The movable railing 12 is in a horizontal state in the initial state, the height of the movable railing 12 is the height of the limited height at the moment, the movable railing 12 plays a role in limiting the height during normal use, when a special ultrahigh vehicle is encountered, the driving motor 18 is started, the driving motor 18 drives the intermediate shaft 17 to rotate through the output end, the intermediate shaft 17 drives the driven shaft 63 to rotate, the fixed railing 14 is driven to rotate by taking the driven shaft 63 as the axis through the driving motor 18 and the railing installation piece 13 in sequence, the movable railing 12 rotates, the rotating direction is upward and the rotating angle is ninety degrees, the movable railing 12 is in a vertical state at the moment, the movable railing 12 is kept in the vertical state at the moment after the driving motor 18 is closed after ninety degrees of rotation, and the special ultrahigh vehicle can normally pass through at the moment.
When the superelevation vehicle forces through the limit for height pole, after movable railing 12 bumps with the vehicle, the vehicle gives movable railing 12 a horizontal pivoted power to make movable railing 12 and railing mounting 13 coact on threaded fastener and a shearing force, when the shearing force is greater than threaded fastener's shear strength, movable railing 12 rotates along articulated shaft 16 level, thereby make movable railing 12 and vehicle area of contact diminish and finally break away from the contact with the vehicle, thereby reduce the damage degree to movable railing 12, make movable railing 12 can not break and can repetitious usage.
In the process of passing the vehicle and controlling the rotation of the movable rail 12 by the operation of the driving motor 18, the body of the installation box 10 vibrates, the long-time vibration can lead to loosening of the nut piece due to the threaded connection of the long bolt 24 and the nut piece, so that the fastening degree of the two parts of the connecting metal hoop 20 is reduced, the risk of loosening and sliding of the installation box 10 exists, in the process of vibrating the body of the installation box 10, the rotation post 30 is rotationally connected with the installation box 10 due to the joint of the long bolt 24 and the rotation post 30 above, in the process of vibrating the body of the installation box 10, in the process of vibrating the installation box 10, the installation box 10 slightly rotates around the joint of the rotation post 30 and the installation box 10, so that the lower part of the installation box 10 swings in a small range by taking the joint of the rotation post 30 and the installation box 10 as the axis, in the swinging process of the installation box 10, because the inflation box 40 is fixedly connected with the installation box 10, at this time, the sliding column 46 slides in the sliding cavity 42 relative to the sliding cavity 42, when the sliding column 46 slides in the sliding cavity 42, the sliding column 46 presses the sealing column 44 towards the inflation chamber through the abutting block 43, so that the gas in the inflation chamber enters the gas delivery pipe 22 through the gas channel 48 and passes through the micro check valve 47, and then is guided into the wear-resistant expansion layer 23 by the gas delivery pipe 22, so that the wear-resistant expansion layer 23 expands, when the wear-resistant expansion layer 23 expands, the pressure between the wear-resistant expansion layer 23 and the cylinder surface is increased, so that the friction force between the wear-resistant expansion layer 23 and the cylinder surface is increased, the axial pressure of the connecting ferrule 20 acting on the nut member is also increased, the teeth in the nut member are tightly attached to the engaging teeth on the surface of the long bolt 24, so that the friction force is increased, and the speed of loosening of the nut is slowed down, at the same time, the distance between the two semicircular portions of the coupling ferrule 20 becomes large, and a larger distance is occupied by the expansion of the abrasion-resistant expansion layer 23.
