Description

Technical Field

[0001] This utility model relates to the field of aerial passenger transport devices in mountainous areas, and in particular to a fault detection device for aerial passenger transport devices in mines. Background Technology

[0002] The aerial personnel carrier, also known as a "monkey car," is an important personnel transportation device in underground mines. Its working principle relies on a motor driving a drive wheel to rotate. The friction between the drive wheel and the steel wire rope drives the wire rope to circulate, and the passenger vehicle is suspended on the wire rope. As the wire rope moves, it facilitates the convenient transport of personnel. The aerial personnel carrier has many advantages: it can adapt to complex mine tunnel terrain, has strong climbing ability, effectively reduces the physical exertion of personnel walking, improves transportation efficiency, and operates relatively smoothly and reliably. It provides strong support for the daily commuting of underground mine personnel and plays an indispensable role in modern mining operations.

[0003] The continuous high-intensity operation of the aerial passenger transport system significantly increases the probability of equipment failure. During operation, the steel cable may slip or malfunction, causing the speed and rhythm of the passenger transport to become uncontrollable. Miners riding in the system may be thrown off due to sudden shaking and irregular acceleration, falling heavily in the limited space of the tunnel, resulting in serious injury and endangering their lives. However, the current maintenance equipment lacks an emergency braking mechanism, which cannot stop the movement of the steel cable in time when an accident occurs, leading to casualties. Furthermore, some braking mechanisms are not strong enough, allowing the steel cable to continue to slip. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fault detection device for aerial passenger transport in mines, aiming to improve the problem that the existing maintenance devices lack cable slippage monitoring devices and emergency braking mechanisms.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fault detection device for an aerial passenger transport device in a mine, comprising a frame beam, with a mounting base fixedly connected between two adjacent frames beams, a drive wheel rotatably connected to the top of the mounting base, a steel cable slidably connected to the outer wall of the drive wheel, a mounting platform fixedly connected to the upper end of the outer wall of the frame beam, a hydraulic rod fixedly connected to the middle of the mounting platform, one end of the hydraulic rod penetrating the outer wall of the mounting platform and fixedly connected to a connecting block, two secondary pressure rods rotatably connected to both ends of the connecting block, a primary pressure rod rotatably connected to the other end of the secondary pressure rod, the top of the primary pressure rod rotatably connected to the bottom of the mounting platform, a tertiary pressure rod rotatably connected to the lower end of the primary pressure rod, a clamping block rotatably connected to the lower end of the tertiary pressure rod, and a speed measuring mechanism provided on the outer wall of the mounting base for monitoring the sliding speed of the steel cable.

[0006] Through the above technical solution: a mounting base is fixed at the adjacent parts of the two beams. A set of rotating connecting devices is installed on the top of the mounting base, which allows the drive wheel to rotate flexibly. There is just the right amount of friction between the outer wall of the drive wheel and the steel cable. When the steel cable slides on the surface, it will not slip easily or wear excessively. Mounting platform one is fixed at the upper end of the outer wall of the beam. A hydraulic rod is fixed in the middle of mounting platform one. One end of the hydraulic rod passes through the outer wall of mounting platform one and is fixed to a connecting block. Secondary pressure rods are installed at both ends of the connecting block. The other end of the secondary pressure rod is rotatably connected to the primary pressure rod to ensure accurate force transmission. The top of the primary pressure rod is rotatably connected to the bottom of mounting platform one to form a stable triangular support structure. The lower end of the primary pressure rod is rotatably connected to the tertiary pressure rod. The lower end of the tertiary pressure rod is finally tightly connected to the clamping block. Through the multi-stage linkage structure, the pressure generated by the extension and contraction of the hydraulic rod is strengthened, which enables the steel cable to be firmly locked.

[0007] As a further description of the above technical solution:

[0008] The speed measuring mechanism includes a second mounting platform. One end of the second mounting platform is fixedly connected to the outer wall of the mounting base. A U-shaped block is fixedly connected to the top surface of the second mounting platform. A rotating rod is rotatably connected to the middle of the U-shaped block. A pulley is rotatably connected to the top of the rotating rod. A tension spring is fixedly connected to the upper end of the outer wall of the rotating rod. The other end of the tension spring is fixedly connected to the outer wall of the second mounting platform. A speed measuring device is provided on the outer wall of the second mounting platform.

