Description

Technical Field

[0001] This invention relates to the field of mine safety technology, and in particular to a mine road boundary generation and display device. Background Technology

[0002] Mining roads refer to the roads within a mining area used to transport ore to the outside world. Compared to urban roads, mining environments are enclosed, and the roads and traffic rules are self-contained. There are no public roads or simple compacted surfaces for vehicles to travel on. Among them, the most common type is the spiral mining road, which relies on the mining area to create a spiral downward road surface until vehicles can travel on level ground. The road ends based on a spiral structure, with an upward-extending slope on the outer side and a downward-extending slope on the inner side leading into the mine pit.

[0003] Since the roads in the mining area have not been constructed to urban road standards, and the road surface and roadbed are damaged by heavy trucks, potholes and other problems are likely to occur. Furthermore, mining operations affect the surrounding geographical structure, which can also cause instability in the mining area roads. Therefore, road boundary information display devices can serve as warnings and provide auxiliary guidance when driving through the mine pit to the level ground section.

[0004] Existing road boundary information display devices are mostly display screens or banners. Mining areas are open and remote, and the roads have not undergone regular urban maintenance. This makes it easy for dust to accumulate on the surface of the display screens during snowy weather and excessive vehicle dust, affecting the content and clarity of the information displayed. In view of this, we propose a road boundary generation and display device for mining areas. Summary of the Invention

[0012] Preferably, the cleaning rod is arranged at the end of the swing gear shaft; and the outer surface of the cleaning rod is uniformly provided with rubber protrusions; and each of the rubber protrusions is provided with an electric heating wire.

[0013] A method for using a mining area road boundary generation and display device includes the following steps: S100 Installation Process: Multiple road boundary generation display devices for the mining area are installed at both ends and the middle of the road using column installation devices; to display information and provide warnings to passing vehicles. S200: Display adjustment processing: S201: Under normal display and warning conditions, the flip servo motor can drive the reducer A to input high torque power, synchronously driving the flip bevel gear B to rotate, causing the fixed display screen and the movable display screen components to unfold relative to each other. S202: In rainy or snowy weather conditions, the servo motor can drive the reducer A to input high torque power, which synchronously drives the rotating bevel gear B to rotate, causing the fixed display screen and the movable display screen components to fold closer together. S300: Cleaning process: For daily dust cleaning of the S201 display: The servo motor drives the reducer B to rotate the drive bevel gear A, and also inputs power to the swing arm A at the output end of the reducer B, causing the swing arm A to rotate around the output end of the reducer B. Simultaneously, under the radial limitation of the limiting slide groove, the reciprocating linear movement mechanism moves linearly back and forth under the drive of the swing arm B. At the same time, the reducer B drives the two drive bevel gears B to rotate synchronously, driving the chain, which in turn drives the output gear disc to rotate synchronously, causing the threaded shaft to rotate. Based on the spiral meshing adjustment groove and meshing protrusion on the threaded shaft, the drive... The movable adjustment slider is close to the reciprocating linear movement mechanism; and with the setting of the idle groove, after the meshing protrusion is located at the end of the meshing adjustment groove, the cleaning drive component continues to move in the same direction, and can perform circumferential rotation in the idle groove; when the cleaning drive component rotates relatively forward to input power, the two drive adjustment sliders are brought closer to each other, so that when the sliding seat reciprocates linearly to the farthest ends on both sides, the extended contact shaft can contact the force-bearing protrusion, so that the adjustment crank teeth are rotated as a whole. The rotation of the adjustment crank teeth is used to drive the swing gear shaft to drive the cleaning rod to perform flipping action and linear movement, and to clean the floating dust on the surface of the fixed display screen and the movable display screen components. To clear snow and ice accumulation in rainy / snowy weather on S202: The servo motor drives the reducer B to rotate the drive bevel gear A, and also inputs power to the swing arm A at the output end of reducer B. This causes the swing arm A to rotate around the output end of reducer B. Simultaneously, under the radial limit of the limiting slide groove, the reciprocating linear movement mechanism moves linearly back and forth under the drive of the swing arm B. Simultaneously, the reducer B drives the two drive bevel gears B to rotate synchronously, driving the chain, which in turn drives the output gear plate to rotate synchronously, causing the threaded shaft to rotate. Based on the spiral meshing adjustment groove on the threaded shaft connecting to the meshing protrusion, the drive adjustment slider is driven to move away from the reciprocating linear movement mechanism. When the sliding seat reciprocates linearly to its farthest point on both sides, the extended contact shaft cannot contact the force-bearing protrusion, maintaining a single linear reciprocating motion. This allows for the heat-melting and cleaning of snow and ice accumulation in the gaps between the fixed and movable display screen components after folding.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a combined cleaning system to move a cleaning rod to clean the outer surface of the fixed and movable display screen components. This effectively removes dust and snow accumulation caused by rain or snow from the outer surface of the fixed and movable display screen components, thus reducing the impact on the content and clarity of the information displayed.

