Railway arrival-departure line anti-slip pull rod force transmission mechanism

Abstract

This utility model discloses a force transmission mechanism for anti-slippage tie rods on railway arrival and departure lines, including a square box, force transmission rods, a power pull plate, and a force transmission hinge mechanism. The square box contains a first inner limiting slide rail and a second inner limiting slide rail that are perpendicularly connected to each other. The power pull plate is disposed through the second inner limiting slide rail. The force transmission rods are respectively disposed in the first inner limiting slide rails on both sides of the power pull plate. The two force transmission rods in the first inner limiting slide rails are connected to the power pull plate via the force transmission hinge mechanism. By driving the power pull plate to reciprocate in the second inner limiting slide rails, the force transmission hinge mechanism drives the two force transmission rods to reciprocate in the first inner limiting slide rails. This utility model's anti-slippage tie rod force transmission mechanism ensures that the linear input of the power pull plate is accurately converted into the equidistant reverse output of the two force transmission rods, thereby greatly improving the synchronization accuracy of the rail clamping action, eliminating the risk of unilateral clamping failure, and preventing slippage accidents.

Description

Technical Field

[0001] This utility model relates to the field of railway train anti-runaway technology, specifically a force transmission mechanism for anti-runaway tie rods on railway arrival and departure lines. Background Technology

[0002] In railway transportation systems, preventing derailment on arrival and departure tracks is a core aspect of ensuring train operation safety. Traditional anti-derailment devices generally employ screw-type jacks, hydraulic cylinder push-pull mechanisms, or simple linkage mechanisms to clamp the rails, which have significant drawbacks: screw drives are inefficient and prone to thread jamming; hydraulic systems are susceptible to oil leakage and performance degradation at low temperatures; and simple linkage mechanisms are prone to uneven wear due to their single force transmission path. Especially for anti-derailment rail clamping mechanisms requiring bidirectional synchronous drive (such as spring-loaded rail clamps, i.e., the railway arrival and departure track anti-derailment spring-loaded structure disclosed in the prior art with patent number 202222495588.5), existing technologies struggle to achieve equal force output and synchronized displacement of the tie rods on both sides, often resulting in insufficient clamping force on one side and causing derailment accidents. To address these issues, there is an urgent need for a dedicated force transmission mechanism that is highly efficient and precisely synchronized to meet the high-reliability anti-derailment requirements of modern railway arrival and departure tracks. Utility Model Content

[0003] This utility model addresses the above-mentioned problems and overcomes the shortcomings of the existing technology by providing a force transmission mechanism for anti-slippage tie rods on railway arrival and departure lines.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a force transmission mechanism for anti-slip levers on railway arrival and departure lines, comprising a square box, force transmission rods, a power pull plate, and a force transmission hinge mechanism. The square box is provided with a first inner limiting slide rail and a second inner limiting slide rail that are perpendicularly connected to each other. The power pull plate is disposed through the second inner limiting slide rail. The force transmission rods are respectively disposed in the first inner limiting slide rails on both sides of the power pull plate. The two force transmission rods in the first inner limiting slide rails are connected to the power pull plate via the force transmission hinge mechanism. By driving the power pull plate to reciprocate in the second inner limiting slide rails, the force transmission hinge mechanism drives the two force transmission rods to reciprocate in the first inner limiting slide rails.

[0005] Preferably, the force transmission hinge mechanism includes force transmission plates, force transmission guide wheels, and pins. The force transmission plates are symmetrically arranged on both sides of the power pull plate. The pins include a first pin and a second pin. One end of each of the two force transmission plates is connected to the power pull plate via the first pin, and the other end of each of the two force transmission plates is connected to one end of each of the two force transmission rods via the second pin. The two ends of the second pin are sleeved with force transmission guide wheels. The force transmission guide wheels are in contact with the first inner limit slide of the square box and the force transmission rods. The force transmission guide wheels can roll along the first inner limit slide of the square box without rolling out of the square box. With the assistance of the force transmission guide wheels, the two force transmission rods can easily reciprocate within the first inner limit slide.

[0006] Preferably, the ends of the two force transmission rods exposed outside the square box are provided with U-shaped connecting ears, and connecting shafts are provided on the U-shaped connecting ears.

[0007] Preferably, both ends of the power pull plate are provided with connection holes.

