Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rail transit technology, concretely relates to a rail locomotive convenient for rescue and rail transit system. BACKGROUND

[0002] Rail transit is a kind of traffic tool or transport system running on specific rail, and with the development of technology, rail transit presents more and more types, and the suspended rail transit system is a new type of rail transit, such as a rail transit system disclosed by CN112744255B and a suspended rail system disclosed by CN109664899B, which usually includes rail, rail locomotive (vehicle) arranged on the rail and car suspended below the rail locomotive connected with the rail, the rail is usually erected in the air and forms a cavity for the rail locomotive to run, the rail locomotive is arranged in the cavity and walks along the rail, thereby driving the car below to move forward.

[0003] In actual operation, when some small faults occur in the rail locomotive of the suspended rail transit system, the control system in the rail locomotive can be used to release the brake to unlock the walking wheel of the rail locomotive, so that the rescue vehicle can drag the rail locomotive with faults to achieve the purpose of rescue. However, some big faults, such as power failure or crash of the control system, power supply system, brake system failure and brake state, cannot normally release the brake and brake, so that the walking wheel of the rail locomotive is always in the locked state and cannot be dragged by the rescue vehicle. For common rail transit, such as train and subway, on-site destructive rescue can be used to release the brake and brake, such as cutting brake oil pipe or manually removing motor brake. However, in the suspended rail transit system, the rail locomotive runs in the cavity of the rail, the space in the cavity is relatively small, and the space between the rail locomotive and the side wall of the cavity is also small, so there is not enough space for on-site maintenance by rescue personnel. For example, it is very troublesome to disassemble the motor brake in the rail, and even the motor brake cannot be disassembled smoothly, which brings trouble to the rescue work. How to more conveniently and efficiently rescue the rail locomotive with locked walking wheel in the suspended rail transit system needs to be solved. SUMMARY

[0004] The utility model solves the above technical problems, provides a rail locomotive convenient for rescue, can more conveniently and efficiently complete rescue work under the condition that the walking wheel is locked, and the main idea is:

[0008] The power is in transmission connection with the lower support component and is used at least for driving the lower support component to move downwards to position two in the direction away from the frame.In the scheme, by configuring the rescue module on the track locomotive, the power and the lower support component in transmission connection are configured in the rescue module, and the two groups of spare wheels are configured in the lower support component, on the one hand, during the normal operation of the track locomotive, the lower support component is located at position one, at this time, the lower end of the spare wheel is higher than or flush with the lower end of the walking wheel, so that the spare wheel does not affect the normal operation of the track locomotive, when the track locomotive fails and the walking wheel is locked and cannot be pushed or pulled away, the support component can be driven to move downwards in the direction away from the frame by the power, in this process, the spacing between the support component and the frame gradually increases, the spare wheel gradually contacts and supports the entire locomotive body, and finally the support component reaches position two, at this time, the entire locomotive body is lifted as a whole, the locked walking wheel is separated from the walking surface of the track, and the locked walking wheel does not hinder the movement of the spare wheel along the track, so that the track locomotive can be smoothly moved along the track to the designated position under the action of the rescue vehicle, thereby achieving the purpose of more convenient and efficient rescue of the track locomotive.

[0009] To solve the lifting problem of the lower support component, further, the bearing structure further includes at least two swing members, one end of the swing member is rotatably connected to the frame, the other end of the swing member is rotatably connected to the lower support component, and the frame, the swing member and the lower support component form a parallelogram mechanism.Not only the lower support component can be lifted relative to the frame, but also the state of the entire bearing structure can be adjusted, and the parallelogram mechanism can effectively improve the bearing capacity of the entire bearing structure, so that the entire rescue module is more stable and reliable.

[0010] To solve the problem of more convenient cooperation with the power, further, the lower support member is also configured with a power adapting cooperation part, and the power is drivingly connected with the lower support member through the cooperation part.

[0011] Preferably, the power comprises a telescopic rod part, and the cooperation part is arranged at a position adapted to the rod part, and the power drives the lower support member to move through cooperation of the rod part and the cooperation part. In this scheme, the lower support member is driven to move along the length direction of the frame through extension or contraction of the rod part, and in combination with the characteristics of the parallelogram mechanism, the lower support member is not only moved along the length direction of the frame under the action of the power, but also moved downward in a direction away from the lower support member, so that the whole bearing structure can gradually jack up the whole locomotive body, thereby making the standby wheel contact the track and making the locked walking wheel be separated from the track, which will not hinder the track locomotive from moving, and the structure of the rescue module is simple and compact.

