Description

Technical Field

[0001] This invention relates to the technical field of water supply and drainage pipeline construction, specifically to a water supply and drainage pipeline pre-embedding construction equipment. Background Technology

[0002] Water supply and drainage pipeline engineering involves the transportation and distribution of industrial water supply and domestic drinking water, as well as the collection, transportation and discharge of industrial wastewater, domestic sewage and rainwater. It can be divided into rigid cement pipes and polyethylene plastic pipes. During the construction of water supply and drainage pipelines, it is necessary to dig a tunnel in the planned pipeline route, place the water supply and drainage pipes inside the tunnel, and connect the pipes one by one with clamps, etc. Finally, the excavated soil is filled back into the tunnel.

[0003] During the excavation of the tunnel, incomplete removal of soil, sand and gravel can lead to an uneven bottom, which can cause the water supply and drainage pipes to tilt when placed. Therefore, during the installation of existing water supply and drainage pipes, external force is applied manually to press the pipes to ensure their levelness.

[0004] The following problems still exist in the existing construction process of pre-buried water supply and drainage pipelines: 1. After the existing tunnels are excavated, the water supply and drainage pipelines are placed directly inside the tunnels by manual labor or hoisting machines without compaction of the bottom of the tunnels. When laying polyethylene plastic pipes in tunnels with loose soil, the refilled soil may press the water supply and drainage pipelines and cause deformation at the bottom of the tunnel. In severe cases, it may cause the water supply and drainage pipelines to break, affecting their service life.

[0005] 2. Due to the accumulation of soil and gravel in certain areas of the tunnel, the water supply and drainage pipes may still tilt during the pressing process by external force. As a result, the ends of two adjacent tilted water supply and drainage pipes may not be aligned and parallel during the splicing process, affecting the splicing effect of the pipes. Summary of the Invention

[0006] The purpose of this invention is to provide a pre-embedded construction equipment for water supply and drainage pipelines. The compaction roller, through the cooperation of the counterweight and the elastic telescopic rod, compacts the bottom of the tunnel. The crushing mechanism can crush the compacted protrusions at the bottom of the tunnel and transport the crushed protrusions to the outside of the tunnel through the conveying part.

[0007] The present invention is achieved by the following technical solution: a water supply and drainage pipeline pre-embedded construction equipment, including a mobile frame with automatic moving function, two mobile frames are symmetrically arranged front and back, and a compaction mechanism and a crushing mechanism are installed between the two mobile frames from left to right.

[0008] The compaction mechanism includes a horizontal frame, with symmetrical elastic telescopic rods installed on the lower end face of the horizontal frame. A U-shaped frame is installed on the lower end face of the two elastic telescopic rods. A compaction roller is installed between the two vertical sections of the U-shaped frame via bearings. A symmetrical placement frame is installed on the upper end face of the horizontal section of the U-shaped frame, and multiple counterweights are snapped between the placement frames.

[0009] The crushing mechanism includes a C-shaped plate with its opening facing downwards. The two vertical sections of the C-shaped plate are respectively mounted on two movable frames. A lifting cylinder is installed on the lower end face of the horizontal section of the C-shaped plate. A mounting frame with a C-shaped structure and its opening facing downwards is provided below the lifting cylinder. The mounting frame is fixedly connected to the lower end face of the telescopic end of the lifting cylinder. A rotating roller is installed between the two vertical sections of the mounting frame through a bearing. Multiple sets of crushing blades are installed sequentially on the circumference of the rotating roller from front to back. A conveying part is provided on the right side of the mounting frame.

[0010] The mobile frame is placed on both sides of the excavated tunnel, with the compaction roller inside the tunnel. An appropriate number of counterweights are installed between the frames. During the movement of the mobile frame, the bottom of the tunnel is compacted by the cooperation of the elastic telescopic rod and the compaction roller. Then, the compacted protrusions inside the tunnel are crushed by the cooperation of the rotating roller and the crushing blade to ensure the flatness of the tunnel.

[0011] Optionally, the conveying unit includes a conveying frame, wherein the conveying frame is formed by connecting an inclined section and a horizontal section end to end, and conveying rollers running in a forward and backward direction are installed on the front and rear side walls of the upper and lower ends of the inclined section of the conveying frame via bearings, and a conveyor belt is installed between the conveying rollers, and conveying blades are evenly installed on the conveyor belt.

