Problems solved by technology

The above parking control method relies heavily on the absolute encoder and field bus communication. When the absolute encoder or field bus and other equipment fail, it is difficult for the ejector trolley with large inertia and high speed to stop safely, which may cause serious damage to the equipment. , poor device security

Abstract

The invention discloses an ejector rod trolley parking device and a perforating machine with the ejector rod trolley parking device. The ejector rod trolley parking device comprises a buffering track, a buffering mechanism and a travel switch. The buffering track is connected to the parking end of a main track so that an ejector rod trolley can continuously move along the buffering track when reaching the parking end but still not stopping. The buffering mechanism comprises two buffering assemblies arranged on the two sides of the buffering track. Each buffering assembly comprises a fixing plate and a buffering plate. The fixing plates are fixed to one side of the buffering track and are parallel to the buffering track. The buffering plates are connected to the sides, facing the buffering track, of the fixing plates through multiple elastic pieces. The interval between the two buffering plates is smaller than the width of the ejector rod trolley. The travel switch is arranged on the buffering mechanism to induce the stress travel of the buffering plates. By the adoption of the ejector rod trolley parking device and the perforating machine with the ejector rod trolley parking device, when the ejector rod trolley fails, safe parking of the ejector rod trolley can be achieved, damage to equipment is avoided, and good safety is achieved.

Description

technical field [0001] The invention relates to the technical field of steel rolling equipment, in particular to a parking device for a ejector trolley and a piercing machine provided with the parking device for a ejector trolley. Background technique [0002] The ejector trolley of the existing punching machine is dragged by a steel wire rope, reciprocates in a section of fixed track, and is braked by a brake pad installed on the transmission shaft of the reduction box. During the parking process of the existing ejector trolley, there is a lack of a special safety parking device. Instead, an absolute encoder is used to measure the position pulse, and the actual position of the trolley is calculated by the PLC, and the PLC sends the start-stop signal and the speed setting to the transmission. The above parking control method relies heavily on the absolute encoder and field bus communication. When the absolute encoder or field bus and other equipment fail, it is difficult fo...
