Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and more specifically, to a municipal pipeline construction device. Background Art

[0002] There are two common construction methods for municipal pipeline construction, namely direct burial construction and pipe jacking construction. Direct burial construction is the most commonly used construction method for pipeline laying, which requires trench excavation and has a greater impact on the surrounding environment. Pipe jacking construction does not require excavation of external trenches. It only requires the use of the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, and to push the pipeline into the soil according to the designed slope and transport the soil away. It has less impact on the surrounding environment, but the cost is higher.

[0003] When installing pipelines directly buried, the bottom of the excavated trench is generally square to facilitate workers to enter the trench to install the pipelines. In the process of installing the pipelines, the pipelines are generally hoisted from pipeline transport vehicles into the trench by cranes and other existing technical equipment, and then the pipelines are installed. Since the bottom of the pipeline is in contact with the trench, if there are protrusions at the bottom of the trench, the interface parts of the two pipelines are at different heights, so the workers need to adjust the height of the pipeline, which increases the difficulty of pipeline installation.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1. In the present invention, the material storage box is pulled upward or pushed downward by the first electric telescopic rod, thereby adjusting the height value of the rear arc-shaped supporting plate, so that each arc-shaped supporting plate is located in the same plane, and then the pipe to be installed is placed on the arc-shaped supporting plate, and the pipe installed later is assembled and spliced ​​on the end of the pipe installed earlier. Since the arc-shaped supporting plate at the bottom of the pipe and the height of the arc-shaped supporting plate installed earlier are located in the same plane, the height of the pipe installed later is consistent with the height of the pipe installed earlier, thereby avoiding the staff from repeatedly adjusting the height and installation orientation of the pipe during the installation of the pipe, which not only improves the efficiency of the pipe installation, but also saves manpower and time.

[0042] 2. In the present invention, the soil falling in the discharge pipe is continuously pushed to the lower side of the pipe by the filling components, and the soil on the lower side of the pipe is compacted by the pushing of the filling components on both sides of the pipe, so that the pipe is supported by the compacted soil.

[0043] 3. In the present invention, the first covering plate is driven to move forward by moving the movable frame forward. In the process of moving the first covering plate forward, the soil on the ground on both sides of the groove for installing the pipeline is pushed forward. In the process of pushing the ground soil forward, the soil falls downward through the inclined surface of the first covering plate into the groove for installing the pipeline and covers the installed pipeline, thereby achieving coverage of the pipeline.

[0044] 4. In the present invention, the pipe to be installed is placed inside the groove through the arc-shaped bearing plate, that is, at this time, the bottom of the pipe is not in direct contact with the bottom of the groove. If there are protrusions at the bottom of the groove, it will not affect the horizontality of the pipe, and thus will not affect the height mismatch of the interface parts of the two pipes. After the pipe to be installed is placed inside the groove through the arc-shaped bearing plate, soil is filled under the arc-shaped bearing plate to ensure that the interface parts of the two pipes correspond to each other, which is convenient for installing and splicing the two pipes.

[0061] Reference Figures 1 to 15 .

[0062] Embodiment 1 further illustrates a municipal pipeline construction device proposed by the present invention.

[0063] A municipal pipeline construction device comprises: a mobile frame 1, on which a conveyor belt 2 is arranged; a positioning device, which is located at the lower side of the mobile frame 1, and the conveyor belt 2 is used to transmit the positioning device; a first covering plate 3, which is fixedly connected to the end of the mobile frame 1 and is used to scrape soil into a ditch where the municipal pipeline has been installed.

[0064] The positioning device includes: an arc-shaped bearing plate 4, which is used to carry municipal pipelines; a storage box 5, which is arranged on both sides of the arc-shaped bearing plate 4, and a limit plate 6 is arranged at the bottom of the storage box 5, and a support plate 7 is fixedly connected to the limit plate 6; a positioning nail 8, which is arranged at the bottom of the storage box 5, and the lower end of the positioning nail 8 passes through the limit plate 6 and extends to the lower side of the limit plate 6; a positioning plate 9, a feed hopper 10 is fixedly connected to the upper surface of the positioning plate 9, and a discharge pipe 11 is fixedly connected to the lower end of the feed hopper 10, and the discharge pipe 11 is fixedly connected to the support plate 7; a first electric telescopic rod 12, which is arranged between the positioning plate 9 and the storage box 5, and the first electric telescopic rod 12 is used to adjust the height of the arc-shaped bearing plate 4; a filling component, which is arranged on the limit plate 6, and the filling component cooperates with the discharge pipe 11 to fill the lower side of the arc-shaped bearing plate 4.

[0065] The support plate 7 is an inverted "U" shape, the lower end of the discharge pipe 11 passes through the top of the support plate 7 and extends to the upper side of the filling component, and a slide groove is opened on the outer wall of the support plate 7, and a slider is fixedly connected to the outer wall of the storage box 5, and the slider is slidably connected in the slide groove to facilitate the up and down movement of the storage box 5.

