Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] The front end, rear end, left side, and right side described in the present invention are for convenience of description, without any limitation.

[0027] Such as Figure 2 to Figure 3 As shown, a preferred double trolley bridge type crane with opposite directions moving in the present invention is taken as an example with the fetching device being a grab bucket 100, and the fetching device can also be a container spreader or a hook and other fetching devices.

[0028] Such as figure 2 As shown, the bridge type crane with double trolleys moving in opposite directions includes four outriggers 11 at front, rear, left and right and a cart traveling system that drives the crane to walk. , ...

Abstract

The invention discloses a bridge crane with double trolleys moving in different directions. The bridge crane is characterized in that a first track is arranged above a bridge, and a machine room trolley moves on the first track; a second track is arranged below the bridge, and a hoisting trolley moves on the second trolley; a first driving mechanism for driving the machine room trolley to travel is mounted on the machine room trolley; a second driving mechanism for driving the hoisting trolley to travel is mounted on the hoisting trolley; and when the second driving mechanism drives the hoisting trolley to travel, the first driving mechanism drives the machine room trolley to travel in a reverse direction relative to the hoisting trolley. The bridge crane has load tipping moment servo-balancing and partial movement inertia force offsetting effects, so that crane shaking caused by operation of the hoisting crane is alleviated, and the hoisting trolley is positioned accurately; the maximum working wheel pressure is reduced, and the stability coefficient of the crane is increased; and the main span of the crane is small, so that the dead weight and cost of the crane can be lowered.

Description

technical field [0001] The invention relates to hoisting and transporting machinery, in particular to bridge type cranes. Background technique [0002] A bridge type crane refers to a crane in which the pick-up device is suspended on a lifting trolley that can move along the bridge. Typical ground (platform) track mobile bridge type cranes include (gantry) gantry cranes and loading and unloading bridges. [0003] The overall structure of the gantry crane is mainly composed of a bridge frame (or a bridge frame with outriggers), front and rear outriggers and a walking beam, and has three working mechanisms such as lifting, cart, and trolley travel. According to its use, it can be divided into general-purpose hook gantry cranes; 2-purpose gantry cranes such as hook grabs and hook electromagnetics; 3-purpose gantry cranes with hook grab electromagnetics; freight yard container gantry cranes (referred to as yard bridges) and Shipbuilding gantry cranes and more. [0004] The lo...
