Description

Technical Field

[0001] The present invention relates to the field of turnout lifting tools, and particularly to a turnout lifting tool.

[0002] The present invention also relates to a method for adjusting the center of gravity of a turnout lifting tool.

[0003] The present invention also relates to a ground support system for a turnout lifting tool.

[0004] The present invention also relates to a ground support method for a turnout lifting tool. Background Art

[0005] As a key component of the railway line, the railway turnout has a complex structure, a large weight and uneven distribution, resulting in its physical center of gravity often seriously deviating from the geometric center. In traditional lifting operations, a turnout lifting tool (or called a balance beam) is usually used for lifting. The standard operation process is: the crane hook is connected to the central lifting point of the turnout lifting tool, and the turnout lifting tool is connected to the turnout through the lifting belts on both sides.

[0006] The prior art has the following two main technical problems: Lateral eccentricity problem: When the center of gravity of the turnout deviates towards one side of the turnout lifting tool (perpendicular to the length direction of the turnout lifting tool), the horizontal rotation angle of the turnout lifting tool can be finely adjusted to align the lifting point directly above the center of gravity, and the problem is relatively easy to solve.

[0007] Longitudinal eccentricity problem: When the center of gravity of the turnout deviates towards one end of the turnout lifting tool (along the length direction of the turnout lifting tool), after lifting, it will cause the turnout lifting tool and the turnout to tilt severely along the length direction, posing a safety hazard and being difficult to correct.

[0008] To solve the longitudinal eccentricity problem, the prior art (such as the special lifting tool for turnout loading and unloading in CN215208020U) proposes a solution, that is, a hook hanger that can move along the length direction is provided on the top of the turnout lifting tool. However, this solution requires integrating complex transmission or mechanical devices inside the turnout lifting tool, which not only significantly increases the manufacturing cost and structural complexity of the turnout lifting tool, but also may weaken the structural strength and reliability of the turnout lifting tool itself. Summary of the Invention

[0009] The purpose of the present invention is to provide a turnout lifting tool, a method for adjusting the center of gravity, a ground support system and a method, so as to solve the problems that the traditional method of changing the total center of gravity of the turnout lifting tool and the turnout increases the manufacturing cost and structural complexity of the turnout lifting tool, and also weakens the structural strength and reliability of the turnout lifting tool itself.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] This solution proposes a switch hanger and its center - of - gravity dynamic adjustment system, aiming to achieve safe, precise, and efficient switch hoisting balance control without changing the main - structure strength of the switch hanger and the position of the hanging point.

[0025] Referring to Figure 1 , the switch hanger of this solution basically follows the mature structure of the traditional working beam, including: working beam 1, central hook hanger 2, and side hanger (the side hanger is not shown in the figure).

[0026] The working beam 1 is a steel - structure beam that bears the main load. The central hook hanger 2 is located at the geometric center of the top of the working beam 1. The central hook hanger 2 is used to connect the hook of the crane. A number of side hangers are located on both sides of the working beam 1 and are distributed along the length direction of the working beam 1. The side hangers are used to connect the flexible hoisting belt, and the flexible hoisting belt is used to bypass the bottom of the switch to connect the switch to the side hangers.

[0027] Referring to Figure 2In order to adjust the center of gravity position of the working beam 1, a center of gravity adjustment system is additionally integrated on the top of the working beam 1, which includes: a load platform 11, a trolley track 12, a transport trolley 3 and several counterweights 4.

[0028] The load platform 11 is two parallel track-type vertical walls arranged along the length of the working beam 1. The top of the platform has been specially treated (with higher friction or a slot that matches the counterweight 4) to stably carry the modular counterweight 4. The counterweight 4 is designed as a standard weight that can ride astride the two vertical walls.

[0029] The sub-trolley track 12 is located between the two load platforms 11, and its track surface is lower than the top surface of the platform.

[0030] The transport vehicle 3 is a miniature vehicle that can move autonomously on the vehicle track 12 . The transport vehicle 3 includes a moving system 31 and a lifting system 32 .

[0031] The traveling system 31 is used to drive the transport trolley 3 to move along the trolley track 12 and enable it to have a certain climbing ability, so that when the heights of the two ends of the working beam 1 are different, the transport trolley 3 can still carry the counterweight 4 to move.

[0032] The lifting system 32 includes a push rod or platform driven by a hydraulic cylinder to be raised and lowered on the top of the transport vehicle 3. The lifting system 32 is used to lift the counterweight 4 on the load platform 11 from the bottom, so that the transport vehicle 3 can transport the counterweight 4 with the assistance of the walking system 31, thereby placing the counterweight 4 to a new position.

