Abstract
The utility model relates to a foldable bridge frame. The foldable bridge frame comprises the following components: a bridge frame body (3), a first bridge frame body (1) and a second bridge frame body (4) which are arranged at two sides of the bridge frame body (3). The first bridge frame body (1) and the second bridge frame body (4) are hinged with the bridge frame body (3). When the first bridge frame body (1) rotates to the side of the bridge frame body (3), the first bridge frame body can be accommodated in a space which is formed when the second bridge frame body (4) is rotated to the side of the bridge frame body (3). According to the foldable bridge frame, the bridge frame can be folded through an ingenious structure form. Through reasonably arranging hinging points, no interference is generated in folding, and the bridge frame is minimized maximally in a transportation process. Compared with a traditional bridge frame, the foldable bridge frame has the advantages of greatly reduced space occupation and reduced transportation cost.
Description
Technical field
The utility model relates to a kind of collapsible crane span structure, belongs to cable mounting technique field.
Background technique
Crane span structure is the support of a support and payout.Crane span structure is used on engineering very general, as long as cable laying will be used crane span structure, more because of the crane span structure of using,, therefore how to reduce the volume of crane span structure in the process of transportation as far as possible,, to reduce cost of transportation, just become an important research direction.
The model utility content
The utility model is for above-mentioned defect, purpose be to provide a kind of simple in structure, can realize folding, to reach the collapsible crane span structure that reduces cost of transportation.
The technical solution adopted in the utility model is for this reason: the utility model comprises crane span structure body (3) and is arranged on crane span structure body one (1) and the crane span structure body two (4) of crane span structure body (3) both sides, and described crane span structure body one (1), crane span structure body two (4) are hinged on crane span structure body (3); Within the space that forms in the time of being rotated to crane span structure body (3) side by accommodating and crane span structure body two (4) when described crane span structure body one (1) rotates to crane span structure body (3) side.
Described crane span structure integral body is trapezoidal, within the articulating point (2) of described crane span structure body one (1) and crane span structure body (3) is arranged on the articulating point (2) of crane span structure body two (4) and crane span structure body (3).
The utility model has the advantages that: the utility model passes through structural type cleverly, can crane span structure is folding, reasonably arrange by articulating point, make while folding and can not produce interference phenomenon, as much as possible in transportation process with the crane span structure miniaturization, compare traditional crane span structure, it takes up room and greatly reduces, and has reduced cost of transportation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that crane span structure body one, 2 is that articulating point, 3 is that crane span structure body, 4 is crane span structure body two.
Embodiment
The utility model comprises crane span structure body 3 and the crane span structure body 1 and the crane span structure body 24 that are arranged on crane span structure body both sides, and described crane span structure body 1, crane span structure body 24 are hinged on crane span structure body 3; Within the space that can be formed when crane span structure body 3 sides are rotated by accommodating and crane span structure body 24 when described crane span structure body 1 rotates to crane span structure body 3 sides.
Described crane span structure integral body is trapezoidal, within the articulating point 2 of described crane span structure body 1 and crane span structure body 3 is arranged on the articulating point 2 of crane span structure body 24 and crane span structure body 3.
Working procedure of the present utility model is, at first crane span structure body 1 rotated to crane span structure body 3 when folding, after rotateing in place, then crane span structure body 24 rotated to crane span structure body 3, thereby forms folding structure; Expansion, according to getting final product of the reverse row of above-mentioned steps.
Claims (1)
