Embodiment 1

[0010] This embodiment provides a tie rod in the tuyere, the structure is as follows figure 1 and figure 2 As shown, the double-arm parallel pull rod composed of two pull rods 1 has a hook 2 at the front end of the double-arm parallel pull rod, and fastening bolts 3 are installed at the ends of the two pull rods to adjust the opening and closing degree of the front-end hook; the front end of the double-arm parallel pull rod The direction of the hook is turned inside out.

[0011] In this embodiment, the single-arm pull rod of the tuyere small sleeve is optimally designed as a double-arm parallel pull rod, and fastening bolts are installed at the ends of the two parallel double-arm pull rods. There will no longer be a slipping phenomenon of the pull rod during the middle sleeve, and the time for pulling down the middle sleeve is greatly shortened.

Abstract

The invention relates to a pull rod for an air vent middle sleeve. The pull rod for the air vent middle sleeve comprises a pull rod, wherein the pull rod is a double-arm parallel pull rod formed by two pull rods; a hanger is arranged at the front end of the double-arm parallel pull rod; fastening bolts are arranged at the tail ends of the two pull rods for adjusting the openness of the hanger at the front end. The pull rod can save the dismounting time by shortening the time for dismounting a middle sleeve from about 40 minutes to about 10 minutes and reduces the pull rod slip phenomenon and potential safety hazards; moreover, damping down caused by the faults of the middle sleeve is shorted, thereby reducing damping down delay and improving the production efficiency.

Description

technical field [0001] The invention relates to a maintenance tool for a tuyere in front of a furnace, in particular to a pull rod with a sleeve in the tuyere. Background technique [0002] The middle sleeve of the tuyere in front of the furnace was replaced after failure. In the past, there was no special tool, and only a small set of tie rods could be used. It took 40 minutes to replace a middle sleeve, and the use of a small set of tie rods was prone to slipping due to the wrong size, which affected the replacement time. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a tool that can conveniently replace the sealing sleeve, which has the characteristics of time saving and simple operation. [0004] In order to solve the above technical problems, the present invention provides a pull rod in the tuyere, including a pull rod, the pull rod is a double-arm parallel pu...
