Description

Technical Field

[0001] The invention relates to the technical field of mine transportation, in particular to a high-safety personnel transportation auxiliary device for preventing falling in underground mines. Background Art

[0002] As an important personnel transportation equipment in underground mines, the mine overhead passenger device (commonly known as "monkey car" in the industry) is mainly composed of a drive device, a detour device, a passenger chair, a wire rope and an electric control system. It adopts a continuous cycle operation mode, and realizes the long-distance and efficient transportation of workers in inclined tunnels through a movable chair suspended on the overhead wire rope.

[0003] In actual operation, workers need to perform 2-6 boarding and disembarking operations on overhead passenger vehicles in mines every day. Especially after completing underground work, they are at high risk of falling due to the following factors: (1) Physiological fatigue factors: High-intensity work underground (8-10 hours on average) leads to accumulated muscle fatigue of workers, which reduces their ability to protect themselves when riding; (2) Environmental factors: Dim lighting in the tunnel (average illumination ≤30lux) and constant low-frequency mechanical noise (65-75dB) can easily cause fatigue. As a result, workers are prone to falling off the monkey car due to drowsiness when riding, especially when riding after get off work. In recent years, many falling accidents have occurred. Although various regulations have been made in the mine safety system, there are still cases of inadequate implementation in reality. Production safety cannot rely too much on the subjective safety awareness of workers.

[0004] In addition, the emergency brake device of the mine overhead passenger device is usually installed near the wall in the passage. When an accident occurs in the mine overhead passenger device, such as a worker falling or getting stuck, nearby workers must immediately get off the vehicle and go to the nearby emergency brake device to close the mine overhead passenger device. The operation time is long and the mine overhead passenger device cannot be braked in time, which can easily cause greater injuries.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6 The present invention provides a technical solution: a high-safety anti-falling personnel transportation auxiliary device for underground mines, comprising a main pole 1 connected to a rope gripper on an overhead passenger device of a mine, and a seat plate 2 for riding is fixedly arranged on the lower outer side of the main pole 1. A fixed pole 4 is fixedly arranged on the surface of the side away from the seat plate 2 on the outer side of the middle part of the main pole 1, and the fixed pole 4 is perpendicular to the main pole 1. A cross bar 6 is fixedly arranged on the end of the fixed pole 4, and the cross bar 6, the fixed pole 4 and the main pole 1 are all perpendicular to each other.

[0023] The bottom end of the main rod 1 is inclined toward a side away from the seat plate 2, and two footrests 3 are symmetrically arranged on both sides of the bottom end of the main rod 1 for placing feet on the seat to ensure the safety of the transportation process.

[0024] The outer peripheral surface of the pedal 3 is evenly provided with anti-skid strips, the height of which is 10-20 mm, and the maximum spacing is 20-30 mm, so as to improve the surface friction of the pedal 3 and effectively prevent slipping accidents.

[0025] Two handles 5 are symmetrically arranged on the two side surfaces of the fixed rod 4, and the handles 5 are arranged between the cross rod 6 and the main rod 1. When the operator rides on the mine overhead passenger device, he can either hold the main rod 1 or hold the handles 5 with both hands to fix the body, thereby further improving the safety of the riding process.

[0026] The internal rotation of the cross bar 6 is provided with a coaxial rotating shaft 7, and the two ends of the rotating shaft 7 pass through the two ends of the cross bar 6 and are respectively connected to a rotating protection frame 8. The two rotating protection frames 8 are fixedly provided with a rear side protection rod 9 at one end away from the rotating shaft 7. The rotating protection frame 8 and the rear side protection rod 9 form a C-shaped structure, which can protect the whole body of the operator in conjunction with the main rod 1 to prevent the operator from falling from the mine overhead passenger device due to drowsiness, exhaustion, fainting, etc., causing accidents, thereby greatly improving the safety of the operation of the mine overhead passenger device.

[0027] The end of the handle 5 extends to the outside of the rotating protective frame 8. A slot 10 corresponding to the handle 5 is provided on the lower surface of the rotating protective frame 8. When the protective frame 8 falls, it can be stuck on the end of the handle 5 through the slot 10. The handle 5 can not only allow the operator to hold it to improve the safety of riding, but also can be used to limit and fix the rotating protective frame 8.

