Description

Technical Field

[0001] This utility model relates to the field of ventilation duct support technology, and in particular to a ventilation duct support for a dust removal equipment in a mine. Background Technology

[0002] In the mining environment, dust control is crucial for ensuring the health and safety of miners. Large amounts of dust generated in the mine, if not dealt with promptly, can severely impact miners' respiratory systems and potentially lead to dust explosions and other safety accidents. As a key component of mine dust control, the stability and reliability of the ventilation system directly affect the effectiveness of dust suppression.

[0003] Currently, the ventilation duct supports used in mine tunnels have many problems. On the one hand, the geological conditions in mine tunnels are complex and variable, often accompanied by vibrations. Existing ordinary supports are unable to effectively cope with these vibrations, causing ventilation ducts to easily shift, loosen, or even be damaged, affecting the normal operation of the ventilation system. On the other hand, the spatial layout of different mine tunnels varies greatly, and the design of some supports lacks flexibility, making it impossible to easily adjust them according to the actual space, which poses significant difficulties for installation and maintenance.

[0004] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0013] Furthermore, the shock-absorbing ring plate includes a limiting plate, and the limiting plate is provided with a connecting sleeve connected to the shock-absorbing connecting cylinder. The limiting plate is provided with a limiting circular groove for penetrating the shock-absorbing connecting rod and having a longitudinal cross-sectional area larger than that of the shock-absorbing connecting rod.

A plurality of circumferential springs are provided between the circumferential outer cylinder and the circumferential inner cylinder.

[0015] Furthermore, both ends of the horizontal spring are in contact with the limiting plate and the shock-absorbing ring seat, respectively.

[0023] The shock-absorbing slider in the shock-absorbing connecting assembly of this utility model works in conjunction with the shock-absorbing spring on the vertical guide rod to effectively buffer the displacement of the ventilation duct caused by vibration in the vertical direction, greatly reducing the impact of vibration on the duct. At the same time, the horizontal spring in the shock-absorbing cylinder and the circumferential spring in the circumferential shock absorber absorb and disperse vibration from the horizontal and circumferential directions respectively, ensuring that the vibration of the ventilation duct in all directions can be effectively suppressed.

[0024] The connecting bracket and supporting bracket of this invention have an overall inverted T-shaped structure. This classic and stable design effectively distributes the weight of the ventilation duct and the external forces it bears. The parallel connecting plates and connecting bolts on the connecting bracket further enhance the overall rigidity and stability of the bracket. When facing complex geological stresses within the mine, the inverted T-shaped structure can better resist forces from different directions, ensuring the bracket remains stable in various harsh environments, providing reliable support for the ventilation duct, and reducing the risk of ventilation system failure due to bracket instability.

[0025] This invention allows for flexible adjustment of the position of the swing arm sliding frame on the swing arm connecting frame via swing arm screws, enabling precise adjustment of the relative position of the shock-absorbing frame and ventilation duct according to the actual space conditions within the mine tunnel. Furthermore, the fastening screws on the circumferential inner cylinder can adjust the tightness of the connection between the circumferential inner cylinder and the shock-absorbing ring seat to adapt to the shock absorption performance requirements under different working conditions. This height adjustability allows the support to be widely used in mine tunnels of various shapes and sizes, greatly improving the versatility and adaptability of the support, and reducing installation difficulties and cost increases caused by space limitations.
