[0030] As attached Figure 1 -Attached Figure 5 As shown, the utility model provides an auxiliary tool for replacing and removing a rail, comprising a sleeper connecting section 1, an inclined section 2, and a rail accommodating section 3 arranged in sequence. The sleeper connecting section 1, the inclined section 2, and the rail accommodating section 3 are rod structures. The sleeper connecting section 1 is used to fix the auxiliary tool for replacing and removing a rail on a sleeper 5 of a railway, and the inclined section 2 is used to connect the sleeper connecting section 1 and the rail accommodating section 3.
[0031] The inclined section 2 is inclined upward from the tail end of the sleeper connecting section 1, that is, the tail end of the inclined section 2 is higher than the sleeper connecting section 1;
[0032] The rail accommodating section 3 includes a first side stop 31 extending downward from the rear end of the inclined section 2, a bottom support portion 32 extending from the lower end of the first side stop 31 toward an end away from the sleeper connecting section 1, and a second side stop 33 extending upward from the bottom support portion 32. The first side stop 31, the bottom support portion 32, and the second side stop 33 connected in sequence form a U-shaped structure, which can stably and reliably store the old rail 6.
[0033] It also includes an insulating layer 4 arranged outside the sleeper connecting section 1, the inclined section 2 and the rail accommodating section 3 to ensure that the old rail can be electrically insulated from the online rail after removal, ensuring the safety of railway transportation and personnel, and can buffer the pressure of the auxiliary tools for replacing and removing the rail on the rail and sleeper.
[0034] When replacing and removing the rails, the removed old rail 6 is placed on the sleeper connecting section 1, and then the old rail 6 is pushed into the rail accommodating section 3 after passing through the inclined section 2 and temporarily stored in the rail accommodating section 3, and finally the old rail 6 is removed from the rail accommodating section 3;
[0035] Among them, on the one hand, the inclined section 2 can increase the height of the first side stop 31, ensuring that the old rail 6 will not tilt toward the rail installation side after being placed in the rail accommodating section 3. On the other hand, the inclined section 2 also provides an oblique transition during the pushing process of the old rail 6, and can provide certain support and buffering effects when the staff pushes the old rail 6 from the sleeper connecting section 1 into the rail accommodating section 3. While facilitating support and saving effort, it can also prevent the old rail 6 from entering the rail accommodating section 3 too quickly, so as not to damage the disassembled old rail 6. After the old rail 6 is placed in the rail accommodating section 3, the old rail 6 can be stored stably and reliably, ensuring the stability and reliability of the temporary storage of the old rail 6. The provision of the insulating layer 4 ensures that the old rail 6 can be electrically insulated from the online rail after disassembly, ensuring the safety of railway transportation and staff, and can buffer the pressure of the auxiliary tools for replacing and disassembling the rail on the rail and the sleeper.
[0036] In one embodiment, the upper end of the first side stop 31 is higher than the upper end of the second side stop 33. This further prevents the old rail 6 from tipping over toward the rail installation side after being placed in the rail accommodating section 3. When the old rail 6 is removed from the rail accommodating section 3, the lower height of the second side stop 33 makes it easier to remove the old rail 6. In one embodiment, the height of the first side stop 31 is 125 mm to 135 mm, preferably 130 mm, and the height of the second side stop 33 is 65 mm to 70 mm, preferably 67.5 mm.
[0037] In one embodiment, the sleeper connecting section 1 is higher than the bottom supporting portion 32. At this time, the sleeper connecting section 1 is supported on the sleeper 5, and the bottom supporting portion 32 is located at the upper end of the sand and gravel outside the sleeper 5, which can reduce the protruding distance of the upper ends of the inclined section 2 and the rail accommodating section 3. In one embodiment, the sleeper connecting section 1 is 55mm-65mm higher than the bottom supporting portion 32, preferably 60mm.
