The technical scheme of the utility model as follows:

The frog air turnover device comprises a hanging beam and a sling; the lifting beams are arranged in a bilaterally symmetrical and parallel manner, are matched in pairs for use, the upper parts of the middle sections of the lifting beams are fixedly provided with upper lifting rings capable of being hung on a lifting hook of a crane, and the lower parts of the lifting beams are fixedly provided with at least two or more lower lifting rings for hanging the lifting ropes; the sling cables are also used in pairs, namely at least two sling cables are paired to form a uniform tucking frog each time; and two ends of each sling are respectively detachably connected between the lower lifting rings at the lower parts of the lifting beams which are matched in pairs.

The frog air turning device, wherein: each sling is of a flexible sling structure and consists of a flat sling and two eye-encircling lifting hooks connected to two ends of the sling in a matching manner; and two ends of the hanging strip are hung on the lower hanging ring at the lower part of the hanging beam through the ring eye hanging hooks respectively.

the frog air turning device, wherein: the sling can adopt an iron chain or a cloth belt.

The frog air turning device, wherein: each hanging beam is made of steel section with a rectangular section.

Has the advantages that:

The utility model utilizes the air turning device of the frog to turn the frog, so as to improve the working efficiency and better adapt to the railway construction requirement of high-speed development; the frog is wrapped by two suspension cables at the same time, so that the frog has the advantages of stable turnover, stable operation, small impact and noise, no collision in the air due to the turnover of the flexible suspension cable, small impact on a matched crane and safe and reliable use.

the utility model can be controlled by the crane electrically or remotely, has high working efficiency, meets the railway construction requirement of high-speed development, and has the characteristics of stable turnover, stable operation and small impact and noise; the frog is turned over in the air by being wrapped by two flexible suspension cables without collision; the impact on a matched crane is small, and the use is safe and reliable; according to the length of the frog, the lower hanging rings at the proper positions of the lower part of the hanging beam can be symmetrically selected to hang the suspension cables so as to turn over the frog with different lengths and specifications, so that the frog is turned over in the air and stressed evenly and reliably, and is not easy to collide, and the frog can be placed at a specified position by the way after being turned over, so that the frog is safer and more reliable than the original frog.

Detailed Description

As shown in fig. 1 and 2, the utility model discloses a frog air turning device, including hanging beam 1 and hoist cable 2.

The hanging beams 1 are a pair of hanging beams which are arranged in parallel and are bilaterally symmetrical, and the hanging beams 1 are matched in pairs and are made of steel sections with rectangular sections; wherein, the upper part of the middle section of the pair of hanging beams 1 is fixedly provided with an upper hanging ring 11 which can be hung on a crane hook, and the lower part of the pair of hanging beams 1 is uniformly and fixedly provided with 5 lower hanging rings 12 for hanging the hanging ropes along the length direction.

The sling 2 is a flexible sling connected between lower rings 12 at the lower parts of a pair of hanging beams 1, and each sling 2 consists of a flat sling 21 (the sling can be an iron chain or a cloth belt) and two ring eye hooks 22 connected at the two ends of the sling 21 in a matching way; wherein, every time, two slings 2 are paired to form a uniform frog 3, and two ends of a sling 21 of each sling 2 are hooked on the lower lifting rings 12 at the lower sides of a pair of lifting beams 1 through eye lifting hooks 22; in practical application, the lower hanging ring 12 at the lower part of the hanging beam 1 can be symmetrically selected to hang the suspension cable 2 according to the length of the frog 3.

As shown in fig. 3, the method for realizing the turnover of the frog 3 in the air by using the turnover device in the air of the frog 3 of the present invention comprises: two sets of hoisting mechanisms of a matched crane respectively hang and hang one hoisting beam 1, lower hoisting rings 12 at the lower part of the hoisting beam 1 are symmetrically selected to hang and hang hoisting ropes 2 according to the length of frog 3, and after the frog 3 is uniformly hung and hung by two flexible hoisting ropes 2, the hoisting ropes are symmetrically hung on the lower hoisting rings 12 at the corresponding positions at the lower part of the hoisting beam 1; the two lifting beams 1 are positioned at two sides of the frog 3, and simultaneously lift to lift the frog 3 to a certain height from the ground; one lifting beam 1 is lifted by a crane, the other lifting beam 1 is lowered by the crane, and the two slings 2 are used for repeatedly operating so as to realize the turnover of the frog 3 in the air.

this embodiment is used double hook bridge crane to hang the utility model discloses 3 aerial turning device hoist and mount frogs of frogs 3, frogs 3 are being overturned by 2 pockets of two flexible hoist cables aloft, according to the length of frogs 3, but suspension cable 2 is hung to the lower rings 12 that the corresponding position in 1 lower part of symmetric selection hanging beam, and the frogs 3 of the different length of upset make frogs 3 evenly reliable at the aerial upset atress, non-deformable, place assigned position with frogs 3 after the upset incidentally.

The utility model has the advantages of simple and reasonable design, can obviously promote the security of hoist and mount, there is not the frog to collide with among the turnover process, and very little to supporting hoist impact that uses, equipment fault rate reduces by a wide margin.
