Description

Technical Field

[0002] In the current field of water supply and drainage pipeline construction, before installing the water supply and drainage pipeline, it is necessary to use an excavator to dig a ditch, and then install the water supply and drainage pipeline in the excavated ditch. After the water supply and drainage pipeline is installed, it is necessary to use an excavator again to fill the soil accumulated on both sides of the ditch on the installed pipeline. Since the soil excavated by the excavator is mostly in the form of large blocks, when filling the installed water supply and drainage pipeline, it is difficult to fill the narrow space on the side and bottom of the water supply and drainage pipeline with soil, resulting in poor stability of the installed water supply and drainage pipeline, making it difficult to engage and compact each other, and the risk of settlement of the landfill layer is high, which may cause deformation and damage of the pipeline in the later stage. In addition, the traditional landfill process often requires repeated operations by excavators or manual secondary processing, and the construction process is cumbersome and consumes a lot of time and labor costs.

The soil conveying box 5 is located between the ditching assembly and the pipeline loading box 2, and the soil conveying box 5 is used to convey the soil generated by the ditching assembly when digging the ditch upward. The two side walls of the soil conveying box 5 are both inclined, that is, the width of the upper port of the soil conveying box 5 is greater than the width of its bottom, which makes it convenient for the soil conveying box 5 to salvage the soil at the bottom of the ditch and convey it upward, thereby facilitating the cleaning of the soil generated by the ditching assembly during the ditching process.

When the first electric telescopic rod 13 pushes the limit frame 11 and the water supply and drainage pipe inside it away from the first electric telescopic rod 13, it drives the baffle 12 to push toward the limit plate 10. When the limit frame 11 is located directly above the pipe outlet 15, the baffle 12 covers the lower end surfaces of the two limit plates 10, thereby preventing the water supply and drainage pipe on the limit plate 10 from sliding downward.

[0063] The pipeline installation assembly includes a mechanical arm 16 , the upper end of which is fixedly connected to the bottom of the base 1 .

The wires on the first servo motor 20 are electrically connected to the storage device in the prior art, such as a battery, so that the output shaft of the first servo motor 20 drives the first threaded rod 19 to rotate forward and reverse.

[0067] The moving block 21 is threadedly connected to the first threaded rod 19, and the moving block 21 is slidably connected to the connecting plate 18. The upper end of the lifting baffle 3 is fixedly connected to the side wall of the moving block 21. The longitudinal section of the connecting plate 18 is a vertically set U-shape.

[0069] The first drive motor 24 is fixedly connected to the fixed plate 4. The output shaft of the first drive motor 24 passes through the fixed plate 4 and is fixedly connected to one of the rotating rods 22.

[0070] The crushing teeth 25 are multiple and fixedly connected to the circumferential wall of the rotating rod 22, and the multiple crushing teeth 25 are spirally distributed on the circumferential wall of the rotating rod 22. The crushing teeth 25 are evenly distributed in a spiral manner, and the vertical distance between two adjacent crushing teeth 25 on the left and right is less than the diameter value of the crushing teeth 25, showing a closely arranged state. This distribution method enables the crushing teeth 25 to continuously and finely crush the soil on the side wall opposite to the rotating rod 22 in the ditch during the process of the rotating rod 22 driving the crushing teeth 25 to rotate, thereby not only realizing the excavation of the ditch, but also effectively improving the efficiency and quality of crushing soil blocks.

[0071] The upper and lower ends of the lifting baffle 3 are rotatably connected to the rotating shaft 26, and a transmission roller 27 is fixedly connected to the rotating shaft 26. The upper and lower adjacent transmission rollers 27 are sleeved with a conveyor belt 28, and the side walls of the conveyor belt 28 are fixedly connected with a fixed block 29. The outer side wall of the soil conveying box 5 is fixedly connected to the side wall of the fixed block 29. The side wall of the lifting baffle 3 is fixedly connected with a symmetrically arranged third drive motor 43. The third drive motor 43 is located at the upper end of the lifting baffle 3, and the output shaft of the third drive motor 43 is fixedly connected to the end of the transmission roller 27. The transmission roller 27 is driven to rotate by the output shaft of the third drive motor 43, thereby driving the conveyor belt 28 to rotate, and the soil conveying box 5 is transported upward through the conveyor belt 28.

