Description

Technical Field

[0001] The invention belongs to the field of track processing equipment, and in particular relates to a track bolt extrusion device. Background Art

[0002] When the railway rails are butt-jointed, in order to ensure the rail butt-jointing requirements, plywood is used at the waist of both sides of the joint. In order to meet the insulation performance requirements, glued insulating plywood is used. According to the "Technical Conditions for Glued Insulated Joints of Railway Rails" TB / T2975-2010, the glued insulating plywood is bonded to the rail with adhesive at the construction site and fastened with high-strength bolts. Because the adhesive is very strong, it is very difficult to remove.

[0003] During the operation of the train, the insulating splint bears various loads borne by the rails, so the splint is prone to insulation failure or cracks at the rail joints. The splint is more likely to be damaged at turnouts and curved sections because the rails bear large lateral forces. When the insulating splint is damaged, it must be replaced immediately.

[0004] When disassembling the splint, the high-strength fastening bolts are firmly glued, so the traditional replacement method is to use oxygen, acetylene flame heating or special heating equipment to heat the bolts, and then use a steel chisel or a sledgehammer to smash them. The replacement time is long, the labor intensity is high, and the risk of fire on site is high, and the heating temperature is difficult to effectively control. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a non-heating rail bolt extrusion device that can quickly remove the fixing bolts on the rail insulation clamp.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a rail bolt extrusion device, comprising a bracket, a telescopic member and a push rod, the bracket being an N-shaped bracket penetrating from front to back, the push rod penetrating one side of the bracket in the left-right direction and in sliding contact with the bracket, the bracket having a side on which the push rod is provided and a mounting seat, the mounting seat being used to install or place the telescopic member, the bracket being used to be placed on a rail, and its two sides being respectively located on two sides of the rail, one end of the push rod being located in the bracket being aligned with the threaded end of the bolt to be ejected, the side of the bracket away from the push rod being abutted against the same side of the rail or the insulating splint on the same side, and the telescopic member being used to push the push rod to move to eject the bolt to be ejected from the rail.

[0007] The beneficial effect of the above technical solution is that the telescopic part can be used to push the ejection rod to eject the bolt to be ejected (fixing bolt), wherein the telescopic part can be installed on the mounting seat so that the entire device is a whole. Of course, the telescopic part can also be placed on the mounting seat. When working, the telescopic part uses the mounting seat as a support to increase the thrust, so that the entire device can be temporarily assembled when in use, and the assembly is extremely convenient.

[0016] The bracket in the above technical solution includes a first connecting rod, a second connecting rod and two n-shaped parts, the two n-shaped parts are arranged in the left-right direction and spaced apart in the front-back direction, the first connecting rod is horizontally arranged in the middle of the upper ends of the two n-shaped parts in the front-back direction, and its two ends are respectively connected and fixed to the upper ends of the two n-shaped parts, the second connecting rod is horizontally arranged between the two n-shaped parts in the front-back direction, and its two ends are connected to the same side of the two n-shaped parts, the push rod is placed between the two n-shaped parts in the left-right direction, and passes through the middle part corresponding to the length direction of the second connecting rod and is in sliding contact with it, the two sides of the notch of the U-shaped part are respectively connected and fixed to one side of the upper ends of the two n-shaped parts close to the second connecting rod, the two n-shaped parts are used to be placed above the rail, and the rail passes through the grooves of the two n-shaped parts, and the sides of the two n-shaped parts away from the push rod are both against the same side of the rail or the insulating splint on the same side.

[0017] The beneficial effect of the above technical solution is that it has a simple structure and can leave a middle portion of the side of the bracket away from the ejection rod vacant to avoid blocking the ejection of the ejection bolt.

[0018] The bracket in the above technical solution also includes a top adjusting bolt. A first screw hole is provided in the middle of the upper end of the first connecting rod, which passes through it from top to bottom and is threadedly matched with the top adjusting bolt. The threaded end of the top adjusting bolt passes through the first screw hole from top to bottom and is threadedly connected with it. Under the action of external force, the top adjusting bolt is rotated until its threaded end contacts the upper end of the rail head to adjust the spacing distance between the first connecting rod and the rail head.

[0019] The beneficial effect of the above technical solution is that the depth of the rail head extending into the bracket can be adjusted by the top adjustment bolt so as to adjust the alignment of the push rod and the bolt to be ejected.

[0020] In the above technical solution, the second connecting rod is slidably connected to the same side of the two n-shaped members, and can slide up and down along the same side of the two n-shaped members under the action of external force to adjust the horizontal height of the push rod.
