[detailed description of the invention]
Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Electric locomotive frequency conversion controller described in 1～2 by reference to the accompanying drawings, described controller comprises panel 1, base plate 2, handle 4, speed governing rotating disk 9, block 10, rotating shaft 11, angular transducer 12, micro-switch, connecting rod 17 and retracing spring 19; Described panel 1 is four corners corresponding being fixedly connected with respectively with base plate 2 by four fixed legs 3, panel 1 is equipped with concentric axis hole with the middle part of base plate 2, be arranged with the taper knob 5 for mounting handle 4 outward at the lateral surface axis hole of panel 1, be arranged with the copper sheathing 5 fixing by copper sheathing cushion block 6 outward at the medial surface axis hole of panel 1, this copper sheathing 5 does not contact base plate 2; Described base plate 2 medial surface axis holes are arranged with base pad piece 8 outward, be provided with speed governing rotating disk 9 at the medial surface of base plate cushion block 8, and the position of the corresponding base plate cushion block of the medial surface of base plate 28 both sides, bottom is respectively equipped with a block 10, utilize these two blocks 10 to reach speed governing rotating disk 9 is carried out spacing, avoid speed governing rotating disk 9 in the time rotating, to exceed the object of set angle; Described rotating shaft 11 axle bodies are connected with speed governing rotating disk 9, and one end of rotating shaft 11 is connected with handle 4 after running through successively the central shaft hole of speed governing rotating disk 9, base plate cushion block 8, base plate 2, copper sheathing 7 and taper knob 5, the other end of rotating shaft 11 is connected with the angular transducer 12 that is positioned at speed governing rotating disk 9 medial surfaces, thereby reaches the object that drives rotating shaft 11, speed governing rotating disk 9 and angular transducer 12 to rotate by turning handle 4;
Described micro-switch be divided into zero-bit micro-switch 13, advanced potential micro-switch 14 and after the micro-switch 15 of giving up the throne, these three micro-switchs are fixed on respectively the medial surface of base plate 2 by micro-switch cushion block 16, and the correspondence that has spacing is centered around the periphery of base plate cushion block 8, as required, zero-bit micro-switch 13 correspondences can be arranged on to the top of base plate cushion block 8, by advanced potential micro-switch 14 and after the micro-switch 15 corresponding both sides, middle part that are arranged on base plate cushion block 8 respectively of giving up the throne; Described angular transducer 12 is connected with corresponding frequency converter, and the angle of angular transducer 12 is made as 0～± 120 °, output voltage is 0～10V, and when angular transducer 12 rotates by 0 to+120 ° or 0 to-120 °, its output voltage is 0～10V; Simultaneously, when angular transducer 12 is during in zero degree, the contact of zero-bit micro-switch 13 contacts with speed governing rotating disk 9, be handle 4 while being failure to actuate, speed governing rotating disk 9 contacts all the time with the contact of zero-bit micro-switch 13, now, zero-bit micro-switch 13 is in closure state, the angle of angular transducer 12 is 0, and output voltage is 0, thereby can electric locomotive be remained static by controlling frequency converter; When drive rotating shaft 11 and speed governing rotating disk 9 to rotate by turning handle 4, speed governing rotating disk 9 can trigger corresponding advanced potential micro-switch 14 or after the micro-switch 15 of giving up the throne, thereby reaching by Frequency Converter Control electric locomotive, the break-make of utilizing these two micro-switchs advances and the object retreating, meanwhile, the size that can also utilize angular transducer 12 to change time institute's output voltage in angle reaches by the object of Frequency Converter Control electric locomotive running velocity;
For the velocity of rotation that ensures speed governing rotating disk 9 can be too not fast, can be in one end of the medial surface of a base plate 2 hinged connecting rod 17 in base angle place, the shaft correspondence of this connecting rod is between block and speed governing rotating disk, and the center shaft 18 of connecting rod 17 to the inside direction is outstanding, and corresponding and 9 moving contacts of speed governing rotating disk, connecting rod 17 other ends that while is positioned at another base angle place of base plate 2 medial surfaces in correspondence arrange retracing spring 19, in the time rotating speed governing rotating disk 9 by handle 4, the application force of retracing spring 19 can make speed governing rotating disk 9 all the time in strained condition, this actv. has ensured that the velocity of rotation of speed governing rotating disk 9 can be too not fast, and then also actv. has avoided electric locomotive to occur the phenomenon of tachypragia.
While implementing electric locomotive frequency conversion controller described in the utility model, only need control rotating shaft 11 by one-handed performance handle 4, speed governing rotating disk 9 and angular transducer 12 rotate and just can complete the control to electric locomotive, for example: when angular transducer 12 is during along with the angular turn of speed governing rotating disk 9 at 0 to+120 °, the voltage of angular transducer 12 meeting corresponding output 0～10V along with the change of angle, thereby complete the operation that the speed of electric locomotive is increased gradually by frequency converter, now, because speed governing rotating disk 9 can contact with advanced potential micro-switch 14 in leaving zero-bit micro-switch 13, therefore, electric locomotive can forward action in along with the variation of angular transducer 12 output voltages corresponding change speed, in the time that angular transducer 12 rotates in the angle of 0 to-120 ° along with speed governing rotating disk 9, angular transducer 12 can be exported the voltage of 0～10V equally, but due to speed governing rotating disk 9 now in the time leaving zero-bit micro-switch 13, be with after the micro-switch 15 of giving up the throne contact, therefore, electric locomotive can change accordingly speed along with the variation of angular transducer 12 output voltages in moving backward.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
