An enhanced auxiliary support device

Abstract

The utility model relates to an enhanced auxiliary support device, including a base, a support arm and a hydraulic cylinder. Support arms of a roller shaft of a support roller are hinged forward on both sides of the base. Hydraulic cylinders are respectively arranged on both sides of the base. Rod joints of the hydraulic cylinders are hinged to the middle of the support arms. A horizontal support seat and a vertical support seat are arranged at the front end of the support arm. Both the horizontal and vertical support seats include a seat frame, a pin shaft and a roller. Two rollers supporting the roller shaft upward and backward are connected between the side frames of the two seat frames through the pin shaft. A horizontal roller that fits the lower end of the roller shaft is used for upward support, and a vertical roller that fits the front end of the roller shaft is used for backward support, so as to stably and rotatably support the roller shaft. The hydraulic cylinder is used to control the lifting and lowering of the support arm through a lever group. When the steel belt is pulled forward under tension and sent out, the tension of the roller and the roller shaft is buffered to avoid damage caused by the direct action of the traction force on the roller shaft and the roller.
