[0036] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0037] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0038] Example 1, referring to Figure 1 The first embodiment of this utility model provides a material rack lifting device, including a lifting platform 100 and a clamping assembly 200.

[0039] The hoisting platform 100 includes installation components 101;

[0040] The clamping assembly 200 has two sets, which are respectively disposed at both ends of the mounting member 101. The clamping assembly 200 includes a boom 201 rotatably disposed at the end of the mounting member 101 and a gripper 202 disposed at the bottom of the boom 201.

[0041] Mounting component 101 is elongated and has grooves. The lifting device uses these grooves to hook onto the material rack lifting device, which is used to move the material rack lifting device to achieve the purpose of transferring the material rack. The boom 201 is elongated and is located on both sides of mounting component 101. The distance between the two lifting devices 201 can be adjusted to adapt to the size of the material rack, so that the gripper 202 can hook onto the crossbeam of the material rack to fix the material rack. The bottom of the boom 201 is rotatably connected to the gripper 202, which is used to hook onto the crossbeams on both sides of the material rack to fix the material rack on the material rack lifting device.

[0042] Furthermore, the mounting component 101 is provided with a lifting ring 102.

[0043] During use, the operator uses the hook of the lifting device to hook onto the groove or lifting ring 102 on the mounting part 101, moves the material rack lifting device to the position where the material rack is placed, and adjusts the distance between the two sides of the lifting arm 201 by rotating the boom 201. The distance between the two sides of the lifting arm 201 is adjusted to suit the size of the material rack to be transferred. The operator lowers the material rack lifting device and adjusts the position of the gripper 202 of the boom 201 to hook onto the crossbeam of the material rack. When the gripper 202 is stably hooked onto the material rack, the operator lifts the material rack lifting device and lifts the material rack to the target position. After lowering the material rack lifting device, the operator rotates the boom 201 to disengage the gripper 202 from the crossbeam of the material rack, thus completing the transfer of the material rack.

[0044] Example 2, refer to Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the boom 201 is T-shaped and the bottom of the boom 201 is rotatably connected to two grippers 202.

[0045] The end of the boom 201 is rotatably connected to the mounting member 101. The T-shaped structure of the boom 201 includes a longitudinally extending vertical part and a laterally extending horizontal part. The upper end of the vertical part is rotatably connected to both sides of the mounting member 101, the lower end of the vertical part is fixedly connected to the center point of the horizontal part, and the two ends of the horizontal part are rotatably connected to the grippers 202.

[0046] The remaining structure is the same as that in Example 1.

[0047] During use, the distance between the two sides of the boom 201 is adjusted by rotating the vertical part of the boom 201. The spacing between the booms 201 on both sides of the mounting part 101 is adjusted to suit the size of the material rack to be transferred. The operator lowers the material rack lifting device and adjusts the position of the two grippers 202 connected to the booms 201 on both sides to hook the crossbeam of the material rack.

[0048] In this embodiment, two grippers 202 are rotatably connected to the bottom of the T-shaped booms 201 on both sides. The T-shaped booms 201 allow the material rack lifting device to maintain better balance. The two grippers 202 on each side have four force points when hooking the material rack, which can better fix the material rack and better maintain a horizontal state when transferring the material rack lifting device.

[0049] Example 3, referring to Figure 3 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the mounting component 101 is square, the boom 201 is H-shaped, and two grippers 202 are rotatably connected to the bottom of the boom 201.

[0050] The mounting component 101 has two protrusions at each end, which are rotatably connected to the boom 201.

[0051] The end of the boom 201 has two mounting points, which are rotatably connected to two protruding pins at one end of the mounting component 101. Similarly, the end of the other boom 201 is rotatably connected to two protruding pins at the other end of the mounting component 101.

[0052] The remaining structure is the same as that in Example 1.

[0053] During use, the distance between the two H-shaped booms 201 is adjusted by rotating the H-shaped boom 201. The spacing between the H-shaped booms 201 on both sides of the mounting part 101 is adjusted to suit the size of the material rack to be transferred. The operator lowers the material rack lifting device and adjusts the position of the two grippers 202 connected to the two H-shaped booms 201 on both sides to hook onto the crossbeam of the material rack.

[0054] In this embodiment, the mounting component is set to square and the boom 201 is set to H-shape, which can greatly prevent the material rack from moving or shifting during the transfer of the material rack, so that the material rack can always maintain a balanced state and keep the material rack in a horizontal state during the transfer of the material rack.

[0055] Example 4, refer to Figure 4 This is the fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the gripper 202 is hook-shaped or L-shaped, and the gripper 202 is provided with a slot 202a, which cooperates with the boom 201. In addition, a polyurethane protective block is provided on the inner surface of the gripper 202.

[0056] The gripper 202 is hook-shaped or L-shaped, which makes it easy for the gripper 202 to hook onto the crossbeams on both sides of the material rack and fix the material rack on the material rack lifting device.

[0057] The upper end of the gripper 202 is rotatably connected to the boom 201. A slot 202a is provided in the middle of the upper part of the gripper 202. When the gripper 202 is not in use, after rotating the gripper 202 upward, the slot 202a engages with the boom 201, fixing and retracting the gripper 202. When the gripper 202 is in use, after rotating the gripper 202 downward, the slot 202a of the gripper 202 abuts against the boom 201 to fix the position of the gripper 202.

