The spraying device effectively reduces the manual labor amount and improves the work efficiency of manual coating of rust preventive oil, and solves the problems of poor coating consistency, pollution of ballast caused by dripping rust preventive oil and waste of rust preventive oil existing in the present manual coating of rust preventive oil.

[0003] The patent application with the announcement number CN220682377U discloses a self-adaptive sensing mechanism for track bolt fastener, which specifically discloses the sensing mechanism of the above-mentioned spraying device. The sensing mechanism has the following defects in actual use: 1. The height adjusting mechanism adjusts the height by swinging, which causes the distance between the electromagnetic induction head and the nozzle to change; 2. During the rolling process of the drag-reducing wheels, foreign matters (such as stones) are easily stuck between the drag-reducing wheels, which will shield the electromagnetic induction head; 3. The electromagnetic induction head is directly exposed, and foreign matters are easily collided with the electromagnetic induction head, which causes the electromagnetic induction head to be damaged. The above-mentioned defects will cause inaccurate sensing, and further cause inaccurate oiling position, which is not easy to accurately spray the bolt fastener. Therefore, it is necessary to redesign a bolt induction mechanism of a rail bolt fastener oiling machine to solve the above-mentioned problems. SUMMARY

DETAILED DESCRIPTION

[0016] The bolt induction mechanism of the rail bolt fastener oiling machine is composed of a supporting guide rod 1, an extension rod 2, an induction piece protective sleeve 3, an electromagnetic induction head 4 and a protective single wheel 5. The extension rod 2 is movably inserted on the supporting guide rod 1, the bottom end of the extension rod 2 is threadedly installed with the induction piece protective sleeve 3, the induction piece protective sleeve 3 is threadedly installed with the electromagnetic induction head 4 (model LM18-320Na), the bolt fastener is detected through the electromagnetic induction head 4, the bolt fastener is sprayed by the spray head of the oiling machine through the detection of the electromagnetic induction head 4. The circumferential surface of the induction piece protective sleeve 3 is fixedly installed with a wheel frame 6, and the wheel frame 6 is movably installed with the protective single wheel 5. The extension rod 2 is used to drive the electromagnetic induction head 4, the wheel frame 6 and the protective single wheel 5 to ascend and descend through the lifting of the extension rod 2 relative to the supporting guide rod 1 through the induction piece protective sleeve 3, so that obstacles (raised stones, sleepers or bolt fasteners) are overcome through lifting, the electromagnetic induction head 4 can continuously move forward, and the induction can be continuously performed. Since the extension rod 2 is used to overcome obstacles through extension and lifting, the horizontal distance between the electromagnetic induction head 4 and the spray head of the oiling machine is not easily affected during the process of overcoming obstacles, the horizontal distance between the electromagnetic induction head 4 and the spray head and the advancing speed of the oiling machine can be used to accurately calculate the spraying time of the spray head, and the bolt fastener can be accurately sprayed. The induction piece protective sleeve 3 is used as a supporting piece and can protect the electromagnetic induction head 4, so that the electromagnetic induction head 4 is not easily damaged by knocking, and the electromagnetic induction head 4 can accurately detect the bolt fastener, so that the bolt fastener can be accurately sprayed. Since the protective single wheel 5 is a single roller, it is not easy to be blocked by sundries relative to a pair of resistance reduction wheels, and the electromagnetic induction head 4 is not easily shielded, so that the electromagnetic induction head 4 can accurately detect the bolt fastener.

[0017] A guide counterbore 7 is arranged on the supporting guide rod 1, and the circumferential surface of the extension rod 2 is in a stepped shape, and the thin-diameter end of the extension rod 2 is connected with the guide counterbore 7. The supporting guide rod 1 can limit and guide the extension rod 2 through the guide counterbore 7, so that the extension rod 2 can only ascend and descend and is not easy to deviate during the process of ascending and descending, and the electromagnetic induction head 4 can accurately detect, so that the bolt fastener can be accurately sprayed.

[0018] A positioning flange 8 is arranged on the supporting guide rod 1, a spring 9 is sleeved on the extension rod 2 between the positioning flange 8 and the shoulder of the extension rod 2, and the spring 9 is fixedly connected with the positioning flange 8 and the shoulder of the extension rod 2. The spring 9 is used to push the electromagnetic induction head 4 downward through the gravity of the spring 9, the extension rod 2, the induction piece protective sleeve 3, the electromagnetic induction head 4, the wheel frame 6 and the protective single wheel 5, so that the distance between the electromagnetic induction head 4 and the bolt fastener can detect the bolt fastener, and the extension rod 2 is connected with the supporting guide rod 1 through the spring 9, so that the extension rod 2 is kept connected with the supporting guide rod 1, the extension rod 2 is prevented from being separated from the supporting guide rod 1, the guiding and limiting of the supporting guide rod 1 on the extension rod 2 are kept.

[0019] The bolt induction mechanism of the rail bolt fastener oiling machine works, the oiling machine moves on the rail, the oiling machine drives the electromagnetic induction head 4 to move along the rail through the support guide rod 1, the telescopic rod 2 and the induction piece protective sleeve 3 in turn. When the electromagnetic induction head 4 moves to the bolt fastener, the electromagnetic induction head 4 induces the bolt fastener through the electromagnetic change caused by the bolt fastener. The oiling vehicle calculates the spraying time of the spraying head of the oiling vehicle according to the induction of the electromagnetic induction head 4 and the traveling speed of the oiling vehicle. After the electromagnetic induction head induces, the oiling vehicle continues to move, and the protection single wheel 5 rolls over the bolt fastener in the process. The protection single wheel 5 lifts through the wheel frame 6, the induction piece protective sleeve 3 and the telescopic rod 2 to overcome the elastic force of the spring 9, so that the induction mechanism passes over the bolt fastener and continues to move forward. When the oiling vehicle reaches the spraying time, that is, the oiling vehicle drives the spraying head to move above the bolt fastener, the spraying head sprays the bolt fastener.

[0020] The bolt induction mechanism of the rail bolt fastener oiling machine has simple structure. It avoids obstacles by lifting, and the horizontal distance between the electromagnetic induction head 4 and the spraying head of the oiling vehicle is not changed in the lifting process. It can ensure that the electromagnetic induction head 4 accurately calculates the spraying time according to the traveling speed and the distance between the electromagnetic induction head 4 and the spraying head of the oiling vehicle after the induction of the bolt fastener, so as to accurately spray the bolt fastener. At the same time, the electromagnetic induction head 4 is arranged in the induction piece protective sleeve 3, which protects the electromagnetic induction head 4 and prevents the electromagnetic induction head 4 from being damaged by collision. In addition, the bottom end of the electromagnetic induction head 4 is not easy to be clamped with sundries, which can ensure that the electromagnetic induction head 4 can accurately induce and further accurately spray. It solves the problem that the existing induction mechanism is not accurate, which leads to inaccurate oiling position and is not easy to accurately spray the bolt fastener.
