Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacking and handling equipment technology, and in particular to a rotatable mechanical hook. Background Technology
[0002] Products are stacked in frames. The production line transports the frames to the transfer platform of a planar transfer device, which then transfers and stacks the frames and their contents to the unloading area. The existing planar transfer device has mechanical hooks on both ends. These hooks only perform a single hooking action, and their large support components require significant space. After the frames are stacked in the designated area, the hooks need to be removed, resulting in a need for more working space between adjacent stacking areas. This leads to poor space utilization and a limited number of stacks. Utility Model Content
[0003] In order to overcome the technical defects mentioned in the background art, the purpose of this utility model is to provide a rotatable mechanical hook.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A rotatable mechanical hook includes a rotating rod, a fixed sleeve sequentially disposed at one end of the rotating rod, and a hook claw. The rotating rod includes a rod body and a connector. The fixed sleeve is fixedly connected to one end of the rod body, and the periphery of the fixed sleeve abuts against the product being hooked. One end of the hook claw is fixedly connected to one end of the rod body, and the other end of the hook claw protrudes from the fixed sleeve. The central axis of the fixed sleeve and the length direction of the hook claw are arranged in an L-shape. The connector is fixedly connected to the other end of the rod body. The connector is used to connect to an external driving device to drive the rod body, the fixed sleeve, and the hook claw to rotate by a set angle.
[0006] By adopting the above technical solution, the connector is connected to the external drive equipment, and the fixed sleeve and hook are fixed on the rotating rod. The periphery of the fixed sleeve abuts against the frame, which can limit the swaying amplitude of the frame during transportation, thereby improving the placement accuracy. The hook protrudes from the fixed sleeve to hook the frame. During the process of lowering the hook to pick up materials or removing the frame after stacking, the length direction of the hook is parallel to the length direction of the frame. When the hook is lowered to the set position, the external drive equipment drives the connector to rotate the fixed sleeve and hook together by a set angle through the rod body. After rotation, the hook is exactly in the hooking and fixing position of the frame, which makes reasonable use of space, reduces the required working space, makes the stacking area more dense, improves the space utilization efficiency and the number of stacks, and saves costs.
[0007] Furthermore, the distances from the periphery of the fixing sleeve to the center of the rod body are set differently. When the hook grabs the product, the distance between the periphery of the fixing sleeve and the product is minimized, which can further reduce the movable space of the frame, thereby reducing the amplitude of frame swaying and the distance of misalignment during transportation, and improving the stacking accuracy and efficiency.
[0008] Furthermore, the fixing sleeve is configured as a cylindrical structure, and the fixing sleeve is eccentrically positioned with respect to the rotating rod, resulting in a simple structure and low cost.
[0009] Furthermore, a first groove is provided at one end of the rotating rod along its length. The fixing sleeve has a through first fixing groove, and a second groove is provided on the wall of the first fixing groove corresponding to the position of the first groove. The end of the hook has a through second fixing groove, and one end of the rotating rod passes sequentially through the first fixing groove and the second fixing groove. A third groove is provided on the wall of the second fixing groove corresponding to the position of the first groove. The first groove, the second groove, and the third groove form a connected closed area. A flat key is provided within the closed area to allow the rotating rod, the fixing sleeve, and the hook to rotate synchronously, improving the overall stability of the linkage. The structure is simple and easy to install and disassemble.
[0010] Furthermore, the hook includes a square fixing part and a conical supporting part. The fixing part is connected to the rotating rod, and the supporting part is fixedly connected to the side of the fixing part. The side of the supporting part that contacts the product is set as a plane, and the other side of the supporting part is provided with a weight-reducing groove. The thickness of the supporting part decreases along the direction away from the rotating rod, which reduces cost, reduces the space occupied, and facilitates the alignment of the supporting part to the corresponding hooking position.
[0011] Furthermore, the rotatable mechanical hook also includes a mounting base. A bearing seat is located in the middle of the mounting base, and the other end of the rod body passes through the bearing seat and connects to the connector, facilitating easy installation and disassembly and improving rotational stability.
