Description

Technical Field

[0001] This utility model relates to the technical field of aluminum processing, and in particular to an aluminum rod lifting clamp. Background Technology

[0002] Aluminum bars, as an important non-ferrous metal material, are widely used in construction, aerospace, transportation, electronics and other fields. With the continuous growth in demand for aluminum bars, their hoisting technology has become particularly important.

[0003] In the processing and manufacturing of large aluminum plates, large aluminum bars, plates, or ingots are often used as raw materials. Lifting these large aluminum bars is an essential step in this process. Current technology presents several problems in lifting large aluminum bars: First, due to the significant mass of large aluminum bars or plates, lifting fixtures, to ensure sufficient strength, often also have considerable mass and volume. Manually moving the grippers during clamping and positioning the aluminum bars is difficult, especially for workers with less strength, severely impacting processing efficiency and posing safety hazards. Second, some existing fixtures are equipped with drive mechanisms to replace manual force, but this adds extra mass and volume to the existing fixtures. Furthermore, the significant impact during lifting large workpieces requires the drive mechanism's transmission components to withstand substantial impact loads, making them prone to damage and downtime. Therefore, it is necessary to research and develop a lifting fixture that saves manpower without introducing complex transmission components to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides an aluminum bar lifting clamp, which aims to solve the problems of complex and laborious operation by personnel and low efficiency caused by the complex structure of the lifting clamp during the lifting of large aluminum bars.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model proposes an aluminum rod lifting clamp, comprising a lifting body, a gripper assembly, and an adjustment mechanism. The lifting body is provided with a sliding groove, and the gripper assembly is slidably disposed in the sliding groove and connected to the adjustment mechanism. The adjustment mechanism can drive the gripper assembly to reciprocate along the sliding groove to adjust the distance between the center of the gripper assembly and the center of the lifting body. The lifting body is provided with a positioning structure, which can fix the position of the gripper assembly within the sliding groove to accommodate the lifting of aluminum rods of different diameters.

[0008] A further technical solution involves the lifting device body comprising a fixed plate and multiple crossbeams. The multiple crossbeams are arranged radially around the center of the fixed plate, and multiple gripper assemblies are arranged corresponding to each crossbeam. Along the length of the crossbeams, a sliding groove is vertically disposed on the crossbeams. Each gripper assembly includes a gripper and a support block. The gripper is movably disposed within the sliding groove and fixedly connected to the support block. The support block is located above the sliding groove and connected to the adjustment mechanism.

[0009] A further technical solution is that the adjustment mechanism includes a rotating wheel, a mounting plate, and a lead screw. The mounting plate is fixed to the end of the crossbeam away from the fixed plate and protrudes upward from the crossbeam. The protruding mounting plate is provided with a screw hole, and the lead screw is drivenly connected to the screw hole. One end of the lead screw is connected to the rotating wheel, and the other end is rotatably connected to the support block.

[0010] A further technical solution involves the positioning structure including a pin and multiple fixing holes on the crossbeam. Along the length of the crossbeam, the fixing holes are arranged to form multiple fixing positions, each for suspending aluminum bars of different diameters. At least two limiting holes are provided above the gripper. When the gripper slides along the groove to different fixing positions, the fixing holes and the limiting holes are connected by the pin to secure the gripper assembly.

[0011] A further technical solution is that the fixed disk includes an upper disk and a lower disk; one end of each of the plurality of crossbeams is disposed between the upper disk and the lower disk, and each crossbeam is arranged radially along the upper disk or the lower disk.

[0012] A further technical solution is that a lifting ring is fixed above the upper disc, and a reinforcing block is provided at the connection between the lifting ring and the upper disc.

[0013] A further technical solution is that the crossbeam includes a first crossbeam and a second crossbeam, the first crossbeam and the second crossbeam are arranged back to back and the gap between them constitutes the slide groove.

[0014] A further technical solution is that the first crossbeam and the second crossbeam are C-shaped beams, and the fixing hole is opened in the center of the web of the C-shaped beam.

