Description

Technical Field

[0001] The invention relates to the technical field of cathode plate lifting, and in particular to a running trolley for a cathode plate lifting crane. Background Art

[0002] In the electrolytic metal and non-ferrous metal smelting industries, cathode plates are important production components, and their hoisting is an indispensable part of the production process. However, in the process of existing cranes hoisting cathode plates, due to the large number, heavy weight and irregular shapes of cathode plates, it is difficult to ensure their uniform distribution on the hoist when lifting multiple cathode plates at the same time. This uneven distribution directly leads to the fact that at the moment of lifting, the resultant force point of the gravity line of each cathode plate deviates from the geometric center of the hoist, causing the hoist to shake.

[0003] The shaking of the hoisting equipment not only increases the difficulty and risk of the hoisting operation, but may also cause damage to the cathode plate itself, such as edge wear, deformation or even breakage. In addition, the shaking may also affect the stability and safety of the crane, and in serious cases may even cause safety accidents;

[0004] The shaking of the spreader mainly occurs when the spreader is lifting and when the moving direction of the trolley is deviated; when the trolley moves deviated in a state of linear motion, causing a change in direction, the movement state of the spreader will change, causing the spreader to shake.

[0005] Therefore, a cathode plate crane operating trolley is needed to overcome the above-mentioned problems. Summary of the invention

[0006] In order to solve the above problems, an embodiment of the present invention provides a running trolley for a cathode plate crane, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: a running trolley for a cathode plate crane, comprising a running trolley, a lifting assembly for lifting a sling is arranged on the running trolley, and an adjusting assembly 1 is arranged on the lifting assembly;

[0008] The first adjustment component includes two symmetrically arranged bases, a balancing arm rotatably arranged on the base, a connecting block 1 hingedly arranged at one end of the balancing arm and fixedly connected to the suspension rope, a connecting block 2 hingedly arranged at the other end of the balancing arm, and a connecting rope fixedly connected between the two connecting blocks 2;

[0009] The running trolley is provided with a horizontal wheel set for preventing the running trolley from deflecting when traveling;

[0010] The horizontal wheel group includes a mounting frame fixedly connected to the running trolley, an eccentric shaft rotatably arranged inside the mounting frame, a gear fixedly connected to the eccentric shaft, a limiting tooth fixedly connected to the mounting frame for limiting the gear, and a guide pulley rotatably arranged at an eccentric position of the eccentric shaft.

[0011] As a further improvement of the above technical solution:

[0012] The lifting assembly comprises a winding mechanism arranged on the running trolley, a fixed pulley block arranged on the running trolley, and a lifting rope arranged on the winding mechanism and connected to the fixed pulley block.

[0013] The reeling mechanism comprises a reel rotatably arranged on a running trolley, and a reduction motor installed on the running trolley for driving the reel to rotate. Both ends of the suspension rope are fixedly connected to the reel.

[0014] The running trolley is provided with a rope pressing assembly for pressing the suspension rope onto the drum.

[0015] The rope pressing assembly comprises 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 arranged on the connecting seat 2;

[0016] The connecting seat 1 and the connecting seat 2 are respectively provided with perpendicular waist holes, and the connecting seat 1 and the connecting seat 2 are fixedly connected by bolts penetrating the waist holes.

[0017] The connecting rope is provided with an adjusting component 2 for adjusting the distance between the two connecting blocks 2.

[0018] The connecting rope is disconnected from the middle position, and the second adjusting component includes two connecting ends fixedly connected to the disconnected position of the connecting rope, a screw rod rotatably arranged on the connecting end, and a connecting rod threadedly connected between the two screw rods.

[0019] The beneficial effects of the embodiments of the present invention are:

[0020] In actual use, the sling is connected to the cathode plate, and the reeling mechanism lifts the cathode plate by reeling in the sling rope. When the balancing arm on one side is subjected to a large force, the sling rope has a certain length, but the sling rope can be slightly stretched, so that it rotates slightly toward the side of the connecting block one, thereby pulling the other balancing arm to rotate slightly toward the side of the connecting block two through the connecting rope, so that the two balancing arms swing in a cycle, that is, the balance of the sling is adjusted by multiple slight rotations of the balancing arm, so that the sling can be quickly adjusted to a balanced state when it shakes;

[0021] In actual use, two guide pulleys are arranged inside the groove of the walking beam, and the movement of the running trolley is limited by the two guide pulleys to prevent the running trolley from deflecting during movement;

[0022] An adjusting component 2 for adjusting the distance between the two connecting blocks 2 is provided on the connecting rope. During assembly, the distance between the two connecting blocks 2 is adjusted by adjusting the component 2, thereby adjusting the level of the sling. When adjusting the distance between the two connecting blocks 2 by adjusting the component 2, the screw is rotated inside the connecting rod by rotating the screw rod, that is, the length of the screw rod retracted into the connecting rod is adjusted, thereby achieving the purpose of adjusting the distance between the two connecting blocks 2.

