Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and in particular to a device and method for preventing a rope from falling off an overhead passenger device. Background Art

[0002] Overhead passenger devices are important personnel or material transportation equipment in coal mines and other enterprises. During operation, they are mainly driven by traction wires. Therefore, during operation, they are very susceptible to external impact vibration, steel wire wear, wire sheave damage and other factors, causing the traction wires to fall off, seriously affecting the safety of the overhead passenger device. At the same time, they also cause serious wear and tear on the overhead passenger device, traction drive steel wires and rope sheaves, seriously shortening the service life of the equipment and increasing the equipment operation and maintenance costs.

[0003] According to a Chinese patent application number 202210490812.3, a synchronous wheeled anti-rope-drop protection device for an overhead passenger device is disclosed, which effectively meets the needs of various tunnel structures and the supporting operation of the overhead passenger device. At the same time, it can effectively realize effective load-bearing protection of the traction steel strand during operation, thereby greatly improving the reliability and safety of the operation of the overhead passenger device. Nevertheless, the rope gripper will push the guide roller upward during the movement, and the cable still has the possibility of falling off during the upward floating of the guide roller. For this reason, we propose an anti-rope-drop protection device and method for an overhead passenger device to solve the above-mentioned technical problems. Summary of the Invention

[0024] As a preferred solution of the present invention, the loose holding portion includes:

[0025] An L-shaped lifting plate is fixedly mounted on the upper outer walls of the two telescopic rods;

[0026] The positioning shaft is fixedly installed on the side of the L-shaped lifting plate;

[0027] A rubber wheel, rotatably mounted on the periphery of the positioning shaft;

[0028] A fixed plate, fixedly mounted on the tower of the overhead passenger device;

[0029] The wheel diameter guide rail is fixedly mounted on a side of the fixed plate close to the overhead passenger cable, and its height and position are adapted to the rubber wheel. The wheel diameter guide rail is arched.

[0030] As a preferred solution of the present invention, a bracket is fixedly installed on one side of the loose holding portion close to the wheel guide rail, the bracket is located at the bottom of the overhead passenger cable, and a rope hoop is fixedly installed on the top of the bracket, the rope hoop is located on the periphery of the overhead passenger cable.

[0031] As a preferred solution of the present invention, the rope holding portion further includes:

[0032] A groove is provided on a side surface of the mounting plate close to the side plate;

[0033] A pressure wheel, rotatably mounted inside the groove;

[0034] The wedge-shaped guide rail is fixedly mounted on a side surface of the side plate close to the mounting plate, and the surface of the wedge-shaped guide rail is in rolling connection with the surface of the pressure wheel.

[0035] As a preferred solution of the present invention, two wheel axles are fixedly installed on one side of the fixed plate close to the bracket, and the outer periphery of the two wheel axles is rotatably installed with rope support wheels through bearings. The bracket is located between the two brackets, and the cable of the overhead passenger device is installed on the top of the two rope support wheels.

[0036] As a preferred solution of the present invention, a pressure strip is fixedly installed on one side of the fixed plate close to the wheel guide rail, and the pressure strip is located at the bottom of the wheel guide rail, wherein a sliding strip is fixedly installed on the outer side of the side plate close to the rubber wheel side, and the height difference between the top of the sliding strip and the bottom of the pressure strip is 2 mm.

[0037] As a preferred solution of the present invention, a connecting angle plate is fixedly installed on the outer side surface of one of the side panels away from the rubber wheel, and the connecting angle plate is used to fix the monkey car frame of the overhead passenger device.

[0038] A method for preventing a rope from falling off of an overhead passenger device includes the following steps:

[0039] S1. Pass the cable through the inside of the rope hoop and securely connect the top of the monkey bike frame to the side of the connecting angle plate with bolts.

[0040] S2, the overhead cable carries the gripping part and the loose gripping part to move, further driving the monkey car frame and the miners to move;

[0041] During the movement, one of the rubber wheels first rolls to the top of the wheel guide rail, lifting the L-shaped lifting plate upward, which in turn drives the telescopic rod upward, causing the two cable clamps to open and pass around the outside of the rope clamp, while the other cable clamp still clamps and tightens the cable.

