Description

Technical Field

[0001] The present invention relates to the field of traction technology, in particular to an automatic safety rope-arranging mechanism for lifting equipment. Background Art

[0002] The rope-guiding mechanism is a crucial component of traction equipment. Its function is to guide the wire rope to wind sequentially around the drum. During use, the screw must rotate in the correct direction, and the movement of the rope-guiding mechanism must be consistent with the direction of the reversing frame's deviation. Otherwise, the rope-guiding mechanism will not be able to reverse normally.

[0003] At present, when the rope of the rope-arranging mechanism is subjected to oblique tension, the cable or steel belt is easily worn and broken, and the lead screw of the rope-arranging mechanism sometimes cannot be rotated correctly and in time, which causes the cable to remain in an oblique tension state for a long time, causing wear of the cable, and in severe cases, it may cause the cable to break, and the movement of the cable will accelerate the wear. However, the existing ropes are generally only inspected periodically, and the inspection generally requires all ropes to be released. The steel wire rope is detected non-contact by sensors, while the cables are generally checked manually with the naked eye, which is more troublesome. In addition, the existing ropes cannot be effectively dynamically detected during work, and there are certain safety hazards. Therefore, a rope-arranging mechanism is needed to solve the problem. Summary of the Invention

[0021] The following is combined with Figures 1-6 The present invention is described in further detail.

[0022] An embodiment of the present invention discloses an automatic safety rope-arranging mechanism for lifting equipment.

[0023] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Reference Figures 1-6 , an automatic safety rope-arranging mechanism for lifting equipment, comprising: The track base 1 has a connecting plate 11 fixedly connected to its top, and a first stand 12 and a second stand 13 fixedly connected to the top of the connecting plate 11. Figure 1 As shown, the track base 1 adopts double tracks, which effectively improves the stability and load-bearing capacity of the rope arrangement mechanism; A rope winding module 2, which is detachably connected to the second stand 13 and is used for retracting and releasing the rope; The driving module 3 is detachably connected to the first stand 12 and controls the movement of the protective shell 4 to reduce the inclined angle of the rope, thereby reducing the wear of the rope; A protective shell 4 is provided on the driving module 3 and a rope arrangement mechanism is provided in the protective shell 4; The stand 5 is detachably connected to the drive module 3 and is disposed inside the protective shell 4. A dynamic visual detection mechanism is disposed outside the stand 5 and moves synchronously with the rope arrangement mechanism. The dynamic visual detection mechanism performs a surrounding detection of the rope in the working state. The detection cylinder 6 is fixedly connected to the driving module 3 and a Dou element sensor 61 is provided in the detection cylinder 6; The buffer anti-fall mechanism 7 is arranged inside the detection tube 6 and is used to clamp the rope to prevent it from falling after receiving the wear signal transmitted by the dynamic visual detection mechanism and the Dou element sensor 61.

[0025] Specifically, during normal use, the rope winding module 2 controls the rope retraction and release, and cooperates with the rope arranging mechanism to achieve the lifting effect of the rope. During operation, the rope passes through the dynamic visual detection mechanism, which performs a surrounding detection on the rope to avoid missing possible wear and tear on the rope surface. When performing the detection, it is necessary to analyze and use it according to the material of the rope. When the rope is a cable or hemp rope, the dynamic visual detection mechanism performs a surrounding detection on its surface, and when severe wear and tear is observed, it sends a signal. After receiving the signal, the buffering and anti-fall mechanism 7 clamps the rope. At the same time, the rope winding module 2 stops working and waits for the staff to inspect and maintain it. When the rope is a steel belt or steel wire, the dynamic visual detection mechanism and the Dou element sensor 61 work synchronously. Among them, the Dou element sensor 61 is based on the principle of "spatial magnetic field vector synthesis" and judges its damage status by detecting changes in the magnetic field around the wire rope. Both the dynamic visual detection mechanism and the Dou element sensor 61 do not need to directly contact the wire rope to complete the detection, thereby reducing interference with the rope and ensuring the normal operation of the rope.

[0026] Compared with the existing technology, the present application uses a dynamic detection method that combines a dynamic visual detection mechanism and a Dou element sensor 61 to perform real-time detection of the wear and operating status of the rope during operation, and the 360° no-dead-angle detection of the dynamic visual detection mechanism further ensures the comprehensiveness of the detection, avoiding missing the worn parts of the rope and causing losses. During regular inspections, there is no need for excessive manual operation, reducing the burden on workers.

[0027] Reference Figures 1-4 Specifically, in the embodiment of the present invention, the rope-laying mechanism includes a servo motor 41, a pulley group 42 and a guide rope pulley 43. The servo motor 41 is fixedly connected to the outer wall of the protective shell 4, and its output shaft is coaxially fixedly connected to one of the pulleys of the pulley group 42. The pulley group 42 is arranged on the inner side of the protective shell 4 and is rotatably connected to the inner wall of the protective shell 4. The center of the guide rope pulley 43 is coaxially fixedly connected to a shaft, and the shaft is rotatably connected to the inner wall of the protective shell 4.

