Description

Technical Field

[0001] The present application relates to the technical field of engineering vehicles, and particularly to a rail climbing device for a road-rail vehicle. Background Art

[0002] A road-rail vehicle is a vehicle that can travel on both railway tracks and ordinary roads. There are many types of road-rail vehicles with wide applications, which can perform tasks such as transporting goods and personnel during road-rail conversion, emergency rescue and disaster relief, inspection of track lines, inspection of tunnel diseases, and temporary railway construction. They play an important role in both passenger and freight railway lines and subway operation departments.

[0003] Currently, the general method for a road-rail vehicle to get on and off the railway tracks is to use a lifting tool to lift the whole vehicle and place it on the railway tracks, and then lower the rail wheel mechanism to align with the railway tracks to achieve the switching from road driving to railway driving state. Or choose to get on the tracks at flat sections such as railway crossings and maintenance crossings. However, when the vehicle accidentally derails during railway travel, a lifting tool is still needed to restore the vehicle to the tracks. In many railway sections, it is even impossible to get the crane to the site, resulting in the road-rail vehicle being unable to move and causing the interruption of line operation.

[0004] To solve the problem of the road-rail vehicle's on-site track restoration function or the difficulty of getting on the tracks at any track section, a road-rail vehicle needs to carry a special on-track device with it, which can enable the road-rail vehicle to climb onto the railway tracks by its own power.

[0005] Existing rail climbing devices have problems such as large weight, difficult movement, or poor adaptability to railway sections, and cannot be used universally in passenger and freight railway sections and subway lines. Therefore, a rail climbing device that is convenient to carry and has strong universality is needed. Summary of the Invention

[0006] The purpose of the present application is to provide a rail climbing device for a road-rail vehicle to solve the defects in the prior art that the rail climbing device is inconvenient to move, has poor adaptability, and has limitations in the use area.

[0007] To achieve the above purpose, the present application is implemented by the following technical solutions:

[0008] A rail climbing device for a road-rail vehicle, which includes

[0009] a platform, with a ramp plate inclinedly connected to one side of the platform;

[0010] a rail clamping mechanism, which is arranged on the platform. The rail clamping mechanism is provided with a retractable inner clamping plate, and the inner clamping plate and the platform abut against the railway tracks and tension the platform;

[0011] a platform support mechanism, which is fixed on the platform. The platform support mechanism is provided with retractable movable legs for supporting the platform.

[0012] In a further solution of the present application, mounting holes are provided on one side of the platform, a connecting bent plate is fixed on the ramp plate, and the connecting bent plate is inserted into the mounting holes.

[0013] In a further solution of the present application, the platform support mechanism includes a vertical outer slideway and a movable support leg. The movable support leg is movably arranged in the vertical outer slideway. An adjusting lead screw is rotatably installed in the vertical outer slideway. A nut is horizontally fixed in the cavity of the movable support leg. The adjusting lead screw is in threaded engagement with the nut. By rotating the adjusting lead screw, the movable support leg can be telescoped.

[0014] In a further solution, a movable crank is detachably installed at one end of the adjusting lead screw close to the platform.

[0015] In a further solution of the present application, the rail clamping mechanism is installed at the bottom of the platform. The rail clamping mechanism includes a tensioning frame and a horizontal outer slideway. The tensioning frame is fixed at the bottom of the platform. The horizontal outer slideway is slidably connected to the tensioning frame. A tensioning lead screw is rotatably installed on the side plate of the tensioning frame close to the edge of the platform. One end of the tensioning lead screw entering the tensioning frame is in threaded engagement with the horizontal outer slideway. The inner clamping plate is fixed on the side of the horizontal outer slideway away from the tensioning lead screw. By rotating the tensioning lead screw, the inner clamping plate can be moved to contact the rail.

[0016] In a further solution, an outer clamping plate is also fixed on one side of the platform, and the outer clamping plate and the inner clamping plate are provided.