[0015] 2. This invention uses a servo motor to drive a reducer A to input high torque, which synchronously drives a rotating bevel gear B to rotate. This causes the rotating bevel gear A and the movable display screen assembly to rotate relative to the fixed display screen. This arrangement allows the display device to have a folded state and an unfolded state. In the folded state, road information is obscured, which is suitable for use when roads are slippery and transportation is stopped in snowy weather. At the same time, it reduces the possibility of snow directly covering the fixed display screen and the movable display screen assembly. In the unfolded state, information guidance can be displayed in normal weather.

[0016] 3. The present invention, through the arrangement of the top contact block A and the spring A, causes the movable end of the spiral idling assembly to be driven synchronously to approach the top contact block A, causing the spring A to be compressed, and causing the top contact block A to retract into the elastic movable cavity A. At this time, based on the compression of the spring A, the top contact block A synchronously has an outward restoring force, which improves the engagement success rate and engagement stability required for the engagement adjustment movement of the movable end of the spiral idling assembly.

[0017] 4. This invention drives the servo motor to output power, causing the reducer B to drive the bevel gear A to rotate, and inputs power to the swing arm A at the output end of the reducer B, causing the swing arm A to rotate around the output end of the reducer B. Simultaneously, under the radial limitation of the limiting groove, the reciprocating linear movement mechanism performs linear reciprocating movement under the drive of the swing arm B. At the same time, based on the drive of the reducer B, the two drive bevel gears B rotate synchronously. This setting enables the synchronous and efficient driving of the two helical idler components.

[0018] 5. This invention, through the chain arrangement, causes the output gear disc to synchronously drive the input adjustment gear disc to rotate, resulting in the rotation of the threaded shaft. Based on the helical meshing adjustment groove and meshing protrusion on the threaded shaft, the drive adjustment slider is driven to move away from or towards the reciprocating linear movement mechanism. Furthermore, the idling groove allows the meshing protrusion to have circumferential rotational space when the sweeping drive assembly continues to move in the same direction after the meshing adjustment groove is located at its end, thus avoiding motion interference and ensuring smooth sweeping operation. The top block B and spring B are arranged such that when the two drive adjustment sliders move away from each other, the top block B compresses the spring B, causing the spring B to compress and apply an outward force to the top block B, improving the success rate and stability of meshing for the movable end of the helical idling assembly to mesh and adjust. The synchronous adjustment of the two drive adjustment sliders by the relative forward and reverse rotation of the drive servo motor further adjusts the reciprocating linear movement mechanism, enabling switching between directional sweeping and unidirectional snow melting states.

