Abstract

Tyre detecting equipment comprises a power source (1), a full-bridge converter (2), a high-voltage transformer (3) and a half-wave voltage doubling rectifying circuit (4) and is characterized in that the power source (1), the full-bridge converter (2), the high-voltage transformer (3) and the half-wave voltage doubling rectifying circuit (4) are connected sequentially, the power source (1) is converted into alternating-current square waves through the full-bridge converter (2), the alternating-current square waves are transmitted to an input end of the high-voltage transformer (3) and connected to the half-wave voltage doubling rectifying circuit (4) after being output by the high-voltage transformer (3), and high-voltage pulse is exerted on a tyre crown and a tyre shoulder after voltage doubling rectification of the square waves. The tyre detecting equipment with the high-voltage pulse power source is smaller in size so as to save a great quantity of materials and space, is deceased by 5-10 times in size and total weight as compared with a traditional high-voltage generation device, is high in detecting accuracy, and is less in power consumption since the practical consumed power of the high-voltage pulse power source for detecting is 60W only equivalent to 10% of that of a common high-voltage direct-current power source.

Description

A kind of tire checking equipment

Technical field

The utility model relates to a kind of tire checking equipment.

Background technology

China's tire checking apparatus field almost is in the blank stage at present, tire checking equipment can not check out precisely fast whether inside tires has unfavorable conditions such as bubble, concavo-convex, dazzling position, and have bulky, power consumption is big, detect the not high defective of accuracy rate.

Summary of the invention

The purpose of this utility model provides and a kind ofly can precisely detect the equipment that tire is bubble, concavo-convex, dazzling position fast.

The technical scheme that the utility model is adopted for achieving the above object is:

A kind of tire checking equipment, comprise power supply, full-bridge converter, high-tension transformer, half-wave voltage doubler, it is characterized in that: power supply, full-bridge converter, high-tension transformer, half-wave voltage doubler connect successively, power supply becomes ac square wave by full-bridge converter, give the high-tension transformer input end ac square wave then, after high-tension transformer output, receive half-wave voltage doubler, through after the voltage multiplying rectifier high-voltage pulse is added to tyre crown and tire shoulder part.

Described half-wave rectifying circuit has 10 grades.

It is+24V that power is the Switching Power Supply of 100W that described power supply adopts voltage.

Described power supply has also designed the long-distance intelligent control interface.

The beneficial effects of the utility model are:

On the volume, bulky before having improved, a lot of materials of high-voltage pulse power source volume saving and space, general assembly (TW) also reduces 5-10 doubly than conventional high-tension generating means volume and weight; Power consumption is less, and when detecting with this pulsed high voltage generator, the power of actual consumption only has 60W, only is 10% of common high-voltage DC power supply; Detection accuracy rate height.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 2 is the utility model high tension loop figure.

Embodiment

A kind of tire checking equipment, comprise power supply 1, full-bridge converter 2, high-tension transformer 3, half-wave voltage doubler 4, it is characterized in that: power supply 1, full-bridge converter 2, high-tension transformer 3, half-wave voltage doubler 4 connect successively, power supply becomes ac square wave by full-bridge converter 2, give the high-tension transformer input end ac square wave then, after high-tension transformer 3 outputs, receive half-wave voltage doubler 4, high-voltage pulse is added to tyre crown and tire shoulder part through after the voltage multiplying rectifier.High pressure will puncture in pin hole and internal injury position, and the electric current during puncture also can make the rubber carbonization around it, produces the visible marking, thereby can detect pin hole and internal injury position on the tire by equipment.It is+24V that power is the Switching Power Supply of 100W, can reduce the high-tension transformer volume that power supply 1 adopts voltage.+ 24V power supply full-bridge converter, become the ac square wave of 50kHz, give the high-tension transformer input end ac square wave then, the no-load voltage ratio of high-tension transformer is generally about 90 ~ 120 times, after high-tension transformer output, receive half-wave voltage doubler, just can export 40 ~ 45kV high pressure later, be added to tyre crown and tire shoulder part then through voltage multiplying rectifier.Half-wave rectifying circuit has 10 grades.By the working time of control full-bridge converter, just can directly control the working time of output high pressure, make output be impulse form.

Power supply has also designed the long-distance intelligent control interface, by interface provide+the 10V reference signal, make things convenient for the user power supply precisely to be controlled by single-chip microcomputer or PLC; The monitor signal that also includes high pressure output in the remote monitoring interface makes things convenient for the user to insert numeral or analogue instrument is monitored in real time to the output of power supply; Also include the control signal of adjusting high-voltage pulse frequency, pulse width, pulse voltage in the Based Intelligent Control interface, make things convenient for the user to detect the tire of various models; Use the high insulating property material seal, reduce 5-10 doubly than conventional high-tension generating means volume and weight; High voltage control partly adopts accurate control circuit, has improved the reliability and the processing safety of power supply.Equipment has adopted convenience man machine operation interface intuitively, fully improves production work efficient.
