Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a lifting tool for aluminum profile processing. Background Technique

[0002] A lifting tool refers to a device for lifting heavy objects in a hoisting machine. The most commonly used lifting tools for lifting finished items are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forklift tines, etc. They are widely used in the hoisting and lifting industry. Commonly used in lifting tools are special rigging such as hooks, steel wires, and chains. Lifting suction cups, clamps, and forklift tines, etc. can be used as special lifting tools on a crane for a long time, or can be used as replaceable auxiliary lifting tools hanging on the hook for temporary use, and are commonly used in multi-cargo type warehouses and yards to improve operation efficiency. The structural forms and sizes of aluminum profiles are various. When facing the processing operation of larger and heavier aluminum profiles, it is usually necessary to use a hoisting device in cooperation with a lifting tool to lift it to a designated position for convenient processing operations.

[0003] When hoisting large aluminum profiles, they are usually tied and lifted with a chain, or a lifting ring is set on the aluminum profile to facilitate the fixed connection of the sling. After processing, the lifting ring can be cut off. However, the above measures are all more cumbersome and time-consuming in implementation. Therefore, in view of the above problems, a lifting tool for aluminum profile processing is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a lifting tool for aluminum profile processing. The lifting tool realizes the clamping and fixing of the aluminum profile through the combined work between the fixed C-shaped part and the movable C-shaped part. The operation is simple and easy. And the movable C-shaped part can slide inside and outside the fixed C-shaped part, so that the clamping effect on aluminum profiles of different sizes within a certain range can be realized. At the same time, the position of the movable lifting part can also be adjusted, thereby changing the position of the lifting point, avoiding the situation that the profile deflects due to a large distance between the lifting point and the center of gravity when the fixture and the profile are lifted, and solving the technical problem that it is difficult for the lifting tool in the prior art to be efficiently connected with profiles of different sizes to improve the lifting work efficiency.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A lifting tool for aluminum profile processing includes a fixed C-shaped part, on which a convex chute is opened; a movable C-shaped part, which is slidably arranged in the convex chute; a movable lifting part, which is slidably sleeved on the fixed C-shaped part and is used for connecting with a sling; a tensioning screw rod, which is fixedly connected to the movable C-shaped part and passes through the fixed C-shaped part, and a fastening nut is threadedly connected to its end; and an anti-detachment fastener, which is arranged on the fixed C-shaped part.

[0007] Through the above structural form, the clamping and fixing of the aluminum profile is realized by the combined work between the fixed C-shaped part and the movable C-shaped part, and the combined action of the tension screw and the fastening nut is utilized to ensure the continuity of the clamping force. This operation is simple and easy to implement, and the movable C-shaped part can slide inside and outside the fixed C-shaped part, enabling the clamping of aluminum profiles with different sizes within a certain range; at the same time, the position of the movable hanging part can be adjusted, thereby changing the position of the hanging point and avoiding the situation where the profile deflects due to a large distance between the hanging point and the center of gravity when the fixture and the profile are lifted; and the provided anti-loosening fastener can improve its anti-loosening ability by pressing the fastening nut tightly.

[0008] In a possible implementation manner, the movable hanging part includes a rectangular frame slidably sleeved on the fixed C-shaped part, and a lifting connection block is fixedly arranged on the rectangular frame, and a through hole is opened on the lifting connection block.

[0009] Through the above structural form, the sliding connection between the whole movable hanging part and the fixed C-shaped part can be realized by the rectangular frame, and the lifting connection block provides a necessary structural basis for the fixed connection of the sling.

[0010] In a possible implementation manner, threaded through holes are opened on both sides of the rectangular frame, and locking bolts are threadedly connected in the threaded through holes.

[0011] Through the above structural form, after the position of the rectangular frame is adjusted, when the locking bolt is tightened, its end will be in close contact with the outer wall of the fixed C-shaped part and generate a large frictional force, playing a role in fixing the position of the rectangular frame.

[0012] In a possible implementation manner, the anti-loosening fastener includes an anti-loosening screw rotatably connected to the fixed C-shaped part, a clamping strip is threadedly connected to the anti-loosening screw, and a tightening wheel is fixedly connected to the outer end of the anti-loosening screw.

[0013] Through the above structural form, when the anti-loosening screw is rotated by the tightening wheel, due to the meshing action of the threads, the clamping strip will move downward to press the fastening nuts on both sides, thereby improving the anti-loosening ability of the fastening nuts.

