Description

Technical Field

[0001] The present invention relates to the technical field of construction hoisting, and particularly to an auxiliary hoisting device and method for municipal pipe well construction. Background Technique

[0002] Municipal pipe wells are an important part of the urban underground pipeline system, mainly used to accommodate and protect various underground pipeline facilities, such as water supply and drainage pipes, power cables, communication lines, etc. These pipe wells are usually located on both sides of the road or under the central isolation belt to facilitate the inspection, maintenance, and management of underground pipelines. When it is necessary to transport construction materials into the pipe well, hoisting equipment is required to transport the construction materials.

[0003] Publication No. CN115465775A discloses a hydraulic pipe hoisting device in a pipe well, including a hydraulic support device and a cable. The hydraulic support device includes a number of hydraulic support rods, and the number of hydraulic support rods are arranged at intervals along the circumference of the hydraulic support device; the cable is connected to the hydraulic support device. When using the hoisting device of the present invention to hoist a pipe, the hydraulic support device is sent into the pipe through the cable, and the elongation length of the hydraulic support rods is controlled so that the movable ends of all hydraulic support rods tightly abut against the inner wall of the pipe. By using the friction between the movable ends of the hydraulic support rods and the pipe, the hydraulic support device can fix the pipe, and the hoisting work of the pipe can be realized by taking in and paying out the cable. There is no need to make lifting lugs, which can reduce material and labor waste and reduce damage to the pipe; and since the hydraulic support rods can adjust the elongation length, this hoisting device can be used for hoisting pipes with different diameters and can be used for a long time.

[0004] Although the above application and the prior art can hoist pipes and can adapt to hoisting of different pipe diameters, when hoisting an overly long pipe in the above application and the prior art, the length of the overly long pipe will be greater than the diameter of the pipe well, which will cause the pipe well to not be quickly hoisted into the pipe well. And when hoisting the pipe obliquely, when the pipe descends, it will cause the pipe to rotate inside the pipe well, which will cause the pipe to collide with the inner wall of the pipe well, resulting in damage to the pipe. And when the pipe is placed obliquely, during the descending process, one end of the cable will be overloaded, which will cause the cable to be damaged after long-term use. Therefore, the present invention provides an auxiliary hoisting device and method for municipal pipe well construction. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an auxiliary hoisting device and method for municipal pipe well construction, which have the advantages of long hoisting, preventing rotation, and preventing excessive pressure, and solve the problems that in the above application and the prior art, when hoisting an overly long pipeline, the length of the overly long pipeline is greater than the diameter of the pipe well, resulting in the pipe well not being able to be quickly hoisted into the pipe well, and when the pipeline is hoisted obliquely, when the pipeline descends, the pipeline will rotate inside the pipe well, resulting in the pipeline colliding with the inner wall of the pipe well, and then the pipeline is damaged, and when the pipeline is placed obliquely, during the descent process, one end of the cable will be overloaded, and over time, the cable will be damaged.

[0007] Furthermore, the hoisting assembly further includes a second hoisting rope and a third hoisting rope arranged inside the driving box, and the bottoms of the second hoisting rope and the third hoisting rope are respectively fixedly connected to the tops of the two placing frames.

[0008] Furthermore, a fixing assembly is arranged inside the two placing frames, and the fixing assembly includes a screw hole opened on one side of the two placing frames and a clamping plate slidably connected inside the two placing frames. One end of the clamping plate is rotatably connected to a screw rod, the screw rod is threadedly connected inside the screw hole, and the end of the screw rod away from the clamping plate is fixedly connected to a turning handle.

[0009] Furthermore, the tilting assembly includes a driving motor fixedly connected to the inside of the driving box and a second rotating rod rotatably connected to the inside of the driving box, the output end of the driving motor is fixedly connected to the first rotating rod, the surface of the first rotating rod is fixedly connected to the driving gear, the surface of the second rotating rod is fixedly connected to the driven gear, the driving gear and the driven gear are meshed for transmission, the surfaces of the first rotating rod and the second rotating rod are fixedly connected to the storage rollers, and the tops of the second and third hanging ropes are fixedly connected to the surfaces of the two storage rollers respectively.