[0009] Through the above technical solution: one end of the mounting platform is fixedly connected to the outer wall of the mounting base, providing a solid support foundation for subsequent components. A U-shaped block is fixed on the top surface of the mounting platform, and a rotating rod is rotatably connected to the middle of the U-shaped block. The rotating rod can rotate freely and flexibly within the range limited by the U-shaped block. A pulley is rotatably connected to the top of the rotating rod. A tension spring is fixedly connected to the upper end of the outer wall of the rotating rod, with one end fixed to the rotating rod and the other end fixedly connected to the outer wall of the mounting platform, providing stable tension assistance for the reset of the rotating rod. A speed sensor is installed on the outer wall of the mounting platform, which can capture the speed change information generated by the movement of the pulley, providing key data support for monitoring the operating status of the entire equipment.

[0010] As a further description of the above technical solution:

[0011] A fixed platform is fixedly connected to the outer wall of the mounting base, and the steel cable is arranged between the clamping block and the fixed platform.

[0012] The above technical solution involves a fixed platform fixedly connected to the outer wall of the mounting base, with steel cables positioned between the clamping block and the fixed platform to better lock the steel cables in place.

[0013] As a further description of the above technical solution:

[0014] The top surface of the fixed platform and the bottom surface of the clamping block are both provided with curved surfaces, and anti-slip blocks are fixedly connected to the outer wall of the curved surfaces.

[0015] The above technical solution involves designing curved surfaces on the top surface of the fixed platform and the bottom surface of the clamping block. These curved surfaces can better conform to the natural curvature of the steel cable. The outer wall of the curved surface is also fixedly connected with a layer of anti-slip block to prevent accidental sliding.

[0016] As a further description of the above technical solution:

[0017] A slide rail is fixedly connected between the adjacent mounting platform and the fixed platform. A limit block is fixedly connected to the outer wall of the clamping block, and the inner wall of the limit block is slidably connected to the outer wall of the slide rail.

[0018] Through the above technical solution: a set of high-precision slide rails are fixedly connected between the adjacent mounting platform and the fixed platform, and a limiting block is fixedly connected to the outer wall of the clamping block. Under the cooperative constraint of the limiting block and the slide rail, the clamping block can always move smoothly on the predetermined trajectory.

[0019] As a further description of the above technical solution:

[0020] A fixing plate is fixedly connected to the top surface of the beam, and a U-shaped rod is movably connected to the inner wall of the fixing plate.

[0021] Through the above technical solution, multiple fixing plates are fixed on the top surface of the beam, and the fixing plates have excellent compressive and deformation resistance.

[0022] As a further description of the above technical solution:

[0023] The lower end of the U-shaped rod is threaded with a nut, and a fixing beam is engaged with the inner wall of the U-shaped rod.

[0024] The above technical solution involves a U-shaped rod that is movably connected to the inner wall of the fixed plate. The lower end of the U-shaped rod is threaded, allowing it to be threadedly connected to the nut. The inner wall of the U-shaped rod engages with the outer contour of the fixed beam, effectively limiting the displacement of the fixed beam and buffering the impact of external forces to a certain extent.

[0025] As a further description of the above technical solution:

[0026] The outer wall of the pulley is in contact with the outer wall of the steel cable, and the outer wall of the pulley is provided with an anti-slip coating.

[0027] The above technical solution ensures that the outer wall of the pulley fits snugly against the outer wall of the steel cable, providing conditions for the smooth rotation of the pulley. The outer wall of the pulley is coated with an anti-slip coating, which ensures that the steel cable and the pulley maintain stable friction and prevents slippage, thereby guaranteeing the safe and stable operation of the entire system.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when it is necessary to stop the equipment urgently, the hydraulic rod presses down on the connecting block, the connecting block moves downward, the adjacent ends of the two secondary pressure rods press down, and the ends away from each other squeeze the connection between the primary pressure rod and the tertiary pressure rod, so that the tertiary pressure rod squeezes the clamping block downward. The steel cable is between the clamping block and the fixed platform. The clamping block and the fixed platform press the steel cable, so that the steel cable is fixed, that is, the equipment stops running. Through the multi-stage connecting rod pressurization, it is ensured that the compressive force is sufficient to stop the steel cable from sliding.

[0030] 2. In this utility model, when the equipment is running, the movement of the steel cable drives the pulley that is attached to the surface of the steel cable to rotate. The tension spring provides an elastic pressure to keep the pulley close to the surface of the steel cable. The speed measuring device monitors the linear velocity of the bottom edge of the pulley, that is, the speed of the steel cable. When the steel cable slips or a malfunction causes a change in the movement speed, it can be monitored in time and corresponding measures can be taken in time. Attached Figure Description
