Description

Technical Field

[0001] The utility model relates to the technical field of bridge protection equipment, in particular to an anti-collision facility with an air bag. Background Art

[0002] With the rapid development of the national economy, more and more bridges are being built on major sea rivers, and they are getting bigger and bigger, making the original waterways smaller and smaller. In addition, the sailing ships are easily affected by the external environment, which can cause the ships to lose control and hit the bridges. In serious cases, the bridges may be irreversibly damaged, causing significant economic losses. Therefore, taking effective measures to prevent ships from hitting bridges is a very important part of bridge construction.

[0003] At present, most bridge anti-collision measures are to install bridge anti-collision facilities around the bridge to achieve the purpose of protecting the bridge. For example, Chinese patent publication number CN103741647B discloses a bridge anti-collision device, including an anti-collision energy dissipation ring and a slide rail mechanism arranged around the bridge pier. The slide rail mechanism includes a plurality of guide energy dissipation columns fixedly arranged between the anti-collision energy dissipation ring and the bridge pier and fixedly connected to the anti-collision energy dissipation ring. The axis of the guide energy dissipation column is parallel to the axis of the bridge pier. The energy dissipation unit includes a shell and a composite energy-absorbing material filled in the shell.

[0004] In the prior art, the installation of such bridge anti-collision facilities usually requires pre-assembly on the shore. However, due to the interference of external factors such as water flow and wind in rivers and seas, the floating state of water flow often changes greatly, such as Figure 1 As shown, the anti-collision facilities will be severely tilted during pre-assembly and final assembly. The flange surface A of each anti-collision facility will fall downward due to gravity, and the flange interface A of the two adjacent anti-collision facilities cannot remain horizontal and cannot be aligned due to the change in floating state, which greatly increases the difficulty and cost of pre-assembly construction. Utility Model Content

[0005] The utility model aims to overcome the defects of the prior art and provides an anti-collision facility with an air bag.

[0006] In order to achieve the above and other purposes, the utility model is implemented by the following technical solutions: providing an anti-collision facility with an airbag, characterized in that it includes an anti-collision ring and an airbag installed on the anti-collision ring. The airbag is used to maintain the balance of the anti-collision ring so that the anti-collision ring will not tilt.

[0007] In one embodiment, an inflation port is provided on the airbag for inflating the airbag, thereby reducing the construction difficulty of the anti-collision facility and improving the installation efficiency of the anti-collision facility.

[0008] In one embodiment, the inflation port is arranged on the lower end surface of the airbag.

[0009] In one embodiment, the anti-collision facility further comprises a mounting bracket, wherein the mounting bracket is mounted on the anti-collision ring, and the airbag is mounted on the lower end surface of the anti-collision ring through the mounting bracket.

[0010] In one embodiment, a mounting buckle is provided on the mounting bracket, a mounting cable is connected to the airbag, and the airbag is connected to the mounting buckle via the mounting cable.

[0011] In one embodiment, the mounting bracket includes a shaft sleeve and a column, the column is inserted into the shaft sleeve, and the mounting buckle is arranged on the column.

[0012] In one embodiment, a first pin hole is formed on the sleeve, and a second pin hole is formed on the column. After the airbag is inflated, the first pin hole and the second pin hole are matched and connected. The volume of the airbag changes during inflation and deflation, driving the column to move up and down in the sleeve. When the column moves to a specified position, the first pin hole and the second pin hole are aligned and locked by a pin connection.

[0013] In one embodiment, a plurality of the mounting buckles are arranged on the column at equal intervals.

[0014] In one embodiment, the airbag is a sealed structure, and the outer surface of the airbag is made of waterproof material.

[0015] In one embodiment, a plurality of the airbags are installed on the anti-collision ring. According to the size requirements of the anti-collision ring, a plurality of the airbags are arranged to improve the flexibility of use of the anti-collision facility.

[0016] To sum up, by arranging the airbag on the anti-collision ring, upward buoyancy can be applied to the anti-collision ring, so that the anti-collision ring can maintain a balanced state without tilting even when the buoyancy of the water flow changes greatly, which greatly reduces the installation difficulty and cost, and at the same time protects the anti-collision ring to a certain extent.

[0023] See also Figures 2 to 6 . The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below. In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0024] Please combine Figures 2 to 6 The utility model provides an anti-collision facility 1 with an airbag, comprising an anti-collision ring 11, a mounting bracket 12 and an airbag 13. The airbag 13 is installed on the anti-collision ring 11 through the mounting bracket 12 to balance the anti-collision ring 11 so that the anti-collision ring 11 maintains a balanced state in the water flow.

