Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting, and particularly relates to a double clamp hoisting tool. Background Art

[0002] A clamp hoisting tool is a device used for hoisting and transporting heavy objects. It usually consists of two or more adjustable clamps, which are used to grip different parts of the hoisted object, so as to carry out hoisting operations evenly and safely. This kind of tool is mainly applied to hoisting scenarios that require precise control and stable support, such as mechanical equipment installation, building material handling, etc.

[0003] Single-point hoisting in the prior art refers to connecting and hoisting an object through a single point, usually by using a single connection point such as a hook or a lifting ring to lift the object. Although single-point hoisting is simple and effective in some cases, it also has some obvious disadvantages:

[0004] 1. Unbalanced load: Single-point hoisting often leads to unbalanced load on the object. Especially in the case of large or asymmetrical objects, it will cause the object to rotate or tilt, increasing the risk of accidents.

[0005] 2. Limited to the center-of-gravity position: The center of gravity of the hoisted object must be accurately located directly above the hoisting point. Otherwise, it will cause the object to tilt or be in an unstable state, requiring additional adjustment and control.

[0006] 3. Inapplicable to some objects: Some objects with complex shapes or uneven surfaces are not suitable for single-point hoisting because it is impossible to ensure uniform and safe lifting and handling.

[0007] 4. Risks of safety and stability: The stability of single-point hoisting is poor and it is easily affected by external forces and environmental conditions, such as wind force, swinging, etc., which may cause accidents.

[0008] In summary, although single-point hoisting is still applicable in some light or simple hoisting tasks, in heavy and complex hoisting tasks, the clamp hoisting tool can provide a safer and more reliable solution through multi-point clamping and more stable support. Summary of the Utility Model

[0009] The purpose of the utility model is to provide a double clamp hoisting tool to solve the problems existing in the prior art.

[0010] To achieve the above object, the technical solution adopted by the present utility model is a double-grip hoisting tool, including a hanging plate, a hanging hole is provided on the hanging plate, two vertically arranged connecting plates are symmetrically arranged below the hanging plate, and a first pulling plate and a second pulling plate are respectively connected to the lower parts of the two connecting plates through hinge shafts. A first connecting arm is connected to the lower part of the first pulling plate through a hinge shaft, and a second connecting arm is connected to the lower part of the second pulling plate through a hinge shaft. One end of the first connecting arm away from the first pulling plate is connected to a first clamping plate, and one end of the second connecting arm away from the second pulling plate is connected to a second clamping plate. The first clamping plate and the second clamping plate are connected through a hinge shaft. A first clamping head is provided at one end of the first clamping plate away from the first connecting arm, and a second clamping head is provided at one end of the second clamping plate away from the second connecting arm. A bearing plate is arranged on one side of the first clamping plate, and pressing heads are symmetrically arranged on the bearing plate. The pressing heads are inclined, and a contact spring is arranged at one end of the pressing head away from the bearing plate.

[0011] Preferably, the first clamping head and the second clamping head are steel pipes, and the ends of the first clamping head and the second clamping head away from the first clamping plate and the second clamping plate are conical.

