Problems solved by technology

[0003] However, when there are soil fetching and digging operations on the side of the foundation pit or on the trestle bridge, the height of the fixed-height railings will hinder the normal use of mechanical equipment, often resulting in the removal of the installed railings, resulting in the lack of protective measures for this part , high-altitude border security risks are greatly increased

Embodiment 2

[0051] see Figure 10 , the difference between this embodiment and Embodiment 1 is:

[0052] The folding mechanism includes a middle cross bar 34 and several connecting rods 32. The middle cross bar 34 is located between the upper rail 31 of the movable guardrail and the fixed guardrail 2, and between the upper rail 31 of the movable guardrail and the middle cross bar 34. And between the fixed guardrail 2 and the middle cross bar 34, some parallel connecting rods 32 are respectively provided with in a hinged manner. The plumb line forms an isosceles triangle or is collinear with the plumb line.

[0053] And the structure of the guardrail height locking mechanism 4 is different from that of Embodiment 1. Specifically, the guardrail height locking mechanism 4 includes bolts 41 and nuts 42. The fixed column 1 is provided with a vertical chute 11, and the movable guardrail is provided with a vertical chute. The gear 31 is provided with a through hole for the bolt 41 rod of the b...

Embodiment 3

[0058] see Figure 11 , the difference between this embodiment and embodiment two is:

[0059] The folding mechanism includes a middle cross bar 34 and several rhombic connecting components, the middle cross bar 34 is located between the upper rail 31 of the movable guardrail and the fixed guardrail 2, and the upper rail 31 of the movable guardrail and the middle cross bar 34 And between the fixed guardrail 2 and the middle cross bar 34, several rhombic connecting assemblies are respectively arranged in a hinged manner, and the rhomboid connecting assemblies are formed by four connecting rods 32 end-to-end hinged. In this way, the use of the middle cross bar 34 can be reduced, and the construction cost can be reduced.

Embodiment 4

[0061] see Figure 12 , the difference between the present embodiment and the third embodiment is:

[0062] Described folding mechanism comprises several connecting assemblies, and described connecting assembly comprises by six connecting rods 32, and six connecting rods 32 are positioned at the vertical plane that movable guardrail upper shelf 31 and fixed column 1 constitute, and wherein four connecting rods 32 head and tail Hinged to form a rhombus connector, one end of the other two connecting rods 32 is respectively hinged with the upper end or lower end of the rhombus connector, and the other end is respectively hinged with the upper rail 31 of the movable guardrail or the fixed guardrail, and several connecting assemblies are arranged horizontally. The rhombus connectors of adjacent connection group assemblies are hinged at butt vertices. The strength of the upper rail 31 of the movable guardrail of this embodiment is higher than that of Embodiment 3, and the stability...

Abstract

The invention provides a folding type safety guardrail device. A protective guardrail arranged between adjacent fixed stand columns and a guardrail height locking mechanism are adopted, wherein the protective guardrail comprises a fixed guardrail body and a movable guardrail body; the movable guardrail body is arranged above the fixed guardrail body; the height of the movable guardrail body can beadjusted according to needs, and therefore soil taking; soil digging and other work can be conveniently carried out on the edge of a foundation pit and a trestle; the guardrail-free edge working state is effectively avoided; and the edge working safety risk is reduced. In addition, when a folding mechanism is completely folded, the movable guardrail body can cover the folding mechanism, the folding mechanism can be hidden and protected, and reliable running of the folding mechanism is guaranteed. Meanwhile, the top rigidity of the folding type safety guardrail device can be effectively enhanced, and deformation damage generated when equipment collides with the folding type safety guardrail device is reduced.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a folding safety guardrail device. Background technique [0002] The protective railings on the edge of the foundation pit at the construction site are generally erected with steel pipe fasteners, and those with higher civilized construction standards adopt stereotyped products. The height of the railings is about 1.2m-1.8m. use. [0003] However, when there are soil fetching and digging operations on the side of the foundation pit or on the trestle bridge, the height of the fixed-height railings will hinder the normal use of mechanical equipment, often resulting in the removal of the installed railings, resulting in the lack of protective measures for this part , The risk of high-altitude border security has greatly increased. According to incomplete statistics, safety accidents caused by high-altitude edge accounted for more than 50% of the national construction safety accide...