[0012] In some schemes, the power is rotatably connected with the frame, and the rod part is rotatably connected with the lower support member through the cooperation part. The power is assembled in a rotatable manner, which not only avoids interference in the extension process of the rod part, but also utilizes the extension of the rod part to drive the lower support member to move synchronously to the position two, so as to achieve the purpose of jacking up the whole locomotive body, and the structure is very simple, which is beneficial to reducing the volume and weight.

[0013] In some schemes, the power is fixedly installed on the frame, and the rod part corresponds to the cooperation part in the lower support member, and the rod part always corresponds to the cooperation part in the lower support member at least in the process that the lower support member moves from the position that the lower end of the standby wheel is flush with the lower end of the walking wheel to the position two. In this way, the extended rod part can contact and abut against the cooperation part in the lower support member, and the rod part always keeps in contact with the cooperation part in the lower support member in the process that the lower support member moves to the position two, so as to more stably transmit power and ensure that the power can drive the lower support member to move to the position two, so as to achieve the purpose of jacking up the whole locomotive body. Such design is beneficial to transmitting greater power and achieving better jacking effect.

[0014] Preferably, the cooperation part is a cooperation plate arranged on the lower support member, the cooperation plate is perpendicular to the length direction of the frame, and the rod part is perpendicular to the cooperation plate. In this way, the cooperation plate is provided with a forward pressure along the length direction of the frame, which is beneficial to transmitting greater power and achieving better jacking effect.

[0015] Preferably, an anti-collision part is installed at the end of the frame, and the power is connected with the anti-collision part. In this way, the power is located outside the end of the frame, which is more convenient for on-site operation and use.

[0016] Preferably, the power is a jack or an electric hydraulic cylinder. The performance is stable, the volume is small, and greater jacking power can be provided, which meets the requirements of rescue.

[0017] Preferably, the lower support member comprises two oppositely arranged and connected support parts, the support parts are configured as strip structures, the two support parts are arranged along the length direction of the frame respectively, and the two groups of spare wheels are rotatably arranged on the two support parts respectively; the upper end of the swing member is rotatably connected to the frame, and the lower end of the swing member is rotatably connected to the support parts, and the frame, the swing member and the support parts jointly form a parallelogram mechanism. Thus, one set of parallelogram mechanism can be formed on each side of the frame, and the two sets of parallelogram mechanisms act synchronously. Such design can further improve the carrying capacity of the rescue module, and can simplify the structure and facilitate the assembly of the lower support member, and the movement of the lower support member is less likely to interfere with the stable wheels, suspension frames and other structures below the locomotive body.

[0018] Preferably, the two support parts are connected through connecting pieces and / or matching parts.

[0019] To solve the problem of facilitating the installation of the swing member, further comprising a mounting bracket, the mounting bracket is fixed to the frame, the upper end of the swing member is rotatably connected to the frame, and the lower end of the swing member is rotatably connected to the support parts, and the mounting bracket, the swing member and the support parts jointly form a parallelogram mechanism.

[0020] To solve the problem that the lower support member moves excessively under the action of the power, resulting in that the gap between the walking wheels and the track is not up to standard or even no gap, further comprising a limiting structure arranged on the frame, the limiting structure is located on the side of the swing member away from the power, and when the lower support member moves to position two, the swing member abuts against the limiting structure. Thus, the limiting structure limits the swing member and the lower support member, so that the swing member can stably support the entire locomotive body. In addition, in some cases, the limiting structure can also support the swing member, improve the carrying capacity, and is also conducive to protecting the power in some cases.

[0021] To solve the problem of locking the lower support member at position one, further comprising a first constraint mechanism for constraining the lower support member at position one. When not in use, the lower support member is locked at position one through the first constraint mechanism, which can prevent the lower support member from interfering with the normal operation of the track locomotive, protect the spare wheels and improve the service life of the spare wheels, and reduce noise during normal operation.

