Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings and specific embodiments, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Example 1
The utility model provides a fixed trailing arm of steel construction bridge equipment with flexible, includes horizontal support 3 and vertical support 5, and the main part is triangle-shaped. The triangle main body is composed of two isosceles right-angle triangular supports 41 and 42 which are parallel to each other and are adjacently arranged, and the two adjacent right-angle sides are rotatably connected and fixed through a limiting piece 16; the limiting part 16 is composed of a limiting rod penetrating through two adjacent right-angle edges and limiting nuts sleeved on two sides of the limiting rod, and the surface of the limiting rod is smooth.
Two right-angle sides separated from the triangular support are respectively and fixedly connected with the horizontal support 3 and the vertical support 5, and a support rod 8 is arranged between the horizontal support 3 and the vertical support 5; the support rod 8 is rotatably connected with the horizontal support 3 and detachably and fixedly connected with the vertical support 5.
When the supporting arm is in a supporting working state, referring to fig. 1, the horizontal support 3 is connected with an upper chord plate 1 through a bearing beam 2, and the upper chord plate 1 is assembled on a steel structure bridge through a bolt 14. Two adjacent right-angle sides are fixedly connected in a locking mode through a bolt connecting pair 6 and form a stable triangular supporting structure together with a supporting rod 8.
During disassembly, the end of the support rod connected with the vertical support is disassembled, so that the support rod 8 is in a movable state, the bolt connection pair 6 is disassembled, so that the two triangular supports 41 and 42 connected through the limiting part 16 in a rotating manner can rotate, finally, the vertical support 5 is rotated to a position parallel to the horizontal support 3, and meanwhile, the support rod also rotates towards the other side, which is shown in fig. 2.