[0033] The working principle of the center of gravity adjustment system: By controlling the reciprocating motion of the transport trolley 3 on the top of the working beam 1, the distribution of all counterweights 4 on the working beam 1 is actively and accurately changed, thereby dynamically adjusting the center of gravity of the switch spreader itself. When the switch spreader is connected to the eccentric switch, the center of gravity adjustment system can rearrange the position of the counterweight 4 to move the combined center of gravity of the combination of the working beam 1 and the counterweight 4 to offset the eccentric torque of the switch, thereby ensuring that the total center of gravity of the working beam 1, counterweight 4 and switch is exactly below the fixed lifting point of the crane, thereby achieving horizontal balance of the working beam 1.

[0034] In order to prevent the central hook hanger 2 from interfering with the movement of the transport trolley 3 and the counterweight 4, the lever arm 21 connecting the central hook hanger 2 and the working beam 1 is designed to bypass the trolley track 12 and the load platform 11 to connect the central hook hanger 2 and the two sides of the working beam 1.

[0035] Furthermore, in order to realize the automated management (addition, reduction, storage) of the counterweight 4 and the maintenance of the transport vehicle 3, this solution designs a ground support system that matches the turnout spreader. The ground support system is integrated into the dedicated rail vehicle for transporting the spreader.

[0036] Reference Figure 3 , the ground support system includes: a positioning fixture 5, a warehouse beam 6, and a handling mother vehicle 7.

[0037] The positioning fixture 5 is used to firmly fix and position the working beam 1 on the rail vehicle, ensuring its absolute stability during counterweight adjustment.

[0038] The warehouse beam 6 has another set of load platforms 11 and sub-vehicle tracks 12 that are exactly the same as the load platform 11 and sub-vehicle track 12 at the top of the working beam 1. The warehouse beam 6 is placed parallel to the working beam 1 on the positioning fixture 5, and the corresponding track heights and spacings are exactly the same. Its main function is to store the counterweight 4 and park the handling sub-vehicle 3.

[0039] The handling mother vehicle 7 is a transport vehicle that can move horizontally back and forth between the ends of the working beam 1 and the warehouse beam 6. Its tabletop is also provided with a sub-vehicle track 12 and can be seamlessly docked with the sub-vehicle tracks 12 of the working beam 1 and the warehouse beam 6.

[0040] Reference Figure 4 , the cooperative working mechanism of the center of gravity adjustment system and the ground support system: The handling sub-vehicle 3 carries the counterweight 4 and travels from the end of the track of the working beam 1 (or the warehouse beam 6) to the handling mother vehicle 7. The handling mother vehicle 7 then moves horizontally to the end of the warehouse beam 6 (or the working beam 1), and the sub-vehicle then travels from the handling mother vehicle 7 to the target beam. This design realizes the automatic transfer of the sub-vehicle and the counterweight 4 between the working beam 1 and the warehouse beam 6.

[0041] Furthermore, to ensure that after the working beam 1 is lifted onto the rail vehicle, the working beam 1 can be aligned with the handling mother vehicle 7 on the positioning fixture 5, so that the handling sub-vehicle 3 can move along the substantially seamless sub-vehicle track 12. The positioning fixture 5 is designed with an active alignment function, aiming to ensure that the working beam 1 lifted back onto the rail vehicle can be accurately aligned with the mother vehicle, providing a seamless track transfer path for the handling sub-vehicle 3.

[0042] Reference Figure 5 , the positioning fixture 5 includes: a roller table 51, a positioning push rod 52, and a thrust mechanism 53.

[0043] The roller table 51 is fixedly installed on the rail vehicle. It includes several special-shaped rollers 54 with concave centers. The concave surface of the special-shaped roller 54 is designed to carry the bottom surface of the working beam 1, and the two ends of the special-shaped roller 54 are designed as tapered enlarged-diameter structures, so as to play a passive guiding role when the working beam 1 is placed, making the working beam 1 automatically move closer to the center of the roller, and realizing the lateral alignment of the center line of the working beam 1 and the center line of the roller table 51.

[0044] The positioning push rod 52 is usually a linear actuator such as a cylinder. The positioning push rod 52 is installed at one end of the roller table 51 and is used to apply a thrust to the working beam 1 to make the working beam 1 move longitudinally along the roller table 51.

[0045] The thrust stop mechanism 53 is usually a hydraulic buffer or a precision stop block. The thrust stop mechanism 53 is installed at the other end of the roller table 51. When the positioning push rod 52 pushes the working beam 1 and its end closely contacts the thrust stop mechanism 53, the working beam 1 reaches the preset longitudinal precise positioning point, and the sub-car track 12 at its end is precisely aligned with the track of the handling mother vehicle 7 at this time.