[0012] Furthermore, the fixing base includes a base plate, a mounting plate, two support plates, and two fixing plates. The base plate and the mounting plate are arranged parallel to each other at their top and bottom. Each of the mounting plates and the base plate has a support plate connected to its opposite sides, and the support plates are located on the side of the base plate where the fixing sleeve is located. Two fixing plates are spaced apart on the adjacent sides of the mounting plate and the base plate away from the support plates, facilitating assembly. The spaced arrangement of the support plates and fixing plates also facilitates avoidance of movement with the traveling truss, resulting in a more compact structure.
[0013] Furthermore, the rotatable mechanical hook also includes a rotating gear, a washer, and a fixing bolt. The end face area of the connector connected to one end of the rod body is larger than the end face area of the other end of the connector, and the other end of the connector is provided with a screw hole. The rotating gear is fitted onto the other end of the connector, and a rack is provided on the circumference of the rotating gear. The rotating gear is connected to an external drive device. The washer is in close contact with the rotating gear, and the fixing bolt is threaded into the screw hole to fix the washer, the rotating gear, and the connector. The gear structure provides more stable drive, facilitates precise control of the rotation angle, allows for immediate stopping and starting, and enhances safety performance.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] The connector of this utility model connects to an external drive device. A fixed sleeve and hook are fixed to a rotating rod. The periphery of the fixed sleeve abuts against the frame, limiting the frame's swaying during transport and improving placement accuracy. The hook protrudes from the fixed sleeve to hook the frame. During the process of lowering the hook to retrieve materials or removing the frame after stacking, the length direction of the hook is parallel to the length direction of the frame. When the hook is lowered to the set position, the external drive device drives the connector to rotate the fixed sleeve and hook together by a set angle via the rod body. The rotated hook is then positioned precisely at the hooking and fixing position on the frame. This design makes efficient use of space, reduces the required working space, allows for denser stacking in the stacking area, improves space utilization efficiency and the number of stacks, and saves costs.

[0024] The following is in conjunction with the appendix Figure 1-3 The embodiments of this utility model will be described in further detail below.
[0025] Rotatable mechanical hook 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a rotating rod 2, a fixed sleeve 3 sequentially disposed at one end of the rotating rod 2, and a hook 4. The rotating rod 2 includes a rod body 21 and a connector 22. The fixed sleeve 3 is fixedly connected to one end of the rod body 21, and the periphery of the fixed sleeve 3 abuts against the product being hooked. One end of the hook 4 is fixedly connected to one end of the rod body 21, and the other end of the hook 4 protrudes from the fixed sleeve 3. The central axis of the fixed sleeve 3 and the length direction of the hook 4 are arranged in an L-shape. The connector 22 is fixedly connected to the other end of the rod body 21. The connector 22 is used to connect to an external driving device to drive the rod body 21, the fixed sleeve 3, and the hook 4 to rotate at a set angle.
[0026] Specifically, connector 22 connects to an external drive device. The fixed sleeve 3 and hook 4 are fixed to the rotating rod 2. The periphery of the fixed sleeve 3 abuts against the frame, limiting the frame's sway during transport and improving placement accuracy. The hook 4 protrudes from the fixed sleeve 3 to hook the frame. During the process of lowering the hook 4 to retrieve materials or removing the frame after stacking, the length direction of the hook 4 is parallel to the length direction of the frame. When the hook 4 is lowered to the set position, the external drive device drives connector 22 to rotate the fixed sleeve 3 and hook 4 together by a set angle via the rod body 21. After rotation, the hook 4 is positioned precisely at the hooking and fixing position of the frame, making efficient use of space, reducing the required working space, allowing for denser stacking in the stacking area, improving space utilization efficiency and the number of stacks, and saving costs.
[0027] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, to ensure the stability of the frame during handling, the distances from the periphery of the fixing sleeve 3 to the center of the rod body 21 are set differently. When the hook 4 picks up the product, the distance between the periphery of the fixing sleeve 3 and the product is minimized, which can further reduce the movable space of the frame, thereby reducing the amplitude of frame swaying and the distance of misalignment during transportation, and improving the stacking accuracy and efficiency.
[0028] Preferably, the fixing sleeve 3 is a cylindrical structure, and the fixing sleeve 3 is eccentrically positioned with the rotating rod 2, resulting in a simple structure and low cost. Of course, the fixing sleeve 3 can also be an elliptical structure or other irregular shapes.
