Description

Technical Field

[0001] This utility model relates to a lifting frame, specifically a lifting frame for logistics, and belongs to the field of logistics warehousing technology. Background Technology

[0002] With the development of the modern logistics industry, turnover racks have become very important in logistics warehouses. Logistics turnover racks can ensure the supply and demand of goods between various departments within an enterprise, effectively protect products, and prevent products from being damaged due to mutual squeezing.

[0003] Chinese patent application publication number CN221679688U discloses a turnover rack for logistics, which relates to the field of logistics warehousing technology. The turnover rack for logistics is equipped with a lead screw, which enables the turnover rack to move horizontally up and down. The height of the turnover rack can be adjusted according to the goods. A motor is installed at the lead screw, and the lead screw can be moved up and down automatically by a button. This avoids the uneven rotation on both sides when manually cranking, which would cause the support plate to be unbalanced.

[0004] While the solutions in the aforementioned patents can adjust the height of the turnover rack according to the goods, the turnover racks in the aforementioned patents are not convenient for securing the lifted items when lifting them. The items are prone to sliding during the lifting process, which can easily lead to the items falling and affect the safety of the items during lifting. Furthermore, the angle of the lifting rack cannot be adjusted. Therefore, a lifting rack for logistics is proposed here. Utility Model Content

[0005] This utility model proposes a lifting frame for logistics to solve the problems in the prior art of not being able to fix the lifted items and not being able to adjust the angle of the lifting frame.

[0006] This utility model is achieved through the following technical solution: a lifting frame for logistics, including a positioning plate, a rotating plate being rotatably sleeved inside the positioning plate, and a power mechanism for driving the rotating plate to rotate being provided on the upper surface of the positioning plate.

[0007] Furthermore, the power mechanism includes a first motor fixed to the upper surface of the positioning plate, and a drive wheel fixed to the output end of the first motor. A toothed ring fixedly sleeved around the periphery of the drive wheel is engaged with the drive wheel.

[0008] A lifting frame is provided above the rotating plate, and a support mechanism that drives the lifting frame to rotate is provided between the rotating plate and the lifting frame.

[0009] Furthermore, the support mechanism includes a first connecting plate fixed to the upper surface of the rotating plate and a second connecting plate fixed to the bottom surface of the lifting frame. Two first support rods are rotatably connected to one side of the first connecting plate, and the bottom ends of the two first support rods are provided with interlocking teeth. Two second support rods are rotatably connected to one side of the second connecting plate, and the top ends of the two second support rods are provided with interlocking teeth. The bottom ends of the two second support rods are respectively rotatably connected to the top ends of the two first support rods.

[0010] Furthermore, the support mechanism also includes a second motor fixed to the upper surface of the rotating plate. The output end of the second motor is fixed with a rotating rod. The end of the rotating rod away from the second motor rotates through the first connecting plate and is fixedly sleeved on the bottom end of one of the first support rods.

[0011] A support plate is provided above the lifting frame. Multiple pulleys are evenly arranged on the upper surface of the support plate. Two clamps are provided on both sides of the support plate to fix the items. A positioning mechanism is provided between the support plate and the lifting frame to drive the clamps to move.

[0012] Furthermore, the positioning mechanism includes two limiting holes opened on the top surface of the lifting frame. A positioning rod is fixed inside each limiting hole. A transmission frame is rotatably sleeved around the periphery of each positioning rod. A connecting block fixed to one side of the clamping plate is rotatably connected to the top of each transmission frame. A limiting rod is fixedly sleeved at the bottom of each transmission frame. A tension spring is fixed between the two limiting rods.

[0013] Furthermore, the positioning mechanism also includes a slide rod fixed to the bottom surface of the support plate, the bottom end of which slides through the top surface of the lifting frame and is fixed with a trapezoidal block.

[0014] This utility model provides a lifting frame for logistics, which has the following beneficial effects:

[0015] 1. This lifting frame for logistics uses the weight of the items themselves to press down on the support plate. Through the cooperation between the support plate and the sliding rod, the trapezoidal block can be moved downwards, triggering the transmission frame to rotate around the positioning rod. Through the cooperation between the transmission frame and the connecting block, the clamping plate can be moved, and the items above the support plate can be fixed, preventing the items from moving when the lifting frame moves, thus improving the stability of the items above the lifting frame.