[0028] In the embodiment of the present invention, the rope first passes through the pulley group 42 below, passes through the guide pulley 43, and then passes vertically downward through the detection cylinder 6 for traction. During normal use, other structures in the detection cylinder 6 do not contact the rope, ensuring smooth traction of the rope. It should be noted that the pulley group 42 is composed of multiple pulleys of different sizes, and the highest pulley is flush with the guide pulley 43 to avoid contact between the rope and the worm gear 51.

[0029] Reference Figure 1Specifically, in an embodiment of the present invention, the rope winding module 2 includes a traction motor 21 and a rope drum 22. The traction motor 21 is fixedly connected to the second vertical frame 13, the rope drum 22 is rotatably connected to the second vertical frame 13, and the output shaft of the traction motor 21 is coaxially fixedly connected to the rope drum 22.

[0030] In the embodiment of the present invention, when in use, the traction motor 21 is started to control the rotation direction of the rope drum 22, thereby controlling the rope retraction and release of the rope drum 22.

[0031] Reference Figures 1-4 Specifically, in the embodiment of the present invention, the driving module 3 includes a rope-arranging motor 31 and a screw rod 32. The rope-arranging motor 31 is fixedly connected to the outer wall of the first frame 12. The output shaft of the first frame 12 is coaxially fixedly connected to the screw rod 32. A limiting guide rod 33 is fixedly connected to the first frame 12. One end of the screw rod 32 is rotatably connected to the inner wall of the first frame 12. A slider 34 is provided on the outer sliding sleeve of the screw rod 32 and the limiting guide rod 33. The protective shell 4 is fixedly connected to the top of the slider 34.

[0032] In the embodiment of the present invention, when in use, the rope-arranging motor 31 is started to control the rotation direction of the screw rod 32, thereby controlling the moving direction of the slider 34, and then controlling the moving direction of the protective shell 4, wherein the limiting guide rod 33 supports the slider 34 and also limits the movement of the slider 34 so that it can only move horizontally. It should be noted that the movement of the slider 34 is synchronized with the retraction and release of the rope, so that the rope oblique pulling angle is always less than 3°.

[0033] Reference Figure 5 Specifically, in the embodiment of the present invention, the dynamic visual detection mechanism includes a worm wheel 51 and a worm 52. A connecting ring is fixedly extended from the inner wall of the worm wheel 51, and an annular groove is provided on the connecting ring. A protrusion that is rotatably engaged with the annular groove is provided on the stand 5. Both ends of the worm 52 are rotatably connected to the inner wall of the protective shell 4. The worm 52 is meshed with the worm wheel 51 for transmission. A pulley group 53 is connected between the worm 52 and the shaft. The camera 54 is embedded in the inner surface of the worm wheel 51. The middle part of the worm wheel 51 is hollowed out, and the highest point of the guide pulley 43 is lower than the highest point of the hollowed-out area of the worm wheel 51.

[0034] In the embodiment of the present invention, when dynamic detection is performed, the rope moves, driving the guide pulley 43 to rotate synchronously. At the same time, the shaft of the guide pulley 43 rotates, driving the pulley group 53 to work, and the pulley group 53 drives the worm 52 to rotate. The worm 52 engages with the worm wheel 51 for transmission, so that the worm wheel 51 rotates synchronously with the movement of the rope, and then performs all-round dynamic detection of the outside of the rope without dead angles, ensuring the safety of the rope when working, and when serious wear is detected, a signal can be sent to the buffer anti-fall mechanism 7 at the first time to stop the rope and avoid accidents.

[0035] Reference Figures 1-6 Specifically, in the embodiment of the present invention, the buffering and anti-falling mechanism 7 includes a guide rail 71, a rotating plate 72 is rotatably connected to the middle part of the guide rail 71, a sliding plate 73 is slidably connected to the guide rail 71, a connecting rod 74 is movably connected between the rotating plate 72 and the sliding plate 73, a vertical plate 75 is fixedly connected to one side of the sliding plate 73, and a plurality of horizontal clamping plates 76 are fixedly connected to the surface of one side of the sliding plate 73, wherein a motor (existing technology, not shown in the figure) for controlling the rotation of the rotating plate 72 is provided on the guide rail 71.

[0036] In an embodiment of the present invention, when receiving a signal to stop the rope, the motor works, driving the rotating plate 72 to rotate and at the same time driving the sliding plate 73 to slide through the connecting rod 74, approaching each other, thereby making the vertical plates 75 approach each other, and the horizontal clamping plates 76 approach each other to clamp the rope, slowing down the descent speed of the rope until the rope is stopped. It should be noted that the stop signal is sent to the traction motor 21 and the rope-arranging motor 31 at the same time, pausing synchronously, waiting for maintenance confirmation by the staff, wherein the setting of multiple horizontal clamping plates 76 provides multi-point clamping, thereby improving the clamping and stopping capability.

[0037] Reference Figure 3 Specifically, in the embodiment of the present invention, the detection cylinder 6 is located directly below the guide rope wheel 43, and the edge of the detection cylinder 6 is rounded.

[0038] In the embodiment of the present invention, the rope is ensured to pass through the center of the detection cylinder 6 accurately without contacting other structures in the detection cylinder 6, and the edges are smoothed to ensure that even if the rope contacts the edge of the detection cylinder 6, it will not be excessively worn.

[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
