[0002] From the completion of production to the full delivery to the user, the transportation of the whole vehicle is inevitably involved. At present, due to the influence of many factors such as the customer's regional policy and distance, the transportation of the whole vehicle is usually achieved by road transportation, ship transportation and other means. However, no matter which of the above methods is used, the whole vehicle needs to be bundled and hoisted onto the transportation tool. In order to ensure the absolute safety of the hoisting and transportation process, the vehicle bogie must be absolutely connected and fixed to the vehicle body. Since there are currently multiple types of vehicles to be transported at the same time, affected by the body structure of different types of vehicles, the connection device of a single type of vehicle is difficult to apply to various models. If different connection devices are customized for different models, various components are easily confused during on-site assembly, which brings great trouble to the operators. In addition, the current connection devices are generally one-time designs, which are difficult to dismantle in a non-destructive way, so they cannot be used again, resulting in a lot of material waste and low economic benefits. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies in the prior art and to provide a multifunctional connecting device suitable for railway freight car hoisting. The multifunctional connecting device suitable for railway freight car hoisting utilizes the clamp-type clamping principle to implement clamping through the deadweight of the hung object, and automatically repairs small-size deviations of the center of gravity through the rotation of the hook and the rotating shaft to ensure hoisting safety. The device is suitable for connecting various types of traction beams such as H-shaped steel, B-shaped steel, and I-shaped steel with bogies, and when dismantling, the device can be removed as a whole by loosening the hanging ring and the axle. The operation is relatively simple and the device can be used again next time.

[0029] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0030] Figure 1 A schematic structural diagram of a multifunctional connection device suitable for railway freight car hoisting according to an embodiment of the present invention is shown; Figure 2 A side view of a multifunctional connection device suitable for railway freight car hoisting according to an embodiment of the present invention is shown; Figure 3 A schematic structural diagram of a lower jaw plate of a multifunctional connection device suitable for railway freight car hoisting according to an embodiment of the present invention is shown; Figure 4 A schematic diagram of the use of a multifunctional connecting device suitable for hoisting a railway freight car according to an embodiment of the present invention is shown.

[0031] like Figure 1-4 As shown, a multifunctional connection device suitable for lifting railway freight cars comprises:

[0032] A mandibular plate 1, one end of which is provided with a through hole 1.1, and the other end of the mandibular plate 1 is inclined upward;

[0033] The upper pressing plate 2 includes a hook portion and a connecting portion, wherein the hook portion is arranged at the upper end of the connecting portion, and the lower end of the connecting portion is rotatably connected to the middle portion of the mandibular plate 1;

[0034] A rotating shaft 3, the rotating shaft 3 is rotatably connected in the through hole 1.1, and both ends of the rotating shaft 3 are exposed on both sides of the through hole 1.1;

[0035] The hanging ring 4 is U-shaped, and two ends of the hanging ring 4 are detachably connected to two ends of the rotating shaft 3.

[0036] Specifically, one end of the upper pressure plate 2 is rotatably connected to the lower jaw plate 1, so that the other end of the upper pressure plate 2 and the lower jaw plate 1 can form a scissors structure that is engaged with the beam of the railway freight car. The installation and disassembly are simple, and the multifunctional connecting device is fixed. The hanging ring 4 is connected to the lower jaw plate 1 through the rotating shaft 3, and the rotating shaft 3 is rotatably connected to the through hole 1.1 to ensure that the hanging ring 4 is vertically force-connected to the axle, thereby improving the overall safety of use.

[0037] Furthermore, the overall length of the hanging ring 4 can be flexibly customized according to different needs, which greatly reduces the difficulty of on-site assembly and differentiation to a certain extent.

[0038] In this embodiment, the hanging ring 4 includes two connecting rods and an arc-shaped portion. The two connecting rods are respectively arranged at both ends of the arc-shaped portion. One end of the two connecting rods away from the arc-shaped portion passes through the rotating shaft 3 and is exposed. The exposed end of the connecting rod is threadedly connected with a double anti-loosening nut 5.

[0039] Specifically, the hanging ring 4 and the rotating shaft 3 are fixedly connected by the nut 5, so as to facilitate installation, use and adjustment of the tightness of the hanging ring 4.

[0040] In this embodiment, the mandibular plate 1 comprises a first part and a second part, an angle is formed between the first part and the second part, and the through hole 1.1 is arranged at an end of the first part away from the second part.

[0041] In this embodiment, the upper pressing plate 2 includes two upper pressing plates 2.1, the lower jaw plate 1 is located between one ends of the two upper pressing plates 2.1, and the other ends of the two upper pressing plates 2.1 are provided with horizontal contact plates 2.2.

[0042] Specifically, the force bearing area is increased by the contact piece 2.2. (The contact area is increased to prevent indentations from being left on the action surface of the product, but the lower jaw plate cannot be provided with a contact piece to prevent interference caused by rotation when the device is removed.)

