Description

Technical Field

[0001] The utility model belongs to the technical field of bearing devices of limiters, and in particular relates to a multifunctional bearing device of limiters. Background Art

[0002] The scrap buckets, ladle cross-cars or transport vehicles in steel plants all run on tracks. When parking, they need to be stopped by a limiter. In actual use, it is sometimes necessary to adjust the position of the limiter according to the production situation. For example, in order to facilitate loading and unloading, the parking position should be at the best loading and unloading position. At this time, the limiter needs to be moved horizontally, or the loaded object exceeds the transport vehicle. At this time, the edge of the object should be used as the trigger point, so the limiter needs to be moved vertically for parking. The existing operation is to install the limiter on a lifting rod with a base. When the position needs to be adjusted, the lifting rod is moved between the tracks, and the vertical position is adjusted by adjusting the height of the lifting rod. This method has safety hazards. It is not only laborious for people to move back and forth, but also there is a risk of tripping. In addition, the lifting rod is not firmly fixed and can be easily knocked over, resulting in parking failure. Summary of the invention

[0024] The utility model will now be further described in detail with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a multifunctional limiter 10 bearing device includes a support 1, a strip groove 2 is opened on one side of the support 1, a rotating slide rod 3 is connected to the bearing on the support 1, and the two ends of the rotating slide rod 3 are connected to the screw rod 4 through the bevel gear 19, the screw rod 4 bearing is connected to the support 1, the screw rod 4 is threaded with a support column 6, and a lifting column 7 is sleeved on the outer side of the support column 6. The top of the lifting column 7 is welded to the bottom of the support 1, and a slider 8 is slidably connected to the rotating slide rod 3. A sliding plate 8 is installed on the slider 8, and a limiter 10 is installed on the sliding plate 8. The limiter 10 is provided with a power cord 11, and an electric wire slide rod 12 is welded on the support 1. The power cord 11 passes through the sliding plate 8 and is hung on the electric wire slide rod 12. A rotating handle 5 is welded to one end of the rotating slide rod 3, and the rotating handle 5 is connected to the support 1 through a pin 20.

[0026] The support 1 includes two side plates 13, between which two first vertical plates 14, two second vertical plates 15, and two bottom plates 16 are welded. The two first vertical plates 14 are symmetrically located at both ends of the side plates 13, the two second vertical plates 15 are symmetrically located between the two first vertical plates 14, and the bottom plate 16 is located at the bottom ends of the first vertical plates 14 and the second vertical plates 15.

[0027] The two ends of the rotating slide bar 3 are respectively connected to the two first vertical plates 14 of the support 1 by bearings, the rotating slide bar 3 passes through the two second vertical plates 15, the two ends of the wire slide bar 12 are respectively welded to the two second vertical plates 15 of the support 1, and the screw rod 4 is connected to the bottom plate 16 of the support 1 by bearings. The rotating slide bar 3 drives the screw rod 4 to rotate through the bevel gear 19, and the screw rod 4 is threadedly connected to the support column 6, so that the screw rod 4 moves upward or downward on the support column 6.

[0028] The bottom end of the sliding plate 8 is close to the top ends of the two side plates 13 to prevent the slider 8 from rotating on the slide rod.

[0029] The slider 8 is a slider 8 with a locking device. The strip groove 2 is located on the side plate 13 close to the locking end of the slider 8. The locking end of the slider 8 passes through the strip groove 2 to facilitate locking of the slider 8.

[0030] The rotating handle 5 is provided with a through hole 21 , and the first vertical plate 14 close to the rotating handle 5 is provided with a through hole 21 . Both ends of the pin 20 are respectively connected to the through holes 21 on the rotating handle 5 and the first vertical plate 14 .

[0031] A retaining ring 22 is welded on the pin shaft 20 between the rotating handle 5 and the first vertical plate 14 .

[0032] The support column 6 is hollow inside, and an inner thread hole 17 is opened at the top. The screw rod 4 is threadedly connected to the inner thread hole 17 and then penetrates into the support column 6.

[0033] A plurality of S hooks 18 are slidably mounted on the wire slide bar 12, and the power cord 11 is fixed on the S hooks 18, and the power cord 11 is mounted on the wire slide bar 12 through the S hooks 18. Since the power cord 11 is relatively long, when the slider 8 slides, it is easy to drag the power cord 11, causing the power cord 11 to be worn. At the same time, the power cord 11 is easy to slide onto the track when it is bent on the ground, and is easy to be crushed by the track wheels, causing safety accidents. When the slider 8 moves on the rotating slide bar 3, the slider 8 pushes or pulls the S hooks 18 to slide on the wire slide bar 12, so that the power cord 11 can be folded or stretched as the slider 8 moves, thereby preventing the power cord 11 from being dragged on the ground and causing the power cord 11 to be worn, and preventing the power cord 11 from sliding onto the track.

[0034] The working principle of the utility model is:

[0035] When in use, the utility model is installed on one side of the track, and the trigger rod of the limiter 10 is facing the track. When the limiter 10 needs to be moved horizontally, the locking device of the slider 8 is loosened, the limiter 10 is moved to a suitable position, and then the locking device is locked, thereby completing the adjustment of the horizontal position of the limiter 10.

[0036] When vertical adjustment is required, the locking device of the slider 8 is released, and the pin 20 is pulled out of the through hole 21 of the first vertical plate 14. At this time, the pin 20 is held and the rotating handle 5 is turned. The rotating slide bar 3 drives the screw rod 4 to rotate through the bevel gear 19. The screw rod 4 is threadedly connected to the support column 6, so that the screw rod 4 moves up or down on the support column 6. Since both screw rods 4 are driven by the rotating slide bar 3, the movements of the two screw rods 4 are synchronized, thereby realizing the overall lifting and lowering of the support 1. After adjustment, the pin 20 is inserted into the through hole 21 of the first vertical plate 14 again to fix the rotating slide bar 3 and complete the adjustment in the vertical direction.

[0037] When the slider 8 moves on the rotating slide bar 3, the slider 8 pushes or pulls the S hook 18 to slide on the wire slide bar 12, so that the power cord 11 can be folded or stretched as the slider 8 moves, thereby preventing the power cord 11 from being dragged on the ground and causing the power cord 11 to be worn.
