[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] refer to Figure 1 to Figure 9 The first aspect of the present invention protects a container centering loading device, which includes a cross beam 21. The cross beam 21 is convenient for connection with a lifting vehicle. Compared with directly connecting with the lifting vehicle through cables, the cross beam 21 has high stability when clamping and carrying containers.

[0048] The cross beam 21 is connected to the steering member 25 through the first cable member 26. The steering member 25 can move in the vertical direction. A first clamping plate member 23 is slidably provided on the steering member 25. The first clamping plate member 23 can move along the first axis direction to approach or move away from the railway flatbed car, and the first clamping plate member 23 can be clamped on both sides of the railway flatbed car. The first axis direction is the horizontal direction.

[0049] The cross beam 21 is connected to the second clamping plate member 24 through the second cable member 27, and the steering member 25 is arranged on the second clamping plate member 24, and the second clamping plate member 24 can fit with the right angle end of the railway flatbed car;

[0050] The cross beam 21 is connected to the box member 22 via a third cable member 28 , and the box member 22 can move along the direction of the second cable member 27 .

[0051] The present invention sets a first clamping plate 23, which can be close to and clamped on both sides of the railway flatbed car. At this time, the first clamping plate 23 can achieve the first positioning. Clamping on both sides of the railway flatbed car can ensure that the axis of the first clamping plate 23 is parallel to the side of the railway flatbed car that is not clamped.

[0052] Since the first clamping plate 23 is slidably arranged on the steering member 25, the steering member 25 can also be close to the railway flatbed car. Similarly, since the steering member 25 is arranged on the second clamping plate 24, the second clamping plate 24 can also be close to the railway flatbed car, so that the second clamping plate 24 can be clamped on the right angle end more accurately. At this time, the second clamping plate 24 realizes the second positioning, and the second clamping plate 24 can be accurately clamped on the right angle end through the position guidance of the first clamping plate 23.

[0053] By setting the second cable member 27, the box clamping member 22 can move along the direction of the second cable member 27. Since the second clamping plate member 24 is already engaged on the right-angle end, the box clamping member 22 clamps the container and also loads the container centrally on the railway flatbed car along the direction of the second cable member 27, thereby achieving central loading.

[0054] The centering loading device of the present invention has the following steps when working:

[0055] In the first step, after the container clamping member 22 clamps the container, the first clamping plate member 23 is extended toward the railway flatbed car. After the extension, the steering member 25 is adjusted in the vertical direction and the first clamping plate member 23 is adjusted in the first axis direction, so that the first clamping plate member 23 is clamped on both sides of the railway flatbed car;

[0056] In the second step, since the first clamping plate 23 is clamped on the railway flatbed car, the initial limit has been made, so that the steering member 25 can approach the railway flatbed car along the direction defined by the first clamping plate 23. At this time, the second clamping plate 24 can further clamp the right-angle end and can further accurately locate the position of the right-angle end;

[0057] The third step is to retract the first clamping plate 23 to expose the upper surface of the railway flatbed car, and only clamp the second clamping plate 24 at the right angle end;

[0058] In the fourth step, the second clamping plate member 24 is connected to the second cable member 27, and the container clamping member 22 falls along the second cable member 27, so that the container falls on the railway flatbed car in the center.

[0059] refer to Figure 2 In a specific embodiment, the first clamping plate 23 includes a first rack 233, and the first rack 233 is arranged along the second axis direction, and the second axis direction is also a horizontal direction and the second axis direction is perpendicular to the first axis direction. The first axis direction and the second axis direction are both horizontal directions, and both are perpendicular to the vertical direction.

[0060] Two first sliders 231 are sleeved on the first rack 233, and a horizontal gear 232 is provided on the first slider 231. The horizontal gear 232 refers to a gear that can drive the first slider 231 to move in the horizontal direction. The horizontal gear 232 can drive the two first sliders 231 to move closer to or away from each other. The first slider 231 is arranged on the steering member 25. The first slider 231 is relatively long in the vertical direction. A through hole is provided on the upper part of the first slider 231 and sleeved on the first rack 233. The inner side of the bottom of the first slider 231 is used to contact the flat side wall of the railway flatbed car.

[0061] In this embodiment, by setting the first rack 233, when working, the first rack 233 is first placed on the surface of the railway flatbed car, and the axis of the first rack 233 may have an angle with the axis direction of the railway flatbed car. Then, the first slider 231 moves toward each other to contact the side wall of the railway flatbed car. During the clamping process, the first rack 233 can be straightened so that the axis of the first rack 233 and the axis of the railway flatbed car have an angle of 0°.

[0062] In a specific embodiment, a permanent magnet is provided on the bottom wall of the first rack 233, which is not shown in the figure. The permanent magnet is provided at the midpoint of the first rack 233. A permanent magnet is provided on the bottom surface of the first rack 233. The magnetism of the permanent magnet is relatively weak and can provide partial magnetism. The permanent magnet is provided at the center of the first rack 233, i.e., the middle position.

