Hydraulic energy-saving drill pipe transportation equipment

Abstract

The invention discloses hydraulic energy-saving drill pipe transportation equipment comprising a base, a lifting module, a rod feeding module and an energy-saving module. The lifting module is hinged to the base through a lifting supporting shaft, one end of a lifting oil cylinder in the lifting module is hinged to the base, and the other end of the lifting oil cylinder is hinged to the middle portion of a lifting lower support. The rod feeding module is hinged to a lifting upper support and a movable sliding sleeve through a mechanism. A box in the energy-saving module is fixedly connected with the base. The lifting supporting shaft and a gear supporting shaft are connected through a coupling. By means of an energy-saving mechanism, energy consumption is reduced and the energy-saving effect is achieved. During lifting, stretching of the supports is finished, manual operation is reduced, safety risks are reduced, and drill pipe transportation efficiency is improved. Only a support telescopic oil cylinder can achieve stretching of the lifting supports and pushing of a drill pipe. The ellipsograph principle is used in the rod feeding mechanism, parallel pushing of the drill pipe is guaranteed, the structure is simplified, and the hydraulic energy-saving drill pipe transportation equipment has the advantages of being low in production cost and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for oil drilling rigs, and in particular relates to a hydraulic energy-saving drill pipe conveying equipment. Background technique [0002] At present, the transportation of drill pipes on land oil drilling rigs at home and abroad is basically completed by ground equipment, and the degree of automation of the transportation equipment plays a decisive role in the efficiency of drill pipe transportation. At present, the automation degree of most drill pipe conveying equipment in China is insufficient. It takes a long time to convey drill pipe and the efficiency is low. At the same time, the labor intensity of the workers is high, and there are potential safety hazards. Either the structure is complex or the manufacturing cost is high, which affects the replacement of catwalk equipment. Moreover, the current catwalk equipment consumes a lot of energy, and the recovery and reuse of the gr...

At present, the automation degree of most drill pipe conveying equipment in China is insufficient. It takes a long time to convey drill pipe and the efficiency is low. At the same time, the labor intensity of the workers is high, and there are potential safety hazards. Either the structure is complex or the manufacturing cost is high, which affects the replacement of catwalk equipment. Moreover, the current catwalk equipment consumes a lot of energy, and the recovery and reuse of the gravitational potential energy of the equipment during the return journey is not considered.
