[0002] With the rapid development of the national economy, railway tracks have become an indispensable mode of transportation in people's economic lives, bringing great convenience to people's travel and economic life. Adhesive-bonded insulated joints are key components used in railway track construction to connect rails and achieve electrical insulation. They use special adhesives and insulating materials (such as high-strength insulating cloth, synthetic putty, etc.) to firmly bond the joint clamps to the rails, forming a high-strength connection with excellent insulation performance.

[0003] Over prolonged use, and with changes in various climates, the joint clamps of bonded insulated joints may break, pull apart, or experience insulation failure. In such cases, the bonded insulated joint needs to be disassembled and replaced. The traditional method for disassembling bonded insulated joints involves heating the joint with a fire and then manually hammering it apart.

[0004] However, the fire-heating operation poses safety hazards, and the process of dismantling by fire and hammering not only easily damages the rails, but also involves complex, time-consuming, and labor-intensive operations with low dismantling efficiency, resulting in poor safety and work efficiency.

[0039] In existing rail bonded insulated joint removal operations, the adhesive is typically softened by heating with a fire, and then hammered with tools such as hammers to dismantle the joint clamps. However, heating the joint clamps with a fire poses a risk of burns to personnel, especially in winter operations, where uneven heating can damage the rails. Furthermore, hammering after heating can also easily damage the rails, and the process is inefficient. Performing dismantling operations during maintenance windows can also disrupt the normal operation of the entire railway section.

[0040] See Figures 1 to 4 The diagram shows a schematic of a bonding insulation joint removal device provided by the present invention, including: a working head 1, a mounting component 2, a telescopic component 3, and a base 4; the mounting component 2 has a groove 21 extending along the extension direction of the rail 5 on its lower side, the groove 21 being used to accommodate the rail 5; the mounting component 2 includes a removal side 22 and a driving side 23 that are opposite to each other in the extension direction of the rail 5; one end of the telescopic component 3 is fixedly connected to the driving side 23, and the other end is fixedly mounted on the base 4; the working head 1 is detachably mounted on the removal side 22, and when the working head 1 is mounted on the removal side 22, the working head 1 fits against the web of the rail 5.

[0041] In this embodiment, the mounting component 2 is installed on the rail 5 using the groove 21 on its lower side. When the working head 1 is installed on the removal side 22, it fits against the rail web of the rail 5. When it is necessary to remove the bonded insulation joint, the base 4 and the telescopic component 3 are used to move the working head 1 on the removal side 22, which is attached to the rail web, towards the bonding point between the joint clamp and the rail web of the bonded insulation joint, thereby removing the joint clamp from the rail web and achieving rapid and efficient removal. The bonded insulation joint removal device provided in this utility model solves the technical problems of complex, time-consuming, labor-intensive, and unsafe operation in the traditional process of removing bonded insulation joints by heating the bonded insulation joint with fire and then manually hammering it.

[0042] Furthermore, the working head in this utility model can be made of alloy steel and can be detachably connected to the dismantling side 22 by bolts or buckles. Its working surface matches the rail web of the rail 5 to ensure a close fit. The mounting part 2 can be a U-shaped steel frame with a groove 21 on the lower side that extends along the direction of the rail 5. The main body of the telescopic part 3 can be fixedly installed on the base 4 by bolts or welding, and the extended part can be fixedly installed on the driving side 23 by welding, hinge, or bolts. The base 4 can be made of steel plate by welding, and its bottom can also be provided with anti-slip blocks to protect the rail 5 and maintain a stable position during the extension of the telescopic part 3.

[0043] For example, when it is necessary to disassemble the bonded insulation joint, first remove the fixing bolts on the bonded insulation joint, and then install the bonded insulation joint disassembly device of this utility model: place the base 4 on the rail 5, so that the groove 21 on the lower side of the mounting part 2 accommodates the rail 5, and install the working head 1 on the disassembly side 22, so that the working head 1 fits against the rail web of the rail 5 and is close to the bonding point between the joint clamp plate on the bonded insulation joint and the rail web. The telescopic part 3 drives the working head 1 to move towards the bonding point, so that the working head 1 quickly removes the joint clamp plate on the bonded insulation joint from the bonding point of the rail web. After the disassembly is completed, remove the working head and reset the telescopic part 3 to complete the disassembly operation.

[0044] Furthermore, on the side of the base 4 opposite to the telescopic member 3, a gripping member 6 is also provided to facilitate the gripping and operation of the staff during use.

[0045] Optionally, refer to Figure 2 In this utility model, there are two working heads 1. When the two working heads 1 are installed on the removal side 22, the two working heads 1 are symmetrically attached to both sides of the rail web of the rail 5.

[0046] In this embodiment, two sets of installation interfaces (such as dovetail grooves or threaded holes) can be symmetrically set on the removal side 22 of the mounting component 2. The two working heads 1 can be symmetrically fixed by bolts, and their inner working surfaces are in contact with both sides of the rail web. During use, the adhesive insulation joints can be removed on both sides of the rail 5, thereby improving work efficiency.

[0047] Optionally, refer to Figure 1 and Figure 2 In this utility model, the working head 1 is a wedge-shaped block; the adhesive insulation joint removal device also includes a clamp 7, which is detachably installed on the removal side 22; the wedge-shaped block is fixedly installed on the side of the clamp 7 away from the mounting part 2; the clamp 7 is provided with a limiting groove 71, which fits against the rail head of the rail 5; when the clamps 7 of the two working heads 1 are installed on the removal side 22, the two clamps 7 use the limiting groove 71 to clamp the rail head of the rail 5, and make the wedge-shaped block fit against the rail web of the rail 5.

