The movable railing 12 is the horizontality under the initial condition, the height that the height of movable railing 12 was the limit for height this moment, movable railing 12 plays the limit for height effect during normal use, when meetting special superelevation vehicle, start driving motor 18, make driving motor 18 drive jackshaft 17 through the output and rotate, thereby make jackshaft 17 drive driven shaft 63 rotate, thereby loop through driving motor 18 and railing installed part 13 and drive fixed railing 14 and use driven shaft 63 to rotate as the axle center, thereby make movable railing 12 take place to rotate, the direction of rotation is upwards and the turned angle is ninety degrees, movable railing 12 is vertical state this moment, driving motor 18 closes this moment movable railing 12 and maintains vertical state after rotating ninety degrees, special superelevation vehicle can normally pass through this moment.
When super high vehicle is forced to pass through the limit for height pole, movable railing 12 bumps the back with the vehicle, the vehicle gives movable railing 12 a level pivoted power, thereby make movable railing 12 and railing installed part 13 combined action shearing force on threaded fastener, 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 diminish with vehicle area of contact finally break away from the contact with the vehicle, thereby reduce the destruction degree to movable railing 12, make movable railing 12 can not break and can repetitious usage.
During the process of the vehicle passing through and the driving motor 18 operating to control the rotation of the movable rail 12, the body of the installation box 10 vibrates, since the long bolt 24 is in threaded connection with the nut member, the nut member is loosened due to long-time vibration, so that the fastening degree of the two parts of the connecting metal hoop 20 is reduced, and the installation box 10 is in risk of loosening and sliding, during the vibration of the body of the installation box 10, the rotating column 30 is in rotational connection with the installation box 10 at the connection position of the upper long bolt 24 and the rotating column 30, during the vibration of the installation box 10, the installation box 10 slightly rotates at the connection position of the rotating column 30 and the installation box 10, so that the installation box 10 swings in a small range with the connection position of the rotating column 30 and the installation box 10 as an axis, during the swinging of the installation box 10, since the inflating box 40 is fixedly connected with the installation box 10, 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 sliding block 43 to press the sliding column 46 against the surface of the sliding block of the sliding cavity 42, so as to press the inner surface of the expanding gas of the sliding column 23 to increase the gas in the conveying pipe, thereby increasing the axial direction of the wear-resistant pipe, and increasing the pressure of the wear-resistant pipe 23, and increasing the gas in the wear-resistant pipe 23, and increasing the pressure of the wear-resistant pipe 23, and increasing the wear-resistant pipe 23, at the same time, the distance between the two semicircular portions of the connecting ferrule 20 becomes larger, and the extra distance is occupied by the expanded wear-resistant expansion layer 23.
When the semicircular part in the connecting metal hoop 20 close to one side of the installation box 10 is continuously far away from the column, that is, the expansion size of the wear-resistant expansion layer 23 is further increased, at this time, the connecting metal hoop 20 pushes the pressing column 51 to slide towards the installation box 10, so as to drive the extrusion plate 32 to move towards the direction far away from the column;
as the distance between the two semicircular parts of the connecting ferrule 20 gradually increases, the stability of the mounting box 10 also gradually decreases, when the increasing distance between the two semicircular parts of the connecting ferrule 20 reaches an alert value, the pressing plate 32 abuts against the elastic clamping head 34, when the distance between the two semicircular parts of the connecting ferrule 20 further increases, the pressing plate 32 gradually presses and deforms the elastic clamping head 34, and the elastic clamping head 34 is pressed to a certain extent, that is, when the distance between the two semicircular parts of the connecting ferrule 20 increases to a dangerous value (the dangerous value and the alert value are determined according to the friction coefficient between the wear-resistant expansion layer 23 and the surface of the cylinder, and can be adjusted according to the actual situation, that is, the sliding stroke of the pressing plate 32 is adjusted), the pressing plate 32 presses and completely deforms the elastic clamping head 34, so that the width of the elastic clamping head 34 is smaller than the bayonet width, and the elastic clamping head 34 is disengaged;
after the connection rope 35 is separated from the clamping state, the resistance of the connection rope 35 to resist the pulling force of the pulling rope 36 (namely, the elastic force of the scroll spring) is changed from the sum of the limiting force of the elastic clamping joint 34 abutted to the bayonet and the elastic force of the pressing spring 62, to the sum of the elastic force of the elastic clamping joint 34 and the bayonet, the elastic force of the pressing spring 62 singly resists the pulling force of the pulling rope 36, at this time, the elastic force of the pressing spring 62 is smaller than the pulling force of the pulling rope 36, so that the reel 53 is driven to rotate forward under the action of the scroll spring, thereby the connection rope 35 is dragged towards the cavity direction in the winding box 52 by the pulling rope 36, so that the connection rope 35 is wound on the surface of the reel 53 along with the pulling rope 36, at the same time, the connection rope 35 is wound on the surface of the reel 53 gradually, the length of the connection rope 35 becomes smaller gradually, at this time, the connection rope 35 pulls the limiting fixture block 61 to move towards the direction far away from the driven shaft 63, the pressing spring 62 is further compressed, when the limiting fixture 61 is completely separated from the driven shaft 63, at this time, the driven shaft 63 can freely rotate relative to the intermediate shaft 17, at this time, under the effect of the high-strength torsion spring 60, the driven shaft 63 can make the driven shaft rotate relative to rotate rapidly (namely, the driven shaft 63 can drive the driven shaft 63 to reach ninety degree upwards through the rail 12, thereby, so as to keep the rail installed on the rail 12, and the rail post 12, so as to avoid the rail post 12, when the rail can be installed in time, and the rail can be installed in the vertical and the rail.
When the installation box 10 slides down from the vertical column of the portal frame, if the process cannot be elastically reset due to the aging of the volute spiral spring, the connection rope 35 is wound on the surface of the winding wheel 53 by the rotation of the winding wheel 53, at the moment, 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 length of the safety rope 37 is fixed, at the moment, the safety rope 37 pulls the connection rope 35 to move upwards, because the upward pulling force is larger at the moment, 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 joint 34 abutted against the bayonet, at the moment, the elastic clamping joint 34 is forcibly pulled out from the bayonet, the limiting clamping block 61 is separated from the driven shaft 63 through the connection rope 35, meanwhile, the connection rope 35 pulls the pulling rope 36 to enable the winding wheel 53 to rotate reversely (namely, the volute spiral spring is further compressed), at the moment, the pulling rope 36 is gradually released from the winding state from the surface of the winding wheel 53 and enters the inner space of the installation box 10, when the limiting clamping block 61 is separated from the rail 63, the inside of the rail 12, the movable shaft 12 can be overturned through the process, and the process can be avoided, the situation that the safety of the movable spring can not be improved, and the safety of the rail.
