Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dredging equipment, and specifically relates to a pipeline dredging equipment for municipal construction. Background Art

[0002] In municipal construction and maintenance work, the pipeline system is an important part of urban infrastructure, undertaking key tasks such as drainage, water supply, and sewage disposal. However, during long-term use, pipelines are extremely prone to blockage problems, seriously affecting the normal operation of the city. In daily life, a large amount of debris such as branches, leaves, and garbage will enter the drainage pipeline along with the water flow; substances such as grease and silt in the sewage gradually accumulate on the inner wall of the pipeline, resulting in a smaller inner diameter of the pipeline; during the construction process, sand, stones, etc. accidentally entering the pipeline will also cause blockage.

[0003] However, for hard blockages such as tree roots, stones, and concrete blocks in the pipeline, the impact force of the traditional high-pressure water jet may not be sufficient to completely break or wash them away, resulting in poor dredging effects. Usually, drills or chains are added to the rotating rat head to strike the blockage during rotation to improve the wall-breaking ability. The drills are mostly welded to the rat head, so when replacing the drill, the rat head must be replaced, and the replacement operation is rather troublesome, with low replacement efficiency, and it is not convenient to select the most suitable drill according to different blockage degrees in a timely manner; when the water supply pipe of the high-pressure water jet is impacted by the water pressure in the pipeline, it is prone to excessive swing, which not only increases the wear of the water supply pipe at the pipeline opening, but also may cause the dredging operation to be unable to proceed smoothly, and even damage the equipment; at the same time, when accurately sending the rotating rat head to the pipeline blockage position, it is also difficult to achieve precise operation with existing equipment. Often, the rat head is manually stuffed into the pipeline by the operator, but it is difficult to transfer the rotating rat head in some ground conditions, especially in complex ground conditions such as deep-buried pipelines and complex surrounding environments, this problem is more prominent; during cleaning, since the high-pressure water of the water jet will wash away the grease and debris in the pipeline, some of these grease and debris will adhere to the water supply pipe, and it is not convenient for traditional equipment to clean the water supply pipe, resulting in increased wear of the water supply pipe and reduced service life of the water supply pipe.

The placing rack 201 is fixedly connected to the vehicle frame 1, and a water supply pipe 203 is wound on the unwinding cylinder 202; The buffer structure 3 includes a connecting frame 301 and a fixing frame 302. Two connecting frames 301 are fixedly connected to one side of the vehicle frame 1, and a fixing frame 302 is fixedly connected to the two connecting frames 301. A moving frame 303 is slidably connected to the fixing frame 302. A first screw rod 304 is rotatably connected to the fixing frame 302. The moving frame 303 is threadedly connected to the first screw rod 304. Two fixing rods 307 are fixedly connected to the moving frame 303. A moving block 308 is slidably connected to each of the two fixing rods 307. A guiding shaft 310 is fixedly connected to the moving frame 303. The moving block 308 is slidably connected to the guiding shaft 310. Two first springs 309 are fixedly connected to both sides of each moving block 308. The other ends of the first springs 309 are fixedly connected to the moving frame 303. A first guiding clip 311 is slidably connected to the moving block 308. Two fixing shafts 313 are fixedly connected to the moving block 308. A second spring 314 is sleeved on the outer part of the fixing shaft 313. The two ends of the second spring 314 are respectively fixedly connected to the moving block 308 and the first guiding clip 311. A water delivery pipe 203 is clamped between the two first guiding clips 311; One of the first guiding clips 311 is fixedly connected with two first guiding columns 312. The first guiding columns 312 are slidably connected with the other first guiding clip 311. A second motor 305 is fixedly connected to the fixing frame 302.

