[0001] The present invention relates to a transfer crane, in particular to a special transfer crane for automobile parts applied in the technical field of lifting equipment. Background Art

[0002] Automobile products are assembled from a variety of parts, and each part of an automobile product is manufactured in a different factory. During the assembly and transportation process, the parts will be transferred short distances within the workshop, and most of them are directly transferred using lifting equipment such as cranes and overhead cranes.

[0003] The specification of Chinese invention patent CN202222456047.1 discloses "A lifting device for transporting and lifting batteries of electric vehicles". In order to solve the problem that when the lifting device moves, the personnel who push the device to move have limited field of vision, find it difficult to effectively avoid obstacles, and are inconvenient to move, this patent sets an ultra-wide-angle camera on the top of the gantry, and a display is set on the side wall of the gantry and opposite to the wide-angle camera. The display is electrically connected to the wide-angle camera, and early warning protection of lifting and transportation is performed through video monitoring.

[0004] Due to the variety of types of auto parts, in order to better transport auto parts, the workshop currently provides special loading racks according to the shape of the parts. However, different racks use different sling binding techniques, which makes the preparation work for lifting and transporting parts complicated, affecting the efficiency of lifting and transporting. In addition, during the transportation process, the use of video monitoring is prone to monitoring blind spots, and the monitoring judgment relies on manual labor, making lifting and transport operations difficult, affecting the transportation efficiency of auto parts. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the preparation work for the lifting and transportation of parts is complicated, and during the transportation process, the use of video monitoring is prone to monitoring blind spots, and the monitoring and judgment rely on manual labor, making the lifting and transportation operations difficult, affecting the transportation efficiency of automobile parts.

[0008] In the above-mentioned special transfer crane for automobile parts, the hook on the lifting assembly is hooked onto the frame column on the frame column to realize the rapid lifting of the material rack, and it can adapt to any size of material rack with a frame column. Subsequently, the buffer pad bag on the lifting assembly is used to provide edge buffer protection for the automobile parts.

The horizontal position of the positioning frame can be quickly adjusted by utilizing the combined extension and retraction of the hydraulic cylinders.

[0015] As another improvement of the present application, the inside of the rope hole is rotatably connected with an axle ring, one end of the inner wall of the axle ring is rotatably connected with a pulley, the sling corresponds to the pulley, and the axle ring cooperates with the pulley to effectively improve the movement effect of the sling in the rope hole, and effectively reduce the wear of the sling and the rope hole.

[0016] As another improvement supplement of the present application, a lubrication module is fixedly connected to the outside of the rope hole, and the oil delivery end of the lubrication module corresponds to the shaft ring. The shaft ring is made of wear-resistant metal material. The lubrication module provides lubricating oil to the shaft ring, effectively improving the rotation effect of the shaft ring.

[0017] As another improvement supplement of the present application, the other end of the inner wall of the collar is fixedly connected with an anti-slip bracket, the outer end of the anti-slip bracket is in active contact with the pulley, and the anti-slip bracket contacts the pulley to effectively prevent the sling on the pulley from detaching.

[0018] In summary, the present invention uses the hooks on the lifting components to hook the hook holes on the rack columns, so as to achieve rapid lifting preparation for the rack loaded with automobile parts, effectively improve the lifting and transportation efficiency of automobile parts, and adapt to racks of any size with rack columns, effectively improve the adaptability of the transfer crane, and facilitate the transportation and lifting operations of different types of automobile parts.

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-4 It is shown that a special transport crane for automobile parts includes a crane body 1 and a material rack 2. A moving lifting platform 101 is fixedly connected to the middle of the crane body 1. Both ends of the moving lifting platform 101 are movably connected to a sling 102. The bottom end of the sling 102 is fixedly connected to a hanging assembly 3. A frame column 201 is fixedly connected to the top periphery of the material rack 2. A hook hole 202 is opened on the outside of the frame column 201. A hook 301 is fixedly connected to one end of the hanging assembly 3 close to the frame column 201. The hook 301 is correspondingly engaged with the hook hole 202.

