Embodiment 1

[0026] Such as figure 1 Shown: a new type of reaming equipment, including a drill rod 1 and a drive motor 2 for driving the drill rod 1 to rotate, the drive motor 2 can be a servo motor; the upper end of the drill rod 1 is connected to the output shaft of the drive motor 2, The lower end of the drill rod 1 is provided with a guide bit 3, a reaming drill bit 4 and a support ring 5 from bottom to top, the guide drill 3 is installed on the lower end of the drill rod 1, the support ring 5 is coaxially arranged with the drill rod 1, and the support ring Several support rods 6 are arranged between the inner wall of 5 and the outer wall of drill pipe 1, combined with figure 2 As shown, in this embodiment, there are four support rods 6, which are evenly distributed along the circumference of the drill pipe 1, and the two ends of the support rods 6 are respectively welded on the drill pipe 1 and the support ring 5.

[0027] The hole reaming equipment also includes a casing 7, the cas...

Embodiment 2

[0036] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that: a handle 14 is provided on the top wall 702 of the housing, which is convenient for lifting and operating; a water tank 15 is provided in the chamber, and the water inlet of the water tank 15 and the guide sleeve 13 1032 are connected through water pipes, and the water injection port 16 on the side wall 701 of the housing is connected with the water tank 15; the box body of the water tank 15 is a metal plate, which can be made of copper plate. The metal plate has good thermal conductivity, absorbs heat and dissipates heat quickly, and the water in the water tank 15 can absorb the heat emitted by the driving motor 2, which helps to cool down and dissipate heat to the driving motor 2, avoids the excessive operating temperature of the driving motor 2, and improves its service life.

Embodiment 3

[0038] Such as Figure 4 As shown, the difference between the present embodiment and the second embodiment is that: the outer wall of the support ring 5 is provided with a number of evenly distributed protruding teeth 501, and the protruding teeth 501 can perform secondary repairs on the hole wall to make the well wall smoother; The outer wall of the ring 5 is provided with a number of diversion grooves 502 distributed along its circumferential direction, the length direction of the diversion grooves 502 is parallel to the axial direction of the support ring 5, and the arrangement of the diversion grooves 502 facilitates the discharge of mud generated during the reaming process. Sand gravel.

Abstract

The invention belongs to the technical field of geological prospecting equipment, and particularly discloses novel broadening equipment, including a drill rod and a drive motor used for driving the drill rod to rotate, one end of the drill rod, not connected with the drive motor, is provided in sequence with a guide drill bit, a broadening drill bit and supporting rings, the guide drill bit is arranged on the end portion of the drill rod, the supporting rings are coaxial with the drill rod, and a plurality of the supporting rods are installed between the internal wall of the supporting rings and the external wall of the drill rod. Broadening direction of the broadening drill bit is dragged and guided by the guide drill bit to keep concentric degree of the broadening direction and boreholedirection; the guide drill bit can break obstacles in front to avoid sticking of s drill due to collapse of holes in the process of broadening; the external wall of the guide drill ring makes contactwith the internal wall of boreholes, and when the drill rod rotates, the supporting rings matches the supporting rods to support the drill rod and avoid deviation of the drill rod, so that the concentricity of the boreholes after the broadening and boreholes of hole broadening gun is guaranteed, and the efficiency of the broadening is improved.

Description

technical field [0001] The invention belongs to the technical field of geological exploration equipment, and specifically discloses a novel hole reaming equipment. Background technique [0002] "Geological exploration" means to survey and detect the strata through various means and methods, determine the thickness of different strata, take core samples of rocks in different strata, and then determine the chemical and physical properties of rock minerals through testing and mechanical analysis. Drilling is the most widely used exploration method in engineering geological exploration. During the drilling process, the borehole needs to be reamed to increase the diameter of the borehole to facilitate the sampling of the experimenters. [0003] The reamer is a kind of reaming equipment commonly used in geological exploration. At present, the reaming equipment mainly consists of a drill pipe and a reamer bit fixed on the drill pipe. Due to the diameter of the reaming bit in the r...
