Description

Technical Field

[0001] The invention relates to the technical field of tunnel equipment, in particular to a drilling and scraping trolley for inclined shaft construction and a scraping assembly thereof. Background Art

[0002] Pumped storage power stations and conventional hydropower stations generally use underground tunnels to divert water. Due to the need for concentrated water head, the height difference between the head and the end of the water diversion tunnel is large, and an inclined shaft needs to be set up. The water diversion inclined shaft generally consists of an upper curved section, an inclined straight section, and a lower curved section. Due to the large inclination of the tunnel, the traditional shield method and the trolley drilling and blasting method cannot meet the on-site excavation requirements for the inclined straight section. Such a multifunctional inclined shaft excavation trolley came into being. The excavation of the inclined straight section first requires drilling and blasting of the tunnel face, and then slag removal. The equipment needs to have mechanized construction capabilities for multiple processes such as drilling, slag removal, and anchoring.

[0003] The application number is CN202211108146.9, which is a construction device for drilling and removing slag for inclined shaft expansion, comprising a frame assembly, a fixing mechanism is arranged on the outside of the frame assembly, a hydraulic system is arranged inside the frame assembly, a video monitoring system is arranged at the front end of the frame assembly, a moving mechanism is arranged inside the frame assembly, and a rotary oil cylinder connected to the hydraulic system is arranged at the front end of the moving mechanism. The invention has the advantages of high construction safety, low construction difficulty, high construction quality and wide application range.

[0004] The application number is CN202120743023.7, which is a telescopic slag removal device for inclined shaft construction. It includes an excavation trolley with multi-layer platforms fixedly connected by a steel frame. A slide rail frame is provided at the bottom of the multi-layer platform, and the end of the slide rail frame is hinged to the hydraulic excavation arm, which can slide and rotate on the slide rail frame. A support inclined plate is provided on the inner side of the bottom of the multi-layer platform of the excavation trolley, and rollers are provided at both ends of the bottom of the support inclined plate, and a track is provided under the roller. The slide rail frame and the excavation arm are provided, so that the excavation arm can be extended and flipped as needed during the excavation process, which can better fit the working surface and facilitate construction.

[0005] However, during the use of the above-mentioned device, when the bucket is used to scrape slag, the bucket teeth often rub against the slag. After long-term use, the bucket teeth will heat up and be easily damaged. In addition, when the bucket shovels large slag, the bucket teeth often come into hard contact with the slag. Therefore, the bucket teeth are easily replaced due to damage. At the same time, the light in the inclined shaft is dim, and when the staff uses the remote control to operate the equipment, the posture of the bucket is easy to be incorrect, which makes the bucket prone to leakage and easily causes safety accidents. In addition, when the inclined shaft is dry, the use of the bucket will cause dust to fly, further affecting the line of sight. When the slag is transported out, a large amount of soil is likely to remain in the slag shoveled by the bucket. The remaining soil is easy to adhere to the conveyor belt when it is transported out through the conveyor belt, which increases the load of the conveyor belt and makes it easy to be damaged.

Therefore, the drill arm system 2 will also move with the slide 402, and the two sections of the slide track 401 are conducive to ensuring the stability of the movement of the slide 402. With the assistance of the lifting cylinder, the slide track 401 and the slide 402, the position of the drill arm system 2 can be adjusted conveniently and stably, making the equipment more convenient for inclined well construction.

[0037] The drilling arm system 2 includes a rotary support frame 201, which is rotatably arranged at the side end of a slide 402. A driving motor 202 is arranged on the slide 402. The output end of the driving motor 202 is connected to the rotary support frame 201 through a gear set for transmission. Drill arms 203 are arranged on both sides of the rotary support frame 201. A drilling arm fixed arm 204 is arranged between the drilling arm 203 and the rotary support frame 201. The drilling arm fixed arm 204 is rotatably connected to the rotary support frame 201. A swing cylinder 205 is also arranged between the drilling arm fixed arm 204 and the rotary support frame 201. The drilling arm 203 is connected to the rotary support frame 201 through a gear set. A drill rod 206 is provided on 03. With the assistance of the driving motor 202 and the gear set, the slewing support frame 201 can be rotated to adjust the positions of the drill arms 203 on both sides. The drill arm fixed arm 204 can be deflected with the assistance of the swing cylinder 205, so that the drill arm fixed arm 204 can be adjusted in angle. When carrying out inclined well construction, the end of the drill rod 206 is aligned with the processing position of the wall in the inclined well, and then the drill rod 206 is rotated by the driving device in the drill rod 206. The wall is processed by the rotation of the drill rod 206 to make the slag on the wall fall off.

