Description

Technical Field

[0001] The utility model belongs to the technical field of lifting tools, and particularly relates to a lifting tool for loading and unloading gears. Background Art

[0002] A lifting tool is a device used for lifting, transporting, and hoisting items. It realizes the functions of handling, transporting, or stacking through methods such as traction, suspension, consignment, lifting, or dumping. It can improve work efficiency, reduce labor costs, and ensure the safety of the lifting process.

[0003] Large or heavy gears are often heavy and large in volume. When loading and unloading large or heavy gears, manual handling is not only laborious but also prone to causing injury accidents. By using a lifting tool, this risk can be significantly reduced because it can use mechanical force to carry heavy objects, thereby reducing the physical burden of workers and the possibility of injury. Moreover, during the handling process, if manual operation is improper, the gear may be impacted or squeezed, resulting in damage. However, the existing lifting tools for gear loading and unloading cannot quickly clamp and fix or remove the gear. It is rather cumbersome when the lifting tool fixes or takes out the gear. The problem existing in the above technology is that the lifting tool cannot quickly clamp and fix or disassemble and remove the gear. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a lifting tool for loading and unloading gears that can overcome or at least partially solve the above problems.

[0005] The utility model is realized as follows. A lifting tool for loading and unloading gears includes a lifting tool and a workpiece. The lifting tool includes two hooks, a first connecting rod, two second connecting rods, two first lifting rods, a third connecting rod, and a second lifting rod. The workpiece is located at the bottom inside the two hooks. The tops inside the two hooks are both movably connected to the surface of the first connecting rod. The surfaces of the two second connecting rods are respectively movably connected to the tops inside the two hooks and the bottoms inside the two first lifting rods. The surfaces of the two first lifting rods are respectively attached to the surfaces of the two hooks. The tops inside the two first lifting rods and the bottom inside the second lifting rod are both movably connected to the surface of the third connecting rod;

[0006] The lifting tool is used for clamping the workpiece.

[0007] To enable the spreader to be used properly, preferably, opening pins are provided on both the front and rear sides inside the first connecting rod, the two second connecting rods, and the third connecting rod for connecting the cotter pins. By inserting the cotter pins into the opening pins of the first connecting rod, the two second connecting rods, and the third connecting rod, it is possible to prevent the two hooks, the two first suspension rods, and the second suspension rod from detaching from the first connecting rod, the two second connecting rods, and the third connecting rod.

[0008] To make the spreader move more stably after clamping the workpiece, preferably, a stop block is sleeved on the surface of the third connecting rod. The side of the stop block close to the second suspension rod is in contact with the second suspension rod. The stop block plays a limiting role to prevent the second suspension rod from swaying back and forth on the surface of the third connecting rod during use.

[0009] To facilitate the disassembly and assembly of the various components of the spreader, preferably, the first connecting rod, the two second connecting rods, and the third connecting rod have the same shape. Since the first connecting rod, the two second connecting rods, and the third connecting rod have the same shape, there is no need to find corresponding installation steps for connecting rods of different shapes, making the installation simpler. There is no need to distinguish between connecting rods of different shapes, thus saving disassembly time and labor costs.

[0010] The present utility model is provided with structural components such as a spreader, hooks, a first connecting rod, and a second connecting rod. The spreader can quickly clamp and fix the workpiece and is convenient for removing the workpiece. Through multiple opening pins, the spreader can normally clamp the workpiece to prevent the two hooks, the two first suspension rods, and the second suspension rod from detaching. The stop block can play a limiting role on the second suspension rod to prevent the second suspension rod from being misaligned in the front and rear directions during use, making the use more stable, achieving the effect of quickly clamping and fixing or removing the workpiece.

[0018] In order to further understand the inventive content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0019] The structure of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0020] As Figures 1 to 6 shown, a hoisting tool for gear loading and unloading provided by an embodiment of the present utility model includes a hoisting tool 1 and a workpiece 2. The hoisting tool 1 includes two hooks 101, a first connecting rod 102, two second connecting rods 103, two first suspension rods 104, a third connecting rod 105 and a second suspension rod 106. The workpiece 2 is located at the bottom inside the two hooks 101. The tops inside the two hooks 101 are movably connected to the surface of the first connecting rod 102. The surfaces of the two second connecting rods 103 are respectively movably connected to the tops inside the two hooks 101 and the bottoms inside the two first suspension rods 104. The surfaces of the two first suspension rods 104 are respectively attached to the surfaces of the two hooks 101. The tops inside the two first suspension rods 104 and the bottom inside the second suspension rod 106 are both movably connected to the surface of the third connecting rod 105. The hoisting tool 1 is used to clamp the workpiece 2. In order to enable the hoisting tool 1 to be used normally, split pins 3 are provided on the front and rear sides inside the first connecting rod 102, the two second connecting rods 103 and the third connecting rod 105 for connecting the split pins. By inserting the split pins 3 of the first connecting rod 102, the two second connecting rods 103 and the third connecting rod 105, it is possible to prevent the two hooks 101, the two first suspension rods 104 and the second suspension rod 106 from detaching from the first connecting rod 102, the two second connecting rods 103 and the third connecting rod 105. In order to make the hoisting tool 1 move more stably after clamping the workpiece 2, a stopper 4 is sleeved on the surface of the third connecting rod 105. The side of the stopper 4 close to the second suspension rod 106 is attached to the second suspension rod 106. Through the stopper 4, a limiting function is achieved to prevent the second suspension rod 106 from shaking back and forth on the surface of the third connecting rod 105 during use. In order to facilitate the disassembly and assembly of the various components of the hoisting tool 1, the first connecting rod 102, the two second connecting rods 103 and the third connecting rod 105 have the same shape. By having the same shape of the first connecting rod 102, the two second connecting rods 103 and the third connecting rod 105, there is no need to find corresponding installation steps for connecting rods of different shapes, making the installation simpler. There is no need to distinguish between connecting rods of different shapes, thus saving disassembly time and labor costs.

[0021] When it is necessary to clamp the workpiece 2, by moving the two hooks 101 to the position of the workpiece 2 and moving the second suspension rod 106 upward, when the second suspension rod 106 moves upward, it will cause the two first suspension rods 104 to move upward through the third connecting rod 105. During the upward movement of the two first suspension rods 104, they will cause the two hooks 101 to move upward through the two second connecting rods 103. During the upward movement of the two hooks 101, the tops of the two hooks 101 will rotate towards the opposite ends through the first connecting rod 102, so that the bottoms of the two hooks 101 clamp and fix the workpiece 2, realizing that the two hooks 101 clamp and fix the workpiece 2 all the time during the process of driving the workpiece 2 to transfer.
