Abstract
The invention relates to improvement technology for a windscreen wiper, in particular to a control device for the swing of the windscreen wiper. The control device solves the problem that an explosion-proof motor for the windscreen wiper of an underground vehicle is difficult to select, and is applied to pneumatic control on the vehicle windscreen wipers with an air resource in various explosive gas working environments. The device is provided with an execution part and an operation part, wherein a throttle speed-regulating valve is arranged on a pipeline between the execution part and the operation part; the execution part is connected with the windscreen wiper; and the operation part is connected with a power part. In the improvement technology, the single swing of the windscreen wiper can be realized, namely the windscreen wiper is controlled to swing leftwards or rightwards by operating a hand operated valve (a two-position four-way valve). Compressed air serves as a power source; the hand operated valve serves as an operating mechanism; and the throttle speed-regulating valve is used for regulating an air flow so as to control the rotation speed of an execution mechanism (a rotation air cylinder).
Description
Technical field
The present invention relates to the improvement technology of vehicle windscreen wiper, be specially a kind of control setup of wiper swing of underground vehicle.
Background technology
For a long time, the operator's compartment of down-hole trackless rubber tire transport trolley all is an open type, does not have windshield also not need wiper, but the other noise ratio of driver's ear is higher, and the psychology and the physiology of chaufeur is produced bigger injury.If, operator's compartment is made full-enclosed structure, just can solve interference of noise.But, also having brought the problem that needs the apolegamy wiper simultaneously, automobile all is to use motor as propulsion source with wiper usually, and there is requirement of explosion the down-hole to motor, makes relatively difficulty of choice of electrical machine.
Summary of the invention
The object of the present invention is to provide a kind of control setup of vehicle windscreen wiper swing, solve the underground vehicle wiper, be applicable to the vehicle windscreen wiper air operated control that has source of the gas under the various damp working environments with the difficult problem of selecting of fire proof motor.
Technical scheme of the present invention is:
A kind of control setup of vehicle windscreen wiper swing, this device is provided with operating part and function part, on the pipeline that connects between operating part and the function part throttling governing valve is housed, and operating part connects wiper, and function part connects power pack section.
The control setup of described vehicle windscreen wiper swing, operating part is a rotation cylinder.
The control setup of described vehicle windscreen wiper swing, function part is two position switching valves.
The control setup of described vehicle windscreen wiper swing, power pack section is a pressurized air.
Operating part of the present invention is rotation cylinder but not the common motor of usefulness, and function part is pneumatic valve (two position four-way valves), and is simple, convenient.The throttling governing valve that adds a control gaseous flow in the middle of function part and operating part is controlled the velocity of rotation of rotation cylinder.Like this, control rotation cylinder or the right side swing left by handling hand valve (two commutation four-way cockes), thereby drive wiper or the right side swing left, the velocity of rotation of rotation cylinder relies on throttling governing valve regulation gas flow to control.
The invention has the beneficial effects as follows:
1, the present invention is a down-hole trackless rubber tire transport trolley wiper pendulous device with non-fire proof motor control, has reduced the use and the maintenance cost of the wiper that adopts fire proof motor control.
2, apparatus of the present invention are rational in infrastructure, and working service is convenient, can under all kinds of harsies environment, use, and working stability, be applicable to various road surfaces, mine and down-hole transport vehicle.
3, the present invention adopts pressurized air as propulsion source, with hand valve as operating mechanism, the middle velocity of rotation of controlling rotation cylinder with throttling governing valve regulation gas flow, thereby steadily swing about the realization wiper, adopt pressurized air as propulsion source, safety, environmental protection, energy savings.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
Among the figure, 1 external air source (air compressor); 2 liang of position switching valves; 3 throttling governing valves; 4 connection tracheaes; 5 rotation cylinder.
The specific embodiment
As shown in Figure 1, wiper air control unit of the present invention mainly comprises: two position switching valves 2, throttling governing valve 3, connection tracheae 4, rotation cylinder 5 etc., and concrete structure is as follows:
Two position switching valves, 2 input ends as function part connect external air source (power pack section), the mouth of two position switching valves 2 connects rotation cylinder 5 by connecting with tracheae 4 respectively, on connecting, be provided with throttling governing valve 3, as the rotation cylinder 5 connection wipers of operating part with tracheae 4.
Working process of the present invention is as follows:
External air source 1 uses tracheae 4 to two position switching valves, 2 air feed by connecting, and gas is directly supplied with rotation cylinder 5 through throttling governing valve 3, makes rotation cylinder 5 rotate the arm sheet that drives wipers and realizes rotation.If when needing commutation, pull two position switching valves 2 and make gas supply with rotation cylinder 5 through the throttling governing valve 3 of opposite side, realize the reverse rotation of arm sheet of wiper.
When outer gas is flowed through throttling governing valve 3,, control the velocity of rotation of rotation cylinder 5 with this, thereby realize the arm sheet rotation speed of control wiper by adjusting governing screw control rotation cylinder 5 charge flow rates of the bidirectional throttling valve in the throttling governing valve 3.
The result shows, the present invention can realize dust on the arm sheet cleaning front windshield glass of wiper and water dirt etc., guarantee totally, not influence on the front windshield glass driver's seat, and can be according to working environment regulated at will swing speed, to reach the effect of timely cleaning front windshield glass.
