During the forward movement, there are risks such as the tail advance support frame falling over, the large chain breaking, and the cutting frame not being pulled straight. Therefore, it is necessary to design a cutting frame fixing device for the fully mechanized mining working face to solve this problem. Utility Model Content

[0003] The utility model aims to provide a fixing device for a top cutting frame of a fully mechanized mining working face, so as to solve the problems that the existing top cutting frame is inconvenient to move and cannot provide power for the top sliding of the machine tail.

[0004] To achieve the above-mentioned purpose, the utility model provides a fixing device for a top cutting frame of a fully mechanized mining working face, including a fixing plate. The fixing plate is in the shape of a right-angled triangle as a whole, including a vertical short side and a long side. The short side is away from the right-angle direction and is provided with a plurality of first pin holes parallel to the short side. The short side is placed under the side plate of the top cutting frame push block and is connected thereto by pins. The long side is away from the right-angle direction and is fixed with a connecting plate symmetrically up and down. The connecting plate extends to the outside of the long side, and the extended part is provided with a second pin hole. The connecting plate is clamped to the base of the tail worker slide frame and is connected thereto by pins.

[0005] Furthermore, the extended portion of the connecting plate is rectangular.

[0006] Furthermore, the short sides are arranged away from the right angle direction to form a rectangular shape.

[0007] Furthermore, two first pin holes are provided.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The device adopts a combination of fixed plate and connecting plate, with a simple and compact overall structure. The right-angled triangle design of the fixed plate effectively improves the stability of the structure, and the installation process is convenient and fast, greatly shortening the installation time and reducing the complexity of manual operation.

[0010] 2. By designing multiple pin holes and connecting plates, a tight connection can be achieved between the tail slide frame and the top frame push block, ensuring the stability of the top frame during the movement process. The device can effectively support the movement of the top frame, avoiding deflection and misalignment during the movement process, and ensuring the safety of the work surface.

[0011] 3. During the pushing process, the device can provide additional pushing assistance for the tail cutting top frame, effectively reducing the workload of pushing the thousand-pound machine and improving working efficiency.

[0012] 4. The fixing device of the utility model is not only applicable to the existing tail machine sliding frame and cutting frame, but can also be flexibly adapted to different types of fully mechanized mining working face equipment. It has strong adaptability and can operate stably under different working face conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to better understand the purpose, structure and function of the present invention, a fixing device for a fully mechanized mining working face cutting top frame of the present invention is further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a fixing device for a top cutting frame of a fully mechanized mining working face includes a fixing plate 1. The fixing plate 1 is in the shape of a right triangle as a whole, including a vertical short side 11 and a long side 12. The short side 11 is provided with a plurality of first pin holes 13 parallel to the short side 11 away from the right angle direction. The short side 11 is placed under the side plate of the top cutting frame push block 3 and is connected thereto by pins. The long side 12 is symmetrically fixed with a connecting plate 2 up and down away from the right angle direction. The connecting plate 2 extends to the outside of the long side 12, and the extended part is provided with a second pin hole 21. The connecting plate 2 is clamped to the base of the tail working slide frame 5 and is connected thereto by a pin.

[0020] The fixing plate 1 is triangular in shape, providing the most stable mechanical structure and meeting strength requirements. The short side 11, away from the right angle, is rectangular, and the extended portion of the connecting plate 2 is also rectangular, ensuring that the structure meets strength requirements. Two first pin holes 13 are provided.
