Description

A new type of lifting equipment

technical field

The invention relates to a novel hoisting device, which belongs to the field of port machinery.

Background technique

Large ships need to use the cranes on the docks to load and unload goods at the docks. These cranes are generally relatively large, and the tail of the cranes is generally equipped with relatively heavy counterweights to keep the cranes in balance during the operation. However, in typhoon weather The heavy counterweight will bring unsafe factors to the crane, and the wind can easily blow the crane over. Therefore, this is an urgent problem to be solved.

Contents of the invention

The object of the present invention is to provide a novel lifting device.

The problem to be solved by the present invention is the defect that the existing wharf crane is easy to overturn in the windy day.

For realizing the purpose of the present invention, the technical scheme that the present invention adopts is:

A new type of lifting equipment, including a beam, cab, wire rope a, grab bucket, ladder, column legs, funnel, wheels, electromagnet, wire rope b, hoisting device, wire rope c, slide rail and platform, the beam is welded on On the column legs, the crossbeam picks out a certain distance from the column legs, and the bottom of the column legs is equipped with wheels. The wharf is equipped with guide rails for the crane wheels to walk on. The funnel is installed between the four column legs, and one of the column legs is equipped with a ladder. Welded on the top of the ladder; there is a slide rail in the middle of the beam, the cab is installed on the slide rail, the cab can slide back and forth on the slide rail, and a hoisting device is installed at the end of the beam, and a hoist and a differential are installed in the hoisting device. The wire rope c is led out from the hoisting device and connected to the cab; the wire rope a is led out from the hoisting device, passes through the pulley on the cab in the middle, and is connected to the grab at the end; one end of the wire rope b is connected to the hoisting device, and the other end Connected to the electromagnet, the ground on the dock is cast iron, and the electromagnet can attract the ground on the dock.

The advantages of the present invention are: the electromagnet hanging on the wire rope b is attracted to the ground on the wharf, so the crane can keep stable when lifting heavy objects, and no counterweight needs to be installed at the tail, so that it will not be damaged in typhoon days. It will be overturned by the strong wind, and it can also reduce the self-weight of the crane; when the crane needs to move its position, the electromagnet can be separated from the dock ground, which has the characteristics of convenient use and simple structure.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

A new type of lifting equipment, including beam 1, cab 2, wire rope a3, grab bucket 4, ladder 5, column legs 6, funnel 7, wheels 8, electromagnet 9, wire rope b10, hoisting device 11, wire rope c12, slide rail 13 and platform 14, the beam 1 is welded on the column leg 6, the beam 1 picks out the column leg 6 for a certain distance, the bottom of the column leg 6 is equipped with wheels 8, and the wharf is provided with a guide rail for the crane wheel 8 to walk, the whole crane The crane can move back and forth on the guide rail. The funnel 7 is installed between the four legs 6. The funnel 7 is used to transfer the minerals in the grab 4. One of the legs 6 of the crane is provided with a ladder 5, and the platform 14 is welded on the ladder. 5, the ladder 5 and the platform 14 are used for workers to go up and down the cab 2; a slide rail 13 is provided in the middle of the beam 1, and the cab 2 is installed on the slide rail 13, and the cab 2 can slide back and forth on the slide rail 13. The hoisting device 11 is installed, and the hoisting device 11 is provided with a hoist and a differential gear. The steel wire rope c12 is drawn from the hoisting device 11 to connect with the driver's cab 2, and the steel wire rope c12 can pull the driver's cab 2 to move back and forth on the guide rail; a3 is drawn from the hoisting device 11, passes through the pulley on the cab 2 in the middle, and is connected to the grab bucket 4 at the end. The wire rope a3 can lift the grab bucket 4, and the differential in the hoisting device 11 can make the cab 2 in Keep the grab bucket 4 at the same height during the movement; one end of the steel wire rope b10 is connected in the hoisting device 11, and the other end is connected on the electromagnet 9. The ground on the dock is cast iron, and the electromagnet 9 can be attracted to the ground on the dock. The crane is kept stable by the effect of electromagnet 9 attracting the wharf ground.

The use method of the present invention: firstly, the crane is installed on the wharf provided with cast iron on the ground. When the minerals on the cargo ship need to be unloaded, the worker enters the cab 2 through the ladder 5 and the platform 14, and the crane first moves to the side of the cargo ship through the wheels 8 , attract the electromagnet 9 to the ground of the dock, grab the minerals in the cargo ship through the grab bucket 4, then move the grab bucket 4 above the funnel 7, put the minerals in the grab bucket 4 into the grab bucket 4, below the funnel 7 Be provided with the conveyor belt of wharf, mineral is leaked to conveyor belt from funnel 7.
