The working process and principle of the utility model
As shown in fig. 5, the two-way hydraulic combination driving type locking beam (hereinafter referred to as locking beam) of the present invention is installed on the seat plate 22 at both ends of the trash rack groove 21, and a pair of hinge seats 24 is installed on one side of the seat plate 22 close to the trash rack pull rod 23. When the locking beam 1 is installed, firstly, the sliding strip 15 at the bottom of the locking beam 1 is located on the seat plate 22, and the bottom surface of the sliding strip 15 is an arc surface 16 so as to reduce the friction resistance between the locking beam 1 and the seat plate 22. And then one end of the hydraulic cylinder of the horizontal hydraulic machine 5 at the two ends of the locking beam 1 is hinged with the hinged support 24. The locking beam 1 can be pulled towards the trash rack pull rod 23 or the locking beam 1 can be pushed away from the trash rack pull rod 23 by the horizontal hydraulic press 5 at both ends of the locking beam 1. The trash rack pull rod 23 is provided with a locking seat plate 25, and the locking seat plate 25 is provided with a locking hole 26. When the trash rack needs to be locked, the trash rack pull rod 23 connected with the trash rack is pulled up to a height that the locking base plate 25 of the trash rack pull rod exceeds the top surface of the upper wing plate 6 of the locking beam 1 by a hoisting device. The locking beam 1 is then pulled towards the trash rack tie rods 23 by the horizontal hydraulic press 5 at both ends of the locking beam 1 shown in fig. 1, so that the pin shaft through holes 4 on the locking beam 1 are aligned with the locking holes 26 on the locking seat plate 25, and then the trash rack tie rods 23 are slowly placed on the locking beam 1. And then, the external thread 20 at the small-diameter end of the stepped pin shaft 3 is ejected out and inserted into a locking hole 26 on a locking seat plate 25 through the vertical hydraulic machine 2, and the locking seat plate 25 on the trash rack pull rod 23 and the locking beam 1 are connected into a whole through a nut 27 to complete the locking operation, wherein the locked structure is shown in fig. 6. Because the locking base plate 25 on the trash rack pull rod 23 is connected with the locking beam 1 into a whole, the locking firmness is enhanced, the trash rack cannot overturn, and the locking safety of the trash rack and the trash rack pull rod is effectively guaranteed.
When the trash rack pull rod 23 needs to be unlocked, firstly, the nut 27 at the small-diameter end of the step-type pin shaft 3 is removed, then the vertical hydraulic machine 2 pulls the small-diameter end of the step-type pin shaft 3 to be contracted into the pin shaft penetrating hole 4, the lifting equipment is adopted to lift the trash rack pull rod 23 away from the locking beam 1, the horizontal hydraulic machine 5 pushes the locking beam 1 away from the trash rack pull rod 23, and then the trash rack fixed at the lower end of the trash rack pull rod 23 is placed at a trash rack position through the lifting equipment. In the whole locking and unlocking process, the locking beam 1 is pulled or pushed by the horizontal hydraulic machines 5 at the two ends of the locking beam 1, so that the labor is saved, and the locking beam 1 is stable in movement, simple to operate and convenient to operate.
