Embodiment Construction

[0030] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0031] See figure 1 and figure 2 , figure 1 It is a schematic diagram of the overall structure of the bridge crane of the present invention, figure 2 Yes figure 1 A view from direction A.

[0032] like figure 1 and figure 2 As shown, the bridge crane described in this embodiment is mainly composed of a bridge 1 , a bridge running mechanism 2 , a lifting trolley 3 , a telescopic arm 4 and a telescoping running mechanism 5 .

[0033] Wherein, the bridge running mechanism 2 drives the bridge 1 to run longitudinally along the tracks on the elevated beams 9 on both sides; the lifting trolley 3 runs transversely along the tracks on the bridge 1; the telescopic arm 4 is arranged on Between the lifting trolley 3 and the bridge 1, the lifting trolley 3 runs laterally along the track on the telescopic arm 4; the telescopic running mechanism 5 drives the telescopic a...

Abstract

The invention discloses a bridge crane and relates to the movable hoisting machinery technology. The invention includes a bridge, a bridge traveling mechanism, a crane trolley, a telescopic boom and a telescopic traveling mechanism; wherein the bridge traveling mechanism drives the bridge to travel longitudinally along the track on elevated beams on the two sides; the crane trolley travels laterally along the track on the bridge; the telescopic boom is arranged between the crane trolley and the bridge, the crane trolley travels laterally along the track on the telescopic boom; and the telescopic traveling mechanism drives the telescopic boom to travel laterally along the track on the bridge. During the operation of aisle freightage, the invention first starts the telescopic traveling mechanism, the telescopic boom is driven by a transmission mechanism to extend to the adjacent span and is matched with the lateral movement and the lifting operation of the crane trolley at the same time, so that the goods can be transferred to the destination without any other auxiliary transportation devices, and the transportation process is reduced, thereby lowering cost and improving production efficiency.

Description

technical field [0001] The invention relates to a movable hoisting machine, in particular to a bridge crane. Background technique [0002] Bridge type crane, also known as crane. Ordinary bridge type crane is composed of lifting trolley, bridge running mechanism, and bridge metal structure. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, and the lifting trolley runs horizontally along the tracks laid on the bridge frame. With a rectangular working range, the space under the bridge frame can be fully used to lift materials without being hindered by ground equipment. [0003] At present, bridge type cranes are widely used in indoor and outdoor warehouses, workshops, docks and open-air storage yards, etc., especially for factory buildings, they are necessary auxiliary equipment. [0004] The factory building is generally composed of several spans, and the same type of work is one span, that is, a work area. ...
