Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sintering machines, in particular to an automatic replacement device for grate bars of a sintering machine trolley. Background Art
[0002] The sintering machine is the main equipment of the sintering production process. Whether it can operate normally directly affects the stability of the entire production process. Due to the large number of sintering machine trolleys on the sintering machine, the complex structure of the components and the relatively harsh operating conditions, the high temperature generated by the sintering machine can easily cause the trolleys to block the grate bars. Once the grate bar blocking phenomenon is formed, the air permeability of the area will deteriorate sharply, and the local over-humidification phenomenon will become more serious, further aggravating the formation of the grate bar blocking phenomenon, and finally until the trolleys are blocked, causing some trolleys to lose air permeability, resulting in the sintering process cannot proceed normally.
[0003] In the related technologies, most of them are improved from the structure of the grate bars or the sintering machine trolley itself to increase the service life of the grate bars. However, after long-term use, the grate bars will become blocked and manual inspection is required. This method consumes a lot of manpower and material resources and it is difficult to detect the loosening or falling of individual grate bars in time, which is difficult to meet the high-efficiency needs of modern production. Utility Model Content

[0012] The automatic replacement device for the grate bars of the sintering machine trolley according to this solution has at least the following technical effects:
[0013] The automatic grate bar replacement device for the sintering machine trolley drives the long-arm robot to the grate bar of the sintering machine trolley through a mobile vehicle, and can accurately pick up the grate bar through the movable arm and clamping assembly, and inspect the picked up grate bar. The visual recognition camera accurately identifies whether the grate bar needs to be replaced. The grate bar to be replaced is placed in the placement box through the movable arm and the clamping assembly, and then a new grate bar is picked up from the spare box for replacement, and the grate bar that does not need to be replaced is put back to its original place. The automatic grate bar replacement device for the sintering machine trolley realizes the automatic replacement of the grate bar, eliminating the manual replacement steps of the operator, and greatly shortens the downtime for maintenance, thereby improving work efficiency.
[0014] As a further solution of the utility model: telescopic adjustment mechanisms are respectively provided on both sides of the clamping jaws.
[0015] Since telescopic adjustment mechanisms are provided on both sides of the clamping jaws, the clamping jaws can be adjusted as needed to adapt to the sizes of different grate bars, thereby improving the adaptability of the device so that it can be applied to different types of sintering machine trolleys; and the clamping stability can be enhanced to ensure that the clamping jaws will not loosen or slide when clamping the grate bars.
[0016] As a further solution of the utility model: an angle fine-tuning mechanism is provided at the bottom of the clamping jaw.
[0017] Since an angle fine-tuning mechanism is provided at the bottom of the clamping jaw, the contact area between the clamping jaw and the grate bar is increased by fine-tuning the angle, ensuring uniform distribution of the clamping force and preventing the grate bar from sliding or falling during the clamping process, thereby improving the stability of the clamping.
[0018] As a further solution of the utility model: a connecting rod is arranged in the middle of the top of the mounting plate, and the clamping assembly is detachably connected to the movable arm via the connecting rod.
[0019] Since a connecting rod is provided in the middle of the top of the mounting plate, the clamping assembly is detachably connected to the movable arm through the connecting rod, so that the clamping assembly can be easily disassembled from the movable arm, the clamping assembly can be quickly repaired or replaced, and different types of clamping assemblies can be installed at the same time to suit different application scenarios.