[0038] The present embodiment also discloses a slag removal assembly of a drilling and scraping trolley for inclined shaft construction, wherein the slag removal assembly 3 comprises a bucket 301 and a telescopic arm 316, wherein the bucket 301 is provided with bucket teeth 302, the telescopic arm 316 is provided on the frame body 102, a slag removal working arm 317 is provided at the side end of the telescopic arm 316, a slewing support plate 318 is provided at the output end of the telescopic arm of the telescopic arm 316, the slag removal working arm 317 is provided on the slewing support plate 318, a slewing oil cylinder 319 is provided in the slewing support plate 318, a plurality of adjusting oil cylinders 320 are provided on the slag removal working arm 317, and the bucket 301 is provided on the slag removal working arm 317. At the end, the slag scraping working arm 317 can be moved along the telescopic arm 316 with the assistance of the telescopic arm 316, so that the working range of the slag scraping working arm 317 is expanded, and the slag scraping working arm 317 can be adjusted at multiple angles with the assistance of multiple adjusting cylinders 320, and the rotary cylinder 319 can drive the rotary support plate 318 to rotate, thereby rotating the slag scraping working arm 317 and adjusting the posture of the bucket 301. When scraping, the bucket 301 and the bucket teeth 302 are used to assist in shoveling up the slag and moving it to the conveyor belt at the lower end of the frame system 1 to send it out of the inclined shaft, thereby improving the convenience of equipment use.

[0039] During use, tracks are laid in the inclined shaft under construction, and the rack system 1 is set on the track in the inclined shaft with the assistance of the track walking wheels 101. The rack system 1 can be moved along the track in the inclined shaft with the assistance of an external winch, a pull rope and multiple sets of pulley blocks 103. After the rack system 1 moves to the processing position, the support legs 104 are extended upward, and the upper ends of the support legs 104 are against the top of the inclined shaft, so that the rack system 1 is auxiliary fixed to ensure the stability of the rack system 1 during processing.

[0040] When processing an inclined well, the slide 402 is moved along the slide track 401 with the assistance of the lifting cylinder, so that the drill rod 206 in the drill arm system 2 is close to the wall in the inclined well. With the assistance of the driving motor 202 and the gear set, the slewing support frame 201 can be rotated to adjust the position of the drill arms 203 on both sides.

When constructing an inclined well, the end of the drill rod 206 is aligned with the processing position of the wall in the inclined well, and then the drill rod 206 is rotated by the driving device in the drill rod 206. The wall is processed by the rotation of the drill rod 206, so that the equipment can excavate and drill holes for anchor bolts on the wall of the inclined well, which is beneficial for subsequent blasting work.

[0041] After the blasting of the face is completed, part of the slag will be discharged through the slag chute of the inclined shaft, and the remaining slag needs to be removed. During the removal operation, the slag removal working arm 317 can be moved along the telescopic arm 316 with the assistance of the telescopic arm 316, so that the working range of the slag removal working arm 317 is expanded, and the slag removal working arm 317 can be adjusted at multiple angles with the assistance of multiple adjusting cylinders 320. The rotary cylinder 319 can drive the rotary support plate 318 to rotate, thereby rotating the slag removal working arm 317 and adjusting the posture of the bucket 301. During the removal operation, the bucket 301 and the bucket teeth 302 are used to assist in shoveling up the slag and moving it to the conveyor belt at the lower end of the frame system 1 to send it out of the inclined shaft.

[0042] Embodiment 2

[0043] In the above-mentioned embodiment 1, the scraping assembly of the drilling and scraping trolley for inclined shaft construction disclosed in the embodiment 1 is used. When the bucket 301 is used to scrape the slag, the bucket teeth 302 often rub against the slag. After long-term use, the bucket teeth 302 will heat up and be easily damaged. In addition, when the bucket 301 is used to scrape large slag, the bucket teeth 302 often come into hard contact with the slag. Therefore, the bucket teeth 302 are easily replaced due to damage. At the same time, the light in the inclined shaft is dim. When the staff uses the remote control to operate the equipment, it is easy to make the posture of the bucket 301 incorrect, causing the bucket 301 to be damaged. 1 is prone to leakage, which can easily cause safety accidents. When the inclined shaft is dry, the bucket 301 will cause dust to fly when in use, further affecting the line of sight. When the slag is transported out, a large amount of soil is likely to remain in the slag shoveled by the bucket 301. The remaining soil is likely to adhere to the conveyor belt when it is transported out through the conveyor belt, increasing the load of the conveyor belt and making it easy to be damaged. In order to protect the bucket teeth 302 during the slag removal process, avoid the leakage when the bucket 301 moves the slag, and ensure the stable operation of the conveyor belt, the following improvement plan is proposed:

