Grab Overhead Crane Warehouse

Abstract

The invention discloses a warehouse with a bridge grabbing crane. The warehouse comprises the bridge grabbing crane which is transversely arranged at the top of the warehouse. The bridge grabbing crane can move back and forth in the length direction of the warehouse and is provided with grab buckets which can move back and forth along the bridge grabbing crane. An overhead trestle is longitudinally arranged below the bridge grabbing crane, and the operating direction of the overhead trestle is the same as the operating direction of the bridge grabbing crane. The overhead trestle is located in the position of the longitudinal center line of the warehouse. A feeding conveyer is arranged on the bridge surface of the overhead trestle. A discharging conveyer is longitudinally arranged below the overhead trestle. Receiving hoppers are arranged on the discharging conveyer. The warehouse with the bridge grabbing crane has the advantages that firstly, the way that feeding and discharging are conducted in the warehouse is adopted, and uniform operation is facilitated; secondly, the two grab buckets are used for grabbing materials, and thus the production capacity and the working efficiency are improved; thirdly, the discharging height is reduced, raising dust is reduced, and the operating environment of the warehouse with the bridge grabbing crane is improved; and finally, the way that discharging is conducted in the warehouse is adopted, part of facilities outside the warehouse are omitted, and construction investment cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanized transportation of powder materials in chemical enterprises, in particular to a grab bridge crane warehouse. Background technique [0002] In the field of mechanized transportation of powder materials in chemical enterprises, grab bridge crane warehouses are often used, and conveyors are used for transportation equipment entering and leaving the warehouse. According to Article 4.2.4 of the Chemical Industry Standard of the People's Republic of China "Code for Design of Chemical Powder Material Yards and Warehouses" HG20568-2014, "Mechanized Transportation Process Design Manual" (Chemical Industry Press, 1998.4, 1st Edition, pp. 213, 214), the The prior art of similar warehouses usually uses the following layout schemes: the equipment for transporting materials into the warehouse adopts the feed conveyor at the side of the warehouse (such as figure 1 shown), or use the feed conveyor at the top of the ware...

AI Technical Summary

Problems solved by technology

[0004] (1) When the feed conveyor located at the side of the warehouse is used, the transfer empty travel of the grab bridge crane trolley is long, the efficiency is low, the working capacity is low, and the homogenization operation cannot be performed;

[0005] (2) When the feed conveyor located on the top of the warehouse is used, homogenization operation can be performed, but the height of the warehouse is high, and the investment in civil construction is large; the dust is large during unloading, which affects the operation of the crane and shortens its service life;

[0006] (3) The discharge conveyor needs to be equipped with a trestle or an underground corridor, which increases the floor area and civil construction investment