[0012] Optionally, a fixed frame is installed on the upper surface of the horizontal section of the rear movable frame, and a material leakage box is installed on the fixed frame. The lower end of the material leakage box has a discharge port. A sliding frame is installed on the horizontal section of the rear movable frame in front of the material leakage box. An automatically resetting opening and closing plate is slidably installed on the sliding frame. A material leakage groove that passes through and cooperates with the discharge port is provided on the upper surface of the opening and closing plate. An inclined slope is provided on the front surface of the opening and closing plate. A vertically extending moving rod is slidably installed on the horizontal frame. The lower end of the moving rod is fixedly connected to the horizontal section of the C-shaped frame. A lifting block that cooperates with the inclined slope is installed on the upper end of the moving rod.

[0013] Optionally, the movable frame is an U-shaped structure with the opening facing downwards. Multiple movable wheels are evenly installed between the two vertical sections of the movable frame from left to right. Multiple anti-slip protrusions are evenly arranged on the circumference of the movable wheels. A scraper is installed on the lower end of the horizontal section of the movable frame above the movable wheels to scrape away the soil adhering to the anti-slip protrusions.

[0014] Optionally, guide plates are fixedly installed on the vertical sections of the two movable frames on opposite sides. Guide protrusions that slide with the guide plates are provided on both the front and rear sides of the inclined section of the conveying frame. The cooperation between the guide plates and the guide protrusions can ensure the stability of the conveying frame when moving up and down, and reduce the possibility of the conveying frame shaking when the conveying blades convey soil.

[0015] Optionally, a front-to-back extending spray pipe is installed on the lower end face of the horizontal section of the shaped frame. A water inlet pipe is installed on the left side of the spray pipe. Before the compaction operation, the water inlet pipe is connected to an external water pump. The spray pipe can spray water onto the compaction roller during the compaction process at the bottom of the tunnel, ensuring that the circumferential surface of the compaction roller is in a wet state. This reduces the adhesion between the circumferential surface of the compaction roller and the soil, thereby avoiding the problem of uneven compaction at the bottom of the tunnel caused by soil adhering to the circumferential surface of the compaction roller during the compaction process. This improves the compaction effect of the compaction roller on the bottom of the tunnel during the compaction process.

[0016] Optionally, the two vertical sections of the shaped frame are provided with connecting protrusions on the right side. A scraper plate that fits against the compaction roller is installed on both connecting protrusions. The scraper plate can further scrape off the soil adhering to the compaction roller, so as to avoid the problem of uneven compaction at the bottom of the tunnel caused by soil adhering to the circumference of the compaction roller during the compaction process.

[0017] Optionally, the rotating roller and the conveying roller are connected by a drive transmission method.

[0018] Compared with the prior art, the above-mentioned pressing device has the following advantages: 1. In the compaction mechanism designed in this invention, the moving compaction roller and the C-shaped frame cooperate with each other to compact the bottom of the tunnel, thereby reducing the possibility that the water supply and drainage pipe may be deformed or even broken at the bottom of the tunnel during the process of refilling soil, and improving the service life of the water supply and drainage pipe.

[0019] 2. In the crushing mechanism designed in this invention, the rotating roller can crush the protrusions formed by the compaction of soil and gravel inside the tunnel through the crushing blade during the rotation of the roller, thereby keeping the bottom of the tunnel flat, reducing the possibility of the water supply and drainage pipes tilting due to the protrusions, ensuring that the two ends of adjacent water supply and drainage pipes are aligned and parallel during the splicing process, and improving the alignment and splicing effect of the pipes.

[0020] 3. The conveyor roller designed in this invention can transport the crushed protrusions along the conveyor frame through the cooperation of the conveyor belt and the conveyor blades, so that the crushed soil and gravel can be transported to the outside of the tunnel without being manually shoveled out, reducing the time spent on manually removing the crushed protrusions and improving the efficiency of tunnel compaction.