[0044] like Figures 1 to 9 As shown, a groove 303 is provided on the bucket tooth 302, an auxiliary tooth 304 is rotatably provided in the groove 303, a hydraulic push rod 305 is provided at the bottom end of the groove 303, the output end of the hydraulic push rod 305 is provided at the lower end of the auxiliary tooth 304, a connecting pipe 306 is provided at the side end of the groove 303, a cavity 307 is provided at the bottom of the bucket 301, a water filter hole 308 is provided at the cavity 307 on the bucket 301, a baffle 309 is slidably provided in the cavity 307, and a hole matching the water filter hole 308 is provided on the baffle 309, the connecting pipe 306 passes through the bucket 301 and is inserted into the cavity 307, a push rod 310 is provided on the side of the connecting pipe 306 close to the baffle 309, and a pressure sensor is provided on the bucket tooth 302. When the bucket 301 shovels up slag, the slag can be detected with the assistance of the pressure sensor on the bucket tooth 302. The pressure between the auxiliary teeth 304 and the bucket teeth 302, after the hydraulic push rod 305 is started, the output end of the hydraulic push rod 305 will drive the auxiliary teeth 304 to rise and fall, and the auxiliary teeth 304 are rotatably connected to the bucket teeth 302, so the side of the auxiliary teeth 304 away from the hydraulic push rod 305 will also rise and fall, and when the auxiliary teeth 304 close to the side of the bucket 301 descend, the side end of the auxiliary teeth 304 descends and moves laterally, which will squeeze the connecting pipe 306, so that the push rod 310 at the other end of the connecting pipe 306 extends, and then the baffle 309 moves. When the hole on the baffle 309 coincides with the water filter hole 308, the soil and water in the bucket 301 can be discharged from the water filter hole 308, reducing the soil brought up by the bucket 301 when shoveling up slag, so that the soil and water remain in the inclined shaft and are conveniently discharged with the assistance of external water pumps and pipelines, reducing the impact on the conveyor belt.

[0045] The side of the connecting tube 306 close to the auxiliary teeth 304 is sealed, and the side of the connecting tube 306 close to the auxiliary teeth 304 is elastic. Hydraulic oil is arranged in the connecting tube 306, and the connecting tube 306 and the push rod 310 are slidingly connected through the piston plate. When the auxiliary teeth 304 squeeze the elastic side of the connecting tube 306, the hydraulic oil pressure in the connecting tube 306 will increase, so that the push rod 310 on the other side of the connecting tube 306 extends out. When the auxiliary teeth 304 no longer squeeze the connecting tube 306, since the side of the connecting tube 306 close to the auxiliary teeth 304 is elastic, when the connecting tube 306 rebounds from the squeezed position, the push rod 310 retracts into the connecting tube 306.

[0046] There are multiple bucket teeth 302, and the hydraulic push rod 305 in each bucket tooth 302 is controlled separately. The side of the bucket tooth 302 away from the bucket 301 is provided with an arc, and the side of the auxiliary tooth 304 away from the bucket 301 is also provided with an arc. The output end of the hydraulic push rod 305 is located at the lower end of the auxiliary tooth 304 close to the bucket 301. When the bucket 301 is used to shovel large slag, when the bucket 301 is forcibly inserted into the bottom of the slag, it will generate excessive friction on the bucket tooth 302, which is easy to The bucket tooth 302 is damaged. At this time, multiple auxiliary teeth 304 and hydraulic push rods 305 are used to cooperate. Specifically, when the bucket tooth 302 is inserted into the gap between the slag and the ground, the hydraulic push rod 305 acts to make the auxiliary teeth 304 lift the slag by the lever principle, which makes it easy for the bucket 301 to be inserted. When the multiple auxiliary teeth 304 are alternately lifted, the slag will be pushed toward the bucket 301, which is conducive to the bucket 301 to shovel large slag, thereby improving the convenience of equipment use.