[0034] When lifting and transporting automobile parts, the corresponding rack 2 is selected according to the type of automobile parts. After the automobile parts are stably placed on the rack 2, the hook 301 on the lifting component 3 is hooked into the hook hole 202 on the rack column 201 to achieve rapid lifting preparation for the rack 2 loaded with automobile parts, effectively improving the lifting and transport efficiency of automobile parts, and adapting to any size of rack 2 with rack column 201, effectively improving the adaptability of the transfer crane, and facilitating the transfer and lifting operations of different types of automobile parts.

[0035] Figure 3-4 As shown, the hook 301 is arranged at a right angle, and the bottom of the bent end of the hook 301 is movably connected with a resisting pin 302, and the bottom of the hook hole 202 is fixedly connected with a gasket 303, and the bottom end of the resisting pin 302 contacts the gasket 303, and the extension of the resisting pin 302 restricts the hook 301 in the hook hole 202 to prevent the hook 301 from falling off, and the top of the resisting pin 302 is fixedly connected with an ejection spring 304, and the bottom of the resisting pin 302 is inclined at one end facing the hook hole 202, and the elastic force of the ejection spring 304 is used to realize the automatic extension of the resisting pin 302, and the resisting pin 302 with an inclined bottom is convenient for contraction in the process of the hook 301 being inserted into the hook hole 202;

[0036] When the hook 301 on the hanging assembly 3 is hooked on the hook hole 202 on the frame column 201, the hook 301 is first inserted into the hook hole 202, and the inclined surface at the bottom of the interference pin 302 interferes with the bottom of the hook hole 202, so that the interference pin 302 retracts into the hook 301. After the hook 301 completely enters the hook hole 202, the ejection spring 304 pushes the interference pin 302 out again, and the interference pin 302 interferes with the gasket 303 to realize the overall rise of the hook 301. The hook 301 is restricted above the hook hole 202, effectively preventing the hook 301 from falling off in a relaxed state.

[0037] Figure 1 and Figure 5-6As shown, a buffer pad bag 4 is fixedly connected to one end of the external part of the hanging component 3 away from the hanging hook 301, a buffer frame 401 is fixedly connected to the inside of the buffer pad bag 4, a buffer module 402 is fixedly connected between the back of the buffer frame 401 and the hanging component 3, the left and right ends of the buffer frame 401 both extend out of the buffer pad bag 4, and the left and right ends of the buffer frame 401 are fixedly connected to laser sensing belts 403, the top and bottom ends of the laser sensing belt 403 are both installed with laser emitters 404, the laser emitter 404 corresponds to the laser sensing belt 403, the output end of the laser sensing belt 403 is connected to an alarm module, and the buffer module 402 is set as a spring. The buffer skeleton 401 is made of aluminum alloy material, and the buffer pad package 4 is made of sponge material. The buffer skeleton 401 made of aluminum alloy material is light in weight and has high structural strength, which is convenient for operation and use of the lifting assembly 3. The buffer module 402 cooperates with the buffer pad package 4 to effectively improve the impact buffering capacity. The emission range of the laser emitter 404 is distributed in a fan shape. The two laser emitters 404 on the same laser sensor belt 403 share a switch module, and the switch module is set to a selection switch (the switch module is a selection switch of the prior art, that is, one of the two laser emitters 404 is turned on and the other is turned off). By selecting and controlling the opening and closing of the laser emitter 404, as shown in FIG. Figure 5 As shown, the same monitoring plane uses the least laser emitters 404, effectively reducing the energy consumption of laser monitoring;

