Description

Technical Field

[0001] The present invention relates to the field of slings, and in particular to a wire drum sling and a use method thereof. Background Art

[0002] A wire barrel is a device used to guide, protect, or support wires or cables. Wires can be neatly arranged on the surface of the barrel for easy management and maintenance.

[0003] Wire reels with wire wrapped around their surfaces are typically heavy. During production, they are typically handled using a hoist, which holds the reel circumferentially and carries it along its circumference. To prevent damage to the wire insulation when the hoist grips the reel, the reel is typically rotated around its center hole. The outward pressure of the clamping block creates sufficient friction between the clamping block and the reel, ensuring a secure grip.

[0004] However, during the transfer process, due to the heavy weight of the wire barrel, deceleration or sudden stop during movement will cause the wire barrel to shake. Sometimes the shaking amplitude is too large and even causes the wire barrel to fall, affecting the life safety of surrounding workers. Summary of the Invention

[0005] The purpose of the present invention is to provide a wire barrel hanger and a method of using the same, which can ensure the reliability of the wire barrel clamping.

[0006] To achieve the above-mentioned object, the present invention provides a wire drum hanger, comprising a hanger body, a positioning member, a locking pin, and a locking drive drivingly connected to the locking pin, wherein the locking pin is slidably connected to the hanger body, a through hole is provided on the hanger body, and the locking drive drives the locking pin to extend or retract through the through hole;

[0007] The positioning piece is fixedly connected to the upper end of the wire barrel, and the positioning piece is provided with a locking hole matched with the locking pin.

[0008] Preferably, at least two locking pins are provided, and the plurality of locking pins are rotationally symmetrically arranged along the circumference of the sling body.

[0009] Preferably, the locking drive includes a driver, a driving mechanism connected to the driver, and a slider, the driver is connected to the spreader body, the spreader body is provided with a slide groove, the slider slides in cooperation with the slide groove, one end of the slider is connected to the driving mechanism, and the other end is connected to the locking pin, and the driver drives the slider to slide in the slide groove through the driving mechanism;

[0010] A plurality of slide blocks are provided, and the plurality of slide blocks are provided in one-to-one correspondence with the locking pins.

[0011] Preferably, the driving mechanism includes a rotating member and a connecting rod, one end of the connecting rod is connected to the outer edge of the rotating member, and the other end is connected to the slider, and the driver drives the rotating member to rotate;

[0012] There are multiple connecting rods, and the multiple connecting rods are arranged in a one-to-one correspondence with the sliding blocks.

[0013] Preferably, the driver is arranged for horizontal movement, the driver pushing the outer edge of the rotating member.

[0014] The present invention also provides a method for using the wire drum hanger, the method comprising:

[0015] Step 1: Control the spreader body so that the locking pin is aligned with the locking hole;

[0016] Step 2: Control the locking pin to extend from the through hole to the locking hole;

[0017] Step 3: After the wire barrel reaches the target position, control the locking pin to retract into the through hole.

[0018] Preferably, in step 2 and step 3, the driver is configured as a cylinder, and the wire spool hanger further comprises a control handle, on which a first control valve and a second control valve are provided, and the first control valve and the second control valve respectively control the extension and retraction of the locking pin.

[0019] Preferably, the wire drum hanger further comprises a pressure switch for controlling the extension of the cylinder, and the pressure switch is connected to the second control valve.

[0020] Preferably, the lower end of the sling body includes a limiting boss that cooperates with the inner hole of the positioning member, and the locking pin is slidably connected to the limiting boss;

[0021] A positioning rod is provided on the limiting boss, and a positioning groove matched with the positioning rod is provided on the positioning piece.

[0022] According to the above technical solution, the present invention can achieve reliable clamping of the wire barrel by the wire barrel hanger by fixing the positioning member on the wire barrel and cooperating the locking pin with the locking hole.

