Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker crane technology, and in particular to a wire rope strand detection device. Background Technology
[0002] During the lifting and lowering process of a stacker crane, the wire rope is repeatedly wound on the lifting drum. Over time, the wire rope will first develop burrs, and eventually break due to unraveling. Traditional stacker cranes do not have an effective way to detect unraveling of the wire rope, and problems are mainly discovered by manual visual inspection or periodic maintenance. This makes it very easy for the wire rope to break due to unraveling, causing the goods carried by the stacker crane to fall. Utility Model Content
[0003] This invention provides a wire rope strand unraveling detection device, which aims to solve the problem that there is a lack of related devices in the prior art for real-time monitoring of wire rope strand unraveling.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model embodiment provides a wire rope strand unraveling detection device, including:
[0006] A strand receiving component is used to transmit the force generated when strands of a wire rope become loose.
[0007] The guide component is fixedly connected to the strand receiving component;
[0008] Mounting base, the guide member passes through the mounting base and is connected to the limiting plate, the limiting plate is provided with a monitoring rod;
[0009] A strand detector is fixedly mounted on the mounting base and is used to detect changes in the position of the monitoring rod.
[0010] In one embodiment, a first through hole is provided through the mounting base, and the guide member is slidably disposed in the first through hole; a compression spring is sleeved on the guide member, and the compression spring abuts against the loose strand receiving member and the mounting base respectively.
[0011] In one embodiment, two guide members are provided, and two first through holes are provided on the mounting base.

[0037] Please see Figure 1-4 This utility model provides a wire rope strand unraveling detection device, comprising:
[0038] 1, a strand receiving component, is used to transmit the force generated when the wire rope strands become loose;
[0039] Guide component 2 is fixedly connected to the strand receiving component 1;
[0040] Mounting base 3, the guide 2 passes through the mounting base 3 and is connected to the limiting piece 4, the limiting piece 4 is provided with a monitoring rod 5 arranged parallel to the guide 2;
[0041] The strand detector 6 is fixedly mounted on the mounting base 3 and is used to detect changes in the position of the monitoring rod 5.
[0042] Figure 1 This is a scene illustration illustrating the practical application of the wire rope strand unraveling detection device described in this application. Figure 1 and Figure 2 As shown, the lifting motor 7 drives the lifting drum 71 to rotate. A lifting wire rope 72 is wound on the lifting drum 71. By rotating the lifting drum 71, the lifting wire rope 72 can be wound around the lifting drum 71 or unwound from the lifting drum 71, thereby realizing the lifting and lowering of the stacker crane.
[0043] In practical use, the length direction of the loose strand receiving component 1 is parallel to the axial direction of the lifting drum 71, and the loose strand receiving component 1 is in contact with several turns of lifting wire rope 72 wound on the lifting drum 71.
[0044] Under normal operating conditions, the lifting wire rope 72 will be wound around the lifting drum 71, and the loose strand receiving part 1 will be in contact with several turns of the lifting wire rope 72 wound around the lifting drum 71; at this time, the position of the monitoring rod 5 will not change, and the loose strand detector 6 will not detect the change in the position of the monitoring rod 5.
[0045] When the wire rope becomes unraveled, the unraveled strands on the lifting wire rope 72 act on the unraveled strand receiving component 1, causing a change in the position of the receiving component 1. This movement of the receiving component 1 then moves the guide component 2, which in turn moves the limiting plate 4. The limiting plate 4 then moves the monitoring rod 5, resulting in a change in the position of the monitoring rod 5. The unraveled strand detector 6 detects this change and feeds the information back to the stacker crane control system, indicating a wire rope unraveling and triggering an alarm, thus providing an alarm function to indicate wire rope unraveling failure. Furthermore, this application uses the mounting base 3 as a base, facilitating the installation of the entire wire rope unraveling detection device.
[0046] In one embodiment, the loose strand receiving member 1 includes a roller support 11, on which a rope pressing roller 12 is rotatably disposed.
[0047] The rope pressing roller 12 is in contact with several turns of lifting wire rope 72 wound on the lifting drum 71. When the wire rope moves, the rope pressing roller 12 can rotate at the same time, thereby reducing the friction force on the rope pressing roller 12.
[0048] In one embodiment, the roller support 11 includes a main board 111 and side plates 112 disposed at both ends of the main board 111. A rotating shaft 113 is connected to the side plates 112 at both ends, and the rope pressing roller 12 is rotatably disposed on the rotating shaft 113 via bearings.
[0049] The rope pressing roller 12 is mounted on the rotating shaft 113, which facilitates the contact between the rope pressing roller 12 and the lifting wire rope 72 wound around the lifting drum 71.
[0050] In a further embodiment, a first through hole 31 is provided through the mounting base 3, and the guide member 2 is slidably disposed in the first through hole 31; a compression spring 21 is sleeved on the guide member 2, and the compression spring 21 abuts against the loose strand receiving member 1 and the mounting base 3 respectively.
