[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0074] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0075] The present application will be described in detail below through examples.

[0076] In existing technologies, municipal sewage pipes often accumulate sludge after severe weather or prolonged lack of maintenance, thus requiring regular dredging. Due to the harsh internal environment of sewage pipes, dredging operations by workers are dangerous and inefficient. While dredging equipment has emerged to replace manual labor, the placement of unblocking buttons in the manholes is inconvenient, affecting dredging efficiency.

[0077] To address the technical problems existing in the prior art dredging equipment, the inventive concept of this application is to provide a non-underground pipeline dredging equipment and dredging system to solve at least one of the technical problems mentioned in the prior art. The non-underground pipeline dredging equipment includes: a main body with a chassis; a working operation unit located at the first end of the main body along its length and mounted on the chassis via a mounting frame for controlling the traction rope; wherein the working operation unit includes a power mechanism, a transmission mechanism, and a control mechanism, the power mechanism transmitting driving force to the control mechanism via the transmission mechanism; the control mechanism includes a first winch and a second winch spaced apart, a first drive shaft at least partially passing through the first winch, a second drive shaft at least partially passing through the second winch, and a winch switching mechanism; the winch switching mechanism includes a first switching part for controlling the rotation or stopping of the first winch, a first transmission part connecting the first drive shaft and the second drive shaft, and a second switching part for controlling the rotation or stopping of the second winch; wherein the first switching part includes a bushing sleeved on the first drive shaft, the bushing having a first position and a second position along the length of the first drive shaft, wherein when it is in the first position, the first winch rotates under the drive of the first drive shaft, and when it is in the second position, the first winch does not rotate with the first drive shaft.

[0078] According to this invention concept, by setting a winch switching mechanism in the working operation section, different winches can be controlled to work according to different scenarios or different processes, thereby using traction ropes with different characteristics, improving the switching efficiency of traction ropes, and facilitating the use of dredging equipment and the operation of personnel.

[0079] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0080] Based on the inventive concept of this application, in some preferred embodiments of this application, the first aspect of this application provides a non-underground pipeline dredging device, referring to... Figures 1-3 ,include:

[0081] The equipment body 10 has a chassis 11.

[0082] The operating unit 20 is located at the first end 101 along the length of the main body 10 and is mounted on the chassis 11 via a mounting bracket 21. It is used to control the release or retrieval of the traction rope. In some embodiments, the mounting bracket 21 is detachably mounted on the chassis 11 to facilitate the transfer and installation of the operating unit 20.

[0083] The operating unit 20 includes a power mechanism 22, a transmission mechanism 23, and a control mechanism 24. The power mechanism 22 transmits driving force to the control mechanism 24 via the transmission mechanism 23. The control mechanism 24 includes a first winch 241 and a second winch 242 spaced apart, a first drive shaft 243 at least partially passing through the first winch 241, a second drive shaft 244 at least partially passing through the second winch 242, and a winch switching mechanism 245. In some specific embodiments, the power mechanism 22 and the transmission mechanism 23 can both adopt structures well known to those skilled in the art. For example, the power mechanism 22 can be a gasoline engine or a diesel engine, and the transmission mechanism 23 includes a drive shaft, gears, etc. (not shown in the figure), which output power to the control mechanism 24.

[0084] In some preferred embodiments, the winch switching mechanism 245 includes a first switching part for controlling the rotation or stop of the first winch, a first transmission part that can simultaneously connect the first drive shaft and the second drive shaft, and a second switching part for controlling the rotation or stop of the second winch; wherein, referring to Figures 5-6 The first switching part includes a bushing 2451 sleeved on the first drive shaft. The bushing 2451 has a first position and a second position in the length direction of the first drive shaft 243. When it is in the first position, the first winch 241 rotates under the drive of the first drive shaft 243. When it is in the second position, the first winch 241 does not rotate with the first drive shaft 243.

[0085] In some embodiments, the first winch 241 in this application is only sleeved on the first drive shaft 243, and the first drive shaft 243 cannot directly drive the first winch 241, while the second winch 242 is fixedly connected to the second drive shaft 244, and the second drive shaft 244 can directly drive the second winch 242.

[0086] By adopting the above technical solution, and by setting up a winch switching mechanism in the working operation section, different winches can be controlled to work according to different scenarios or different processes, thereby using traction ropes with different characteristics, improving the switching efficiency of traction ropes, and facilitating the use of dredging equipment and the operation of personnel.

