Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool accessories, in particular to an upper railing with stable positioning. Background Art

[0002] The sintering trolley is the main operating component of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine, receive the sintering mixed material in the upper horizontal section, and return to the head wheel after preheating, ignition, sintering, cooling, and turning over, forming a transmission cycle to achieve the purpose of sintering materials. The upper guardrail is one of the important components of the sintering trolley, and its main function is to prevent the processed materials from shifting.

[0003] The patent with patent application publication number 202111386781.9 discloses a sintering machine trolley guardrail with high wear resistance, which is used to improve the service life of the sintering machine trolley guardrail. Its technical solution is: the bottom surface of the upper guardrail has three dovetail sliding grooves, the axial direction of the three sliding grooves is perpendicular to the plate surface of the upper guardrail, the upper end surface of the lower guardrail has three sliders, the position and shape of the three sliders match the three sliding grooves of the upper guardrail, the sliders and the sliding grooves are tightly slidably matched, the three sliders and the three sliding grooves are respectively fixed by positioning pins, and the back of the upper guardrail and the lower guardrail is installed with a wear-resistant plate, the wear-resistant plate is composed of a low-carbon steel plate and an alloy wear-resistant layer, the wear-resistant plate is fixed to the back of the upper guardrail and the lower guardrail by bolts, and a sealing layer and a sealing strip are arranged between the wear-resistant plate and the upper guardrail and the lower guardrail. The present invention has a reasonable structure, is easy to use, and has good effects. It can avoid deformation, cracks, and gaps between the lower guardrail and the upper guardrail, thereby extending the service life of the guardrail area.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that the wear resistance of the sintering machine trolley is improved by setting protective plates such as wear-resistant plates, fireproof plates and reinforcing rib plates. However, when such protective plates are regularly repaired and replaced, the protective plates are usually removed by removing multiple sets of bolts, which is inconvenient for disassembly and assembly of the protective plates and increases the labor intensity of the staff. For this reason, we propose an upper railing with stable positioning. Utility Model Content