[0043] Embodiment 1

[0044] The present embodiment provides a rail locomotive convenient for rescue, comprising a locomotive body and a rescue module, wherein the locomotive body can adopt a vehicle (or locomotive) in an existing rail transit system, in the present embodiment, the locomotive body comprises a frame 1, a driving module mounted on the frame 1, a rail changing module mounted on the frame 1, a control module, a brake module, etc., the driving module comprises a driving power 2 and two groups of walking wheels 11, each group of walking wheels 11 comprises at least two walking wheels 11, and the two groups of walking wheels 11 are arranged on the two sides of the frame 1, as shown in the drawings, so as to support the whole locomotive body by at least four walking wheels 11; the driving power 2 is in transmission connection with the walking wheels 11, when running, the walking wheels 11 on the two sides respectively contact the walking surfaces 61 on the two sides of the track, as shown in the drawings, so as to drive the walking wheels 11 to run along the track 6 by the driving power 2, in the implementation, the driving power 2 can be a motor or a gasoline engine, etc.; the rail changing module is usually arranged on the top of the frame 1, so as to cooperate with the turnout on the track 6, so that the locomotive body can smoothly pass through the track turnout; the control module is connected with the driving module, the rail changing module, the brake module and the like, so as to accurately control the running process of the locomotive body. Figure 1

[0045] In the present embodiment, the frame 1 mainly plays a role of bearing, and the frame 1 is also the mounting basis of other components. The structure and shape of the frame 1 can be determined according to actual needs, and the frame 1 as a whole can be constructed as a long strip structure (i.e., the length of the frame 1 is greater than or much greater than the width and height of the frame 1) for better adaptation to the track 6. In a more perfect implementation, the front end and the rear end of the frame 1 are also provided with anti-collision components 13, which can include anti-collision rods arranged along the length direction of the frame 1, as shown in the drawings. In a more perfect implementation, the lower end of the frame 1 is also provided with a suspension frame for suspending a car; the lower end of the frame 1 is also provided with a stabilizing wheel 12, as shown in the drawings. Figure 4 Figures 1-3 ​​As shown, in operation, the stabilizing wheels 12 are located in the gaps between the two walking surfaces 61 of the track 6, preventing the lateral movement of the locomotive body during operation, thereby effectively improving the stability of the entire track locomotive.

[0046] In implementation, the rescue module comprises a power 2 and a bearing structure, the bearing structure comprising a lower support member 3 and two groups of spare wheels 31, each group of spare wheels 31 comprising at least two spare wheels 31, such as Figures 2-4 As shown, each spare wheel 31 is rotatably arranged on the lower support member 3, for example, each spare wheel 31 can be rotatably connected to the lower support member 3 by means of shaft components, pins, bolts or screws, etc., so that each spare wheel 31 has a degree of freedom of rotation relative to the lower support member 3. At the same time, the two groups of spare wheels 31 are arranged on both sides of the length direction of the frame 1, such as Figures 2-4 As shown, so that when the walking wheels 11 are locked, the entire locomotive body is stably supported by at least four spare wheels 31; at the same time, the rotation center of the spare wheels 31 is parallel to the rotation center of the walking wheels 11, so that the locomotive body can also walk along the track by means of the spare wheels 31.

[0047] In implementation, the lower support member 3 is connected to the frame 1 in a lifting manner and can be switched between position one and position two; when the lower support member 3 is located at position one, the lower ends of the spare wheels 31 are higher than the lower ends of the walking wheels 11, so that when the walking wheels 11 run along the track 6, the spare wheels 31 do not contact the track 6, such as Figure 2 and Figure 8 As shown, without affecting the normal operation of the track locomotive, nor causing the wear of the spare wheels 31, which is conducive to improving the service life of the spare wheels 31. In other embodiments, when the lower support member 3 is located at position one, the lower ends of the spare wheels 31 can also be flush with the lower ends of the walking wheels 11, so that when the walking wheels 11 run along the track 6, the spare wheels 31 and the walking wheels 11 both contact the track 6, at this time, the spare wheels 31 also do not affect the normal operation of the track locomotive.

