Abstract
Description
Technical Field
[0001] This application relates to the field of railway maintenance equipment technology, specifically a wheelset fault deviation device. Background Technology
[0002] In the railway transportation system, wheelsets are an important component of trains, and their performance directly affects the safety and comfort of the train. The main function of wheelsets is to bear the heavy load of the train and maintain its stable running trajectory. Therefore, wheelset failure has always been one of the key safety hazards that need to be paid attention to in railway operation.
[0003] Common types of wheelset failures include wheel flange wear, wheelset deformation, and poor wheel-rail contact. The safe operation of railway trains is related to the orderly operation of people's normal lives. If a failure occurs in the mechanical parts of the train's running gear, such as wheelset bearing burnout, gear seizure, or gearbox suspension failure, the train will be unable to be towed away from the scene by itself or passively, causing the line to be paralyzed. Since the wheelset is damaged and deformed and cannot continue to move, if the staff forcibly tows it, it will lead to a serious accident of derailment.
[0004] Therefore, this application provides a wheelset failure tracker to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a wheelset failure traction device, which aims to solve the problem mentioned in the background art where trains are unable to be pulled out of the field by themselves or passively, causing track paralysis, and trains cannot continue to move due to wheelset damage and deformation.
[0006] To achieve the above objectives, this application provides the following technical solution: a wheelset failure scooter, comprising a rail and a towing mechanism symmetrically arranged on the rail;
[0007] The towing mechanism includes an outer support plate and an inner support plate arranged opposite to each other. Wheel supports are symmetrically distributed between the outer support plate and the inner support plate. Both ends of the outer support plate and the inner support plate are fitted with pins, and one end of the pin passes through the outer support plate and is sleeved with a nut. Wheel supports are provided between the outer support plate and the inner support plate. Two sets of traveling wheels are equidistantly arranged between the two wheel supports. The gap between the mounting hole and the pin is 0.5mm, allowing the wheel supports to swing slightly to adapt to uneven rails.
[0008] Preferably, the wheel support has a mounting hole, which is fixedly fitted onto the pin of the bolt, allowing the wheel support to be fixed on the bolt, thereby providing support for the wheelset and preventing rigid collision between the wheelset and the rail.
[0009] Preferably, the inner support plate is provided with three sets of set bolts along its length. The three sets of set bolts pass through the outer support plate and are fixed by nuts. By pre-tightening the nuts, the connection rigidity between the outer support plate and the inner support plate is improved.
[0010] Preferably, the three sets of set bolts are arranged in a V-shape.
[0011] Preferably, the inner support plate has symmetrically distributed through pins, the pin rods of the through pins are inserted into the traveling wheels, and one end of the through pin passes through the outer support plate and is fixed by a nut.
[0012] Preferably, two sets of connecting rods are installed at equal intervals between the two inner support plates.
[0013] This fault-lifting device mainly consists of a running wheel, wheel support, inner and outer support plates, connecting rods, pins, set bolts, nuts, etc. It has the advantages of being lightweight, small in size, and easy and quick to assemble. It is suitable for use when the wheelset of a railway vehicle is affected by problems such as wheelset failure. The faulty wheelset is lifted and used as a temporary support to restore the locomotive or vehicle to operation within a limited speed, thus playing an emergency rescue role.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0020] This embodiment provides a wheelset failure scooter, such as Figure 1-3 As shown, the fault-traversing device includes a rail 1 and a towing mechanism symmetrically arranged on the rail 1.
[0021] The towing mechanism includes an outer support plate 2 and an inner support plate 3 arranged opposite to each other. Wheel supports 4 are symmetrically distributed between the outer support plate 2 and the inner support plate 3. Pins 7 are inserted at both ends of the outer support plate 2 and the inner support plate 3. The pins 7 pass through one end of the outer support plate 2 and are connected by a nut. Wheel supports 4 are arranged between the outer support plate 2 and the inner support plate 3. Two sets of traveling wheels 5 are arranged at equal intervals between the two wheel supports 4.
[0022] Specifically, the outer support plate 2 and the inner support plate 3 form a frame structure through the pin 7. The wheel support 4 is fixedly mounted on the pin 7 to support the wheelset. The running wheel 5 is installed between the wheel support 4. The running wheel 5 rolls on the rail 1 to enable the dragging of the faulty wheelset. The nuts at both ends of the pin 7 are used to fix the distance between the outer support plate 2 and the inner support plate 3 to adapt to different track gauge requirements. The pin 7 bears the lateral load during dragging.
[0023] The wheel support 4 has a mounting hole 41, which is fixedly fitted onto the pin of the pin 7.
[0024] More specifically, the mounting hole 41 of the wheel support 4 is fitted onto the pin 7 to form a clearance fit, allowing the wheel support 4 to be fixed on the pin 7, thereby providing support for the wheelset and preventing the wheelset from rigidly colliding with the rail 1.
[0025] Three sets of set bolts 6 are provided on the inner support plate 3 along its length. The three sets of set bolts 6 pass through the outer support plate 2 and are fixed by nuts. The three sets of set bolts 6 are distributed in a V-shape.
[0026] Furthermore, the three sets of set bolts 6 are distributed in a 60° V-shape, passing through the outer support plate 2 from the inner support plate 3, and are pre-tightened by nuts to improve the connection rigidity between the outer support plate 2 and the inner support plate 3.
[0027] The inner support plate 3 has symmetrically distributed through pins 8. The pins of the through pins 8 are inserted into the traveling wheels 5, and one end of the through pins 8 passes through the outer support plate 2 and is fixed by a nut.
[0028] It should be noted that the pin 8 passes through the hub of the running wheel 5 and the inner support plate 3, and is locked at both ends with nuts to form a rigid connection, ensuring that the running wheel 5 rotates around the pin 8.
[0029] Two sets of connecting rods 9 are installed at equal intervals between the two inner support plates 3.
[0030] It is worth mentioning that the two sets of connecting rods 9 are welded to both ends between the two sets of inner support plates 3 to form a truss structure, which improves the lateral stiffness of the left and right inner support plates 3 and suppresses lateral swaying during dragging.
[0031] In use, the wheel lifter consists of a running wheel 5, wheel support 4, inner support plate 3 and outer support plate 2, connecting rod 9, through pin 8, set bolt 6, and nut. When a problem occurs with the wheelset of a railway vehicle and affects its operation, the workers place the wheel lifter on the section of rail 1 where the wheelset is damaged. Using jacks, the wheelset is lifted, placing the damaged wheelset between the two wheel supports. The wheel lifter is then used to lift the faulty wheelset, which serves as a temporary support. The wheel lifter rotates in place of the wheels, allowing the locomotive or rolling stock to resume operation within a limited speed. This enables the faulty train to leave the scene as quickly as possible and rapidly restores the operation of the line, playing a role in emergency rescue.
[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
