Crane Control Method Suitable for Cold Regions

Abstract

The invention discloses a crane control method applicable to cold areas, which can be used for effectively removing ice on a rail by pre-heating the rail. The crane control method particularly comprises the following steps: collecting multi-point temperature data dispersed on the rail and sending the data to a computer; calculating an average temperature value by the computer; judging when the average temperature value is lower than a heating threshold value, controlling a heating device distributed on the rail to heat; acquiring the multi-point temperature data on the rail by the computer and calculating an average temperature; judging when the average temperature value is higher than a normal working threshold value, controlling the heating device to stop heating; and starting an automatic loading / unloading flow. According to the crane control method applicable to the cold areas, the rail can be automatically subjected to temperature detection and is heated before loading / unloading so that the whole rail has no ice and the smooth driving of a trolley is guaranteed; the abrasion between the rail and the trolley is alleviated; the maintenance rate is reduced and the whole service life of a crane is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automatic control of cranes, in particular to a control method for cranes suitable for cold regions. Background technique [0002] Cranes are widely used in various industrial productions, and different types of cranes are used according to the goods to be transported and different environments. In the cold north, especially in the port, the running track of the trolley of the crane is often icy. When the trolley is started to move, it is easy to cause rapid wear of the track and the trolley. The maintenance frequency is high, and the service life of the crane is seriously affected. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a crane control method suitable for cold areas, which can effectively eliminate ice slag on the track by preheating the track. [0004] In order to achieve the above object, the present invention provides the following t...
