The lower end of the short arm of the L-shaped rod 9 is provided with a wheel 10, and the wheel 10 is positioned on the track. When cement slag exists on the rail, the wheels 10 are jacked upwards under the action of the cement slag, so that the long rod rotates forwards and upwards at the same time.

The slag pusher comprises a slag pushing plate 12, a swinging rod 11 and a vibrating motor 3. The swing rod 11 inclines along the direction from front to back and downwards, the middle position of the swing rod is hinged with the vehicle body 1 of the paver, the slag pushing plate 12 inclines along the direction from back to front and downwards, the rear end of the slag pushing plate 12 is hinged with the lower end of the swing rod 11, a torsion spring (not shown in the figure) is arranged at the hinged position, and downward acting force is applied to the front end of the slag pushing plate 12 under the action of the torsion spring. The lower end of the swing rod 11 is provided with a limiting device 13, and the limiting device 13 can limit the rotation angle of the slag pushing plate 12 so that the slag pushing plate can only rotate at a small angle. A thrust spring 14 is arranged behind the lower end of the swing rod 11, and the lower end of the swing rod 11 is pushed forwards under the action of the thrust spring 14. After the lower end of the swing rod 11 is pushed out forwards by the thrust spring 14, the front end of the slag pushing plate 12 is located right below the middle hinge joint of the swing rod 11, so that the front end of the slag pushing plate 12 is located at the lowest position of the stroke, at the moment, the front end of the slag pushing plate 12 is tightly attached to the rail, and at the moment, cement slag on the rail can be removed. When the lower end of the swing lever 11 is rotated backward, the front end of the slag pushing plate 12 moves backward and also moves upward by a certain distance to be separated from the rail, thereby preventing friction from occurring between the front end and the rail. The vibrating motor 3 is fixed on the oscillating rod 11, and the cleaning effect on the cement slag can be promoted through the high-frequency vibration effect of the vibrating motor 3.

The upper end of the L-shaped rod 9 is provided with an arc ratchet bar 5, an output shaft of the band-type brake motor 6 is fixedly provided with a ratchet wheel 7, the ratchet wheel 7 and the ratchet bar 5 are meshed with each other, as shown in fig. 4, the directions of ratchets on the ratchet wheel 7 and the ratchet bar 5 meet the requirement that the ratchet bar 5 can freely swing forwards but cannot swing backwards. As shown in fig. 3, the band-type brake motor 6 is mounted on a motor plate 8, and the motor plate 8 is hinged to the vehicle body 1 at the rear end of the band-type brake motor 6. The motor plate 8 inclines along the direction from front to bottom to back, the upper end of the L-shaped rod 9 abuts against the lower side surface of the motor plate 8, when the L-shaped rod 9 rotates forwards and upwards, the motor plate 8 is driven to be lifted forwards and upwards, the ratchet wheel 7 and the ratchet rack 5 are separated from each other after the L-shaped rod 9 is lifted, and the lower end of the swinging rod 11 is pushed forwards under the thrust of the thrust spring 14 after the L-shaped rod 9 is separated from the ratchet wheel and the ratchet rack.

The rail sweeper is located behind the slag pusher and comprises a steel brush 15, an electromagnet and a vertical sliding rail 17, the vertical sliding rail 17 is fixed on the trolley body 1, the electromagnet comprises a movable electromagnet 16 and a fixed electromagnet 2, the fixed electromagnet 2 is arranged on the trolley body 1 or the vertical sliding rail 17, the movable electromagnet 16 is arranged under the trolley body, the movable electromagnet 16 is matched with the vertical sliding rail 17, and the movable electromagnet 16 and the vertical sliding rail 17 can be matched with each other and can slide up and down along the vertical sliding rail 17. The upper end of the steel brush 15 is fixed on the movable electromagnet 16. The rail sweeper can sweep cement slag and accumulated dust on the rail. After a period of time, the steel brush 15 can be abraded to a certain extent, and the lower end of the steel brush 15 can fall and compensate under the action of gravity after being abraded, and is close to the rail surface by self-weight. When the electromagnet is not electrified, the steel brush 15 and the movable electromagnet 16 are pressed on the rail by the dead weight to clean the rail, the cleaning action force is weak, and the steel brush and the movable electromagnet are used for cleaning sundry dust and cement slag with poor adhesion on the rail; when the electromagnets are electrified, the two electromagnets repel each other to exert a downward acting force on the movable electromagnet 16, at the moment, the pressure of the steel brush 15 on the track is larger, and the cleaning acting force of the steel brush 15 is stronger.

