Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a vertical transport tool for an I-shaped wheel. Background Art

[0002] During the steel cord production process, spools are typically used to wind the steel cord to meet winding requirements. Within the steel cord production and processing workshop, spools are often transferred between different processing steps. Traditionally, operators transfer spools within the workshop using a combination of manual handling and cart transport. This method of transporting spools significantly increases the operator's workload. Whether the spool is fully wound with steel cord or empty, it is difficult for humans to repeatedly bear the weight for extended periods of time.

[0003] Currently, steel cord production workshops are equipped with cranes to reduce the workload of operators during material transfer. Operators use the crane to transfer spools, which raises the question of how to clamp the spools to the crane. Existing techniques for hoisting spools use wire rope lashing or U-shaped slings threaded through the spool's core shaft. However, in practice, these hoisting structures are complex to install and disassemble, and the spools lack stability during transfer, posing a potential safety hazard. Summary of the Invention

[0004] In view of the technical problems existing in the prior art in handling spools, the first aspect of the present invention provides a vertical handling tool for spools, comprising:

[0009] The upper end of each lifting claw is connected to the bottom of the pull rod. When the pull rod slides downward relative to the sleeve, the lower ends of multiple lifting claws move inward synchronously until they reach a clamping position. In the clamping position, the lifting claws can clamp the rim of the I-shaped wheel. When the pull rod slides upward relative to the sleeve, the lower ends of multiple lifting claws move outward synchronously until they reach a release position. In the release position, the lifting claws are separated from the rim of the I-shaped wheel.

[0010] Preferably, a cavity is provided inside the sleeve, and a connecting structure extending into the cavity is provided at the bottom of the pull rod. The connecting structure is connected to the lifting claw through a connecting rod extending out of the cavity.

The outer wall of the pull rod is provided with a limiting groove, and the positioning ring is provided with a positioning pin that can be inserted into the limiting groove. The positioning pin slides in the limiting groove to limit the extreme position of the pull rod relative to the sleeve, so that the lifting claw switches between the clamping position and the release position.

[0016] Preferably, the positioning ring can rotate relative to the sleeve, and the limiting groove includes a first strip groove, a second strip groove and a third strip groove. The second strip groove is arranged along the axial direction of the pull rod, the first strip groove is connected to the top end of the second strip groove, and the third strip groove is connected to the bottom end of the second strip groove. The first strip groove and the third strip groove are arranged along the circumferential direction of the pull rod. When the positioning pin slides in the second strip groove, the hanging claw moves between the clamping position and the release position. When the positioning pin slides in the first strip groove, the hanging claw remains in the release position.

[0030] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0031] In a first aspect, the present invention provides a vertical spool handling tool. This tool is designed to be used in conjunction with a crane system and is primarily used to carry spools in a vertical position. A vertical spool is one whose axis is aligned vertically. This type of spool features a rim of the wheel disc that serves as a gripping point. By gripping the rim of the wheel disc with the tool, the spool can be clamped and moved to a desired location using the crane system, such as from a full-line reel area to a cart.

[0032] Combine Figure 1 As shown, the handling tool mainly includes a lifting plate 10, a sleeve 20, a pull rod 30, a positioning ring 40, and multiple lifting claws 50. The lifting plate 10 is provided with at least three lifting claw grooves 11. The sleeve 20 is connected to the top of the lifting plate 10. The pull rod 30 is arranged on the inner side of the sleeve 20 and is slidably connected to the sleeve 20. A lifting ring 31 is provided on the top of the pull rod 30. The lifting ring 31 is connected to the overhead lifting system. The positioning ring 40 is connected to the top of the sleeve 20 and is sleeved on the outer wall of the pull rod 30. Each lifting claw 50 is connected to a lifting claw groove 11.

[0033] In this way, the lifting plate 10 constitutes the supporting structure of the lifting claw 50, and the cooperation of the sleeve 20 and the pull rod 30 can drive the lifting claw 50 to complete the switching of the grasping and releasing positions. Since the sleeve 20 and the lifting plate 10 are relatively fixed, during operation, it is only necessary to control the position of the lifting plate 10 through the overhead crane, and then control the position state of the pull rod 30 to realize the grasping and releasing of the I-shaped wheel by the lifting claw 50.

[0034] Further, combined Figure 2 As shown, the upper end of each lifting claw 50 is connected to the bottom of the pull rod 30. When the pull rod 30 slides upward relative to the sleeve 20, the lower ends of the multiple lifting claws 50 move inward synchronously until they reach the clamping position. In the clamping position, the lifting claws 50 can clamp the rim of the I-shaped wheel. When the pull rod 30 slides downward relative to the sleeve 20, the lower ends of the multiple lifting claws 50 move outward synchronously until they reach the release position. In the release position, the lifting claws 50 are separated from the rim of the I-shaped wheel.

