Fig. 4 demonstrates and passes the further ins and outs of schematically vertically scheming also illustration rope stretching 8 and rope attachment 14 that rope 8 is got.Rope attachment 14 have: at least one first connection element 14a, and it is fixed to or can be fixed to the first end 8a of rope; With at least one second connection element 14b, it is fixed to or can be fixed to the second end 8b of rope.Each connection element 14a, 14b have the corresponding end 8a that supplies rope 8, rope engaging zones 14a1, the 14b1 that 8b inserts.Corresponding rope engaging zones 14a1,14b1 are pressed with attached end 8a or 8b respectively.Said two connection element 14a, 14b shaped design become to make them to insert each other.In this case, connection element 14b is formed into the form of shell capsule and comprises that the tubular with deformed area 14b2 admits regional 14b3.Connection element 14a shaped design becomes to be similar to bolt.Connection element 14a has head 14a2, and the overall diameter of head 14a2 is slightly less than the interior diameter of the admittance zone 14b3 of corresponding shell cryptomere connection element 14b, makes these two connection element 14a, 14b easily to insert each other.Head 14a2 combines with the cylindrical section that extends longitudinally and pass step or protuberance, and said cylindrical section also forms rope engaging zones 14a1 less than head 14a2 on diameter.Alternately, this regional 14a1 can for example also have some annular ridge or other part that is fit to that is used to lock form joint (form-locking joint) on its periphery.Connection element 14b has the restrictions 16 to connection element 14a head 14a2.
In this example, for ease of being installed on the main housing portion 4a, rope 8 and rope attachment 14 or its individual components by prefabricated be single installation unit, this installation unit has predetermined installation length L
MIn this example, installation length L
MBy given as follows:
L
M＝L
A-Dx
In this case, L
ABe the length in the periphery of the rope 8 zone main housing portion 4a that will be arranged in, Dx is used for the length with the suitable amplitude of rope 8 reversible elasticity ground tensioning in the step afterwards.In this example, for form said installation unit should with the rope 8 cut to the long Ls of actual rope be slightly less than installation length L
M, this is to have predetermined length because of connection element 14a, 14b self.
Fig. 5 a demonstrates the schematically vertical figure that passes that rope 8 shown in Fig. 4, that be in uninstalled first state or installation unit get, and wherein restricts 8 loosely around unshowned main housing portion 4a.Fig. 5 b demonstrates and passes schematically vertical figure that rope 8 shown in Fig. 4, that be in second state is got; Under this state; Rope 8 has installed and the end 8a of its rope, 8b are bonded together by rope attachment 14 securely, wherein restrict 8 with preparatory tensioning state around main housing portion 4a.
When rope 8 be in first state (see Fig. 5 a) and connection element 14a, when 14b inserts each other, the head 14a2 of connection element 14a is positioned at the preset distance Dx place before the restrictions 16.Like this for rope 8 or said installation unit define first predetermined around length, first predetermined around length at this corresponding to installation length L
MAnd be slightly less than the length L of main housing portion 4a periphery as previously mentioned
ANow, come aforementioned second state in order to make rope 8 or installation unit, tensioned lines 8 arrives restrictions 16 places (seeing Fig. 5 b) up to head 14a2.In this case, admit regional 14b3 to be used as the guide portion of head 14a2 similarly.Through being applied to these two connection element 14a, the last relative simple tools of 14b, can carry out said tensioning.Under second state, (see Fig. 5 b), so that rope 8 or reversible elasticity installation unit extend to is second predetermined around length, second predetermined be slightly larger than around length first predetermined around length and correspond essentially to the length L of main housing portion 4a periphery
AIn this way, the rope 8 that is in installment state with preparatory tensioning state around main housing portion 4a.Obviously, through predetermined rope parameter, cylinder parameter and predetermined installation length L
M, the acting in conjunction of rope attachment 14 or its connection element 14a, 14b and restrictions 16 limits second length and the preparatory tensioning degree around circle of rope 8.In this example, rope attachment 14 are also as rope tension element and safety element.
In order to implement the preparatory tensioning of aforementioned rope 8, also can use under second state length basically less than main housing portion 4a periphery length L
ARope 8 or installation unit.But, thus this will mean that rope 8 is local powerful by being pressed on the cylinder 2.This should be avoided to a great extent, because it is very thin usually to be used to process the sheet of cylinder 2.
Another kind of possibility is based on the compound shape of first and second modification; This is a kind of scheme of reality in practice because not only restrict 8 and also cylinder 2 all always show certain elasticity or surrender.Under second state shown in Fig. 5 b, the deformed area 14b2 plastic deformation of right-hand connection element 14b and by on the periphery that is pressed in rope engaging zones 14a1, make among the deformed area 14b2 material radially with axially around head 14a2.Therefore, rope attachment 14 have formed a kind of compression fittings, and wherein, said two connection element 14a, 14b have under impaction state along the shape of the form that locks longitudinally of rope 8.Therefore, guaranteed the joint of rope with reliable fashion, even thereby said rope in the fast rotational process of cylinder 2, can not break away from yet.
Fig. 6 demonstrates the schematically vertical figure that passes that rope 8 rope attachment 18 are got.These rope attachment 18 are similar to the rope attachment 14 shown in Fig. 4,5a and the 5b.But, different with the latter is that these rope attachment 18 have at similar with the connection element 14a of modification shown in Fig. 4,5a and the 5b in shape two connection element 18a, 18b.In addition, structure shown in Fig. 6 has independently shell capsule 18c in the centre, and at the inserting opening that each side has can supply the first and second connection element 18a, 18b to insert, each connection element 18a, 18b are connected to end 8a, the 8b of rope.Middle shell capsule 18c has interior partition wall 18c1, and the side surface of interior partition wall 18c1 is as being directed against said two connection element 18a, the head 18a2 of 18b, the restrictions 16 of 18b2.Therefore, middle shell capsule 18c is as the independently restrictions to rope attachment 18, and at least the first connection element second connection element 18a, 18b then is assigned to this restrictions.Connection element 18a, 18b insertion and the joint and 8 the tensioning of restricting of end portion thus in middle case capsule 18c is through carrying out with mode identical under the situation of modification shown in Fig. 4,5a and the 5b.In other words, each head 18a2 is in the same place with the 18b2 tractive, the rope engaging zones 18a1, the 18b1 that shell capsule zone 18c2 are pressed on connection element 18a, 18b are last, thereby shell capsule zone 18c2 radially and axially centers on head 18a2,18b2.Middle shell capsule 18c also is used as tensioning and the safety element of rope and connection element 18a, 18b.
