Description

Technical Field

[0001] This utility model relates to a turnout stabilization device, belonging to the technical field of turnout construction equipment. Background Technology

[0002] For ballasted railways, turnout tracks, like main lines, will experience ballast compaction and deformation after a period of use, affecting traffic safety. Therefore, after periodic maintenance operations such as cleaning and tamping, turnout stabilization devices are needed to stabilize the turnout tracks, compensating for the weakening of lateral resistance and overall stability caused by tamping, and ensuring the ballast is re-compacted and arranged to meet normal traffic safety requirements. The working principle of turnout stabilization devices is to apply a vertical static load and horizontal excitation force to the track, causing the ballast to move, fill, and compact. The key lies in the reliable transmission of appropriate horizontal vibration; that is, the entire stabilization device must maintain its structural safety and reliability and the continuous stability of its operational effect under the continuous generation of horizontal excitation force at a specific frequency.

[0003] Traditional mainline stabilization devices are ineffective for stabilizing turnout lines. Existing turnout stabilization devices often employ a vertical dual-vibration-shaft arrangement. This structure results in a high center of gravity, large relative torque to the rails, and poor operational stability. It not only affects the smoothness of the stabilization device's movement but also makes its own mechanisms, such as the clamping cylinders, prone to leakage and damage. For example, patent application number 202410160127.3 discloses a dynamic stabilization vehicle and its track stabilization device, which uses a vertical six-axis excitation coupled with a driver for vertical drive. While this structure lowers the center of gravity of the vibration shafts, the vertically arranged driver raises the overall center of gravity. Furthermore, the longitudinal arrangement of the six axes means that the longitudinal force along the rail caused by installation errors cannot be offset by the vertical downward pressure. Combined with the significantly increased overall width of the vibration components, this ultimately reduces operational stability and affects the stabilization effect. Additionally, the existing stabilization devices suffer from unreasonable force on the clamping cylinders, leading to premature wear of the cylinder seals and a short service life. Therefore, a turnout stabilization device is needed to solve the problems of existing turnout track stabilization devices, which use vertical vibration shafts for excitation drive, resulting in a high center of gravity, poor structural stability, and low safety in use.

[0004] The purpose of this invention is to provide a turnout stabilization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a turnout stabilization device, comprising a housing and a vibration assembly, the vibration assembly comprising a main vibration shaft and a driven vibration shaft arranged in parallel; the two ends of the main vibration shaft and the driven vibration shaft are rotatably mounted on the housing, and the driven vibration shaft is symmetrically located on both sides of the main vibration shaft in the horizontal direction, and the axes of the main vibration shaft and the driven vibration shaft are located on the same horizontal plane; eccentric blocks are respectively provided on the main vibration shaft and the driven vibration shaft, and the main vibration shaft is connected to a power drive component; a main drive gear is provided on the main vibration shaft, and a driven gear is provided on the driven vibration shaft, the main drive gear and the driven gear meshing.

[0008] Specifically, the housing is also equipped with a clamping assembly, which includes a clamping cylinder, a lever plate, a clamping body, and clamping wheels. The clamping bodies are rotatably mounted on the end face of the housing facing the turnout track, and clamping wheels are mounted on the clamping bodies. The lever plate is rotatably mounted on the housing above the clamping bodies, and the end of the clamping body away from the clamping wheels is hinged to the lever plate via a connecting rod. The end of the lever plate away from the connecting rod is hinged to the power end of the clamping cylinder. The cylinder body of the clamping cylinder away from the power end is hinged to the housing.

[0009] Specifically, there are two clamping assemblies, which are symmetrically installed on both sides of the housing facing the turnout track.

[0014] Specifically, the two active vibration shafts of the stabilization device group are driven by their respective power drive components, or the two active vibration shafts are connected as one unit through a transmission shaft and are driven by one of the power drive components of the two turnout stabilization devices.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The turnout stabilizing device of this application includes a housing and a vibration assembly. The vibration assembly includes a main vibration shaft and a driven vibration shaft arranged in parallel, with the axes of the main vibration shaft and the driven vibration shaft located on the same horizontal plane. To achieve the turnout stabilizing device, a horizontal multi-axis vibration shaft arrangement is adopted, which effectively lowers the overall center of gravity, making the overall structure of the turnout stabilizing device of this application simple, compact, and with higher reliability and safety.