[0035] It can be seen that when the pull rod 30 moves downward relative to the sleeve 20, the lifting claw 50 opens and is in the release position. When the pull rod 30 moves upward relative to the sleeve 20, the lifting claw 50 retracts and is in the clamping position. Since the pull rod 30 is always in a state of being pulled upward when the overhead crane system is lifting and transporting tools, it is beneficial to keep the lifting claw in a clamping state. Only when the user manually presses the pull rod 30 downward, the lifting claw 50 opens to clamp the edge of the I-shaped wheel 100.

[0036] Further, a limiting groove 33 is provided on the outer wall of the pull rod 30, and a positioning pin 42 that can be inserted into the limiting groove 33 is provided on the positioning ring 40. The positioning pin 42 slides in the limiting groove 33 to limit the extreme position of the pull rod 30 relative to the sleeve 20, enabling the lifting claw 50 to switch between the clamping position and the release position and to remain in the clamping position or the release position.

[0037] In this way, in order to keep the lifting claw 50 in a relatively stable position when clamping and releasing the spool 100, the provided limiting groove 33 can control the position state of the pull rod 30. That is, before clamping the spool, the user holds the pull rod 30 in the downward-pressed position, so that the pull rod 30 does not need to be continuously pressed. After the tool reaches above the spool 100, the holding state of the lifting claw 50 is released, enabling the lifting claw 50 to move from the release position to the clamping position, and then controlling the pull rod 30 to remain in the clamping position. In this way, the spool will not fall off during the hoisting process.

[0038] Combined with Figure 3 and <000009y>As shown, the positioning ring 40 can rotate relative to the sleeve 20. Among them, an annular groove 43 is provided on the part of the positioning ring 40 extending into the sleeve 20, and a positioning screw 22 is provided on the outer wall of the sleeve 20. The positioning screw 22 extends into the annular groove 43 to axially fix the positioning ring 40 and the sleeve 20 relative to each other along the axis of the sleeve 20.

[0039] When assembling the positioning ring 40, before installing the positioning screw 22, insert the positioning ring 40 into the upper end of the sleeve 20 so that the positions of the annular groove 43 and the hole of the positioning screw 22 correspond, and then insert the positioning screw 22 into the sleeve 20 so that the positioning screw extends into the annular groove 43. In this way, the positioning ring 40 can only rotate relative to the sleeve 20 and is fixed in the axial direction. <00,00095>Combined with Figure 4 As shown, the limiting groove 33 includes a first strip-shaped groove 331, a second strip-shaped groove 332, and a third strip-shaped groove 333. The second strip-shaped groove 332 is arranged along the axial direction of the pull rod 30. The first strip-shaped groove 331 is connected to the top end of the second strip-shaped groove 332, and the third strip-shaped groove 333 is connected to the bottom end of the second strip-shaped groove 332. The first strip-shaped groove 331 and the third strip-shaped groove 333 are arranged along the circumferential direction of the pull rod 30.

[0041] Among them, the first strip-shaped groove 331, the second strip-shaped groove 332, and the third strip-shaped groove 333 are in a "C" shape. The two horizontal grooves are the first strip-shaped groove 331 and the third strip-shaped groove 333, and the one vertical groove is the second strip-shaped groove 332.

[0042] In this way, when the positioning pin 42 slides in the second strip groove 332, the lifting claw 50 moves between the clamping position and the release position, especially when the positioning pin 42 is at the top of the second strip groove 332, the pull rod 30 is at the lower limit position relative to the sleeve 20, and the lifting claw 50 is in the release position at this time. When the positioning pin 42 slides in the first strip groove 331, the lifting claw 50 remains in the release position. When the positioning pin 42 is at the bottom of the second strip groove 332, the pull rod 30 is at the upper limit position relative to the sleeve 20, and the lifting claw 50 is in the clamping position. When the positioning pin 42 slides in the third strip groove 333, the lifting claw 50 remains in the clamping position.

[0043] Furthermore, the widths of the first strip groove 331 and the third strip groove 333 match the outer diameter of the positioning pin 42. In this way, when the pull rod 30 is at the upper limit position and the lower limit position, no shaking occurs.

[0044] Furthermore, the outer wall of the positioning ring 40 is also connected to a handle 41. In this way, the rotation angle of the positioning ring 40 can be controlled by the handle 41, and the relative positions of the sleeve 20 and the pull rod 30 in the axial direction can also be controlled by the handle 41.

[0045] Combine Figure 1 and Figure 2 As shown, a cavity is provided inside the sleeve 20, and a connecting structure 32 extending into the cavity is provided at the bottom of the pull rod 30. The connecting structure 32 is connected to the hanging claw 50 through a connecting rod 321 extending out of the cavity. When the pull rod 30 slides along its axial direction relative to the sleeve 20, the angle of the connecting rod 321 relative to the pull rod 30 changes.

[0046] In this way, the bottom of the pull rod 30 is connected to the hanging claw 50 through the connecting rod 321, and the displacement of the bottom of the pull rod 30 can be transmitted to the hanging claw 50 through the connecting rod 321, thereby controlling the hanging claw 50 to complete the position switching.

