Description

Tension rod dismounting device

Technical Field

The utility model relates to the technical field of track slab production, in particular to a tension rod dismounting device.

Background

The high-speed railway track slab is generally manufactured by pouring concrete materials into a track slab mold, solidifying the concrete materials to form concrete blocks, and demolding the concrete blocks. In order to improve the strength of the track slab and facilitate the formation of concrete materials, steel bars may be embedded in the concrete. However, in the process of concrete solidification, stress is easily generated between the concrete material and the steel bars, so that the steel bars are easily cracked or broken in the process of solidifying the concrete material from a semi-fluid state to a solid state. Therefore, in the production process of the track slab, a certain prestress, i.e., a prestress tension process, needs to be applied to the reinforcing steel bars.

The tension rod is used as a part for applying prestress to the steel bar in the production process of the track slab, the tension rod and the prestress steel bar are required to be screwed together before the track slab is poured, and the steel bar is compressed through a nut on the tension rod, so that the steel bar keeps the prestress. Specifically, the tensioning rod penetrates through the side wall of the track plate mold, and the nut on the tensioning rod is fixedly pressed, so that the nut is matched with the side wall of the track plate mold to generate certain prestress on the steel bar even if the tensioning rod applies certain force on the steel bar.

After the concrete material is completely solidified, the application of the tensile stress needs to be stopped, and at the moment, the tensile tension rod needs to be taken out of the track slab mold.

The method for disassembling the tension rod for the track slab in the prior art is mainly manual. Although this method is flexible and simple, it has a great disadvantage in the operation process. For example: the number of the tension rods on the track plate mould is as large as dozens, so that the manual operation extraction efficiency is low and the labor intensity is high; the rail plate mould automatically runs on the production line, and certain potential safety hazards also exist when constructors operate on the production line.