[0046] Furthermore, to make full use of the limited transportation area of the rail vehicle, the storage beam is designed as a multi-layer three-dimensional structure from top to bottom. The structure of each layer of the storage beam is exactly the same as the load platform 11 and the sub-car track 12 on the top of the working beam 1. This design realizes the three-dimensional and high-density storage of the counterweight 4.

[0047] To cooperate with the multi-layer storage beam, the handling mother vehicle 7 is an intelligent handling device with two-dimensional movement ability and can transfer the counterweight 4 and the handling sub-vehicle 3 between the working beam 1 and any layer of the storage beam.

[0048] Reference Figure 6 , the handling mother vehicle 7 includes: a handling platform 71, a lift 72, and a traversing machine 73.

[0049] The upper surface of the handling platform 71 is provided with a sub-car track 12 that can be seamlessly docked with the working beam 1 and the storage beam.

[0050] The lift 72 is usually a hydraulic lift 72 (such as a scissor lift and a gantry lift) and is used to drive the handling platform 71 to lift in the vertical direction so that it can accurately reach and align with the storage beam levels at different heights.

[0051] The traversing machine 73 is usually an electric slide (such as a synchronous belt slide and a lead screw slide) and is used to drive the entire lift 72 and the handling platform 71 to move reciprocally in the horizontal direction between the working beam 1 and the multi-layer storage beam.

[0052] The cooperative working mechanism of the handling mother vehicle 7 and the handling sub-vehicle 3: When it is necessary to transfer the counterweight 4, the traversing machine 73 first moves the handling mother vehicle 7 to the end of the working beam 1 (or the storage beam), and then the lift 72 adjusts the handling platform 71 to the target height and aligns the tracks. The handling sub-vehicle 3 can then carry the counterweight 4 and freely shuttle between the working beam 1, the mother vehicle, and the storage beam to achieve efficient, flexible, and three-dimensional material allocation.

[0053] Overall, the cooperative working method of the switch hoist, the center of gravity adjustment system, and the ground support system includes the following steps: Step 1, Preparation Stage: Before the hoisting operation, the working beam 1, the warehouse beam 6, the handling trolley 3, and the handling mother vehicle 7 are all located on the transport rail vehicle.

[0054] Step 2, Pre-configure the counterweight 4: According to the type, weight, and known eccentricity data (which can be pre-calculated or marked on the turnout) of the turnout to be hoisted, the staff, through the control system, instructs the trolley and the handling mother vehicle 7 to work together, pick up the required number of counterweights 4 from the warehouse beam 6, and transfer them to the working beam 1. In the initial state, these counterweights 4 will be evenly distributed to ensure that the center of gravity of the working beam 1 itself is at the geometric center.

[0055] Step 3, Hoisting and Dynamic Balance: Connect the working beam 1 to the turnout. The system automatically calculates according to the eccentric moment of the turnout or the operator inputs instructions to drive the trolley to move one or more counterweights 4 on the working beam 1 for precise position redistribution, ultimately causing the combined center of gravity of the working beam 1 and the counterweights 4 to shift, and the resulting balancing moment to roughly offset the overturning moment of the turnout.

[0056] Step 4, Hoisting Operation: After the center of gravity of the working beam 1 is adjusted, hoisting is carried out. At this time, the working beam 1 will basically remain horizontal. After the turnout is hoisted in place, the handling trolley 3 restores the counterweights 4 on the beam to the initial even distribution state, and then the staff separates the working beam 1 from the turnout.

[0057] Step 5, Reset the Counterweight 4: If there is no need to hoist eccentric loads (such as hoisting ordinary rails) subsequently, the working beam 1 can be lifted back to the positioning fixture 5 on the rail vehicle. The roller table 51 of the positioning fixture 5 first completes the lateral self-centering of the working beam 1, and then the positioning push rod 52 is activated to longitudinally push the working beam 1 until it contacts the thrust mechanism 53 to achieve precise alignment of the working beam 1 with the handling mother vehicle 7. Then, through the coordinated work of the handling trolley 3 and the handling mother vehicle 7, all the counterweights 4 and the handling trolley 3 are moved back to the warehouse beam 6 to reduce the self-weight of the working beam 1.

[0058] The advantages of this solution are as follows: The active control mode of "adjusting its own center of gravity to offset eccentricity" is used to replace the traditional passive mode of "adjusting the lifting point to adapt to the center of gravity", which improves the flexibility and adaptability of the system. And the integrated handling trolley and handling mother vehicle 7 achieve fully automatic and intelligent center of gravity allocation, reducing manual intervention and improving the operation efficiency and accuracy.

[0059] The center of gravity adjustment system is attached to the top of the working beam 1 without changing the main load-bearing structure of the working beam 1, ensuring the structural strength and safety of the turnout lifting device to the greatest extent.