[0048] When the lower support member 3 is located at position two, the lower ends of the spare wheels 31 are lower than the lower ends of the walking wheels 11, such as Figure 3 and Figure 9 As shown, at this time, each spare wheel 31 contacts the walking surface 61 of the track 6, and each walking wheel 11 cannot contact the walking surface 61 of the track 6, and the walking wheel 11 is in a state of disengaging from the track; at this time, the spare wheels 31 bear the weight of the entire track locomotive, and the track locomotive can move along the track by rotating the spare wheels 31, so as to smoothly transfer and rescue the track locomotive that has failed.

[0049] In implementation, the power 2 is in transmission connection with the lower support member 3, and the power 2 is used at least to drive the lower support member 3 to move downwards in the direction away from the frame 1 to position two, that is, when the track locomotive fails to be pushed or pulled away due to the locked walking wheel 11, the support member can be driven to move downwards in the direction away from the frame 1 by the power 2, in the process, the distance between the support member and the frame 1 gradually increases, the standby wheel 31 gradually contacts and supports the entire locomotive body, and finally the support member reaches position two, at this time, as shown in Figure 3 and Figure 9 , the entire locomotive body is lifted as a whole, and the locked walking wheel 11 is separated from the walking surface 61 of the track; under the action of the external rescue vehicle, the track locomotive can be smoothly moved along the track to the designated position by the standby wheel 31, and the locked walking wheel 11 does not interfere with the movement of the track locomotive, so as to achieve the purpose of more convenient and efficient rescue.

[0050] In implementation, at position two, the distance between the walking wheel 11 and the track walking surface 61 can be determined according to actual needs, and in implementation, the distance can be as small as possible, for example, 0.5-3cm can be preferentially used, so as to ensure that the walking wheel 11 is separated from the walking surface 61 of the track, so that the height of the entire locomotive body lifted is small, and other structures in the locomotive body can still cooperate with the corresponding structures in the track, and interference and collision do not occur in the process of pushing or pulling away the track locomotive.

[0051] In order to facilitate the storage of the rescue module, in implementation, the size of the standby wheel 31 is much smaller than the size of the walking wheel 11, as shown in Figures 2-5 , which is conducive to reducing the volume of the entire rescue module, which can not only reduce the load of the entire track locomotive, but also does not greatly increase the volume of the entire track locomotive, and facilitates the storage of the rescue module at position one. In order to ensure the carrying capacity, in implementation, the number of standby wheels 31 can be increased, for example, more standby wheels 31 can be configured in each group of standby wheels 31, so that the number of standby wheels 31 in each group of standby wheels 31 can be preferentially configured as 4-16, and the specific number can be determined according to the actual load.

[0052] To make the lower support member 3 be able to lift relative to the frame 1, there are various embodiments, as an example, the power 2 can include at least two hydraulic cylinders arranged in vertical direction, the hydraulic cylinders are connected with the frame 1 and the lower support member 3 respectively, by making the hydraulic cylinders contract, the lower support member 3 is moved to position one, by making the hydraulic cylinders elongate, the lower support member 3 is moved from position one to position two. As another example, the bearing structure further includes at least two swing members 4, one end of the swing member 4 is rotatably connected with the frame 1, the other end of the swing member 4 is rotatably connected with the lower support member 3, the lower support member 3 is substantially parallel with the length direction of the frame 1, the frame 1, the swing member 4 and the lower support member 3 jointly constitute a parallelogram mechanism, as shown in Figure 7 and Figure 8 , not only makes the lower support member 3 be able to lift relative to the frame 1 to adjust the state of the whole bearing structure, but also by using the parallelogram mechanism, the bearing capacity of the whole bearing structure can be effectively improved, so that the whole rescue module is more stable and reliable.

[0053] In implementation, the swing member 4 can adopt rod-shaped or plate-shaped structure or other special-shaped structure etc.

