Description

Technical Field

[0001] This utility model relates to the technical field of monorail crane equipment, specifically a monorail crane locomotive anti-derailment protection device. Background Technology

[0002] Mine roadways are narrow, undulating, and have many curves. Monorail locomotives, suspended from the roof rails, can transport personnel, various materials, equipment, and coal ore. However, after a train passes, the monorail switches may fail to accurately return to the "normally open" position due to mechanical wear, vibration, or malfunction, or the locking device may fail, causing misalignment of the rail gaps. If the locomotive driver or remote control system does not detect this, derailment is highly likely when the cab reaches this point. The sensors or visual signal systems used to detect the switch position may malfunction, providing the driver with an incorrect "switcheroo open" signal. The driver may then proceed based on this, leading to an accident. Existing protection devices only activate after the locomotive cab is lowered to the track, which can only prevent the drive unit, main engine, and other major components from falling off the track, but cannot prevent the entire locomotive from falling off the track, and cannot fully guarantee the safety of the driver and the locomotive. Utility Model Content

[0003] The purpose of this utility model is to provide a derailment prevention protection device for monorail locomotives. This device addresses the issue that if a monorail switch fails to accurately return to the "normally open" position due to mechanical wear, vibration, or malfunction, or if the locking device fails, resulting in misalignment of the rail gaps, the locomotive driver or remote control system may not detect this, and derailment can easily occur when the cab reaches this point. Furthermore, if the sensor or visual signal system used to detect the switch position malfunctions, providing the driver with an incorrect "switcheroo open" signal, the driver may proceed based on this, leading to an accident. Existing protection devices only function after the locomotive cab has fallen off the track, preventing only the drive unit and main engine from falling off, but not the entire locomotive, and thus failing to comprehensively guarantee the safety of both the driver and the locomotive.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a derailment prevention protection device for a monorail crane, installed on the monorail crane, including a mounting base, a guide base, a sliding plate, and a laser detector. Two mounting bases are provided, arranged in an L-shape, symmetrically positioned about the monorail track. Their vertical ends are bolted to the front crossbeam of the monorail crane's cab, while their horizontal ends rest on the crossbeam. Guide seats are symmetrically positioned on the front and rear sides of the top of each base. Sliding grooves are symmetrically formed on the corresponding end faces of the two guide seats, each containing a sliding plate that slides against the guide seat. A fixing frame is connected to the end of the sliding plate facing the monorail track, and the fixing frame has holes for mounting a laser detector. The detection end of the laser detector faces the monorail track. An internally threaded through-hole is formed in the middle of the sliding plate, containing a threaded rod. The bottom end of the threaded rod abuts against the top of the mounting base, which has an adjusting handwheel.

[0005] Preferably, a plurality of limiting grooves are evenly provided on the outer circumference of the adjusting handwheel, and limiting devices are respectively provided on the left and right sides of the adjusting handwheel.

[0006] Preferably, the limiting device includes a rectangular frame, a sliding rod, a retaining ring, a spring, and a limiting block. The rectangular frame is fixedly connected to the top of the guide seat. Through holes are symmetrically opened on the front and rear sides of the rectangular frame. The sliding rod passes through the through holes and slides in the rectangular frame. A limiting block that cooperates with the limiting groove is fixedly connected to the top of the sliding rod. A pull ring is connected to the other end of the sliding rod. A retaining ring is connected to the sliding rod located inside the rectangular frame. A spring is provided between the retaining ring and the inner wall of the rectangular frame and is sleeved on the sliding rod. One end of the spring abuts against the retaining ring, and the other end abuts against the rectangular frame.

[0007] Preferably, the contact end between the threaded rod and the mounting base is provided with a bearing seat, and the top of the transverse end of the mounting base is provided with a mounting groove for embedding the bearing seat.

[0008] Preferably, the laser detector is connected to the central processing unit (CPU) via signal connection, the CPU is connected to a relay, and the relay is connected to the monorail crane host.

