Abstract

The utility model relates to a one-step forming trough type cable bridge, which consists of a trough bottom 1, a vertical side 2, a bending rib 3, reinforcing ribs 4 and a small side 5. The trough bottom 1 is an important component of the trough type cable bridge and plays a role of supporting a cable. The vertical side 2 is an important component forming a side edge of the cable bridge and plays a role of protecting the cable. The bending rib 3 is a hooked rib on an upper part of the vertical side, and not only plays a role of increasing the intensity, but also avoids scratching the hand and the cable. The reinforcing ribs 4 are two arc ribs on the upper part of the vertical side and play a role of increasing the intensity on the cable bridge. The small side 5 is a side with a shape of character 'yi' on the upper part of the vertical side and plays a role of increasing the intensity on the cable bridge. The one-step forming trough type cable bridge is formed by carrying out punching and ribbing on the bottom, carrying out punching on a trough edge and finally carrying out rolling, ribbing and bending. The production processes of unwinding, levelling, feeding, punching, ribbing, cutting, discharging, rolling and forming of a ladder type bridge are all realized by a novel and complete cable bridge production line. And under the condition of not influencing the strength, the material cost is saved and the labor intensity is reduced.

Description

Once-through slot type cable testing bridge

Technical field

The utility model relates to a kind of cable testing bridge, particularly a kind of once-through slot type cable testing bridge.

Background technique

In the sector product that on market, is occurred at present slot type crane span structure class all be with sheet material by cut, roll over, dash, operation such as gang welding is made.Each procedure is finished all must need check, it is low that the process of making product by this processes exists efficient, consumed great amount of manpower, material resources, especially also to carry out gang welding for the slot type crane span structure, not only the manufactured size precision of its product is low, and weldquality is difficult to guarantee, often exist and burn, welding slag is removed unclean, slag inclusion, weld defectss such as pore, also be easy to generate welding stress, giving down, one zinc-plated processing brings adverse effect, carry out stress relief so that product is caused big distortion by being heated, can only solve by adjustment now, but adjust the improper zinc damage layer that causes easily, affect for the outward appearance of product.And since heavier, also bigger for the labor intensity of installation personnel.

Summary of the invention

The utility model is to provide a kind of once-through slot type cable testing bridge that can overcome existing shortcoming at above problem; form by bottom land 1, stile 2, curved muscle 3, stiffening rib 4, little limit 5; the important component part of bottom land 1 slot type crane span structure; playing carrying cable stile 2 is important component parts of forming the side of cable testing bridge, has played the effect of protection cable.Curved muscle 3 is muscle that stile top is hook type, has both played the effect of gaining in strength, and the scuffing of having avoided staff and cable is arranged.Stiffening rib 4 is twice arched ribs on the stile, cable testing bridge has been played the effect of gaining in strength.Little limit 5 is limits that stile top is " one " font, cable testing bridge has been played the effect of gaining in strength.By bottom punching beading, the punching of terraced limit, last roll-in beading, bending and molding.The production process of slot type crane span structure from unreel, smoothing, feeding, punching, beading, cut-out, discharging, all be achieved to roll-forming by new, the complete cable testing bridge production line of a cover.The normally shear blanking of existing processing technology, punching, bending, gang welding (ladder class) moulding.It is not high that it has mainly overcome existing processing precision of products, improved the intensity of product, got rid of because weld defects and because caused other harmful effects of welding stress such as gang welding is causedly burnt, welding slag is removed clean, slag inclusion, pores.Under the situation that does not influence intensity, save cost of material simultaneously, reduced labor intensity.

Owing to adopted a lot of advanced persons' processing technology, so employed raw material thickness can reduce greatly under the condition that does not reduce intensity, and have traditional plate deep processing to become the continuous automatic moulding of coiled strip, thereby can be on the unit consumption of material, reduced cost on the utilization ratio of material and on the quantity in stock of material; Owing to the configuration of high automation, aspect manpower, also reduced cost, reduced labor intensity simultaneously.With slot type crane span structure 600*150 is example, from under expect moulding, traditional mode of production on average needs 10 people can produce 200 meters every day, need 5 people can produce 800 meters then average every day with this production line production, obviously therefrom can make comparisons, reduced in 50% in human cost, output has increased by 300%.Save the handing-over of the transhipment between each procedure under the traditional mode of production mode simultaneously, greatly reduced labor intensity.

The new production line is owing to be the continuous automatic moulding of coiled strip, and speed reaches 3～3.5m/min, and manufacturing efficiency is greatly improved, thereby output also is greatly improved, has shortened manufacture cycle and lead time; Since a lot of artificial factor when having got rid of traditional plate deep processing, thus machining accuracy greatly improved, and then guaranteed the quality of product.

Embodiment

Referring to Fig. 1, Fig. 2, shown in, once-through slot type cable testing bridge is by bottom punching beading, trough rim punching, last roll-in beading, bending and molding.The production process of slot type crane span structure from unreel, smoothing, feeding, punching, beading, cut-out, discharging, all be achieved to roll-forming by new, the complete cable testing bridge production line of a cover.Divide three kinds of the little limit of flat sideband, the curved muscle of flat sideband, the curved muscle of flat sideband and stiffening ribs again from side in form.

Claims

1. once-through slot type cable testing bridge, form by bottom land (1), stile (2), curved muscle (3), stiffening rib (4), little limit (5), it is characterized in that curved muscle is the muscle that stile top is hook type, stiffening rib is a twice arched ribs on the stile, and little limit is the limit that stile top is " one " font.