[0023] The locking drive extends the locking pin, which then pushes it into the locking hole on the positioning member. The locking pin and the locking hole cooperate to securely hold the wire bobbin in place. Retracting the locking pin releases the wire bobbin, separating the wire bobbin from the hoist.

[0024] Preferably, the radius of the lower end of the sling body is slightly smaller than the inner diameter of the wire barrel, so that after the lower end of the sling body enters the inner barrel of the wire barrel, the fitting clearance between the two is small. Then, when the wire barrel sling hoist lifts the wire barrel, the lower end of the sling body can exert a certain limiting effect on the wire barrel, so that there is no room for shaking between the wire barrel and the wire barrel sling during movement. In addition, the locking pin and the locking hole cooperate to prevent the wire barrel and the wire barrel sling from rotating relative to each other. When the wire barrel sling moves with the wire barrel, regardless of whether the wire barrel sling slows down or stops suddenly, the wire barrel will maintain a relatively stable positional relationship with the wire barrel sling and will not fall off the wire barrel sling, thereby ensuring the reliability of the wire barrel sling clamping the wire barrel.

[0025] Preferably, in order to facilitate the alignment of the locking pin and the locking hole, a positioning rod is also provided on the sling body, and a positioning groove that cooperates with the positioning rod is provided on the positioning piece. When moving the wire tube sling, the relative position of the wire tube sling and the wire tube can be determined by visually matching the positioning rod with the positioning groove. After the positioning rod is matched with the positioning groove, the locking pin can be extended, and at this time the locking pin can be aligned through the hole.

[0026] Preferably, the positioning groove is set to be V-shaped and has a certain depth. During the process of the positioning rod cooperating with the positioning groove, the positioning rod can slide downward along the side of the V-shaped positioning groove, and at the same time, the positioning rod will also slide toward the middle position of the V-shaped positioning groove. In this process, the sling body will rotate relative to the wire tube, and at the same time, the sling body will gradually approach the wire tube. In the process of the sling body gradually approaching the wire tube, the lower end of the sling body will eventually enter the inner tube of the positioning piece.

[0027] Therefore, by using the wire bobbin hanger, the locking pin and the locking hole cooperate to realize the reliable clamping of the wire bobbin hanger and the wire bobbin. When the wire bobbin hanger moves with the wire bobbin, no matter whether the wire bobbin hanger slows down or stops suddenly, the wire bobbin will maintain a relatively stable position relationship with the wire bobbin hanger and will not fall off the wire bobbin hanger, thereby ensuring the reliability of the wire bobbin hanger clamping the wire bobbin.

[0046] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0047] In the present invention, unless otherwise stated, directional words contained in terms such as "one end, the other end, outer surface, axis, cone, close to" merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0048] A wire drum hanger includes a hanger body 1, a positioning member 63, a locking pin 3, and a locking drive connected to the locking pin 3. The locking pin 3 is slidably connected to the hanger body 1. The hanger body 1 is provided with a through hole 11. The locking drive drives the locking pin 3 to extend or retract through the through hole 11.

[0049] The positioning member 63 is fixedly connected to the upper end of the wire barrel 6 , and the positioning member 63 is provided with a locking hole 62 that cooperates with the locking pin 3 .

[0050] By implementing the above technical solution, by fixing the positioning member 63 on the wire barrel 6 and by the cooperation between the locking pin 3 and the locking hole 62 , the wire barrel hanger can reliably clamp the wire barrel 6 .

[0051] The locking drive action extends the locking pin 3 outward, pushing it into the locking hole 62 on the positioning member 63. The locking pin 3 cooperates with the locking hole 62 to ensure that the wire bobbin hanger securely holds the wire bobbin 6. If the locking pin 3 is retracted, the wire bobbin hanger releases the wire bobbin 6, thereby separating the wire bobbin hanger from the wire bobbin 6.

