As shown in fig. 1-4, the utility model provides a technical solution:

temporary protection device of bridge construction, including rail guard main part 1, rail guard main part 1 is including the fixed fence 104 of installation, the fixed fence 104 of installation includes two spacing posts 142 of frame, it is connected with elastic expansion band 141 to rotate between two spacing posts 142 of frame, in this embodiment, elastic expansion band 141 can stretch relatively long distance under the exogenic action, and elastic expansion band 141's fixed surface is connected with the crooked stand 103 of a plurality of centre grippings, consequently, when elastic expansion band 141 is stretched, the distance between each crooked stand 103 of centre gripping also can increase, and after the exogenic force disappears, elastic expansion band 141 retracts, make each crooked stand 103 of centre gripping fold, make it only occupy less space when accomodating. One side of each of the two frame limiting columns 142 is fixedly connected with a clockwork spring storage box 2, an elastic protective net 3 is wound and stored inside one of the clockwork spring storage boxes 2, and one end of the elastic protective net 3 extends into the other clockwork spring storage box 2. In this embodiment, two storage rollers are disposed inside the two spring storage boxes 2, two ends of the elastic protection net 3 are wound on the storage rollers, and an elastic steel ring serving as a spring is disposed on the storage rollers and connected to the elastic protection net 3, so that when the whole device is stretched, the elastic protection net 3 is pulled out, the steel ring is tightened, and when external force disappears, the steel ring releases to drive the elastic protection net 3 to retract, and simultaneously the storage rollers rotate to wind the elastic protection net 3 thereon, thereby reducing the length of the external elastic protection net 3 and also reducing the volume of the device when being stored. In this embodiment, when the device is deployed, the length of the elastic expansion band 141 which is pulled apart can be adjusted according to actual conditions, and then the fixed platform 143, the column base 135 and the bridge deck are fixed, and the directional beam 102 is installed. It should be noted that the elastic bands 141 cannot be stretched too much, so that the distance between the two top holders 101 exceeds a positioning beam 102, and too long is likely to cause damage to the elastic bands 141.

Every crooked stand 103 of centre gripping includes stand base 135, and top one side of stand base 135 is rotated and is connected with active crooked post 133, and active crooked post 133 is articulated mutually by a plurality of small segments of initiative post and is formed, and one side of every small segment of initiative post all is fixed spiro union respectively has a gim peg 138, and the one end of every gim peg 138 all is fixed spiro union has the driven post of small segment. An elastic connecting column 137 is fixedly connected between every two small-section driven columns, the small-section driven columns are combined into a driven bending column 136 through the elastic connecting column 137, and the bottom end of the driven bending column 136 is rotatably connected with the upright column base 135. It should be noted that the elastic connecting column 137 has elasticity and flexibility, and thus can be extended as the bending time interval of the driven bending column 136 increases. In this embodiment, the active bending column 133 faces the site of the bridge construction, so if someone bumps into the protection device, the elastic expansion band 141 is driven to stretch, and naturally, the active bending column 133 is also bent, and the active bending column 133 drives the driven bending column 136 to rotate, thereby forming a space for accommodating the collider, so as to dissolve the impact force generated by the collider, and the active bending column 133 and the driven bending column 136 are arranged so that the elastic expansion band 141 is not excessively deformed, so that the collider pops out of the bridge floor, or excessively rebounds, and the collider falls down. The top ends of the driving bending column 133 and the driven bending column 136 are fixedly connected with a top platform 131, the bottom ends of two sides of the top platform 131 are respectively and fixedly connected with an elastic upright column 132, and the bottom ends of all the elastic upright columns 132 are fixedly connected with an upright column base 135. In this embodiment, each of the minor segment driving post and minor segment driven post is provided with a fixed collar on both sides so that the elastic post 132 can pass therethrough, so that the elastic post 132 maintains a bending state consistent with that of the driving bending post 133 and the driven bending post 136, and rebounds after the external force disappears, so that the clamping bending post 103 is returned to the right. The top ends of each top platform 131 and the frame limiting columns 142 are fixedly connected with two groups of top clamping seats 101, the inner sides of the two groups of top clamping seats 101 are fixedly clamped with a directional beam 102, a gap exists between every two directional beams 102, and the bottom ends of the two frame limiting columns 142 are fixedly connected with a fixing platform 143 respectively. In this embodiment, the directional beams 102 are distributed on two sides of the elastic extensible band 141, and the directional beams 102 on two sides have the same length and are distributed in a staggered manner, so that a section of the two opposite directional beams 102 always coincides with each other, thereby forming a nearly-connected total beam, preventing the top end of the elastic extensible band 141 from inclining outwards when the elastic extensible band 141 is stretched, and allowing a person who collides with the elastic extensible band 141 to be thrown out from above. One end of each fixing bolt 138 is fixedly connected with a fixing hook 134, and one end of each fixing hook 134 is hooked with the elastic protection net 3. So that the elastic protection net 3 is tightly clamped on the surface of the curved upright post 103 to provide buffer for the impacter. In this embodiment, the fixing hook 134 is small, smooth in edge, and facing inward, and will not hurt the user.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
