AI Technical Summary

Technical Problem

When a refueling truck raises its chassis after refueling, the trailing strip may not have enough contact with the ground or may even detach from it, causing static electricity to fail to dissipate in time. This poses a risk of static electricity buildup that could ignite the oil tank.

Method used

Design an automatic adjustment device for the tow strip of a refueling truck, including an installation component, a first roller, a second roller, and a rotary drive component. The rotary drive component drives the rollers to rotate, adjusting the length of the tow strip to ensure full contact with the ground and prevent it from slipping off.

Benefits of technology

It enables automatic adjustment of the tow strip length, avoiding safety accidents caused by insufficient contact length or detachment from the ground, extending the service life of the tow strip and improving driving safety.

Abstract

This invention relates to the field of fuel truck tow belt length adjustment technology, and more specifically, to an automatic tow belt adjustment device for fuel trucks. The device includes a mounting assembly, a first roller, a second roller, and a rotary drive assembly. The axes of the first and second rollers are parallel to each other and are rotatably connected to the mounting assembly. A clamping cavity for the tow belt to pass through is formed between the first and second rollers. The rotary drive assembly is mounted on the mounting assembly. This invention overcomes the shortcomings of existing technologies where the tow belt may have insufficient contact length with the ground or even detach from the ground when the fuel truck chassis is raised. By setting up a rotary drive assembly, a first roller, and a second roller, the tow belt is clamped between the first and second rollers during use. The rotary drive assembly drives either the first or second roller to rotate, thereby moving the tow belt and adjusting its contact length with the ground. This avoids safety accidents caused by insufficient contact length or detachment of the tow belt from the ground.
