Problems solved by technology

[0004] First, the rotary drilling rig using the above-mentioned goose head structure technology cannot achieve multiple stepless adjustments to the center distance of the drilling hole, and there are limitations in construction;
[0005] Second, when the rotary drilling rig is being transported, the transportation height is reduced by turning the whole goose head down, but the space required after the whole goose head is turned down is still large, which is not conducive to transportation

Abstract

The invention discloses a foldable goose head structure with infinitely adjustable drilling center distance, belonging to the technical field of rotary drilling rigs. The proximal end of the main pulley frame I is rotatably mounted on the base, and the distal end of the main pulley frame I is hinged with a connecting rod I; II is hinged with connecting rod I; a variable center distance oil cylinder is hinged between the main pulley frame II and the base, and a posture maintaining cylinder is hinged between the main pulley frame II and the connecting rod II; the proximal end of the auxiliary pulley frame I is rotated and installed on the main pulley frame II. On the pulley frame I, a swinging oil cylinder of the auxiliary goose head frame is hinged between the auxiliary pulley frame I and the main pulley frame I. The invention finally realizes the stepless adjustment of the drilling center distance of the rotary drilling rig through the telescopic driving of the main pulley frame II of the variable center distance oil cylinder to swing back and forth. The goose head structure reaches the minimum in the front, rear, left and right directions, reducing the occupied space and meeting the transportation requirements.

Description

technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to a foldable goose head structure with infinitely adjustable drilling center distance. Background technique [0002] The current goose head structure is mainly a fixed center distance goose head structure, that is, the main goose head pulley frame is an integrated fixed structure. Such a structure can only meet the construction requirements of a rotary drilling rig to achieve a drilling center distance. There is also a goose head frame with a set of spare pulley holes added in construction machinery, which can meet the construction requirements of rotary drilling rigs to achieve two drilling center distances; [0003] The above technology has the following problems: [0004] First, the rotary drilling rig using the above-mentioned goose head structure technology cannot achieve a variety of infinitely adjustable drilling center distances, and there are limitations in c...