[0047] A nozzle 311 is provided at the upper end of the bucket 301, and the nozzle 311 is rotatably connected to the bucket 301. A motor 312 is provided at the outer side of the bucket 301, and the output end of the motor 312 is connected to the nozzle 311. A plurality of nozzles 313 are provided on the nozzle 311. A connecting sleeve 314 is rotatably provided on the nozzle 311, and a water supply pipe 315 is provided on the connecting sleeve 314. The water supply pipe 315 is connected to the nozzle 311 through the connecting sleeve 314. When the inclined shaft is dry, the bucket 301 will cause dust to fly when scraping, so through The water supply pipe 315 delivers water into the nozzle 311, and the water in the nozzle 311 is sprayed out through the nozzle 313. The water sprayed from the nozzle 313 can not only suppress the flying of dust, but also reduce the heat generated by friction when the water sprayed from the nozzle 313 falls on the sand and gravel. In the process of shoveling sand and gravel by the bucket 301, the bucket teeth 302 can be protected, and the water sprayed from the nozzle 313 can also clean the inside of the bucket 301. When the motor 312 is started, the nozzle 311 can be deflected, thereby changing the water spraying position of the nozzle 313.

[0048] During use, when bucket 301 is used to shovel slag, the pressure between the slag and the bucket tooth 302 can be detected with the assistance of the pressure sensor on the bucket tooth 302, and the state of the slag shoveled by bucket 301 can be indirectly judged. That is, when the slag shoveled by bucket 301 is large slag, the detection value of the pressure sensor will steadily rise and then tend to be stable. At this time, the surface slag volume is larger than bucket 301 or the slag has not completely entered bucket 301. The detection value of the pressure sensor will steadily rise and then drop to zero, indicating that the slag volume is moderate and enters the bottom of bucket 301. If the slag shoveled by bucket 301 is small slag, the detection value of the pressure sensor will sometimes increase and sometimes decrease.

[0049] During the scraping process of bucket 301, if the detection value of the pressure sensor fluctuates unstably, the equipment determines that bucket 301 is scraping small slag stones. When scraping small slag stones, a large amount of soil is mixed in the small slag stones. During the scraping process of bucket 301, dust is easily caused. At this time, the equipment controls the water supply pipe 315 to supply water to the nozzle 311, and the nozzle 313 starts to spray water to flush the slag stones in the bucket 301. At the same time, the equipment controls the motor 312 to start, so that the nozzle 311 reciprocates. During the reciprocating rotation of the nozzle 311, the water spraying area of ​​the nozzle 313 is increased, which is beneficial to the comprehensive flushing of the slag stones in the bucket 301.

[0050] In the above process, since the hydraulic push rod 305 is not started, the holes on the baffle 309 are in an overlapping state with the water filter hole 308, and the soil washed down by the slag can be discharged through the water filter hole 308. When the bucket 301 pours the sand and gravel onto the conveyor belt, the amount of soil in the sand and gravel is reduced, avoiding excessive soil adhesion on the conveyor belt to cause excessive pressure on the conveyor belt, and avoiding soil adhesion on the conveyor belt to reduce its friction, thereby protecting the conveyor belt in disguised form.

[0051] When the bucket 301 pours the sand and gravel onto the conveyor belt, due to the continuous water spraying of the nozzle 313, the water flow sprayed by the nozzle 313 can also assist in the discharge of the sand and gravel in the bucket 301, thereby reducing the residual sand and gravel in the bucket 301.

[0052] During the slag removal process of the bucket 301, if the detection value of the pressure sensor gradually rises and exceeds the threshold and there is no downward trend, the equipment determines that the bucket 301 is slag removal of large slag stones at this time. At this time, the equipment controls the motor 312 to operate and rotate the nozzle 311 to rotate the nozzle 313 to turn the direction of the bucket teeth 302, so that the water sprayed by the nozzle 313 is biased towards the bucket teeth 302. At this time, the hard friction between the bucket teeth 302 and the large slag stones will cause the temperature of the bucket teeth 302 to rise. If the temperature is too high, it will affect the service life of the bucket teeth 302. The water sprayed by the nozzle 313 is biased towards the bucket teeth 302. When the water sprayed by the nozzle 313 flows down along the large slag stones to the bucket teeth 302, it can cool the bucket teeth 302 to ensure that the bucket teeth 302 will not be damaged due to excessive friction temperature rise.

[0053] Furthermore, in order to ensure that the bucket 301 can shovel up large slag, the equipment synchronously controls the hydraulic push rod 305 to reciprocate, so that the auxiliary teeth 304 close to the side of the bucket 301 reciprocate and rise and fall, and the multiple auxiliary teeth 304 are divided into two groups and rise and fall alternately, that is, when the first, third and fifth auxiliary teeth 304 close to the side of the bucket 301 rise, the second, fourth and sixth auxiliary teeth 304 close to the side of the bucket 301 descend. Through the principle of lever and the above-mentioned action, on the one hand, the gap between the large slag and the bucket teeth 302 can be enlarged, which is beneficial to the insertion of the bucket 301. On the other hand, the surface of the slag is uneven, and when the auxiliary teeth 304 are alternately raised and lowered, the slag will be pushed when the bucket 301 is flattened. The stone slowly enters the bucket 301. The principle is that when the auxiliary teeth 304 away from the bucket 301 are raised or lowered, when the auxiliary teeth 304 away from the side of the bucket 301 rise, the auxiliary teeth 304 away from the side of the bucket 301 moves laterally toward the side of the bucket 301, and when it contacts the lower side of the slag, it will generate a thrust to the slag in the direction of the bucket 301. When the auxiliary teeth 304 away from the side of the bucket 301 descend, the auxiliary teeth 304 are away from the slag, and no thrust is generated to move the slag away from the bucket 301. Through such fine-tuning and shoveling of the bucket 301, it is beneficial for large slag to enter the bucket 301 stably, and the bucket teeth 302 can be protected to a certain extent.