[0009] Preferably, a limit baffle is connected to the end of the slide groove on the guide seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By installing two sets of laser detectors in front of the cab to detect the monorail track, if both sets of detectors fail to detect the track at the same time, the central processor directly acts on the relay, which transmits the signal to the host to cut off the power. This allows for early detection of track breakage and early braking of the locomotive, completely solving accidents such as the locomotive cab being suspended in the air or falling onto the track that occur when the monorail switch is constantly open.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-35. One embodiment of this utility model: A derailment protection device for a monorail crane, installed on a monorail crane 1, includes a mounting base 2, guide seats 3, a sliding plate 4, and a laser detector 7. Two mounting bases 2 are provided, arranged in an L-shape, symmetrically positioned about the monorail track. Their vertical ends are bolted to the front crossbeam of the monorail crane 1's cab, and their horizontal ends rest on the crossbeam. The entire device serves as a foundation support and mounting base. The vertical ends are fixed with bolts to ensure stability, while the horizontal ends resting on the crossbeam increase load-bearing capacity and anti-overturning ability. Guide seats 3 are symmetrically arranged on the front and rear sides of the top. Sliding grooves are symmetrically formed on the corresponding end faces of the two guide seats 3. Limit baffles are connected to the cut-off ends of the sliding grooves on the guide seats 3 to prevent the sliding plate 4 from exceeding the predetermined sliding range. Within the range, a sliding plate 4 is provided within the chute, offering a precise linear motion track. Two symmetrically arranged guide seats 3, through their internal chute, constrain the sliding plate 4 to only perform linear motion in the up-down direction, ensuring the stability and directional accuracy of the laser detector 7's movement. This allows it to align with the monorail for monitoring. The sliding plate 4 slides into the guide seats 3. A fixing frame 6 is connected to the end of the sliding plate 4 facing the monorail. The fixing frame 6 serves as a mobile platform for the laser detector 7, specifically designed to fix the laser detector 7. Mounting holes on the fixing frame ensure the laser detector 7 is securely installed and maintains the correct orientation. The sliding movement of the sliding plate 4 directly moves the laser detector 7 closer to or away from the monorail. The fixing frame 6 has holes for mounting the laser detector 7. The detection end of the detector 7 faces the monorail track. A threaded through-hole is provided in the middle of the slide plate 4, and a threaded rod 5 is installed inside the threaded through-hole. The bottom end of the threaded rod 5 abuts against the top end of the mounting base 2, and an adjusting handwheel 8 is provided at the top end. A bearing seat is provided at the contact end between the threaded rod 5 and the mounting base 2. A mounting groove for embedding the bearing seat is provided at the top of the transverse end of the mounting base 2. The design of the bearing seat and mounting groove transforms the rotational friction of the threaded rod 5 into rolling friction, making adjustment easier and smoother, and avoiding wear on the mounting base 2. Rotating the adjusting handwheel 8 can drive the threaded rod 5 to screw in or out of the threaded through-hole of the guide seat 3. Since the bottom end of the threaded rod 5 is connected to the mounting base 2 through the bearing seat, according to the principle of threaded transmission, the threaded rod 5 itself will not move up or down, pushing the slide plate 4 relative to it. Vertical fine-tuning is performed on mounting base 2. Laser detector 7 is connected to the central processing unit (CPU), which in turn connects to a relay. The relay is connected to the monorail crane's main unit. Mounting base 2 is bolted onto the front crossbeam of the monorail crane's cab 1. Rotating the adjusting handwheel 8 drives the threaded rod 5, simultaneously raising or lowering the sliding plate 4. Fine-tuning of laser detector 7 ensures its detection end aligns with the monorail crane's track. While the monorail crane 1 is moving, laser detector 7 continuously operates, transmitting real-time distance signals to the CPU. Two sets of laser detectors 7 detect the monorail crane's track. If both sets fail to detect the track simultaneously, the CPU directly activates the relay, which then transmits a signal to the main unit.This cuts off the power supply, effectively preventing injuries to personnel and damage to the locomotive caused by the cab falling onto the track.

[0022] Example 2: Please refer to Figure 4 Based on Example 1, it also has the following structure: Several limiting grooves are evenly provided on the outer circumference of the adjusting handwheel 8, and limiting devices 9 are respectively provided on the left and right sides of the adjusting handwheel 8.

[0023] The limiting device 9 includes a rectangular frame 901, a slide bar 902, a retaining ring 903, a spring 904, and a limiting block 905. The rectangular frame 901 is fixedly connected to the top of the guide seat 3, which is the base and outer shell of the entire limiting device 9. The rectangular frame 901 provides a precise sliding track and support for the slide rod 902 and encapsulates all internal parts together. Symmetrical through holes are provided on the front and rear sides of the rectangular frame 901. The slide rod 902 passes through these through holes and slides within the rectangular frame 901. Pushing and pulling the slide rod 902 within the through holes of the rectangular frame 901 ensures the linearity and precision of the movement. This drives the limiting block 905 to disengage from or engage with the limiting groove. A limiting block 905, which engages directly with the limiting groove, is fixedly connected to the top. Its shape matches the limiting groove, and it slides into the groove under spring force, achieving positive locking. A pull ring is connected to the other end. A retaining ring 903 is connected to the slide rod 902 located within the rectangular frame 901, transmitting the thrust of the spring 904 to the slide rod 902, thereby driving the limiting block 905 to embed into the limiting groove. A retaining ring 903 is provided between the retaining ring 903 and the inner wall of the rectangular frame 901. Spring 904, sleeved on slide bar 902, abuts against retaining ring 903 at one end and against rectangular frame 901 at the other end, providing power for automatic reset and preload for locking. Spring 904 is compressed between retaining ring 903 and inner wall of rectangular frame 901. Its elasticity continuously pushes retaining ring 903, thereby driving slide bar 902 and limit block 905 to move towards adjusting handwheel 8. When unlocking, pull ring of slide bar 902 moves slide bar 902, moving retaining ring 903 and engaging with rectangular frame 901, compressing spring 904, and simultaneously moving limit block 905 away from limit groove, unlocking adjusting handwheel 8. At this time, operate adjusting handwheel 8. After adjustment, release pull ring. The compressed spring 904 drives pull ring to move, simultaneously moving slide bar 902, resetting limit block 905, and locking adjusting handwheel 8.