[0038] During the lifting and shipping process of automobile parts, when an object passes through the laser sensing area between the laser emitter 404 and the laser sensing belt 403 and is about to collide with the automobile parts inside the rack 2, the laser is shielded by the object, triggering the monitoring of the laser sensing belt 403, and thus using the alarm module for early warning. When the object hits the buffer pad package 4 outside the lifting component 3, it means that the edge of the rack 2 has collided, and the buffer pad package 4 is used to deform and buffer the impact caused by the collision. During the deformation of the buffer pad package 4, the position of the buffer skeleton 401 changes, causing the originally corresponding positions of the laser sensing belt 403 and the laser emitter 404 to be misaligned, which also triggers the monitoring of the laser sensing belt 403, and also uses the alarm module for early warning, effectively reducing the monitoring blind spots during the transportation process, and because the collision buffering of the buffer pad package 4 affects the laser sensing belts 403 on both ends at the same time, it is different from the previous monitoring judgment, thereby distinguishing the edge collision alarm from the plane collision alarm.

[0039] The second implementation method:

[0040] Compared with the first embodiment, this embodiment mainly adds a positioning frame 103. The specific newly added structure is as follows, and the remaining structures are consistent with the first embodiment.

[0041] Figure 1 and Figure 7-8As shown, the bottom of the movable lifting platform 101 is movably connected with a positioning frame 103, and the periphery of the positioning frame 103 is provided with cable holes 104, and the slings 102 pass through the cable holes 104. The slings 102 in the cable holes 104 are pulled by the positioning frame 103 to change the lifting position of the slings 102, and the impending collision crisis is quickly resolved. The top ends of the crane body 1 are fixedly connected with supports 105, and hydraulic cylinders 106 are hinged between the four corners of the positioning frame 103 and the supports 105. The horizontal position adjustment of the positioning frame 103 is quickly realized by utilizing the combined extension and contraction of the hydraulic cylinders 106;

[0042] When a plane collision warning and an edge collision alarm are obtained, the horizontal position of the positioning frame 103 is changed by operating the combined extension and contraction changes of the hydraulic cylinder 106, so that the sling 102 in the rope hole 104 is pulled by the positioning frame 103 to change the lifting position of the sling 102, and the material rack 2 is adjusted away from the collision object, so as to quickly resolve the impending collision crisis and provide protection for the automobile parts in the material rack 2.

[0043] Figure 9-10 As shown, the inside of the cable hole 104 is rotatably connected with a shaft ring 107, and one end of the inner wall of the shaft ring 107 is rotatably connected with a pulley 108, and the sling 102 corresponds to the pulley 108. The shaft ring 107 cooperates with the pulley 108 to effectively improve the activity effect of the sling 102 in the cable hole 104, and effectively reduce the wear of the sling 102 and the cable hole 104. The outside of the cable hole 104 is fixedly connected with a lubrication module 109, and the oil delivery end of the lubrication module 109 corresponds to the shaft ring 107. The shaft ring 107 is made of wear-resistant metal material. The lubrication module 109 provides lubricating oil for the shaft ring 107, effectively improving the rotation effect of the shaft ring 107, and the other end of the inner wall of the shaft ring 107 is fixedly connected with an anti-detachment bracket 110, and the outer end of the anti-detachment bracket 110 is in active contact with the pulley 108, and the anti-detachment bracket 110 contacts the pulley 108, effectively preventing the sling 102 on the pulley 108 from detaching;

[0044] The collar 107 cooperates with the pulley 108 to effectively improve the activity effect of the sling 102 in the cable hole 104, so that when the horizontal position of the positioning frame 103 changes, the sling 102 can still stably pass through the cable hole 104, effectively reducing the wear of the sling 102 and the cable hole 104. The lubrication module 109 provides lubricating oil to the collar 107. After lubrication by the lubricating oil, the collar 107 rotates more flexibly, effectively improving the rotation effect of the collar 107. The anti-detachment bracket 110 resists the pulley 108, effectively preventing the sling 102 on the pulley 108 from detaching.

[0045] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
