Description

Technical Field

[0001] This invention relates to the field of mining unmanned vehicle technology, specifically to an anti-collapse braking device for mining unmanned vehicles. Background Technology

[0002] Mining trucks are essential transportation tools in industries such as mining, metallurgy, construction, and chemicals. Their operation is characterized by bumpy roads, short distances, and small mining areas, requiring vehicles to maintain high maneuverability. Due to the harsh working environment, high labor intensity, and poor living conditions in mining areas, it is becoming increasingly difficult to recruit mining truck drivers, leading to a growing demand for driverless mining trucks in recent years.

[0003] Existing mine cars typically operate using pulleys that slide along guide rails. However, due to terrain conditions, these guide rails often have significant turning angles. When a mine car fully loaded with coal or other materials turns, it may tip over, potentially causing an accident. Traditional anti-tipping devices have simple structures and only provide support; they cannot right the mine car once it has tilted at a certain angle, making them very cumbersome to use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an anti-collapse braking device for unmanned mining vehicles, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-collapse braking device for a mining unmanned vehicle, which is installed on the side of the unmanned vehicle body. The unmanned vehicle body travels on a laid track. The device includes multiple columns, multiple traction components, and a processing compartment. The processing compartment is installed inside the unmanned vehicle body, and extends to the outside of the unmanned vehicle body on both sides. The multiple columns are arranged at equal intervals on both sides of the track. A slide rail is provided at the top of the same row of columns. The traction components slide in cooperation with the slide rail. A steel cable extends outward from the traction components and is used to connect to the side of the processing compartment.

[0006] The processing chamber has symmetrical chambers on the left and right sides, and a box is placed in the chamber. Sliding columns are symmetrically arranged on the front and rear sides of the box. The outer ends of the two sliding columns extend into the processing chamber and are connected to connecting strips. The end of the steel cable away from the traction component is connected to the connecting strip.

[0007] A pressure sensor is provided at the outward end of the housing. The housing and the pressure sensor work together to sense whether the unmanned vehicle body tilts during driving. When the unmanned vehicle body tilts, it stops moving forward and uses a traction component to straighten the unmanned vehicle body.

[0008] The processing chamber is equipped with a control module.

[0009] Preferably, the box body has an arc-shaped groove, with the outer end of the arc-shaped groove inclined upwards. A counterweight is slidably fitted inside the box body. A long rod is slidably fitted in the middle section of the arc-shaped groove, and a short rod is slidably fitted in the outer end of the arc-shaped groove. The long rod and the short rod are arranged horizontally. The pressure sensor is connected to two springs, which are respectively connected to the long rod and the short rod. The pressure sensor is electrically connected to the control module.

The beam emitter and the beam receiver are electrically connected to the control module.

[0011] Preferably, the inner wall of the processing chamber is connected to a sleeve, which is fitted over the sliding column. The sleeve has through grooves at equal angles, and the outer surface of the sleeve has a groove between two adjacent through grooves. The outer surface of the sliding column is connected to a protrusion, which slides in cooperation with the through groove. A pulley is pivotally connected between two adjacent protrusions, and the pulley slides in cooperation with the groove.

[0012] Preferably, the sliding rod body has an insertion hole, and a medium electric push rod is connected to the inner wall of the processing chamber. The medium electric push rod can be extended to pass through the insertion hole.

[0013] Preferably, the traction assembly includes a slider, a take-up roller, an iron block, and a drive wheel. The slider is slidably engaged with a slide rail, the take-up roller is positioned on the side of the slider facing the processing chamber, the end of the steel cable away from the processing chamber is connected to the take-up roller, the iron block is positioned on the side of the slider away from the processing chamber, and the drive wheel is connected to the iron block.

[0014] Preferably, the column is inlaid with a vertical large electric actuator, the top of which is connected to a large electromagnet module. When the large electric actuator is extended to its longest length, the top of the large electromagnet module is flush with the bottom of the inner wall of the slide rail. The upper and lower sides of the slide rail and the top of the large electromagnet module are provided with flanges, and the slider is provided with slots corresponding to the flanges.

[0015] Preferably, a GPS locator is connected to the top of the slider, and a signal transmitter is connected to the side of the unmanned vehicle body, and the signal emitted by the signal transmitter can be received by the GPS locator.

[0016] Preferably, the bottom of the box is provided with a through groove, which is connected to an arc-shaped groove. A long rod passes through the through groove and enters the arc-shaped groove. A small electric push rod is connected to the bottom of the inner wall of the processing chamber, which is used to support the long rod.

[0017] Preferably, the processing chamber is embedded with a small electromagnet module, which corresponds one-to-one with the sliding column. A magnetic rod is placed on the protrusion, and the magnetic rod can be affected by the magnetic force of the small electromagnet module.

