Description

Flywheel clutch spreader

technical field

The invention relates to the field of slings, in particular to a flywheel clutch sling.

Background technique

During the engine assembly process, the flywheel and clutch need to be pre-assembled and balanced with the flywheel at the bottom and the clutch at the top before assembly, and then stacked and transported to the assembly line at the same time with the flywheel at the bottom and the clutch at the top. It is to install the flywheel first and then install the clutch. The clutch pressed on it must be removed from the flywheel before assembly. Since there is no suitable spreader, the flywheel and clutch have been directly grabbed and lifted by hand and assembled to the engine. The flywheel, The clutch is heavy, and it is very laborious to lift and install it by hand. The labor intensity is high, and it is not easy to grasp and control. Therefore, there is an urgent need to design and manufacture a safe, reliable and versatile spreader to reduce labor intensity and meet the needs of safe production, and to avoid frequent replacement of flywheel and clutch when lifting two different parts, so as to ensure lifting efficiency.

Detailed ways

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment. It should be understood that the "upper", "lower", "left", "right", "front" and "reverse" mentioned in the following embodiments of the present invention are all based on the directions shown in the figures, These words used to limit the direction are only for convenience of description, and do not mean to limit the specific technical solution of the present invention.

The structure of the flywheel clutch hanger of the present invention is simple and reasonable. The clutch is hoisted by directly hooking the hook head into the inner ring at the root of the clutch release claw. The V-shaped notch is hooked into the bolt shaft to lift the flywheel, which has high hoisting stability and efficiency, good versatility, and can reduce labor intensity.

The following detailed description illustrates the present disclosure by way of example and not limitation, and it should be understood that various aspects of the present disclosure can be implemented alone or in combination with other aspects. This specification clearly enables one skilled in the art to make and use what we believe to be new and non-obvious improvements, describes several embodiments, workarounds, variations, alternatives, and applications of systems, including The best mode of the principles of the invention described in the specification. The use of "a", "an", "the" and "said" when describing elements or features and/or embodiments is intended to mean having one or more of the elements or features. The terms "comprising", "comprising" and "having" are intended to be inclusive and mean that there are additional elements or features other than those specifically described.

As shown in Figures 1 to 3, the specific structure of the flywheel clutch hanger includes: handrail 1 and ring weldment 2, transition joint 3 welded at the bottom end of ring weldment 2 and hook head 4 fixed at the bottom end of transition joint 3 , Handrail 1 is used to manually adjust the spreader during the lifting process, so that it can smoothly hook into the inner ring at the root of the clutch release claw to lift the clutch, or hook into the bolt rod to lift the flywheel. The transition joint 3 is used to fix the hook head 4 to the bottom end of the suspension ring weldment 2, and the hook head 4 is used to hook into the inner ring at the root of the clutch release claw to lift the clutch, or hook into the bolt shank to lift the flywheel. The flywheel clutch spreader has high hoisting stability and efficiency, good versatility, and can reduce labor intensity, so as to avoid manual lifting and installation, which is very laborious, labor intensive, difficult to grasp, and difficult to handle. , There are potential safety hazards such as flywheels, clutches falling to the ground, and brutal operations that may damage parts and injure people.

As shown in Figure 4, the lifting ring weldment 2 is a vertically arranged rod with a circular cross section, a circular lifting ring 21 is bent on the top end, a small-diameter thread head 22 extends downward on the bottom end surface, and the handrail 1 is an inverted L-shaped rod. shape, the outer end of the upper small rod is welded on the side of the suspension ring 21, and the lower large rod is parallel to the axial direction of the suspension ring weldment 2 and arranged vertically.

As shown in Figure 5, the transition joint 3 is in the shape of a pipe sleeve, with an axially through internal threaded hole 31, and the bottom end has a hook head clamping step 32. Screw into the internally threaded hole 31 of the transition joint 3, connect the two together and fix them by welding.

As shown in Figure 6, one end of the hook head 4 has a concentric axis, a through hole 41 and a counterbore 42 arranged up and down. Go through the counterbore 42 and the through hole 41, and then screw into the internally threaded hole 31 of the transition joint 3 so that the hook head 4 is locked and fixed to the bottom end of the transition joint 3. The port peripheral side of the through hole 41 has a transition joint engagement step 44 that fits and engages with the hook engagement step 32 at the bottom end of the transition joint 3 . The other end of the hook head 4 has a V-shaped notch hook head 45 that is bent upward, and the inside of the V-shaped notch hook head 45 has clutches that are indented on both sides. Each separating pawl transitional hook into part 46 is used for hoisting clutch, and the V-shaped notch of V-shaped notch hook head 45 is used for hooking into the bolt shank portion that is screwed into in advance on the plane that flywheel is installed clutch, to hoist flywheel.

Before hoisting, first hook the crane hook into the lifting ring 21 of the spreader. When hoisting the clutch, grasp the handrail 1 with your hands, and hook the hook head 4 directly into the inner ring at the root of the clutch release claw to lift. At the same time, ensure that the hook head The transitional hooks 46 of the separation claws of the clutch at the root can smoothly hook into the gap between the separation claws of the clutch until the root; The V-shaped notch of the V-shaped notch gib head 45 on the top is hooked into the bolt shank and the flywheel can be lifted. After hoisting, the flywheel or clutch is naturally turned from a horizontal state to a vertical upward slightly forward state, which is consistent with the assembly state. After hoisting, if the workpiece needs to be placed from a vertical state to a horizontal state, it only needs to be lowered directly. There is no need to change the spreader during the whole process of hoisting the flywheel and the clutch, and the hook head is replaceable.

To sum up, the structure of the flywheel clutch hanger is simple and reasonable. The clutch is hoisted by directly hooking the hook head into the inner ring at the root of the clutch release claw, screwing in a bolt on the plane where the clutch is installed on the flywheel, and then attaching the hook head of the hanger to the clutch. The V-shaped notch hooks into the bolt shaft to lift the flywheel, which has high hoisting stability and efficiency, good versatility, and can reduce labor intensity.

The above disclosures are only a few specific embodiments of the present invention, however, the present invention is not limited thereto, and any changes conceivable by those skilled in the art shall fall within the protection scope of the present invention.
