Description

Technical Field

[0001] The invention relates to the technical field of cable pay-off, and in particular to a pay-off frame for mining machinery and equipment. Background Art

[0002] In the prior art, there is a cable pay-off rack with a publication number of CN220906756U, which should have the characteristics of simple assembly and convenient transportation. The technical solution is a cable pay-off rack, comprising two parallel bases and two connecting rods vertically fixed between the bases; the characteristics are: the inner baffle of the base is provided with two support plates, and the support plates are provided with two insertion holes for inserting the connecting rods, and when the two bases are brought close together, the connecting rods simultaneously pass through the insertion holes of all the support plates to connect the two bases into one.

[0003] Although the above scheme has the above advantages, the disadvantage of the above scheme is that because the wire wheel is transported by rolling during transportation, this rolling method may cause damage to the edge of the wire wheel, resulting in pits or bulges due to contamination by other impurities. Both pits and bulges will cause the wire wheel to get stuck easily when rolling on the pay-off rack wheel to release the material, which makes it more difficult to pull the cable, and the above wheels cannot be adjusted for spacing during use. A wider spacing will increase the pulling and rolling force of the wire wheel, and a narrow spacing will make it easier to pull the line, but a narrow spacing will cause the lighter wire wheel to detach from the wheel during strong pulling, resulting in pulling instability.

[0048] The spacing adjustment mechanism 3 drives the type wheel 316 to move according to the weight data of the wire wheel 6, and adjusts the spacing between the two type wheels 316 during the rotating discharge process, so that the weight of the wire wheel 6 matches the support spacing, thereby ensuring the stability of the rotation of the wire wheel 6 and making the pulling of the wire wheel 6 more labor-saving.

[0052] A controller is fixed on one side of the base 11 , and the controller is electrically connected to the motor 42 , the push rod motor 211 , the pressure sensor 1 , the pressure sensor 2 and the oil pump 57 , respectively.

[0053] Working principle:

[0054] The installation program is started by the controller. The controller controls the motor 42 to drive the gear 43 to rotate forward. The forward rotation of the gear 43 satisfies the one-way gear 1 23 to drive the double-stage reciprocating threaded rod 1 22 to rotate. The rotation of the double-stage reciprocating threaded rod 1 22 causes the two sliders 1 26 to drive the screw box 28 away from each other. The screw box 28 moves and drives the slider 2 27 to slide on the guide rod 25. When the screw box 28 moves away, it drives the internal and upper structures to move. When the internal double-stage reciprocating threaded rod 2 31 moves, it pulls the belt 1 33 and the belt 2 35 to squeeze the shaft 1 39 for installation. The block 38 contracts the telescopic rod 36 below and compresses the spring 37, so that the slider 26 moves to the wire tail of the double-section reciprocating threaded rod 22 and then stops moving. At this time, the distance between the two screw boxes 28 is the largest, and then the wire wheel 6 is pushed into the groove of the push plate 212 through the ramp block 12 and the ramp block 213, and then the push rod motor 211 is started to push the push plate 212 upward to move the wire wheel 6 upward, and then the motor 42 is started to make the gear 43 rotate forward, so that the two screw boxes 28 approach each other. During the approach, the vertical plate 29 and the push rod 210 correct the wire wheel 6, so that the wire wheel 6 Located in the middle position, when the sensor pressure inside the two push rods 210 reaches the standard, it means that the correction of the wire wheel 6 is completed, and the screw box 28 is also reset. When approaching, the spring 37 pushes the telescopic rod 1 36 to move the mounting block 38 and the rotating shaft 1 39 and other structures upward and reset, so that the bevel gear 2 314 and the bevel gear 1 310 are re-engaged. After resetting, the circular plates at both ends of the wire wheel 6 are located inside the mounting ring 51 and between the multiple clamping plates 56. Then the oil pump 57 is controlled to fill the hydraulic oil into the hydraulic cylinder 55, so that the hydraulic cylinder 55 pushes the clamping plate 56 to approach the wire wheel 6. The edge of the circular plate, multiple clamping plates 56 correct the wire wheel 6 when it is close to the wire wheel 6, so that the central axis of the wire wheel 6 is in the same straight line with the central axis of the mounting ring 51, and then the push rod motor 211 is controlled to drive the push plate 212 to move down without contacting the wire wheel 6. At this time, the wire wheel 6 is installed. When disassembling, the push plate 212 is moved up, and the oil pump 57 pumps the oil in the hydraulic cylinder 55 away, so that the wire wheel 6 falls on the push plate 212, and then the motor 42 is started to drive the gear 43 to rotate forward, so that the screw box 28 drives the upper structure away, and the wire wheel 6 is manually removed to complete the disassembly;

[0055] The wire on the wire wheel 6 is manually pulled, and the wire pulls the wire wheel 6 to rotate. The wire wheel 6 rotates on the work wheel 316 through the clamping plate 56, the hydraulic cylinder 55 and the mounting ring 51. The mounting ring 51 is installed on the outside of the circular plate of the wire wheel 6 to prevent the depression or protrusion on the outside of the circular plate from affecting the smoothness of the line pulling and releasing, and to prevent the depression on the outside of the circular plate from being stuck on the outside of the work wheel 316, thereby reducing the friction between the wire wheel 6 and the work wheel 316, improving the smoothness of the release, and making the pulling more labor-saving;

[0056] The starting motor 42 drives the gear 43 to reverse, and the reverse rotation of the gear 43 makes the one-way gear 2 313 meet the direction of driving the rotating shaft 2 312 and the bevel gear 2 314 to rotate, and the bevel gear 2 314 drives the bevel gear 1 310 to rotate, and the bevel gear 1 310 drives the two double-section reciprocating threaded rods 2 31 to rotate through the rotating shaft 1 39, the pulley 1 32, the belt 1 33, the pulley 2 34 and the belt 2 35, so that the two U-shaped moving blocks 315 drive the industrial wheel 316 to move outside the double-section reciprocating threaded rod 2 31, and adjust the distance between the two industrial wheels 316, so as to match the appropriate spacing according to the weight of the wire wheel 6. For example, when the weight of the wire wheel 6 is heavier, a larger spacing will cause pulling to be more laborious, so the two industrial wheels 316 are brought closer to reduce the spacing, but because of the heavier weight, the wire wheel 6 will not be unstable The situation is fixed, so adjusting the spacing smaller can keep the wire wheel 6 stable and make pulling more labor-saving. After the wire wheel 6 becomes lighter, the smaller spacing will make the rotation of the wire wheel 6 unstable during pulling, and it is easy to separate from the industrial wheel 316 due to pulling. Therefore, when it gradually becomes lighter, the spacing between the two industrial wheels 316 is continuously increased according to the detection data of the second pressure sensor, so that the wire wheel 6 in the pulling process becomes more stable, and it is easier to pull as the wire wheel 6 becomes lighter. Therefore, increasing the spacing will not increase the pulling force of the wire wheel 6. When adjusting the spacing, the mounting ring 51 will make the arc plate 53 move up and down, and the arc plate 53 moves up and down to make the telescopic rod 2 54 telescope up and down. The arc plate 53 can increase the stability of the mounting ring 51, and prevent the mounting ring 51 from following the wire wheel 6 and separating from the industrial wheel 316 after the wire wheel 6 becomes lighter.