[0054] In the embodiment, the lower support member 3 includes two oppositely arranged and connected support parts 32, as shown in Figure 2 and Figure 5 , the two support parts 32 have a gap between them, so that the two support parts 32 can correspond to two walking surfaces 61 in the track 6 respectively; in implementation, the support part 32 is preferably constructed as a strip-shaped structure, as shown in Figure 5 , and the two support parts 32 are arranged along the length direction of the frame 1. At this time, two groups of spare wheels 31 are rotatably arranged on the two support parts 32 respectively, so that each spare wheel 31 can exactly correspond to the walking surface 61 of the lower track 6, as shown in Figure 2 and Figure 3 . At the same time, at this time, the upper end of the swing member 4 is rotatably connected with the frame 1, and the lower end of the swing member 4 is rotatably connected with the support part 32, so that the frame 1, the swing member 4 and the support part 32 jointly constitute a parallelogram mechanism, as shown in Figure 7 and Figure 8 . Since there are two support parts 32, at least two swing members 4 need to be configured for each support part 32, so that the two support parts 32 can constitute a set of parallelogram mechanisms on both sides of the frame 1 respectively, as shown in Figure 2 and Figure 3As shown, the two sets of parallelogram mechanisms act synchronously. Such design can further improve the carrying capacity of the rescue module, and can simplify the structure, and can more conveniently assemble the lower support member 3, and the action of the lower support member 3 is not easy to interfere with the stable wheels 12, the suspension bracket and other structures below the vehicle body.

[0055] In implementation, the two support members 32 can be connected by a connecting piece, which can be arranged between the two support members 32, or arranged at the end of the support member 32, so that the two support members 32 can be connected as a whole to act synchronously under the action of the power 2. In implementation, the connecting piece can be arranged along the width direction of the vehicle frame 1.

[0056] In implementation, the number of swing members 4 arranged between the vehicle frame 1 and the support member 32 can be greater than 2, for example, 3, 4, 5, 6, etc., and preferably an even number of swing members 4 are arranged. When the number of swing members 4 arranged is greater than 2, each swing member 4 can be arranged along the length direction of the vehicle frame 1 to improve the carrying capacity. In implementation, the swing member 4 can be arranged below the vehicle frame 1 and between the vehicle frame 1 and the support member 32, or arranged on the side of the vehicle frame 1. When the swing member 4 is connected to the side of the vehicle frame 1, the space occupied is smaller, which is more conducive to miniaturization; for example, as shown in Figure 7 and Figure 8 As shown, the side of the support member 32 is rotatably connected with three pairs of swing members 4 (a total of 6 swing members 4), and the lower ends of the three pairs of swing members 4 are rotatably connected to the two sides of the support member 32 to form a parallelogram mechanism with stronger carrying capacity.

[0057] In order to facilitate cooperation with the power 2, in the present embodiment, the lower support member 3 is also configured with a cooperation part 33 adapted to the power 2, as shown in Figure 5 As shown, the power 2 is drivingly connected with the lower support member 3 through the cooperation part 33 to drive the lower support member 3 to act. Specifically, the power 2 includes an extensible rod part 21, as shown in Figure 5 and Figure 6As shown, the power 2 is connected with the lower support member 3 through the cooperation of the rod part 21 and the cooperation part 33, and can drive the lower support member 3 to move along the length direction of the frame 1 through the extension or contraction of the rod part 21. In combination with the characteristics of the parallelogram mechanism, the lower support member 3 is driven to move along the length direction of the frame 1 and also move downward in the direction away from the lower support member 3 under the action of the power 2, so that the whole bearing structure can gradually lift the whole locomotive body, thereby making the locked walking wheel 11 can be separated from the track 6 and will not hinder the track locomotive to move; at the same time, the spare wheels 31 can contact the track 6 and can move along the track, so that the track locomotive can be pulled or pushed away more smoothly and conveniently by the rescue vehicle, and the purpose of efficient rescue is achieved.

