Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, specifically to a switch rail fork bridge type passage device. Background Technology

[0002] As the lifeline of national economic development and the core of the transportation system, the safe and efficient operation of railways plays an irreplaceable role in ensuring national economic stability and harmonious social development. In the daily maintenance and upkeep of the railway system, the replacement and adjustment of rails and forks are crucial links in ensuring railway line quality and guaranteeing traffic safety.

[0003] In the routine maintenance and repair of railway lines, it is often necessary to replace or transport heavy components such as rails and switch points during maintenance windows (railway operation gaps). When the transport route needs to pass through the switch point area or switch point area, the switch is usually locked during the maintenance window, the switch point and stock rail are tightly fitted, and the switch point itself has special geometric structures such as harmful spaces, which prevent the wheel flanges of the rail-lifting trolley from passing through these areas normally and smoothly. In the existing technology, the rails or switch points are usually unloaded from the rail-lifting trolley, and a large number of people are organized to move them laterally to the adjacent track. After the rail-lifting trolley passes through the obstacle area empty, the components are re-lifted and finally moved back to their original position. The process is cumbersome, time-consuming, and labor-intensive, affecting maintenance efficiency and potentially delaying the restoration of normal railway operation. Moreover, it poses multiple safety hazards. Frequent loading and unloading and manual movement of heavy rails can easily cause safety accidents such as personnel collisions, pinching injuries, or components falling.

[0004] Therefore, there is an urgent need to provide a switch rail fork bridge type passage device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and defects of the existing technology and provide a point rail fork bridge type passer, which improves work efficiency, effectively reduces safety risks during operation, and enhances the stability of the overhead rail trolley during operation.

[0006] The objective of this utility model is achieved through the following technical solution: A switch rail fork bridge type passage device, characterized in that it assists the overhead rail trolley in pushing the rail or fork across the railway switch rail area and fork rail area, comprising: The main bridge frame has a bearing plane at its upper end for supporting the overhead rail trolley, and the bearing plane is adapted to the wheel flange of the overhead rail trolley; the main bridge frame extends along the length of the railway track and is erected on the upper end of the track; A ramp structure is provided at both ends of the main bridge frame, and the ramp structure is used to allow the suspended rail trolley to drive steadily up and down the main bridge frame; A positioning structure is provided at the side end of the main bridge frame for adjustingly fixing the main bridge frame onto the track.

[0010] Optionally, the ramp structure is made of square steel.

[0011] Optionally, the main cable tray side end is provided with multiple sets of stabilizing structures at intervals along the length extension direction. The stabilizing structure includes a mounting groove and a stabilizing plate. The mounting groove passes through the side end of the main cable tray, and the stabilizing plate is detachably connected to the mounting groove and is arranged parallel to the upper end surface of the track.

[0012] Optionally, the main bridge frame includes a first bridge section and a second bridge section, which are detachably connected, and the two inclined structures are respectively located at opposite ends of the first bridge section and the second bridge section.

[0023] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0024] This utility model proposes a switch rail fork bridge type passage device, which is used to assist the suspended rail trolley in pushing the rail or fork through the switch rail area and fork area of ​​the railway.

[0025] Reference Figures 1 to 5 In this embodiment, it includes: The main bridge frame 1 has a bearing plane 111 at the upper end for supporting the overhead rail trolley, and the bearing plane 111 is adapted to the wheel flange of the overhead rail trolley; the main bridge frame 1 extends along the length of the railway track and is erected on the upper end of the track; The ramp structure 2 is located at both ends of the main bridge frame 1. The ramp structure 2 is used to allow the trolley to smoothly drive up and down the main bridge frame 1. Positioning structure 4 is located at the side end of the main cable frame 1 and is used to adjustably fix the main cable frame 1 onto the track.

