[0027] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the application, and not to limit the application. In addition, it should be noted that, for the sake of description, only parts related to the application are shown in the drawings.
[0028] As Figure 1 and Figure 2 shown, the embodiment of the application provides a hoisting beam 10, comprising:
[0029] The hoisting beam body 11 is of a flat plate structure,
[0030] The hoisting beam body 11 is provided with a plurality of groups of first through holes 13 and a plurality of groups of second through holes 14. The first through holes 13 are arranged at the upper end of the hoisting beam body 11 and are used to be connected to a hook. The second through holes 14 are arranged at the lower end of the hoisting beam body 11 and are used to be connected to a hoisted object.
[0031] The embodiment provides a hoisting beam 10 as an intermediate load-bearing beam during hoisting use of a floating crane 20. The hoisting beam is of a flat plate structure, simple in structure and requiring less material, capable of meeting the hoisting requirement while reducing material and cost, and capable of forming hoisting beams with different load-bearing capacities according to different hoisted product weights to adapt to different hoisting scenarios, capable of using corresponding hoisting beams in different scenarios and with different load-bearing capacities, and capable of saving production cost.
[0032] Each group of first through holes 13 is provided with a first amplitude limiting rod assembly above. Each group of second through holes 14 is provided with a second amplitude limiting rod assembly below. The first amplitude limiting rod assembly can limit the amplitude of a rope hoisted in the first through hole 13 to limit the swing amplitude of the rope relative to the hoisting beam when the hoisting beam swings in the air, reducing the wear between the rope and the hoisting beam. The second amplitude limiting rod assembly can limit the amplitude of a rope hoisted in the second through hole 14 to limit the swing amplitude of the rope relative to the hoisting beam when the hoisted object swings in the air, reducing the wear between the rope and the hoisting beam. The first amplitude limiting rod assembly and the second amplitude limiting rod assembly can be located on the same side of the hoisting beam body 11 along the thickness direction thereof or on opposite sides of the hoisting beam body 11 along the thickness direction thereof.
[0033] Figure 2 The side structure schematic diagram of the hoisting beam 10 provided by the embodiment is shown in Figure 2It can be known that the hoisting beam provided in the embodiment is a flat plate structure, which is a plate with a certain thickness, and the hoisting hole position is reinforced by the webs 12 on both sides. The hoisting beam with the plate structure is simple in structure, and the plate thickness and size are selected according to different floating crane 20 devices and different bearing capacity requirements to form hoisting beams with different bearing capacities. The hoisting beam in the embodiment adopts a flat plate structure, and the preparation process is also simple, without complex process, and the process is low in process and cost. A plurality of different through holes are arranged on the hoisting beam, a first through hole 13 is arranged at the upper end, and a second through hole 14 is arranged at the lower end. The first through hole 13 is connected with the lifting hook on the floating crane 20, and the second through hole 14 is connected with the product to be hoisted, forming a structure as shown in Figure 3 The hoisting beam is used for hoisting the product to be hoisted, and the first through hole 13 and the second through hole 14 are arranged in the form of two groups each. One group of first through holes 13 and one group of second through holes 14 are used together, and each group of through holes is connected to one lifting hook, so that the hoisting is more stable.
[0034] Optionally, the hoisting beam further comprises:
[0035] A plurality of webs 12 are arranged on the hoisting beam, and each group of webs 12 comprises two webs 12 arranged oppositely. Each group of webs 12 is arranged correspondingly to one group of through holes and is fixed to the two sides of the hoisting beam body 11.
[0036] As shown in Figure 1 The webs 12 are arranged on the two sides of the hoisting beam body 11, and the number of the webs 12 is related to the number of the groups of through holes. That is, the corresponding webs 12 are arranged on the two sides of each group of through holes. The strength of the through hole position is increased by the webs 12, so that the hoisting beam is more durable and the through hole position is not prone to damage. The webs 12 in the embodiment are preferably arranged in a waist-shaped structure. The webs 12 are provided with through holes matched with the through holes on the hoisting beam body 11. The two ends of the waist-shaped web 12 are semicircular structures, and the diameters of the semicircles at the two ends of the web 12 are twice the diameters of the corresponding through hole positions. The size setting can ensure the increase of the strength of the hoisting beam body 11 by the web 12, and also can use less size of web 12 material, which ensures the strength while saving materials.
[0037] Optionally, the hoisting beam body 11 is provided with two groups of first through holes 13, and the two groups of first through holes 13 are arranged at the same height of the hoisting beam.
[0038] The hoisting beam body 11 is provided with two groups of second through holes 14, and the two groups of second through holes 14 are arranged at the same height of the hoisting beam.
