Description

Technical Field

[0001] The present application relates to the field of rail maintenance devices, and in particular to a combined cutter device of a hydraulically bonded insulating splint disassembly device. Background Art

[0002] In order to improve the insulation of train rails, it is necessary to install insulating splints on both sides of the rail waist. The insulating splints are connected to the rails by gluing. When the insulating splints are used for a long time, they are prone to damage, which reduces the insulation performance. Maintenance personnel are required to remove the insulating splints and replace them with new ones.

[0003] The removal of the insulating splint is usually done manually. The maintenance personnel use a cutter to remove it. The cutter is inserted between the insulating splint and the rail so that the cutter can cut the adhesive layer between the insulating splint and the rail, thereby achieving the effect of removing the insulating splint.

[0004] The above-mentioned related technical solutions have the following defects: due to the close fit between the insulating clamp and the rail, it is time-consuming and laborious to manually insert the cutter between the insulating clamp and the rail, and the removal work efficiency is low. Utility Model Content

[0005] In order to improve the efficiency of removing insulating splints, the present application provides a combined cutting knife device of a hydraulically bonded insulating splint removal device.

[0006] The combined cutter device of the hydraulically bonded insulating splint disassembly device provided in the present application adopts the following technical solution:

[0007] A combined cutter device of a hydraulically bonded insulating splint disassembly device comprises a frame, a movable cutter and a fixed cutter, the frame comprises two end plates and a plurality of connecting rods, the end plates are arranged parallel to each other, the connecting rods are parallel to each other, one end of the connecting rod is fixedly connected to one end plate, the movable cutter and the fixed cutter are respectively mounted on the two end plates, the movable cutter and the fixed cutter are arranged facing each other, the movable cutter comprises an oil cylinder and a movable cutter head, the cylinder body of the oil cylinder is fixed on the end plates, the piston rod of the oil cylinder is connected to the movable cutter head, and the oil cylinder is used to drive the movable cutter head to move back and forth.

[0008] By adopting the above technical solution, by arranging the movable cutter and the fixed cutter on the frame, when the user sets the frame on the rail, the fixed cutter and the movable cutter can be respectively located on both sides of the insulating splint in the horizontal direction, and the user controls the extension of the oil cylinder so that the movable cutter head can move horizontally and abut against the adhesive layer between the insulating splint and the rail, and by continuously extending the oil cylinder, the movable cutter head and the fixed cutter can clamp the adhesive layer, and then the movable cutter head can be inserted between the insulating splint and the rail, so as to achieve the effect of destroying the adhesive layer and removing the insulating splint, and during the extension of the oil cylinder, the frame is clamped and fixed on the rail by the movable cutter and the fixed cutter, so that the oil cylinder can stably extend and advance.

[0009] Optionally, a connecting seat is connected to the piston rod of the oil cylinder, and the connecting seat is connected to the movable cutter head.

[0012] By adopting the above technical solution, by providing an arc surface on the movable cutter head, when the oil cylinder is extended, the arc surface of the movable cutter head abuts against the adhesive layer between the insulating splint and the rail, thereby reducing the contact area between the movable cutter head and the adhesive layer, causing the adhesive layer to be subjected to greater stress, thereby improving the effect of the movable cutter head in destroying the adhesive layer.

[0014] By adopting the above technical solution, a fixed blade head is arranged on the mounting seat so that the abutting surface of the fixed blade head abuts against the surface of the end plate. When the oil cylinder is extended, the end plate applies a supporting force to the fixed blade head, thereby enabling the fixed blade head to apply a larger stress to the adhesive layer, so that both sides of the insulating splint are subjected to force, thereby improving the efficiency of removing the insulating splint.

The user controls the extension of the oil cylinder to enable the movable cutter head to move horizontally and abut against the adhesive layer between the insulating clamping plate and the rail. By continuously extending the oil cylinder, the movable cutter head and the fixed cutter can clamp the adhesive layer, and then the movable cutter head can be inserted between the insulating clamping plate and the rail, so as to achieve the effect of destroying the adhesive layer and removing the insulating clamping plate. During the extension of the oil cylinder, the frame is clamped and fixed on the rail by the movable cutter and the fixed cutter, so that the oil cylinder can be stably extended and the cutter can be advanced;

[0025] 2. By providing an arc surface on the movable cutter head, when the oil cylinder is extended, the arc surface of the movable cutter head abuts against the adhesive layer between the insulating clamping plate and the rail, thereby reducing the contact area between the movable cutter head and the adhesive layer, causing greater stress on the adhesive layer, which can improve the effect of the movable cutter head in destroying the adhesive layer;