[0010] Furthermore, the anti-rotation component includes two support blocks fixedly connected to the top of the drive box, a rotating plate is rotatably connected between the two support blocks, one end of the rotating plate is fixedly connected to a roller frame, the inside of the roller frame is rotatably connected to a third rotating rod, and the surface of the third rotating rod is fixedly connected to a rolling wheel located inside the roller frame.

[0011] Furthermore, the anti-rotation assembly also includes a support plate fixedly connected to the rotating plate and the back, the bottom of the support plate is fixedly connected to a spring, and the bottom of the spring is fixedly connected to the top of the drive box.

[0012] Furthermore, the anti-skew component includes a driving sprocket fixedly connected to the surface of the third rotating rod and a support frame fixedly connected to one end of the rotating plate, the support frame is internally rotatably connected to a fourth rotating rod, the surface of the fourth rotating rod and located outside the support frame is fixedly connected to a driven sprocket, the driving sprocket and the driven sprocket are transmitted through a chain, and the surface of the fourth rotating rod and located inside the support frame is fixedly connected to a driving gear.

[0013] Furthermore, the anti-tilt assembly also includes a water storage box, a water diversion box, and a rectangular tooth plate slidably connected to the inside of the drive box. The water storage box and the water diversion box are connected by a connecting pipe. The opposite surfaces of the rectangular tooth plate are fixedly connected with a sealing plate. The sealing plate is slidably connected to the inside of the water storage box and the water diversion box. The rectangular tooth plate is engaged with the driving gear for transmission.

[0014] Furthermore, a counterweight is fixedly connected to the top of the base, an adjusting cylinder is fixedly connected to the top of the fixing seat, and the top of the adjusting cylinder is hinged to the bottom of the adjusting frame.

[0015] The present invention also provides an auxiliary hoisting method for municipal pipe well construction, which specifically includes the following steps: Step 1: Place the material to be hoisted in the two placement frames. If the material is too long, tilt it by using the tilting component. Step 2: Then, use the hoisting assembly to hoist the material into the pipe well. The edge of the pipe well drives the anti-rotation assembly, causing the anti-rotation assembly to support the drive box, preventing the material from rotating during the long descent of the material, and thus avoiding damage to the material caused by collision. Step 3: During the descent of the drive box, the anti-rotation assembly drives the anti-inclination assembly to operate, causing the anti-inclination assembly to redistribute the weight inside the drive box, thereby preventing damage to the first lifting rope. Step 4: When the placement frame descends to the bottom of the pipe well, use the inclination assembly to restore the material to its initial state, thereby facilitating the removal of the material.

[0016] Compared with the prior art, the present invention provides an auxiliary hoisting device and method for municipal pipe well construction, having the following beneficial effects: 1. For the auxiliary hoisting device and method for municipal pipe well construction, by the combined use of the hoisting assembly and the inclination assembly, place the material to be hoisted into the two placement frames. Then, start the drive motor. The drive motor drives the driving gear to rotate through the first rotating rod, causing the driven gear to drive the second rotating rod to rotate. Thus, the storage roller drives the second lifting rope to rise and the third lifting rope to descend. The second lifting rope and the third lifting rope drive the corresponding placement frames to rise and descend respectively, thereby tilting the hoisted material inside the placement frame. Then, start the drive motor. The drive motor drives the first lifting rope to descend through the drive rod. Thus, the first lifting rope drives the hoisted material to descend into the pipe well through the drive box, thereby achieving the effect of long-distance hoisting.

