Description

Technical Field

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

[0002] Municipal pipe wells are an important part of the city's underground pipeline system. They are 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 construction materials need to be transported into the pipe wells, lifting equipment is required to transport the construction materials.

[0003] Publication number CN115465775A discloses a hydraulic lifting device for pipes in pipe wells, comprising a hydraulic support device and a cable. The hydraulic support device comprises a plurality of hydraulic support rods, and the plurality 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 the lifting device of the present invention is used to lift a pipe, the hydraulic support device is sent into the pipe via the cable, and the extension length of the hydraulic support rods is controlled so that the movable ends of all the hydraulic support rods are tightly against the inner wall of the pipe. The friction between the movable ends of the hydraulic support rods and the pipe is utilized to fix the pipe. The lifting work of the pipe can be achieved by retracting and extending the cable, without the need to make lifting ears, which can reduce material and labor waste and reduce damage to the pipe. Moreover, since the extension length of the hydraulic support rods can be adjusted, the lifting device can be suitable for lifting pipes of different diameters and can be used for a long time.

[0004] Although the above-mentioned application and the prior art can lift the pipeline and can adapt to the lifting of different pipe diameters, when the above-mentioned application and the prior art lift an excessively long pipeline, the excessive length of the pipeline will be greater than the diameter of the pipe well, which will result in the pipe well being unable to be quickly lifted into the pipe well. Moreover, when the pipeline is lifted at an angle, the pipeline will rotate inside the pipe well during the process of descending, which will cause the pipeline to collide with the inner wall of the pipe well, thereby causing damage to the pipeline. Moreover, when the pipeline is placed at an angle, the cable at one end will be overloaded during the process of descending, which will cause damage to the cable after long-term use. Therefore, the present invention provides an auxiliary lifting device and method for municipal pipe well construction. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In the embodiments of the present application, any device or element referred to or implied must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise specifically specified.

[0046] For specific embodiment 1, please refer to Figures 1 to 5 , an auxiliary lifting device for municipal pipe well construction, comprising: a base 1,

[0047] The fixed seat 12 is fixedly connected to the top of the base 1. The top of the fixed seat 12 is fixedly connected to the connecting frame 121. The top of the connecting frame 121 is rotatably connected to the adjusting frame 122. The top of the base 1 is fixedly connected to the counterweight 11. The top of the fixed seat 12 is fixedly connected to the adjusting cylinder 123. The top of the adjusting cylinder 123 is hinged to the bottom of the adjusting frame 122.

[0048] A lifting assembly 2 is provided on the top of the fixed seat 12 and is used for lifting materials. The lifting 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 lifting rope 222 is provided on the surface of the driving rod 221. One end of the first lifting rope 222 is fixedly connected to a driving box 23. Two placement frames 24 are provided at the bottom of the driving box 23. The lifting assembly 2 also includes a second lifting rope 231 and a third lifting rope 232 provided inside the driving box 23. The bottoms of the second lifting rope 231 and the third lifting rope 232 are respectively fixedly connected to the tops of the two placement frames 24;

[0049] The tilting assembly 4 is arranged inside the driving box 23 and is used to tilt the material;

[0050] The anti-rotation component 5 is provided on the top of the driving box 23 and is used to prevent the material from rotating inside the pipe well, thereby causing damage to the material;

[0051] The anti-tilt assembly 6 is provided inside the driving box 23 and is used to prevent the driving box 23 from tilting, thereby causing the support of the first suspension rope 222 to be unstable;

[0052] When it is necessary to hoist the material, the base 1 is moved to a suitable position, and then the adjusting cylinder 123 is started. 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 the material is placed inside the placement frame 24, and the driving motor 22 is started. 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 inside of the pipe well;

[0053] For specific embodiment 2, please refer to Figures 1 to 6 According to the auxiliary lifting device for municipal pipe well construction provided in the first embodiment, this embodiment provides a further technical solution:

[0054] A fixing assembly 3 is provided inside the two placement frames 24. The fixing assembly 3 includes a screw hole 31 opened on one side of the two placement frames 24 and a clamping plate 32 slidably connected to the inside of 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 to the inside of the screw hole 31. The end of the screw rod 321 away from the clamping plate 32 is fixedly connected to a handle 322.

