Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a crane hook assembly, including a housing 1, a first bolt 2 penetrates through the surface of the housing 1, a roller 3 is connected inside the housing 1, a first rotating shaft 4 is fixedly connected to the surface of the roller 3, a first fixing piece 5 is fixedly connected to the surface of the first rotating shaft 4, a connecting component 6 is connected inside the housing 1, a second rotating shaft 7 is fixedly connected to the surface of the connecting component 6, a second fixing piece 8 is fixedly connected to the surface of the second rotating shaft 7, a rotating groove 9 is opened inside the connecting component 6, a rotating block 10 is connected inside the rotating groove 9, a hook 11 is fixedly connected to the surface of the rotating block 10, a baffle component 12 is fixedly connected to the surface of the hook 11, and a lubricating mechanism 13 is arranged on the surface of the housing 1.
[0020] Furthermore, there are two groups of the first bolts 2 arranged on the surface of the housing 1, and the two groups of the first bolts 2 are symmetrically arranged about the first fixing piece 5 on the surface of the housing 1. Through the arrangement of the first bolts 2, when in use, the first bolts 2 will fix the housing 1, thereby making the fixation more stable.
[0021] Furthermore, the roller 3 is located at the central position inside the housing 1, and the roller 3 is rotationally connected to the housing 1 through the first rotating shaft 4. Through the arrangement of the roller 3, when the hook assembly needs to be used, first wind the wire on the surface of the roller 3, and then when the equipment operates, the hook assembly will rise and fall by driving the rotation of the roller 3 through the wire.
[0022] Furthermore, the connecting component 6 is rotationally connected to the housing 1 through the second rotating shaft 7, and the connecting component 6 and the housing 1 are rotationally connected. Through the arrangement of the connecting component 6, when in use, the hook 11 can be adjusted through the connecting component 6 and the second rotating shaft 7.
[0023] Furthermore, the size of the rotating groove 9 matches the size of the rotating block 10, and the hook 11 is rotationally connected to the connecting component 6 through the rotating block 10. Through the arrangement of the rotating groove 9 and the rotating block 10, when in use, the rotating groove 9 will limit the rotating block 10, and at the same time enable the hook 11 to rotate through the rotating block 10.
[0024] Furthermore, the lubrication mechanism 13 includes a fixing plate 1301, a second bolt 1302, an oil storage box 1303, an oil injection port 1304, a rotating shaft 1305, and a ball 1306. A fixing plate 1301 is fixedly connected to the surface of the housing 1. A second bolt 1302 penetrates through the surface of the fixing plate 1301. An oil storage box 1303 is fixedly connected to the surface of the fixing plate 1301. An oil injection port 1304 is formed in the surface of the oil storage box 1303. A rotating shaft 1305 is rotatably connected to the inside of the oil storage box 1303. A ball 1306 is fixedly connected to the surface of the rotating shaft 1305. Through the arrangement of the lubrication mechanism 13, during the operation of the device, first, lubricating oil is injected into the oil storage box 1303 through the oil injection port 1304. Subsequently, when the wire slides on the surface of the roller 3, the sliding wire drives the ball 1306 to rotate. When the ball 1306 rotates, it takes out the lubricating oil in the oil storage box 1303 to the surface of the wire, thereby lubricating the wire and avoiding the wire from breaking due to dryness.
[0025] Furthermore, there are two groups of fixing plates 1301, and the two groups of fixing plates 1301 are symmetrically arranged with the oil storage box 1303 as the center. Through the arrangement of the fixing plate 1301, during use, the oil storage box 1303 is fixed to the surface of the housing 1 through the fixing plate 1301, making the fixation of the oil storage box 1303 more stable.
[0026] Working principle: During use, the first bolt 2 fixes the housing 1, making the fixation more stable. When the hook assembly needs to be used, first, the wire is wound around the surface of the roller 3. Subsequently, when the device operates, the hook assembly drives the roller 3 to rotate through the wire for ascending and descending. Additionally, the rotating groove 9 limits the rotating block 10, and at the same time enables the hook 11 to rotate through the rotating block 10. During the operation of the device, first, lubricating oil is injected into the oil storage box 1303 through the oil injection port 1304. Subsequently, when the wire slides on the surface of the roller 3, the sliding wire drives the ball 1306 to rotate. When the ball 1306 rotates, it takes out the lubricating oil in the oil storage box 1303 to the surface of the wire, thereby lubricating the wire and avoiding the wire from breaking due to dryness.
[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
