DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0054] Please refer to Figures 1-14 The technical solutions of the components and the operating principles in the present application will be described below in combination with the following embodiments, and the intelligent safety monitoring equipment and the safety guarantee operation scheme under fault are provided.

[0055] An intelligent underground overhead passenger device comprises upper cableway assemblies and lower cableway assemblies arranged side by side in an underground roadway. Each of the upper cableway assemblies and the lower cableway assemblies comprises winches 11 arranged at both ends of the roadway and steel wire ropes 12. Each of the winches 11 is assembled in a horizontal posture, and the steel wire ropes 12 are connected end to end and wound on the winches 11 at both ends of the roadway.

[0056] The device further comprises two sets of assembly supports 2 fixed to the wellhead and the underground. The winches 11 at the same end of the two sets of cableway assemblies are rotatably installed on the assembly supports 2 on the corresponding side and arranged on the same vertical axis. The steel wire ropes 12 in the two sets of cableway assemblies are arranged in parallel.

[0057] The power source and the transmission assembly are assembled on the two sets of assembling supports 2, the power source is in power connection with the transmission assembly, the transmission assembly is arranged on the axis of the winch 11, and the transmission assembly is in linkage with the winches 11 arranged on the same axis in the two sets of cableway assemblies.

[0058] The hanger 5 for traveling on the upper cableway assembly and the lower cableway assembly and the monkey car 6 connected to the bottom of the hanger 5 are further included, the hanger 5 is assembled with two sets of cable clamping assemblies 7, and the two sets of cable clamping assemblies 7 are respectively used for connecting the steel wire ropes 12 in the two sets of cableway assemblies.

[0059] The winches 11 assembled at the two ends of the roadway are arranged in a tilt manner in the roadway for entering and exiting the mine, and therefore, there is a height difference between the winches 11, in order to ensure that the steel wire ropes 12 are stably assembled on the winches 11 at different heights, avoid the steel wire ropes 12 from falling off the winches 11, and ensure the stability and safety of personnel transportation, guide wheels and supporting wheels in consistent contact with the steel wire ropes 12 are further assembled in the roadway, the guide wheels are mostly arranged at the positions of the two ends of the roadway, so that the steel wire ropes 12 are arranged in a tilt manner and are consistent with the tilt angle of the roadway, and the personnel are stably conveyed in the roadway without collision with the roadway, the supporting wheels are uniformly assembled in the roadway and arranged below the steel wire ropes 12, so as to avoid the steel wire ropes 12 from excessively sagging due to the self-weight or the personnel transportation process, and improve the safety of personnel transportation.

[0060] The power output by the power source is stably rotated to the winches 11 arranged on the same axis in the upper and lower cableway assemblies through the transmission assembly, the structural characteristics of the transmission assembly determine that the two sets of winches 11 arranged on the same axis can be independently operated through the transmission assembly when the power source is reversely rotated, and the upper cableway assembly and the lower cableway assembly can be maintained in the same direction, wherein the lower cableway assembly is a conventional conveying part for personnel conveying, and the upper cableway assembly is a safety redundant matching part, when the steel wire ropes 12 in the lower cableway assembly fall off or break, the hanger 5 and the matching cable clamping assembly 7 can be fixedly combined with the steel wire ropes 12 in the upper cableway assembly, the monkey car 6 and the personnel thereon are stably conveyed by the upper cableway assembly, and the safety accident caused by the falling of the conveying personnel is avoided.

[0061] In order to ensure the safety of the equipment operation, after the lower cableway assembly fails, the personnel being conveyed is conveyed by the upper cableway assembly, and then the whole equipment is stopped, and after the lower cableway assembly is maintained to be normal, the equipment is put into use again, so that the safety redundancy of the equipment exists at any time.

[0062] When the steel wire rope 12 of the lower cableway assembly is off or broken, the upper cable grip sinks under the gravity and is tightly gripped with the steel wire rope 12 of the upper cableway assembly to achieve fixed combination, so as to avoid the personnel from falling off the device, and then the power source is controlled to reverse operation and drive the winch 11 of the upper cableway assembly to maintain slow operation in the same direction with the lower cableway assembly to safely transfer the personnel being transported to the station.

[0063] When the steel wire rope 12 of the lower cableway assembly is off or broken, the upper cable grip sinks under the gravity and is tightly gripped with the steel wire rope 12 of the upper cableway assembly to achieve fixed combination, so as to avoid the personnel from falling off the device, and then the power source is controlled to reverse operation and drive the winch 11 of the upper cableway assembly to maintain slow operation in the same direction with the lower cableway assembly to safely transfer the personnel being transported to the station.