[0017] In a further solution, at least two groups of the rail clamping mechanisms are installed. The multiple groups of rail clamping mechanisms are evenly arranged on the other side of the platform.

[0018] In a further solution of the present application, anti-slip ribs are provided on the outer surfaces of the platform and the ramp plate.

[0019] The beneficial effects of the present application are as follows:

[0020] The rail climbing device designed in the present application is specifically used for the rubber wheels of vehicles in each direction. The rubber wheels close to the rail climbing device can climb onto the rail through the transition of the ramp plate and the platform. Among them, the rail clamping mechanism tensions the platform to ensure the safe transition of the vehicle. The overall height of the platform support mechanism can be adjusted by telescoping the movable support leg to meet the use under different subgrade conditions. When in use, it can be arranged and used in multiple directions. It can be arranged inside the rail or fixed outside the rail. At the same time, multiple rail climbing devices can be used in parallel. Moreover, the platform itself is located above the rail, which can adapt to various subgrade structures under the rail, significantly improving the adaptability of the device to railway sections.

[0021] In addition, when adjusting the overall height of the platform support mechanism, fitting and installing a movable crank on the adjusting lead screw significantly reduces the operation difficulty and improves the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use. Embodiment 1

[0028] In this embodiment, a rail climbing device for a road-rail vehicle is provided, which includes a platform 1; a ramp plate 2 is fixedly inclined on one side of the platform 1, and legs are provided at the bottom of the platform 1 for supporting the platform 1.

[0029] When the vehicle body derails on the track, the rail climbing devices in this embodiment are used singly or in parallel. The rubber wheels of each rail climbing device are arranged corresponding to each direction of the vehicle body, and the platform of each rail climbing device is arranged above the railway track. Here, the rubber wheels will drive onto the track again under the support and transition of the ramp plate and the platform, with simple operation and convenient use. Embodiment 2

[0030] Observe the attached Figure 1 and 2, this embodiment makes improvements on the basis of the solution of Embodiment 1. In Embodiment 1, the platform 1 is simply supported by legs, and its stability during use cannot be effectively guaranteed, there is a problem of easy movement, and the operations on the ground supported by the legs are different. If the platform is to be stably supported, a supporting surface in a good environment is required, and sometimes manual treatment, leveling or padding is needed, which is time-consuming and laborious.

[0031] In this embodiment, the legs in Embodiment 1 are cancelled, and two rail clamping mechanisms 3 and two platform supporting mechanisms 4 are added. The number of the rail clamping mechanisms 3 and the platform supporting mechanisms 4 is not limited to two, and can be increased or decreased according to the actual situation;

[0032] Among them, two rail clamping mechanisms 3 are horizontally installed at the bottom of one side of the platform 1, and two platform supporting mechanisms are vertically installed on the side of the platform 1. The rail clamping mechanism 3 is provided with a retractable inner clamping plate 3.4, and the inner clamping plate 3.4 abuts against the rail and tensions the platform 1. The platform supporting mechanism 4 is provided with a retractable movable leg 4.2 for supporting the platform 1. The movable leg 4.2 adjusts the height according to the base surface of different geographical environments, and cooperates with the rail to reduce the use of device materials and structures.

[0033] Observe the appendix Figure 3 , in this embodiment, mounting holes are provided on the wide side of the platform 1, a connecting bent plate 2.2 is fixed on the ramp plate, the connecting bent plate 2.2 is inserted into the mounting hole, and support ribs 1.4 are arranged on the platform 1 at the lower end of the mounting hole, and finally it is firmly clamped on the upper support ribs 1.4 by its own weight.

