Description

Technical Field

[0001] This application relates to the field of emergency rerailment technology for railway engineering vehicles derailed, and more specifically, to a hydraulic rerailing device installed on the vehicle. Background Technology

[0002] The existing vehicle-mounted hydraulic rerailing device includes a fixed body for the lateral movement mechanism, a sliding body for the lateral movement structure, a lateral movement cylinder, a lifting cylinder, and a base.

[0003] The fixed body of the lateral movement mechanism is installed at the bottom of the frame of the vehicle to be lifted; the upper part of the lifting cylinder is connected to the sliding body of the lateral movement mechanism, and the lower part of the lifting cylinder is connected to the base; the lateral movement cylinder connects the fixed body and the sliding body of the lateral movement mechanism.

[0004] During the repositioning process, the lifting cylinder raises the vehicle to a certain height, and the lateral cylinder actuates to reposition the vehicle back onto the track. During repositioning, as the vehicle rotates around the bogie at the other end, the repositioning device (i.e., the hydraulic rerailer) deflects slightly on the longitudinal section of the rail. Simultaneously, on the cross section of the rail, due to the change in the vehicle's position, the repositioning device (i.e., the hydraulic rerailer) also experiences a small deflection.

[0005] This results in the lifting cylinder not being perpendicular to the ground for extended periods, leading to extremely poor stability. Simultaneously, the lateral movement mechanism and cylinder experience reduced stress, which is even worse on ultra-high-speed railway lines. This results in short component lifespan, extremely poor stability, and low safety.

[0006] Therefore, the traditional hydraulic rerailers installed on the vehicle have poor stability, which is a technical problem that urgently needs to be solved by those skilled in the art.

[0007] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may contain information that is not part of the prior art known to those skilled in the art. Utility Model Content

[0008] This application provides a vehicle-mounted hydraulic rerailing device to solve the technical problem of poor stability of traditional vehicle-mounted hydraulic rerailing devices.

[0009] This application provides a vehicle-mounted hydraulic rerailing device, comprising:

[0010] A base assembly includes a base and a transverse mechanism, wherein the transverse mechanism includes a transverse mechanism fixing body and a transverse mechanism sliding body; wherein the transverse mechanism fixing body is fixed on the base, and the transverse mechanism sliding body and the transverse mechanism fixing body are slidably connected.

[0011] The upper ball seat and the lifting cylinder assembly are provided, wherein the upper ball seat is fixed to the lifting end of the lifting cylinder assembly; the upper ball seat is used to connect to the frame of the vehicle to be lifted.

[0012] The lifting cylinder assembly and the sliding body of the lateral movement mechanism are detachably connected.

[0013] The embodiments of this application, by adopting the above technical solutions, have the following technical effects:

[0014] In this embodiment of the vehicle-mounted hydraulic rerailer, the lifting cylinder assembly and the lateral movement mechanism slider are detachably connected. This allows the upper ball seat and the lifting cylinder assembly to be fixed as a single unit to the bottom of the vehicle frame. The base assembly is separately placed on the vehicle. When the vehicle-mounted hydraulic rerailer needs to operate, the lifting cylinder assembly and the lateral movement mechanism slider are then connected as a single unit, thus saving space. In this embodiment of the vehicle-mounted hydraulic rerailer, the lateral movement mechanism slider is located at the bottom of the entire device, resulting in less stress on the slider and better stability.

[0030] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0031] Example 1

[0032] like Figure 1-1 , Figure 1-2 , Figure 1-3 As shown in the illustration, a vehicle-mounted hydraulic rerailing device according to an embodiment of this application is mainly used for rerailing derailed railway vehicles. The vehicle-mounted hydraulic rerailing device according to this embodiment includes:

[0033] The base assembly 3 includes a base 301 and a transverse mechanism, wherein the transverse mechanism includes a transverse mechanism fixing body and a transverse mechanism sliding body; wherein the transverse mechanism fixing body is fixed on the base 301, and the transverse mechanism sliding body and the transverse mechanism fixing body are slidably connected.

[0034] The upper ball seat 1 and the lifting cylinder assembly 2 are provided. The upper ball seat 1 is fixed to the lifting end of the lifting cylinder assembly 2. The upper ball seat 1 is used to connect the frame of the vehicle to be lifted and re-railed. During the re-railing process, the lifting cylinder of the lifting cylinder assembly 2 is adjusted to a position perpendicular to the ground for stable support.

[0035] The lifting cylinder assembly 2 and the sliding body of the transverse mechanism are detachably connected.

