Description

Technical Field

[0001] This utility model relates to the field of cathode plate hoisting technology, specifically to a rope adjustment device for a cathode plate crane. Background Technology

[0002] In industries such as electrolytic metals and non-ferrous metal smelting, cathode plates are crucial production components, and their hoisting is an indispensable part of the production process. However, in the existing crane hoisting process, due to the large number, heavy weight, and irregular shapes of cathode plates, it is difficult to ensure their uniform distribution on the lifting device when hoisting multiple cathode plates simultaneously. This uneven distribution directly causes the lifting device to sway at the moment of hoisting, as the resultant force point of the gravity lines acting on each cathode plate deviates from the geometric center of the lifting device.

[0003] The swaying of the lifting equipment not only increases the difficulty and risk of lifting operations, but may also damage the cathode plate itself, such as causing edge wear, deformation, or even breakage. In addition, swaying may also affect the stability and safety of the crane, and in severe cases, may even lead to safety accidents.

[0004] Therefore, a rope adjustment device for cathode plate cranes is needed to overcome the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a rope adjustment device for a cathode plate crane, thereby achieving the objective of resolving the issues raised in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rope adjustment device for a cathode plate crane, comprising a running trolley, wherein a lifting assembly for lifting the lifting device is provided on the running trolley, and an adjustment assembly is provided on the lifting assembly;

[0007] The lifting assembly includes a winding mechanism mounted on the trolley, a fixed pulley block mounted on the trolley, and a lifting rope mounted on the winding mechanism and connected to the fixed pulley block.

[0008] The adjustment assembly includes two symmetrically arranged bases, a balance arm rotatably mounted on the bases, a connecting block 1 hinged to one end of the balance arm and fixedly connected to the suspension rope, a connecting block 2 hinged to the other end of the balance arm, and a connecting rope fixedly connected between the two connecting blocks 2.

[0009] As a further improvement to the above technical solution:

[0010] The connecting rope is equipped with an adjustment component 2 for adjusting the distance between the two connecting blocks 2.

[0011] The connecting rope is broken at the middle position, and the second adjustment component includes two connecting ends fixedly connected at the broken position of the connecting rope, a screw rod rotatably set on the connecting ends, and a connecting rod threaded between the two screw rods.

[0012] The winding mechanism includes a drum rotatably mounted on a running trolley and a geared motor mounted on the running trolley to drive the drum to rotate. Both ends of the lifting rope are fixedly connected to the drum.

[0013] The trolley is equipped with a rope-pressing assembly for pressing the hoisting rope onto the drum.

[0014] The rope pressing assembly includes a connecting seat 1 fixedly connected to the running trolley, a connecting seat 2 fixedly connected to the connecting seat 1, and a rope pressing roller rotatably mounted on the connecting seat 2.

[0015] The first and second connecting seats are respectively provided with perpendicular waist holes, and the first and second connecting seats are fixedly connected by bolts passing through the waist holes.

[0016] The beneficial effects of this utility model embodiment are as follows:

[0017] In actual use, the lifting device and the cathode plate are connected. When the winding mechanism lifts the cathode plate by winding the lifting rope, when one of the balance arms is under greater force, since the length of the lifting rope is fixed, the rope can be slightly stretched, causing it to rotate slightly toward the side of connecting block one. This, in turn, pulls the other balance arm toward the side of connecting block two through the connecting rope, causing the two balance arms to swing in a cycle. That is, the balance of the lifting device is adjusted by the multiple slight rotations of the balance arms, so that when the lifting device shakes, it can be quickly adjusted to a balanced state.

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] See Figures 1 to 5 This utility model discloses a rope adjustment device for a cathode plate crane, including a running trolley 1, a lifting assembly 10 for lifting the lifting device on the running trolley 1, and an adjustment assembly 12 on the lifting assembly 10;

[0031] The lifting assembly 10 includes a winding mechanism 101 mounted on the running trolley 1, a fixed pulley group 102 mounted on the running trolley 1, and a lifting rope mounted on the winding mechanism 101 and connected to the fixed pulley group 102.

[0032] The adjustment assembly 12 includes two symmetrically arranged bases 121, a balance arm 122 rotatably arranged on the bases 121, a connecting block 123 hinged to one end of the balance arm 122 and fixedly connected to the suspension rope, a connecting block 2 124 hinged to the other end of the balance arm 122, and a connecting rope 125 fixedly connected between the two connecting blocks 2 124.

[0033] In actual use, the lifting device and the cathode plate are connected. When the winding mechanism 101 lifts the cathode plate by winding the lifting rope, when the force on one side of the balance arm 122 is large, since the length of the lifting rope is fixed, but the lifting rope can be slightly stretched, it will rotate slightly towards the side of the connecting block 123. This will pull the other balance arm 122 towards the side of the connecting block 224 through the connecting rope 125, so that the two balance arms 122 swing in a cycle. That is, the balance of the lifting device is adjusted by the multiple slight rotations of the balance arms 122, so that the lifting device can be quickly adjusted to a balanced state when it shakes.

[0034] As a further explanation of this application:

[0035] The connecting rope 125 is equipped with an adjustment component 2 13 for adjusting the distance between the two connecting blocks 2 124. During assembly, the distance between the two connecting blocks 2 124 is adjusted by adjusting component 2 13, thereby adjusting the level of the lifting device.

[0036] As a further explanation of this application:

[0037] The connecting rope 125 is disconnected from the middle position. The adjustment component 2 13 includes two connecting ends 131 fixedly connected to the disconnected position of the connecting rope 125, a screw 132 rotatably disposed on the connecting ends 131, and a connecting rod 133 threadedly connected between the two screws 132.

[0038] When adjusting the distance between the two connecting blocks 124 by adjusting component 2 13, the screw 132 is rotated inside the connecting rod 133 by rotating the screw 132, that is, adjusting the length of the screw 132 inside the connecting rod 133, thereby achieving the purpose of adjusting the distance between the two connecting blocks 124.

[0039] As a further explanation of this application:

[0040] The winding mechanism 101 includes a drum 1011 rotatably mounted on the running trolley 1 and a geared motor 1012 mounted on the running trolley 1 to drive the drum 1011 to rotate. Both ends of the lifting rope are fixedly connected to the drum 1011. After the geared motor 1012 is started, it drives the drum 1011 to rotate, thereby realizing the winding of the lifting rope.

[0041] As a further explanation of this application:

[0042] The trolley 1 is equipped with a rope pressing assembly 14 for pressing the lifting rope onto the drum 1011. When the lifting device is fully lowered, the lifting rope is in a slack state. The rope pressing assembly 14 presses the lifting rope onto the drum 1011 to prevent the lifting rope on the drum 1011 from becoming tangled.

[0043] As a further explanation of this application:

[0044] The rope pressing assembly 14 includes a first connecting seat 141 fixedly connected to the running trolley 1, a second connecting seat 142 fixedly connected to the first connecting seat 141, and a rope pressing roller 143 rotatably disposed on the second connecting seat 142;

[0045] Connecting seat 141 and connecting seat 2 142 are respectively provided with perpendicular waist holes 144, and connecting seat 141 and connecting seat 2 142 are fixedly connected by bolts passing through the waist holes 144.

[0046] The relative positions of the second connecting seat 142 and the first connecting seat 141 can be adjusted through the two perpendicularly arranged waist holes 144, so that the pressure roller 143 can be adjusted to press against the drum 1011.