[0028] According to a preferred technical solution, a baffle 11 is fixedly provided on the outer surface of the end of the handle 5. The baffle 11 is provided between the rotating protective frame 8 and the fixed rod 4. The highest point of the baffle 11 is higher than the highest point when the rotating protective frame 8 falls. The baffle 11 is used to prevent the operator from placing his hand on the end of the handle 5 and being hit by the falling rotating protective frame 8.

[0029] According to the preferred technical solution, a fixing device for fixing a rotating protection frame 8 and a rear protection bar 9 is installed on the upper part of the main pole 1. When the mine overhead passenger device is running without load, the rotating protection frame 8 and the rear protection bar 9 are fixed on the upper side by the fixing device on the upper part of the main pole 1, without affecting the operators getting on and off the vehicle.

[0030] Specifically: the fixing device includes a fixing cylinder 13 installed on the outer side of the upper part of the main rod 1, and a fixing seat 14 is installed on the side surface of the fixing cylinder 13 close to the seat plate 2. The side surface of the fixing seat 14 is provided with a groove corresponding to the rear side protection rod 9, and a clamping block 12 is fixedly provided in the middle of the upper surface of the rear side protection rod 9, and a clamping groove 15 matching the clamping block 12 is provided in the groove. Before getting off the vehicle, the operator can push the rotating protection frame 8 upward and push the rear side protection rod 9 into the groove, so that the clamping block 12 on the rear side protection rod 9 is clamped into the clamping groove 15 of the groove, and fix it in the groove of the fixing seat 14, so that the operator can get off the vehicle quickly without affecting the next ride.

[0031] Furthermore, the cross-sectional shape of the card block 12 is T-shaped, and two card plates 17 corresponding to the card block 12 are symmetrically slidingly arranged in the card slot 15. The card plate 17 is connected to the inner surface of the card slot 15 through a spring 16. When the card block 12 enters the card slot 15, its larger top end presses the card plate 17, and the card plate 17 slides to both sides through the spring 16. After the larger top end of the card block 12 enters the space behind the card plate 17, its smaller bottom end moves to the position of the card plate 17. The card plate 17 is reset under the elastic force of the spring 16, and the card block 12 is clamped, thereby fixing the rear side protection bar 9 and the rotating protection frame 8 to the upper side of the main bar 1, so as to facilitate the operators to get on and off the vehicle.

[0032] An electromagnet 18 is also provided in the card slot 15, and an iron block 19 corresponding to the electromagnet 18 is fixedly provided on the end side surface of the card plate 17. When the mine overhead passenger device is running without load, the electromagnet 18 is not energized, and the card plate 17 clamps the card block 12 to fix the rear side protection rod 9 and the rotating protection frame 8; after the operator gets on the vehicle, the human body sensor 21 on the upper surface of the seat plate 2 or the middle part of the main rod 1 or the handle 5 activates the built-in controller on the main rod, and the controller turns on the electromagnet 18, and the electromagnet 18 absorbs the iron block 19, and the iron block 19 drives the card plate 17 to move inward, so that the card block 12 can be released, so that the rear side protection rod 9 and the rotating protection frame 8 automatically fall under the action of gravity, so as to protect the operator and avoid accidents caused by falling or unstable sitting during movement.

[0033] The human body sensor 21 adopts an infrared human body sensor commonly used in the prior art.

[0034] Furthermore, the top surface of the block 12 is provided with rounded corners, so that when the block 12 enters the slot 15 , the two clamping plates 17 are squeezed toward both sides, which makes it easier for the operator to lock and fix the rear protection rod 9 .

[0035] Optionally, a buffer damping grease or a commonly used damping structure is provided between the rotating shaft 7 and the interior of the cross bar 6, so that the rear protection rod 9 and the rotating protection frame 8 can play a buffering role when they fall under the action of gravity, thereby preventing the rear protection rod 9 and the rotating protection frame 8 from falling rapidly and causing harm to the operators. At the same time, it also prevents the rotating protection frame 8 from falling rapidly and causing impact on the handle 5 and accelerating wear, thereby extending the service life of the device.

[0036] Optionally, an anti-accidental-touch emergency brake device is provided on the fixed rod 4. The anti-accidental-touch emergency brake device is installed on the fixed rod, close to the hand placement position of the operator when riding. When an emergency stop is required due to an accident, the mine overhead passenger device can be quickly emergency braked to prevent the device from continuing to run and causing greater damage. At the same time, the anti-accidental-touch emergency brake device has the function of preventing accidental touch, which can avoid unnecessary emergency braking and ensure the stable operation of the mine overhead passenger device.