[0015] (III) Beneficial Effects

[0016] The beneficial effects of this utility model are:

[0017] The aluminum rod lifting fixture provided in this embodiment uses an adjusting mechanism to drive the gripper assembly to reciprocate within a slide groove, while a positioning structure fixes the position of the gripper assembly. This achieves effective clamping and lifting of aluminum rods of different diameters, improving the stability and adaptability of the lifting process. The adjusting mechanism precisely adjusts the distance between the gripper assembly and the center of the lifting fixture body, and the positioning structure firmly and reliably fixes the gripper assembly in the corresponding position of the slide groove. Furthermore, the stable clamping of the lifting fixture reduces safety hazards during the lifting process, ensuring the safety of the workers. The lifting fixture body, gripper assembly, and adjusting mechanism have a compact structure, ensuring both the strength and rigidity of the fixture while reducing its weight, thus improving the efficiency of the workers' lifting operations.

Detailed Implementation

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This embodiment provides an aluminum rod lifting clamp, such as Figures 1-2 As shown, the device includes a lifting body 1, a gripper assembly 2, and an adjusting mechanism 3. The lifting body 1 has a sliding groove 4. The gripper assembly 2 is slidably disposed in the sliding groove 4 and connected to the adjusting mechanism 3. The adjusting mechanism 3 can drive the gripper assembly 2 to reciprocate along the sliding groove 4 to adjust the distance between the center of the gripper assembly 2 and the center of the lifting body 1. The lifting body 1 has a positioning structure 5, which can fix the position of the gripper assembly 2 within the sliding groove 4 to accommodate the lifting of aluminum bars of different diameters.

[0025] It should be noted that the aluminum rods in this solution are large aluminum rods, specifically aluminum rods or ingots with a radial length equal to or greater than their axial length.

[0026] The aluminum rod lifting fixture provided in this embodiment achieves effective clamping and lifting of aluminum rods of different diameters through the adjustment mechanism 3 driving the gripper assembly 2 to reciprocate within the slide groove 4, and the positioning structure 5 fixing the position of the gripper assembly 2, thereby improving the stability and adaptability of the lifting process. The adjustment mechanism 3 can precisely adjust the distance between the gripper assembly 2 and the center of the lifting fixture body 1, and the positioning structure 5 allows the gripper assembly 2 to be fixed in the slide groove 4. This means that the fixture can be adjusted and fixed according to aluminum rods of different diameters, greatly enhancing its adaptability. Whether the aluminum rod is small or large diameter, it can be lifted safely and stably using this fixture. Because the fixture can quickly adapt to aluminum rods of different diameters, the time spent changing fixtures during the lifting process is reduced, improving lifting efficiency. At the same time, stable clamping also reduces safety hazards during the lifting process, ensuring the safety of the operators. The fixture's lifting fixture body 1, gripper assembly 2, and adjustment mechanism 3 are reasonably designed and compactly structured, ensuring both the strength and rigidity of the fixture while reducing its weight.

[0027] Specifically, in this embodiment, the lifting device body 1 includes a fixed plate 11 and multiple crossbeams 12. The multiple crossbeams 12 are arranged radially around the center of the fixed plate 11, and multiple gripper assemblies are arranged one-to-one with each crossbeam 12. Along the length of the crossbeam 12, a sliding groove 4 is arranged vertically through the crossbeam 12. Each gripper assembly 2 includes a gripper 21 and a support block 22. The gripper 21 is movably disposed within the sliding groove 4 and fixedly connected to the support block 22. The support block 22 is located above the sliding groove 4 and connected to the adjustment mechanism 3.

[0028] Multiple crossbeams 12 are arranged radially around the center of the fixed plate 11, optimizing space utilization and enabling the lifting device body 1 to better adapt to different working environments and space constraints during lifting. At the same time, the slide 4 is arranged along the length of the crossbeams 12, providing sufficient movement space for the gripper assembly 2 and ensuring smooth lifting.

[0029] Specifically, in this embodiment, the adjustment mechanism 3 includes a rotating wheel 31, a mounting plate 32, and a lead screw 33. The mounting plate 32 is fixed to the end of the crossbeam 12 away from the fixed plate 11 and protrudes upward from the crossbeam 12. The protruding mounting plate 32 is provided with a screw hole, and the lead screw 33 is drivenly connected to the screw hole. One end of the lead screw 33 is connected to the rotating wheel 31, and the other end is rotatably connected to the support block 22.