[0017] 2. Based on the foregoing, the driven vibration shafts of this application are symmetrically located on both sides of the main vibration shaft in the horizontal direction, and the number of driven vibration shafts is at least two. The main vibration shaft and the driven vibration shaft of this application are each provided with an eccentric block, and the main vibration shaft is connected to a power drive component; the main vibration shaft is provided with a main drive gear, and the driven vibration shaft is provided with a driven gear, the main drive gear and the driven gear meshing; the eccentric block on the main vibration shaft is defined as a first eccentric block, and the eccentric block on the driven vibration shaft is defined as a second eccentric block. The main drive gear and the first eccentric block are sleeved on the main vibration shaft, and the driven gear and the second eccentric block are respectively sleeved on the driven vibration shaft, and the excitation force generated by the first eccentric block is twice the excitation force generated by all the second eccentric blocks. This allows the main vibration shaft to drive the driven vibration shaft through gear meshing, which in turn drives the first and second eccentric blocks to rotate, generating bidirectional horizontal excitation forces. Meanwhile, the vertical excitation forces generated by the second eccentric blocks on both sides can cancel the vertical excitation forces generated by the first eccentric block at any phase angle, thus satisfying the force couple balance, preventing the turnout stabilizing device from overturning during operation, improving the operational stability of the device, and enhancing the excitation quality.

[0018] 3. Based on the foregoing, the housing of this application is further provided with a clamping assembly, which includes a clamping cylinder, a lever plate, a clamping body, and a clamping wheel. Clamping bodies are rotatably mounted on the end face of the housing facing the turnout track. Clamping wheels are mounted on the clamping bodies. A lever plate is rotatably mounted on the upper side of the housing. The end of the clamping body away from the clamping wheel is hinged to the lever plate via a connecting rod. When the clamping cylinder of this application drives the lever plate to drive the connecting rod to push the clamping wheel to clamp the turnout track, the clamping cylinder is set in a horizontal state. This ensures that the clamping cylinder is in a horizontal state during clamping, improving the force distribution on the clamping cylinder, avoiding oil leakage caused by uneven long-term stress on the internal seals, and improving product reliability. Furthermore, the output force of the clamping cylinder is in the same direction as the clamping force of the clamping wheel, improving the transmission efficiency of the clamping force, i.e., generating a greater clamping force under the same cylinder oil pressure.

[0019] 4. Based on the foregoing, the number of turnout stabilizing devices in this application is at least one, and when the number is greater than one, two turnout stabilizing devices can form a stabilizing device group. This allows for the selection of one or more turnout stabilizing devices to form a combined stabilizing device group for operation according to the requirements of railway turnout operation, thereby improving operational efficiency.

[0020] 5. Based on the foregoing, the two active vibration shafts of the stabilizing device group in this application are driven by their respective power drive components, or the two active vibration shafts are connected as a whole via a transmission shaft and driven by one of the power drive components in the two stabilizing device groups. This allows for selection of the power drive component to drive each stabilizing device according to operational requirements. This type of stabilizing device group has low torque on the power drive component, reducing wear and tear and lowering maintenance costs. In contrast, a stabilizing device group where the two active vibration shafts are connected as a whole via a transmission shaft is driven by the power drive component of one of the stabilizing devices. This type of stabilizing device group requires only one power drive component, simplifying control and reducing the overall failure rate. However, the individual power drive component may have a short service life due to heavy load. The turnout stabilizing device of this application allows users to choose the appropriate option based on their usage, resulting in high product applicability. Attached Figure Description

[0029] Please see Figures 1-6 This embodiment discloses a turnout stabilization device, including a housing 4 and a vibration assembly 1, comprising a main vibration unit 1-1 and two driven units, defined as a first driven unit 1-2 and a second driven unit 1-3. The main vibration unit 1-1 includes a main vibration shaft 1-1-1, a main drive gear 1-1-2, and a first eccentric block 1-1-3.

The first driven vibration shaft and the second driven vibration shaft are symmetrically located on both sides of the main vibration shaft in the horizontal direction, and the axes of the main vibration shaft, the first driven vibration shaft, and the second driven vibration shaft are located on the same horizontal plane. In this embodiment, the main drive gear 1-1-2 and the first eccentric block 1-1-3 are respectively sleeved on the main vibration shaft 1-1-1, and the main vibration shaft is connected to the power end of the first motor 7. The first driven gear 1-2-2 and the second eccentric block 1-2-3 are respectively sleeved on the first driven vibration shaft, and the second driven gear 1-3-2 and the second eccentric block 1-3-3 are respectively sleeved on the second driven vibration shaft. The main drive gear 1-1-2 meshes with the first driven gear 1-2-2 and the second driven gear 1-3-2 respectively.

[0030] In this embodiment, the bottom of the housing is provided with a roller assembly 3, which includes a roller shaft, a support cylinder 3-2, and a roller 3-1. Roller shafts are slidably installed at the four corners of the bottom of the housing in the horizontal direction. Support cylinders are symmetrically installed on the end face of the housing that is perpendicular to the turnout track 5, and the two sides of the support cylinders are respectively connected to the roller shafts on the end face. Rollers are rotatably installed on the side of the roller shaft facing the turnout track. Vertical cylinders 6 are symmetrically provided in the vertical direction of the housing.