[0021] 4. The spray pipe designed in this invention can spray water onto the compaction roller during the compaction process at the bottom of the tunnel, ensuring that the circumferential surface of the compaction roller is kept moist. This reduces the adhesion between the circumferential surface of the compaction roller and the soil, thereby avoiding the problem of uneven compaction at the bottom of the tunnel caused by soil adhering to the circumferential surface of the compaction roller during the compaction process, and improving the compaction effect of the compaction roller on the bottom of the tunnel during the compaction process.

Detailed Implementation

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] See Figure 1 A pre-embedded construction equipment for water supply and drainage pipelines includes a mobile frame 1 with automatic moving function. Two mobile frames 1 are symmetrically arranged front and back. A compaction mechanism 2 and a crushing mechanism 3 are installed between the two mobile frames 1 from left to right.

[0039] See Figure 7 as well as Figure 8The movable frame 1 is a U-shaped structure with its opening facing downwards. Multiple movable wheels 17 are evenly installed from left to right between the two vertical sections of the movable frame 1. Multiple anti-slip protrusions 18 are evenly arranged on the circumference of the movable wheels 17. A scraper 19 is installed on the lower end of the horizontal section of the movable frame 1, above the movable wheels 17, to scrape off the soil adhering to the anti-slip protrusions 18. Because the soil scattered during the excavation of the tunnel makes the sides of the tunnel quite muddy, the anti-slip protrusions 18 and the movable wheels 17 work together to ensure that the movable wheels 17 will not slip during movement. The scraper 19 can scrape off the soil adhering to the anti-slip protrusions 18 and the movable wheels 17, so as to prevent the soil adhering to the movable wheels 17 from affecting the smoothness of the movement of the movable wheels 17.

[0040] See Figure 2 as well as Figure 3 The compaction mechanism 2 includes a horizontal frame 21. The lower end face of the horizontal frame 21 is equipped with symmetrical elastic telescopic rods 22. The lower end faces of the two elastic telescopic rods 22 are jointly equipped with a U-shaped frame 23. A compaction roller 24 is installed between the two vertical sections of the U-shaped frame 23 through a bearing. The upper end face of the horizontal section of the U-shaped frame 23 is equipped with symmetrical placement frames 25. Multiple counterweights 26 are snapped between the placement frames 25.

[0041] In practice, the mobile frame 1 is placed on both sides of the excavated tunnel, with the compaction roller 24 positioned inside the tunnel. A suitable number of counterweights 26 are then installed between the placement frames 25. The counterweights 26, through the cooperation of the placement frames 25 and the U-shaped frame 23, drive the compaction roller 24 to move down and abut against the bottom of the tunnel. At this time, the elastic telescopic rod 22 is stretched. As the mobile frame 1 moves along the tunnel, the compaction roller 24 and the counterweights 26 work together to compact the bottom of the tunnel, thereby reducing the possibility of deformation or even breakage of the water supply and drainage pipes at the bottom of the tunnel during the refilling process, and improving the service life of the water supply and drainage pipes. During the compaction operation, the elastic telescopic rod 22 works with the U-shaped frame 23 to keep the compaction roller 24 in contact with the bottom of the tunnel. The counterweights 26 can provide sufficient pressure to the compaction roller 24, making the compaction roller 24 compact the bottom of the tunnel more thoroughly.

[0042] During the movement of the mobile frame 1, the compaction roller 24 can compact the bottom of the tunnel. When there is residual soil and gravel at the bottom of the tunnel due to incomplete cleaning, the compaction roller 24 will press the residual soil and gravel into a bulge.

[0043] See Figure 4The lower end face of the horizontal section of the shaped frame 23 is equipped with a front-to-back extending spray pipe 231. A water inlet pipe 232 is installed on the left side of the spray pipe 231. Before the compaction operation, the water inlet pipe 232 is connected to an external water pump. The spray pipe 231 can spray water on the compaction roller 24 during the compaction process at the bottom of the tunnel to ensure that the circumferential surface of the compaction roller 24 is in a wet state, reduce the adhesion between the circumferential surface of the compaction roller 24 and the soil, and thus avoid the problem of uneven compaction at the bottom of the tunnel caused by the adhesion of soil on the circumferential surface of the compaction roller 24 during the compaction process, thereby improving the compaction effect of the compaction roller 24 on the bottom of the tunnel during the compaction process.

