Anti-rotation self-locking semitrailer for bottle type high-pressure containers

Abstract

The invention relates to an anti-rotation self-locking semitrailer for bottle type high-pressure containers. The anti-rotation self-locking semitrailer comprises a frame, an operation box, a fixed steel plate and bottle-type containers, wherein the bottle-type containers are horizontally placed on the frame by layers, each layer constitutes one group, the frame is provided with a parking strut, the fixed steel plate is fixed on the frame and is provided with a plurality of screw holes, threads are arranged on two ends of each bottle-type container, spare caps are arranged on the rear parts of the threads, bottle flanges are arranged on the front parts of the threads and are provided with screw holes, a fixed sleeve is arranged between each bottle flange and the corresponding spare cap, the middle part of each bottle container is provided with a plurality of fixed interlocking devices, and a contact-type parking brake valve is arranged inside the operation box. The invention provides the semitrailer capable of effectively preventing the containers from rotation and vibration.

Description

Technical field [0001] The invention belongs to the field of bottle-type high-pressure container transport vehicles, and particularly relates to an anti-rotation self-locking bottle-type high-pressure container semi-trailer. Background technique [0002] At present, the bottle-type high-pressure container used in domestic bottle-type high-pressure container transport vehicles is made of high-strength steel. According to relevant national regulations and standards, welding structure is not allowed on the container body. For this reason, only mechanical structure Bottle-type containers impose constraints. At present, positioning pins are usually installed at the end of the bottle mouth to prevent the container from rotating. Due to the small diameter of the bottle mouth and the bottle body as long as 11000mm, it is difficult to effectively prevent the container from rotating and vibrating, especially When transporting high-pressure, flammable, and highly toxic hazardous chemicals, ...

AI Technical Summary

Problems solved by technology

[0002] At present, the bottle-type high-pressure container used in domestic bottle-type high-pressure container transport vehicles is made of high-strength steel. According to relevant national regulations and standards, welding structures are not allowed on the container body. For this reason, only mechanical structures can be used. Bottle-type containers impose constraints. At present, the method of installing positioning pins at the end of the bottle mouth is often used to prevent the rotation of the container. Due to the small diameter of the end of the bottle mouth and the length of the bottle body as long as 11000mm, it is difficult to effectively prevent the rotation and vibration of the container, especially When transporting high-pressure, flammable and highly toxic hazardous chemicals, it is very easy to cause safety accidents, which is not conducive to the safe operation of transport vehicles

[0003] In addition, when the transport vehicle is loading and unloading, due to the negligence of the relevant operators, it often occurs that the loading and unloading pipeline is not disconnected, and the operation box door is not closed before driving, which often leads to safety accidents
