Description

Technical Field

[0001] This utility model relates to the field of railway maintenance equipment technology, and in particular to a glued insulated joint cutting frame. Background Technology

[0002] The section of a railway line where rails are connected by bolts and clamps is called a rail joint. Due to repeated impacts from train wheels, the rail head at these joints is prone to deformation, resulting in thickened edges. For ordinary rail joints, this thickening increases rail vibration when trains pass, gradually expanding the damaged area and depth, eventually rendering the rail unusable and significantly increasing the workload of joint maintenance. For insulated, glued rail joints, the thickening can narrow the rail gap or cause short circuits, turning the train signal from green to red and resulting in a train stop. Therefore, track maintenance departments consider repairing thickened rail joints a key aspect of track maintenance.

[0003] In the existing technology, patents such as CN220888170U rail end cutting and grinding machine support and CN205856947U rail joint rail end burr cutting machine provide solutions for cutting thick edges using an angle grinder. However, these solutions have drawbacks such as inconvenient operation, complex structure, and difficulty in controlling the cutting depth of the angle grinder. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a glued insulation joint cutting frame. Its scientific structure allows it to cut burrs and other defects on the ends of rails, keeping the cut surface stable and preventing wobbling. This improves the surface quality of the cut surface, makes it safe and reliable, easy to use, and reduces labor intensity.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0023] like Figure 1 , Figure 2 As shown, the adhesive insulation joint cutting frame of this embodiment includes a fixed base 1, a hinged base 2 on the upper part of the fixed base 1, a slide rail 3 for vertically passing above the steel rail on the hinged base 2, the slide rail 3 being hinged to the hinged base 2 via a hinge shaft, and a limiting screw 4 for limiting the rotation angle of the slide rail 3 on the hinged base 2. A slider 5 is slidably connected to the slide rail 3, and an angle grinder mounting frame 6 is fixedly connected to the slider 5. In use, the device is fixed to the rail head of the steel rail to be cut via the fixed base 1, and the angle grinder is fixedly placed on the angle grinder mounting frame 6. This allows the angle grinder to slide back and forth along the slide rail 3 above the steel rail in a direction perpendicular to the steel rail. The grinding wheel of the angle grinder is located in a vertical plane. Because the slide rail 3 is perpendicular to the steel rail, it ensures that the grinding wheel of the angle grinder is in the same vertical plane during cutting without shifting, thereby improving the cutting quality. More importantly, the angle grinder can not only move left and right along the slide rail, but also the downward movement distance of the angle grinder is limited by the limiting screw 4, but its upward movement is not limited. This allows the cutting depth to be limited first during cutting, and the slide rail can be rotated upward after cutting to remove the angle grinder from the cutting surface.

[0024] The device has a simple structure, is easy to use, can control the cutting depth, is easy to exit, is safe and reliable, and improves the surface quality of the cut surface.

[0025] Furthermore, the fixing base 1 includes a first side plate 11, a second side plate 12, and a connecting plate 13 connecting the first side plate 11 and the second side plate 12. The fixing base 1 is generally U-shaped with the opening facing downwards. In use, it is fastened onto the rail. The first side plate 11 abuts against the rail head side of the rail, and the connecting plate 13 abuts against the upper surface of the rail head. The second side plate 12 is provided with a clamping screw 14, which is threadedly connected to the second side plate 12 in a horizontal direction. In use, tightening the clamping screw 14 presses the rail against the first side plate 11 from the side, thereby fixing the device onto the rail.

[0026] like Figure 1 As shown, the slide rail 3 is located on both sides of the hinge shaft, with a long end and a short end respectively. The end of the limiting screw 4 abuts against the short end from above, preventing the angle grinder from swinging downwards with the slide rail 3 during cutting. When a deeper cut is needed, the angle of the slide rail 3 can be adjusted by turning the limiting screw 4. The slider 5 slides freely along the long end, that is, it slides left and right along the slide rail 3 for cutting.

[0027] Furthermore, the limiting screw 4 is threadedly connected to the hinge seat 2.

[0028] like Figure 2 As shown, the long end is connected to the upper end of the tension spring 7, and the lower end of the tension spring 7 is connected to the fixed base 1. The tension spring 7 gives the slide rail 3 a downward swinging force, so that the short end of the slide rail 3 abuts the end of the limiting screw 4 upward, so that the slide rail 3 can automatically return to its original position after swinging upward.

[0029] Furthermore, a limiting plate 8 is provided at the end of the long end, and the limiting plate is connected to the tension spring 7. The limiting plate 8 can prevent the slider 5 from disengaging from the slide rail 3.

[0030] Furthermore, the angle grinder mounting bracket 6 is provided with a support plate that matches the contour of the angle grinder. The support plate is provided with fixing holes for fixing the angle grinder. The angle grinder is not shown in the figure. The angle grinder is an electric angle grinder. When placed, the handle is facing upward and the grinding wheel is facing downward. When in use, the construction worker holds the handle and pushes the angle grinder to slide along the slide rail 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
