Embodiment Construction

[0026] 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.

[0027] Such as Figure 2 to Figure 4 Shown, the present invention's preferred a kind of double trolley opposite direction mobile bridge type crane of the present invention, is to take the object device is grab bucket as example, also can fetch object device is the object device such as container spreader or hook.

[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 mechanism 110 that drives the crane to walk. The bridge frame 13 is an outrigger structure. A first track is arranged above the bridge frame 13, and the machine room trolley 12 moves on the first ...

Abstract

The invention discloses a double-trolley opposite-direction movement bridge type crane. A first rail is arranged on a bridge, and a machine room trolley moves on the first rail; a second rail is arranged below the bridge, and a crane carriage moves on the second rail; four hoisting drums are mounted on the machine room trolley; a drive mechanism for driving the machine room trolley to walk is mounted on the machine room trolley. The double-trolley opposite-direction movement bridge type crane achieves a quite good partial offset function on load tipping moment follow-up balance and motion inertia force, waggling of the crane caused by operation of the crane carriage is relieved beneficially, and positioning accuracy of the crane carriage is improved; the maximum working wheel pressure is reduced, and the stabilizing coefficient of the crane is increased; a small crane main span is achieved, weight of the crane can be lowered, and infrastructure investment of the crane is reduced.

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), outriggers and walking beams, 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 loading and unload...
