Description

Technical Field

[0001] The utility model relates to the technical field of annular cooler equipment application, in particular to an annular track for rapid repair and replacement of wheels of annular cooler trolleys. 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 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 movement 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 practical problem that the trolley wheel cannot be installed and replaced. Utility Model Content

[0003] The utility model provides a circular track for the rapid repair and replacement of the wheels of a circular cooler trolley, so as to solve the problem that during the repair and replacement of the faulty wheels of the circular cooler trolley, the trolley axle cannot be lifted into place due to the sinking of the trolley body and the trolley axle, which ultimately makes it impossible to effectively install the trolley wheel.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A circular track for rapid emergency repair and replacement of wheels on a circular cooler trolley comprises a track beam, a circular cooler track body is provided 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 cooler 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 trapezoid with a wide top and a narrow bottom, and the emergency repair matching track is a trapezoid with a narrow top and a wide bottom.

[0006] Furthermore, the annular emergency repair detachable track and the annular cooler track body next to 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 next to the emergency repair matching track are connected by a second fishtail clamp.

[0007] Furthermore, the feet of the annular emergency repair detachable track and the emergency repair matching track are provided with track pressing plates, and the track pressing plates are fixed to the track beam by second bolts.

[0008] The utility model has the following beneficial effects:

[0009] The utility model provides a circular track for the rapid repair and replacement of the wheels of a ring cooler trolley. Multiple circular repair tracks are installed on the inner and outer ring tracks of the ring cooler. When the ring cooler trolley wheel fails and sinks under force, the repair fishtail splint, the circular repair detachable track and the track pressure plate of the track are disassembled. The increased clearance height after disassembly is higher than the sinking amount of the trolley body, thereby effectively ensuring that the height between the track seat and the trolley wheel axle fully meets the dimensional requirements of the trolley wheel replacement and reinstallation space, thereby realizing rapid replacement and installation in the emergency repair of the ring cooler trolley wheel.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] A circular track for rapid repair and replacement of wheels on a circular cooler trolley comprises a track beam 1, a circular cooler track body 2 is provided on the top of the track beam 1, a circular repair detachable track 3 and a repair matching track 4 are detachably connected between the circular cooler track body 2, and a wedge surface 7 is formed between the circular repair detachable track 3 and the repair matching track 4.

[0016] 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.

[0017] The annular emergency repair detachable track 3 is a trapezoid with a wide upper portion and a narrow lower portion, and the emergency repair matching track 4 is a trapezoid with a narrow upper portion and a wide lower portion.

[0018] The feet of the annular emergency repair detachable track 3 and the emergency repair matching track 4 are connected to the track beam 1 by a track pressing plate 9 through a second bolt 10.

[0019] When the circular cooler trolley is fully loaded with materials during the production process, the trolley wheel bearing is suddenly 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 circular track tread 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 rails on the inner and outer ring tracks of the ring cooler. When the ring cooler trolley wheel 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 rail 3 of the annular rail are removed. The increased clearance height of 120mm after removal is greater than the 50-80mm sinking amount of the vehicle body, ensuring that the height between the rail 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 assembled in place and the power is directly supplied and turned on. At this time, the replaced "faulty trolley wheel" runs along the wedge surface 7 of the emergency repair matching rail 4 to the rail head of this section of the track, and then the ring cooler switch is immediately stopped, and the first fishtail clamp 5, the annular emergency repair removable rail 3, the first bolt 8 and the rail pressure plate 9 are installed. After all are installed, the emergency repair and replacement purpose of the ring cooler trolley wheel can be quickly achieved when the trolley body or trolley wheel axle is not lifted into place. Therefore, the utility model has good practicality.