[0012] Preferably, the pressing head is in an inverted L shape.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] In this embodiment, as Figure 1-2As shown in the figure, the specific design of the above key components is described below: A double-clamp hoisting tool includes a suspension plate 1, on which a suspension hole 2 is provided. Symmetrically arranged below the suspension plate 1 are two vertically arranged connecting plates 3. Below both connecting plates 3, a first pulling plate 4 and a second pulling plate 5 are connected through hinge shafts. Below the first pulling plate 4, a first connecting arm 7 is connected through a hinge shaft. Below the second pulling plate 5, a second connecting arm is connected through a hinge shaft. One end of the first connecting arm 7 away from the first pulling plate 4 is connected to a first clamping plate 8. One end of the second connecting arm away from the second pulling plate 5 is connected to a second clamping plate 9. The first clamping plate 8 and the second clamping plate 9 are connected through a hinge shaft. At one end of the first clamping plate 8 away from the first connecting arm 7, a first clamping head 10 is provided. At one end of the second clamping plate 9 away from the second connecting arm, a second clamping head 11 is provided. On the side of the first clamping plate 8, a bearing plate 12 is provided. Symmetrically arranged on the bearing plate 12 are pressing heads 13, which are inclined. At one end of the pressing head 13 away from the bearing plate 12, a contact spring 14 is provided. The object is clamped within the first clamping head 10 and the second clamping head 11 by the conical tips of the first clamping head 10 and the second clamping head 11. The suspension hole 2 is connected to a lifting device. The first pulling plate 4 and the second pulling plate 5 become straight and vertical states. The plate distance spring 17 provides a shock-absorbing effect to avoid damaging the object due to excessive clamping force. The first pulling plate 4 pulls the first connecting arm 7, the first connecting arm 7 pulls the first clamping plate 8, and the first pulling plate 4 then pulls the first clamping head 10. The second pulling plate 5 pulls the second connecting arm, the second connecting arm pulls the second clamping plate 9, and the second pulling plate 5 then pulls the second clamping head 11. The clamping action is realized through the hinge shaft. Additionally, the pressing head 13 can press the hoisted object and adapt to different pressing degrees of the object through the contact spring 14 to avoid the shaking during hoisting. Through the two vertically arranged connecting plates 3 and the corresponding pulling plates, connecting arms, and clamping plates, multi-point support and clamping of the hoisted object can be achieved. This multi-point clamping method helps to evenly distribute the weight, improving the stability and safety of the hoisted object. The design of the hinge shaft enables the adjustment of angles and positions between the connecting plates 3, pulling plates, connecting arms, and clamping plates to adapt to hoisted objects of different shapes and sizes. This adjustability can provide more precise clamping and support, reducing the problem of unstable hoisting caused by irregular shapes. The pressing head 13 is inclined, and a contact spring 14 is provided at one end away from the bearing plate 12. Such a design can provide additional pressure and stability when clamping the clamping heads, further improving the safety and reliability of the hoisting operation, significantly enhancing the safety, stability, and efficiency of the hoisting operation, and being applicable to various hoisting tasks that require precise control and stable support.

[0026] In order to further improve the clamping force and effect on the clamped object, chuck one 10 and chuck two 11 are steel pipes. The ends of chuck one 10 and chuck two 11 away from clamping plate one 8 and clamping plate two 9 are conical. The pressure head 13 is in an inverted L shape. A plate distance spring 17 is arranged between connecting arm one 7 and connecting arm two. A lower pressing plate 15 is arranged on the side of pull plate two 5. An upper pushing plate 16 is arranged on the side of connecting arm two. The lower pressing plate 15 and the upper pushing plate 16 are staggeredly distributed. Connecting arm one 7 and clamping plate one 8 are integrally welded. Connecting arm two and clamping plate two 9 are integrally welded. The ends of chuck one 10 and chuck two 11 away from clamping plate one 8 and clamping plate two 9 are conical. This facilitates the object to enter the clamping range of chuck one 10 and chuck two 11, and the conical structure can just form a further deep bend with the chuck, clamping the target object more tightly, enhancing the stability and safety of clamping. The pressure head 13 is in an inverted L shape. When the pressure head 13 contacts the object to be clamped, it can provide a more uniform pressure distribution and a more stable clamping effect, which helps to ensure that the object being lifted does not move or shake during transportation and suspension. A plate distance spring 17 is arranged between connecting arm one and connecting arm two, which can provide appropriate elasticity during clamping to ensure that the clamping force is appropriate and stable, helping to avoid problems caused by excessive or insufficient clamping force, and improving the operation accuracy and safety. A lower pressing plate 15 is arranged on the side of pull plate two 5, and an upper pushing plate 16 is arranged on the side of connecting arm two, and they are staggeredly distributed. This design provides convenience when opening chuck one 10 and chuck two 11 for loading and unloading objects. The plate distance spring 17 can be compressed by manually pressing down the lower pressing plate 15 and the upper pushing plate 16 to further open chuck one 10 and chuck two 11, which is similar to scissors. The staggered arrangement avoids forceful collision. Connecting arm one 7 and clamping plate one 8, connecting arm two and clamping plate two 9 are integrally welded. This connection method is more firm and stable than bolt or other fixing methods, which not only increases the strength of the overall structure but also reduces the risk of loosening or moving, improving the durability and long-term stability of the tool, making connecting arm one 7 move in unison with clamping plate one 8 and connecting arm two move in unison with clamping plate two 9, facilitating clamping. Such a design significantly improves the clamping efficiency, operation safety and structural stability of the double-grip lifting tool, and is applicable to application scenarios with high requirements for lifting accuracy and safety.
