Description
Technical Field
[0001] The invention belongs to the technical field of suspension equipment, and in particular relates to a suspension equipment of a port crane. Background Art
[0002] When transporting goods at ports, gantry cranes are needed. Gantry cranes are a variation of bridge cranes. Gantry cranes are a common type of lifting equipment. When a gantry crane is working, the staff will use the crane's hook to lift the goods. Two legs are installed under the main beam, which can walk directly on the ground track. Gantry cranes have the characteristics of site utilization, large operating range, and wide adaptability. At present, the suspension equipment of gantry cranes on the market usually consists of an electric hoist and a hook. The electric hoist can drive the hook up and down through the wire rope, and can complete the lifting of the goods by the hook. This kind of suspension equipment can indeed achieve a good lifting effect on the goods in actual use. However, there is no good hook fixing structure on the suspension equipment. When the crane is not working, the electric hoist needs to store the wire rope. At this time, the distance between the hook and the electric hoist will also be reduced. When the staff starts the crane's support leg to reset, the hook is prone to swing. If the swing amplitude of the hook is large, it is easy to cause a collision between the hook and the electric hoist, which in turn causes the electric hoist to be easily damaged by collision.

DETAILED DESCRIPTION
[0014] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] like Figure 1-Figure 6 The suspension device of a port crane shown in the figure comprises a gantry frame body 2 and a driving structure 1 detachably connected to the gantry frame body 2, a mounting frame 3 is detachably connected to the lower part of the driving structure 1, a connecting cable 26 is passed through the mounting frame 3, the lower end of the connecting cable 26 is connected to a hook 8 through a connecting member 25, the bottom surface of the mounting frame 3 is located on one side of the connecting cable 26 and is fixedly connected to a fixing plate 9 through a fixing bolt 28, the bottom surface of the fixing plate 9 is fixedly connected to a connecting pipe 10, the lower end of the connecting pipe 10 is fixedly connected to a plug-in pipe 6, and the upper part of the plug-in pipe 6 is provided with a mounting plate 9. The mounting cavity 18 is provided, and an electromagnet 17 is embedded in the middle of the inner cavity of the mounting cavity 18. A through plate 12 is penetrated at equal intervals on the mounting cavity 18. A magnetic plate 16 is fixedly connected to one end of the through plate 12 close to the electromagnet 17. A connecting spring 15 is fixedly connected between the magnetic plate 16 and the mounting cavity 18. A sleeve ring 20 is sleeved on the plug-in tube 6. A transverse rod 21 is fixedly connected to the sleeve ring 20. A transverse plate 22 is fixedly connected to one end of the transverse rod 21 away from the sleeve ring 20. The transverse plate 22 is fixedly connected to the connecting member 25 by means of a mounting bolt 27. When the transverse plate 22 is fixedly connected to the connecting member 25 by installing bolts 27, the plug-in tube 6 can penetrate the sleeve ring 20, so that the plug-in tube 6 can limit the support of the connecting member 25 to prevent the connecting member 25 from swinging when the gantry frame 2 moves.
[0016] An abutment sheet 11 is sleeved between the connecting tube 10 and the plug-in tube 6, and a sleeve ring 20 is distributed between the penetration plate 12 and the abutment sheet 11, and the magnetic poles of the magnetic attraction plate 16 and the magnetic poles of the electromagnet 17 repel each other; When the plug-in tube 6 and the sleeve ring 20 are inserted, the staff starts the electromagnet 17 inside the installation cavity 18. Since the magnetic poles of the electromagnet 17 and the magnetic poles of the magnetic attraction plate 16 repel each other, the electromagnet 17 can drive the penetration plate 12 to extend out from the inside of the installation cavity 18 through the magnetic attraction plate 16. At this time, the sleeve ring 20 can be distributed between the penetration plate 12 and the abutment plate 11.
