[0002] The municipal drainage network is an important municipal facility to ensure the normal living order of old urban communities, and it plays a vital role in the urbanization process. In recent years, the problems of the existing drainage network in old urban communities have gradually been exposed. Frequent backflow of sewer wells and poor drainage in the rainy season have seriously affected the daily life of the people. In order to improve the image and quality of the city and truly benefit the lives of the people, the planning and transformation of the existing drainage network in old urban communities cannot be delayed.

[0003] Traditional pipeline positioning and installation mainly rely on manual measurement and marking for positioning, and then the excavator is used with a sling to install and adjust the position.

Once the initial position of the clamping mechanism is determined, after measuring the three-dimensional coordinates of the positioning prism, the three-dimensional coordinates of the initial position of the clamping mechanism are also determined accordingly. After moving the device to the top of the initial placement position of the pipeline, the coordinates of the positioning prism are measured again, and the coordinates of the initial placement position of the pipeline can be determined accordingly. After the initial placement position and the design position of the pipeline are determined, the lateral position, longitudinal position and pitch angle of the pipeline can be adjusted by the transverse movement mechanism, the longitudinal movement mechanism and the lifting mechanisms to move the pipeline to the design position.

The lifting motor drives one of the lifting wheels to rotate, and then several lifting gears are raised or lowered in the corresponding lifting racks, the lifting platform as a whole rises or falls, the height of the corresponding part of the pipeline changes, and the pitch angle of the pipeline is accurately adjusted.

[0016] A method for accurately installing a rainwater and sewage pipe comprises the following steps:

[0017] S1: Initially place the rainwater and sewage pipes in the trench;

[0018] S2: Move the device to the position directly above the initially placed pipes by controlling the moving mechanism;

[0019] S3: Measure the position of the precise installation device on the pipeline by using the total station;

[0020] S4: Clamp the pipe by the clamping mechanism;

[0021] S5: Move the pipeline to the designed position by adjusting the transverse movement mechanism, longitudinal movement mechanism, lifting mechanism and steering mechanism.

[0022] The total station can measure the three-dimensional coordinates of the center of the positioning prism on the pipeline precision installation device, and then combine the geometric parameters of the pipeline precision installation device that have been strictly calibrated in advance to convert the coordinates of each component in the pipeline precision installation device. After moving the device to the top of the initial placement position of the pipeline, measure the coordinates of the positioning prism, and the coordinates of the initial placement position of the pipeline can be determined accordingly.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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 part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] like Figure 1 and Figure 2 As shown, the rainwater and sewage pipe precision installation device of this embodiment includes a support frame 1, a moving mechanism 2 for driving the support frame 1 to move and position is installed at the bottom of the support frame 1, a longitudinal beam 3 is arranged on the support frame 1, a transverse mechanism 4 is connected between the longitudinal beam 3 and the support frame 1, a longitudinal movement mechanism 5 is connected to the longitudinal beam 3, a lifting mechanism 6 is connected to the longitudinal movement mechanism 5, a steering mechanism 7 is connected to the output end of the lifting mechanism 6, and a clamping mechanism 8 for clamping the pipe is connected to the steering mechanism 7. A control device 9 is also included, and the control device 9 is electrically connected to the moving mechanism 2, the transverse movement mechanism 4, the longitudinal movement mechanism 5, the lifting mechanism 6, and the clamping mechanism 8 respectively.

[0038] The support frame 1 includes a square frame, the bottom of which is connected to four legs, the moving mechanism 2 is installed at the bottom of the legs, and the transverse mechanism 4 is connected to the crossbeam of the square frame. To ensure the stability of transverse movement, the transverse mechanisms 4 are installed between the crossbeams on both sides and the longitudinal beams 3, and the two transverse mechanisms 4 act synchronously.

[0039] The number of units composed of the longitudinal movement mechanism 5, the lifting mechanism 6, the steering mechanism 7 and the clamping mechanism 8 is two. The two clamping mechanisms 8 clamp the two sections of the pipeline respectively, and by controlling the lifting mechanism 6 connected to the clamping mechanism 8, the heights of the two ends of the pipeline are different, so that the pitch angle of the pipeline can be adjusted to meet the design requirements.