[0066] When it is necessary to install the municipal pipeline, the mobile frame 1 is placed above the groove for installing the pipeline, and the four corners of the mobile frame 1 are located on the ground on both sides of the groove. The positioning device is transported into the groove by the conveyor belt 2, and the first electric telescopic rod 12 is started. The first electric telescopic rod 12 pushes the storage box 5 downward, driving the storage box 5 to move downward. The downward movement of the storage box 5 pushes the positioning nail 8 downward, so that the positioning nail 8 is inserted into the bottom of the groove for installing the pipeline. At the same time, the limit plate 6 contacts with the bottom of the groove for installing the pipeline, that is, the installation of the arc-shaped bearing plate 4 is realized, and the laser level or line projection meter in the prior art is used to detect whether the multiple arc-shaped bearing plates 4 are located on the same plane. When the arc-shaped bearing plate 4 installed at the rear and the arc-shaped bearing plate 4 installed at the front are in contact with each other, the arc-shaped bearing plate 4 installed at the rear and the arc-shaped bearing plate 4 installed at the front are in contact with each other. When the heights of the plates 4 are different, the first electric telescopic rod 12 is started to pull the storage box 5 upward or push the storage box 5 downward, thereby adjusting the height value of the rear arc-shaped supporting plate 4 so that each arc-shaped supporting plate 4 is located in the same plane, and then the pipes to be installed are placed on the arc-shaped supporting plate 4, and the pipes installed later are assembled and spliced ​​on the ends of the pipes installed earlier. Since the arc-shaped supporting plate 4 at the bottom of the pipe and the height of the arc-shaped supporting plate 4 installed earlier are located in the same plane, the height of the pipes installed later is consistent with the height of the pipes installed earlier, thereby avoiding the staff from repeatedly adjusting the height and installation orientation of the pipes during the installation of the pipes, which not only improves the efficiency of the pipe installation, but also saves manpower and time.

[0067] After the pipeline is installed, the filling components are started to continuously push the soil falling in the discharge pipeline 11 to the lower side of the pipeline. The soil on the lower side of the pipeline is compacted by the pushing of the filling components on both sides of the pipeline, so that the pipeline is supported by the compacted soil.

[0068] The movable frame 1 is connected to the pipeline transport vehicle through existing equipment such as ropes. When the pipeline transport vehicle transports the pipeline to be installed and moves forward, the movable frame 1 is driven to move forward, and the conveyor belt 2 transports the positioning equipment to be installed forward. In the process of the movable frame 1 moving forward, the first covering plate 3 is driven to move forward. In the process of the first covering plate 3 moving forward, the soil on the ground on both sides of the groove for installing the pipeline is pushed forward. In the process of pushing the ground soil forward, the soil falls downward through the inclined surface of the first covering plate 3 into the groove for installing the pipeline and covers the installed pipeline, thereby covering the pipeline, wherein the ends of the two first covering plates 3 are in contact with each other and the ends of the first covering plates 3 that are consistent with the forward direction of the movable frame 1 are away from each other, that is, the two first covering plates 3 are in a "V" shape, so that when the first covering plate 3 moves, the soil falls through the inclined surface of the first covering plate 3 into the groove for installing the pipeline, so as to cover the installed pipeline.

[0069] The bottom of the mobile frame 1 is rotatably connected to at least two symmetrically arranged rollers 13, and a second covering plate 14 is arranged on one side of the roller 13. The second covering plate 14 is parallel to the first covering plate 3, and the length of the second covering plate 14 is less than the length of the first covering plate 3, and the lower end surfaces of the first covering plate 3, the second covering plate 14 and the roller 13 are flush; the mobile frame 1 is rotatably connected to a symmetrically arranged rotating shaft 15, and the rotating shaft 15 is fixedly connected to a symmetrically arranged pulley 16, and the conveyor belt 2 is sleeved on the pulley 16; the mobile frame 1 is fixedly connected to a first driving motor 17, and the output shaft of the first driving motor 17 is fixedly connected to the end of one of the rotating shafts 15, for driving the rotating shaft 15 and the conveyor belt 2 to rotate.

[0070] The second covering plate 14 is located on the side of the roller 13 away from the first covering plate 3. When the mobile frame 1 moves forward, the second covering plate 14 pushes the soil in front of the roller 13 forward, and the soil falls downward through the inclined surface of the second covering plate 14 into the groove for installing the pipe. When the second covering plate 14 passes through the feed hopper 10, the soil pushed by the second covering plate 14 falls into the feed hopper 10, and falls downward through the feed hopper 10 and the discharge pipe 11 to one side of the filling component, which not only replenishes the soil in front of the filling component, but also cleans the soil in the forward direction of the roller 13, thereby facilitating the roller 13 to roll forward.

[0071] At least two connecting plates 18 are fixedly connected to the conveyor belt 2. A groove 20 is provided on one end surface of the connecting plate 18 away from the conveyor belt 2. A rotating shaft 21 is rotatably connected to the side wall of the groove 20. A horizontally arranged transport plate 19 is fixedly connected to the rotating shaft 21. Limit rods 22 are inserted into the side walls of the transport plate 19 and the rotating shaft 21. The limit rods 22 are located at the lower side of the center of the rotating shaft 21. An L-shaped rod 23 is slidably connected to the side wall of the connecting plate 18. The limit rod 22 is horizontally fixedly connected to the horizontal section of the L-shaped rod 23. The upper end of the L-shaped rod 23 is fixedly connected to a push rod 56. An inverted L-shaped plate 24 is fixedly connected to the positioning plate 9. The horizontal section of the L-shaped plate 24 cooperates with the transport plate 19.

