Description

In practice, a lot of preparatory work is often required, such as preparing a large amount of earth and stone materials for plugging in advance, and then using professional lifting equipment to throw the earth and stone materials for plugging into the breach of the dam. These preparatory works take a lot of time, and as time goes by, the breach of the dam will continue to grow, which will increase the difficulty of subsequent plugging work and lead to a decrease in plugging efficiency.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The self-propelled dam breach plugging material rapid throwing device described in the present invention drives the power wheel through the motor and transmission in the structural frame, thereby driving the crawler, supporting wheel and driven wheel to rotate. When the structural frame moves to a suitable position through the crawler, it stops, and the hydraulic cylinders in several brackets are started. The hydraulic cylinders drive the telescopic frame to move toward the ground, thereby propping up the crawler and the structural frame so that the crawler is no longer in contact with the ground. At this time, the material for plugging the breach is placed on the crawler, and the transmission of the crawler is used to quickly throw the plugging material into the breach of the dam. Through the designed structure, the conversion of the two modes is realized, so that the structural frame can quickly reach the designated position and transport the plugging material through the crawler, which saves equipment while improving the transportation efficiency, realizing rapid plugging operations, thereby shortening the time for preparing the lifting equipment in the early stage, and effectively preventing the expansion of the dam breach due to continuous scouring.

[0018] 2. The self-propelled dam breach plugging material rapid throwing device described in the present invention uses two electric push rods to move the fixed plate, the rotating plate and the buffer plate in a direction close to each other. As the plugging material begins to be thrown and falls onto the buffer plate, the buffer plate will slide and retract toward the rotating plate after being impacted, and squeeze the spring in the rotating plate, thereby playing a role in buffering and protecting the rotating plate and the crawler track, preventing the plugging material from falling directly onto the crawler track, causing the crawler track to be easily damaged after being impacted for a long time. As the plugging material continues to fall onto the buffer plate, affected by the weight of the plugging material, the rotating plate will rotate with the buffer plate in the direction of the fixed plate, thereby increasing the space between the two rotating plates, making it convenient for the plugging material to fall onto the crawler track through the two rotating plates, and allowing the crawler track to move with the plugging material to the breach of the dam for plugging operations.

[0019] 3. The self-propelled dam breach plugging material rapid throwing device described in the present invention plays the role of auxiliary support of the rotating plate by installing a fixed cylinder, a support rod and an elastic ball, so as to prevent the rotating plate from excessively rotating and hitting the fixed plate. At the same time, when the rotating plate rotates, it will move into the fixed cylinder with the support rod, and use the support rod to squeeze the gas in the elastic ball and the fixed cylinder. After the elastic ball is squeezed, the gas inside will enter the fixed cylinder through the shrinkage hole, and follow the gas in the fixed cylinder through the vent pipe into the hollow column. When the hollow column begins to inflate, it will push the internal sliding column and scraper and other parts to move away from the connecting plate, and use the scraper to scrape and clean the surface of the crawler, so as to scrape off the impurities adhering to the surface of the crawler and the impurities such as stones stuck in the gaps of the crawler, so as to reduce the impact of the subsequent plugging materials on the impurities on the surface of the crawler when they fall, resulting in the occurrence of impurities such as stones damaging the crawler after multiple impacts. When the plugging material leaves the rotating plate, the rotating plate is reset, and the scraper, auxiliary plate and other parts slide and reset. When the auxiliary plate is reset, it will clean the impurities at different positions on the crawler. The cone rods on the auxiliary plate are used to pre-crush the impurities on the track, and the impurities are taken out of the track surface under the drive of the subsequent auxiliary plate.

