Description

Technical Field

[0001] The utility model mainly relates to the technical field of railway rails, in particular to a rapid dismantling device for railway glued insulating splints. Background Art

[0002] Glued insulation joints are an important component of railway tracks. They are mainly used in the insulation joints of insulated track circuits and seamless line switches on seamless lines. When a glued insulation joint leaks, it needs to be promptly removed and re-glued. The replacement process includes removing the old insulating plywood, grinding the bonding surfaces on both sides of the rail, and re-gluing the insulation. The railway can only be opened to traffic after the insulation is tested to be in good condition. Glued insulation is to completely glue the plywood together with epoxy resin glue. Because epoxy resin glue has very strong adhesion, there is no gap between the plywood and the rail, and there is no leverage point. Once a leak occurs, it is difficult to disassemble. The current common removal method is to bake the plywood with gas, oxygen, or acetylene, and hammer the plywood to separate the plywood. The plywood is then propped open with an inclined iron for replacement. This is time-consuming and may result in the work of re-gluing the insulating plywood not being completed within the railway skylight point or the emergency red light zone time, resulting in a general Class D accident, which has a significant impact on railway transportation and disrupts the operation of railway trains.

[0003] Some of the existing mechanical dismantling devices in China use incorrect force methods, require very large forces, are bulky and complicated to assemble; some require electric welding. Due to the rigor of railway safety, it is impossible to ensure that every work area has a welder's license on duty during emergency response. Therefore, the utility model provides a railway glued insulating splint rapid dismantling device. Summary of the Invention

[0004] In order to address the deficiencies of the prior art, the utility model provides a device for quickly dismantling railway glued insulating splints. Specifically, when insulation leakage occurs in railway glued insulating joints, the device can dismantle the glued insulating splints in a short time, thereby saving operation time and restoring train operation order as soon as possible.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] A rapid dismantling device for railway adhesively bonded insulating splints comprises a tapping device and a hydraulic cylinder device.

[0007] The tapping device includes a fixed box and an L-shaped base plate, the L-shaped base plate is fixedly connected to the bottom of the fixed box, a screw constraint seat is provided inside the right side of the fixed box, the middle part of the screw constraint seat is connected to the screw device through a thread, the screw device includes a screw, a rotating disk and a fixed disk, the fixed disk is connected to the rear end of the fixed speed motor, the front end of the fixed speed motor is connected to the tap through a rotating shaft, and the tap passes through a circular hole provided on the left side of the fixed box.

[0021] like Figure 1-3 As shown, a rapid dismantling device for railway adhesive-bonded insulating splints includes a tapping device 1 and a hydraulic cylinder device 2.

[0022] The tapping device 1 includes a fixed box 3 and an L-shaped base plate 4, the L-shaped base plate 4 is fixedly connected to the bottom of the fixed box 3, a screw constraint seat 5 is provided inside the right side of the fixed box 3, the middle part of the screw constraint seat 5 is connected to the screw device 6 through a thread, the screw device 6 includes a screw 61, a rotating disk 62 and a fixed disk 63, the fixed disk 63 is connected to the rear end of the constant speed motor 7, the front end of the constant speed motor 7 is connected to the tap 9 through the rotating shaft 8, and the tap 9 passes through the circular hole 10 provided on the left side of the fixed box 3.

[0023] Specifically, the constant speed motor is arranged inside the fixed box, and the screw device is connected to the rear end of the constant speed motor. The position of the constant speed motor can be adjusted by adjusting the screw device, and the position of the constant speed motor can be pushed and pulled by the rotating disk to adjust it to a suitable tapping position.

[0024] The hydraulic cylinder device 2 includes a separate hydraulic jack 21, a separate oil pump 22 and a high-pressure oil pipe 23. The separate hydraulic jack 21 and the separate oil pump 22 are connected by the high-pressure oil pipe 23. The separate hydraulic jack 21 is fixedly arranged on the bottom side of the fixed frame 11. A nut 12 is fixedly arranged at the bottom of the fixed frame 11. A long nut 13 is provided on the upper part of the fixed frame 11 and passes through the upper fixing plate 14 to be detachably connected to the nut 12 by a thread.

[0025] Specifically, the hydraulic cylinder device adopts a separate hydraulic device in the prior art, wherein the hydraulic rod of the separate hydraulic jack is extended by pressing the handle of the separate oil pump, thereby facilitating the removal of the rail splint.

[0026] Furthermore, a rotating bolt 15 is provided on the L-shaped bottom plate 4, which can be rotated to adjust the position to fix the clamping plate on the other side.

[0027] Furthermore, the separate hydraulic jack 21 is a split jack device with a tonnage of 50 tons and a stroke of 50 mm.

[0028] Furthermore, a wire connection hole 16 and a motor forward and reverse switch 17 are provided on the upper side of the fixing box 3 .

[0029] Specific working principle:

[0030] The tapping device uses a fixed-speed motor to tap, removing the six bolts that typically secure the rail cleat. The hydraulic cylinder extends a hydraulic rod with a powerful thrust, sufficient to loosen the rail cleat and accelerate its removal.

[0031] When tapping, pass the L-shaped plate from the bottom of the track to the other side, clamp the bottom of the track, rotate the bolt on the other side to support the splint, connect the wires through the wire connection hole, and control the fixed speed motor through the motor forward and reverse switch to drive the tap to rotate and tap.

[0032] The motor switch is turned to forward to drive the tap to tap. After the tapping is completed, the motor switch is turned to reverse.

[0033] Unscrew the tap and screw the special bolt into the tapped plywood screw hole to serve as an anchor. When disassembling the plywood, insert a removed old bolt from the opposite screw hole into the screw hole with the anchor bolt. Hold the anchor bolt against the bolt and use the bolt anchored in the bolt hole on one side of the plywood as a leverage point. Adjust the hydraulic jack of the hydraulic cylinder device to the relative position of this specific bolt hole. The lower end of the fixed frame passes through the sleeper from the bottom of the rail and is fixed to the upper fixing plate and nut through a long nut. Then, by pressing the handle of the separation oil pump, the hydraulic rod of the separation hydraulic jack is extended, transmitting force to the bolt on the bolt hole, and pushing open the plywood with the bolt.
