Description
Technical Field
The utility model relates to a conveying equipment, specifically speaking are a two pendulum rod formula safety barrier mechanisms of lift that is used for on multilayer broken rail transfer chain.
Background
In the automobile production, in order to meet the production and process requirements, the conveying operation of products is often required to be carried out among multiple floors (including three or more floors), most of the conveying operation is completed by adopting a lifter, a movable rail is arranged on the lifter, and fixed rails are respectively arranged on the floors.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel structure, easily installation and debugging, safe and reliable, with low costs, long service life's lift double pendulum rod formula safety barrier mechanism.
In order to achieve the purpose, the utility model comprises a rotating shaft, a connecting plate, a reset component, two supports and two stop rods, wherein each stop rod comprises a roller shaft, a roller, a screw I, a swing arm, a screw II and an anti-collision block, the two ends of the rotating shaft are respectively provided with a square tenon, the reset component comprises a swing rod, an extension spring and an ear plate, the upper part of the swing rod is provided with an annular hook, the roller is arranged at the lower end of the swing arm through a roller shaft, the anti-collision block is arranged at the upper end of the swing arm through a screw II, the two supports are arranged in the middle of the connecting plate in a bilateral symmetry manner, the ear plates are welded on the upper part of the connecting plate, the lower end of the swing rod is welded in the middle of the rotating shaft, one end of the extension spring is connected with the lug plate, the other end of the extension spring is connected with an annular hook at the upper part of the swing rod, the rotating shaft is arranged in the holes of the two supports in a penetrating way, the two blocking rods are symmetrically arranged on the square tenons at the left end and the right end of the rotating shaft respectively by adopting a screw I.
The utility model adopts two stop rods symmetrically arranged at the left end and the right end of the rotating shaft, and the two stop rods are usually arranged on the movable rail of the lifter, so that when one of the two stop rods is impacted by the impact head arranged on the fixed rail butted with the stop rod, the stop rods can swing at the same time to leave the movable rail, and at the moment, a trolley arranged on the movable rail can pass through smoothly; and the return mechanism consisting of the swing rod, the extension spring and the lug plate is adopted, so that when the movable rail on the elevator is not butted with the fixed rail, the movable rail can sequentially pass through the swing rod and the rotating shaft under the action of the tension of the extension spring, two stop rods symmetrically arranged at the left end and the right end of the rotating shaft can swing at the same time to be close to the movable rail, and at the moment, a trolley arranged on the movable rail can be prevented from falling off from the movable rail, thereby improving the reliability and the safety. The utility model discloses novel structure easily installs and debugs, safe and reliable, and is with low costs, long service life.
