[0042] Embodiment:

[0043] The embodiment provides a support equipment for bridge construction, which is used to solve the technical problem that the support equipment for bridge construction in the prior art is inconvenient to adjust the support position size. The support equipment for bridge construction comprises a base 1, a rotating rod 2, a support rod 3, a first mounting block 4, a second mounting block 5, a first support plate 7 and a second support plate 8, wherein:

[0044] The base 1 has a mounting cavity 11, and the base 1 is a hollow cuboid.

[0045] The rotating rod 2 is rotationally installed in the mounting cavity 11, the axis direction of the rotating rod 2 is arranged along a first direction, and the rotating rod 2 is arranged horizontally.

[0046] The distance between the support rod 3 and the rotating rod 2 gradually increases from one end of the support rod 3 to the other end, that is, an included angle a is formed between the axis of the support rod 3 and the axis of the rotating rod 2, and the range of the included angle a is 20°≤a≤60°. For example, the included angle a can be 20°, 30°, 40°, 50°, 60°, etc. If the included angle is too small, the area of the first support plate 7 and the second support plate 8 will be too small, which is not conducive to support. If the included angle is too large, the adjustable range will be too small, and material will be wasted. In addition, the projection of the support rod 3 in the second direction coincides with the projection of the rotating rod 2 in the second direction, that is, the axis of the support rod 3 and the axis of the rotating rod 2 are located in the same horizontal plane, and the first direction and the second direction are perpendicular to each other.

[0047] A threaded hole is formed in one end of the first mounting block 4, and an outer thread is formed on the outer side wall of the rotating rod 2, which is matched with the inner thread in the threaded hole. The first mounting block 4 is screwed on the rotating rod 2.

[0048] The second mounting block 5 is slidably mounted on the support rod 3 along the axis direction of the support rod 3. Optionally, a circular hole is formed in one side of the second mounting block 5, which is matched with the support rod 3. The support rod 3 is slidably inserted into the second mounting block 5 through the circular hole.

[0049] The connecting rod 6 is slidably mounted on the first mounting block 4 and the second mounting block 5 along the second direction. The axis of the connecting rod 6 is arranged along the second direction, and the axis of the connecting rod 6 and the axis of the support rod 3 are located in different horizontal planes. In this way, through the arrangement of the connecting rod 6, the rotating rod 2 is prevented from driving the first mounting block 4 to rotate synchronously when the rotating rod 2 rotates, so that the first mounting block 4 moves linearly along the first direction. At the same time, when the first mounting block 4 moves linearly along the first direction, the second mounting block 5 moves linearly on the support rod 3, and the distance between the first mounting block 4 and the second mounting block 5 changes.

[0050] The first support plate 7 is slidably mounted on the top end of the base 1 and connected with the first mounting block 4. The first support plate 7 can move along the third direction, that is, the first support plate 7 can move up and down. The first direction, the second direction and the third direction are perpendicular to each other. In this way, through the arrangement of the first support plate 7 connected with the first mounting block 4, when the first mounting block 4 moves linearly along the first direction, the first support plate 7 moves linearly along the first direction on the base 1 synchronously.

[0051] The second support plate 8 is slidably mounted on the top end of the base 1 and connected with the second mounting block 5. The second support plate 8 can move along the third direction, that is, the second support plate 8 can move up and down. In this way, through the arrangement of the first support plate 7 connected with the second mounting block 5, when the second mounting block 5 moves linearly on the support rod 3, the second support plate 8 moves linearly on the base 1 synchronously.

[0052] With the above structure, when the bridge construction support equipment is used, the bridge construction support equipment is first moved to the position to be supported, and then the distance between the first support plate 7 and the second support plate 8 is adjusted according to the size of the part to be supported. When the distance between the first support plate 7 and the second support plate 8 needs to be adjusted, the rotating rod 2 is driven to rotate, and the connecting rod 6 is provided so that the first mounting block 4 screwed on the rotating rod 2 moves back and forth in the first direction, and at the same time, the second mounting block 5 moves back and forth on the support rod 3 along the axis direction of the support rod 3. The distance between the support rod 3 and the rotating rod 2 gradually increases from one end of the support rod 3 to the other end, thereby achieving the purpose of adjusting the distance between the first mounting block 4 and the second mounting block 5. The first support plate 7 is connected with the first mounting block 4, and the second support plate 8 is connected with the second mounting block 5, thereby achieving the purpose of adjusting the distance between the first support plate 7 and the second support plate 8. After the distance between the first support plate 7 and the second support plate 8 is adjusted, the first support plate 7 and the second support plate 8 are driven to move in the third direction until the first support plate 7 and the second support plate 8 are supported at the part to be supported, and then the driving is stopped. Therefore, by cooperation of the rotating rod 2, the support rod 3, the first mounting block 4, the second mounting block 5 and the connecting rod 6, the distance between the first support plate 7 and the second support plate 8 can be adjusted only by rotating the rotating rod 2, so that the bridge construction support equipment provided by the utility model is more convenient to adjust the size of the support position.
