[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-5 As shown, an inverted siphon pressure steel pipe 3 installation device includes an installation base 1, hydraulic lifting devices 2 located at each corner of the upper surface of the installation base 1, a pressure steel pipe 3, and several MEMS inertial sensors 4 located at the end face of the pressure steel pipe 3. The bottom of each hydraulic lifting device 2 is fixedly connected to the upper surface of the installation base 1. A support plate 5 is hinged to the upper end face of the hydraulic lifting device 2. A connecting column 6 is fixedly connected to each corner of the upper surface of the support plate 5. An installation plate 7 is fixedly connected to the upper end face of the connecting column 6. Two pairs of connecting frames 8 are symmetrically arranged on the installation plate 7 along the long side of the upper surface of the installation plate 7. A force transmission guide rod 9 is fixedly connected between two adjacent connecting frames 8 near the same long side of the upper surface of the installation plate 7. A connecting block 10 that is slidably connected to the installation base 1 is fixedly connected to the outer surface of the two force transmission guide rods 9. A metal arc-shaped bearing seat 11 with openings facing each other and used to support the outer bottom surface of the pressure steel pipe 3 is symmetrically arranged on the outer surface of the two connecting blocks 10 that are close to each other. An adjustment device for adjusting the distance between the two connecting blocks 10 is provided on the support plate 5.

[0026] The MEMS inertial sensors 4 consist of two sets, located on the two end faces of the pressure steel pipe 3 respectively.

[0027] The two metal arc-shaped bearing seats 11 are respectively hinged to the connecting block 10 on the same side;

[0028] The upper surface of each hydraulic lifting device 2 is spherically hinged to the bottom of the receiving plate 5.

[0029] The specific working process of the scheme is: fix the mounting base 1 at the preset mounting position, ensure that the base is horizontal and stable; check whether the hydraulic system of each hydraulic jacking device 2 is normal, whether the connection of the connecting column 6 with the receiving plate 5 and the mounting plate 7 is firm, and whether the surface of the metal arc-shaped bearing seat 11 is flat and undamaged;

[0030] Further, the pressure steel pipe 3 is slowly lifted by the lifting equipment and moved above the mounting device. The position of the steel pipe is adjusted so that the outer bottom surface of the steel pipe precisely fits the two metal arc-shaped bearing seats 11, and the gravity center of the steel pipe falls in the central area of the bearing seat, avoiding uneven stress on one side.

[0031] Then, the hydraulic jacking device 2 is started. According to the installation requirements, the lifting of the four hydraulic jacking devices 2 is controlled individually or synchronously to adjust the height and inclination angle of the receiving plate 5, thereby driving the mounting plate 7, the connecting frame 8, the force transmission guide rod 9 and the connecting block 10 to move synchronously, realizing the adjustment of the height and horizontal angle of the pressure steel pipe 3. In this process, the MEMS inertial sensor 4 at the two ends of the pressure steel pipe 3 collects posture data such as inclination angle and vibration frequency of the steel pipe in real time, and transmits the data to the control system. The operator adjusts the action of the hydraulic jacking device 2 according to the data feedback until the steel pipe reaches the preset installation posture.

[0032] When the posture of the steel pipe is adjusted in place, the hydraulic jacking device 2 is locked to prevent displacement during the subsequent installation process. Then, the pressure steel pipe 3 is fixed and connected according to the design requirements, and the butt joint installation with the adjacent pipeline or equipment is completed.

[0033] As shown in Figure 2 , the two connecting blocks 10 are further fixedly connected with magnetic blocks 20 on the outer surfaces close to each other, and the two magnetic blocks 20 are respectively attached to the outer surfaces of the same side metal arc-shaped bearing seat 11.

