Description

Technical Field

[0001] The utility model belongs to the technical field of slings, and in particular relates to a lever self-locking energy-saving adjustable clamping sling. Background Art

[0002] Hoisting tools are widely used in industries such as industry, construction, and transportation, primarily for lifting, transporting, and securing cargo. The production and processing of large-scale ceramic and composite materials often require lifting and transporting these materials. These tools typically utilize traditional, simple hoists, primarily using ropes or other binding mechanisms for lifting and transport.

[0003] Since the materials being hoisted are usually non-standard parts, general hoists need to be constantly adjusted during operation to ensure the tightness of clamping or bundling, which seriously affects transportation efficiency. In addition, such materials are usually large in size, smooth in surface and without lifting rings. When hoisted, they are tied with ropes or other means, which makes them easy to slip and fall during transportation, posing a huge safety hazard.

[0004] Chinese patent CN202123424109.2 discloses a novel adjustable billet hoist. This hoist features an adjustment mechanism that allows for flexible and stable adjustment of the distance between the left and right sets of movable plates, making the hoist suitable for billets of varying sizes. Furthermore, the hoist can quickly and automatically clamp and lift the billet by rotating the clamping components. However, the overall structure of this hoist is complex, requiring a motor to clamp the object being hoisted, which results in increasing energy consumption.

[0005] Chinese patent CN 208394627 U discloses an adjustable clamping spreader, which is provided with a stroke adjustment component to adjust the position of the vertical tension applied to the spreader, thereby distributing the friction force on both sides. However, the spreader is still unstable in the horizontal direction and prone to falling. Utility Model Content

[0006] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a lever self-locking energy-saving adjustable clamping sling to solve the technical problems of low clamping stability of traditional slings and high energy consumption caused by the need for motor drive.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The utility model discloses a lever self-locking energy-saving adjustable clamping sling, comprising: a tensioning ring, a boom, a balance adjustment assembly and a clamping assembly; the tensioning ring is arranged on the top of the boom, the balance adjustment assembly is connected to the bottom of the boom, and the clamping assembly is connected to the bottom of the balance adjustment assembly;

[0009] Furthermore, the clamping assembly includes: a clamping arm, a fixed clamping arm, a clamping block and a clamping plate; the clamping arm is movably connected to one end of the balance adjustment assembly, the fixed clamping arm is connected to the other end of the balance adjustment assembly, the clamping block is connected to the bottom end of the clamping arm, and the clamping plate is connected to the bottom end of the fixed clamping arm; when clamping an object, the clamping arm can drive the clamping block to swing toward the side of the clamped object.

[0010] Furthermore, the balance adjustment component includes a sleeved crossbeam and a length adjustment rod, the length adjustment rod can move horizontally in the crossbeam, a plurality of pin holes are opened on the length adjustment rod, and the pin holes are matched with adjustment pins for adjusting the horizontal translation distance of the length adjustment rod.

[0011] Furthermore, there are at least two pin holes, and the plurality of pin holes are opened at equal distances.

[0012] Furthermore, the pressing block is connected to the bottom end of the clamping arm via a fastening screw.

[0013] Furthermore, the adjustment range of the length adjustment rod is 700 mm to 1300 mm.

[0014] Furthermore, the clamping plate is equipped with an anti-skid plate.

[0015] Furthermore, the anti-slip plate is made of rubber.

[0016] Furthermore, the anti-slip plate is made of nitrile rubber.

[0017] Furthermore, the clamping plate is V-shaped.

[0018] Furthermore, the tensioning eye is connected to the top of the boom via a tightening screw.

[0019] Furthermore, the clamping plate and the pressing block are arranged facing each other.

[0020] Furthermore, the clamping arm is movably connected to one end of the balance adjustment component through a pin.

[0021] Furthermore, the clamping arm swings toward the clamped object at an angle of 0°-30°.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The key point of the utility model's lever-type self-locking energy-saving adjustable clamping sling is that it is provided with a clamping assembly consisting of a clamping arm, a fixed clamping arm, a clamping block, and a clamping plate, and a clamping block is connected to the bottom end of the clamping arm. The clamping arm is movably connected to one end of the balance adjustment assembly, and utilizes the lever principle and the synergistic effect between the clamping arm, the fixed clamping arm, the clamping block, and the clamping plate to enable the clamping arm to drive the clamping block to swing toward the side of the clamped object, and the gravity of the suspended object is fixed and compressed in the horizontal direction of the suspended object through the lever-type lifting arm. Compared with traditional fixing and compression methods, this invention simplifies the design of the sling, improves the clamping stability of the suspended object in the horizontal direction, and does not require other auxiliary equipment such as motors, thus saving energy.

[0024] Furthermore, the present invention also includes a balance adjustment assembly. By means of a sleeved crossbeam and length adjustment rod, the length adjustment rod can move horizontally within the crossbeam. The length adjustment rod is provided with a plurality of latch holes, which are matched with adjustment latches to adjust the horizontal translation distance of the length adjustment rod. In summary, the combination of the adjustment latches, crossbeam, length adjustment rod, and latch holes allows for coarse adjustment of the clamping position of the suspended object, achieving an adjustable clamping range.

