[0022] Build double-layer filling frame for yellow phosphorus filling, yellow phosphorus tank truck can directly enter the below of filling frame, and staff moves to filling frame by staircase, then according to the height of yellow phosphorus tank truck, the contraction of servo motor cylinder 1 is controlled, and then lifting platform 2 is driven to move downwards, so that lifting platform 2 moves to the top of yellow phosphorus tank truck, after lifting platform 2 operates stably, staff can move from filling frame to lifting platform, and yellow phosphorus is filled in yellow phosphorus tank truck, after filling, staff climbs out of lifting platform 2 by ladder fixed on the side of lifting platform 2 to filling frame, finally lifting platform 2 is controlled to rise, and the loading work of yellow phosphorus tank truck is completed.

[0023] As Figure 1 and Figure 2 shown, the top of lifting platform 2 is horizontally fixedly installed with connecting beam 3, the output end of servo motor cylinder 1 is fixed to the bottom surface of the end portion of connecting beam 3, and the two sides of lifting platform 2 are both arranged with servo motor cylinder 1 in pairs. Two connecting beams 3 are horizontally fixedly installed on the top of lifting platform 2, and one servo motor cylinder 1 is arranged at the end portion of connecting beam 3, the height adjustment of lifting platform 2 is finally realized by driving connecting beam 3 through the telescopic adjustment of servo motor cylinder 1.

[0024] As Figure 1 and Figure 2 shown, the two ends of lifting platform 2 are vertically fixedly connected with connecting rod 5, and are fixedly connected with the end portion of connecting beam 3 through connecting rod 5, and connecting beam 3 is I-shaped steel. Connecting beam 3 adopts I-shaped steel, so as to ensure the strength of connecting beam 3, and lifting platform 2 is directly connected with the end portion of connecting beam 3 through connecting rod 5, so as to avoid the bending deformation of the middle portion of connecting beam 3 due to stress, and further improve the stability of lifting platform 2.

[0025] As Figure 1 and Figure 2The mounting seat is movably arranged with a limiting slot through which the connecting rod 5 passes, and opposite side walls of the connecting beam 3 are in contact with opposite inner side walls of the limiting slot, and the outer side wall of the connecting beam 3 is in rolling connection with the outer side wall of the limiting bearing 4. The connecting rod 5 is vertically fixed on the lifting platform 2, and the limiting slot is matched with the connecting rod 5 on the mounting seat to limit the connecting rod 5, ensure the movement of the connecting rod 5 in the vertical direction, and further ensure the stability of the movement of the lifting platform 2; and the contact mode of the limiting bearing 4 and the connecting rod 5 is rolling friction, which can slow down the wear of the connecting rod 5. In addition, corresponding mounting seats and limiting bearings 4 can also be installed on the adjacent two outer sides of the connecting rod 5, so that the two outer side walls of the connecting rod 5 are respectively in rolling connection with the two limiting bearings 4. The ladder is vertically fixed and installed on the lifting platform 2 and arranged on one side of the connecting rod 5, and the bottom and middle of the ladder are connected to the guardrail 8.

[0026] As shown in Figures 1-3 The anti-collision assembly includes an anti-collision rod 7 horizontally hung below the lifting platform 2, the lifting platform 2 is provided with the anti-collision rod 7 on both sides, and the lifting platform 2 is provided with a limit switch 11 triggered when the anti-collision rod 7 contacts the bottom surface of the lifting platform 2. During the descending process of the lifting platform 2, since the staff controls on the ground or the filling rack, the gap between the lifting platform 2 and the yellow phosphorus tank vehicle cannot be accurately controlled, therefore, the anti-collision rod 7 contacts the top end of the yellow phosphorus tank vehicle, and then, as the lifting platform 2 continues to descend, the anti-collision rod 7 is stopped by the yellow phosphorus tank vehicle and cannot move downward, and finally, when the anti-collision rod 7 contacts the bottom surface of the lifting platform 2, the limit switch 11 is triggered, the limit switch 11 transmits a signal, and the servo electric cylinder 1 is immediately stopped.

[0027] As shown in Figure 2 and Figure 3 The lifting platform 2 is vertically fixed with a guide sleeve 9 at the bottom of the side wall, the connecting pin 10 is vertically and slidingly installed in the guide sleeve 9, the bottom end of the connecting pin 10 is fixedly connected to the anti-collision rod 7, and the limit switch 11 is arranged above the connecting pin 10. The guide sleeve 9 is used for limiting the horizontal position of the connecting pin 10, so that the anti-collision rod 7 fixedly connected with the connecting pin 10 can only move in the vertical direction, and in addition, the installation of the connecting pin 10 is also more convenient.

[0028] As shown in Figure 3The lifting platform 2 is provided with a limiting switch 11, a guide sleeve 9, an anti-collision rod 7 and a connecting pin 10. The anti-collision rod 7 is provided with a guide sleeve 9, and the guide sleeve 9 is fixedly connected with the connecting pin 10. The connecting pin 10 is fixedly connected with the lifting platform 2. The lifting platform 2 is provided with a mounting block 6, and the limiting switch 11 is connected to the top of the side wall of the mounting block 6. The bottom of the mounting block 6 is connected with the top end of the connecting pin 10 and the lifting plate 12. The bottom end of the lifting plate 12 is vertically and slidingly connected to the mounting block 6. When the anti-collision rod 7 contacts the bottom surface of the lifting platform 2, the contact of the limiting switch 11 is pressed by the lifting plate 12. Before the anti-collision rod 7 contacts the yellow phosphorus tank car, the anti-collision rod 7 is connected with the lifting plate 12 through the connecting pin 10. Due to the setting of the guide sleeve 9, the connecting pin 10 cannot move in the horizontal direction, so that the anti-collision rod 7 is in the lifting state through the lifting plate 12 in the normal state. When the anti-collision rod 7 is lifted, the lifting plate 12 is pushed along the vertical slot in the mounting block 6 through the connecting pin 10. In the process of upward movement of the lifting plate 12, the anti-collision rod 7 contacts the lifting platform 2, and the lifting plate 12 contacts the limiting switch 11 and stops the movement of the lifting platform 2.
