Embodiment Construction

[0017] The specific embodiment of crane trolley of the present invention is for example figure 1 , figure 2 As shown, the crane trolley includes mounting plates 1 that are placed on the left and right sides of the I-shaped steel rail 5 at relative intervals. The front and rear wheels 3 are fixed with connection plates 21 corresponding to the front and rear extensions at the two ends of the two mounting plates 2 in the front and rear directions respectively, and the ends of the connection plates 21 are respectively along the axis of the wheel 3. To the opposite extension, there is an anti-off plate 22 suspended on the top of the I-steel track 5 for stopping and cooperating with the upper track surface on both sides of the I-steel track. through the gap. The ends of each connecting plate 21 are also respectively extended along the axial direction of the wheel 3 to be provided with a support plate 23 suspended under the corresponding lower track surface of the I-shaped steel t...

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 in particular relates to a monorail crane running on an I-shaped steel track and a crane trolley installed on the monorail crane. Background technique [0002] Monorail crane, commonly known as electric hoist, is a small lifting device that is 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 lifting mechanism for lifting heavy objects. Disclosed in the Chinese Invention Patent Publication Document CN102211738A is a small curvature radius electric hoist crane trolley. This crane trolley includes mounting plates that are placed on both sides of the I-shaped steel track at relative intervals, and are relatively assembled on the two mounting plates. The rails on both sides of the steel rails correspond to the small wheels with rolling fit and the connecting bolts connected to the l...
