Specific implementation mode
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
Embodiment one
Referring to Fig.1, a kind of elevator suspension rope tension measures and regulating mechanism, including screw rod 1, fag end seat 3, elastic element 5,
Locking nut 7, pressure sensor 9 and adjusting nut 11.
Above-mentioned screw rod 1, fag end seat 3 and elastic element 5 are the existing structure of elevator, wherein the lower end connection electricity of screw rod 1
Terraced suspension strop (not shown), 3 screw thread of fag end seat are set on screw rod 1, and elastic element 5 is compression spring, is set on screw rod 1 simultaneously
Positioned at the top of fag end seat 3.It is equipped with the upper and lower spring pad 13,15 being set on screw rod 1 in the upper and lower ends of the elastic element 5,
Spring pad 15 is wherein descended to be arranged between elastic element 5 and fag end seat 3.
With further reference to Fig. 2 and Fig. 5, above-mentioned locking nut 7 is threaded on screw rod 1, in the outer sheath of locking nut 7
Equipped with adjuster 17 and the adjusting sleeve being arranged between locking nut 7 and adjuster 17 19.The generally hollow column of adjuster 17
Shape, the inner cavity 21 with hexagon.Axially symmetric a pair of of adjusting window 23 is offered on the side wall of adjuster 17.It is adjusting
The top of device 17 is equipped with several adjusting circular holes 25 along its periphery.Corresponding to present pre-ferred embodiments, above-mentioned adjusting sleeve 19 with
The shape of locking nut 7 is adapted, and is hollow cylindrical shape, and the also inner cavity 22 with hexagon.In adjusting sleeve 19
On periphery, it is equipped with multiple adjusting holes 27.Adjusting sleeve 19 is tight fit with locking nut 7, so tool (not shown) is adjusted,
Such as bolt, pin etc., across adjusting window 23 and being inserted into adjusting hole 27 can drive locking nut 7 to rotate to rotate the adjusting sleeve 19
To be tightened or be relaxed.It should be noted that when the shape specification of locking nut 7 becomes larger, the present invention is also removable to lay down tune
To accommodate the locking nut 7 with larger space, such adjuster 17 is directly set on locking nut 7 the whole series 19.It is adjusting
When locking nut 7, if adjuster 17 and 7 not close cooperation of locking nut, adjust tool across above-mentioned adjusting window 23 to rotate
Locking nut 7 is adjusted；On the other hand, if adjuster 17 is mutually fitted close with locking nut 7, the tool that adjusts is inserted into
Stating 27 rotary regulator 17 of adjusting hole can drive locking nut 7 to be adjusted.As it can be seen that the adjuster 17 of the present invention, adjusting sleeve
The use of adjusting tool is convenient in 19 setting, time saving and energy saving, without adjusting manually, it has not been convenient to exert a force；And in the prior art
The locking nut of adjusting manually when, need to leave for locking nut larger space in order to adjust manually, increase like that entire
Mechanism occupies space；Moreover, the tonometry and regulating mechanism of the present invention can to the locking nut of different specification size into
Row is adjusted, and enhances its applicability.In addition, height adjustment device 29 is additionally provided in the outside of adjuster 17, with adjuster 17
Bottom end be mutually threadedly coupled, and be supported on jointly on above-mentioned upper spring pad 13 with locking nut 7.In this way, working as different size size
Locking nut 7 when being coupled on screw rod 1, adjuster 17 can be subjected to upper downward by rotating height adjustment device 29
Section adjusts its adjusting window 23 to suitable height and position and convenient for locking nut 7 is adjusted.
Above-mentioned pressure sensor 9 is the pressure-variable resistance type sensor of generally use in the prior art, is equipped with output and refers to
Show device (not shown), which is the prior art, therefore description is omitted herein.During the pressure sensor 9 is equipped with
Heart through-hole 31 is supported on being set on screw rod 1 on above-mentioned adjuster 17.
With further reference to Fig. 6 and Fig. 7, above-mentioned adjusting nut 11, which has, adjusts head 33 and 33 one of self-regulation head downwards
The guide part 35 of extension.There is common hexagon shape, top surface 36 to have scale 37 on the adjusting head 33.The adjusting nut 11
Center be equipped with perforation threaded hole and penetrate through that its is entire axial from top to bottom, and screw rod is threaded in by the perforation threaded hole
On 1.And guide part 35 be hollow cylindrical shape, be inserted into pressure sensor 9 central through hole 31 in, and positioned at screw rod 1 with
Between pressure sensor 9, while adjusting head 33 and directly being contacted with pressure sensor 9.Because of guide part 35, screw rod 1 and pressure
Between 9 three of sensor there is coaxial line L 11 pressure of adjusting nut can be made equably to press in this way by its guiding role
Tightly on pressure sensor 9, so that the tension data that pressure sensor 9 exports is more accurate.
The tonometry and adjusting method and the prior art of the present invention is substantially similar, in pressure measurement, first by pine to tightly
Then rotating adjusting nut 11 unclamps locking nut 7, such pressure sensing until feeling stress by aforementioned device or method
Device 9 starts to bear the pressure of elastic element 5 and outputs signal to output equipment, and the pressure of elastic element 5 is equal to outstanding at this time
The tension of lanyard, so as to complete the step of to suspension strop tonometry.When carrying out tension adjustment, first by adjusting nut 11 into
Row rotates and screw rod 1 is driven to move up and down, and can be adjusted the tensioning degree of suspension strop in this way, until pressure sensor 9 is defeated
The pressure gone out reaches the interior tension adjustment completed to suspension strop of error range of specified average value, and mentioned strain is adjusted
Process easily can indicate the rotation angle of adjusting nut 11 by the variation of scale 37, also allow for the later stage in this way using phase
It is adjusted like method.It is micro- to tighten locking nut 7 when that need not carry out tonometry and adjust.Repeat above-mentioned mistake
Journey can carry out tonometry and adjusting to remaining suspension strop.
Embodiment two
With further reference to Fig. 8 and Fig. 9, compared to embodiment one, the tonometry and regulating mechanism of the present embodiment are only that
Adjuster 40 and the adjuster 17 of first embodiment are slightly different in shape, thus only the adjuster 40 is explained and
Omit the description of remaining parts.
The generally hollow bar shape of above-mentioned adjuster 40 simultaneously cuts one section of arc-shaped edges axially along, just forms in this way
Cylinder 42, irregular inner cavity 44 and single adjusting window 46.Equally, top is equipped with multiple adjustment holes 48 along its periphery.In this way,
The adjuster 40 also may achieve adjusting to locking nut by opening up an adjusting window 46.Moreover, the adjuster of the present embodiment
40 in assembly without from the upper end of screw rod 1 toward trapping, need to only be installed from the side of screw rod to by adjuster 40, in this way
The shape design of adjuster is not only simplified, and is installed more convenient.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements according to this, and the protection of the present invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
