Description

Protective device for roller chain of quenching machine Technical Field The invention relates to the technical field of protection of metallurgical equipment, in particular to a protection device for a roller chain of a quenching machine. Background In the production process of the medium plate, a quenching machine roller way is usually driven by a motor through a chain and sprocket system. During operation of the apparatus, the chain, sprocket, etc. is in a high-speed rotation. The prior art has the following prominent problems: First, the potential safety hazard is big. Rotating parts such as a roller chain and a chain wheel of the quenching machine are usually exposed, and clothes, tools and the like of operators and point inspection personnel are easily involved in the rotating parts in the operation process, and even the human bodies are in direct contact with the rotating parts, so that serious mechanical injury accidents are caused. In addition, the chain may break during high speed operation, and the broken chain splashes may cause object striking injury to surrounding personnel. Second, the maintenance time is long. The roller chain of the quenching machine is easy to damage due to long-term high-speed operation and needs to be replaced periodically. At present, the safeguard measure that most equipment adopted is only simple and easy iron wire binding type guardrail, and not only dismantlement and installation are loaded down with trivial details, consuming time long, and guardrail itself is heavy moreover, leads to the operation time of changing the chain to increase by a wide margin, seriously influences the normal operating efficiency of production line. Therefore, a novel protection device capable of effectively isolating rotating parts and guaranteeing personnel safety and facilitating daily spot inspection and rapid maintenance is needed. Disclosure of Invention The invention aims to solve the technical problem of overcoming the defects of the prior art and providing a protection device for a roller chain of a quenching machine. In order to solve the technical problems, the technical scheme of the invention is as follows: A protective device for a roller chain of a quenching machine, comprising: The fixed frame is fixedly arranged on the quenching machine body and is positioned at the outer side of the roller chain of the quenching machine; the protection plate is arranged in the fixed frame in a sliding manner along the length direction of the fixed frame and is used for shielding the roller chain of the quenching machine. As a preferable scheme of the protection device for the roller chain of the quenching machine, the invention comprises a fixed frame, a roller chain and a roller chain, wherein the fixed frame comprises an upper cross beam and a lower cross beam which are parallel up and down and are arranged at intervals; The upper cross beam and the lower cross beam are fixedly arranged on the quenching machine body, and the protection plate is slidably arranged between the upper cross beam and the lower cross beam. As a preferable scheme of the protection device for the roller chain of the quenching machine, the upper cross beam and the lower cross beam are both I-steel, and the opening side of the upper cross beam and the opening side of the lower cross beam are oppositely arranged; The upper end and the lower end of the protection plate are respectively arranged in the grooves of the upper cross beam and the lower cross beam in a sliding manner. As a preferable scheme of the protection device for the roller chain of the quenching machine, a plurality of protection plates are arranged, and the protection plates are sequentially distributed along the length direction of the fixed frame; The thickness of the protection plate is smaller than half of the width of the groove.