[0058] In an embodiment, one end of the power 2 is rotatably connected to the frame 1, for example, further comprising a support 14 rotatably connected to the frame 1, and the power 2 is fixedly installed on the support 14, as shown in Figure 7 So that the power 2 also has the freedom of rotation relative to the support 14; the other end of the power 2 is rotatably connected to the lower support member 3 through the cooperation part 33. When the lower support member 3 is at position one, the rod part 21 of the power 2 is in a contracted state; when the rod part 21 of the power 2 is extended, it can not only drive itself to rotate a certain angle relative to the frame 1, so that the extension process of the rod part 21 will not interfere; but also can drive the lower support member 3 to move synchronously to position two, so as to achieve the purpose of lifting the whole locomotive body. In implementation, the support 14 can be rotatably connected to the end of the frame 1, for example, the support 14 can be rotatably connected to the end of the frame 1 collision component 13, as shown in Figure 7 In implementation, the support 14 can be rotatably connected to the frame 1 through the cooperation of the hinge hole and the hinge piece 51, which will not be described here. In this embodiment, the cooperation part 33 can be a hinge hole or a hinge piece 51, and correspondingly, the end of the rod part 21 is provided with an adapted hinge piece 51 or a hinge hole, so as to realize the rotatable connection of the rod part 21 and the lower support member 3 through the cooperation of the hinge hole and the hinge piece 51. In implementation, the cooperation part 33 can be preferably configured on the support component 32 or the connecting piece of the lower support member 3, or can be configured on the shelf connected with the lower support member 3.

[0059] In another embodiment, the power 2 can be fixedly arranged on the frame 1, for example, the power 2 can be fixedly installed on the collision component 13 at the end of the frame 1, as shown in Figure 8As shown, the extension direction of the rod portion 21 of the power 2 can be consistent with the length direction of the frame 1, and the rod portion 21 corresponds to the matching portion 33 in the lower support member 3, and at least during the movement of the lower support member 3 from the position where the lower end of the standby wheel 31 is flush with the lower end of the traveling wheel 11 to the position two, the rod portion 21 always corresponds to the matching portion 33 of the lower support member 3. So that the extended rod portion 21 can contact and abut against the matching portion 33 in the lower support member 3, and during the movement of the lower support member 3 to the position two, the rod portion 21 always maintains the contact state with the matching portion 33 in the lower support member 3, so as to more stably transmit power, and ensure that the power 2 can drive the lower support member 3 to move to the position two, so as to achieve the purpose of lifting the entire motorcycle body, and such design is beneficial to transmitting greater power 2.

[0060] In implementation, the matching portion 33 can be preferentially arranged at the end of the lower support member 3, for example, the matching portion 33 can be a matching plate arranged at the end of the support member 32, such as Figure 5 and Figure 8 As shown, the matching plate can be perpendicular to the length direction of the frame 1, so that the rod portion 21 can be perpendicular to the matching plate, so as to provide the matching plate with a positive pressure along the length direction of the frame 1, which is beneficial to transmitting greater power 2; of course, the matching portion 33 can also be a connecting piece in the lower support member 3, at this time, the connecting piece can be preferentially constructed as a plate structure and directly opposite the rod portion 21.

[0061] In the embodiment, the power 2 can preferentially adopt a jack, for example, the jack can adopt a manual jack, and in use, the rescuer can manually extend or reset the rod portion 21 in the jack; in addition, in implementation, the power 2 can also adopt an electric jack or a pneumatic jack, so as to more labor-savingly drive the lower support member 3 to act, and of course, at this time, a corresponding independent power supply and independent air source need to be configured for the electric jack and the pneumatic jack, so that the power 2 can normally operate, and as an example, the required power supply or air source can be configured on the rescue vehicle, so as to simplify the entire rescue module. Of course, in implementation, the power 2 can also adopt an electric hydraulic cylinder.

[0062] In a more complete embodiment, a first constraint mechanism is further included to constrain the lower support member 3 to the position one; to ensure that the lower support member 3 can be locked to the position one by the first constraint mechanism when not in use, on one hand, to prevent the lower support member 3 from interfering with the normal operation of the rail vehicle, on the other hand, to facilitate the protection of the spare wheel 31 and to improve the service life of the spare wheel 31, in addition, to facilitate the reduction of noise during normal operation. In implementation, the first constraint mechanism has various embodiments, for example, the first constraint mechanism can be a rope, a steel wire or an iron wire, etc., when the lower support member 3 is at the position one, the lower support member 3 can be tied to the vehicle frame 1 by the first constraint mechanism, when rescue is needed, the lower support member 3 can be untied, which is very convenient. For another example, as shown in Figure 12 , the first constraint mechanism can include a positioning hole 15 configured on the vehicle frame 1, a first constraint hole 34 configured on the lower support member 3, and a fastener 52 adapted to the positioning hole 15 and the first constraint hole 34, the first constraint hole 34 is adapted to the positioning hole 15, when the lower support member 3 is at the position one, the first constraint hole 34 corresponds to the positioning hole 15, so that the lower support member 3 can be detachably locked to the vehicle frame 1 by the fastener 52; when rescue is needed, the fastener 52 can be disassembled to be unlocked. The first constraint mechanism also has many other embodiments, which will not be illustrated one by one here. In implementation, the fastener 52 can be a pin, a bolt pair, etc.

