Chain connecting plate for traveling chain of blast furnace tapping machine trolley

Abstract

The invention provides a chain connecting plate for a traveling chain of a blast furnace tapping machine trolley, which is integrally of a symmetrical structure in a cuboid form. Comprising a chaining hole formed in the center of the cuboid, a chain plate groove formed in the middle of the end of each side of the cuboid, two bosses located on the two sides of the chain plate groove and located on the end of each side of the cuboid, and a pin shaft hole concentrically penetrating through the two bosses on the end of each side of the cuboid. According to the connecting plate, the pin shaft penetrating through the pin shaft hole is evenly stressed, original middle single-side stress is changed into four-point stress, bending stress borne by the pin shaft and the pin shaft hole is converted into tensile stress, the borne tensile stress is evenly distributed on the pin shaft and the pin shaft hole, and therefore the problems that the pin shaft is bent and the pin shaft hole is torn are effectively solved; fault points are eliminated, the fault rate is reduced, and the operation efficiency of blast furnace molten iron discharging is improved.

Description

technical field [0001] The invention belongs to the technical field of blast furnace front equipment, and in particular relates to a link plate for a traveling chain of a trolley of a blast furnace shedding machine. Background technique [0002] Blast furnace tapping machine is the main equipment for tapping molten iron in blast furnace. Whether its operation is reliable or not plays a vital role in the smelting capacity of blast furnace, the quality of molten iron and the smooth running of blast furnace. The rock drill is the main part of the opening machine. The rock drilling machine is fixed under the trolley of the drilling machine by bolts. The trolley of the drilling machine is hung on the walking guide rail of the beam of the drilling machine with wheels. The trolley of the drilling machine is pulled forward by the hydraulic motor fixed on the beam through the walking chain. Or back, so as to drive the rock drill fixed on the tapping machine trolley to move to open th...

AI Technical Summary

Problems solved by technology

The main problem of the link in the prior art is that during use, the pin used to link the link and the chain is only stressed on one side in the middle, and the uneven force is easy to break the pin or break the pin. The pin holes at both ends are torn, and the failure rate is high, which affects the working efficiency of blast furnace molten iron
