[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a movable energy-saving support frame for large-load cast-in-place box culverts, including multiple support columns 1, multiple brackets 2 welded between the multiple support columns 1, support plates 3 welded to the inner walls of two brackets 2, and electric push rods 4 fixedly installed on the upper surface of the support plates 3 by bolts A. The lengths of the support columns 1 and brackets 2 can be adjusted according to the height of the box culvert to meet construction needs. The support distance can be extended by cooperating with two or three of these devices. The output end of the electric push rod 4 is fixedly connected to a connecting plate 5, and one side of the connecting plate 5 is fixedly connected to a frame plate 6 by bolts B. A frame plate 7 is welded to the upper surface of one of the brackets 2.

[0024] This equipment uses four supporting columns 1 and three sets of brackets 2 to form a frame structure. The formwork for pouring is supported by the extendable A-frame plates 6 on both sides and the B-frame plate 7 on top, which greatly reduces the manpower required for the repeated disassembly and assembly of traditional support frames, thereby improving work efficiency.

[0025] The surface of the support column 1 is provided with a threaded hole, and a C bolt for fixing the diagonal brace 8 is inserted through the threaded hole. A base plate 9 is welded to the bottom end of the diagonal brace 8, and a support rod 10 is welded to the upper surface of the base plate 9. The top end of the support rod 10 is welded to one of the brackets 2. A connecting frame 11 is rotatably connected to the bottom end of the support column 1, and a wheel 12 is provided on the lower surface of the connecting frame 11.

[0026] By setting the base plate 9, the equipment can be supported after the position is determined, which improves the stability during support and avoids damage to the wheels 12 caused by the weight of the formwork and concrete, thus improving the load-bearing effect.

[0027] A frame base 13 is welded to the bottom of the support column 1. A rotating seat 14 is rotatably connected inside the frame base 13. Bearings are fixedly installed on both sides of the connecting frame 11. A sleeve 15 is rotatably connected to the connecting frame 11 through the bearings. A hydraulic cylinder 16 is fixedly installed inside the sleeve 15. The output end of the hydraulic cylinder 16 is fixedly connected to the surface of the rotating seat 14.

[0028] Once the equipment is positioned, the hydraulic cylinder 16 can be activated to push the connecting frame 11 outward to rotate, thereby making the wheels 12 higher than the base plate 9. This allows the base plate 9 to contact the ground, supporting the entire equipment and the upper template, reducing equipment damage, and improving the overall load-bearing capacity.

[0029] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