[0044] See Figure 2 The two vertical sections of the shaped frame 23 are provided with connecting protrusions on the right side. A scraper 241 that fits against the compaction roller 24 is installed on the two connecting protrusions. The scraper 241 can further scrape off the soil adhering to the compaction roller 24, so as to avoid the problem of uneven compaction at the bottom of the tunnel caused by soil adhering to the circumference of the compaction roller 24 during the compaction process.

[0045] See Figure 5 as well as Figure 6 A fixed frame 11 is installed on the upper surface of the horizontal section of the rear movable frame 1. A material leakage box 12 is installed on the fixed frame 11. A material leakage box 12 has a discharge port at its lower end. A sliding frame 13 is installed on the horizontal section of the rear movable frame 1 and in front of the material leakage box 12. An automatically reset opening and closing plate 14 is slidably installed on the sliding frame 13. A material leakage groove 141 that passes through and cooperates with the discharge port is provided on the upper surface of the opening and closing plate 14. An inclined slope is provided on the front surface of the opening and closing plate 14. A vertically extending moving rod 15 is slidably installed on the horizontal frame 21. The lower end of the moving rod 15 is fixedly connected to the horizontal section of the U-shaped frame 23. A lifting block 16 that cooperates with the inclined slope is installed on the upper end of the moving rod 15.

[0046] The lifting block 16 is spaced apart from the inclined plane by an acceptable error distance. The discharge port is located behind the moving frame 1. In the initial position, the leakage trough 141 is offset from the discharge port and is not connected. After the compaction operation at the bottom of the tunnel is completed, the moving frame 1 is reset to the initial position, and lime is poured into the leakage box 12. The moving frame 1 moves again. When the moving frame 1 moves to the protruding position, the compaction roller 24 drives the U-shaped frame 23 to move upward through the cooperation of the protrusion and the elastic telescopic rod 22. Then, the U-shaped frame 23 drives the lifting block 16 to move upward through the moving rod 15. When the height of the protrusion is less than the acceptable error distance, the lifting block 16 does not contact the inclined plane. When the height of the protrusion is greater than the acceptable error height, the lifting block 16 moves upward through the inclined plane and drives the opening and closing plate 14 to move backward. Then, the leakage trough 141 is connected to the discharge port. At this time, the lime leaks from the processing port and the leakage trough 141 and falls on the ground behind the tunnel.

[0047] See Figure 9 as well as Figure 10 The crushing mechanism 3 includes a U-shaped plate 31 with its opening facing downwards. The two vertical sections of the U-shaped plate 31 are respectively mounted on two movable frames 1. A lifting cylinder 32 is installed on the lower end face of the horizontal section of the U-shaped plate 31. A mounting frame 33 with a U-shaped structure and its opening facing downwards is provided below the lifting cylinder 32. The mounting frame 33 is fixedly connected to the lower end face of the telescopic end of the lifting cylinder 32. A rotating roller 34 is installed between the two vertical sections of the mounting frame 33 through a bearing. Multiple sets of crushing blades 35 are installed sequentially from front to back on the circumference of the rotating roller 34. A conveying part 36 is provided on the right side of the mounting frame 33.

[0048] See Figure 10 The crushing blade 35 consists of a crushing part 351 and a pushing part 352. The length of the protrusion in the left-right direction is determined according to the length of the lime drop. The lifting cylinder 32 is activated to drive the mounting frame 33 to move down, so that the crushing blade 35 contacts the protrusion. A motor is installed on the mounting frame 33, and the output shaft of the motor is connected to the rotating roller 34. The motor is activated to drive the rotating roller 34 to rotate. During the rotation of the rotating roller 34, the crushing blade 35 crushes the protrusion. The height of the protrusion is determined according to the amount of lime drop (the higher the protrusion, the longer the time of connection between the discharge port and the leakage trough 141, and the more lime drops). When the protrusion is high, the lifting cylinder 32 drives the mounting frame 33 to move down slowly to avoid the crushing blade 35 colliding with the protrusion and causing damage to the crushing blade 35. During the crushing process, the pushing part 352 of the crushing blade 35 can push the crushed protrusion into the conveying part 36, so that the crushed protrusion is transported to the outside of the tunnel through the conveying part 36.

