Such as Fig. 1-Fig. 3, a kind of precast beam lifts anti-chipping instrument, on the precast beam 3 lifted applied to straddle truck 1, with showing
Have that technology is identical, the both ends of straddle truck 1 are erected on gantry crane rail 2, i.e., straddle truck 1 by wheel on gantry crane rail 2
It is mobile.The precast beam, which lifts anti-chipping instrument, includes angle steel 5, steel collar 6 and rubber blanket 7, and angle steel 5 can be equal leg angle
Can be unequal angle, the angle steel in the present embodiment preferably is equal leg angle, a length of 50cm of selected equal leg angle,
Hem width is 100mm, and side thickness is 10mm.The angle steel 5 is equal leg angle, and the steel collar 6 is among the axis of the angle steel 5
On the corner of position, the shape of the rubber blanket 7 is identical with the shape of the angle steel 5, and the one side of the rubber blanket 7 is close to institute
The inwall of angle steel 5 is stated, the another side of the rubber blanket 7 contacts with the corner angle of the precast beam 3.Institute is lifted on the straddle truck 1
The steel wire rope 4 for stating precast beam 3 passes through the steel collar 6, and the precast beam is lifted into anti-chipping instrument is fixed on for lifting
On the steel wire rope 4 of the precast beam 3, make it have long-term revolving.
Further, the internal diameter of the steel collar 6 is 8-10cm, so that the internal diameter size of steel collar 6 and steel wire rope is outer
Footpath size is adapted.The internal diameter of steel collar 6 is preferably 8cm in the present embodiment.
Further, the thickness of the rubber blanket 7 is 15-17mm, by using the rubber blanket 7 of suitable thickness, is not only made
Rubber blanket 7 fully plays cushioning effect, can also prevent rubber blanket 7 because thickness is too small and easy to wear bad, because thickness is excessive and caused by
Gravity is excessive, the problems such as bonding loosely.The thickness of rubber blanket 7 described in the present embodiment is preferably 15mm.
The manufacturing process that the present embodiment precast beam lifts anti-chipping instrument is：
(1) from long 50cm, hem width 100mm, side thickness 10mm angle steel 5,5 preferred hot rolling equal angle steel of angle steel；
(2) steel collar 6 for being 8cm in the corner in the axis centre position of angle steel 2 welding internal diameter, straddle truck 1 is lifted by crane
Steel wire rope 4 pass through steel collar 6；
(3) rubber blanket 7 that thickness is 15mm is bonded in the inwall of angle steel 5 so that rubber blanket 7 directly connects during lifting
The surface of precast beam 3 is touched, precast beam 3 is played a protective role.
During use, the anti-chipping instrument of the utility model is enclosed on by steel collar 6 on the steel wire rope 4 of the lifting of straddle truck 1,
Ensure in long-term use, anti-chipping instrument has long-term revolving, will not lose.Utilizing the hoisting prefabricated beam 3 of straddle truck 1
When, the steel wire rope 4 of lifting is enclosed on to the lifting position of precast beam 3, angle steel 5 is abutted against to the edges and corners of precast beam 3, makes rubber blanket
7 contact with the surface of precast beam 3.When straddle truck 1 lifts precast beam 3, the stress of steel wire rope 4 is exceptionally straight, and extruding force is produced to precast beam 3,
Angle steel 5 and rubber blanket 7 are uniformly spread extruding force by increasing the lifting surface area to the beam body of precast beam 3, reduce precast beam 3 by
The stress arrived, so as to ensure that, local chipping will not occur for precast beam 3 in hoisting process, it is ensured that the apparent matter of precast beam 3
Amount and structure durability.
Angle steel 5 of the present utility model adds the contact with precast beam 3 of steel wire rope 4 of straddle truck lifting in use
Area, the stress suffered by precast beam 3 is reduced, prevent the beam body corner of precast beam 3 from bursting apart.Simultaneously by angle steel 5
Wall has set the rubber blanket 7 of cushioning effect, further ensure that the surface of precast beam 3 and will not be burst apart due to lifting.And this reality
Steel collar 6 is provided with new, during hoisting prefabricated beam is repeated using straddle truck 1, anti-chipping instrument can pass through steel bushing
Ring 6 links together all the time with the steel wire rope 4 lifted by crane, improves the rate of being used in turn, and solves the anti-chipping instrument of tradition and easily occurs
The problem of damage is with losing.
Described above is the detailed description for the preferable possible embodiments of the utility model, but embodiment is not limited to
Patent claim of the present utility model, the equal change or modification completed under the technical spirit suggested by all the utility model
Change, all should belong to the utility model and cover the scope of the claims.
