Embodiment Construction

[0011] Such as figure 1 As shown, a gantry type drilling rig verticality adjustment device includes a base 1, an adjustable support foot 2 is installed at the four corners of the base 1, and a pair of vertical rods 3 are installed symmetrically on both sides of the base 1. The rod 3 is perpendicular to the base 1. The vertical rod 3 is provided with a guide rail 4, and a sliding block 5 is arranged between the two guide rails 4. The sliding block 5 can slide up and down on the two guide rails 4, and a motor 6 is arranged in the middle of the sliding block 5. The output shaft of 6 is used to connect with a drill rod, and a through hole 7 is opened in the middle of the base 1 through which the drill rod can pass.

[0012] The tops of the two vertical rods 3 are connected by a connecting rod 8. The base 1 is made of steel plate.

[0013] Before drilling, adjust the adjustable support foot 2 and use a level to detect the base 1 to level. Because the vertical rod 3 and the base 1 rem...

Abstract

The invention discloses a perpendicularity adjusting device for a portal frame type drilling machine. The device comprises a base, the four corners of the lower portion of the base are each provided with an adjustable supporting leg, and a pair of vertical rods are symmetrically mounted on the two sides of the upper portion of the base; the vertical rods are perpendicular to the base, guiding rails are arranged on the vertical rods, a sliding block is arranged between the two guiding rails and can slide on the two guiding rails in the up-down direction, and an electric motor is arranged in the middle of the sliding block; and an output shaft of the electric motor is used for being connected with a drilling rod, a through hole is formed in the middle of the base, and the drilling rod can penetrate through the through hole. In use, by adjusting the adjustable supporting legs to enable the base to be horizontal, adjustment of the perpendicularity of the drilling rod is achieved; by continuously adjusting the perpendicularity of the drilling rod in the hole drilling process, the phenomenon that a drill bit damages a PE pipe of an adjacent well position is avoided, so that protection of a formed well hole is facilitated; and the device is low in manufacturing cost, obvious in effect and capable of being repeatedly used.

Description

Technical field [0001] The invention belongs to the field of gantry type drilling rigs, and specifically relates to a verticality adjustment device of a gantry type drilling rig. Background technique [0002] In the construction process of ground source heat pump drilling, when the gantry drilling rig is used for construction, the distance between adjacent well positions is 4.5m to 5m, and the well depth is 125m. In two adjacent well positions, if the relative verticality deviation of the drill pipe is 2%-3% during drilling, stringing may occur during the drilling operation, and the drill bit will damage the PE pipe of the adjacent well. Thus causing quality accidents. Summary of the invention [0003] The purpose of the present invention is to provide a verticality adjusting device for a gantry type drilling rig, which is used to solve the verticality problem of drill rods. [0004] In order to achieve the above objective, the technical solution adopted by the present invention i...