[0072] The bottom of the groove 20 and the side opposite to the rotating shaft 21 are both open, and a torsion spring is sleeved on the rotating shaft 21, and the two ends of the torsion spring are respectively fixed on the fixed block and the rotating shaft 21. Through the rotational force of the torsion spring, the transport plate 19 is in a horizontal state, that is, the transport plate 19 and the connecting plate 18 are in an "L" shape, wherein the horizontal section of the L-shaped plate 24 is a permanent magnet, and the material of the transport plate 19 is metal. When the conveyor belt 2 drives the transport plate 19 to move below the horizontal section of the L-shaped plate 24, the horizontal section of the L-shaped plate 24, that is, the permanent magnet part, is adsorbed on the upper surface of the transport plate 19, and when the conveyor belt 2 continues to drive the transport plate 19 to move, the transport plate 19 drives the L-shaped plate 24 to move forward, thereby realizing the transportation of the positioning device.

[0073] In addition, the side walls of the rotating shaft 21 and the transport plate 19 are both provided with insertion holes for inserting the limit rod 22, and the limit rod 22 is inserted in the insertion holes. In the process of the transport plate 19 transporting the positioning device, the transport plate 19 is restricted by the limit rod 22, thereby preventing the end of the transport plate 19 away from the rotating shaft 21 from rotating downward due to gravity. A sliding groove is provided on the side wall of the connecting plate 18, and a slider is fixedly connected to the push rod 56. The slider is slidably connected in the sliding groove, and a spring is arranged between the slider and the side wall of the sliding groove. The spring is used to push the slider to slide and drive the push rod 56 to move, thereby facilitating the restoration of the position of the push rod 56, the L-shaped rod 23 and the limit rod 22.

[0074] The lower end and the top of the mobile frame 1 are fixedly connected with mutually perpendicular card plates 27, and a strip through hole 28 is provided at the bottom of the card plate 27. The end of the horizontal section of the L-shaped plate 24 is fixedly connected with a limit block 29, and the limit block 29 is inserted into the strip through hole 28 and slides horizontally in the strip through hole 28; a notch 30 for inserting the card plate 27 is provided on the side wall of the card plate 27 at the top of the mobile frame 1, and a stopper 31 is fixedly connected to the top of the notch 30, and the stopper 31 cooperates with the push rod 56; a symmetrically arranged second electric telescopic rod 25 is fixedly connected to the top of the mobile frame 1, and an L-shaped pull plate 26 is fixedly connected to the lower end of the second electric telescopic rod 25, and the horizontal section of the L-shaped pull plate 26 cooperates with the horizontal section of the L-shaped plate 24.

[0075] The two card plates 27 are perpendicular to each other and are in an "L" shape, and the card plates 27 are in a "U" shape. The opening of the card plates 27 is arranged opposite to the positioning device, wherein the top and the side of the end of the horizontally placed card plate 27 close to the first covering plate 3 are both open. Since the limit block 29 is inserted into the strip-shaped through hole 28, the position of the limit block 29 remains unchanged during the forward movement of the movable frame 1, that is, the position of the positioning device remains unchanged. When the movable frame 1 moves, causing the limit block 29 to be located at the position where the top and the side of the card plate 27 are in an open state, the second electric telescopic rod 25 is started at this time, and the lower end of the second electric telescopic rod 25 pushes the L-shaped pull plate 26 downward, so that the horizontal section of the L-shaped pull plate 26 is located below the horizontal section of the L-shaped plate 24. Since the second electric telescopic rod 25 is fixed to the top of the movable frame 1, the second electric telescopic rod 25 and the L-shaped pull plate 26 are driven to move forward during the forward movement of the movable frame 1. When the movable frame 1 drives the L-shaped pull plate 26 When the horizontal section of the L-shaped plate 24 moves to the bottom of the horizontal section of the L-shaped plate 24, the second electric telescopic rod 25 is started, and the second electric telescopic rod 25 pulls the L-shaped pull plate 26 upward. Since the horizontal section of the L-shaped pull plate 26 is located under the horizontal section of the L-shaped plate 24, the L-shaped plate 24 is pulled upward during the upward movement of the L-shaped pull plate 26, driving the arc-shaped bearing plate 4 and the limit plate 6 to move upward, wherein the width value of the limit block 29 is greater than the width value of the L-shaped plate 24, and the width value of the opening end of the vertical card plate 27 is less than the width value between the two opposite inner walls of the card plate 27, that is, the cross-section of the internal space of the vertical card plate 27 is a "convex" shape, thereby preventing the L-shaped plate 24 from detaching from the card plate 27 during the process of sliding downward through the card plate 27. At the same time, the horizontal section of the L-shaped plate 24 is blocked by the top of the card plate 27 in the horizontal state, which facilitates the first electric telescopic rod 12 to push the storage box 5 downward, thereby facilitating the insertion of the positioning nail 8 into the soil at the bottom of the groove.

