Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a power head installation structure and a drilling rig. Background Art

[0002] At present, for large-diameter deep-hole mining drilling and coalbed methane exploration above 450mm, drilling rigs can only perform positive pressure positive circulation operations, and cannot perform gas lift reverse circulation operations. They cannot perform drilling operations and drilling work in ultra-complex formations such as aquifers, goafs, caving areas, caves, loose formations, etc., and cannot meet the requirements of rapid drilling in complex formations.

[0003] According to the existing market demand, in order to meet the drilling operations and exploration work in ultra-complex formations, it is considered to add a set of power heads (external power heads) that can be used for large-diameter deep holes of 450mm or more to conventional drilling rigs, that is, drilling rigs that can only be equipped with a single power head (internal power head). During normal routine operations, the equipped internal power head can realize conventional drilling operations such as conventional coalbed methane, geothermal, water wells, and oil exploration and development. When encountering ultra-complex formations such as the above-mentioned aquifers, goafs, caving areas, caves, and loose formations, a large-diameter external power head can be used for dual-power head and pipe drilling operations, thereby achieving the rapid drilling requirements of complex formations; at the same time, in order to ensure that the equipment transportation complies with national road regulations and the weight and height of the entire machine cannot be increased, the additionally installed external power head must meet the requirements of quick disassembly and assembly.

[0004] Therefore, there is an urgent need for a power head mounting structure and a drilling rig that can realize the rapid disassembly and assembly of the external power head and the lifting function of the external power head. Utility Model Content

[0012] The telescopic end of the lifting oil cylinder passes through the sliding frame from top to bottom, the cylinder barrel is connected to the end surface of the sliding frame close to the mast operating platform, and the telescopic end is connected to the mast operating platform through a support.

[0013] As a further improvement of the above scheme, the sliding frame includes a support frame, two track clips and two clip connectors. The track clips are arranged on both sides of the support frame through the clip connectors, and the two track clips are symmetrically arranged about the center of the support frame so that the sliding frame can be slidably mounted on the track plate.

[0014] As a further improvement of the above solution, the cross section of the track clamp is L-shaped.

[0015] As a further improvement of the above solution, the support frame includes a bottom plate, two side plates vertically arranged on the bottom plate, and a cover plate;

[0016] The two side plates are spaced apart and arranged in parallel on the bottom plate, and the cover plate is arranged on the upper ends of the two side plates and forms a mounting through hole for the lifting cylinder to pass through;

[0017] It also includes a cylinder mounting plate, which is blocked at one end of the mounting through hole and is used for fixed installation with the cylinder of the lifting cylinder.

[0018] As a further improvement of the above solution, the cover plate is provided with a plurality of power head mounting holes, and the connecting plate of the power head is fastened to the cover plate by bolts.

[0019] As a further improvement of the above solution, a wear-resistant plate is further provided between the sliding frame and the track plate.