[0016] 2. This lifting frame for logistics, through the cooperation between the first motor, the drive wheel and the gear ring, enables the rotating plate to rotate inside the positioning plate. The angle of the lifting frame supporting the items can be adjusted according to the needs of use, thereby improving the use effect of the lifting frame. Attached Figure Description

The output end of the first motor 31 is fixed with a drive wheel 32. The outer periphery of the drive wheel 32 is engaged with a toothed ring 33 fixedly sleeved on the outer periphery of the rotating plate 2.

[0031] In the above scheme, the rotating plate 2 can rotate inside the positioning plate 1 through the cooperation between the first motor 31, the drive wheel 32 and the gear ring 33.

[0032] Please refer to this carefully. Figure 1 and Figure 3 A lifting frame 4 is provided above the rotating plate 2, and a support mechanism 5 is provided between the rotating plate 2 and the lifting frame 4 to drive the lifting frame 4 to rotate.

[0033] Please refer to this carefully. Figure 3 The support mechanism 5 includes a first connecting plate 51 fixed to the upper surface of the rotating plate 2 and a second connecting plate 54 fixed to the bottom surface of the lifting frame 4. Two first support rods 52 are rotatably connected to one side of the first connecting plate 51. The bottom ends of the two first support rods 52 are provided with intermeshing teeth. Two second support rods 53 are rotatably connected to one side of the second connecting plate 54. The top ends of the two second support rods 53 are provided with intermeshing teeth. The bottom ends of the two second support rods 53 are rotatably connected to the top ends of the two first support rods 52 respectively.

[0034] The support mechanism 5 also includes a second motor 55 fixed on the upper surface of the rotating plate 2. The output end of the second motor 55 is fixed with a rotating rod 56. The end of the rotating rod 56 away from the second motor 55 rotates through the first connecting plate 51 and is fixedly sleeved on the bottom end of one of the first support rods 52.

[0035] In the above scheme, the first support rod 52 can be rotated by the cooperation between the second motor 55 and the rotating rod 56, and the lifting frame 4 can be moved up and down by the cooperation between the first support rod 52 and the second support rod 53.

[0036] Please refer to this carefully. Figure 1 and Figure 4 A support plate 6 is provided above the lifting frame 4. Multiple pulleys 7 are evenly arranged on the upper surface of the support plate 6. Two clamps 8 are provided on both sides of the support plate 6 to fix the items. A positioning mechanism 9 is provided between the support plate 6 and the lifting frame 4 to drive the clamps 8 to move.

[0037] In the above scheme, the positioning mechanism 9 can drive the clamping plate 8 to move and fix the items above the support plate 6.

[0038] Please refer to this carefully. Figure 4 The positioning mechanism 9 includes two limiting holes 91 opened on the top surface of the lifting frame 4. A positioning rod 92 is fixed inside each limiting hole 91. A transmission frame 93 is rotatably sleeved around each positioning rod 92. A connecting block 94 fixed on one side of the clamping plate 8 is rotatably connected to the top of each transmission frame 93. A limiting rod 95 is fixedly sleeved at the bottom of each transmission frame 93. A tension spring 96 is fixed between the two limiting rods 95.

The clamping plate 8 can be moved by the cooperation between the transmission frame 93 and the connecting block 94.

[0041] In use, this invention works as follows: when the item to be lifted passes above the support plate 6, it is supported by the pulley 7, and then the weight of the item presses down on the support plate 6. Through the cooperation between the support plate 6 and the sliding rod 97, the trapezoidal block 98 moves downward, triggering the transmission frame 93 to rotate around the positioning rod 92. Through the cooperation between the transmission frame 93 and the connecting block 94, the clamping plate 8 moves, fixing the item above the support plate 6 and preventing movement of the item during the lifting frame's movement, thus improving the stability of the item's position above the lifting frame. When the item moves out of the support plate 6, the tension spring 96 acts as a limiting rod 9. 5 provides elastic tension and drives the trapezoidal block 98 and slide bar 97 to reset; after the item is fixed above the lifting frame 4, the second motor 55 is started. Through the cooperation between the second motor 55 and the rotating rod 56, the first support rod 52 can be rotated. Through the cooperation between the first support rod 52 and the second support rod 53, the lifting frame 4 can be moved up and down to adjust the height of the lifting frame; then the first motor 31 is started. Through the cooperation between the first motor 31, the drive wheel 32 and the gear ring 33, the rotating plate 2 can be rotated inside the positioning plate 1. The angle of the lifting frame supporting the item can be adjusted according to the needs of use, improving the practicality of the lifting frame.
