Bailey pin and using method thereof

Abstract

The invention discloses a Bailey pin and a using method thereof. The Bailey pin comprises a pin body and a positioning blocking piece; a flange is arranged at the second end of the pin body, penetrating through holes are formed in the side face of the first end, and the middle portions of the through holes expand outwards to form a cavity; a transverse limiting hole is formed in the first end, oneend of the transverse limiting hole extends out of the end face, the other end of the transverse limiting hole communicates with the cavity, and a clamping table is arranged on the inner wall of thetransverse limiting hole; the positioning blocking piece comprises a spring, safety pins and a rotating body for clamping the safety pins, the safety pins are of T-shaped structures and comprise transverse baffles and vertical rods, the transverse baffles of the two safety pins are located in the cavity and abut against the two ends of the spring correspondingly, and the vertical rods extend intothe through holes; and the rotating body is clamped in the limiting hole through the clamping table and can rotate in the limiting hole, a transverse containing groove for containing the transverse baffles is formed in the end, facing the cavity, of the rotating body, tooth openings are formed in the groove wall, part of the transverse baffles enters and exits from the containing groove through the tooth openings, and the transverse baffles are clamped into or disengaged from the containing groove under rotation of the rotating body. The Bailey pin is simple in structure, convenient to use andefficient, and loss, loosening, breakage and the like of the safety pins can be avoided so that construction safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of Bailey bridge connecting components, in particular to a Bailey pin. Background technique [0002] The Bailey Bridge is the most widely used and most popular bridge in the world. It has the characteristics of simple structure, convenient transportation, quick erection, and easy disassembly. It also has the advantages of large bearing capacity, strong structural rigidity, and long fatigue life. It can form temporary bridges, emergency bridges and fixed bridges of various types and uses according to the different needs of actual projects, and has the characteristics of few components, light weight and low cost. Bailey bridges are usually composed of trusses, truss connecting pins and safety pins, reinforcing chords, chord screws, truss bolts, etc. Among them, the truss is also called Bailey frame, which is a steel frame forming a certain unit, which can be spliced ​​and assembled into many components and eq...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that in the prior art, the truss connection pins are separated from the safety pins, which are not easy to store and are easy to lose. In addition, during the actual installation or removal process, it is easy to cause the safety pins to fall off and be damaged, especially during high-altitude installation. , under the action of wind, the components collide with each other, which will cause the safety pin to be damaged or fall off, which will cause a safety hazard
