at carrying platform 2 for the locking piece 4 locked relative with guardrail 1 for carrying platform 2, the permanent seat 6 be fixed on lift frame 5, can 0 ° ~ 90 ° faggings 7 be arranged on turningly on permanent seat 6.Wherein guardrail 1 moves up and down along pilot bar 3, and after locking piece 4 locks, guardrail 1 is relative with carrying platform 2 to be locked, and the bottom shelf of guardrail 1 is located on fagging 7; After locking piece 4 unlocks, fagging 7 draws in permanent seat 6, and guardrail 1 moves down, until cover in frame 5.
concrete, be provided with connecting portion 8 top in the bottom of guardrail 1 and be provided with buckle hanging unit 9, after locking piece 4 locks, connecting portion 8 is erected on the fagging 7 of upset outside permanent seat 6, after locking piece 4 unlocks, fagging 7 draws in permanent seat 6, and guardrail 1 moves down, buckle hanging unit 9 is hung on carrying platform 2, and guardrail 1 covers in frame 5.
concrete, the bottom of fagging 7 is arranged on permanent seat 6 by axis of rotation, and the upper end of fagging 7 is provided with the V-type groove 70 of opening up setting, after locking piece 4 locks, fagging 7 outwards overturns around the shaft and is 30 ° with the angle that permanent seat 6 is formed, and connecting portion 8 is arranged in V-type groove 70.
carrying platform 2 is rectangle, and locking piece 4 has four, and is arranged on the corner of carrying platform 2.Locking piece 4 in this example is quick position presser feet (very common, concrete structure does not describe in detail at this).
