High-temperature billet transport vehicle with automatically opened and closed carriage door

Abstract

The invention discloses a high-temperature billet transport vehicle with an automatically opened and closed carriage door, and belongs to the technical field of special article transportation. The vehicle comprises a frame and wheels at the bottom, a bottom plate is arranged on the frame, a front carriage plate and a rear carriage plate are respectively arranged at the front end and the rear end of the frame; side carriage plates with the upper portions bent inwards are hinged to the two sides of the frame. At least two carriage plate connecting rods are hinged to the side carriage plates, frame connecting rods are hinged to the bottom ends of the carriage plate connecting rods, the other ends of the frame connecting rods are hinged to the bottom of the frame, telescopic oil cylinders arehinged to the ends, close to the carriage plate connecting rods, of the frame connecting rods, and oil cylinder supporting bases installed at the bottom of the frame are hinged to the other ends of the telescopic oil cylinders. The whole structure strength is high, the side carriage plates are balanced in stress, small in deformation in use, large in opening angle and large in operation space, thetelescopic oil cylinders are arranged at the bottom, the vehicle body is shorter, narrower and lighter, influence of the environment on a hydraulic system is small, influence of heat diffused upwardsin the carriage on the telescopic oil cylinders at the bottom is small, and the hydraulic system has a self-locking function, can be remotely controlled and is good in safety.

Description

technical field [0001] The invention belongs to the technical field of transportation of special articles, in particular to a high-temperature steel billet transportation vehicle with automatic opening and closing of compartment doors. Background technique [0002] Iron and steel enterprises are the largest energy consumers in my country's industrial enterprises. After the molten steel is poured and continuously cast into billets in the steelmaking plant, the billets need to be transported to the rolling mill for heating and rolling. In order to facilitate the hoisting of steel billets, the existing steel billet transport vehicles generally do not have a box body. After the steel billet is completed, it needs to be cooled first, and then hoisted to the support plate of the vehicle to fix it. When it is transported to the rolling mill, it needs to be reheated and rolled, resulting in unnecessary heat. waste. Due to the limitation of the site, the hot rolling processing of h...

Problems solved by technology

[0005] In order to solve the problem of long intervals of steel billets transported by railways, large temperature drop, high energy consumption for reheating, easy damage to the outer heat radiation, poor mobility, high maintenance costs, and the large volume of existing steel billet transport vehicles, the requirements for the entire hydraulic system High, the telescopic oil cylinder is greatly affected by the temperature of the billet and is easily damaged, and the opening angle of the compartment door is small. The invention provides a high-temperature billet transport vehicle with automatic opening and closing of the compartment door
