Embodiment 1

[0085] like Figure 1 to Figure 4 As shown, the reaming device of the present embodiment includes: a drive shaft 1 driven by a motor to rotate, and two groups of grinding mechanisms; two groups of grinding mechanisms include a first grinding mechanism 2 and a second grinding mechanism 3; each group The grinding mechanism includes two grinding blades, and the grinding blades are strip-shaped iron sheets;

[0086] The drive shaft 1 is provided with a shaft key 101; the bottom end of the drive shaft 1 is provided with a fixed plate 102, and the fixed plate 102 is fixedly connected with the drive shaft 1; the fixed plate 102 is disc-shaped, which is perpendicular to and coaxial with the drive shaft 1;

[0087] The first grinding mechanism 2 includes two curved first grinding blades 201 and a first sliding disc 202; the first sliding disc 202 is slidably sleeved on the drive shaft 1; corresponding to the shaft key 101, the first A sliding plate 202 is provided with a keyway 203; t...

Embodiment 2

[0092] The difference between this embodiment and Embodiment 1 is that the reaming device further includes a third grinding mechanism, the third grinding mechanism includes two curved third grinding blades and a third sliding disk; the third sliding The disk is slidably sleeved on the drive shaft; corresponding to the shaft key, a keyway is provided on the third sliding disk; two third grinding blades are arranged symmetrically at a distance of 180°; one end of each third grinding blade is connected to The fixed plate is fixedly connected, and the other end is fixedly connected with the third sliding plate; the third sliding plate is located above the second sliding plate. The grinding blades of the same group are located on different planes.

Embodiment 3

[0094] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the side of the first sliding plate is provided with at least one (for example four) threaded grooves 206 for debris discharge, and the bottom of the threaded grooves 206 is deep , shallow above, and its length is less than one circle. The second sliding plate is provided with four notches 305 for debris to pass through, and the positions of the notches 305 correspond to the grooves 206 on the first sliding plate.

Abstract

The invention belongs to the field of reaming of fixing the electric-power line in building construction, and relates to a fixation method for the electric-power line in the building construction. The fixation method comprises the following steps that 1 drilling is conducted, and a slim hole is formed; 2 a reaming device is arranged in the slim hole, a motor is started, reaming is conducted, and a rough hole is formed; 3 a threaded rod is inserted into the rough formed in the step 2; 4 cement mortar or concrete is put in the rough hole formed in the step 2; 5 the cement mortar or concrete which are put in the step 4 is solidified; 6 the electric-power line is fixed on the threaded rod. The fixation method for the electric-power line in the building construction has the advantages that the operation is simple, and a pear-shaped hole can be drilled to fix the electric-power line.

Description

technical field [0001] The invention relates to a hole reaming device and a hole reaming method, in particular to a power line fixing method for building construction. Background technique [0002] Reaming is the enlargement of the bottom of a borehole or of some types of foundation piers in order to increase the load-carrying area. It is a method used to increase the inner diameter of a perforated workpiece such as a tube, cup, or shell. [0003] Due to structural or aesthetic considerations, pear-shaped holes are sometimes required in actual processing. [0004] Chinese patent application 200910209002.0 discloses a rotary reamer, which consists of a cylinder, a rotating device, a mud scraping device, and a coupling sleeve. The mud scraping device is set at the front end of the rotating device; the coupling sleeve is fixed at the rear end of the rotating device; there is a convex ring on the inner wall of the cylinder, and an internal thread is provided on the convex ring...