[0052] Preferably, the radius of the lower end of the sling body 1 is slightly smaller than the inner diameter of the wire barrel 6, so that after the lower end of the sling body 1 enters the inner barrel of the wire barrel 6, the fitting clearance between the two is small. Then, when the wire barrel sling lifts the wire barrel 6, the lower end of the sling body 1 can exert a certain limiting effect on the wire barrel 6, so that during the movement, there is no room for shaking between the wire barrel 6 and the wire barrel sling. In addition, due to the cooperation between the locking pin 3 and the locking hole 62, the wire barrel 6 and the wire barrel sling will not produce relative rotation. When the wire barrel sling moves with the wire barrel 6, no matter whether the wire barrel sling slows down or stops suddenly, the wire barrel 6 will maintain a relatively stable positional relationship with the wire barrel sling and will not fall off the wire barrel sling, thereby ensuring the reliability of the wire barrel sling clamping the wire barrel 6.

[0053] Preferably, in order to facilitate the alignment of the locking pin 3 with the locking hole 62, a positioning rod 2 is also provided on the sling body 1, and a positioning groove 61 cooperating with the positioning rod 2 is provided on the positioning member 63. When the wire tube sling is moved, the relative position of the wire tube sling and the wire tube 6 can be determined by visually cooperating the positioning rod 2 with the positioning groove 61. After the positioning rod 2 cooperates with the positioning groove 61, the locking pin 3 can be extended, and at this time the locking pin 3 can be aligned with the through hole 11.

[0054] Preferably, the positioning groove 61 is set to be V-shaped and has a certain depth. During the cooperation between the positioning rod 2 and the positioning groove 61, the positioning rod 2 can slide downward along the side of the V-shaped positioning groove 61, and at the same time, the positioning rod 2 will also slide toward the middle position of the V-shaped positioning groove 61. During this process, the sling body 1 will rotate relative to the wire tube 6, and at the same time, the sling body 1 gradually approaches the wire tube 6. In the process of the sling body 1 gradually approaching the wire tube 6, the lower end of the sling body 1 will eventually enter the inner tube of the positioning member 63.

[0055] Therefore, by using the wire bobbin hanger, the locking pin 3 and the locking hole 62 can be used to cooperate to achieve reliable clamping of the wire bobbin hanger and the wire bobbin 6. When the wire bobbin hanger moves with the wire bobbin 6, no matter whether the wire bobbin hanger slows down or stops suddenly, the wire bobbin 6 will maintain a relatively stable position relationship with the wire bobbin hanger and will not fall off the wire bobbin hanger, thereby ensuring the reliability of the wire bobbin hanger clamping the wire bobbin 6.

[0056] In this embodiment, preferably, at least two locking pins 3 are provided, and the plurality of locking pins 3 are rotationally symmetrically arranged along the circumference of the spreader body 1 .

[0057] Multiple locking pins 3 are arranged symmetrically along the circumference of the hanger body 1. When the wire tube hanger clamps the wire tube 6 and completes the lifting of the wire tube 6, multiple evenly arranged locking pins 3 can provide uniform and reliable support for the wire tube 6, ensuring a relatively stable state between the wire tube 6 and the wire tube hanger, and avoiding frequent shaking or tilting of the wire tube 6 during the movement of the wire tube 6.

[0058] Preferably, the plurality of locking pins 3 are actuated simultaneously, so that the plurality of locking pins 3 can be extended or retracted simultaneously, thereby achieving reliable locking and unlocking of the wire barrel 6 .

[0059] Preferably, the locking pin 3 is provided in a one-to-one correspondence with the positioning rod 2, and a corresponding positioning rod 2 and a locking pin 3 are located on the same vertical line. During the process of the positioning rod 2 engaging with the positioning groove 61, the locking pin 3 will also rotate with the positioning rod 2 to a position corresponding to the locking hole 62. It is only necessary to set the front end of the locking hole 62 to have a larger diameter. The larger diameter can play a guiding role for the locking pin 3 when it cooperates with the locking pin 3. Under the joint guidance of the locking hole 62 and the V-shaped positioning groove 61, the locking pin 3 is more likely to enter the locking hole 62, which can significantly improve the success rate of the locking pin 3 engaging with the locking hole 62.

