Description

Technical Field

[0001] This utility model relates to the field of lifting tools, specifically to a wire cylinder lifting tool. Background Technology

[0002] A conductor drum is a device used to guide, protect, or support conductors or cables. Wires can be neatly arranged on the surface of the conductor drum, facilitating management and maintenance.

[0003] Wire drums with wires wound on their surface are usually quite heavy. During production, when handling wire drums, a lifting device is typically used to hold and move the drum along its circumference. Since the wires are wound on the outside of the drum, to prevent damage to the insulation layer when the cutting tool grips the drum, the drum is usually clamped by rotating around the center hole. The outward expansion pressure of the clamping blocks generates sufficient friction between the clamping blocks and the drum, thus ensuring reliable clamping of the drum by the lifting device.

[0004] However, during the transfer process, due to the large weight of the guide tube, deceleration or sudden stop during the movement will cause the guide tube to shake. Sometimes the shaking amplitude is too large and may even cause the guide tube to fall, affecting the life safety of the surrounding staff. Utility Model Content

[0005] The purpose of this invention is to provide a wire cylinder lifting device that ensures reliable clamping of the wire cylinder.

[0006] To achieve the above objectives, this utility model provides a wire cylinder lifting device, including a lifting device body, a positioning rod, a locking pin, and a locking drive that is driven to connect with the locking pin. The positioning rod is fixedly connected to the lifting device body, and the lifting device body is provided with a through hole. The locking drive drives the locking pin to extend or retract through the through hole.

[0007] The locking pin has two working states: locked and unlocked. When the locking pin retracts from the through hole, it is in the unlocked state; when the locking pin extends from the through hole, it is in the locked state.

[0008] Preferably, at least two locking pins are provided, and multiple locking pins are arranged symmetrically around the circumference of the lifting device body.

[0009] Preferably, the locking drive includes a driver, a drive mechanism connected to the driver, and a slider. The driver is connected to the lifting device body, the lifting device body is provided with a slide groove, the slider slides in the slide groove, one end of the slider is connected to the drive mechanism, and the other end is connected to the locking pin. The driver drives the slider to slide in the slide groove through the drive mechanism.

[0010] Multiple sliders are set, and each slider is set to correspond one-to-one with a locking pin.

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

[0012] Multiple links are configured, and each link corresponds to a slider.

[0013] Preferably, the driver is configured to move horizontally, and the driver pushes the outer edge of the rotating part.

[0014] Preferably, the actuator is a cylinder, and the wire spool lifting device also includes a control handle, on which a first control valve and a second control valve are provided. The first control valve and the second control valve control the extension and retraction of the locking pin, respectively.

[0015] Preferably, the wire drum lifting device also includes a pressure switch for controlling the extension of the cylinder.

[0016] According to the above technical solution, the positioning rod of this utility model, in conjunction with the positioning groove on the guide tube, can determine the relative position of the guide tube lifter and the guide tube. The locking drive action extends the locking pin outward, pushing it into the locking hole on the guide tube. Through the cooperation of the locking pin and the locking hole, the guide tube lifter can reliably clamp the guide tube. If the locking pin is retracted, the guide tube lifter will release the guide tube, thus achieving the effect of separating the guide tube lifter from the guide tube.

[0017] The positioning groove is V-shaped and has a certain depth. During the process of the positioning rod engaging with the positioning groove, the positioning rod can slide down along the side of the V-shaped positioning groove. At the same time, the positioning rod will also slide towards the middle of the V-shaped positioning groove. During this process, the lifting device body will also rotate relative to the guide tube. Meanwhile, the lifting device body gradually approaches the guide tube. As the lifting device body gradually approaches the guide tube, the lower end of the lifting device body will eventually enter the inner cylinder of the guide tube.

[0018] The radius of the lifting device body is slightly smaller than the inner diameter of the guide tube, resulting in a smaller clearance between the two after the lower end of the lifting device body enters the inner tube of the guide tube. Therefore, when the guide tube lifting device lifts the guide tube, the lower end of the lifting device body can provide a certain degree of restraint on the guide tube, ensuring no swaying between the guide tube and the lifting device during movement. Furthermore, the engagement of the locking pin and locking hole ensures that when the guide tube lifting device moves with the guide tube, regardless of whether the device decelerates or stops abruptly, the guide tube maintains a relatively stable position relative to the device and will not detach from it, thus guaranteeing the reliability of the guide tube lifting device's clamping of the guide tube.