[0031] Furthermore, in this embodiment, the housing 4 is also provided with two clamping assemblies 2, which are symmetrically installed on both sides of the housing facing the turnout track. The clamping assembly 2 includes a clamping cylinder 2-1, a lever plate 2-2, a clamping body 2-4, and a clamping wheel 2-5; wherein, in this embodiment, the clamping bodies 2-4 are rotatably installed on the bottom end faces of both sides of the housing 4 facing the turnout track 5, and the clamping wheels 2-5 are rotatably installed on the clamping bodies; the lever plates 2-2 are rotatably installed on both sides of the housing above the clamping bodies, and the clamping bodies on both sides corresponding to the lever plates are hinged to the lever plates through connecting rods 2-3; and the clamping cylinders are hinged to the end faces of the housing corresponding to the lever plates, and the end of the lever plate away from the connecting rod is hinged to the power end of the clamping cylinder. In addition, in this embodiment, when the clamp cylinder 2-1 drives the lever plate 2-2 to drive the connecting rod 2-3 to push the clamp wheel 2-5 to clamp the turnout track 5, the clamp cylinder 2-1 is set in a horizontal state.

[0032] The excitation force generated by the first eccentric block 1-1-3 in this embodiment is twice the excitation force generated by all the second eccentric blocks, namely the second eccentric block 1-2-3 and the second eccentric block 1-3-3.

[0033] Furthermore, this embodiment uses two turnout stabilizing devices, which together form a stabilizing device group. The two active vibration shafts of the stabilizing device group in this embodiment have two connection methods, see [link to relevant documentation]. Figure 5 The first type: The two active vibration shafts of the stabilizing device assembly are driven by their respective first motors 7. (See also...) Figure 6 The second type: the two active vibration shafts of the stabilization device group are connected as one unit through the transmission shaft 8, and are driven by the first motor of one of the two turnout stabilization devices.

[0034] Working Principle: In this embodiment, the turnout stabilizing device, driven by a vertical cylinder, pushes the housing vertically downward. The roller assembly's support cylinder drives the roller shaft to press the rollers tightly against the inside of the turnout track. On the outside of the track, the clamping cylinder of the clamping assembly drives a lever plate to move a connecting rod, which in turn clamps the outside of the track via clamping wheels. The turnout stabilizing device is fixed to the turnout track by the roller assembly and clamping assembly. When stabilization is required, a first motor drives the main vibration shaft to rotate, which in turn drives the main drive gear and the first eccentric wheel to rotate. The main drive gear, through gear meshing, drives two driven gears to rotate in opposite directions, which in turn drives two driven vibration shafts to rotate, which in turn drives two second eccentric wheels to rotate. This generates a horizontal bidirectional excitation force at a specific frequency. The excitation force is transmitted to the turnout track through the housing, roller assembly, and clamping assembly to complete the turnout stabilization operation.

[0035] Please see Figure 7 The principle that the turnout stabilizing device of this embodiment can generate a horizontal bidirectional excitation force at a specific frequency is that the calculation formula of the excitation force generated by the eccentric block in this embodiment is: F=meω2;

[0036] In the above formula: F is the excitation force generated by the eccentric block, in N; m is the mass of the eccentric block, in kg;

[0037] e is the eccentricity of the eccentric block, in meters (m); ω is the angular velocity of the eccentric block, in rad / s.

[0038] According to the above formula, the excitation force generated by the first eccentric wheel of the turnout stabilizing device in this embodiment is F2, while the excitation force generated by the two second eccentric wheels is F1. Since the excitation force generated by the first eccentric block is twice the excitation force generated by all the second eccentric blocks, i.e., F2 = 2xF1, and the torque of the second eccentric wheels on both sides relative to the axis of the main vibration shaft is 0. During the stabilization operation excitation process, when the main vibration shaft rotates and its rotation drives the vibration component to be in phase 0, the excitation force generated by the first eccentric wheel is balanced with the torque generated by the two second eccentric wheels, and the excitation force is F0 = F2 - 2F1 = 0, that is, there is no excitation force in the horizontal direction. When the vibration component is at 90° phase, the excitation force generated by the first eccentric wheel and the force generated by the two second eccentric wheels are along the center of rotation, without generating a couple. At this time, the excitation force is horizontal to the left, and the excitation force is F = F2 + 2F1 = 4F1 = 2F2. When the vibration component is at 180° phase, the excitation force generated by the first eccentric wheel and the couple generated by the two second eccentric wheels are balanced, and the excitation force is F = 2F1 - F2 = 0, that is, no excitation force is generated in the horizontal direction. When the vibration component is at 270° phase, the excitation force generated by the first eccentric wheel and the force generated by the two second eccentric wheels are along the center of rotation, without generating a couple. At this time, the excitation force is horizontal to the right, and the excitation force is F = F2 + 2F1 = 4F1 = 2F2. Therefore, it can be concluded that the vibration component of the turnout stabilization device in this embodiment, driven by the first motor, will generate horizontal excitation force according to the 90° phase and the 27° phase, and the excitation force of the two phases is in opposite directions, thereby generating an excitation force of a specific frequency that varies with the speed of the first motor.

[0039] The embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. For those skilled in the art, after learning the contents of the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