[0063] In this embodiment, a permanent magnet is provided on the bottom surface of the first rack 233. After the permanent magnet is provided, the first rack 233 can be easily magnetically attracted to the surface of the railway flatbed car to prevent the first rack 233 from shaking, especially in a windy environment. The purpose of providing the permanent magnet in the middle of the first rack 233 is to facilitate the deflection and angle adjustment of the first rack 233 when the first slider 231 moves toward each other.

[0064] refer to Figure 2 In a specific embodiment, the second clamping plate 24 includes a slat 242, which is arranged along the second axis direction, and two second sliders 241 are slidably arranged on the slat 242, and a right-angle groove is arranged on the side of the second slider 241 close to the railway flatbed car, and the right-angle groove can fit with the right-angle end. The right-angle groove is arranged on the opposite side of the two second sliders 241, and the two right-angle grooves fit with two adjacent right-angle ends respectively, so that the second slider 241 can be fixed at the right-angle end.

[0065] A second rack 243 is vertically disposed on each second sliding block 241, and the steering member 25 is disposed on the second rack 243. The second rack 243 is disposed at an end away from the right-angle groove.

[0066] In this embodiment, the steering member 25 is arranged on the second rack 243, and the first slider 231 on the steering member 25 has been preliminarily positioned so that the width of the steering member 25 is the same as the length of the railway flatbed car. When the steering member 25 drives the second slider 241 to approach the railway flatbed car, the right-angle groove can be matched with the right-angle end to achieve precise positioning.

[0067] refer to Figure 2 In a specific embodiment, the steering member 25 includes a third slider 251, which is sleeved on the second rack 243. The third slider 251 is provided with a vertical gear 252, which refers to a gear that can drive the third slider 251 along the vertical direction. The vertical gear 252 can drive the third slider 251 to move in the vertical direction; the third slider 251 is provided with a guide rod 253, and the guide rod 253 is provided with the first slider 231.

[0068] In this embodiment, the guide rod 253 is provided to enable the first slider 231 to move along the guide rod 253. When the first slider 231 is clamped on both sides of the railway flatbed car, the guide rod 253 can drive the third slider 251 to approach the first slider 231 through the reaction force, thereby enabling the second slider 241 to approach the right-angle end, thereby achieving the fit between the right-angle groove and the right-angle end.

[0069] refer to Figure 1 , 3 ~9 any one, in a specific embodiment, the box clamp 22 includes an L-shaped frame 221, and a pulley block 223 is provided on the outer side of the vertical beam of the frame 221, and the second cable member 27 passes through the pulley block 223. Among them, the frame 221 has a top short cross beam and a vertical beam, and the side of the vertical beam close to the short cross beam is the inner side, and the side of the vertical beam away from the short cross beam is the outer side.

[0070] There are two purposes for setting the pulley block 223 in this embodiment. The first is to reduce friction so that the second cable member 27 can be retracted and released more smoothly; the second is to limit the position so that the bottom of the second cable member 27 can remain vertical, so that the straight line where the intersection edges of the two groove surfaces in the right-angle groove in the second slider 241 are located can fall on the inner side surface of the vertical beam, which is convenient for accurately centering the container.

[0071] refer to Figure 2 , 6 Or 7, in a specific embodiment, a right-angled fixing member 222 is provided on the inner side of the vertical beam of the frame 221, and the fixing member 222 assists in fixing the container. The fixing member 222 can be selected as a conventional angle iron. When the second cable member 27 is tightened, the straight line where the intersection of the two faces of the angle iron is located coincides with the straight line where the intersection of the two groove faces in the right-angle groove is located, so that the container can be accurately placed on the railway flatbed car.

[0072] The present embodiment has two functions by setting the fixing part 222. The first function is to assist in fixing the container at the side, thereby increasing the lateral stability and enabling the container to be stably clamped in the frame 221 even in windy weather. The second function is to limit the position, so that the vertical edge of the container in the fixing part 222 can accurately fall at the right angle end, thereby achieving center loading of the container.

[0073] refer to Figure 6 In a specific embodiment, an electromagnet is provided inside the fixing member 222. By providing the electromagnet, the container can be further fixed to prevent the container from shaking; in addition, after the electromagnet absorbs the container, the vertical edge of the container inside the fixing member 222 can be closely attached to the fixing member 222, so that the container can be loaded on the railway flatbed car in the center.

[0076] The second cable member 27 includes a second cable box 271 and a second cable body 272 . The second cable box 271 can store and retract the second cable body 272 .

[0077] The third cable member 28 includes a third cable box 281 and a third cable body 282 . The third cable box 281 can retract and release the third cable body 282 .

[0078] The first cable box 261, the second cable box 271 and the third cable box 281 are all conventional products on the market, which can realize the retraction and extension of the cable. The first cable box 261, the second cable box 271 and the third cable box 281 are all arranged on the top surface of the crossbeam 21. The first rope body 262, the second rope body 272 and the third rope body 282 are cables.
