Mechanical balance weight type airplane service support lifting platform

Abstract

The invention relates to the technical field of the aviation product manufacturing process and aircraft daily maintenance and guarantees, and particularly discloses a mechanical balance weight type airplane service support lifting platform. The mechanical balance weight type airplane service support lifting platform comprises an outer well lid assembly, an inner well lid assembly, a hand-lifting lock assembly, a foot-stepping lock assembly and a sliding bearing assembly. The outer well lid assembly comprises an outer well lid, fixed guide rails and a pulley assembly. The pulley assembly is installed on the outer sides of the fixed guide rails. The inner well lid assembly comprises an inner well lid, movable guide rails and a connection beam. The connection beam is installed on the inner sides of the two movable guide rails. The hand-lifting lock assembly is installed on the inner well lid. The foot-stepping lock assembly is installed on the connection beam. The sliding bearing assembly is installed on the movable guide rails. The movable guide rails slide along the fixed guide rails through the sliding bearing assembly. The mechanical balance weight type airplane service support lifting platform has the beneficial effects that the inner well lid is controlled to move and stop through mechanical locks, and the safety reliability is high; the sliding bearing assembly ensures that the inner well lid part operates stably, and the cable abrasion is relieved; and the pulley assembly prevents a balance weight assembly from interfering with other parts, and noise is reduced.

Description

technical field [0001] The invention relates to the technical field of aviation product manufacturing process and aircraft daily maintenance and support, in particular to a mechanical balance counterweight type aircraft service support lifting platform. Background technique [0002] Mechanical balanced lifting integrated support platform This equipment is used for the integration and carrying of energy facilities (air source system, ground power system, hydraulic system, air conditioning system, etc.) required in the manufacturing process of aviation products and the daily maintenance and support of aircraft. According to the actual use of the equipment, it is divided into infield use and outfield use. According to the operation mode of the equipment, it is divided into mechanical balance lift type and electric lift type; mechanical mechanical balance lift type is divided into single-side counterweight type and double-side counterweight type according to the placement form o...
