Description

Technical Field

[0001] This invention relates to a lifting device placement rack, and more specifically, to a crane hook placement rack and its method of use. Background Technology

[0002] In existing industrial production, the placement of lifting hooks is cumbersome, generally requiring manual loading and unloading of lifting equipment, especially heavy lifting equipment, which is inconvenient and time-consuming. When using lifting equipment, manual labor is needed in conjunction with overhead cranes for loading and unloading. Specifically, when the hook is lowered, manual labor is required to guide and pull the hook to place it on the placement frame. However, improper operation can easily lead to pinching injuries or falling and crushing injuries, causing production accidents. Therefore, it is necessary to propose a new placement device. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a crane hook placement rack and a method of use, which eliminates the need for manual operation to place hooks of various specifications, and allows for more orderly placement, thereby improving the efficiency of hook loading and unloading.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A crane hook placement frame includes a support frame and a placement base plate. The placement base plate is located above the support frame. The support frame includes a base and a support rod. The bottom end of the support rod is fixedly connected to the base, and the top end of the support rod is fixedly connected to the placement base plate.

[0006] Multiple placement components are provided on the placement base plate. Each placement component includes two inclined support plates. The inner side of each support plate is provided with a snap-fit ​​position. A space for accommodating a hook is formed between the two support plates. The hook enters the placement component from top to bottom, and the two sides of the hook are respectively engaged with the snap-fit ​​positions of the two support plates.

[0007] In one embodiment, the inner side of the support plate is provided with a plurality of parallel positioning protrusions, and a snap-fit ​​position is formed between every two adjacent positioning protrusions.

[0008] In one embodiment, the inner side of the support plate is provided with multiple docking slots, the number of which is the same as the number of snap-fit ​​positions in the same support plate, and the multiple docking slots are respectively located above the multiple snap-fit ​​positions. A locking mechanism is provided in the docking slot, the locking mechanism including a connecting plate and two positioning baffles. The two positioning baffles are respectively provided at the left and right ends of the connecting plate, forming a locking position between the two baffles that contacts the side of the hook. The connecting plate is fitted into the docking slot. The two corresponding locking mechanisms in the two support plates serve as a set of guide components for receiving a hook. The docking slot is provided with a through hole penetrating the support plate. A wire rope is provided on the side of the connecting plate facing the docking slot. The wire rope passes through the through hole, and the end of the wire rope hangs down towards the base. A connecting hook is provided at the end of the wire rope.

[0009] A locking belt is provided on the top surface of the two positioning protrusions. One end of the locking belt is fixedly connected to one of the positioning protrusions, and the other end of the locking belt is detachably connected to the other positioning protrusion.

[0010] A rotating mechanism is installed on the base. The rotating mechanism includes a drive motor and a rotating disk. The drive motor is horizontally installed on the base. The drive motor's transmission shaft is connected to the rotating disk, driving the rotating disk to rotate. Multiple hanging rings are installed on the circumferential side of the rotating disk to facilitate connection with the connecting hook at the end of the wire rope.

[0011] In one embodiment, the length of the wire rope is greater than the height between the through hole and the base.

[0012] In one embodiment, the drive motor is equipped with a torque sensor.

[0013] In one embodiment, a horizontal moving mechanism is also provided on the base. The horizontal moving mechanism includes a horizontal lead screw device and a connecting seat, and the connecting seat is connected to the moving part of the horizontal lead screw device.

[0014] The following are the steps for using a crane hook placement rack:

[0015] When the hook descends above the overhead crane hook placement frame, pull out a set of guide components inside the lower placement assembly, and lock the two locking mechanisms of the set to both sides of the hook using locking belts. Then, connect the ends of the wire ropes of the two locking mechanisms to the hanging rings on the circumferential side of the rotating disk.

[0016] As the hook continues to descend, the drive motor starts, causing the rotating disk to rotate. This causes the wire ropes of the two locking mechanisms to wind around the circumference of the rotating disk, thereby pulling the hook downward and guiding it to the corresponding snap-fit ​​position for the component below.

[0017] After the hook enters the placement component and stabilizes, the hook separates from the overhead crane, the locking belt is released, and the hook is then fixed by the snap-fit ​​station of the placement component.

[0018] In one embodiment, when the torque sensor detects that the torque is greater than a preset value, it indicates that the downward pull of the wire rope on the hook is too large. The drive motor stops until the torque drops to the preset value, at which point the drive motor restarts.