When the semicircular part in the connecting metal hoop 20 close to one side of the mounting box body 10 is continuously far away from the column, namely the expansion size of the wear-resistant expansion layer 23 is further increased, the connecting metal hoop 20 pushes the pressing column 51 to slide into the mounting box body 10, so that the extruding plate 32 is driven to move in a direction far away from the column;
as the distance between the two semicircular parts of the connection ferrule 20 becomes larger gradually, the stability of the mounting box 10 is also reduced gradually, when the larger distance between the two semicircular parts of the connection ferrule 20 reaches the guard value, the extrusion plate 32 is in contact with the elastic clamping joint 34 at this time, when the distance between the two semicircular parts of the connection ferrule 20 becomes larger further, the extrusion plate 32 gradually extrudes and deforms the elastic clamping joint 34, and when the elastic clamping joint 34 is extruded to a certain extent, i.e. when the distance between the two semicircular parts of the connection ferrule 20 becomes larger to reach the dangerous value (the dangerous value and the guard value are determined according to the friction coefficient of the wear-resistant expansion layer 23 and the cylinder surface, and the sliding stroke of the extrusion plate 32 can be adjusted according to the actual situation), the extrusion plate 32 extrudes the elastic clamping joint 34 to deform the elastic clamping joint 34 completely, so that the width of the elastic clamping joint 34 is smaller than the width of the bayonet, and the elastic clamping joint 34 is separated from the bayonet joint;
the resistance of the connecting rope 35 against the pulling force of the pulling rope 36 (namely the elasticity of the spiral spring) after the connection is released is changed from the sum of the limiting force of the elastic clamping joint 34 abutting against the bayonet and the elasticity of the pressing spring 62, the sum becomes the single pulling force of the elastic force of the pressing spring 62 against the pulling force of the pulling rope 36, at the moment, the elastic force of the pressing spring 62 is smaller than the pulling force of the pulling rope 36, thereby the winding wheel 53 is driven to rotate forward under the action of the spiral spring, the connecting rope 35 is dragged by the pulling rope 36 to the cavity direction in the winding box 52, the connecting rope 35 is wound on the surface of the winding wheel 53, meanwhile, the connecting rope 35 gradually becomes smaller along with the gradual winding of the connecting rope 35 on the surface of the winding wheel 53, at the moment, the connecting rope 35 pulls the limiting clamping block 61 to move away from the driven shaft 63, the pressing spring 62 is further compressed, at the moment, the driven shaft 63 can rotate freely relative to the intermediate shaft 17 under the action of the high-strength torsion spring 60, at the moment, the driven shaft 63 rotates rapidly relative to the intermediate shaft 17 (namely, the driven shaft 12 is driven to overturn upwards by ninety degrees through the motion process), the moving rail body 12 is driven by the motion, and the moving upwards, the rail body 12 is prevented from sliding upwards when the rail body 12 is mounted on the vertical rail body, and the rail body 12 is prevented from sliding upwards, and the rail body is prevented from sliding upwards, and falling upwards when the rail body 12 is in a situation.
When the installation box 10 slides from the vertical column of the portal frame, if the above process is unable to elastically reset due to aging of the spiral spring, when the reel 53 rotates to wind the connecting rope 35 onto the surface of the reel 53, at this time, in the falling process of the installation box 10, because the safety rope 37 is bound at the upper end of the portal frame, when the installation box 10 moves downwards, the safety rope 37 is fixed in length, at this time, the connecting rope 35 is pulled to move upwards by the safety rope 37, because the upward pulling force is larger at this time, the pulling force is larger than the sum of the elastic force of the pressing spring 62 and the limiting force of the elastic clamping head 34 against the bayonet, at this time, the elastic clamping head 34 is forcibly pulled out from the bayonet, and the limiting clamping block 61 is pulled out from the driven shaft 63 through the connecting rope 35, at the same time, the connecting rope 35 pulls the pulling rope 36 to reversely rotate the reel 53 (namely, the spiral spring is further compressed), at this time, the pulling rope 36 is gradually released from the surface of the reel 53 and enters the internal space of the installation box 10, when the limiting clamping block 61 is in the driven shaft 63, the turnover of the movable rail 12 can be completed through the above process, the situation that the turnover of the spiral spring 12 can not be avoided, and the integral failure of the movable rail 12 can be avoided.
