CN2106815U - D-shape gripping hook - Google Patents

Abstract

The utility model relates to a D-shaped gripping hook used on conveyor belts, which comprises a top angle, two sides, a long hook and a short hook. The D-shaped gripping hook used on conveyor belts is characterized in that the cross section of the D-shaped gripping hook used on conveyor belts is different from the prior art and adopts a D-shaped cross section, and the exiting gripping hooks all have a circular cross section or the cross section of a flat surface, which has the defects of rugosity, affected quality of transmitting products, abrasions of equipment, bad abrasive resistance and short service life caused by being pressed and mounted on the plane of a wire mesh conveyor belt. The utility model overcomes the defects. No protrusion appears after press mounting, therefore, the product quality can be ensured, and the accuracy of equipment can be maintained.

Description

D-shape gripping hook

The utility model discloses the grab that uses on a kind of belt conveyor, it is that polyester guipure etc. is linked to be the grab that endless belt conveyer is used.

Past and be used for now the polyester webs belt lacing grab of papermaking and sewage disposal both at home and abroad all is with two kinds in round section or flat cross section.It is found that in production practice these two kinds of grabs cut both ways.The round section grab is fitted in when online, and it is bigger that a grab circle silk arc convex exceeds the guipure plane, forms a horizontally-arranged circular arc on the guipure surface of joint, when being used for paper industry transmission paper, round vestige is just printed off in l Water Paper one contact on paper, influences the plane quality of paper; Be used for sewage disposal when online, to be higher than the plane bigger because of the circle silk, influences reverse scraper plate operation.Both at home and abroad adopt now adhesive to fill the rough and uneven in surface place that the grab silk forms, and add drop cloth and remedy above-mentioned defective.But with this way adhesive is required very highly, it must heat resistance 150 ℃, good toughness, and the intensity height at room temperature solidifies fast, and strong with the affinity of stainless steel wire and polyester twine, and aging-resistant service life is more than 8000 hours.Such adhesive cost height uses it that every meter guipure tieing flat cost is reached about 10 yuan.Undesirable because of above-mentioned way, people use the flat filament grab instead and reduce grab and press-fit the height of processus aboralis for the guipure plane, but facts have proved, because the flat filament grab, the cross section is flat, wide, and it can not be pressed in the V-shaped groove seam of guipure warp formation, can only be pressed on net on bank, thereby make the height that is projected on the guipure plane little unlike the circular section grab, and consolidation not, simultaneously, the flat filament grab wear the pin place, be flat and thin circular arc, do not have the circular section diameter big, thereby wear ability is poor, and the life-span is low.

The purpose of this utility model provides the advantage of a kind of comprehensive circular section and flat cross section grab, does not give and transmits the D shape grab that thing is pressed into impression.

The technical solution of the utility model is introduced with following embodiment.

Fig. 1 is a kind of example structure scheme drawing of the utility model.

Fig. 2 is the birds-eye view of Fig. 1.

Present embodiment is to be wrapped on the mold with circle silk, forms through machinework and cutting, be shaped as subtriangular, identical with prior art, promptly include the drift angle of circular arc, dual-side and long hook, lack hook.Main points are cross sections, its drift angle A place for circular, and dual-side B and C and long hook E, lack hook F and partly all be processed into the D tee section, and the outside is the plane, and the inboard is a disc.Circle silk becomes D shape from the drift angle of grab gradually to the stage of 90 ° of beginnings to 150 of both sides angle of spread α °, the thickness of D tee section part is the 3/4-7/8 of circle filament diameter.

Through facts have proved, the great advantage of D shape grab is to reduce projecting height on guipure, keeps level and smooth, does not therefore hinder paper, the dryer surface precision of protection paper machine.Though manufacturing cost slightly increases, saved the expense of coating viscosity glue agent and drop cloth in use, final still suitable economically.

Another embodiment of the utility model is full D tee section, promptly need use special D tee section steel wire rolling or that gone out by the wire drawing of D shape mould.The outside of grab each several part is the plane, and the inboard is a disc.

Claims (4)

1, a kind of D shape grab, it is made subtriangular by the circular section steel wire, comprise drift angle, dual-side and long hook and short hook, it is characterized in that: the cross-sectional plane at drift angle circular arc place is for circular, and the dual-side and the hook portion outside become the plane, and the inboard is a disc, and cross-sectional plane is a D shape.

2, grab according to claim 1 is characterized in that: its D tee section is to be formed gradually by the stage that drift angle launches 90 ° of beginnings to 150 ° to both sides.

3, grab according to claim 1 is characterized in that: the thickness of said D tee section part is the 3/4-7/8 of circle filament diameter.

4, a kind of D shape grab, it comprises drift angle, dual-side, long hook and short hook, it is characterized in that: each outside of grab is the plane, and the inboard is a disc, and the cross-sectional plane of grab each several part all becomes D shape.