[0025] Please combine Figure 2 and Figure 3 In the first embodiment, the mounting bracket 12 is arranged on the anti-collision ring 11 to mount the airbag 13. The airbag 13 can be mounted at a position close to the flange surface 113 of the anti-collision ring 11 to apply an upward buoyancy to the falling end of the anti-collision ring 11. Of course, the mounting position of the airbag 13 can be adjusted according to actual conditions.

[0026] The mounting bracket 12 includes a sleeve 121 and a column 122. The sleeve 121 is mounted on the outer ring end face 111 and the inner ring end face 112 of the anti-collision ring 11. The column 122 is fixedly mounted in the sleeve 121. The column 122 is also provided with a plurality of mounting buckles 1221 for mounting and fixing the airbag 13. In this embodiment, the plurality of mounting buckles 1221 can be arranged on the column 122 at equal intervals; in other embodiments, the plurality of mounting buckles 1221 can also be arranged on the column 122 at non-equal intervals.

[0027] The airbag 13 is a sealed structure, and the outer surface of the airbag 13 is made of waterproof material. The end surface of the airbag 13 in contact with the column 122 is provided with a mounting cable 131, one end of the mounting cable 131 is connected to the airbag 13, and the other end is installed on the mounting buckle 1221. An inflation port 132 is also provided on the lower end surface of the airbag 13. Before installation, the airbag 13 is inflated through the inflation port 132; when the anti-collision facility 1 reaches the designated position, the airbag 13 is deflated through the inflation port 132.

[0028] In the first embodiment, a group of the mounting brackets 12 are installed on the anti-collision ring 11, and the group of the mounting brackets 12 includes eight sleeves 121 and four columns 122, and the four columns 122 are respectively used to fix the four corners of the airbag 13. Two columns 122 are symmetrically installed on the outer end surface 111 and the inner end surface 112; each column 122 is installed by two sleeves 121 arranged up and down. One airbag 13 is installed on the lower end surface of the anti-collision ring 11 through four mounting cables 131, and the four mounting cables 131 are respectively connected to the mounting buckles 1221 on the four columns 122. Of course, in some other embodiments, multiple airbags 13 may be installed on the lower end surface of the anti-collision ring 11 through the columns 122.

[0029] Please combine Figure 4 and Figure 5 In the second embodiment, the column 122 can move up and down in the sleeve 121. Preferably, the outer diameter of the column 122 is the same as the inner diameter of the sleeve 121, so that the column 122 will not shake when it is inserted into the sleeve 121. The sleeve 121 is provided with a plurality of first pin holes 1211, and the column 122 is provided with a plurality of second pin holes 1222, and the first pin holes 1211 and the second pin holes 1222 match. After the airbag 13 is inflated, the volume and height of the airbag 13 increase, thereby driving the column 122 to move in the sleeve 121. After moving to a fixed position, the first pin hole 1211 and the second pin hole 1222 are aligned, and the second pin hole 1222 and the first pin hole 1211 are connected and locked by a pin (not shown in the figure). In this embodiment, only one mounting buckle 1221 may be provided on the column 122.

[0030] like Figure 6As shown, when the size of the anti-collision ring 11 is large, multiple groups of mounting brackets 12 and multiple airbags 13 can be installed on the anti-collision ring 11. In the third embodiment, two groups of mounting brackets 12 are installed on the anti-collision ring 11, and two airbags 13 are installed on each group of mounting brackets 12. Of course, in some other embodiments, the number of the mounting brackets 12 and the airbags 13 can be appropriately adjusted according to actual conditions.

[0031] Please combine again Figures 2 to 6 When installing the anti-collision facility 1, the anti-collision facility 1 is placed in a river or sea. Due to the change in the buoyancy of the water flow, the anti-collision ring 11 is tilted, and the airbag 13 corresponding to the position where the anti-collision ring 11 sinks downward is inflated, so that the airbag 13 applies an upward buoyancy to the position where the anti-collision ring 11 sinks downward, thereby keeping the anti-collision ring 11 balanced and horizontal; the balanced anti-collision facility 1 is transported to the vicinity of the destination bridge for assembly, and the anti-collision ring 11 is deflated after assembly.

[0032] In summary, by arranging the airbag 13 on the anti-collision ring 11, an upward buoyancy can be applied to the anti-collision ring 11, so that the anti-collision ring 11 can maintain a balanced state without tilting even when the floating state of the water flow changes greatly, which greatly reduces the installation difficulty and installation cost, and at the same time protects the anti-collision ring 11 to a certain extent.