[0051] Specifically, the guide member 2 is fixedly connected to the main board 111, and the guide member 2 and the side plate 112 are fixedly connected to both sides of the main board 111 respectively. In this embodiment, the guide member 2 and the side plate 112 are both perpendicular to the main board 111.
[0052] Under the action of the compression spring 21, the main board 111 can be continuously pushed to move towards the lifting drum 71, so that the rope pressing roller 12 can keep in close contact with the lifting wire rope 72 wound on the lifting drum 71; at the same time, when the wire rope strands are loose, it does not affect the loose wire rope acting on the rope pressing roller 12, so that the guide 2 moves and drives the monitoring rod 5 to move.
[0053] In a further embodiment, two guide members 2 are provided, and two first through holes 31 are provided on the mounting base 3. The two guide members 2 are slidably disposed in the two first through holes 31 respectively; the ends of the two guide members 2 away from the loose strand receiving member 1 are connected to the same limiting piece 4.
[0054] Specifically, two guide members 2 are set at both ends of the main board 111 along its length, and two through holes on the mounting base 3 are also set at both ends of the mounting base 3 along its length. Compression springs 21 are provided on both guide members 2.
[0055] The two guide members 2 enable the guide members 2 to slide more stably within the mounting base 3, and under the simultaneous action of the two compression springs 21, the rope pressing roller 12 can maintain a more stable contact with the lifting drum 71, ensuring that the rope pressing roller 12 can react more sensitively when the wire rope strands come loose.
[0056] In one embodiment, the mounting base 3 has protrusions 32 at both ends, and the two first through holes 31 are respectively provided on the two protrusions 32; the strand detector 6 is provided on the mounting base 3 and is located between the two protrusions 32.
[0057] Between the two protrusions 32, an inwardly recessed groove 33 is formed on the mounting base 3. The loose strand detector 6 is fixedly installed in the groove 33, making the whole structure more compact and easier to assemble. In addition, during the operation of the stacker crane, even if a heavy object is accidentally dropped, it is not easy to hit the loose strand detector 6; during transportation, it is not easy to cause the loose strand detector 6 to be crushed.
[0058] In a further embodiment, a limiting hole 41 is provided through the limiting piece 4, and the monitoring rod 5 is disposed in the limiting hole 41.
[0059] The monitoring rod 5 is installed within the limiting hole 41 for easy installation. In this embodiment, to facilitate adjustment of the position of the monitoring rod 5 and enable the strand breakage detector 6 to detect wire rope unraveling more sensitively, the monitoring rod 5 is threadedly connected to the limiting hole 41. This allows the monitoring rod 5 to be adjusted in position within the limiting hole 41 by rotating it, thus shortening the distance between the monitoring rod 5 and the strand breakage detector 6. This ensures that the strand breakage detector 6 can detect any positional change of the monitoring rod 5 more quickly, identifying wire rope unraveling immediately and triggering an alarm, thereby ensuring production safety.
[0060] In one embodiment, the mounting base 3 is provided with a plurality of mounting holes 34 perpendicular to the axial direction of the first through hole 31.
[0061] The mounting holes 34 facilitate the fixed connection between the mounting base 3 and the stacker crane in this application, and also facilitate the installation of the wire rope strand detection device in this application. In this embodiment, four mounting holes 34 are provided, divided into two groups, with two mounting holes 34 in each group respectively located on both sides of the first through hole 31.
[0062] In a further embodiment, the strand breakage detector 6 is a proximity switch. When the position of the monitoring rod 5 approaches the strand breakage detector 6, the change in position of the monitoring rod 5 can be detected, thereby detecting the strand breakage of the wire rope.
[0063] The working principle of this application is as follows, which is divided into normal working state and scattered stock detection state.
[0064] Normal operating condition: The lifting wire rope 72 will be wound around the lifting drum 71. The rope pressing roller 12 is in contact with several turns of the lifting wire rope 72 wound around the lifting drum 71. The stacker is working normally. The lifting wire rope 72 is normally wound around the rope pressing roller 12. At this time, the position of the monitoring rod 5 will not change, and the loose strand detector 6 will not detect the change in the position of the monitoring rod 5.
[0065] When a strand breaks off, the strands on the lifting wire rope 72 act on the rope pressing roller 12, causing a change in the position of the rope pressing roller 12. The rope pressing roller 12 transmits this information to the roller support 11, which in turn causes the guide 2 to change position. The guide 2 then moves the limit plate 4, which in turn moves the monitoring rod 5, causing a change in the position of the monitoring rod 5. The strand break detector 6 detects this change in the position of the monitoring rod 5 and feeds the information back to the stacker crane control system, triggering a wire rope strand break alarm and thus providing an alarm function to indicate wire rope strand breakage.
[0066] This application, through the aforementioned structure, can detect changes in the strands of the wire rope in real time, prevent the possibility of wire rope breakage in advance, and effectively prevent goods from falling from the stacker crane.
[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
