[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. The mine pressure acts on the hydraulic supports as an external load. Hydraulic supports mainly consist of hydraulic cylinders, load-bearing structural components, pushing devices, control systems, and other auxiliary devices. They are mainly developing towards greater strength, reliability, speed, and automatic control to meet the requirements of high-yield and high-efficiency coal mining. To this end, we are vigorously developing and promoting electro-hydraulic automatic control technology, improving the hydraulic supply system, enhancing the support capacity and reliability of the supports, and simplifying the structure and operation.
[0003] However, current mining hydraulic supports, once adjusted, are not easily fine-tuned according to the situation and require adjustment by moving the entire device, causing inconvenience in use. Therefore, there is a need to propose a mining hydraulic support that is easy to adjust. Utility Model Content
[0004] The technical problem to be solved by this application is that: the current mining hydraulic supports, after being adjusted, are inconvenient to make fine adjustments according to the situation, and adjustments still need to be made by moving the whole device, which makes them inconvenient to use.
[0005] To address the aforementioned technical problems, this application provides an easily adjustable mining hydraulic support, comprising a base plate, a motor mounted on the side of the base plate, a threaded rod mounted on the output end of the motor, a threaded cylinder threadedly connected to the surface of the threaded rod, a first slide rail mounted on the surface of the base plate, a first slider slidably connected to the surface of the first slide rail, a supporting base plate connected to one end of the first slider, a hydraulic cylinder mounted on the top of the supporting base plate, and a supporting top plate mounted to one end of the hydraulic cylinder.
[0006] Furthermore, there are two first slide rails, which are symmetrically installed on the top of the base plate, and one end of the first slider is connected to the threaded cylinder.
[0007] Furthermore, a second slide rail is installed on the top of the support base plate, and two second sliders are slidably connected to the surface of the second slide rail. A rotating shaft is installed at one end of each of the two second sliders, and an X-shaped support rod is rotatably installed on the surface of the rotating shaft. One end of each of the two second sliders is movably connected to the X-shaped support rod through the rotating shaft.
[0008] Furthermore, a third slide rail is provided at the bottom of the supporting top plate, and two third sliders are slidably connected to the surface of the third slide rail. The rotating shaft is installed on the surface of the third sliders, and one end of the two third sliders is movably connected to the X-shaped support movable rod through the rotating shaft.
[0009] Furthermore, the number of hydraulic cylinders is four, and the two ends of the four hydraulic cylinders are respectively connected to the support base plate and the support top plate.
[0010] Furthermore, omnidirectional wheels are installed at the four corners of the bottom of the base plate, and a connecting plate is provided on the surface of the omnidirectional wheels. An electric push rod is provided on the surface of the connecting plate, and one end of the electric push rod passes through the connecting plate and is connected to the insert rod.
[0011] This utility model has at least the following beneficial effects:
[0012] By setting up a motor, the motor can drive the threaded rod to rotate, causing the threaded cylinder to move. In conjunction with the first slide rail and the first slider, the support base plate moves, thereby causing the support top plate to move. This allows for easy adjustment of the position of the support top plate as needed, without having to move the overall position of the device. This improves the flexibility and practicality of the device. Attached Figure Description
