It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model. The technical solutions of the utility model are described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.

[0025] Referring to Figures 1 to 6 The embodiment proposes a device for preventing car transfer platform from sliding, which comprises parallel heavy car line track 9 and empty car line track 10 arranged on the ground; one side of the heavy car line track 9 and the empty car line track 10 is provided with car transfer track 8; the car transfer track 8 is perpendicular to the heavy car line track 9 and the empty car line track 10; the car transfer track 8 comprises parallel first track 81 and second track 82; the car transfer platform 3 is slidably connected on the first track 81 and the second track 82; the drive device 2 is arranged on the car transfer platform 3; the upper surface of the car transfer platform 3 is provided with platform track 31 for connecting with the heavy car line track 9 and the empty car line track 10; one side of the heavy car line track 9 and the empty car line track 10 is provided with proximity switch 6; the encoder 7 is installed on the side of the car transfer platform 3 close to the proximity switch 6, and the encoder 7 and the proximity switch 6 are linked. The car transfer platform 3 is moved to the heavy car line track 9 by the drive device 2, after the platform track 31 is aligned with the heavy car line track 9 on the ground, the track train on the heavy car line track 9 is moved to the car transfer platform 3, then the car transfer platform 3 is moved to the side of the empty car line track 10 through the first track 81 and the second track 82, after the platform track 31 is aligned with the empty car line track 10 on the ground, the track train on the car transfer platform 3 is moved to the empty car line track 10. The adjustable buffer device 4 is installed on both sides of the car transfer platform 3; the double pin electro-hydraulic push rod 5 is installed on the other two sides of the car transfer platform 3.

[0026] During the work, the problem of the car platform 3 often appears, the first to the east and west of the car platform track 8 measurement, to measure the first track 81, second track 82 elevation every 1m interval, can understand the track elevation fluctuation, because the west side of the empty car line track 10 near the slope, resulting in the west side of the empty car line track 10 overall decline larger, east and west of the car platform track 8 measured elevation difference of 70mm, the specific values are as follows:

[0027]

[0028] Note: the car platform track 8 is east high west low trend;

[0029] Track adjustment:

[0030] (1) because of the overall empty car line near the slope, the empty car line track 10 overall subsidence larger, east and west of the car platform track 8 measured elevation difference of 70mm, because of the difficulty of foundation treatment, the car platform track 8 can't be completely flat, by lowering the heavy car line track 9, the empty car line track 10 is appropriately raised, the overall high and low difference of the car platform track 8 is reduced to about 40mm.

[0031] (2) considering the adjusted car platform track 8 east and west side difference is still larger, still will occur because of the foundation settlement superimposed wind weather caused by the car platform 3, using the car platform track 8 highest point to the east side of west 2m, so that the highest point of both sides low, namely the car platform track 8 elevation is high in the middle and low at both ends, the highest point of the car platform track 8 is located between the heavy car line track 9 and the empty car line track 10; actively guide the car platform 3 to the two sides, and use the adjustable buffer device 4 on both sides of the car platform 3 to buffer and lock the position of the car platform.

[0032] .

[0033] In order to reduce the frequency of the car platform 3, the adjustable buffer device 4 is adjustable, the adjustable buffer device 4 includes a buffer column 41 and a buffer head 42; one end of the buffer column 41 is welded and fixed with the car platform 3, the other end of the buffer column 41 is connected with the buffer head 42 through the length adjusting bolt assembly. The buffer head 42 is distributed with buffer pads 43 for absorbing the buffer force, and the outer surface of the buffer pad 43 is provided with a plurality of buffer protrusions. The length adjusting bolt assembly includes a stud 44 and a nut 45; the four corners of the buffer column 41 and the buffer head 42 are connected by the stud 44 respectively; four nuts 45 are connected on each stud 44. By adjusting the stud 44 and the nut 45, the buffer device is adjustable, so that the car platform 3 actively slides, and the platform track 31 is aligned with the heavy car line track 9 or the empty car line track 10.

[0034] In order to further reduce the influence of the external environment on the migration platform 3, the wind wall 1 is arranged on both sides of the migration platform track 8.

[0035] Working principle: due to the east high and west low trend of the migration platform track 8, the migration platform 3 is passively disordered and slides, and the migration platform 3 often has a sliding problem; by adjusting the migration platform track 8 to be high in the middle and low on both sides, the migration platform 3 is actively slid to both sides, the buffer column 41 at the appropriate position is fixed, when the migration platform 3 is slid to both sides, the buffer column 41 can first hit the wall, the parking position is appropriate, and the track is aligned, so that the no sliding fault alarm condition is realized, and the unloading is normal.

[0036] The above is a further detailed description of the utility model in combination with a specific preferred embodiment, and the specific implementation of the utility model cannot be limited to this. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the utility model, a number of simple deductions or substitutions can be made, and all of them should be regarded as belonging to the utility model, and the patent protection range is determined by the submitted claims.
