Abstract
A blast furnace tapping machine drilling rod belong to mechanical equipment technical field, be equipped with the drilling rod body, drilling rod body one end is equipped with the screw thread of connection openings machine, the other end is equipped with the screw thread of connecting the drill bit, the characteristic sets up one to take over a business on the body, take over a business the screw thread department of setting at the connection openings machine, taking over a business the diameter and being greater than the diameter of drilling rod body, the shape of taking over a business is in circular, oval, the polygon one kind. Making one in threaded connection's part and taking over a business, make blast furnace tapping machine drilling rod threaded connection part strength increase, blast furnace tapping machine drilling rod withstands tapping machine at the during operation, takes over a business tightly to link together through the screw thread with tapping machine, and tapping machine drilling rod the threaded portion just is difficult to the rupture. The beneficial effects of the utility model are that: making the strength increase of blast furnace tapping machine drilling rod threaded connection part, being difficult to the rupture in during operation blast furnace tapping machine drilling rod threaded connection part, blast furnace tapping machine can normal work.
Description
Technical field
This utility model belongs to mechanical equipment technical field, particularly relates to a kind of tap-hole bar of blast furnace.
Background technology
Tap-hole bar of blast furnace is to be made by the seamless steel pipe of certain specification, and its technique is for connecting the screw thread of tapping machine and drill bit on the two ends of seamless steel pipe process, as shown in Figure 1. One end connects tapping machine as in figure 2 it is shown, one end connects drill bit in use, and tapping machine rotates rapping and drives tapping machine drilling rod to rotate rapping. Owing to the strength of tapping machine is very big, causing the power suffered by tapping machine drilling rod also just very big, the power that one end of connection tapping machine is subject to is maximum. And tapping machine two ends of drill has the screw thread of processing, the local steel pipe walls of processing screw thread is just thin, and when big active force, threaded portion is easy for fractureing, and causes that tap hole of blast furnace cannot normal operation.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problem, it is provided that a kind of tap-hole bar of blast furnace, local reinforcing threaded for tap-hole bar of blast furnace, solves the problem that tap-hole bar of blast furnace easily snaps off.
In order to solve the problems referred to above the technical solution adopted in the utility model it is: a kind of tap-hole bar of blast furnace, it is provided with drilling rod body, drilling rod body one end is provided with the screw thread connecting tapping machine, the other end is provided with the screw thread connecting drill bit, it is characterized by that arranging one on body takes over a business, described take over a business to be arranged on the screw thread place connecting tapping machine, described in take over a business the diameter diameter more than drilling rod body, the shape taken over a business is a kind of in circular, oval, polygon. Make one in threaded part to take over a business, making the threaded part intensity of tap-hole bar of blast furnace increase, tap-hole bar of blast furnace operationally, withstands tapping machine, taking over a business with tapping machine by together with screw thread is tightly coupled, tapping machine drill rod thread part is just not easy to fracture.
The invention has the beneficial effects as follows: making the intensity of the threaded part of tap-hole bar of blast furnace increase, operationally the threaded part of tap-hole bar of blast furnace is not easy to fracture, blast furnace opening function normal operation.

1 drilling rod body, 2 tapping machines, 3 screw threads, 4 take over a business.
Detailed description of the invention
Further this utility model is illustrated below in conjunction with the drawings and specific embodiments;
Embodiment 1: as shown in Figure 3-4, a kind of tap-hole bar of blast furnace, it is provided with drilling rod body 1, drilling rod body 1 one end is provided with the screw thread 3 connecting tapping machine, the other end be provided with connect drill bit screw thread, body arranges one and takes over a business 4, described in take over a business 4 be arranged on connect tapping machine screw thread 3 places, described take over a business 4 diameters more than the diameter of drilling rod body 1, the shape taking over a business 4 is circular. 4 tapping machine 2 is withstood with taking over a business on this utility model blast furnace drilling rod, make with tapping machine 2 by together with screw thread is tightly coupled, power suffered by threaded portion is by taking over a business to undertake, the intensity of such tap-hole bar of blast furnace threaded portion also just improves a lot, tap-hole bar of blast furnace is not easy to fracture, and also just can work normally.
Embodiment 2, a kind of tap-hole bar of blast furnace, it is provided with drilling rod body 1, drilling rod body 1 one end is provided with the screw thread connecting tapping machine, the other end is provided with the screw thread connecting drill bit, body arranges one take over a business, described take over a business to be arranged on the screw thread place connecting tapping machine, described in take over a business the diameter diameter more than drilling rod body 1, the shape taken over a business is oval.
Embodiment 3, a kind of tap-hole bar of blast furnace, it is provided with drilling rod body 1, drilling rod body 1 one end is provided with the screw thread connecting tapping machine, the other end is provided with the screw thread connecting drill bit, body arranges one take over a business, described take over a business be arranged on connect tapping machine screw thread place, described in take over a business the diameter diameter more than drilling rod body 1, the shape taken over a business is polygon.
The foregoing is only detailed description of the invention of the present utility model, for a person skilled in the art, this utility model can have various change, all any amendments made within spirit of the present utility model and principle, and replace improvement etc., all should include within the right that this is novel.
