Buffered sliding mechanical limiting device

Abstract

The invention discloses a buffered sliding mechanical limiting device, which belongs to the technical field of limitations to the motions of revolution bodies. The device comprises a movable limiting block, a left limiting combination and a right limiting combination, wherein the movable limiting block is wholly cambered, and is fixedly connected to the revolution part of revolution equipment; the left and right limiting combinations are identically structured and symmetrically arranged; each of the left and right limiting combinations comprises a limiting seat, a sliding block and pressure plates; a limiting damper is arranged in the limiting seat; the sliding block is provided with a cavity; four corners at the lower end of the sliding block are outwards extended to form a sliding rod respectively; the limiting seat is fixedly connected to the fixed part of the revolution equipment; the pressure plates and the limiting seat form four guide sliding rails; the sliding block is sleevedon the limiting seat; one side of the sliding block contacts the limiting damper; and each sliding rod on the sliding block is positioned in corresponding guide sliding rails. When the movable limiting block impacts the sliding block, the limiting damper absorbs the moment of inertia of the revolution equipment to weaken the rigid impact force of the revolution equipment and finally stop the revolution of the revolution equipment. The buffered sliding mechanical limiting device has the advantages of convenience of assembly and disassembly, long service life, impact resistance, high safety, high universality and the like.

Description

technical field [0001] The invention belongs to the technical field of movement limit of a revolving body, and mainly relates to a mechanical limit device, in particular to a buffer type sliding mechanical limit device. Background technique [0002] In many application fields, rotary equipment often needs to rotate forward and reverse. During the slewing process, the cables in the equipment mechanism rotate around the central axis and twist at the same time. In order to prevent the cables on the equipment from being twisted and causing the entire system to collapse, it is usually necessary to install a special slewing limit mechanism on the equipment to reliably control the equipment. range of rotation angle. Chinese patent ZL200720149011.1 discloses a "universal shaft angle limiting device", which includes a shaft core, a lever, a stop piece, a bump, and a stop pin assembly, which can meet the angle limit requirements of various turntable equipment, but the There is no el...
