Description

Sleeper truss drag hook equipment mechanism

Technical Field

The utility model relates to a sleeper production technical field especially relates to a sleeper truss drag hook equipment mechanism.

Background

The high-speed rail sleeper is a concrete sleeper block paved below a high-speed rail steel rail to support the high-speed rail steel rail, buffer the pressure on the steel rail and maintain the flatness of the surface of the steel rail. The high-speed rail sleeper is manufactured by placing a truss and filling concrete in a mould, and cooling and forming the high-speed rail sleeper. The concrete material poured at the two ends of the truss needs to have enough thickness and strength, so that the truss and the matched stirrups need to be preset in the mould before the concrete is poured so as to have a supporting function after the concrete material is solidified.

Because the requirement of the high-speed rail on the flatness is higher than that of a common railway, the thickness of concrete at two ends of a truss of the high-speed rail sleeper needs to be kept consistent, and an important factor influencing the thickness of the concrete is the distance between a stirrup and the truss. In order to maintain the distance between the stirrup and the truss, a plurality of thin steel wires are generally bound between the stirrup and the truss, and the length maintained by the bound thin steel wires is the distance between the stirrup and the truss. However, the production mode needs to artificially bind the thin steel wires, and the production efficiency is low. And because the stirrup plane and the truss plane need to be parallel to each other in the binding process, the operation difficulty is high, and if the binding force of each thin steel wire is not uniform, the stirrup plane and the truss plane are easy to lose the parallel relation.

In order to improve the above problem, hooks with uniform specification and shape can be generated in advance, generally, the hooks are formed by bending thin steel wires at two ends respectively, and the two ends of the hooks are hung on the truss and the stirrups respectively, so that mutual installation between the truss and the stirrups is realized, and the parallel relationship between the stirrup plane and the truss plane can be maintained by the gravity action of the stirrups. In actual production, the assembly among the hook, the stirrup and the truss can be completed through truss assembly equipment.

Generally, the truss assembling equipment can grab the hook through the clamping device with the lifting function, then the bottom end of the hook is connected with the stirrups, the hook and the stirrups are carried to move upwards, and after the truss is parked at a position, the top end of the hook is hung on the truss. The mode of assembling the hook can easily cause the hook assembly failure because the stirrup swings in the moving process and the stirrup is separated from the bottom end of the hook. Meanwhile, as a plurality of hooks are often required to be installed between the stirrups and the truss, and after one hook is assembled, the other hooks cannot complete the assembling mode, a control action program needs to be rewritten, or a plurality of clamping devices simultaneously act, even if the mode has high error rate.
