Description

Technical Field

[0001] The utility model belongs to the field of sintering machine equipment, in particular to an anti-wear adjustable pressure rail used for arching of a trolley. Background Art

[0002] The impact of the sintering machine trolley arching on production and equipment cannot be ignored. At the least, the equipment will be damaged, and the resulting air leakage will affect the output and quality. At the worst, the sintering machine will be shut down. For sintering machines with a mobile swing frame structure at the tail, after a period of use, the exit track of the tail curved track return section will wear and the opening gap will increase, making it impossible for the exit track to effectively restrict the wheels of the trolley, resulting in the trolley arching phenomenon on the return track. The trolley arching phenomenon means that the rear wheels of the trolley are lifted up and do not contact the track, so that the trolley on the return section forms a zigzag shape. When the trolley runs to the head, due to the effect of its own weight or the effect of the head star wheel, the trolley gradually slides down or falls instantly to produce an impact, causing uneven wear on the anti-wear plate at the end of the trolley, and the wheels of the trolley are hit, affecting the use of the trolley and causing air leakage. Utility Model Content

[0003] The utility model aims to provide an anti-wear adjustable pressure rail for trolley arching, so as to solve the problems raised in the above-mentioned prior art.

[0004] Provided is a wear-resistant adjustable pressure rail for trolley arching, comprising:

[0005] The tail curved rail return section includes an exit upper rail and an exit lower rail;

[0006] The adjusting device is arranged at the junction of the arc segment and the straight segment in the outlet upper rail, and the adjusting device includes an adjustable pressure rail, a gasket and a support. The end face of the adjustable pressure rail and the end face of the outlet upper rail are located in the same horizontal plane, the gasket is clamped between the adjustable pressure rail and the support, and the adjustable pressure rail and the support are detachably connected.

[0007] Furthermore, the support and the adjustable pressure rail are connected via countersunk bolts.

[0008] Furthermore, the material used for the adjustable pressure rail is 50Mn2 alloy steel.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The adjustable rail pressure structure solves the arching problem of the trolley return track, improves the wear of the sintering machine trolley guardrail and anti-wear plate, and reduces the air leakage rate of the sintering machine trolley.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.

[0017] See also Figure 1-2 As shown, in an embodiment of the utility model, an anti-wear adjustable pressure rail for trolley arching includes a tail curved rail return section 1 and an adjustment device 2. The tail curved rail return section 1 includes an outlet upper rail 11 and an outlet lower rail 12. The adjustment device 2 is arranged at the junction of the arc segment and the straight segment in the outlet upper rail 11, and the adjustment device 2 includes an adjustable pressure rail 21, a gasket 22 and a support 23. The end face of the adjustable pressure rail 21 and the end face of the outlet upper rail 11 are located in the same horizontal plane, and the gasket 22 is clamped between the adjustable pressure rail 21 and the support 23. The adjustable pressure rail 21 and the support 23 are detachably connected.

[0018] The horizontal pressure rail on the tail curved rail outlet is extended by 300mm, and the extended section of 300mm is made into a movable pressure rail, namely the adjustment device 2. The installation dimensions of the outlet of the tail curved rail return section 1 are checked regularly. When the wear gap of the adjustment device 2 at the horizontal position of the outlet increases, the gasket 22 is added in time to adjust or replace the adjustable pressure rail 21, so that the gap of the outlet upper rail 11 of the tail curved rail return section 1 is always kept within the installation dimensions, and the tail curved rail inlet is always kept large and the outlet is small, and the height of the rear wheel of the trolley is pressed down. After the modification of the adjustable pressure rail device provided by the utility model, the arching phenomenon of the trolley is greatly improved, the wear degree caused by the continuous rubbing of different rails and anti-wear plates of the trolley can be effectively reduced, and the air leakage rate of the sintering machine is significantly reduced, thereby effectively ensuring the output of the sintering machine and the quality of the sintered ore.

[0019] The support 23 is connected to the adjustable pressure rail 21 by a countersunk bolt. When the adjustable pressure rail 21 changes in size due to wear, the countersunk bolt is removed, and the adjustable pressure rail 21 is disconnected from the support 23. At this time, the adjustable pressure rail 21 can be replaced or a gasket 22 can be added to adjust the adjustable pressure rail 21 back to the set position. The gasket 22 is clamped between the adjustable pressure rail 21 and the support 23, and the countersunk bolt avoids the clamping surface and enters from the side wall of the adjustable pressure rail 21 until it extends into the support 23. After the countersunk bolt is screwed into the bottom, the bolt is hidden inside the device as a whole, and there will be no protruding part that interferes with the wheels of the trolley, and the operation is stable and safe.

[0020] The material used for the adjustable rail 21 is 50Mn2 alloy steel. 50Mn2 alloy steel has high material strength and excellent wear resistance. Placing it at the place where the sintering machine track is most worn can significantly improve the operating stability of this place, so that the adjustable rail 21 can be used for a long time without being worn and replaced.

[0021] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
