Description

A coal mill grinding bowl liner processing device Technical Field

[0001] This utility model relates to the field of coal mill technology, and in particular to a coal mill grinding bowl liner processing device. Background Technology

[0002] Coal mills are core equipment in industries such as thermal power generation and cement production. As wear-resistant components that come into direct contact with pulverized coal, the grinding bowl liners are subjected to high-intensity impacts and wear over a long period of time. Therefore, the processing quality of the grinding bowl liners is of great importance.

[0003] In the processing of grinding bowl liners, lathes, shapers, or manual milling machines are often used to grind the liners. However, if the liners are large and the processing equipment cannot grind them properly, or if some small and medium-sized enterprises lack processing equipment, the existing method is to make a liner mold, then overlap the mold with the liner, and then manually grind it with a hand-held grinding wheel. However, this grinding method still has the following shortcomings in actual operation:

[0004] 1. After the liner plate and the mold are stacked, in order to ensure its stability, the mold and the liner plate are often fixed by spot welding. This method is not only time-consuming and laborious to operate, but also very inconvenient to clean up afterwards.

[0005] 2. In order to ensure the stability of the liner and the mold, clamps or bolts are used to fix the liner and the mold. However, this method is prone to displacement due to uneven force, which affects the grinding accuracy.

[0006] 3. When fixing the mold and the liner plate with a C-type clamp, the clamp is very likely to block the grinding part of the liner plate, thus affecting the subsequent grinding operation.

[0007] Therefore, there is an urgent need for a coal mill grinding bowl liner processing device that can overcome the above-mentioned shortcomings. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, this utility model discloses a coal mill grinding bowl liner processing device. This utility model can not only stack and clamp the liner and mold in a convenient and efficient manner, but also avoids obstructing the grinding part of the liner.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A coal mill grinding bowl liner processing device includes a fixed frame, which has a rectangular frame structure;

[0011] The outriggers are located at the bottom of the fixed frame and are used to provide horizontal support for the fixed frame.

[0012] Several support members are located inside the fixed frame and are spaced apart along the length of the fixed frame. The support members are higher than the upper surface of the fixed frame and are used to provide horizontal support for the liner and the mold.

[0013] The movable frame has a rectangular frame structure and can be lifted and installed on the upper part of the fixed frame;

[0014] Several pressing components are located inside the movable frame and correspond one-to-one with several supporting components. The pressing components are lower than the lower surface of the movable frame and cooperate with the supporting components to clamp and limit the liner and mold.

[0015] Furthermore, the support components include:

[0016] The support rod is parallel to the fixed frame and higher than the upper surface of the fixed frame;

[0017] Two connecting rods are located at both ends of the support rod and are respectively connected to the two inner side walls of the fixing frame.

[0018] Furthermore, the pressing component and the support component have the same structure and are arranged in a mirror-symmetric manner.

[0019] Furthermore, the fixing frame is provided with a long rod that runs along the length of the fixing frame and is located at the lower part of the support. The upper part of the long rod is provided with a limiting rod for calibrating and overlapping the liner and the mold.

[0020] Furthermore, the fixing frame is provided with several long rods arranged in an orderly manner at intervals along the width direction of the fixing frame, and two limiting rods are provided on the upper part of the long rods.

[0021] Furthermore, the upper surface of the long rod is provided with a sliding groove along the length of the long rod, and the limiting rod can be detachably installed in the sliding groove and can be slidably adjusted along the sliding groove.

[0022] Furthermore, the slide groove is provided with a sliding block that can slide and adjust along the slide groove, and the limiting rod is inserted and connected to the upper part of the sliding block.

[0023] Furthermore, several lifting support rods are evenly distributed on the upper surface of the fixed frame, and the output end of the lifting support rods is fixedly connected to the movable frame.

[0024] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the support member and the pressing member, not only can the liner plate and the mold be firmly and stably clamped and fixed, but also the grinding part of the liner plate can be effectively exposed, providing strong support for the convenient and efficient grinding of the liner plate in the future.

[0025] By using spaced-out, rod-shaped support members and pressure members, the contact area with the liner can be effectively reduced, ensuring horizontal support for the liner. In addition, it greatly facilitates the forklift operation of the liner during subsequent loading and unloading.

[0026] By setting up fixed and movable frames with rectangular frame structures, it is not only easy for workers to pass through the contact positions of the support and clamping parts with the liner and mold during the loading process, ensuring the horizontal clamping and fixing of the liner and mold, but also facilitates the subsequent hoisting and unloading operations of the liner.