[0037] Specifically, a mounting groove is provided inside the fixing rod 4, and the emergency brake device for preventing accidental touch is arranged in the mounting groove. The emergency brake device for preventing accidental touch includes a central fixing shaft 34, a rotating disk fixing shaft 33 and a counting sensor 32. The counting sensor 32 is preferably a commonly used electromagnetic counter or Hall sensor, etc. The central fixing shaft 34 and the rotating disk fixing shaft 33 are parallel to the axis of the fixing rod 4.

[0038] A rotating ring 25 and a pawl ring 26 are rotatably arranged on the outside of the central fixed shaft 34, and the rotating ring 25 includes an inner gear ring rotatably arranged on the outside of the pawl ring 26 and a coil spring portion fixedly connected to the inner gear ring. At least two notches are evenly arranged on the edge of the pawl ring 26, and a cavity is opened in the notch. A pawl 27 matching the inner gear ring is rotatably arranged in the cavity, and a compression spring corresponding to the pawl 27 is arranged in the cavity. The compression spring applies force to the pawl 27 to rotate it outward. After the pawl 27 rotates to the outside, it can be stuck in the inner tooth groove of the inner gear ring, so that the rotating ring 25 can drive the pawl ring 26 to rotate synchronously.

[0039] For specific rotation methods, please refer to Figure 5 When the rotating ring 25 rotates clockwise, the pawl 27 is stuck in the inner tooth groove of the inner gear ring, and the pawl ring 26 rotates synchronously with the rotating ring 25; when the rotating ring 25 rotates counterclockwise, the pawl 27 is continuously pressed back to the notch by the inner gear ring. At this time, only the rotating ring 25 can rotate counterclockwise, and the pawl ring 26 will not rotate with it.

[0040] A rope groove is provided on the outer peripheral side of the coiled spring portion of the rotating ring 25. A rope 24 is wound in the rope groove. The end of the rope 24 passes through the outside of the fixed rod 4. The rotating ring 25 can be driven to rotate by pulling the rope 24.

[0041] An annular groove 36 is provided on the side surface of the coil spring portion away from the inner gear ring, and a coil spring 37 is installed in the annular groove 36. A first coil spring slot 35 is provided at the end of the central fixed shaft 34, and a second coil spring slot 38 is provided on the inner surface of the annular groove 36. Both ends of the coil spring 37 are respectively clamped in the first coil spring slot 35 and the second coil spring slot 38. By pulling the pull rope 24, the rotating ring 25 is driven to rotate clockwise, thereby driving the pawl ring 26 to rotate clockwise. During the rotation, the coil spring 37 also deforms with the rotation; after the pull rope 24 is released, the coil spring 37 is reset under the action of elastic potential energy, driving the rotating ring 25 to rotate counterclockwise, and retracting the pull rope 24 into the pull rope groove, while the pawl ring 26 does not rotate counterclockwise.

[0042] A driving gear 28 is fixedly arranged on the side surface of the ratchet ring 26, and the driving gear 28 is also rotatably arranged on the outside of the central fixed shaft 34. A driven gear 29 meshing with the driving gear 28 is rotatably arranged on the outside surface of the rotating disk fixed shaft 33. When the ratchet ring 26 rotates, the driven gear 29 is driven to rotate through the driving gear 28. A rotating disk 30 is installed on the side surface of the driven gear 29, and a counting block 31 corresponding to the counting sensor 32 is fixedly arranged on the side surface of the rotating disk 30. When emergency braking is required, the pull rope 24 is pulled, and when the count of the counting block 31 reaches a certain value, the emergency braking device and the alarm device of the mine overhead passenger device are triggered. When the turntable 30 drives the counting block 31 to rotate, the number of rotations can be detected by the counting sensor 32, and the detected number of rotations can be transmitted to the controller set on the main rod 1 through RS485 or other commonly used data transmission protocols. The controller set on the main rod 1 can be selected as a commonly used PLC controller or a microprocessor such as a single-chip microcomputer, such as a Mitsubishi FX3U series PLC controller or an 80C51 series single-chip microcomputer or an ESP32 series single-chip microcomputer.