[0042] S4. When one of the rubber wheels rolls along the top of the wheel guide to the other end, the two rope clamps in that section merge and clamp the cable again, while the other rubber wheel immediately rolls to the top of the wheel guide, causing the two rope clamps associated with it to open and continue to pass around the outer periphery of the rope clamp.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. In the present invention, the cable passes through the interior of the rope clamp and will not fall off from the wheel groove of the rope support pulley. At the same time, when the two rope holding parts alternately pass through the rope clamp, one rope holding part is always guaranteed to be in a state of holding the cable, so as to prevent the device from falling off the cable. This greatly improves the safety of miners' carrying operations, reduces the potential safety hazards of miners' production operations, and protects the personal safety and property safety of mining workers.

[0045] 2. In the present invention, when the cable-carrying side plate moves to the side of the fixed plate, the slide bar just moves with the side plate to the bottom of the pressure bar, and the two are interlocked with each other. As the side plate continues to move, the slide bar slides along the bottom of the pressure bar, so that in the process of the rubber wheel being lifted upward by the wheel diameter guide rail, the entire device will not shift upward due to the downward limiting effect of the pressure bar on the slide bar, thereby ensuring the stability of the device transportation.

DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0056] See also Figure 1 - Figure 8 The technical solution provided by the present invention specifically includes the following embodiments:

[0057] A rope-fall prevention protection device for an overhead passenger device includes side panels 100, a top panel 200, a rope-holding portion 300, and a loosening portion 400. There are two side panels 100, and the top panel 200 is symmetrically distributed and fixedly mounted on the top ends of the two side panels 100 in the middle of the two side panels 100. The rope-holding portion 300 is movably arranged at the bottom of the top panel 200 and is located between the two side panels 100. There are two rope-holding portions 300, and the loosening portion 400 is fixedly arranged on the top of the side panels 100.

[0058] For further details, please refer to Figure 6 、 Figure 7 As shown:

[0059] The cable holding portion 300 includes a telescopic rod 301, a sheet metal bracket 302, a spring 303, a No. 1 axle pin 305, a connecting rod 306, a No. 2 axle pin 307, a metal slot 308, a mounting plate 309, a cable holding clamp 3010, an arc groove 3011, a groove 3015, a pressure wheel 3016 and a wedge-shaped guide rail 3017. The telescopic rod 301 is symmetrically distributed and slidably installed on the inside of the top plate 200 with the central axis of the top plate 200. The sheet metal bracket 302 is fixedly installed at the bottom of the two telescopic rods 301. The spring 303 is sleeved on the periphery of the telescopic rod 301 and fixedly installed between the bottom of the top plate 200 and the top of the sheet metal bracket 302. The No. 1 axle pin 305 is fixedly installed on the inside of the sheet metal bracket 302. There are four of them and they are arranged in sequence. The connecting rod 306 is rotatably installed on the periphery of the No. 1 axle pin 305. The No. 2 axle pin 307 is fixedly installed on the At the end of the connecting rod 306 away from the No. 1 axle pin 305, there are two metal slots 308, which are symmetrically distributed about the central axis of the sheet metal bracket 302. The metal slot 308 is rotatably connected to the two connecting rods 306 located on one side of the central axis of the sheet metal bracket 302 through bearings. The mounting plate 309 is fixedly mounted on the bottom of the metal slot 308, and the rope clamp 3010 is fixedly mounted on the bottom of the mounting plate 309. The arc groove 3011 is opened at the bottom of the rope clamp 3010, and its specifications are adapted to the thickness specifications of the overhead passenger cable. The groove 3015 is opened on a side of the mounting plate 309 close to the side plate 100, and the pressure wheel 3016 is rotatably mounted inside the groove 3015. The wedge guide rail 3017 is fixedly mounted on a side of the side plate 100 close to the mounting plate 309, and the surface of the wedge guide rail 3017 is rollingly connected to the surface of the pressure wheel 3016.

