Abstract

The utility model relates to a lifting mechanism of a gantry crane. The lifting mechanism comprises a body and a lifting appliance, both the body and the lifting appliance are provided with pulley blocks, the body is fixed on a main beam, a steel wire rope led out from the body is connected onto the pulley block on the lifting appliance via the pulley block on the body, the body is further provided with a motor, and the motor drives the steel wire rope to move. The lifting mechanism adopts an electric winch to replace a traditional hydraulic winch, and reduces cost and is simpler in installation and maintenance of equipment on the premise of keeping safety factors of the winch unchanged.

Description

Gantry crane lifting mechanism

technical field

The utility model relates to the technical field of container hoisting equipment, in particular to a gantry hoisting mechanism.

Background technique

Aiming at the shortcoming that the electric hoist winch commonly used in the domestic market is easy to generate electric sparks, a hydraulically driven winch is used in the lifting mechanism of the gantry crane. Due to the reduction of components that generate electrical sparks, the winch with hydraulic transmission has strong safety, good reliability, stable operation, and convenient installation and use. However, the cost of adopting this transmission mode is very high, and the installation and maintenance are very troublesome, which needs to be improved.

Utility model content

The technical problem to be solved by the utility model is to provide an improved gantry crane lifting mechanism in order to solve the problems existing in the existing gantry crane lifting mechanism in the above-mentioned background technology.

The technical solution adopted by the utility model to solve the technical problems is: a gantry hoisting mechanism, including a body and a spreader, the body and the spreader are provided with pulley blocks, the body is fixed on the main beam, and the body The steel wire rope drawn from the center is connected to the pulley block on the sling through the pulley block on the body, and the body is also provided with a motor to drive the wire rope movement. The electric winch is steplessly regulated by the frequency converter, which can make the four winches move synchronously or independently to realize lifting or lowering.

The beneficial effect of the utility model is that the utility model adopts an electric winch instead of a traditional hydraulic winch, and on the premise that the safety factor of the winch remains unchanged, the cost is reduced and the installation and maintenance of the equipment are simpler.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

The embodiment of the gantry crane lifting mechanism of the present invention as shown in Figure 1, comprises body 1 and spreader 2, is provided with block pulley 3 on body 1 and spreader 2, and described body 1 is fixed on the main girder 4, The wire rope 5 drawn from the body 1 is connected to the pulley block 3 on the spreader 2 through the pulley block 3 on the body 1, and the motor 6 is also arranged on the body 1 to drive the wire rope 5 to move. The stepless speed regulation of the device can make the four winches move synchronously or independently to realize lifting or lowering.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