[0076] When the conveyor belt 2 drives the connecting plate 18 and the transport plate 19 to move to the bottom of the horizontal section of the L-shaped plate 24, and the lower surface of the transport plate 19 contacts the lower surface of the horizontal section of the L-shaped plate 24, the conveyor belt 2 drives the connecting plate 18 and the transport plate 19 to move forward, and moves the connecting plate 18 forward and pushes the L-shaped plate 24 to one side of the L-shaped pull plate 26. When the L-shaped plate 24 is separated from the horizontal section of the L-shaped pull plate 26, the horizontal section of the L-shaped plate 24 is located on the transport plate 19. Due to the restriction of the limit rod 22 on the transport plate 19, the transport plate 19 is prevented from rotating downward away from one end of the connecting plate 18 during the transportation of the positioning device, thereby facilitating the pulling up and moving forward of the positioning device on the lower side of the installed and fixed pipeline, thereby facilitating the recycling of the positioning device.

[0077] The end surface of the stopper 31 opposite to the connecting plate 18 is inclined. When the conveyor belt 2 transports the L-shaped plate 24 to the vertical card plate 27 through the transport plate 19, the end of the push rod 56 contacts the inclined surface of the stopper 31. As the conveyor belt 2 drives the connecting plate 18 to continue to move, the push rod 56 is pushed by the inclined surface of the stopper 31, so that the push rod 56 drives the L-shaped rod 23 and the limit rod 22 to move away from the transport plate 19. When the limit rod 22 is separated from the transport plate 19, At this time, due to the gravity of the positioning component, the transport plate 19 rotates downward away from one end of the connecting plate 18, and the L-shaped plate 24 slides up and down through the transport plate 19, and slides down through the slot on the vertical card plate 27 to the horizontal card plate 27. Due to the cooperation between the slot on the card plate 27 and the limit block 29, the L-shaped plate 24 is prevented from detaching from the card plate 27 during the process of sliding downward through the vertical card plate 27, thereby realizing the transportation and recycling of the positioning equipment.

[0078] A strip groove 54 is provided on the inner arc wall of the arc-shaped supporting plate 4, and a ball 55 is rotatably connected in the strip groove 54; an arc-shaped supporting plate 32 is provided on the lower side of the arc-shaped supporting plate 4, and the arc-shaped supporting plate 32 is arranged between the two storage boxes 5, and the arc length of the arc-shaped supporting plate 32 is smaller than the arc length of the arc-shaped supporting plate 4; strip limiting grooves 33 are provided on the outer arc walls of the arc-shaped supporting plate 4 and the arc-shaped supporting plate 32, and a sliding block 34 is provided in the strip limiting groove 33, and the sliding block 34 is fixedly connected to the outer wall of the storage box 5.

[0079] The sliding block 34 is a horizontally arranged "T" shape, the width of the open end of the strip groove 54 is smaller than the width of the inner wall of the strip groove 54, the sliding block 34 is clamped in the strip groove 54, and multiple sliding blocks 34 are slidably connected with the arc-shaped supporting plate 4 and the arc-shaped supporting plate 32 through the strip groove 54. In the process of the arc-shaped supporting plate 4 and the arc-shaped supporting plate 32 rotating to both sides, the arc-shaped supporting plate 4 and the arc-shaped supporting plate 32 can be effectively prevented from detaching from the storage box 5.

[0080] During the process of installing the pipeline, the pipeline to be installed is lifted from the pipeline transport vehicle by means of a crane or other equipment in the prior art and transferred to the arc-shaped supporting plate 4. Since the height of the arc-shaped supporting plate 4 is adjusted, the height value of the pipeline to be installed placed on the arc-shaped supporting plate 4 is consistent with that of the already installed pipeline. At this time, the staff needs to push the pipeline to be installed on the arc-shaped supporting plate 4 toward the direction of the already installed pipeline. The rolling of the ball 55 reduces the resistance of the arc-shaped supporting plate 4 to the movement of the pipeline when installing the pipeline, thereby facilitating the installation of the pipeline by the staff.

[0081] The two storage boxes 5 are respectively fixedly connected with a second drive motor 35 and a third drive motor 39; the second drive motor 35 is located in one of the storage boxes 5, and a gear 36 is fixedly connected to the output shaft of the second drive motor 35, and a trapezoidal block 40 is threadedly connected to the output shaft of the second drive motor 35, and the trapezoidal block 40 is slidably connected to the inner wall of the storage box 5, and an L-shaped plug plate 41 is provided on one side of the second drive motor 35, and the trapezoidal block 40 cooperates with the vertical section of the L-shaped plug plate 41, and the small end of the trapezoidal block 40 is close to the L-shaped plug plate 41, and the horizontal section of the L-shaped plug plate 41 passes through the side wall of the storage box 5 and is inserted on the outer arc wall of the arc-shaped support plate 32, and the L-shaped plug plate 41 is connected to the storage box 5. A first spring 42 is arranged between the inner walls of the material box 5; the third drive motor 39 is fixed on the outer side wall of another material storage box 5, and a rotating rod 43 is fixedly connected to the output shaft of the third drive motor 39, the rotating rod 43 is rotatably connected to the material storage box 5, and a gear 36 is fixedly connected to the rotating rod 43; a plurality of strip grooves 37 are opened on the outer arc wall of the arc-shaped supporting plate 4, and a plurality of meshing teeth 38 are arranged on the outer arc wall of the arc-shaped supporting plate 4 and the inner arc wall of the arc-shaped supporting plate 32, the meshing teeth 38 are located in the strip grooves 37, and the meshing teeth 38 are meshed with the gear 36, the second drive motor 35 drives the arc-shaped supporting plate 4 to rotate, and the third drive motor 39 drives the arc-shaped supporting plate 32 to rotate.