[0072] A guide plate 30 is fixedly connected to the side wall of the lifting baffle 3, and the guide plate 30 cooperates with the soil conveying box 5. The longitudinal section of the guide plate 30 is arc-shaped, and the guide plate 30 is located between the two adjacent soil conveying boxes 5 on the left and right. When the conveyor belt 28 drives the fixed block 29 on its side wall and the soil conveying box 5 to move to the top of the transmission roller 27, the open end of the soil conveying box 5 is at its side. At the same time, since the side wall of the soil conveying box 5 is inclined, the soil loaded in the soil conveying box 5 slides down the inclined surface of the soil conveying box 5 into the guide plate 30.

[0073] A soil collecting box 31 is fixedly connected to the side wall of the lifting baffle 3 , and the lower end of the guide plate 30 passes through the side wall of the lifting baffle 3 and extends into the soil collecting box 31 .

[0074] The bottom of the soil collecting box 31 is fixedly connected to a soil conveying cylinder 32 which is arranged obliquely. The bottom of the soil conveying cylinder 32 is provided with an inlet which cooperates with the material guide plate 30 .

[0081] Working principle: through existing technical means such as excavators, a pit is excavated at the end of the ditch for installing the water supply and drainage pipes. The depth of the pit is the installation depth of the water supply and drainage pipes, and its width is equal to the distance between the two lifting baffles 3 and the distance between the two faces. The length of the pit is equal to the length of the lifting baffle 3. Then start the first servo motor 20 and the second servo motor 39. The output shaft of the first servo motor 20 drives the first threaded rod 19 to rotate. At the same time, the output shaft of the second servo motor 39 drives the second threaded rod 38 to rotate. The moving block 21 threadedly connected to the first threaded rod 19 is limited by the strip groove of the connecting plate 18 and the slider, so that the moving block 21 and the sliding block 40 synchronously drive the lifting baffle 3 and the discharge pipe 36 to move downward, and drive the ditching assembly and the soil conveying box 5 to move downward. When the bottom of the pit excavated by the lower end face of the lifting baffle 3 is When the two parts come into contact, the first servo motor 20 stops working, so that the height value of the downward movement of the lifting baffle 3 can be adjusted according to the installation depth of the water supply and drainage pipe. Then, the driving device at the bottom of the base 1 drives the walking track 9 to move forward, pushing the device forward. At the same time, the first driving motor 24 is started to drive one of the rotating rods 22 to rotate, and the other rotating rod 22 is rotated synchronously through the mutually meshing first gear 23. A plurality of crushing teeth 25 tightly arranged in a spiral shape on the circumferential wall of the rotating rod 22 rotate accordingly, and the soil on the side opposite to the rotating rod 22 in the pit is continuously and finely crushed, and the required ditch is gradually excavated, thereby realizing the excavation of the ditch. The lifting baffle 3 is tilted away from one end face of the pipe loading box 2. During the forward movement of the device, the tip can reduce the travel resistance to ensure the smooth progress of the ditching operation.

[0082] The soil generated by ditching is accumulated between the two lifting baffles 3. The third drive motor 43 on the side wall of the lifting baffle 3 is started, and its output shaft drives the transmission roller 27 to rotate, thereby making the conveyor belt 28 run. The fixed block 29 fixedly connected to the side wall of the conveyor belt 28 moves accordingly, driving the soil conveying box 5 to salvage the soil at the bottom of the ditch and transport it upward. The inclined side wall design of the soil conveying box 5, which is wide at the top and narrow at the bottom, is convenient for efficiently collecting soil. When the soil conveying box 5 moves to the top of the transmission roller 27, the soil in the box is pulled up by the side wall. The wall is inclined, and the soil slides into the soil collection box 31 through the guide plate 30. Then, the second drive motor 34 drives the spiral conveying plate 33 to rotate, sucking the soil from the bottom inlet of the soil conveying cylinder 32 and conveying it upward. The soil falls into the feed funnel 35 on the top of the soil screening box 6 through the discharge pipe 36 and the protective cover. The soil is screened on the inclined filter screen 41, and the fine soil particles pass through the sieve holes and are discharged from the fine soil discharge port 7 along the soil lead-out plate 42; larger soil blocks slide along the inclined surface of the filter screen 41 and are discharged from the soil block discharge port 8.

