Embodiment Construction
[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a penstock triangle hoisting frame,
[0032] It includes a lifting lug 1, a fulcrum plate 2 fixedly connected with the lifting lug 1, centered on the center point a of the fulcrum plate 2, and divided into three parts 3 at equal angles, and a rotatable hanging beam is fixedly installed at the lower end of each part 3;
[0033] In the rotatable hanging beam, the upper end of the first hanging beam 4 is hinged to the slot 11 at the lower end of the fulcrum plate 2 through the first connecting shaft 5, and the lower end of the first hanging beam 4 is hinged to the upper end of the second hanging beam 7 through the second connecting shaft 6. The lower end of the suspension beam 7 is hinged to the steel plate clamp 9 through the third connecting shaft 8 .
[0034] The fulcrum plate 2 is a circular plate.
[0035] The lifting lug 1 is welded to the fulcrum plate 2 .
[0036] The lifting lug 1 i...

A pressure steel pipe triangular lifting rack comprises a lifting lug and a fulcrum plate fixedly connected with the lifting lug, the pressure steel pipe triangular lifting rack is divided into three parts in a uniform angle manner with the center point a of the fulcrum plate as a center, and the lower end of each of the three parts is fixedly provided with a rotatable lifting beam; and in rotatable lifting beams, the upper end of the first lifting beam is hinged to the fulcrum plate through a first connecting shaft, the lower end of the first lifting beam is hinged to the upper end of the second lifting beam through a second connecting shaft, and the lower end of the second lifting beam is hinged to a steel plate card through a third connecting shaft. The pressure steel pipe triangular lifting rack solves the problems of jittering and wobbling of a wire rope in the pressure steel pipe lifting process, caused by routine wire rope lifting, and has the advantages of small designed weight, flexible and convenient mounting and demounting, repeated use, safety and high efficiency.
Description
technical field [0001] The invention relates to a hoisting device for vertical hoisting and transportation hoisting of penstock steel pipes, in particular to a triangular hoisting frame for penstock steel pipes. Background technique [0002] At present, the vertical lifting and transportation of penstocks in hydropower stations generally use steel wire ropes to pass around the rope ends, snap rings, and steel plate clamps for hoisting and hoisting, and use steel wire ropes for hoisting operations. High-frequency hoisting during the use of steel wire ropes is very likely to cause damage to the steel wire rope, which is not good for cost savings. Moreover, after the steel wire rope is connected with the snap ring and the steel plate clamp, the height of the suspension rope is too long, and it is very likely that the vibration of the wire rope will cause damage to the wire rope and cause a safety accident; The situation of the hook may cause the situation that the construction ...
