Description
Technical Field
The utility model belongs to the technical field of blast furnace repair tools, concretely relates to quick fastener of blast furnace tuyere belly pipe.
Background
The blast furnace is a main device for smelting pig iron, a blast furnace tuyere consists of a tuyere large sleeve, a tuyere middle sleeve and a tuyere small sleeve, and a belly pipe is fixed with the small sleeve through a pull rod bolt. In the actual production of the blast furnace, the blast furnace and the accessory equipment thereof are extremely easy to burn out under the high-strength work, so that the contact between the belly pipe and the concave-convex matching surface of the small sleeve is not compact, and the air leakage of the air port is caused. In order to ensure the stable operation of the blast furnace equipment, the blast furnace and the accessory equipment thereof need to be overhauled regularly. The tuyere belly pipe of large-scale blast furnace is because its weight and structural position limit, at the in-process of changing blast furnace tuyere belly pipe, 8 connecting bolt's fastening is very troublesome, will consume a large amount of manpowers, and is consuming time longer, still has the phenomenon that probably appears causing the workman to hurt because of the sledgehammer misuse simultaneously. In conclusion, how to solve the problems of low efficiency and high labor intensity of the dismounting operation of the tuyere belly pipe of the blast furnace becomes a technical problem which needs to be solved urgently by technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
To the deficiency of the prior art, the utility model aims to provide a quick fastener of blast furnace tuyere belly pipe, the device simple structure, application scope is wide.
A quick fastening device for a blast furnace tuyere belly pipe comprises a clamping mechanism, a hydraulic oil way, a pressure gauge and a hydraulic oil pump, wherein the clamping mechanism is of a concave shape, a jack lying on one side is arranged at an opening of the clamping mechanism, the telescopic end of the jack is aligned to the other end of the opening, the jack is connected with the hydraulic oil pump through the hydraulic oil way, and the pressure gauge is arranged on the hydraulic oil way.
The lifting jack is a small 30-ton hydraulic lifting jack.
As an improvement, the gap between the flanges on the tuyere belly pipe of the blast furnace exceeds 5 mm.
As an improvement, the clamping mechanism is formed in one step.
The improvement is that the connecting pipe of the hydraulic oil pump and the jack is a rubber pipe, and the working pressure of the pressure gauge is 30-50 MPa.
Has the advantages that:
compared with the prior art, the utility model relates to a quick fastener of blast furnace tuyere belly pipe, simple structure, through the fastening flange of jack, reduces maintenance personal, has enlarged user's scope, even women's maintainer also can realize the fastening operation. The hydraulic oil pump realizes fastening, ensures uniform fastening torque, shortens maintenance time and has good field use effect. The device simple structure, convenient to carry, it is efficient, be applicable to the fastening of all kinds of belly pipes.
