Detailed description of the invention
Flexible bolster first embodiment as shown in Figure 1, Figure 2 shown in Fig. 5 and Fig. 6, comprise the beam body be made up of left section of beam 1 and right section of beam 2, the two ends of beam body are provided with lifting appliance.Left section of beam 1 and right section of beam 2 are hollow structure, and both axis in a straight line.Wherein, the internal diameter of left section of beam 1 is equal with the external diameter of right section of beam 2 or roughly equal, and so right section beam 2 can be nested in left section of beam 1, and the outer wall of the inwall of left section of beam 1 and right section of beam 2 is fitted, and both form complete beam body.Regulate it to insert the degree of depth of left section of beam 1 by right section of beam 2 and the out movement of left section of beam 1, beam body on the whole just defines stretching structure, and then the length of beam body is also adjustable.
As shown in Figure 1, Figure 2 with shown in Fig. 6, left section of beam 1 and right section of beam 2 are equipped with some isometrical jacks 8 along its length, and the jack 8 on different beam can cooperatively interact, and is connected and fixed by the latch 9 as positioning element, after being connected and fixed, left section of beam 1 and right section of beam 2 relative positioning.During lifting, the span that user is different according to goods selects different jacks 8 to insert latch 9, so just the length of beam body can be fixed up.
Flexible bolster first embodiment as shown in Fig. 3 to Fig. 9, except comprising the left section beam 1 substantially identical with the first embodiment and right section of beam 2, also comprise and accept nested beam 3, left section of beam 1 is nested in the through hole accepting nested beam 3 two ends respectively with right section of beam 2.The through hole accepting nested beam 3 two ends all has certain length, left section of beam 1 all can be slided to right section of beam 2 in corresponding through hole, therefore, left section of beam 1 is also out movement with right section of beam 2, and pass through out movement, beam body on the whole just defines stretching structure, and then the length of beam body is also adjustable.
As shown in Fig. 3, Fig. 4, Fig. 7 and Fig. 8, the two ends of accepting nested beam 3 are provided with the knock hole 12 isometrical with jack 8, latch 9 as positioning element can insert in knock hole 12 and jack 8 simultaneously, so, left section of beam 1 and right section of beam 2 are being located relative to accepting to be undertaken being connected by latch 9, jack 8 and knock hole 12 after nested beam 3 slides, the length of beam body to be fixed up.
Preferably, accept nested beam 3 and formed by the steel-pipe welding of two sections of different tube diameters, every section of steel pipe is equipped with knock hole 12.Wherein, left section of beam 1 is nested in the larger steel pipe of caliber, and right section of beam 2 is nested in the larger steel pipe of caliber.As shown in Figure 8 and Figure 9, two sections of steel pipes adopt after nested arrangements to be welded and fixed again, and both junctions are also provided with strengthens gusset 10, and the bottom of accepting nested beam 3 is also connected to two bearings 1111.
The flexible bolster provided in second embodiment, accepts nested beam 3 because have, so more can meet the lifting requirement of large span goods.In addition, the internal diameter of left section of beam 1 is same with the external diameter of right section of beam 2 equal or roughly equal, and when so lifting by crane little span goods, the nested beam 3 of undertaking also can be dismantled by user, directly uses lifting cargo after left section of beam 1 and right section of beam 2 nested encryptions, its occupation mode is versatile and flexible, lifts by crane applied widely.
In above-mentioned two embodiments, lifting appliance is connected to the end of left section of beam 1 and right section of beam 2, and be described with the lifting appliance of left section of Liang1Chu below, the lifting appliance of right section of Liang2Chu has identical structure with the lifting appliance of left section of beam 1.
As shown in Figure 5 and Figure 6, lifting appliance comprises tie-beam body and the horizontal swing pipe 4 of vertical beam body, and for abutting lifting rope, the two ends of horizontal swing pipe 4 are provided with Anti-rope drop plate 5.During lifting, all lifting ropes all hang over two of horizontal swing pipe 4, and namely wherein a lifting rope one end is hung on hoisting crane, and the other end hangs over two of horizontal swing pipe 4; Another lifting rope one end falling lifting cargo tangles goods, and the other end is also hung on two of horizontal swing pipe 4.
Preferably, horizontal swing pipe 4 is pipe or oval tube, and lifting rope can not scrape rope after hanging.
Preferably, the middle part of horizontal swing pipe 4 is provided with two pieces of lifting rope positioning plates 6, and the tail end of lifting rope positioning plate 6 is provided with limit bolt 7 upper end and is provided with limit bolt 7, two pieces of lifting rope positioning plates 6, forms the position-limited trough that is held lifting rope between limit bolt 7 and left section of beam 1.Pass through said structure, lifting cargo can have another kind of lifting method: during lifting, lifting rope one end is hung on hoisting crane, the arc surface that the other end is overlapped on horizontal swing pipe 4 through position-limited trough lie on lifting cargo, the arc surface of lifting rope and horizontal swing pipe 4 is moving contact, can prevent from scraping rope, horizontal swing pipe 4 is also hung with safety rope, the safety rope other end is hung on loop wheel machine hook place, this safety rope does not bear cargo weight, only for hanging flexible bolster, this kind of lifting method can reduce sling height greatly.
The flexible bolster of above-described embodiment, also have make simple, convenient from heavy and light, assembling, lifting, disassembling section, adapt to multiple lifting span, save the lifting time, reduce the plurality of advantages such as sling height.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