[0087] In some preferred embodiments, the main body 10 of the device includes casters 30 for moving the device; the chassis 11 is disposed on the upper part of the casters 30. Specifically, there are multiple casters 30, at least one of which is a drive caster to drive the other casters. Further, the main body 10 of the device includes a drive system for driving at least some of the casters, thereby moving the device; the drive system is a gasoline engine drive system, a diesel engine drive system, or an electric motor drive system, etc., as is well known to those skilled in the art.

[0088] In some preferred embodiments, refer to Figures 1-2 The main body 10 of the device further includes a driving operation unit 40, located at the second end 102 in the length direction of the main body 10 of the device, for operating at least some of the moving wheels 30 to control the movement direction of the moving wheels 30, thereby controlling the vehicle body to move to a designated position; the driving operation unit 40 is a steering wheel control system, a handle control system, etc., which are well known to those skilled in the art.

[0089] In some preferred embodiments, refer to Figures 3-7 ( Figures 3-7 (The outer casing of the first winch is not shown). The first switching part has a toggle lever 2452, which can control the movement of the bushing 2451 between a first position and a second position on the first drive shaft 243. The bushing 2451 is fitted onto the first drive shaft 243 and can slide laterally on the first drive shaft 243 under the action of external force. For example, Figure 5 The positional relationship shown in the image indicates that bushing 2451 is in the second position.

[0090] In some preferred embodiments, the first winch 241 has a first mating portion 2411, and the bushing 2451 has a second mating portion 24511. When the bushing 2451 is in a first position, the first mating portion 2411 and the second mating portion 24511 engage. In some embodiments, the first mating portion 2411 has adjacent first protrusions and first recesses, and the second mating portion 24511 has adjacent second protrusions 24512 and second recesses 24513. When the bushing 2451 is in the first position, the first protrusion engages with the second recess 24513, and the second protrusion 24512 engages with the first recess. In some embodiments, the first winch 241 is sleeved on the first drive shaft 243, and the rotation of the first drive shaft 243 does not directly drive the first winch 241 to rotate. Therefore, when the bushing is outside the first position (such as in the second position), the first winch 241 does not rotate with the first drive shaft 243.

[0091] By adopting the above technical solution, through the cooperation between the first mating part and the second mating part, the bushing can drive the first winch to rotate when it is in the first position, thereby realizing the control of the traction rope wound on the winch.

[0092] In some preferred embodiments, the actuating lever 2452 has a fixed end 24521 and a movable end 24522, and a third mating portion 24523 is provided between the fixed end 24521 and the movable end 24522. The bushing 2451 has a fourth mating portion 24514. The third mating portion 24523 and the fourth mating portion 24514 cooperate with each other. Moving the movable end 24522 of the actuating lever 2452 allows the actuating lever 2452 to rotate around the fixed end 24521, thereby driving the bushing 2451 to move. In some embodiments, the third mating portion 24523 is a boss provided on the bottom surface of the actuating lever 2452, and the fourth mating portion 24514 is an annular groove provided circumferentially along the bushing 2451. The bushing cannot rotate relative to the first drive shaft, and the second and fourth mating portions are located on adjacent sides of the bushing. In some embodiments, the fixed end 24521 is rotatably mounted on the mounting bracket 21.

[0093] By adopting the above technical solution, the movable end is moved to make the actuating rod rotate around the fixed end, thereby causing the third mating part to be displaced, realizing indirect control of the third mating part, improving the safety when moving the actuating rod, facilitating the application of force to the third mating part, and simplifying the control of the bushing; furthermore, the bushing is provided with an annular groove around its circumference, so that the third mating part of the actuating rod is always located in the annular groove, eliminating the need to remove the actuating rod after the first drive shaft rotates, thereby simplifying the winch switching process.

[0094] In some embodiments, when the bushing 2451 is in the first position and the second position, the bottom end of the third mating part 24523 and the fourth mating part 24514 do not contact each other, thereby avoiding wear on the actuating rod when the bushing rotates, and also reducing noise during operation.

[0095] In some preferred embodiments, the mounting frame 21 includes a first mounting plate 211, with the first winch 241 and the second winch 242 located on both sides of the first mounting plate 211. Positioning the first winch 241 and the second winch on both sides of the first mounting plate 211 facilitates the differentiation of different winches by workers and also allows for the fixing of the actuating lever, reducing its length and avoiding problems such as easy damage caused by an excessively long lever.

