Description

Bridge crane for container

Technical Field

The invention mainly relates to the field of cranes, in particular to a bridge type container crane.

Background

The bridge crane is a hoisting device which is transversely arranged above workshops, warehouses and stockyards to hoist materials. Since its two ends are seated on a tall concrete column or a metal bracket, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated frames at two sides, so that the space below the bridge frame can be fully utilized to hoist materials without being hindered by ground equipment. The lifting machine has the widest application range and the largest quantity. The common crane is only provided with a single hoisting structure, the hoisting mode is single, the crane can be hoisted only by adjusting an external device in the transverse direction, and the single hoisting of the large-sized objects such as containers can be unstable.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a bridge crane for a container, which comprises a bridge frame 1, wherein the bridge frame 1 is provided with two crane rails which are respectively fixed on walls on two sides and slide through a running mechanism 2, two ends of the two bridge frames are connected through a transverse rail, a travelling trolley 3 is fixed in the transverse rail and slides through a running structure 301, the travelling trolley 3 is provided with two lifting structures, each lifting structure comprises a pulley block and a motor, a hook is arranged at the bottom of the pulley block, and the two lifting structures independently move and can be synchronously lifted or asynchronously lifted.

Preferably, a cable drum 8 is arranged between the two hoisting structures of the operating mechanism 2.

Preferably, the two ends of the two bridges are connected with the conductive frames 4, and the conductive frames 4 are positioned on the outer sides of the transverse rails.

Preferably, the running mechanism 2 comprises a roller and a motor, and the motor drives the roller to rotate on the running track.

Preferably, the operation structure 301 includes a roller and a motor, and the motor drives the roller to rotate on the transverse rail.

Preferably, the hook is connected with a container lifting appliance, and the lifting appliance is provided with a clamp used for clamping the top of the container.

Preferably, the hook is connected with a hanging rope, and the hanging rope is sleeved on the container.

The invention has the beneficial effects that:

the two sets of lifting structures can work in a combined mode, the weight of a lifted object is larger, the lifting process is more stable, deviation is avoided, and the large object can be lifted without other auxiliary devices.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1 to 4, the present invention includes:

the utility model provides a container bridge crane, includes crane span structure 1, and crane span structure 1 is equipped with two, fixes respectively at the driving track on the wall of both sides and slides through running gear 2, and the both ends of two crane spans are through horizontal track connection, and travelling car 3 fixes and slides in horizontal track and through running gear 301, travelling car 3 is equipped with two hoisting structure, and hoisting structure includes assembly pulley and motor, and the bottom of assembly pulley is equipped with the couple, and two hoisting structure independent activity can go up and down in step or not step up and down.

In the present embodiment, a cable drum 8 is preferably provided between the two hoisting structures of the running gear 2.

In the present embodiment, it is preferable that the two bridges are connected to the conductive frame 4 at two ends, and the conductive frame 4 is located outside the transverse rail.

In this embodiment, the running mechanism 2 preferably includes a roller and a motor, and the motor drives the roller to rotate on the running rail.

In this embodiment, the operation structure 301 preferably includes a roller and a motor, and the motor drives the roller to rotate on the transverse track.

In this embodiment, it is preferred that the hook is connected to a spreader, which is provided with a clamp for clamping the top of the container.

In this implementation, it is preferable that the hook is connected with a hanging rope, and the hanging rope is sleeved on the container.

The working principle is as follows:

the container is sleeved by the hanging ropes under the hook and respectively sleeved at the two ends of the container, and the container is lifted by the two lifting structures or lifted by the lifting appliance under the hook. Simultaneously, the two hoisting structures can also adjust different heights so as to meet the requirements of hoisting and placing containers with different requirements. .