[0008] Preferably, the square box, the force transmission rod, and the power pull plate are all provided with weight reduction holes.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This railway arrival and departure line anti-slippage tie rod force transmission mechanism, through a structural design combining a square box, force transmission rod, power pull plate, and force transmission hinge mechanism, fundamentally solves the technical problem of bidirectional synchronous force transmission in the field of railway anti-slippage. Firstly, by employing a rigid guide frame formed by mutually perpendicular first and second inner limit slides, combined with the symmetrically arranged force transmission plates and pin structures in the force transmission hinge mechanism, it ensures that the linear input of the power pull plate is accurately converted into the equidistant reverse output of the two force transmission rods, thereby greatly improving the synchronization accuracy of the rail clamping action, eliminating the risk of unilateral clamping failure, and preventing slippage accidents. Secondly, by forming a rolling pair between the force transmission guide wheel and the first inner limit slide, traditional sliding friction is transformed into rolling friction, reducing transmission resistance, significantly reducing power consumption, and avoiding jamming.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a force transmission mechanism for anti-slip levers on railway arrival and departure lines, comprising a square box 6, force transmission rods 3, a power pull plate 7, and a force transmission hinge mechanism. The square box 6 is provided with a first inner limiting slide rail 5 and a second inner limiting slide rail 10 that are perpendicularly connected to each other. The power pull plate 7 is disposed through the second inner limiting slide rail 10. The force transmission rods 3 are respectively disposed in the first inner limiting slide rails 5 on the left and right sides of the power pull plate 7. The two force transmission rods 3 in the first inner limiting slide rails 5 are connected to the power pull plate 7 through the force transmission hinge mechanism. The power pull plate 7 is driven by a motor to reciprocate in the second inner limiting slide rail 10, thereby the force transmission hinge mechanism drives the two force transmission rods 3 to reciprocate in the first inner limiting slide rail 5. The force transmission hinge mechanism includes two force transmission plates 12, four force transmission guide wheels 4, and three pins. The force transmission plates 12 are symmetrically arranged on the left and right sides of the power pull plate 7. The pins include one first pin 11 and two second pins 13. One end of the two force transmission plates 12 is connected to the power pull plate 7 through the first pin 11, and the other end of the two force transmission plates 12 is connected to one end of the two force transmission rods 3 through the second pins 13. Both ends of the second pins 13 are fitted with force transmission guide wheels 4. The force transmission guide wheels 4 are in contact with the first inner limit slide 5 of the square box 6 and the force transmission rods 3. The force transmission guide wheels 4 can roll along the first inner limit slide 5 of the square box 6 without rolling out of the square box 6. With the assistance of the force transmission guide wheels 4, the two force transmission rods 12 can easily reciprocate in the first inner limit slide 5.

[0018] Specifically, the ends of the two force transmission rods 3 exposed outside the square box 6 are each provided with U-shaped connecting ears 2, and connecting shafts 1 are provided on the U-shaped connecting ears 2. The two force transmission rods 3 can be connected to the anti-runaway spring pressure structure of the railway arrival and departure lines through the U-shaped connecting ears 2 and connecting shafts 1 at the ends, together forming the anti-runaway device of the railway arrival and departure lines. It is used in conjunction with the train track to clamp and fix the wheels of the train that stops at the station to prevent the train from running away.

[0019] Specifically, both ends of the power pull plate 7 are provided with connection holes 8. Since multiple anti-slipping tie rod force transmission mechanisms of this utility model are required to form a railway arrival and departure line anti-slipping device, the function of the connection holes 8 at both ends of the power pull plate 7 is to facilitate the sequential connection of multiple anti-slipping tie rod force transmission mechanisms of this utility model. In this way, the connection holes 8 at both ends of the power pull plate 7 support the series expansion of multiple tie rod force transmission mechanisms, which can be adapted to station lines of different lengths. The U-shaped connecting ear 2 realizes quick docking with the anti-slipping spring pressure structure.

[0020] Specifically, the square box 6, the force transmission rod 3, and the power pull plate 7 are all provided with weight reduction holes 9, which can reduce the overall weight of the anti-slip pull rod force transmission mechanism of the railway arrival and departure lines.

[0021] The working principle of this utility model is explained in conjunction with its technical solution and accompanying drawings: Under the power transmission of the motor, the power plate 7 can reciprocate back and forth along the second inner limit slide 10 of the square box 6; simultaneously, it can drive the force transmission plates 12 and force transmission guide wheels 4 on both sides of the power plate 7 to move, thereby driving the force transmission rod 3 to reciprocate in the first inner limit slide 5, that is, the force transmission rod 3 is pushed out and pulled back in the first inner limit slide 5, thus realizing the force transmission between the power plate 7 and the force transmission rod 3; Figure 1 The diagram shown illustrates the state of the two force transmission rods 3 during their extension; as shown... Figure 5 The diagram shown is a state diagram of the two force transmission rods 3 when they are pulled back.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
