Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 show schematically show the terminating set of a kind of elevator hoisting steel band according to the first mode of execution of the present invention.
As shown in Figure 1, this device comprises socket 1, voussoir 2, plug-in unit 3 and rotating shaft 4.
Voussoir 2 and plug-in unit 3 are built in socket 1 at least partly.Plug-in unit 3 is connected with socket 1 by rotating shaft 4.Voussoir 2 is between first gripping surface 301 and the second gripping surface 101 of socket 1 of plug-in unit 3.Traction steel band 5 is around voussoir 2 and be clamped between the first gripping surface 301 and the second gripping surface 101.
For the positive pressure making traction steel band be subject to is little, extend the working life of traction steel band.The locking angle of voussoir is 15 ° ~ 30 °.Needing to select according to actual design, in the present embodiment, is 20 °.
Rotating shaft 4 runs through through hole 302 on plug-in unit 3 and is connected in series by socket 1, and rotating shaft 4 is fixed in socket 1, and plug-in unit 3 can 4 rotate around the shaft, can change the size of the angle β of the first gripping surface 301 and the second gripping surface 101.
The axis of rotating shaft 4 is positioned on the center line face of the first gripping surface 301 length direction.When making plug-in unit 3 carry out rotation adjustment thus, there will not be and rock.
For strengthening the clamping force to traction steel band 5, can by carrying out sandblasting, polishing, annular knurl or be provided with groove increasing surface roughness with the contact surface 201 of traction steel band 5 at the first gripping surface 301, second gripping surface 101 and voussoir 2.As shown in Figure 2, in the present embodiment, be realize by offering groove 303 on the first gripping surface 301.Correspondingly, the contact surface 201 of the second gripping surface 101 and voussoir 2 offers groove too.
As shown in Figure 1,3, socket 1 comprises the header board 102, rear plate 103 and the side plate 104 that are fixedly connected with, and by welding, riveted joint, hinged mode is fixed together, and also can be one-body molded.Be preferably the latter, the relative-position error of three can be improved thus, ensure that the dimensional accuracy of socket 1, also can make full use of production material simultaneously, save manufacture cost.
When the terminating set of a kind of elevator hoisting steel band of the present invention is assembled, first plug-in unit 3 is passed in rotating shaft 4, more together load in socket 1, rotating shaft 4 is fixed in socket 1.Then traction steel band 5 is wound around voussoir 2 through after the through hole under socket 1, and is together placed in socket 1.Due to the latching characteristics that voussoir 2 has, traction steel band 5 is clamped in socket 1.
After traction steel band 5 is subject to load F effect, plug-in unit 34 rotates, until the angle β of the second gripping surface 101 and the first gripping surface 301 equals the key groove α of voussoir 2 under force around the shaft.Adjusted by the rotation of plug-in unit 3, what make the second gripping surface 101 and the first gripping surface 301 and traction steel band 5 contacts when being always plane-plane contact, the pressure uniform distribution that traction steel band 5 is subject to.Decrease the wearing and tearing of traction steel band 5, extend working life.
Fig. 4 is the structural representation of the plug-in unit 3 in the second mode of execution of the present invention.
The difference of the present embodiment and the second embodiment is: rotating shaft 4 is fixed on plug-in unit 3; The locking angle of voussoir 2 is 25 °.
Rotating shaft 4 can be fixed on plug-in unit 3 by modes such as welding, rivet, be hinged, also can be one-body molded with plug-in unit 3, be preferably the latter, not only can make full use of manufactured materials thus, save manufacturing cost, and be convenient to install.
Plug-in unit 3 has two mounting holes, the engaging of the two ends of rotating shaft 4 is articulated with in two mounting holes, rotating shaft 4 and plug-in unit 3 can together around the shaft the axis of 4 rotate.
When the terminating set of a kind of elevator hoisting steel band of the present invention is assembled, first load in socket 1 by plug-in unit 3, the two ends engaging of rotating shaft 4 is articulated with in two mounting holes on socket 1.Then traction steel band 5 is wound around voussoir 2 through after the through hole under socket 1, and is together placed in socket 1.Due to the latching characteristics that voussoir 2 has, traction steel band 5 is clamped in socket 1.
After traction steel band 5 is subject to load F effect, plug-in unit 3 drive under force rotating shaft 4 around the shaft 4 axis rotate, until the angle β of the second gripping surface 101 and the first gripping surface 301 equals the key groove α of voussoir 2.Adjusted by the rotation of plug-in unit 3, what make the second gripping surface 101 and the first gripping surface 301 and traction steel band 5 contacts when being always plane-plane contact, the pressure uniform distribution that traction steel band 5 is subject to.Decrease the wearing and tearing of traction steel band 5, extend working life.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
