Problems solved by technology

However, there are defects in the principle of the traditional hydraulic support, which leads to the large internal force of the hydraulic support. The support stability of the hydraulic support is poor, and the coupling with the roof is poor, which cannot meet the needs of underground production safety and is not conducive to the smooth progress of comprehensive mining.

Embodiment 1

[0062] Such as Figure 1 to Figure 3 As shown, a new type of parallel hydraulic support includes a top plate 1, a bottom plate 3 and six hydraulic rods 5, the hydraulic rods 5 are arranged between the top plate 1 and the bottom plate 3, and the six hydraulic rods 5 are arranged in two rows and three One end of the hydraulic rods 5 is fixedly connected to the top plate 1 through the Hooke hinge 4, the other end of the hydraulic rods 5 is fixedly connected to the bottom plate 3 through the Hooke hinge 4, and the six hydraulic rods 5 are connected to the top plate 1 The connecting lines between the connecting points of the six hydraulic rods 5 and the connecting points of the base plate 3 form a rectangle.

[0063] Wherein, both the top plate and the bottom plate are arranged as rectangles, and the area of ​​the bottom plate is smaller than that of the top plate.

[0064] The working principle of the new parallel hydraulic support is: six hydraulic rods connect the top plate and...

Embodiment 2

[0066] Such as Figure 4 and Figure 5 As shown, a new type of parallel hydraulic support, the structure is as described in Embodiment 1, the difference is that the connecting line between the six hydraulic rods 5 and the connection points of the bottom plate 3 forms a hexagon.

Embodiment 3

[0068] Such as Figure 6 and Figure 7 As shown, a new type of parallel hydraulic support, the structure is as described in Embodiment 1, the difference is that the connecting line between the six hydraulic rods 5 and the connection points of the top plate 1 forms a hexagon.

Abstract

The invention relates to a new type of parallel hydraulic support and its application, comprising a top plate, a bottom plate and a plurality of drive rods, the drive rods are arranged between the top plate and the bottom plate, and the multiple drive rods are connected to Hooke hinges, spherical hinges or rotating The different combinations of pairs are fixedly connected to the top plate and the bottom plate, the connecting line between the driving rod and the connecting point of the top plate forms a quadrilateral or hexagonal shape, and the connecting line between the driving rod and the connecting point of the bottom plate forms a quadrilateral or hexagonal shape. The present invention enables the roof to have three to four degrees of freedom through different structural forms, and the roof can move in different positions to ensure that the roof can realize changes in different angles and positions, and can adapt to the complex movement of the roof stratum. The application is provided under the occasion, and its structural design is ingenious, easy to use and operate, the effect is remarkable, and it has good economic value and market benefit.

Description

technical field [0001] The invention relates to a novel parallel hydraulic support and its application, and belongs to the technical field of mining machinery equipment. Background technique [0002] With the continuous development of the energy industry, my country has become a big country in the utilization and mining of coal resources. Coal mining requires underground operations. In recent years, many mining accidents have occurred in the process of coal mining. Accidents caused by the collapse of the underground coal seam during the process, in order to solve the occurrence of mining accidents and ensure the safety of miners' underground operations, it is necessary to reinforce the underground coal seam to prevent casualties caused by the collapse of the coal seam. [0003] Hydraulic support is an important equipment to realize the integration, mechanization and automation of coal mining operations. The use of hydraulic supports can increase coal production, improve labo...
