Posture-adjustable collision dummy for simulating underground operation of coal mine

Abstract

The invention belongs to the technical field of coal mine safety equipment detection, and solves the problem that only standing dummy targets exist in the detection of an active safety auxiliary driving system and cannot simulate the real posture characteristics of coal mine underground operating personnel. The posture-adjustable collision dummy comprises a dummy trunk, dummy upper limbs, dummy hips, dummy lower limbs and an auxiliary supporting device, the auxiliary supporting device comprises a connecting rod, a standing posture supporting rod, a bending posture supporting rod and a squatting posture supporting rod, a center pipe is fixed to the lower end of the dummy trunk, and a center pipe is fixed to the lower end of the center pipe. The connecting rod is rotationally connected to the lower end of the central tube and can be locked at different posture positions, the standing posture supporting rod is connected to the lower end of the connecting rod when the dummy stands or prostrates, the prostrating posture supporting rod is connected to the lower portion of the front chest of the dummy trunk when the dummy prostrates, and the squatting posture supporting rod is connected to the lower end of the connecting rod when the dummy squats. According to the invention, different postures of the dummy are converted, and simulation of various posture characteristics of underground coal mine operating personnel is realized.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety equipment detection, and in particular relates to a posture-adjustable collision dummy for simulating underground operations in a coal mine. Background technique [0002] Due to the narrow and harsh underground environment of coal mines, extrusion and collision accidents between equipment and personnel are more likely to occur in the process of mining and transportation in coal mines. In the analysis and research on coal mine accidents in the past, the cause of the accident was generally attributed to the four aspects of "human, machine, environment, and management", and the unsafe behavior of people and the unsafe state of equipment were the direct causes of the accident. The Automatic Brake Assist (AEB) system is installed on some coal mine vehicles to reduce the occurrence of collisions. [0003] Automatic Brake Assist System (AEB) refers to the normal form of the vehicle in the case ...

AI Technical Summary

Problems solved by technology

[0007] Considering that the coal mine underground environment is relatively complex, the working status of the operators includes standing, leaning and squatting postures. In the detection of the active safety assisted driving system, only the standing dummy target cannot simulate the real posture of the coal mine underground workers. Insufficient features, the object of the present invention is to provide a collision dummy with adjustable posture for simulating underground operations in coal mines, replace the corresponding auxiliary struts for different postures, and adjust the distance between the dummy torso and the lower limbs of the dummy. angle to realize the simulation of the physical characteristics of real coal mine workers
