Description

Technical Field

[0001] This application relates to the field of wire reel transportation technology, and in particular to a gripper mechanism for rapid loading and unloading of wire reels. Background Technology

[0002] Wire reels are widely used in industrial production, especially in industries such as cables and textiles, for storing and transporting rolled materials. With the rapid development of automated production and logistics systems, efficient and stable wire reel loading and unloading methods have become one of the key aspects of improving work efficiency.

[0003] The current method for handling cable reels mainly involves using a conveyor belt with tripods at both ends. Since the reel is I-shaped, after placing it on the belt, the crane hooks simultaneously engage the two tripods for hoisting. This method requires workers to first lay the belt flat, then push the reel so that the grooved part of the I-shaped reel is caught by the belt before continuing hoisting, making the operation rather cumbersome. Utility Model Content

[0004] This application provides a gripper mechanism for quick loading and unloading of wire reels, which solves the problem of cumbersome operation caused by the current method of transporting wire reels by belt.

[0005] A gripper mechanism for quick loading and unloading of wire reels includes:

[0006] The gripper assembly has two grippers, each hooking onto one end of the spool.

[0007] A lifting assembly is fixed to the two gripper assemblies, and the lifting assembly is capable of lifting the gripper assemblies and the reel.

[0008] By adopting the above technical solution, two gripper assemblies are set up to hook onto the two ends of the wire reel, and then a lifting assembly is used to lift the gripper assemblies and the wire reel, enabling rapid loading and unloading of the wire reel. This design makes the wire reel more stable during loading and unloading, reduces the complexity and time cost of manual operation, improves work efficiency, and makes the gripper mechanism applicable to various types and specifications of wire reels.

[0009] In one embodiment, each of the gripper assemblies includes a main hook and an auxiliary hook, the upper end of the main hook being connected to the lifting assembly, the auxiliary hook being fitted over the main hook, and both the main hook and the auxiliary hook being capable of hooking the reel.

[0010] By adopting the above technical solution, the lifting component moves upward to drive the main hook to hook the edge of the reel. Compared with the traditional method of using a belt to hold the reel, the operation is simpler and more direct. Workers only need to control the lifting and lowering of the lifting component to lift the reel, reducing labor intensity and operational difficulty. When the main hook accidentally disengages, the lower end of the auxiliary hook can hook the reel in time to prevent it from falling, thus avoiding equipment damage and personal injury accidents caused by the reel falling.

[0011] In one embodiment, both the main hook and the auxiliary hook are C-shaped. The auxiliary hook has a receiving hole, the main hook is disposed in the receiving hole and hinged to the auxiliary hook, both ends of the main hook protrude from the receiving hole, and the lower end of the main hook abuts against the upper end of the auxiliary hook.

[0012] By adopting the above technical solution, by controlling the upper end of the main hook to move downward, the lower end of the main hook can move clockwise towards the receiving hole, thereby forming a gap between the main hook and the auxiliary hook, which makes it easy for the main hook to hook the edge of the spool, and the upper end of the auxiliary hook can prevent the edge of the spool from detaching.

[0013] In one embodiment, the quick loading and unloading gripper mechanism for the spool further includes a movable component that controls the lower end of the main hook and the upper end of the auxiliary hook to clamp the spool.

[0014] By adopting the above technical solution, the movable component can precisely control the clamping of the spool between the lower end of the main hook and the upper end of the auxiliary hook. Through the action of the movable component, the clamping force between the main hook and the auxiliary hook can be adjusted according to the different thicknesses and sizes of the spool, ensuring that the spool will not loosen or fall off during hoisting.

[0015] In one embodiment, the movable element is an elastic element, which is disposed in the receiving hole and its two ends respectively abut against the upper end of the main hook and the upper end of the auxiliary hook.