[0096] In some preferred embodiments, a first mounting base 2111 is provided on the upper part of the first mounting plate 211, and the movable end 24522 of the actuating lever 2452 has a fixing rod 24524 set at an angle to the lever body. The first mounting base 2111 includes at least a first mounting groove 21111 and a second mounting groove 21112 for cooperating with the fixing rod 24524 of the actuating lever 2452. When the control sleeve 2451 of the actuating lever 2452 is in the first position, the fixing rod 24524 is located in the first mounting groove 21111; when the control sleeve of the actuating lever is in the second position, the fixing rod 24524 is located in the second mounting groove 21112. In some embodiments, the fixing rod 24524 is substantially perpendicular to the lever body. By adopting the above technical solution, by providing the first mounting groove and the second mounting groove on the boss, it can be used to accommodate the actuating lever on the one hand, and on the other hand, it can fix the actuating lever when the fixing rod is located in the mounting groove, thereby ensuring the stability of the sleeve in the first or second position.

[0097] In some preferred embodiments, refer to Figure 6 The fixing rod 24524 includes a rod body and a rod cap disposed at the upper end of the rod body. The rod body is movably inserted through the actuating rod 2452. When not subjected to external force, the rod cap abuts against the upper end of the actuating rod 2452. For example, when it is necessary to move the bushing from the first position to the second position, the rod cap is pulled, thereby causing the rod body to disengage from the first mounting groove 21111. The actuating rod 2452 is moved to move the fixing rod 24524 to the second mounting groove 21112, and the rod cap is released, allowing the rod body to fall into the second mounting groove 21112, thus achieving fixation. This solution allows for more flexible fixing and movement of the actuating rod, facilitating operation by staff.

[0098] In some embodiments, reference Figure 11(For ease of reference, the second winch and other structures are omitted in the figure.) The chassis 11 and the mounting frame 21 are provided with a cable routing gap 210 near the first end 101 to facilitate the lead-out of the first traction rope connected to the first winch 241. Preferably, the cable routing gap 210 is provided on the first mounting plate 211.

[0099] In some preferred embodiments, reference Figure 7 The first transmission part includes a first sleeve ring 2453 sleeved on the first drive shaft 243, a second sleeve ring 2454 sleeved on the second drive shaft 244, and a first transmission assembly. Under the transmission of the first transmission assembly, the first sleeve ring 2453 and the second sleeve ring 2454 rotate synchronously. In some embodiments, the first sleeve ring 2453 and the second sleeve ring 2454 are driven by a first transmission chain 2455.

[0100] In some preferred embodiments, the second switching part includes a pin 2456, and the second sleeve 2454 and the second drive shaft 244 respectively have a first connecting hole and a second connecting hole. When the pin is simultaneously at least partially inserted into the first connecting hole and the second connecting hole, the second drive shaft 244 rotates under the drive of the first transmission part. In normal operation, when the bushing 2451 is in the second position, the first winch 241 does not rotate with the shaft. At this time, the pin 2456 is inserted to drive the second winch 242, realizing the switching between the first winch 241 and the second winch 242. However, this application does not limit the situation where the first winch 241 and the second winch 242 work simultaneously.

[0101] In some preferred embodiments, the first winch 241 and the second winch 242 are respectively fitted with a first traction rope and a second traction rope, the first traction rope and the second traction rope being made of different materials and / or having different load-bearing limits. Using the above scheme, the traction rope can be changed by switching between the first winch and the second winch, thereby using a suitable traction rope according to different working conditions or workflows. In some embodiments, before the underground dredging begins, the first dredging equipment needs to release the second traction rope via the second winch and transport it to the bottom of the well to the second dredging equipment. After connecting the third traction rope released by the second dredging equipment (equivalent to the first traction rope of the first dredging equipment), the first traction rope is pulled back to the first dredging equipment, replaced with the first traction rope at the first dredging equipment, and a dredging button is connected between the first traction rope and the third traction rope, and then placed underground for dredging work.

[0102] In some preferred embodiments, a positioning rod is provided on the mounting bracket 21 near the first end 101 to control the height of the first end 101 of the vehicle body, and at the same time to keep the vehicle body stable and achieve a stable dredging process.

[0103] In some preferred embodiments, reference Figure 8 The non-underground pipeline dredging equipment further includes an installation rail 50, which is mounted on the mounting frame 21. The power mechanism 22 is fixed to the support frame 60 and is movably mounted on the installation rail 50 via the support frame 60. In some embodiments, the installation rail 50 is arranged along the length of the equipment body 10 and includes a first track and a second track arranged in parallel. At least one of the first track and the second track has an adjustment hole 51 on its upper surface. The support frame 60 is arranged perpendicular to the installation rail 50 and includes a first frame and a second frame arranged in parallel. At least one of the first frame and the second frame is fixed to the installation rail through the adjustment hole. The adjustment hole is a strip-shaped hole, and / or the adjustment hole includes multiple circular holes.

