Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
Embodiment one
With reference to Fig. 1, a kind of elevator suspension rope tension is measured and regulating mechanism, comprises fag end screw rod 1, fag end seat 3, elastic element 5, jam nut 7, pressure sensor 9 and setting nut 11.
Above-mentioned fag end screw rod 1, fag end seat 3 and elastic element 5 is the existing structure of elevator, wherein the lower end of fag end screw rod 1 connects elevator suspension rope (not shown), fag end seat 3 screw collar is located on fag end screw rod 1, and elastic element 5 is stage clip, it to be set on fag end screw rod 1 and to be positioned at the top of fag end seat 3.Be provided with the upper and lower spring chair 13,15 be set on screw rod 1 at the two ends up and down of this elastic element 5, wherein lower spring pad 15 is arranged between elastic element 5 and fag end seat 3.
With further reference to Fig. 2 and Fig. 5, above-mentioned jam nut 7 is threaded on fag end screw rod 1, the adjusting sleeve 19 being arranged with regulating control 17 in the outside of jam nut 7 and being arranged between jam nut 7 and regulating control 17.Regulating control 17 is roughly the column of hollow, and it has hexagonal inner chamber 21.The sidewall of regulating control 17 offers a pair axially symmetrical adjustment window 23.Several adjustment circular hole 25 is provided with along its periphery on the top of regulating control 17.Corresponding to present pre-ferred embodiments, above-mentioned adjusting sleeve 19 is suitable with the shape of jam nut 7, and it is the cylindrical shape of hollow, and also has hexagonal inner chamber 22.On the periphery of adjusting sleeve 19, be provided with multiple adjusting hole 27.Adjusting sleeve 19 and jam nut 7 are for closely cooperating, so adjustment means (not shown), as latch, pin etc., can drive jam nut 7 to rotate to carry out tightening or relaxing through regulating window 23 and inserting adjusting hole 27 to rotate this adjusting sleeve 19.It should be noted that, when the shape specification of jam nut 7 becomes large, the present invention also removable adjusting sleeve 19 of laying down holds this jam nut 7 to have larger space, and such regulating control 17 is directly set on jam nut 7.When adjusting lock nut 7, if regulating control 17 coordinates with jam nut 7 not close, then adjustment means is carried out rotational lock nut 7 regulate through above-mentioned adjustment window 23; On the other hand, if regulating control 17 and jam nut 7 closely cooperate mutually, then adjustment means is inserted above-mentioned adjusting hole 27 rotary actuator 17 jam nut 7 can be driven to regulate.Visible, the use of adjustment means is convenient in the setting of regulating control 17 of the present invention, adjusting sleeve 19, time saving and energy saving, and without the need to manual regulation, is inconvenient to exert a force; And during this jam nut of manual regulation of the prior art, need to leave jam nut larger space for so that manual regulation, what add whole mechanism like that occupies space; And tonometry of the present invention and regulating mechanism can regulate the jam nut of different specification size, enhance its applicability.In addition, be also provided with arrangement for adjusting height 29 in the outside of regulating control 17, it is threaded mutually with the bottom of regulating control 17, and with jam nut 7 common support on above-mentioned upper spring pad 13.Like this, when the jam nut 7 of different size size is coupled on fag end screw rod 1, regulating control 17 can be carried out up-down adjustment by rotating this arrangement for adjusting height 29, being convenient to regulate jam nut 7 to regulate window 23 to be adjusted to suitable height and position.
Above-mentioned pressure sensor 9 is the pressure-variable resistance type sensor usually adopted in prior art, and it is provided with output indicator (not shown), and this pressure sensor 9 is prior art, therefore description is omitted at this.This pressure sensor 9 is provided with central through hole 31 to be set on fag end screw rod 1, and is supported on above-mentioned regulating control 17.
With further reference to Fig. 6 and Fig. 7, above-mentioned setting nut 11 has and regulates head 33 and self-regulation head 33 one to the guide part 35 of downward-extension.This adjustment head 33 has common hexagon shape, and its end face 36 has scale 37.The center of this setting nut 11 is provided with through tapped bore 38 its whole axis through from top to bottom, and is threaded on screw rod 1 by this through tapped bore 38.And guide part 35 is the cylindrical shape of hollow, it inserts in the central through hole 31 of pressure sensor 9, and between screw rod 1 and pressure sensor 9, regulates head 33 directly to contact with pressure sensor 9 simultaneously.Because there is coaxial line L between guide part 35, screw rod 1 and pressure sensor 9 three, like this by its directional tagging, be pressed on pressure sensor 9 with can making setting nut 11 pressure uniform, thus the tension data that pressure sensor 9 is exported is more accurate.
Tonometry of the present invention and control method roughly similar to prior art, when pressure survey, first by pine to tight rotating adjusting nut 11, until feel stressed, then jam nut 7 is unclamped by aforementioned means or method, such pressure sensor 9 starts to bear the pressure of elastic element 5 and outputs signal to outdevice, and now namely the pressure of elastic element 5 be equal to the tension force of suspension strop, thus complete the tonometric step of suspension strop.When carrying out tension adjustment, first setting nut 11 carried out rotating and drive screw rod 1 to move up and down, the so i.e. tensioning degree of adjustable suspension strop, until the pressure that pressure sensor 9 exports reaches the tension adjustment of specifying in the error limit of aviation value and namely completing suspension strop, and mentioned strain control process can indicate the anglec of rotation of setting nut 11 easily by the change of scale 37, be so also convenient to later stage employing similarity method and adjust.When not needing to carry out tonometry and regulating, micro-ly tighten jam nut 7.Repeat said process and can carry out tonometry and adjustment to remaining suspension strop.
Embodiment two
With further reference to Fig. 8 and Fig. 9, compared to embodiment one, the tonometry of the present embodiment and regulating mechanism are only that the regulating control 17 of regulating control 40 and the first embodiment is slightly different in shape, therefore only explain this regulating control 40 and omit the description of all the other parts.
Above-mentioned regulating control 40 is roughly the bar shape of hollow and axially cuts one section of arc-shaped edges along it, so just defines cylinder 42, irregular inner chamber 44 and single adjustment window 46.Equally, its top is provided with multiple adjustment hole 48 along its periphery.Like this, this regulating control 40 regulates window 46 also can reach adjustment to jam nut by offering one.And the regulating control 40 of the present embodiment without the need to trapping from the upper end of screw rod 1 is past when assembling, only need carry out installing from the side direction of screw rod, which not only simplifies the shape design of regulating control, and install more convenient.
It is pointed out that above-mentioned preferred embodiment is only and technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