[0083] The water supply and drainage pipe is placed between two inclined limit plates 10. Since the distance between the lower ends of the two limit plates 10 is equal to the diameter of the outer ring wall of the pipe, the water supply and drainage pipe can naturally slide into the limit frame 11. When the base 1 drives the pipe loading box 2 to move to the top of the excavated ditch, the first electric telescopic rod 13 is started, the first electric telescopic rod 13 extends, and pushes the limit frame 11 to slide horizontally in the opposite direction of the pipe outlet 15, and drives the baffle 12 to move toward the direction of the limit plate 10. When the upper surface of the baffle 12 contacts the lower end surface of the limit plate 10, the baffle 12 gradually covers the gap formed between the two limit plates 10. The gap prevents the pipe above the limit plate 10 from continuing to slide down. When the limit frame 11 drives the water supply and drainage pipe inside it to move to just above the pipe outlet 15, the water supply and drainage pipe slides out of the pipe outlet 15 along the inclined guide plate 14 under the action of gravity and falls into the upper end of the mechanical claw 17. At this time, the mechanical claw 17 grabs the water supply and drainage pipe, and through the mechanical arm 16, it moves according to the instructions, driving the mechanical claw 17 to place the pipe accurately in the excavated ditch, so that the end of the water supply and drainage pipe is inserted into the end of the adjacent water supply and drainage pipe installed in the ditch, thereby completing the transportation and installation of the water supply and drainage pipe.

[0084] After the water supply and drainage pipe is installed, when the base 1 drives the soil screening box 6 to move above the installed water supply and drainage pipe, the spiral conveying plate 33 in the soil conveying cylinder 32 transports the soil at its bottom through the discharge pipe 36 and the feed funnel 35 to the soil screening box 6, and the soil slides down to the filter screen 41. Since the filter screen 41 is inclined, in the process of the soil rolling downward through the inclined surface of the filter screen 41, the relatively fine soil slides down through the holes on the filter screen 41 to the soil guide plate 42, and slides down through the inclined surface of the soil guide plate 42 and the fine soil discharge port 7 to the installed water supply and drainage pipe. The base 1 is provided with a strip hole that matches the fine soil discharge port 7, which makes it easy to fill the installed water supply and drainage pipe with fine soil. Since the particle size of the fine soil is smaller than the particle size of the soil block, and the fluidity of the fine soil is greater than that of the soil block The fluidity of the blocks, so when the fine soil slides down onto the water supply and drainage pipe, it slides to both sides through the side walls of the water supply and drainage pipe and fills the gap between the outer wall of the water supply and drainage pipe and the side of the ditch. When the lower end of the filter screen 41 moves to the top of the water supply and drainage pipe, the soil blocks remaining on the filter screen 41 slide down the inclined surface of the filter screen 41 and fall onto the water supply and drainage pipe and cover the fine soil above the water supply and drainage pipe, thereby realizing the first filling of the water supply and drainage pipe with fine soil and then the soil blocks. It can not only facilitate the filling of the narrow space around the water supply and drainage pipe with fine soil, improve the density of the landfill soil, reduce the voids and gaps around the pipe, thereby enhancing the stability of the pipe, but also enable the soil blocks to better bite and compact each other during filling, further improving the density and stability of the entire landfill layer, and reducing the possibility of settlement of the landfill soil in the later stage.

[0085] Before filling the water supply and drainage pipes with soil, existing technical means can be used, such as a smoke generator to fill the installed water supply and drainage pipes with smoke, and a monitoring camera is installed on the lower side of the base 1. The smoke generator and the monitoring camera, as well as the first electric telescopic rod 13, the mechanical arm 16, the mechanical claw 17, the first drive motor 24, the second drive motor 34, the third drive motor 43 and the driving equipment installed on the lower side of the base 1 are all connected to the background central processing through signals. When the water supply and drainage pipes are filled with smoke, the monitoring camera does not detect smoke leakage at the connection between the two adjacent water supply and drainage pipes, which means that there is no leakage at the connection between the two water supply and drainage pipes, and the bottom The driving device under the seat 1 can drive the walking crawler 9 to move forward, and continue to install the next section of the water supply and drainage pipe, and cover the installed water supply and drainage pipe with soil. When the monitoring camera detects smoke leakage at the connection point of two adjacent water supply and drainage pipes, it means that there will be water leakage at the connection point of the two water supply and drainage pipes. At this time, the monitoring camera will transmit the detected image information to the background central processing unit, and control the driving device on the base 1 to stop running through the background central processing unit, and control the mechanical claw 17 through the mechanical arm 16 to grab the installed water supply and drainage pipe and reinstall it for inspection, so as to facilitate timely water leakage detection of the installed water supply and drainage pipe.