[0030] Operators can adjust the position of the gripper assembly 2 simply by rotating the rotating wheel 31, without the need for complex mechanical operations or adjustments. This not only reduces the difficulty and labor intensity of operation but also improves the efficiency of hoisting operations. The adjustment mechanism 3 has a compact design. The mounting plate 32 is fixed to the end of the crossbeam 12 away from the fixed plate 11 and protrudes upward from the crossbeam 12. This design saves space and ensures the stability of the structure. At the same time, the connection between the lead screw 33 and the screw hole and support block 22 is also very simple and reliable, facilitating maintenance and replacement.

[0031] Specifically, in this embodiment, the positioning structure 5 includes a pin 51 and multiple fixing holes 52 provided on the crossbeam 12. Along the length of the crossbeam 12, the multiple fixing holes 52 are arranged to form multiple fixing positions, each of which is used to suspend aluminum bars of different diameters. At least two limiting holes 211 are provided above the gripper 21. When the gripper 21 slides along the slide groove 4 to different fixing positions, the fixing holes 52 and the limiting holes 211 are connected by the pin 51 to fix the gripper assembly 2.

[0032] When the gripper 21 slides to a specific fixed position, the fixing hole 52 and the limiting hole 211 are connected by the pin 51, which can firmly fix the position of the gripper assembly 2. This design effectively prevents the gripper assembly 2 from moving or shaking due to external forces during hoisting, enhances the stability of hoisting, greatly simplifies the operation process, and reduces the difficulty and complexity of operation.

[0033] Specifically, in this embodiment, the fixing disk 11 includes an upper disk 111 and a lower disk 112; one end of each of the plurality of crossbeams 12 is disposed between the upper disk 111 and the lower disk 112, and each crossbeam 12 is arranged radially along the upper disk 111 or the lower disk 112. The design of the upper disk 111 and the lower disk 112 provides ample installation space for the crossbeams 12, allowing the crossbeams 12 to be more rationally distributed across the entire fixing disk 11.

[0034] Specifically, in this embodiment, a lifting ring 6 is fixed above the upper disc 111, and a reinforcing block 7 is provided at the connection between the lifting ring 6 and the upper disc 111. The reinforcing block 7 can significantly increase the connection strength between the lifting ring 6 and the upper disc 111, preventing the connection from breaking or being damaged due to excessive force during hoisting. The reinforcing block 7 is usually made of high-strength material, capable of withstanding large tensile and compressive forces, thereby ensuring the stability and reliability of the entire hoisting structure.

[0035] Specifically, in this embodiment, the crossbeam 12 includes a first crossbeam 121 and a second crossbeam 122, which are arranged back-to-back with the gap between them forming a sliding groove 4. The first crossbeam 121 and the second crossbeam 122 are C-shaped beams, with a fixing hole 52 in the center of the web of each C-shaped beam. Both the first crossbeam 121 and the second crossbeam 122 are C-shaped beams, preferably channel steel. The gap between the first crossbeam 121 and the second crossbeam 122 forms the sliding groove 4, providing a smooth sliding track for the gripper assembly 2. This design not only simplifies the structure of the sliding groove 4 but also reduces manufacturing costs.

[0036] In summary, the aluminum rod lifting clamp proposed in this embodiment is used as follows:

[0037] First, connect the lifting fixture to the lifting equipment in the workshop and move the lifting fixture to the corresponding workstation. Then, adjust the adjusting mechanism 3 according to the diameter or specifications of the aluminum rod to be lifted. The worker manually adjusts the rotating wheel 31 so that the gripper 21 of the claw assembly 2 matches the diameter of the workpiece, until the hook below the gripper 21 hooks onto the bottom surface of the workpiece. With the engagement secure, insert the pin 51 into the corresponding fixing hole 52 to prevent the claw assembly 2 from slipping. At this point, the lifting equipment can be started to lift the workpiece and transport it to the next process station.

[0038] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.