[0034] Continue to observe the appendix Figure 1 and 2 , in this embodiment, the rail clamping mechanism 3 is installed at the bottom of the platform 1. The rail clamping mechanism 3 includes a tensioning frame 3.2 and a horizontal outer slideway 1.3. The tensioning frame 3.2 is fixed at the bottom of the platform 1, and the horizontal outer slideway 1.3 is slidably connected to the tensioning frame 3.2. In actual production, a guiding port can be opened on the side of the tensioning frame 3.2, and the size of the guiding port is just for the horizontal outer slideway 1.3 to pass through. At the same time, the wall thickness of the guiding port is set wider, which has a certain guiding effect on the horizontal outer slideway 1.3. A tensioning lead screw 3.1 is rotatably installed on the side plate of the tensioning frame 3.2 close to the edge of the platform 1. One end of the tensioning lead screw 3.1 entering the tensioning frame 3.2 is in threaded fit with the horizontal outer slideway 1.3. In actual production, a nut is installed in the horizontal outer slideway 1.3, and the nut is in threaded fit with the tensioning lead screw 3.1. The inner clamping plate 3.4 is fixed on the side of the horizontal outer slideway 1.3 away from the tensioning lead screw 3.1. Rotate the tensioning lead screw 3.1 to make the inner clamping plate 3.4 contact the rail movably and perform the tensioning operation on the platform 1. In production, a hand wheel 3.3 is welded to the end of the tensioning lead screw 3.1.

[0035] To ensure the effectiveness of the tensioning of Platform 1, in this embodiment, an outer clamping plate 3.5 is also fixed to one side of the bottom of Platform 1. The number of outer clamping plates 3.5 corresponds to that of inner clamping plates 3.4, and the outer clamping plates 3.5 and the inner clamping plates 3.4 are arranged opposite to each other one by one. During use, the inner clamping plate 3.4 moves towards the railway track, and finally, both sides of the railway track are firmly clamped by the inner clamping plate 3.4 and the outer clamping plate 3.5.

[0036] Observe the attachment Figure 1 and 3 In this embodiment, the platform support mechanism 4 includes a vertical outer slideway 1.2 and a movable support leg 4.2. The movable support leg 4.2 is movably arranged in the vertical outer slideway 1.2. The combination of the vertical outer slideway 1.2 and the movable support leg 4.2 is similar to the insertion of two pipes. The movable support leg 4.2 can move within the vertical outer slideway 1.2. An adjustment lead screw 4.1 is rotatably installed in the vertical outer slideway 1.2. A nut is horizontally fixed in the cavity of the movable support leg 4.2. The adjustment lead screw 4.1 is in threaded fit with the nut. By rotating the adjustment lead screw 4.1, the movable support leg 4.2 can be telescoped. In actual production, the adjustment lead screw 4.1 is rotated according to the height of the terrain to ensure the levelness of Platform 1. To facilitate the rotation of the adjustment lead screw 4.1, a movable crank 5 is inserted into the top of the adjustment lead screw 4.1. In actual production, a square opening is provided on the top cross-section of the adjustment lead screw 4.1, and one end cross-section of the movable crank 5 is set to be square to achieve the insertion of the two.

[0037] In some other embodiments, anti-slip ribs 1.1 are provided on the outer surfaces of Platform 1 and the slope plate 2 to enhance the anti-slip performance of the plate surface.

[0038] Specific use;

[0039] When a vehicle derails on the track, observe the number and position of the tires at the derailment point, and place Platform 1 of this device on the track. It should be noted here that multiple climbing rail devices can be built simultaneously. At this time, whether the position of the platform support mechanism 4 is arranged inside or outside the track needs to be selected correspondingly according to the orientation of the tire detachment. Place the track in the area in front of the outer clamping plate 3.5 and the inner clamping plate 3.4, and then rotate the adjustment lead screw 4.1 to adjust the telescoping of the movable support leg 4.2 to make the whole platform in a horizontal state. Then rotate the tensioning lead screw 3.1 to control the movement of the inner clamping plate 3.4 until it cooperates with the outer clamping plate 3.5 to firmly support and fix the platform. At this time, the platform support mechanism 4 and the railway track clamping mechanism 3 jointly support Platform 1. Finally, insert the slope plate 2 on one side of Platform 1. The tires of the vehicle move onto Platform 1 through the slope plate 2 and finally transition to the track and drive normally along the track. The device is simple to install and avoids the intervention of large equipment such as cranes.
