Detailed description of the invention
Below use Fig. 1 ~ 3, the folding guardrail device that the utility model relates to is described in detail.
Fig. 1 be folding guardrail device of the present utility model in a state of use schematic diagram.Fig. 2 be folding guardrail device of the present utility model in a folded configuration schematic diagram.As shown in Figure 1 and Figure 2, folding guardrail device 1 of the present embodiment comprises: baseplate part 2, the first guardrail 3A, the second guardrail 3B, support 5, the first connecting portion 6A, the second connecting portion 6B, pivoted arm 7.In addition, folding guardrail device 1 also comprises additional guardrail 9 and for folding guardrail device 1 being fixed on the supporting leg 4 on engineering machine vehicle.
Baseplate part 2 is made up of the net-shaped metal plate of rectangle, is more specifically to be made up of corrosion-resistant steel crocodile plate.By like this, even if anti-skidding, corrosion-proof effect also can be played in rugged environment.Other material can certainly be selected baseplate part 2 is formed according to concrete work-site.Under the using state of folding guardrail device 1, this baseplate part 2 is positioned at the weight that horizontal direction can bear staff or working equipment.Further, an end of baseplate part 2 is provided with horizontal shaft 21, itself and the aftermentioned axle sleeve 51 be arranged on support 5 carry out hinged, make baseplate part 2 can carry out upper and lower rotation centered by the axis of horizontal shaft 21.
Support 5 is formed as strip, and comprises: be arranged on the axle sleeve 51 on the both ends of its length direction, the rotating shaft 52 that the upper and axis in the end (left part of Fig. 1, Fig. 2) being arranged on its length direction extends to vertical direction.Rotating shaft 52 is hinged with an end of pivoted arm 7, and pivoted arm 7 can be horizontally rotated centered by the axis of rotating shaft 52.
Further, the other end (right part of Fig. 1, Fig. 2) of support 5 is fixedly installed the first connecting portion 6A vertically extended.First connecting portion 6A is formed as cylindric, and in its top ends, be provided with the sleeve 61A vertically extended.In sleeve 61A, insert the aftermentioned vertical pivot 32A be arranged on the first guardrail 3A, the first guardrail 3A is horizontally rotated centered by the axis of vertical pivot 32A.
In addition, the other end of pivoted arm 7 is fixedly installed the second connecting portion 6B vertically extended.Second connecting portion 6B is also formed as cylindric, and in its top ends, be also provided with the sleeve 61B vertically extended.In sleeve 61B, insert the aftermentioned vertical pivot 32B be arranged on the second guardrail 3B, the second guardrail 3B is horizontally rotated centered by the axis of vertical pivot 32B.
In addition, two supporting legs 4 are fixedly installed on support 5.And this supporting leg 4 adopts the Design of Cantilever Beam of high strength square steel, there is higher resistance to torsion.
First guardrail 3A, the second guardrail 3B comprise respectively: have safeguard function guardrail framework 31A, 31B and with guardrail framework 31A, 31B one-body molded and that extend to vertical direction vertical pivot 32A, 32B.Because adopt guardrail framework 31A, 31B, so the weight that can alleviate folding guardrail device entirety compared with adopting the guardrail of tabular body reduces productive costs.In addition, owing to adopting inserted mode respectively that vertical pivot 32A, vertical pivot 32B and sleeve 61A, sleeve 61B is hinged, therefore the first guardrail 3A, the second guardrail 3B can move (stretching) along the axis direction of vertical pivot 32A, vertical pivot 32B respectively.
Fig. 3 is the partial schematic diagram in folding guardrail device of the present utility model.As shown in Figure 3, use lock pin 8 that first guardrail 3A can not be moved up and down (stretching) relative to the first connecting portion 6A.Same, also can use lock pin 8 that second guardrail 3B can not be moved up and down (stretching) relative to the second connecting portion 6B.
In addition, also comprise can the additional guardrail 9 of dismounting relative to the first guardrail 3A, the second guardrail 3B for folding guardrail device 1.Further, additional guardrail 9 can be made up of on-deformable metallic material or resin material, also can be made up of yielding rope.
As shown in Figure 1, under the using state of folding guardrail device 1, baseplate part 2 is positioned at horizontal direction.The downside being connected to baseplate part 2 by the upper side of pivoted arm 7 makes pivoted arm 7 supporting substrate portion 2.Even if by not arranging other load-carrying element like this, baseplate part 2 also can be made to be supported.With this, further simplify the structure of whole device, make that whole device is compacter, cost is lower.Certainly, in order to make support become more firm, the bracing or strutting arrangement of using state lower support baseplate part 2 can be also arranged in addition.This bracing or strutting arrangement can comprise: be arranged on the rotating shaft on the other end (right part of Fig. 1, Fig. 2) of support 5 and the pivoted arm with this shaft hinge.By although this bracing or strutting arrangement structure becoming relatively complicated, can balancedly supporting substrate portion 2, make support become more firm.
Also have under the using state of folding guardrail device 1, the first connecting portion 6A and the second connecting portion 6B is configured in the diagonal position of rectangle, and the first guardrail 3A, the second guardrail 3B are configured in the left and right sides of baseplate part 2 abreast.Further, the first guardrail 3A, the second guardrail 3B relative to after the first connecting portion 6A, the second connecting portion 6B rising (elongation) to certain altitude, use lock pin 8 to make this highly constant respectively.In addition, the two ends of additional guardrail 9 are arranged on the first guardrail 3A, the second guardrail 3B.With this, can form by the first guardrail 3A, the second guardrail 3B and additional guardrail 9 with certain altitude the guardrail that three side sealing closes, the safety of staff can be guaranteed.
As shown in Figure 2, under the folded state of folding guardrail device 1, after baseplate part 2 is rotated, be positioned at vertical direction.On the one hand, by the one side of baseplate part 2 and abutting of the first connecting portion 6A, baseplate part 2 is limited can not be continued to rotate clockwise.On the other hand, by rotating pivoted arm 7, the second connecting portion 6B be arranged on pivoted arm 7 is abutted with the another side of baseplate part 2.Namely the first connecting portion 6A, the second connecting portion 6B are connected to the two sides of the baseplate part 2 being positioned at vertical direction respectively, and baseplate part 2 is clamped by the first connecting portion 6A, the second connecting portion 6B.Further, the first guardrail 3A, the second guardrail 3B are also connected to the two sides of baseplate part 2 at the same time.By like this, the densification of whole device can be accomplished.
Removed by lock pin 8 in addition, because the first guardrail 3A, the second guardrail 3B deadweight separately move down (contraction) along the axis of vertical pivot 32A, vertical pivot 32B relative to the first connecting portion 6A, the second connecting portion 6B respectively, even if under the folded state of folding guardrail device 1, the upper limb of baseplate part 2 is still positioned under the upper limb of described guardrail 3A, 3B.By like this, relative to the device not 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 removed from the first guardrail 3A, the second guardrail 3B.