[0055] When it is necessary to limit the position of the hoisted material, after the material is placed inside the placement frame 24, the handle 322 is turned, and the handle 322 drives the screw 321 to rotate inside the screw hole 31, so that the screw 321 moves toward the inside of the placement frame 24. During the movement of the screw 321, the screw 321 drives the clamping plate 32 to move, so that the clamping plate 32 limits the hoisted material, thereby preventing the material from being displaced during the hoisting process;

[0056] For specific example three, please refer to Figures 1 to 8 According to the auxiliary lifting device for municipal pipe well construction provided in the second specific embodiment, this embodiment provides a further technical solution:

[0057] The tilting assembly 4 includes a driving motor 41 fixedly connected to the inside of the driving box 23 and a second rotating rod 42 rotatably connected to the inside of the driving box 23. The output end of the driving motor 41 is fixedly connected to the first rotating rod 411. The surface of the first rotating rod 411 is fixedly connected to the driving gear 412. The surface of the second rotating rod 42 is fixedly connected to the driven gear 421. The driving gear 412 and the driven gear 421 are meshed for transmission. The surfaces of the first rotating rod 411 and the second rotating rod 42 are fixedly connected to the storage rollers 43. The tops of the second hanging rope 231 and the third hanging rope 232 are respectively fixedly connected to the surfaces of the two storage rollers 43.

[0058] When it is necessary to tilt and hoist the overlong material, the driving motor 41 is started, and 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, and the second lifting rope 231 and the third lifting rope 232 respectively drive the corresponding placement frame 24 to rise and fall, thereby tilting the hoisting material inside the placement frame 24, and then the driving motor 22 is started, and the driving motor 22 drives the first lifting rope 222 to fall through the driving rod 221, and then the first lifting rope 222 drives the hoisting material to fall into the interior of the pipe well through the driving box 23, so that the overlong material can be hoisted into the interior of the pipe well;

[0059] For specific example 4, please refer to Figures 1 to 10 According to the auxiliary lifting device for municipal pipe well construction provided in the third embodiment, this embodiment provides a further technical solution:

[0060] The anti-rotation assembly 5 comprises two supporting blocks 51 fixedly connected at the top of the driving box 23, a rotating plate 511 rotatably connected between the two supporting blocks 51, one end of the rotating plate 511 fixedly connected with a roller frame 52, a third rotating rod 521 rotatably connected in the roller frame 52, a rolling wheel 522 fixedly connected to the surface of the third rotating rod 521 and located in the roller frame 52, and a supporting plate 53 fixedly connected to the rotating plate 511 and the back, the bottom of the supporting plate 53 fixedly connected with a spring 531, and the bottom of the spring 531 fixedly connected with the top of the driving box 23.

[0061] It should be noted that the shape of the rolling wheel 522 can be set according to the edge of the inside of the pipe well, so that the rolling wheel 522 can be closely fitted with the inner wall of the pipe well, so 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.

[0062] When the driving box 23 needs to be prevented 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 supporting block 51 through the roller frame 52, so that the rotating plate 511 drives the spring 531 to stretch through the supporting plate 53. When the rolling wheel 522 contacts the inner wall of the pipe well, the spring 531 is no longer stretched by the supporting plate 53 and gradually returns to its original state, so that the rolling wheel 522 is always in contact with the inner wall of the pipe well. Therefore, when the driving box 23 continues to descend, the driving box 23 will not drive the lifting material inside the placing frame 24 to rotate through the second lifting rope 231 and the third lifting rope 232, so as to prevent the lifting material inside the placing frame 24 from colliding with other objects on the inner wall of the pipe well, thereby ensuring the integrity of the lifting material.

[0063] Specific embodiment five, please refer to Figures 1 to 13 , according to the auxiliary lifting device for municipal pipe well construction provided in specific embodiment four, the further technical solutions are provided in the embodiment:

[0064] The anti-inclination assembly 6 comprises 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, the inside of the support frame 62 is rotatably connected with a fourth rotating rod 621, the surface of the fourth rotating rod 621 and the outside of the support frame 62 are fixedly connected with a driven sprocket 622, the driving sprocket 61 and the driven sprocket 622 are in transmission through a chain 611, the surface of the fourth rotating rod 621 and the inside of the support frame 62 are fixedly connected with a driving gear 623, the anti-inclination assembly 6 further comprises a water storage box 63 fixedly connected to the inside of the driving box 23, a water distribution box 632 and a rectangular toothed plate 64 slidably connected to the inside of the driving box 23, the water storage box 63 and the water distribution box 632 are communicated through a communication pipe 631, the opposite surfaces of the rectangular toothed plate 64 are fixedly connected with sealing plates 641, the sealing plates 641 are slidably connected to the inside of the water storage box 63 and the water distribution box 632, and the rectangular toothed plate 64 is in meshing transmission with the driving gear 623.