[0060] Specifically, the sheet metal bracket 302 is pushed downward by the elastic force of the spring 303, and further driven to move downward by the connection of the No. 1 axle pin 305, the connecting rod 306, and the No. 2 axle pin 307. The metal slot 308, the mounting plate 309, and the rope clamp 3010 move downward, and the mounting plate 309 moves downward, driving the pressure wheel 3016 to roll downward along the inclined surface of the wedge-shaped guide rail 3017. Therefore, during the downward movement of the two rope clamps 3010, they gradually close together and clamp around the outer periphery of the cable, thereby fixing the device on the cable of the overhead passenger device, realizing the transportation operation of the miners.

[0061] For further details, please refer to Figure 3 、 Figure 4 、 Figure 6 as well as Figure 7 As shown:

[0062] The rope holding portion 300 further includes a first fixing ear 3012, a second fixing ear 3013, and a tension spring 3014. The first fixing ear 3012 is fixedly mounted on a side of the outermost first fixing ear 3012 close to the side plate 100. The second fixing ear 3013 is fixedly mounted on a side of the side plate 100 close to the first fixing ear 3012. The tension spring 3014 is fixedly mounted between the second fixing ear 3013 and the first fixing ear 3012.

[0063] The loose holding portion 400 includes an L-shaped lifting plate 401, a positioning shaft 402, a rubber wheel 403, a fixing plate 404 and a wheel diameter guide rail 405. The L-shaped lifting plate 401 is fixedly mounted on the upper portion of the outer wall of the two telescopic rods 301, the positioning shaft 402 is fixedly mounted on the side of the L-shaped lifting plate 401, the rubber wheel 403 is rotatably mounted on the periphery of the positioning shaft 402, the fixing plate 404 is fixedly mounted on the tower of the overhead passenger device, the wheel diameter guide rail 405 is fixedly mounted on a side of the fixing plate 404 close to the overhead passenger cable, and the height and position are adapted to the rubber wheel 403. The wheel diameter guide rail 405 is arched. The loose holding portion 400 is fixedly mounted on a side close to the wheel diameter guide rail 405. A bracket 500 is installed, and the bracket 500 is located at the bottom of the overhead passenger cable, and a rope hoop 501 is fixedly installed on the top of the bracket 500, and the rope hoop 501 is located on the periphery of the overhead passenger cable. Two wheel axles 800 are fixedly installed on one side of the fixed plate 404 close to the bracket 500, and the peripheries of the two wheel axles 800 are rotatably mounted with rope supporting wheels 900 through bearings. The bracket 500 is located between the two brackets 500, and the cable of the overhead passenger device is installed on the top of the two rope supporting wheels 900, and a connecting angle plate 1000 is fixedly installed on the outer side of a side plate 100 away from the rubber wheel 403. The connecting angle plate 1000 is used to fix the monkey car frame of the overhead passenger device.

