[0002] Prefabricated box culverts, also known as assembled box culverts, are prefabricated reinforced concrete box structures. They are prefabricated in factories and assembled on-site, primarily for projects requiring a short construction period. When transporting prefabricated box culverts to the site for installation, a precast concrete pad is typically poured on the ground to form the concrete foundation. The individual box culvert sections are then hoisted into position on the concrete foundation for assembly.

[0003] However, during the lifting process, it is difficult to precisely control the falling position of the box culvert components. In addition, the box culvert will shake during the lifting and falling process, and it cannot fall completely vertically. As a result, the position of the box culvert placed on the concrete foundation cannot be guaranteed to be completely aligned with the previous section of the box culvert. The position needs to be adjusted repeatedly with the help of manual crowbars to complete the positioning operation. This method of positioning is relatively cumbersome and the positioning accuracy is low due to manual control.

[0004] Therefore, an assembly type box culvert installation and positioning device is proposed. Utility Model Content

[0026] A second telescopic assembly is provided on the base 1, and the second telescopic assembly is telescopic along the length direction of the box culvert 17. The telescopic end of the second telescopic assembly is fixedly connected to the connecting seat 3; the connecting seat 3 is provided with a driving mechanism, and two second positioning plates 4 are provided at the output end of the driving mechanism. The driving mechanism is used to drive the two second positioning plates 4 to move closer to or away from each other along the width direction of the box culvert 17. At the same time, the driving mechanism is used to drive the two second positioning plates 4 to rotate around an axis perpendicular to the side wall of the box culvert 17. The sides of the two second positioning plates 4 facing away from each other are respectively connected to a plurality of first rollers 5, and the first rollers 5 are used to roll in contact with the inner wall of the box culvert 17 to be positioned;

[0027] The base 1 is placed on the inner bottom wall of the box culvert 17, and the two first positioning plates 2 are pressed against the two inner side walls of the box culvert 17 by the two first telescopic components; when the next section of the box culvert 17 is hoisted and positioned, the second telescopic component drives the two second positioning plates 4 to extend into the next section of the box culvert 17, and the driving mechanism drives the two second positioning plates 4 to move away from each other synchronously, so that the first rollers 5 on the two second positioning plates 4 respectively roll in contact with the two inner side walls of the next section of the box culvert 17, and the next section of the box culvert 17 is positioned and guided so that the two sides of the next section of the box culvert 17 are aligned with the two sides of the previous section of the box culvert 17, and at the same time, the box culvert 17 is moved vertically downward or horizontally to avoid shaking during the movement, so as to facilitate docking with the first section of the box culvert 17, improve the positioning accuracy of the next section of the box culvert 17, and reduce the difficulty of operation.
