Description

A kind of coil grab

Technical field

The utility model relates to suspender, belongs to the cold and hot manufacturing line coil grab that rolls especially, is particularly useful for producing high-end automobile and household electrical appliances with coil grab in the cold rolling finished product volume.

Background technology

As the most important household electrical appliances of cold rolling mill with plate and high-end automobile with each unit of board assembly line, in operation production process up and down, need carry out the logistics transportation to coil of strip with coil grab through regular meeting.The present common coil grab device that adopts, as shown in Figure 1, wherein A is a coil of strip, and its agent structure is " C " shaped steel volume suspender, because the restriction of its constructional feature, this suspender in use, main existing problems are that operating radius is big, when suspender hangs centering volume core, must there be the collaborative commander of special messenger operation on ground, and push-and-pull coil of strip labour intensity is big, breaks coil of strip volume core and limit portion during " C " type suspender contact; And for example shown in Figure 2, it is a kind of coil grab of hydraulic cylinder type, say it is to make clamp clamp coil of strip A definitely by stretching of hydraulic actuating cylinder B, though operating radius makes moderate progress, but because hydraulic actuating cylinder only is equipped with shock absorber at original retracted position and full extended position, can make the slow fore and aft motion of hydraulic stem, all the other positions all do not have pooling feature, because the different width of coil of strip, clamping coil of strip by buffer position before and after the hydraulic actuating cylinder may realize hardly, often when clamping coil of strip, hydraulic clamp often is in midway location because of hydraulic cylinder piston rod, bump coil of strip dual-side portion takes place, make the impaired coil of strip of limit portion, in addition, bump also makes the shortening in service life of coil grab clamp, functions of use descends, frequent and the service expenditure height of maintenance, the high-altitude chaufeur is difficult to centering hydraulic hanger aligning coil of strip volume core hole simultaneously, occurs hydraulic hanger clamp head impact coil of strip volume core often, cause material unaccounted-for (MUF), the rate of becoming a useful person reduces, and in the end a step finishing rewinding unit then takes to stay the tail volume number of turns to the scuffing problem of volume core more, above problem has hindered present enterprise and has pursued high quality, the serialization production and operation pattern of high benefit has hindered the raising of business economic benefit.The limitation of existing coil grab device is: 1. " C " shaped steel volume suspender operating radius is big, ground needs the operating personnel to cooperate, and labour intensity is big, and 2. hydraulic pressure coil grab is because the technical limitation of hydraulic actuating cylinder own, there is not buffer capacity in the telescopic process, when hydraulic actuating cylinder in contraction process, the suspender clamp is pressed close to the steel flanging part and all will be clashed into, make the steel flanging part because of clashed into be out of shape impaired, keep in repair frequent and service expenditure height, influence the production economic benefit of enterprise.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of coil grab, and its displacement is accurate, can prevent that the steel flanging part is out of shape impairedly because of clashing into, and increases work efficiency.

For solving the problems of the technologies described above, purpose of the present utility model is achieved in that a kind of coil grab, comprises two clamps, and clamp comprises holder arms and hook portion; One hangs crossbeam; Be fixed on two curb girders that are oppositely arranged that hang the crossbeam side, curb girder is provided with the parallel motion groove; Pair of bearing is fixed on and hangs the crossbeam two ends; Revolve the double-threaded screw screw mandrel about one, be installed in the bearing seat; One CD-ROM drive motor and reduction gear apparatus are connected with the double-threaded screw screw mandrel; Described clamp is provided with internal thread hole, and the screw thread with screw mandrel two is connected respectively; Also be provided with the parallel motion locating part on each clamp, this parallel motion locating part is walked in the parallel motion groove of curb girder.

Preferably, the medial surface of holder arms is provided with a pair of apomecometer.

Preferably, the medial surface of clamp hook portion is provided with video camera.

Preferably, described curb girder is " L " shape curb girder, and described parallel motion groove is the inner bottom surface of " L " shape.

Preferably, described parallel motion locating part is the road wheel that is installed on the clamp.

Preferably, also be provided with roller on the clamp, this roller contacts with the side of " L " shape curb girder.

Preferably, the quantity of described road wheel and roller is one at least 2 pair.

Preferably, described " L " shape curb girder inner bottom surface is provided with abrasion-proof backing block.

Preferably, described CD-ROM drive motor is the frequency conversion drive motor, places on the top that hangs crossbeam.

Preferably, described reduction gear apparatus is a gear transmission, and double miniature gears is housed on the CD-ROM drive motor spindle nose, and double-threaded screw screw mandrel one side is equipped with double big gear wheel, and double miniature gears is connected by double metallic bond with double big gear wheel.

The utility model improve designed suspension crossbeam, " L " shape curb girder, about revolve the double-threaded screw screw structure, and adopted video camera, infrared ray side apart from instrument.Compared with prior art, its beneficial effect is: displacement is accurate, has eliminated the bump in coil of strip clamp and the coil of strip outside, has reduced the loss of steel flanging part, has improved unit production recovery rate.Use the infrared ray side apart from instrument and video camera, gripper jaws can correctly be pressed close to the coil of strip both sides fast, and the centering coil of strip is rolled up core fast, has improved work efficiency.Can still can bring into play efficiently work rhythm accurately not being equipped with under the ground staff commander, integrate limited human resources.
