Detailed description of the invention
Describe in detail with reference to the accompanying drawings according to chain erector of the present utility model.
Referring to figs. 1 through Fig. 4, comprise according to chain erector of the present utility model: the first plate 1; Hydraulic jack 2, one end abuts the first plate 1; Pressing plate 3, abuts the other end of hydraulic jack 2; Dividing plate 4, abuts pressing plate 3; Second plate 5, bolt is connected to the first plate 1 (bolt connects employing bolt 7 and nut 8), completes pre-assembled chain 6 and is connected between dividing plate 4 and the second plate 5; Wherein, the fundamental chain that hydraulic jack 2 provides pressure to make pre-assembled chain 6 saves the circular hole 621 of the bearing pin 611 correspondence press-in outer plate 62 of 61.Here, first the structure of chain is described, as shown in Figure 4, chain 6 comprises fundamental chain joint 61, outer plate 62, inner link 63.Outer plate 62 and fundamental chain save 61 and fix, and are called outer link.Outer link pulls down the rear remaining part of outer plate 62 of side, is called fundamental chain joint 61.It should be noted that, complete pre-assembled chain 6 and refer to each bearing pin 611 correspondence of the fundamental chain of the chain 6 of disconnection joint 61 is penetrated in each circular hole 631 of inner link 63, and each bearing pin 611 each circular hole 621 corresponding with on outer plate 62 of fundamental chain joint 61 aligns.And the first plate 1 plays the effect of the reaction force of support hydraulic pressure jack 2 and opposing chain 6.Because the cooperation of bearing pin 611 and outer plate 62 is interference fit, the pressure that hydraulic jack 2 provides needs to reach 30000N.
According in chain erector of the present utility model, with bolts between the first plate 1 and the second plate 5, different hydraulic jack 2 can be adapted to by adjusting bolt 7 and nut 8, to utilize existing hydraulic jack, thus greatly save cost.Chain erector structure of the present utility model is simple, volume is little, in addition, with boltsly makes easy accessibility, can pull down and deposit, save space after using.
According in an embodiment of chain erector of the present utility model, with reference to Fig. 2, the first plate 1 and the second plate 5 correspondence can be provided with multiple through hole H respectively, wear multiple bolt 7 for correspondence.First plate 1 and the second plate 5 are fixed by multiple nuts 8 of multiple bolt 7 and correspondence by the first plate 1 and the second plate 5.Bolt 7 adopts high-strength bolt, and nut 8 adopts high-strength nut.
According in an embodiment of chain erector of the present utility model, with reference to Fig. 2, the first plate 1 and the second plate 5 respectively correspondence are provided with four through hole H, wear four bolts 7 for correspondence.
According in an embodiment of chain erector of the present utility model, with reference to Fig. 2, four through holes are uniformly distributed in the first plate 1 and the second plate 5 respectively.
According in an embodiment of chain erector of the present utility model, the yield strength of single bolt 7 is 800800N/mm2, and the diameter of single bolt 7 is 10mm.In whole device, because the screw rod of bolt 7 is the most concentrated stressed places, the intensity of screw rod needs to reach instructions for use.When the yield strength of bolt is 800800N/mm2, when diameter is 10mm, the pulling force that single bolt 7 can provide is F=800N/mm2X3.14X10/2X10/2=62800N, if adopt 4 bolts 7, the pulling force that then four bolts 7 can provide is Fn=62800X4=251200N, safety coefficient is 5, then Fn/5=251200/5=50240>30000N can meet instructions for use.
According in an embodiment of chain erector of the present utility model, the diameter of the through hole on the first plate 1 and the second plate 5 is 12mm.
According in an embodiment of chain erector of the present utility model, with reference to Fig. 3, each circular hole 621 on the corresponding outer plate of dividing plate 4 62 is provided with perforation 41.Perforation is for ensureing that bearing pin 611 can not contact with pressing plate 3 after passing outer plate 62.In one embodiment, the diameter of perforation is 100mm.
According in an embodiment of chain erector of the present utility model, perforation coaxial line corresponding on the circular hole 621 that each bearing pin 611 of fundamental chain joint 61 is corresponding with on outer plate 62, dividing plate 4.
