[0029] Reference Figure 1As shown, when the outer mold trolley arrives at the designated construction position, the outer mold trolley rotates the hydraulic telescopic rod 2 to adjust the angle by rotating the bearing 1 to control the grounding position of the rotating base 6 at the bottom of the hydraulic telescopic rod 2, and at the same time moves the sliding component 4 on the sliding track to drive the position of the adjustable support rod 5 to reach the optimal supporting position. After reaching the supporting position, it is fixed to the sliding track 3 with screws to stably support the hydraulic telescopic rod 2, so that the entire auxiliary bracket can stably support the outer mold trolley; and the adjustable support rod 5 is evenly arranged along the telescopic direction of the hydraulic telescopic rod 2 under the connection of the sliding component 4, which can better support the hydraulic telescopic rod 2 and lift the auxiliary The overall stability of the bracket makes the overall skeleton structure of the outer mold trolley more stable during construction, and there will be no shaking that affects the quality of the project; when responding to different working environments, the angle of the rotating bearing 1 is rotated and the length of the hydraulic telescopic rod 2 is controlled to achieve the function of supporting the outer mold trolley. After determining the length and position of the hydraulic telescopic rod 2, the rotating base 6 at the bottom of the hydraulic telescopic rod 2 is rotated. The rotating base 6 is an I-shaped structure as a whole, and the position of the bottom tray can be adjusted so that the bottom of the hydraulic telescopic rod 2 can be completely in contact with the ground, thereby increasing the force contact range with the ground, and can better and firmly support the outer mold trolley skeleton and increase the stability of the outer mold trolley.

[0030] Reference Figure 4 、 Figure 5 、 Figure 6 As shown, the sliding track 3 provided on the hydraulic telescopic rod 2 is an I-type track structure, and the horizontal column 41 at the upper end of the sliding component 4 is slidably engaged with the sliding track 3, so that the sliding component 4 can slide on the sliding track 3 without falling off the sliding track 3. Applying lubricant between the sliding track 3 and the horizontal column 41 can reduce friction and reduce damage between components. After the sliding component 4 slides to the specified position, it can be tightened and fixed to the sliding track 3 with screws, so that the sliding component 4 can play a stable supporting role when cooperating with the adjustable support rod 5. The lower end of the sliding component 4 is provided with a rotating column 42, and the stud at the lower end of the rotating column 42 is engaged with the supporting inner of the adjustable support rod 5. The rod 51 is threadedly connected to realize the rotational connection between the sliding assembly 4 and the adjustable support rod 5. The stud connection can also be used to replace the adjustable support rod 5 in time when it is damaged, without affecting the construction progress and quality; the adjustable support rod 5 includes an inner support rod 51, an outer support rod 52, a telescopic block 53 and a plurality of through holes 54 evenly distributed along the height direction of the outer support rod 52. The telescopic block 53 on the inner support rod 51 can be snapped into cooperation with the through hole 54 on the outer support rod 52. By adjusting the height of the adjustable support rod 5, the requirements of the outer mold trolley for the support height of the trolley frame in different working environments can be met, so that the entire outer mold trolley bracket can stably support the outer mold trolley under different conditions.

[0031] Reference Figure 2 、 Figure 3As shown, a plurality of adjustable auxiliary brackets for the outer mold trolley are evenly arranged along the traveling direction of the trolley, which can increase the stable supporting effect of the auxiliary brackets on the outer mold trolley as a whole, and installing the auxiliary brackets at the weak points of the outer mold trolley steel frame can prevent the outer mold trolley from shaking during construction, thereby increasing the stability of the outer mold trolley during construction. The auxiliary brackets can also be retracted into the side steel frame of the outer mold trolley to facilitate the movement of the outer mold trolley.