[0048] In this embodiment, two clamps 7 are used to position the rail 5 and to make the wedge block fit against the rail web. This ensures the stability of the wedge block and improves dismantling efficiency as the telescopic component 3 moves the mounting component 2. In use, the limiting grooves 71 of the two clamps 7 are inserted into the rail head, and the clamps 7 are positioned by their own weight. Then, the clamps 7 are installed on the dismantling side 22 using bolts or other fasteners. After the telescopic component 3 is activated, the mounting component 2 and the clamps 7 move the wedge block along the rail web, generating continuous shearing force and gradually peeling off the adhesive layer.

[0049] Furthermore, the fixture 7 is a split cast steel part with a limiting groove 71 machined on the inner side. The depth of the limiting groove 71 is greater than the height of the rail head, and the width of the groove matches the rail head.

[0050] Furthermore, the working angle of the wedge block is 30 to 45 degrees.

[0051] Optionally, the limiting groove 71 in this utility model is provided with a ball bearing.

[0052] In this embodiment, a ball bearing is provided in the limiting groove 71. When using this device for dismantling operations, the sliding friction is converted into rolling friction, which avoids jamming and reduces the risk of the limiting groove 71 scratching the rail 5.

[0053] Optionally, the telescopic component 3 in this utility model includes two hydraulic cylinders 31, one end of each hydraulic cylinder 31 is connected to the drive side 23, and the other end is fixedly mounted on the base 4.

[0054] In this embodiment, two hydraulic cylinders 31 are arranged in parallel. Their cylinder bodies can be fixed to the base 4 by flanges. The end of the piston rod can be connected to the drive side 23 by ball joint to allow for slight deflection. During use, the two hydraulic cylinders 31 are driven synchronously to push the mounting part 2 to drive the working head 1 to move and dismantle.

[0055] Furthermore, in this embodiment, the maximum thrust of the hydraulic cylinder 31 is 30 MPa.

[0056] Optionally, refer to Figure 2 In this utility model, a rocker arm 41 is movably mounted on the base 4. The rocker arm 41 is connected to two hydraulic cylinders 31 and is used to control the hydraulic cylinders 31.

[0057] In this embodiment, a rocker arm 41 is provided on the base 4 to control the hydraulic cylinder 31. Specifically, the rocker arm 41 is a T-shaped manual lever that is linked to the hydraulic directional valve through a gear and rack mechanism. The stroke of the hydraulic cylinder 31 is adjusted by swinging the rocker arm. Specifically, the gear is fixed to the rocker arm 41 by a key connection, and the rack is connected to the valve core of the hydraulic directional valve by a thread. The hydraulic directional valve is connected to the oil circuit of the hydraulic cylinder. The swing of the rocker arm 41 is converted into the linear motion of the rack through the gear and rack mechanism, thereby driving the valve core of the hydraulic directional valve to move and realizing the adjustment of the stroke of the hydraulic cylinder 31.

[0058] Optionally, refer to Figure 2 The telescopic component 3 in this utility model also includes an elastic reset component 32; the two ends of the elastic reset component 32 are respectively connected to the base 4 and the driving side 23.

[0059] In this embodiment, after the dismantling operation is completed, the hydraulic cylinder 31 is depressurized, and the elastic reset member 32 automatically pulls the installation part 2 back to its initial position, reducing the manual reset operation time and improving the work efficiency.

[0060] Furthermore, the elastic reset component 32 can be made up of two sets of disc springs, symmetrically arranged on both sides of the hydraulic cylinder, with a preload of 10% of the maximum thrust of the hydraulic cylinder; the two ends of the springs can be connected to the base 4 and the drive side 23 of the mounting component respectively through hooks.

[0061] Optionally, refer to Figure 4 In this utility model, a fixing member 42 is provided on the lower side of the base 4, and the fixing member 42 clamps and fixes the rail web of the rail 5.

[0062] In this embodiment, before operation, the base 4 is fixedly installed on the rail using the fixing member 42, thereby preventing the base 4 from being pushed away by the reaction force of the hydraulic cylinder 31 during operation, which would affect work efficiency. Furthermore, the fixing member can be a C-type clamp structure with a polyurethane anti-slip pad on the inside, and the opening degree can be adjusted by a screw mechanism.

[0063] Furthermore, in this embodiment, the fixing member 42 can be selected as a screw, bolt or other fixing member to clamp the rail web of the rail 5 from both sides, thereby fixing the base 4 on the rail.

[0064] Optionally, a pressure relief valve 43 is provided on the base 4 in this utility model, and the pressure relief valve 43 is connected to the hydraulic cylinder 31.

[0065] In this embodiment, when the load pressure on the hydraulic cylinder 31 is too high, the pressure relief valve 43 automatically opens to overflow, protecting the hydraulic cylinder from overload damage. For example, when the adhesive layer is abnormally strong, causing the system pressure to exceed 16 MPa, the pressure relief valve 43 opens to overflow.

[0066] Optionally, both the base 4 and the mounting component 2 in this utility model are provided with lifting components on their upper sides.

[0067] In this embodiment, lifting components are provided on the base 4 and the mounting component 2 to facilitate lifting operations by the user, as well as hoisting and installation. Furthermore, the lifting component can be a cast lifting ring.
