Crane trolley and monorail hoist with same

Abstract

The invention discloses a crane trolley and a monorail hoist with the same. At least one pair of anti-releasing boards, which axially and oppositely extend along wheels and are in blocking fit with the upper track surface of a corresponding I-steel rail, are fixed at the front end and / or the back end of a trolley frame of the crane trolley; and a gap through which the corresponding I-steel rail passes is arranged between the two opposite anti-releasing boards. According to the crane trolley provided by the invention, as the at least one pair of anti-releasing boards, which axially and oppositely extend along the wheels and are in blocking fit with the upper track surface of the corresponding I-steel rail, are fixed at the front end and / or the back end of the frame of the crane trolley, when a small wheel bearing is damaged or broken, the crane trolley can be suspended on the I-steel rail through the two anti-releasing boards, so that major safety accidents caused by the falling of the whole monorail hoist can be effectively avoided. The monorail hoist has the advantages of simple structure and convenience in mounting; the potential safety hazard of the falling of the whole monorail hoist can be effectively overcome; and the safe and stable operation of the monorail hoist can be ensured.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and particularly relates to a monorail crane used for running on an I-beam rail and a crane trolley installed on the monorail crane. Background technique [0002] Monorail crane, commonly known as electric hoist, is a small lifting equipment hoisted on a suspended track. This monorail crane is mainly composed of two parts: a crane trolley for moving back and forth along the I-beam track and a hoisting mechanism for lifting heavy objects. Chinese Invention Patent Publication CN102211738A discloses a small radius of curvature electric hoist crane trolley. The crane trolley includes mounting plates that are placed on both sides of the I-beam rail at relative intervals, and are relatively assembled on the two mounting plates, which are respectively connected to the I-beam. The rails on both sides of the steel correspond to the small wheels for rolling fit and the connecting bolts connecte...
