The drive motor mentioned in the present program is a frequency-control motor, the electrical-control mechanism comprises a controller and two or four frequency converters controlling the drive motor respectively, outputs of the controller correspondingly control the frequency converters used for the drive motors on the right side as well as control the frequency converters on the left side, the output of the four distance sensors is the input of the controller. The controller adopts micro-controller circuit and the frequency converters adopt widely-known technology.
Description
Affiliated technical field:
The utility model relates to a kind of device that the track weight-lifting equipment is advanced of controlling, especially a kind of device of rail travelling crane preventing gnawing rail.
Background technology:
In the prior art, known the most approaching technology is, authorize disclosed No. 02135563.0 patent by the applicant's application and by State Intellectual Property Office, this patent disclosure a kind of technical scheme of rail-gnawing prevention device for double-track vehicle, this scheme can prevent to gnaw the rail phenomenon between driving wheel and the track effectively.But, because the drive motor of this scheme is the conventional motor that adopts, thus the electrical control mechanism of controlling and driving motor with regard to more complicated, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and provide a kind of device technique scheme of rail travelling crane preventing gnawing rail, the drive motor of this scheme is to adopt frequency control motor, controller only need be controlled the frequency converter to each drive motor power supply like this, just can adjust the speed of motor by the variation of line frequency, reach the purpose that driving wheel is not gnawed rail.
This programme is realized by following technical measures: the driving wheel that includes parallel two-orbit and track upper support driving body, two of driving that driving wheel rotates or four drive motor and retarder are arranged on the driving wheel, in driving just, oppositely the driving wheel of working direction is nearby square, near two tracks rang sensor is housed, in addition, also has electrical control mechanism, the characteristics of this programme are that described drive motor is a frequency control motor, there are a controller and two or four frequency converters of controlling each drive motor respectively in described electrical control mechanism, the right side drive motors frequency converter is controlled in the output of described controller respectively, with control left side drive motor frequency converter, the output of described four rang sensors is inputs of controller.The concrete characteristics of this programme also have, and described controller is the controller that adopts single chip machine controlling circuit.Described frequency converter is the frequency converter that adopts known technology.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because at the drive motor described in this scheme is the frequency control motor that adopts, there are a controller and two or four frequency converters of controlling each drive motor respectively in described electrical control mechanism, the right side drive motors frequency converter is controlled in the output of this controller respectively, with control left side drive motor frequency converter, the output of four rang sensors then is the input of controller.This structure, because drive motor is the frequency control motor that adopts, so the control to drive motor becomes simple, controller only needs the input according to rang sensor, the frequency converter of each drive motor power supply is given in control, just can adjust the speed of drive motor by the variation of line frequency, reach the purpose that driving wheel is not gnawed rail, greatly the structure of simplification device.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the electrical control mechanism scheme drawing of the utility model specific embodiment.
Among the figure, 1 is track, 2 is rang sensor, and 3 is driving wheel, and 4 is drive motor, 5 is retarder, 6 are the driving body, and 7 are electrical control mechanism, and K is a battery isolator control, K1 is a phase-change switch, B1 is right side two frequency converters, and B2 is left side two frequency converters, and D1 is right side two frequency control motors, D2 is left side two frequency control motors, P is a controller, and C1 is the rang sensor output of preceding right side, and C2 is the rang sensor output of preceding left side, C3 is the rang sensor output of right side, back, and C4 is the rang sensor output of left side, back.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the device of the rail travelling crane preventing gnawing rail of this programme, include the driving wheel (3) of parallel two-orbit (1) and track (1) upper support driving body (6), four drive motor (4) and the retarder (5) that have driving driving wheel (3) to rotate on the driving wheel (3), nearby square at the driving wheel (3) that driving is forward and backward, near two tracks (1) rang sensor (2) is housed, in addition, also have electrical control mechanism (7), described four drive motor of this programme (4) are the frequency control motors that adopts.Described electrical control mechanism (7) is, the three phase supply power supply is by battery isolator control (K) and phase-change switch (K1), give two frequency converters (B2) power supply of two frequency converters (B1) and supply left side two frequency control motors (D2) power supply of supply two frequency control motors in right side (D1) power supply respectively, described four frequency converters (B1) and (B2) then be the power converter of employing known technology.A controller (P) is arranged in electrical control mechanism (7), the input of this controller (P) is the output (C1), (C2), (C3) of left side and preceding four rang sensors (2) of four driving wheels in right side (3) and (C4), wherein (C1) and (C2) be the output of the rang sensor (2) of preceding two driving wheels (3) left and right sides is the output of the rang sensor (2) of two driving wheels (3) left and right sides, back (C3) and (C4).The output of controller (P) is controlled the right side respectively and is given two frequency converters (B2) of two drive motor (4) power supply usefulness for two frequency converters (B1) of two drive motor (4) power supply usefulness and control left side.When the driving ahead running, rail appears gnawing if driving is offset to the left, the rang sensor (2) of then preceding two driving wheels (3) will have output (C1) and (C2) be defeated by controller (P), controller (P) sends the frequency converter (B1) that outputs signal to right side drive motors (4) power supply according to the information of input, the output frequency of frequency converter (B1) is reduced, thereby the frequency control motor (D1) on right side is slowed down, overcome the driving phenomenon of skew operation to the left, gnaw the rail fault and eliminate thereupon, driving will normally move.Described controller (P) then is the known controller that adopts single chip machine controlling circuit.