[0104] In practical work, it may be necessary to move the entire mounting frame onto the chassis of other equipment. Since the power mechanism is heavy, the center of gravity of other equipment is prone to drastic changes after the mounting frame is configured, resulting in unstable movement. This solution, by setting adjustment holes on the mounting rail, allows the position of the power mechanism to be adjusted along the length of the main body of the equipment, thereby adjusting the vehicle's center of gravity and improving the versatility and safety of the equipment.

[0105] In some preferred embodiments, reference Figure 10 The non-underground pipeline dredging equipment also includes a protective frame 70, which comprises: a third frame 71 and a fourth frame 72 for installation at the wellhead. One end of the third frame 71 is connected to the chassis, and the other end is connected to the end of the fourth frame 72 away from the chassis. The third frame 71 and the fourth frame 72 are arranged at an angle. The fourth frame 72 is provided with a pulley 721, which is located at the end near the chassis and is used to transport the first traction rope and / or the second traction rope at the position away from the bottom surface.

[0106] By adopting the above technical solution, pulleys are installed at the wellhead through the third and fourth frames. The traction rope can be transported through the pulleys, which reduces the wear of the traction rope on the wellhead, improves work safety, and reduces damage to municipal facilities.

[0107] In some preferred embodiments, the third frame 71 includes a first rod 711 having a first mounting position and a second mounting position along its length. The first rod 711 is detachably connected to the chassis 11 via the first mounting position and the second mounting position. Specifically, refer to... Figure 12The first rod 712 can be detachably fixed to the chassis 11 by engaging with mounting hooks 111 spaced apart on the chassis 11. One end of the second rod 712 is fixedly connected to the first rod near the first mounting position 7111, and the other end is fixedly connected to the fourth frame 72. One end of the third rod 713 is fixedly connected to the first rod near the second mounting position 7112, and the other end is fixedly connected to the fourth frame 72. In some embodiments, the distance between the second rod 712 and the third rod 713 gradually decreases in the direction away from the chassis. In some embodiments, the second rod 712 and the third rod 713 are both located inside the first and second mounting positions to facilitate the installation of the third frame 71 and reduce the movement space of the third frame 71 relative to the chassis 11, thereby maintaining stability.

[0108] By adopting the above technical solution, a third frame is formed by setting up a first rod, a second rod, and a third rod. This ensures the stability of the third frame and facilitates its installation and disassembly, thereby improving work efficiency. Furthermore, the third frame 71 is connected to the chassis rather than to the mounting frame 21. This avoids interference with the mechanical structures on the mounting frame 21 and reduces the impact of vibrations from the mounting frame 21 on the protective frame 70.

[0109] In some preferred embodiments, reference Figure 9 The working operation unit 20 also includes a water receiving tray 25, which is located below the first winch 241 and is used to collect sewage dripping from the first traction rope. In some embodiments, the water receiving tray 25 is fixedly installed at the lower end of the base 11, and the entire projection of the first winch 241 falls into the water receiving tray 25. Since the first traction rope inevitably carries sewage after operation, the above technical solution facilitates the collection of sewage dripping from the first traction rope, ensuring the cleanliness of the work site; and by placing the water receiving tray 25 at the lower end of the base 11, it can be prevented from affecting the movement of the first traction rope.

[0110] In other embodiments of this application, a dredging system is provided, with reference to... Figure 13 As shown, it includes:

[0111] The first non-underground pipeline dredging device 100 and the second non-underground pipeline dredging device 200 are arranged at intervals, and both the first non-underground pipeline dredging device 100 and the second non-underground pipeline dredging device 200 are as described in the above embodiments of this application.

[0112] The unblocking button 300 is located between the first non-underground pipeline dredging device 100 and the second non-underground pipeline dredging device 200, and the first traction rope 400 or the second traction rope is connected to both ends of the unblocking button 300 and respectively connected to the first non-underground pipeline dredging device 100 and the second non-underground pipeline dredging device 200.

[0113] By adopting the above technical solution, two dredging devices proposed in this application are set up and work together to achieve non-manhole dredging of municipal sewage pipelines, which improves work efficiency while ensuring the safety of staff.

[0114] In summary, the non-underground pipeline dredging equipment and dredging system provided by the embodiments of the present invention, by setting a winch switching mechanism in the working operation section, can control the operation of different winches according to different scenarios or different processes, thereby using traction ropes with different characteristics, solving the technical problems mentioned in the background art, improving the efficiency of traction rope switching, and facilitating the use of dredging equipment and the operation of personnel.

[0115] It should be noted that, for those skilled in the art, the technical features in the above embodiments can be freely combined, and the resulting technical solutions also belong to the embodiments disclosed in this application.

[0116] Furthermore, without departing from the principles of this application, several improvements and modifications may be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
