Abstract

The utility model relates to an automatic loading and unloading hanging tool composed of a hanging cable, a hanging beam and two hanging lock mechanisms, wherein each hanging lock mechanism comprises a movable block 1, a right hook 2, a right lock plate 5, a left hook 6, a left lock plate 3, a cross beam 8 and a movable supporting device. The hooks can automatically enclasp lifted objects when the hanging tool rises to realize lifting work. After the lifted objects are placed in fixed positions, the hooks can automatically unclamp. The utility model is suitable for the lifting work of the lifted objects with rectangular sections and curved surfaces.

Description

Automatic loading and unloading sling

The utility model is a kind of automatic loading and unloading suspender, and it belongs to the elevator machinery field.

Existing lifting means be with steel rope through lifting thing bottom, the upper end is suspended on the suspension hook, suspension hook carries out lifting job when rising, put down the lifting thing after, steel rope is extracted out.This method labour intensity is big, efficient is low, poor stability.

The purpose of this utility model is at the problems referred to above, and a kind of lifting device that can realize freight handling automatization is provided.

The utility model is to realize like this (referring to accompanying drawing):

A kind of automatic loading and unloading suspender has a hoist cable that can connect the weight-lifting equipment suspension hook above it, its technical essential is by hoist cable, and hanging beam and two hang latch mechanism and constitute, and the two ends of hanging beam connect hoist cable respectively and hang latch mechanism.Hang latch mechanism and comprise loose piece 1, right suspension hook 2, right jam plate 5, left suspension hook 6, left jam plate 3, crossbeam 8, kinematic support device.Right suspension hook and right jam plate, left suspension hook and left jam plate all adopt captives joint mode, between two chutes on left and right jam plate and the loose piece 1 active pin shaft 4 is housed, left and right suspension hook is connected the two ends of crossbeam 8 through hinges 9, spring 7 is contained in the chuck of loose piece 1 two bottom sides, and the kinematic support device is installed in the both sides of crossbeam.

Below to the other technologies feature launch the explanation:

Horizontal lock pin 11 is equipped with at loose piece 1 middle part, and the lock pin afterbody is equipped with spring 10, and the contact 12 of lock pin front portion contacts with the open-work on the left and right jam plate 3,5 is movable.

The kinematic support device comprises control stalk 13, lengthening control stalk 15, stay bearing plate 17, pressing plate 20, pull bar 21, kinematic support 22.Stay bearing plate is fixed on the both sides of crossbeam 8, and stay bearing plate and pull bar are connected the kinematic support of pressing plate by hinges; Bearing pin 14 connects control stalk 13 and lengthening control stalk 15, and the lengthening control stalk is contained in the orienting sleeve 16; Pressing plate 20 front ends are equipped with pulley 18, and pulley contacts with the track of both sides, loose piece 1 bottom; The two ends of extension spring 19 connect stay bearing plate 17 and pull bar 21 respectively.

Two chute tracks on the loose piece 1 are linear, and the contact surface of left and right suspension hook 6,2 and lifting thing is a planar structure.

Two chutes on the loose piece 1 can also be curvilinears figure, and the contact surface of left and right suspension hook 6,2 and lifting thing is a curved-surface structure just.

The principle of work of brief description suspender:

Hanging the loose piece of locking 1 can move up and down along the relative crossbeam 8 of direction of orienting sleeve 16 controls.When moving on the loose piece 1, pin-and-hole on the left and right jam plate 3,5 outwards moves on two chute tracks of loose piece 1 under the constraint of active pin shaft 4, and 6,2 on left and right suspension hook is under the constraint of crossbeam 8 and hinges 9, inwardly rotation, inwardly the result of rotation embraces the lifting thing.Upwards carry active pin shaft 4 and be on the inclined-plane owing to work the loose piece 1 of slinging, so the lifting thing is had bigger gripping power, the lifting thing can not come off.

Meanwhile, pulley 18 is upper and lower moving on the inclined-plane of loose piece, under the drive of pressing plate 20, extension spring 19 elongated, and under the promotion of pull bar 21, this kinematic support 22 is in and vertically (stretches out) position, obviously the support distances maximum of this moment.When putting down the lifting thing, kinematic support 22 contacts with the lifting thing and by gravity keeps the upright position motionless, abdicate the space that moves down for lengthening control stalk 15, when suspender continues to fall, crossbeam 8 is no longer mobile, and loose piece 1 is under suspender deadweight effect, and the elastic force that overcomes spring 7 moves down, move in the chute track of pin-and-hole on the left and right jam plate 3,5 on the

loose piece

1,6,2 on left and right suspension hook moves outward a lifting thing is unclamped.

Because moving down to horizontal lock pin 11, control stalk 13 and lengthening control stalk 15 abdicate mobile space under himself action of gravity, when the lockhole of left and right sides jam plate arrives latched position, laterally lock pin 11 is under the promotion of spring 10, and contact 12 reaches in the lockhole, and is locked left and right sides suspension hook.Pulley is in vacant state 18 this moments, and pull bar 21 loses constraint.After suspender left the lifting thing, kinematic support 22 revolved to turn 90 degrees and is in level attitude under the pulling force of extension spring 19, i.e. kinematic support withdrawal.When carrying out lifting operation again, lengthening control stalk 15 will be opened left and right jam plate 3,5 under the promotion of lifting thing.It is to lock and unblank that kinematic support mainly acts on, and cooperates to hang the action that latch mechanism is realized automatic loading and unloading.

When characteristics of the present utility model as mentioned above are that suspender drops on the lifting thing, rely on the suspender deadweight can untie locking mechanism automatically, when moving on the suspender about suspension hook the lifting thing is tightly embraced the enforcement lifting job.Rely on during thing the suspender deadweight that left and right sides suspension hook is opened reaching to be automatically locked when being scheduled to aperture when putting down lifting.When rising, suspender throws off with the lifting thing.Its work is sensitive, efficient is high, safe and reliable.

The utility model embodiment:

Example 1: the linear suspender (referring to accompanying drawing 1) that is applicable to rectangle, plate shape, trapezoidal uniform cross section lifting thing.

Example 2: the curvilinear figure suspender (referring to accompanying drawing 2) that is applicable to round sections such as steel pipe, cement pipe, bar.
