Abstract
Description
Technical Field
[0001] The utility model relates to a steel rail conveying device, belonging to the field of steel rail processing. Background Art
[0002] After the surface strengthening treatment of the rails, they are sandblasted. Sandblasting can eliminate the local stress caused by the high-temperature plasma on the rail strengthening treatment. During the surface strengthening treatment and sandblasting treatment of the rails, the rails need to be conveyed. In order to prevent the rails from deflecting during the conveying process, it is necessary to set limit rollers in contact with the rails on both sides of the rails. Since the width of the rails is small, the spacing between the limit rollers on both sides of the rails is also small. In order to facilitate the conveying of the rails, rollers need to be set at the bottom of the rails. At present, the relative position of the rollers and the rails is fixed. Affected by the spacing between the limit rollers on both sides of the rails, the rails are only in contact with a part of the rollers. When the contact part between the rollers and the rails is worn and needs to be replaced, other parts of the rollers are not worn because they are not in contact with the rails, resulting in a low utilization rate of the rollers. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a rail conveying device to solve the problems raised in the above-mentioned background technology. The utility model fully utilizes the rollers and reduces the replacement frequency of the rollers.
[0004] The cam is provided with a plurality of movable parts, and the movable parts are provided with a plurality of movable parts, and the movable parts are provided with a plurality of movable parts.
[0005] Furthermore, the driving member includes a first hydraulic cylinder, which is installed on the upper surface of the top plate. The movable end of the first hydraulic cylinder extends to the lower side of the top plate and is connected and fixed to a U-shaped frame. A driving wheel driven by a motor for driving the movement of the rail is rotatably installed in the U-shaped frame.
[0006] Furthermore, a vertical hole is opened in the middle of the upper surface of the top plate, and the movable end of the first hydraulic cylinder passes through the vertical hole.
[0007] Furthermore, the cylinder end of the second hydraulic cylinder is connected and fixed to the support plate, the upper surface of the support plate is provided with a through hole, the movable end of the second hydraulic cylinder passes through the through hole, and the support plate is connected and fixed to the side plate.
[0008] Furthermore, the cross section of the guide groove is in a dovetail shape, and the cross section of the guide block is in a dovetail shape.
[0009] Furthermore, both ends of the limiting roller are rotatably connected to a second bearing seat, and the second bearing seat is fixedly connected to the side plate by screws.
[0010] Beneficial effects of the utility model:
[0011] 1. Adjust the position of the roller along the guide groove. At this time, the guide block slides in the guide groove, that is, the relative position of the roller and the rail between the two relative limiting rollers changes, so that different parts of the roller can contact the rail. When the position of the roller meets the needs, the positioning screw can be used to limit the relative position of the first bearing seat and the support plate, so as to make full use of the roller and reduce the replacement frequency of the roller.
[0012] 2. Control the second hydraulic cylinder to extend or contract, so that the height of the support plate changes. At this time, the relative position of the roller and the limiting roller changes. Under the support of the roller, the rail contacts different parts of the vertically arranged limiting roller. After a certain area of the limiting roller is worn, the rail moves to the unworn area of the limiting roller, which is beneficial to improve the utilization rate of the limiting roller and reduce the replacement frequency of the limiting roller.

Both ends of the limiting rollers 8 are rotatably connected to the second bearing seats 5. The second bearing seats 5 are fixed to the side plates 12 by screws. The second bearing seats 5 play the role of connecting the limiting rollers 8 and the side plates 12. Under the restriction of the limiting rollers 8, the moving trajectory of the rails is restricted.
