Coil cable bracket device and limit control method of tractor for molten iron tank under blast furnace

Abstract

The application provides a cable winding bracket device and a limit control method for a tractor of a molten iron tank under a blast furnace, and relates to the technical field of tractor operation control. The device includes a supporting bracket assembly structure and an adjusting bracket structure. The support bracket combination structure includes a support rod and a bracket, the support rod is used to connect the steel rail, the bracket is connected with the support rod and can be used to support the winding cable, and the adjustment bracket structure includes an adjustment frame, a limiter and a contact block, and the adjustment frame It is used to connect the tractor, the limiter is arranged on the adjustment frame, the contact block is arranged on the support rod, and the tractor brakes when the limiter cooperates with the contact block. The bracket can be used to support the coiled cable, and the coiled cable can be used for initial positioning. Due to the supporting function of the bracket, the coiled cable will not be damaged. Further, when the limiter cooperates with the contact block, it can be The secondary limit ensures that the operation of the tractor can indeed stop within the safe range, and prevents the tractor from exceeding the specified range of travel. Prevent production accidents caused by out-of-range operation.

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
