The working principle of the utility model is as follows:
when in installation, firstly, the nose tower 1 and the tail tower 2 are built at two ends of a span, and the heights of the nose tower 1 and the tail tower 2 are designed according to the height difference of the two ends of the span, so that the levelness of the suspension rope 9 is ensured to meet the use requirement.
After the machine head tower 1 and the machine tail tower 2 are built, one ends of two suspension ropes 9 are fixed with the hanging point 7, the other ends of the two suspension ropes 9 extend forwards to bypass the corresponding head redirecting wheels 3 and then extend backwards to bypass from the upper parts of the front side supporting guide wheels 4, then extend backwards to bypass from the upper ends of the rear side supporting guide wheels 5, finally extend downwards from the upper ends of the tensioning wheels 6, and a counterweight tightening box 8 is fixedly arranged at the tail ends of the suspension ropes 9, so that the suspension ropes 9 are tensioned through the counterweight tightening box 8.
Grooves are formed in the outer cylindrical surfaces of the head redirecting wheel 3 and the tensioning wheel 6, and the suspension ropes 9 are located in the grooves, so that the suspension ropes 9 are prevented from jumping and sliding under wind load, and the suspension ropes 9 cannot slide and move left and right in a tensioning state.
When the suspension wire 9 is tensioned, the head redirection pulley 3 rotates along the head rotation shaft 13, thereby reducing friction with the suspension wire 9.
The tension of the suspension rope 9 is adjusted by increasing and decreasing the balancing weight, so that the two ends of the suspension rope 9 keep a horizontal range, and the two bearing mechanisms 10 between the adjacent two bearing mechanisms are kept relatively parallel.
The bearing mechanism 10 is fixedly connected with the suspension cable 9 through the clamping assembly 16, and the bolts 20 are screwed so that the upper clamping block 18 and the lower clamping block 19 clamp the suspension cable 9. Finally, the upper carrier roller set and the lower carrier roller set are respectively connected inside the machine head tower 1, the machine tail tower 2 and the bearing mechanism 10 through hooks.
Because of the large span, the swing is easy to be influenced by transverse wind load. To strengthen the transverse rigidity, the lateral supports 11 are used to connect two sides of the bearing mechanism 10 into a whole, so as to strengthen the transverse rigidity of wind load condition and keep stable.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
