Technical Field

[0001] The present invention relates to the technical field of metal pipeline construction, and particularly relates to a fixing device. Background Art

[0002] A magnetic drill is a metal processing tool that adsorbs on steel structures for precise drilling, tapping, and reaming. During the construction of industrial metal pipelines, it is usually necessary to drill holes on metal pipelines of different sizes to install pipes, bosses, instrument parts, etc. After the metal pipeline is installed, the position of the drilled hole on the pipeline cannot be adjusted, and it is difficult to fix the magnetic drill as it easily slides on the pipeline surface; in addition, it is difficult to perform drilling operations on metal pipelines made of stainless steel and some special materials. The above problems have resulted in poor quality of metal pipeline drilling and low construction efficiency. Summary of the Invention

[0005] During installation, first place the base on the top of the metal pipeline, then use the chain to fix the base to the metal pipeline, and the chain is in a tensioned state after fixing; then, place the magnetic drill inside the base and use the locking device to fix the magnetic drill.

[0006] On the basis of the above solution, further, the locking device is four groups of positioning angle irons; the positioning angle irons are fixedly installed on the upper end surface of the base; each positioning angle iron is provided with a positioning bolt. Specifically, the positioning bolt is horizontally installed on the side wall of the positioning angle iron; the magnetic drill is placed inside the four groups of positioning angle irons, and the positioning bolt is rotated to lock the side wall of the magnetic drill base to fix the magnetic drill.

[0007] On the basis of the above solution, further, a V-shaped bracket is provided on the lower end surface of the base.

[0008] On the basis of the above solution, further, the chain is connected to the base through a hook and a pressing groove; the hook and the pressing groove are respectively located on opposite sides of the base; one end of the chain is connected to the hook, and the other end is pressed by the pressing groove.

[0009] Specifically, the pressing groove is composed of two U-shaped grooves inside and outside. Among them, the outer U-shaped groove is fixedly connected to the base. There is a through hole at the top of the outer U-shaped groove, and long bolt hole tubes are symmetrically arranged on the side walls of the outer U-shaped groove; there are internal threaded holes at the top of the inner U-shaped groove, and long holes are symmetrically arranged on the side walls of the inner U-shaped groove; the locking bolt passes through the through hole at the top of the outer U-shaped groove and is screwed into the internal threaded hole at the top of the inner U-shaped groove; the fixing bolt horizontally passes through the long bolt hole tube on the side wall of the outer U-shaped groove and the long hole on the side wall of the inner U-shaped groove, and the fixing nut is installed on the fixing bolt to fix the relative position of the fixing bolt and the outer U-shaped groove.

[0010] On the basis of the above solution, further, in order to realize the fine adjustment of the chain tension in the tensioned state, an adjusting nut is provided on the locking bolt.

[0011] In the above solution, specifically, the number of hooks and pressing grooves is two respectively. Each group of hooks and pressing grooves corresponds to a chain; the base is fixedly tied to the metal pipe through two chains.

[0012] During installation, one end of each chain is hung in the hook on the corresponding side of the base, and the other end passes through the bottom of the base and winds around the metal pipe, and then passes into the space between the inner U-shaped groove of the corresponding side pressing groove and the fixing bolt; then the chain is tightened so that the chain is in a tensioned state. By rotating the locking bolt, the locking bolt moves downward, and the locking bolt and the fixing bolt lock the chain. When it is necessary to fine-tune the chain tension, the position of the inner U-shaped groove can be adjusted up and down by screwing the adjusting nut. Finally, place the magnetic drill in the four locking devices on the base 1, and lock the side wall of the magnetic drill base by rotating the positioning bolt to fix the magnetic drill.

[0013] Beneficial effects: This device is applicable to drilling metal pipes of various specifications, sizes and materials, and can also position the magnetic drill to prevent it from sliding on the pipe surface, effectively improving the drilling efficiency and quality.
