Detailed Implementation
[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0027] Example 1
[0028] refer to Figures 1-5A non-powered handling device includes a support frame 1, a support arm 2, and hooks 3. The support frame 1 is provided with a rotatable connector 11. The support arm 2 is hinged to the connector 11. One end of the support arm 2 is provided with a suspension member 21, and the other end is provided with a counterweight 22. The free end of the suspension member 21 is provided with an adjustment component 23. There are at least two hooks 3, which are arranged in a relatively opposite manner on the adjustment component 23. The adjustment component 23 is used to adjust the distance between the relatively arranged hooks 3. The hooks 3 are used to hook onto the two sides or both ends of the external frame box.
[0029] It should be noted that the peripheral device's frame has through slots that match the position and number of hook parts 3.
[0030] In the initial state, since no items are hung on the hook 3, the weight of the counterweight 22 will lift one end of the suspension 21. The operator needs to pull down the hook 3 to match the position of the hook 3 with the frame box. According to the size of the frame box, the adjusting component 23 is used to adjust the adjusting component to a suitable distance and insert the hook 3 into the through groove on the frame box to ensure that each hook 3 is in the through groove. After the external force on the hook 3 is removed, the counterweight 22 provides an upward force on the frame box under its own weight. With the assistance of the counterweight 22, the operator helps to lift and move the frame box to the designated position.
[0031] This method reduces labor intensity and improves handling efficiency. Simultaneously, the adjusting component 23 can adjust the distance between the hook pieces 3 to accommodate the handling of crates of different sizes.
[0032] In this embodiment, the adjustment component 23 includes a first frame 231, a second frame 232, and a traction mechanism 233. The first frame 231 and the second frame 232 are arranged crosswise and rotatably connected. One end of the first frame 231 and one end of the second frame 232 are respectively connected to the suspension component 21 through the traction mechanism 233. The hook component 3 is located at the free end of the first frame 231 and the free end of the second frame 232.
[0033] Specifically, the first frame 231 and the second frame 232 are rotatably connected at the intersection. In actual use, the first frame 231 and the second frame 232 form a scissor-shaped structure. That is, the operator can swing the first frame 231 and the second frame 232 to make the ends of the first frame 231 and the second frame 232 move away from each other, so as to adjust the distance between the relatively arranged hooks 3.
[0034] Furthermore, the traction mechanism 233 includes four traction chains 2331, which are arranged in pairs on both sides of the suspension member 21. The two traction chains 2331 on the same side are arranged crosswise, and the two traction chains 2331 on the same side are respectively connected to the first frame 231 and the second frame 232.
[0035] When adjusting the distance between the hooks 3, the operator needs to lift the first frame 231 and the second frame 232 to relax the traction chain 2331, and then move the ends of the first frame 231 and the second frame 232 away from each other to adjust the distance between the relatively arranged hooks 3 until the hooks 3 are inserted into the through groove, and then automatically clamped under the weight of the first frame 231 and the second frame 232 to fix the frame box.
[0036] It should be noted that the purpose of the cross arrangement of the two traction chains 2331 on the same side is to offset the spacing between the two traction chains 2331 on the same side. We found that without the cross arrangement, the two traction chains 2331 cannot contact each other, thus determining the initial distance between the end of the first frame 231 and the end of the second frame 232. In some usage scenarios, the resulting clamping effect is poor. With the cross arrangement, the two traction chains 2331 on the same side have a fulcrum, allowing them to contact each other and resulting in a better clamping effect.
[0037] In this embodiment, the suspension component 21 includes a chain 211 and a connecting plate 212. One end of the support arm 2 is provided with a hook portion 24. One end of the chain 211 is hung on the hook portion 24, and the other end is connected to the connecting plate 212. The traction chains 2331 are all connected to the bottom of the connecting plate 212.
[0038] In practical applications, operators can also choose to use different suspension components 21 according to different frame sizes. Specifically, the chain 211 and the hook part 24 can be disassembled and replaced with a chain 211 of different sizes. Implicitly, the counterweight 22 and the support arm 2 are also detachably connected, and operators can use counterweights 22 of different sizes according to the actual situation.
[0039] Preferably, the support frame 1 is provided with a first connecting piece 12 and a second connecting piece 13 arranged at intervals. The top of the first connecting piece 12 and the bottom of the second connecting piece 13 are respectively provided with a first bearing seat 121 and a second bearing seat 131, and the first bearing seat 121 and the second bearing seat 131 are arranged vertically in correspondence. The connecting piece 11 is rotatably connected to the support frame 1 through the first bearing seat 121 and the second bearing seat 131.
[0040] Specifically, the first bearing housing 121 and the second bearing housing 131 work together to provide stable rotational support for the connector 11. The first connecting piece 12 is mainly used to provide bottom support for the connector 11 and cooperates with the first bearing housing 121 to provide rotational support for the connector 11. The second bearing housing 131 mainly provides rotational support for the middle part of the connector 11 to ensure the stability of the rotation of the connector 11.
[0041] In this embodiment, the connector 11 includes a connecting rod 111 and a U-shaped frame 112. The connecting rod 111 is connected to the bottom of the U-shaped frame 112, and the support arm 2 is hinged to the open end of the U-shaped frame 112. The connecting rod 111 is rotatably connected to the support frame 1.
[0042] Specifically, the connecting rod 111 passes through the second connecting piece 13 and is connected to the second bearing seat 131. The end of the connecting rod 111 is connected to the first bearing seat 121. The support arm 2 is hinged at the open end of the U-shaped frame 112, so that the support arm 2 can swing in the vertical plane to form a lever.
[0043] Preferably, the support frame 1 includes a support rod 14 and a base frame 15. The base frame 15 has a cross-shaped structure, and the support rod 14 is connected to the middle of the base frame 15. The connector 11 is disposed on the support rod 14. In actual use, the cross-shaped structure distributes the load through the intersecting support points, which can effectively enhance the overall strength and stability.
[0044] In this embodiment, the horizontal distance from the suspension member 21 to the connector 11 is greater than the horizontal distance from the counterweight member 22 to the connector 11.
[0045] In this design, simply put, the lever arm of the suspension component 21 is longer than that of the counterweight component 22. After hooking the frame box, the frame box can more easily offset the heavier counterweight.
[0046] Preferably, the hook 3 has an L-shaped structure, including a horizontal part 31 and a vertical part 32. The vertical part 32 is connected to the adjusting component 23, and the horizontal part 31 is used to hook the external frame box. In actual use, the horizontal part 31 is mainly used to hook the frame box, while the vertical part 32 is mainly used to create the clamping effect.
[0047] In a preferred embodiment, the number of hooks 3 is four; in other embodiments, the number of hooks 3 can be six or eight. Of course, the operator can increase the number of hooks 3 according to the actual situation.
[0048] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