[0016] By adopting the above technical solution, under normal circumstances, the lower end of the main hook abuts against the upper end of the auxiliary hook, and the elastic element is in a normal state. When it is necessary to clamp the coil, the upper end of the main hook is controlled to move downwards towards the upper end of the auxiliary hook, causing the elastic element to be compressed, and a gap is formed between the lower end of the main hook and the upper end of the auxiliary hook to facilitate clamping the coil. After the force is no longer applied, due to this gap, the elastic element still has some difficulty in extending and returning to its original position, thus applying a downward force to the upper end of the auxiliary hook, allowing the auxiliary hook to abut against the coil and preventing it from disengaging.

[0017] In one embodiment, the lifting assembly includes a chain and a lifting ring, the chain having two links, one end of each chain being fixed to the corresponding body hook, and the other end of each chain being fixed to the lifting ring.

[0018] By adopting the above technical solution, the lifting assembly uses two chains, each fixed to the main hook of one of the two gripper assemblies, and the other end of the chains is fixed to the lifting ring. This design ensures that the two ends of the reel remain balanced during lifting, preventing tilting and avoiding the risk of falling due to reel tilting, thus guaranteeing the safety of the lifting process.

[0019] In one embodiment, the lifting assembly further includes a lifting hook, the lifting ring being fitted with the lifting hook, and the lifting hook being capable of moving the lifting ring.

[0020] By adopting the above technical solution, the cooperation between the lifting hook and the lifting ring allows the gripper mechanism to be flexibly connected to external lifting equipment. The lifting hook can drive the lifting ring to move, thereby realizing the lifting of the wire reel. This connection method is simple to operate, convenient and quick, and can adapt to different lifting scenarios and requirements.

[0021] In one embodiment, the lifting hook is provided with a blocking member located in the opening of the lifting hook.

[0022] By adopting the above technical solution, a blocking component is installed at the opening of the lifting hook, which can effectively prevent the lifting ring from falling off the opening of the lifting hook. During the lifting process, even if there is shaking or vibration, the blocking component can prevent the lifting ring from detaching from the lifting hook, further improving the safety and reliability of the lifting process.

[0023] In summary, this application includes at least one beneficial effect:

[0024] 1. By setting two gripper assemblies to hook onto the two ends of the wire reel, and then using a lifting assembly to lift the gripper assemblies and the wire reel, rapid loading and unloading of the wire reel can be achieved. This design makes the wire reel more stable during loading and unloading, reduces the complexity and time cost of manual operation, improves work efficiency, and makes this gripper mechanism applicable to various types and specifications of wire reels.

[0025] 2. Under normal circumstances, the lower end of the main hook abuts against the upper end of the auxiliary hook, and the elastic element is in its normal state. When it is necessary to clamp the coil, the upper end of the main hook is moved downwards towards the upper end of the auxiliary hook, compressing the elastic element and creating a gap between the lower end of the main hook and the upper end of the auxiliary hook to facilitate clamping the coil. After the force is removed, due to this gap, the elastic element still has some difficulty in extending and returning to its original position, thus applying a downward force to the upper end of the auxiliary hook, allowing the auxiliary hook to abut against the coil and preventing it from disengaging.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-4 The clamping mechanism for rapid loading and unloading of wire reels provided in this application will be described in further detail.

[0032] Example 1

[0033] Please see Figure 1-4 The present application provides a clamping mechanism 1 for quick loading and unloading of wire reels, which includes two parts: a clamping assembly 11 and a lifting assembly 12.

[0034] like Figures 1 to 2 As shown, the gripper assembly 11 has two grippers, each hooking onto both ends of the wire reel. The lifting assembly 12 is fixedly connected to the two gripper assemblies 11 for overall lifting. Specifically, the wire reel is I-shaped, with outward-protruding edges at both ends to facilitate hooking by the gripper assemblies 11. The gripper assembly 11 consists of a main hook 111 and an auxiliary hook 112. The main hook 111 can be made of high-strength alloy steel, with a hardened surface to enhance wear resistance; the auxiliary hook 112 is preferably made of corrosion-resistant stainless steel, both possessing good mechanical properties. Both the main hook 111 and the auxiliary hook 112 are designed in a C-shape. The auxiliary hook 112 has a precision-machined receiving hole 1121 inside, into which the main hook 111 is embedded. The pin 113 passes through the auxiliary hook 112 and the main hook 111, making them hinged. Both ends of the main hook 111 protrude from the receiving hole 1121. The upper end of the main hook 111 is connected to the lifting assembly 12 and its width is greater than the width of the receiving hole 1121. The lower end of the main hook 111 abuts against the upper end of the auxiliary hook 112, ensuring that the two can work together and can flexibly adjust their posture under specific conditions.