[0029] In some embodiments, please refer to Figure 2 The rotating rod 2 has a first groove 23 along its length at one end. The fixed sleeve 3 has a through first fixing groove, and a second groove 31 is formed on the wall of the first fixing groove corresponding to the position of the first groove 23. The end of the hook 4 has a through second fixing groove, and one end of the rotating rod 2 passes through the first fixing groove and the second fixing groove in sequence. A third groove 43 is formed on the wall of the second fixing groove corresponding to the position of the first groove 23. The first groove 23, the second groove 31, and the third groove 43 form a connected closed area. A flat key is provided within the closed area to enable the rotating rod 2, the fixed sleeve 3, and the hook 4 to rotate synchronously, improving the overall linkage stability. The structure is simple and easy to install and disassemble. The flat key structure is not shown in the figure.
[0030] In some embodiments, please refer to Figure 2 , Figure 3The hook 4 includes a square fixing part 41 and a conical supporting part 42. The fixing part 41 is connected to the rotating rod 2, and the supporting part 42 is fixedly connected to the side of the fixing part 41. The side of the supporting part 42 that contacts the product is set as a plane, and the other side of the supporting part 42 is provided with a weight-reducing groove 44. The thickness of the supporting part 42 decreases in the direction away from the rotating rod 2, which reduces cost, reduces the space occupied, and facilitates the alignment of the supporting part 42 to the corresponding hooking position.
[0031] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 The rotatable mechanical hook 1 also includes a mounting base 5. A bearing seat 6 is located in the middle of the mounting base 5, and the other end of the rod body 21 passes through the bearing seat 6 and connects to the connector 22, facilitating easy installation and disassembly and improving rotational stability. The hook 4 is located on the side of the mounting base 5 closest to the frame, allowing it to extend after rotation and providing sufficient hooking and bearing space for more stable gripping.
[0032] Specifically, the fixed base 5 includes a base plate 51, a mounting plate 52, two support plates 53, and two fixing plates 54. The base plate 51 and the mounting plate 52 are arranged parallel to each other at the top and bottom. A support plate 53 is connected to each side of the mounting plate 52 opposite to the base plate 51, and the support plate 53 is located on the side of the base plate 51 where the fixing sleeve 3 is provided. Two fixing plates 54 are spaced apart on the adjacent sides of the mounting plate 52 and the base plate 51 away from the support plates 53, which facilitates assembly. The spaced arrangement of the support plates 53 and fixing plates 54 facilitates avoidance of movement with the traveling truss, resulting in a more compact structure.
[0033] In some embodiments, please refer to Figure 1 , Figure 2 The rotatable mechanical hook 1 also includes a rotating gear 7, a washer 8, and a fixing bolt 9. The end face area of the connector 22 connected to one end of the rod body 21 is larger than the end face area of the other end of the connector 22, and a screw hole is provided at the other end of the connector 22. The rotating gear 7 is fitted onto the other end of the connector 22, and a rack is provided around its circumference. The rotating gear 7 is connected to an external drive device. The washer 8 is tightly fitted to the rotating gear 7, and the fixing bolt 9 is threaded into the screw hole to fix the washer 8, the rotating gear 7, and the connector 22. The gear structure provides more stable drive, facilitates precise control of the rotation angle, allows for easy stopping and starting, and offers higher safety performance. In this embodiment, a motor or other drive device can be used to drive the horizontal movement of the strip-shaped ruler, thereby rotating the rotating gear 7. The rotation angle of the hook 4 is controlled by the horizontal movement stroke of the rack teeth, resulting in higher control precision.
[0034] Multiple rotatable mechanical hooks 1 are spaced apart on both sides of the planar transfer equipment. When in a standby state or after stacking is completed, the length direction of the hooks 4 is perpendicular to the direction when hooking the frame, so that the hooks 4 occupy the least space and maximize space utilization. When the hooks 4 need to hook the frame, the external drive device can drive the rotating gear 7 to rotate. The rotating gear 7 drives the connector 22, the rod body 21, the fixed sleeve 3 and the hooks 4 to rotate 90°, so that the hooks 4 are in the hooking position of the frame.
[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
