Embodiment 1

[0031] A down-the-hole drilling rig for breaking through pilot holes in granite road cuttings

[0032] In this embodiment, the specifications and technical requirements of each component are as follows:

[0033] 1) Support frame: Weld a 30mm thick steel plate with a DN51 steel pipe, pass through another DN45mm steel pipe with a pin and connect it to the drill stand.

[0034] 2) The connecting plate between the support frame and the drilling frame: it is processed by a 40mm thick steel plate and welded on the drilling frame.

[0035] 3), jack: according to image 3 The relevant dimensions are checked and calculated by the design institute, processed by relevant manufacturers, and welded together with the drill stand.

[0036] 4) Drill stand: 20a I-beam and 30mm thick steel plate are used for assembly and welding.

[0037] 5) Telescopic rod: ￠30mm round steel is used, and the two ends are processed into ￠20mm threaded buttons, a total of 2 pieces.

[0038] 6) Sliding plate: ...

Embodiment 2

[0052] A method for using a down-the-hole drilling machine for breaking through pilot holes in granite road cuttings, characterized in that it includes the following steps:

[0053] a. Assemble the down-the-hole drilling rig, wherein the installation of the drill pipe, impactor and drill bit should be completed by stretching the jack rod after the air compressor works.

[0054] b. The drill frame and the support frame can be freely adjusted according to the actual situation of the construction site; the drill bit 10, the impactor 9, and the drill pipe 8 are connected in sequence, and the principle of lifting up and down is that the jack 5 is connected with the sliding plate 6, and the sliding plate 6 is connected with the drill Frame 1 and telescopic rod 2 are connected to form a propulsion mechanism. Compressed air enters the cylinder through the pipeline to act on the piston, and the piston rod drives the slide plate through the bracket to perform rock drilling.

Abstract

A downhole drill for granite cutting guide hole breaking comprises a drilling rack, a rotation motor, a drill rod, a controller and an air compressor, and is characterized in that the drill rack (1) is a rectangular frame, a connecting plate (3) and a supporting rack (4) welded at the two ends above one side of the rectangular frame are connected through bolts; the rotation motor (7) is connected with a sliding plate (6) through a side surface of a connecting flange base; one end of the drill rod (8) is vertically mounted on a connecting flange at the bottom of the rotation motor (7), the other end of the drill rod is connected with an impacter (9) which is further connected with a drill bit (10); one end of the controller (12) is connected with the air compressor (11) through an air tube, and the other end of the controller is connected with the connecting flange of the rotation motor (7) through the air tube and is also connected with a jack (5) through an impacter (9) head; the mobile screw air compressor (11) is connected with the jack and the controller through the air tube.

Description

technical field [0001] The invention relates to a down-the-hole drilling machine, in particular to a down-the-hole drilling machine used for piercing guide holes in granite road cuttings and a use method thereof. Background technique [0002] During the burial of pipelines in municipal engineering, some stone areas (granite) are often encountered in special areas, whose hardness is unimaginable, so this obstacle needs to be broken. Explosive blasting is usually used in general routines. Chinese patent CN101793486A disclosed a blasting construction technology for high-grade road stone cuttings on August 4, 2010. The stone cuttings are blasting construction methods, but in densely populated and numerous buildings Not feasible in a municipal environment. At present, a double-knife mining quarry machine is used for cutting in the demolition process. Due to the large size of the equipment, numerous auxiliary equipment, and difficulty in moving, it often takes a lot of time and m...