A first motor 207 is fixedly connected to the placing frame 201. The output end of the first motor 207 is fixedly connected with the winding drum 202; Start the first motor 207, the first motor 207 drives the winding drum 202 to rotate, the winding drum 202 starts to unwind the water supply pipe 203, and at the same time start the booster pump 205. The booster pump 205 pressurizes the water and transports it to the water supply pipe 203 through the water outlet pipe 206 and the rotary joint 204. The water flow rushes out from the rotary mouse head 7 at the end of the water supply pipe 203, forming a reaction force to push the rotary mouse head 7 forward in the pipeline. At the same time, since the water flow rushes out from the six water outlet holes of the rotary mouse head 7, the rotary mouse head 7 is driven to rotate at a high speed under the action of centrifugal force. The rotary mouse head 7 and the drill bit 8 dredge and clean the pipeline. During the release of the water supply pipe 203, the buffer structure 3 plays a role. When the water supply pipe 203 swings due to water pressure or other external forces, the moving block 308 slides on the fixed rod 307 and the guiding shaft 310, and the first spring 309 undergoes elastic deformation. At the same time, the first guiding clip 311 slides on the fixed shaft 313, and the second spring 314 undergoes elastic deformation to buffer the swing of the water supply pipe 203 and reduce its wear at the pipeline opening. When the pipeline dredging operation is completed, turn off the booster pump 205 to stop the water supply, and start the first motor 207 to reverse, driving the winding drum 202 to rotate to recycle the water supply pipe 203.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10As shown in the figure, the adjustment structure 4 includes a connecting plate 401 and a mounting bracket 402. A connecting plate 401 is fixedly connected to each side of each moving block 308. The same-side two connecting plates 401 are fixedly connected to the same mounting bracket 402.

A plurality of limiting holes 412 are arranged in a circumferential array on the limiting wheel 408. A fixed sleeve 409 is fixedly connected to the mounting bracket 402. A limiting rod 410 with a "dry" cross-section is slidably connected inside the fixed sleeve 409. The limiting rod 410 is inserted into the limiting hole 412.

A second screw rod 407 is rotatably connected to the adjustment bracket 404. The second screw rod 407 is threadedly connected to the sliding rod 405. A third motor 406 is fixedly connected to the adjustment bracket 404. The output end of the third motor 406 is fixedly connected to the second screw rod 407. Start the second motor 305, and its output end drives the first screw rod 304 to rotate. Since the moving frame 303 is threadedly connected to the first screw rod 304 and the moving frame 303 is slidably connected to the guide rod 306, the moving frame 303 will move along the guide rod 306, thereby adjusting the horizontal position of the water supply pipe 203 so that the water supply pipe 203 can be aligned with the pipe opening. Pull the limiting rod 410, and the third spring 411 is compressed. Rotate the adjustment bracket 404. The adjustment bracket 404 drives the rotating shaft 403 and the limiting wheel 408 to rotate. After adjusting the adjustment bracket 404 to a suitable angle, release the limiting rod 410. Under the reset action of the third spring 411, the limiting rod 410 is inserted into the corresponding limiting hole 412 on the limiting wheel 408 to fix the angle of the adjustment bracket 404. Start the third motor 406, and its output end drives the second screw rod 407 to rotate. The second screw rod 407 is threadedly connected to the sliding rod 405, causing the sliding rod 405 to slide up and down inside the adjustment bracket 404 to further finely adjust the positions of the rotating mouse head 7 and the drill bit 8 to ensure that they can accurately enter the pipe opening.

[0024] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 11As shown, the cleaning structure 5 includes a connecting shaft 501 fixedly connected to a rotating frame 502.