[0018] This invention provides an anti-tipping braking device for unmanned mining vehicles. It has the following beneficial effects: 1. The anti-tipping braking device of this mining unmanned vehicle consists of a housing, counterweight, long rod, red glass plate, short rod, pressure sensor, spring, and traction assembly. The device determines if the unmanned vehicle is tipping over based on whether the counterweight applies force to the short rod. Then, through the cooperation of sliding columns, magnetic rods, and small electromagnet modules, the device supports the unmanned vehicle and prevents it from tilting further. The traction assembly is located on both sides of the unmanned vehicle. By applying force in the opposite direction to the vehicle's tilt, the traction assembly rights the vehicle, thus preventing it from tipping over and restoring it to its original position.

[0019] 2. The anti-tipping braking device of the mining unmanned vehicle consists of columns erected on both sides of the unmanned vehicle, with tracks on the columns. The traction component slides within the tracks. Large electric actuators and large electromagnet modules are installed on the sides of the columns.

[0022] This invention provides an anti-tipping braking device for an unmanned mining vehicle, such as... Figure 1-8 As shown, the components are arranged on the side of the unmanned vehicle body 1, which travels on the laid track 2. The track includes multiple columns 3, multiple traction components, and a processing chamber 4. The processing chamber 4 is fixedly installed inside the unmanned vehicle body 1, extending to the outside of the unmanned vehicle body 1 on both sides. Multiple columns 3 are fixedly installed at equal intervals on both sides of the track 2. A slide rail 31 is fixedly installed on the top of each row of columns 3. The traction components slide in conjunction with the slide rail 31. Steel cables 92 extend outward from the traction components and are used to connect to the sides of the processing chamber 4. The aforementioned traction components are symmetrically arranged on both sides of the unmanned vehicle body 1.

[0023] The processing chamber 4 has symmetrical chambers on the left and right sides. A box 5 is fixedly installed in the chamber. Sliding columns 7 are symmetrically arranged on the front and rear sides of the box 5. The outer ends of the two sliding columns 7 extend to the processing chamber 4 and are welded with connecting strips 71. The end of the steel cable 92 away from the traction component is welded to the connecting strip 71.

[0024] A pressure sensor 6 is installed at the outward-facing end of the housing 5, and the pressure sensor 6 is fixedly installed to the inner wall of the processing chamber 4. The housing 5 and the pressure sensor 6 work together to detect whether the unmanned vehicle body 1 tilts during operation. When the unmanned vehicle body 1 tilts, it stops moving forward, and a traction component is used to right it. For example, when the unmanned vehicle tilts to the left, the traction component located on the right side of the unmanned vehicle activates, pulling the unmanned vehicle to the right, thereby preventing it from tilting further and achieving the purpose of righting the unmanned vehicle.

[0025] A control module is fixedly installed in the fourth chamber of the processing compartment. The control module controls the operation of electronic components. Since this is a conventional technical method, it will not be described in detail.

[0026] An arc-shaped groove 51 is provided inside the housing 5. The outer end of the arc-shaped groove 51 is inclined upward. A counterweight 52 is slidably fitted inside the housing 5. A long rod 53 is slidably fitted in the middle section of the arc-shaped groove 51. A short rod 54 is slidably fitted in the outer end of the arc-shaped groove 51. The long rod 53 and the short rod 54 are arranged horizontally. Two springs 61 are fixedly installed on the pressure sensor 6. The two springs 61 are fixedly connected to the long rod 53 and the short rod 54 respectively. The pressure sensor 6 is electrically connected to the control module.

[0027] A beam emitter 41 is fixedly installed on the top of the inner wall of the processing chamber 4, and a beam receiver 42 is fixedly installed on the bottom of the inner wall of the processing chamber 4. The beam emitter 41 and the beam receiver 42 are aligned with each other, and the beam emitter 41 emits white light towards the beam receiver 42.

[0028] The long rod 53 has a hole at one of its outward-facing ends, and a red glass plate 531 is embedded in the hole. The beam emitter 41, the beam receiver 42 and the control module are electrically connected.

[0029] A sleeve 8 is welded to the inner wall of the processing chamber 4. The sleeve 8 is fitted over the sliding column 7. The sleeve 8 has through grooves 81 at equal angles. A groove 82 is formed on the outer surface of the sleeve 8 between two adjacent through grooves 81. A protrusion 73 is welded to the outer surface of the sliding column 7. The protrusion 73 slides with the through groove 81. A pulley 75 is pivotally connected between two adjacent protrusions 73. The pulley 75 slides with the groove 82.

[0030] Small electromagnet modules 45 are embedded inside the processing chamber 4, each corresponding to a sliding post 7. A magnetic rod 74 is mounted on the protrusion 73, and the magnetic rod 74 is affected by the magnetic force of the small electromagnet modules 45. When current flows in the forward direction through the small electromagnet modules 45, a repulsive force is generated between the magnetic rod 74 and the small electromagnet modules 45. When current flows in the reverse direction through the small electromagnet modules 45, a mutually attractive force is generated between the magnetic rod 74 and the small electromagnet modules 45.

[0031] The slide rod 7 has an insertion hole 72, and the processing chamber 4 has a medium electric push rod 44 fixedly installed on the inner wall of the chamber. The medium electric push rod 44 can be extended to pass through the insertion hole 72.

