Description
Technical Field
[0001] This utility model relates to the field of grab cradle technology, specifically a connection structure between the grab cradle frame and the sheave. Background Technology
[0002] The spacing between the connecting steel wires of the top wheel of the platform is 1.4 meters, and the spacing between the supporting steel wires is 1.74 meters. However, when extending to the grab bucket cradle frame below, the spacing between the supporting steel wires becomes 1 meter, and the connecting steel wires are only 0.6 meters. This results in the connecting steel wires and supporting steel wires being too close together during use, causing them to become tangled and difficult to separate. If the operator is negligent, the connecting steel wires and supporting steel wires on the top wheel may jump out of their grooves. After jumping out of their grooves, the steel wires are prone to deformation, shortening their lifespan. Furthermore, the frequent tangling of the connecting steel wires and supporting steel wires requires separation, delaying production, wasting time, and increasing maintenance costs. To address these issues, a connection structure for the grab bucket cradle frame and the top wheel is needed. Utility Model Content

[0018] The working process of this utility model is as follows: When using the connection structure between the grab bucket cradle frame and the sheave, depending on the usage, the adjusting screw 403 is manually rotated. When the adjusting screw 403 rotates, it drives two sets of connecting sliders 407 to move along opposite and contradictory directions on the side wall of the adjusting screw 403. When the connecting sliders 407 move, they drive two sets of moving connecting plates 402 to move in the inner cavity of the fixed connecting plate 401 through the connecting rod 408 and the connecting slider 409. This adjusts the distance between the supporting steel wire 3 and the connecting steel wire 2 on the two sets of moving connecting plates 402. After adjustment, the bolts on the shaft retainer 405 are rotated to fix the fixed turntable 404. This reduces the entanglement and skipping phenomenon of the connecting steel wire 2 and the supporting steel wire 3 when they are wound up. Based on the adjusted angle of the supporting steel wire 3, the rotating screw 504 is manually rotated. After the rotating screw 504 rotates, the fixed gear plate 502 and the rotating gear plate 503 are separated by the action of the telescopic spring 505. After rotating the connecting plate 507, the angle of the supporting steel wire 3 supported by the stabilizing sleeve 508 is adjusted. After adjustment, the rotating screw 504 is tightened to make the supporting steel wire 3 more stable when supported, and further prevent the connecting steel wire 2 and the supporting steel wire 3 from getting tangled.