[0060] Moreover, after improving the matching success rate of the locking pin 3 and the locking hole 62 in this way, the matching clearance between the locking pin 3 and the locking hole 62 can also be set to be smaller, thereby avoiding the large shaking between the wire tube hanger and the wire tube 6 during the movement after the wire tube hanger is matched with the wire tube 6, thereby reliably reducing the dynamic load of the wire tube hanger during operation.

[0061] In this embodiment, preferably, the locking drive includes a driver, a driving mechanism connected to the driver, and a slider. The driver is connected to the sling body 1, the sling body 1 is provided with a slide groove 12, the slider slides in cooperation with the slide groove 12, one end of the slider is connected to the driving mechanism, and the other end is connected to the locking pin 3, and the driver drives the slider to slide in the slide groove 12 through the driving mechanism.

[0062] One end of the slider is in sliding engagement with the slide groove 12 . Under the action of the driver, the slider can reciprocate along the length direction of the slide groove 12 , thereby realizing the extension and retraction of the locking pin 3 at the other end of the slider.

[0063] Preferably, the chute 12 is arranged along the diameter of the spreader body 1. Then, when the slider moves, it moves along the diameter of the spreader body 1, and the locking pin 3 also extends or retracts along the diameter of the spreader body 1. At the same time, the locking hole 62 is arranged along the diameter of the positioning member 13, so that the locking hole 62 can easily cooperate with the locking pin 3.

[0064] A plurality of sliders are provided, and the plurality of sliders are provided in one-to-one correspondence with the locking pins 3. Preferably, the driving mechanism acts on the plurality of sliders at the same time, so that the plurality of sliders can act synchronously, thereby achieving the purpose of extending or retracting the plurality of locking pins 3 at the same time.

[0065] In one embodiment, two sliders are provided, and the corresponding chutes 12 of the two sliders are located on the same diameter of the sling body 1. The driver is provided as a rotatable structure such as a motor, and the driver is connected to the screw through a transmission structure, and the driver can drive the screw to rotate. Two nuts are respectively fitted at both ends of the screw, and the slider is sleeved outside the nut and fixedly connected to the nut. The nut cannot rotate due to the cooperation between the slider and the chute 12. Therefore, when the screw rotates, the nut will drive the slider to move linearly along the screw. When the driver drives the screw to rotate, the nuts at both ends of the screw will approach or move away from each other, thereby driving the locking pin 3 to synchronously extend or retract.

[0066] Preferably, the slider and the locking pin 3 are configured as an integral structure. When the screw rotates, the two nuts at both ends of the screw can simultaneously approach or move away from each other, so that the two locking pins 3 fixedly connected to the nuts can be synchronously extended or retracted.

[0067] In this embodiment, preferably, the driving mechanism includes a rotating member 42 and a connecting rod 43, one end of the connecting rod 43 is connected to the outer edge of the rotating member 42, and the other end is connected to the slider, and the driver drives the rotating member 42 to rotate;

[0068] A plurality of connecting rods 43 are provided, and the plurality of connecting rods 43 are provided in a one-to-one correspondence with the sliders.

[0069] When the number of locking pins 3 is greater than two, a driving mechanism using a rotating member 42 and a connecting rod 43 in cooperation with each other can achieve the effect of driving multiple sliders simultaneously.

[0070] The rotation center of the rotating member 42 coincides with the axis of the sling body 1, allowing the rotating member 42 to rotate about the axis of the sling body 1. The connecting rod 43 is connected to the outer edge of the rotating member 42. When the locking pin 3 is in the locked state, the connecting rod 43 and the slider are aligned, with an angle of 180° between them. This positions the locking pin 3 at the other end of the slider at its farthest distance from the rotating member 42. Subsequently, as the rotating member 42 rotates, the angle between the connecting rod 43 and the slider gradually decreases, causing the connecting rod 43 to pull the slider toward the rotating member 42. The distance between the slider and the outer edge of the rotating member 42 gradually decreases, causing the locking pin 3 to gradually retract. Therefore, during the rotation of the rotating member 42, the locking pin 3 switches from the locked state to the unlocked state.

