Description

Technical Field

[0001] The utility model relates to a rail fixing component, belonging to the field of rail processing. Background Technique

[0002] Through high-temperature plasma strengthening treatment on the top surface of the rail and the inner side surface of the track, the hardness can reach above RHC60, increasing the wear resistance of the rail and prolonging the service life of the rail. After the surface strengthening treatment of the rail, sandblasting treatment is carried out on it. The sandblasting treatment requires collecting the contour data of the rail to determine the difference between the actual height and the standard height. When the rail is collecting data and milling, the rail is fixed, and two clamping plates are respectively clamped on the two side surfaces of the rail. One of the clamping plates is installed on the output end of the hydraulic cylinder, so as to conveniently drive one clamping plate to move by using the hydraulic cylinder. The above method is one of the common methods for restricting the position of the rail. During the contact process between the clamping plate and the rail, there is an extrusion force between the clamping plate and the rail. The end of the clamping plate will be worn due to the influence of the extrusion force and the uneven area on the surface of the rail, resulting in the reduction of the contact area between the worn clamping plate and the rail, affecting the stability of restricting the position of the rail. The cost of replacing the clamping plate as a whole is relatively high. Therefore, it is necessary to design a rail fixing component that realizes local replacement of the easily worn parts. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a rail fixing component to solve the problems put forward in the above background technique. The utility model realizes local replacement of the easily worn parts and reduces the cost of replacing parts.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical solutions: a rail fixing component, including a base, on one side of the upper surface of the base, a fixed clamping plate for clamping the rail is installed. On the upper side of the base, a movable clamping plate for clamping the rail and cooperating with the fixed clamping plate is provided. The movable clamping plate is fixedly connected to the movable end of the hydraulic cylinder, and the cylinder body end of the hydraulic cylinder is fixedly connected to the base. On the upper surface of the fixed clamping plate near the movable clamping plate and on the upper surface of the movable clamping plate near the fixed clamping plate, a plurality of equally spaced plugging grooves are opened. The bottom of the plugging groove is closed, and a plugging block is inserted in the plugging groove. One end of the plugging block outside the plugging groove is provided with an end plate.

[0005] Further, the cross-section of the plugging block is T-shaped, and the cross-section of the plugging groove is T-shaped.

[0006] Further, two supports are symmetrically fixed on the lower surface of the fixed clamping plate, and the lower ends of the supports are fixedly connected to the base.

[0007] Further, a vertical plate is installed on one side of the upper surface of the base away from the fixed clamping plate. A perforation is provided on one side surface of the vertical plate. The movable end of the hydraulic cylinder penetrates through the perforation, and the cylinder body end of the hydraulic cylinder is fixedly connected to the vertical plate by a plurality of screws.

[0008] Further, a lifting plate is installed on the lower surface of the movable clamping plate, and the lower end of the lifting plate is in sliding contact with the base.

[0009] Further, a round hole is provided at the upper part of one side surface of the lifting plate. A horizontally arranged screw rod is inserted into the round hole. Both ends of the screw rod are fixedly connected with support ears, and the support ears are fixedly connected with the movable clamping plate. Nuts are provided on both sides of the lifting plate along the length direction of the screw rod, and the nuts are threadedly connected to the screw rod.

[0010] Further, a circular groove is formed by recessing the middle position of the surface of the movable clamping plate facing the hydraulic cylinder, and the movable end of the hydraulic cylinder is installed in the circular groove.

[0011] Further, the plug-in block and the end plate are of an integrally formed structure, and adjacent two end plates are in contact with each other.

[0012] Advantages of the present utility model:

[0013] 1. A plurality of equally spaced plug-in grooves are provided on the upper surface of the fixed clamping plate close to the movable clamping plate and on the upper surface of the movable clamping plate close to the fixed clamping plate, and plug-in blocks with end plates are inserted into the plug-in grooves to realize the plug-in connection between the end plates and the fixed clamping plate and the movable clamping plate. Under the protection of the end plates, the fixed clamping plate and the movable clamping plate do not directly contact the surface of the steel rail. When a certain end plate is worn, only the corresponding end plate needs to be replaced, without replacing the entire fixed clamping plate or movable clamping plate, realizing the local replacement of the easily worn parts and reducing the replacement cost.

[0014] 2. The lifting plate installed on the movable clamping plate is in sliding contact with the base. When the hydraulic cylinder drives the movable clamping plate to move, the movable clamping plate drives the lifting plate to slide along the base. At this time, the lifting plate realizes the support for the movable clamping plate, improves the stability of the structure, and at the same time avoids the weight of the movable clamping plate acting completely on the movable end of the hydraulic cylinder, playing a role in protecting the hydraulic cylinder.

[0015] 3. Adjust the position of the lifting plate along the screw rod to make the lifting plate contact different areas of the base, and then use two nuts to limit the relative position between the screw rod and the lifting plate, realizing the adjustment of the relative position between the lifting plate and the base according to needs, and avoiding the lifting plate always contacting a certain area of the base.

[0027] Refer to Figures 1 - 3, on the upper side of the base 1, there is a movable clamping plate 6 for clamping the rail, which is matched with the fixed clamping plate 3. The movable clamping plate 6 is fixedly connected to the movable end of the hydraulic cylinder 8. On one side of the upper surface of the base 1 away from the fixed clamping plate 3, a vertical plate 7 is installed. A through hole is formed on one side surface of the vertical plate 7. The movable end of the hydraulic cylinder 8 penetrates through the through hole, and the cylinder body end of the hydraulic cylinder 8 is fixedly connected to the vertical plate 7 through a plurality of screws. The vertical plate 7 plays a role in supporting the hydraulic cylinder 8. In the middle position of the surface of the movable clamping plate 6 facing the hydraulic cylinder 8, a circular groove 13 is recessed, so that the movable end of the hydraulic cylinder 8 is installed in the circular groove 13, improving the connection stability between the hydraulic cylinder 8 and the movable clamping plate 6.

[0028] Refer to Figures 1 - 5 , on the side of the upper surface of the fixed clamping plate 3 close to the movable clamping plate 6 and on the side of the upper surface of the movable clamping plate 6 close to the fixed clamping plate 3, a plurality of equally spaced plug-in grooves 11 are formed. The bottom of the plug-in groove 11 is closed. A plug-in block 4 is inserted into the plug-in groove 11. One end of the plug-in block 4 outside the plug-in groove 11 is provided with an end plate 5.

The cross-section of the plug-in block 4 is T-shaped, and the cross-section of the plug-in groove 11 is T-shaped. By forming a plurality of equally spaced plug-in grooves 11 on the side of the upper surface of the fixed clamping plate 3 close to the movable clamping plate 6 and on the side of the upper surface of the movable clamping plate 6 close to the fixed clamping plate 3, and inserting the plug-in block 4 with the end plate 5 into the plug-in groove 11, the plug-in of the end plate 5 with the fixed clamping plate 3 and the movable clamping plate 6 is realized.