[0038] In one embodiment, the interval between the first side stop 31 and the second side stop 33 is 160 mm-170 mm, preferably 165 mm. The interval of 160 mm-170 mm can ensure that the use requirements of multiple specifications of rails are met.
[0039] In one embodiment, the angle between the inclined section 2 and the sleeper connecting section 1 is 140°-145°, preferably 143°, which ensures the flatness of the inclined section 2 and further simplifies the difficulty of pushing the old rail 6 from the inclined section 2 into the rail accommodating section 3.
[0040] In one embodiment, refer to the attached Figure 5 The length of the sleeper connecting section 1 plus the inclined section 2 is greater than the length of the outer side of the sleeper 5, that is, the inclined section 2 can be at the outer end of the sleeper 5. This not only shortens the operating distance of the old rail 6, but also minimizes the deformation of the rail accommodating section 3 after the old rail 6 is placed.
[0041] In one embodiment, refer to the attached Figure 2 , the outer walls of the sleeper connecting section 1, the inclined section 2 and the rail accommodating section 3 are provided with an insulating layer 4, so as to keep the old rail 6 insulated from the rail. Preferably, the insulating layer 4 is a polyurethane layer. By providing the insulating layer 4, on the one hand, it can provide the necessary buffering for the rail accommodating section 3 when placing the old rail 6 and bumping, and at the same time protect the operator and avoid bumping caused by the operator. Preferably, the thickness of the insulating layer 4 on the side close to the rail is 20 mm to avoid damage to the insulating layer 4 during tightening and squeezing, and the thickness of the side of the rail accommodating section 3 in contact with the rail is 7 mm to improve the buffering performance of both and ensure the reliability of the product during use. The other thicknesses are 5 mm thick to ensure the buffering capacity and the effect of protecting the operator. In addition, the insulating layer 4 is provided, and when the sleeper connecting section 1 is installed, there is no need to install a gasket between the sleeper connecting section 1 and the sleeper 5, which can simplify the installation process and reduce the difficulty of installation.
[0042] In one embodiment, the sleeper connecting section 1, the inclined section 2 and the rail accommodating section 3 are square tubes. The sleeper connecting section 1, the inclined section 2 and the rail accommodating section 3 are preferably formed in one piece. The square tube is used so that the bottom of the sleeper connecting section 1 and the rail accommodating section 3 is a flat structure, so that the contact surface between the sleeper connecting section 1 and the sleeper 5, and the rail accommodating section 3 and the old rail 6 is more fitted, thereby improving the safety of operation and use. Preferably, the specification of the square tube is 25mm*25mm, and sealing plates are welded at both ends of the square tube for sealing.
[0043] In this embodiment, a steel plate 11 is welded to the end of the sleeper connecting section 1 on the side facing away from the inclined section 2, and a mounting hole is provided on the steel plate 11. The diameter of the mounting hole is preferably 28 mm. When in use, the sleeper connecting section 1 is fixed by installing fixing bolts on the mounting hole. The steel plate 11 provides the necessary size, rigidity and strength for the connection between the sleeper connecting section 1 and the sleeper 5. Preferably, the entire welded steel plate 11 is also coated in a polyurethane layer. Preferably, the upper end of the steel plate 11 is flush with the upper end of the square tube of the sleeper connecting section 1, and the thickness of the steel plate 11 is preferably 12 mm. At this time, the thickness of the polyurethane layer on the side of the steel plate 11 close to the sleeper 5 is 20 mm, which greatly ensures the insulation performance and prevents the steel plate 11 from contacting the sleeper 5. In a specific embodiment, the total length of the auxiliary tool for replacing and disassembling the rail is 732 mm, and the length of the sleeper connecting section 1 is 400 mm.
[0044] The present invention also provides a rail replacement and disassembly system, which comprises a plurality of auxiliary tools for rail replacement and disassembly arranged along the length direction of the rail, thereby being able to dismantle and install a longer old rail 6.