[0082] The second drive motor 35 is fixedly connected to the inner wall of the storage box 5, and a through hole for the gear 36 and the L-shaped plug plate 41 to pass through is opened on the outer wall of the storage box 5 with the second drive motor 35 inside. The gear 36 passes through the through hole and meshes with the meshing teeth 38 on the arc-shaped supporting plate 4. A strip plug hole is opened on the outer arc wall of the arc support plate 32. The horizontal section of the L-shaped plug plate 41 passes through the through hole and is inserted into the strip plug hole on the arc support plate 32. The arc support plate 32 can support the arc support plate 4, thereby preventing the end of the arc support plate 4 away from the second drive motor 35 from sliding downward due to gravity when the pipeline is placed on the arc support plate 4. At the same time, the L-shaped plug plate 41 fixes the end of the arc support plate 32 away from the third drive motor 39 to prevent the end of the arc support plate 32 away from the third drive motor 39 from sliding downward, thereby realizing the arc support plate 4 supporting the pipeline.

[0083] A symmetrically arranged fixed block is fixedly connected to the outer wall of one of the storage boxes 5, and the third drive motor 39 is fixedly connected to the fixed block. The output shaft of the third drive motor 39 passes through the fixed block and is fixedly connected to the end of the rotating rod 43, and the end of the rotating rod 43 is rotatably connected to the fixed block.

[0084] When the lower side of the installed pipe is filled with soil, the second drive motor 35 is started, and the output shaft of the second drive motor 35 drives the gear 36 to rotate. During the rotation, the gear 36 drives the end of the arc-shaped supporting plate 4 close to the second drive motor 35 to rotate upward through the engagement with the meshing tooth 38, and the end of the arc-shaped supporting plate 4 close to the third drive motor 39 rotates downward, so that the arc-shaped supporting plate 4 rotates from the lower side of the installed pipe to the upper side of the pipe. When the end of the strip groove 54 on the arc-shaped supporting plate 4 contacts the sliding block 34, the arc-shaped supporting plate 4 rotates to the upper side of the pipe.

[0085] Since the trapezoidal block 40 is slidably connected to the inner wall of the storage box 5, the trapezoidal block 40 can be prevented from rotating with the rotation of the output shaft of the second drive motor 35. When the output shaft of the second drive motor 35 rotates, the second drive motor 35 screws out the trapezoidal block 40 through the thread, and the trapezoidal block 40 moves between the vertical section of the L-shaped plug plate 41 and the inner wall of the storage box 5. The inclined surface of the trapezoidal block 40 pushes the vertical section of the L-shaped plug plate 41 so that the L-shaped plug plate 41 moves in a direction away from the arc-shaped support plate 32, thereby facilitating the arc-shaped support plate 32 to separate from the arc-shaped support plate 32, wherein a threaded rod is fixedly connected to the output shaft of the second drive motor 35, and a nut is fixedly connected to the trapezoidal block 40. When the horizontal section of the L-shaped plug plate 41 separates from the arc-shaped support plate 32, the end of the internal thread on the nut contacts the end of the external thread on the threaded rod, and the inclined surface of the trapezoidal block 40 is located between the vertical section of the L-shaped plug plate 41 and the inner wall of the storage box 5.

[0086] When the arc-shaped supporting plate 4 rotates to the top of the pipeline and the L-shaped plug plate 41 is separated from the arc-shaped supporting plate 32, the third driving motor 39 is started at this time, and the output shaft of the third driving motor 39 drives the rotating rod 43 and the gear 36 to rotate. The gear 36 meshes with the meshing tooth 38 and drives the end of the arc-shaped supporting plate 32 close to the third driving motor 39 to rotate upward, and the end of the arc-shaped supporting plate 32 close to the second driving motor 35 rotates upward through the lower side of the pipeline to the upper side of the pipeline, so as to facilitate the positioning device to be pulled up through the lower side of the pipeline, and facilitate the recycling of the positioning device.

[0087] A baffle plate 44 is provided on one side of the feed hopper 10 away from the conveyor belt 2. The baffle plate 44 is higher than the feed hopper 10 and is used to prevent soil at the upper end of the feed hopper 10 from falling onto the arc-shaped supporting plate 4. A placement plate 45 is horizontally fixedly connected to the upper end surface of the feed hopper 10, and the placement plate 45 is close to the conveyor belt 2.

