[0002] With the increase in train speeds and the development of rail transportation, the requirements for railway vibration damping strips are also increasing. Railway vibration damping strips are key components in railway systems, used to absorb and reduce the vibration and noise generated by train operation. Typically made of elastic materials or special structures, they are installed between the track and the train wheels, or underneath the track, providing cushioning and vibration reduction. This design not only effectively protects the track structure from damage caused by long-term vibration, but also significantly improves passenger comfort, reduces noise pollution, and has a positive impact on the surrounding environment.
[0003] Railway shock-absorbing belts are generally composed of multiple groups of seismic isolation bearings. After a train passes through the shock-absorbing belt, the seismic isolation bearings will reset one by one. Due to the asynchronous reset time, the anchor rods used to fix the bearings will be subjected to a large tensile force. After long-term use, the anchor rods are easy to detach from the base under the track. Therefore, a pull-out resistant railway shock-absorbing belt seismic isolation bearing is proposed.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution for a pull-out resistant railway shock-absorbing belt isolation bearing, including a seismic isolation seat body 4, an upper connecting seat 1 is provided at the upper end of the seismic isolation seat body 4, a lower connecting seat 3 is provided at the lower end of the seismic isolation seat body 4, a damper 2 is provided between the upper connecting seat 1 and the lower connecting seat 3, and a docking mechanism 5 is connected to the upper connecting seat 1 and the lower connecting seat 3. The docking mechanism 5 includes a docking anchor rod 501 fixedly installed on the upper connecting seat 1 and the lower connecting seat 3, and an anti-pull assembly 6 is provided in the mounting slot 506. The piston 604 will drive the anti-pull push rod 605 to move forward, so that the anti-pull push rod 605 is pressed into the inside of the connecting groove on the base, thereby hindering the up and down movement of the docking anchor rod 501 and improving the pull-out strength of the docking anchor rod 501.
[0022] like Figure 2 and Figure 3 As shown, the docking mechanism 5 includes a docking anchor rod 501 fixedly mounted on the upper connecting seat 1 and the lower connecting seat 3, a mounting slot 506 is provided on the docking anchor rod 501, a mounting chamber 502 is provided on the docking anchor rod 501, a pressure sensor 505 is installed inside the mounting chamber 502, a detection probe rod 503 is movably installed above the pressure sensor 505, a reset spring 504 is sleeved on the detection probe rod 503, a fixed base 507 is provided at the bottom of the docking anchor rod 501, a mounting screw hole 508 is provided at the edge of the fixed base 507, a bolt is provided in the mounting screw hole 508, and the fixed base 507 is respectively fixed to the upper connecting seat 1 and the lower connecting seat 3 by bolts.
[0023] Specifically, the entire equipment can be installed on the base under the track through the docking anchor rod 501. A change in the reading of the pressure sensor 505 indicates that the docking anchor rod 501 is loose. When the docking anchor rod 501 is installed in the connecting groove, the detection probe 503 will contact the bottom of the connecting groove. When the docking anchor rod 501 is loose, it will move up and down. During the up and down movement of the docking anchor rod 501, the reset push rod 504 will pull the detection probe 503 away from the pressure sensor 505. At this time, the reading of the pressure sensor 505 will change, thereby reminding the staff to reinforce the anchor rod in time.
[0024] like Figure 2 and Figure 4 As shown, the anti-pullout component 6 includes a liquid cylinder 601 fixedly installed in the mounting slot 506, a docking nozzle 602 fixedly installed on the liquid cylinder 601, a one-way valve 603 is provided in the docking nozzle 602, a piston 604 is movably installed in the liquid cylinder 601, an anti-pullout ejector pin 605 is fixedly installed on the piston 604, an oil pipeline 606 is connected to the docking nozzle 602, a positioning groove is provided on the piston 604, and the anti-pullout ejector pin 605 is fixed on the piston 604 through the positioning groove.
[0025] Specifically, after the docking anchor 501 is installed in the connecting groove of the base, the hydraulic oil can be delivered to the hydraulic cylinder 601 through the delivery pipe 606, so that the piston 604 will move forward. After the piston 604 moves forward, it will drive the anti-pullout rod 605 to move forward, so that the anti-pullout rod 605 is pressed into the connecting groove on the base, thereby hindering the up and down movement of the docking anchor 501 and improving the pull-out strength of the docking anchor 501.
[0026] Working principle: When in use, the entire device can be installed on the base under the track. A connecting groove is provided in the base under the track, and the docking anchor rod 501 is installed in the connecting groove. After the docking anchor rod 501 is installed in the connecting groove, the hydraulic oil can be transported to the liquid cylinder 601 through the delivery pipe 606. Since the anti-pullout pin 605 is movably installed in the liquid cylinder 601 through the piston 604, the oil delivery pipe 606 is installed on the liquid cylinder 601 through the docking nozzle 602. The one-way valve 603 only allows the liquid in the oil delivery pipe 606 to enter the liquid cylinder 601 through the docking nozzle 602. Therefore, after the hydraulic oil is delivered to the liquid cylinder 601, the piston 604 will move forward. After the piston 604 moves forward, it will drive the anti-pullout rod 605 to move forward, and the anti-pullout rod 605 will be pressed into the base after moving forward. The connection groove on the docking anchor 501 is blocked, thereby hindering the up and down movement of the docking anchor 501, improving the pull-out strength of the docking anchor 501, and when the docking anchor 501 is installed in the connection groove, the detection probe 503 will hit the bottom of the connection groove. Since a movable groove is provided at the installation chamber 502, the detection probe 503 is movably installed in the installation chamber 502 through the movable groove, one end of the reset spring 504 is fixed on the detection probe 503, and the other end of the reset spring 504 is fixed at the movable groove in the installation chamber 502. Therefore, when the docking anchor 501 is loose, it will move up and down. During the up and down movement of the docking anchor 501, the reset push rod 504 will pull the detection probe 503 away from the pressure sensor 505. The change in the reading of the pressure sensor 505 indicates that the docking anchor 501 is loose, thereby reminding the staff to reinforce the anchor in time.
[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