[0032] Working principle: If the unmanned vehicle tilts to the left, the counterweight 52 inside the left-side housing 5 moves along the arc-shaped groove 51 due to its own weight. The counterweight 52 first pushes the long rod 53, which moves outward, positioning the red glass plate 531 in the beam receiver 42. The light emitted from the beam emitter 41 passes through the red glass plate 531, turning into red light, which then shines on the beam receiver 42. The beam receiver 42 feeds the information back to the control module. The control module then controls the retraction of the electric push rod 44, which is pulled out of the socket 72, allowing the sliding column 7 to move. Simultaneously, the small electromagnet module 45 and the magnetic rod 74 generate a repulsive force, causing the sliding column 7 to extend from inside the housing 4 and contact the ground. The sliding column 7 supports the unmanned vehicle, preventing it from tilting further.

[0033] Next, the counterweight 52 comes into contact with the short rod 54 via the long rod 53. The counterweight 52 presses against the short rod 54. After the pressure sensor 6 senses the pressure, it feeds the information back to the control module. The control module then operates the traction component on the right side via wireless remote control to pull the unmanned vehicle back and straighten it.

[0034] The traction assembly includes a slider 9, a take-up roller 91, an iron block 95, and a drive wheel 96. The slider 9 is slidably engaged with the slide rail 31. The take-up roller 91 is driven by a motor and is fixedly installed on the side of the slider 9 facing the processing chamber 4. The end of the steel cable 92 away from the processing chamber 4 is welded to the take-up roller 91. The iron block 95 is fixedly installed on the side of the slider 9 away from the processing chamber 4. The drive wheel 96 is fixedly installed together with the iron block 95.

[0035] The column 3 is inlaid with a vertical large electric actuator 32. A large electromagnet module 33 is fixedly installed on the top of the large electric actuator 32. When the large electric actuator 32 is extended to its longest length, the top of the large electromagnet module 33 is flush with the bottom of the inner wall of the slide rail 31. There are flanges on the upper and lower sides of the slide rail 31 and the top of the large electromagnet module 33. The slider 9 has a slot 94 corresponding to the flange. The flange and the slot 94 slide together.

[0036] Working principle: If the unmanned vehicle tilts to the left, the left sliding column 7 unlocks and supports the vehicle body. The traction components on both sides of the vehicle body slowly move, causing the slider 9 to move above the nearest large electromagnet module 33. The right traction component then operates, with the winding roller 91 rotating to wind the steel cable 92. Simultaneously, the large electromagnet module 33 is energized to attract the iron block 95, and the large electric push rod 32 retracts, causing the entire slider 9 to move downwards. This applies force to the right side of the unmanned vehicle, tilting it to the right and ultimately straightening it.

[0037] A GPS locator 93 is fixedly installed on the top of the slider 9, and a signal transmitter is fixedly installed on the side of the unmanned vehicle body 1. The signal emitted by the signal transmitter can be received by the GPS locator 93. By cooperating with the GPS locator 93, the slider 9 can follow the unmanned vehicle and promptly transmit the location of the accident to the outside world when the unmanned vehicle has an accident.

[0038] The bottom of the box 5 has a through groove 511, which is connected to the arc groove 51. The long rod 53 passes through the through groove 511 and enters the arc groove 51. A small electric push rod 43 is fixedly installed on the bottom of the inner wall of the processing chamber 4. The small electric push rod 43 is used to support the long rod 53.

[0039] Working principle: When the unmanned vehicle is straightened again, the counterweight 52 moves back to its original position. At this time, the small electric push rod 43 retracts, and the long rod 53 can move up and down, thereby preventing the counterweight 52 from being stuck by the long rod 53.

[0040] In summary, the anti-tipping braking device of this mining unmanned vehicle comprises a housing 5, a counterweight 52, a long rod 53, a red glass plate 531, a short rod 54, a pressure sensor 6, a spring 61, and a traction assembly. The device determines whether the unmanned vehicle is tipping over based on whether the counterweight 2 applies force to the short rod 54. Then, through the cooperation of the sliding column 7, the magnetic rod 74, and the small electromagnet module 45, the unmanned vehicle is supported, preventing further tilting. The traction assembly is located on both sides of the unmanned vehicle. By applying force in the opposite direction to the tilt of the unmanned vehicle, the traction assembly uprights the vehicle, achieving the purpose of preventing tipping and restoring the unmanned vehicle to its original position.

[0041] Furthermore, pillars 3 are erected on both sides of the unmanned vehicle, and tracks 2 are erected on the pillars 3. The traction component slides within the tracks 2. Large electric push rods 32 and large electromagnet modules 33 are provided on the sides of the pillars 3. The traction component consists of a slider 9, a take-up roller 91, a steel cable 92, an iron block 95, and a drive wheel 96. The steel cable 92 connects the slider to the unmanned vehicle. The take-up roller 91 rotates and winds the steel cable 92. The large electric push rods 32 and large electromagnet modules 33 work to make the slider 9 descend, thereby applying force in the opposite direction to the tilt of the unmanned vehicle and achieving the purpose of straightening the unmanned vehicle.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