[0088] When in use, the positioning component is conveyed to the groove where the pipe needs to be installed by the conveyor belt 2. During the installation of the positioning component, the positioning component is close to the side wall of the groove where the pipe is installed, and the placement plate 45 is located on the ground on both sides of the groove and fits with the ground. Not only can the positioning equipment be installed, but it is also convenient for the second covering plate 14 to push the soil on the ground on both sides of the groove into the feed funnel 10 through the placement plate 45, so as to facilitate the soil to slide down through the feed funnel 10 and the discharge pipe 11 into the groove for installing the pipe.

[0089] Working principle: during use, the mobile frame 1 is placed above the groove for installing the pipeline, and the four corners of the mobile frame 1 are located on the ground on both sides of the groove, and the mobile frame 1 is connected to the pipeline transport vehicle by existing equipment such as ropes. As the pipeline transport vehicle moves forward with the progress of pipeline installation, the mobile frame 1 is driven to move in the forward direction of the pipeline installation, and then the storage boxes 5 on both sides of the arc-shaped supporting plate 4 are fixed near the bottom of the groove, and the storage boxes 5 are close to the side walls of the groove, and the limit blocks 29 are inserted into the strip through holes 28, and the first electric telescopic rod 12 is started. The first electric telescopic rod 12 pushes the storage box 5 downward, and pushes the storage box 5 downward, and at the same time pushes the positioning nail 8 downward, so that the positioning nail 8 is inserted into the soil at the bottom of the groove, and at the same time, through the laser level or projection in the prior art. The height of the arc-shaped supporting plate 4 is detected by a line meter. When the height value of the inner arc wall of the installed arc-shaped supporting plate 4 is inconsistent with the bottom height value of the outer arc wall of the installed pipe, the first electric telescopic rod 12 is started to drive the storage box 5 to move upward or downward, and at the same time drive the arc-shaped supporting plate 4 to move upward or downward, so as to adjust the height of the inner arc wall of the arc-shaped supporting plate 4 according to the bottom of the installed outer wall of the pipe, so as to facilitate the control of the installation height of the pipe and facilitate the installed pipes to be in the same horizontal plane. In the process of placing the pipe on the arc-shaped supporting plate 4 for installation, the two sides of the arc-shaped supporting plate 4 block the pipe, thereby preventing the pipe from rolling to both sides during the installation process, thereby ensuring that the interface parts of the two pipes are relative during the installation process, thereby improving the installation efficiency of the pipe.

[0090] The pipe to be installed is then placed on the arc-shaped supporting plate 4, and the pipe on the arc-shaped supporting plate 4 is pushed to one side by existing mechanical equipment. In the process of pushing the pipe, the ball 55 rolls on the arc-shaped supporting plate 4, thereby reducing the resistance of the arc-shaped supporting plate 4 to the pipe, thereby facilitating the installation and splicing of the pipe.

[0091] During the intermittent forward movement of the pipeline transport vehicle, the pipeline transport vehicle pulls the mobile frame 1 forward. When the mobile frame 1 drives the second electric telescopic rod 25, the L-shaped pull plate 26, the second covering plate 14, and the first covering plate 3 to move in the forward direction of the pipeline installation, the second covering plate 14 pushes the soil on the ground on both sides of the pipeline installation groove into the groove and the feed funnel 10, and the soil in the feed funnel 10 falls downward through the discharge pipe 11 to one side of the filling component. The filling component is started, and the filling component pushes the soil to the bottom of the pipeline, thereby filling the bottom of the pipeline and supporting the bottom of the pipeline by the soil to prevent the bottom of the pipeline from being suspended or collapsed.

[0092] When the horizontal section of the L-shaped pull plate 26 moves to the position directly below the horizontal section of the L-shaped plate 24, the second electric telescopic rod 25 is started, and the second electric telescopic rod 25 pulls the L-shaped plate 24 upward, and the first electric telescopic rod 12 is started at the same time, and the first electric telescopic rod 12 pulls the storage box 5 upward, and at the same time drives the positioning nail 8 to move upward, so that the positioning nail 8 is pulled out of the soil. When the positioning nail 8 is located above the ground on both sides of the installation pipeline groove, the first drive motor 17 is started at this time, and the output shaft of the first drive motor 17 passes through the rotating shaft 15, the pulley 16 drives the conveyor belt 2 to rotate, when the conveyor belt 2 drives the connecting plate 18 and the transport plate 19 to move, when the conveyor belt 2 drives the connecting plate 18 and the transport plate 19 to move to the bottom of the horizontal section of the L-shaped plate 24 and the lower surface of the transport plate 19 contacts the lower surface of the horizontal section of the L-shaped plate 24, at this time, the conveyor belt 2 drives the connecting plate 18 and the transport plate 19 to move forward, and moves the connecting plate 18 forward and pushes the L-shaped plate 24 to one side of the L-shaped pull plate 26. When the L-shaped plate 24 is separated from the horizontal section of the L-shaped pull plate 26, at this time, the L-shaped plate 24 The horizontal section is located on the transport plate 19, and the conveyor belt 2 drives the connecting plate 18, the transport plate 19 and the L-shaped plate 24 to move toward the vertical card plate 27, that is, the positioning device is moved toward the forward direction of the pipeline installation through the conveyor belt 2 through the transport plate 19. When the push rod 56 on the transport plate 19 contacts the stopper 31, the limit block 29 moves into the vertical card plate 27 through the notch 30. At the same time, the stopper 31 pushes the push rod 56 to push the limit rod 22 away from the transport plate 19. At this time, the transport plate 19 is away from one end of the connecting plate 18. The L-shaped plate 24 slides downward through the inclined transport plate 19. When the L-shaped plate 24 is separated from the transport plate 19, the rotational force of the torsion spring on the rotating shaft 21 causes the transport plate 19 to rotate to a horizontal state. When the push rod 56 is separated from the block 31, the spring pushes the limit rod 22 toward the transport plate 19 through the slider and the push rod 56 through the elastic force of the spring, so that the limit rod 22 is inserted into the jack on the rotating shaft 21 and the transport plate 19, thereby facilitating the restoration of the positions of the transport plate 19 and the limit rod 22.

