Description
Technical Field
[0001] The utility model belongs to the field of petroleum drilling equipment, and specifically relates to a horizontal power catwalk machine. Background Art
[0002] At present, oilfield drilling operations are generally carried out on the drilling platform, and the drilling tools need to be lifted from the ground pipe rack to the drilling platform. Usually, a pneumatic winch or lifting system is used to drag one end of the pipe from the catwalk along the ramp to the operating platform. The conventional operation method requires multiple people to work together, which is labor-intensive and poses a safety hazard. In addition, the conventional dragging method causes the other end of the pipe to touch the ground, which is easy to wear the pipe in the process of moving the pipe up and down, and damage the pipe joint thread, causing the pipe to be scrapped. Although the power catwalk machine is gradually becoming popular in China, the current power catwalk machine mostly uses a lifting drill string delivery device, which requires the drill string and the entire drill string delivery device to be lifted to the height of the drilling platform. During the operation, the catwalk machine has poor stability and there is a risk of the drill string slipping. Utility Model Content
