Description

Technical Field

[0001] The invention relates to the technical field of mine exploitation, and in particular to intelligent zoning support equipment for safe mine exploitation. Background Art

[0002] Mining refers to the extraction of naturally occurring minerals, whether solid (such as coal and minerals), liquid (such as crude oil) or gas (such as natural gas). This includes underground or above-ground mining, the operation of mines, and all auxiliary work generally carried out at or near the mine site to process raw materials, such as crushing, ore dressing and processing.

[0003] Safety is always a key issue in mining. Traditional mine support equipment usually relies on manual operation and static support structures, which has many shortcomings.

[0004] First, traditional support equipment usually requires a lot of manual intervention and operation, which not only increases the labor intensity of workers, but also may lead to operational errors due to human factors, increasing safety hazards. Manually operated support equipment is difficult to achieve accurate and rapid support adjustments, affecting mining efficiency. Secondly, existing support structures are mostly fixed designs, lack flexibility, and are difficult to adapt to complex and changeable geological conditions. The terrain inside the mine is often unpredictable, and the uneven surface increases the difficulty of support work. Traditional equipment is difficult to provide uniform and effective support, which may cause landslides or structural damage. Summary of the invention

[0010] Preferably, the auxiliary support mechanism includes an auxiliary support frame and a support rod fixedly connected to the side wall of the support frame. The auxiliary support frame is arranged in an L shape. The outer end of the support rod is fixedly connected to a rotating shaft. The auxiliary support frame is rotatably connected to the rotating shaft at the middle part, and a guide groove is opened on the inner wall of the auxiliary support frame.

[0011] Preferably, an electric slide rail is provided on the inner wall of the back side of the support frame, a guide block is fixedly connected to the movable end of the electric slide rail, and an outer wall of the guide block passes through and is slidably connected to the inner wall of the guide groove.

[0012] Preferably, the rotary connecting tube is communicated with the sealing sleeve, the inner end of the moving rod is fixedly connected with a piston ring, and the piston ring piston is connected to the inner wall of the sealing sleeve.

[0013] Preferably, the rotary connecting pipe is provided with a plurality of through grooves at the embedded position of the conveying ring, and the through grooves are arranged in a circular angle array at the center of the rotary connecting pipe, so that the hydraulic oil conveyed by the conveying pipeline can enter the rotary connecting pipe through the conveying ring.

[0015] Preferably, the conveying ring is hollow, the conveying ring is connected to the hydraulic oil tank through a conveying pipeline, and the conveying ring is rotatably connected to the outer wall of the rotating connecting pipe.

[0016] Working principle: When support is required, the coordinates of the support area are located and the information is transmitted to the mobile base. The entire device is moved to the corresponding location through the mobile base. After moving to the corresponding location, the drive motor is started according to the actual detected position that needs support. The drive motor drives the worm to rotate, and the worm drives the worm wheel to rotate, thereby controlling the rotation of the rotating connecting pipe. The rotating connecting pipe drives the sealing sleeve and the two sets of moving rods and the outer support mechanism to rotate. When it rotates to the designated support position, the hydraulic cylinder is controlled to start, and the hydraulic oil in the hydraulic oil tank enters the rotating connecting pipe through the delivery pipe and the through groove, and the moving rods on both sides are pushed outward by the hydraulic oil, so that the moving rods drive the support mechanism to move outward, and several groups of support arms will first contact the target area, and then the hydraulic oil in the connecting plate will produce a corresponding flow, so that the connecting rods in other areas are pushed outward, so that several groups of support arms can better contact and fit the target area, thereby achieving a better support effect. After supporting, the electric slide rail is started to drive the guide block to move upward, and the guide block moves along the inner wall of the guide groove, and drives the auxiliary support frame to rotate at a certain angle, so that the end of the auxiliary support frame contacts the ground and produces a supporting effect, thereby assisting the entire device in supporting.

[0017] The present invention provides an intelligent zoning support device for safe mining of mines. It has the following beneficial effects:

[0018] 1. The present invention adopts a structure composed of multiple independent connecting rods. These connecting rods can adjust their positions according to the changes in the surrounding terrain during the support process. When some connecting rods are unable to move forward due to greater resistance, other connecting rods can continue to move, ensuring that the support system can fit the irregular support surface. This feature enables the equipment to provide good support effects when facing the complex and changeable geological conditions inside the mine, prevent the occurrence of safety hazards such as collapse, and improve the safety and reliability of the overall operation. At the same time, the support angle can be automatically adjusted by the drive motor and the worm gear transmission system to ensure the rapid and accurate support action.

[0019] 2. The present invention greatly reduces the risk of safety accidents caused by human operational errors through intelligent control of the equipment and a stable support structure. At the same time, the auxiliary support mechanism can increase additional stability and ensure stable support of the equipment. The labor intensity of workers is significantly reduced, and only limited manpower is required for monitoring and maintenance, which greatly improves the convenience of construction.

[0020] 3. The intelligent support equipment of the present invention realizes automatic movement and precise positioning of the equipment through remote control of the central control system. The mobile base is equipped with independently driven crawlers, which can automatically navigate to the position requiring support according to preset coordinates. It not only greatly reduces the dependence on manual labor, but also avoids the positioning error caused by manual operation, thereby improving construction efficiency.