[0093] In the process of transporting the positioning device, the third drive motor 39 is started, and the third drive motor 39 drives the rotating rod 43 and the gear 36 on the rotating rod 43 to rotate in the opposite direction, and the gear 36 is meshed with the meshing teeth 38 on the arc-shaped support plate 32, thereby driving the lower end of the arc-shaped support plate 32 to rotate downward, so that the opening of the arc-shaped support plate 32 is set upward, and then the second drive motor 35 is started, and the second drive motor 35 drives the gear 36 to rotate in the opposite direction, and the meshing teeth 38 on the gear 36 and the arc-shaped support plate 4 drive the arc-shaped support plate 4 to rotate downward. When the position of the arc-shaped support plate 4 is restored, and in the process of the reverse rotation of the gear 36, the first spring 42 is pressed against the L-shaped plug The plate 41 pushes, so that the L-shaped plug plate 41 pushes the inclined surface of the trapezoidal block 40, so that the internal thread on the nut on the trapezoidal block 40 is engaged with the external thread on the threaded rod on the second drive motor 35. In the process of the second drive motor 35 driving the gear 36 to rotate in the opposite direction, the trapezoidal block 40 moves in the direction of the second drive motor 35 through the engagement of the threads. At this time, the trapezoidal block 40 withdraws from between the L-shaped plug plate 41 and the inner wall of the storage box 5, so that the horizontal section of the L-shaped plug plate 41 is inserted into the arc support plate 32, thereby fixing the position of the arc support plate 32, and lifting the arc support plate 4 by the arc support plate 32, thereby improving the bearing capacity of the arc support plate 4.

[0094] When the positioning device slides down into the horizontal card plate 27, the limit block 29 is inserted into the bar-shaped through hole 28 on the card plate 27. When the mobile frame 1 continues to move forward, the L-shaped plate 24 is inserted into the horizontal card plate 27, and the upper surface of the L-shaped plate 24 contacts the top of the horizontal card plate 27. The limit block 29 is restricted by the bar-shaped through hole 28, thereby preventing the positioning device from tipping into the groove of the installation pipe and fixing the position of the positioning device.

[0095] While the mobile frame 1 moves in the forward direction of the pipeline installation, the second covering plate 14 scrapes the soil on the ground into the groove, and part of the soil falls into the feed funnel 10, so that the filling component pushes the soil sliding down in the feed funnel 10 to the bottom of the installed pipeline, thereby filling the bottom of the pipeline and supporting the pipeline with the filled soil. During the movement, the first covering plate 3 pushes the soil into the groove where the pipeline has been installed and the positioning device has been pulled out, thereby achieving the covering of the installed pipeline by the soil.

[0096] Embodiment 2

[0097] The following technical features are added on the basis of the first embodiment:

[0098] A municipal pipeline construction device, the filling components include: a third electric telescopic rod 46, the third electric telescopic rod 46 is horizontally fixedly connected to the limit plate 6; a push plate 47, the push plate 47 is fixedly connected to the moving end of the third electric telescopic rod 46; a limiting plate 48, the limiting plate 48 is fixedly connected to the upper end surface of the pushing plate 47, the limiting plate 48 cooperates with the discharge pipe 11, and the length of the limiting plate 48 is consistent with the extended length of the moving end of the third electric telescopic rod 46.

[0099] When the third electric telescopic rod 46 pushes the soil to the bottom of the installed pipe through the pushing plate 47, the upper surface of the limiting plate 48 contacts the lower end surface of the discharge pipe 11, thereby closing the lower end of the discharge pipe 11. When the third electric telescopic rod 46 fills the soil under the pipe through the pushing plate 47, the soil in the discharge pipe 11 is prevented from continuing to fall downward.

[0100] A telescopic tube 49 is fixedly connected to the side wall of the material storage box 5 , and the upper end of the telescopic tube 49 is fixedly connected to the discharge pipe 11 , and the material storage box 5 is connected to the discharge pipe 11 through the telescopic tube 49 .

[0101] The telescopic tube 49 facilitates the material storage box 5 to move up and down as the first electric telescopic rod 12 pushes or pulls, and also facilitates the soil in the discharge pipe 11 to slide into the material storage box 5 through the telescopic tube 49 .