[0071] Multiple connecting rods 43 are provided, each corresponding to a slider. The connecting rods 43 are arranged rotationally symmetrically along the circumference of the rotating member 42. When the locking pin 3 is locked, the connecting rods 43 and the slider are aligned. When the locking pin 3 is unlocked, the angle between the connecting rods 43 and the slider is minimized.

[0072] Preferably, the slider and the locking pin 3 are configured as an integral structure, and the connecting rod 43 is connected to the integral structure via a rotating shaft. During the rotation of the rotating member 42, the connecting rod 43 pushes or pulls the integral structure to extend or retract through the rotating pin.

[0073] In this embodiment, preferably, the driver is configured to move horizontally, and the driver pushes the outer edge of the rotating member 42 .

[0074] The driver is set to move horizontally, which can reduce the height of the wire drum hanger and prevent the wire drum 6 from occupying more height space.

[0075] The driver is set as a linear motion mechanism such as a cylinder 44, and the driver can drive the rotating member 42 to rotate through the driving rod 45. When the driver drives the rotating member 42, in order to ensure a reliable connection between the driving rod 45 and the driver, the driver is rotationally connected to the spreader body 1.

[0076] The driver pushes the edge of the rotating member 42 so that the driver only needs a relatively short telescopic stroke to obtain a sufficiently large rotation angle of the rotating member 42 .

[0077] The present invention also provides a method for using the wire drum hanger, the method comprising:

[0078] Step 1: Control the sling body 1 so that the locking pin 3 is aligned with the locking hole 62;

[0079] Step 2: Control the locking pin 3 to extend from the through hole 11 to the locking hole 62;

[0080] Step 3: After the wire barrel reaches the target position, the locking pin 3 is controlled to retract through the through hole 11.

[0081] Through the implementation of the above technical solution, the position of the hanger body 1 is first controlled so that the locking pin 3 is aligned with the locking hole 62, and then the locking drive action is controlled to extend the locking pin 3 from the through hole 11. The extended locking pin 3 will enter the locking hole 62, thereby achieving the purpose of locking the relative position of the wire tube hanger and the wire tube 6.

[0082] After the position of the wire tube hanger and the wire tube 6 is locked, the wire tube hanger can be rotated together with the wire tube 6 through the transfer structure. During the transfer process, the wire tube 6 can be kept in a relatively fixed position with the wire tube hanger, making the rotation process safer and there is no need to worry about the wire tube 6 falling off.

[0083] When the wire bobbin 6 reaches the target position, the locking pin 3 is controlled to retract into the through hole 11, thereby unlocking the wire bobbin 6 and separating the wire bobbin 6 from the wire bobbin hanger. Thereafter, when the rotating structure is controlled to transport the wire bobbin hanger, the wire bobbin 6 will be left in the target position, and the wire bobbin hanger will be transported so that the next wire bobbin 6 can be operated.

[0084] In this embodiment, preferably, the driver is configured as a cylinder 44, and the wire spool hanger further includes a control handle, on which a first control valve 51 and a second control valve 52 are provided, and the first control valve 51 and the second control valve 52 respectively control the extension and retraction of the locking pin 3.

[0085] By controlling the gas to enter the cylinder 44 from different ends, the extension and retraction of the telescopic rod of the cylinder 44 can be controlled.

[0086] The first control valve 51 and the second control valve 52 respectively control two air intake pipes, which are connected to both ends of the cylinder 44. By controlling the air intake of different air intake pipes, the telescopic rod of the cylinder 44 can be controlled to extend or retract.