A cleaning cotton 507 is fixedly connected to the second guiding clip 504, and the cleaning cotton 507 abuts against the water supply pipe 203. A plurality of balls 508 are rotatably connected to the second guiding clip 504 in a circumferential array, and the balls 508 are in rolling connection with the water supply pipe 203. A fixing strip 509 is fixedly connected to the vehicle frame 1, and a diversion groove 510 is fixedly connected to the fixing strip 509. A regulating valve 511 is fixedly connected to the water outlet pipe 206, and a flushing pipe 512 is fixedly connected to the regulating valve 511. The water supply pipe 203 slides between the second guiding clips 504, and the cleaning cotton 507 abuts against the water supply pipe 203 to clean sundries, grease, etc. adhered to the water supply pipe 203 due to pipe dredging. When the water supply pipe 203 moves, it drives the second guiding clip 504 to move, and then drives the rotating frame 502 to rotate around the connecting shaft 501. The torsion spring 503 plays a buffering role to reduce the swing of the water supply pipe 203. At the same time, the balls 508 on the second guiding clip 504 are in rolling connection with the water supply pipe 203 to reduce the friction when the water supply pipe 203 moves. If it is necessary to flush the recycled pipe, the adjusting frame 404 and the sliding rod 405 can be rotated to the vertical state through the adjusting structure 4 first, and then the regulating valve 511 is started to control the flushing pipe 512 to discharge water for flushing. The winding structure 2 is cooperated to wind up the water supply pipe 203. At this time, the cleaning cotton 507 on the second guiding clip 504 cleans and wipes the surface of the water supply pipe 203, and the flushing water is discharged through the diversion groove 510.

[0025] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 13 and Figure 14As shown, a rotating rat head 7 is rotatably connected to the end of the water supply pipe 203. The mounting structure 6 includes a socket 601 and a slot 602. The socket 601 is fixedly connected to the drill bit 8, and the slot 602 is provided on the rotating rat head 7. The socket 601 and the slot 602 are inserted into each other. A slip ring 603 is slidably connected inside the socket 601. A plurality of insertion rods 604 are fixedly connected to the slip ring 603. The insertion rods 604 are slidably connected to the rotating rat head 7. A plurality of locking holes 605 are provided on the socket 601. The insertion rods 604 are inserted into the locking holes 605. A plurality of fixing columns 606 are fixedly connected inside the rotating rat head 7. A fifth spring 607 is sleeved outside the fixing columns 606. Two ends of the fifth spring 607 are respectively fixedly connected to the slip ring 603 and the rotating rat head 7. A plurality of connecting rods 608 are fixedly connected to the slip ring 603. The connecting rods 608 are slidably connected to the rotating rat head 7. The same lifting ring 609 is fixedly connected to the plurality of connecting rods 608. According to the needs of pipeline dredging, select a drill bit 8 of a suitable style, align the socket 601 on the drill bit 8 with the slot 602 on the rotating rat head 7 and insert it. Pull the connecting rod 608 through the lifting ring 609 to drive the slip ring 603 to slide. At this time, the slip ring 603 slides into the socket 601, the fifth spring 607 is compressed, and at the same time the insertion rods 604 contract. When the socket 601 is completely inserted into the slot 602, rotate the socket 601. The slip ring 603 is reset under the action of the fifth spring 607, and the insertion rods 604 are inserted into the locking holes 605 on the socket 601 to complete the installation of the drill bit 8. If it is necessary to disassemble the drill bit 8, the slip ring 603 can be pulled through the lifting ring 609 to make the insertion rods 604 disengage from the locking holes 605, and then rotate the drill bit 8 and the socket 601 to pull out the drill bit 8.