[0014] In a possible implementation manner, buckle interfaces are opened at both ends of the clamping strip, and the opening positions of the two buckle interfaces are centrosymmetric about the center point of the clamping strip.

[0015] Through the above structural form, when the clamping strip rotates in one direction, its two ends can be far away from the fastening nuts, thereby avoiding interfering with the operation of workers during the installation and disassembly operations of the fastening nuts.

[0016] In a possible implementation, an anti-slip wing plate is fixedly connected to a position near the inner side of the movable C-shaped member. The anti-slip wing plate is slidably arranged in a convex chute and is in close contact with the chute wall of the convex chute.

[0017] With the above structural form, due to the setting of the anti-slip wing plate, the movable C-shaped member can only slide horizontally away from the fixed C-shaped member, preventing it from sliding vertically away from the fixed C-shaped member and affecting normal use.

[0018] In a possible implementation, a widening strip is fixedly arranged on the movable C-shaped member, and a cushion plate made of rubber material is pasted on the inner wall of the movable C-shaped member and the widening strip.

[0019] With the above structural form, the laying size of the cushion plate can be increased by the widening strip, and the friction force with the aluminum profile can be increased by the larger-sized cushion plate, thereby improving the clamping and fixing effect on the aluminum profile.

[0020] In a possible implementation, a number of anti-slip stripes are formed on the outer surface of the cushion plate. The anti-slip stripes are vertically arranged and their cross-sectional form is semi-circular.

[0021] With the above structural form, the friction force between the fixture and the aluminum profile can be further increased, improving the clamping and fixing effect.

[0022] In summary, the present utility model has the following beneficial technical effects:

[0023] The clamping and fixing of the aluminum profile are realized by the combined work between the fixed C-shaped member and the movable C-shaped member, and the combined action of the tension screw and the fastening nut is utilized to ensure the continuity of the clamping force. This operation is simple and easy, and the movable C-shaped member can slide in and out relative to the fixed C-shaped member, enabling the clamping of aluminum profiles with different sizes within a certain range;

[0024] At the same time, the position of the movable hanging member can be adjusted, thereby changing the hanging point position, avoiding the situation that the profile deflects due to a large distance between the hanging point and the center of gravity when the fixture and the profile are lifted, and the anti-loosening fastener can improve its anti-loosening ability by pressing the fastening nut tightly.

[0031] The technical solutions in the embodiments of this application are to solve the problems in the above - mentioned background technology, and the general idea is as follows:

[0032] As Figure 1 - Figure 2 shown, a lifting tool for aluminum profile processing provided in this embodiment includes a fixed C - shaped part 1 with a convex chute 11 opened thereon, a movable C - shaped part 2 slidably disposed in the convex chute 11, and a tensioning screw 4 fixedly connected to the movable C - shaped part 2 and passing through the fixed C - shaped part 1, and a tightening nut 41 is threadedly connected to the end thereof. Through the above - mentioned structural form, the clamping and fixing of the aluminum profile are realized by the combined work between the fixed C - shaped part 1 and the movable C - shaped part 2, and the combined action of the tensioning screw 4 and the tightening nut 41 is used to ensure the persistence of the clamping force. This operation is simple and easy to perform, and the movable C - shaped part 2 can slide in and out relative to the fixed C - shaped part 1, so that the clamping of aluminum profiles with different sizes within a certain range can be realized.

[0033] In addition, a lifting tool for aluminum profile processing provided in this embodiment further includes a movable hanging part 3 slidably sleeved on the fixed C - shaped part 1 for connecting with a sling, and an anti - detachment fastener 5 disposed on the fixed C - shaped part 1. Since the position of the movable hanging part 3 can be adjusted, the position of the lifting point can be changed, avoiding the situation that the profile deflects due to a large distance between the lifting point and the center of gravity when the fixture and the profile are lifted. The provided anti - detachment fastener 5 can improve its anti - loosening ability by pressing the tightening nut 41.