[0040] The steering mechanism 7 can be a bearing, a rotating motor, or a rotating cylinder, and its function is to rotate the clamping mechanism 8 to be perpendicular to the pipe, so as to facilitate the clamping mechanism 8 to accurately clamp the pipe. Since multiple clamping mechanisms 8 clamp the pipe at the same time, the steering mechanism 7 cannot twist the pipe to avoid motion interference.

[0041] Two positioning prisms 11 are also installed on the support frame 1. The two positioning prisms 11 can be installed at the diagonal positions of the support frame 1. A total station for measuring the three-dimensional coordinates of the positioning prism 11 is arranged on the groove. The total station can measure the three-dimensional coordinates of the center of the positioning prism 11 on the pipeline precision installation device, and then combine the geometric parameters of the pipeline precision installation device that have been strictly calibrated in advance to convert the coordinates of each component in the pipeline precision installation device. Once the initial position of the clamping mechanism 8 is determined, after measuring the three-dimensional coordinates of the positioning prism 11, the three-dimensional coordinates of the initial position of the clamping mechanism 8 are also determined accordingly. Alternatively, the control device 9 determines the positions of the transverse movement mechanism 4, the longitudinal movement mechanism 5, and the lifting mechanism 6 relative to the support frame 1, and determines the position of the clamping mechanism 8 relative to the support frame 1.

[0042] Move the device to the position directly above the initial placement position of the pipeline, and use the center line and one end of the pipeline with the clamping mechanism 8 as the positioning reference. The pipeline can also be aligned with other components as a reference. After the reference is aligned, the transverse coordinate and longitudinal coordinate of the pipeline can be determined. However, the pitch angle of the pipeline in the initial placement position cannot be determined. Several clamping mechanisms 8 can be raised and lowered to a position just touching the pipeline, and the pitch angle of the pipeline in the initial placement position can be determined by the relative position of the lifting mechanisms 6 on the two clamping mechanisms 8. After the initial placement position and the design position of the pipeline are determined, the control device 9 controls the transverse movement mechanism 4, the longitudinal movement mechanism 5 and the two lifting mechanisms 6 to adjust the transverse position, longitudinal position and pitch angle of the pipeline to move the pipeline to the design position.

[0043] After the clamping mechanism 8 of the present invention grabs the initially placed pipe, the lateral position of the pipe is adjusted by the lateral movement mechanism 4, the longitudinal position of the pipe is adjusted by the longitudinal movement mechanism 5, and the pitch angle of the pipe is adjusted by the lifting mechanisms 6 at both ends, so that the pipe can be moved to the designed position. The present invention can accurately adjust the lateral position, longitudinal position and pitch angle of the pipe, ensure the accuracy of pipe laying, and avoid excessive installation deviation.

[0044] Specifically, the mobile mechanism 2 includes a plurality of forward steering devices 21 installed at the bottom of the support frame 1, and the forward steering devices 21 are connected to the moving wheels 22, and a moving drive motor is installed on one of the forward steering devices 21, and the output end of the moving drive motor is connected to the moving wheel 22. The forward steering device 21 can control the direction of the moving wheel 22, and the moving drive motor can drive the moving wheel 22 forward or backward, so that the device of the present invention can move as a whole. A limiting device for limiting the moving wheel 22 can be provided on the moving drive motor, so that the moving wheel 22 is limited after moving into position, and the overall position of the device is ensured to be accurate.

[0045] Specifically, Figure 5 and Figure 6As shown, the transverse mechanism 4 includes a transverse motor 41, which is mounted on the longitudinal beam 3, and the output end of the transverse motor 41 is connected to a transverse gear 42, and a transverse rack 12 is provided on the transverse beam of the support frame 1, and the transverse gear 42 is meshed with the transverse rack 12. The transverse motor 41 can drive the transverse gear 42 to rotate, and the transverse gear 42 rolls on the transverse rack 12, driving the longitudinal beam 3 and the components connected thereto to move transversely as a whole, so as to ensure that the transverse position of the pipeline is accurately adjusted.