[0043] In this embodiment, a round pin 6 is further included, one end of which passes through the two upper pressing plates 2.1 and the lower jaw plate 1 and is exposed, and a cotter pin and a washer are passed through the exposed end of the round pin 6.

[0044] Specifically, the round pin 6, the washer, and the cotter pin cooperate to facilitate the rotational connection between the lower jaw plate 1 and the upper pressure plate 2, and are convenient for separation, carrying, and on-site assembly and use.

[0045] Furthermore, after disassembly, only the cotter pin needs to be replaced and other parts can be reused, thus saving costs.

[0046] In this embodiment, a buffer layer is provided on the arc portion.

[0047] Specifically, the buffer layer prevents the hanging ring 4 from wearing the axle.

[0048] In this embodiment, one end of the hook portion close to the contact piece 2.2 is perpendicular to the contact piece 2.2.

[0049] In this embodiment, a bearing is arranged in the through hole 1.1.

[0050] Specifically, the lubrication of the rotating shaft 3 and the through hole 1.1 is improved by the bearing, so as to avoid the rotating shaft 3 and the through hole 1.1 from getting stuck, and the risk of the rotating shaft 3 moving can also be overcome.

[0051] In this embodiment, it also includes a connecting plate 7 and two connecting pins. Two multifunctional connecting devices suitable for lifting railway freight cars are respectively arranged on both sides of the axle. First connecting holes are arranged at both ends of the connecting plate 7, and a second connecting hole 1.2 is arranged at one end of the second part away from the first part. One end of the connecting pin passes through the first connecting hole and the second connecting hole 1.2.

[0052] Specifically, the multifunctional connecting devices suitable for railway freight car hoisting on both sides of the axle are fixed in an associated manner through the connecting plate 7 to improve stability.

[0053] This embodiment is suitable for the use of a multifunctional connection device for lifting railway freight cars. Taking assembly as an example, the upper pressure plate 2 and the lower jaw plate 1 are connected by round pins 6 and cotter pins, and then the upper pressure plate 2, the lower jaw plate 1 and the round pin 6 assembly are inserted into the traction beam wing plate of the railway freight car to be transported, ensuring that the contact plate of the upper pressure plate 2 and the clamping point of the lower jaw plate 1 are in close contact with the upper and lower planes of the traction beam wing plate, and the lower jaw plate 1 is connected and prevented from loosening by screwing in the anti-loosening double nut 5 until the hanging ring 4 is completely in close contact with the bogie axle. (After inserting the rotating shaft, the hanging ring is selectively connected according to the height of the axle and the traction beam wing edge)

[0054] The bite force of the upper pressure plate 2 and the lower jaw plate 1 on the traction beam wing plate is transmitted by the rotating shaft 3 from the deadweight of the bogie. At this time, the lower jaw plate 1 will be driven to rotate around the connection hole between the upper pressure plate 2, and finally the lower jaw plate 1 will be completely close to the lower plane of the traction beam wing plate, and the upper pressure plate 2 will also press the upper surface of the traction beam due to the vertical force. This rotation also gives the device the ability to be applied to different types of traction beams. The connection hole between the rotating shaft 3 and the lower jaw plate 1 compensates for the deviation caused by the load-bearing rotation of the lower jaw plate 1, ensuring that the hanging ring 4 is always perpendicular to the force of the axle, ensuring the overall safety of use.

[0055] For different types of trucks, due to the large differences in the types of traction beams configured, such as: currently there are mainly traction beams such as B-shaped steel, H-shaped steel, I-shaped steel, and steel plate welded steel, when implementing the fixing operation, the lower plane of the upper pressure plate 2 must first be closely attached to the upper plane of the steel used in the traction beam, and then the lower jaw plate 1 must be rotated to be close to the lower wing surface of the traction beam. Due to the influence of the shape of the wing plate of the traction beam steel, at this time, if the hanging ring 4 is directly connected, it may cause a certain inclination angle with the axle to be connected, and the overall force condition of the connecting device will be greatly affected, which is prone to safety hazards. By installing a rotatable shaft 3, the deviation caused by the shape of the wing plate can be compensated by rotation, so that the hanging ring 4 is always perpendicular to the axle to be connected. The vertical transmission of force during vertical lifting is guaranteed, and this structure, within the load-bearing capacity of the rod, the heavier the deadweight of the connected device, the stronger the ability of the upper pressure plate 2 and the lower jaw plate 1 to bite the lower wing plate of the traction beam, and the higher the lifting safety factor. In addition, during the lifting process, if there is a certain risk of lifting tilt due to the vehicle's own settings, the device can also compensate for the resulting force offset problem by rotating the shaft 3 on the lower jaw plate 1. If it is evaluated that during the lifting process, the lifting height is large or there is a large shake during shipping, it is very easy to have a large offset or shake. At this time, a reinforced connecting plate can be installed between the reserved holes on the inner side of the lower jaw plate 1 of the device on the left and right sides of the same axle for left-right associated fixation to ensure safety in use.

[0056] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