Travel switches 4 are respectively arranged below the rear part of the upper end of the L-shaped rod 9 and the rear part of the lower end of the swing rod 11, the positions of the L-shaped rod 9 and the swing rod 11 are detected through the travel switches 4, and meanwhile the on-off of relevant electrical equipment is controlled. The specific circuit connection relationship is the prior art and will not be described herein. When the upper end of the L-shaped rod 9 swings forwards and upwards, the lower end of the swinging rod 11 simultaneously pops forwards, the vibration motor 3 and the electromagnet are powered on, and the internal contracting brake motor 6 is powered off; when the L-shaped rod 9 falls back, the vibration motor 3 and the electromagnet lose power, and the band-type brake motor 6 is powered on; when the L-shaped rod 9 falls back and the lower end of the swinging rod 11 is reset backwards, the vibration motor 3, the electromagnet and the band-type brake motor 6 are simultaneously powered off.

The working principle of the invention is as follows: when no cement slag exists, the wheel 10 at the lower end of the L-shaped rod 9 is positioned on the track, the ratchet wheel 7 of the band-type brake motor 6 is meshed with the ratchet bar 5, the lower end of the swinging rod 11 is inclined backwards as shown in figure 2, the slag pushing plate 12 leaves the track, and no friction is generated between the slag pushing plate and the track; at the moment, impurities on the rail are less, the steel brush 15 falls on the rail only by the force of gravity, and the abrasion of the steel brush 15 is less in the state. When cement slag appears on the track, when the wheel 10 at the lower end of the L-shaped rod 9 presses down the cement slag, the wheel 10 is lifted up under the action of the cement slag, so that the upper end of the L-shaped rod 9 swings forwards and upwards, the ratchet wheel 7 of the band-type brake motor 6 is separated from the ratchet bar 5, the lower end of the swing rod 11 is popped forwards under the action of the thrust spring 14, the slag pushing plate 12 impacts the cement slag at a very high speed through the popping speed of the thrust spring 14 and the running speed of the paver, and the cement slag can be smashed and separated from the track. At the moment, the vibration motor 3 and the electromagnet are electrified, and the cement slag is continuously impacted by the vibration effect for the harder cement slag, so that the cement slag can be crushed; when the paver is running forwards, the hard cement slag can block the movement of the slag pushing plate 12, at the moment, the thrust spring 14 is compressed backwards for a certain distance, the slag pushing plate 12 is always pushed against the cement slag within the time range to vibrate and impact the cement slag, and the impact time can be prolonged through the design of the thrust spring 14, so that the cement slag can be removed as much as possible; in addition, the slag pushing plate 12 can rotate at a certain angle, so when the oscillating rod 11 rotates backwards at a certain angle, the lower end of the oscillating rod 11 is lifted upwards for a certain distance, and the front end of the pushing plate correspondingly falls downwards for a certain distance at the moment, so that the front end of the pushing plate can be ensured to be attached to the track and not to be separated from cement slag, and the cement slag can be impacted for a long time; for the cement slag with special hardness, the swinging rod 11 is pushed to rotate backwards by a larger angle until the pushing plate is lifted upwards to leave the cement slag, so that the damage of the cement slag with excessive hardness to the slag pusher can be avoided. Meanwhile, the electromagnet is powered to push the steel brush 15 downwards, the steel brush 15 brushes the track with large force, and residues left on the track are completely removed. When the slag pushing plate 12 meets the joint of the rail during slag removal, the slag pushing plate can be easily clamped in the gap of the joint, and the joint can push the swinging rod 11 to rotate backwards by a larger angle as hard cement slag until the front end of the slag pushing plate 12 rises upwards to be separated from the gap. When the paver runs to a road section without cement slag, wheels 10 of an L-shaped rod 9 are put down, the L-shaped rod 9 returns, a ratchet wheel 7 of a band-type brake motor 6 is meshed with a ratchet bar 5 again, at the moment, the vibration motor 3 and the electromagnet are powered off, the band-type brake motor 6 is powered on to rotate, the arc ratchet bar 5 is driven to move forwards under the action of the band-type brake motor 6, the swinging rod 11 is pulled down to rotate backwards by overcoming the elastic force of a thrust spring 14 until the swinging rod rotates to a corresponding travel switch 4, and at the moment, the band-type brake motor 6 is powered off to stop running. When the brake motor 6 is de-energized, the motor spindle can be locked to be incapable of rotating, the position of the ratchet bar 5 is fixed under the action of the brake motor 6, and the swinging rod 11 is prevented from being ejected by the thrust spring 14.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