[0026] Optionally, in this embodiment, the switch rail fork bridge-type passage includes a main bridge frame 1, a ramp structure 2, and a positioning structure 4. The ramp structure 2 is located at both ends of the main bridge frame 1 to allow the hoisting trolley to pass through. That is, when the hoisting trolley pushes the rail or fork, it moves upward through the ramp structure 2 and connects to the main bridge frame 1 after moving upward. The design of the ramp structure 2 can effectively reduce the friction and collision between the passage and the switch rail, so that the hoisting trolley can pass through more smoothly and reach the main bridge frame 1 more easily. The upper end of the main bridge frame 1 is provided with a bearing plane 111, which is used to support the hoisting trolley. The wheel flange of the hoisting trolley is adapted to the bearing plane 111 to prevent the hoisting trolley from deviating in direction when passing through, which would cause the trolley to fall off the main bridge frame 1 and cause equipment damage and personnel injury. The main bridge 1 extends along the length of the railway and is erected on the upper end of the track to guide the trolley. The positioning structure 4 is located on the side of the main bridge 1 and is used to fix the main bridge 1. When the hoisting trolley enters the ramp structure 2 and the main bridge 1, it prevents the friction generated from causing the main bridge 1 and the ramp structure 2 to slide along the extension direction of the track, causing the main bridge 1 to derail or slide along the track. The size of the positioning structure 4 is adjustable. That is, depending on different situations, even if the distance between the switch rail 62 and the basic track 61 is different, the size of the positioning structure 4 can be adjusted to make the track and the main bridge 1 able to be positioned and connected, preventing the main bridge 1 from sliding.

[0027] Specifically, in railway maintenance, when pushing rails or forks using a hoisting trolley, upon reaching the turnout or fork area, the turnout is closed and cannot be manually switched. Furthermore, the switch rail is usually tightly fitted with the main track 61, preventing the hoisting trolley from passing normally. Manual operation is required to load and unload the rails or forks, move them to another track, and then hoist them again after passing through the switch rail area. This process is time-consuming, labor-intensive, and poses significant safety hazards. By installing a switch rail 62 fork bridge-type passer, the rails or forks can be smoothly pushed to their destination without repeatedly moving the switch rail 62 and transporting the rails and forks, greatly improving work efficiency, effectively reducing safety risks during operation, and enhancing the stability of the hoisting trolley during operation with the positioning structure 4.

[0028] Optionally, refer to Figure 1 and Figure 2 In this embodiment, the main cable tray 1 includes square steel sections and channel steel sections, which are alternately arranged along the length of the main cable tray 1. The channel steel has a vertical web and two horizontal flanges, which gives it excellent strength when subjected to vertical bending stress. In the main cable tray 1, the channel steel can serve as the main load-bearing component, bearing the vertical load of the trolley, rail, or fork, preventing the main cable tray 1 from bending and deforming in the middle. The square steel has good bending and torsional stiffness in all directions. In the structure, the square steel can play a role in connection, support, and stability, connecting multiple channel steels into a whole to prevent lateral torsion or instability of the structure. The square steel sections and channel steel sections are alternately arranged along the length of the main cable tray 1 and then welded. The channel steel is responsible for bearing the main weight, while the square steel, as a connector, is responsible for maintaining the stability and rigidity of the overall structure. Moreover, square steel and channel steel are common profiles with low cost and regular shapes that are suitable for welding. A robust and integrated structure is manufactured through welding. Furthermore, in this embodiment, the upper surface of the main bridge frame 1 is set parallel to the track, making the hoisting trolley move more easily and quickly during travel. Moreover, the size of the main bridge frame 1 is adapted to the track, which can prevent the main bridge frame 1 from easily falling off the track when the hoisting trolley is traveling.

