The utility model discloses a kind of direct-connected shackle hook components, mainly solving the technical problems that increasing cable artificially in the prior art to control the positive and negative rotation of suspension hook, to be easy the problem of damaging to cable, the utility model passes through a kind of direct-connected shackle hook component, platform sling including two sides, it is successively arranged driving assembly from top to bottom between the platform sling of two sides, electromagnetic clutch, suspension hook axis, suspension hook, the suspension hook axis is equipped at least one angle limit ruler, the platform sling of side corresponding with the angle limit ruler is equipped with the technical solution of mechanical limit switch, preferably solves the problems, such as this, it can be used for controlling suspension hook rotation.

Description

A kind of direct-connected shackle hook component

Technical field

The utility model relates to a kind of direct-connected shackle hook components.

Background technique

Instantly traditional rotary hook group device mainly by motor, retarder, brake (" three-in-one " driving device), The composition such as pinion gear, gear wheel, suspension hook group.Gear wheel is driven by " three-in-one " driving device driving pinion, is nibbled by gear It closes transmission and drives the rotation of suspension hook group.When needing driving to power to the suspender under suspension hook, the length people for increasing cable can only be passed through For go control suspension hook positive and negative rotating function.Due to the inevitable cable bad of operation error, leaky is generated, is seriously threatened To the safety of operating personnel and equipment, to result in significant economic losses.

Utility model content

The technical problems to be solved in the utility model is the positive and negative rotation for increasing cable artificially in the prior art to control suspension hook, To be easy the problem of damaging to cable, a kind of new direct-connected shackle hook component is proposed, which, which has, is not necessarily to The characteristics of increasing positive and negative rotation of the cable to control suspension hook.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows: a kind of direct-connected shackle hook Component, the platform sling including two sides are successively arranged driving assembly between the platform sling of two sides from top to bottom, and electromagnetic clutch is hung Hook axis, suspension hook, the suspension hook axis is equipped at least one angle limit ruler, described in side corresponding with the angle limit ruler Platform sling is equipped with mechanical limit switch.

Further, it is preferable that the suspension hook axis passes through lifting beam with hook, and the platform sling of the lifting beam with hook and two sides is solid It is fixed.

It is highly preferred that the suspension hook axis being located above the lifting beam with hook is equipped with hook nut, the hook nut Bearing one is equipped between the lifting beam with hook.

It is highly preferred that being equipped with bearing two between the lifting beam with hook and the suspension hook axis.

Preferably, the driving component includes motor, the motor connection retarder, the retarder connecting brake, The platform sling of the brake connection electromagnetic clutch, the brake and two sides is fixed.

The utility model has the beneficial effects that: the utility model carries out rotation control to suspension hook by driving assembly；This Utility model realizes electric control on-off by electromagnetic clutch, does not need manual control；The utility model is opened by mechanical position limitation The cooperation with angle limit ruler is closed, realizes the positive and negative rotation control of suspension hook, simple process, accurate positioning；The utility model structure letter It is single, it is easy to operate, the rotational case of suspension hook can be preferably controlled, the service life of suspension hook is extended, avoids caused peace of leaking electricity Full accident.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.

Referring to Figure 1, present embodiment discloses a kind of direct-connected shackle hook component, the platform sling 1 including two sides, two sides Driving assembly, electromagnetic clutch 3, suspension hook axis 4, suspension hook 5, the driving component packet are successively arranged between the platform sling from top to bottom Motor 21 is included, the motor 21 connects retarder 22, and the reduction ratio between motor 21 and retarder 22 is 1249, has reduction ratio Greatly, small in size, run smoothly, output torque it is big, 22 connecting brake 23 of retarder, the brake 23 connects the electricity Magnet clutch 3, electromagnetic clutch 3 can be powered engagement, power-off separation, by motor 21 and a series of transmission to drive The rotation of suspension hook 5, the brake 23 and the platform sling 1 of two sides are fixed, and the suspension hook axis 4 passes through lifting beam with hook 6, described to hang Bearing 2 61 is equipped between hook crossbeam 6 and the suspension hook axis 4, the lifting beam with hook 6 and the platform sling 1 of two sides are fixed, are located at The suspension hook axis 4 of 6 top of the lifting beam with hook is equipped with hook nut 7, the hook nut 7 and the lifting beam with hook 6 it Between it is fixed by bolt 71, bearing 1 is equipped between the hook nut 7 and the lifting beam with hook 6, is set on the suspension hook axis 4 There is at least one angle limit ruler 41, angle limit ruler 41 has certain arc length, one or two angle limit ruler 41 is arranged Realize the positive and negative rotation in different ranges of suspension hook 5, the platform sling 1 of side corresponding with the angle limit ruler 41 is equipped with machine Tool limit switch 11；

When normal work, motor 21 is in energization rotating forward state, and electromagnetic clutch 3 obtains electric, suspension hook 5 such as arrow institute in Fig. 2 Show that direction rotates forward；When mechanical limit switch 11 touches angle limit ruler 41,3 power loss of electromagnetic clutch, motor 21 is in anti- Turn state, when electromagnetic clutch 3 again it is electric when, the direction as shown by the arrows in Figure 3 of suspension hook 5 reversion, so that it is positive and negative to reach suspension hook 5 The purpose turned.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
