Description
Technical Field
[0001] This utility model relates to the field of stacking and handling equipment technology, and in particular to a mechanical hook drive device. Background Technology
[0002] Products are stacked in a frame. The production line transports the frame to the transfer platform of a planar transfer device. The planar transfer device then transfers and stacks the frame and its contents to the unloading area. Existing planar transfer devices have multiple mechanical hooks mounted on their trusses. The up-and-down movement of the trusses transports the mechanical hooks to the frame location for hooking operations. Currently, each mechanical hook is driven by a single motor, resulting in poor overall coordination, high cost, and significant space consumption. 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 mechanical hook drive device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A mechanical hook drive device includes a rotary drive module, a transmission module, and multiple mechanical hooks. The rotary drive module includes a rotary motor and a lead screw. The output shaft of the rotary motor is connected to the lead screw to drive the lead screw to rotate. A set of transmission modules is provided at both ends of the lead screw, and the two sets of transmission modules are symmetrically arranged along the center of the lead screw. The transmission module includes a push-pull unit and multiple teeth. One end of the push-pull unit is threaded to one end of the lead screw, and multiple teeth are spaced apart on both sides of the other end of the push-pull unit along the length direction of the lead screw. The length direction of the multiple teeth is the same as the length direction of the lead screw. Each tooth meshes with one mechanical hook, and the multiple teeth are all located within the area enclosed by the multiple mechanical hooks.
[0006] By adopting the above technical solution, a rotary motor drives a lead screw to rotate. The forward and reverse rotation of the lead screw can cause the two sets of transmission modules to move closer or further apart. When the lead screw rotates forward, the two sets of transmission modules move closer together, and multiple teeth move towards the lead screw. During the movement of the teeth, the mechanical hooks can rotate. Since the multiple teeth are located within the area enclosed by multiple mechanical hooks, this facilitates the synchronous rotation of the mechanical hooks on both sides towards each other and positioning them at the hooking position on the frame, resulting in higher work efficiency. When the lead screw rotates in reverse, the two sets of transmission modules move further apart, and multiple teeth move away from the lead screw. During the movement of the teeth, the mechanical hooks can rotate in the opposite direction, causing the mechanical hooks to detach from the frame. The rotation angle of the mechanical hooks can be controlled according to the movement stroke of the teeth, resulting in high control precision. One rotary motor can control the rotation of multiple mechanical hooks simultaneously, offering high adjustment precision, stronger linkage, lower cost, and space saving.
[0007] Furthermore, the push-pull unit includes a push-pull plate, a first pull rod, a second pull rod, and multiple connecting seats. The push-pull plate, the first pull rod, and the second pull rod form a U-shaped structure. The push-pull plate is threadedly connected to the lead screw. The horizontal direction of the push-pull plate is perpendicular to the length direction of the lead screw. The push-pull fixing structure is simple, occupies less space, and can simultaneously control the synchronous reverse rotation of the mechanical hooks on both sides. One end of the push-pull plate is connected to the first pull rod, and the other end of the push-pull plate is connected to the second pull rod. At least one connecting seat is fixedly connected to each of the first and second pull rods, and each connecting seat is fixedly connected to one of the teeth, making assembly more convenient.
[0008] Furthermore, the connecting seat includes a T-shaped connecting plate and an L-shaped connecting block, which has a simple structure, reasonable spacing, and saves cost and space. One end of the connecting plate is fixedly connected to one end of the connecting block, and the toothed strip is fixedly connected to the side of the other end of the connecting plate. The other side of the connecting block is fixedly connected to the corresponding first pull rod or second pull rod.
[0009] Furthermore, the mechanical hook includes a fixed base, a rotating gear, and a hook body. One side of the fixed base is fixed to the truss, and the rotating gear is disposed above the fixed base. The rotating gear is fixedly connected to the upper part of the hook body, and the circumference of the rotating gear meshes with the corresponding rack teeth. The hook body is rotatably connected to the fixed base, resulting in a more stable meshing connection and better control.
[0010] Furthermore, a slide rail is provided above the fixed base on one side of the rotating gear, and the length direction of the slide rail is consistent with the length direction of the rack teeth. A slider is provided on the side of the connecting plate opposite to the rack teeth, and the slider is slidably mounted on the slide rail to improve the running accuracy and stability of the rack teeth, thereby ensuring that the rotation angle of the mechanical hook is controllable.
[0011] Furthermore, the length of the rack teeth is greater than or equal to half the circumference of the rotating gear, which ensures that the mechanical hook can be rotated and adjusted at an angle of at least 90°, enabling complete obstacle avoidance operations and saving costs.