[0017] 2. For the auxiliary hoisting device and method for municipal pipe well construction, by the combined use of the hoisting assembly and the anti-rotation assembly, when the first lifting rope drives the drive box to descend, the rolling wheel at the bottom of the rotating plate first contacts the edge of the top of the pipe well. When the drive box continues to descend, the rolling wheel drives the rotating plate to rotate inside the support block through the roller frame, causing the rotating plate to drive the spring to stretch through the support plate. When the rolling wheel contacts the inner wall of the pipe well, the spring is no longer stretched by the support plate and gradually returns to its original state. Thus, the rolling wheel always contacts the inner wall of the pipe well. Therefore, when the drive box continues to descend, the drive box will not drive the hoisted material inside the placement frame to rotate through the second lifting rope and the third lifting rope, thereby achieving the effect of preventing rotation.

[0018] 3. For the auxiliary hoisting device and method for municipal manhole construction, through the combined use of the anti-rotation component and the anti-inclination component, when the rotating plate rotates inside the support block, the driving gear at the bottom of the rotating plate meshes with the rectangular toothed plate. Then, when the driving box continues to descend, the rolling wheel drives the driving sprocket to rotate through the third rotating rod, so that the chain drives the fourth rotating rod to rotate through the driven sprocket. The fourth rotating rod drives the rectangular toothed plate to move through the driving gear, so that the sealing plate squeezes and extrudes the inside of the water storage box through movement, and then transports it to the inside of the water distribution box through the connecting pipe, thereby redistributing the weights on both sides inside the driving box, and further avoiding excessive pressure on the first lifting rope due to the inclination of the driving box, thus achieving the effect of preventing excessive pressure.

[0019] Other features and advantages of the present invention will be described in the following specification, and part of them will become obvious from the specification or be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the written specification and the drawings.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the embodiments of the present application, the device or element referred to in the embodiments of the present application or implied must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically specified.