[0019] 6. This invention, based on the power input of the cleaning drive component, allows the sliding seat to slide linearly along the limiting groove. In the directional scraping state, the cleaning drive component rotates relatively forward to input power, causing the two drive adjustment sliders to move closer together. When the sliding seat reciprocates linearly to the farthest ends on both sides, the extended contact shaft can contact the force-bearing protrusion, causing the adjusting crank teeth to rotate. The rotation of the adjusting crank teeth drives the swing gear shaft to flip, which can be used to scrape away floating dust from the fixed and movable display screen components in the unfolded state. When the cleaning drive component rotates relatively in the opposite direction to input power, the two drive adjustment sliders move away from each other. When the sliding seat reciprocates linearly to the farthest ends on both sides, the extended contact shaft cannot contact the force-bearing protrusion, allowing a single reciprocating linear motion between the fixed and movable display screen components in the folded state to remove snow and ice that has been immersed between the fixed and movable display screen components.

[0020] 7. This invention utilizes rubber protrusions to facilitate the cleaning of surface dust from the fixed and movable display screen components, and incorporates electric heating wires to facilitate snow melting and de-icing operations.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A device for generating and displaying road boundaries in a mining area, see [link / reference] Figures 1 to 7The system includes a support frame 1, a fixed display screen 2, a movable display screen assembly 3, a combined cleaning system 9, and a folding control assembly 10. The internal gap of the support frame 1 forms an operating cavity. The fixed display screen 2 is fixed to the high end of the operating cavity. The movable display screen assembly 3 is hinged to the low end of the operating cavity. One end of the movable display screen assembly 3 is equipped with a flipping bevel gear A. The combined cleaning system 9 is located in the middle of the operating cavity. The folding control assembly 10 is located on one side of the support frame 1 and connected to the movable display screen assembly 3. The combined cleaning system 9 includes an axial sliding frame assembly 4, a cleaning drive assembly 5, a spiral idler assembly 6, a reciprocating linear movement mechanism 7, and a cleaning rod 8. The axial sliding frame assembly 4 is fixed to the middle of the operating cavity. The cleaning drive assembly 5 is located on the side of the axial sliding frame assembly 4 away from the movable display screen assembly 3. Two spiral idler assemblies 6 are symmetrically arranged at both ends of the axial sliding frame assembly 4 and connected to the cleaning drive assembly 5. The reciprocating linear movement mechanism 7 is movably arranged on the axial sliding frame assembly 4. The cleaning rod 8 is arranged on the reciprocating linear moving mechanism 7. The combined cleaning system 9 has a directional scraping state and a one-way snow melting state. In the directional scraping state of the combined cleaning system 9, the cleaning drive component 5 rotates to drive the reciprocating linear moving mechanism 7 to move back and forth, and simultaneously drives the movable ends of the two spiral idling components 6 to move closer to each other. This causes the reciprocating linear moving mechanism 7 to drive the cleaning rod 8 to swing 180 degrees while moving back and forth, forming a dust scraping cleaning structure for cleaning the surface dust of the fixed display screen 2 and the movable display screen component 3 in the unfolded state. In the one-way snow melting state of the combined cleaning system 9, the cleaning drive component 5 rotates in the opposite direction to drive the reciprocating linear moving mechanism 7 to move back and forth, and simultaneously drives the movable ends of the two spiral idling components 6 to move further apart. This causes the reciprocating linear moving mechanism 7 to drive the cleaning rod 8 to move back and forth, forming a snow melting and heating cleaning structure for the surface snow of the fixed display screen 2 and the movable display screen component 3 in the folded and closed state. This invention uses the combined cleaning system 9 to move the cleaning rod 8 to clean the outer surfaces of the fixed display screen 2 and the movable display screen assembly 3. This cleans the dust and snow accumulated on the outer surfaces of the fixed display screen 2 and the movable display screen assembly 3, effectively reducing the impact on the content and clarity of the information displayed.

[0023] Specifically, the folding control component 10 includes a flip servo motor 1001 and a reducer A; the flip servo motor 1001 is arranged on one side of the support frame 1 via a mounting bracket A; and the output end of the flip servo motor 1001 is provided with a reducer A; the output end of the reducer A is provided with a flip bevel gear B; wherein the flip bevel gear B is meshed with the flip bevel gear A. This invention allows the flip servo motor 1001 to drive the reducer A to provide high-torque power input, synchronously driving the flip bevel gear B to rotate, thereby causing the flip bevel gear A and the movable display screen component 3 to rotate relative to the fixed display screen 2. This arrangement allows the display device to have both a folded and an unfolded state. In the folded state, road information is obscured, adapting to the situation where transportation is suspended due to slippery roads in snowy weather, while also reducing the direct coverage of snow onto the fixed display screen 2 and the movable display screen component 3. In the unfolded state, information guidance can be displayed in normal weather.