[0019] In one embodiment, before the hook is lowered, the horizontal moving mechanism drives the rotating mechanism to move below the placement assembly directly below the hook, while keeping the position of the rotating mechanism unchanged.

[0020] After the hook is stably placed inside the placement assembly, the wire rope separates from the rotating mechanism, and the horizontal moving mechanism drives the rotating mechanism to move and reset.

[0021] In summary, the present invention has the following beneficial effects:

[0022] This invention utilizes the hook placement frame of an overhead crane to guide the hook during its descent, enabling the hook to automatically and accurately enter the placement assembly. This eliminates the need for manual operation when placing hooks of various specifications, resulting in more orderly placement and improved hook loading and unloading efficiency.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0029] A crane hook placement frame includes a support frame and a placement base plate 3, such as Figure 1As shown, the placement base 3 is located above the support frame. The support frame includes a base 1 and a support rod 2. The bottom end of the support rod 2 is fixedly connected to the base 1, and the top end of the support rod 2 is fixedly connected to the placement base 3. Multiple placement components are provided on the placement base 3. Each placement component includes two inclined support plates 4. The inner side of the support plates 4 is provided with snap-fit ​​positions. A space for accommodating hooks 6 is formed between the two support plates 4. The hooks 6 enter the placement components from top to bottom. The two sides of the hooks 6 are respectively engaged with the snap-fit ​​positions of the two support plates 4. Therefore, the hooks 6 can be stably stored on the placement frame.

[0030] The crane hook placement rack of the present invention avoids direct manual operation for placing hooks 6 of various specifications. When placing hooks 6, the crane moves above the crane hook placement rack or moves the crane hook placement rack directly below the crane, and the crane gradually lowers the hooks 6 into the placement assembly. Conversely, when the crane lifts the hooks 6, it can be lifted directly from the placement assembly.

[0031] like Figure 1 and 2 As shown, within a placement assembly, two support plates 4 are arranged in a trumpet shape, wider at the top and narrower at the bottom, facilitating the entry and exit of the hook 6 from the placement assembly. Furthermore, the placement assembly is suitable for hooks 6 of different specifications. Multiple snap-fit ​​positions are provided on one side of the support plate 4, and the other side's support plate 4 also has the same number of corresponding snap-fit ​​positions. The snap-fit ​​positions on both sides of the support plate 4 correspond one-to-one, forming multiple sets of snap-fit ​​stations. Each set of snap-fit ​​stations can accommodate one hook 6, such as... Figure 1 As shown, one placement assembly can accommodate two hooks 6.

[0032] More specifically, the inner side of the support plate 4 is provided with multiple parallel positioning protrusions 5, and a locking position is formed between every two adjacent positioning protrusions 5. It should be noted that the gap between adjacent locking positions is not large enough to accommodate the hook 6; that is, every two positioning protrusions 5 form a group, and a locking position is formed between groups of positioning protrusions 5.

[0033] Furthermore, taking the placement of hook 6 as an example, hook 6 still experiences a slight swaying during descent. To facilitate alignment of hook 6 with the locking position within the placement assembly, such as... Figure 3As shown, the present invention improves the placement component. Multiple docking slots are provided on the inner side of the support plate 4. The number of docking slots is the same as the number of snap-fit ​​positions in the same support plate 4. The multiple docking slots are located above the multiple snap-fit ​​positions. A locking mechanism 7 is provided in the docking slot. The locking mechanism 7 includes a connecting plate and two positioning baffles. The two positioning baffles are respectively provided at the left and right ends of the connecting plate. A locking position is formed between the two baffles to contact the side of the hook 6. The connecting plate is fitted and connected to the docking slot. The two corresponding locking mechanisms 7 in the two support plates 4 serve as a set of guide components to support a hook 6. The docking slot is provided with a through hole that penetrates the support plate 4. A wire rope 8 is provided on the side of the connecting plate facing the docking slot. The wire rope 8 passes through the through hole, and the end of the wire rope 8 hangs down towards the base 1. A connecting hook is provided at the end of the wire rope 8. The length of the wire rope 8 is greater than the height between the through hole and the base 1.

[0034] A locking belt is provided on the top surface of the two positioning protrusions 5. One end of the locking belt is fixedly connected to one of the positioning protrusions 5, and the other end of the locking belt is detachably connected to the other positioning protrusion 5, for example, by means of a belt buckle structure or a Velcro structure.

