Detailed Description

The present invention is further illustrated by the following examples, but is not limited to the contents of the specification.

As shown in the figure: a long steel rail lifting and turning device comprises a steel rail 1, a roller bed 2, a fixing support 3, a turning hydraulic cylinder 4, a lifting hydraulic cylinder 5, a guide rod 6, a connecting plate 7 and a turning plate 8.

Rail 1 sets up on roll table 2, fixed bolster 3 sets up between roll table 2, hydraulic cylinder 5's one end is fixed on fixed bolster 3, the cross-section of connecting plate 7 is the L type, it includes supporting part 71 and connecting portion 72, hydraulic cylinder 5's the other end articulates in the bottom of supporting part 71, supporting part 71's top articulates there is returning face plate 8, returning face plate 8's cross-section is the L type, connecting portion 72 is fixed at returning face cylinder 4's middle part, returning face cylinder 4's one end passes through connecting rod 41 and articulates in the bottom of returning face plate 8, returning face cylinder 4's other end slidable fixes on fixed bolster 3, the one end slidable of guide bar 6 is installed on fixed bolster 3, the bottom at supporting part 71 is fixed to.

Fixed bolster 3 and the equipment foundation of tilting gear link to each other, and fixed bolster 3 and hydraulic cylinder 5 hard coupling lift, hydraulic cylinder 5, upset pneumatic cylinder 4, returning face plate 8 are articulated with connecting plate 7, and connecting

plate

7 and 6 hard couplings of guide bar, 6 slides of guide bar and passes fixed bolster 3.

After the steel rail 1 is stopped and stabilized on the roller table 2 (figure 1), a lifting hydraulic cylinder 5 fixed on a fixed support 3 extends to drive a turnover hydraulic cylinder 4, a guide rod 6, a connecting plate 7 and a turnover plate 8 to ascend (a first step-figure 2); after the steel rail rises to the right position, the turnover hydraulic cylinder 4 contracts and drags the turnover plate 8 to rotate, and the steel rail 1 is forced to turn over by an angle of 90 degrees (the second step-shown in figure 3); the lifting hydraulic cylinder 5 contracts to drive the turnover hydraulic cylinder 4, the guide rod 6, the connecting plate 7 and the turnover plate 8 to descend (a third step-shown in figure 4); in the descending process, the turnover hydraulic cylinder 4 extends to return the turnover plate 8 to the return position (the fourth step-figure 5), and a motion cycle is completed.

This neotype beneficial effect: 1. the rail is turned 90 degrees by hydraulic action. 2. And (4) turning steel by adopting step-by-step combined action. 3. Simple structure, simple operation and reliable process. 4. Full automatic operation can be realized. The operation efficiency is improved, the production accident rate is reduced, the annual economic benefit is 300 ten thousand yuan, the field process condition is improved, the energy is saved, and the economic benefit can be created by more than 60 ten thousand yuan.

It is to be understood that the above-described embodiments of the present invention are merely examples provided for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