[0024] Furthermore, the axial sliding frame assembly 4 includes a central axis slide frame body 401 and a top connecting block A402; the central axis slide frame body 401 is arranged in the middle of the operating cavity through several support shafts; a drive auxiliary groove 4011 is provided on one side of the outer wall of the central axis slide frame body 401; and a limiting groove 4012 is provided on the other side of the outer wall of the central axis slide frame body 401 opposite to the drive auxiliary groove 4011; the limiting groove 4012 is trapezoidal in shape; and adjustment grooves 4013 are provided on both sides of the surface of the central axis slide frame body 401 opposite to the drive auxiliary groove 4011; the two adjustment grooves 4013 and the limiting grooves 4012 are separated by two partition blocks 4014; and at least one elastic movable cavity A is provided on the opposite side of each of the two partition blocks 4014; the top connecting block A402 is arranged in the elastic movable cavity A by a spring A. The present invention, through the arrangement of the top contact block A402 and the spring A, causes the movable end of the spiral idling assembly 6 to be driven synchronously to approach the top contact block A402, causing the spring A to be compressed, so that the top contact block A402 retracts into the elastic movable cavity A. At this time, based on the compression of the spring A, the top contact block A402 synchronously has an outward restoring force, which improves the engagement success rate and engagement stability of the movable end of the spiral idling assembly 6 for engagement adjustment and movement.

[0025] Furthermore, the cleaning drive assembly 5 includes a drive servo motor 501, a drive bevel gear B503, an output gear 504, a swing arm A505, and a swing arm B506; the drive servo motor 501 is arranged on the side of the axial sliding frame assembly 4 away from the movable display screen assembly 3; and the drive servo motor 501 is arranged on the support frame 1 via the mounting component B; and a reducer B is provided at the output end of the drive servo motor 501; the output end of the reducer B is provided with a drive bevel gear A502; and the output end of the reducer B passes through the drive bevel gear. Inside A502; two drive bevel gears B503 are symmetrically arranged inside the operating cavity via support seats; and the two drive bevel gears B503 are meshed with drive bevel gear A502; each drive bevel gear B503 has a drive shaft passing through it; the output gear 504 is arranged at the end of the drive shaft; the rocker arm A505 is arranged at the output end of the reducer B; the rocker arm B506 is hinged to the end of the rocker arm A505; and the end of the rocker arm B506 is provided with a hinged connecting shaft 5061 extending into the limiting slide groove 4012. This invention drives the servo motor 501 to output power, causing the reducer B to drive the bevel gear A502 to rotate, and also inputs power to the swing arm A505 at the output end of the reducer B, causing the swing arm A505 to rotate around the output end of the reducer B. Simultaneously, under the radial limitation of the limiting groove 4012, the reciprocating linear movement mechanism 7 performs linear reciprocating movement under the drive of the swing arm B506. At the same time, based on the drive of the reducer B, the two drive bevel gears B503 rotate synchronously. This arrangement enables the synchronous and efficient driving of the two helical idler components 6.

