AI Technical Summary

Technical Problem

When the existing derailment device drives the switch point rail to switch, the rigid connection between the actuating rod and the switch point rail causes torque to affect the connection performance and installation status, resulting in uneven force on the structure, which affects the installation of the switch point rail and its own structure.

Method used

The vertical rod frame hook and switch rail connection iron assembly converts torque into a rotating pair. The design of the bent tie rod and vertical rod frame assembly reduces the torque impact on the switch rail, and the connection is stabilized by anti-loosening nuts and insulating plate structure.

Description

Technical Field

[0001] This invention relates to the field of railway machinery technology, specifically to a derailment actuator rod structure. Background Technology

[0002] A derailer is a protective device on the tracks used to protect personnel or important locomotives and rolling stock. It derails the train if a locomotive or rolling stock enters the track to ensure the safety of the protected object. Derailers are installed at both ends of freight trains during arrival inspections. If a locomotive slips, the derailer will force it off the track to protect lives. Derailers are also installed at both ends of some other important locomotives and rolling stock to protect their safety.

[0003] In conventional derailment actuators, the switch machine directly moves the turnout switch rail during switch rail switching. However, in existing technology, the driving force of the switch machine is applied directly to the turnout switch rail through the end of the actuator. To overcome the friction of the turnout switch rail itself during movement, a certain torque is generated between the actuator end and the switch rail during force switching due to the rigid connection between the actuator end and the switch rail. This torque can easily affect the connection performance between the actuator and the switch rail, and uneven force application at the end can impact the installation status and structure of the turnout switch rail. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] In conventional derailment devices, the actuating rod directly moves the turnout switch rail via the switch machine during switch rail switching. However, in existing technology, the driving force of the switch machine is directly applied to the turnout switch rail through the end of the actuating rod. To overcome the friction during the movement of the turnout switch rail itself, a certain torque is generated between the actuating rod end and the turnout switch rail during force switching due to the rigid connection between the actuating rod end and the switch rail. This torque can easily affect the connection performance between the connecting parts and the switch rail, and uneven force application at the end can negatively impact the installation state and structure of the turnout switch rail. Therefore, this embodiment proposes a derailment device, such as... Figure 1 As shown, it includes an operating lever 3, a switch machine 1, and an indicator lever 2; the switch machine 1 is mounted on the turnout sleeper via a switch machine 1 support plate; the two ends of the indicator lever 2 are connected to the indicator lever 2 of the switch machine 1 and the turnout switch rail, respectively.

[0026] like Figure 2-4 As shown, the actuating rod 3 includes a bent tie rod 31, a vertical rod frame assembly 36, and a switch rail connecting iron 37. One end of the bent tie rod 31 is connected to the output end of the switch machine 1; the vertical rod frame assembly 36 includes a vertical rod frame hook head with a sleeve shape 364 at the bottom and a vertical rod frame hook head 362 at the top; the sleeve shape 364 is fixedly installed at the other end of the bent tie rod 31; one side of the switch rail connecting iron 37 has a groove; the vertical rod frame hook head 362 is rotatably disposed in the groove; the other side of the switch rail connecting iron 37 is connected to the switch switch rail; wherein, the bent tie rod 31 drives the switch switch rail through the switch machine 1 to realize the switch rail switching.

[0027] Specifically, such as Figure 2 As shown, one end of the bent tie rod 31 has a slot; the output end of the switch machine 1 is rotatably connected to the slot of the bent tie rod 31 via a rotating pin 32. The other end of the bent tie rod 31 is a threaded section; the other end of the bent tie rod 31 is threadedly connected to two symmetrical bushings 35, each bushing 35 having an end plate at its outward end; the sleeve shape 364 of the vertical rod frame assembly 36 is slidably fitted onto the two bushings 35 and located between the two end plates; the outward ends of the two bushings 35 are fixed and limited by an anti-loosening nut 33 threadedly connected to the bent tie rod 31; a retaining ring 34 is provided between the anti-loosening nut 33 and the bushing 35; the outer end of the anti-loosening nut 33 is fixed by a protective nut 38. By adjusting the two bushings 35, the idle stroke is given, and the turnout switch rail is made to fit tightly as required.

[0028] like Figure 3 As shown, the vertical pole hook 362 has a rotating hole, in which a bearing 361 is installed; one end of a pin 375 passes through the switch rail connecting iron 37 and the bearing 361, and is fixedly connected to the inner ring of the bearing 361; the end of the pin 375 is fixed by an anti-loosening cap 376. To stably fix the bearing 361, a screw 363 is threaded through and connected to the top of the vertical pole hook 362, and the end of the screw 363 abuts against the oil injection hole of the outer ring wall of the bearing 361.

[0029] like Figure 4 As shown, the switch rail connecting iron 37 is connected to the turnout switch rail by at least two bolts; the other side of the switch rail connecting iron 37, in contact with the turnout switch rail, is covered with an L-shaped outer insulating plate 371; the bottom of the groove of the switch rail connecting iron 37 has at least two mounting holes, each containing an insulating tube 373; the bottom of the groove has an inner insulating plate 372; the bolts pass sequentially through the turnout switch rail, the outer insulating plate 371, the insulating tube 373, and the inner insulating plate 372, and are fixedly connected by fixing nuts 374. Preferably, an anti-loosening clip is connected between the two fixing nuts 374; an anti-loosening washer 377 and a gasket are provided between the inner insulating plate 372 and the fixing nuts 374.

[0030] The device proposed in this embodiment, when driving the switch point rail conversion via the actuating rod, uses a vertical rod hook head 362 and a switch rail connecting iron 37 to convert the torque applied to the switch rail into a rotating pair and release it, thereby reducing the impact on the switch rail and connection performance, as well as the impact on the switch rail installation state and its own structure caused by uneven end force.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
