Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail laying technology, and in particular to an auxiliary bracket for rail laying. Background Technology
[0002] Currently, the laying of long rails in railway engineering is mainly handled using the WZ500 track laying machine. The WZ500 track laying machine mainly consists of a guide car, a rail-splitting pusher car (pusher car), and transition slope cars (transition slope car I, transition slope car II, and transition slope car III). The slope car primarily mitigates the height difference during long rail laying, reducing the impact of long rails on the ballasted track bed. The rail-splitting pusher car uses a winch to feed the long rails from the long rail transport car into the pushing device, adjusting the spacing between the two rails during the pushing process. The long rails are then laid through three high-speed rail sections... The trolley, positioned at the lowest slope, gradually descends onto the rollers placed on the ballast track bed. The rails travel along the rollers to the guide car and are suspended from it. The guide car pulls a 500m long rail along the rollers, using guide wheels on both sides to control the direction of travel. Finally, the long rail is lowered into the groove at the designated position and installed. However, the current trolleys use a fixed structure, which makes it difficult to alleviate the different height differences during the laying of long rails. Furthermore, the support plates on the trolleys are also fixed, causing the rails to slide unevenly when lowered into the groove.
[0003] Therefore, it is necessary to provide a new auxiliary bracket for track laying to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary bracket for track laying.
[0005] The auxiliary support bracket for track laying provided by this utility model includes a frame component, on which an auxiliary support component for supporting the track and a lifting component for adjusting the height of the auxiliary support component are installed.
[0006] The auxiliary support component includes a fixed base, on which a U-shaped support plate is rotatably connected and whose angle can be adjusted. The U-shaped support plate is equipped with multiple sets of rotatably connected guide rollers and a fixed frame with a limiting frame for limiting the track. The fixed base is equipped with a rotating frame, and a rotatably connected connecting sleeve is fitted on the rotating frame. The connecting sleeve is fixedly installed at the bottom of the U-shaped support plate. The fixed base also has an installation cavity, and a rotatably connected cylinder is installed in the installation cavity. The output end of the cylinder is rotatably installed on the lower surface of the U-shaped support plate away from the connecting sleeve via the rotating frame.
[0007] Preferably, corner support pads for supporting the U-shaped support plate are fixedly installed on the fixed seats on both sides of the mounting cavity.
[0008] Preferably, the frame component includes a crossbeam and a longitudinal beam, each of which has two beams and is fixedly connected in a "U" shape, and the bottom of the longitudinal beam is provided with rollers for the vehicle body to slide on the track.
[0009] Preferably, the lifting component includes a lead screw, which is rotatably mounted on two longitudinal beams, and a servo motor for driving the lead screw to rotate is mounted on the longitudinal beams. The lead screw is provided with two opposite threaded sections, and each threaded section is fitted with a threaded connecting seat. Side support assemblies are installed on both longitudinal beams, and the side support assemblies are connected to the threaded connecting seats through connecting columns.
[0010] Preferably, the side support assembly includes a sliding rod, which is fixedly installed in a groove on the longitudinal beam. Two slidingly connected sliders are sleeved on the sliding rod, and each slider is equipped with a rotatably connected central plate. A rotatably connected mounting plate is mounted on the top of the two central plates.
[0011] Preferably, connecting columns are fixedly installed on both sides of the threaded connector, and the other end of the connecting column is fixedly connected to the slider at the corresponding position in the side support assembly.
[0012] Preferably, the mounting base is fixedly mounted on the mounting plate.
[0013] Preferably, a U-shaped traction seat is fixedly installed on both of the crossbeams, and bolts are installed on the U-shaped traction seat.
[0014] Compared with related technologies, the auxiliary bracket for track laying provided by this utility model has the following advantages:
[0015] 1. This utility model adjusts the height of the auxiliary support component supporting the rail according to the needs by lifting the component, so that the height of the auxiliary support component on the mounting plate can be effectively adjusted. When lowering the rail, the height of the auxiliary support component on different auxiliary brackets is adjusted in a step-by-step manner. Specifically, the rail lowering point on the guide vehicle is the lowest, and then the auxiliary support components on the auxiliary brackets away from the guide vehicle are lowered in sequence with decreasing height, which facilitates the lowering and laying of the rail.