[0058] Furthermore, a polyurethane protective block is provided on the surface of the gripper 202, which can effectively absorb the energy of vibration, impact or drop of the material rack and protect the structure of the gripper 202 from damage.

[0059] The remaining structure is the same as that in Example 1.

[0060] During use, the operator uses the hook of the lifting device to hook the groove or lifting ring 102 on the mounting part 101, moves the material rack lifting device to the position where the material rack is placed, and adjusts the distance between the two sides of the lifting arm 201 by rotating the boom 201. The distance between the two sides of the lifting arm 201 on the mounting part 101 is adjusted to adapt to the size of the material rack to be transferred. The operator lowers the material rack lifting device and rotates the jaws 202 of the two sides of the lifting arm 201 downwards, so that the slots 202a of the jaws 202 abut against the lifting arm 201 to fix the position of the jaws 202. The operator rotates the two sides of the lifting arm 201 respectively, so that the jaws 202 hook onto the crossbeam of the material rack. When the jaws 202 are stably hooked onto the material rack, the operator lifts the material rack lifting device and lifts the material rack to the target position. After lowering the material rack lifting device, the operator rotates the boom 201 to disengage the jaws 202 from the crossbeam of the material rack, thus completing the transfer of the material rack.

[0061] Example 5, refer to Figure 5 , Figure 6 This is the fifth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the clamping assembly 200 further includes a rotating member 203. The rotating member 203 is configured in two sets. The upper part of the rotating member 203 is rotatably connected to both sides of the hoisting platform 100, and the lower end of the rotating member 203 is rotatably connected to the end of the boom 201.

[0062] The upper part of the rotating component 203 is rotatably connected to both sides of the mounting component 101, and the lower end of the rotating component 203 is rotatably connected to the end of the boom 201. The rotating component 203 is positioned between the mounting component 101 and the boom 201. The distance between the two sets of booms 201 is adjusted by the rotating component 203 so that the distance between the two sets of booms 201 is adapted to the size of the material rack. The boom 201 hooks onto the material rack through a small range of adjustment.

[0063] Furthermore, the rotating component 203 includes a connecting arm 203a rotatably mounted at the end of the mounting component 101, and a crossbar 203b disposed between the two connecting arms 203a. One end of the crossbar 203b is connected to the top of the connecting arm 203a, and the other end of the crossbar 203b is connected to the middle section of the other connecting arm 203a. The middle section of the crossbar 203b is rotatably connected to the middle of the mounting component 101. When the lifting device transfers the material rack, under the action of gravity, the crossbar 203b adjusts the rotating components 203 on both sides of the mounting component 101 to maintain the same horizontal height, thereby keeping the two lifting arms 201 at the same height. Under the action of gravity, the lifting arms 201 can maintain a vertical state and stably clamp the material rack, avoiding the tilting of the lifting arms 201 and keeping the material rack in a horizontal state.

[0064] Furthermore, the connecting arm 203a is H-shaped, and the middle part of the connecting arm 203a is rotatably connected to the mounting part 101; there are two crossbars 203b, which are located on both sides of the connecting arm 203a respectively.

[0065] The connecting arm 203a is H-shaped, and its middle part is rotatably connected to two protrusions at both ends of the mounting part 101. The connecting arm 203a is inserted into the protrusions, and its middle part is connected to the connecting hole of the protrusion through a pin. The crossbar 203b can be set inside the mounting part 101 of the connecting arm 203a or outside the mounting part 101 of the connecting arm 203a. The two ends of the crossbar 203b are respectively connected to the connecting arms 203a on both sides of the mounting part 101. When the lifting rack is used to transfer the material rack, under the action of gravity, the crossbar 203b adjusts the rotating parts 203 on both sides of the mounting part 101 to keep them at the same horizontal height, thereby ensuring that the connecting arms 203a are kept at the same height.

[0066] The remaining structure is the same as that in Example 1.

[0067] The operator uses the hook of the lifting device to engage the groove or lifting ring 102 on the mounting component 101, moving the material rack lifting device to the position where the material rack is placed. By rotating the upper part of the rotating component 203, the distance between the two sets of rotating components 203 is adjusted. The rotating components 203 on both sides of the mounting component 101 drive the two side booms 201 to adjust their distance, adjusting the spacing of the booms 201 on both sides of the mounting component 101 to suit the size of the material rack to be transferred. The operator lowers the material rack lifting device, rotates the jaws 202 of the two side booms 201 downwards, so that the slots 202a of the jaws 202 abut against the fixed position of the jaws 202 on the booms 201. The operator rotates the two side booms 201 respectively, allowing the jaws 202 to engage with the crossbeam of the material rack. Once the jaws 202 are stably engaged with the material rack, the operator lifts the material rack lifting device. Under the action of gravity, the rotating parts 203 on both sides of the crossbar 203b adjusting mounting part 101 are kept at the same horizontal height, so that the two sides of the boom 201 are kept at the same height. Under the action of gravity, the boom 201 can maintain a vertical state and maintain a stable gripping of the material rack, avoiding the tilting of the boom 201. The material rack is lifted to the target position. After the material rack lifting device is lowered, the boom 201 is rotated to make the gripper 202 disengage from the crossbeam of the material rack. At this time, the transfer of the material rack is completed.