[0064] The power sources arranged at both ends of the tunnel adopt different power supply systems, or directly adopt different types of energy consumption equipment. One set of power sources is used as a conventional power source, and the other set of power sources acts as a power redundancy. When the power source acting as a conventional power source fails or is powered off, the power source acting as a power redundancy operates to ensure stable operation of the entire device.

[0065] Embodiment 1

[0066] To avoid the winch 11 from affecting the safety of personnel transportation due to too fast operation speed, and to avoid the winch 11 from overspeeding due to power source failure, the following technical solutions are provided to ensure rapid braking of the upper cableway assembly or the lower cableway assembly due to failure problems.

[0067] The shaft center of each set of winches 11 is fixedly connected with a brake disc, and the assembly support 2 is further assembled with a brake 112 arranged around each brake disc. A plurality of sets of brakes 112 are arranged in a ring array around each set of brake discs, and each set of brakes 112 is used to apply braking resistance to the corresponding brake disc.

[0068] The brake 112 adopts a caliper structure. When the brake 112 is triggered, the upper and lower caliper structures approach each other to clamp the brake disc in the middle to apply braking resistance, so as to ensure that the brake disc and the connected winch 11 are slowed down or braked, and the safety of the entire device is ensured. Since a plurality of sets of brakes 112 are arranged on the brake disc, the synchronous action of each brake 112 can ensure the balance of each winch 11 during braking.

[0069] The outer edge of the brake disc is provided with an annular heat dissipation cavity extending to the inner side of the brake disc. When the brake 112 acts on the brake disc, the friction generated will cause the temperature of the brake disc to rise, and the annular heat dissipation cavity helps to increase the contact area of the brake disc with cold air, facilitating the rapid cooling of the brake disc, and ensuring the stability and safety of the winch 11.

[0070] In order to improve the running stability of the steel wire rope 12 in the two groups of cableway assemblies, realize real-time quality monitoring of the steel wire rope 12, and perform maintenance or replacement of the steel wire rope 12 in advance, and to facilitate monitoring of the rotating speed of the winch 11 to avoid over-speed running of the steel wire rope 12, and to improve the safety of equipment operation, the following technical solutions are provided.

[0071] The connecting bracket 21 is fixed on the assembly bracket 2, and the mounting frame 22 is fixedly connected to the end of the connecting bracket 21. A plurality of uniformly arranged optical detection probes 221 are fixedly installed on the mounting frame 22. The steel wire rope 12 passes through the mounting frame 22 and is arranged towards the steel wire rope 12.

[0072] The mounting bracket 23 is fixed on the assembly bracket 2, and the photoelectric emitter 231 and the photoelectric receiver 232 are fixedly connected to the mounting bracket 23 in a vertically opposite manner. A plurality of light path through holes are uniformly provided on the brake disc.

[0073] The connecting bracket 21 can ensure that the mounting frame 22 and the optical detection probes 221 mounted on the mounting frame 22 are stably installed on the periphery of the steel wire rope 12. The optical detection probes 221 arranged in a ring array can optically detect each part of the passing steel wire rope 12 and determine whether the steel wire rope 12 has cracks or damage. Problems can be found in time to prevent accidents, and the steel wire rope 12 with safety risks can be replaced or maintained in time.

[0074] The steel wire rope 12 can be effectively detected by the optical detection probes 221 at each length position under the action of the winch 11.

[0075] The mounting bracket 23 can ensure that the photoelectric emitter 231 and the photoelectric receiver 232 are stably installed. The photoelectric emitter emits a photoelectric signal which is received and recorded by the photoelectric receiver 232. When the light path through holes uniformly arranged on the winch 11 pass through the mounting bracket 23, the photoelectric signal emitted by the photoelectric emitter 231 can pass through the light path through hole and be received by the photoelectric receiver 232. The time interval of the photoelectric signals received by the adjacent two groups of photoelectric receivers 232 can accurately calculate the rotating speed of the winch 11.

[0076] The triggering adjustment of the brake 112 is associated with the rotating speed of the winch 11. The calculated rotating speed of the winch 11 is used as a judgment condition to control the operation of the brake 112.

[0077] Embodiment 2

[0078] In order to ensure that the winches 11 in the two cableway assemblies are stably installed on the assembly support 2, and to ensure that the power source and the transmission assembly are stably installed on the assembly support 2, and further to ensure that the two cableway assemblies are stably operated, the following technical solutions are provided.