[0025] Furthermore, an anti-slip plate is provided on the clamping plate of the present invention, which increases the friction between the clamping plate and the suspended object and ensures the stability of the clamping.

[0026] Furthermore, the present invention also sets the shape of the clamping plate to be V-shaped, which increases the contact area between the fixed clamping arm and the suspended object, ensuring the clamping stability while also preventing the suspended object from slipping.

[0027] Furthermore, the clamping arm of the present invention is movably connected to one end of the balance adjustment assembly via a pin. The clamping arm can swing around the pin toward the object being hoisted until a secure clamp is achieved, thus achieving a self-locking clamping function. This design allows the clamping assembly to exert a greater clamping force on the clamped object. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention is described in further detail below with reference to the accompanying drawings:

[0039] like Figure 1 As shown, the utility model discloses a lever self-locking energy-saving adjustable clamping sling, comprising: a tensioning ring 4, a boom 6, a balance adjustment assembly and a clamping assembly; the top of the boom 6 is provided with a tensioning ring 4, the bottom of which is connected to the balance adjustment assembly, and the clamping assembly is connected to the bottom of the balance adjustment assembly; the tensioning ring 4 can be connected to a lifting device;

[0040] The clamping assembly includes: a clamping arm 8, a fixed clamping arm 12, a pressure block 3, and a clamping plate 1. The clamping arm 8 is movably connected to one end of the balance adjustment assembly via a pin 7. During the lifting process of the lifting equipment, by applying an upward pulling force to the tensioning ring 4 and driving the lifting arm 6 upward, the clamping arm 8 uses the principle of leverage and the synergistic effect between the clamping arm 8, the fixed clamping arm 12, the pressure block 3, and the clamping plate 1 to swing toward the side of the suspended object. The pressure block 3 then applies horizontal pressure to the suspended object and transmits the horizontal force to the other side of the suspended object through the lever-type lifting arm, achieving a lever-type self-locking fixation and compression of the suspended object in the horizontal direction. The clamping arm 8 can swing toward the clamped object through an angle of 0°-30°. The fixed clamping arm 12 is connected to the other end of the balance adjustment assembly, the pressure block 3 is connected to the bottom end of the clamping arm 8, and the clamping plate 1 is connected to the bottom end of the fixed clamping arm 12.

[0041] The balance adjustment assembly includes an adjustment pin 2, a crossbeam 9, a length adjustment rod 10, and a pin hole 11. The length adjustment rod 10 is sleeved onto the crossbeam 9 and is provided with a pin hole 11. This pin hole 11 works in conjunction with the adjustment pin 2. By coordinating the adjustment pin 2, the crossbeam 9, the length adjustment rod 10, and the pin hole 11, the clamping force of the suspended object can be roughly adjusted, achieving adjustable clamping range. At least two pin holes 11 are provided, and they are spaced evenly apart. The adjustment range of the length adjustment rod 10 is 700 mm to 1300 mm.

[0042] like Figure 3 and Figure 4 As shown, the pressing block 3 is connected to the bottom end of the clamping arm 8 through a fastening screw 14, which can fix and press the suspended object in the horizontal direction.

[0043] like Figure 2 As shown, the clamping plate 1 is equipped with an anti-slip plate 13, which increases the friction between the clamping plate 1 and the suspended object, ensuring clamping stability. The clamping plate 1 is V-shaped, which increases the contact area between the fixed clamping arm 12 and the suspended object, ensuring clamping stability while also preventing the suspended object from slipping.

[0044] The utility model discloses a lever self-locking energy-saving adjustable clamping sling, which has an adjustable clamping range of 700mm to 1300mm during use. Specifically, it includes:

[0045] First, according to the size of the object to be hoisted, insert or pull out the length adjustment rod 10 from the beam 9, select the corresponding pin hole 11 and insert the adjustment pin 2. By selecting the appropriate pin hole 11 and fixing the adjustment pin 2, the object to be hoisted can be initially clamped.

[0046] As the lifting device ascends, the upward force tightens the lifting ring 4, driving the lifting arm 6 upward. The lifting arm 6, the pin 7, and the clamping arm 8 leverage each other to bring the clamping block 3 into close contact with one side of the object being hoisted. Specifically, as the clamping arm 8 swings toward the object as the lifting device ascends, the clamping block 3 applies horizontal pressure to the object and transmits this horizontal force to the other side, achieving self-locking, lever-type fixation and compression.

[0047] During the lifting process, the suspended object is further secured and compressed by the clamping plate 1 and the pressure block 3. The clamping plate 1 is welded to the fixed clamping arm 12. The design of the clamping plate 1 increases its contact area with the clamping arm 8 and the suspended object. Furthermore, the anti-slip plate 13 installed on the clamping plate 1 increases the friction between the clamping plate 1 and the suspended object, ensuring the clamping stability of the sling and improving its safety. The other side of the suspended object is clamped and fixed by the pressure block 3, which enhances the radial clamping force.

[0048] The above content is only for explaining the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the claims of the present invention.