[0020] 4. The self-propelled dam breach plugging material rapid throwing device described in the present invention, by energizing the first electromagnet and the second electromagnet, allows the second electromagnet to move in the direction of the first electromagnet with the fan blades, connecting rod, sliding block and spring. The fan blades are affected by the liquid when moving and rotate continuously, thereby stirring the liquid in the storage box, so that the precipitated liquid is quickly stirred and mixed again, thereby giving full play to the effect. The electric push rod moves to the storage box with the fixed rod and the pressure plate through the fixed plate and squeezes. After the storage box is squeezed, the liquid inside will enter the liquid spray pipe through the liquid outlet pipe, and will be sprayed out through the liquid spray pipe and the guide nozzle, spraying the liquid on the track.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 9As shown, a self-propelled dam breach plugging material fast throwing device according to an embodiment of the present invention comprises a structural frame 1, a power wheel 2 and a driven wheel 3 are respectively installed at both ends of the structural frame 1, a motor for driving the power wheel 2 is installed in the structural frame 1, a plurality of rotating support wheels 5 are installed on the structural frame 1, and tracks 4 are installed on the surfaces of the power wheel 2, the driven wheel 3 and the support wheel 5. A plurality of brackets 6 are fixedly installed on both sides of the structural frame 1, and a telescopic frame 7 is connected to the inside of the bracket 6 through a hydraulic cylinder, and the telescopic frame 7 is slidably connected to the bracket 6.

[0041] When working, the motor and transmission in the structural frame 1 drive the power wheel 2 (this is the prior art, similar to the tank track 4, no more details are given here), which in turn drives the track 4, the supporting wheel 5 and the driven wheel 3 to rotate. It should be noted that at this time, the telescopic frame 7 in the bracket 6 is not in contact with the ground, and the track 4 is in direct contact with the ground. Through the movement of the track 4, the entire structural frame 1 moves, and thus moves to the breach of the dam.

[0042] When the structural frame 1 moves to a suitable position through the crawler 4, it stops and the hydraulic cylinders in the several brackets 6 are started. The hydraulic cylinders drive the telescopic frames 7 to move toward the ground, thereby propping up the crawler 4 and the structural frame 1, so that the crawler 4 is no longer in contact with the ground. At this time, the materials for plugging the breach are placed on the crawler 4, and the transmission of the crawler 4 is used to quickly put the plugging materials into the breach of the dam.

[0043] Through the structure of the above design, the conversion between the two modes is realized, so that the structural frame 1 can quickly reach the designated position and transport the blocking materials through the crawler 4, saving equipment while improving the transportation efficiency, realizing rapid blocking operations, thereby shortening the time for preliminary preparation of lifting equipment and effectively preventing the expansion of the dam breach due to continuous scouring.

[0044] The buffer mechanism 10 includes two bases 11 symmetrically arranged with the track 4 as the center axis. The bases 11 are attached to the structural frame 1 by screws. An electric push rod 12 is fixedly installed on the top of the base 11. An "L"-shaped fixed plate 13 is fixedly installed on the output end of the electric push rod 12. The side of the fixed plate 13 away from the electric push rod 12 is rotatably connected to an inclined rotating plate 14 through a torsion spring. The top of the rotating plate 14 is slidably connected to a buffer plate 15 through a spring. A slide groove 16 is provided on the base 11. A slider 17 is fixedly installed on the bottom of the fixed plate 13. The slider 17 slides in the slide groove 16. A support mechanism 20 is provided on the fixed plate 13. The support mechanism 20 includes a plurality of fixed cylinders 21 fixedly installed on the fixed plate 13. A support rod 22 is slidably connected in the fixed cylinder 21 through an elastic ball 23. One end of the support rod 22 is fixedly connected to the rotating plate 14. Both the fixed cylinder 21 and the support rod 22 are arc-shaped.

[0045] Specifically, a cleaning assembly 24 is provided on one side of the base 11. The cleaning assembly 24 includes a connecting plate 241 fixedly installed on one side of the base 11. A plurality of hollow columns 242 are fixedly installed on one side of the connecting plate 241. A sliding column 243 is sealingly and slidingly connected inside the hollow column 242. A scraper 244 is fixedly installed on one end of the sliding column 243 away from the hollow column 242. The support rod 22 and the fixed cylinder 21 are densely slidably connected. A shrinkage hole is provided on the surface of the elastic ball 23. A vent pipe 245 connected to the inside is fixedly installed on one side of the fixed cylinder 21. The end of the vent pipe 245 away from the fixed cylinder 21 is connected to the inside of the hollow column 242. An auxiliary assembly 25 is provided on one side of the scraper 244. The auxiliary assembly 25 includes an auxiliary plate 251 fixedly installed on one side of the scraper 244. A plurality of cone rods 252 are provided on one side of the auxiliary plate 251. The scraper 244 and the auxiliary plate 251 are both arc-shaped, and the bottom of the auxiliary plate 251 of the scraper 244 is fixedly installed with a rubber sheath 253. The scraper 244 and the auxiliary plate 251 are movably connected with a swing rod 254 through a torsion spring, and the bottom of the swing rod 254 is a funnel design.

