Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and more specifically, to a high-speed turnout transport vehicle. Background Technology

[0002] High-speed railway turnouts are critical equipment on rail transit lines, enduring frequent impacts from train wheelsets. Long-term operation can lead to wear and even damage to key components such as the turnout tips and frog rails, posing a potential threat to train safety. Once a turnout is severely damaged, it must be replaced promptly. Currently, the commonly used method for replacing No. 18 single turnouts typically requires a long "maintenance window," occupying the track for extended periods and severely impacting the operational efficiency of high-speed railways. Therefore, how to shorten the turnout replacement time and improve construction efficiency is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0003] In view of this, this utility model proposes a fast turnout transport vehicle, which aims to solve the problem of excessively long construction time for high-speed turnout replacement in the prior art. By setting up a gantry crane and reinforcement device, the turnout can be replaced quickly, safely and efficiently.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a high-speed turnout transport vehicle, including a powered vehicle and at least one unpowered vehicle. The unpowered vehicle is equipped with a gantry crane for loading and unloading and a reinforcement device for fixing the components. The reinforcement device includes a multi-layered frame, each layer of which is equipped with a slider that can move on the frame beam. The gantry crane consists of a base a, a hydraulic motor, a telescopic beam, a column, a lifting point, a telescopic column, a telescopic hydraulic cylinder, a base b, and a lateral hydraulic cylinder. The base a is rotatably fixed to the unpowered vehicle and is driven to rotate by the hydraulic motor, which is hidden inside the base a. The telescopic hydraulic cylinder is hidden inside the telescopic column. The lateral hydraulic cylinder is located at the top of the gantry crane. When the lateral hydraulic cylinder extends, it drives the telescopic beam, the telescopic hydraulic cylinder, the telescopic column, the base b, and the lifting point to move horizontally together.

[0005] According to one embodiment of the present invention, the slider can translate on the frame in a direction perpendicular to the extension direction of the rail. The slider is fixed to the rail by bolts. When the high-speed turnout transport vehicle passes through a curve, the slider can translate on the frame to compensate for the lateral displacement caused by the curve and reduce or offset the deformation of the component in the curve.

[0006] According to one embodiment of the present invention, the rapid turnout transport vehicle consists of three unpowered vehicles, each with a length of approximately 25 meters.

[0007] According to one embodiment of this utility model, three unpowered vehicles and one powered vehicle are used, and the unpowered vehicles are equipped with nine reinforcement devices. According to another embodiment of this utility model, the unpowered vehicles are equipped with six gantry cranes, two on each unpowered vehicle, located at both ends of the unpowered vehicle.

[0008] The beneficial effects of this utility model are as follows: Improve operational efficiency: By innovatively designing a reinforcement device with automated loading and unloading functions, and working with a gantry crane to achieve rapid and accurate component transfer, the efficiency of turnout replacement has been improved.

[0009] Enhanced transportation safety: The slider of the reinforcement device can move horizontally inside the frame, that is, on the frame beam. Under the lateral displacement compensation mechanism, it can offset the lateral stress on the turnout components when the vehicle is turning, effectively preventing the components from deforming during transportation and ensuring transportation quality.

[0010] Improved on-site operational convenience: High-precision hoisting solutions are available: The improved gantry crane structure makes its erection and retraction more efficient and stable, ensuring the precise hoisting of large turnout components. Attached Figure Description

Detailed Implementation 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] A high-speed turnout transport vehicle includes a powered vehicle (7) and at least one unpowered vehicle (8). The unpowered vehicle (8) is equipped with a gantry crane (9) for loading and unloading and a reinforcement device (10) for securing the components. The reinforcement device (10) includes a multi-layered frame (11), each layer of which is provided with a slider (12) movable on a frame beam. The gantry crane (9) consists of a base a (15), a hydraulic motor (16), a telescopic beam (14), a column (21), a lifting point (20), and a telescopic column (18). It consists of a telescopic hydraulic cylinder (17), a base b (19), and a transverse hydraulic cylinder (22); the base a (15) is rotatably fixed on the unpowered vehicle (8) and is driven to rotate by a hydraulic motor (16). The hydraulic motor (16) is hidden inside the base a (15), the telescopic hydraulic cylinder (17) is hidden inside the telescopic column (18), and the transverse hydraulic cylinder (22) is located on the upper part of the gantry crane. When the transverse hydraulic cylinder (22) extends, it drives the telescopic beam (14), the telescopic hydraulic cylinder (17), the telescopic column (18), the base b (19), and the lifting point (20) to move together.

