Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and more specifically to an improved double-beam bridge crane. Background Art

[0002] Double-girder crane generally refers to double-girder bridge crane. Double-girder crane is generally composed of three major parts: mechanical, electrical and metal structure. The appearance of bridge crane is a single-span flat bridge supported at both ends on two parallel overhead rails. Double-girder crane is widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals and logistics turnover departments and places.

[0003] When unloading, the cranes of the prior art generally remove the cargo from the hook manually, which is not only inconvenient to remove the cargo, but also the heavier cargo puts greater pressure on the hook, making it extremely difficult to remove the cargo from the hook, and may also pinch or abrade the hands of the personnel, which is dangerous.

[0004] Based on the above background, an improved double-beam bridge crane is proposed to solve the problems raised. Utility Model Content

The double-beam frame is installed on the base frame, and a transverse movement device is arranged on the double-beam frame, and the transverse movement device is transmission-connected with the transmission rod. The motor is installed on the support plate and is transmission-connected with the transmission rod. The support plate is connected to the transverse movement device, and a traveling hoist is arranged under the support plate. The upper side of the lifting rope is connected to the traveling hoist and the lower side is connected to the rotating wheel. The rotating wheel is located on the mounting seat, and a hook is rotatably arranged under the mounting seat. An opening and closing assembly is installed on one side of the mounting seat and is rotationally connected with the hook; wherein the opening and closing assembly comprises a gasket, a cylinder, an ear plate, a rotating rod, and a bearing. The gasket is installed on one side of the mounting seat, the cylinder is arranged on the gasket, and the lower side of the cylinder is connected with an ear plate. A bearing is arranged on one side of the hook and is connected to the rotating rod, and the rotating rod is passed through the ear plate.

[0008] Preferably, the cylinder body of the cylinder is mounted on the gasket, and the rod body is connected to the ear plate.

[0009] Preferably, the gasket is made of rubber.

[0010] Preferably, a sleeve for housing a lifting rope is connected to the lower side of the traveling hoist.

[0011] Preferably, a baffle is connected to the lower side of the mounting seat.

[0012] Preferably, the hook is rotatably connected to the baffle via a shaft.
