Description

Technical Field

[0001] This utility model belongs to the field of elevator brakes, and in particular relates to an elevator brake fault monitoring device. Background Technology

[0002] The elevator brake is a crucial safety device in an elevator system. Its main function is to mechanically secure the elevator car to the guide rails when the elevator is stopped, preventing accidental movement. During normal elevator operation, the brake is released, allowing the traction machine to rotate freely and drive the car up and down. When the elevator needs to stop or in an emergency (such as a power outage or overspeed), the brake activates quickly, gripping the traction machine rotor tightly to stop the car and ensure passenger safety. The performance of the elevator brake directly affects the safety and reliability of the elevator; therefore, regular inspection and maintenance are necessary to ensure its reliable operation in critical situations.

[0003] Chinese patent CN217947273U discloses an elevator brake fault monitoring device. The device comprises a magnetic base, a sliding plate, a mounting plate, a detection rod, and a detection seat. A sliding plate is connected to one outer surface of the magnetic base. A mounting plate is fixedly mounted on the upper surface of one end of the sliding plate. The upper end of the mounting plate is penetrated by the detection rod. One end of the detection rod is fixedly connected to the detection seat, and the other end is fixedly connected to a rotating wheel. A sliding locking block is installed inside the inner cavity. This elevator brake fault monitoring device allows the detection seat to connect with brake pads of different thicknesses by engaging with the brake pads on an inclined surface. When the detection seat slides beyond its travel range, the locking block is pulled by a connecting chain, allowing it to slide downwards. This allows the detection seat to pass over the brake pads on the inclined surface, preventing the detection seat from being directly driven and colliding with the mounting plate.

[0004] However, in the above-mentioned solution, the elevator brake fault monitoring device is prone to displacement during sliding, and the internal spring is also prone to jamming. These structural problems may lead to inaccurate engagement between the detection seat and the brake pad, affecting the detection accuracy. Displacement and spring jamming may also affect the cooperation between the marker rod and the pressing block, thereby interfering with the normal triggering of the contact switch and preventing the indicator light from accurately reflecting the fault condition. Therefore, it is necessary to design an elevator brake fault monitoring device. Summary of the Invention

[0005] This utility model provides an elevator brake fault monitoring device, which aims to solve the problems of easy slippage and spring jamming in the currently used devices, which affect the detection accuracy and fault indication.

[0006] This utility model is implemented as follows: an elevator brake fault monitoring device includes: an elevator brake; a detection sliding assembly mounted on one side of the elevator brake, the detection sliding assembly being used to detect the strength of the elevator brake; a light-shielding moving assembly mounted on one side of the detection sliding assembly, the light-shielding moving assembly being used to synchronously detect the strength of the elevator brake; a brake strength display assembly mounted at the bottom of the light-shielding moving assembly, the brake strength display assembly being used to display the braking strength of the elevator brake; and a magnetic fixing assembly mounted on one side of the brake strength display assembly, the magnetic fixing assembly being used to fix the brake strength display assembly.

[0007] Preferably, the detection sliding assembly includes: a movable clamping plate detachably installed on one side of the elevator brake, with limiting mounting grooves movably installed on both sides of the movable clamping plate, a connecting rod fixedly installed on one side of the movable clamping plate, two sets of the connecting rods being provided, the two sets of the connecting rods being equidistantly arranged on the rear side of the movable clamping plate, and a push plate fixedly installed on the rear side of the two sets of the connecting rods, the push plate being movably sleeved inside the limiting mounting groove.

[0008] Preferably, the light-shielding moving component includes: a connecting plate one fixedly installed on one side of the push plate, a connecting plate two fixedly installed on one side of the connecting plate one, a light-shielding plate fixedly installed at the bottom of the connecting plate two, a ball groove opened at the top of the light-shielding plate, and a ball body movably installed inside the ball groove.

[0009] Preferably, multiple sets of ball grooves and ball bodies are provided, and the multiple sets of ball grooves and ball bodies are equidistantly arranged on the top of the smoothing plate.

[0010] Preferably, the braking intensity display component includes: a mounting detection frame fixedly installed at the bottom of the limiting mounting groove, a sensor fixedly installed inside the mounting detection frame, an indicator light fixedly installed on one side of the sensor, and a light sensor fixedly installed at the bottom of the sensor.

[0011] Preferably, the braking intensity display component further includes: a mounting frame fixedly installed inside the mounting detection frame, and a small spotlight is fixedly installed inside the mounting frame.

[0012] Preferably, the indicator lights are provided in multiple sets, and the multiple sets of indicator lights are equidistantly designed on one side of the sensor; the small spotlights are provided in multiple sets, and the multiple sets of small spotlights are equidistantly designed on the mounting frame.

[0013] Preferably, the magnetic fixing assembly includes: a battery fixedly installed on one side of the mounting and detection frame, a magnetic plate fixedly installed on one side of the battery, and the magnetic plate being detachably installed on one side of the elevator brake by magnetic attraction.

[0014] Compared with related technologies, the elevator brake fault monitoring device provided by this utility model has the following beneficial effects: The braking intensity causes the moving clamp of the sliding component to move along the limiting mounting groove. The connecting rod drives the push plate to move, which in turn moves the connecting plate one, connecting plate two, and the smooth plate of the light-shielding moving component. The multiple sets of ball grooves and ball bodies on the smooth plate reduce sliding resistance, prevent the device from sliding off-center, and improve detection accuracy. When the smooth plate moves, it blocks or exposes the photosensitive sensor in the braking intensity display component. The photosensitive sensor detects changes in light intensity and triggers multiple sets of indicator lights to illuminate, displaying the braking intensity. Meanwhile, multiple sets of small spotlights in the mounting frame provide a stable light source, ensuring accurate sensing by the photosensitive sensor and avoiding detection errors caused by unstable light sources. At the same time, the magnetic plate of the magnetic fixing component is powered by a battery and uses magnetic force to stably attach to one side of the elevator brake, preventing the device from loosening due to vibration and avoiding spring jamming. This ensures the accuracy of fault indication and effectively solves the problems of easy device sliding and easy spring jamming that affect detection accuracy and fault indication.
