Technical Field

[0001] The invention relates to the technical field of application of annular cooler equipment, and in particular to an annular track for emergency repair and replacement of wheels of annular cooler trolley and a use method thereof. Background Art

[0002] Annular coolers are widely used in the metallurgical industry, especially friction transmission type annular coolers. For this type of annular cooler, since the load-bearing and running movement of the trolley body are realized by the inner and outer ring wheels, when the trolley bodies of the annular cooler are filled with sintered ore during the production process, if the trolley wheel bearing is damaged, the trolley body will sink. After the trolley body sinks, the trolley can barely move forward a short distance, but it is not suitable for long-distance operation to unload materials at the curved track, which can easily cause a large number of damages to the lower trolley sealing device. The traditional annular cooler track does not take this abnormal situation into consideration, so that the production site often encounters the actual problem that the trolley wheel axle of the faulty trolley wheel cannot be lifted into place, which ultimately leads to the actual problem that the trolley wheel cannot be installed and replaced. Summary of the invention

[0003] The present invention provides a circular track for emergency repair and replacement of a ring cooler trolley wheel and a use method thereof, so as to solve the problem that during the repair and replacement of a faulty wheel of a ring cooler trolley, the trolley wheel axle cannot be lifted into place due to the sinking of the trolley body and the trolley wheel axle, and ultimately the trolley wheel cannot be effectively installed.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A circular track for rapid emergency repair and replacement of wheels of a circular cooling machine trolley comprises a track beam, a circular cooling machine track body is arranged on the top of the track beam, a circular emergency repair removable track and an emergency repair matching track are detachably connected between the circular cooling machine track bodies, a wedge surface is formed between the circular emergency repair removable track and the emergency repair matching track, the circular emergency repair removable track is a trapezoidal shape that is wide at the top and narrow at the bottom, and the emergency repair matching track is a trapezoidal shape that is narrow at the top and wide at the bottom.

[0005] Furthermore, the annular emergency repair detachable track and the annular cooler track body beside it are connected by a first fishtail clamp, and the annular emergency repair detachable track, the emergency repair matching track and the annular cooler track body beside the emergency repair matching track are connected by a second fishtail clamp.

[0006] Furthermore, the feet of the annular emergency repair detachable rail and the emergency repair matching rail are provided with rail pressing plates, and the rail pressing plates are fixed to the rail beam by second bolts.

[0007] The invention also includes a method for repairing and replacing the circular track of the ring cooling machine trolley wheel, which mainly comprises the following steps: Step 1: pre-assemble the removable emergency repair track, the emergency repair matching track and the ring cooler track body on the top of the track beam to make the wheels of the ring cooler trolley run normally.

[0008] Step 2: After the wheel of the ring cooler trolley is damaged and falls off the trolley body, the axle of the faulty trolley to be repaired and replaced is operated to the circular repair removable track of the circular track, the ring cooler switch is turned off, and after the ring cooler stops steadily, the center of the faulty trolley axle is adjusted to the top of the track beam to be an operable distance.

[0009] Step 3: first remove the first fishtail clamp, the annular emergency repair removable track and the track pressure plate located at the foot of the annular emergency repair removable track, replace the wheel bearing after removal, and assemble the wheel in place.

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] A circular track for emergency repair and replacement of wheels of a ring cooler trolley comprises a track beam 1, a ring cooler track body 2 is arranged on the top of the track beam 1, a ring cooler track body 2 is detachably connected with a ring repair removable track 3 and a repair matching track 4, and a wedge surface 7 is formed between the ring repair removable track 3 and the repair matching track 4.

[0018] A first fishtail clamp 5 is detachably connected between the annular emergency repair detachable track 3 and the annular cooler track body 2 next to it, and a second fishtail clamp 6 is connected between the annular emergency repair detachable track 3, the emergency repair matching track 4 and the annular cooler track body 2 next to it through a first bolt 8.

[0019] The annular emergency repair detachable track 3 is a trapezoid that is wide at the top and narrow at the bottom, and the emergency repair matching track 4 is a trapezoid that is narrow at the top and wide at the bottom.

[0020] A track pressing plate 9 is connected between the foot of the annular emergency repair detachable track 3 and the emergency repair matching track 4 and the track beam 1 via a second bolt 10 .

[0021] When the circular cooler trolley is fully loaded with materials during production, the wheel bearing of the trolley is damaged and the wheel falls off. At this time, the trolley body and trolley axle of the faulty wheel will inevitably sink by 50-80mm. If the trolley wheel is directly replaced and restored on the original traditional circular track, the trolley body and trolley axle of the faulty wheel will sink by 50-80mm. Even if a 50-100T jack is used to reset the lower part, the sunken trolley body cannot be completely reset because the sinking gap between the adjacent trolley bottom plates and the triangular beams is filled with sintered ore, resulting in insufficient space between the tread of the circular track and the center line of the trolley axle, and the trolley wheel cannot be installed. Therefore, the present invention pre-installs 3 emergency repair circular tracks on the inner and outer ring tracks of the circular cooler. When the trolley wheel of the circular cooler fails and needs to be repaired and replaced, the emergency repair first fishtail clamp 5, the first bolt 8 and the annular emergency repair removable track 3 of the annular track are disassembled. The increased clearance height of 120mm after disassembly is greater than the sinking amount of the car body of 50-80mm, ensuring that the height between the track seat and the trolley wheel axle fully meets the space size requirements for the replacement and reinstallation of the trolley wheel. Then the wheel bearing is replaced, and the wheel is directly powered on after it is assembled in place. At this time, the replaced "faulty trolley wheel" runs along the wedge surface 7 of the emergency repair matching track 4 to the head of the track section, and then the switch of the circular cooler is immediately stopped, and the first fishtail clamp 5, the annular emergency repair removable track 3, the first bolt 8 and the track pressure plate 9 are installed. After all are installed, the purpose of emergency repair and replacement of the trolley wheel of the circular cooler can be quickly achieved when the trolley body or the trolley wheel axle is not lifted into place.