[0026] 3. By setting a magnet on the fixed cutter head, the magnet can be adsorbed on the surface of the rail waist. When the oil cylinder drives the movable cutter head to advance, the fixed cutter head can fit on the rail waist, so that the blade of the fixed cutter head can be inserted into the adhesive layer between the rail waist and the insulating splint.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses a combined cutter device of a hydraulically bonded insulating splint disassembly device, referring to Figure 1 , Figure 2 and Figure 3 , including a frame 1, a movable cutter 2 and a fixed cutter 3. The frame 1 includes two end plates 11 and a plurality of connecting rods 12. The connecting rods 12 are parallel to each other. One end of the connecting rod 12 is fixedly connected to one end plate 11. The end plate 11 and the connecting rod 12 are arranged vertically. The movable cutter 2 is installed on one end plate 11, and the fixed cutter 3 is installed on the other end plate 11. The movable cutter 2 and the fixed cutter 3 are arranged opposite to each other. The movable cutter 2 includes an oil cylinder 21, a connecting seat 22 and a movable cutter head 23. The oil cylinder 21 is fixed on the end plate 11. The piston rod of the oil cylinder 21 is connected to the connecting seat 22. The movable cutter head 23 is detachably connected to the connecting seat 22. The length direction of the oil cylinder 21 is parallel to the length direction of the connecting rod 12. The user can control the sliding of the piston rod of the oil cylinder 21 to move the movable cutter head 23 toward the fixed cutter 3. The user sets the frame 1 at the rail on which the insulating splint is installed, so that the movable cutter 2 and the fixed cutter 3 are respectively located on both sides of the insulating splint. The user pushes the movable cutter head 23 by the oil cylinder 21, so that the movable cutter head 23 and the fixed cutter 3 are respectively pressed against both sides of the insulating splint, thereby achieving the purpose of removing the insulating splint.

[0036] Reference Figure 2The end plate 11 is provided with a clearance groove 111, which is used to be clamped on the rail. The user can vertically move the frame 1 so that the frame 1 is covered on the rail and the movable cutter 2 is located at the waist of the rail. The end plate 11 is provided with a handle 13, and the user can lift and move the frame 1 through the handle 13.

[0037] In other embodiments, reference Figure 2 and Figure 3 A block 221 is fixedly connected to one end of the connection seat 22 away from the oil cylinder 21. The block 221 and the moving cutter head 23 are provided with a slide groove 231. The moving cutter head 23 is slidably connected to the connection seat 22 through the slide groove 231. The user can remove the moving cutter head 23 from the connection seat 22 for maintenance and replacement. The moving cutter head 23 is provided with an arc surface 232. When the oil cylinder 21 pushes the moving cutter head 23 to abut against the adhesive layer between the insulating splint and the rail waist, the arc surface 232 abuts against the adhesive layer, thereby reducing the contact area between the moving cutter head 23 and the adhesive layer, making the pressure at the end of the moving cutter head 23 larger, so that the adhesive layer can be subjected to a larger pressure and damaged, thereby improving the efficiency of removing the insulating splint. Two movable cutters 2 are arranged on each end plate 11, and the two movable cutters 2 are respectively arranged on both sides of the clearance groove 111. When the frame 1 is installed on the rail, the two movable cutters 2 are respectively located on both sides of the rail waist, so that the two movable cutters 2 can simultaneously remove the insulating splints on both sides of the rail, thereby improving work efficiency.

[0038] Reference Figure 4 Two fixed cutters 3 are arranged on each end plate 11. The two fixed cutters 3 are arranged on both sides of the clearance groove 111 respectively. The two fixed cutters 3 can respectively press against the two insulating clamping plates on both sides of the rail waist. The fixed cutter 3 includes a mounting seat 31 and a fixed cutter head 32. The mounting seat 31 is fixed on the end plate 11. One mounting seat 31 is installed on one side of the clearance groove 111. The fixed cutter head 32 is detachably connected to the mounting seat 31.

[0039] Reference Figure 5 and Figure 6 The fixed blade head 32 is provided with an abutting surface 324 and a fitting surface 325. The fixed blade head 32 is a right-angled plate. The abutting surface 324 on the fixed blade head 32 is connected to the mounting seat 31 on the surface of the end plate 11, and the fitting surface 325 on the fixed blade head 32 fits with the rail waist. When the movable cutter 2 feeds and removes the insulating splint, the end plate 11 applies a supporting force to the fixed blade head 32 through the abutting surface 324. The blade of the fixed blade head 32 is a thin blade, and the blade surface is flush with the fitting surface 325.

[0040] Reference Figure 4The fixed blade head 32 is slidably connected with the mounting seat 31. The mounting seat 31 is provided with a mounting groove 311, which is horizontally provided. A slide bar 322 is fixedly connected to the fixed blade head 32, and the slide bar 322 is provided on the abutment surface 324. The user can connect the mounting seat 31 with the fixed blade head 32 by sliding the slide bar 322 into the mounting groove 311. The blade body of the fixed blade head 32 can be directly inserted into the slide groove provided on the fixed blade measuring end plate and the swing block. The fixed blade head 32 is provided with a magnetic steel 321, which is provided on the fitting surface 325 of the fixed blade head 32 and embedded in the fixed blade head 32. When the frame 1 is installed on the rail, the magnetic steel 321 is magnetically connected to the rail, so that the blade of the fixed blade head 32 can fit the rail and be inserted between the rail and the insulating clamping plate. When the thickness of the rail changes, the magnetic steel 321 can always fit on the surface of the rail, and the fixed blade head 32 can automatically slide on the mounting seat 31, so that the distance between the two fixed cutters 3 on the end plate 11 is automatically adjusted. The blade of the fixed blade head 32 is provided with an arc surface 323, and the blade abuts against the adhesive layer between the insulating clamping plate and the rail through the arc surface 323.

[0041] The implementation principle of the embodiment of the present application is: by arranging a movable cutter 2 and a fixed cutter 3 on the frame 1, the user can install the frame 1 on the rail so that the movable cutter 2 and the fixed cutter 3 are respectively located on both sides of the insulating splint, and the oil cylinder 21 can drive the movable cutter head 23 to move by extending, so that the movable cutter head 23 and the fixed cutter head 32 are inserted into the adhesive layer between the insulating splint and the rail, thereby achieving the effect of removing the insulating splint.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