[0064] Specifically, when the cable clamping block 3010 is closed toward the middle, the connecting rod 306 will drive the No. 1 fixed ear 3012 to move, causing the tension spring 3014 to stretch and store force. It should be noted here that the elastic force value of the tension spring 3014 is much smaller than the elastic force value of the spring 303. As the cable is driven by the overhead passenger device, it rotates circuitously, thereby driving the cable holding part 300 to move together. When the cable holding part 300 moves with the cable to a position close to the fixed plate 404, first a rubber wheel 403 contacts the inclined surface of one side of the top of the wheel guide rail 405, and rolls upward along the inclined surface of the wheel guide rail 405, further lifting the L-shaped lifting plate 401 together with the two telescopic rods 301 fixedly connected to the L-shaped lifting plate 401. The rod 301 then drives the sheet metal bracket 302 to move upward together, causing the two springs 303 to be compressed and elastically deformed. The upward movement of the sheet metal bracket 302 further drives the metal slot 308 and the mounting plate 309 to move upward through the connection of the No. 1 axle pin 305, the connecting rod 306 and the No. 2 axle pin 307, so that the pressure wheel 3016 rolls upward along the inner inclined surface of the wedge-shaped guide rail 3017. The rebound force of the tension spring 3014 in the stretched and stored state is released, pulling the connecting rod 306 to rotate along the No. 1 axle pin 305 toward the side plate 100, and further, under the connection of the connecting rod 306 and the No. 2 axle pin 307, drives the metal slot 308, the mounting plate 309 and the cable clamp 3010 toward the side plate 100. When the two opened rope clamping blocks 3010 completely pass over the rope hoop 501, the corresponding rubber wheel 403 just detaches from the other end of the wheel guide rail 405, and the rebound force of the spring 303 is released, which makes the plate 300 move in the opposite direction, thereby making the two rope clamping blocks 3010 open, and then the two arc-shaped grooves 3011 release the rope holding effect on the cable. Since the inner walls of the two rope clamping blocks 3010 are separated from the cable, a gap is generated between the inner wall of the rope clamping blocks 3010 and the outer surface of the cable. As a result, when the two arc-shaped grooves 3011 pass through the outer periphery of the rope hoop 501, they will not interfere with the rope hoop 501, and the two rope clamping blocks 3010 on the other rope holding part 300 still hold the cable tightly, ensuring that the device will not fall off the cable to avoid danger. When the two opened rope clamping blocks 3010 completely pass over the rope hoop 501, the corresponding rubber wheel 403 just detaches from the other end of the wheel guide rail 405, and the rebound force of the spring 303 is released, The metal bracket 302 pushes downward, and further drives the metal slot 308, the mounting plate 309 and the cable clamping block 3010 to move downward under the connection of the No. 1 shaft pin 305, the connecting rod 306 and the No. 2 shaft pin 307. The mounting plate 309 moves downward, driving the pressure wheel 3016 to roll downward along the inclined surface of the wedge-shaped guide rail 3017. Therefore, during the downward movement of the two cable clamping blocks 3010, they gradually close toward the middle and hold the outer periphery of the cable again. Subsequently, the other rubber wheel 403 just rolls to the top inclined surface position of the wheel diameter guide rail 405, and the above process is repeated, so that the device can achieve the anti-falling effect of the cable through the rope clamp 501. In the process of the two rope holding parts 300 alternately passing through the rope clamp 501,It is always ensured that one of the rope gripping parts 300 is in a state of gripping the cable to prevent the device from falling off the cable, which greatly improves the safety of miners' carrying operations and reduces the potential safety hazards of miners' production operations.

[0065] For further details, please refer to Figure 8 As shown:

[0066] A pressure strip 600 is fixedly installed on one side of the fixed plate 404 close to the wheel guide rail 405, and the pressure strip 600 is located at the bottom of the wheel guide rail 405. A sliding bar 700 is fixedly installed on the outer side of the side plate 100 close to the rubber wheel 403, and the height difference between the top of the sliding bar 700 and the bottom of the pressure strip 600 is 2 mm.

[0067] Specifically, when the cable-carrying side plate 100 moves to the side of the fixed plate 404, the slide bar 700 just moves with the side plate 100 to the bottom of the pressure bar 600, and the two are interlocked with each other. As the side plate 100 continues to move, the slide bar 700 slides along the bottom of the pressure bar 600, and a 2mm gap is set between the top of the slide bar 700 and the bottom of the pressure bar 600, which can ensure that the end of the slide bar 700 will not come into contact with the end of the pressure bar 600 during the process of approaching the pressure bar 600, so that the slide bar 700 can slide smoothly into the bottom of the pressure bar 600, so that when the rubber wheel 403 is lifted upward by the wheel guide rail 405, the entire device will not shift upward due to the downward limiting action of the pressure bar 600 on the slide bar 700, thereby ensuring the stability of the device transportation.