[0012] Furthermore, the first pull rod and the second pull rod have the same structure. Both ends of the first pull rod and the second pull rod are provided with external threads. The first pull rod and the second pull rod are threadedly connected to the corresponding connecting seat, which makes installation and disassembly convenient. It also makes it easy to adjust the position of the rack teeth according to the actual installation situation, thereby improving the installation accuracy and efficiency.
[0013] Furthermore, the rotary drive module also includes a reducer, two bearing seats, and two adjusting screws. The output shaft of the rotary motor is fixedly connected to the reducer, and the lead screw passes through the reducer. Each end of the lead screw is connected to an adjusting screw, and one end of each adjusting screw passes through the corresponding bearing seat and is fixedly connected to the push-pull unit. The bearing seats are fixed to the truss, and the adjusting screws are connected to the bearing seats via bearings. This design is simple, facilitates installation and disassembly, and reduces costs.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] This invention utilizes a rotary motor to drive a lead screw. The forward and reverse rotation of the lead screw can cause two sets of transmission modules to move closer or further apart. When the lead screw rotates forward, the two sets of transmission modules move closer together, and multiple teeth move towards the lead screw. During this movement, the teeth drive the mechanical hooks to rotate. Since the multiple teeth are located within the area enclosed by multiple mechanical hooks, this facilitates the synchronous rotation of the mechanical hooks on both sides towards each other and positioning them at the hooking position on the frame, resulting in higher work efficiency. When the lead screw rotates in reverse, the two sets of transmission modules move further apart, and multiple teeth move away from the lead screw. During this movement, the teeth drive the mechanical hooks to rotate in the opposite direction, causing them to detach from the frame. The rotation angle of the mechanical hooks can be controlled according to the movement stroke of the teeth, resulting in high control precision. One rotary motor can simultaneously control the rotation of multiple mechanical hooks, offering high adjustment accuracy, stronger linkage, lower cost, and space saving. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The embodiments of this utility model will be described in further detail below.
[0026] Mechanical hook drive device 1, such as Figure 1 , Figure 2 , Figure 4 As shown, it includes a rotary drive module 2, a transmission module 3, and multiple mechanical hooks 4. The rotary drive module 2 includes a rotary motor 21 and a lead screw 22. The output shaft of the rotary motor 21 is connected to the lead screw 22 to drive the lead screw 22 to rotate. A set of transmission modules 3 is provided at both ends of the lead screw 22, and the two sets of transmission modules 3 are symmetrically arranged along the center of the lead screw 22. The transmission module 3 includes a push-pull unit and multiple racks 32. One end of the push-pull unit is threaded to one end of the lead screw 22, and multiple racks 32 are spaced apart on both sides of the other end of the push-pull unit along the length direction of the lead screw 22. The length direction of the multiple racks 32 is the same as the length direction of the lead screw 22. Each rack 32 is meshed with a mechanical hook 4, and the multiple racks 32 are all located within the area enclosed by the multiple mechanical hooks 4.
[0027] A rotary motor 21 drives a lead screw 22 to rotate. The forward and reverse rotation of the lead screw 22 can cause the two sets of transmission modules 3 to move closer or further apart. When the lead screw 22 rotates forward, the two sets of transmission modules 3 move closer together, and multiple teeth 32 move in the direction of the lead screw 22. During the movement of the teeth 32, they can drive the mechanical hook 4 to rotate. Since the multiple teeth 32 are all located within the area enclosed by the multiple mechanical hooks 4, it is easy to synchronously drive the mechanical hooks 4 on both sides to rotate towards each other and be positioned at the hooking position of the frame 6, resulting in higher work efficiency. When the lead screw 22 rotates in reverse, the two sets of transmission modules 3 move further apart, and multiple teeth 32 move away from the lead screw 22. During the movement of the teeth 32, they can drive the mechanical hook 4 to rotate in the opposite direction, causing the mechanical hook 4 to disengage from the frame 6. The rotation angle of the mechanical hook 4 can be controlled according to the movement stroke of the teeth 32, resulting in high control precision. One rotary motor 21 can control the rotation of multiple mechanical hooks 4 simultaneously, resulting in high adjustment precision, stronger linkage, lower cost, and space saving.
[0028] In some embodiments, please refer to Figure 2 , Figure 3The push-pull unit includes a push-pull plate 311, a first pull rod 312, a second pull rod 313, and multiple connecting seats 314. The push-pull plate 311, the first pull rod 312, and the second pull rod 313 form a U-shaped structure, allowing for reasonable alignment with the truss 5 structure and making it very convenient to use. The push-pull plate 311 is threadedly connected to the lead rod 22. The horizontal direction of the push-pull plate 311 is perpendicular to the length direction of the lead rod 22. The push-pull fixing structure is simple, occupies little space, and can simultaneously control the synchronous reverse rotation of the mechanical hooks 4 on both sides. One end of the push-pull plate 311 is connected to the first pull rod 312, and the other end is connected to the second pull rod 313. At least one connecting seat 314 is fixedly connected to each of the first pull rod 312 and the second pull rod 313, and each connecting seat 314 is fixedly connected to a toothed bar 32, making assembly easier.