[0035] A rotating mechanism is provided on the base 1. The rotating mechanism includes a drive motor 10 and a rotating disk 9. The drive motor 10 is horizontally mounted on the base 1. The drive shaft of the drive motor 10 is connected to the rotating disk 9 to drive the rotating disk 9 to rotate. Multiple hanging rings are provided on the circumferential side of the rotating disk 9 to facilitate connection with the connecting hook at the end of the wire rope 8.

[0036] The guide assembly, in conjunction with the rotating mechanism, can guide the hook 6. The specific usage method is as follows:

[0037] When the hook 6 descends above the overhead crane hook placement frame, pull out a set of guide components inside the lower placement assembly upwards, and lock the two locking mechanisms 7 of the set to both sides of the hook 6 respectively through the locking belt. Then, connect the ends of the wire ropes 8 of the two locking mechanisms 7 to the hanging rings on the circumferential side of the rotating disk 9.

[0038] As the hook 6 continues to descend, the drive motor 10 starts, causing the rotating disk 9 to rotate. This causes the wire ropes 8 of the two locking mechanisms 7 to wind around the rotating disk 9 to the side, thereby pulling the hook 6 downward and guiding it to the corresponding snap-fit ​​position for placing the component below.

[0039] After the hook 6 enters the placement component and stabilizes, the hook 6 separates from the overhead crane, the locking belt is released, and the hook 6 is then fixed by the snap-fit ​​station of the placement component.

[0040] Conversely, when the hook 6 leaves the placement assembly, the locking belt is loosened, and the hook 6 is lifted upwards and removed.

[0041] The tension generated by the rotation of the rotating disk 9 is small and will not affect the connection between the overhead crane and the hook 6; it only serves a guiding function. In addition, the length of the wire rope 8 will not be too long. During the process of guiding the hook 6 to descend, the wire rope 8 will not wrap around the rotating disk 9 more than once. After the hook 6 enters the placement assembly and stabilizes, the wire rope 8 will separate from the rotating disk 9.

[0042] Furthermore, in order to reduce the adverse effects on the hook 6 and the overhead crane during the descent of the guide hook 6, a torque sensor is installed in the drive motor 10. When the torque sensor detects that the torque is greater than the preset value, it indicates that the downward pulling force of the wire rope 8 on the hook 6 is too large. The drive motor 10 will then pause until the torque drops to the preset value, at which point the drive motor 10 will restart.

[0043] Furthermore, a horizontal moving mechanism 12 is also provided on the base 1. The horizontal moving mechanism 12 includes a horizontal lead screw device and a connecting seat. The connecting seat is connected to the moving part 11 of the horizontal lead screw device. That is, the horizontal lead screw device drives the connecting seat to move horizontally, and the rotating mechanism is provided on the connecting seat.

[0044] The horizontal lead screw device is a conventional lead screw guiding and moving device, which includes at least a lead screw motor, a lead screw threaded component, a guide rod, a lead screw nut, and a moving component 11. The drive shaft of the lead screw motor is connected to one end of the lead screw threaded component, the lead screw nut is threaded to the lead screw threaded component, and the lead screw nut is slidably connected to the guide rod. The moving component 11 is connected to the lead screw nut. The lead screw motor drives the lead screw threaded component to rotate, causing the lead screw nut to move linearly, thereby realizing the linear movement of the moving component 11.

[0045] The function of the horizontal moving mechanism 12 is to drive the rotating mechanism to move on the base 1. The specific usage method is as follows:

[0046] Before the hook 6 descends, the horizontal moving mechanism 12 drives the rotating mechanism to move to below the placement assembly directly below the hook 6, and keeps the position of the rotating mechanism unchanged.

[0047] After the hook 6 is stably stored inside the placement assembly, the wire rope 8 separates from the rotating mechanism, and the horizontal moving mechanism 12 drives the rotating mechanism to move and reset.

[0048] During the descent of the hook 6, the present invention guides the hook 6 through the hook placement frame of the overhead crane, so that the hook 6 automatically and accurately enters the placement component. This eliminates the need for direct manual operation to place hooks 6 of various specifications, and results in a more orderly arrangement, thereby improving the loading and unloading efficiency of the hook 6.

[0049] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
