Front end；Being provided with thrust support in described adjustable shelf rearward tracks, thrust support is provided with for finely tuning adjustable shelf front and back position
Adjusting part.
Track described in this utility model is that channel-section steel that is opposing by two and that be arranged in parallel is constituted, plane machining in orbit
The bolt hole I having many group pitch-rows to be a；Each two bar shaped bolts hole that described adjustable shelf is processed respectively by lower plane both sides with
And connector I combines with track, each bar shaped bolt hole two stomidium heart is away from for a, and two ends, described adjustable shelf bottom surface are respectively provided with
There are buckle I and buckle II；Each one group of hole heart that described thrust support is processed respectively by lower plane both sides is away from the bolt hole for a
II and connector II combine with track.Described assembly pulley is 2 multiplying power assembly pulleys, uses monolithic pulley structure.
The screwed hole for spinning adjusting part it is machined with, at riser on the riser of thrust support described in this utility model
Middle lower portion has is easy to the square opening that variable-amplitude steel wire rope passes through.
This utility model achieves the continuous tensioning function of trailer wagon variable-amplitude steel wire rope, and has the advantages that
A, luffing tensioner are arranged in counter-jib, not only just can complete tight rope work in counter-jib, it is not necessary to climb to a higher point
Operation, adds the safety of tight rope operation, alleviates the weight of amplitude variation trolley especially, improves tower crane lifting performance.
B, assembly pulley use monolithic pulley, are 2 multiplying power assembly pulleys, and this not only greatly reduces tensile force, the most favorably
In whole tensioning device structure part stress.
After C, tight rope, chain block can be liberated, separately use it for anything else, improve its utilization rate.
D, creatively employing thrust support and bolt and nut component thereof, the most whole tensioning device structure is subject to
Power, achieves the continuous tensioning of variable-amplitude steel wire rope especially.
E, have that simple structure, flexible operation be convenient, hommization, safe and reliable, the advantage such as practical.