[0036] In this embodiment of the hydraulic rerailer, which is installed on the vehicle, the lifting cylinder assembly 2 and the sliding body of the lateral mechanism are detachably connected. This allows the upper ball seat 1 and the lifting cylinder assembly 2 to be fixed as a single unit to the bottom of the vehicle frame. The base assembly 3 is separately placed on the vehicle. When the on-board hydraulic rerailer needs to operate, the lifting cylinder assembly 2 and the sliding body of the lateral mechanism are then connected as a single unit, thus saving space.

[0037] The base assembly 3 of the hydraulic rerailer is placed inside the vehicle end (ensuring that the base assembly 3 can be easily accessed from the vehicle end when needed, and is detachably connected to the lifting cylinder assembly). The upper ball seat 1 and the lifting cylinder assembly 2 can be fixed as a whole to the bottom of the vehicle frame (specifically, it can be fixed in the longitudinal position of the bogie).

[0038] like Figure 1-1 , Figure 1-2 , Figure 1-3 As shown in the embodiment of this application, the hydraulic rerailers installed on the vehicle are used in pairs.

[0039] In the vehicle-mounted hydraulic rerailer of this embodiment, the sliding body of the lateral movement mechanism is located at the bottom of the entire device. This results in a smaller force on the sliding body of the lateral movement mechanism and better stability.

[0040] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the fixed body of the transverse movement mechanism is the guide rail 30202, and the sliding body of the transverse movement mechanism is the slider 30201;

[0041] The guide rail 30202 is fixed on the base 301, and the slider 30201 is engaged with the guide rail 30202 and can move along the guide rail 30202; the lifting cylinder assembly 2 and the slider 30201 are detachably connected.

[0042] Specifically, the guide rail 30202 and the slider 30201 together form the linear guide rail 302.

[0043] The guide rail 30202 and slider 30201 have simple structures and strong ability to withstand forces, which makes the hydraulic rerailer installed on the vehicle in this application have good stability.

[0044] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the hydraulic rerailing device also includes:

[0045] A transverse hydraulic cylinder 4 is provided, with its two ends connected to the base 301 and the slider 30201, respectively, so as to drive the slider 30201 to move along the guide rail 30202.

[0046] The transverse hydraulic cylinder 4 can drive the slider 30201 to move smoothly along the guide rail 30202.

[0047] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the lifting cylinder assembly 2 includes:

[0048] Lifting cylinder seat 202;

[0049] The lifting cylinder 201 is fixed on the lifting cylinder seat 202;

[0050] The upper ball seat 1 is movably connected to the upper end of the lifting cylinder 201, and the lifting cylinder seat 202 and the slider 30201 are detachably connected.

[0051] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the upper ball seat 1 includes a ball seat 101 with a ball socket;

[0052] The piston rod end of the lifting cylinder 201 is provided with a ball head;

[0053] The piston rod of the lifting cylinder 201 has a ball joint with the ball seat 101, which allows the lifting cylinder 201 to adaptively adjust its angle as the vehicle deflects during the lifting and retraction process.

[0054] The ball joint connection between the piston rod of the lifting cylinder 201 and the ball seat 101 reduces the limiting of movement, does not generate additional stress, and improves safety.

[0055] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the upper ball seat 1 also includes a connecting rod 102 and a pin 103;

[0056] The connecting rod 102 is hinged to the side of the ball seat 101 via the pin 103 and the pin hole;

[0057] The connecting rod 102 is rotatably connected to and disconnected from the upper end of the lifting cylinder 201.

[0058] The connecting rod 102 rotates downwards to achieve a snap-fit ​​connection with the upper end of the lifting cylinder 201, and the upper ball seat 1 and the lifting cylinder 201 are connected together.

[0059] Link 102 is connected to the car body to connect the hydraulic rerailer to the car body.

[0060] When the hydraulic rerailer is not in operation, under the weight of the upper ball seat 1, the upper ball seat 1 is connected to the upper end of the lifting cylinder 201 via a snap-fit ​​connection. At this time, the ball head of the piston rod of the lifting cylinder 201 is not in contact with the ball socket of the ball seat 101.

[0061] When the hydraulic rerailer needs to work, the ball head of the piston rod of the lifting cylinder 201 is lifted upward until it contacts and engages with the ball socket of the ball seat 101.

[0062] The hydraulic rerailing device installed on the vehicle according to the embodiments of this application is used in pairs.

