Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] This embodiment provides a bridge pile foundation reinforcement cage installation and positioning device, such as Figures 1 to 2 As shown, it includes a positioning frame 1 and a lifting mechanism 2;

[0027] The hoisting mechanism 2 includes a hoisting plate 21 provided with a vertical through-hole plate 211, and a hoisting member connected to the hoisting plate 21 through the vertical through-hole plate 211 for hoisting the steel cage into the steel casing;

[0028] Specifically, if Figures 3 and 4 As shown, the hoisting mechanism 2 and the positioning base 11 are both square structures; and the vertical through-hole plates 211 are respectively arranged on the hoisting plates 21 on the straight line where the diagonal line of the hoisting mechanism 2 is located, that is, arranged at the four right angles of the square structure;

[0029] The lifting components include a lifting ring, a lifting hook, and a lifting rope connected to the lifting ring;

[0030] The vertical through-hole plate 211 includes two ends of the hanging plate 21, the lifting ring is connected to the vertical through-hole plate 211, and the lifting rope connected to the lifting ring at the bottom end of the hanging plate 21 is provided with a hook for hanging the steel cage; the lifting rope on the upper side of the hanging plate 21 is installed on the hook of the crane, and the four corners of the lower side of the hanging plate 21 are connected to the steel cage through the hooks connected by the lifting ropes. The crane lifts the steel cage through the lifting mechanism 2, and the lifting mechanism 2 can ensure that the center of gravity of the hook and the hanging plate and the center of gravity of the steel cage are always consistent during the installation of the steel cage;

[0031] The positioning frame 1 is set on the ground outside the steel casing in the preset pile foundation hole. The top surface of the positioning frame 1 is higher than the top surface of the steel casing. The positioning frame 1 includes a positioning base 11, a plurality of guide mechanisms 12 and a plurality of positioning support plates 13.

[0032] The positioning base 11 includes a plurality of fixedly connected plate members 111; the guide mechanism 12 is arranged at the center position of the top end of the plate member 111;

[0033] The guide mechanism 12 includes a positioning plate 122 and an extension guide rail 121, and the extension guide rail 121 is welded to one side of the positioning plate 122. A limiting hole structure is provided on the positioning plate 122, and the positioning support plate 13 is movably connected to the guide mechanism 12 through the limiting hole structure; and the straight line where the center of the limiting hole structure is located coincides with the straight line where the center of the extension guide rail 121 is located;

[0034] A reinforcing steel plate 112 is provided between each of the plate components 111, and each of the plate components 111 and the inner wall of the reinforcing steel plate 112 forms a regular hexagonal structure, and the diameter of the circle where the center point of each side of the regular hexagonal structure is located is the same as the diameter of the circle where the outer wall of the steel casing is located; the positioning support plate 13 is movably connected to the guide mechanism 12, and the positioning support plate 13 is used to move along the extension guide rail 121 of the guide mechanism 12 to achieve position positioning between the steel cage and the steel casing.

[0035] The working process of this embodiment is as follows: the positioning frame is placed at the pile foundation hole, and the steel cage is slowly hoisted into the pile foundation hole by a crane. When hoisted to the preset depth, the transverse steel bars at the required positioning position on the steel cage are cut, and the steel cage is adjusted to a suitable position. When the steel cage is hoisted and fixed, the position of the steel cage relative to the steel casing needs to be adjusted. The positioning frame is used to control the position of the steel cage relative to the inner wall of the steel casing to be relatively uniform, that is, the positioning support plate is inserted into the cage hole of the steel cage through the guide mechanism, and the steel cage is fixed to facilitate the adjustment of the position of the steel cage. By controlling the position of the steel cage relative to the positioning support plate, the position of the steel cage relative to the inner wall of the steel casing can be quickly and stably controlled, thereby realizing the installation and positioning of the bridge pile foundation steel cage.

[0036] The utility model sets vertical through-hole plates at the four corners above the lifting plate through the lifting mechanism, connects the lifting ropes with the lifting rings, and connects the four lifting ropes to the lifting equipment on the crane at the same time, so that the center of gravity of the lifting mechanism is always consistent with the hook during the lifting process of the steel cage, thereby greatly improving the lifting stability of the steel cage. The hooks connected by the lifting ropes at the four corners of the lower side of the lifting plate are connected to the steel cage on all sides, and can adapt to steel cages of different lengths by adjusting the length of the lifting ropes. In addition, this lifting method ensures that the center of gravity of the crane hook, the lifting plate, and the steel cage always maintain a unified vertical line during the lifting process, and can avoid excessive concentration of the stress points of the steel cage, thereby reducing the possibility of deformation of the steel cage due to uneven stress during the lifting process and greatly improving the lifting stability. The positioning base of the utility model is specifically composed of I-beams welded together, and a reinforcing steel plate is welded at the bottom corner of the positioning base. The positioning frame is fixedly connected by welding to realize the integration of the positioning device, with low cost and no need for assembly, and high device stability. The extension and retraction direction of the positioning support plate is controlled by the guide mechanism provided on the positioning frame to ensure that the positioning support plate does not swing left and right; and after the positioning support plate is inserted into the steel cage hole, a preset triangular pad is placed between the steel cage hole and the positioning support plate to compensate for the sinking of the positioning support plate caused by the gravity of the steel cage, thereby fixing the steel cage in multiple directions, making the spacing between the steel cage and the inner wall of the steel casing relatively uniform. In this way, the installation stability of the steel cage during mechanical connection can be well guaranteed, and the positioning efficiency of the steel cage can be simply and effectively improved.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
