The invention relates to a pay-off spool two-level brake device of a steel bar truss. The device comprises a rotary shaft bracket, a bearing frame, a rotary shaft, a plane bearing, a friction plate, brake teeth, rotation teeth, an outer linkage plate, a tension spring, an inner linkage plate, a pull rod seat, a pull rod, a rotary arm, a main shaft, a main shaft seat and a base, wherein the rotary shaft is connected with the rotary arm; the rotary arm is rotatably connected with the pull rod; and the front end of the pull rod is rotatably connected with the pull rod seat. One end of the pull rod seat is connected with the tension spring, and the other end is rotatably connected with a middle seat. One end of the tension spring is fixed on the base. The middle seat is rotatably connected with the outer linkage plate and the inner linkage plate; the inner linkage plate is provided with the friction plate; and the friction plate faces the rotary shaft bracket. The brake teeth are arranged on the inner linkage plate; the rotation teeth are arranged at the lower end of the rotary shaft bracket; and the rotation teeth are meshed with the brake teeth. The device provided by the invention has a simple, compact and reasonable structure, and is convenient and quick to use and maintain; through mutual match between the friction speed reducing and gear braking, the efficiency of the equipment is greatly improved; and by adopting the connecting rod for control, the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to a secondary brake device for a pay-off reel of a steel bar truss. Background technique [0002] With the development of the economy, steel trusses are becoming more and more popular in industries such as petroleum, shipbuilding, construction, mining, public roads, energy and decoration. [0003] The steel truss automatic welding machine is a device for welding steel trusses, which can improve production efficiency and reduce the labor intensity of workers. The brake device of the pay-off reel is an important part of the steel truss automatic welding machine, which realizes the rapid conversion of the pay-off reel from the rotating state to the stopped state. The pay-off reel braking device of the existing truss automatic welding machine adopts the control cylinder pressurization to increase frictional resistance so that the pay-off reel stops rotating. It requires an additional control system, thus increasing costs. At the s...
