Description

Mounting tool for clamp spring of sealing gasket of rotary joint

Technical Field

The utility model relates to a metallurgical machinery rotary joint mounting tool, concretely relates to sealed jump ring mounting tool that fills up of rotary joint in fan-shaped section roller bearing frame of continuous casting.

Background

The continuous casting fan-shaped section roller often has the problem of water leakage after running for a period of time, and through disassembly and inspection, the water leakage point is mainly concentrated on the damage of a silicon carbide sealing gasket of a rotary joint arranged on a roller bearing seat. And the silicon carbide sealing gasket is fixed in the groove by a clamp spring, and the clamp spring clamp cannot be used due to the large difficulty in disassembling the bearing and the bottom depth of 15cm, so that the installation difficulty is high, and great difficulty is caused in repairing equipment.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defect of the prior art, the utility model provides a sealed jump ring mounting tool that fills up of rotary joint, this mounting tool need not demolish the bearing and need not use jump ring pincers, can realize the installation to the sealed jump ring that fills up of rotary joint.

The technical scheme is as follows: a mounting tool for a clamp spring of a sealing gasket of a rotary joint comprises a sealing gasket fixing device and a clamp spring pressing device; the sealing gasket fixing device comprises a sleeve, wherein a pressing surface for pressing the circumferential flange of the sealing gasket is formed on the front end surface of the sleeve; the clamp spring pressing device comprises a piston, the piston is coaxially arranged in the sleeve and can move along the axial direction of the sleeve, and the front end face of the piston is provided with a circular concave part and an annular boss which is formed around the concave part and used for pressing the clamp spring.

Specifically, the recessed portion is disposed coaxially with the sleeve. Thereby ensuring that the centering is convenient during installation.

The diameter of the concave part is not smaller than the outer diameter of the convex part of the rotary joint sealing gasket, and the diameter of the concave part is smaller than the outer diameter of the clamp spring. On one hand, the concave part can be ensured to surround the convex part of the sealing gasket, and the interference of the convex part during installation is avoided; on the other hand, the diameter of the concave part is smaller than the outer diameter of the clamp spring, so that the annular boss can be pressed on the clamp spring, and the installation is guaranteed to be in place.

The depth of the recessed portion is not less than the height of the raised portion of the rotary joint seal. Therefore, when the piston is pressed to the bottom, the convex part of the sealing gasket can be accommodated in the concave part, and the installation in place is guaranteed.

The sealing gasket fixing device further comprises first handles, and the first handles are symmetrically arranged on two sides of the sleeve. Thereby facilitating handheld operation.

The clamp spring pressing device further comprises a piston rod and a second handle, the piston rod is coaxially connected to the rear end of the piston, and the second handle is connected to the piston rod.

Has the advantages that: the mounting tool for the clamping spring of the rotary joint sealing gasket can be used for mounting the silicon carbide sealing gasket of the rotary joint in the continuous casting fan-shaped section roller bearing seat without dismounting the bearing and using clamping spring pliers. The repair efficiency is improved, the sealing effect of the rotary joint is guaranteed, the water leakage condition of the rotary joint in the operation process of the roller is guaranteed, the service cycle of the roller is prolonged, and the internal quality of a casting blank is indirectly improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses an installation tool is the sealed jump ring installation that fills up of carborundum for continuous casting fan-shaped section roller bearing frame internal rotation joint, as shown in figure 6, figure 7, should fill up to seal up and fasten in the bearing through the jump ring.

As shown in fig. 1-5, the mounting tool is welded by using a steel structure, and mainly comprises a sealing gasket fixing device 1 and a clamp spring pressing device 2, wherein the two parts can be separated and combined.

Specifically, the sealing gasket fixing device 1 includes a sleeve 11 and first handles 12 installed on both sides of the sleeve 11, the sleeve 11 is a circular sleeve, and the diameter thereof may be made with reference to the inner diameter of the bearing in order to ensure the centering when installing. When in use, the front end surface of the sleeve 11 presses against the circumferential flange of the silicon carbide gasket to fix the gasket.

The clamp spring pressing device 2 comprises a piston 21, a piston rod 22 and a second handle 23, wherein the piston 21 is coaxially arranged in the sleeve 11, is attached to the inner wall of the sleeve 11 and moves along the axial direction of the sleeve, and ensures that the clamp spring is centered in place. The front end surface of the piston 21 has a circular recessed portion and an annular boss formed around the recessed portion for pressing the circlip. Of course, to ensure centering, the circular recess is also arranged coaxially with the sleeve 11.

The annular boss compresses the clamp spring on the silicon carbide sealing gasket by pushing the piston 21. The diameter of the concave portion is larger than the outer diameter and depth of the convex portion of the sealing pad, so that the convex portion is prevented from being pressed. The circlip is directly installed in place.
