Description

Technical Field

[0001] The utility model relates to the technical field of rails, in particular to a device for removing a splint from a bonded joint. Background Art

[0002] At present, railway track circuits are the main means of identifying the direction of train operation, and glued insulating joints in track circuits are common equipment on railway lines. Glued insulating joints are the main method of blocking the conduction of rail current by physical means. Glued insulating joints are mainly composed of insulating splints, insulating rail ends, insulating bolt sleeves, and bolts. The rails, insulating splints, insulating rail ends, and insulating bolt sleeves are bonded together by strong glue, and finally the above structure is tightened by high-strength torque bolts, and the bolt torque reaches 1100~1400n·m.

[0003] When the insulating function of the insulating joint fails or the rail or the plywood is damaged and needs to be replaced or repaired, the plywood on both sides of the rail glued insulating joint needs to be removed. In the prior art, the plywood is usually removed by hitting the plywood with a sledgehammer, baking the vulcanized adhesive layer with fire, or scraping along the rail direction, which can easily damage the rail and the plywood. In addition, the baking method is not only very time-consuming, but also has major safety hazards. The scraping method along the rail direction has high requirements for the cutter, requires great force, and the cutter is easy to wear and has high replacement and maintenance costs. In addition, the rail waist is curved, and the cutter cannot completely imitate the rail waist profile, which can easily damage the rail waist.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a device for removing the splint of the bonded joint. Utility Model Content

[0029] The bracket assembly 1 includes a frame 11, an elastic auxiliary clamping assembly 12, support feet 13, and a handle 14. A clamping groove 10 capable of being clamped onto the rail is provided at the lower end of the frame 11. The elastic auxiliary clamping assemblies 12 are installed on the frame 11 on both sides of the clamping groove 10. The two elastic auxiliary clamping assemblies 12 respectively point in opposite directions to the two rails at the docking location. Support feet 13 capable of adjusting the installation height are installed around the frame 11. By adjusting the four support feet, the entire frame 11 can be more firmly in the working position, making the entire demolition device more stable during operation. Handles 14 for easy handling are also installed on both sides of the frame 11. During use, the entire demolition device is carried and placed on the rail through the handles 14 on both sides of the frame 11.

[0030] The elastic auxiliary clamping assembly 12 includes a sleeve 121, a lead screw nut 122, a clamping top block 123, a buffer spring 124, and an adjustment knob 125. The sleeve 121 is horizontally installed on the frame 11. The sleeve 121 is internally provided with a lead screw nut 122 and a clamping top block 123. The clamping top block 123 points to the rail. The lead screw nut 122 and the clamping top block 123 are elastically connected through the buffer spring 124. The lead screw nut 122 is threadedly connected to the adjustment knob 125. The adjustment knob 125 is movably clamped on the frame 11. By rotating the adjustment knob 125, the rotation of the adjustment knob 125 drives the horizontal movement of the lead screw nut 122, and the lead screw nut 122 pushes the clamping top block 123 onto the rail.

[0031] The lifting wheel assembly 2 includes a bracket 21, a rotating frame 22, a lifting wheel 23, a limiting block 24, a lifting screw 25, and a limiting rod 26. The bracket 21 is fixed to the frame 11. The rotating frame 22 is rotatably installed on the bracket 21. The extending end of the rotating frame 22 is inserted with the lifting wheel 23. The limiting block 24 is inserted in the middle of the rotating frame 22. The lifting screw 25 is threadedly connected to the bracket 21 above the limiting block 24. The lifting screw 25 is inserted into the limiting block 24. An annular limiting groove 250 is provided at the lower end of the lifting screw 25.

The two oil cylinders 31 are installed on both sides of the frame 11 and are respectively opposite to two rails at the docking place. The oil cylinder 31 drives the top block 32 to move towards the rail direction. An electric oil pump 33 is installed at the side end of the frame 11. The electric oil pump 33 is connected to the reversing valve 34 through a pipeline. The reversing valve 34 is connected to the two oil cylinders 31 through a pipeline. A control button 331 is arranged on the electric oil pump 33. An oil filling port 332 and an oil level observation window 333 are also opened on the electric oil pump 33, which is convenient for judging the amount of oil and filling hydraulic oil to ensure the normal operation of the demolition device. A pressure gauge 35 and a pressure valve 36 are installed at the oil outlet of the electric oil pump 33. During the working process, the working state can be judged by observing the pressure value. At the same time, the whole hydraulic system has a pressure protection setting. After reaching a certain pressure, to protect the safety of the equipment and components, the hydraulic system will automatically relieve pressure through the pressure valve 36. The electric oil pump 33 is externally connected to a power supply, and the power supply includes a lithium battery or a generator.

[0033] When the bonded joint splint demolition device of the present utility model is working, the whole demolition device is carried and placed on the rail through the handles 14 on both sides of the frame 11. Adjust the lifting screws 25 of the front and rear lifting wheel assemblies 2. Rotate the lifting screws 25 to drive the lifting wheels 23 to move downward. The lifting wheels 23 roll and contact the top surface of the rail, lifting the frame 11 so that its whole body does not contact the top surface of the rail. Then slowly push it to the position of the bonded joint splint to be disassembled, so that the joint is located in the middle of the two oil cylinders 31. Lower the lifting wheel assembly 2 so that the main body of the frame 11 contacts the top surface of the rail. Then rotate the adjustment knob 125 to make the clamping top blocks 123 of the elastic auxiliary clamping assemblies 12 at both ends press against the rail. In order to make the whole demolition device more stable during work, adjust the four support feet 13 to make the whole more firmly in the working position. Then after connecting the power supply (lithium battery or generator), press the start button 331. At this time, the oil cylinder 31 slowly extends, and then the top block 32 at the front end of the oil cylinder 31 contacts the side surface of the rail head. The two oil cylinders 31 are respectively pressed on different rails and move in opposite directions until the splints at both ends are separated from the rail. Then press the stop button 331, rotate the reversing valve 34, and then press the start button 331. The oil cylinder 31 retracts to the original position. Loosen the elastic auxiliary clamping assembly 12, retract the support feet 13, adjust the lifting wheel assembly 2, and finally push the whole demolition device away from the demolition position to perform the next operation of replacing the splint.
