[0022] 1. The bottom hanger is hingedly connected with the cable slide, which can slightly adjust the angle during hoisting according to the gravity of the component, such as inclined and non-horizontal hoisting of special-shaped components, so as to avoid stress concentration caused by rigid connection, reduce the overall shaking of the hoist, and improve the operation stability under non-standard working conditions.

[0023] 2. The shallow ring groove (normal speed) and deep ring groove (abnormal speed) of the center wheel are designed in steps, which can accurately guide the speed measuring column to trigger action (only when it enters the deep ring groove in abnormal situation), avoiding false braking.

[0024] 3. The speed measuring part rotates synchronously with the center wheel. When the center wheel suddenly accelerates due to load impact, the sliding block cylinder slides outward under the influence of increased centrifugal force, without the need for electronic sensors or manual intervention. The technical effect of pure mechanical structure realizes instantaneous triggering of action when the speed is abnormal, avoiding response lag caused by faults of electronic components in dusty and humid environments, and adapting to complex outdoor construction scenes.

[0025] 4. The initial tension of the tension spring can be flexibly adjusted by adjusting the lever. Pushing the adjusting plate with fingers makes the limiting teeth disengage from the limiting row of teeth. Dragging the adjusting lever can change the initial distance between the spring plate and the sliding block cylinder. When the initial tension is increased, higher centrifugal force (i.e. faster abnormal speed of the center wheel) is needed to trigger braking, which is suitable for heavy component hoisting. When the initial tension is decreased, slight speed abnormality can trigger braking, which is suitable for light components or precision hoisting, realizing the technical effect of one spreader being applicable to multiple working conditions.

[0026] 5. Multiple speed measuring parts rotate with the center wheel, successively pressing the down presser, driving the cable clamp plate to intermittently clamp the cable, which not only smoothly reduces the speed through friction, but also avoids violent shaking of the spreader or falling of the hoisted component, protecting the integrity of the cable and the hoisted object. After braking, manual resetting is not needed. When the load impact is removed and the center wheel returns to normal speed, the sliding block cylinder is reset under the action of the tension spring, the linkage and the clamping wedge are rebounded under the action of the reset spring, the cable clamp plate automatically releases the cable, and the spreader returns to normal operation, reducing manual intervention steps and improving construction efficiency.

[0027] 6. The inclined surface cooperation of the clamping wedge and the clamp slot part in the stabilizing assembly can automatically extrude the pressure plate when the cable clamp plate moves downward, so that the cable grooves on both sides uniformly wrap the cable, and the clamping force is stable.

[0053] In specific use, the bottom hanger 4 can be arranged on a sling, the cable passes through the guide rope hole 1121, the center wheel 12 and the guide wheel 13 roll on the cable, and the cable carrier 1 is driven by the traction rope to move reciprocatingly on both sides of the bridge. When the center wheel 12 rolls on the cable, the speed measuring part 2 rotates with the center wheel 12, is subjected to a centrifugal force, and the sliding block cylinder 22 and the speed measuring column 23 have a tendency to move outward. When the center wheel 12 runs stably, the sliding block cylinder 22 is pulled by the tension spring 242, and the centrifugal force is offset.

[0055] Meanwhile, the speed measuring part 2 can be adjusted according to the running speed of the sling. The fingers push the adjusting plate 243 upwards, so that the limiting teeth 2431 on the lower side of the adjusting plate 243 are disengaged from the limiting row of teeth 215. Then the adjusting rod 24 can be dragged to adjust the distance between the spring plate 241 and the sliding block cylinder 22 in the initial state, that is, to adjust the initial tension of the tension spring 242, and further to change the threshold value of the sliding block cylinder 22 and the speed measuring column 23 sliding outward.

[0056] It should be noted that in this document, the terms "comprise", "comprising", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or apparatus that comprises a list of elements does not only include those elements, but also includes other elements not expressly listed, or inherent to such a process, method, article, or apparatus.

[0057] Although embodiments of the present application have been shown and described, it will be understood by those having ordinary skill in the art that various changes, modifications, alternatives, and variations can be made thereto without departing from the principles and spirit of the application.

[0058] The above describes the present application and its embodiments, which are not limited, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto.