[0019] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0037] In this utility model, unless otherwise stated, directional words such as "one end," "the other end," "outer surface," "axis," "conical," and "near" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0038] A wire drum lifting device includes a lifting device body 1, a positioning rod 2, a locking pin 3, and a locking drive that is driven to connect with the locking pin 3. The positioning rod 2 is fixedly connected to the lifting device body 1. The lifting device 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.

[0039] The locking pin 3 has two working states: locked state and unlocked state. When the locking pin 3 is retracted from the through hole 11, the locking pin 3 is in the unlocked state. When the locking pin 3 is extended from the through hole 11, the locking pin 3 is in the locked state.

[0040] By implementing the above technical solution, the positioning rod 2, in conjunction with the positioning groove 61 on the guide tube 6, can determine the relative position of the guide tube lifter and the guide tube 6. The locking drive action extends the locking pin 3 outward, pushing it into the locking hole 62 on the guide tube 6. Through the cooperation of the locking pin 3 and the locking hole 62, the guide tube lifter can reliably clamp the guide tube 6. If the locking pin 3 is retracted, the guide tube lifter will release the guide tube 6, thus achieving the effect of separating the guide tube lifter from the guide tube 6.

[0041] The positioning groove 61 is V-shaped and has a certain depth. During the process of positioning rod 2 cooperating with positioning groove 61, positioning rod 2 can slide down along the side of V-shaped positioning groove 61. At the same time, positioning rod 2 will also slide towards the middle position of V-shaped positioning groove 61. During this process, the lifting device body 1 will rotate relative to the guide tube 6. At the same time, the lifting device body 1 will gradually approach the guide tube 6. During the process of the lifting device body 1 gradually approaching the guide tube 6, the lower end of the lifting device body 1 will eventually enter the inner tube of the guide tube 6.

[0042] The radius of the lifting device body 1 is slightly smaller than the inner diameter of the guide tube 6, resulting in a smaller clearance between the two after the lower end of the lifting device body 1 enters the inner tube of the guide tube 6. Therefore, when the guide tube lifter raises the guide tube 6, the lower end of the lifting device body 1 provides a certain limiting effect on the guide tube 6, ensuring no swaying between the guide tube 6 and the guide tube lifter during movement. Furthermore, the engagement of the locking pin 3 and the locking hole 62 prevents relative rotation between the guide tube 6 and the guide tube lifter. When the guide tube lifter moves with the guide tube 6, regardless of whether the guide tube lifter decelerates or stops abruptly, the guide tube 6 maintains a relatively stable position relative to the guide tube lifter and will not detach from it, thus ensuring the reliability of the guide tube lifter's clamping of the guide tube 6.

[0043] In this embodiment, preferably, at least two locking pins 3 are provided, and multiple locking pins 3 are arranged symmetrically around the circumference of the lifting device body 1.

[0044] Multiple locking pins 3 are symmetrically arranged around the circumference of the lifting device body 1. When the lifting device clamps the wire cylinder 6 and completes the lifting action of the wire cylinder 6, the multiple evenly arranged locking pins 3 can provide uniform and reliable support for the wire cylinder 6, ensuring the relative stability between the wire cylinder 6 and the lifting device, and avoiding frequent shaking or tilting of the wire cylinder 6 during the movement of the wire cylinder 6.

[0045] Preferably, multiple locking pins 3 operate simultaneously, allowing them to extend or retract at the same time, thus achieving reliable locking and unlocking of the wire tube 6.

[0046] Preferably, the locking pin 3 and the positioning rod 2 are arranged in a one-to-one correspondence, with one positioning rod 2 and one locking pin 3 located on the same vertical line. During the engagement of the positioning rod 2 and the positioning groove 61, the locking pin 3 will also rotate with the positioning rod 2 to the position corresponding to the locking hole 62. By setting the front end of the locking hole 62 to have a larger diameter, the larger diameter can guide the locking pin 3. Under the combined guiding effect of the locking hole 62 and the V-shaped positioning groove 61, the locking pin 3 can more easily enter the locking hole 62, which can significantly improve the success rate of the engagement between the locking pin 3 and the locking hole 62.

