Description

Technical Field

[0001] This utility model relates to the field of dredging device technology, and in particular to a walking structure for a sewage pipe dredging device. Background Technology

[0002] Urban underground drainage systems play a vital role in preventing urban flooding and ensuring sewage discharge; therefore, their capacity and reliability directly impact the level of urban infrastructure. However, many branch drainage systems have pipe diameters of only 300–800 mm. When cleaning sediment and silt from these pipes, manual operation is impossible, so dredging equipment is typically used.

[0003] Existing dredging devices mostly adopt a wheeled walking design. However, because the inner wall of the sewage pipe is often slippery and covered with a lot of impurities and dirt, the dredging device is prone to slipping or encountering obstacles and being unable to move during the process, which significantly reduces work efficiency and affects the cleaning effect and operation progress.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] Please see Figure 1-9 This utility model provides a walking structure for a sewage pipe dredging device, including a cylindrical body 1. The cylindrical body 1 includes a front cover 11, a rear cover 12, and four sets of annular array connecting beams 13. The front cover 11 and the rear cover 12 are respectively fixedly connected to the left and right sides of the four sets of connecting beams 13. A reduction motor 2 is fixedly connected to the right side of the cylindrical body 1 via a bracket. The output shaft of the reduction motor 2 is fixedly connected to multiple sets of dredging scrapers 21. A sludge pump 3 is fixedly connected to the lower end of the cylindrical body 1 via a bracket. A connecting pipe 31 is fixedly connected to the right side of the sludge pump 3, and a connecting pipe 31 is fixedly connected to the left side of the sludge pump 3. A connecting pipe 32 is connected to the cylindrical body 1. A fixed ring seat 4 is fixedly connected to the left side inside the cylindrical body 1. A hydraulic rod 5 is fixedly connected to the right side of the fixed ring seat 4. A movable ring seat 6 is fixedly connected to the telescopic end of the hydraulic rod 5. The movable ring seat 6 is slidably connected to the right side inside the cylindrical body 1. Multiple sets of movable holes 66 are equally spaced through the outer sides of both the fixed ring seat 4 and the movable ring seat 6, and the multiple sets of movable holes 66 are arranged in a ring array. A support leg 7 is movably connected inside the movable hole 66. An adjustment component 8 for adjusting the length of the support leg 7 is connected inside both the fixed ring seat 4 and the movable ring seat 6.

[0030] This invention, through the cooperation of the adjusting component 8 and the supporting leg 7, can tightly fit the supporting leg 7 against the inner wall of the sewage pipe, making it suitable for sewage pipes of different diameters. Furthermore, through the cooperation of the fixed ring seat 4, the hydraulic rod 5, and the movable ring seat 6, the cylindrical body 1 can drive the sludge removal device to move within the sewage pipe, effectively reducing the occurrence of slippage or obstruction by dirt during the movement of the sludge removal device.

[0031] Specifically, firstly, the fixed ring seat 4 adjusts the length of the supporting leg 7 through its internal adjusting component 8, ensuring that the supporting leg 7 of the fixed ring seat 4 is in full and tight contact with the inner wall of the sewage pipe. At this time, the cylindrical body 1 is firmly fixed to the inner wall of the sewage pipe by the fixed ring seat 4, ensuring that the sludge removal device is not easily displaced. Next, the reduction motor 2 drives the sludge scraper 21 through its output shaft to remove sludge. At the same time, the sludge pump 3 operates, extracting the sludge in the sewage pipe through connecting pipe 1 31 and connecting pipe 2 32. After the cleaning of a local area is completed, the cylindrical body 1 is controlled to move. The cylindrical body 1 moves as follows: the extension end of the hydraulic rod 5 is extended, and the extension end drives the movable ring seat 6 to move to the right. At this time, the movable ring seat 6 slides relative to the cylindrical body 1. After the extension end of the hydraulic rod 5 extends a certain length, the length of the supporting leg 7 is adjusted by the adjusting component 8 inside the movable ring seat 6, ensuring that the supporting leg 7 of the movable ring seat 6 is in full and tight contact with the inner wall of the sewage pipe. At this time, the movable ring seat 6 is relatively fixed to the sewage pipe. Next, the length of the support leg 7 is adjusted by the adjusting component 8 inside the fixed ring seat 4, so that the support leg 7 belonging to the fixed ring seat 4 is disengaged from the inner wall of the sewage pipe. Then, the telescopic end of the hydraulic rod 5 is retracted, thereby driving the fixed ring seat 4 and the cylindrical body 1 to move to the right, thus completing the walking process of the cylindrical body 1.

[0032] Furthermore, four sets of L-shaped brackets 61 in a ring array are welded to the right side of the movable ring seat 6. The ends of the four sets of L-shaped brackets 61 away from the movable ring seat 6 are connected to a central disk 62. Four sets of L-shaped brackets 63 in a ring array are welded to the left side of the movable ring seat 6. The ends of the four sets of L-shaped brackets 63 away from the movable ring seat 6 are connected to a central disk 64. A fixing frame 65 is fixedly connected to the left side of the L-shaped brackets 63.

