Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln wheel belts, in particular to an online grinding device for a rotary kiln wheel belt. Background Art

[0002] The existing rotary kiln equipment mainly includes a cylinder and a supporting device below, see attached Figure 3 The drum is equipped with two sets of belts and one set of gear rings. Generally, three sets of support devices are equipped to support the rotary kiln equipment, which correspond to the belts and gear rings respectively. The front and rear support devices have the same structure, each with two supporting wheels. The tug wheels are located on both sides of the bottom of the drum and dock with the belts to perform the main supporting function; the middle support device meshes with the gear ring to drive the drum to rotate.

[0003] Due to the large size of the cylinder (the normal load state of the rotary kiln of a 5000t / a production line is more than 1300 tons, and the first gear wheel diameter and wheel width are Ф5880*800mm), the surface of the large wheel will undergo slight deformation during long-term use, and the deformation will reduce the roundness of the wheel. If the deformation is too large, it will cause shaking when the cylinder rotates. The shaking of the large mass of the cylinder will impact the gear ring, causing equipment wear and posing a safety hazard. Therefore, it is necessary to grind the wheel surface to improve the roundness. However, the loss caused by the shutdown of a large production line is very large, so it is necessary to perform grinding operations without affecting the production of the rotary kiln. This plan is carried out in this context. Utility Model Content

[0004] Based on the above description, the utility model provides an online grinding device for a rotary kiln wheel belt to solve the problem that the rotary kiln wheel belt needs to be ground online in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A rotary kiln belt online grinding device, comprising:

[0007] Upper cover;

[0008] A lower cover, relatively arranged below the upper cover;

[0009] An elastic member connected between the upper cover and the lower cover;

[0010] The wear-resistant part is arranged on the upper surface of the upper cover.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the cross-sections of the upper cover and the lower cover are U-shaped, and the upper cover and the lower cover are sleeved.

[0013] Furthermore, a fixing plate is provided on the upper surface of the upper cover, and the wear-resistant part is embedded in the fixing plate.

[0014] Furthermore, the fixing plates are provided with two parallel groups, and the wear-resistant parts are embedded between the fixing plates.

[0015] Furthermore, a through hole is provided through the lower cover, and a guide rod connected to the upper cover is inserted into the through hole.

[0016] Furthermore, the guide rods are provided in a plurality of groups and are symmetrically arranged about the middle part of the lower cover.

[0017] Furthermore, the elastic member is a spring, and the spring is sleeved on the guide rod.

[0018] Furthermore, the guide rod is a screw rod, and a locking nut is sleeved on the bottom of the screw rod.

[0019] Furthermore, the screw is threadedly connected to the upper cover.

[0020] Furthermore, a connecting plate is connected to the bottom of the lower cover.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0022] The device is placed under the wheel belt. The upper cover is pressed to compress the elastic member so that the height of the upper cover is lowered, leaving a gap between the upper cover and the wheel belt to provide space for placing or replacing the wear-resistant parts. After the wear-resistant parts are placed, the wear-resistant parts maintain a force reaching a certain height under the action of the elastic member. By pre-adjusting the height of the grinding device, the wear-resistant parts will grind the protruding wheel belt. The entire device has a simple structure and is easy to manufacture, and can be ground when the rotary kiln is working online. BRIEF DESCRIPTION OF THE DRAWINGS

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0033] like Figure 3As shown, the rotary kiln column structure includes a cylinder 1, on which a belt 3 and a gear ring 2 are sleeved. The gear ring 2 is located in the middle of the cylinder 1. Two groups of belts 3 are provided and are respectively located on both sides of the gear ring 2. Two groups of supporting wheels are provided below each belt 3. The supporting wheels are symmetrically arranged on both sides of the bottom of the belt 3 for docking and supporting the belt 3. The bottom of the gear ring 2 is meshed with a driving device, which drives the gear ring 2 to drive the cylinder 1 to rotate, and the belt 3 is connected to the supporting wheels in a rolling manner.

[0034] like Figure 1 , Figure 2 The online grinding device for the wheel band 3 of a rotary kiln shown in the figure comprises an upper cover 4 and a lower cover 5, an elastic member 6 is arranged between the upper cover 4 and the lower cover 5, and a wear-resistant member 7 is placed on the upper surface of the upper cover 4. The grinding device is placed below the wheel band 3 and between the two supporting wheels, and the upper cover 4 is pressed to compress the elastic member 6 to approach the lower cover 5, thereby increasing the distance between the upper cover 4 and the upper wheel band 3, so as to leave a gap to place or replace the fixed wear-resistant member 7 above the upper cover 4, and then the pressure on the upper cover 4 is released, and the upper cover 4 rebounds to its original position under the action of the elastic member 6, driving the wear-resistant member 7 to contact with the wheel band 3, that is, under the action of the elastic member 6, the wear-resistant member 7 maintains a force reaching a certain height, and by pre-adjusting the height of the grinding device, the wear-resistant member 7 will grind the protruding wheel band 3, while the wheel band 3 whose size has not changed will not be polished, and under the continuous rotation of the wheel band 3, the wear-resistant member 7 is continuously polished so that the roundness of the wheel band 3 is continuously improved.

[0035] The upper cover 4 and the lower cover 5 can be plate-like structures, but in order to reduce the displacement of the upper cover 4 and the lower cover 5 during the pressing process, in one embodiment, the cross-section of the upper cover 4 and the lower cover 5 is U-shaped, the upper cover 4 with an inverted U-shaped configuration is sleeved with the lower cover 5 with a positive U-shaped configuration, and the side of the U-shaped structure forms a guide to avoid displacement. Preferably, a through hole is provided through the lower cover 5, and a guide rod 9 connected to the upper cover 4 is inserted into the through hole. The guide rod 9 is provided in several groups and is symmetrically arranged about the middle of the lower cover 5. The upper cover 4 and the lower cover 5 with a U-shaped structure solve the guidance in the X-axis direction, and the guide rod 9 strengthens the guidance on this basis, so that the upper cover 4 and the lower cover 5 have a guiding function in both the X-axis and Y-axis directions.

[0036] The elastic member 6 is preferably a spring, and the spring is sleeved on the guide rod 9. In order to improve the accuracy of the distance between the upper cover 4 and the lower cover 5 under the action of the spring, the guide rod 9 of the present solution is a screw, and a locking nut 10 is sleeved on the bottom of the screw. The distance between the upper cover 4 and the lower cover 5 is limited by the abutment between the locking nut 10 and the lower cover 5. The screw and the upper cover 4 can be welded or threaded. For easy disassembly, threaded connection is preferred. The lowest point of the wheel band 3 also has a certain height. In order to fix the present grinding device, a support column or other base with a certain height needs to be set. In order to dock the support column or base, a connecting plate 11 is fixedly set at the bottom of the lower cover 5, and the fixing method is welding or screw fixing.

[0037] Specifically, a fixing plate 8 is provided on the upper surface of the upper cover 4, and the wear-resistant part 7 is embedded in the fixing plate 8. In order to facilitate the insertion or removal of the wear-resistant part 7 from the side, the fixing plate 8 is provided with two parallel groups, and the wear-resistant part 7 is embedded between the fixing plates 8. The upper cover 4 is pressed to keep it away from the upper belt 3, and then the wear-resistant part 7 can be inserted or removed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
