[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, the mobile trolley for cast-in-place construction of the culvert cover in this embodiment includes a single-row frame, a connecting beam 1, a top distribution beam 2, a template, a moving wheel 3 and a support block 4.

[0025] In this embodiment, three groups of single-row frames are arranged in parallel and at equal intervals, and the single-row frames are in a gate-shaped frame structure. Specifically, the single-row frame includes three vertical beams 6 and one horizontal beam 5, and the horizontal beam 5 is fixed to the top of the vertical beam 6, and the two ends of the horizontal beam 5 protrude from the edge of the vertical beam 6. An oblique reinforcement beam 15 and a horizontal reinforcement beam 16 are also connected between adjacent horizontal beams 5. The horizontal beam 5 and the vertical beam 6 are both made of I-beams, and the oblique reinforcement beam 15 and the horizontal reinforcement beam 16 are both made of channel steel, and the horizontal beam 5, the vertical beam 6, the oblique reinforcement beam 15 and the horizontal reinforcement beam 16 are welded into a whole.

[0026] The connecting beam 1 is arranged between the single-row frames and is detachably connected to the three single-row frames. Specifically, the connecting beam 1 is arranged horizontally and connected to the vertical beam 6. The positions where the vertical beam 6 and the connecting beam 1 are connected are fixed with connecting plates 7. The connecting plates 7 are arranged vertically and are wider than the widths of the vertical beam 6 and the connecting beam 1. The connecting plates 7 are welded to the vertical beam 6 or the connecting beam 1 to improve stability. A fixing hole is provided on the part not covered by the connecting plate 7, and a first connecting bolt 8 is provided in the fixing hole, so that the vertical beam 6 and the connecting beam 1 are connected through the connecting plate 7 and the first connecting bolt 8, which is convenient for installation and disassembly. More specifically, the connecting beam 1 is a channel steel, and the connecting plate 7 is a steel plate. The four corners of the connecting plate 7 are provided with fixing holes and the first connecting bolts 8 are installed, so that the structure is safe and reliable under the premise of easy installation and disassembly.

[0027] In this embodiment, a plurality of top distribution beams 2 are arranged at equal intervals on the top of the single-row frame, and the two ends of the top distribution beam 2 are flush with the two cross beams 5 at the edge. The top distribution beam 2 spans the single-row frame and is detachably connected to the single-row frame. Specifically, the top distribution beam 2 is a channel steel, and a second connecting bolt 9 is arranged between the top distribution beam 2 and the cross beam 5 at the top of the single-row frame. The top distribution beam 2 is connected to the cross beam 5 at the top of the single-row frame through the second connecting bolt 9, so as to facilitate the disassembly and assembly between the top distribution beam 2 and the single-row frame. In addition, because the top distribution beam 2 is arranged above the cross beam 5, the structure can be guaranteed to be safe and reliable.

[0028] In this embodiment, the template is set on the top distribution beam 2, and the edges of the template are all located outside the top distribution beam 2 and the cross beam 5. The template includes a plurality of strip plates 10 spliced ​​in sequence. The length direction of the strip plates 10 is consistent with the top distribution beam 2, and each strip plate 10 is connected to a plurality of top distribution beams 2 at its bottom. Specifically, the strip plates 10 are made of steel plates, and adjacent strip plates 10 are connected by welding, and the strip plates 10 and the top distribution beam 2 are connected by spot welding. When disassembling, the top distribution beam 2 can be disassembled from the single-row frame to complete the disassembly of the template, or the template can be cut into strip plates 10 for disassembly.

[0029] In this embodiment, the mobile trolley for cast-in-place construction of the culvert cover further includes a side support assembly, which is arranged on the outer side surface of the single-row frame or the side surface of the outermost connecting beam 1 close to the culvert side wall 14, and the side support assembly is retractable. Specifically, the side support assembly includes a horizontally arranged sleeve 11, an adjusting nut 12 rotatably arranged at one end of the sleeve 11, a screw 13 threadedly connected to the adjusting nut 12 and partially inserted into the sleeve 11, and an abutment component arranged at one end of the screw 13 away from the sleeve 11, and the end of the sleeve 11 away from the adjusting nut 12 is connected to the outer side surface of the single-row frame or the side surface of the outermost connecting beam 1 close to the culvert side wall 14, and the abutment component abuts against the culvert side wall 14. The abutment component is composed of a U-shaped plate 17 fixedly connected to the screw 13 and a sleeper 18 clamped in the U-shaped plate 17. The thickness of the sleeper 18 is greater than the depth of the inner side of the U-shaped plate 17, so that only the sleeper 18 abuts against the culvert side wall 14, effectively preventing damage to the culvert wall.

[0030] In this embodiment, the moving wheel 3 is arranged at the bottom of the side of the vertical beam 6, and the support block 4 is arranged directly below the vertical beam 6. Specifically, the support block 4 adopts a steel wedge to play the role of bearing weight and adjusting height.

[0031] The working principle of the mobile trolley for cast-in-place construction of the culvert cover in this embodiment is:

[0032] The single-row frames are connected by connecting beams 1 to form an integral frame. Since the connecting beams 1 and the single-row frames are detachably connected by connecting plates 7 and first connecting bolts 8, compared with welding in the prior art, it is effectively convenient to disassemble and assemble the connecting beams 1 and the single-row frames. A top distribution beam 2 for installing the template is installed on the top of the single-row frame. Since the top distribution beam 2 and the single-row frame are detachably connected by bolts, compared with welding in the prior art, it is effectively convenient to disassemble and assemble the top distribution beam 2 and the single-row frame, and also convenient to disassemble and assemble the template and the single-row frame, so as to facilitate transportation and turnover between multiple cover culverts.

[0033] In this embodiment, the bottom of the mobile trolley for cast-in-place construction of the culvert cover is equipped with moving wheels 3, and the footsteps use steel wedges to adjust the height and the overall elevation of the trolley. The mobile trolley moves to the right position, the steel wedges are placed, the trolley is fixed, and then the steel bars are tied. Finally, the top plate concrete is poured symmetrically. When the top plate reaches the designed strength, it is supported by the steel wedges, the steel wedges are removed, and the walking pulleys fall to the ground to form a gap between the mobile trolley and the poured concrete, so that the mobile trolley can move to the next section.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
