Description

A light and simple gantry single girder crane

technical field

The utility model relates to a crane.

Background technique

Cranes are widely used in molds, auto repair factories, mines, construction sites and occasions that require lifting. Ordinary gantry cranes have complex structure, large volume, heavy weight, high friction, inflexibility, large bending moment at the rod end, and high energy consumption during use. The connection between the support arm and the crossbeam is unstable and prone to shaking.

Utility model content

The utility model solves the technical problems of complex structure, large volume, heavy weight, large friction, inflexibility, large bending moment at the rod end and high energy consumption during use of the crane. Therefore, the utility model provides a light simple gantry single girder crane, which has the advantages of simple structure, small size, light weight, small friction, flexible and effective release of rod end bending moment, and low energy consumption.

In order to achieve the above object, the utility model adopts the following technical solutions.

The utility model comprises a support arm, an oblique support arm, a connecting arm, a load-bearing beam, a beam, a connection fixing mechanism, a ground beam, a wheel, an electric appliance, an electric hoist, and the top of the support arm and the top of the oblique support arm are hinged with the beam; The upper end of the inclined support arm is connected with the connecting arm; the lower end of the support arm and the lower end of the inclined support arm are connected to the ground beam, and the load-bearing beam is installed under the cross beam; a connection and fixing mechanism is provided between the load-bearing beam and the support arm; wheels are installed on the ground beam; The electrical appliance is installed on the support arm; the electric hoist is installed on the load-bearing beam.

The connection and fixing mechanism of the utility model can be a rigging turnbuckle or a hinge rod.

A connecting and fixing mechanism for fastening is also provided between the load-bearing beam and the inclined support arm of the utility model.

The utility model has the advantages of simple structure and small volume. There are connecting and fixing mechanisms for reinforcement between the support arm and the beam, and between the inclined support arm and the beam. Compared with ordinary gantry cranes and cranes with V-shaped legs, it has light weight It has the characteristics of flexible installation and use, can effectively release the bending moment of the rod end, and has the advantages of low energy consumption.

The beneficial effect of the utility model: it has the characteristics of simple structure, small volume, light weight, small friction, flexible installation and use, can effectively release the bending moment of the rod end, and has the advantages of low energy consumption. The connection between the support arm and the beam is stable without shaking.