[0079] The assembly support 2 is horizontally fixed with an upper layer of pads 241, a middle layer of pads 242, a lower layer of pads 243, and a mounting bottom plate 244 arranged in sequence from top to bottom. The winches 11 and the matched brake discs in the upper cableway assembly are rotatably installed between the upper layer of pads 241 and the middle layer of pads 242. The winches 11 and the matched brake discs in the lower cableway assembly are rotatably installed between the middle layer of pads 242 and the lower layer of pads 243. The brake 112 and the mounting support 23 are fixedly installed on the middle layer of pads 242. The power source is fixedly installed on the mounting bottom plate 244. The transmission assembly is arranged through the upper layer of pads 241, the middle layer of pads 242, and the lower layer of pads 243.

[0080] The arrangement of the upper layer of pads 241, the middle layer of pads 242, and the lower layer of pads 243 can ensure that the winches 11 and the matched brake discs in the two cableway assemblies are stably installed in a relative rotating posture. In order to ensure that the brake 112, the photoelectric emitter 231, and the photoelectric receiver 232 installed on the two sides of the middle layer of pads 242 can effectively brake the winches 11 and accurately detect the rotational speed thereof, the brake discs matched in the upper cableway assembly are arranged below the corresponding winches 11, and the brake discs matched in the lower cableway assembly are arranged above the corresponding winches 11, i.e., the two brake discs are arranged on the two sides of the middle layer of pads 242, thereby ensuring that the brake 112, the photoelectric emitter 231, and the photoelectric receiver 232 can brake and measure the speed of the brake discs.

[0081] Circular guide grooves 245 are further arranged on the upper layer of pads 241, the middle layer of pads 242, and the lower layer of pads 243, so as to ensure that the winches 11 and the brake discs are stably installed in the circular guide grooves 245 in a relative rotating posture.

[0082] Embodiment 3

[0083] In order to ensure that the transmission assembly can drive the winches 11 in the two cableway assemblies to independently operate, and to ensure that the two winches 11 maintain the same operation, thereby meeting the safety of the underground passenger device operation, the following technical solutions are provided.

[0084] The assembly cavity 13 is provided at the center of the winch 11 and the matched brake disc, the transmission assembly comprises a transmission shaft 41, a mounting sleeve 42, a reversing assembly 43, an upper layer ratchet assembly 44 and a lower layer ratchet assembly 45, the mounting sleeve 42 is fixedly installed on the upper layer pad plate 241 and arranged in the assembly cavity 13 of the upper layer cableway assembly, the transmission shaft 41 is rotatably installed on the mounting sleeve 42 and the lower layer pad plate 243 and arranged at the center of the assembly cavity 13, and the transmission shaft 41 is power-connected with the power source, the upper layer ratchet assembly 44 and the lower layer ratchet assembly 45 are reversely arranged and linked with the transmission shaft 41, the upper layer ratchet assembly 44 and the reversing assembly 43 are assembled on the mounting sleeve 42, the reversing assembly 43 is linked with the upper layer ratchet assembly 44 and the assembly cavity 13 of the upper layer cableway assembly, and the lower layer ratchet assembly 45 is linked with the assembly cavity 13 of the lower layer cableway assembly.

[0085] The assembly cavity 13 can ensure the stable assembly of the transmission assembly in the winch 11 and the brake disc, and the winch 11 in the two cableway assemblies can be stably driven to rotate by the transmission shaft 41.

[0086] When the transmission shaft 41 rotates forward, the lower layer ratchet assembly 45 is in the meshing state and can stably transmit power, so that the winch 11 in the lower layer cableway assembly is stably driven to rotate forward and the steel wire rope 12 above the winch 11 is driven to run, and the upper layer ratchet assembly 44 is in the non-meshing state and cannot stably transmit power, so that the upper layer cableway is in the static state.

[0087] When the transmission shaft 41 reversely rotates, the lower layer ratchet assembly 45 is in the non-meshing state and cannot transmit power, so that the winch 11 in the lower layer cableway assembly is in the static state, and the upper layer ratchet assembly 44 is in the meshing state and can receive the power of the transmission shaft 41 and maintain reverse rotation, so that the winch 11 in the upper layer cableway assembly is stably driven to rotate forward by the reversing assembly 43, and the corresponding steel wire rope 12 is stably driven to run.

[0088] The mounting sleeve 42 can ensure that the upper layer ratchet assembly 44 and the reversing assembly 43 are stably installed in the assembly cavity 13 of the upper layer cableway assembly and linked with each other, and the transmission shaft 41 can be stably rotated.

[0089] In order to ensure that the lower layer ratchet assembly 45 can receive the power of the forward rotation of the transmission shaft 41 and drive the winch 11 in the lower layer cableway assembly to stably rotate, the following technical solutions are provided.

