Description

Technical Field

[0001] The invention relates to the technical field of pipeline backfilling, and in particular to a pipeline backfilling device for underground water pipes. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The circulating water pipe system of a power plant is an indispensable part of the operation of the power plant. Its main function is to serve as a cooling system to maintain the normal operation of the power plant. The pre-buried water pipe usually digs a trench on the ground first, then installs the water pipe into the trench, and backfills the soil after the installation is completed. The backfilling step is usually used when the pipeline is initially installed, or after the pipeline is dug and buried for maintenance. The existing backfilling method generally uses an excavator, a bulldozer, and an earthmoving vehicle to cooperate with each other to backfill. Specifically, the soil generated by digging the trench is first transferred to the earthmoving vehicle by the excavator, and then the soil is poured into the trench by the earthmoving vehicle, and finally the filled soil is flattened by the bulldozer. However, the above method has the following shortcomings: 1. Different vehicles and multiple staff members are required to cooperate with each other to fill the soil, and the processing process is relatively complicated; 2. After the soil is backfilled, some coarser particles (such as stones) are in contact with the pipeline at the bottom, which will easily cause damage to the pipeline during the subsequent compaction process.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-7 The present invention discloses a pipe backfilling device for an underground water pipe, comprising a shell having an open top, and a filter assembly 3 is arranged at the open top of the shell, the filter assembly 3 is used to filter the soil material entering therein, divide the soil material into smaller particles and larger particles, and discharge the smaller particles and the larger particles of soil material respectively, one side of the shell is connected to a vehicle body, the shell is driven by the vehicle body and can move above the pipe trench, one side of the shell is provided with a feeding device 2, the feeding device 2 is used to transport and lift the soil material and put it into the filtering assembly 3.

[0034] In one embodiment, a filling component 4 is also included. The feed end of the filling component 4 is located at the bottom of the discharge end of the filter component 3. The discharge end of the filling component 4 extends outside the shell and is arranged downward. The filling component 4 is used to receive the smaller particles and larger particles of soil discharged respectively, and first output the smaller particles of soil into the ditch, and then output the larger particles of soil into the ditch. A compaction roller 6 is rotatably provided at the bottom of the shell. The compaction roller 6 is used to compact the smaller particles of soil in the ditch before the larger particles of soil cover the smaller particles of soil.

[0035] In the specific implementation, the staff sits on the vehicle body and drives the vehicle body to move forward so that the device can move together. In this process, the feeding device 2 moves synchronously and is inserted horizontally into the soil material beside the trench. At this time, the feeding part of the feeding device 2 is in contact with the soil material. When the feeding device 2 is started, the soil will be lifted by the feeding device 2 and transferred to the filtering component 3. The filtering component 3 filters out the larger particles in the soil. The filtered soil material is put into the filling component 4. At this time, the filling component 4 is started to make the filling component 4 put the smaller particles of soil material into the trench. After the feeding is completed, the vehicle body continues to drive the device forward, so that the compaction roller 6 passes through the pipe ditch where the material has been fed. The compaction roller 6 will compact the smaller particles of soil in the pipe ditch. After the compaction is completed, the larger particles of soil are output to the pipe ditch. The device can load, filter, feed and compact the soil in sequence, without the need for multiple vehicles to cooperate in the construction, which can effectively improve the construction efficiency and convenience. After the soil is filtered, only finer particles will contact the pipeline, so it will not cause damage to the pipeline during subsequent compaction and normal use.

[0036] In one embodiment, the shell includes a mounting shell 1, and the feeding device 2 includes a mounting frame 21 installed on the side wall of the mounting shell 1. A Z-type bucket elevator 23 is slidably installed on the mounting frame 21, and a hydraulic push rod 22 is installed on the mounting frame 21 to drive the Z-type bucket elevator 23 to move perpendicular to the travel direction of the mounting shell 1. The Z-type bucket elevator 23 includes two horizontal parts distributed up and down in a Z-shaped combination and a vertical part connecting the two horizontal parts. Both horizontal parts have inlet and outlet ports 24, and the inlet and outlet port 24 of the top horizontal part is located directly above the feeding end of the filter component 3. A hydraulic platform 25 is also installed on the bottom horizontal part, and an inclined conveying platform 26 is installed at the telescopic end of the hydraulic platform 25. The conveying platform 26 is inclined downward on the side away from the Z-type bucket elevator 23, and an arc-shaped guide platform 27 is provided at its lower inclined end. The arc-shaped guide platform 27 is surrounded by slopes, and the output end of the conveying platform 26 is located directly above the inlet and outlet ports 24 on the bottom horizontal part.

[0037] In a specific implementation, when digging the trench, the excavated soil will accumulate on the side of the trench. Since the edge of the arc-shaped guide platform 27 is inclined, when the shell moves above the trench, the arc-shaped guide platform 27 can be inserted into the soil piled in all directions except one side close to the input end of the conveying platform 26. In actual circumstances, the top wall of the arc-shaped guide platform 27 may have a downwardly concave inclined groove, which corresponds to the output end of the conveying platform 26. Therefore, when the arc-shaped guide platform 27 is inserted into the soil, part of the soil will be conducted to the input end of the conveying platform 26 through the inclined direction of the groove. After the conveying platform 26 works, it will transport the soil at the soil pile to the Z-type bucket elevator 23. After the Z-type bucket elevator 23 is started, the soil entering it will be lifted and transported to the filter assembly 3, thereby completing the transportation of the soil.

