Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a rapid adjustment and self-stabilizing device for a mining hydraulic support. Background Technology

[0002] As mining develops towards comprehensive mechanization and high efficiency, hydraulic supports, as the core equipment for fully mechanized coal mining, primarily function to support the roof strata in real time during the coal mining process, preventing roof collapse and rock leakage. At the same time, they provide a stable working space for the coal mining machine and scraper conveyor, directly determining the safety, efficiency, and recovery rate of mining operations.

[0003] Regarding the aforementioned problems with hydraulic supports for mine support, Chinese Patent Publication No. CN223152077U discloses a hydraulic support for mine operation, including support components. The support components consist of two sets: Support Component One and Support Component Two, symmetrically placed within the mine roadway. A fixing plate connects Support Component One and Support Component Two, which have identical structures. This utility model belongs to the field of mining equipment technology. A threaded rod sequentially penetrates the bottom wall of the support component, the pad, and the base plate before inserting into the ground, thus fixing the equipment. Nuts can be used to tighten the support component, pad, and base plate. An external air pump inflates the storage chamber through an air inlet. The gas in the storage chamber enters the slot through a vent. The elastic element in the slot bulges out, conforming to the uneven surfaces in the mine roadway. Simultaneously, the bulging elastic element also buffers the rigid impact forces encountered in the mine.

[0004] The above-mentioned solution proposes a method of fixing the equipment by having a threaded rod sequentially move through the bottom wall of the support, the pad, and the base plate before inserting it into the ground. However, in actual use, hydraulic supports need to be moved. The above-mentioned solution fixes the hydraulic supports in a designated position, which makes it inconvenient to adjust the position of the supports and cannot be adjusted according to the progress of coal mining. This results in the inability to cover the newly exposed roof after the coal mining machine cuts the coal, causing the roof to lose support and reducing the efficiency and safety of mining operations. Therefore, we provide a rapid relocation and self-stabilizing device for mine hydraulic supports. Utility Model Content

[0009] In some embodiments, both the electric adjusting push rod and the capacitive electronic level are electrically connected to the controller.

[0010] In some embodiments, the splicing slide rail mechanism includes a force-bearing plate located at the bottom of a U-shaped support frame. Connecting blocks are fixedly connected to both the front and rear sides of the left side of the force-bearing plate, and connecting grooves are fixedly opened on both the front and rear sides of the right side of the force-bearing plate. An I-shaped slide rail is fixedly connected to the top of the force-bearing plate, and limiting sliders are sleeved on both outer sides of the I-shaped slide rail.

[0012] In some embodiments, the I-shaped slide rail is slidably connected to the ceramic connecting block.

[0013] In some embodiments, the first support component and the second support component are fixedly connected by a fixing plate.

[0014] This utility model has at least the following beneficial effects: This invention utilizes a self-stabilizing adjustment mechanism. During adjustment, the pad is removed, and a capacitive electronic level detects the inclination of the base plate. A controller automatically adjusts the electric push rod to keep the support column perpendicular to the ground, ensuring that support components one and two remain perpendicular to the roof, thus guaranteeing continuous support. Simultaneously, multiple U-shaped support frames disperse downward pressure, further reducing vertical pressure and improving stability during adjustment. This allows for adjustments based on the coal mining progress, preventing newly exposed roof sections and ensuring continuous, stable support, thereby improving the efficiency and safety of mining operations.
