Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, specifically to a device for changing sintering machine trolleys. Background Technology

[0002] Currently, online replacement of sintering machine trolleys in China generally adopts a crane-mounted replacement method. This method requires manual assistance, and during the replacement process, the trolleys carrying a large amount of sintered ore and other materials cannot be controlled due to uncontrolled dust pollution. Furthermore, the materials on the replaced trolleys cannot be disposed of all at once. Since the replacement is primarily carried out at the tail end of the sintering machine, the high ore temperature poses a risk of burns. Additionally, the main exhaust fan runs continuously during online replacement, resulting in wasted electricity. Some companies have optimized the trolley replacement process to a return operation on the sintering machine, but this is constrained by on-site equipment and requires a large amount of auxiliary equipment, resulting in significant investment.

[0003] This utility model provides an online device and method for changing sintering machine trolleys. A power-driven trolley changing device moves laterally at the head of the sintering machine, automatically moving the trolley to be replaced and the spare trolley into position. This eliminates the environmental problems and burns associated with changing trolleys at the tail of the sintering machine. The replaced trolleys have no material accumulation, the entire system operates automatically without manual assistance, and safety hazards are eliminated.

[0004] This application enables online replacement of sintering machine trolleys, which can be achieved by modifying old sintering machines. The replacement position is convenient, there are no environmental or dust problems, it occupies little space, and reduces the number of personnel required for on-site operation. It will not affect the working efficiency of the sintering machine, and can reduce the risk of on-site accidents to a certain extent. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, the sintering machine trolley replacement device structure provided by the present invention is such that the sintering trolley replacement device 4 is arranged at the head of the sintering machine and is set on the frame 5 of the sintering machine. The sintering machine trolley 2 enters the horizontal track 3 of the sintering machine from the bend 1 at the head of the sintering machine and runs along the horizontal track 3 of the sintering machine to the trolley replacement device 4 and onto the horizontal track 10 of the trolley replacement device.

[0021] The horizontal rails 10 of the trolley changing device are set on both sides of the trolley changing device 4 and are at the same height and level as the horizontal rails 3 of the sintering machine.

[0022] like Figure 2 As shown, the sintering machine trolley changing device structure provided by the present invention includes a trolley changing device 4 installed on a trolley changing device transverse track 9, and the trolley changing device transverse track 9 installed on a sintering machine frame 5.

[0023] The spare trolley running track 12 is at the same height and level as the sintering machine horizontal track 3, and the width of the spare trolley running track 12 is the same as that of the sintering machine horizontal track 3, which ensures the safe operation of the sintering machine trolley 2 and the spare trolley 13.

[0024] The operation method of the trolley changing device 4 is as follows:

[0025] When the sintering machine trolley 2 that needs to be replaced touches the horizontal limit 6 of the sintering machine trolley replacement device, the sintering machine system stops. The sintering machine trolley check device 7 pops out, fixing the trolley in front of the sintering machine trolley 2 that needs to be replaced, preventing the trolley from rotating and affecting the operation of the trolley replacement device 4.

[0026] The sintering machine trolley changing device 4 is equipped with a trolley changing device electric horizontal propulsion system 8 at the bottom. The trolley changing device electric horizontal propulsion system 8 can realize forward and reverse operation, and propel the trolley changing device 4 to run on the trolley changing device horizontal track 9.

[0027] When the sintering machine trolley 2 that needs to be replaced runs to the trolley replacement device 4 and is in place, the sintering machine stops, and the electric horizontal drive system 8 of the trolley replacement device starts to drive the trolley replacement device 4 to run forward toward the spare trolley 13.

[0028] When the trolley changing device 4 touches the trolley changing device positioning limit 15, the trolley changing device electric lateral drive system 8 stops operating.

[0029] The backup trolley electric propulsion system 14 propels the backup trolley 13 to run on the backup trolley running track 12, and the backup trolley 13 propels the sintering machine trolley 2 on the trolley changing device 4.

[0030] When the standby trolley 13 touches the standby trolley positioning limit 16 and the sintering machine trolley 2 touches the sintering machine replacement trolley positioning limit 17, the standby trolley electric drive system 14 stops running. At this time, the standby trolley 13 runs and stops on the trolley replacement device 4.

[0031] After the spare trolley 13 is parked stably on the trolley changing device 4, the electric lateral drive system 8 of the trolley changing device is started to run in reverse. When the trolley changing device 4 touches the lateral positioning limit 11 of the trolley changing device, the electric lateral drive system 8 of the trolley changing device stops running.

[0032] The entire automatic sintering machine trolley replacement system has been completed, and the sintering machine system has been started.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
