And cross-shaped limiters are further arranged on the trolley running track I and the trolley running track II.

And the trolley operation track I is also provided with a track-passing alignment limit.

Compared with the prior art, the utility model discloses following beneficial effect has:

when the trolley operation track I and the trolley operation track II are aligned, the locking block is pushed to the groove of the trolley operation track I only by pulling the connecting rod through the handle, the lug of the locking block is clamped in the groove, and the insertion sheet is inserted into the slot to complete the rail connecting operation, so that the use is convenient; in addition, the cross-shaped limiting stopper can prevent the problems of derailment and dislocation and the like when the cart or the trolley runs.

Description of the drawings:

fig. 1 is a schematic structural view of an improved crane track structure of the present invention;

FIG. 2 is a schematic view of the junction between the first trolley running track and the second trolley running track;

the reference signs are: the device comprises a 1-moving track device, a 11-cart running track, a 12-trolley running track I, a 121-groove, a 2-fixed track device, a 21-trolley running track II, a 31-limiting block, a 311-inserting sheet, a 32-locking block, a 321-convex block, a 322-slot, a 33-connecting rod device, a 34-handle, a 4-cross limiting device and a 5-rail-crossing alignment limiting device.

The specific implementation mode is as follows:

the following detailed description of the embodiments of the present invention is provided, but it should be understood that the scope of the present invention is not limited by the embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 1-2, an improved track passing structure of a crane comprises a moving track device 1 and a fixed track device 2, wherein the moving track device 1 is provided with a cart running track 11 and a trolley running track one 12, the fixed track device 2 is provided with a trolley running track two 21, the end surface of the trolley running track one 12 is provided with a groove 121, the trolley running track one 12 and the trolley running track two 21 are locked by a limiting device, the limiting device comprises a limiting block 31, a locking block 32 and a connecting rod device 33, the limiting block 31 is arranged on the trolley running track one 12, the limiting block 31 is provided with an insertion sheet 311, the insertion sheet 311 extends into the groove 121 on the end surface of the trolley running track one 12, the locking block 32 is arranged on the trolley running track two 21, the locking block 32 is provided with a projection 321 matched with the groove 121, the projection 321 is provided with an insertion groove 322 matched with the insertion sheet 311, the link device 33 is connected with the lock block 32, and the handle 34 is connected to the link device 33.

And cross-shaped limiting devices 4 are further arranged on the trolley running track I12 and the trolley running track II 21.

And the trolley running track I12 is also provided with a track crossing alignment limit 5 for detecting whether the track is in an alignment state. When the first rail 12 and the second rail 21 are close to each other, the operation platform is switched to a rail passing state through electric control, the crane runs at a low speed, and after the rail passing alignment limit 5 is triggered, the crane is electrically controlled to stop running, and at the moment, the two rails are in an aligned state.
