Description

Technical Field

[0001] The invention belongs to the field of metallurgical cranes, and in particular relates to a metallurgical crane sliding wire automatic oxidized iron scale blowing structure and a metallurgical crane. Background Art

[0002] The iron adding and steel tapping spans in the converter workshop are easily affected by the workshop process environment during the production process, and iron oxide scale is easily generated. This iron oxide scale is dispersed inside the workshop and easily deposited on the upper part of the crane slideway.

[0003] This deposition phenomenon poses a potential threat to the segmented insulation wood, which may cause creepage and arcing, and thus pose a major hidden danger to the safe production and operation of the workshop. At the same time, due to the particularity of the workshop production process environment, even if it is improved through measures such as optimizing dust removal, it is still impossible to completely eliminate the generation of iron oxide scale, and this hidden danger continues to exist. Therefore, it is difficult to fundamentally solve the problem by relying solely on existing improvement measures.

[0004] In order to effectively deal with this situation, some converter workshops have begun to manually clean the scale at the crane sliding line and other locations regularly, and through regular purging and other management measures, the deposition problem can be alleviated in a short time and the hidden dangers can be reduced. However, the manual regular cleaning method not only requires long-term effective management and maintenance, but also has problems such as high labor intensity and low work efficiency. Summary of the invention

[0005] The purpose of the present invention is to propose and design a metallurgical crane sliding line automatic purging iron oxide scale structure and a metallurgical crane in order to solve the problem that iron oxide scale is easily deposited on the sliding line of the crane in the existing converter workshop, and enable the structure to move along with the trolley walkway of the metallurgical crane during the movement of the metallurgical crane to achieve continuous purging of the sliding line, thereby ensuring that there is no dust accumulation on the upper part of the crane sliding line and preventing the occurrence of creepage arcing due to the deposition of iron oxide scale on the segmented insulating wood.

[0006] In order to achieve the above-mentioned purpose, the present invention provides, on one hand, a structure for automatically blowing away the scale oxide on the sliding line of a metallurgical crane, which includes a fixed bracket, one end of which is provided with a crane fixing part, which is fixedly mounted on the trolley platform of the metallurgical crane; the other end of the fixed bracket is provided with a fan mounting part, which is equipped with a purge fan, which is located above the crane sliding line, and the air outlet of the purge fan is arranged opposite to the crane sliding line. At this time, when the metallurgical crane is moving, it can synchronously drive the purge fan to move, and continuously purge the crane sliding line part during the movement of the purge fan, so as to clean up the scale oxide, dust accumulation, etc. at the crane sliding line, and avoid the creepage arc phenomenon of the segmented insulation wood at this place due to the deposition of scale oxide.

[0007] Furthermore, the controller of the purge fan is electrically interconnected with the travel control module of the metallurgical crane, so that when the driver controls the metallurgical crane to travel, he can synchronously control the opening of the purge fan through the electrical interconnection structure between the purge fan and the metallurgical crane to achieve continuous purge of the crane slide line.

[0008] Furthermore, the purge fan is an axial flow fan.

[0009] Furthermore, the fixed bracket includes a bracket 1 and a bracket 2, one end of the bracket 1 is a crane fixing part, one end of the bracket 2 is a fan installation part, and one end of the bracket 1 away from the crane fixing part is detachably connected to the bracket 2. At this time, since the fixed bracket in the present invention adopts a split structure in which the bracket 1 and the bracket 2 are detachably connected together, it can adjust the installation position of the purge fan by adjusting the relative position relationship between the bracket 1 and the bracket 2, thereby ensuring that the blowing direction of the purge fan can correspond to the position of the crane sliding line.

[0010] Furthermore, a central mounting hole is provided on the end of the first bracket away from the fixing part of the crane, and the outer circle of the central mounting hole has at least two auxiliary mounting holes in an array with the central mounting hole as the center circumference; a central connecting hole and an auxiliary connecting hole are provided on the second bracket, and the second bracket can be detachably mounted on the first bracket by means of fasteners that penetrate the central connecting hole and the central mounting hole at the same time, and fasteners that penetrate the auxiliary connecting hole and the corresponding auxiliary mounting hole at the same time, and the angle between the second bracket and the first bracket can be flexibly adjusted by selecting the auxiliary mounting holes at different positions, so as to achieve the purpose of adjusting the blowing direction of the purge fan.

[0011] Furthermore, bracket 2 is provided with at least two rows of fan fixing holes along the length direction, and a fan base is fixedly installed at the end of the purge fan. The fan base is detachably mounted on bracket 2 by fasteners penetrating the corresponding row of fan fixing holes.

[0012] Furthermore, the fastener is a bolt.

[0013] On the other hand, the present invention further provides a metallurgical crane, which comprises a crane body, wherein the crane body is provided with the above-mentioned metallurgical crane sliding line automatic iron oxide scale blowing structure.

[0014] It can be seen from the above technical scheme that the present invention has the following advantages: when the existing metallurgical crane is equipped with the present invention, it can synchronously drive the purge fan to move during the walking process of the metallurgical crane, and continuously purge the crane sliding line part during the movement of the purge fan, thereby cleaning up the iron oxide scale, dust accumulation, etc. at the crane sliding line, avoiding the creepage arc phenomenon due to the deposition of iron oxide scale in the segmented insulating wood at this location.
