Description

Technical Field

[0001] This application relates to the field of lifting devices, and more specifically, to a traction motor lifting device stabilization mechanism. Background Technology

[0002] Traction motor spreaders are devices that use an electric motor as a power source and connect to a spreader via a wire rope or traction rope to achieve vertical lifting or horizontal traction of heavy objects. These include pallet spreaders, which are specialized devices used for lifting and transporting pallets. They are typically used in conjunction with cranes, gantry cranes, and other equipment to achieve efficient and safe lifting and transport of pallets and the goods they carry.

[0003] In the prior art, when using pallet spreaders, since the weight distribution of goods on the pallet may not be uniform, multiple sets of positions for placing lifting rings are set on the crossbeam of the pallet spreader to keep the pallet balanced when it is lifted.

[0004] However, the existing water injection devices still have the following shortcomings in use: the existing pallet lifting devices generally do not have an anti-fall mechanism, which makes the pallet easy to tilt when it is unknown which side is heavier and the position of the lifting ring has not been adjusted. The items placed on the pallet are easy to tip over and fall off the pallet, and the goods need to be manually placed back on the pallet. Utility Model Content

[0005] To overcome the above deficiencies, this application provides a traction motor lifting device stabilization mechanism, which aims to improve the problem that pallets are prone to tilting, and items placed on the pallet are prone to tipping over and falling off the pallet, requiring manual repositioning of the goods on the pallet.

[0006] This application provides a traction motor lifting device stabilization mechanism, including a pallet lifting device. One side of the pallet lifting device is provided with an anti-fall mechanism to prevent objects on the pallet from falling off, and another side of the pallet lifting device is provided with an adjustment mechanism to adapt to pallets of different sizes.

[0007] The anti-fall mechanism includes multiple sets of slots, which are located on the top of the pallet lifting device. A through hole is provided on the top of the pallet lifting device, and a second horizontal plate is movably inserted into the through hole.

[0011] In the above implementation process, by setting the threaded column, the threaded column can be rotated by turning the adjustment knob, thereby moving the threaded column inside the vertical plate.

[0012] In one specific implementation, the other end of the threaded post is threaded into the interior of a threaded hole.

[0013] In the above implementation process, by setting the threaded hole, one end of the threaded column can be threaded into the inside of the threaded hole, the fastener can be fixed to one side of the vertical plate, and then the second horizontal plate can be fixed inside the through hole.

[0014] In one specific implementation, the adjusting mechanism includes a housing connected inside a first horizontal plate, a first motor connected to one side of the housing, an output shaft of the first motor passing through the housing and connected to a screw, and the other end of the screw being rotatably connected inside the housing.

[0015] In the above implementation process, by setting up the first motor, the output shaft of the first motor can be controlled to rotate, thereby driving the screw to rotate inside the housing.

[0016] In one specific implementation, the outer surface of the screw is threadedly connected to a threaded seat, which is slidably connected inside the housing.

[0017] In the above implementation process, by setting up the threaded seat, the threaded seat can be driven to slide inside the first housing when the screw rotates.

[0018] In one specific implementation, a first cross plate is connected to one side of the threaded seat.

[0019] In the above implementation process, by setting the first horizontal plate, the first threaded seat can drive the first horizontal plate to move, thereby adjusting the distance between the two sets of first horizontal plates, so that it can fit the outer surface of the pallet when encountering pallets of different widths.

[0020] In one specific implementation, the first horizontal plate has a cavity inside, and a fourth horizontal plate is slidably connected to the inner wall of the cavity. One end of the fourth horizontal plate passes through the first horizontal plate and is slidably connected to a third horizontal plate.

[0021] In the above implementation process, the cavity allows the fourth horizontal plate to slide inside the cavity, thereby adjusting the distance between the second and third horizontal plates.

[0022] In one specific implementation, the inner wall of the cavity is connected to multiple sets of electrically operated telescopic rods, and the other end of the electrically operated telescopic rods is connected to one side of the fourth horizontal plate.

[0023] In the above implementation process, by setting up an electric telescopic rod, the fourth horizontal plate can be slid inside the cavity by controlling the electric telescopic rod.

[0024] In one specific implementation, a clip is connected to the bottom of the third horizontal plate, and the clip is movably inserted into the inside of the slot.

[0025] In the above implementation process, by setting multiple sets of card slots, the card can be inserted into the inside of the card slots, and the third horizontal plate can be fixed above the pallet hanger, which can be adapted to pallets of various lengths.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the anti-fall mechanism and the adjustment mechanism, the goods on the pallet can be prevented from falling off when the pallet is tilted by the first horizontal plate, the second horizontal plate, the third horizontal plate and the fourth horizontal plate. Furthermore, by controlling the first motor and the electric telescopic rod, the first horizontal plate, the second horizontal plate, the third horizontal plate and the fourth horizontal plate can be made to fit with pallets of various lengths and widths, thereby solving the problem that the pallet is prone to tilting, and the items placed on the pallet are prone to tipping over and falling off the pallet, requiring manual repositioning of the goods on the pallet.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a traction motor lifting device stabilization mechanism, including a pallet lifting device 1.

