Description

Technical Field

[0001] This utility model relates to the field of material cake lifting tools, and in particular to a special lifting tool for material cakes. Background Technology

[0002] After the spoke blanks arrive at the factory, they are stacked on the rollers in piles of 25, with each blank weighing up to 20 kg. Currently, operators handle them one by one to the roller conveyor, which is inefficient and cannot meet the production capacity of two spinning machines simultaneously. This method poses safety hazards, and the workload per shift is as high as 1500 times, resulting in extremely high labor intensity for operators and numerous complaints. Utility Model Content

[0003] In view of this, the present invention aims to provide a special lifting device for material cakes. This lifting device can penetrate deep into the bottom of the material cake through the central hole. When the lifting device is under load, its two movable rods open outward around the central hinge point to form an X-shaped structure, so that the bottom locking block clamps the inner wall of the material cake. Subsequently, the grabbed material cake can be transferred as a whole to the roller conveyor by a crane or other lifting equipment, thereby significantly reducing the labor intensity of the operator and improving the handling efficiency.

[0004] To achieve the above objectives, the present invention provides a special lifting device for material cakes, comprising: a lifting ring and at least one lifting device assembly; the top of the lifting device assembly is connected to the lifting ring via a first hinge shaft; each lifting device assembly includes: two connecting rods, the top ends of which are hinged to each other via the first hinge shaft; two movable rods, the middle portions of which are hinged to each other via a third hinge shaft; the top end of each movable rod is hinged to the bottom end of the corresponding connecting rod via a second hinge shaft; each movable rod has a radially outwardly extending locking block at its bottom, with the two locking blocks positioned opposite each other; in the initial state, the lower ends of the two movable rods are in a retracted state, forming a Y-shaped structure; when the lifting device is under load, the movable rods rotate around the third hinge shaft, their lower ends opening outwards while their upper ends synchronously retract inwards, thereby driving the locking blocks to clamp the bottom of the material cake.

[0005] Furthermore, each link has an elongated groove at its bottom end; the second hinge shaft passes through the elongated groove and can move along the axial direction of the elongated groove.

[0006] Furthermore, each link includes a straight rod portion and a hinge portion, with the straight rod portion and the hinge portion being set at an angle; an elongated slot is formed on the hinge portion.

[0007] Furthermore, the included angle between the straight rod and the hinged part is 100°~160°.

[0008] Furthermore, the movable rod includes a connecting part and a clamping part, both set at a second preset angle; the top end of the connecting part is connected to the hinge part via a second hinge shaft, and its bottom end is hinged to the top of the clamping part via a third hinge shaft; a locking block is disposed at the bottom of the clamping part and extends radially outward.

[0009] Furthermore, the included angle between the connecting part and the clamping part is 100°~150°.

[0010] Furthermore, there are two lifting assemblies, namely a first lifting assembly and a second lifting assembly; the top ends of the two lifting assemblies are hinged together by a first hinge shaft; the connecting rod of the first lifting assembly, the movable rod of the first lifting assembly, the movable rod of the second lifting assembly, and the connecting rod of the second lifting assembly, all located on the same side, are hinged together by a second hinge shaft, and the second hinge shaft passes through the elongated groove at the bottom end of the two connecting rods.

[0011] Furthermore, the middle parts of the two connecting rods of the first spreading assembly are respectively connected to the middle parts of the corresponding two connecting rods in the second spreading assembly via a first connecting shaft and a second connecting shaft.

[0012] Furthermore, the lifting device also includes a support rod, the first end of which is connected to the first connecting shaft, and the second end of which is provided with a slot that can be engaged with the second connecting shaft.

[0013] Furthermore, the lifting device also includes a limiting groove with a clearance hole; the movable rod passes through the clearance hole and is connected to the limiting groove via a third hinge shaft.

[0014] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0015] 1) By using a special lifting tool for material cakes, multiple material cakes can be transported simultaneously, which not only improves the handling efficiency but also reduces the labor intensity of the operators.

[0016] 2) An elongated groove is provided at the hinge of the connecting rod to ensure that the spreader can provide a precise opening stroke for the clamping block when under load. This allows the clamping block to reliably clamp the bottom of the material cake, effectively preventing clamping failure due to insufficient or excessive stroke.

[0017] 3) With the support rod in place, the operator can engage it with the second connecting shaft and apply force to drive the movable rod back to the initial Y-shaped retracted state, so that the lifting device can be separated from the material cake.

[0018] 4) The limiting groove on the lifting device plays a limiting role when passing through the center hole of the material cake, ensuring that the lifting device is in precise positioning and can hook the bottom of the material cake, thus facilitating safe and stable lifting of materials.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 7 As shown in the figure, an embodiment of this utility model provides a special lifting device for material cakes, including: a lifting ring 1, at least one lifting device assembly 2, and a limiting groove 3. The top of the lifting device assembly 2 is connected to the lifting ring 1 via a first hinge shaft 4.

[0034] Each lifting assembly 2 includes two connecting rods 21 and a movable rod 22. The top ends of the two connecting rods 21 are hinged together by a first hinge shaft 4. The middle portions of the two movable rods 22 are hinged together by a third hinge shaft 6. The top end of each movable rod 22 is hinged to the bottom end of the corresponding connecting rod 21 by a second hinge shaft 5. A radially outwardly extending locking block 23 is provided at the bottom of each movable rod 22, and the two locking blocks 23 of the same lifting assembly 2 are arranged opposite to each other.

[0035] In the initial state, the lower ends of the two movable rods 22 are in a retracted state, making the two movable rods 22 form a Y-shaped structure. When the lifting device is under load, the movable rods 22 rotate around the third hinge axis 6, the lower ends of the two movable rods 22 open outward, and the upper ends retract inward simultaneously, thereby driving the locking block 23 to lock the bottom of the material cake.