[0018] The slider (12) can translate on the frame (11) in the direction perpendicular to the extension of the rail. The slider (12) is fixed to the rail by bolts (13). When the high-speed turnout transport vehicle passes through the curve, the slider (12) can translate on the frame (11) to compensate for the lateral displacement caused by the curve and reduce or offset the deformation of the component in the curve.

[0019] The high-speed turnout transport vehicle consists of three unpowered vehicles (8), each with a length of approximately 25 meters.

[0020] Three unpowered vehicles (8) and one powered vehicle (7) are used, and the unpowered vehicles (8) are equipped with nine reinforcement devices (10). The unpowered vehicle (8) is equipped with six gantry cranes, with two cranes on each unpowered vehicle (8), located at the front and rear ends of the unpowered vehicle (8).

[0021] Specific implementation process: Figure 5The image shows a reinforcement device 10 on a non-powered vehicle. The reinforcement device consists of a frame 11 and a slider 12. The frame 11 is divided into three layers: upper, middle, and lower, allowing components I to IV to be stacked simultaneously, reducing the volume occupied. The slider 12 can move vertically along the extension direction of the rail on the frame 11, and the slider 12 is fixed to the rail by bolts 13. Figure 5 The image on the left shows a high-speed turnout transport vehicle traveling on a straight road. Figure 5 The right side shows the situation when the high-speed turnout transport vehicle passes through a curve. It can be seen that the two fixed devices are not on the same straight line. At this time, the slider 12 can be translated on the frame 11 to compensate for the lateral displacement caused by the curve and reduce or offset the deformation of components I~IV in the curve.

[0022] The disassembled components I-IV are placed on one side of the unpowered vehicle 8 and then hoisted onto the unpowered vehicle 8 using the gantry crane 9. The powered vehicle 7 and the unpowered vehicle 8 together form a rapid turnout transport vehicle, which is then transported to the turnout replacement site.

[0023] The structure of gantry crane 9 is as follows Figure 4 As shown, the gantry crane 9 consists of a base a15, a hydraulic motor 16, a telescopic beam 14, a column 21, a lifting point 20, a telescopic column 18, a telescopic hydraulic cylinder 17, a base b19, and a lateral hydraulic cylinder 22. The base a15 is fixed to the unpowered vehicle 8. The hydraulic motor 16 is concealed within the base a15, and the telescopic hydraulic cylinder 17 is concealed within the telescopic column 18. During operation, the hydraulic motor 16 drives the column 21, telescopic beam 14, telescopic column 18, base b19, lifting point 20, lateral hydraulic cylinder 22, and telescopic hydraulic cylinder 17 to rotate together. After rotating to the predetermined position, the lateral hydraulic cylinder 22 extends, causing the telescopic beam 14, telescopic hydraulic cylinder 17, telescopic column 18, base b19, and lifting point 20 to move horizontally together. After being moved to the predetermined position, the telescopic hydraulic cylinder 17 extends, causing the telescopic column 18 to extend as well, and driving the base b19 to the predetermined position. At this point, the gantry crane with base a15 and base b19 as the force-bearing points is erected.

[0024] When the gantry crane 9 is retracted, the telescopic hydraulic cylinder 17 is retracted first, along with the telescopic column 18 and the base b19. Then, the lateral hydraulic cylinder 22 retracts, driving the telescopic hydraulic cylinder 17, the telescopic column 18, the base b19, and the lifting point 20 to retract as well. Finally, the hydraulic motor 16 rotates, driving the column 21, the telescopic measuring rod 14, the telescopic column 18, the base b19, the lifting point 20, the lateral hydraulic cylinder 22, and the telescopic hydraulic cylinder 17 back to the retracted position.

[0025] Upon arrival at the replacement site, the track laying process begins with the arrival of personnel and equipment. Simultaneously, the following steps are completed: cutting the rails, positioning the track vehicle, de-energizing the overhead contact system, loosening the switch fasteners, and dismantling the electrical equipment. The high-speed switch transport vehicle is then parked on the adjacent track at the switch replacement location. After completing steps such as old rail removal, new rail installation, securing the new rail, and initial track adjustment, the high-speed switch transport vehicle can leave the site with the old rails. Simultaneously, on-site, the following steps are completed sequentially according to the drawings: rough adjustment of geometric dimensions, fine adjustment, welding, grinding, cooling, flaw detection, single-sided installation of the HRS external track device (step 1), installation of the pull-down device, comprehensive track inspection, switch area grinding, single-sided installation of the HRS external track device (step 2), and commissioning. After inspection, confirmation, and power-on, personnel leave by vehicle, and the line is finally opened. (Using reasonable...) Figure 1 The disassembly method of turnouts in China and Figure 2 After the high-speed turnout transport vehicle in the middle, according to Figure 3 After reviewing the flowchart, the overall time is calculated to be controllable within 360 minutes.