[0049] See Figure 11 as well as Figure 12 The conveying unit 36 ​​includes a conveying frame 361, wherein the conveying frame 361 is formed by connecting an inclined section and a horizontal section end to end. The front and rear side walls of the upper and lower ends of the inclined section of the conveying frame 361 are equipped with conveying rollers 362 that run in a forward and backward direction through bearings. A conveyor belt 363 is installed between the conveying rollers 362. Conveying blades 364 are evenly installed on the conveyor belt 363.

[0050] The rotating roller 34 and the conveying roller 362 are connected by a drive transmission method.

[0051] During operation, as the installation frame 33 moves downward, the conveyor frame 361 moves downward simultaneously. The crushed protrusions are pushed to the right by the actuating part 352 and enter the interior of the conveyor roller 362. At this time, the rotating roller 34 drives the lower conveyor roller 362 to rotate via belt drive. The lower conveyor roller 362 and the upper conveyor roller 362 cooperate with each other to drive the conveyor blades 364 to rotate via the conveyor belt 363. The conveyor blades 364 can transport the crushed protrusions through the interior of the conveyor frame 361 to the outside of the tunnel for unified collection and processing. This allows the crushed soil and gravel to be transported to the outside of the tunnel without manual shoveling, reducing the time spent manually removing the crushed protrusions and improving the efficiency of tunnel compaction. The rotating roller 34 and the conveyor roller 362 are connected to each other via belt drive. During the compaction operation, a single motor can achieve synchronous rotation of the two, reducing the use of a drive, saving costs, and reducing energy consumption.

[0052] See Figure 9 Guide plates 10 are fixedly installed on the vertical sections of the two movable frames 1 on opposite sides. Guide protrusions 111 that slide with the guide plates 10 are provided on both the front and rear sides of the inclined section of the conveying frame 361. The guide plates 10 and the guide protrusions 111 cooperate with each other to ensure the stability of the conveying frame 361 when moving up and down, and reduce the possibility of the conveying frame 361 shaking when the conveying blades 364 convey soil.

[0053] The above-mentioned water supply and drainage pipeline pre-embedding construction equipment includes the following steps in the pre-embedding construction of water supply and drainage pipelines: Step 1, pre-treatment: Place the mobile frame 1 on both sides of the excavated tunnel and place the compaction roller 24 inside the tunnel, and then install an appropriate number of counterweights 26 between the placement frames 25.

[0054] Step 2, compaction: The counterweight 26, through the cooperation of the placement frame 25 and the C-shaped frame 23, drives the compaction roller 24 to move down and abut against the bottom of the tunnel. At this time, the elastic telescopic rod 22 is stretched. As the moving frame 1 moves along the tunnel, the compaction roller 24 and the counterweight 26 cooperate to compact the bottom of the tunnel.

[0055] Step 3, Marking Processing: Pour lime into the material leakage box 12, and the moving frame 1 moves again. When the moving frame 1 moves to the protruding position, the compaction roller 24, through the protrusion and the elastic telescopic rod 22, drives the U-shaped frame 23 to move upward. Then, the U-shaped frame 23 drives the lifting block 16 to move upward through the moving rod 15. When the height of the protrusion is less than the acceptable error distance, the lifting block 16 does not contact the inclined surface. When the height of the protrusion is greater than the acceptable error height, the lifting block 16 moves upward and drives the opening and closing plate 14 to move backward through the inclined surface. Then, the material leakage trough 141 is connected to the discharge port. At this time, the lime leaks from the treatment port and the material leakage trough 141 and falls on the ground behind the tunnel.

[0056] Step 4, Crushing and Collection: Start the lifting cylinder 32 to move the mounting frame 33 down, so that the crushing blade 35 contacts the protrusion. The mounting frame 33 is equipped with a motor, and the output shaft of the motor is connected to the rotating roller 34. Start the motor to drive the rotating roller 34 to rotate. During the rotation of the rotating roller 34, the crushing blade 35 crushes the protrusion. The rotating roller 34 drives the lower conveyor roller 362 to rotate through the belt drive. Then, the lower conveyor roller 362 and the upper conveyor roller 362 cooperate with each other to drive the conveyor blades 364 to rotate through the conveyor belt 363. Then, the conveyor blades 364 can transport the crushed protrusion through the inside of the conveyor frame 361 to the outside of the tunnel for unified collection and processing.
