Embodiment 1

[0018] refer to Figure 1-Figure 2 , a sintering machine tail star wheel tooth plate top trolley detection and protection device provided in this embodiment includes an arc detection plate 1 made of a 3mm thick steel plate, and the arc detection plate 1 is installed on the sintering The tail star wheel 10 is directly above the horizontal rails on both sides of the mobile frame 11 at the rear of the machine, wherein the arc detection plate 1 tail star wheel 10 inlet end adopts a circular arc or a knuckle bend transition, and the other end is straight. A gap of 25 ± 5 mm is reserved between the straight section of the curved detection board and the highest point of the rim of the platform wheel 12 for installation, and the end of the curved detection board 1 is connected with the turning hinge 2 . The flip hinge 2 is installed on the side wall plate of the moving frame at the tail of the sintering machine. The top of the vertical connecting rod 3 faces the moving frame 11 at th...

Embodiment 2

[0020] The structure of the detection and protection device for the top trolley of the star wheel tooth plate at the tail of the sintering machine provided by this embodiment is the same as that of the embodiment, the only difference is that the straight section of the arc-shaped detection plate and the highest point of the rim of the platform wheel 12 are reserved for 30±5mm Clearance installation.

[0021] The working process of the above-mentioned sintering machine tail star wheel tooth plate top trolley detection and protection device is as follows: the jacking amount of the platform wheel 12 is preset in the programmable PLC controller to be 30mm, and the sintering machine is running and detected by the distance measuring radar 9 The height lift after the rim of the platform wheel 12 contacts the arc detection plate 1, the distance measuring radar 9 transmits the height lift signal to the programmable PLC controller, and the programmable PLC controller compares the height ...

Abstract

The invention discloses a detection and protection device for a sintering machine tail star wheel toothed plate top trolley. The device comprises an arc-shaped detection plate, the arc-shaped detection plate is installed at the star wheel entering position over horizontal rails on the two sides of a sintering machine tail swing frame, and the gap of 25 + / -5 mm or 30 + / -5 mm is reserved between the straight plate section of the arc-shaped detection plate and the highest point of a wheel rim of a trolley wheel. The end part of the arc-shaped detection plate is connected with an overturning hinge. The overturning hinge is installed on a side wall plate of a sintering machine tail moving frame, a lower vertical connecting rod is hinged to the upper portion of the arc-shaped detection plate, the side, facing the sintering machine tail moving frame, of the top of the lower vertical connecting rod is hinged to one end of a horizontal connecting rod, a universal rotating support is arranged in the middle of the horizontal connecting rod, and an upper vertical connecting rod is hinged to the other end of the horizontal connecting rod. A limiting sleeve is arranged on the periphery of the middle section of the upper vertical connecting rod, a reference measuring plate is horizontally installed on the top of the upper vertical connecting rod, and a ranging radar is arranged on the top of the reference measuring plate. The device can prevent a tail star wheel toothed plate from jacking up the trolley and clamping a tail bent rail head, and the condition of shutdown caused by production accidents is completely eliminated.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a detection and protection device for a sintering machine tail star gear tooth plate top trolley. Background technique [0002] Belt sintering machine is widely used in the iron and steel metallurgy industry for sintering and smelting of iron concentrate powder, and is the most critical process equipment in the smelting and sintering process. It consists of a number of trolleys connected end to end to move forward, arranged on the upper and lower layers of parallel tracks, and the upper and lower tracks are connected to form a closed loop of running tracks through the head and tail curved rails. The active star wheel is installed on the curved rail of the machine head to drive the trolley forward, and the passive star wheel is installed on the curved rail of the tail. All the above components are installed on the mobile frame, and the tension of the mobile frame is realized...