[0087] Preferably, when the telescopic rod of the cylinder 44 is retracted to its maximum position, the locking pin 3 is locked. Since the piston is already at the bottom of the cylinder 44 at this time, the external force applied to the locking pin 3 is unlikely to pull out the piston of the cylinder 44, thus avoiding the problem of locking failure caused by external force driving the piston movement.

[0088] In this embodiment, preferably, the wire bobbin hanger further includes a pressure switch for controlling the extension of the air cylinder 44 .

[0089] The pressure switch is provided in the air intake pipe that supplies air to the rear end of the air cylinder 44 and is located in front of the second control valve 52 .

[0090] The pressure switch is equipped with a release button 54 and a preset pressure value. A pressure sensor is installed on the wire bobbin hoist to detect the actual load on the wire bobbin hoist. When the actual load falls below the preset pressure value of the pressure switch and the release button 54 is pressed, the air path on the pressure switch is connected, and the air intake pipe where the second control valve 52 is located is connected to the compressed air source. At this point, pressing the second control valve 52 allows air to enter the rear end of the cylinder 44, pushing the piston forward and extending the telescopic rod. The extension of the telescopic rod in the cylinder 44 activates the drive mechanism, retracting the locking pin 3 and switching it from a locked state to an unlocked state.

[0091] Therefore, in the actual production process, when the operator puts down the wire bobbin 6, the pressure sensor on the wire bobbin hanger will detect that the load on the wire bobbin hanger is less than the set value. At this time, the operator presses the release button 54 again, and the air circuit of the pressure switch will be connected. After that, the operator presses the second control valve 52 on the control handle to retract the locking pin 3, so that the wire bobbin hanger and the wire bobbin 6 are separated.

[0092] If the operator mistakenly operates and presses the release button 54 when the wire bobbin 6 is still hanging under the wire bobbin hanger, the pressure sensor detects that the load of the wire bobbin hanger is still greater than the set value, so the air circuit of the pressure switch will not be connected. Therefore, no compressed air will enter the rear end of the cylinder 44. At this time, even if the operator presses the first control valve 51, the wire bobbin 6 will not be released.

[0093] By providing a pressure switch, the release of the wire barrel 6 by the wire barrel hanger is made more reliable, which can effectively prevent the wire barrel 6 from being released at an inappropriate time due to misoperation of the wire barrel hanger.

[0094] In this embodiment, preferably, the lower end of the sling body 1 includes a limiting boss 13 that cooperates with the inner hole of the positioning member, and the locking pin 3 is slidably connected to the limiting boss 13;

[0095] A positioning rod 2 is provided on the limiting boss 13 , and a positioning groove 61 that cooperates with the positioning rod 2 is provided on the positioning member 63 .

[0096] The positioning rod 2 and the positioning groove 61 can conveniently fix the relative positions of the wire tube hanger and the wire tube 6, thereby allowing the locking pin 3 to enter the locking hole 62 conveniently and reliably.

[0097] Preferably, the positioning groove 61 is set to be V-shaped and has a certain depth. During the cooperation between the positioning rod 2 and the positioning groove 61, the positioning rod 2 can slide downward along the side of the V-shaped positioning groove 61, and at the same time, the positioning rod 2 will also slide toward the middle position of the V-shaped positioning groove 61. During this process, the limiting boss 13 will rotate relative to the wire tube 6. While rotating relative to each other, the limiting boss 13 will gradually approach the wire tube 6 and eventually enter the inner tube of the positioning member 63.

[0098] Therefore, after the wire tube hanger completes locking of the wire tube 6, the cooperation between the locking pin 3 and the locking hole 62 can limit the freedom of relative rotation between the wire tube and the wire tube hanger in the circumferential direction, and the cooperation between the limiting boss 13 and the inner hole of the positioning member 63 can limit the movement of the wire tube and the wire tube hanger. Therefore, by setting the limiting boss 13, a more reliable cooperation between the wire tube and the wire tube hanger can be achieved.

[0099] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0100] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0101] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
