Detailed Description

Example (b): a safety suspension bridge guardrail is shown in figure 1 and comprises a guardrail body 1 which is connected to the side surface of a bridge floor 4 and used for guaranteeing the safety of people on the bridge. During the use, connect guardrail body 1 in the both sides of suspension bridge deck 4, when having the visitor on the bridge, guardrail body 1 can provide the holding power for the visitor when the visitor has the tendency of empting.

As shown in fig. 1, the guardrail body 1 includes a plurality of vertical supports 11 fixedly connected to the bridge deck 4, and a plurality of folding protection mechanisms 2 are connected between each two vertical supports 11. The top parts of all the vertical brackets 11 positioned at the same side of the bridge deck 4 are fixedly connected with the suspension ropes 3 together. When the bridge deck 4 is bent and shaken due to pedestrians or wind power, the bottom support can rotate for a certain angle along with the bending of the bridge deck 4 in the longitudinal section, so that the guardrail body 1 can be stably connected with the bridge deck 4 all the time. The suspension ropes 3 can prevent the bridge deck 4 from bending too much, and have a certain supporting effect on the bridge deck 4.

As shown in fig. 1 and 2, the folding prevention mechanism 2 includes two first folding bars 21 rotatably connected to the two vertical supports 11, respectively. Every first folding rod 21 keeps away from the one end of vertical support 11 and all rotates and be connected with the folding pole 22 of second, and the equal level of the folding pole 22 of second sets up, and the folding pole 22 of second all is located first folding rod 21 and keeps away from bridge floor one side, and the folding pole 22 homoenergetic of second is at the cross section internal rotation. Folding spring 221 is fixedly connected to each second folding rod 22, one end of each folding spring 221, which is far away from the second folding rod 22, is fixedly connected to one side, which is close to the second folding rod 22, of the first folding rod 21, and the folding spring 221 can apply a force to the second folding rod 22, which moves towards the first folding rod 21. The ends of the two second folding rods 22 away from the vertical support 11 are connected with a support rod 23 in a co-rotating manner, and the support rod 23 can rotate in the cross section. The support bar 23, the second folding bar 22 and the first folding bar 21 are arranged in a zigzag shape. Can hit bracing piece 23 when the visitor emptys to the direction that is close to guardrail body 1, apply the power that the direction removed is emptyd to the visitor for bracing piece 23, bracing piece 23 can drive the rotation of second folding rod 22 to and drive first folding rod 21 and rotate, folding spring 221 can give second folding rod 22 one the power that draws close to first folding rod 21 this moment, thereby drive bracing piece 23 and apply the power that removes to 4 directions of bridge floor to the visitor, alleviate the trend that the visitor emptys, reduce the probability that the visitor turned out the guardrail.

As shown in fig. 2 and 3, a ball block of the universal joint 211 is fixedly connected to a position of the first folding rod 21 close to the vertical support 11, a rectangular shell of the universal joint 211 is fixedly connected to a position of the vertical support 11 corresponding to the first folding rod 21, and the first folding rod 21 and the vertical support 11 are rotatably connected through the universal joint 211. Connect vertical support 11 and first folding rod 21 through universal joint 211, can let first folding rod 21 homoenergetic rotate in level and vertical direction, make guardrail body 1 can rotate along with the bending degree of suspension bridge when the suspension bridge takes place to buckle, and then the guardrail can not damage when the guarantee suspension bridge takes place to buckle.

As shown in fig. 2 and 3, an elastic rubber layer 231 is fixedly connected to one side of the support rod 23 close to the bridge deck 4. When personnel hand bracing piece 23, the rubber layer 231 can effectively play skid-proof effect, reduces personnel and does not grab steady bracing piece 23 and lead to bracing piece 23 to take off hand's probability.

As shown in fig. 4 and 5, a hanging ring 31 is sleeved on the hanging rope 3, and a safety rope 32 is connected to the hanging ring 31. The hanging ring 31 is fixedly connected with a rope groove 310, and the safety rope 32 is inserted in the rope groove 310. A screw hole 311 is opened at one side of the rope groove 310, a bolt 321 is screwed into the screw hole 311, and the bolt 321 can pass through the screw hole 311 and abut against the safety rope 32. When the safety rope 32 needs to be fixed, the bolt 321 can be rotated to tightly abut against the safety rope 32, so that the safety rope 32 is fixed. Not only can ensure the stability of the connection of the two, but also can be conveniently replaced. The safety rope 32 is made of elastic material such as synthetic fiber, and a climbing buckle 322 is fixedly connected to one end of the safety rope 32 far away from the hanging ring 31. When the safety rope 32 is used, the climbing buckle 322 is hung on clothes or a belt of a person, and when the tourist tends to fall or fall, the safety rope 32 can apply traction force to the person to prevent the tourist from falling or falling. The safety line 32 has a certain elasticity that can improve the freedom of the guest using the safety line 32.

As shown in fig. 4 and 5, an opening 312 is opened at a position of the hanging ring 31 close to the safety rope 32, and the width of the opening 312 is larger than the diameter of the cross section of the vertical bracket 11. A baffle shaft 313 which is vertically arranged is fixedly connected to the position of the hanging ring 31 close to the opening 312, a baffle 314 is rotatably connected to the baffle shaft 313, and the baffle 314 can cover the opening 312. The baffle shaft 313 is sleeved with a torsion spring 3131, one end of the torsion spring 3131 is fixedly connected to the hanging ring 31, the other end of the torsion spring 3131 is fixedly connected to the baffle 314, and the baffle 314 covers the opening 312 when the torsion spring 3131 is in a natural state. When the hanging ring 31 moves along the hanging rope 3 and passes through the vertical bracket 11, the vertical bracket 11 can pull the baffle 314 open, so that the hanging ring 31 can smoothly pass through the vertical bracket 11, and after the hanging ring 31 passes through the vertical bracket 11, the baffle 314 can cover the opening 312 again under the action of the torsion spring 3131, so that the probability that the hanging ring 31 falls off from the hanging rope 3 can be reduced.

As shown in fig. 4 and 5, a rotary wheel opening 315 is formed in the hanging ring 31, a rotary shaft 3151 perpendicular to the length direction of the hanging rope 3 is fixedly connected to a position of the hanging ring 31 close to the rotary wheel opening 315, a rotary wheel 3152 is rotatably connected to the rotary shaft 3151, a hanging groove 3153 matched with the hanging rope 3 is formed in the rotary wheel 3152, and the hanging rope 3 can be slidably connected to the hanging groove 3153. When the hanging ring 31 moves along the hanging rope 3, the rotary wheel 3152 rolls on the hanging rope 3, so that the friction force between the hanging ring 31 and the hanging rope 3 can be effectively reduced, and the hanging ring 31 can move more smoothly.

In a using mode, when a person moves on the suspension bridge, the climbing buckle 322 on the safety rope 32 can be hung on the body, the safety when the person passes through the suspension bridge is improved, meanwhile, the folding protection mechanism 2 can also provide certain buffering for people when the person falls or falls, and the probability of danger of the person is reduced.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