[0024] Specific embodiment 1, please refer to Figures 1 to 5 , an auxiliary hoisting device for municipal pipe well construction, including: a base 1, A fixed seat 12 is fixedly connected to the top of the base 1. A connecting frame 121 is fixedly connected to the top of the fixed seat 12. An adjusting frame 122 is rotatably connected to the top of the connecting frame 121. A counterweight 11 is fixedly connected to the top of the base 1. An adjusting cylinder 123 is fixedly connected to the top of the fixed seat 12. The top of the adjusting cylinder 123 is hinged to the bottom of the adjusting frame 122; The hoisting assembly 2 is arranged on the top of the fixed seat 12 and is used for hoisting materials. The hoisting assembly 2 includes a U-shaped frame 21 fixedly connected to one side of the connecting frame 121. A driving motor 22 is fixedly connected to the surface of the U-shaped frame 21. The output end of the driving motor 22 is fixedly connected to a driving rod 221. A first hoisting rope 222 is arranged on the surface of the driving rod 221. One end of the first hoisting rope 222 is fixedly connected to a driving box 23. Two placement frames 24 are arranged at the bottom of the driving box 23. The hoisting assembly 2 further includes a second hoisting rope 231 and a third hoisting rope 232 arranged inside the driving box 23. The bottoms of the second hoisting rope 231 and the third hoisting rope 232 are respectively fixedly connected to the tops of the two placement frames 24; The tilting assembly 4 is arranged inside the driving box 23 and is used for placing materials in a tilted manner; The anti-rotation assembly 5 is arranged on the top of the driving box 23 and is used to prevent the materials from rotating inside the pipe well, thereby causing damage to the materials; The anti-tilt assembly 6 is arranged inside the driving box 23 and is used to prevent the driving box 23 from tilting, thereby causing unstable support of the first hoisting rope 222; When it is necessary to hoist materials, move the base 1 to a suitable position, then start the adjusting cylinder 123. The adjusting cylinder 123 drives the adjusting frame 122 to rotate on the top of the connecting frame 121, so that the driving box 23 is located in the middle of the pipe well. Then place the materials inside the placement frame 24. Start the driving motor 22. The driving motor 22 drives the first hoisting rope 222 to relax through the driving rod 221, so that the first hoisting rope 222 drives the materials inside the placement frame 24 to be hoisted into the pipe well through the driving box 23; For specific embodiment two, please refer to Figures 1 to 6 According to an auxiliary hoisting device for municipal pipe well construction provided by specific embodiment one, the present embodiment provides a further technical solution: A fixing assembly 3 is arranged inside the two placement frames 24. The fixing assembly 3 includes a threaded hole 31 opened on one side of the two placement frames 24 and a clamping plate 32 slidably connected inside the two placement frames 24. One end of the clamping plate 32 is rotatably connected to a screw rod 321. The screw rod 321 is threadedly connected inside the threaded hole 31. The end of the screw rod 321 away from the clamping plate 32 is fixedly connected to a turning handle 322; When it is necessary to limit the hoisted materials, after the materials are placed inside the placement frame 24, rotate the turning handle 322. The turning handle 322 drives the screw rod 321 to rotate inside the threaded hole 31, so that the screw rod 321 moves towards the inside of the placement frame 24. During the movement of the screw rod 321, the screw rod 321 drives the clamping plate 32 to move, so that the clamping plate 32 limits the hoisted materials, thereby preventing the materials from displacing during hoisting; For specific embodiment three, please refer to Figures 1 to 8, according to an auxiliary hoisting device for municipal pipe well construction provided in the second specific embodiment, the present embodiment provides a further technical solution: The inclination assembly 4 includes a driving motor 41 fixedly connected inside the driving box 23 and a second rotating rod 42 rotatably connected inside the driving box 23. The output end of the driving motor 41 is fixedly connected with a first rotating rod 411. The surface of the first rotating rod 411 is fixedly connected with a driving gear 412. The surface of the second rotating rod 42 is fixedly connected with a driven gear 421. The driving gear 412 and the driven gear 421 are in meshing transmission. The surfaces of the first rotating rod 411 and the second rotating rod 42 are both fixedly connected with storage rollers 43. The tops of the second lifting rope 231 and the third lifting rope 232 are respectively fixedly connected with the surfaces of the two storage rollers 43; When it is necessary to tilt and hoist too long materials, start the driving motor 41. The driving motor 41 drives the driving gear 412 to rotate through the first rotating rod 411, so that the driven gear 421 drives the second rotating rod 42 to rotate. Furthermore, the storage roller 43 drives the second lifting rope 231 to rise and the third lifting rope 232 to fall. The second lifting rope 231 and the third lifting rope 232 respectively drive the corresponding placement frames 24 to rise and fall, so as to tilt the hoisting materials inside the placement frames 24. Then start the driving motor 22. The driving motor 22 drives the first lifting rope 222 to fall through the driving rod 221. Furthermore, the first lifting rope 222 drives the hoisting materials to fall into the pipe well through the driving box 23, so that the too long materials can be hoisted into the pipe well; Specific embodiment four, please refer to Figures 1 to 10 , according to an auxiliary hoisting device for municipal pipe well construction provided in the third specific embodiment, the present embodiment provides a further technical solution: The anti-rotation assembly 5 includes two support blocks 51 fixedly connected to the top of the driving box 23. A rotating plate 511 is rotatably connected between the two support