Embodiment 1

[0039] Such as figure 1 A built-in airbag-type anti-collision device based on prestressed steel bars is shown, including an outer steel wall plate 1, a lining steel wall plate 3 located inside the outer steel wall plate 1, and a bottom end anchored at the bottom of the outer steel wall plate 1. A plurality of prestressed tendons 10 and buckled steel plates 12 fastened on the outer side of the middle and upper part of the outer steel wall plate 1 and the lower part is stretched through the plurality of prestressed tendons 10 . An anti-collision cavity is formed between the outer steel wall plate 1 and the inner steel wall plate 3, a layer of counterweight cushion 5 is arranged at the bottom of the anti-collision cavity, and the anti-collision cushion on the top of the counterweight cushion 5 The collision cavity is filled with multiple rubber airbags 7, and the multiple rubber airbags 7 are arranged on the same plane. The lined steel wall plate 3 is located outside the device ...

Embodiment 2

[0066] In this example, if figure 2 , image 3 As shown, the difference from Example 1 is that: the protection device to be protected is an anti-collision column 9; the lined steel wall plate 3 arranged on the outside of the anti-collision column 9 is an annular steel plate 1 bent from a straight steel plate 2, The outer steel wall plate 1 positioned at the outer side of the first annular steel plate is an annular steel plate two bent by the second circular arc steel plate, and the cross section of the second circular arc steel plate is arc-shaped; The buckle steel plate 12 on the outer side of the middle and upper part of the arc steel plate one is an annular steel plate three bent by the arc steel plate four, and the cross section of the arc steel plate four is arc-shaped; On the outside of the striker 9, the second ring-shaped steel plate is set on the outer side of the first ring-shaped steel plate, and the third ring-shaped steel plate is set on the outer side of the mi...

Abstract

The invention discloses a built-in air bag type anti-collision device based on prestressed reinforcement. The device comprises an outer steel wall plate, a lining steel wall plate, multiple prestressed tendons and an up-buckling steel plate, wherein the bottom ends of the prestressed tendons are anchored at the bottom of the outer steel wall plate; the up-buckling steel plate is buckled on the outer side of the outer steel wall plate, and the lower part of the up-buckling steel plate is tensioned through multiple prestressed tendons; an anti-collision cavity is formed between the outer steel wall plate and the lining steel wall plate; a counter weight pad layer is arranged at the bottom of the anti-collision cavity; multiple rubber air bags are filled in the anti-collision cavity at the upper part of the counter weight pad layer and arranged on the same plane; the lining steel wall plate is located on the outer side of a device needing protection; an energy absorption pad layer is arranged between the lining steel wall plate and the device needing protection; and the upper end part of the up-buckling steel plate is fixed at the top of the energy absorption pad layer. The device disclosed by the invention has the advantages of reasonable structure design, low investment cost, long service life and good using effect, is convenient to construct, and can effectively overcome the shortcomings of higher investment cost, shorter service life, poor anti-collision effect and the like of the anti-collision facility of the existing traffic tool.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to a built-in airbag type anti-collision device based on prestressed steel bars. Background technique [0002] Nowadays, in the process of construction of transportation facilities, the requirements for traffic safety facilities are becoming more and more stringent, and they are more widely used in daily life, with various types and styles. Among them, anti-collision facilities for vehicles, ships and other vehicles are extremely important safety protection facilities among many types of traffic safety facilities. However, most of the anti-collision facilities used for vehicles can only withstand a single impact, so frequent repairs or replacements are required, which is time-consuming and labor-intensive, and the input cost is high; and if the repairs or replacements are not timely, traffic The safety protection effect is out of the question. In addition, the existing anti-collision fa...
