Description

Technical Field

[0001] The invention relates to the field of engineering machinery, in particular to a device for split transportation of heavy and large drilling rigs. Background Art

[0002] Crawler drilling rigs are suitable for geological drilling in various places, and often need to be transported to other places. Traditional engineering machinery transportation requires the construction of a ramp for the transfer machinery to climb in the carriage of the transport vehicle, and various safety measures need to be taken to prevent the transfer machinery from overturning during the climbing process. This is time-consuming and labor-intensive, and various types of vehicle overturning accidents often occur, causing casualties and equipment damage. In particular, large crawler drilling rigs are heavy and have a high center of gravity. When loading and transferring using traditional methods, vehicle overturning accidents are more likely to occur; if a large crane is used for transportation, it is also labor-intensive and time-consuming, and the safety risk is high. Therefore, it is necessary to provide a device that can automatically load and unload crawler drilling rigs with strong safety and efficiency to improve loading and transportation efficiency.
