Abstract

A quick hook and suspension shaft special for an underslung conveyor comprises a hook and a wheel which is mounted at the bottom of the hook through a pin shaft. The quick hook and suspension shaft is characterized in that the hook is an l-shaped hook provided with an opening, the suspension shaft slides in the hook through the opening of the same, a U-shaped side lug and a C-shaped side lug are respectively arranged on two sides of the hook, an internal surface of the U-shaped side lug is larger than that of the hook, the C-shaped side lug is a major arc more than 180 degrees and is coaxially arranged with a circular arc section at the bottom of the hook, and the inner diameter of the C-shaped side lug is larger than the effective width of the hook. Since the hook is designed to be l-shaped, vertically passing in and out of the suspension shaft can be realized; meanwhile, a disc matched with the C-shaped side lug of the hook is arranged on the suspension shaft, and the disc and the C-shaped side lug can be automatically locked after the suspension shaft rotates by a certain angle; in the structure, a stressed part is formed by matching of the suspension shaft and the hook, and a locked part is formed by matching of the disc and the C-shaped side lug.

Description

The special-purpose quick hook of a kind of overhead chain conveyer and suspended axle

Technical field

The hook part often being used in a large number in suspension, especially this suspension of using in the occasion that the present invention relates in auto production line need auto parts and components especially panel beating housing etc. to be handled upside down.

Background technology

Overhead chain conveyor in auto production line, especially sheet metal component needs the overhead chain conveyor using in the production of electrophoresis, spraying, basic structure comprises ground rail, hook, suspended rail and hanger, hanger is wherein suspended on suspended rail, and move under the drive of power chain, hook is wherein positioned at the bottom of hanger, and is provided with wheel in the bottom of hook, and wheel is overlapped on ground rail and coordinates with ground rail.Owing to there being horizontal surface also to have inclined-plane in motion process, as described in CN100411927C as open in Chinese patent, so require it to there is the function that completes fast suspension, to meet the function while moving on inclined-plane with locking simultaneously, the insufficient strength of current hook, and wearing and tearing are also more serious.

Summary of the invention

The object of the present invention is to provide a kind of quick hook and overhead chain conveyor, can meet the function of quick suspension and inclination auto lock, meanwhile, the area of contact between hook and objective table is larger, longer service life.

The present invention solves the technical scheme that its technical matters takes: a kind of quick hook, comprise hook and wheel, described wheel is arranged on the bottom of hook by bearing pin, it is characterized in that, described hook is " 1 " font hook with an opening, in the both sides of described hook, being respectively equipped with U-shaped picking up the ears picks up the ears with C type, the described U-shaped inside face size of picking up the ears is greater than hook inside face size, described C type pick up the ears for be greater than 180 degree major arc and with concentric setting of circular arc portion of hook bottom, the internal diameter that described C type is picked up the ears is greater than the Effective width of hook.

Outside the described U-shaped inside face of picking up the ears is more equidistant than hook inside face, move 1 millimeter.

Described U-shaped picking up the ears picked up the ears respectively by being welded to connect the both sides that are fixed on hook with C type.

The suspended axle that a kind of and above-mentioned quick hook is used in conjunction with, it is characterized in that, on described suspended axle, fix a disk, and the Effective width that the diameter of described disk is greater than described quick hook opening is less than effective internal diameter that C type is picked up the ears, in described disk both sides, be provided with two milling planes with described quick hook openings of sizes corresponding matching.

Described disk and suspended axle are for being welded to connect.

The invention has the beneficial effects as follows: the present invention is designed to 1 font by hook, realize the vertical turnover of suspended axle, on suspended axle, be provided with disk simultaneously, disk picks up the ears to coordinate with the C type of hook, can realize both auto locks, after suspended axle rotates to an angle in this kind of structure, part of the force is the cooperation of suspended axle and hook, lock portion is, disk and coordinating that C type is picked up the ears, and two functional parts separate.

Fig. 7 is for being used constitution diagram.

In figure: 1 hook, 11 openings, 12 U-shaped picking up the ears, 13 C types are picked up the ears, 2 wheels, 21 bearing pins, 3 suspended axles, 31 disks, 32 planes, 4 transition rod members, 41 upper ends, 42 middle parts, 43 bottoms.

The specific embodiment

As shown in Figures 1 to 7,

, comprising hook 1 and wheel 2, wheel 2 is arranged on the bottom of hook by bearing pin 21, and wheel coordinates with the ground rail of overhead chain conveyor downside.Wheel is wherein the slotted V shaped wheel of middle tool, can coordinate with the track on ground.

Hook 1 is for having " 1 " font hook of an opening, particularly, links up with widely up and down, and opening 11 is positioned at oblique upper, and suspended axle 3 slips into from upper end, completes quick suspension.Linking up with 1 top is fixed on transition rod member 4, being formed by three sections of upper, middle and lowers of this transition rod member, there is the radian of a C shape upper end 41, for arc, middle part 42 is montant, and on montant, is provided with a flat board, for coordinating with guiding mechanism, bottom 43 is fixed end, is provided with and links up with the bolt hole being connected.

Hook 1 both sides weld respectively one U-shaped pick up the ears 12 and C type pick up the ears 13, U-shapedly pick up the ears 12 more biggerly than hook, make U-shaped 12 inner surface diameter of picking up the ears than large 1 millimeter of hook inner surface diameter.C type pick up the ears 13 for be greater than 180 degree major arc and with concentric setting of circular arc portion of hook bottom, pick up the ears 13 internal diameter of C type is greater than the Effective width of hook, makes like this disk 31 parts of suspended axle 3 can enter into smoothly C type and picks up the ears 13.Described U-shaped pick up the ears 12 and C type pick up the ears 13 respectively by being welded to connect the both sides that are fixed on hook, construct very simple.

A kind of suspension type objective table, on objective table for fixing pending auto parts and components, the both sides of objective table are respectively equipped with suspended axle 3, suspended axle extends outward, for circular shaft, can coordinate with quick hook, a welding disk 31 in side on suspended axle, and two opposite flanks of disk 31 are the plane 32 that can slide in hook, this plane 32 forms by milling on disk, and the diameter of disk is greater than the Effective width of hook opening and is less than effective internal diameter that C type is picked up the ears, make disk 31 and the C type 13 formation free-running fits of picking up the ears, the engaging of formation actv., for locking mechanism.

Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.