[0039] As shown in Figure 1As shown, the hoisting beam provided in the embodiment is provided with two groups of first through holes 13 arranged side by side and two groups of second through holes 14 arranged side by side, wherein the spacing between the two groups of first through holes 13 is greater than the spacing between the two groups of second through holes 14, and the spacing between each group of first through holes 13 is related to the spacing of the hooks 21 of the floating crane 20, such as Figure 3 As shown, in use of the hoisting beam in the embodiment, there are two hooks on each hook 21 of the floating crane 20, and the two hooks are used simultaneously for hoisting. The embodiment sets the spacing between each group of first through holes 13 to be the same as the spacing between the two hooks, so that the ropes between the floating crane 20 and the hoisting beam are in a vertical form when the hoisting beam is in use, without inclination, which does not affect the use and strength. The spacing between each group of second through holes 14 is selected and adjusted according to actual needs. The first and second limiting rod assemblies are arranged staggered with the web plate 12, and the first and second limiting rod assemblies protrude from the web plate 12. The first limiting rod assembly includes two first limiting rods arranged at intervals, and the two first limiting rods are respectively located on both sides of the center line between the two first through holes 13 and the spacing between the two first limiting rods is less than the spacing between the two first through holes 13. The two second limiting rods are respectively located on both sides of the center line between the two second through holes 14, and the spacing between the two second limiting rods is less than the spacing between the two second through holes 14. The first limiting rod and the second limiting rod are screwed with the hoisting beam body 11 to facilitate disassembly and subsequent replacement.
[0040] Optionally, the end of the hoisting beam body 11 close to the second through hole 14 is provided with a cut corner 15.
[0041] As Figure 1 As shown, the hoisting beam body 11 is in the form of a plate, preferably made of a rectangular plate, which has a regular structure and is convenient to cut. The strength of the hoisting beam is met while the weight of the hoisting beam is reduced as much as possible to reduce weight and save resources. Preferably, the angle of the hoisting beam body 11 is removed to form a cut corner 15 to reduce weight. The arrangement of the cut corner 15 cannot affect the arrangement of the through hole and cannot affect the use of the through hole position, and cannot affect the strength of the through hole position during hoisting.
[0042] Optionally, the thickness of the web plate 12 is less than or equal to half the thickness of the hoisting beam body 11.
[0043] The embodiment increases the strength of the hoisting beam body 11 by attaching a web plate 12 at each group of through hole positions, as shown in Figure 1 and Figure 2As shown in the drawings, the web plate 12 is only attached to the position of the through hole to partially reinforce, and the thickness of the web plate 12 is moderate. If the thickness of the web plate 12 is too thin, the reinforcing effect on the through hole position of the hoisting beam is insufficient, which affects the use of the hoisting beam. If the thickness of the web plate 12 is too thick, resources will be wasted. In the embodiment, the thickness of the web plate 12 is preferably set to be within half of the thickness of the hoisting beam body 11. For example, if the thickness of the hoisting beam body 11 is 48 mm, the thickness of the web plate 12 can be selected to be 20 mm or 22 mm.
[0044] Optionally, the spacing between each group of first through holes 13 is matched with the spacing between the hooks on each lifting hook 21.
[0045] Reference Figure 3 As shown in the drawings, in the embodiment, when the hoisting beam is used, the upper first through hole 13 is connected with the lifting hook 21 on the floating crane 20. In order to make the hoisting cable straight during hoisting, the use is safer. The spacing between the two groups of first through holes 13 arranged at the upper end is related to the span between the two lifting hooks 21 on the floating crane 20, which can be replaced according to the type of the floating crane 20 to be used.
[0046] Optionally, the strength of the hoisting beam steel is at least greater than Q345-B. The hoisting beam in the embodiment is generally applied to a large floating crane 20 device, which requires a large carrying capacity. For example, the hoisting beam in the embodiment is made of Q345-B steel, which has a carrying capacity of at least 520 tons to meet the use requirements.
[0047] The embodiment also provides a hoisting tool, which comprises the hoisting beam;
[0048] The hoisting tool is provided with at least two lifting hooks 21, and the hoisting beam cooperates with the lifting hooks 21.
[0049] The embodiment also provides a hoisting tool, which comprises the hoisting beam; Figure 3 As shown in the drawings, the hoisting beam disclosed in the above embodiment is applied to the hoisting tool. The hoisting tool is a floating crane 20 device. The floating crane 20 device is generally provided with four lifting hooks 21. Two lifting hooks 21 cooperate with each other and cooperate with a hoisting beam to form Figure 3 As shown in the drawings, the hoisting beam is used for hoisting the object to be hoisted below the hoisting beam. The hoisting beam is a flat plate structure, which is simple in structure and requires less material. The hoisting beam can meet the hoisting requirements while reducing materials and costs. The hoisting beam can form hoisting beams with different carrying capacities according to the weight of the hoisted product, so as to adapt to different hoisting scenes. The corresponding hoisting beam can be used in different scenes and with different carrying capacities, thereby saving production costs.
