Description

Technical Field

[0001] This utility model relates to the field of underground pipeline dredging technology, specifically to an underground pipeline dredging device. Background Technology

[0002] In underground pipeline dredging operations, different equipment combinations are usually selected according to the type of pipeline, the degree of blockage, and the working environment. Common equipment includes high-pressure cleaners / trucks, vacuum trucks, spring dredging machines, cable dredging machines, push rod dredging machines, CCTV pipeline inspection robots, pneumatic dredging equipment, and chemical dredging equipment.

[0003] High-pressure flushing nozzles, also known as water rats, pipe-specific nozzles, pipe dredging nozzles, pipe flushing heads, etc., are the most important part of high-pressure cleaning machines / vehicles. They mainly use high-pressure pumps and pipes to supply water, and then the nozzles at the tail or head of the nozzles spray high-pressure water to flush the inside of the pipes, loosening and washing away silt and other impurities, thereby achieving the effect of pipe cleaning.

[0004] Existing high-pressure flushing nozzles are typically made of tungsten carbide, ceramic, or stainless steel. Tungsten carbide is mainly used to withstand the impact of high-pressure water flow at the nozzle, while stainless steel is mainly used as the nozzle shell. However, the nozzle needs to move inside the pipeline to increase the area for flushing the pipeline. When the nozzle moves, it needs to come into contact with the inner wall of the pipeline and silt, which causes the nozzle to wear out easily and requires frequent replacement. Moreover, the nozzle has internal structures such as water channels and tungsten carbide nozzles, making replacement cost relatively high. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an underground pipeline dredging device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an underground pipeline dredging device, comprising a main body, with supports connected to the lower sides of both sides of the main body, and limiting plates connected to the bottom of the two supports. Multiple insertion holes are opened on one side of the top of the two limiting plates, and multiple bolts are passed through one side of the top of the two supports. Each bolt is connected to a pin at one end, and two support rods are respectively connected between the multiple pins and the two limiting plates. Each support rod has a slot inside.

[0007] By adopting the above technical solution, the height of the main body of the equipment is raised by the bracket and support rod, avoiding contact between the bottom of the main body of the equipment and the inner wall of the pipe, thereby reducing the wear of the main body of the equipment. The support rod replaces the main body of the equipment in bearing the wear between the equipment and the underground pipe and most of the flowing sludge. The bracket can also support the main body of the equipment in conjunction with the support rod, reducing the phenomenon of the main body of the equipment rolling and twisting the pipe during the flushing process. The slot is X-shaped, so when one side of the support rod is worn, the worker can remove the bolt to remove the pin from the socket, thereby releasing the limitation on the support rod. Then the worker can remove the support rod along the track of the limiting plate. After that, the worker rotates the support rod 90 degrees and puts it back on the limiting plate. After the support rod is put back, the worker tightens the bolt so that the pin passes through the slot and the socket. The pin and the limiting plate lock the slot, thereby preventing the support rod from falling off. At the same time, the inner wall of the bracket can help limit the support rod, distribute stress, and prevent the support rod from horizontal displacement, thereby reducing the impact force on the pin and the limiting plate. If all four sides of the support rod are worn, the worker can replace it with a new support rod.

[0008] Furthermore, the slot is X-shaped.

[0009] By adopting the above technical solution, the slot is X-shaped. Therefore, after one side of the support rod is worn, the worker can rotate the support rod 90 degrees and put it back on the limit plate. If all four sides of the support rod are worn, the worker can replace it with a new support rod, which greatly extends the service life of the support rod.

[0010] Furthermore, both the limiting plate and the pin are inclined, and the inclination angle of both the limiting plate and the pin is 45°. The limiting plate and the pin are distributed perpendicularly.

[0011] By adopting the above technical solution, the vertical distribution of the limiting plate and the pin can be adapted to the X-shaped slot, thereby facilitating entry into the slot to limit the support rod and prevent the support rod from falling off.

[0012] Furthermore, the lengths of both the limiting plate and the pin are less than the length of the slot.

[0013] By adopting the above technical solution, the shorter length of the limiting plate and the pin reduces the occurrence of wear caused by the limiting plate and the pin contacting the underground pipe wall after the support rod wears down.

[0014] Furthermore, the support rod is detachably connected to the bracket via a limiting plate, a pin, and a socket.

[0015] By adopting the above technical solution, the staff can remove the bolts to move the pin out of the socket, thereby releasing the limit on the support rod. Then the staff can remove the support rod along the track of the limit plate.

[0016] Furthermore, the pin is detachably connected to the socket, and the bolt is threadedly connected to the bracket.

[0017] By adopting the above technical solution, workers can remove the bolt to move the pin out of the socket, and conversely, workers can screw the bolt back to make the pin pass through the slot and the socket.

[0018] Furthermore, the bolts, pins, and holes are divided into two groups, and the two groups of bolts, pins, and holes, as well as the two brackets, limiting plates, support rods, and slots, are all mirror-distributed.