[0026] When the present invention is in use, first, according to the needs of pipeline dredging, select a drill bit 8 of a suitable style, align the socket 601 on the drill bit 8 with the slot 602 on the rotating rat head 7 and insert it. Pull the connecting rod 608 through the lifting ring 609 to drive the slip ring 603 to slide. At this time, the slip ring 603 slides into the socket 601, the fifth spring 607 is compressed, and at the same time the insertion rods 604 contract. When the socket 601 is completely inserted into the slot 602, rotate the socket 601. The slip ring 603 is reset under the action of the fifth spring 607, and the insertion rods 604 are inserted into the locking holes 605 on the socket 601 to complete the installation of the drill bit 8. If it is necessary to disassemble the drill bit 8, the slip ring 603 can be pulled through the lifting ring 609 to make the insertion rods 604 disengage from the locking holes 605, and then rotate the drill bit 8 and the socket 601 to pull out the drill bit 8; Then, start the second motor 305. The output end of the second motor drives the first screw rod 304 to rotate. Since the moving frame 303 is threadedly connected to the first screw rod 304 and the moving frame 303 is slidably connected to the guide rod 306, the moving frame 303 will move along the guide rod 306, thereby adjusting the horizontal position of the water supply pipe 203 so that the water supply pipe 203 can be aligned with the pipe opening. Pull the limit rod 410, and the third spring 411 is compressed. Rotate the adjustment frame 404. The adjustment frame 404 drives the rotating shaft 403 and the limit wheel 408 to rotate. After adjusting the adjustment frame 404 to an appropriate angle, release the limit rod 410. Under the reset action of the third spring 411, the limit rod 410 is inserted into the corresponding limit hole 412 on the limit wheel 408 to fix the angle of the adjustment frame 404. Start the third motor 406. The output end of the third motor drives the second screw rod 407 to rotate. The second screw rod 407 is threadedly connected to the slide rod 405, so that the slide rod 405 slides up and down in the adjustment frame 404 to further finely adjust the positions of the rotating rat head 7 and the drill bit 8 to ensure that they can accurately enter the pipe opening; Secondly, start the first motor 207. The first motor 207 drives the reel 202 to rotate, and the reel 202 starts to unwind the water supply pipe 203. At the same time, start the booster pump 205. The booster pump 205 pressurizes the water and transports it to the water supply pipe 203 through the water outlet pipe 206 and the rotary joint 204. The water flow rushes out from the rotary rat head 7 at the end of the water supply pipe 203 to form a reaction force, which pushes the rotary rat head 7 to move forward in the pipe. At the same time, since the water flow rushes out from the six water outlet holes of the rotary rat head 7, it drives the rotary rat head 7 to rotate at a high speed under the action of centrifugal force. The rotary rat head 7 and the drill bit 8 dredge and clean the pipe. During the process of unwinding the water supply pipe 203, the buffer structure 3 plays a role. When the water supply pipe 203 swings due to water pressure or other external forces, the moving block 308 slides on the fixed rod 307 and the guide shaft 310, and the first spring 309 undergoes elastic deformation. At the same time, the first guide clamp 311 slides on the fixed shaft 313, and the second spring 314 undergoes elastic deformation to buffer the swing of the water supply pipe 203 and reduce its wear at the pipe opening. When the pipe dredging operation is completed, turn off the booster pump 205 to stop the water supply, and start the first motor 207 to reverse, driving the reel 202 to rotate to recover the water supply pipe 203; Finally, the water supply pipe 203 slides between the second guiding clips 504, and the cleaning cotton 507 abuts against the water supply pipe 203 to clean the sundries, grease, etc. adhering to the water supply pipe 203 due to pipeline dredging. When the water supply pipe 203 moves, it drives the second guiding clip 504 to move, and further drives the rotating frame 502 to rotate around the connecting shaft 501. The torsion spring 503 plays a buffering role to reduce the swing of the water supply pipe 203. At the same time, the balls 508 on the second guiding clip 504 are in rolling connection with the water supply pipe 203 to reduce the friction when the water supply pipe 203 moves. If it is necessary to flush the recycled pipeline, the adjusting frame 404 and the sliding rod 405 can be rotated to the vertical state through the adjusting structure 4 first, and then the control valve 511 is started to control the water outlet of the flushing pipe 512 for flushing. The winding structure 2 is used to wind up the water supply pipe 203. At this time, the cleaning cotton 507 on the second guiding clip 504 cleans and wipes the surface of the water supply pipe 203, and the flushing water is discharged through the diversion groove 510.