[0063] During the retraction process, as the vehicle rotates around the bogie at the other end, the hydraulic rerailer deflects to some extent on the longitudinal section of the rail; simultaneously, on the cross section of the rail, due to the change in the position of the vehicle body, the hydraulic rerailer also deflects slightly. Therefore, the piston rod end of the lifting cylinder 201 is equipped with a ball head, and the upper seat uses a ball seat 101 with a ball socket; one of the two hydraulic rerailer's transverse movement cylinders is active, and the other is follower-moving, and the base 301 is securely limited in both the longitudinal and transverse directions by relying on the rails and sleepers.

[0064] Specifically, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, each surface between the slider 30201 and the guide rail 30202 is provided with sufficient sealing and protection structures to ensure that the slider 30201 can slide smoothly on the guide rail 30202 even in a dirty environment.

[0065] During implementation, such as Figure 1-1 , Figure 1-2 , Figure 1-3 As shown, the transverse hydraulic cylinder 4 includes an active hydraulic cylinder and a follower hydraulic cylinder;

[0066] When the hydraulic rerailer is installed on the outer rail side, the active cylinder acts on the hydraulic rerailer; when the hydraulic rerailer is installed on the inner rail side, the follower cylinder acts on the hydraulic rerailer, in order to adapt to the start-up and rerailing requirements of different lines.

[0067] In practice, the oil source used by the lifting cylinder and the lateral cylinder is the power oil source configured in the vehicle, or a separately configured vehicle power oil source; and the oil source is fixed at the end of the vehicle.

[0068] The hydraulic rerailing device is also placed at the end of the vehicle to ensure safe operation.

[0069] During implementation, such as Figure 2-1 , Figure 2-2 , Figure 3-1 , Figure 3-2 , Figure 4 As shown, the hydraulic rerailer also includes a chain 51 and a pad block 52;

[0070] Under ultra-high-speed line operating conditions:

[0071] If the outer rail derails, the base 301 of the hydraulic rerailer on the inner rail side is fixed to the rail by the chain, and the base 301 of the hydraulic rerailer on the outer rail side is supported on the outer rail by the pad 52.

[0072] If the rail derails in the inner rail direction, the base 301 of the hydraulic rerailer on the inner rail side is fixed to the rail by the chain.

[0073] Under straight track conditions, the base 301 of the inner rail side hydraulic rerailer and the base of the outer rail side hydraulic rerailer are both laterally positioned by the chain and the pad block.

[0074] Specifically, the base assembly 3 is bolted to the lifting cylinder assembly 2, the transverse cylinder 4 is connected to the base 301 and the slider 30201 via a pin, and the lifting cylinder 201 and the lifting cylinder seat 202 are bolted together.

[0075] The scope of application of the hydraulic rerailing device in this application embodiment:

[0076] When a vehicle derails, if the wheel flange of the bogie wheelset does not extend beyond the end of the sleeper, the hydraulic rerailing device described in this application can be used for rerailing.

[0077] If the wheel flange of the vehicle's bogie wheelset extends beyond the end of the sleeper, and the wheels lack reliable support from the sleeper or other objects, the vehicle is at risk of overturning. To ensure personal safety, the hydraulic rerailing device described in this application should not be used for rerailing when the wheel flange of the vehicle's bogie wheelset extends beyond the end of the sleeper and there is no other reliable support.

[0078] Figure 2-1 A schematic diagram illustrating the method of using the vehicle-mounted hydraulic rerailer in the direction of derailment on a curve with superelevation, as described in this application embodiment; Figure 2-2 for Figure 2-1 Another perspective diagram. The right side is the outer side.

[0079] like Figure 2-1 and Figure 2-2 As shown, the method for handling derailment of the outer rail (i.e., the outermost rail) on a curve superelevation is as follows:

[0080] First, the hydraulic rerailer installed with the vehicle is placed at the end of the car body, and the longitudinal position of the bogie at the other end of the vehicle is fixed. The ball head of the piston rod of the lifting cylinder 201 is aligned with the ball socket of the ball seat 101. The lifting cylinders 201 of the inner rail side hydraulic rerailer and the outer rail side hydraulic rerailer are perpendicular to the ground, and the base 301 is firmly supported.

[0081] Secondly, the base 301 of the inner rail side hydraulic rerailer is pulled onto the rail by the chain 51, and the base 301 of the outer rail side hydraulic rerailer is placed on the rail laterally by the pad block 52 as needed.

[0082] Afterwards, when the lifting cylinder 201 of the outer rail side hydraulic rerailer is raised to the height where it can be moved laterally, the lateral movement cylinder 201 of the outer rail side hydraulic rerailer moves laterally. After the lateral movement cylinder 201 of the outer rail side hydraulic rerailer moves to the appropriate position, the lifting cylinder 201 of the outer rail side hydraulic rerailer descends. After the car body is stabilized, the base 301 of the outer rail side hydraulic rerailer is moved laterally and firmly supported to carry out the second rerailing operation.