[0019] By adopting the above technical solution, two brackets and support rods are distributed on the left and right sides of the main body of the equipment to support the main body of the equipment and reduce the phenomenon of the main body of the equipment rolling and twisting the pipes during the flushing process.

[0020] Furthermore, a connector is fixed in the middle of the outer surface of the main body of the device, and a water inlet is opened at one end of the connector. Multiple nozzles are provided on the outer surface of the main body of the device, and the multiple nozzles are distributed in a ring array.

[0021] By adopting the above technical solution, the main body of the equipment is connected to an external pipeline through a connector, and the external pipeline is connected to an external high-pressure washing vehicle or high-pressure washing machine. Then, the staff can send the main body of the equipment and the pipeline into the underground pipe. During this process, the high-pressure washing vehicle or high-pressure washing machine delivers high-pressure water to the main body of the equipment through the pipeline. The high-pressure water enters the main body of the equipment from the inlet and then sprays out from the nozzle. At this time, the staff pushes the pipeline to move the main body of the equipment in the underground pipe. During this process, the high-pressure water sprayed from the nozzle washes away the silt in the underground pipe.

[0022] Furthermore, both the main body of the equipment and the support rod are made of 304 stainless steel, and the surfaces of both the main body and the support rod are coated with a thermally sprayed tungsten carbide coating with a thickness of 0.3 to 0.5 mm.

[0023] By adopting the above technical solution, the thermally sprayed tungsten carbide coating has high hardness and therefore good wear resistance. The dense coating has strong impact resistance and is not easy to peel off. The cost is lower than that of using tungsten carbide throughout the entire coating.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the setting of a bracket and support rod, raises the height of the main body of the equipment by cooperating with the bracket and support rod, avoiding contact between the bottom of the main body of the equipment and the inner wall of the pipe, thereby reducing the wear of the main body of the equipment. The support rod replaces the main body of the equipment in bearing the wear between the equipment and the underground pipe and most of the flowing sludge. Compared with replacing the main body of the equipment, the support rod is simpler to manufacture and has a lower replacement cost. Moreover, the bracket can cooperate with the support rod to support the main body of the equipment, reducing the phenomenon of the main body of the equipment rolling and twisting the pipe during the flushing process. The lower cost structure replaces the main body of the equipment in bearing the wear, thereby reducing the replacement cost.

[0026] 2. This utility model, through the arrangement of a bracket, limiting plate, bolts, pins, insertion holes, and slots, with the slots being X-shaped, allows the bolts to be removed after one side of the support rod is worn, enabling the pins to move out of the insertion holes and thus releasing the limitation on the support rod. The support rod can then be removed along the track of the limiting plate. Afterward, the support rod can be rotated 90 degrees and reinstalled on the limiting plate. Once reinstalled, the bolts are tightened to allow the pins to pass through the slots and insertion holes. The pins, in conjunction with the limiting plate, lock the slots, preventing the support rod from falling off. Simultaneously, the inner wall of the bracket assists in limiting the support rod, dispersing stress, and preventing horizontal displacement of the support rod, thereby reducing the impact force on the pins and limiting plate. If all four sides of the support rod are worn, a new support rod can be replaced. This facilitates the replacement of the support rod, and the support rod can be used four times, extending its service life. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] An underground pipeline dredging device, such as Figures 1-5 As shown, the device includes a main body 1, with brackets 5 connected to the lower sides of both sides. Limiting plates 6 are connected to the bottom of the two brackets 5. Multiple insertion holes 9 are opened on one side of the top of each of the two limiting plates 6. Multiple bolts 7 pass through the top of each of the two brackets 5, and the bolts 7 are threaded to the brackets 5. A pin 8 is connected to one end of each bolt 7. The pin 8 is detachably connected to the insertion hole 9. Both the limiting plates 6 and the pins 8 are inclined at an angle of 45°. The limiting plates 6 and the pins 8 are perpendicularly distributed. The pins 8 are connected to the two limiting plates 6 respectively. Two support rods 10 are connected to the bracket 5 via a limiting plate 6, a pin 8, and a socket 9. Each support rod 10 has an internal slot 11 in an "X" shape. The lengths of the limiting plate 6 and the pin 8 are shorter than the lengths of the slots 11. Multiple bolts 7, pins 8, and sockets 9 are divided into two groups. These bolts 7, pins 8, and sockets 9, along with the two brackets 5, the limiting plate 6, the support rods 10, and the slots 11, are mirror-distributed. The bracket 5, in conjunction with the support rods 10, raises the height of the main body 1 of the equipment, preventing the bottom of the main body 1 from contacting the pipe. The inner wall of the pipe is in contact with the support rod 10, which reduces wear on the main body of the equipment 1. The support rod 10 replaces the main body of the equipment 1 in bearing the wear between the main body of the equipment and the underground pipe and most of the flowing mud and sand. The bracket 5 can cooperate with the support rod 10 to support the main body of the equipment 1, reducing the phenomenon of the main body of the equipment 1 rolling and twisting the pipe during the flushing process. The slot 11 is X-shaped, so after one side of the support rod 10 is worn, the operator can remove the bolt 7 to remove the pin 8 from the socket 9, thereby releasing the limitation on the support rod 10. Then the operator can move the support rod 10 along the trajectory of the limiting plate 6. After removing the support rod 10, the worker rotates it 90 degrees and reinstalls it onto the limiting plate 6. After reinstalling the support rod 10, the worker tightens the bolt 7 so that the pin 8 passes through the slot 11 and the hole 9. The pin 8 cooperates with the limiting plate 6 to lock the slot 11, thereby preventing the support rod 10 from falling off. At the same time, the inner wall of the bracket 5 can help limit the support rod 10, distribute stress, and prevent the support rod 10 from horizontally displacing, thereby reducing the impact force on the pin 8 and the limiting plate 6. If all four sides of the support rod 10 are worn, the worker can replace it with a new support rod 10.