[0039] Please see Figure 1 and Figure 2 One side of the pallet spreader 1 is provided with an anti-fall mechanism 2 to prevent objects on the pallet from falling off, and one side of the pallet spreader 1 is provided with an adjustment mechanism 3 to adapt to pallets of different sizes.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The anti-fall mechanism 2 includes multiple sets of slots 205, which are opened on the top of the pallet lifting device 1. A through hole 204 is opened through the top of the pallet lifting device 1, and a second horizontal plate 202 is movably inserted into the through hole 204.

[0041] In a specific configuration, one end of the second horizontal plate 202 is connected to a fixing member 209, and a threaded hole 2010 is provided through one side of the fixing member 209. With the fixing member 209, after the second horizontal plate 202 is inserted into the through hole 204, the second horizontal plate 202 can be fixed inside the through hole 204 by the fixing member 209.

[0042] In the specific setup, the top of the pallet spreader 1 is connected to a vertical plate 207, and the inside of the vertical plate 207 is connected to a threaded post 208. One end of the threaded post 208 is connected to an adjustment knob 206. By rotating the adjustment knob 206, the threaded post 208 can be rotated, causing it to move inside the vertical plate 207.

[0043] In a specific configuration, the other end of the threaded post 208 is threaded into the inside of the threaded hole 2010. By setting the threaded hole 2010, the fastener 209 can be fixed to one side of the vertical plate 207 by threading one end of the threaded post 208 into the inside of the threaded hole 2010, thereby fixing the second horizontal plate 202 inside the through hole 204.

[0044] In a specific configuration, the adjustment mechanism 3 includes a housing 301, which is connected inside the first horizontal plate 201. A first motor 302 is connected to one side of the housing 301. The output shaft of the first motor 302 passes through the housing 301 and is connected to a screw 304. The other end of the screw 304 is rotatably connected inside the housing 301. By controlling the output shaft of the first motor 302, the screw 304 can be rotated inside the housing 301.

[0045] In a specific configuration, the outer surface of the screw 304 is threadedly connected to a threaded seat 303, which is slidably connected inside the housing 301. The threaded seat 303 allows the screw 304 to rotate, thereby causing the threaded seat 303 to slide inside the first housing 301.

[0046] In a specific configuration, a first horizontal plate 201 is connected to one side of the threaded seat 303. The first horizontal plate 201 can be moved by the first threaded seat 303, thereby adjusting the distance between the two sets of first horizontal plates 201 so that it can fit the outer surface of the pallet when encountering pallets of different widths.

[0047] In a specific configuration, a cavity 306 is provided inside the first horizontal plate 201. A fourth horizontal plate 2012 is slidably connected to the inner wall of the cavity 306. One end of the fourth horizontal plate 2012 passes through the first horizontal plate 201 and is slidably connected to the third horizontal plate 203. The cavity 306 allows the fourth horizontal plate 2012 to slide inside the cavity 306, thereby adjusting the distance between the second horizontal plate 202 and the third horizontal plate 203.

[0048] In a specific configuration, the inner wall of the cavity 306 is connected to multiple sets of electric telescopic rods 305. The other end of the electric telescopic rods 305 is connected to one side of the fourth horizontal plate 2012. By setting the electric telescopic rods 305, the fourth horizontal plate 2012 can be slid inside the cavity 306 by controlling the electric telescopic rods 305.

[0049] In specific settings, the bottom of the third horizontal plate 203 is connected to a clip 2011, which is movably inserted into the inside of the slot 205. By setting multiple slots 205, the clip 2011 can be inserted into the inside of the slot 205 to fix the third horizontal plate 203 above the pallet hanger 1, which can accommodate pallets of various lengths.

[0050] The working principle of this traction motor lifting device stabilization mechanism is as follows: When using the traction motor lifting device stabilization mechanism, the second horizontal plate 202 is inserted into the through hole 204, and the clamp 2011 is inserted into the slot 205. Then, by rotating the adjustment knob 206, the threaded post 208 is moved inside the vertical plate 207, so that one end of the threaded post 208 is threaded into the threaded hole 2010, fixing the fixing member 209 to one side of the vertical plate 207. This further fixes the second horizontal plate 202 inside the through hole 204. Through the first horizontal plate 201, the second horizontal plate 202, the third horizontal plate 203, and the fourth horizontal plate 2012, the goods on the pallet are prevented from falling when the pallet is tilted. Furthermore, by controlling the first motor 302 to drive the screw 304 to rotate, the screw... The movement of the tray seat 303 moves the first horizontal plate 201, allowing adjustment of the distance between the two sets of first horizontal plates 201 to accommodate pallets of various widths. By controlling the electric telescopic rod 305, the fourth horizontal plate 2012 can slide along the inner wall of the cavity 306 opened in the first horizontal plate 201, adjusting the distance between the second horizontal plate 202 and the third horizontal plate 203. Through the setting of multiple sets of slots 205, the clip 2011 can be inserted into the slot 205 to fix the third horizontal plate 203 above the pallet hanger 1. This can accommodate pallets of various lengths, thus solving the problem that pallets are prone to tilting, and items placed on the pallet are prone to tipping over and falling off the pallet, requiring manual repositioning of goods.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