[0034] The purpose of the scheme is that during the adjustment of the distance between the connecting block 10 and the metal arc-shaped bearing seat 11 above, the magnetic blocks 20 on both sides can respectively adsorb the outer surfaces of the metal arc-shaped bearing seats 11 on both sides, so as to maintain the same inclination angle of the metal arc-shaped bearing seats 11 during lifting of the pressure steel pipe 3, make the two metal arc-shaped bearing seats 11 contact the outer surface of the pressure steel pipe 3 at the same time, avoid direct contact between a single metal arc-shaped bearing seat 11 and the outer surface of the pressure steel pipe 3, and cause uneven stress, which further causes serious indentation on the outer surface of the pressure steel pipe 3, thereby affecting the service life and installation effect of the pressure steel pipe 3.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjusting device comprises two symmetrically arranged first sliding grooves 12 parallel to the short edges of the upper surface of the receiving plate 5, a transmission gear 13 is rotatably connected to the upper surface of the receiving plate 5 and located between the two first sliding grooves 12, two transmission racks 14 engaged with the transmission gear 13 are slidably connected in the two first sliding grooves 12, two second sliding grooves 15 coinciding with the positions of the first sliding grooves 12 are symmetrically formed in the upper surface of the mounting plate 7, the upper surfaces of the two transmission racks 14 are fixedly connected with first receiving blocks 16 extending upward through the second sliding grooves 15, the upper surfaces of the first receiving blocks 16 are fixedly connected with the connecting blocks 10 on different sides respectively, the upper surface of the receiving plate 5 is further fixedly connected with an electric push rod 17 parallel to the first sliding grooves 12, and the extension end of the electric push rod 17 is fixedly connected with one of the transmission racks 14;

[0036] Second receiving blocks 18 are slidably connected in the groove bodies of the two second sliding grooves 15 on which the first receiving blocks 16 are not arranged, and the two second receiving blocks 18 are fixedly connected with the connecting blocks 10 above respectively;

[0037] Two third sliding grooves 19 parallel to the short edges are symmetrically arranged on the upper surface of the mounting plate 7 near the short edges, and the connecting frame 8 is located in and slidably connected with the third sliding grooves 19.

[0038] Further explanation of the scheme: Before mounting the pressure steel pipe 3, check the state of each component of the adjusting device to ensure that there is no foreign matter blocking in the first sliding grooves 12, the second sliding grooves 15 and the third sliding grooves 19, the transmission gear 13 is well engaged with the transmission rack 14, the electric push rod 17 has normal extension function, and the first receiving block 16 and the second receiving block 18 are firmly connected with the connecting block 10 and the transmission rack 14;

[0039] After completion, set the target distance of the connecting block 10 through the control system according to the outer diameter size of the pressure steel pipe 3 to be mounted; start the electric push rod 17, the extension end of the electric push rod 17 pushes the transmission rack 14 connected therewith to slide along the first sliding groove 12, since the transmission rack 14 is engaged with the transmission gear 13, the transmission rack 14 moves to drive the transmission gear 13 to rotate, thereby driving the transmission rack 14 on the other side to make reverse synchronous motion along the first sliding groove 12; the two transmission racks 14 drive the connecting blocks 10 above to move synchronously and reversely along the second sliding grooves 15 and the third sliding grooves 19 through the first receiving blocks 16 and the second receiving blocks 18 respectively, until the distance between the two connecting blocks 10 reaches the preset value matching the outer diameter of the steel pipe, and then the electric push rod 17 is turned off to lock the position of the transmission rack 14;

[0040] Then the pressure steel pipe 3 is placed on the metal arc-shaped bearing seat 11, if the steel pipe and the bearing seat are not close enough or there is a slight position deviation, the electric push rod 17 can be started again, the moving distance of the fine adjustment transmission rack 14 is adjusted, the spacing of the connecting blocks 10 is changed, the metal arc-shaped bearing seat 11 is better combined with the outer bottom surface of the steel pipe, and the stable lifting of the steel pipe is ensured; meanwhile, in the process of adjusting the spacing of the connecting blocks 10, the third sliding groove 19 precisely guides the movement of the connecting frame 8, so that the uneven force of the force transmission guide rod 9 caused by the deviation of the connecting frame 8 is avoided.

[0041] In addition, in the prior art, the sensing data is acquired by the MEMS inertial sensor 4, then the software system is used for calculation adjustment analysis, finally the analysis data is transmitted to the control system (or the PLC control system) of the hydraulic jacking device 2, finally the hydraulic jacking device 2 is adjusted to implement the jacking operation of a certain distance, in the above technical scheme, the software program part is not described in detail (wherein the MEMS inertial sensor 4 generally comprises a wireless transmission module, a power module, an inertial sensor and a single chip, and details are not described again; the PLC controller comprises an industrial computer, a wireless transmission module and a display, which are not the technical content protected by the utility model, and details are not described again).
