Problems solved by technology

[0006] 2. Large fluctuations in production conditions
[0007] 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.
[0008] 3. Affect product quality
But this must stop the operation of the sintering machine, and online replacement cannot be realized

Embodiment 1

[0069] Example 1, such as Figure 1~Figure 11 shown.

[0070] A trolley replacement device, consisting of trolley 30, inner straight rails 5, 8, inner curved rail 3, outer straight rails 4, 7, outer curved rail 20, main drive wheel 6, trolley moving out of rail 9, trolley moving in Track 2 and so on.

[0071] 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;

[0072] 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.

[0073] The upper end of the lower movable outer curved rail 202 is hinged with the lower end of the middle fixed outer curved rail 203. At the hinged position, the thickness...

Embodiment 2

[0078] Example 2, Figure 12 shown.

[0079] This embodiment is a change carried out on the basis of Embodiment 1, the difference is:

[0080] 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.

[0081] 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.

[0082] 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 belongs to the technical fields of trolley changing of metallurgical industry sintering machines and belt type roasting machines. The device comprises a trolley, an inner straight rail, an inner curved rail, an outer straight rail, an outer curved rail, a main transmission wheel, a trolley moving-out rail and a trolley moving-in rail. The outer curved rail on two sides of the main transmission wheel are segmented into a lower movable outer curved rail, a middle fixed outer curved rail and an upper movable outer curved rail; the upper end of the lower movable outer curved rail is hinged to the lower end of the middle fixed outer curved rail, and one end of the upper movable outer curved rail is hinged to one end of the trolley moving-in rail. By the aid of the device, the trolley of the sintering machine or belt type roasting machine can be changed without shutdown, the additional trolley changing time can be omitted, and producing efficiency is improved; the shutdown and blowing reducing or stopping operations of the sintering machine or belt type roasting machine are avoided, and the producing state is unchanged and is stable correspondingly; since the production condition is stable, the product qualifying rate and drum revolving index are not decreased.

Description

technical field [0001] The invention relates to a trolley replacement device and method, belonging to the technical field of trolley replacement for sintering machines and belt roasting machines in the metallurgical industry. Background technique [0002] 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 trolleys before and after it are empty, and the faulty trolley with empty material generally runs to the proper position at the tail, the sintering machine stops running, and the hydraulic pressure is started. The push rod moves the rear mobile frame back to loosen the adjacent trolle...