[0038] It should be noted that when the hydraulic push rod 22 drives the Z-type bucket elevator 23 to move in a direction perpendicular to the moving direction of the mounting shell 1, the moving distance of the inlet and outlet ports of the top transverse portion corresponds to the size of the feed end of the filter assembly 3. When the hydraulic push rod 22 drives the Z-type bucket elevator 23 to move, the inlet and outlet ports of the top transverse portion can always transport the soil material to the feed end of the filter assembly 3, thereby preventing leakage during transportation.

[0039] The device can also be used to transport sand into the filter assembly 3. The above-mentioned conveying platform 26 and Z-type bucket elevator 23 are common knowledge in the field, so the specific structural composition and working principle will not be described in detail in this article.

[0040] In one embodiment, the opening on the shell is opened at the top of the mounting shell 1, and the filter assembly 3 includes a filter box 31 inserted in the opening and can slide up and down. The top of the filter box 31 is open and used to guide the soil material output from the Z-type bucket elevator 23 into the filter box 31. A telescopic rod 32 is vertically installed on the mounting shell 1, and a spring in contact with its telescopic end is installed in the telescopic rod 32. The filter box 31 is connected to the telescopic end of the telescopic rod 32. A power source is installed on the filter box 31, and the power source can be a vibration motor. The power source is used to vibrate the filter box 31. A filter plate 33 is obliquely installed in the filter box 31. A discharge port 34 is opened at the bottom of the filter box 31, and the filter plate 33 is located above the discharge port 34. A discharge port 35 is opened on the side of the filter box 31 corresponding to the filter plate 33 and tilted downward. The mounting shell 1 includes a mounting shell 11, and a guide plate 13 is installed at the side wall of the mounting shell 11 corresponding to the discharge port 35, and an opening is opened on the side wall of the mounting shell 11 corresponding to the guide plate 13.

[0041] In a specific implementation, when soil is transported to the filter assembly 3 by the Z-type bucket elevator 23, the soil will pass through the opening of the filter box 31 and enter the filter box 31. Then, the soil will fall on the filter plate 33. The filter plate 33 can filter out larger particles in the soil. The smaller particles filtered out of the soil pass through the discharge port 34 and are transmitted to the filling assembly 4, while the larger particles are discharged to the outside of the filter box 31 through the discharge port 35. The setting of the guide plate 13 and the opening can guide the larger particles output from the filter box 31 to be discharged outside the mounting shell 1. After the soil is filtered, the soil in contact with the pipeline can be smaller particles, so that the pipeline surface will not be damaged.

[0042] In one embodiment, a swing assembly 5 is further provided on the housing.

[0043] With such a design, when the swing assembly 5 is working, it can drive the filling assembly 4 to swing back and forth, so that the output end of the filling assembly 4 can evenly spray smaller particles of soil into the pipe trench.

[0044] In one embodiment, a strip-shaped and laterally arranged swinging groove 12 is opened on the side wall of the mounting shell 11, and the filling component 4 includes a feed hopper 41 rotatably installed in the mounting shell 11, and the feed hopper 41 is located at the bottom of the filter component 3. A discharge pipe 42 is installed on the side wall of the feed hopper 41 and is interconnected with the feed hopper 41 and passes through the swinging groove 12. The end of the discharge pipe 42 away from the feed hopper 41 has a downwardly arranged discharge port, and a auger component 43 is arranged on the discharge pipe 42. The auger component 43 includes an auger and a driving motor for driving the auger to rotate, and the driving motor is installed on the discharge pipe 42, and the auger is rotatably installed in the discharge pipe 42 and the feed hopper 41.

[0045] In a specific implementation, the screened soil enters the feed hopper 41. When the driving motor is started, the rotation of the auger is used to transport the soil in the feed hopper 41 and the discharge pipe 42 to the discharge port of the discharge pipe 42, and the soil falls into the pipe trench from the discharge port. The moving end of the swing assembly 5 is connected to the rotating connection between the feed hopper 41 and the mounting shell 11. When the swing assembly 5 is working, the feed hopper 41 and the discharge pipe 42 swing together. The swing range of the discharge pipe 42 corresponds to the swing groove 12. The swing amplitude of the swing assembly 5 and the length of the swing groove 12 are both adapted to the width of the pipe trench, so that the soil can only be thrown into the pipe trench and will not spill out.