[0027] By setting a limiting rod, the limiting rod can be pressed against the end of the liner plate. When the mold and the liner plate are stacked, the mold is guided and placed, so that the mold and the liner plate can be accurately and efficiently overlapped and placed, which provides strong support for the subsequent high-quality grinding of the liner plate.

[0028] By setting up the slide groove and sliding block, it is not only convenient to slide and adjust the limit rod so that it can effectively abut against the end of the liner plate, but also the support component is prevented from affecting the sliding adjustment of the limit rod by inserting and pulling the limit rod.

[0029] This invention not only allows for convenient and efficient stacking and clamping of the liner and mold, but also avoids obstructing the grinding area of ​​the liner, greatly improving the grinding quality and efficiency of the liner and providing strong support for the production and processing of grinding bowl liners.

[0034] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0035] Please refer to Figures 1-3 in the specification. This utility model provides a technical solution:

[0036] Example 1: A coal mill grinding bowl liner processing device includes a fixed frame 4 with a rectangular frame structure. Several legs 6 are evenly distributed at the bottom of the fixed frame 4. Several support members 3 are arranged in an orderly manner along the length of the fixed frame 4 and are used to horizontally support the liner. Specifically, the support member 3 includes a support rod 7 that is parallel to the fixed frame 4 and located on the upper part of the fixed frame 4. Both ends of the support rod 7 are provided with connecting rods 8 that are respectively connected to the inner walls on both sides of the fixed frame 4. The upper part of the fixed frame 4 is provided with a movable frame 1 with a rectangular frame structure that is parallel to the fixed frame 4. Several lifting support rods 5 are evenly distributed on the upper surface of the fixed frame 4. The lifting support rods 5 are hydraulic telescopic rods or electric telescopic rods. The output end of the lifting support rods 5 is fixedly connected to the movable frame 1. Several pressing members 2 are provided in the movable frame 1 that cooperate with the support members 3 and are used to clamp and fix the liner and the mold. The pressing members 2 have the same structure as the support members 3 and are arranged in a mirror image symmetrical to the support members 3.

[0037] When grinding the liner, the worker can use a forklift to move the liner to the upper part of several support members 3 in the fixed frame 4. When supporting the liner, the support rod 7 in the support member 3 is used to support the liner, and the contact surface between the liner and the support rod 7 must be flat. After the liner is placed horizontally, the mold is placed on top of the liner. Then, the lifting support rod 5 drives the movable frame 1 to descend, and the pressing member 2 and the support member 3 cooperate to clamp and fix the liner and the mold. After the liner and the mold are fixed, the ends and outer edges of the liner and the mold are exposed. The worker can refer to the mold to efficiently complete the grinding process of the liner. The fixed frame 4, movable frame 1, support member 3 and pressing member 2 will not affect the worker's operation.

[0038] In Example 2, in order to ensure that the mold and the liner can be efficiently and accurately aligned during the stacking of the mold and the liner, the fixing frame 4 is provided with a long rod 12 that is set along the length of the fixing frame 4 and located at the lower part of the support 3. The upper part of the long rod 12 is provided with a limiting rod 9 for calibrating and overlapping the liner and the mold. Specifically, the upper surface of the long rod 12 is provided with a sliding groove 11 that is set along the length of the long rod 12. The sliding groove 11 is provided with a sliding block 10 that can slide and adjust along the sliding groove 11. The limiting rod 9 is inserted into the upper part of the sliding block 10.

[0039] Before placing the mold, the limiting rod 9 is slid to the end of the liner plate and then contacts it. The limiting rod 9 guides the mold to be placed in a high-efficiency and accurate manner with the liner plate. To improve the accuracy of mold placement, two sliding blocks 10 are provided in the groove 11 of the long rod 12. The limiting rod 9 on the two sliding blocks 10 can contact the two ends of the liner plate respectively. If the accurate placement of the mold cannot be guaranteed by only two-point positioning, multiple long rods 12 can be set and arranged in an orderly manner along the width direction of the fixing frame 4. The limiting rod 9 on each long rod 12 can position the end of the liner plate at multiple points. If the support member 3 interferes with the sliding adjustment of the limiting rod 9, the limiting rod 9 can be pulled out directly, the sliding block 10 can be slid past the support member 3 and then the limiting rod 9 can be inserted.
