Description

Technical Field

[0001] This utility model relates to the technical field of transportation equipment for underground fully mechanized mining faces in coal mines, and in particular to a tooling assembly for the middle trough of a scraper conveyor. Background Technology

[0002] In the field of coal mine transportation equipment manufacturing, scraper conveyors are key equipment for achieving efficient raw coal transfer. The central trough, as the core load-bearing component of the scraper conveyor, directly affects the operational stability and adaptability of the entire conveyor system through its production efficiency and dimensional accuracy. With the expansion of coal mining scale and the improvement of production efficiency, the demand for central troughs in scraper conveyors continues to grow, while the requirements for their dimensional accuracy (such as the dimensions of the connecting parts at both ends) are becoming increasingly stringent.

[0003] Traditional assembly methods require repeated measurements of the dimensions at both ends of the central tank (such as center height and width), which is cumbersome and time-consuming. Especially in the mass production of central tanks, the repetitive manual measurement and adjustment work significantly slows down the production progress and is difficult to adapt to the pace of large-scale production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the repetitive manual measurement and adjustment work in the middle trough during batch production of the middle trough significantly slows down the production progress and makes it difficult to adapt to the pace of large-scale production. Therefore, this invention proposes a combined tooling for the middle trough of a scraper transfer machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tooling assembly for the middle trough of a scraper conveyor, comprising two long plates, each with a vertical plate fixedly installed on its top, and a protrusion fixedly connected to the other end of each of the two long plates. A middle plate is fixedly connected between the two long plates, and the two ends of the middle plate are respectively provided with a convex end tooling and an L-shaped concave end tooling. Both ends of the convex end tooling are provided with convex holes, and the other ends of the two long plates are provided with convex grooves. A convex plate is embedded inside each of the convex grooves, and the convex plates are fixedly connected to the L-shaped concave end tooling.

[0006] Preferably, the bump is located inside and adapted to the convex hole.

[0007] Preferably, the center of the convex end tooling and the L-shaped concave end tooling are respectively provided with a first interface plate hole and a second interface plate hole.

[0008] Preferably, the surfaces of the convex end tooling and the L-shaped concave end tooling are respectively provided with a first circular hole and a second circular hole.

[0009] Preferably, the L-shaped concave end tooling is symmetrically fixedly connected with triangular plates inside.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the convex end tooling and L-shaped concave end tooling are used to accurately position the convex end tenon of the middle groove connecting ear, the interface plate and the concave end connecting ear and interface plate. Combined with the combination positioning structure of the middle plate and the bottom plate, one set of tooling covers the combination size positioning of the concave and convex end dumbbell mounting holes, the middle plate and the bottom plate, etc., avoiding manual measurement errors, ensuring the uniformity and accuracy of the middle groove size, ensuring smooth connection of the middle groove, and improving product quality and interchangeability.

[0011] 2. In this utility model, the tooling replaces the manual process of repeatedly measuring and adjusting. During assembly, the parts (such as the bottom plate of the middle groove, connecting ears, middle plate, etc.) only need to be placed according to the tooling positioning to quickly complete the leveling, alignment and assembly positioning. There is no need to measure the center height and width of both ends each time, which greatly shortens the assembly time, is suitable for mass production, and significantly improves production efficiency and assembly speed.

A middle plate 14 is fixedly connected between the two long plates 1. The two ends of the middle plate 14 are respectively provided with a protruding end tooling 4 and an L-shaped concave end tooling 8. Both ends of the protruding end tooling 4 are provided with protruding holes 5. The other ends of the two long plates 1 are provided with protruding grooves 12. A protruding plate 13 is embedded inside the protruding grooves 12. The protruding plates 13 are fixedly connected to the L-shaped concave end tooling 8.

[0017] The overall effect of embodiment 1 is as follows: vertical plates 2 are fixedly installed on the top of both long plates 1, and protrusions 3 are fixedly connected to the other ends of both long plates 1, which can make the convex holes 5 at both ends of the convex end tooling 4 fit on the protrusions 3. A middle plate 14 is fixedly connected between the two long plates 1, and the two ends of the middle plate 14 are respectively provided with convex end tooling 4 and L-shaped concave end tooling 8, which can make the middle plate 14 fix the long plates 1. Convex holes 5 are opened at both ends of the convex end tooling 4, and convex grooves 12 are opened at the other ends of both long plates 1. Convex plates 13 are embedded in the inside of the convex grooves 12, and the convex plates 13 are fixedly connected to the L-shaped concave end tooling 8, which can make the convex plates 13 on one side wall of the L-shaped concave end tooling 8 embedded in the convex grooves 12.

[0018] Example 2, as Figure 1-4 As shown, the protrusion 3 is located inside the convex hole 5 and is adapted to it; the center of the convex end fixture 4 and the L-shaped concave end fixture 8 are respectively provided with the first interface plate hole 6 and the second interface plate hole 9; the surfaces of the convex end fixture 4 and the L-shaped concave end fixture 8 are respectively provided with the first round hole 7 and the second round hole 10; the interior of the L-shaped concave end fixture 8 is symmetrically fixedly connected with the triangular plate 11.

[0019] The overall effect of embodiment 2 is as follows: by having the protrusion 3 located inside and adapted to the convex hole 5, the convex hole 5 can be fitted onto the protrusion 3; by having the first interface plate hole 6 and the second interface plate hole 9 respectively opened at the center of the convex end fixture 4 and the L-shaped concave end fixture 8, the middle plate 14 can be connected; by having the first round hole 7 and the second round hole 10 respectively opened on the surface of the convex end fixture 4 and the L-shaped concave end fixture 8, the middle groove can be adapted for installation; by having the triangular plate 11 symmetrically fixedly connected inside the L-shaped concave end fixture 8, the stability of the L-shaped concave end fixture 8 can be improved.

[0020] Working principle: On the production platform, according to the positions of the four connecting ears in the central slot, leveling blocks (used to support the bottom plate of the central slot) are welded. The convex end fixture 4 (which mates with the long plate 1 and the convex block 3 through the convex hole 5) is installed at the corresponding position of the convex end of the central slot, and the L-shaped concave end fixture 8 (which mates with the long plate 1 and the convex slot 12 through the convex plate 13) is installed at the corresponding position of the concave end of the central slot, completing the initial positioning of the fixtures. The bottom plate of the central slot is placed on the leveling blocks, and the connecting ears at both ends are placed on the bottom plate according to the design dimensions. The convex end fixture 4 is used to position the convex end tenon and interface plate of the connecting ears in the central slot, and the L-shaped concave end fixture 8 is used to position the concave end of the connecting ears in the central slot and the concave end interface plate, leveling and aligning the bottom plate and connecting ears. Subsequently, the middle plate 14 is assembled so that the lower plane of the concave and convex ends of the interface plate of the middle plate 14 is flush with the tooling. The tooling is used to determine the height dimension of the middle plate 14. At the same time, the tooling precisely constrains the dumbbell mounting holes of the concave and convex ends and the combined dimensions of the middle plate 14 and the base plate. Based on the positioning of the tooling, welding, fastening and other assembly operations are performed on the various components of the middle groove (base plate, connecting lugs, middle plate 14, etc.) to complete the overall assembly of the middle groove. Because the tooling has pre-ensured the dimensional accuracy and positional relationship of each component, the dimensions of the middle groove are uniform after assembly, and it can be smoothly connected. The tooling can be easily disassembled later to move on to the next middle groove assembly process.

[0021] The wiring diagram of the vertical plate 2 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the vertical plate 2 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
