[0017] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 6 It can be seen that a highway bridge construction support device includes a bottom plate 1, a guard plate 2 is rotatably provided at the end of the bottom plate 1, a lower support 3 is provided on the bottom plate 1, and an upper support 4 is provided on the guard plate 2. The upper support 4 is connected with the lower support 3 to form a vertical fixation between the guard plate 2 and the bottom plate 1;

[0019] When the guard plate 2 is perpendicular to the base plate 1 , the side surface of the guard plate 2 contacts the end of the base plate 1 , and the end of the base plate 1 supports the bottom of the guard plate 2 .

[0020] When the utility model is used in a specific way,

[0021] Rotate the guard plate 2 so that it is perpendicular to the base plate 1. At this time, the bottom side of the guard plate 2 contacts the end of the base plate 1, and a supporting surface is formed on the outside of the guard plate 2. The force acting on the guard plate 2 is applied to the end of the base plate 1, which is more stable. Connect the ends of the upper support 4 and the lower support 3 to form an oblique support, so that the angle between the guard plate 2 and the base plate 1 is fixed to complete the support.

[0022] A fixing device is arranged on the side of the bottom plate. The fixing device is a well-known technology in the art and will not be described in detail here. It can fix the bottom plate so that it cannot move during support.

[0023] Connecting ears 5 are provided on both sides of the end of the bottom plate 1, and an L-shaped groove 6 is opened on the connecting ear 5. Connecting rods 7 sliding in the groove 6 are extended from both ends of the guard plate 2, and the connecting ears 5 extend outward from the end of the bottom plate 1. There are two forms between the guard plate 2 and the bottom plate 1. One is the storage state in which the guard plate 2 is in close contact with the bottom plate 1 for easy storage and placement, and the other is the vertical state in the supporting state, in which the connecting rod 7 slides in the groove 6. The connecting rod 7 in both states is located at the end of the groove 6 and is fixed by rotating the limit plate 15 arranged on the outside of the connecting ear 5. The limit plate 15 is provided with a notch cooperating with the connecting rod 7. After rotation, it can be stuck on the connecting rod 7, so that the position of the connecting rod 7 is fixed, thereby maintaining the verticality between the guard plate 2 and the bottom plate 1. When the guard plate 2 is stored in close contact with the bottom plate 1, due to the L-shaped structure of the groove 6, the ends can be aligned for easy storage.

[0024] The bottom plate 1 is symmetrically provided with placement grooves 8, and oblong holes 9 are provided on both sides of the placement grooves 8. The end of the lower support 3 slides in the oblong hole 9, and a first wedge block 10 is sleeved on the bottom of the lower support 3. A second wedge block 11 cooperating with the first wedge block 10 is slidably provided in the bottom plate 1, and a wire drawing screw 12 is provided in the bottom plate 1. The wire drawing screw 12 is threadedly connected to the second wedge block 11. Rotating the wire drawing screw 12 makes the two second wedge blocks 11 move in opposite directions. A fixing sleeve 13 is threadedly connected to the outer side of the upper end of the lower support 3. The guard plate 2 is symmetrically provided with clearance grooves 14. The end of the upper support 4 is rotatably set in the clearance groove 14, and the upper support 4 has the same diameter as the lower support 3.

[0025] During support, first rotate the tension screw 12 to make the second wedge block 11 retract inward, and the first wedge block 10 can be away from the guard plate 2. At this time, align the ends of the lower support 3 and the upper support 4, and then rotate the fixing sleeve 13 to make the fixing sleeve 13 cover the upper support 4. At this time, the lower support 3 and the upper support 4 are on the same axis, and then rotate the tension screw 12 to make the second wedge block 11 extend outward, pushing the first wedge block 10 close to the guard plate 2, pushing the lower support 3 to move, so that the lower support 3 and the upper support 4 are close to each other, forming support for the upper end of the guard plate 2.

[0026] During the support process, the bottom of the guard plate 2 is subjected to force on the end of the base plate 1, and the connecting rod 7 is not subjected to force and will not break even after long-term use, thereby extending the service life of the equipment; the upper end of the guard plate 2 is supported by the upper support 4 and the lower support 3. Compared with the adjustable screw in the prior art, the bottom is adjusted in position by a wedge block, and the force is more stable and not easy to be damaged, so it can be used stably for a long time.

[0027] Compared with the prior art, the utility model has the following beneficial effects: modifying the stress position of the guard plate, avoiding stress on the shaft and the thread, protecting the equipment from premature damage, and extending the service life of the equipment.
