AI Technical Summary

Technical Problem

The existing tanker truck guardrails can still be selectively raised or lowered manually even when not in use, posing a safety hazard, especially when loading hazardous materials, which could lead to serious personal safety risks.

Method used

Design a fencing device including a fence, a safety gate, and a control system. The safety gate is linked to the fence so that the fence automatically rises when the safety gate is opened. The fence is also linked to the unloading guardrail to ensure that the safety gate can only be opened during the unloading process, preventing operation by non-professionals.

Benefits of technology

This effectively ensured the automatic raising of the fence, standardized the operating procedures for workers, prevented accidents, and improved operational safety.

Abstract

The embodiment of the application provides a tank truck and a fence device. The fence device comprises a fence, a safety door and a control system. The fence is arranged on the top of a tank body; the fence comprises a horizontal rod, a plurality of vertical rods arranged at intervals and a power member connected with at least one vertical rod; the top end of each vertical rod is rotatably connected with the horizontal rod, and the bottom end is rotatably connected with the top of the tank body; the power member drives the vertical rod to rotate, so that the vertical rod is rotated upward to be erected and unfolded or is rotated downward to be folded; the safety door comprises a door body surrounding the lower part of a ladder and capable of being opened and closed relative to the ladder and a locking member locking the door body and the ladder; the locking member is connected with the power member; the control system is connected with the locking member and is used for controlling the locking member to switch between a locking state and a release state; when the locking member is in the release state, the door body can be opened relative to the ladder, and the power member drives the vertical rod to rotate to the erected and unfolded state. Through linkage of the safety door and the fence, the effective lifting of the fence is ensured, and safety is ensured.
