Coiled cable bracket device for molten iron tank tractor under blast furnace and limiting control method

Abstract

The invention provides a coiled cable bracket device for a molten iron tank tractor under a blast furnace and a limiting control method, and relates to the technical field of tractor operation control. The device comprises a supporting bracket combined structure and an adjusting bracket structure, wherein the supporting bracket combined structure comprises a supporting rod and a bracket; the supporting rod is used for being connected to a steel rail; the bracket is connected to the supporting rod and can be used for bearing a coiled cable; the adjusting bracket structure comprises an adjustingframe, a limiting stopper and a contact gear, wherein the adjusting frame is used for being connected to a tractor, and the limiting stopper is arranged on the adjusting frame; the contact gear is arranged on the supporting rod; and while the limiter is matched with the contact gear, the tractor brakes. the bracket can be used for supporting the coiled cable, so that initial limiting is conductedthrough the coiled cable; and due to supporting effect of the bracket, the coiled cable cannot be damaged. Furthermore, when the limiter is matched with the contact gear, secondary limiting can be conducted, so that operation of the tractor can be guaranteed to be stopped within the safety range indeed, and thus, the tractor is prevented from exceeding the specified stroke range. And production accidents caused by out-of-range operation are prevented.

Description

technical field [0001] The present application relates to the technical field of tractor operation control, and in particular, relates to a coiling cable bracket device and a limit control method of a tractor for a molten iron tank under a blast furnace. Background technique [0002] The iron ladle tank tractor used in metallurgical enterprises is used in the alignment of the blast furnace, and the coiled cable connection method is adopted. When the tractor is running forward, the coiled cable is unfolded along the direction of the railway, and when the tractor is running backwards, the coiled cable is retracted. The tractor uses alignment to set a certain running distance. Therefore, along the running range of the tractor, it is necessary to set up a protective bracket for the coiled cable to be unfolded and lifted to prevent the coiled cable from adhering to the ground and foreign objects from damaging the coiled cable. Since the tractor is connected by a coiled cable, the...

AI Technical Summary

Problems solved by technology

Since the tractor is connected by a coiled cable, the running distance is limited. It is also extremely important to prevent the tractor from driving out of the operating range. Calculate the length and distance of the coiled cable to limit the position and control the running distance of the tractor. The alignment of the tractor under the blast furnace is extremely demanding. Once the limit fails, the tractor will drive out of the operating range and cause unpredictable accidents. The cable is broken, the circuit is short-circuited, and the electrical equipment is damaged. In severe cases, the tractor drives into the taphole, causing a major accident in which the molten iron burns the tractor.

[0003] Therefore, the separate control of the cable travel limiter cannot ensure the safe operation of the tractor's operating range, and there is a risk that the cable travel limiter will fail and the tractor will drive out of the operating range
