Abstract

Provided is an asphalt cavity device locked through D-shaped bolts. Two asphalt outlets are symmetrically formed in the bottom of an asphalt cavity and fixed through a set of symmetrical fasteners. D-shaped bolt fastening openings are formed in the tops of the asphalt outlets, the D-shaped bolts are mounted in the D-shaped bolt fastening openings, and fastening pins are arranged at the bottoms of the asphalt outlets. The fastening pins are used for fixedly connecting the asphalt outlets with the asphalt cavity, and the D-shaped bolt fastening openings and the D-shaped bolts are used for connecting the asphalt outlets and the asphalt cavity in a locking mode. The asphalt cavity device is of a sealed structure, and the asphalt outlets and the asphalt cavity can be completely locked by rotating the D-shaped bolts by 180 degrees. Compared with traditional full-bolt locking, the asphalt cavity device locked through the D-shaped bolts has the characteristics of being high in locking speed and convenient to lock.

Description

technical field [0001] The invention relates to a device for locking an asphalt cavity with a D-shaped bolt, belonging to the technical field of asphalt application machinery. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch: wherein, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] The stre...
