Abstract

The invention relates to a crane mechanical transmission device without a power source in the working area, which is characterized in that it includes a bridge frame, a lifting transmission mechanism, a crane running transmission mechanism and a trolley running transmission mechanism; The first lifting gear pair, the second lifting transmission shaft, and the second lifting gear pair; the crane running transmission mechanism includes: the crane running screw and the screw nut; the trolley running transmission mechanism includes: the trolley running transmission shaft, the trolley running transmission gear pair 1. The screw nut that the trolley running screw is fixed to the crane trolley. The advantages are: it solves the corrosion and radiation of corrosive gases and radioactive substances on the electrical system of the crane, and avoids damage to the electrical system. In addition, the device can satisfy the use function of the crane in special occasions, reduces the failure rate of equipment, is convenient for maintenance, and improves safety.

Description

Technical field [0001] The invention belongs to the technical field of crane manufacturing, and particularly relates to a crane mechanical transmission device without a power source in a working area. Background technique [0002] At present, cranes are widely used in nuclear power, military industry, metallurgy, machinery, chemical industry, petroleum energy and other fields. In special occasions, there are corrosive gases or radioactive substances in the use environment. Because many corrosive gases and radioactive substances are extremely harmful to radiation, electrical equipment is extremely easy to damage. For the above reasons, the electrical parts, wires, cables, and motors of the crane must be placed outside the above environment to ensure the normal operation of the crane. Therefore, the crane working in the above-mentioned conditions needs to be equipped with corresponding mechanical transmission devices. Summary of the invention [0003] In order to solve the technica...