[0034] As Figure 1As shown in the figure, the movable suspension member 3 includes a rectangular frame 31 slidably sleeved on the fixed C-shaped member 1. A lifting connection block 32 is fixedly arranged on the rectangular frame 31, and a through hole is formed in the lifting connection block 32. Through the above structural form, the overall sliding connection between the movable suspension member 3 and the fixed C-shaped member 1 can be realized by the rectangular frame 31, and the lifting connection block 32 provides a necessary structural basis for the fixed connection of the sling. In addition, threaded holes are formed through both sides of the rectangular frame 31, and locking bolts 33 are threadedly connected in the threaded holes. When the position adjustment of the rectangular frame 31 is completed, the locking bolts 33 are tightened, and their ends will be in close contact with the outer wall of the fixed C-shaped member 1 and generate a large frictional force, playing a role in fixing the position of the rectangular frame 31.

[0035] As Figure 4 shown in the figure, the anti-detachment fastener 5 includes an anti-detachment screw rod 51 rotatably connected to the fixed C-shaped member 1. A clamping strip plate 52 is threadedly connected to the anti-detachment screw rod 51, and a tightening wheel 54 is fixedly connected to the outer end of the anti-detachment screw rod 51. Through the above structural form, when the anti-detachment screw rod 51 is screwed by the tightening wheel 54, due to the meshing of the threads, the clamping strip plate 52 will move downward to press the fastening nuts 41 on both sides, thereby improving the anti-loosening ability of the fastening nuts 41.

[0036] In addition, clamping interfaces 53 are formed at both ends of the clamping strip plate 52, and the opening positions of the two clamping interfaces 53 are centrosymmetric about the center point of the clamping strip plate 52. Through the above structural form, when the clamping strip plate 52 rotates in one direction, its two ends can be far away from the fastening nuts 41, thereby avoiding interference with the operation of workers during the installation and disassembly operations of the fastening nuts 41.

[0037] As Figure 2 shown in the figure, an anti-slip and anti-detachment wing plate 21 is fixedly connected to the position of the movable C-shaped member 2 close to the inner side. The anti-slip and anti-detachment wing plate 21 is slidably arranged in the convex chute 11 and is in close contact with the chute wall of the convex chute 11. Through the above structural form, due to the setting of the anti-slip and anti-detachment wing plate 21, the movable C-shaped member 2 can only slide horizontally away from the fixed C-shaped member 1, avoiding its sliding away from the fixed C-shaped member 1 in the vertical direction and affecting normal use.

[0038] As Figure 3As shown in the figure, a widening strip 22 is fixedly arranged on the movable C-shaped member 2. A backing plate 23 made of rubber material is pasted on the inner wall of the movable C-shaped member 2 and the widening strip 22. Through the above structural form, the laying size of the backing plate 23 can be increased by the widening strip 22, and the friction force with the aluminum profile can be increased by the backing plate 23 with a larger size, thereby improving the clamping and fixing effect on the aluminum profile. In particular, a number of anti-slip stripes 231 are formed on the outer surface of the backing plate 23. The anti-slip stripes 231 are arranged vertically and their cross-sectional form is semi-circular. This structural form can further increase the friction force between the fixture and the aluminum profile and improve the clamping and fixing effect.

[0039] The working principle and process of the present utility model:

[0040] The clamping and fixing of the aluminum profile is realized by the combined work between the fixed C-shaped member 1 and the movable C-shaped member 2, and the combined action of the tension screw 4 and the fastening nut 41 is utilized to ensure the existence of the clamping force. This operation is simple and easy to perform, and the movable C-shaped member 2 can slide inside and outside the fixed C-shaped member 1, so that the clamping of aluminum profiles with different sizes within a certain range can be realized, and it has strong applicability.

[0041] In addition, the main structure of the movable hanging member 3 is a rectangular frame 31. Since the position of the rectangular frame 31 can be adjusted, the position of the hanging point can be changed, avoiding the situation that the profile deflects due to a large distance between the hanging point and the center of gravity when the fixture and the profile are lifted. And when the position adjustment of the rectangular frame 31 is completed, the locking bolt 33 is tightened, and its end will be in close contact with the outer wall of the fixed C-shaped member 1 and generate a large friction force, playing a role in fixing the position of the rectangular frame 31.

[0042] Finally, the provided anti-loosening fastener 5 can improve its anti-loosening ability by pressing the fastening nut 41. Specifically, when the anti-loosening screw 51 is screwed by the tightening wheel 54, due to the meshing action of the threads, the clamping strip 52 will move downward to press the fastening nuts 41 on both sides, thereby improving the anti-loosening ability of the fastening nut 41.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
