Description

Technical Field

[0001] This utility model belongs to the technical field of coal mining machine components, and in particular relates to a sealing structure for the traveling box of a coal mining machine. Background Technology

[0002] In coal mining operations, the coal mining machine is one of the key pieces of equipment. Its traveling box, as a crucial component for the movement and load-bearing of the coal mining machine, directly affects the normal operation and service life of the machine. During operation, the coal mining machine's traveling box faces complex and harsh working conditions, such as contact with large amounts of coal dust, water, and various impurities.

[0003] Existing sealing structures for coal mining machine travel boxes mostly employ a simple combination of a cover and a sealing ring. However, this conventional structure has significant shortcomings in practical use. Due to vibrations during coal mining machine operation and the influence of external forces, the cover and sealing ring are prone to loosening, preventing the cover from tightly pressing against the sealing ring. Once a gap appears between the cover and the sealing ring, impurities such as coal dust and water can easily enter the travel box. To solve these problems, we propose a new sealing structure for coal mining machine travel boxes. Utility Model Content

[0004] This utility model provides a sealing structure for the traveling box of a coal mining machine to solve the problems of easy loosening of the cover and sealing ring and poor sealing performance of the traveling box of a coal mining machine in the prior art.

[0005] This utility model is implemented as follows: a sealing structure for a coal mining machine traveling box includes a box body, a groove is provided on the top of the box body, a sealing ring is placed in the groove, the upper end face of the sealing ring is higher than the upper end face of the box body, a cover is provided at the upper port of the box body, the cover is placed on the sealing ring, and two spaced limiting mechanisms are provided on both sides of the box body, the limiting mechanisms are used to fix the cover and press the cover down on the sealing ring.

[0006] The limiting mechanism includes a support fixedly installed on the outside of the box, two spaced slide rails fixedly installed on the support, a movable plate above the support, two spaced sliders fixedly installed at the bottom of the movable plate, the sliders being slidably installed in the slide rails, a first inclined surface on the lower side of one end of the movable plate, when the movable plate slides to the cover, the first inclined surface contacts the cover and presses down on the cover.

[0007] Preferably, the bottom surface of the movable plate is provided with anti-slip texture.

[0008] Preferably, the movable plate has a slot at the top, a bracket is fixedly installed on the support, and a limiting component is installed on the bracket. The limiting component is inserted into the slot and limits the movable plate.

[0009] Preferably, the limiting component includes a limiting block located inside the bracket. Guide rods are fixedly installed at both ends of the top of the limiting block. The upper ends of the guide rods pass through the bracket and slide up and down on the bracket. Two symmetrically distributed elastic plates are fixedly connected to the limiting block. The upper ends of the elastic plates are fixedly connected to the bracket. A second inclined surface is provided on the upper side of one end of the movable plate. During the sliding of the movable plate, the limiting block contacts the second inclined surface.

[0010] Preferably, a circular plate is fixedly installed on the upper end of each guide rod.

[0011] Preferably, the corners of the movable plate are rounded.

[0012] Preferably, a handle is fixedly installed on the top of the cover.

[0013] Compared with related technologies, the sealing structure of the coal mining machine traveling box provided by this utility model has the following beneficial effects: By pushing the movable plate, the first inclined surface of the plate applies downward pressure to the cover, causing the cover to press tightly against the sealing ring, effectively enhancing the sealing effect, ensuring that the inside of the box is isolated from the external environment, and preventing leakage and other situations from occurring.

[0014] After the movable plate is moved into place, its horizontal surface contacts the top of the cover, and the anti-slip texture increases the friction between it and the cover, effectively preventing the cover from slipping off the sealing ring and further ensuring the stability of the seal.

[0015] During the sliding process of the movable plate, the cooperation between the second inclined surface and the limiting block, as well as the elastic force of the elastic sheet, allows the limiting block to automatically insert into the slot when the movable plate slides to the required position, precisely limiting the movable plate, preventing it from sliding, and ensuring that the cover can continuously and stably press on the sealing ring to maintain a good sealing state.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] A preferred embodiment of the sealing structure for the coal mining machine travel box provided by this utility model is, for example... Figures 1 to 5 As shown: A sealing structure for a coal mining machine traveling box includes a box body 1. A groove 2 is provided on the top of the box body 1, and a sealing ring 3 is placed in the groove 2. The upper end face of the sealing ring 3 is higher than the upper end face of the box body 1. A cover 4 is provided at the upper port of the box body 1, and the cover 4 is placed on the sealing ring 3. Two spaced limiting mechanisms 5 are provided on both sides of the box body 1. The limiting mechanisms 5 are used to fix the cover 4 and press the cover 4 down on the sealing ring 3.

