This utility model discloses an underground pipeline repair device, including a remote-controlled vehicle that moves inside the pipeline and a storage tank for storing repair fluid. The remote-controlled vehicle is equipped with a leveling mechanism, which includes: a fixed frame with a main leveling roller mounted on it, the fixed frame being installed at the bottom of the remote-controlled vehicle; two auxiliary leveling rollers, each connected to the fixed frame via a drive assembly; and a power assembly connected to the two drive assemblies. This utility model has a simple structure. A single power assembly drives two drive assemblies to adjust their angles, thereby simultaneously adjusting the angles of the two auxiliary leveling rollers connected to the drive assemblies. This allows the main and auxiliary leveling rollers to better adapt to pipelines of different sizes. As the fit between the main and auxiliary leveling rollers and the bottom of the pipeline inner wall increases, the repair fluid can be leveled more effectively, allowing it to flow more fully into the pipeline gaps and improving the repair effect.

The utility model provides a long -life high -performance screw tip tap has the coarse handle handle, thin neck and screw tip of coaxial connection as an organic whole, the chip flute made of screw tip is three groove structure, and the chip flute of three groove structure is three equal parts distribution relative to tap center axis, and the chip flute groove shape is two straight lines two circular arc form, and the smooth transition between circular arc, the screw tip still is made with straight flute, and the screw tip tap adopts the high -speed steel material of vacuum heat treatment, cryogenic treatment and passivation treatment to make. The utility model solves how to reach the technical problem of high -efficient tapping processing of high -performance screw tip tap product on numerical control equipment, improves tap life, processing high -efficient, quality is stable, long -lived, is fit for promotion.
