Description

TECHNICAL FIELD

[0001] The application relates to an automatic push rod device suitable for a high-speed railway ballastless track plate mold and application thereof, and belongs to the technical field of building construction. BACKGROUND

[0002] Before demolding, a high-speed railway CRTSIII track plate needs to be manually pulled out of a tension rod, so that the front end of the tension rod is retracted to the inside of the mold, to prevent the tension end from being exposed to the inside of the mold during demolding, so that the tension rod scratches the track plate during demolding, causing damage to the appearance of the track plate and affecting the quality of the track plate product. During the manual pulling process, the tension rods are uneven and some are too long, so after the track plate is demolded, the tension rods need to be uniformly pushed into the end close to the inside of the mold to prevent the position of the pulled-out tension rod from being too long, thereby causing damage to the equipment and affecting the construction production progress. SUMMARY

The automatic pusher device is provided on one side of the track slab demolding mold 1. The automatic pusher device includes two parts: a driving part located below the foundation and an operating part located above the foundation, corresponding to the position of the track slab demolding mold 1.

[0021] The drive unit includes parallel steel plates 2, with a drive motor I3 between the steel plates 2. The output end of the drive motor I3 is connected to a reducer 4, and the output end of the reducer 4 is connected to a drive gear I5. The drive gear I5 transmits power to the working part. By rotating the drive motor I3 forward and backward, the working part can move up or down.

[0022] The working part comprises a sliding support leg 6, a sliding support leg guide column 7 is arranged below the sliding support leg 6, a lifting rack 14 is arranged on the sliding support leg guide column 7, the lifting rack 14 is in meshing connection with a driving gear I 5, the driving gear I 5 rotates to drive the lifting rack 14 to drive the sliding support leg guide column 7 to move up and down, a sliding rail 8 is arranged above the sliding support leg 6, a sliding block 9 is in sliding connection on the sliding rail 8, the movement direction of the sliding block 9 is the width direction of the sliding support leg 6, an L-shaped baffle 10 is welded on the upper end surface of the sliding block 9, the vertical part of the L-shaped baffle 10 is away from the track plate stripping die 1, and the sliding block 9 drives the L-shaped baffle 10 to move left and right along the width direction of the sliding support leg 6. The vertical part of the L-shaped baffle 10 is used to arrange the one ends of the plurality of tension rods in the same plane, so that the tension rods cannot be inserted into the track plate stripping die 1 at the same time, and manual insertion and removal of the tension rods is avoided, so that the work efficiency is improved while the labor is saved.

[0023] The tension rod can have a transverse displacement during the pushing process, and the guide plate 17 can provide a guiding effect to slowly push the tension rod in, the guide plate 17 has an outer wide and inner narrow shape, the outer wide is used to facilitate the tension rod to enter, and the inner narrow is used to make the pushing position correct.

[0024] The L-shaped baffle 10 is provided with a laser distance measuring sensor 16 at each end, which is used to monitor whether the displacement of the two ends is synchronous, and is also used to monitor the walking displacement, so that the displacement is the same each time, and the tension rod can be pushed into the appropriate position, and the model of the laser distance measuring sensor is Bonna laser distance measuring sensor LTF12.

[0025] The sliding block 9 is controlled to slide on the sliding rail 8 through a driving gear II 11 and a driving motor II 12, when it is necessary to insert the tension rod, the driving motor II 12 is started to drive the driving gear II 11 to rotate forward, and then the sliding block 9 is driven to move towards the track plate stripping die 1, so that all the tension rods enter the track plate stripping die 1 at the same time, and reach the same position at the same time, so that the tension rods are not too long to interfere with the next station equipment during the circulation, and the equipment is damaged and danger occurs.

[0026] The side of the sliding leg 6 is provided with a displacement sensor 13, which is controlled to start and stop by a control cabinet 15, and the signal of the displacement sensor 13 is also processed and analyzed by the control cabinet 15. The displacement sensor 13 adopts Mileang KPC1-1000M, and can detect the displacement state of the sliding leg 6, monitor whether the position of the sliding leg 6 rising or falling is accurate and reasonable, and when the sliding leg 6 rises, the L-shaped baffle 10 will lift and pull out the tension rod, so that the tension rod is horizontally positioned with the tension rod hole of the track plate stripping mold 1, and the tension rod is conveniently pushed into the tension hole of the track plate stripping mold 1. If the sliding leg 6 does not rise to the position, the displacement sensor 13 will alarm, so as to prevent the tension rod from being inaccurate in position and interfering with the track plate stripping mold 1 when being pushed in, causing danger or damage to the equipment. The synchronous movement of the two sliding legs 6 is realized by matching the displacement sensor 13 with the synchronizer.

When the sliding leg 6 rises to the position corresponding to the tension rod hole of the track plate stripping mold 1, that is, the L-shaped baffle 10 lifts the tension rod to the horizontal state, and the tension rod corresponds to the position of the tension rod hole of the track plate stripping mold 1, the driving motor I3 is turned off. The driving motor II 12 is started, the driving motor II 12 provides power, the driving gear II 11 is connected with the driving motor II 12, the sliding block 9 is installed on the driving gear II 11, the sliding block 9 drives the L-shaped baffle 10 to move on the sliding rail 8, and the movement direction is towards the side of the track plate stripping mold 1. In the movement process, the L-shaped baffle 10 pushes the tension rod placed in disorder into the same position of the track plate stripping mold 1, that is, the tension rod hole of the track plate stripping mold 1, and the insertion of the tension rod is completed.

[0029] Embodiment two:

[0030] When it is needed to pull out the tension rod from the tension rod hole of the track plate stripping mold 1, the driving motor II 12 is reversely rotated, the driving gear II 11 is reversely rotated, the driving gear II 11 drives the sliding block 9 to move away from the track plate stripping mold 1, and after moving to the maximum stroke, the driving motor II 12 stops working, and the L-shaped baffle 10 is back to the original position.

[0031] After the L-shaped baffle 10 is finished, the driving motor I3 is started, the driving motor I3 drives the speed reducer 4 to rotate, the speed reducer 4 matches the rotating speed and transmits the torque between the driving motor I3 and the sliding leg 6, and then the driving gear I5 and the sliding leg guide column 7 simultaneously assist the sliding leg 6 to descend, the displacement sensor 13 on one side of the sliding leg 6 monitors the displacement state in real time, prevents the descending from being not in place, interferes with the demolding mold 1 of the track plate flowing over next time, causes the equipment damage or danger, and after the sliding leg 6 is descended to the position, the sliding leg 6 is finished, the whole is finished, the equipment is completely worked, and the next mold flow is started again.