[0035] like Figure 3As shown, furthermore, in order to ensure that the lower end of the main hook 111 and the upper end of the auxiliary hook 112 can clamp the edge of the spool and prevent the spool from falling off, a movable member 13 is arranged to adjust the positional relationship between the main hook 111 and the auxiliary hook 112. In this embodiment, the movable member 13 can be an elastic member 131, which is disposed in the receiving hole 1121. It is preferably in the form of a helical spring, including two springs, each fitted with a pin 113. The two springs are located at opposite ends of the main hook 111 and are connected to each other at the ends closer to the main hook 111. The ends of the two springs away from the main hook 111 abut against the upper end of the auxiliary hook 112, so that the two ends of the springs can abut against the main hook 111 and the auxiliary hook 112 respectively. When the spool is not needed to be lifted, the spring is in its natural state, causing the end of the main hook 111 to be tightly pressed against the upper end of the auxiliary hook 112 to form a closed locking state. Once an external force is applied to force the upper end of the main hook 111 downward, the spring will be compressed, thereby widening the opening distance between the lower end of the main hook 111 and the upper end of the auxiliary hook 112 to facilitate the insertion of the spool. After the external force is removed, although the spring returns to its original position, it is still compressed, thereby generating a reaction force against the upper end of the auxiliary hook 112, so that the auxiliary hook 112 can abut against the spool, making the spool firmly held at a certain height, thereby enabling the gripper assembly 11 to grip spools with different sized edges.

[0036] like Figure 4 As shown, the lifting assembly 12 mainly includes two chains 121 of equal length and a lifting ring 122 located at the top center. The lower end of each chain 121 is fixed to the top of its corresponding main hook 111 by bolts or rivets, while the upper ends of the chains 121 converge and are securely locked to the lifting ring 122. This design ensures that the weight is evenly distributed regardless of the size of the reel, effectively reducing the possibility of swaying and ultimately achieving stable and reliable transport. Furthermore, considering the environmental adaptability requirements under actual working conditions, it is recommended to use special alloy chains 121 with hot-dip galvanized surface treatment instead of traditional ordinary steel products to improve corrosion resistance and service life.

[0037] The lifting assembly 12 also includes a lifting hook 123, with a lifting ring 122 fitted onto the lifting hook 123 to facilitate lifting with the lifting hook 123 carrying the lifting ring 122. Specifically, the lifting hook 123 includes a blocking member 124, which is located at the opening of the lifting hook 123 to prevent the lifting ring 122 from detaching. In this embodiment, the blocking member 124 is a torsion spring, located at both ends of the lifting hook 123. The ends of the two torsion springs near the lifting hook 123 are connected to and fixed to the back of the lifting hook 123, while the ends away from the lifting hook 123 are connected to and abut against the inner side of the lifting hook 123 to block the opening of the lifting hook 123. This allows the torsion springs to move inward to open, facilitating the entry and fitting of the lifting ring 122 onto the lifting hook 123. However, when the torsion springs move outward, they will abut against the lifting hook 123, making it difficult to open and thus preventing the lifting ring 122 from detaching.

[0038] The implementation principle of this embodiment is as follows: the lower end of the main hook 111 hooks onto the edge of the spool, facilitating its lifting. Furthermore, when the lower end of the main hook 111 and the upper end of the auxiliary hook 112 are opened and the spool is placed, the elastic element 131 is compressed. Consequently, when the spool is lifted, the reaction force of the elastic element 131 abuts against the auxiliary hook 112, ensuring a tight fit against the spool. This ensures that the main hook 111 and the auxiliary hook 112 clamp the spool, preventing it from falling off. Even if the spool falls off the main hook 111, the lower end of the auxiliary hook 112 can still hook onto it, further preventing it from falling off.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