[0047] Moreover, by improving the success rate of the engagement between the locking pin 3 and the locking hole 62 in this way, the engagement gap between the locking pin 3 and the locking hole 62 can also be set to be smaller, thereby avoiding large-scale shaking between the wire drum lifter and the wire drum 6 during the movement process after the wire drum lifter and the wire drum 6 are engaged, thus reliably reducing the dynamic load during the operation of the wire drum lifter.

[0048] In this embodiment, preferably, the locking drive includes a driver, a drive mechanism connected to the driver, and a slider. The driver is connected to the lifting device body 1. The lifting device body 1 is provided with a slide groove 12. The slider slides in the slide groove 12. One end of the slider is connected to the drive mechanism, and the other end is connected to the locking pin 3. The driver drives the slider to slide in the slide groove 12 through the drive mechanism.

[0049] One end of the slider is slidably engaged with the slide groove 12. Under the action of the driver, the slider can reciprocate along the length of the slide groove 12, thereby realizing the extension and retraction of the locking pin 3 located at the other end of the slider.

[0050] Preferably, the slide groove 12 is arranged along the diameter direction of the lifting device body 1, so that when the slider moves, it will move along the diameter direction of the lifting device body 1, and the locking pin 3 will also extend or retract along the diameter direction of the lifting device body 1. At the same time, the locking hole 62 is arranged along the diameter direction of the guide tube 6, so that the locking hole 62 can easily cooperate with the locking pin 3.

[0051] Multiple sliders are provided, and each slider corresponds to a locking pin 3. Preferably, the drive mechanism acts on multiple sliders simultaneously, enabling the sliders to move synchronously, thereby achieving the purpose of simultaneously extending or retracting multiple locking pins 3.

[0052] In one embodiment, two sliders are provided, and the corresponding grooves 12 of the two sliders are located on the same diameter of the lifting device body 1. The driver is a rotatable structure such as a motor, and the driver is connected to the lead screw through a transmission structure, enabling the driver to drive the lead screw to rotate. Two nuts are respectively fitted at both ends of the lead screw, and the slider is sleeved on the outside of the nut and fixedly connected to the nut. Through the cooperation between the slider and the groove 12, the nut cannot rotate. Therefore, when the lead screw rotates, the nut will drive the slider to move linearly along the lead screw. When the driver drives the lead screw to rotate, the nuts at both ends of the lead screw will move closer or further away from each other, thereby causing the locking pin 3 to extend or retract synchronously.

[0053] Preferably, the slider and the locking pin 3 are integrated into one structure. When the lead screw rotates, the two nuts at both ends of the lead screw can move closer to each other or move further away from each other at the same time, so that the two locking pins 3 that are fixedly connected to the nuts can extend or retract synchronously.

[0054] 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. The driver drives the rotating member 42 to rotate.

[0055] Multiple links 43 are configured, and each link 43 corresponds to a slider.

[0056] When there are more than two locking pins 3, the drive mechanism using the rotating part 42 and the connecting rod 43 can achieve the effect of driving multiple sliders simultaneously.

[0057] The rotation center of the rotating component 42 coincides with the axis of the lifting device body 1, thus allowing the rotating component 42 to rotate around the axis of the lifting device body 1. The connecting rod 43 is connected to the outer edge of the rotating component 42. When the locking pin 3 is in the locked state, the connecting rod 43 and the slider are on the same straight line, with an included angle of 180°, causing the locking pin 3 at the other end of the slider to be at its furthest point from the rotating component 42. Subsequently, as the rotating component 42 rotates, the included angle between the connecting rod 43 and the slider gradually decreases, and the connecting rod 43 pulls the slider towards the rotating component 42. The distance between the slider and the outer edge of the rotating component 42 also gradually decreases, and the locking pin 3 gradually retracts. Therefore, during the rotation of the rotating component 42, the locking pin 3 switches from a locked state to an unlocked state.

