[0001] This utility model relates to the field of mining hydraulic support technology, and in particular to a top beam for a mining hydraulic support. Background Technology

[0002] Mine hydraulic supports mainly come in three types: shield type, support type, and filling type. Shield type hydraulic supports are suitable for coal seam thicknesses, offering good support performance and height adjustment capabilities. Support type hydraulic supports are suitable for working faces with thinner coal seams, providing greater support force. Filling type hydraulic supports are suitable for working faces with significant variations in coal seam thickness, offering high adaptability.

[0003] A search of existing Chinese patent technology reveals a "detachable auxiliary device for the top beam of a hydraulic support in mining," with publication number "CN221879462U." This device is an auxiliary device for the top beam of a hydraulic support, which can be installed on the top beam of the hydraulic support to provide auxiliary support for the roof of the roadway on the upper support surface of the top beam. The angle can also be adjusted. However, since the top of the mine is not flat due to mining, the force on the top beam may be uneven during support, resulting in poor stability in supporting the top of the mine. Utility Model Content

[0004] Therefore, it is necessary to provide a mining hydraulic support beam to address the problem that the unevenness of the mine roof during mining can lead to uneven stress on the top beam, resulting in poor support stability for the mine roof.

[0005] A mining hydraulic support top beam is provided, comprising: two bottom seats, the upper ends of which are fixedly connected to two hydraulic push rods; a support mechanism, which is installed on the upper ends of adjacent hydraulic push rods; wherein the support mechanism includes a control component installed on the upper ends of adjacent hydraulic push rods, the upper end of the control component being disposed above the two bottom seats, and the upper end of the control component being connected to the support component.

[0006] In one embodiment, the control assembly includes a top plate fixedly connected to the telescopic end of the hydraulic push rod on one side, an upper rod fixedly connected to the upper end of the top plate, a side plate fixedly connected to the side of the top plate away from the support assembly, an anchor rod inserted into the inside of the side plate, one end of the anchor rod penetrating the side plate and extending to the side of the side plate away from the top plate.

[0007] In one embodiment, the support assembly includes a top beam fixedly connected to the upper end of the upper rod, and a plurality of support frames are fixedly connected to the inner bottom wall of the top beam, wherein two of the support frames and the inner wall of the top beam form an internal groove.

[0008] In one embodiment, a sliding sleeve is slidably connected to the surface of the upper rod, a connecting rod is fixedly connected between adjacent sliding sleeves, and a support top is provided between two connecting rods.

[0009] In one embodiment, support diagonal rods are fixedly connected to both sides of the support top, and the support diagonal rods are fixedly connected to the surface of the connecting rod.

[0010] In one embodiment, the surface of the upper rod is provided with a plurality of circular holes, which are evenly distributed in a straight line along the surface of the upper rod.

[0011] In one embodiment, a pin is inserted into the surface of the sliding sleeve, and one end of the pin is inserted into the interior of an adjacent circular hole.

[0012] In one embodiment, a hydraulic cylinder is fixedly connected to the inner wall of the internal groove, and the upper end of the hydraulic cylinder extends through to the upper end of the top beam.

[0013] Beneficial effects

[0014] 1. The above-mentioned mine hydraulic support top beam is positioned by anchoring rods that penetrate deep into the mine wall. The sliding sleeve slides on the surface of the upper rod, allowing the pin to be inserted into the round hole. This causes the sliding sleeve to move the connecting rod upward. Furthermore, the support diagonal rod drives the support top to provide auxiliary support to the lower end of the upper rod, making the top beam more evenly stressed and ensuring the stability of the support.

[0015] 2. Through the set support components, under the action of the support components, the upper ends of the set multiple hydraulic cylinders can assist in resisting the irregular protrusions on the top of the mine, so that the upper end of the top beam forms a uniform force effect on the top of the mine, maintaining the stability of the resisting support.