blocks 51. One end of the rotating plate 511 is fixedly connected with a roller frame 52. A third rotating rod 521 is rotatably connected inside the roller frame 52. The surface of the third rotating rod 521 and inside the roller frame 52 is fixedly connected with a rolling wheel 522. The anti-rotation assembly 5 further includes a support plate 53 fixedly connected to the back of the rotating plate 511. The bottom of the support plate 53 is fixedly connected with a spring 531. The bottom of the spring 531 is fixedly connected with the top of the driving box 23; It should be noted that the shape of the rolling wheel 522 can be set according to the edge inside the pipe well, so that the rolling wheel 522 can be in close contact with the inner wall of the pipe well. Therefore, it is not limited here. When the rotating plate 511 is in a horizontal state, the rolling wheel 522 at the bottom of the rotating plate 511 can be in contact with the edge of the pipe well; When it is necessary to prevent the driving box 23 from rotating inside the pipe well, when the first lifting rope 222 drives the driving box 23 to descend, the rolling wheel 522 at the bottom of the rotating plate 511 first contacts the edge at the top of the pipe well. When the driving box 23 continues to descend, the rolling wheel 522 drives the rotating plate 511 to rotate inside the support block 51 through the roller frame 52, so that the rotating plate 511 drives the spring 531 to stretch through the support plate 53. When the rolling wheel 522 contacts the inner wall of the pipe well, the spring 531 is no longer stretched by the support plate 53 and gradually returns to its original state. Furthermore, the rolling wheel 522 is always in contact with the inner wall of the pipe well. Furthermore, when the driving box 23 continues to descend, since the rolling wheel 522 at the top of the driving box 23 is always in contact with the inner wall of the pipe well, the driving box 23 will not drive the hoisting material inside the placement frame 24 to rotate through the second lifting rope 231 and the third lifting rope 232. Furthermore, the hoisting material inside the placement frame 24 will not collide with other objects on the inner wall of the pipe well, thus ensuring the integrity of the hoisting material; Specific Embodiment Five, please refer to Figures 1 to 13 , based on the auxiliary hoisting device for municipal pipe well construction provided in Specific Embodiment Four, the present embodiment provides a further technical solution: The anti-tilting assembly 6 includes a driving sprocket 61 fixedly connected to the surface of the third rotating rod 521 and a support frame 62 fixedly connected to one end of the rotating plate 511. A fourth rotating rod 621 is rotatably connected inside the support frame 62. A driven sprocket 622 is fixedly connected to the surface of the fourth rotating rod 621 and outside the support frame 62. The driving sprocket 61 and the driven sprocket 622 are driven by a chain 611. A driving gear 623 is fixedly connected to the surface of the fourth rotating rod 621 and inside the support frame 62. The anti-tilting assembly 6 further includes a water storage box 63, a water distribution box 632 fixedly connected inside the driving box 23, and a rectangular tooth plate 64 slidably connected inside the driving box 23. The water storage box 63 and the water distribution box 632 are communicated through a communicating pipe 631. Sealing plates 641 are fixedly connected to the opposite surfaces of the rectangular tooth plate 64. The sealing plates 641 are slidably connected inside the water storage box 63 and the water distribution box 632. The rectangular tooth plate 64 is in meshing transmission with the driving gear 623; To avoid the driving box 23 from tilting when hoisting materials obliquely, when the bearing pressure of the first hoisting rope 222 becomes too high, after the rotating plate 511 rotates inside the support block 51, the driving gear 623 at the bottom of the rotating plate 511 meshes with the rectangular toothed plate 64. Then, when the driving box 23 continues to descend, the rolling wheel 522 is in close contact with the inner wall of the pipe well. The rolling wheel 522 drives the driving sprocket 61 to rotate through the third rotating rod 521, so that the chain 611 drives the fourth rotating rod 621 to rotate through the driven sprocket 622. The fourth rotating rod 621 drives the rectangular toothed plate 64 to move through the driving gear 623, so that the sealing plate 641 squeezes out the inside of the water storage box 63 through movement, and then conveys it to the inside of the water distribution box 632 through the connecting pipe 631. Thus, the weights on both sides inside the driving box 23 are redistributed, thereby avoiding excessive pressure on the first hoisting rope 222 caused by the tilt of the driving box 23, prolonging the service life of the first hoisting rope 222, and preventing damage to the first hoisting rope 222; Specific Embodiment Six, the present invention also provides an auxiliary hoisting method for municipal pipe well construction. The auxiliary hoisting method for pipe well construction specifically includes the following steps: Step 1: Place the materials to be hoisted in the two placement frames 24. When the materials are too long, use the tilting assembly 4 to place the materials obliquely; Step 2: Then use the hoisting assembly 2 to hoist the materials into the pipe well. The edge of the pipe well drives the anti-rotation assembly 5, so that the anti-rotation assembly 5 supports the driving box 23, preventing the materials from rotating during the long descent of the materials, and thus avoiding damage to the materials caused by collision; Step 3: During the descent of the driving box 23, the anti-rotation assembly 5 drives the anti-tilt assembly 6 to operate, so that the anti-tilt assembly 6 redistributes the weight inside the driving box 23, thereby preventing damage to the first hoisting rope 222; Step 4: When the placement frame 24 descends to the bottom of the pipe well, use the tilting assembly 4 to restore the materials to the initial state, facilitating the removal of the materials.