[0058] Multiple connecting rods 43 are configured, each corresponding to a slider. These connecting rods 43 are arranged symmetrically along the circumference of the rotating component 42. When the locking pin 3 is in the locked state, the connecting rod 43 and the slider are on the same straight line; when the locking pin 3 is in the unlocked state, the angle between the connecting rod 43 and the slider is minimized.

[0059] Preferably, the slider and the locking pin 3 are integrated into one structure, and the connecting rod 43 is connected to the integrated structure through a rotating shaft. During the rotation of the rotating part 42, the connecting rod 43 pushes or pulls the integrated structure to extend or retract through the rotating shaft.

[0060] In this embodiment, preferably, the actuator is configured to move horizontally, and the actuator pushes the outer edge of the rotating member 42.

[0061] The drive is set to move horizontally, which reduces the height of the wire guide pipe hanger and prevents the wire guide pipe 6 from taking up more vertical space.

[0062] The actuator is configured as a linear motion mechanism such as a cylinder 44, which can drive the rotating component 42 to rotate via the drive rod 45. When the actuator drives the rotating component 42, in order to ensure a reliable connection between the drive rod 45 and the actuator, the actuator is rotatably connected to the lifting device body 1.

[0063] The driver pushes the edge of the rotating part 42, so that the driver only needs a small extension stroke to obtain a sufficiently large rotation angle of the rotating part 42.

[0064] In this embodiment, preferably, the actuator is a cylinder 44, and the wire drum lifting device also includes a control handle, on which a first control valve 51 and a second control valve 52 are provided. The first control valve 51 and the second control valve 52 respectively control the extension and retraction of the locking pin 3.

[0065] By controlling the gas to enter the cylinder 44 from different ends, the extension and retraction of the cylinder 44 telescopic rod can be controlled.

[0066] The first control valve 51 and the second control valve 52 control the two air intake pipes respectively. The two air intake pipes are connected to the two ends of the cylinder 44 respectively. By controlling the air intake through different air intake pipes, the extension rod of the cylinder 44 can be extended or retracted.

[0067] Preferably, when the telescopic rod of cylinder 44 is retracted to its maximum position, the locking pin 3 is in a locked state. Since the piston is already at the bottom of cylinder 44 at this time, the external force on the locking pin 3 is unlikely to pull the piston out of cylinder 44, thus avoiding the problem of locking failure caused by external force driving the piston to move.

[0068] In this embodiment, preferably, the wire cylinder hanger also includes a pressure switch for controlling the extension of the cylinder 44.

[0069] The pressure switch is located in the air intake pipe that supplies air to the rear end of cylinder 44, and is positioned in front of the second control valve 52.

[0070] The pressure switch is equipped with a release button 54 and a preset pressure value. A pressure sensor is installed on the wire guide drum hanger to detect the actual load on the hanger. When the actual load is less than the preset pressure value of the pressure switch, and the release button 54 is pressed, the air circuit on the pressure switch is connected, and the air inlet pipe containing the second control valve 52 is connected to the compressed air source. At this time, 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. After the telescopic rod of the cylinder 44 extends, it drives the drive mechanism, retracting the locking pin 3 and switching it from the locked state to the unlocked state.

[0071] Therefore, in actual production, when the operator lowers the wire drum 6, the pressure sensor on the wire drum hanger will detect that the load on the wire drum hanger is less than the set value. At this time, the operator will press the release button 54, and the air circuit of the pressure switch will be connected. Then, the operator can press the second control valve 52 on the control handle to retract the locking pin 3, so that the wire drum hanger is separated from the wire drum 6.

[0072] If the operator accidentally presses the release button 54 while the wire guide drum 6 is still suspended below the wire guide drum lifting device, the pressure sensor will detect that the load on the wire guide drum lifting device is still greater than the set value. Therefore, the air circuit of the pressure switch will not be connected, and 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 guide drum 6 will not be released.

[0073] By setting a pressure switch, the release of the guide drum 6 by the guide drum lifter is made more reliable, which can effectively prevent the guide drum 6 from being released at an inappropriate time due to misoperation of the guide drum lifter.

However, the present invention is not limited to the specific details of the above embodiments.
