The specific embodiment
Fig. 1 ~ 2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 2 pair of the utility model of accompanying drawing.
As shown in Figure 1, the elevator fuselage saves upwards by standard knot one, and abutting joint forms, there are four column tubes at four angles of each standard knot, the corresponding docking assembling with the column tube of following standard knot of the column tube of top standard knot, form at last from ground to the standard knot column tube track of four long distances at fuselage top, elevator car is installed in up and down operation under the traction of steel rope on this standard knot column tube track, roller 3 described in the utility model also moves at the track that this standard knot column tube forms, and the friction of dependence and standard knot column tube rotates.
This traction-type construction lifting machine car supply unit mechanics is comprised of alternating current generator 1, raising speed machine 2, roller 3, high-speed transfer belt 4, base 5, turning rolls 6, torque spring 8 and low speed transmissions belt 9.Turning rolls 6 is installed in the rightmost side of base 5.Turning rolls 6 rotating shafts place are equipped with torque spring 8, and torque spring 8 can produce a larger thrust, so that produce enough large friction force between roller 3 and the standard knot column tube 7 roller 3 are rotated.Turning rolls 6 tops are " Contraband " shape structure of upward opening, and roller 3 is installed in " Contraband " shape structure upper oral part, and roller 3 middle parts are that inside circular-arc with vertical standard knot column tube 7 contacts are connected.One end of roller 3 is output shaft, raising speed machine 2 is fixed on the middle part of base 5, the low speed rotor of raising speed machine 2 is connected by the output shaft of low speed transmissions belt 9 with roller 3, raising speed machine 2 is realized rotor by the conversion of low speed to high speed by internal gear engagement, and the rotating speed of the high speed rotating shaft of raising speed machine 2 is 10 times of low speed rotating shaft rotating speed in this device.The high speed rotor of raising speed machine 2 is connected by the rotor of high-speed transfer belt 4 with alternating current generator 1, thus 1 generating of band motor alternator.
As shown in Figure 2, circuit part can be divided into four parts: rectifier 10, pressure regulator 11, storage battery 12 and inverter 13 in the electrical generator.
Rectifier 10 in the electrical generator has formed a three-phase full wave rectifier circuit by 6 rectifier diode D1-D6, and 6 rectifier diodes have formed two node G, H.Alternator frame winding 15 draw three wires be connected in the three phase bridge rectifier, by the valve action of diode, the AC rectification that alternating current generator 1 is sent becomes direct current (DC).Alternating current generator 1 has been drawn three terminal A, C, D, and terminal A is connected with node G, and terminal D links to each other with node H, and terminal C links to each other with node G by alternating current generator excitation winding 16.
The terminal A of alternating current generator 1 has connected and has linked to each other with pressure regulator terminal B after the starting switch 14.The terminal C of alternating current generator 1 links to each other with pressure regulator terminal F.The terminal D of alternating current generator 1 links to each other with pressure regulator terminal E.Terminal A, the D of alternating current generator 1 links to each other with the positive and negative electrode of storage battery 12 again simultaneously.Pressure regulator 11 is regulated the voltage of alternating current generator 1 output, makes it remain on stationary value, charges to storage battery 12 when storage battery 12 lower voltage simultaneously.Be connected to the positive and negative electrode of inverter 13 during the positive and negative electrodes in same of storage battery 12.The 12V dc inverter that inverter 13 is exported storage battery 12 is to power to the load behind the 220V alternating current.
The specific works process is as follows: starting switch 14 and the interlock of wireless pager starting switch.After starting switch 14 closures, the wireless pager in the car starts simultaneously, and this actuation signal is sent to the frequency converter of control towing machine.Towing machine begins to rotate, and drags car movement by steel rope simultaneously, and roller 3 is owing to and exist larger friction force to begin rolling between the standard knot column tube 7.Because roller 3 links to each other with the low speed rotor of raising speed machine 2 by belt, and the high speed rotor of raising speed machine 2 links to each other by the rotor of belt with alternating current generator 1, so roller 3 is with the rotor setting in motion of motor alternator 1.During starting switch 14 firm closure, the rotor of alternating current generator 1 not yet rotates, alternating current generator 1 Non voltage output.This moment, the voltage of storage battery 12 was added on the R2 and two divider resistances of R3 of pressure regulator 11, voltage between resistance R 2, the R3 is too low at this moment, can't make stabilivolt ZD1 reverse breakdown, this moment, aerotron VT2 was in off condition, aerotron VT1 is in conducting state, and generator excitation winding 16 consists of C/LOOP by aerotron VT1 and storage battery 12, and storage battery 12 provides exciting current to alternating current generator 1, alternating current generator 1 is in the separate excitation generating state, and load this moment provides power supply by storage battery 12.
Rising along with alternating current generator 1 rotating speed, the output voltage of alternating current generator 1 also can raise, when the output voltage of alternating current generator 1 during greater than the voltage of storage battery 12, alternating current generator 1 begins the self-excitation generating, rectifier both end voltage by alternating current generator 1 provides exciting current for excitation winding 16, and beginning is to storage battery 12 chargings.Be elevated to when the output voltage of alternating current generator 1 on the setting value of pressure regulator 11 in limited time, this voltage is added on divider resistance R2 and the R3, voltage between two divider resistance R2 and the R3 just can make stabilivolt ZD1 reverse breakdown and reverse-conducting, aerotron VT2 conducting this moment, aerotron VT1 cut-off, the energized circuit of the generator excitation winding 16 of alternating current generator 1 just is cut off, and this moment, the magnetic flux of alternating current generator 1 descended, and output voltage will descend.Drop to when the output voltage of alternating current generator 1 under the setting value of pressure regulator 11 in limited time, voltage between two divider resistance R2 and the R3 with regard to deficiency so that stabilivolt ZD1 reverse breakdown and reverse-conducting, aerotron VT2 cut-off this moment, aerotron VT1 conducting, the energized circuit of the generator excitation winding 16 of alternating current generator 1 just recloses, this moment, the magnetic flux of alternating current generator 1 rose, output voltage will rise, and this process constantly circulates so that alternating current generator 1 stable output voltage under the effect of pressure regulator 11.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
