DETAILED DESCRIPTION

[0032] The following is combined with Figures 1-6 The present invention is described in further detail.

[0033] An embodiment of the present invention discloses an automatic safety rope-arranging mechanism for lifting equipment.

[0034] 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.

[0035] Reference Figures 1-6 , an automatic safety rope-arranging mechanism for lifting equipment, comprising:

[0036] 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;

[0037] A rope winding module 2, which is detachably connected to the second stand 13 and is used for retracting and releasing the rope;

[0038] 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;

[0039] A protective shell 4 is provided on the driving module 3 and a rope arrangement mechanism is provided in the protective shell 4;

[0040] 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.

[0041] 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;

[0042] 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.

[0043] Specifically, in normal use, the rope winding module 2 controls the winding and unwinding of the rope, and cooperates with the rope arranging mechanism to complete the lifting effect of the rope. In the running process, the rope passes through the dynamic visual detection mechanism, and the dynamic visual detection mechanism performs around detection on the rope to avoid missing the wear on the surface of the rope. When detecting, the material of the rope needs to be analyzed and used. When the rope is a cable or a hemp rope, the dynamic visual detection mechanism performs around detection on the surface thereof, and when a serious wear is observed, a signal is sent. The buffer anti-falling mechanism 7 receives the signal, clamps the rope, and the rope winding module 2 stops working, waiting for the worker to repair and maintain. When the rope is a steel band or a steel wire, the dynamic visual detection mechanism and the Duffing element sensor 61 work synchronously. The Duffing element sensor 61 judges the damage state of the steel wire rope based on the principle of "space magnetic field vector synthesis" by detecting the change of the magnetic field around the steel wire rope. Neither the dynamic visual detection mechanism nor the Duffing element sensor 61 needs to directly contact the steel wire rope to complete the detection, reduces the interference to the rope, and ensures the normal operation of the rope.

[0044] Compared with the prior art, the dynamic detection mode combining the dynamic visual detection mechanism and the Duffing element sensor 61 is used to detect the wear and running state of the rope in real time. The 360° dead angle-free detection of the dynamic visual detection mechanism further ensures the comprehensiveness of the detection, avoids missing the wear of the rope, and causes loss. In the periodic detection, no excessive manual operation is needed, and the burden of the worker is reduced.

[0045] Referring to Figures 1-4 Specifically, in the embodiment of the application, the rope arranging mechanism comprises a servo motor 41, a pulley block 42 and a rope guide wheel 43. The servo motor 41 is fixedly connected to the outer wall of the protection shell 4, and the output shaft thereof is coaxially fixedly connected to one of the pulleys of the pulley block 42. The pulley block 42 is arranged on the inner side of the protection shell 4 and is rotatably connected to the inner wall of the protection shell 4. The rope guide wheel 43 is coaxially fixedly connected with a shaft rod at the center thereof, and the shaft rod is rotatably connected to the inner wall of the protection shell 4.

[0046] In the embodiment of the application, the rope passes through the rope guide wheel 43 vertically downward from the pulley block 42 below and passes through the detection cylinder 6 for traction. In normal use, the other structures in the detection cylinder 6 do not contact the rope, so as to ensure smooth traction of the rope. It should be noted that the pulley block 42 is composed of a plurality of pulleys with different sizes, and the position of the highest pulley is flush with the rope guide wheel 43, so as to avoid the contact between the rope and the worm gear 51.

[0050] In use, the movement direction of the sliding block 34 is controlled by starting the rope arranging motor 31 to control the rotation direction of the lead screw 32, and then the movement direction of the protective shell 4 is controlled, wherein the limiting guide rod 33 supports and limits the movement of the sliding block 34, so that the sliding block 34 can only move horizontally, and it should be noted that the movement of the sliding block 34 is synchronized with the winding and unwinding of the rope, so that the rope inclination angle is always less than 3°.

[0051] With reference to Figure 5 Specifically, in the embodiment of the present application, the dynamic visual detection mechanism comprises a worm gear 51 and a worm 52, the inner wall of the worm gear 51 is fixedly extended with a connecting ring, an annular groove is formed in the connecting ring, a protrusion rotationally connected with the annular groove is arranged on the stand 5, the worm 52 is rotationally connected with the inner wall of the protective shell 4 at both ends, the worm 52 is in meshing transmission with the worm gear 51, a belt pulley set 53 is connected between the worm 52 and the shaft rod, a camera 54 is embeddedly installed on the inner side surface of the worm gear 51, the worm gear 51 is hollowed in the middle, and the highest point of the guide rope wheel 43 is lower than the highest point of the hollowed area of the worm gear 51.

[0052] In dynamic detection, the rope moves to drive the guide rope wheel 43 to rotate synchronously, the shaft rod of the guide rope wheel 43 rotates to drive the belt pulley set 53 to work, the belt pulley set 53 drives the worm 52 to rotate, the worm 52 is in meshing transmission with the worm gear 51, so that the worm gear 51 rotates synchronously with the movement of the rope, and then the rope outside is detected in all directions without dead angle, the safety of the rope during work is ensured, and the rope can be stopped in the first time to send a signal to the buffer anti-falling mechanism 7 when serious wear is detected, so as to avoid accidents.

[0054] In the embodiment of the present application, when the signal of stopping the rope is received, the motor works to drive the rotating plate 72 to rotate and simultaneously drive the sliding plate 73 to slide through the connecting rod 74, so that the vertical plates 75 are close to each other and the horizontal clamping plates 76 are close to each other to clamp the rope, thereby slowing down the descending speed of the rope until the rope is stopped. It should be noted that the stopping signal is sent to the traction motor 21 and the rope arranging motor 31 at the same time, and they are stopped synchronously to wait for the maintenance confirmation of the staff.