[0037] See Figure 1In the above embodiment, a connector 2 is fixed in the middle of the outer surface of the main body 1. A water inlet 3 is opened at one end of the connector 2. Multiple nozzles 4 are provided on the outer surface of the main body 1. The multiple nozzles 4 are distributed in a ring array. The main body 1 is connected to an external pipe through the connector 2. The external pipe is connected to an external high-pressure washing vehicle or high-pressure washing machine. Then, the staff can send the main body 1 and the pipe into the underground pipe. During this period, the high-pressure washing vehicle or high-pressure washing machine delivers high-pressure water to the main body 1 through the pipe. The high-pressure water enters the main body 1 from the water inlet 3 and then sprays out from the nozzles 4. At this time, the staff pushes the pipe to move the main body 1 in the underground pipe. During this period, the high-pressure water sprayed from the nozzles washes away the silt in the underground pipe.

[0038] Example 2:

[0039] Based on the above embodiment 1, in order to increase the wear resistance of the main body 1 and the support rod 10, the following settings are now implemented.

[0040] See Figure 1 , Figure 2 , Figure 4 and Figure 5 In the above embodiments, the main body 1, bracket 5, bolt 7, pin 8 and support rod 10 are all made of 304 stainless steel. The surface of the main body 1, the surface of the bracket 5, one end of the bolt 7 and the surface of the support rod 10 are all provided with a thermally sprayed tungsten carbide coating. The thickness of the coating is 0.3 to 0.5 mm. The thermally sprayed tungsten carbide coating has high hardness and therefore good wear resistance. The dense coating has strong impact resistance and is not easy to peel off. The cost is lower than that of using tungsten carbide throughout.

[0041] The implementation principle of this utility model is as follows: First, the main body of the equipment 1 is connected to an external pipe through the connector 2, and the external pipe is connected to an external high-pressure washing vehicle or high-pressure washing machine. Then, the staff can send the main body of the equipment 1 and the pipe into the underground pipe. During this period, the high-pressure washing vehicle or high-pressure washing machine delivers high-pressure water to the main body of the equipment 1 through the pipe. The high-pressure water enters the main body of the equipment 1 from the inlet 3 and then sprays out from the nozzle 4. At this time, the staff pushes the pipe to move the main body of the equipment 1 in the underground pipe. During this period, the high-pressure water sprayed from the nozzle washes away the silt in the underground pipe.

[0042] The height of the main body of the equipment is raised by the bracket 5 and the support rod 10 to avoid the bottom of the main body of the equipment 1 from contacting the inner wall of the pipe, thereby reducing the wear of the main body of the equipment 1. The support rod 10 replaces the main body of the equipment 1 in bearing the wear between the equipment 1 and the underground pipe and most of the flowing mud and sand. The bracket 5 can also work with the support rod 10 to support the main body of the equipment 1, reducing the phenomenon of the main body of the equipment 1 rolling and twisting the pipe during the flushing process.

[0043] The slot 11 is X-shaped, so after one side of the support rod 10 is worn, the operator can remove the bolt 7 to move the pin 8 out of the socket 9, thereby releasing the restriction on the support rod 10. Then, the operator can remove the support rod 10 along the track of the limiting plate 6. Afterwards, the operator rotates the support rod 10 ninety degrees and reinstalls it on the limiting plate 6. After reinstalling the support rod 10, the operator tightens the bolt 7 so that the pin 8 passes through the slot 11 and the socket 9. The pin 8, in conjunction with the limiting plate 6, locks the slot 11 in place. To prevent the support rod 10 from falling off, the inner wall of the bracket 5 can help limit the support rod 10, disperse stress, and prevent the support rod 10 from horizontally displacing, thereby reducing the impact force on the pin 8 and the limiting plate 6. If all four sides of the support rod 10 are worn, the staff can replace it with a new support rod 10. To prevent the bolt 7 from loosening due to vibration, the stability of the bolt 7 can be increased by using components such as washers, or a detachable anti-loosening bolt can be used as a substitute. Then, the pin 8 is fixed to the bottom of the anti-loosening bolt by welding.
