Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and more specifically, to a suspension beam and a railway crane having the same. Background Art

[0002] A railway crane is a boom-type crane installed on a special chassis and capable of running along railway tracks, used for loading and unloading operations, equipment installation, and accident rescue such as railway locomotives and vehicle overturns. To avoid damaging the vehicle during vehicle rescue, a railway crane is often equipped with a suspension beam.

[0003] Currently, with the development of the international market, large-tonnage railway cranes have also started to be exported. Most of the exported railway crane products are transported by sea, loading the railway crane onto a ship for transportation.

[0004] However, the suspension shaft on the suspension beam equipped with the railway crane is used in conjunction with the hook of the crane, and the hooks on the port cranes are generally very large and cannot match the suspension shaft on the suspension beam. If directly hanging the steel wire rope on the suspension shaft, because the distance between the two suspension shafts on the suspension beam is too small, a stable structure cannot be formed, there are potential safety hazards; the additional bending moment of the suspension beam will also increase, resulting in a very large suspension beam.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figures 1 to 5As shown in the figure, the embodiment of the utility model provides a lifting beam for a railway crane. The lifting beam for the railway crane includes a beam body 10, a first lifting shaft, two lifting lugs 30, and two second lifting shafts 40. The beam body 10 extends along a first transverse direction; the first lifting shaft is arranged in the middle of the beam body 10 and extends along a second transverse direction, and there is an included angle between the first transverse direction and the second transverse direction; the two lifting lugs 30 are both arranged on the beam body 10 and extend along the vertical direction, and the two lifting lugs 30 are respectively located on both sides of the first lifting shaft; the two second lifting shafts 40 are both arranged on the beam body 10 and extend along the second transverse direction, and the two second lifting shafts 40 are respectively located on both sides of the first lifting shaft.

[0029] Applying the technical solution of the utility model, the lifting beam for the railway crane includes a beam body 10, a first lifting shaft, two lifting lugs 30 and two second lifting shafts 40. When used in cooperation with the railway crane, the hook of the railway crane is matched with the first lifting shaft of the lifting beam, and the two lifting lugs 30 of the lifting beam are used to hang heavy objects. When used for loading and unloading ships at the port, ropes are respectively hung on the two hook bodies of the hook of the ship's hull, and the other ends of the ropes are respectively sleeved on the two second lifting shafts 40 of the lifting beam, and the two lifting lugs 30 of the lifting beam are used to hang the crane, so that the crane can be lifted and transferred between the ship and the ground. By arranging the additional two second lifting shafts 40, the loading and unloading of the crane on the ship is realized. Moreover, since the two second lifting shafts 40 are respectively located on both sides of the first lifting shaft, the distance between the second lifting shafts 40 is increased, forming a stable support structure, with higher safety, and there is no need to increase the volume of the beam body 10.

[0030] Wherein, there are two first lifting shafts, and the two first lifting shafts are respectively used in cooperation with the two hook bodies of the hook of the crane.

[0031] Specifically, a lifting hole is arranged on the underframe of the railway crane, and a lifting shaft is inserted into the lifting hole and used in cooperation with the rope.

[0032] Of course, if the self-lifting capacity of the hook of the ship's hull is insufficient, other ship cranes with large tonnage can be used for loading and unloading operations on the ship.

[0033] In this embodiment, the two lifting lugs 30 are hinged to the beam body 10.

[0034] Wherein, the first lifting shaft and the second lifting shafts 40 are replaceable lifting shafts, corresponding to different working conditions. When used in cooperation with the railway crane, the hook of the railway crane is matched with the first lifting shaft of the lifting beam. When used for loading and unloading ships at the port, the rope is matched with the second lifting shafts 40. Of course, two first lifting shafts and two second lifting shafts 40 can also be respectively arranged.

[0035] Such as Figure 1As shown, the second suspension shaft 40 is located between the first suspension shaft and the corresponding lifting lug 30. With the above arrangement, the existing space of the beam body 10 can be fully utilized for the arrangement of the second suspension shaft 40, without major changes to the structure of the beam body 10.

[0036] As Figure 3 and Figure 5 shown, the beam body 10 includes an upper cover plate 15, a lower cover plate 16, and side plates disposed between the upper cover plate 15 and the lower cover plate 16. The upper cover plate 15, the lower cover plate 16, and the side plates enclose a hollow cavity. A transverse perforation 11 communicating with the hollow cavity is provided on the upper cover plate 15, and a sling avoidance hole 12 communicating with the hollow cavity and penetrating through is provided on the side plate. The transverse perforation 11 extends along the second transverse direction, and the second suspension shaft 40 is inserted through the transverse perforation 11. With the above structure, first pass the rope through the sling avoidance hole 12 into the beam body 10, and then insert the second suspension shaft 40, then the rope can be put on the second suspension shaft 40, which has the advantages of simple structure and convenient operation.

[0037] In this embodiment, the first transverse direction and the second transverse direction are perpendicular.

[0038] As Figure 3 and Figure 4 shown, a guide plate 13 is provided on the inner wall of the side plate. The guide plate 13 is located between the sling avoidance hole 12 and the transverse perforation 11. The side wall of the guide plate 13 is flush with the hole wall of the sling avoidance hole 12, or the side wall of the guide plate 13 is higher than the hole wall of the sling avoidance hole 12. The guide plate 13 can be used to guide the rope, avoiding friction between the rope and the hole wall of the sling avoidance hole 12 and damaging the rope, thereby protecting the rope.

