Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of non-ferrous metal smelting equipment, and particularly relates to a PS converter poking air hole machine drill rod fixing device. BACKGROUND

[0002] In the converter blowing process, air is sent into the converter through the air supply system to react with the melt in the furnace to realize slagging and copper making; in the blowing process of the converter, in order to ensure the air volume required for blowing operation, the prerequisite is to ensure the air supply area, so the air hole needs to have sufficient area; the function of the poking air hole machine is to clean the bonding material bonded near the air hole with a steel drill to ensure that the air supply system and the furnace body are connected with the air pipe; therefore, the poking air hole machine reduces the labor intensity of personnel, improves the air supply volume and blowing time, and ensures the efficient and continuous air supply of the converter.

[0003] The drill rod port of the original drill rod seat is directly above, in the use process of the poking air hole machine, the position of the air hole and the position of the drill rod are not in the same plane, or the bonding is serious and the drill is stuck, the drill is ejected from the air hole machine clamp seat, and this happens very frequently, causing the drill rod to fall into the safety pit and cannot be picked up in time, and the drill rod can only be picked up during the shutdown and maintenance, many of which have been deformed and cannot be used normally, resulting in waste of the drill rod. UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the above problems and provides a PS converter poking air hole machine drill rod fixing device.

[0005] To solve the above technical problems, the utility model adopts the technical scheme that:

[0006] A PS converter poking air hole machine drill rod fixing device, comprising a base and a clamp seat, the base is fixed on the poking air hole machine through a plurality of bolts, the clamp seat is fixedly arranged on the middle of the front face of the base, and the base and the clamp seat are integrally cast, a rectangular clamping groove is formed in the middle of the clamp seat, the lower end face of the clamping groove is an arc face, a clamping edge is arranged around the clamping groove on the front face of the clamp seat, the front face around the arc clamping groove is an arc clamping edge, an "L" shaped access groove is formed in the left side wall of the upper part of the clamp seat, and a top plate is arranged on the upper end face of the clamp seat.

[0007] Further, the drill rod head of the drill rod is a circular plate, the width of the clamping groove is greater than the diameter of the drill rod head, the width of the clamping edge and the diameter of the arc clamping edge are less than the diameter of the drill rod head, and the diameter of the clamping edge and the arc clamping edge is greater than the diameter of the drill rod.

[0008] Further, the width of the lower part of the access groove is greater than the diameter of the drill rod head, and the width of the upper part of the access groove is greater than the diameter of the drill rod.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1. The utility model discloses a slot is arranged on the lateral wall, and the top surface is equipped with the top plate, can effectively prevent the drill rod is bounced out, and the edge and arc edge can card the drill rod head, make the drill rod fixed.

[0011] 2. The utility model discloses simple structure, easy operation, low in cost. DRAWINGS