[0046] In one embodiment, the swing assembly 5 includes a mounting column 51 arranged at the rotating connection between the feed hopper 41 and the mounting shell 11, the mounting column 51 is connected to the feed hopper 41, and the side thereof away from the feed hopper 41 extends out of the side 11 of the mounting shell, a connecting rod 52 is installed on the side of the mounting column 51 located outside the mounting shell 11, a rotating disk 53 is rotatably installed on the bottom wall of the mounting shell 11, a mounting sleeve 54 is rotatably installed at the eccentric portion of the rotating disk 53, the mounting sleeve 54 is slidably mounted on the connecting rod 52, and a control motor 55 for driving the rotating disk 53 to rotate is installed on the mounting shell 11, and the control motor 55 will not contact the feed hopper 41.

[0047] In a specific implementation, when the control motor 55 is started, the rotating disk 53 rotates, and the mounting sleeve 54 at its eccentric position drives the connecting rod 52 to swing back and forth around the connection with the feed hopper 41, thereby causing the feed hopper 41 to swing around the connection with the connecting rod 52.

[0048] In one embodiment, a traveling wheel assembly 7 is provided at the bottom of the mounting shell 1, and the traveling wheel assembly 7 includes a lifting assembly 71 installed at the bottom of the mounting shell 1. The lifting assembly 71 can adopt a hydraulically powered push rod, and a wheel body 72 is rotatably installed at the moving end of the lifting assembly 71. The spacing of the wheel bodies 72 is greater than the length of the compaction roller 6, so the wheel bodies 72 are in contact with the ground on both sides of the trench. The lifting assembly 71 is used to drive the wheel body 72 to move up and down, so as to change the load-bearing weight of the compaction roller 6.

[0049] In this design, the wheel body 72 is driven to move upward or downward by the lifting component 71. When the wheel body 72 moves upward, it gradually leaves the ground. At this time, the center of gravity of the device gradually gathers on the compacting roller 6, so that the compacting roller 6 compacts the soil more tightly; conversely, when the wheel body 72 moves downward, its contact with the ground increases. At this time, the center of gravity of the device is gradually shared by the wheel body 72, so that the compaction degree of the soil by the compacting roller 6 decreases. This method can adjust the compaction strength of the soil according to demand, and will neither cause uneven soil compaction to produce hollows nor over-compact and damage the pipeline. In actual situations, several lifting gears can be set on the lifting component 71, or a pressure sensor can be used on the compacting roller 6 to accurately know the compaction condition of the compacting roller 6.

[0050] In one embodiment, the filling assembly 4 also includes a storage shell 8, which includes a storage box 81 connected to a side of the mounting shell 11 away from the discharge port of the discharge pipe 42, and a feed port 82 is provided on a side of the storage box 81 close to the mounting shell 11, and the feed port 82 is communicated with the opening on the mounting shell 11, and can guide larger particles to be discharged into the storage box 81 along the guide plate 13. The storage box 81 is used to collect larger particles, and a debris discharge port 83 is provided on a side of the storage box 81 close to the mounting shell 11, and the discharge end of the debris discharge port 83 faces downward, and another compaction roller 6 is rotatably installed at the bottom of the storage box 81, and the debris discharge port 83 is located between the two compaction rollers 6. A discharge plate (not shown in the figure) that is electrically controlled is installed at the corresponding debris discharge port 83 of the storage box 81. When the discharge plate is opened, the larger particles inside the storage box 81 can be discharged from the debris discharge port 83 to the outside of the storage box 81.

[0051] In a specific implementation, larger particles (such as gravel) filtered out by the filter assembly 3 will pass through the feed port 82 into the storage box 81, and the storage box 81 can store them. Moreover, after the discharge plate is controlled to be opened, the larger particles in the storage box 81 can be discharged from the discharge port 83 to between the two compaction rollers 6. The larger particles cover the filled trench. As the shell moves forward, the compaction roller 6 at the bottom of the storage box 81 will further compact the gravel above the soil layer. When there is traffic load above the trench, the gravel layer can disperse these pressures, reduce the direct compressive stress on the pipeline, and protect the pipeline from damage, thereby effectively increasing the strength of the soil after backfilling. The discharge plate controlled electrically in the above-mentioned method is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0052] In one embodiment, a travel assist component 9 is provided on the shell, and the travel assist component 9 includes a connecting frame 91 installed on the side wall of the storage box 81. The vehicle body is connected to the storage box 81 through the connecting frame 91. A camera 92 connected to the vehicle body signal is installed on the side of the mounting shell 11 close to the exhaust pipe 42. The camera 92 is used to monitor the front of the mounting shell 11 in real time and transmit the image to the vehicle body.

[0053] In a specific implementation, a worker can sit on the vehicle body to control the movement of the device, and the camera 92 has the function of observing the image in front of the equipment in real time, and displaying the image on the vehicle body so that the worker can view the situation in real time. In actual situations, another camera 92 can be installed at the corresponding discharge port of the discharge pipe 42. The camera 92 is used to monitor the filling condition inside the trench in real time and transmit the image to the vehicle body so that the worker can ensure that the trench is filled evenly.

[0054] See also Figure 8 The vehicle body can also be installed on the mounting shell 1 through an articulated device, and the vehicle body is located at the front side of the moving direction of the device, so the staff can drive the device to move without the camera 92. The articulated device mentioned above is common knowledge in the field, so the specific structural composition and working principle will not be described in detail in this article.