[0021] The limiting mechanism 5 includes a support 6 fixedly installed on the outside of the housing 1. Two spaced slide rails 7 are fixedly installed on the support 6. A movable plate 8 is provided above the support 6. Two spaced sliders 9 are fixedly installed at the bottom of the movable plate 8. The sliders 9 are slidably installed in the slide rails 7. A first inclined surface 10 is provided on the lower side of one end of the movable plate 8. When the movable plate 8 slides to the cover 4, the first inclined surface 10 contacts the cover 4 and presses down on the cover 4.

[0022] The bottom surface of the movable board 8 is provided with anti-slip texture.

[0023] The top of the movable plate 8 has a slot 15, and a bracket 11 is fixedly installed on the support 6. A limiting component is installed on the bracket 11. The limiting component is inserted into the slot 15 and limits the movable plate 8.

[0024] The limiting component includes a limiting block 12 located inside the bracket 11. Guide rods 13 are fixedly installed at both ends of the top of the limiting block 12. The upper ends of the guide rods 13 pass through the bracket 11 and slide up and down on the bracket 11. Two symmetrically distributed elastic plates 14 are fixedly connected to the limiting block 12. The upper ends of the elastic plates 14 are fixedly connected to the bracket 11. A second inclined surface 16 is provided on the upper side of one end of the movable plate 8. During the sliding process of the movable plate 8, the limiting block 12 contacts the second inclined surface 16.

[0025] Place the sealing ring 3 in the groove 2 at the top of the box 1, and make the upper surface of the sealing ring 3 higher than the upper surface of the box 1. Then place the cover 4 on the sealing ring 3. At this time, the cover 4 and the sealing ring 3 are initially in contact, but a good sealing state has not yet been achieved.

[0026] Push the movable plate 8, and the slider 9 at the bottom of the movable plate 8 slides within the slide rail 7 fixedly installed on the support 6, causing the movable plate 8 to move towards the cover 4.

[0027] When the movable plate 8 slides to the cover 4, the first inclined surface 10 on the lower side of one end of the movable plate 8 contacts the cover 4. As the movable plate 8 continues to slide, the first inclined surface 10 exerts downward pressure on the cover 4, causing the cover 4 to press down on the sealing ring 3, thereby enhancing the sealing effect. After the movable plate 8 has moved completely, the horizontal surface on the movable plate 8 contacts the top of the cover 4. The anti-slip texture on the movable plate 8 increases the friction between it and the cover 4, making it less likely for the cover 4 to slip off the sealing ring 3.

[0028] On the other hand, during the sliding of the movable plate 8, the second inclined surface 16 on the upper side of one end of the movable plate 8 contacts the limiting block 12 located in the bracket 11. As the movable plate 8 continues to slide, the second inclined surface 16 applies upward pressure to the bottom end of the limiting block 12, and the limiting block 12 moves upward against the elastic force of the elastic sheet 14. At the same time, the guide rod 13 slides on the bracket 11, playing a guiding role.

[0029] When the movable plate 8 slides to the desired position, the slot 15 at the top of the movable plate 8 moves to the limiting block 12. Under the elastic force of the elastic piece 14, the limiting block 12 moves downward and inserts into the slot 15, thereby limiting the movable plate 8, preventing the movable plate 8 from sliding, and ensuring that the cover 4 is continuously and stably pressed on the sealing ring 3 to maintain a good sealing state.

[0030] In a further preferred embodiment of this utility model: A circular piece 17 is fixedly installed on the upper end of each guide rod 13. The circular piece 17 prevents the limiting block 12 and guide rod 13 from detaching from the bracket 11. The corners of the movable plate 8 are rounded. Rounding the corners of the movable plate 8 prevents potential scratches or bumps to personnel from sharp edges. A handle is fixedly installed on the top of the cover 4. When placing the cover 4 onto or removing it from the box 1, the operator can directly hold the handle, making the installation and removal of the cover 4 easier and more convenient. The handle's function is particularly important for heavier or larger covers 4.