[0068] A method for preventing a rope from falling off of an overhead passenger device includes the following steps:

[0069] S1. Pass the cable through the inside of the rope hoop 501 and fix the top of the monkey bike frame to the side of the connecting angle plate 1000 with bolts;

[0070] S2, the overhead cable carries the gripping unit 300 and the loosening unit 400 to move, further driving the monkey car frame and the miners to move;

[0071] S3. During the movement process, one of the rubber wheels 403 first rolls to the top of the wheel guide rail 405, lifting the L-shaped lifting plate 401 upward, which in turn drives the telescopic rod 301 upward, causing the two cable clamps 3010 to open, thereby bypassing the outside of the rope clamp 501, while the other cable clamp 300 still clamps and tensions the cable;

[0072] S4. When one of the rubber wheels 403 rolls along the top of the wheel guide rail 405 to the other end, the two rope clamping blocks 3010 in that part merge to clamp the cable again, and the other rubber wheel 403 immediately rolls to the top of the wheel guide rail 405, causing the two rope clamping blocks 3010 associated with it to open and continue to pass around the outer periphery of the rope clamp 501.

[0073] When the anti-rope-drop protection device of the overhead passenger device of this solution is in operation, the fixing plate 404 is fixedly installed on the tower, and the two rope supporting wheels 900 are supported at the bottom of the cable to ensure that the cable is located in the wheel groove at the top of the rope supporting wheel 900 and passes through the interior of the rope clamp 501. Under the driving action of the overhead passenger device, the cable rotates in a circuitous manner, thereby driving the rope holding part 300 to move together. The monkey car frame is fixed to the bottom of the connecting angle plate 1000, so that the miners can be carried. Since the cable shuttles through the interior of the rope clamp 501, the cable will not fall off from the wheel groove of the rope supporting wheel 900 during the circuitous rotation process, thereby ensuring the stability and safety of the transportation.

[0074] When the cable holding part 300 moves with the cable to a position close to the fixed plate 404, first a rubber wheel 403 contacts the inclined surface of one side of the top of the wheel guide rail 405 and rolls upward along the inclined surface of the wheel guide rail 405, further lifting the L-shaped lifting plate 401 together with the two telescopic rods 301 fixedly connected to the L-shaped lifting plate 401. The two telescopic rods 301 then drive the sheet metal bracket 302 to move upward together, causing the two springs 303 to compress and produce elastic deformation. The sheet metal bracket 302 moves upward through the connection of the No. 1 shaft pin 305, the connecting rod 306 and the No. 2 shaft pin 307, further driving the metal slot 308 and the mounting plate 309 to move upward, so that the pressure wheel 301 6 rolls upward along the inner inclined surface of the wedge-shaped guide rail 3017, and the rebound force of the tension spring 3014 in the stretched and stored state is released, pulling the connecting rod 306 to rotate along the No. 1 axis pin 305 toward the side plate 100. Further, under the connection of the connecting rod 306 and the No. 2 axis pin 307, the metal slot plate 308, the mounting plate 309 and the cable clamping block 3010 are driven to move toward the side plate 100, thereby opening the two cable clamping blocks 3010, and then releasing the two arc grooves 3011 from holding the cable. As the inner walls of the two cable clamping blocks 3010 are separated from the cable, a gap is generated between the inner wall of the cable clamping block 3010 and the outer surface of the cable, thereby When the two opened rope clamps 3010 completely pass over the rope hoop 501, the corresponding rubber wheel 403 just detaches from the other end of the wheel guide rail 405, and the rebound force of the spring 303 is released, pushing the sheet metal bracket 302 downward, and further driving the metal slot 308, the mounting plate 309 and the rope clamp 3010 to move downward under the connection of the No. 1 axle pin 305, the connecting rod 306 and the No. 2 axle pin 307. The mounting plate 309 moves downward. The two rope clamps 3010 gradually move toward the center and clamp the outer periphery of the cable again. Subsequently, the other rubber wheel 403 just rolls to the top inclined surface of the wheel guide rail 405, and the above process is repeated. This allows the device to prevent the cable from falling off through the rope clamp 501. When the two rope clamps 300 alternately pass through the rope clamp 501, one of the rope clamps 300 is always in a state of clamping the cable to prevent the device from falling off from the cable, thereby greatly improving the safety of the miners' carrying operations and reducing the potential safety hazards of the miners' production operations.

[0075] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