[0036] Initially, the movable rod 22 retracts into a Y-shape, allowing the lifting device to be smoothly inserted into the center hole of the material cake. At the same time, the two locking blocks 23 are arranged opposite each other, so that when the lower end of the movable rod 22 opens outward, it can drive the locking blocks 23 to open outward from the inside, thereby locking the bottom of the material cake.

[0037] It should be noted that when there is only one lifting device assembly 2, in the initial state, the operator must manually retract its movable rod 22 into a Y-shaped structure in order to allow it to pass through the center hole of the cake and descend below the cake.

[0038] Each link 21 includes a straight rod portion 211 and a hinge portion 212. The straight rod portion 211 and the hinge portion 212 are arranged at an angle, and the included angle between the straight rod portion 211 and the hinge portion 212 is inward. An elongated groove 213 is provided on the hinge portion 212. In some embodiments, the included angle between the straight rod portion 211 and the hinge portion 212 is 100° to 160°. In this embodiment, the included angle between the straight rod portion 211 and the hinge portion 212 is 145°.

[0039] The top end of each movable rod 22 is connected to the bottom end of the corresponding connecting rod 21 via a second hinge shaft 5. The second hinge shaft 5 passes through an elongated groove 213 and can move axially along the elongated groove 213.

[0040] When the second hinge shaft 5 moves from the first end of the elongated groove 213 to the second end of the elongated groove 213, the locking block 23 opens and locks the bottom of the material cake.

[0041] In this embodiment, the end of the elongated groove 213 closest to the lifting ring 1 is defined as the first end, and the end furthest from the lifting ring 1 is positioned as the second end.

[0042] By setting the elongated groove 213, the clamping block 23 can be provided with an accurate opening stroke when the lifting device is under load, so that it can reliably clamp the bottom of the material cake, thereby effectively preventing clamping failure caused by insufficient or excessive stroke.

[0043] Furthermore, the movable rod 22 includes a connecting portion 221 and a clamping portion 222, which are arranged at an angle, with the included angle between the connecting portion 221 and the clamping portion 222 facing outwards. The top end of the connecting portion 221 is connected to the hinge portion 212 via a second hinge shaft 5, and its bottom end is hinged to the top of the clamping portion 222 via a third hinge shaft 6. A locking block 23 is disposed at the bottom of the clamping portion 222 and extends radially outwards.

[0044] In some embodiments, the included angle between the connecting portion 221 and the clamping portion 222 is 100° to 150°. In this embodiment, the included angle between the connecting portion 221 and the clamping portion 222 is 130°.

[0045] Given the large weight of the material cake, in this embodiment, the number of lifting device components 2 is set to two, thereby improving the overall load-bearing capacity and stability.

[0046] The two lifting assemblies 2 are a first lifting assembly and a second lifting assembly, respectively. The top ends of the two lifting assemblies 2 are hinged together by a first hinge shaft 4. The lifting ring 1 is sleeved on the outside of the first hinge shaft 4 and is located between the two lifting assemblies 2.

[0047] Furthermore, the connecting rod 21 of the first lifting device assembly, the movable rod 22 of the first lifting device assembly, the movable rod 22 of the second lifting device assembly, and the connecting rod 21 of the second lifting device assembly, all located on the same side, are hinged together by a second hinge shaft 5, and the second hinge shaft 5 passes through the elongated groove 213 at the bottom of the two connecting rods 21.

[0048] The middle portions of the two connecting rods 21 of the first lifting device assembly are respectively connected to the middle portions of the corresponding two connecting rods 21 in the second lifting device assembly via the first connecting shaft 7 and the second connecting shaft 8. The first end of the support rod 9 is connected to the first connecting shaft 7, and the second end of the support rod 9 is provided with a slot that can be engaged with the second connecting shaft 8.

[0049] To remove the lifting device, the operator engages the support rod 9 with the second connecting shaft 8 and applies force to return the movable rod 22 to its initial Y-shaped retractable structure, thereby separating the lifting device from the material cake.

[0050] The limiting groove 3 is provided with a clearance hole. The movable rod 22 passes through the clearance hole and is connected to the limiting groove 3 via the third hinge shaft 6. The two ends of the hinge shaft 6 are fixed to the two side walls of the limiting groove 3, respectively. The size of the clearance hole allows the movable rod 22 to swing within its maximum opening angle range.

[0051] The limiting groove 3 on the lifting device acts as a limit when passing through the center hole of the material cake, ensuring that the lifting device is in precise positioning and can hook the bottom of the material cake, thus facilitating safe and stable lifting of materials.

[0052] The working process of the special lifting device for material cakes is described below with reference to the attached diagram:

[0053] First, the lifting device is suspended from the overhead crane. The crane lowers the device through the center hole of the cake material until it is below the cake material, until the limiting groove 3 contacts the cake material. At this point, the slot of the support rod 9 is separated from the second connecting shaft 8. Then, the crane lifts the lifting device upwards, and the movable rod 22 rotates around the third hinge shaft 6, opening outwards at the lower end and retracting inwards at the upper end, causing the locking block 23 to clamp the bottom of the cake material. The crane then transfers the cake material to the cake material feed roller conveyor via the lifting device. After the cake material is in place, the operator engages the slot of the support rod 9 with the second connecting shaft 8 and presses it down, causing the movable rod 22 to return to its Y-shaped retracted state. Finally, the crane lifts the lifting device, completing one lifting operation.

[0054] By using a special lifting device for material cakes, operators are no longer required to move the cakes one by one, and multiple cakes can be moved at the same time, which not only improves the efficiency of handling, but also reduces the labor intensity of the operators.

[0055] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