[0090] The lower ratchet assembly 45 comprises a lower mounting disc 451, a lower pawl 452, a lower ratchet disc 453, the lower mounting disc 451 is fixed on the transmission shaft 41, the lower pawl 452 comprises a plurality of groups which are rotatably mounted on the lower mounting disc 451 and are uniformly distributed, and a lower spring sheet 454 is assembled between the lower pawl 452 and the transmission shaft 41, the lower ratchet disc 453 is arranged at the periphery of the transmission shaft 41 and is in engagement with the lower pawl 452, and the lower ratchet disc 453 is fixed in the assembly cavity 13 of the lower cableway assembly.

[0091] When the transmission shaft 41 is driven to rotate in the forward direction, the lower mounting disc 451 and the lower pawl 452 can be driven to rotate synchronously, and the lower pawl 452 is pushed into the ratchet teeth at the inner edge of the lower ratchet disc 453 by the lower spring sheet 454, so that the lower ratchet disc 453 and the capstan 11 in the lower cableway assembly are stably driven to rotate by the rotating lower pawl 452.

[0092] When the transmission shaft 41 is reversely rotated, the lower pawl 452 rotates towards the side of the teeth, and the rotating lower pawl 452 cannot drive the lower ratchet disc 453 and the capstan 11 in the lower cableway assembly to rotate, so that the lower cableway assembly remains in a stationary state.

[0093] In order to ensure that the upper ratchet assembly 44 can receive the power of the reverse rotation of the transmission shaft 41 and drive the capstan 11 in the upper cableway assembly to stably rotate through the reversing assembly 43, the following technical solutions are provided.

[0094] The upper ratchet assembly 44 comprises an upper mounting disc 441, an upper pawl 442, and an upper ratchet disc 443, the upper mounting disc 441 is fixed on the transmission shaft 41, the upper pawl 442 comprises a plurality of groups which are rotatably mounted on the upper mounting disc 441 and are uniformly distributed, and an upper spring sheet is assembled between the upper pawl 442 and the transmission shaft 41, the upper ratchet disc 443 is arranged at the periphery of the transmission shaft 41 and is in engagement with the upper pawl 442, and the upper ratchet disc 443 is rotatably mounted on the mounting sleeve 42.

[0095] The reversing assembly 43 comprises a sun gear 431, a planet gear 432, and an inner ring gear 433, the sun gear 431 is fixed to the periphery of the upper ratchet disc 443, the planet gear 432 comprises a plurality of groups which are rotatably mounted on the mounting sleeve 42 and are arranged at the periphery of the sun gear 431 and are in engagement with the sun gear 431, and the inner ring gear 433 is fixed in the assembly cavity 13 of the upper cableway assembly and is arranged at the periphery of the planet gear 432 and is in engagement with the planet gear 432.

[0096] When the transmission shaft 41 is reversely rotated by the power source, the upper installation disc 441 and the upper pawl 442 thereon can be synchronously rotated, and the lower pawl 452 is pushed into the ratchet teeth on the inner edge of the lower ratchet disc 453 due to the action of the upper spring sheet. The upper pawl 442 in rotation drives the upper ratchet disc 443 and the sun gear 431 fixed to the upper ratchet disc 443 to stably rotate reversely on the installation sleeve 42, and further drives the planetary gear 432, the inner tooth ring 433 and the winch 11 of the upper cableway assembly to stably rotate forward. Due to the combination of the sun gear 431, the planetary gear 432 and the inner tooth ring 433, the winch 11 of the upper cableway assembly can be speed-reduced to ensure the safety and reliability of the upper cableway assembly as a safety redundant operation.

[0097] When the transmission shaft 41 is reversely rotated by the power source, the upper installation disc 441 and the upper pawl 442 thereon can be synchronously rotated, and the lower pawl 452 is pushed into the ratchet teeth on the inner edge of the lower ratchet disc 453 due to the action of the upper spring sheet. The upper pawl 442 in rotation drives the upper ratchet disc 443 and the sun gear 431 fixed to the upper ratchet disc 443 to stably rotate reversely on the installation sleeve 42, and further drives the planetary gear 432, the inner tooth ring 433 and the winch 11 of the upper cableway assembly to stably rotate forward. Due to the combination of the sun gear 431, the planetary gear 432 and the inner tooth ring 433, the winch 11 of the upper cableway assembly can be speed-reduced to ensure the safety and reliability of the upper cableway assembly as a safety redundant operation.

[0098] To ensure that the power source can stably drive the transmission shaft 41 to rotate, and at the same time, a large enough torque can be input to the transmission shaft 41 to ensure that the upper cableway assembly and the lower cableway assembly can stably and slowly rotate, the following technical solutions are provided.