[0083] As long as the wheel flange of the bogie does not extend beyond the end of the sleeper, the stroke of the lateral movement cylinder can ensure a single-pass repositioning. During the repositioning process, because the vehicle rotates around the bogie at the other end, the repositioning device will deflect to some extent on the longitudinal section of the rail. Simultaneously, on the transverse section of the rail, due to the change in the car body's position, the repositioning device will also deflect slightly. Therefore, the piston rod of the lifting cylinder 201 uses a ball head, the upper seat uses a ball seat, the inner rail of the lateral movement cylinder is active, the outer rail follows, and the base 301 has a reliable longitudinal limit.

[0084] Figure 3-1 This is a schematic diagram illustrating the method of using the hydraulic rerailing device in a curve superelevation where the inner rail derails, according to an embodiment of this application. Figure 3-2 for Figure 3-1 A schematic diagram from another angle. Figure 2-1 and Figure 2-2 The vehicle derailed towards the outer track. Figure 3-1 and Figure 3-2 The vehicle derailed towards the inner rail, with the left side being the inner side.

[0085] like Figure 3-1 and Figure 3-2 As shown, the method for handling derailment in the inner rail direction on a curve with superelevation is as follows:

[0086] First, the hydraulic rerailer installed with the vehicle is placed at the end of the car body, and the longitudinal position of the bogie at the other end of the vehicle is fixed. The ball head of the piston rod of the lifting cylinder 201 is aligned with the ball socket of the ball seat 101. The lifting cylinders 201 of the inner rail side hydraulic rerailer and the outer rail side hydraulic rerailer are perpendicular to the ground, and the base 301 is firmly supported.

[0087] Secondly, the base 301 of the inner rail side hydraulic rerailer is pulled onto the rail by chain 51.

[0088] Afterwards, when the lifting cylinder 201 of the inner rail side hydraulic rerailer is raised to a height that can be moved laterally, the lateral movement cylinder 201 of the inner rail side hydraulic rerailer moves laterally. After the lateral movement cylinder 201 of the inner rail side hydraulic rerailer moves to a suitable position, the lifting cylinder 201 of the inner rail side hydraulic rerailer descends. After the car body is stabilized, the base 301 of the inner rail side hydraulic rerailer is moved laterally and firmly supported to carry out the second rerailing operation.

[0089] Figure 4 This is a schematic diagram illustrating the method of using the hydraulic rerailer to derail on a straight track according to an embodiment of this application, showing the right side rail derailing.

[0090] like Figure 4 As shown, firstly, the hydraulic rerailer installed on the vehicle is placed at the end of the car body, and the longitudinal position of the bogie at the other end of the vehicle is fixed. The ball head of the piston rod of the lifting cylinder 201 is aligned with the ball socket of the ball seat 101. The lifting cylinders 201 of the inner rail side hydraulic rerailer and the outer rail side hydraulic rerailer are perpendicular to the ground, and the base 301 is firmly supported.

[0091] Secondly, the base 301 of the left hydraulic rerailer is pulled onto the rail by the chain 51, and the base 301 of the left hydraulic rerailer is placed horizontally on the rail by the pad block 52 as needed.

[0092] The base 301 of the right hydraulic rerailer is pulled onto the rail by a chain 51, and the base 301 of the right hydraulic rerailer is laterally supported on the rail by a pad 52 as needed.

[0093] Afterwards, when the lifting cylinder 201 of the right hydraulic rerailer is raised to the height where it can be moved laterally, the lateral cylinder 201 of the right hydraulic rerailer moves laterally. After the lateral cylinder 201 of the right hydraulic rerailer moves to the appropriate position, the lifting cylinder 201 of the right hydraulic rerailer lowers. After the car body is stabilized, the base 301 of the right hydraulic rerailer is moved laterally and firmly supported to carry out the second rerailing operation.

[0094] As long as the wheel flange of the bogie does not extend beyond the end of the sleeper, the stroke of the lateral movement cylinder can ensure a single-pass repositioning. During the repositioning process, because the vehicle rotates around the bogie at the other end, the repositioning device will deflect to a certain extent on the longitudinal section of the rail. Simultaneously, on the cross section of the rail, due to the change in the car body's position, the repositioning device will also deflect slightly. Therefore, the piston rod of the lifting cylinder 201 uses a ball joint, the upper seat uses a ball seat, one lateral movement cylinder is the active cylinder, and the other is the follower cylinder. The base 301 has a reliable longitudinal limit.
