[0038] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0039] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be applied to other embodiments, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

[0040] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0041] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, and in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the number.

[0042] Such as Figures 1-3As shown in the figure, a precise positioning device for the installation of small hydraulic longitudinal beams according to the present invention includes a base 1, adjusting wheels (a transverse adjusting wheel 3 and a longitudinal adjusting wheel 4), and an elevation adjusting part. A plurality of adjusting wheels are installed on the upper surface of the base 1, the surface of the adjusting wheels protrudes from the surface of the base 1, the adjusting wheels are rotatable, the elevation adjusting part is installed on the base 1, and the height of the elevation adjusting part is adjustable. The top of the elevation adjusting part receives the beam slab. A mark 2 is provided on the side of the base, generally a triangular mark.

[0043] In the above technical solution, during the actual use of the positioning device, first place the base at the construction position to ensure the levelness of the base. Then, according to the designed position of the longitudinal beam, adjust the position and direction of the adjusting wheels so that they can accurately perform planar positioning on the longitudinal beam. Next, lift the longitudinal beam to the designed elevation through the elevation adjusting part to complete the installation and positioning of the longitudinal beam. The whole device has a simple structure and is easy to operate, which can effectively improve the installation accuracy and efficiency of small hydraulic longitudinal beams.

[0044] In another technical solution, a long strip-shaped card slot 5 is formed by the middle of the base 1 sinking downward, and the card slot 5 divides the base into a left part of the base and a right part of the base. This structural design enables the base to better adapt to the shape and size of the longitudinal beam, and at the same time provides an installation space for the elevation adjusting part.

[0045] The adjusting wheels are provided on both the left part of the base and the right part of the base. The adjusting wheels include a transverse adjusting wheel 3 and a longitudinal adjusting wheel 4. The rotation directions of the transverse adjusting wheel 3 and the longitudinal adjusting wheel 4 are perpendicular in the horizontal direction. It can realize the adjustment of the longitudinal beam in two mutually perpendicular directions. The transverse adjusting wheel is mainly used to adjust the left and right positions of the longitudinal beam, and the longitudinal adjusting wheel is used to adjust the front and back positions of the longitudinal beam. Through the coordinated action of the transverse adjusting wheel and the longitudinal adjusting wheel, the planar position of the longitudinal beam can be accurately controlled to ensure its consistency with the designed position.

[0046] In another technical solution, a lifting mechanism is provided at the bottom of the adjusting wheel, and the adjusting wheel realizes height adjustment as the lifting mechanism rises and falls.

[0047] In the above technical solution, during the installation of the longitudinal beam, first adjust the height of the adjusting wheel to the lowest position so that the adjusting wheel is flush with the surface of the base. Then place the longitudinal beam on the base, and through the telescopic action of the electric push rod, lift the adjusting wheel to make the adjusting wheel contact the longitudinal beam and be able to rotate freely. At this time, use the rotation function of the adjusting wheel to perform planar adjustment on the longitudinal beam until the longitudinal beam reaches the designed position.

[0048] By setting up a lifting mechanism, the height of the adjusting wheel can be flexibly adjusted according to the installation requirements of the longitudinal beam. After the longitudinal beam is installed, the height of the adjusting wheel can be lowered to make it flush with the base surface, avoiding interference with subsequent construction. This design not only improves the flexibility and adaptability of the longitudinal beam installation, but also enhances the versatility and practicality of the device.

[0049] In another technical solution, the elevation adjustment part is arranged in the clamping groove 5 of the base 1.

One end of the two is hinged through the lifting and rotating shaft 6, and the other ends are respectively connected to the adjustment panel 8 and the base groove 5. A horizontally arranged threaded hole is opened in the lifting and rotating shaft 6. The lifting adjustment rod 7 is threaded horizontally through the threaded holes of the two lifting and rotating shafts 6. By rotating the lifting adjustment rod 7, the relative distance between the two groups of connecting rod structures is adjusted, and then the height of the two groups of connecting rod structures is adjusted.

The longitudinal beam 13 is preset to be erected between the two cast-in-place cross beams 12; this step is the basis of the entire installation process, and accurate measurement can provide a reliable benchmark for subsequent installation.

[0052] S2. Install the precise positioning device 14 on the pile cap 11, and install the identifier 2 of the precise positioning device 14 corresponding to the lofting reference point on the pile cap 11 to ensure that the installation positions of the precise positioning device 14 and the longitudinal beam 13 are consistent; through the correspondence between the identifier and the reference point, the installation position of the device can be quickly determined, improving the installation efficiency.

[0053] S3. Place the longitudinal beam 13 preliminarily on the precise positioning device 14. At this time, the elevation adjustment part in the precise positioning device 14 is in the lowest state, and the adjustment panel 8 is not in the lifting state yet.

[0064] S42. Determine the design mileage L of any design point C on the temporary straight line from the origin and the design offset D 设计 and measure the actual coordinates (xa, ya) of the actual point C1 corresponding to the design point C. Then substitute the actual coordinate values of point C1 into Formula 2 and Formula 3 to calculate the actual mileage L 设计 of point C1 from the origin and the actual offset D 实际 . Among them, the calculation formulas for the actual mileage L 实际 and the offset D 实际 are respectively: 实际 Calculate the mileage deviation value ΔL and the offset deviation value ΔD