[0016] 2. The guide rollers on the U-shaped support plate in this utility model make it easier for the guide vehicle to slide the rail off the auxiliary bracket. The limiting frame prevents the rail from falling off the U-shaped support plate. When lowering the rail, the cylinder is activated to push the tail of the U-shaped support plate upward, so that the guide rollers on the U-shaped support plate tilt in the direction of lowering the rail. Since the auxiliary support components on the auxiliary bracket away from the guide vehicle descend in successive decreasing heights, the entire rail can be lowered in an inclined manner, making the lowering of the rail more convenient.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.
[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0024] Please see Figures 1 to 4 This utility model provides an auxiliary support bracket for track laying, which includes a frame component 1, an auxiliary support component 2, and a lifting component 3.
[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 The frame component 1 includes a crossbeam 11 and a longitudinal beam 12. Both the crossbeam 11 and the longitudinal beam 12 are provided with two beams and are fixedly connected in a "U" shape. The bottom of the longitudinal beam 12 is provided with a roller 13 for the vehicle body to slide on the track. Both crossbeams 11 are fixedly installed with U-shaped traction seats 4, and bolts 41 are installed on the U-shaped traction seats 4.
[0026] It should be noted that: multiple sets of auxiliary brackets (auxiliary bracket I, auxiliary bracket II, auxiliary bracket III, etc.) of this application are set on the slide rail and connected by a traction rod. Specifically, one end of the traction rod is inserted into the U-shaped traction seat 4 at the tail of auxiliary bracket I and rotated and connected by bolt 41, while the other end of the traction rod is inserted into the U-shaped traction seat 4 at the front of auxiliary bracket II and rotated and connected by bolt 41. The subsequent auxiliary bracket connection method is as above. Then, auxiliary bracket I is connected to the guide car by a traction rod. Subsequently, the rail is fed from the long rail transport car by a winch through the rail pusher car and passes through the guide roller 23 on the auxiliary bracket component 2 until the end of the rail is installed on the clamp on the guide car.
[0027] After the rails are transported to the laying area, the traction rods are removed one by one, and then the guide vehicle pulls the rails off the auxiliary brackets one by one.
[0028] In the embodiments of this utility model, please refer to Figures 1 to 4 The frame component 1 is equipped with an auxiliary support component 2 for supporting the track and a lifting component 3 for adjusting the height of the auxiliary support component 2. The lifting component 3 includes a lead screw 31, which is rotatably mounted on two longitudinal beams 12. A servo motor 32 for driving the lead screw 31 to rotate is mounted on the longitudinal beams 12. The lead screw 31 has two opposite threaded sections, and each threaded section is fitted with a threaded connecting seat 33. Side support assemblies 34 are mounted on both longitudinal beams 12. The side support assembly 34 includes a sliding rod 341. 1. It is fixedly installed in the groove opened on the longitudinal beam 12, and two sliding blocks 342 are sleeved on the sliding rod 341. Each slider 342 is equipped with a rotating connecting plate 343, and the top of the two connecting plates 343 is supported by a rotating mounting plate 344. The side support assembly 34 and the threaded connection seat 33 are connected by a connecting column 35. Specifically, the two side walls of the threaded connection seat 33 are fixedly installed with connecting columns 35, and the other end of the connecting column 35 is fixedly connected to the slider 342 at the corresponding position in the side support assembly 34.
[0029] It should be noted that the height of the auxiliary support component 2 supporting the rail can be adjusted according to the requirements. Specifically, the servo motor 32 is turned on to drive the lead screw 31 to rotate. Since the two opposite threaded sections on the lead screw 31 are fitted with threaded connecting seats 33, the two threaded connecting seats 33 drive the two sliders 342 in the side support assembly 34 to slide towards or away from each other through the connecting column 35. Therefore, the height of the auxiliary support component 2 installed on the mounting plate 344 can be effectively adjusted. When lowering the rail, the height of the auxiliary support component 2 on the auxiliary bracket I, auxiliary bracket II, auxiliary bracket III, etc. is adjusted in a step-by-step manner. Specifically, the rail on the guide car has the shortest descent height, and then the auxiliary support component 2 on the auxiliary brackets away from the guide car descends in succession with decreasing height, which facilitates the lowering and laying of the rail.
