Abstract
The utility model relates to a shuttle car repair device, and in particular relates to a shuttle car wheel end speed reducer test device. The test device solves the problems of low repair efficiency and difficult quality guarantee of a wheel end speed reducer in the prior art. The shuttle car wheel end speed reducer test device comprises three parts of mechanical control, PLC and a hydraulic system. The mechanical control part comprises a fixation frame. A frequency conversion motor and a steering cylinder are arranged on the fixation frame. The frequency conversion motor is connected with a cross universal coupling shaft. The steering cylinder is connected with a steering connecting seat. The frequency conversion motor is connected with a frequency converter. The frequency converter is controlled by PLC. The hydraulic system comprises a power supply and a pump station and is connected with a hydraulic pipeline. The hydraulic pipeline is connected with the steering cylinder through a two position two way valve. According to the utility model, operation, noise, seal oil leakage, temperature condition and various rotation movements of the speed reducer are checked through test; the work efficiency of shuttle car repair is greatly improved; and the repair cycle is shortened.
Description
Technical field
The utility model relates to shuttle car repair apparatus, is specially a kind of shuttle road wheel end testing device for reducer.
Background technology
Shuttle car is a kind of transportation equipment conventional in mining, and utilization rate is high, often easily damages.When repairing shuttle road wheel end speed reduction unit, the wheel end speed reduction unit of repairing must shuttle car whole machine installation well after no-load test, if there is repair a breakdown, only have wheel end speed reduction unit is dismantled to handling failure from large frame, and then test again to installing on large frame, and must test by four chaptrel ends simultaneously, cause production efficiency low, waste of manpower, material resources.The component inspection of end speed reduction unit will be taken turns in ，Ruo ground without shuttle car in addition, because not having condition to test, just can not guarantee repairing quality completely.
Summary of the invention
The utility model is repaired the problem of the low and difficult quality guarantee of efficiency in order to solve the wheel end speed reduction unit that exists in prior art, a kind of shuttle road wheel end testing device for reducer is provided.
The utility model is to adopt following scheme to realize: a kind of shuttle road wheel end testing device for reducer, comprises mechanical control, PLC, hydraulic system three parts; Machinery control section comprises fixed frame, on fixed frame, be provided with variable-frequency motor, steering cylinder, is connected with cross universal coupling spindle on variable-frequency motor, be connected with and turn to Connection Block on steering cylinder, described variable-frequency motor is connected with frequency converter, frequency converter is controlled by PLC, and hydraulic system comprises power supply, pumping plant, connect fluid pressure line, fluid pressure line is connected with steering cylinder by 2/2-way valve.
During use, wheel end speed reduction unit is placed on fixed frame, then by cross universal coupling spindle and its connection, then open variable-frequency motor, variable-frequency motor drives its rotation, each action form by analog wheel end speed reduction unit on shuttle car and state are checked the repairing quality of wheel end speed reduction unit, by the running of test check speed reduction unit, noise, oil leak, temperature conditions and various revolution, move, improved greatly the efficiency that shuttle car is repaired, shortened the repair cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
In figure: 1, variable-frequency motor 2, cross universal shaft coupling 3,2/2-way valve 4, fluid pressure line 5, steering cylinder 6, wheel are held speed reduction unit 7, turned to Connection Block 8, cable 9, high-pressure rubber pipe 10, fixed frame.
Embodiment
As schematically shown in Figure 1, 2, a kind of shuttle road wheel end testing device for reducer, comprises mechanical control, PLC, hydraulic system three parts; Machinery control section comprises fixed frame 10, on 10 of fixing machines, be provided with variable-frequency motor 1, steering cylinder 5, is connected with cross universal coupling spindle 2 on variable-frequency motor 1, be connected with and turn to Connection Block 7 on steering cylinder 5, described variable-frequency motor 1 is connected with frequency converter 11, frequency converter 11 is controlled by PLC, and hydraulic system comprises power supply 13, pumping plant 12, fluid pressure line 4, fluid pressure line 4 is connected with steering cylinder 5 by 2/2-way valve 3.
Adjusting by PLC to frequency converter frequency, can set its range of adjustment is 0-60HZ, by variable-frequency motor, cross universal shaft coupling, can realize rotatablely moving of wheel end speed reduction unit, frequency converter is exported different frequencies, variable-frequency motor is just exported different speed, and wheel end speed reduction unit has different output speeds equally.The frequency change of frequency converter has just been controlled the output speed of wheel end speed reduction unit like this.We adopt PLC technology to control the frequency of frequency converter.
The gyration of wheel end is handled 2/2-way valve by hydraulic system, by steering cylinder is flexible, realizes.
Speed and rotating running status while travelling on road by simulation shuttle car, test wheel end, also can realize automatic speed regulation simultaneously and control.
technical characterstic:
1, adopt various speed and revolution running status mechanical, electrical, the complete analog wheel end of liquid technology speed reduction unit.
2, frequency converter has been realized and has been controlled stable speed changing function.
3, utilization PLC technology has realized regular speed change, nobody controls frequency converter.
4, realized the new technological flow of separate unit wheel end test.
5, the fixed frame of this device is improved, be equally applicable to the test of other speed reduction unit.
