AI Technical Summary

Problems solved by technology

[0007] 2. Large fluctuations in production conditions
[0008] Sintering or roasting production is a process of continuous air extraction (supply), combustion, and heat exchange. Long-term shutdown will change the production conditions and cause large fluctuations in production conditions.
[0009] 3. Affect product quality
But this must stop the operation of the sintering machine, and online replacement cannot be realized

Embodiment 1

[0071] Example 1, such as Figure 1~Figure 12 shown.

[0072] The trolley replacement device consists of trolley 30, inner straight rail 5, 8, inner curved rail 3, outer straight rail 4, 7, outer curved rail 20, main drive wheel 6, trolley moving out of rail 9, trolley moving into rail 2 and so on.

[0073] Inner straight rails (5, 8) and inner curved rails (3) form inner guide rails; outer straight rails (4, 7) and outer curved rails (20) form outer guide rails; main drive wheels ( 6), the gear of the main drive wheel (6) is located between the inner guide rail and the outer guide rail;

[0074] Outer curved rail 20 is installed on the both sides of main drive wheel 6, is made up of bottom movable outer curved rail 202, middle part fixed outer curved rail 203, top movable outer curved rail 201 etc.

[0075] The lower movable outer curved rail 202 is a partial ring structure, and two round holes are provided at both ends to cooperate with the guide rod 401. The lower movabl...

Embodiment 2

[0081] Example 2, Figure 13 shown.

[0082] This embodiment is a change carried out on the basis of Embodiment 1, the difference is:

[0083] 1. Simplify the upper movable outer curved rail 201 in Embodiment 1, cancel the rail II2012, become a single rail and lengthen the rail I2011, and install the weight 2013 directly on the rail I2011.

[0084] 2. At the lower right corner of the movable outer curved rail 201, a circular arc step matching the shape of the inner curved rail 3 is provided.

[0085]

[0086] For the rest, it is the same as Example 1, and reference may be made to this specification and the relevant descriptions of Example 1.

Abstract

The invention relates to a trolley changing device and a trolley changing method, and belongs to the technical field of changing of sintering machines in the metallurgical industry and belt type roasting machine trolleys. The trolley changing device comprises a trolley, inner straight tracks, inner bent tracks, outer straight tracks, outer bent tracks, a main transmission wheel, a trolley moving-out track and a trolley moving-in track, wherein each of the outer bent tracks on two sides of the main transmission wheel is divided into a lower movable outer bent track, a middle fixed outer bent track and an upper movable outer bent track; the lower movable outer bent tracks on the left side and the right side of the running direction of the trolley are outwards separated from the middle fixed outer bent tracks and the lower outer straight tracks; and one ends of the upper movable outer bent tracks are hinged to one end of the trolley moving-in track. By the trolley changing device, the trolley can be changed under the condition that a sintering machine or a belt type roasting machine is not stopped, extra trolley changing time is not required, and the production efficiency is improved; because the sintering machine or the belt roasting machine is not stopped and air blowing reduction or air blowing stopping is not carried out, production conditions are not changed and are stable relatively; and moreover, because the production conditions are stable, the product qualification ratio and the drum index are not reduced.

Description

technical field [0001] The invention relates to a trolley replacement device and method, and belongs to the technical field of trolley replacement for sintering machines and belt roasting machines in the metallurgical industry. Background technique [0002] The grate bars and wheel bearings on the trolley of the sintering machine or belt roasting machine are easily damaged. If the damage is to a certain extent, the faulty trolley must be hoisted out as a whole to replace or repair the grate bars and wheel bearings. enter. [0003] The replacement and installation positions of the existing sintering machine trolley are at the middle tail of the sintering machine and the top of the bellows, and the replacement and installation positions of the belt roaster are at the head of the belt roaster and the top of the bellows. Taking the sintering machine as an example, when the faulty trolley is replaced, the material distribution device stops feeding, the faulty trolley and the tro...