[0063] It can be understood that in implementation, when the lower support member 3 is driven by the power 2 to move to the position two, in some embodiments, at this time, the swing member 4 can be in an inclined state (the swing member 4 has not been turned to the vertical position), the power 2 plays a role in limiting the movement of the lower support member 3 to the position one (i.e., limiting the reverse movement), so that the swing member 4 can stably support the entire vehicle body, as shown in Figure 8 ; while in other embodiments, at this time, the swing member 4 can be in a vertical state, as shown in Figure 9 , the power 2 also plays a role in limiting the movement of the lower support member 3 to the position one (i.e., limiting the reverse movement). In order to prevent the swing member 4 from being turned too much under the action of the power 2, causing the gap between the running wheel 11 and the rail to be smaller, in a further embodiment, a limiting structure 16 is further included, as shown in Figure 10 and Figure 11As shown, the limiting structure 16 can be a limiting block or a limiting rod arranged on the frame 1, the limiting structure 16 can be arranged on one side of the swing member 4, and the power 2 and the limiting structure 16 are respectively located on different sides of the swing member 4, when the lower support member 3 moves to the position two, the swing member 4 is just rotated to the position abutting against the limiting structure 16 under the action of the power 2, thereby the swing member 4 and the lower support member 3 are limited by the limiting structure 16, so that the swing member 4 can stably support the whole motorcycle body. It can be understood that, if when the lower support member 3 moves to the position two, the swing member 4 has already rotated through the vertical position, as shown in the figure, at this time, the limiting structure 16 can not only play a limiting role, but also play a role of supporting the swing member 4, improving the carrying capacity and stability, at this time, the load borne by the power 2 is relatively small, which is beneficial to the protection of the power 2. Figure 11

[0064] In a more perfect embodiment, a second constraint mechanism for constraining the lower support member 3 to the position two is further included, so as to improve the stability and reliability of the rescue module during movement, in implementation, the second constraint mechanism has various embodiments, for example, the second constraint mechanism can include a positioning hole 15 arranged on the frame 1, a second constraint hole 35 configured on the lower support member 3, and a fastener 52 adapted to the positioning hole 15 and the second constraint hole 35, the second constraint hole 35 is adapted to the positioning hole 15, when the lower support member 3 is located at the position two, the second constraint hole 35 corresponds to the positioning hole 15, as shown in the figure, so that the lower support member 3 can be detachably locked to the frame 1 by the fastener 52, preventing the position of the lower support member 3 from changing, in implementation, the fastener 52 can be a pin or a bolt pair, etc. It can be understood that, in implementation, the first constraint mechanism and the second constraint mechanism can share one positioning hole 15, as shown in the figures, or two positioning holes 15 can be respectively configured. Figure 12 Figure 13 Figure 12 Figure 13

[0065] In the present embodiment, the rotatable connection of two components (such as the swing member 4 and the frame 1, the swing member 4 and the lower support member 3) can be realized by using the existing technology, for example, the swing member 4 and the lower support member 3 (or the support member 32) are both configured with mutually adapted hinge holes, a hinge member 51 adapted to the hinge holes is arranged in the hinge holes, the hinge member 51 can be a shaft component, a pin, a bolt or a screw, etc., so that the rotatable connection of the swing member 4 and the lower support member 3 (or the support member 32) can be realized by the cooperation of the hinge member 51 and the hinge holes. Similarly, the swing member 4 and the frame 1 are both configured with mutually adapted hinge holes, a hinge member 51 adapted to the hinge holes is arranged in the hinge holes, the rotatable connection of the swing member 4 and the frame 1 can also be realized by the cooperation of the hinge member 51 and the hinge holes. ​​​​​