[0046] During operation, after the structural frame 1 moves to a suitable position and before the blocking material is placed, the electric push rods 12 on the two bases 11 are started, and the two electric push rods 12 are used to move the fixed plate 13, the rotating plate 14 and the buffer plate 15 in a direction close to each other, so that the two rotating plates 14 are above the crawler 4. As the blocking material begins to be placed and falls on the buffer plate 15, the buffer plate 15 will slide and retract toward the rotating plate 14 after being impacted, and squeeze the spring in the rotating plate 14, thereby buffering and protecting the rotating plate 14 and the crawler 4, preventing the blocking material from falling directly onto the crawler 4, causing the crawler 4 to be easily damaged after being impacted for a long time. As the blocking materials continue to fall onto the buffer plate 15, affected by the weight of the blocking materials, the rotating plate 14 will rotate with the buffer plate 15 toward the fixed plate 13, thereby increasing the space between the two rotating plates 14, making it easier for the blocking materials to fall onto the crawler track 4 through the two rotating plates 14, allowing the crawler track 4 to move with the blocking materials to the breach of the dam for blocking operations.

[0047] The fixed cylinder 21, the support rod 22 and the elastic ball 23 are installed to assist in supporting the rotating plate 14, so as to prevent the rotating plate 14 from excessively rotating and hitting the fixed plate 13. At the same time, when the rotating plate 14 rotates, it will move into the fixed cylinder 21 with the support rod 22, and use the support rod 22 to squeeze the gas in the elastic ball 23 and the fixed cylinder 21. After the elastic ball 23 is squeezed, the gas inside will enter the fixed cylinder 21 through the shrinkage hole, and follow the gas in the fixed cylinder 21 through the vent pipe 245 to enter the hollow column 242. When the hollow column 242 begins to be inflated, it will push the internal sliding column 243 and the scraper 244 and other parts to move away from the connecting plate 241, and use the scraper 244 to scrape and clean the surface of the crawler 4, so as to scrape off the impurities adhering to the surface of the crawler 4 and the impurities such as stones stuck in the gaps of the crawler 4, so as to reduce the impact of the subsequent blocking materials on the impurities on the surface of the crawler 4 when they fall, which will cause the impurities such as stones to damage the crawler 4 after multiple impacts. When the blocking material leaves the rotating plate 14, the rotating plate 14 is reset, and the elastic ball 23 and the support rod 22 will also assist the rotating plate 14 to reset. At this time, the gas in the hollow column 242 will be reset to the fixed cylinder 21 and the elastic ball 23 through the connecting pipe, and the sliding column 243 will slide and reset with the scraper 244, the auxiliary plate 251 and other parts. Since the crawler 4 is always moving, the scraper 244 will clean the impurities at different positions on the crawler 4 with the auxiliary plate 251 when resetting. The cone rod 252 on the auxiliary plate 251 plays the role of pre-crushing the impurities on the crawler 4, and the impurities are taken out of the surface of the crawler 4 under the subsequent drive of the auxiliary plate 251. The swing rod 254, which is movably connected, can enter the gap of the crawler 4 for impact and knocking, and when encountering impurities stuck in the gap of the crawler 4, it can be lifted up by the impurities, so as to continue to clean over the impurities, and reduce the impurities in the gap of the crawler 4 through subsequent multiple knocking and cleaning.

[0048] It should be noted that the swing rod 254 is designed to have a smaller width than the gap of the crawler 4, and the crawler 4 moves slowly, and the gaps of the crawler 4 are mostly concentrated on both sides. When the scraper 244 moves to the middle of the crawler 4 with the swing rod 254, the swing rod 254 that is movably connected will be separated from the gap of the crawler 4, and the inflation and deflation of the hollow column 242 are completed quickly, so the swing rod 254 will not be stuck in the gap of the crawler 4. At the same time, the blocking material is placed just above the rotating plate 14, so it will not affect the cleaning of the crawler 4 by the scraper 244, and when the scraper 244 and the auxiliary plate 251 clean the crawler 4, they are in contact with the plane of the crawler 4.

