SU123491A1 - Device for loosening the tapered connection of a crown with a pant with a connector - Google Patents

Description

Devices are known for loosening the tapered connection of the rod with the crown and for their separation, using an element worn on the cylindrical end of the crown, subject to impact.

The insulated device differs from the known ones in that it is made in the form of a hammer that acts on the connection of the crown with the rod through an intermediate head and is held relatively to the crown with the help of a female crown of a bracket rigidly connected to the hammer. Such an embodiment of the device significantly increases the intensity of the impact on the conical connection of the crown with the rod and accelerates the operation of the connector.

The drawing depicts the described device. The device consists of an air hammer /, an intermediate striker 2, a sleeve 3 and a bracket 4 screwed onto the barrel of the impact mechanism. A riveting hammer with spool air distribution was used as a pneumatic hammer.

When the crown is removed, the device is put on the cylindrical part of the crown with a staple, and then the shock is turned on. The piston of the hammer is striking the intermediate striker, through which they are transmitted to the crown held relative to the hammer by the clamp. When the cone joint is loosened between the drill rod and the crown, the brake is removed from the rod;

Subject invention

A device for loosening a tapered connection of a crown with a barbell at a connector using blows applied to a cylindrical

The end part of the crown, characterized in that, in order to exert an intensive influence on the conical connection of the crown with the rod, the device is designed as an impact hammer, acting on the connection of the crown with the shtanga through the intermediate block and held relative to the crown, which is rigidly connected to the hammer.