[0029] Furthermore, in this embodiment, the ramp structure 2 is made of square steel. Square steel is typically solid with a rectangular cross-section, making it ideal for ramp cutting. One end can be smoothly cut and ground into a ramp that gradually rises from the ground to the bridge frame. This ramp is crucial for the smooth passage of the hoisting trolley, guiding its wheels to smoothly ascend and descend from the bridge frame, avoiding severe impacts and bumps. The ramp structure 2 includes a ramp section 21, a connecting section 22, and an abutting section 23. The connecting section 22 and the abutting section 23 are located at opposite ends of the ramp section 21. The connecting section 22 is fixedly connected to the main bridge frame 1, and the abutting section 23 abuts against the rail. The connecting section 22, the ramp section 21, and the abutting section 23 form a complete ramp structure 2, enabling the hoisting trolley to smoothly ascend and descend from the bridge frame.

[0030] Optionally, refer to Figure 1 In this embodiment, the main cable tray 1 has multiple sets of stabilizing structures spaced apart along its length. Each stabilizing structure includes a mounting groove 31 and a stabilizing plate 32. The mounting groove 31 passes through the side of the main cable tray 1, and the stabilizing plate 32 is detachably connected to the mounting groove 31. The mounting groove 31 is located near the bottom of the main cable tray 1, meaning the stabilizing plate 32 is located close to the bottom of the main cable tray 1. The stabilizing plate 32 is parallel to the upper surface of the track. When the hoisting trolley travels to the fork center area, due to the large number of tracks, the stabilizing plate 32 in the mounting groove 31 abuts against the upper surface of the track as the hoisting trolley travels along the main cable tray 1, preventing the hoisting trolley from causing the main cable tray 1 to tip over or deviate. At the same time, the detachable connection of the stabilizing plate 32 also facilitates the assembly and carrying of the device.

[0031] Optionally, refer to Figure 1 and Figure 2 In this embodiment, the main cable tray 1 includes a first section 11 and a second section 12, which are detachably connected. Two ramp structures 2 are respectively located at the two ends of the first section 11 and the second section 12 that are far apart from each other, i.e., opposite ends. The detachable connection facilitates the transportation and length adjustment of the main cable tray 1, and can be adjusted according to the size of the switch rail area and the fork center area. In other embodiments, the main cable tray 1 can be integrally formed or divided into two or more sections. When the main cable tray 1 is integrally formed, it is convenient for the production and processing of the main cable tray 1, and the overall stability of the main cable tray 1 is better. When the main cable tray 1 is divided into two or more sections, the two ramp structures 2 are respectively set on the first section and the last section, and no ramp structures 2 are set in the middle section. By adding or removing the number of middle sections, the length of the main cable tray 1 can be adjusted to adapt to various switch rail areas and fork center areas, and it is also convenient to carry and assemble. This is not limited here.

[0032] In this embodiment, the positioning structure 4 includes a wire rope 41 and a fixing member 42. One end of the wire rope 41 is connected to the stabilizing plate 32, and the other end is connected to the fixing member 42. The fixing member 42 is used to fix the connection to the switch rail 62. The wire rope 41 and the stabilizing plate 32 are detachably connected. The length or number of turns of the wire rope 41 can be selected according to the distance between the switch rail 62 and the basic track 61. Then the fixing member 42 is fixedly connected to the switch rail 62. If the length of the wire rope 41 is too long, the wire rope 41 is wound on the track and then the fixing member 42 is fixed. The fixing member 42 can be a hook or a clamp.

[0033] In this embodiment, a limiting structure is also provided on the side end of the main cable tray 1. The limiting structure includes a fixed section 51 and a limiting section 52. The limiting section 52 is connected to the main cable tray 1 through the fixed section 51. The limiting section 52 extends away from the upper end of the main cable tray 1 and is parallel to the side end of the main cable tray 1. It is used to limit the main cable tray 1 in the horizontal direction, preventing the main cable tray 1 from swaying horizontally and deviating from the track. The fixed section 51 is used to connect the limiting section 52 and the main cable tray 1. The limiting structure further prevents the main cable tray 1 from swaying horizontally. Furthermore, in this embodiment, a buffer pad is provided on the contact surface between the abutment section 23 and the track. The buffer pad provides a buffer between the device and the track, preventing damage to the device or the track.

[0034] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
