The present disclosure relates to a drilling machine. More particularly, the present disclosure relates to a method of autonomously positioning the drilling machine in a shipping configuration.
In drilling and other work sites, various drilling vehicles, i.e. mobile drilling machines, are used. The drilling vehicle is provided with a boom and a drilling work machine on the boom. The boom is moved during use between different working positions. Controlling the boom is typically a demanding and time-consuming task, because the boom structure is complex. The boom usually comprises multiple boom actuators and joints the setting of which to a desired position using manual controls is not always intuitive. Furthermore, visibility of the operator to a working site may be poor and available free space is limited.
Typically, at a drilling site using such drilling vehicles, shipping containers are used to transport the drilling vehicles from one location to another. For the drilling vehicle to adequately fit inside the shipping container, the drilling vehicle needs to be within a maximum permissible shipping width, length & height. Exceeding the permitted dimensions may attract financial penalties, therefore it is vital for the drilling machine to be within a shipping envelope. For moving the drilling vehicle from any operating configuration to the shipping configuration, an operator may need to follow various sequential steps so that various front-end implements of the drilling vehicle are within the shipping envelope. Further, the operator needs to avoid any surrounding obstacles, or operator cabin etc. while following such steps making the process highly critical and tedious.
U.S. Pat. No. 9,476,256 (hereinafter called as the '256 reference) discloses a mining vehicle and a method of moving a boom of a mining vehicle. The boom is provided with several boom joints and there is a mining work device at a distal end of the boom. One or more boom joint positions are determined and stored in a memory medium. A control unit of the mining vehicle may automatically move the boom to a predetermined tramming position. Tramming position is defined as a configuration of the mining vehicle to efficiently travel between two mining locations. However, the '256 reference does not disclose about a shipping configuration and problems associated with the same.
Thus, there is a need to provide a drilling vehicle which may be stowed to a shipping configuration efficiently.