[0066] Embodiment 2

[0067] The main difference between the present embodiment and the above-mentioned embodiment 1 is that the lower support member 3 is an integrally formed member in the track vehicle provided in the present embodiment, and the lower support member 3 is arranged below the vehicle frame 1, and a plurality of avoiding holes 17 are formed on the support member so as to avoid the interference with the suspension frame and the stabilizer wheel 12 etc. below the vehicle frame 1. The swing member 4 can be arranged between the vehicle frame 1 and the lower support member 3, as shown in Figs. 2 and 3, in which case at least two swing members 4 are required to be arranged, of course, the swing member 4 can also be arranged on the outside of the vehicle frame 1, in which case at least four swing members 4 are required to be arranged; when the lower support member 3 is located at position one, the lower support member 3 is close to or in contact with the lower end of the vehicle frame 1; when the lower support member 3 is located at position two, the distance between the lower support member 3 and the lower end of the vehicle frame 1 is increased. Figure 14 Figure 15 As shown in Figs. 2 and 3, when the lower support member 3 is located at position one, the lower support member 3 is close to or in contact with the lower end of the vehicle frame 1; when the lower support member 3 is located at position two, the distance between the lower support member 3 and the lower end of the vehicle frame 1 is increased.

[0068] Similarly, in order to improve the carrying capacity, the number of swing members 4 arranged between the vehicle frame 1 and the lower support member 3 can be greater than 2, for example, 3, 4, 5, 6, etc. can be arranged, and even number of swing members 4 is preferred, when the number of swing members 4 arranged is greater than 2, each swing member 4 can be arranged along the length direction of the vehicle frame 1, or along the width direction of the vehicle frame 1, both of which can improve the carrying capacity.

[0069] Of course, in the implementation, the swing member 4 can also be arranged on both sides of the length direction of the vehicle frame 1, in which case at least two swing members 4 are required to be arranged on any one side of the two sides of the vehicle frame 1, which can also improve the carrying capacity.

[0070] Similarly, in order to facilitate cooperation with the power 2, in the present embodiment, the end of the lower support member 3 is configured with a matching part 33 adapted to the power 2, as shown in Figs. 2 and 3, at least so that the lower support member 3 moves from the position where the lower end of the standby wheel 31 is flush with the lower end of the running wheel 11 to position two, the rod part 21 of the power 2 always corresponds to the matching part 33 of the lower support member 3, so as to provide stable power 2 for the movement of the lower support member 3 to position two. Figure 15

[0071] The other structures can be the same as those of embodiment 2, which will not be described here.

[0072] Embodiment 3

[0073] ​​In order to facilitate assembly, the main difference between the embodiment 3 and the above-mentioned embodiments is that the track vehicle provided by the embodiment further comprises a mounting frame fixed to the vehicle frame 1, the upper end of the swing member 4 is rotatably connected to the vehicle frame 1, and the lower end of the swing member 4 is rotatably connected to the support component 32, and the mounting frame, the swing member 4 and the support component 32 jointly constitute a parallelogram mechanism. Not only can the effect of rotatably connecting the swing member 4 to the vehicle frame 1 be achieved, but the installation of the swing member 4 is also facilitated. In the implementation, the mounting frame can be welded or riveted to the vehicle frame 1, or can be detachably mounted to the vehicle frame 1 through fasteners 52 such as bolts or screws.

When the running wheels 11 are locked and need to be rescued, the rescue vehicle can be moved to one end of the track vehicle along the track 6, the power 2 arranged at the end is started and drives the lower support member 3 to move to the position two, so that the two groups of standby wheels 31 respectively contact the two running surfaces 61 and lift the entire track vehicle, so that the running wheels 11 are separated from the running surfaces 61, and thus the track vehicle can be pushed or pulled by the rescue vehicle along the track 6 to a designated position, so as to achieve the purpose of efficient rescue.

[0076] It can be understood that in other embodiments, the track 6 can also not comprise the shell 62, that is, the track vehicle in the embodiment 1 is also applicable to running on the track 6 without the cavity 63. In the embodiment, the track 6 can be arranged on the ground or underground; in addition, the track can also be arranged in the air, at this time, the track transportation system is a suspended track transportation system, and at this time, in a more perfect scheme, a car is further included, the car can be connected to the track vehicle through a suspension frame and suspended below the track 6, so as to drive the car to run along the track by the track vehicle.
