Technical Field

The invention belongs to the technical field of steel rail quality detection, and particularly relates to an intelligent water-saving device of a steel rail flaw detection trolley.

Background

At present, steel rail flaw detection mainly depends on ultrasonic waves for detection, air between a probe and a steel rail must be removed by means of a coupling agent if the ultrasonic waves sent by the probe enter the steel rail smoothly, water with relatively low price is generally selected as the coupling agent in the actual detection process, a water tank with a certain volume is required to be arranged on a flaw detection trolley, and the water tank is arranged on a water pipe to provide coupling water for each probe on an instrument in a shunting manner.

However, in the process of detecting the steel rail, the pushing speed of the flaw detection trolley is not consistent, generally, the pushing speed of the flaw detection trolley is not matched with that of a jointless track section, namely, 3km/h, 2km/h and 1km/h, of a seamed track section, so that the problem that the water supply speed is not matched with that of the pushing speed exists, for example, in the jointless track section, the water supply is insufficient due to the high pushing speed of the flaw detection trolley, the water supply is sufficient but the water quantity is wasted in the joint section, although a water valve is arranged below a water tank to control the flow speed of water, the water valve depends on manual adjustment, the time is wasted, the operation is troublesome, and in addition, the manual adjustment precision cannot be matched with the speed of the.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides the intelligent water-saving device for the steel rail flaw detection trolley, which is purely mechanically controlled, can realize the matching of the water yield and the speed of the flaw detection trolley, and is convenient and quick to operate.

The technical scheme of the invention is as follows: the utility model provides a rail flaw detection dolly intelligence water saving fixtures, including dolly walking wheel and water tank, a water control device who is the cylinder is installed to the water tank below, water control device has one on the cylinder wall and intakes end and goes out the water end, water control device center pin department is equipped with the pivot, be fixed with two at least blades in the pivot, the blade free end extends to water control device's drum inner wall, be equipped with the drive mechanism that can transmit the rotary power of dolly walking wheel to the pivot between pivot and the dolly walking wheel, drive mechanism drives the pivot rotation.

The further technical scheme of the invention is as follows: the transmission mechanism comprises a walking gear coaxially arranged with the trolley walking wheel, a transmission gear in meshing transmission with the walking gear, a conical transmission gear coaxially arranged with the transmission gear and a conical steering gear in meshing transmission with the conical transmission gear, wherein a transmission rod is connected to the central shaft of the conical steering gear, and the transmission rod is coaxially connected with the rotating shaft.

The further technical scheme of the invention is as follows: the blades on the rotating shaft are uniformly arranged around the rotating shaft.

The further technical scheme of the invention is as follows: the number of the blades is 6-12.

The further technical scheme of the invention is as follows: the water outlet end of the water quantity control device is connected with a plurality of water pipes.

Compared with the prior art, the invention has the following characteristics:

1) the transmission mechanism is arranged to transmit the rotating power of the trolley travelling wheel to the rotating shaft so as to drive the blades to rotate, so that water flow in the water tank is supplied to the water outlet end along with the rotation of the blades, the water flow speed and the water outlet amount are finally determined by the trolley speed, namely the water outlet amount is matched with the trolley speed, the problem of excessive or insufficient water outlet can not occur, water is effectively saved, and the water supply is ensured;

2) the transmission mechanism has an exquisite and simple overall structure, and smoothly links the trolley travelling wheels with the rotating shaft;

3) the blades are uniformly arranged around the rotating shaft and are more in number, water flow falling into the water quantity control device from the water tank is finely divided, the water quantity between every two blades is less, and the water quantity discharged from the water outlet end of the water quantity control device at each time is the water quantity between the two blades along with the rotation of the blades, so that the water quantity and the water speed can be reasonably distributed and controlled;

4) the water-saving device has a powerful water-saving function, so that the detection operation mileage of the trolley every time is longer, and water is not required to be frequently supplemented to the water tank;

5) the whole course water yield is automatically controlled, manual adjustment is not needed, the working efficiency is high, and no manual factor interference exists.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.
