Suspension type container overload and unbalanced load detection device

Abstract

The invention relates to a suspension type container overload and unbalanced load detection device which comprises a locking rod. One end of the locking rod is provided with a locking head for matching a container, and the other end of the locking rod is provided with a thread to form a connection end. A force measurement section is formed at the middle part of the locking rod. The outer ring of the force measurement section is provided with a resistance strain gauge which winds around the locking rod in a ring to be attached to the force measurement section of the locking rod. The connection end of the locking rod is axially provided with an axial wire through hole. The force measurement section of the locking rod is provided with radial wire through hole. The inner end of the axial wire through hole communicates with the inner end of the radial wire through hole. A conductive wire goes through the radial wire through hole and the axial wire through hole to be connected to the resistance strain gauge. In the locking rod used by the detection device, the resistance strain gauge is designed to be a ring-shaped structure on the locking rod, thus the circumferential and comprehensive detection of the force measurement section of the locking rod can be realized, and the detection precision is improved. The setting of a mounting hole in the locking rod is avoided, and the tensile strength of a spin lock is improved.

Description

technical field [0001] The invention relates to a detection device for overweight and unbalanced load of a suspended container. Background technique [0002] Twist locks are needed in container lifting operations to lock the four corners of the container and then lift them. In order to detect the force on the twist locks, sensors are now installed on the twist locks. Traditionally, sensors are installed As introduced in the previous patent (Patent No.: 201310215502.1), the twist lock of the twist lock is mainly installed symmetrically on both sides of the twist lock. The cross-sectional area in the middle weakens the tensile strength of the twist lock, and it is easy to break when lifting, which affects safety. Secondly, this installation method in the past cannot realize the stress detection on the entire circumference of the lock rod, there is a blind area, and the detection is not accurate.