[0054] When the auxiliary teeth 304 are lifted and lowered back and forth, the elastic side of the connecting pipe 306 will be squeezed and rebounded back and forth, so the push rod 310 will move back and forth, causing the baffle 309 to move back and forth in the cavity 307. In this process, the mud blocking the water filter hole 308 can be cleaned, and the water filter hole 308 can be closed to accumulate water in the bucket 301. When the water in the bucket 301 accumulates, the water will penetrate into the gap between the large sand and gravel and the bucket 301, which can reduce the friction between the large slag and the bucket 301. On the one hand, it can make the large sand and gravel easily enter the bucket 301. On the other hand, when the large sand and gravel are discharged, it can avoid the damage of the large sand and gravel to the inner wall of the bucket 301 due to friction.

[0055] After the large sand and gravel completely enter the bucket 301, the detection value of the pressure sensor will drop to zero. In order to prevent the large sand and gravel from escaping due to excessive inertia when the bucket 301 moves, the equipment controls all the hydraulic push rods 305 to operate synchronously, and at the same time, the water supply pipe 315 stops supplying water, so that the auxiliary teeth 304 are lifted away from one side of the bucket 301, and multiple auxiliary teeth 304 are raised at the bucket teeth 302 to form a barrier, ensuring the stability of the large slag in the bucket 301, and preventing the large slag from being thrown out of the bucket 301 when the bucket 301 moves significantly. In this process, the elastic side of the connecting pipe 306 will continue to be squeezed, so the holes on the baffle 309 are staggered with the water filter hole 308, and the baffle 309 is used to assist in strengthening the structural stability of the water filter hole 308 to avoid compression deformation of the water filter hole 308.

[0056] When large slag is poured out by the bucket 301, if the large slag is directly poured out by the bucket 301 and rolls onto the conveyor belt, it is easy to cause damage to the conveyor belt. At this time, the large slag will contact the auxiliary teeth 304 before being poured out by the bucket 301 by tilting and sliding. At this time, the detection value of the pressure sensor increases. When the detection value of the pressure sensor is stable, it indicates that the auxiliary teeth 304 have contacted the large slag and prevented the large slag from sliding. At this time, the equipment controls the hydraulic push rod 305 to operate slowly, so that the inclination angle of the auxiliary teeth 304 changes slowly, thereby causing the large slag to slide slowly onto the conveyor belt, reducing its damage to the conveyor belt and improving the stability of the equipment.

[0057] The main functions realized by the present invention are as follows: by setting auxiliary teeth 304, hydraulic push rod 305, motor 312, nozzle 311 and pressure sensor and other components, the state of the sand and gravel shoveled by the bucket 301 can be indirectly detected with the assistance of the pressure sensor. If the bucket 301 shovels small slag, the nozzle 311 is assisted by the motor 312 to reciprocate, so that the water sprayed by the nozzle 313 can wash the sand and gravel, remove dust and assist in the discharge of sand and gravel in the bucket 301. If the bucket 301 shovels large slag, the hydraulic push rod 305 is used to make multiple auxiliary teeth 304 alternately rise and fall. With the assistance of the lever principle, Increasing the gap between large sand and gravel and the bucket teeth 302 is conducive to the insertion of the bucket 301. When the bucket 301 flattens the large sand and gravel, it can also assist the large sand and gravel to enter the bucket 301. At the same time, when the bucket 301 moves significantly, the assistance of the auxiliary teeth 304 can prevent the large slag from being thrown out due to inertia. At the same time, when the large slag is discharged, the impact force of the large slag on the conveyor belt is reduced with the assistance of the auxiliary teeth 304. In the process of shoveling large slag, the water sprayed by the nozzle 313 can not only cool the bucket teeth 302, but also reduce the friction between the large slag and the bucket 301, which is conducive to the stable shoveling of large slag.