[0099] The power source is a driving motor 31, which is connected with a planetary reducer 32, and a driving bevel gear 321 is fixed to the output shaft of the planetary reducer 32. The bottom of the transmission shaft 41 is fixed with a transmission bevel gear 411, and the transmission bevel gear 411 is in meshing with the driving bevel gear 321.

[0100] When the driving motor 31 rotates, the output torque is increased by the speed reduction and torque increase of the planetary reducer 32, and then the transmission shaft 41 is stably rotated by the combination of the driving bevel gear 321 and the transmission bevel gear 411, so as to realize the stable operation of the winch 11 at a low speed and a large torque.

[0101] The driving motor 31 connected to the support bracket 2 at both ends of the tunnel is connected with different power supply systems, so that the stable operation of the underground passenger device can be ensured even if one set of power supply system fails.

[0102] As an optimized alternative, one set of driving motor 31 and planetary reducer 32 can be replaced by a diesel engine and a matching gearbox respectively. The diesel engine serving as a power source is usually arranged outside the wellhead to ensure the safety of mine operation. Since the diesel engine can generate power by burning diesel oil, the underground passenger device can still operate even if the power system fails.

[0103] Embodiment 4

[0104] In order to ensure that the hanger 5 is stably combined with the steel wire rope 12 on the two groups of cableway assemblies through the holding rope assembly 7, and to facilitate the regulation of the tightness of the holding rope assembly 7, the following technical solutions are provided.

[0105] The hanger 5 is fixedly connected with two groups of arc-shaped backing plates 51, and the two groups of arc-shaped backing plates 51 are each provided with a holding rope assembly 7. The holding rope assembly 7 comprises a pressing seat 71, a pin rod 72, a reset spring 73 and a clamping plate 74. The pin rod 72 is fixedly connected to the top of the pressing seat 71 and is slidingly inserted into the arc-shaped backing plate 51. The reset spring 73 is wound around the outer periphery of the pin rod 72 and the two ends thereof are respectively in abutment with the pressing seat 71 and the arc-shaped backing plate 51. The clamping plate 74 comprises two groups of clamping plates symmetrically arranged on both sides of the pressing seat 71. The two groups of clamping plates 74 are each fixedly connected with a support rod 741 arranged in a cross shape. The middle sections of the two groups of support rods 741 are hingedly connected. The pressing seat 71 is hingedly connected with two groups of connecting rods 711. The other ends of the two groups of connecting rods 711 are respectively hingedly connected with the top ends of the two groups of support rods 741.

[0106] The arrangement of the arc-shaped backing plate 51 can ensure that the pin rod 72 connected to the pressing seat 71 in the holding rope assembly 7 is stably installed thereon. The reset spring 73 can drive the pin rod 72 and the pressing seat 71 to move downward in a natural state, thereby driving the outer periphery of the two groups of clamping plates 74 through the connecting rods 711 and the support rods 741, and canceling the clamping effect of the clamping plates 74 on the steel wire rope 12.

[0107] When the holding rope assembly 7 is used in cooperation with the steel wire rope 12, the pressing seat 71 is in abutment with the top of the steel wire rope 12 under the action of gravity, and overcomes the resistance of the reset spring 73 to make the pressing seat 71 move in the direction close to the arc-shaped backing plate 51, thereby driving the two groups of clamping plates 74 to move close to each other through the connecting rods 711 and the support rods 741, so as to clamp the steel wire rope 12 on both sides, thereby realizing the stable combination of the holding rope assembly 7 and the steel wire rope 12.

[0108] In order to ensure that the monkey car 6 can be stably installed on the hanger 5, and at the same time ensure that the passengers are stably conveyed in the inclined tunnel, the following technical solutions are provided.

[0109] The bottom of the hanger 5 is slidingly inserted with a pin shaft 52, and the outer periphery of the pin shaft 52 is provided with a support spring 53 in abutment with the bottom of the hanger 5 and the end of the pin shaft 52. The top end of the monkey car 6 is fixedly connected with a hinged seat 61, and the hinged seat 61 is rotatably installed at the bottom of the pin shaft 52.

[0110] The arrangement of the support spring 53 can support the pin shaft 52 upward, so as to facilitate the hanger 5 and the monkey car 6 to be stably installed when passing through the support wheels arranged in the tunnel. The arrangement of the hinged seat 61 at the top of the monkey car 6 can cope with the situation that the passengers always present a drooping posture under the action of gravity when traveling in the inclined tunnel, thereby ensuring the stability and safety of the passenger conveying.