[0026] It is worth noting that the spiral idling assembly 6 includes a threaded shaft 601, an input adjusting gear 602, a drive adjusting slider 603, and a top contact block B604; the threaded shaft 601 is arranged in the adjusting groove 4013; and the surface of the threaded shaft 601 is provided with a spiral meshing adjusting groove and two symmetrically distributed annular idling grooves; wherein, the meshing adjusting groove and the idling groove are connected; the input adjusting gear 602 is arranged on the same vertical axis as the threaded shaft 601 and opposite to the output gear 504; and the input adjusting... The gear disc 602 is connected to the output gear disc 504 via a chain; the drive adjustment slider 603 is arranged on the threaded shaft 601; and the drive adjustment slider 603 has at least one meshing protrusion 6031 inside; wherein, each of the two drive adjustment sliders 603 has at least one elastic movable cavity B on its opposing surface; wherein, each of the two drive adjustment sliders 603 has an extension shaft at one end of its opposite surface; and the extension shaft has a force-bearing protrusion 6032; the top block B604 is arranged in the elastic movable cavity B via a spring B. This invention, through the chain arrangement, causes the output gear disk 504 to synchronously drive the input adjustment gear disk 602 to rotate, resulting in the rotational movement of the threaded shaft 601. Based on the helical meshing adjustment groove on the threaded shaft 601 connected to the meshing protrusion 6031, the drive adjustment slider 603 is driven to move away from or closer to the reciprocating linear movement mechanism 7. Furthermore, by utilizing the idle slot, when the meshing protrusion 6031 is located at the end of the meshing adjustment groove and the cleaning drive assembly 5 continues to move in the same direction, the meshing protrusion 6031 has space for circumferential rotation, thus avoiding motion interference and ensuring the smoothness of stable cleaning operation. By using the top contact block B604 and spring B, the top contact block B604 compresses the spring B as the two drive adjustment sliders 603 move away from each other. This causes the spring B to compress and apply an outward compressive force to the top contact block B604, improving the engagement success rate and engagement stability of the movable end of the spiral idling assembly 6. Furthermore, by using the drive servo motor 501 to synchronously adjust the relative forward and reverse rotation of the two drive adjustment sliders 603 to move away or closer to each other, the reciprocating linear movement mechanism 7 can be further adjusted to achieve the switching between directional scraping mode and unidirectional snow melting mode.

[0027] It is worth noting that the reciprocating linear movement mechanism 7 includes a sliding seat 701, a swing gear shaft 702, and an adjusting crank gear 703; the sliding seat 701 is slidably arranged on the limiting slide groove 4012 and connected to the hinge connecting shaft 5061; wherein, the sliding seat 701 is rotatably connected to the rocker arm B506 through the hinge connecting shaft 5061; the swing gear shaft 702 is movably arranged on the side of the sliding seat 701 that is relatively far away from the limiting slide groove 4012; the adjusting crank gear 703 is arranged on one side of the swing gear shaft 702 and connected to the sliding seat 701; and the sliding seat 701 and the adjusting crank gear 703 are rotatably connected; wherein, the adjusting crank gear 703 is meshed with the swing gear shaft 702; wherein, the adjusting crank gear 703 is provided with an extension contact shaft 7031 on the side relatively close to the force-bearing protrusion 6032. This invention, based on the power input of the sweeping drive assembly 5, enables the sliding seat 701 to slide linearly along the limiting groove 4012. In the directional sweeping state, the sweeping drive assembly 5 rotates relatively forward to input power, causing the two drive adjustment sliders 603 to move closer together. When the sliding seat 701 reciprocates linearly to its farthest points on both sides, the extending contact shaft 7031 contacts the force-bearing protrusion 6032, causing the adjusting crank gear 703 to rotate. The rotation of the adjusting crank gear 703 drives the swing gear shaft 702 to perform a flipping action. The fixed display screen 2 and the movable display screen assembly 3 in the unfolded state are treated by scraping away the floating dust; and when the cleaning drive assembly 5 rotates in the opposite direction to input power, the two drive adjustment sliders 603 are moved away from each other; when the sliding seat 701 slides back and forth linearly at the farthest ends on both sides, the extension contact shaft 7031 cannot contact the force-bearing protrusion 6032, and a single reciprocating linear motion can be performed between the fixed display screen 2 and the movable display screen assembly 3 in the folded state to remove the snow and ice that have been immersed between the fixed display screen 2 and the movable display screen assembly 3.

