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

[0024] like Figure 1 、 2 As shown, a supporting device for bridge construction in the field of bridge engineering comprises: a base plate 1 arranged on the construction ground; a lifting mechanism 2 arranged on the base plate 1; a support plate 3 arranged on the top of the lifting mechanism 2, a ladder 31 fixedly connected to the side wall of the support plate 3, and a protective net 32 ​​provided on the side wall of the support plate 3; a bridge bottom support mechanism 4 arranged in the middle of the support plate 3; and bridge side support mechanisms 5 arranged on both sides of the support plate 3, the bridge side support mechanisms 5 being rotatably connected to the bridge bottom support mechanism 4.

[0025] Lifting mechanism 2 comprises a lifting rod 21 and a sliding track 22. Lifting rod 21 is located in the middle of base plate 1. The upper portion of lifting rod 21 is telescopic. The telescopic end of telescopic rod 51 drives support plate 3 up and down to accommodate bridges of varying heights and provide support to the bridge bottom. Sliding track 22 is located on either side of lifting rod 21. The sidewalls of sliding track 22 are fixedly connected to the fixed end of lifting rod 21. The bottom of sliding track 22 is also fixedly connected to base plate 1. The sidewalls of sliding track 22 are provided with a "convex"-shaped depression, which runs vertically along the sliding track 22.

[0026] A limit rod 33 is provided at the bottom of the support plate 3, and a slider is provided at the bottom of the limit rod 33. The slider is also in a "convex shape". The slider moves vertically in the sliding track 22. The sliding track 22 limits the left and right movement of the limit rod 33, further limiting the shaking of the support plate 3. When the lifting rod 21 is in the shortest form, the slider is located at the bottom of the sliding track 22. As the lifting rod 21 rises, the slider moves on the sliding track 22. The top of the sliding track 22 is a closed structure to prevent the telescopic rod 51 from being lifted too high, causing the limit rod 33 to disengage from the sliding track 22.

[0027] The ladder 31 is fixed to the side of the support plate 3. The length of the ladder 31 is the same as that of the lifting rod 21 in its lowest position. When the telescopic end is in the lowest position, the bottom of the ladder 31 contacts the base plate 1, allowing operators to easily climb up the ladder 31 to inspect the support plate 3 and other upper parts. When the device is in operation, the telescopic rod 51 rises, and the bottom of the ladder 31 rises accordingly, preventing unauthorized personnel from arbitrarily climbing the ladder 31 to a high position and causing safety accidents. When professionals need to perform maintenance, after taking safety precautions, they hang a connecting ladder or set up a fork ladder at the bottom of the ladder 31 to bridge the distance between the bottom of the ladder 31 and the base plate 1. At the same time, workers can also reach the bottom of the ladder 31 to perform work on the bottom of the bridge.

[0028] A storage roll 321 is provided on the top of the protective net 32, and the storage roll 321 wraps the protective net 32. The protective net 32 ​​rotates and falls from the storage roll 321. A counterweight block 322 is provided at the bottom of the protective net 32. The counterweight block 322 is placed on the upper surface of the base plate 1 under the action of gravity. When the lifting rod 21 rises, the counterweight block 322 pulls the protective net 32 ​​in the storage roll 321 out. The protective net 32 ​​blocks some external interference and reduces the dispersion of dust, thereby ensuring the smooth progress of bridge construction.

[0029] The bridge bottom support mechanism 4 includes a spring damper 41, a first reinforcement plate 42 and a hinge 43. The spring damper 41 is arranged in the middle of the support plate 3. The hinge 43 connects the bottom of the first reinforcement plate 42 and the top of the spring damper 41. When the lifting rod 21 rises, the first reinforcement plate 42 supports the bottom of the bridge under the thrust of the support plate 3. When the bridge has an inclination angle, the first reinforcement plate 42 will rotate with the inclination angle of the bridge under the rotation of the hinge 43 to ensure that the first reinforcement plate 42 supports the bottom of the bridge. When the bridge is under construction, when large loads such as unloading occur on the bridge, the spring damper 41 will buffer and reduce damage to the bridge.

[0030] When this device is supported on the side of the bridge, the side of the bridge can be supported by the bridge side support mechanism 5. The bridge side support mechanism 5 includes a telescopic rod 51, a universal ball 52, a second reinforcement plate 53 and a connecting rod 54. The telescopic rod 51 is arranged on both sides of the support plate 3. A universal ball 52 is provided on the top of the telescopic rod 51. The universal ball 52 is rolled and connected to the bottom of the second reinforcement plate 53. The connecting rod 54 connects the first reinforcement plate 42 and the second reinforcement plate 53.

[0031] The connecting rod 54 is L-shaped, one end of the connecting rod 54 is fixed to the bottom of the first reinforcement plate 42, and the other end of the connecting rod 54 is rotatably connected to the second reinforcement plate 53. The height of the second reinforcement plate 53 is lower than the height of the first reinforcement plate 42. When the first reinforcement plate 42 tilts, the connecting rod 54 drives the second reinforcement plate 42 to tilt together, and the universal ball 52 can make the second reinforcement plate 53 rotate in multiple directions.

[0032] When the first reinforcing plate 42 completes supporting the bottom of the bridge, the telescopic rod 51 is activated to tilt the second reinforcing plate 53 upward to further support the side wall of the bridge. The second reinforcing plate 53 cooperates with the first reinforcing plate 42 to make the support of the bridge more stable.

[0033] When the bottom of the bridge is too wide, multiple devices are used to cover the bottom and both sides of the bridge.

[0034] The first reinforcement plate 42 and the second reinforcement plate 53 are both provided with water holes 6 on their surfaces. When it rains or the upper part of the bridge is watered for maintenance, water entering the gap between the reinforcement plate and the bridge can be quickly discharged, reducing the slight sliding caused by water.

[0035] The bottom plate 1 is detachably connected to a threaded anchor rod 11 , which penetrates the bottom plate 1 and enters the construction ground. The threaded anchor rod 11 increases the stability of the bottom plate 1 and makes the support more stable.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