[0047] Furthermore, the outer wall of the sleeve 20 is provided with a slot 201 connected to the cavity, and the connecting rod 321 passes through the slot 201 . The first end of the connecting rod 321 is hinged to the connecting structure 32 , and the second end is hinged to the hanging claw 50 .

[0048] In this way, the displacement of the pull rod 30 inside the sleeve 20 can be transmitted to the outside of the sleeve 20 , and the pull rod 30 is arranged inside the sleeve 20 , which is conducive to controlling the position state of the pull rod 30 through the positioning ring 40 .

[0049] Combine Figure 3As shown, the lifting claw 50 is constructed as a Z-shaped structure, including a first connecting structure 51 in the middle area, a second connecting structure 52 in the upper area and a clamping portion 53 in the lower area. The first connecting structure 51 is hingedly connected to the connecting structure 32, the second connecting structure 52 is hingedly connected to the lifting claw groove 11, and the clamping portion 53 is configured to have a hook-shaped structure extending toward the inside of the hanging plate 10.

[0050] Specifically, the clamping portion 53 is closer to the first connecting structure 51 than the second connecting structure 52 is to the first connecting structure 51. Therefore, the lifting claw 50 acts as a lever structure. When a smaller force is applied to the second connecting structure 52, a larger force can be generated at the clamping portion 53. Moreover, when the pull rod 30 is in the upper limit position, the connecting rod 321 is perpendicular to the pull rod 30, and the second connecting structure 52 is perpendicular to the connecting rod 321. Therefore, if the clamping portion 53 moves outward, it can only compress the connecting rod 321, or the angle of the connecting rod 321 changes. It can be seen that the lifting claw 50 has a strong self-locking ability when it is in the clamping position, and can maintain a stable state of clamping the I-shaped wheel 100.

[0051] Furthermore, when the pull rod 30 moves downward, the clamping portion 53 rotates around the first connecting structure 51 toward the outside of the hanging plate 10 , and when the pull rod 30 moves upward, the clamping portion 53 rotates around the first connecting structure 51 toward the inside of the hanging plate 10 .

[0052] During the lifting process, the pull rod 30 always tends to move upward, so the clamping portion 53 will keep clamping the spool.

[0053] In an optional embodiment, a slot is provided in the center of the hanging plate 10, and the positioning plate 21 at the bottom of the sleeve 20 is inserted into the slot, and the positioning plate 21 is fixed to the hanging plate 10 by screws. In this way, the sleeve 20 and the hanging plate 10 are facilitated to be assembled.

[0054] Preferably, the positioning plate 21 at the bottom of the sleeve 20 can extend to the bottom of the hanging plate 10, and in particular can be inserted into the shaft hole of the I-shaped wheel, so as to facilitate positioning the hanging plate 10 at the center of the I-shaped wheel.

[0055] The method for transporting the spool using the vertical transport tool for the spool comprises the following steps:

[0056] Step 1: Use the overhead crane system to move the handling tool to the top of the spool to be transported;

[0057] Step 2: Rotate the positioning ring 40 and adjust the position of the positioning pin 42 so that the positioning pin 42 is in the first strip groove 331 . At this time, the lifting claw 50 remains in the release position.

[0058] Step 3: Place the lifting plate 10 close to the wheel surface of the spool and approximately in the center. At this time, the lifting claw 50 is located outside the wheel surface of the spool;

[0059] Step 4: Rotate the positioning ring 40 so that the positioning pin 42 enters the second strip groove 332, and at the same time pull the pull rod 30 upward to put the lifting claw 50 in the clamping position. At this time, the lifting claw 50 clamps the wheel surface of the I-shaped pulley;

[0060] Step 5: Rotate the positioning ring 40 so that the positioning pin 42 is in the third strip groove 333. At this time, the lifting claw 50 remains in the clamping position.

[0061] Step 6: Use the overhead crane system to move the clamped spool to the target location until the bottom of the spool is supported by the target area.

[0062] Step 7: Rotate the positioning ring 40 and adjust the position of the positioning pin 42 to disengage the positioning pin 42 from the third strip groove 333 , and press the pull rod 30 downward to move the lifting claw 50 from the clamping position to the release position, thereby releasing the I-shaped pulley;

[0063] Repeat steps 1 to 7 until the spool is moved.

[0064] Combine Figures 5 to 7 As shown, in a specific process of clamping the spool, the user holds the handle 41 with one hand, grabs the pull rod 30 with one hand, holds the handle 41 with one hand, and presses the pull rod 30 downward with the other hand to put the lifting claw 50 in the release position, as shown in FIG. Figure 5 As shown, control the position of the tool to make the upper end surface of the hanging plate 10 and the spool 100 fit together, then pull the rod 30 upwards to combine Figure 6 As shown, the claw 50 changes from the release position to the clamping position, and then the handle 41 is rotated to move the positioning pin 42 to the third strip groove 333, as shown in FIG. Figure 7 As shown, at this time, the lifting claw 50 remains in the clamping position, and the spool can be transferred to the target by using the overhead crane system.

[0065] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
