Technical Field

[0001] The utility model relates to the technical field of gantry cranes, in particular to a hook structure of a gantry crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. Among them, a gantry crane (also known as a bridge crane) is a bridge-type crane whose bridge is supported on the ground track by legs on both sides. During production operations such as galvanizing, lifting is required through the hook structure of the gantry crane.

[0003] At present, when using crane hooks, there is a lack of double hook safety mechanism. Usually, a single hook structure is used during the operation of the hook. However, due to long-term use, the hook is easily damaged due to the influence of use quality and environmental factors, which poses a safety hazard. In addition, the stability during movement is relatively general. Therefore, a gantry crane hook structure is proposed, so that in the actual work process, through the double hook mechanism, the working stability is improved, the safety of use is increased, and it is less susceptible to damage caused by environmental factors to affect the use effect, thereby improving the use effect.

[0010] Specifically, the top of the hook body is connected to a mounting seat by welding, and the hook body is rotatably connected to the mounting assembly by a rotating shaft, and a positioning hole is opened on the surface of the mounting seat.

[0011] By adopting the above technical solution, the hook body assembly can be installed for use.

[0012] Specifically, an arc spring is installed on the other side of the sliding block in the slideway through a slot.

[0018] Specifically, an air nozzle corresponding to the arc-shaped air cushion strip is provided on the outer surface of the hook body.

[0019] By adopting the above technical solution, it is convenient to inflate and deflate the arc-shaped air cushion strip through an external air pump.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to improve the stability of work and increase the safety of use, it is less susceptible to damage caused by environmental factors and affect the use effect, thereby improving the use effect, such as Figure 1-3 As shown, a gantry crane hook structure described in the utility model comprises a connecting component 1, a mounting component 2 and a hook component 3, wherein the bottom of the connecting component 1 is provided with the mounting component 2, and opposite hook components 3 are provided on both sides of the bottom of the mounting component 2;

[0031] The hook assembly 3 includes a hook body 301, and the top of the hook body 301 is rotatably connected to the mounting assembly 2. The outer surface of the hook body 301 is connected to an electromagnet 302 by bolts. A slideway 303 is provided on the inner side of the hook body 301, and the top of the slideway 303 is slidably connected to a limiting block 304.

[0032] When in use, the magnetic attraction generated by the electromagnet 302 can quickly assist the hook fixing action and form a double hook structure, thereby improving the stability and safety of the gantry crane.

[0033] In order to improve the stability of the hook working material, exemplary, such as Figure 2 , Figure 3 As shown, the utility model also includes that the limit block 304 includes a slider 305, and the limit block 304 is slidably connected to the slideway 303 through the bottom slider 305, and an arc-shaped air cushion strip 306 is glued to one side of the slider 305 in the slideway 303.

[0034] When in use, the deformation caused by the inflation of the arc-shaped air cushion strip 306 can be used to push the limit block 304 to move to perform an auxiliary limit action, while reducing the impact caused by the shaking of the material, thereby improving the stability of the material.

[0035] For example, Figure 2 As shown, the utility model also includes that the top of the hook body 301 is connected to a mounting seat 308 by welding, and the hook body 301 is rotatably connected to the mounting assembly 2 through a rotating shaft, and a positioning hole 309 is opened on the surface of the mounting seat 308.

[0036] When in use, the mounting seat 308 and the positioning hole 309 facilitate rotation and connection of the mounting assembly 2 .

[0037] For example, Figure 3 As shown, the utility model further includes that an arc spring 307 is installed on the other side of the slide block 305 in the slideway 303 through a slot.

[0038] When in use, the elastic force of the arc spring 307 facilitates the slider 305 to perform a reset sliding action.

[0039] For example, Figure 1 As shown, the utility model also includes that the connection assembly 1 includes a connection plate 101 , the top of the connection plate 101 is connected to a connection ring 102 by welding, and a through hole 103 is opened on the surface of the connection plate 101 .

[0040] When in use, the connecting plate 101, the connecting ring 102 and the through hole 103 facilitate the fixing and connection of connecting components such as the pulley block of the gantry crane.

[0041] For example, Figure 4As shown, the utility model also includes that the mounting assembly 2 includes a mounting frame 201, the surface and back of the mounting frame 201 are connected to the servo motor 203 by bolts, and the servo motor 203 is connected to the hook assembly 3 through a driving shaft, the surface and back of the mounting frame 201 are located at the bottom of the servo motor 203 and are threadedly connected with a positioning screw 202 through a reserved threaded hole, and the top of the mounting frame 201 is connected to the fixing seat 204 by welding.

[0042] When in use, the servo motor 203 drives the hook assembly 3 to rotate back and forth, and can perform automatic unhooking and hooking actions, thereby improving the convenience and flexibility of use. The positioning screw 202 is convenient for manual limit fixing of the hook body 301.

[0043] For example, Figure 2 As shown, the utility model also includes that the outer surface of the hook body 301 is provided with an air nozzle 310 corresponding to the arc-shaped air cushion strip 306 .

[0044] When in use, the air nozzle 310 is conveniently connected to an external air pump to inflate and deflate the arc-shaped air cushion strip 306 .

[0045] When the utility model is used, the operator first fixes the steel wire rope connected to the gantry crane pulley block and other components through the connecting ring 102. During use, the gantry crane is used to move the hook to the top of the material, and the servo motor 203 is manually turned on to drive the hook bodies 301 of the two sets of hook assemblies 3 to rotate relative to each other, thereby forming a clamping double hook structure, and the electromagnet 302 is manually turned on at the same time, and the magnetic force generated by the electromagnet 302 is attracted to tighten the hook bodies 301 to complete the magnetic attraction fixing process;

[0046] The external air pump can also be turned on manually. The air pump inflates the arc-shaped air cushion strip 306 by connecting the air nozzle 310, and uses the deformation caused by the inflation to push the slider 305 and the limit block 304 to move and slide, so that they slide to the two sides of the material pull rope for auxiliary limiting processing. Then, the positioning screw 202 is manually inserted and tightened to limit and fix the mounting seat 308. This can not only improve the safety and stability of the use of the hook, but also use the arc-shaped air cushion strip 306 to slow down the shaking of the material during the movement, thereby further improving the stability and safety of the hook.