[0046] To ensure stability during transverse movement, a transverse slide groove 13 is provided on the transverse beam of the support frame 1, and a transverse slider 31 is fixed on the longitudinal beam 3, and the transverse slider 31 is sleeved in the transverse slide groove 13. The number of transverse sliders 31 can be two, and the two transverse movement sliders are respectively arranged on both sides of the transverse movement gear 42.

[0047] Specifically, Figure 3 and Figure 4 As shown, the longitudinal movement mechanism 5 includes a hanging platform 51, and the lifting mechanism 6 is installed on the lower side of the hanging platform 51. A longitudinal movement motor 52 is installed on the hanging platform 51, and the output end of the longitudinal movement motor 52 is connected to a longitudinal movement gear 53. A longitudinal movement rack 32 is provided on the longitudinal beam 3, and the longitudinal movement gear 53 is meshed with the longitudinal movement rack 32. The longitudinal movement motor 52 can drive the longitudinal movement gear 53 to rotate, and the longitudinal movement gear 53 rolls on the longitudinal movement rack 32, driving the hanging platform 51 to move longitudinally, so as to ensure that the longitudinal position of the pipeline is accurately adjusted.

[0048] In order to ensure the stability of longitudinal movement, a longitudinal slide groove 33 is provided on the lower side of the longitudinal beam 3, and a longitudinal slide block 54 is fixed on the hanging platform 51, and the longitudinal slide block 54 is sleeved in the longitudinal slide groove; the longitudinal gear 53 is located at the lower side of the longitudinal gear rack 32. The longitudinal slide block 54 is hung in the longitudinal slide groove 33 to support the hanging platform 51. The number of longitudinal slide blocks 54 can be two, and the two longitudinal slide blocks 54 are respectively arranged on both sides of the longitudinal gear 53.

[0049] Specifically, Figure 8 As shown, the lifting mechanism 6 includes a lifting platform 61 and two pairs of lifting racks 62. The lifting racks 62 are fixed below the longitudinal movement mechanism 5. The lifting platform 61 is rotatably connected with a lifting gear 63 meshing with the lifting racks 62. A lifting motor is also installed on the lifting platform 61. The output end of the lifting motor is connected to the rotating shaft of one of the lifting gears 63. When the lifting motor drives one of the lifting wheels to rotate, the lifting gears 63 are raised or lowered by the corresponding lifting racks 62, and the lifting platform 61 rises or falls as a whole. The height of the corresponding part of the pipeline changes, and the pitch angle of the pipeline is accurately adjusted. In order to ensure the smoothness of the lifting, the rotating shafts of the four lifting gears 63 can be driven by belts to ensure that the four gears rotate synchronously.

[0050] Specifically, Figure 7As shown, the clamping mechanism 8 includes a mounting rod 81, one end of which is connected to the steering mechanism 7, and a clamping motor 82 is installed at the other end of the mounting rod 81. The output end of the clamping motor 82 is connected to a clamping driving gear 83. The mounting rod 81 is also rotatably connected to a clamping driven gear 84 meshing with the clamping driving gear 83, and clamping claws 85 are fixed on both the clamping driving gear 83 and the clamping driven gear 84. The clamping motor 82 drives the clamping driving gear 83 to rotate, and the clamping driving gear 83 drives the clamping driven gear 84 to rotate in the opposite direction. The two clamping claws 85 rotate in the opposite direction under the drive of the clamping driving gear 83 and the clamping driven gear 84, and the clamping claws 85 can clamp or release the pipeline.

[0057] The total station can measure the three-dimensional coordinates of the center of the positioning prism 11 on the pipeline precision installation device, and then combine the geometric parameters of the pipeline precision installation device that have been strictly calibrated in advance to convert the coordinates of each component in the pipeline precision installation device.
