Problems solved by technology

[0002] China's infrastructure industry is developing rapidly. In the construction of roads and bridges, China is at the leading level in the world; the construction of traditional bridges across rivers or bridges across valleys takes a long time. In large-scale military exercises or wars, the traditional way of building bridges It is not suitable for the characteristics of fast marching, poor maneuverability, and low passing efficiency; and in the existing military, most of the temporary construction of steel truss bridges using Bailey sheets is used to quickly pass through rivers or valleys, but it is simply composed of Bailey sheets Due to its own structural reasons, the steel truss bridge is only suitable for small-span river canals or valleys, and has a good supporting effect. Once the span is large, it cannot provide good support and has poor stability. The steel truss bridge has a small bearing capacity and cannot pass heavy vehicles, which limits the passage of heavy vehicles on the march to a certain extent

Embodiment 1

[0045] Such as Figure 1-5 As shown, a cable-stayed rigid truss special equipment system; including a steel truss 2, a first vehicle 1; the first vehicle 1 is loaded with a support rod 4, and the support rod 4 is a telescopic rod, and the support rod 4 The top is provided with a fixing piece 14, one side of the fixing piece 14 is connected with a plurality of tie rods 5, and the other ends of the plurality of tie rods 5 are all connected with the steel truss 2, and the plurality of tie rods 5 are uniformly arranged along the steel truss 2 Horizontally distributed, the rigid truss is erected on both sides of the river or ditch; the other side of the top fixing part 14 of the support rod 4 is connected to a plurality of tie rods 5, and the other ends of the plurality of tie rods 5 are connected to the second vehicle 3, the second vehicle 3 is a counterweight vehicle; ropes 6 are connected between the plurality of pull rods 5, and buffer members 8 are arranged on the ropes 6.

Embodiment 2

[0052] Such as Figure 6-7 As shown, the support rod 4 is a "gate" structure, and the support rod 4 of the "gate" structure has two support rods 4, which form two sets of cable-stayed structures, and pull the steel truss 2 at the same time on both sides of the steel truss 2 , to increase the stability; the support rod 4 is a "human" structure, and the support rod 4 is set in a "human" structure, and is fixed at the center of the steel truss 2 through the tie rod 5.

Embodiment 3

[0054] On the basis of Embodiment 1, in order to make the tie rod 5 play a better tension effect, increase the interaction between the steel truss 2 and the tie rod 5, so that the steel truss 2 can play a better supporting role, increase the load capacity, increase Stability, the distance between two adjacent tie rods 5 on the steel truss 2 is D, the angle formed by the tie rods 5 and the support rod 4 is θ, the range of θ is 45-90°, the height of the support rod 4 is H, two adjacent The length of the tie rod 5 close to the support rod 4 is L1, and the length of the tie rod 5 away from the support rod 4 is L2, then D satisfies the following relationship:

[0055] D=φ sinθ(L2-L1)H;

[0056] Among them, the unit of D, H, L1 and L2 is m; φ is an adjustment constant, and the value range is 0.8-2.36.

[0057] Dn-D n-1 =β·1 / 2n; In the above formula: Dn-D n-1 is the distance between the nth tie rod 5 and the n-1th tie rod 5 on the steel truss 2, in m; β is the relationship coeffic...