[0039] In this embodiment, the outer wall of the guide plate 13 has a smooth transition.

[0040] As Figure 3 shown, the guide plate 13 is an L-shaped plate. The vertical plate section of the L-shaped plate is connected to the top wall of the beam body 10, and the horizontal plate section of the L-shaped plate is connected to the side wall of the beam body 10. With the structure of the L-shaped plate, it is convenient for the guide plate 13 to be connected to the top wall and the side wall of the beam body 10 and guide the rope.

[0041] Among them, L-shaped plates are provided on both side walls of the beam body 10.

[0042] As Figure 3 shown, a reinforcing plate 14 is further provided on the inner wall of the side plate. The reinforcing plate 14 is located below the guide plate 13, and a through hole is provided on the reinforcing plate 14. The through hole is coaxially arranged with the transverse perforation 11. The reinforcing plate 14 can be used to increase the structural strength of the beam body 10 at the location of the transverse perforation 11. After the second suspension shaft 40 is inserted and stressed, the structure of the beam body 10 is more stable.

[0043] In this embodiment, reinforcing plates 14 are provided on both side walls of the beam body 10.

[0044] Among them, the structure at the first suspension shaft of the beam body 10 is the same as that at the second suspension shaft 40. A transverse perforation and a hook body avoidance hole are also provided at the first suspension shaft. A protective plate and a strengthening plate are provided on the inner wall of the beam body 10. The side wall of the protective plate is flush with or slightly higher than the hole wall of the hook body avoidance hole. The through hole on the strengthening plate is coaxially arranged with the transverse perforation.

[0045] As Figure 5 shown, the side plate includes two sealing plates 17 and two web plates 18. The two sealing plates 17 are respectively located at both ends of the upper cover plate 15. Both ends of the sealing plate 17 are connected to the upper cover plate 15 and the lower cover plate 16 respectively. The two web plates 18 are respectively located on both sides of the upper cover plate 15. The outer wall of the web plate 18 is connected to the upper cover plate 15, the lower cover plate 16 and the two sealing plates 17. The transverse perforation 11 penetrates through the two web plates 18. The beam body 10 with the above structure has the advantages of simple structure and convenient processing.

[0046] In this embodiment, the guide plate 13 and the reinforcing plate 14 are respectively arranged on the inner side walls of the two web plates 18.

[0047] Among them, a connecting partition is also provided between the two web plates 18 to enhance the connection strength between the two web plates.

[0048] As Figure 4 shown, the second suspension shaft 40 includes a shaft body 41 and an end plate 42 provided at the end of the shaft body 41. The shaft body 41 is located in the transverse perforation 11, and the end plate 42 is attached to the outer side wall of the beam body 10. The end plate 42 can be used to cooperate with the outer side wall of the beam body 10 to limit the shaft body 41 and prevent the second suspension shaft 40 from moving in the transverse perforation 11.

[0049] Among them, a handle 43 is provided on the second suspension shaft 40. The handle 43 is convenient for the operator to pick up and place.

[0050] In this embodiment, a detachable chain 44 is provided between the second suspension shaft 40 and the beam body 10. The chain 44 can be used to connect the second suspension shaft 40 to the beam body 10 to prevent the second suspension shaft 40 from detaching from the beam body 10 and injuring people.

[0051] As Figure 4 shown, a baffle 19 is provided on the outer side wall of the beam body 10. There is an avoidance groove between the side wall of the baffle 19 and the outer side wall of the beam body 10. The end plate 42 is located between the outer side wall of the beam body 10 and the baffle 19. An avoidance notch for avoiding the baffle 19 is provided on the end plate 42. The baffle 19 can be used to block the end plate 42, thereby preventing the second suspension shaft 40 from falling off from the transverse perforation 11.

[0052] Specifically, when the second suspension shaft 40 is inserted into the transverse perforation 11, align the avoidance notch with the baffle 19 so that the end plate 42 can cross over the baffle 19. After the second suspension shaft 40 is assembled, rotate the second suspension shaft 40, and then the baffle 19 can limit the end plate 42.

[0053] Another embodiment of the present application provides a railway crane, which includes a crane body and a suspension beam. The crane body has a hook, and the first suspension shaft of the suspension beam can cooperate with the hook, and the suspension beam is the suspension beam provided above. When used in cooperation with the railway crane, the hook of the railway crane is made to cooperate with the first suspension shaft of the suspension beam, and a heavy object is suspended by the two suspension lugs 30 of the suspension beam. When used for ship loading and unloading in a port, ropes are respectively suspended on the two hook bodies of the hook of the hull, and the other ends of the ropes are respectively sleeved on the two second suspension shafts 40 of the suspension beam. By using the two suspension lugs 30 of the suspension beam to suspend the crane, the crane can be lifted and transferred between the ship and the ground. By providing two additional second suspension shafts 40, the ship loading and unloading of the crane is realized. Moreover, since the two second suspension shafts 40 are respectively located on both sides of the first suspension shaft, the distance between the second suspension shafts 40 is increased, forming a stable support structure, with higher safety and no need to increase the volume of the beam body 10.