[0065] In order to avoid that the driving box 23 is inclined when the material is hoisted and inclined, and the bearing pressure of the first hoisting rope 222 is too large, when the rotating plate 511 rotates in the inside of the support block 51, the driving gear 623 at the bottom of the rotating plate 511 is in meshing with the rectangular toothed plate 64, and when the driving box 23 continuously descends, 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, 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, the sealing plates 641 extrude the inside of the water storage box 63 through moving and extruding, and then are transported to the inside of the water distribution box 632 through the communication pipe 631, thereby the weight on both sides of the inside of the driving box 23 is redistributed, the pressure of the first hoisting rope 222 is avoided from being too large due to the inclination of the driving box 23, and the service life of the first hoisting rope 222 is prolonged, and the first hoisting rope 222 is avoided from being damaged.

[0066] In the sixth embodiment, the application further provides an auxiliary hoisting method for municipal pipe well construction, which specifically comprises the following steps:

[0067] Step 1: placing the material to be hoisted in the two placing frames 24, and placing the material in an inclined manner through the inclination assembly 4 when the material is too long;

[0068] Step 2: hoisting the material into the pipe well through the hoisting assembly 2, driving the anti-rotation assembly 5 through the edge of the pipe well, supporting the driving box 23 through the anti-rotation assembly 5, and avoiding that the material is rotated and damaged due to the overlength of the material descending;

[0069] Step 3, during the process of the driving box 23 descending, the anti-rotation assembly 5 drives the anti-inclination assembly 6 to work, so that the anti-inclination assembly 6 re-distributes the weight inside the driving box 23, thereby preventing the damage of the first hoisting rope 222;

[0070] Step 4, when the placing frame 24 descends to the bottom of the tube well, the material is restored to the initial state by the inclination assembly 4, thereby facilitating the taking down of the material.

[0071] Working principle: When in use, move the base 1 to a suitable position, and then start the adjusting cylinder 123, and 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, and then the material is placed inside the placement frame 24. After the material is placed inside the placement frame 24, turn the handle 322, and the handle 322 drives the screw 321 to rotate inside the screw hole 31, so that the screw 321 moves toward the inside of the placement frame 24. In the process of moving the screw 321, the screw 321 drives the splint 32 to move, so that the splint 32 limits the hoisting material, thereby preventing the material from being displaced during the hoisting process, and starts the driving motor 22. The driving motor 22 drives the first When the lifting rope 222 is loosened, the first lifting rope 222 drives the material inside the placement frame 24 to be lifted to the inside of the pipe well through the driving box 23. When the overlong material needs to be tilted and lifted, the driving motor 41 is started. 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, thereby causing the storage roller 43 to drive 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 frame 24 to rise and fall, thereby tilting the lifting material inside the placement frame 24. Then the driving motor 22 is started. The driving motor 22 drives the first lifting rope 222 to fall through the driving rod 221, thereby causing the first lifting rope 222 to fall. The driving box 23 drives the hoisting material to descend to the inside of the pipe well, so that the excessively long material can be hoisted into the inside 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 of 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 is always in contact with the inner wall of the pipe well, thereby When the driving box 23 continues to descend, the rolling wheel 522 on the top of the driving box 23 is always in contact with the inner wall of the pipe well. Therefore, the hoisting material inside the placement frame 24 will not be driven to rotate through the second hoisting rope 231 and the third hoisting rope 232, and the hoisting material inside the placement frame 24 will not collide with other objects on the inner wall of the pipe well, thereby ensuring the integrity of the hoisting material. In order to avoid the driving box 23 from tilting when the hoisting material is hoisted at an angle, which will cause the bearing pressure of the first hoisting rope 222 to be too large, when the rotating plate 511 rotates inside the support block 51, the driving gear 623 at the bottom of the rotating plate 511 engages with the rectangular tooth plate 64, and 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 through the third rotating rod 521, the chain 611 drives the fourth rotating rod 621 through the driven sprocket 622, the fourth rotating rod 621 drives the rectangular toothed plate 64 through the driving gear 623, the sealing plate 641 extrudes the water in the water storage box 63 through the movement, and then the water is transported to the inside of the water distribution box 632 through the communication pipe 631, thereby redistributing the weight on both sides of the driving box 23, avoiding the excessive pressure of the first hanging rope 222 due to the inclination of the driving box 23, prolonging the service life of the first hanging rope 222, and avoiding damage to the first hanging rope 222.
