Embodiment
Fig. 1~3 used below, folding guardrail device of the present invention is described in detail.
Schematic diagrames of the Fig. 1 for folding guardrail device of the invention in a state of use.Fig. 2 is folding of the invention
The schematic diagram of formula protective guard device in a folded configuration.As shown in Figure 1 and Figure 2, folding guardrail of the present embodiment
Device 1 includes：Baseplate part 2, the first guardrail 3A, the second guardrail 3B, support 5, first connecting portion 6A, second connecting portion 6B, pivoted arm
7.In addition, folding guardrail device 1 also includes additional guardrail 9 and for folding guardrail device 1 to be fixed on into engineering
Supporting leg 4 in mechanical car.
Baseplate part 2 is made up of the net-shaped metal plate of rectangle, more specifically for be to be made up of stainless steel crocodile plate.By this
Sample, can also play anti-skidding, corrosion-resistant effect in rugged environment.It can certainly be selected according to specific working site
Other materials constitute baseplate part 2.Under the use state of folding guardrail device 1, the baseplate part 2 is located at horizontal direction energy
Enough bear the weight of staff or working equipment.Further, trunnion axis 21 is provided with the one end of baseplate part 2, its with it is rear
State the axle sleeve 51 being arranged on support 5 to be hinged, enable above and below baseplate part 2 carries out centered on the axis of trunnion axis 21
Rotate.
Support 5 is formed as strip, and including：The axle sleeve 51 on the both ends of its length direction is arranged on, it is arranged on
On the one end (Fig. 1, Fig. 2 left part) of length direction and rotating shaft 52 that axis extends to vertical direction.Rotating shaft 52 and pivoted arm 7
One end be hinged, pivoted arm 7 is horizontally rotated centered on the axis of rotating shaft 52.
Further, vertically extended is fixedly installed on the other end (Fig. 1, Fig. 2 right part) of support 5
One connecting portion 6A.First connecting portion 6A is formed as cylindric, and the sleeve vertically extended is provided with its top ends
61A.The aftermentioned vertical pivot 32A being arranged on the first guardrail 3A is inserted in sleeve 61A, enables the first guardrail 3A with vertical pivot 32A
Axis centered on horizontally rotate.
In addition, being fixedly installed the second connecting portion 6B vertically extended on the other end of pivoted arm 7.Second connects
Socket part 6B is again formed as cylindric, and is also equipped with its top ends the sleeve 61B that vertically extends.In sleeve 61B
The middle aftermentioned vertical pivot 32B being arranged on the second guardrail 3B of insertion, enables the second guardrail 3B to enter centered on vertical pivot 32B axis
Row horizontally rotates.
In addition, two supporting legs 4 are fixedly installed on support 5.And the supporting leg 4 is set using the cantilever beam of high strength square steel
Meter, with higher resistance to torsion.
First guardrail 3A, the second guardrail 3B include respectively：Guardrail framework 31A, 31B and and guardrail with safeguard function
Vertical pivot 32A, 32B that framework 31A, 31B is integrally formed and extended to vertical direction.Because using guardrail framework 31A, 31B,
The overall weight reduction production cost of folding guardrail device can be mitigated compared with using the guardrail of plate body.In addition, by
Vertical pivot 32A, vertical pivot 32B and sleeve 61A, sleeve 61B are hinged respectively in using inserted mode, therefore the first guardrail 3A, second
Guardrail 3B can be moved (flexible) along vertical pivot 32A, vertical pivot 32B axis direction respectively.
Fig. 3 is the partial schematic diagram in the folding guardrail device of the present invention.As shown in figure 3, making first using lock pin 8
Guardrail 3A can not be moved up and down (flexible) relative to first connecting portion 6A.Likewise, lock pin 8 can also be used to make the second guardrail 3B
It can not be moved up and down (flexible) relative to second connecting portion 6B.
In addition, folding guardrail device 1 is also included relative to adding that the first guardrail 3A, the second guardrail 3B can be dismounted
Guardrail 9.Further, additional guardrail 9 can be made up of on-deformable metal material or resin material or by yielding
Rope constitute.
As shown in figure 1, under the use state of folding guardrail device 1, baseplate part 2 is located at horizontal direction.By turning
The downside that the upper side of arm 7 is connected to baseplate part 2 makes the supporting substrate portion 2 of pivoted arm 7.By accordingly even when being not provided with other branch
Component is supportted, also baseplate part 2 can be made to be supported.With this, the structure of whole device is further simplify, makes whole device tighter
Gather, cost it is lower.Certainly, in order that support becomes more to consolidate, supporting substrate portion 2 in a state of use can also be set in addition
Support meanss.This support means can include：It is arranged on the rotating shaft on the other end of support 5 (Fig. 1, Fig. 2 right part)
And the pivoted arm with the shaft hinge.Although becoming complicated by relative in this support meanss structure, can balancedly it support
Baseplate part 2, makes support become more to consolidate.
Also under the use state of folding guardrail device 1, first connecting portion 6A and second connecting portion 6B is configured
The diagonal position of rectangle, the first guardrail 3A, the second guardrail 3B are abreast configured in the left and right sides of baseplate part 2.Also, first
Guardrail 3A, the second guardrail 3B are respectively relative to first connecting portion 6A, second connecting portion 6B and risen after (elongation) to certain altitude, make
Make this highly constant with lock pin 8.In addition, the two ends of additional guardrail 9 are arranged on the first guardrail 3A, the second guardrail 3B.With this,
The guardrail that three side sealing is closed can be formed by the first guardrail 3A with certain altitude, the second guardrail 3B and additional guardrail 9, can
Ensure the safety of staff.
As shown in Fig. 2 under the folded state of folding guardrail device 1, baseplate part 2 is located at vertical side after being rotated
To.On the one hand, by the one side and first connecting portion 6A abutting of baseplate part 2, baseplate part 2, which is limited, can not continue to turn clockwise
It is dynamic.On the other hand, the second connecting portion 6B and baseplate part 2 that are arranged on by rotating pivoted arm 7 to make on pivoted arm 7 another side are supported
Connect.That is first connecting portion 6A, second connecting portion 6B are connected to positioned at the two sides of the baseplate part 2 of vertical direction, the quilt of baseplate part 2 respectively
Clamped by first connecting portion 6A, second connecting portion 6B.Also, the first guardrail 3A, the second guardrail 3B are also connected to base at the same time
The two sides of plate portion 2.By the way that so, the densification of whole device can be accomplished.
It is released from also by lock pin 8, because the respective deadweight of the first guardrail 3A, the second guardrail 3B is respectively relative to first
The axis of connecting portion 6A, second connecting portion 6B along vertical pivot 32A, vertical pivot 32B moves down (contraction), even in folding guardrail
Under the folded state of device 1, the upper limb of baseplate part 2 is still located under described guardrail 3A, 3B upper limb.By so, relatively
In without the device for shrinking guardrail, the further densification of whole device can be accomplished.
In addition under the folded state of folding guardrail device 1, additional guardrail 9 is from the first guardrail 3A, the second guardrail 3B
On be removed.