[0030] In the embodiments of this utility model, please refer to Figures 1 to 4 The auxiliary support component 2 includes a fixed base 21, which is fixedly mounted on the mounting plate 344. A U-shaped support plate 22, which is rotatably connected and whose angle can be adjusted, is mounted on the fixed base 21. Multiple sets of rotatably connected guide rollers 23 are mounted on the U-shaped support plate 22, and a limiting frame 24 for limiting the track is provided on the fixed frame. A rotating frame 211 is fixedly mounted on the fixed base 21, and a rotatably connected connecting sleeve 221 is sleeved on the rotating frame 211. The connecting sleeve 221 is fixedly mounted on the bottom of the U-shaped support plate 22. An installation cavity 21a is also provided on the fixed base 21, and a rotatably connected cylinder 25 is installed in the installation cavity 21a. The output end of the cylinder 25 is rotatably mounted on the side of the lower surface of the U-shaped support plate 22 away from the connecting sleeve 221 via the rotating frame.
[0031] It should be noted that the guide rollers 23 on the U-shaped support plate 22 make it easier for the guide vehicle to pull the rail off the auxiliary bracket. The limiting frame 24 can prevent the rail from falling off the U-shaped support plate 22. When the rail is lowered, the cylinder 25 is activated to push the tail of the U-shaped support plate 22 upward, so that the guide rollers 23 on the U-shaped support plate 22 tilt in the direction of lowering the rail. Since the auxiliary support components 2 on the auxiliary bracket away from the guide vehicle descend in successive decreasing heights, the entire rail can be lowered in an inclined manner, making the lowering of the rail more convenient.
[0032] In this embodiment, in order to facilitate the transport of steel rails on the arc track by auxiliary bracket I, auxiliary bracket II, auxiliary bracket III, etc., limit frames 24 of different widths can be replaced.
[0033] Furthermore, corner support pads 212 for supporting the U-shaped support plate 22 are fixedly installed on the fixed seats 21 on both sides, so that when the U-shaped support plate 22 is in a horizontal state, the bottom surface of the U-shaped support plate 22 away from the connecting sleeve 221 can be placed on the corner support pads 212, thereby improving the stability of the U-shaped support plate 22 when it is in a horizontal state.
[0034] The working principle of the auxiliary bracket for track laying provided by this utility model is as follows:
[0035] Multiple sets of auxiliary brackets (auxiliary bracket I, auxiliary bracket II, auxiliary bracket III, etc.) of this application are mounted on the slide rail and connected using traction rods. Specifically, one end of the traction rod is inserted into the U-shaped traction seat 4 at the tail of auxiliary bracket I and rotated and connected by bolt 41, while the other end of the traction rod is inserted into the U-shaped traction seat 4 at the front of auxiliary bracket II and rotated and connected by bolt 41. The subsequent connection method of the auxiliary brackets is as described above. Then, auxiliary bracket I is connected to the guide vehicle using a traction rod, and then the guide vehicle is pushed by a rail-splitting pusher using a winding... The winch delivers the rails from the long rail transport vehicle, allowing them to pass sequentially through the guide rollers 23 on the auxiliary support component 2 until the rail ends are installed on the clamps on the guide vehicle. The height of the rail support component 2 is adjusted as needed. Specifically, the servo motor 32 is activated to rotate the lead screw 31. Since the two opposite threaded sections on the lead screw 31 are each fitted with a threaded connecting seat 33, the two threaded connecting seats 33, through the connecting column 35, respectively drive the two sliders 342 in the side support assembly 34 to slide towards or away from each other. This causes the mounting plate 34... The height of the auxiliary support component 2 installed on the 4th bracket can be effectively adjusted. When lowering the rail, the height of the auxiliary support component 2 on auxiliary bracket I, auxiliary bracket II, auxiliary bracket III, etc., is adjusted in a step-by-step manner. Specifically, the rail on the guide car is lowered to the shortest height, and then the auxiliary support components 2 on the auxiliary brackets farther away from the guide car are lowered in successive steps with decreasing heights, thus facilitating the lowering and laying of the rail. The guide rollers 23 on the U-shaped support plate 22 make it easier for the guide vehicle to pull the rail off the auxiliary bracket. The limit frame 24 can prevent the rail from falling off the U-shaped support plate 22. When the rail is lowered, the cylinder 25 is activated to push the tail of the U-shaped support plate 22 upward, so that the guide rollers 23 on the U-shaped support plate 22 tilt in the direction of rail lowering. Since the auxiliary support components 2 on the auxiliary bracket away from the guide vehicle descend in succession with decreasing height, the entire rail can be lowered in an inclined manner, making the lowering of the rail more convenient.
