Description

Gantry crane motor equipment with stop device

Technical Field

The utility model relates to a motor equipment technical field specifically, relates to a gantry crane motor equipment with backstop device.

Background

The motor equipment is an indispensable component of the portal crane, is power for enabling the portal crane to perform lifting, amplitude variation, rotation, walking and other actions, and can not run without the motor portal crane. In a hoisting and amplitude changing mechanism of a gantry crane, a motor is mounted on a specially manufactured motor support, and then is connected with a speed reducer through a coupling or a floating shaft, the motor is connected with the motor support through 4 common bolts, according to the requirement of assembly standards, the diameter of a bolt hole is generally about 2 to 3mm larger than that of a bolt, if the motor is used for a long time, the bolt can be loosened due to load or shaking, if no stop exists, the motor can generate lateral displacement, so that an output shaft of the motor is not concentric with an input shaft of the speed reducer, after the allowable range is exceeded, the motor can generate extra load, the service life of the motor is influenced, on the other hand, the output shaft of the motor can be bent or broken due to long-time bending stress, and therefore, the conventional method is to weld two strip-shaped stop blocks on the left side and the right side of the motor, the stop blocks are generally in the size of length, width, height =100mm 30mm, and the four stop the motor from generating lateral displacement.

The conventional stopping device of the motor equipment of the gantry crane is adopted, the welding can be carried out only after the motor is aligned, the paint which is prepared on the motor support before can be damaged by the welding at the moment, and the time and the labor are wasted, and the later anticorrosion function can be influenced even if the paint is repainted on the welding place at the later stage; secondly, during welding, a certain extrusion effect on the motor can be generated, so that the prior alignment of the motor is not accurate any more, and the service life of the motor is influenced; and if the later stage has the problem of counterpoint and wants counterpoint adjustment again, can only cut the dog before and weld again, not only work load is big, influences the roughness of structure moreover. By adopting the stopping device of the conventional gantry crane motor equipment, in order to have enough space for welding the stop block on the motor support, the motor support needs to be widened by 100mm, the use amount of materials is increased, and the cost is greatly reduced.
