Device for positioning and resisting flotation of embedded part of track slab

Abstract

The invention discloses a device for positioning and resisting flotation of an embedded part of a track slab, which comprises a positioning column, wherein the positioning column is fixedly connected with a bottom mold of a track slab mold; a radial pin hole is arranged at the upper part of the positioning column; a flotation resisting pin is installed at one end in the radial pin hole, and a flat head screw is installed at the other end in the radial pin hole; a spring is clamped between the flotation resisting pin and the flat head screw; and the flotation resisting pin is provided with an end part which extends out of the pin hole and is matched and clamped with the screw thread of the embedded part. In the invention, a structure of installing and clamping the flotation resisting pin and a sealing ring between the positioning column and the embedded part is adopted, thereby avoiding the problems of swinging and floating upward of the embedded part due to vibration; the embedded part can be positioned accurately, and the forming quality of the track slab can be ensured easily; the embedded part can be tightly screwed on the bottom mold in a rotating and screwing mode, thereby having high efficiency and humanization and relieving the physical labor; and the invention has simple structure, convenient use and low cost.

Description

technical field [0001] The invention relates to a positioning device for embedded parts, in particular to a device for positioning and anti-floating of embedded parts of track slabs. Background technique [0002] At present, the positioning of the embedded parts of the track slab adopts the method of tightening the positioning column in the embedded part. The positioning column is fixed on the surface of the mold. When the concrete is cast, the track slab mold is under the action of the oscillator, and the embedded Swing occurs, so that the embedded parts of the track will float up, and the concrete will enter the embedded parts of the track, and the embedded parts will be tilted, so that the track plate will be scrapped. Parts are easy to float, so the quality of the track slab cannot be guaranteed, and the labor intensity of the workers is high, the efficiency is low, the structure is complicated, and the cost is high, which is completely unable to adapt to the development...