[0025] Working principle: When in use, move the base 1 to a suitable position, then start the adjustment cylinder 123. The adjustment cylinder 123 drives the adjustment frame 122 to rotate on the top of the connecting frame 121, so that the driving box 23 is located in the middle of the pipe well. Then place the material inside the placement frame 24. After the material is placed inside the placement frame 24, rotate the turning handle 322. The turning handle 322 drives the screw rod 321 to rotate inside the screw hole 31, so that the screw rod 321 moves towards the inside of the placement frame 24. During the movement of the screw rod 321, the screw rod 321 drives the clamping plate 32 to move, so that the clamping plate 32 limits the hoisted material, thereby preventing the material from shifting during hoisting. Start the driving motor 22. The driving motor 22 drives the first lifting rope 222 to loosen through the driving rod 221, so that the first lifting rope 222 drives the material inside the placement frame 24 through the driving box 23 to be hoisted into the pipe well. When it is necessary to hoist a too long material obliquely, start the driving motor 41. The driving motor 41 drives the driving gear 412 to rotate through the first rotating rod 411, so that the driven gear 421 drives the second rotating rod 42 to rotate, and then the storage roller 43 drives the second lifting rope 231 to rise and the third lifting rope 232 to fall. The second lifting rope 231 and the third lifting rope 232 drive the corresponding placement frames 24 to rise and fall respectively, thereby tilting the hoisted material inside the placement frame 24. Then start the driving motor 22. The driving motor 22 drives the first lifting rope 222 to descend through the driving rod 221, so that the first lifting rope 222 drives the hoisted material to descend into the pipe well through the driving box 23, so that the too long material can be hoisted into the pipe well. When it is necessary to prevent the driving box 23 from rotating inside the pipe well, when the first lifting rope 222 drives the driving box 23 to descend, the rolling wheel 522 at the bottom of the rotating plate 511 first contacts the edge at the top of the pipe well. When the driving box 23 continues to descend, the rolling wheel 522 drives the rotating plate 511 to rotate inside the support block 51 through the roller frame 52, so that the rotating plate 511 drives the spring 531 to stretch through the support plate 53. When the rolling wheel 522 contacts the inner wall of the pipe well, the spring 531 is no longer stretched by the support plate 53 and gradually returns to its original state, so that the rolling wheel 522 always contacts the inner wall of the pipe well. Therefore, when the driving box 23 continues to descend, the driving box 23 will not drive the hoisted material inside the placement frame 24 to rotate through the second lifting rope 231 and the third lifting rope 232, and thus will not cause the hoisted material inside the placement frame 24 to collide with other objects on the inner wall of the pipe well, thereby ensuring the integrity of the hoisted material. To prevent the driving box 23 from tilting when the hoisted material is hoisted obliquely, which may cause the bearing pressure of the first lifting rope 222 to be too high. After the rotating plate 511 rotates inside the support block 51, the driving gear 623 at the bottom of the rotating plate 511 meshes with the rectangular tooth plate 64. Therefore, when the driving box 23 continues to descend, the rolling wheel 522 is in close contact with the inner wall of the pipe well.The rolling wheel 522 drives the driving sprocket 61 to rotate through the third rotating rod 521, causing the chain 611 to drive the fourth rotating rod 621 to rotate through the driven sprocket 622. The fourth rotating rod 621 drives the rectangular toothed plate 64 to move through the driving gear 623, causing the sealing plate 641 to extrude the inside of the water storage box 63 through moving extrusion, and then conveying it to the inside of the water distribution box 632 through the connecting pipe 631, thereby redistributing the weights on both sides inside the driving box 23, and further avoiding excessive pressure on the first lifting rope 222 due to the inclination of the driving box 23, thus extending the service life of the first lifting rope 222 and preventing the first lifting rope 222 from being damaged.