[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0039] See also Figures 1 to 8 The embodiment of the present invention discloses a running trolley for a cathode plate crane, comprising a running trolley 1, a lifting assembly 10 for lifting a sling is arranged on the running trolley 1, and an adjusting assembly 12 is arranged on the lifting assembly 10;

[0040] The adjustment component 12 includes two symmetrically arranged bases 121, a balancing arm 122 rotatably arranged on the base 121, a connecting block 123 hingedly arranged at one end of the balancing arm 122 and fixedly connected to the suspension rope, a connecting block 124 hingedly arranged at the other end of the balancing arm 122, and a connecting rope 125 fixedly connected between the two connecting blocks 124;

[0041] In actual use, the sling is connected to the cathode plate, and the reeling mechanism 101 lifts the cathode plate by reeling in the sling rope. When the balancing arm 122 on one side is subjected to a large force, the sling rope has a certain length, but the sling rope can be slightly stretched, so that it is slightly rotated toward the side of the connecting block 123, thereby pulling the other balancing arm 122 to slightly rotate toward the side of the connecting block 2 124 through the connecting rope 125, so that the two balancing arms 122 swing in a cycle, that is, the balance of the sling is adjusted by multiple slight rotations of the balancing arm 122, so that the sling can be quickly adjusted to a balanced state when it shakes;

[0042] The running trolley 1 is provided with a horizontal wheel set 17 for preventing the running trolley 1 from deflecting when traveling;

[0043] The horizontal wheel set 17 includes a mounting frame 171 fixedly connected to the running trolley 1, an eccentric shaft 172 rotatably arranged inside the mounting frame 171, a gear 173 fixedly connected to the eccentric shaft 172, a limiting tooth 174 fixedly connected to the mounting frame 171 for limiting the gear 173, and a guide pulley 175 rotatably arranged at an eccentric position of the eccentric shaft 172; two eccentric shafts 172 are symmetrically arranged on the mounting frame 171;

[0044] In actual use, two guide pulleys 175 are arranged inside the groove of the walking beam, and the movement of the running trolley 1 is limited by the two guide pulleys 175 to prevent the running trolley 1 from deflecting during movement;

[0045] In actual use, the center distance between the two guide pulleys 175 is changed by rotating the eccentric shaft 172, so that the two guide pulleys 175 can be adapted to walking beams of different sizes for use.

[0047] The lifting assembly 10 comprises a reeling mechanism 101 arranged on the running trolley 1 and a fixed pulley block 102 arranged on the running trolley 1 ; the lifting rope is arranged on the reeling mechanism 101 and connected to the fixed pulley block 102 .

[0048] The winding mechanism 101 includes a drum 1011 rotatably arranged on the running trolley 1, and a reduction motor 1012 installed on the running trolley 1 for driving the drum 1011 to rotate. Both ends of the sling rope are fixedly connected to the drum 1011. After the reduction motor 1012 is started, it drives the drum 1011 to rotate, thereby realizing the winding of the sling rope.

[0049] As a further illustration of this application:

[0050] The running trolley 1 is provided with a rope pressing assembly 14 for pressing the lifting rope onto the drum 1011; when the sling is fully lowered, the lifting rope is in a relaxed state, and the rope pressing assembly 14 is used to press the lifting rope onto the drum 1011, thereby preventing the lifting rope on the drum 1011 from becoming tangled.

[0051] As a further illustration of this application:

[0052] The rope pressing assembly 14 includes a connecting seat 141 fixedly connected to the running trolley 1, a connecting seat 142 fixedly connected to the connecting seat 141, and a rope pressing roller 143 rotatably arranged on the connecting seat 142;

[0053] The first connection seat 141 and the second connection seat 142 are respectively provided with vertical waist holes 144, and the first connection seat 141 and the second connection seat 142 are fixedly connected by bolts penetrating the waist holes 144;

[0054] Through two waist holes 144 arranged perpendicularly to each other, the relative positions of the second connecting seat 142 and the first connecting seat 141 can be adjusted, so that the rope pressing roller 143 can be adjusted to be pressed onto the winding drum 1011.

[0055] As a further illustration of this application:

[0056] The connecting rope 125 is provided with an adjusting component 13 for adjusting the distance between the two connecting blocks 124. During assembly, the distance between the two connecting blocks 124 is adjusted by adjusting the adjusting component 13, thereby adjusting the level of the sling.
