Description
Technical Field
The utility model belongs to the technical field of reclaimer rotary cable pulleys, and relates to a reclaimer rotary cable pulley moving range fixing device.
Background
The rated material taking capacity of the QL6000.55 bucket wheel reclaimer is 6000t/h, and the rotation range is 0+/-170 degrees, as shown in figure 1. The central hole cable of the reclaimer is a6 kilovolt rubber flexible cable and other control cables, the cable has stretching resistance and flexibility, the power and control cables are connected to an electric room at the upper part of the reclaimer through a suspended pulley, and a transit junction box is arranged below the central hole.
The reclaimer has to revolve left and right during operation, the central hole cable pulley moves on the cable pulley rail of circular I-steel (pulley rail) during revolution, and during operation near the dam foundation side, the reclaimer needs to revolve to nearly the extreme position, and the cable pulley will also move to the extreme position at this moment. Due to the clamping stagnation and unconstrained condition of the cable pulley, the cable is often extruded and stretched, and the reciprocating rotary motion causes the cable to be worn and broken, so that power failure and control network failure are brought to equipment.
The reclaimer rotary cable pulleys are generally provided with 6 pulleys A1 which are arranged on a rotary door seat frame below a rotary large bearing, and pulleys A2-A6 which are arranged outside a central chute and are slidably arranged on a cable pulley track. When the reclaimer rotates, the head car A2 drags the adjacent pulleys to move through the steel wire rope between the two pulleys.
When the reclaimer works at the left and right limit, pulleys A2-A6 on the cable pulley track are also positioned at the limit position, and the pulleys are in a stacking or uniformly distributed state at the moment:
1. when the reclaimer works at the right limit position, all pulleys A2-A6 on the cable pulley rail are positioned at the right limit position, and the pulleys are in a stacking state. As shown in the situation of fig. 2, when the large arm is in the right limit condition, the pulley A1 is a fixed pulley and does not act along with the large rotary structure; the pulley A2 is a traction pulley arranged on a cable pulley track and rotates along with the large machine; the pulleys A3-A6 are middle movable pulleys, the traction pulley A2 drives A3, A3 drives A4, and the pulleys sequentially move on the cable pulley track.
As can be seen from fig. 2 and 3, when the boom is at the right limit, all of the pulleys A2-A6 on the cable pulley track are in the front semicircle, the angle of A2 and A6 is 140 °, and the angle of the corresponding center of rotation of each pulley is 33 °, and the total 165 ° is required for the five pulleys on the circular i-steel to be extruded together. Because of the bending tension between the cables, it is not possible for the buffer slides of each trolley to squeeze against each other, so A6 will be pulled further, because A1 is stationary, so the cable between A1 and A6 will be pulled and squeezed against other steel structures.
2. When the reclaimer works at the left limit position, all the pulleys A2-A6 on the cable pulley rail are positioned at the left limit position, and the pulleys A2-A6 are in an even distribution state. When the boom is in the left extreme position, as shown in fig. 4 and 5, A2 is rotated 340 ° to the left with the boom from the position in fig. 2 to the left extreme position, at which time the four movable pulleys A3 to A6 are moved on the cable pulley track by the traction pulley A2 via the wire rope. At this time, the A6 connected with the lower fixed pulley A1 moves from the right side to the left side, and the cable between the A1 and the A6 is pulled due to the large movement of the A6.
When the two conditions are the left and right rotation limit positions, as A6 cannot be guaranteed to move in a determined range on the cable pulley rail, cable stretching can occur between A1 and A6 at the left and right limit positions, and meanwhile, cable pulling and steel structure extrusion or pulley extrusion cause serious damage to the cable; and because the cable that reserves between A1 and A6 is longer for the cable is in the rotation process about, and the cable produces the friction with the coaster that swift current section of thick bamboo steel structure or door seat frame are fixed, causes the wearing and tearing of cable in the past, brings the injury to equipment and personnel.
