Truss for bridge-crossing device
The invention discloses a truss for a bridge-crossing device. The truss for the bridge-crossing device comprises a fixed truss and a movable truss, wherein the fixed truss is telescopically matched with the movable truss by means of a rolling mechanism; the fixed truss and the movable truss are of frame structures; the cross sections of the fixed truss and the movable truss are rectangles. The truss for the bridge-crossing device has the characteristics that a first reinforcement rod is arranged in each of not more than two first square frames at one end, not connected with the movable truss, of the fixed truss. The length of each first reinforcement rod is 1/2 of that of a first diagonal web member; each first reinforcement rod is perpendicular to the corresponding diagonal web member in first square frame in which the first reinforcement rod is positioned; one end of each first reinforcement rod is connected with the middle of the corresponding diagonal web member; the other end of each first reinforcement rod is connected with a corresponding corner of the corresponding first square frame. According to the truss for the bridge-crossing device, the used materials are few; the welding spots are few; the welding process is simple; the production cost is low; the weight is light; the size is small; the structure is simple; the control accuracy is high; the discomfort brought to a truss passenger is avoided. The truss for the bridge-crossing device is suitable for the passage of personnel and materials between a marine living platform and a supply ship.