[0028] It is worth mentioning that the cleaning rod 8 is arranged at the end of the swing gear shaft 702; and the outer surface of the cleaning rod 8 is uniformly provided with rubber protrusions; and each of the rubber protrusions is provided with an electric heating wire. The present invention uses the rubber protrusions to facilitate the cleaning of floating dust on the surface of the fixed display screen 2 and the movable display screen assembly 3, and at the same time, the electric heating wires facilitate the heating for snow melting and de-icing operations.

[0029] Example 2: A method for using a mining area road boundary generation and display device, comprising the following steps: S100: Installation Process: Multiple road boundary generation display devices for the mining area are installed at both ends and the middle of the road using a column installation device; to display information and provide warnings to passing vehicles. S200: Display adjustment processing: S201: Under normal display and warning conditions, the high torque power input of the reducer A can be driven by the flip servo motor 1001, which synchronously drives the flip bevel gear B to rotate, causing the fixed display screen 2 and the movable display screen assembly 3 to unfold relative to each other. S202: In rainy or snowy weather conditions, the servo motor 1001 can drive the reducer A to input high torque power, and synchronously drive the rotating bevel gear B to rotate; causing the fixed display screen 2 and the movable display screen assembly 3 to fold closer together. S300: Cleaning process: For daily dust cleaning of S201: The servo motor 501 drives the reducer B to rotate the drive bevel gear A502, and also inputs power to the swing arm A505 at the output end of the reducer B, causing the swing arm A505 to rotate around the output end of the reducer B. Simultaneously, under the radial limitation of the limiting groove 4012, the reciprocating linear movement mechanism 7 moves linearly back and forth under the drive of the swing arm B506. At the same time, the reducer B drives the two drive bevel gears B503 to rotate synchronously, driving the chain, which in turn drives the output gear 504 to rotate the input adjusting gear 602, causing the threaded shaft 601 to rotate. Based on the spiral meshing adjustment groove on the threaded shaft 601 connected to the meshing protrusion 6031, the chain is driven... The moving drive adjustment slider 603 is close to the reciprocating linear movement mechanism 7. With the setting of the idle slot, after the meshing protrusion 6031 is located at the end of the meshing adjustment slot, the cleaning drive assembly 5 continues to move in the same direction and can rotate in a circle in the idle slot. When the cleaning drive assembly 5 rotates relatively forward to input power, the two drive adjustment sliders 603 are relatively close. When the sliding seat 701 reciprocates linearly to the farthest ends on both sides, the extended contact shaft 7031 can contact the force-bearing protrusion 6032, so that the adjusting crank tooth 703 rotates. The rotation of the adjusting crank tooth 703 drives the swing tooth shaft 702 to drive the cleaning rod 8 to perform a flipping action and linear movement to clean the floating dust on the surface of the fixed display screen 2 and the movable display screen assembly 3. To clear snow and ice accumulation during rainy / snowy weather in S202: The servo motor 501 outputs power in the opposite direction, causing the reducer B to drive the bevel gear A502 to rotate. Power is also input to the swing arm A505 at the output end of the reducer B, causing the swing arm A505 to rotate around the output end of the reducer B. Simultaneously, under the radial limitation of the limiting groove 4012, the reciprocating linear movement mechanism 7 performs linear reciprocating movement driven by the swing arm B506. Simultaneously, based on the reducer B's drive, the two drive bevel gears B503 rotate synchronously, driving the chain... The output gear 504 synchronously drives the input adjustment gear 602 to rotate, causing the threaded shaft 601 to rotate. Based on the spiral meshing adjustment groove on the threaded shaft 601 connected to the meshing protrusion 6031, the adjustment slider 603 is driven to move away from the reciprocating linear movement mechanism 7. When the sliding seat 701 reciprocates linearly to the farthest ends on both sides, the extended contact shaft 7031 cannot contact the force-bearing protrusion 6032, maintaining a single linear reciprocating motion, and performing heat melting and cleaning of the snow and ice accumulation in the gap between the fixed display screen 2 and the movable display screen assembly 3 after folding.
