Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, a track slab gantry crane comprises a hanger 1, a lifting mechanism 2 and a connecting mechanism 3, wherein one end of the connecting mechanism 3 is connected with a track slab, the other end of the connecting mechanism 3 is controlled to lift by the lifting mechanism 2, the connecting mechanism 3 mainly comprises a connecting seat 31, a lifting lug 33 and a connecting piece 32 for connecting the connecting seat 31 and the lifting lug 33, the lifting lug 33 is installed on a bolt hole of the track slab through a bolt, the connecting piece 32 is detachably fixed between the connecting seat 31 and the lifting lug 33, the device is generally used for lifting the track slab in a group two by two, the track slab is lifted in front of and behind, and the track slab is laid at a designated position simultaneously by moving, when the track slab is lifted, the lifting lug 33 is fixed in the corresponding bolt hole of the track slab, the hanger 1 is moved above the lifting lug 33, the lifting lug 33 and the connecting seat 31 are connected through the connecting piece 32, at the moment, the track slab can be lifted off the ground through the lifting mechanism 2, remove gallows 1 and make the track board reach the assigned position, rethread elevating system 2 transfer the track board can, convenient dismantlement between connecting piece 32 and connecting seat 31, the lug 33 not only is convenient for connect the track board, still conveniently changes after connecting piece 32 damages.
Connecting piece 32 is the steel chain, sets up through-hole 312 on the connecting seat 31, and the steel chain is through passing through-hole 312 and lug 33 constitution coupling mechanism 3, and the steel chain is under lax state, and the chain rocks easily, but along with elevating system 2 lifts up the track board, and the steel chain is in tight state, just difficult rocking, improves the stability of hoist and mount, and connecting piece 32 is not restricted to the steel chain, can also use rigid structure, and specific use method can adjust according to the site operation situation.
The lifting mechanism 2 is a worm screw lifting machine 21 and is connected with the connecting base 31 through the lifting screw 22, as shown in fig. 3, the top end of the connecting base 31 is provided with a thread groove 311, the connecting base 31 is in threaded connection with the lifting screw 22 through the thread groove 311, the connecting base 31 can be conveniently disassembled and assembled with the lifting screw 22 through the thread groove 311, and the replacement is convenient after the damage and deformation.