[0049] The base 11 is provided with a spraying mechanism 30, which includes a storage box 31 fixedly installed in the base 11 and made of a flexible material, in which a spraying liquid is pre-stored, a liquid inlet pipe 33 connected to the interior and having a one-way valve is fixedly installed on one side of the storage box 31, a liquid outlet pipe 32 connected to the interior and having a one-way valve is fixedly installed on one side of the storage box 31, a liquid spraying pipe 37 is fixedly installed on one side of the base 11 through a support ring 36, and one end of the liquid outlet pipe 32 is connected to the liquid spraying pipe 37. A fixing rod 34 is fixedly installed on one side of the fixing plate 13, and a pressing plate 35 is fixedly installed on one end of the fixing rod 34.

[0050] Specifically, a stirring assembly 38 is provided in the storage box 31. The bottom of the storage box 31 is made of a hard material. The stirring assembly 38 includes a sliding block 382 that slides in the storage box 31 through a spring. A connecting rod 383 is fixedly installed on one side of the sliding block 382. A fan blade 384 made of a lightweight material is rotatably sleeved on the surface of the connecting rod 383. A second electromagnet 385 is fixedly installed on one end of the connecting rod 383. A first electromagnet 381 is fixedly installed on one side of the pressure plate 35. A spray assembly 39 is provided in the spray pipe 37. The spray assembly 39 includes a hollow guide nozzle 391 installed in the spray pipe 37. The guide nozzle 391 is in a trumpet shape. A filter screen 392 is fixedly installed between the spray pipe 37 and the guide nozzle 391. A filter screen 392 is also fixedly installed in the hollow part inside the guide nozzle 391.

[0051] During operation, after the crawler 4 completes the task of conveying the blocked material, the electric push rod 12 resets with the fixed plate 13 and other parts, and the fixed rod 34 and the pressure plate 35 are reset accordingly. One side of the pressure plate 35 is close to the storage box 31, and the first electromagnet 381 and the second electromagnet 385 are energized at this time, so that the second electromagnet 385 moves toward the direction of the first electromagnet 381 with the fan blade 384, the connecting rod 383, the sliding block 382 and the spring. The fan blade 384 is affected by the liquid when moving and rotates continuously, thereby stirring the liquid (such as preservative) in the storage box 31, so that the precipitated liquid is quickly stirred and mixed again, and then the effect is fully exerted. After the stirring is completed, the first electromagnet 381 and the second electromagnet 385 are powered off, and the sliding block 382 and the fan blade 384 and other parts are reset under the action of the spring, and the electric push rod 12 is started at the same time.

[0052] The electric push rod 12 moves and squeezes the storage box 31 with the fixed rod 34 and the pressure plate 35 through the fixed plate 13. After the storage box 31 is squeezed, the liquid inside will enter the spray pipe 37 through the liquid outlet pipe 32, and spray through the spray pipe 37 and the guide nozzle 391 to spray the liquid on the crawler 4. It should be noted that the crawler 4 is rotating slowly at this time, so as to cooperate with the spraying of the liquid. The trumpet-shaped and hollow guide nozzle 391 can guide part of the liquid to the surroundings, while the other part of the liquid is directly sprayed out through the hollow part in the middle of the guide nozzle 391, so as to spray the crawler 4 in front. The filter 392 installed at the same time can reduce the entry of impurities when the spray pipe 37 is not in use, ensuring the smoothness of the spray pipe 37. At the same time, the bottom of the pressure plate 35 will not contact the fan blades 384 and other parts when squeezing the storage box 31.

[0053] Working principle: The motor and transmission in the structural frame 1 drive the power wheel 2, which in turn drives the track 4, the support wheel 5 and the driven wheel 3 to rotate. It should be noted that at this time, the telescopic frame 7 in the bracket 6 is not in contact with the ground, and the track 4 is in direct contact with the ground. The movement of the track 4 moves the entire structural frame 1 and moves it to the breach of the dam. When the structural frame 1 moves to a suitable position through the track 4, it stops and starts several hydraulic cylinders in the bracket 6. The hydraulic cylinder drives the telescopic frame 7 to move toward the ground, thereby propping up the track 4 and the structural frame 1, so that the track 4 is no longer in contact with the ground. At this time, the materials for plugging the breach are placed on the track 4, and the transmission of the track 4 is used to quickly put the plugging materials into the breach of the dam.

