Detailed Description
The invention is described in further detail below with reference to the following figures and specific embodiments:
the invention discloses a groove-drop preventing device for a connecting rod of a tilting gear, which is used in the continuous casting production process. The tail part of the connecting rod 4 is hinged with a connecting rod base 5, and the connecting rod base 5 is a shell with a U-shaped section. The anticreep groove device is including fixing device base 1 at connecting rod 4 afterbody terminal surface, the both sides face of device base 1 is fixed respectively and is set up the clearance adjustment device who adjusts the distance between connecting rod base 5 and the device base 1, clearance adjustment device's axis is perpendicular with the axis of connecting rod 4. The specific structure is shown in fig. 1.
In the specific implementation, the gap adjusting means have different arrangements, two of which are specifically described below.
Example 1
The gap adjusting device in this embodiment includes a lead screw 3 and a stopper nut 2. A through threaded hole 1-1 is formed in the center of the side face of the device base 1, and the specific structure is shown in fig. 4. The two screw rods 3 are respectively screwed into the threaded holes 1-1 from the two ends of the threaded holes 1-1, and the initial state is preferably set in such a way that the screwing depth of the two screw rods 3 into the threaded holes 1-1 is half of the length of the threaded holes 1-1. Stop nuts 2 are arranged on the two screw rods 3, and the stop nuts 2 are positioned at the bottom ends of the parts, exposed out of the threaded holes 1-1, of the screw rods 3 and are tightly contacted with the side surface of the device base after being screwed in a working state, and the specific structure is shown in figures 1 and 2. The number of the stop nuts 2 on each screw rod 3 is preferably set to 2. The length of the two screw rods 3 is 1/3-2/5 of the distance between the inner walls of the connecting rod bases 5, and the arrangement limits the gap between the screw rods 3 and the inner walls of the connecting rod bases 5, namely the gap between the connecting rod 4 and the inner walls of the connecting rod bases 5, so that the transverse moving range of the connecting rod 4 in the connecting rod bases 5 is ensured to be fixed in a certain numerical range, the transverse moving range of the connecting rod 4 is ensured, and the connecting rod is prevented from being separated from the groove. Fig. 3 is an exploded view of the separation preventing means in this embodiment, showing the respective parts in an exploded state.
The adjustment process of the backlash adjustment mechanism in this embodiment is as follows: after the tilting gear works for a period of time, the pin shaft part of the connecting rod 4 is abraded, and the connecting rod has large transverse swing. At this time, the screw rod 3 is screwed outwards, so that the distance between the end of the screw rod 3 and the inner wall of the connecting rod base 5 is within a proper range, usually 5-10 mm, and the specific schematic diagram is shown in fig. 5. When the screw rods 3 are adjusted in place, the stop nuts 2 are screwed to the bottom ends of the parts exposed out of the threaded holes 1-1, and the two stop nuts 2 on each screw rod 3 are screwed in place to keep the screw rods 3 in a fixed state. When the gap needs to be adjusted again, the above process is repeated.
The gap adjusting device is formed by combining the screw rod and the threaded hole, and is simple in structure, easy to realize, large in bearing acting force and stable and reliable in work.
Example 2

In order to accurately adjust the distance between the hydraulic telescopic rod 6 and the inner wall of the connecting rod base 5, a distance measuring sensor is arranged at the outer end part of the telescopic section 6-2 of the hydraulic telescopic rod 6, and the distance measuring sensor can feed measured data back to a hydraulic system.
The adjustment process of the backlash adjustment mechanism in this embodiment is as follows: after the tilting gear works for a period of time, the pin shaft part of the connecting rod 4 is abraded, and the connecting rod 4 has large transverse swing. At this time, the hydraulic system controls the telescopic section 6-2 of the hydraulic telescopic rod 6 to extend and retract outwards, and meanwhile, the distance measuring sensor can closely pay attention to the measured data, when the distance between the end part of the telescopic section 6-2 of the hydraulic telescopic rod 6 and the inner wall of the connecting rod base 5 is in a proper range, usually 5-10 mm, the movement of the telescopic section 6-2 is stopped, and the position is kept still. When the gap needs to be adjusted again, the above process is repeated.
