Description

Technical Field

[0001] This invention belongs to the field of safety testing technology for mining equipment, specifically an intelligent anti-tipping hydraulic support system for steeply inclined working faces. Background Technology

[0002] In coal mining, especially in steeply inclined coal seams, mechanized longwall mining faces numerous challenges. One of the most prominent problems is the tendency for the working face supports to tilt, skew, or slide down along the dip angle. These issues not only affect production efficiency but also pose a serious threat to miners' lives. Traditionally, coal mining companies have adopted various mechanical and engineering measures to address these problems, such as installing adjustable support beams and movable side guards to enhance support stability. However, these methods often provide only limited support and prove inadequate when faced with complex and variable geological conditions.

[0003] With the development of technology, people have begun to explore more intelligent solutions. Some studies have proposed using sensor networks to monitor the posture of supports in real time and combining this with an automated control system to automatically adjust the support force. Nevertheless, existing intelligent systems still suffer from problems such as slow response speed, low accuracy, and poor adaptability. Due to the harsh and unpredictable underground environment, any new technological solution must take into account various limiting factors in practical applications to ensure its reliability and durability.

[0004] In view of the above situation, the present invention proposes an intelligent anti-tipping hydraulic support system specifically designed for steeply inclined coal seam fully mechanized mining faces. The system includes an anti-tipping control system for the working face support, which combines an inclination sensor, a traction hydraulic cylinder, a side support device, and anti-tipping V-shaped nail castings. It aims to provide faster and more precise attitude adjustment capabilities, thereby significantly improving the safety and reliability of the support. Summary of the Invention

When the angle approaches or exceeds the threshold, the system notifies on-site personnel through audible and visual alarms, screen prompts, etc., to intervene in advance to avoid tipping over.

[0018] 3. This invention provides an intelligent anti-tipping hydraulic support system for steeply inclined working faces. The traction hydraulic cylinder includes a support, a hinge fixing device, a hinge component, a cylinder body, and a piston rod. The traction hydraulic cylinder is the core actuator for actively adjusting the posture of the support.

The angle sensor 3 has a built-in microprocessor 303 that processes the data and sends the angle information to the control system through the data transmission interface 305. The control system presets a safety angle threshold. If the monitored angle approaches or exceeds the threshold, the system determines that there is a risk of tipping and triggers an audible and visual alarm to notify the operator. The active adjustment system automatically activates the following anti-tipping mechanisms: The pulling hydraulic cylinder 4 applies tension or thrust to the support through the extension and retraction of the hydraulic cylinder to correct the tilt posture. The hinged structure adapts to different terrains to ensure effective adjustment. The lateral support device 5 extends the outrigger cylinder 502, pushing the outrigger piston rod 503 to extend, so that the support foot contacts the ground to provide lateral support force. The anti-slip pad enhances stability and adapts to uneven ground. The anti-tipping V-shaped nail 601 extends and is embedded in the coal seam by the internal hydraulic jack to increase friction and prevent the base 106 from slipping. Attitude recovery and stabilization are achieved through the combined effect of the above-mentioned measures. The stent gradually restores a stable attitude, and the system continuously monitors to ensure that the stent operates within a safe range.

7. The intelligent anti-tipping hydraulic support system for a steeply inclined working face according to claim 6, characterized in that: The support (401) is welded to the upper surface of the base (106) to fix the traction hydraulic cylinder device (4). The hinge fixing device (402) is used to connect with and fix the hinge (403). One end of the hinge (403) is connected to the hinge fixing device (402) and the other end is connected to the cylinder body (404). The hinge fixing device (402) and the hinge (403) can rotate to adapt to different terrain conditions. The cylinder body (404) is used to store hydraulic oil and provide guidance for the piston rod (405). When the hydraulic system provides pressure, the oil enters the cylinder body (404) and pushes the piston to move. The piston rod (405) is used to connect the piston to the external load. Under the action of hydraulic pressure, it makes reciprocating linear motion along the axis, converting hydraulic energy into mechanical energy and driving the load connected to it to perform corresponding work.

The intelligent anti-tipping hydraulic support system for a steeply inclined working face according to claim 7, characterized in that: The lateral support device (5) is installed at the front and rear of the base (106) on one side of the working face support. The outrigger fixing device (501) is welded and fixed on the base (106). The outrigger cylinder (502) is hinged to the outrigger fixing device (501). One end of the outrigger piston rod (503) is connected to the outrigger cylinder (502) and the other end is hinged to the outrigger base (504). The outrigger base (504) is hinged to the outrigger fixing device (501) and located below the outrigger cylinder (502) and the outrigger piston rod (503). The support foot (505) is fixed at the end of the hydraulic outrigger and directly contacts the ground.

9. The intelligent anti-tipping hydraulic support system for a steeply inclined working face according to claim 8, characterized in that: The outrigger fixing device (501) is welded to one side of the base (106) of the working surface support, and is used to hinge the outrigger cylinder (502) and the outrigger base (504). One end of the outrigger cylinder (502) is hinged to the outrigger fixing device (501), and the other end is connected to the outrigger piston rod (503) to provide a sealed space to contain hydraulic oil and provide a sliding path for the piston. The outrigger piston rod (503) is an important component connecting the piston and the external actuator, responsible for transmitting the push and pull force generated by hydraulic drive. The outrigger base (504) is an important component of the lateral support device (5), responsible for transmitting the supporting force of the hydraulic outrigger to the ground. The support foot (505) increases the contact area between the lateral support device (5) and the ground, and is equipped with anti-slip pads to improve overall stability. It can be adjusted by adjusting the angle to adapt to uneven ground.

10. The intelligent anti-tipping hydraulic support system for a steeply inclined working face according to claim 9, characterized in that: The anti-tipping V-shaped nail casting (6) is installed in the middle right position of the top beam (102) of the working face support. The top anti-tipping V-shaped nail (601) is installed at the top position of the casting. The three top anti-tipping V-shaped nails (601) are arranged and installed in sequence. The anti-tipping V-shaped nail casting (6) is driven by an internal hydraulic jack. The top anti-tipping V-shaped nail (601) can be extended or retracted on the upper surface of the casting by the hydraulic jack.