[0043] A wireless transmission module, such as a WiFi module or a 5G communication module, is also provided on the main pole 1. The controller is connected to the emergency braking system on the mine overhead passenger device through the wireless transmission module. When the controller determines that the number of rotations of the counting block 31 exceeds the set value (such as 100 times, 200 times, 300 times, etc., which can be set according to the number of teeth of the driving gear 28 and the driven gear 29 and the number of turns that the rope can be rotated each time), the controller sends a corresponding signal to the control system of the mine overhead passenger device to activate the emergency braking system and perform emergency braking on the mine overhead passenger device to deal with emergencies.

[0044] When the operator is riding on the mine overhead passenger device, he cannot get off the vehicle quickly and go to the manually controlled emergency brake button due to the protection of the rotating protective frame 8 and other restricted positions. Therefore, a wireless emergency brake device with an anti-mistouch function is set on the fixed rod 4. When the operator needs to stop the vehicle in an accident or an accident occurs nearby and needs to stop the vehicle urgently or get off the vehicle, he can quickly pull the pull rope 24 to make the rotating ring 25 drive the turntable 30 to rotate quickly through the driving gear 28 and the driven gear 29, and measure the number of rotations through the counting sensor 32, and the controller detects the number of rotations of the turntable 30 according to the preset value, so as to intelligently judge whether the wireless emergency brake device set on the fixed rod 4 is triggered, and the emergency brake system on the mine overhead passenger device is wirelessly remotely controlled to brake the mine overhead passenger device in an emergency, thereby avoiding more dangerous situations. The emergency brake is more convenient and responsive. At the same time, a higher trigger rotation number can be set, and the operator can make the turntable 30 rotate multiple times by pulling the pull rope multiple times, and the number of rotations increases to the trigger value, avoiding the situation where the mine overhead passenger device is braked by mistake by pulling the pull rope once.

[0045] Since the rotating ring 25 can only drive the pawl ring 26 to rotate in one direction, when the rotating ring 25 is reset under the drive of the coil spring 37 to retract the pull rope 24, it will not affect the rotation speed of the pawl ring 26 and will not cause it to rotate or stop. Therefore, the turntable 30 can be rotated multiple times by repeatedly pulling the pull rope 24 back and forth, which greatly reduces the probability of unnecessary emergency braking caused by false triggering and makes the triggering more accurate. Specifically, the number of rotations of the turntable 30 is set to trigger the emergency brake only when the pull rope is pulled twice or more, so as to avoid the emergency brake being triggered by the pull rope 24 being pulled by mistake or the pull rope 24 being accidentally hooked by foreign objects such as when people get off the car, or the situation where people pull the pull rope out of curiosity, etc., which greatly improves the effect of preventing false touches.

[0046] A rechargeable lithium-ion battery can be provided on the main rod 1 to power the controller, the electromagnet 18, the counting sensor 32, the wireless transmission module, etc. Since the electromagnet 18 is in a normally open state, it is only opened once when the rear protection rod 9 is lowered. Therefore, the power consumption of the device is extremely small and can be powered for a long time by providing a battery.

[0047] In addition, the individual electrical components can also be powered by busbar power supply system, conductive rail power supply (equipment draws power through sliding contacts or conductive wheels), flexible drag chain power supply or conductive wheels, etc., according to the specific running length and actual situation of the mine overhead passenger device. When wired power supply is adopted, a camera 20 can be installed on the lower side of the fixed seat 14 to remotely monitor the riding posture of the operator. When it is found that the riding is not standardized or there is drowsiness, the rotating protective frame 8 is not lowered, etc., a reminder can be given through the broadcast in the lane. In addition, it can also play a role of supervision and vigilance, and improve the safety awareness of the operators when riding the mine overhead passenger device.

[0048] The camera 20, controller, electromagnet 18, wireless transmission module and electromagnet 18 used in this application are all electronic components commonly used in the prior art. Their specific structures, working principles, control methods and circuit connections are all well-known technologies and will not be described in detail here.

[0049] Furthermore, a stopper 23 is installed on the upper surface of the fixed rod 4. A through hole communicating with the inner cavity of the fixed rod 4 is opened on the upper surface of the stopper 23. The end of the pull rope 24 passes through the through hole and is fixedly connected to the pull ring 22. The operator pulls the pull rope 24 through the pull ring 22, which is simple to operate and easy to use.

[0050] The undisclosed parts in the present invention are all prior art, and their specific structures, materials and working principles are not described in detail. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