[0033] Specifically, the fixed ring seat 4 and the movable ring seat 6 have the same structure, which will not be described again in this article. The hydraulic rod 5 connects the fixed ring seat 4 and the movable ring seat 6. Specifically, the base 73 of the hydraulic rod 5 is fixedly connected to the right side of the central disk 62 of the fixed ring seat 4, and the telescopic end of the hydraulic rod 5 is fixedly connected to the left side of the fixed frame 65 of the movable ring seat 6.

[0034] Furthermore, a groove 131 is provided on the inner side of the connecting beam 13, and four sets of sliders 67 that cooperate with the groove 131 are fixedly connected to the outer side of the movable ring seat 6.

[0035] Specifically, when the movable ring seat 6 slides relative to the connecting beam 13, the slider 67 on the outer side of the movable ring seat 6 slides within the slide groove 131. The slide groove 131 restricts the sliding edge of the slider 67, serving as a guide and limiter.

[0036] Furthermore, the support leg 7 includes a sleeve 71 and a movable rod 74. The sleeve 71 is slidably connected inside the movable hole 66. A spring 72 is fixedly connected inside the sleeve 71. A base 73 is fixedly connected to the upper end of the spring 72. The movable rod 74 is fixedly connected to the side of the base 73 away from the spring 72, and the movable rod 74 is slidably connected to the inside of the opening of the sleeve 71. A top block 75 that fits against the inner wall of the sewage pipe is fixedly connected to the end of the movable rod 74 away from the base 73. An annular seat 76 is fixedly connected inside the sleeve 71 and inside the spring 72. A sensor 77 is fixedly connected inside the annular seat 76. The sensor 77 is electrically connected to the control terminal. The sensor 77 will only receive a signal when the base 73 abuts against the upper surface of the annular seat 76.

[0037] Specifically, through the setting of sensor 77, when the support leg 7 is adjusted to the correct position, sensor 77 transmits a signal to the control terminal. The control terminal then controls the adjustment component 8 to stop operating, thereby ensuring the accuracy of the length adjustment of the support leg 7 and making it suitable for sewage pipes of different diameters. Specifically, when the adjustment component 8 adjusts the length of the support leg 7, the top block 75 first contacts the sewage pipe. As the adjustment component 8 continues to adjust, the base 73 and the sleeve 71 slide relative to each other. During this process, the spring 72 is compressed until the base 73 abuts against the annular seat 76. At this time, sensor 77 receives a signal and transmits the signal to the control terminal. Preferably, sensor 77 is a contact sensor. When the base 73 abuts against the upper surface of the annular seat 76, the base 73 will contact the contact sensor, thereby ensuring timely signal transmission.

[0038] Furthermore, guide grooves 661 are symmetrically provided on both sides of the movable hole 66, and guide pins 711 that slide in cooperation with the guide grooves 661 are symmetrically fixedly connected on both sides of the sleeve 71.

[0039] Specifically, when the sleeve 71 slides relative to the movable hole 66, it drives the guide pin 711 to slide in the guide groove 661. The guide groove 661 guides and limits the guide pin 711, ensuring that the sleeve 71 always slides along the diameter of the movable hole 66.

[0040] Furthermore, multiple sets of protrusions 751 are fixedly connected to the side of the top block 75 away from the movable rod 74.

[0041] Specifically, these protrusions 751 enhance the contact force between the top block 75 and the drain pipe. More specifically, these protrusions 751 effectively increase the contact area between the top block 75 and the inner wall of the drain pipe, thereby improving the contact force. When the top block 75 abuts against the inner wall of the drain pipe, the friction generated between the protrusions 751 and the drain pipe not only increases contact stability but also ensures that the relative position between the top block 75 and the drain pipe remains fixed. This effectively prevents the top block 75 from sliding due to other external forces during operation.

[0042] Furthermore, the adjustment component 8 includes a servo motor 81 and a threaded rod 82. The servo motor 81 is fixedly connected to the inner side of the fixed frame 65 and is electrically connected to the control terminal. The threaded rod 82 is fixedly connected to the output shaft end of the servo motor 81. The end of the threaded rod 82 away from the servo motor 81 passes through the second central disk 64 and is rotatably connected to the left side of the first central disk 62. The outer side of the threaded rod 82 is threaded with an inner conical pedestal 83. The sleeve 71 is slidably connected to the inner conical pedestal 83. The side of the sleeve 71 away from the top block 75 is provided with a slope that matches the outer wall of the inner conical pedestal 83.

[0043] Specifically, the servo motor 81 is controlled by the control terminal. The servo motor 81 drives the threaded rod 82 to rotate through the output shaft, thereby moving the hollow conical platform 83. When the hollow conical platform 83 moves from left to right, its diameter gradually increases, thereby moving the sleeve 71, which is slidably connected to its outer wall, to the outside, thus achieving the purpose of adjusting the length of the support leg 7.

[0044] Furthermore, a pulley 78 is rotatably connected to the side of the sleeve 71 away from the top block 75, and multiple sets of limiting grooves 831 are provided on the front side of the hollow conical platform 83 to slide in cooperation with the pulley 78.

[0045] Specifically, the hollow conical platform 83 and the sleeve 71 are connected by a pulley 78. When the hollow conical platform 83 moves, the pulley 78 slides inside the limiting groove 831, thereby making the sleeve 71 slide more smoothly.

[0046] It should be noted that all electrical devices mentioned above are electrically connected to the control terminal.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
