Fator de risco do equipamento mecânico e medida protetoraMechanical equipment risk mainly is the movement part of the equipment, such as transmission mechanism and cutter, movement work piece and chip, etc. If the equipment has defect, protective device failure or improper operation, it could cause personal casualty accident at any time.
1, mechanical transmission mechanism can be divided into gear transmission, chain transmission and belt transmission. If the component does not conform to the requirement, such as mechanical design is unreasonable, transmission part and outstanding transmission part exposed, unprotected, etc., or its own security protection consciousness is poor, don't be careful and peccancy operation may handle, clothes haul in the harm.
2, mechanical equipment rotating parts and moving parts, mechanical equipment, has a very big risk. Its rotating parts, such as drill, wrap silk machine rotating work piece chuck, etc. once with people clothing, sleeves, long hair entwined, easy life or personal injury accident; Operator operation method is undeserved, too hard, use the tool specification is unreasonable, are likely to make the operator bumped on machine tools. The operator and construction personnel stand position is not appropriate; Cutter cuts etc will pose a threat to personal safety.
Therefore, do some protective measures for mechanical equipment. For example mechanical transmission mechanism, for safety protection gear transmission, you must install protective device fully enclosed, without a guard shall not be used; for safety belt drive, adopt the method of the belt cover all, or installation of protective railings for protection. For coupling safety protection, the most fundamental way is to add shield. To install safety device, such as overload safety device, travel insurance device, brake device, etc.
As a worker, operating equipment must be in strict accordance with the required dress; when the machine is running, no adjustment or measuring the work piece with hands; work piece and cutter card wants firm, banned touch rotating parts of the machine. Please responsible for own safety.