[0029] Preferably, the connecting seat 314 includes a T-shaped connecting plate 3141 and an L-shaped connecting block 3142, which has a simple structure, reasonable positioning, and saves cost and space. One end of the connecting plate 3141 is fixedly connected to one end of the connecting block 3142, and a toothed shank 32 is fixedly connected to the side of the other end of the connecting plate 3141. Specifically, the connecting block 3142 is located at the end of the connecting plate 3141 with a shorter length, and the toothed shank 32 is located at the end of the connecting plate 3141 with a wider width. The other side of the connecting block 3142 is perpendicular to the connecting plate 3141 and is fixedly connected to the corresponding first pull rod 312 or second pull rod 313.
[0030] In some embodiments, please refer to Figure 1 , Figure 2 The mechanical hook 4 includes a fixed base 41, a rotating gear 42, and a hook body 43. One side of the fixed base 41 is fixed to the truss 5, and the rotating gear 42 is disposed above the fixed base 41. The rotating gear 42 is fixedly connected to the upper part of the hook body 43, and the circumference of the rotating gear 42 meshes with the corresponding rack teeth 32. The hook body 43 is rotatably connected to the fixed base 41, resulting in a more stable meshing connection and better control.
[0031] A slide rail 33 is provided above the fixed base 41 on one side of the rotating gear 42, and the length direction of the slide rail 33 is consistent with the length direction of the rack 32. A slider is provided on the side of the connecting plate 3141 opposite to the rack 32. The slider is slidably mounted on the slide rail 33 to improve the running accuracy and stability of the rack 32, thereby ensuring that the rotation angle of the mechanical hook 4 is controllable.
[0032] Preferably, the length of the rack tooth 32 is greater than or equal to half the circumference of the rotating gear 42, which can ensure that the mechanical hook 4 can be rotated and adjusted at an angle of at least 90°, enabling complete avoidance operation and saving costs.
[0033] Specifically, the first pull rod 312 and the second pull rod 313 have the same structure. Both ends of the first pull rod 312 and the second pull rod 313 are provided with external threads. The first pull rod 312 and the second pull rod 313 are threadedly connected to the corresponding connecting seat 314, which makes installation and disassembly convenient. It also makes it easy to adjust the position of the rack tooth 32 according to the actual installation situation, thereby improving the installation accuracy and efficiency.
[0034] In some embodiments, please refer to Figure 1 The rotary drive module 2 also includes a reducer 23, two bearing seats 24, and two adjusting screws 25. The output shaft of the rotary motor 21 is fixedly connected to the reducer 23, and a lead screw 22 passes through the reducer 23. An adjusting screw 25 is connected to both ends of the lead screw 22, and one end of the adjusting screw 25 passes through the corresponding bearing seat 24 and is fixedly connected to the push-pull unit. The bearing seat 24 is fixed to the truss 5, and the adjusting screw 25 is connected to the bearing seat 24 by bearings. The structure is simple, installation and disassembly are more convenient, and the cost is lower.
[0035] When the frame 6 is hooked, the truss 5 descends to the set position, the rotary motor 21 starts and drives the lead screw 22 to rotate. The lead screw 22 drives the adjusting screws 25 at both ends to rotate. Under the action of the adjusting screws 25, the corresponding push-pull units move closer to each other. The rack teeth 32 also move closer to the lead screw 22 under the action of the corresponding first pull rod 312 or second pull rod 313. The rack teeth 32 drive the rotating gear 42 to rotate, thereby causing the hook body 43 to rotate towards one side of the frame 6. At this time, the bearing part of the hook body 43 is located inside the frame 6, and the frame 6 can be lifted by raising the truss 5. Since the rotating gears 42 of the mechanical hooks 4 on both sides of the frame 6 are located on the opposite side of the corresponding rack teeth 32, when the rack teeth 32 on both sides move synchronously, they can drive the mechanical hooks 4 on both sides to rotate towards each other.
[0036] After frame 6 is placed in the stacking position, rotary motor 21 reverses, driving lead screw 22 to reverse, thereby causing the two sets of push-pull units to move away from each other under the action of adjusting screw 25. The rack tooth 32 also moves away from lead screw 22 under the action of the corresponding first pull rod 312 or second pull rod 313. The rack tooth 32 drives rotary gear 42 to rotate in the opposite direction, thereby causing hook body 43 to rotate in the opposite direction until mechanical hook 4 is located within the gap between two adjacent stacking areas, lifting truss 5 and moving it out of the stacking area.
[0037] 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.