[0102] The bottom of the storage box 5 is tilted, and a discharge port 50 is opened on the side wall of the storage box 5. A cover plate 51 that moves up and down is inserted at the bottom of the discharge port 50, and a second spring 52 is arranged between the cover plate 51 and the top of the discharge port 50; a baffle rod 53 is fixedly connected to the side wall of the cover plate 51, the baffle rod 53 on the lower side of the second drive motor 35 cooperates with the arc-shaped supporting plate 4, and the baffle rod 53 on the lower side of the third drive motor 39 cooperates with the arc-shaped support plate 32.

[0103] The bottom of the storage box 5 is arranged at an angle to facilitate the soil in the storage box 5 to slide down the inclined surface of the bottom of the storage box 5, and a partition is arranged at the bottom of the second drive motor 35, and the partition is in an "L" shape. The upper end of the partition is fixedly connected to the top of the storage box 5, and the horizontal section of the partition is fixed on the inner wall of the storage box 5. The partition can effectively prevent the soil in the storage box 5 from accumulating upward and affecting the normal operation of the second drive motor 35, wherein a rectangular arc-shaped notch is opened at one end of the arc-shaped support plate 32 close to the second drive motor 35, and the baffle rod 53 on the lower side of the second drive motor 35 passes through the arc-shaped notch and contacts the outer arc wall of the arc-shaped supporting plate 4.

[0104] A receiving groove for receiving the groove cover plate 51 is opened at the top of the discharge port 50, and the second spring 52 is located between the cover plate 51 and the top of the receiving groove, and a strip hole for the up and down movement of the blocking rod 53 is opened on the side wall of the receiving groove, so that the second spring 52 can pull the cover plate 51 upward into the receiving groove, thereby facilitating the opening of the discharge port 50.

[0105] Working principle: when the pipe installation and splicing on the arc-shaped bearing plate 4 is completed, the third electric telescopic rod 46 is started, and the third electric telescopic rod 46 pulls the limiting plate 48 away from the lower port of the discharge pipe 11, and the lower port of the discharge pipe 11 is in an open state. At this time, the discharge pipe 11 and the soil stored in the feeding funnel 10 slide downward through the discharge pipe 11 to one side of the pushing plate 47. At this time, the third electric telescopic rod 46 is started again, and the third electric telescopic rod 46 pushes the pushing plate 47 to the bottom of the pipe, thereby pushing the pushing plate 47 away from the soil on one side of the third electric telescopic rod 46 to the bottom of the pipe. In the process of the third electric telescopic rod 46 pushing the pushing plate 47 to the bottom of the pipe, the limiting plate 48 is driven to move horizontally. When the upper surface of the limiting plate 48 is aligned with the discharge pipe 11, the pushing plate 47 is pushed downward to the bottom of the pipe. When the lower ends are in contact, the lower end of the discharge pipe 11 is in a closed state, thereby preventing the soil from continuously falling through the discharge pipe 11. When the third electric telescopic rod 46 pulls back the push plate 47 and causes the limiting plate 48 to detach from the discharge pipe 11, the soil in the discharge pipe 11 continues to slide downward, thereby causing the third electric telescopic rod 46 to continuously push the soil to the bottom of the pipe, causing the soil to accumulate under the pipe and the arc-shaped support plate 32. Since the third electric telescopic rods 46 on both sides of the pipe simultaneously push the soil to the bottom of the pipe through the push plates 47, the two push plates 47 continuously push the soil pushed under the pipe and compact the soil under the pipe and the arc-shaped support plate 32, thereby facilitating the soil under the pipe to support the pipe.

[0106] When the soil under the pipeline is compacted and can support the pipeline, the second drive motor 35 is started at this time to drive the arc-shaped supporting plate 4 to rotate upward through the meshing of the gear 36 and the meshing teeth 38. When the lower end of the arc-shaped supporting plate 4 disengages from the blocking rod 53 below the second drive motor 35, the second spring 52 pulls the cover plate 51 upward through the elastic force of the second spring 52. At this time, the discharge port 50 is in an open state, and the soil stored in the storage box 5 slides down the inclined surface at the bottom of the storage box 5, and part of the soil slides into the gap between the arc-shaped supporting plate 32 and the pipeline, and then the third drive motor 39 is started. The third drive motor 39 drives the arc-shaped supporting plate 32 to rotate upward through the meshing of the gear 36 and the meshing teeth 38. In the process of the arc-shaped supporting plate 32 rotating upward, when the arc-shaped supporting plate 32 is close to the third drive motor 39, the arc-shaped supporting plate 32 is in a state of being opened. When one end of the second drive motor 35 rotates to the bottom of the pipeline, the soil that falls on the arc support plate 32 slides downward through the lower end of the arc support plate 32 to the gap left when the arc support plate 32 and the arc supporting plate 4 move away from the bottom of the pipeline, thereby filling the gap under the pipeline, further improving the supporting effect of the soil on the pipeline, and when the lower end of the arc support plate 32 is separated from the baffle 53 under the third drive motor 39, the elastic force of the second spring 52 causes the second spring 52 to pull the cover plate 51 under the arc support plate 32 upward, thereby opening the discharge port 50 near the arc support plate 32, thereby facilitating the soil in the storage box 5 and the soil in the discharge pipeline 11 to slide to the bottom of the pipeline through the telescopic tube 49 and the storage box 5, and fill the gap under the pipeline again.

[0107] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
