Buffer device of travelling crab

Abstract

The invention relates to a buffer device of a travelling crab for achieving an effective buffering function when heavy objects with various specifications are hoisted. The buffer device comprises a cart guide rail, the travelling crab and two limiting baffle plates, wherein the travelling crab is arranged on the cart guide rail, the two limiting baffle plates are arranged at the ends of two sides of the cart guide rail respectively, the travelling crab comprises a frame, wheels and a plurality of parts, the wheels are arranged on the cart guide rail and are movably linked with the frame, the plurality of parts are fixedly connected to the frame, the buffer device is arranged at the end of the frame and comprises a speed measurement device, an electric current control device, two baffle plates and a plurality of electromagnets. The buffer device can achieve the buffering function when the heavy objects with various specifications are hoisted, energy is saved and resource waste is reduced.

Description

technical field [0001] The invention relates to a buffer device on a crane trolley. Background technique [0002] In factories, construction sites and other places, cranes are often used to lift heavy objects. Cranes generally move horizontally or vertically through the guide rails of the cart and the crane trolley on it to realize the lifting of heavy objects. However, the crane trolley It must also move within the limited range of the cart guide rail, so the buffer device becomes an indispensable part to slow down the impact of the crane trolley on the limit baffle. At present, the buffer devices of crane trolleys mostly use elastic connectors such as springs, but these elastic connectors cannot make immediate changes in response to sudden situations because they are rigidly fixed. If the rigidity is too large, the elastic connector cannot function when lifting lighter objects; if the rigidity is too small, the elastic connector cannot function when lifting heavier object...