[0054] After the structural frame 1 is moved to a suitable position and before the blocking material is placed, the electric push rods 12 on the two bases 11 are started, and the two electric push rods 12 are used to move the fixed plate 13, the rotating plate 14 and the buffer plate 15 in a direction close to each other, so that the two rotating plates 14 are above the crawler 4. As the blocking material begins to be placed and falls on the buffer plate 15, the buffer plate 15 will slide and retract toward the rotating plate 14 after being impacted. As the blocking material continues to fall on the buffer plate 15, under the influence of the weight of the blocking material, the rotating plate 14 will rotate with the buffer plate 15 in the direction of the fixed plate 13, thereby increasing the space between the two rotating plates 14, making it easier for the blocking material to fall onto the crawler 4 through the two rotating plates 14, and allowing the crawler 4 to move with the blocking material to the breach of the dam for blocking operations. The installation of the fixed cylinder 21, the support rod 22 and the elastic ball 23 plays a role in auxiliary support of the rotating plate 14, preventing the rotating plate 14 from excessively rotating and hitting the fixed plate 13. At the same time, when the rotating plate 14 rotates, it will move the support rod 22 into the fixed cylinder 21, and use the support rod 22 to squeeze the elastic ball 23 and the gas in the fixed cylinder 21. After the elastic ball 23 is squeezed, the gas inside will enter the fixed cylinder 21 through the shrinkage hole, and follow the gas in the fixed cylinder 21 through the vent pipe 245 into the hollow column 242. When the hollow column 242 begins to be inflated, it will push the internal sliding column 243 and scraper 244 and other parts to move away from the connecting plate 241, and use the scraper 244 to scrape and clean the surface of the crawler 4. When the blocking material leaves the rotating plate 14, the rotating plate 14 is reset, and the elastic ball 23 and the support rod 22 will also assist the rotating plate 14 to reset. At this time, the gas in the hollow column 242 will be reset to the fixed cylinder 21 and the elastic ball 23 through the connecting pipe, and the sliding column 243 will slide and reset with the scraper 244, the auxiliary plate 251 and other parts. Since the crawler 4 is always moving, the scraper 244 with the auxiliary plate 251 will clean the impurities at different positions on the crawler 4 when resetting. The cone rod 252 on the auxiliary plate 251 plays the role of pre-crushing the impurities on the crawler 4, and then the impurities are taken out of the surface of the crawler 4 under the drive of the auxiliary plate 251. The swing rod 254, which is movably connected, can enter the gap of the crawler 4 to knock and knock, and when encountering impurities stuck in the gap of the crawler 4, it can be lifted up by the impurities, so as to continue cleaning over the impurities, and through subsequent multiple knocking and cleaning, the impurities in the gap of the crawler 4 are reduced.

[0055] After the crawler 4 completes the task of conveying the blocked material, the electric push rod 12 resets with the fixed plate 13 and other parts, and the fixed rod 34 and the pressure plate 35 are reset accordingly. One side of the pressure plate 35 is close to the storage box 31, and the first electromagnet 381 and the second electromagnet 385 are energized at this time, so that the second electromagnet 385 moves toward the direction of the first electromagnet 381 with the fan blade 384, the connecting rod 383, the sliding block 382 and the spring. The fan blade 384 is affected by the liquid when moving and rotates continuously, thereby stirring the liquid in the storage box 31, so that the precipitated liquid is quickly stirred and mixed again, and the effect is fully exerted. After the stirring is completed, the first electromagnet 381 and the second electromagnet 385 are powered off, and the sliding block 382 and the fan blade 384 and other parts are reset under the action of the spring, and the electric push rod 12 is started at the same time. The electric push rod 12 moves toward and squeezes the storage box 31 with the fixing rod 34 and the pressure plate 35 through the fixing plate 13. After the storage box 31 is squeezed, the liquid inside will enter the spray pipe 37 through the liquid outlet pipe 32, and be sprayed out through the spray pipe 37 and the guide nozzle 391, spraying the liquid on the track 4.
