[0002] In the process of coal mining, the jack is a very important tool, which can help miners perform various operations underground, such as equipment maintenance, replacement of parts, etc. The hydraulic jack, with its unique advantages, plays an irreplaceable role in ensuring the efficiency and safety of operations. Whether it is equipment maintenance in narrow spaces underground or maintenance of large machinery in open-pit mines, hydraulic jacks have demonstrated extremely high practicality and reliability.

[0003] The existing jacks used in coal mines are in the narrow space underground. When faced with the need to repair or replace parts of heavy machinery and equipment such as crushers, hydraulic jacks become one of the best choices for solving the problem with their compact design and powerful lifting capacity. It can be flexibly arranged in an extremely small space, and quickly provide the required power through a simple manual pump pressure method, easily achieving accurate positioning and stable support of the target object;

[0004] However, in a narrow coal mine, the ground of the coal mine may not be horizontal and there may be a slope. When the existing jack is placed on the slope, it may be tilted, which will make the top output end of the jack unable to stably lift the equipment. There are certain limitations during use, so it is necessary to set a corresponding adjustable structure for the jack. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable positioning device for a jack used in a coal mine to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is an adjustable positioning device for a jack used in a coal mine, comprising a bracket and a jack, wherein two arc frames are connected between two brackets, and the two arc frames are respectively at two ends of the bracket;

[0008] The upper surfaces of the two arc-shaped frames are respectively provided with arc-shaped grooves, the outer walls of the two arc-shaped frames are connected with arc-shaped racks, and the arc-shaped grooves and arc-shaped racks of the arc-shaped frames are provided with adjustment components for adjusting the angle of the jack, and the adjustment components move along the arc-shaped tracks of the arc-shaped frames and the arc-shaped racks;

[0009] A lifting component for lifting the jack is connected between the two adjustment components. A flat plate is installed on the top of the lifting component. A convex block is connected to the upper surface of the flat plate. The bottom of the jack is plugged into the convex block.

[0010] The purpose of the above arrangement is that the adjustment assembly moves along the arc groove and arc rack of the arc frame, thereby changing the angle of the jack. The adjustment assembly cooperates with the arc rack to provide precise angle adjustment, so that the jack can maintain the best working angle in different working scenarios;

[0011] The lifting component connects the two adjustment components, provides the lifting function of the jack, and adjusts the use height of the jack. The protrusions on the flat plate are plugged into the bottom of the jack to ensure the stability of the jack during the lifting process.

[0012] Furthermore, a connecting frame is connected to the outer walls of the two brackets, and a hole is arranged in the middle of the connecting frame.

[0013] The purpose of the above arrangement is that the connecting frame is connected to the outer walls of the two brackets, and the holes in the middle are used to pull and push the device through some rods, so as to adapt to the narrow space in the coal mine.

[0014] Furthermore, the adjustment assembly includes a motor and a roller, and the roller is slidably connected to the inner wall of the sliding groove of the arc frame;

[0016] The purpose of the above-mentioned setting is that the roller slides on the inner wall of the sliding groove of the arc frame to ensure that the adjustment component moves along the arc track. The output shaft of the motor passes through the roller and is connected to the gear. The gear and the arc rack are meshed with each other. When the motor is started, the gear rotates along the arc rack, driving the roller to move along the arc frame, thereby realizing the angle adjustment of the jack.

[0017] Furthermore, one end of the two fixed blocks is respectively rotatably connected to a first rotating rod, the top of the first rotating rod is rotatably connected to a connecting block, the top of the connecting block is rotatably connected to a second rotating rod, the flat plate is rotatably connected to the top of the two flat plates, and a bidirectional screw is threadedly connected between the two connecting blocks.

[0018] The purpose of the above arrangement is that the fixed block is installed on the outer wall of the roller as the supporting part of the lifting assembly, and the motor is installed on the lower surface of the fixed block to provide power for the rotation of the gear. The first rotating rod, the connecting block and the second rotating rod form a connecting rod structure, and the two-way screw connects the two connecting blocks through threads. When the two-way screw rotates, the distance between the two connecting blocks will change, and then the lifting and lowering of the plate will be realized through the rotation of the first rotating rod and the second rotating rod, thereby driving the lifting and lowering of the jack.

[0019] Furthermore, a slot is provided at one end of the bidirectional screw.

[0025] Furthermore, the block is located between two carrier blocks, and a spring is installed on the upper surface of the block.

[0026] The purpose of the above arrangement is that the wheel is rotatably connected to the bottom of the bracket, the wheel axle can slide on the movable groove of the bracket, the block is on the outer wall of the wheel axle, between the two carrier blocks, and a spring is installed on it. When the wheel is subjected to vibration or pressure, the block will squeeze the spring, and the spring will act as a buffer to reduce the impact of vibration on the entire device.

Pipes are connected between the four rubber cavities, and an oil inlet is connected on the outer wall of the rubber cavity, and a plug is threadedly connected to the port of the oil inlet.

[0030] The purpose of the above setting is that the rubber cavity is installed on the bracket and is located above the wheel. The four rubber cavities are connected by pipes. When a rubber cavity is under pressure, the oil inside will flow to other rubber cavities through the pipe, playing a role in buffering and balancing the pressure. The oil inlet can be used to replenish the oil or adjust the internal pressure, and the plug is used to seal the oil inlet.

[0031] The present invention has the following beneficial effects:

The output shaft of the motor passes through the roller and is connected to the gear. The gear and the arc rack are meshed with each other. When the motor is started, the gear rotates along the arc rack, driving the roller to move along the arc frame, thereby realizing the angle adjustment of the jack, thereby adapting to different angle requirements in the coal mine.

[0033] (2) The present invention sets a buffer component, wherein the rubber cavity is installed on a bracket and is located above the wheel. The four rubber cavities are connected by pipes. When a rubber cavity is subjected to pressure, the oil inside will flow to other rubber cavities through the pipe, thereby playing a role in buffering and balancing the pressure. The oil inlet can be used to replenish the oil or adjust the internal pressure, and the plug is used to seal the oil inlet.

[0034] (3) The present invention sets a buffer component, and the fixed block is installed on the outer wall of the roller as the supporting part of the lifting component. The motor is installed on the lower surface of the fixed block to provide power for the rotation of the gear. The first rotating rod, the connecting block and the second rotating rod form a connecting rod structure. The two-way screw connects the two connecting blocks through threads. When the two-way screw rotates, the distance between the two connecting blocks will change, and then the lifting and lowering of the flat plate will be realized through the rotation of the first rotating rod and the second rotating rod, thereby driving the lifting and lowering of the jack.