[0017] The top surface of the electromagnet 17 is fixedly connected with a mounting seat 14, and the mounting seat 14 is fixedly connected to the inner wall of the mounting cavity 18 through a fixing frame 32. The electromagnet 17 is connected with a connecting wire 13, and the connecting wire 13 passes through the abutting piece 11 and the connecting tube 10; The electromagnet 17 may be a structure currently available on the market. The mounting seat 14 on the electromagnet 17 may be firmly connected to the inside of the mounting cavity 18 via a fixing frame 32 , so that the electromagnet 17 can stably work inside the mounting cavity 18 .
[0018] The bottom surface of the horizontal plate 22 is fixedly connected with a vertical plate 24, and an inclined support rod 23 is fixedly connected between the vertical plate 24 and the horizontal rod 21. The vertical plate 24 is also fixedly connected with the connecting member 25 by means of mounting bolts 27; The vertical plate 24 can cooperate with the horizontal plate 22 to firmly connect the sleeve ring 20 to the connecting piece 25 , and the plug-in tube 6 can penetrate the sleeve ring 20 , so that the plug-in tube 6 can provide limited support to the connecting piece 25 .
[0019] The upper collar 7 and the lower sleeve 19 are fixedly connected to the side of the vertical plate 24 away from the inclined support rod 23. The upper collar 7 and the lower sleeve 19 can be sleeved on the connecting member 25. The bottom surface of the lower sleeve 19 is fixedly connected to the side away from the vertical plate 24 with an inclined stop bar 31. When the upper sleeve ring 7 and the lower sleeve 19 are sleeved on the connecting piece 25, the vertical plate 24 can cooperate with the horizontal plate 22 to firmly connect the sleeve ring 20 to the connecting piece 25, so as to prevent the sleeve ring 20 from being easily separated from the connecting piece 25. When in use, the inclined baffle 31 can block one side of the hook 8, so as to prevent the hook 8 from swinging significantly when the hook 8 is lifting the goods.
[0020] A fixing bar 29 is fixedly connected to the top surface of the mounting frame 3 in the middle, and the upper end of the fixing bar 29 is fixedly connected to the driving structure 1. An electric hoist 5 is detachably connected to the top surface of the mounting frame 3, and the output end of the electric hoist 5 is connected to the upper end of the connecting rope 26. The electric hoist 5 can be selected from existing structures on the market. The electric hoist 5 can drive the hook 8 to move up and down through the connecting rope 26, so that the hook 8 can drive the goods to move up and down.
[0021] A through hole 30 is detachably connected to one side of the mounting frame 3 near the connecting pipe 10, and the upper end of the connecting wire 13 passes through the through hole 30 and the mounting frame 3, and a transport structure 4 is distributed below the mounting frame 3; The hook 8 can drive the goods to be transported to the transport structure 4 , and the upper end of the connecting wire 13 can pass through the mounting frame 3 to be connected to an external power source, so that the electromagnet 17 can work stably inside the mounting cavity 18 .
[0022] Working principle: When the equipment is actually used, the staff starts the electric hoist 5 to work. The electric hoist 5 can drive the hook 8 to move up and down through the connecting rope 26. At this time, the hook 8 can lift the goods to the transport structure 4. When the hook 8 has completed lifting the goods, the electric hoist 5 can retract the connecting rope 26. At this time, the distance between the hook 8 and the electric hoist 5 can be reduced. At the same time, the connecting piece 25 can drive the sleeve ring 20 to be sleeved on the plug-in tube 6. Then the staff starts the electromagnet 17 to work. Since the magnetic poles of the electromagnet 17 and the magnetic poles of the magnetic suction plate 16 repel each other, the electromagnet 17 can drive the through plate 12 to extend from the inside of the installation cavity 18 through the magnetic suction plate 16. At this time, the sleeve ring 20 can be distributed between the through plate 12 and the abutment plate 11, which can prevent the hook 8 from colliding with the electric hoist 5 when the gantry body 2 moves.
